Un appareil de ce genre, par exemple un interrupteur différentiel, possède, dans le boîtier modulaire muni de ses bornes de raccordements usuelles, un ou plusieurs contacts fixes coopérant avec un ou plusieurs contacts mobiles, un mécanisme pouvant être commandé manuellement pour basculer le(s) contact(s) mobile(s) vers le(s) contact(s) fixe(s), et un organe d'actionnement, tel qu'un relais, susceptible de provoquer le basculement en sens contraire du contact mobile pour provoquer l'ouverture des contacts, ce relais étant dépendant d'un élément de mesure, par exemple un tore, qui se trouve excité par induction en cas de déséquilibre dans les conducteurs primaires qui le traversent. Les appareils de ce genre sont encombrants et relativement chers à pro­duire. Ils nécessitent de fabriquer de nombreuses pièces particulières pour chaque type d'appareil et posent des problèmes de montage, de gestion de stock et de maintenance. Les disjoncteurs et les disjoncteurs différentiels présentent les mêmes genres d'inconvénients.Currently, protective devices such as differential switches, circuit breakers, differential circuit breakers are produced in modular housings. An apparatus of this kind, for example a differential switch, has, in the modular housing provided with its usual connection terminals, one or more fixed contacts cooperating with one or more movable contacts, a mechanism that can be manually controlled to switch the movable contact (s) towards the fixed contact (s), and an actuating member, such as a relay, capable of causing the tilting in the opposite direction of the movable contact to cause the opening of the contacts, this relay being dependent on a measuring element, for example a toroid, which is excited by induction in the event of an imbalance in the primary conductors which pass through it. Devices of this kind are bulky and relatively expensive to produce. They require the manufacture of many specific parts for each type of device and pose problems of assembly, stock management and maintenance. Circuit breakers and differential circuit breakers have the same kinds of drawbacks.

Dans une forme de réalisation préférée, les zones peu­vent être distribuées les unes par rapport aux autres, comme suit, étant entendu que, par convention, la partie de l'appareil comportant les moyens de fixation amovibles sur un rail de coffret de distribution électrique est appelée le bas et la partie opposée, par laquelle peut passer un organe de manoeuvre tel qu'une manette, est appelée le haut :

La zone de mesure est avantageusement constituée de parois formant un logement sensiblement cylindrique dans lequel peut s'ajuster un ensemble de tores différentielsThe measurement zone advantageously consists of walls forming a substantially cylindrical housing in which a set of differential toroids can be adjusted.

Le boîtier peut avantageusement constituer un simple habillage revêtant l'ensemble de l'appareil, cet habillage étant pourvu de passages permettant l'accès aux bornes ainsi que le passage du ou des organes de manoeuvre tels que manettes ou leviers.The housing can advantageously constitute a simple covering covering the entire apparatus, this covering being provided with passages allowing access to the terminals as well as the passage of the operating member (s) such as levers or levers.

On préfère que cet habillage porte les moyens d'accrochage sur un rail.It is preferred that this covering carries the attachment means on a rail.

Dans une forme de réalisation particulièrement préférée, la pièce de structure comporte une cloison médiane divisant l'appareil en deux parties latérales, ladite cloison médiane étant interrompue au niveau de la zone de mesure et de la zone de moyens de déclenchement recevant un relais d'interrupteur différentiel, ladite cloison médiane, de préférence dédoublée aux deux extrémités, y définissant quatre zones de bornes grâce à deux cloisons transversales situées à proximité des deux extrémités.In a particularly preferred embodiment, the structural part comprises a central partition dividing the device into two lateral parts, said central partition being interrupted at the level of the measurement zone and of the trigger means zone receiving a relay. differential switch, said central partition, preferably split at both ends, defining there four terminal zones by means of two transverse partitions located near the two ends.

A partir de l'une de ces cloisons transversales est définie une zone de mesure formant de préférence un réceptacle susceptible de recevoir un tore de détection alors qu'à partir de l'autre cloison transversale s'étendent, à un certain niveau, et de part et d'autre de la cloison médiane, des cloisons parallèles au fond de l'appareil pour définir des zones de contact situées au bas de l'appareil et, de l'autre côté, d'une part, une partie de la zone de mécanisme et de l'autre côté, la zone de moyens de déclenchement magnétique, l'ensemble étant surmonté, grâce à la présence d'une cloison transversale à un niveau plus élevé, d'une zone de moyens de déclenchement recevant un relais. Au centre de l'appareil et verticalement, c'est-à-dire de haut en bas, s'étendent, de part et d'autre de la cloison médiane, le reste de la zone de mécanisme de serrure de déclenchement de contact et, d'autre part, une zone de moyens de déclenchement recevant un organe de déclenchement thermique tel qu'une bilame.From one of these transverse partitions is defined a measurement area preferably forming a receptacle capable of receiving a detection toroid while from the other transverse partition extend, at a certain level, and on either side of the middle partition, partitions parallel to the bottom of the device for defining contact areas located at the bottom of the device and, on the other side, on the one hand, part of the mechanism area and on the other side, the area of magnetic trip means , the assembly being surmounted, by virtue of the presence of a transverse partition at a higher level, of a zone of tripping means receiving a relay. In the center of the device and vertically, that is to say from top to bottom, extend, on either side of the central partition, the rest of the zone of contact trigger lock mechanism and , on the other hand, a trigger means area receiving a thermal trigger member such as a bimetallic strip.

L'appareil représenté est habillé par un boîtier réalisé sous forme de deux demi-boîtiers 1, 2, à savoir un demi-boîtier supérieur 1 et un demi-boîtier inférieur 2, les deux boîtiers étant raccordés au niveau d'une ligne de séparation 3. Le demi-boîtier inférieur 2 présente, de façon usuelle, des moyens d'accrochage 4, 5 sur un rail alors que le demi-boîtier supérieur 1 présente deux paires d'épaulements successifs 6, 7 et un sommet 8 muni d'un pas­sage 9 pour le levier d'actionnement manuel du mécanisme. Les bords extrêmes du boîtier présentent chacun, dans le demi-boîtier inférieur 2, chaque fois deux ouvertures 10 autorisant respectivement l'accès aux différentes bornes à cage 12, 13 de l'appareil et les épaulements 7 présentent chacun deux passages 11 pour l'accès aux vis de borne respectives des cages.The device shown is covered by a box made in the form of two half-boxes 1, 2, namely an upper half-box 1 and a lower half-box 2, the two boxes being connected at a separation line. 3. The lower half-casing 2 usually has hooking means 4, 5 on a rail, while the upper half-casing 1 has two pairs of successive shoulders 6, 7 and an apex 8 provided with a passage 9 for the manual actuation lever of the mechanism. The extreme edges of the housing each have, in the lower half-housing 2, each time two openings 10 respectively authorizing access to the different cage terminals 12, 13 of the apparatus and the shoulders 7 each have two passages 11 for the access to the respective terminal screws of the cages.

A l'intérieur du boîtier, l'appareil est monté sur une pièce de structure centrale 20 réalisée par injection moulage. Cette pièce 20 présente une forme générale à peu près symétrique par rapport à un plan vertical médian que matérialise une cloison médiane 21. A faible distance de l'une des extrémités, la cloison médiane 21 se raccorde à une cloison transversale 22 au-delà de laquelle des cloisons dédoublées 23 définissent, avec la cloison transversale 22, deux zones de bornes A destinées à recevoir les bornes de l'appareil, ces zones de bornes étant limitées à la partie inférieure par de petites parois horizontales 25 s'étendant des cloisons dédoublées 23 et des cloisons transversales, pour recevoir et isoler les bornes 12 respectives.Inside the housing, the device is mounted on a central structural part 20 produced by injection molding. This part 20 has a general shape which is roughly symmetrical with respect to a vertical median plane embodied by a central partition 21. A short distance from one of the ends, the central partition 21 is connected to a transverse partition 22 beyond which of the divided partitions 23 define, with the transverse partition 22, two terminal zones A intended to receive the terminals of the device, these terminal zones being limited to the lower part by small horizontal walls 25 extending from the divided partitions 23 and transverse partitions, to receive and isolate the respective terminals 12.

La cloison 21 se poursuit, en direction de l'autre extrémité, peu après le milieu de l'appareil, par une seconde cloison transversale 26 à partir de laquelle s'étendent deux cloisons 27 se dirigeant d'abord parallèlement vers l'extrémité puis convergent de façon cylindrique pour former, avec un fond 28, une zone de mesure B susceptible de recevoir un agencement de tore de mesure différentielle. Dans la partie centrale de la zone B formant logement de tore se trouve un fût cylindrique 30 qui se rac­corde, à la partie inférieure, à un prolongement de la cloison 21 passant sous le fond 28, lequel présente, en cet emplacement, de part et d'autre de ce prolongement de cloison 21, un passage en demi-lune 31.The partition 21 is continued, in the direction of the other end, shortly after the middle of the apparatus, by a second transverse partition 26 from which extend two partitions 27 which are directed first. parallel towards the end and then converging in a cylindrical manner to form, with a bottom 28, a measurement zone B capable of receiving an arrangement of differential measurement toroid. In the central part of the zone B forming a toroid housing is a cylindrical barrel 30 which is connected, at the lower part, to an extension of the partition 21 passing under the bottom 28, which has, in this location, in part and on the other side of this partition extension 21, a half-moon passage 31.

Les cloisons 27, de même que le prolongement de cloison 21, se raccordent à une paroi transversale 32 à partir de laquelle s'étendent des cloisons dédoublées 33 analogues aux cloisons 23 de façon à former deux autres zones de bornes A délimitées, à la partie inférieure, par des parois de fond 34 perpendiculaires aux parois 32 et 33 et analogues aux parois 25, de façon à recevoir et isoler les deux autres bornes 13.The partitions 27, as well as the partition extension 21, are connected to a transverse wall 32 from which extend divided partitions 33 similar to partitions 23 so as to form two other terminal zones A delimited, at the part lower, by bottom walls 34 perpendicular to walls 32 and 33 and similar to walls 25, so as to receive and isolate the other two terminals 13.

Deux zones de contact C sont délimitées vers la partie inférieure de la structure entre les parois 22 et 32. A leur partie supérieure, ces zones de contact C sont délimitées par les parties correspondantes du fond 28 et, pour l'une d'elles, par une paroi 36 s'étendant vers le centre à partir de la cloison 22 et environ à mi-hauteur de celle-ci, et pour l'autre, par une paroi 37 plus longue s'étendant environ à la même hauteur que la paroi 36, de l'autre côté de la cloison médiane 21.Two contact zones C are delimited towards the lower part of the structure between the walls 22 and 32. At their upper part, these contact zones C are delimited by the corresponding parts of the bottom 28 and, for one of them, by a wall 36 extending towards the center starting from the partition 22 and approximately at mid-height thereof, and for the other, by a longer wall 37 extending approximately at the same height as the wall 36, on the other side of the central partition 21.

La cloison 21, au niveau des zones de contact C, présente une large échancrure 38, destinée au passage de la partie centrale du porte-contacts mobile, la cloison médiane 21 s'épaississant au-delà de l'échancrure 38 en une surépaisseur 39 formant un logement 40 pour le vissage d'une vis autotaraudeuse destinée à la fixation d'une pièce auxi­liaire. Vers les coins latéraux inférieurs de la paroi 26, et en alignement avec l'échancrure 38, se trouvent deux portées en forme de demi-cercle 41, destinées à recevoir les tourillons de pivotement de la pièce porte-contacts mobile, les deux portées 41 étant réunies par une nervure de rigi­dification transversale 42.The partition 21, at the contact areas C, has a wide notch 38, intended for the passage of the central part of the movable contact carrier, the central partition 21 thickening beyond the notch 38 in an extra thickness 39 forming a housing 40 for the screwing of a self-tapping screw intended for fixing an auxiliary part. Towards the lower lateral corners of the wall 26, and in alignment with the notch 38, there are two bearing surfaces in the form of a semicircle 41, intended to receive the pivot pins of the movable contact-carrying part, the two bearing surfaces 41 being joined by a transverse stiffening rib 42.

L'une des zones de contact C présente encore, à peu près dans le prolongement du fond 28, une cloison 43 dont la dimension latérale est bien inférieure à celle du fond 28 mais qui se prolonge par un retour 44 de sorte que subsiste, entre la cloison 43, le retour 44 et un prolongement de la portée 41, un passage 45 pour le levier de percussion du porte-contact mobile. Entre le retour 44 et la paroi 36, subsiste une échancrure 46.One of the contact zones C also has, roughly in the extension of the bottom 28, a partition 43 whose lateral dimension is much smaller than that of the bottom 28 but which is extended by a return 44 so that remains between the partition 43, the return 44 and an extension of the range 41, a passage 45 for the percussion lever of the movable contact carrier. Between the return 44 and the wall 36, there remains a notch 46.

A la partie inférieure, les deux zones de contact C se trouvent délimitées, au regard des parois 36 et 37, par une paroi transversale inférieure 47 se raccordant, en son milieu, à la cloison 21 et s'arrêtant un peu avant l'emplacement du logement de vis 40. Vers l'extrémité de la pièce de structure 20, la paroi 47 présente, au niveau de chacun des deux logements formant les zones de contact C, un prolongement 48 ayant une section en forme de bec et se situant au-dessous et à un certaine distance des parois 25 des zones de bornes A des bornes 13.At the lower part, the two contact zones C are delimited, with respect to the walls 36 and 37, by a lower transverse wall 47 connecting, in its middle, to the partition 21 and stopping a little before the location of the screw housing 40. Towards the end of the structural part 20, the wall 47 has, at each of the two housings forming the contact zones C, an extension 48 having a section in the shape of a beak and located at the below and at a certain distance from the walls 25 of the terminal areas A of the terminals 13.

Au-dessus de l'échancrure 46 entre les parois 36 et 44, et à une assez grande distance, c'est-à-dire au niveau de la partie supérieure, en cet endroit, de la cloison médiane 21, s'étend'une cloison transversale 49 parallèle aux cloisons 36, 43 et 44, cette cloison 49 se poursuivant vers le haut par une cloison 50 se terminant presque au sommet de la cloison médiane 21, cette cloison 50 étant écartée d'une certaine distance de la partie de la cloison transversale 26 qui lui fait face. Les cloisons 49 et 50, perpendiculaires entre elles, se relient à une cloison latérale 51 présentant une fente 52 dans laquelle peut être introduite, et retenue élastiquement, une patte de fixation d'un relais.Above the notch 46 between the walls 36 and 44, and at a fairly large distance, that is to say at the level of the upper part, in this place, of the central partition 21, extends' a transverse partition 49 parallel to the partitions 36, 43 and 44, this partition 49 continuing upwards by a partition 50 ending almost at the top of the central partition 21, this partition 50 being spaced a certain distance from the part of the transverse partition 26 which faces it. The partitions 49 and 50, perpendicular to each other, connect to a lateral partition 51 having a slot 52 into which can be inserted, and resiliently retained, a fixing lug of a relay.

La face extérieure de la cloison 51 présente avan­tageusement plusieurs bossages ou tétons, à savoir un grand bossage 53 autour duquel peut s'enrouler un ressort en épin­gle dont une des branches vient s'immobiliser entre des tétons de réglage de ressort 54 et dont l'autre extrémité va venir s appuyer sur un prolongement latéral d'une pièce solidaire du plongeur de bobine de disjonction pour rappeler le plongeur en arrière.The outer face of the partition 51 advantageously has several bosses or nipples, namely a large boss 53 around which a pin spring can be wound, one of the branches of which comes to rest between spring adjustment pins 54 and the other end of which will come to bear on a lateral extension of a part integral with the disjunction coil plunger to recall the plunger back.

La zone D située, d'un côté de la cloison médiane 21, entre les cloisons 22 et 26, d'une part, 36, 43, 44 et 49, d'autre part, forme ainsi la zone de déclenchement de dis­jonction électromagnétique destinée à recevoir notamment la bobine de disjonction avec son noyau plongeur et son percu­teur.Zone D situated, on one side of the central partition 21, between the partitions 22 and 26, on the one hand, 36, 43, 44 and 49, on the other hand, thus forms the electromagnetic tripping triggering zone intended to receive in particular the disjunction coil with its plunger core and its striker.

La zone E située au-dessus de la cloison 49 et délimitée d'un côté par la cloison 51, et, du côté de la zone de mesure B, par la cloison 50, forme une autre zone de moyen de déclenchement de mécanisme recevant le relais de déclenchement différentiel.Zone E situated above the partition 49 and delimited on one side by the partition 51, and, on the side of the measurement area B, by the partition 50, forms another zone of mechanism triggering means receiving the differential trip relay.

La zone F située entre les cloisons 50 et 26, d'un côté de la cloison médiane 21, et en communication, à sa partie inférieure, avec la zone D, forme une zone de déclenchement de disjonction thermique destinée à recevoir une bilame.The zone F situated between the partitions 50 and 26, on one side of the central partition 21, and in communication, at its lower part, with the zone D, forms a zone for triggering thermal disjunction intended to receive a bimetallic strip.

Une zone de test G est située au-dessus de la zone de mesure B et est destinée à recevoir un ensemble de test.A test area G is located above the measurement area B and is intended to receive a test set.

Enfin, la zone de mécanisme H s'étend, de l'autre côté de la cloison médiane 21 par rapport aux zones d'et F, et est délimitée par la cloison 21, la cloison 37 et, du côté de la zone de mesure, par la partie correspondante de la cloison transversale 26.Finally, the mechanism zone H extends, on the other side of the central partition 21 with respect to the zones of and F, and is delimited by the partition 21, the partition 37 and, on the side of the measurement zone , by the corresponding part of the transverse partition 26.

Dans cette zone de mécanisme H, la cloison médiane 21 présente, à sa partie supérieure, et de l'autre côté de la zone F, un axe 58 destiné à recevoir l'organe de manoeuvre pivotant avec sa manette. Au-dessous de l'axe de manette 58 se trouve un axe de pivotement 59 sur lequel pivotera l'extrémité supérieure du levier déclencheur de mécanisme. Juste au-dessus d'un passage 60 faisant communiquer la zone de mécanisme H avec la zone de contact C sous-jacente, la cloison 21 présente un axe 61 sur lequel sera monté, de façon pivotante, le cliquet de mécanisme. Au-dessus de la cloison 37, la paroi 21 présente, d'une part, un axe 62 de pivotement d'un levier de déclenchement par relais et un axe 63 sur lequel sera montée une pièce pivotante intermédiaire de déclenchement coopérant avec le levier précité.In this mechanism zone H, the central partition 21 has, at its upper part, and on the other side of the zone F, an axis 58 intended to receive the pivoting operating member with its lever. Below the lever axis 58 is a pivot axis 59 on which the upper end of the mechanism trigger lever will pivot. Just above a passage 60 communicating the mechanism zone H with the underlying contact zone C, the partition 21 has an axis 61 on which will be pivotally mounted the mechanism pawl. Above the partition 37, the wall 21 has, on the one hand, an axis 62 of pivoting of a relay release lever and an axis 63 on which will be mounted an intermediate pivoting release part cooperating with the aforementioned lever.

Un certain nombre de passages sont prévus dans la cloison médiane 21, à savoir un passage 64 long et s' étendant vers le bas, faisant communiquer la zone de mécanisme H avec la zone de disjonction thermique F.A number of passages are provided in the central partition 21, namely a passage 64 long and extending downwards, making the mechanism zone H communicate with the thermal disjunction zone F.

Au-dessus de la cloison 37 et sous les axes 62 et 63 se trouve pratiqué un passage 65 destiné à mettre en communica­tion la zone de disjonction électromagnétique d'avec la zone de mécanisme H.Above the partition 37 and under the axes 62 and 63 there is a passage 65 intended to put the electromagnetic disjunction zone into communication with the mechanism H zone.

Enfin, au niveau de l'axe 58 de l'organe de manoeuvre, la cloison 21 présente divers reliefs concentriques 67 destinés à recevoir un ressort de rappel d'organe de manoeuvre .Finally, at the axis 58 of the operating member, the partition 21 has various concentric reliefs 67 intended to receive a return spring for the operating member.

La pièce de structure 20 coopérera avec une pièce auxi­lilaire réalisée, soit d'un seul tenant, soit en deux par­ties séparées. Cette pièce auxiliaire 70 présente d'une part, un flasque 71 destiné à venir clôturer latéralement la zone de mécanisme H, ce flasque présentant à sa partie supérieure une fente 72 analogue à la fente 52 pour recevoir l'autre patte du relais et présentant également un certain nombre de portées qui viendront s'aligner avec les axes 58, 62 et 63. Enfin, ce flasque 71 présente, vers sa partie inférieure, un retour 73 se raccordant selon un arrondi au reste du flasque de façon à venir compléter le palier 41 situé du côté de la zone de mécanisme H.The structural part 20 will cooperate with an auxiliary part produced, either in one piece, or in two separate parts. This auxiliary part 70 has on the one hand, a flange 71 intended to laterally close the mechanism zone H, this flange having at its upper part a slot 72 similar to the slot 52 for receiving the other tab of the relay and also having a certain number of spans which will align with the axes 58, 62 and 63. Finally, this flange 71 has, towards its lower part, a return 73 connecting in a rounded shape to the rest of the flange so as to complete the bearing 41 located on the side of the mechanism zone H.

La pièce 70 présente, par ailleurs, une partie inférieure 74 perpendiculaire au flasque 71 et présentant un passage central dans lequel pourra passer la vis 75 assurant l'assemblage entre la pièce auxiliaire 70 et la pièce de structure 20. Cette partie 74 présente deux renfoncements pour les ressorts de rappel des contacts mobiles et se pour­suit, à l'opposé du flasque 71, par un retour 76 dont un prolongement 77 vient compléter le second palier 41.The part 70 has, moreover, a lower part 74 perpendicular to the flange 71 and having a central passage through which the screw 75 can pass, ensuring the assembly between the auxiliary part 70 and the structural part 20. This part 74 has two recesses for the return springs of the movable contacts and continues, opposite the flange 71, by a return 76, an extension 77 of which completes the second bearing 41.

Dans l'exemple représenté et décrit, les volumes respectifs des différentes zones sont à peu près dans les proportions suivantes, par rapport au volume total interne disponible à l'intérieur du boîtier 1, 2 :
zone de mesure B      22%
zones de contact C      30%(15 % chacune)
zone de mécanisme H      10% ensemble des zones de déclenchement électromagnétique et thermiques D, F      10%
zone de déclenchement de relais E      8%
zone de test G      4%
zones de borne A,      4% chacune, soit 16%In the example shown and described, the respective volumes of the different zones are roughly in the following proportions, relative to the total internal volume available inside the housing 1, 2:
measurement area B 22%
contact areas C 30% (15% each)
mechanism zone H 10% all electromagnetic and thermal trigger zones D, F 10%
relay trigger zone E 8%
test area G 4%
terminal A zones, 4% each, or 16%

Les zones en question sont bien isolées les unes par rapport aux autres, la zone de mesure B étant éloignée des zones de contact et des zones magnétothermiques, la zone de relais E, également sensible, étant également éloignée des zones de contact.The zones in question are well insulated from one another, the measurement zone B being distant from the contact zones and the magnetothermal zones, the relay zone E, also sensitive, being also distant from the contact zones.

Lorsque les différents organes et pièces sont montés sur la pièce de structure 20, l;appareil, dépouillé de son boîtier 1, 2, présente l'aspect représenté sur la figure 5.When the various members and parts are mounted on the structural part 20, the apparatus, stripped of its housing 1, 2, has the appearance shown in FIG. 5.

Les bornes à cage 12, 13, avec leurs vis 14, sont montées dans les logements formant les quatre zones de borne A.The cage terminals 12, 13, with their screws 14, are mounted in the housings forming the four terminal areas A.

Le tore de mesure 15 est inséré dans la zone de mesure B de forme cylindrique, autour du fût 30, et les conducteurs 16, en provenance des deux bornes 13 respectives, sont respectivement enroulés autour du tore 15 en passant cen­tralement à l'intérieur du fût 30, de part et d'autre d'une cloison médiane de celui-ci, et à l'extérieur par-dessus les cloisons 27. L'un des conducteurs 16 se raccorde alors au prolongement 80 de la bobine électromagnétique 81 avec son noyau plongeur 82 et son percuteur 83, la bobine 81 étant enroulée en relation avec une armature fixe ferromagnétique et conductrice 84 en forme de cage contenant la bobine 81 et dont un bras, s'étendant dans la zone F, porte à son extrémité supérieure 85 la bilame 86 dont la position peut être réglée par l'intermédiaire d'une vis de réglage 87 portée par une autre extrémité 88, en regard, d'un second bras de l'armature. A son extrémité arrière, le plongeur 82 présente une pièce 89 dans laquelle peut venir en prise un ressort (non représenté) de rappel de plongeur et qui, d'autre part, présente une partie en forme de rampe destinée à coopérer avec le cliquet pour le déclenchement du mécanisme de serrure.The measuring torus 15 is inserted in the measuring zone B of cylindrical shape, around the barrel 30, and the conductors 16, coming from the two respective terminals 13, are respectively wound around the torus 15 passing centrally inside the barrel 30, on either side of a central partition thereof, and on the outside over the partitions 27. One of the conductors 16 is then connected to the extension 80 of the electromagnetic coil 81 with its plunger core 82 and its striker 83, the coil 81 being wound in relation to a fixed ferromagnetic and conductive armature 84 in the form of a cage containing the coil 81 and one arm of which, extending in zone F, carries at its upper end 85 bimetallic strip 86 whose position can be adjusted by means of an adjustment screw 87 carried by another end 88, opposite, of a second arm of the frame. At its rear end, the plunger 82 has a part 89 in which a plunger return spring (not shown) can engage and which, on the other hand, has a ramp-shaped part intended to cooperate with the pawl for the triggering of the lock mechanism.

De façon avantageuse, l'ensemble composé par l'armature 84, la bobine 81, son noyau plongeur 82 avec le percuteur 83 ainsi que la bilame 86, est introduit latéralement sans dif­ficulté dans la pièce de structure 20, c'est-à-dire dans les logements d'et F qui communiquent entre eux.Advantageously, the assembly composed of the armature 84, the coil 81, its plunger core 82 with the striker 83 as well as the bimetallic strip 86, is introduced laterally without difficulty into the structural part 20, that is to say say in the housings of and F which communicate with each other.

Le porte-contacts pivotant 90 est monté, par ses tourillons 91, dans les portées 41 complétées par les pro­longements respectifs 73 et 77 et porte, d'une façon en soi connue, les contacts mobiles 92 normalement écartés des con­tacts fixes 93, formés dans des lames 94, par de puissants ressorts de rappel 95 prenant appui dans les renfoncements prévus à cet effet dans la partie 74 de la pièce auxiliaire 70. L'agencement des contacts mobiles 92 dans le porte-­contacts 90 est, d'une façon connue, tel que les ressorts 95 puissent aussi bien assurer la force nécessaire pour l'ouverture des contacts que la force d'appui des contacts mobiles 92 contre les contacts fixes 93 lorsqu'ils sont en position de fermeture. L'un des contacts mobiles 92 est relié, par une tresse conductrice 96, à celui des conduc­teurs 16 qui n'aboutit pas à la bobine de disjonction 81, l'autre contact mobile 92 étant relié, également par une tresse 97, à l'extrémité inférieure de la bilame 86 complétant ainsi le circuit.The pivoting contact carrier 90 is mounted, by its pins 91, in the bearings 41 supplemented by the respective extensions 73 and 77 and carries, in a manner known per se, the movable contacts 92 normally spaced from the fixed contacts 93, formed in blades 94, by powerful return springs 95 bearing in the recesses provided for this purpose in the part 74 of the auxiliary part 70. The arrangement of the movable contacts 92 in the contact carrier 90 is, in a known manner , such that the springs 95 can provide both the force necessary to open the contacts and the bearing force of the movable contacts 92 against the fixed contacts 93 when they are in the closed position. One of the movable contacts 92 is connected, by a conductive braid 96, to that of the conductors 16 which does not lead to the tripping coil 81, the other movable contact 92 being connected, also by a braid 97, to the 'lower end of bimetallic strip 86 thus completing the circuit.

Le dispositif étant ainsi monté, un bras 98 du porte-­contacts 90 traverse le passage 45 et se trouve donc, lorsque les contacts sont en position de fermeture, dans la trajectoire du percuteur 83. En fait, le bras 98, en posi­tion de contact ouvert, pénètre légèrement dans la zone de mesure B par le biais d'un passage 66 pratiqué dans la paroi 26 pour venir repousser une lame coudée de contact de test.The device being thus mounted, an arm 98 of the contact carrier 90 passes through the passage 45 and is therefore, when the contacts are in the closed position, in the path of the striker 83. In fact, the arm 98, in the contact position open, slightly enters the area of measure B by means of a passage 66 made in the wall 26 to push back a bent test contact blade.

On voit, par ailleurs, que les chambres de coupure d'arc 99 usuelles ont trouvé place à 1 une des extrémités des zones de contact C, au-dessus des parties correpondantes de la paroi 47.It can be seen, moreover, that the usual arc-breaking chambers 99 have found a place at one of the ends of the contact zones C, above the corresponding parts of the wall 47.

Le relais 100 d'interrupteur différentiel est logé dans sa zone E avec sa tige de relais orientée vers le bas. Il est maintenu en place par ses pattes latérales 101 s'encliquetant élastiquement dans les fentes 52, respective­ment 72.The differential switch relay 100 is housed in its zone E with its relay rod facing downwards. It is held in place by its lateral tabs 101 which snap into place in the slots 52 and 72 respectively.

Dans la zone de test G, la résistance de test 102 et le circuit imprimé de test 103 sont reçus dans leurs réceptacles respectifs pratiqués dans une pièce 104 dont le détail ne sera pas décrit, ladite pièce 104 étant clipée par deux pattes élastiques 105 dans des trous 68 pratiqués dans les parois 27, la pièce 104 étant ainsi superposée à la zone de mesure B. Le bouton de test 107 émerge au-dessus du som­met 8 du demi-boîtier 1 par un trou prévu à cet effet. Ce bouton permet d'ouvrir et de fermer un contact entre une lame coudée 106 et une extrémité de la résistance 102, l'autre branche de la lame 106, après un retour, se trouvant au niveau du bras 98 du porte-contact mobile 90 et dans la fin de sa trajectoire. Le circuit de test étant d'un prin­cipe connu, il ne sera pas décrit davantageIn the test zone G, the test resistor 102 and the test printed circuit 103 are received in their respective receptacles made in a part 104, the details of which will not be described, said part 104 being clipped by two elastic tabs 105 in holes 68 made in the walls 27, the part 104 thus being superimposed on the measurement area B. The test button 107 emerges above the top 8 of the half-housing 1 through a hole provided for this purpose. This button opens and closes a contact between a bent blade 106 and one end of the resistor 102, the other branch of the blade 106, after a return, being located at the arm 98 of the movable contact carrier 90 and at the end of its trajectory. The test circuit being of a known principle, it will not be described further

Le mécanisme d'actionnement et de serrure est, par exemple, du type de celui décrit dans la demande de brevet européen Ep-A-0. 143. 682. Sa fonction, en soi connue, est de permettre d'ouvrir ou de fermer manuellement les contacts en faisant basculer dans un sens ou dans un autre le porte-­contacts mobile 90, de maintenir le porte-contacts en posi­tion basculée de contact par une serrure à genouillère et d'autoriser, en cas de déclenchement, la cassure de la genouillère pour permettre aux puissants ressorts 95 de décoller les contacts mobiles 92 loin des contacts fixes 93.The actuation and lock mechanism is, for example, of the type described in European patent application Ep-A-0. 143. 682. Its function, known per se, is to allow the contacts to be opened or closed manually by tilting the movable contact carrier 90 in one direction or another, to maintain the contact carrier in the tilted position of contact by a toggle lock and to authorize, in the event of tripping, the breaking of the toggle to allow the powerful springs 95 to take off the movable contacts 92 away from the fixed contacts 93.

Ce mécanisme, dont le fonctionnement ne sera pas décrit en détail, comporte un organe de manoeuvre 110 pivotant autour de l'axe 58 et rappelé normalement en position correspondant à 1 ouverture des contacts par un ressort de rappel monté dans les reliefs 67, ledit organe de manoeuvre présentant une manette d'actionnement 111. Par un axe excentré par rapport à l'axe 58, la manette 111 est articulée à une bielle 112 elle-même articulée, à son extrémité inférieure, à l'extrémité supérieure d'une biel­lette 113. L'extrémité inférieure de celle-ci est articulée au porte-contacts mobile 90 en un emplacement excentré par rapport à l'axe des tourillons de celle-ci. L'axe 114 d'articulation entre la bielle 112 et la biellette 113 se prolonge latéralement pour pénétrer dans une rainure oblongue 115 située à l'extrémité d'un levier déclencheur 116 articulé par son extrémité supérieure à l'axe 59. A sa partie inférieure, au-delà de la rainure 115, le levier déclencheur 116 se termine par un bec 117 normalement empêché de s'échapper par la présence du bec complémentaire 118 d'un cliquet 119 articulé autour de l'axe 61 et normale­ment rappelé en position d'encliquetage, c'est-à-dire en sens horaire sur la figure 6, par un ressort de rappel de cliquet (non représenté). Ce cliquet présente, outre son bec 118, un bras allongé 120 se terminant par deux doigts transversaux dont l'un traverse le passage 65 pour coopérer avec la rampe que forme la pièce de plongeur 89, et l'autre va coopérer avec des moyens de déclenchement par le relais 100. Le cliquet 119 présente également un bras plus court 121 se terminant par un doigt transversal qui traverse le passage 64 pour coopérer avec la bilame 86.This mechanism, the operation of which will not be described in detail, comprises an operating member 110 pivoting about the axis 58 and normally returned to the position corresponding to 1 opening of the contacts by a return spring mounted in the reliefs 67, said operating member having an actuating handle 111. By an axis eccentric relative to the axis 58, the lever 111 is articulated to a connecting rod 112 which is itself articulated, at its lower end, to the upper end of a connecting rod 113. The lower end of the latter is articulated to the movable contact carrier 90 in an eccentric location relative to the axis of the pins thereof. The axis 114 of articulation between the connecting rod 112 and the connecting rod 113 extends laterally to penetrate an oblong groove 115 situated at the end of a trigger lever 116 articulated by its upper end to the axis 59. At its part lower, beyond the groove 115, the trigger lever 116 ends with a spout 117 normally prevented from escaping by the presence of the complementary spout 118 of a pawl 119 articulated around the axis 61 and normally returned to position latching, that is to say clockwise in Figure 6, by a pawl return spring (not shown). This pawl has, in addition to its spout 118, an elongated arm 120 ending in two transverse fingers, one of which crosses the passage 65 to cooperate with the ramp formed by the plunger part 89, and the other will cooperate with means of tripping by the relay 100. The pawl 119 also has a shorter arm 121 ending in a transverse finger which crosses the passage 64 to cooperate with the bimetallic strip 86.

Si la bobine de disjonction 81 se trouve excitée, le plongeur 82 est déplacé brutalement vers la gauche (figure 9) et son percuteur 83 vient repousser violemment le bras 98 du porte-contacts mobile 90 pour provoquer son mouvement d'ouverture et assurer l'arrachage des contacts mobiles 92 et leur séparation d'avec les contacts fixes 93. Simultanément, la pièce 89 de plongeur vient repousser le doigt du grand bras 120 du cliquet 119, assurant le bascule­ment du cliquet et la libération des becs respectifs 117, 118 et donc la cassure de la genouillère, autorisant le bas­culement du porte-contacts 90 vers sa position d'ouverture.If the disjunction coil 81 is excited, the plunger 82 is suddenly moved to the left (Figure 9) and its striker 83 violently pushes the arm 98 of the movable contact carrier 90 to cause its opening movement and ensure the removal of the movable contacts 92 and their separation from the fixed contacts 93. Simultaneously, the plunger part 89 pushes the finger of the large arm 120 of the pawl 119, ensuring the tilting of the pawl and the release of the respective spouts 117, 118 and therefore the breaking of the toggle joint, authorizing the tilting of the contact carrier 90 towards its open position.

De même la déformation de la bilame 86 sous l'effet d'une surintensité provoque une poussée de la bilame sur le doigt du bras court 121 du cliquet 119, de sorte que le cli­quet bascule, faisant casser la genouillère, et que les res­sorts 95 repoussent les contacts mobiles 92 et le porte­contacts 90 en position d'ouverture éloignée des contacts fixes 93.Similarly, the deformation of the bimetallic strip 86 under the effect of an overcurrent causes a thrust of the bimetallic strip on the finger of the short arm 121 of the pawl 119, so that the pawl rocks, causing the toggle to break, and the springs 95 push the movable contacts 92 and the contact carrier 90 into the open position away from the fixed contacts 93.

En cas d'actionnement par le relais 100, la tige de celui-ci, qui se déplace alors verticalement vers le bas, vient basculer un levier de déclenchement et de réarmement de relais 122 pivotant sur l'axe 62 et rappelé normalement en sens anti-horaire (figure 6) par un ressort de rappel. Ce levier 122 présente un court bras perpendiculaire 123 se terminant par un bec d'accrochage qui coopère avec un bec d'accrochage (non vu) d'une pièce pivotante intermédiaire de déclenchement 124 rappelée normalement en sens horaire (figure 6) autour de son axe 63 par un ressort convenable. Les becs ayant été dégagés l'un de l'autre par le bascule­ment du levier 122 sous l'effet de la descente de la tige du relais 100, la pièce 124 tourne en sens horaire (figure 6) et repousse le doigt correspondant terminant le long bras 120 du cliquet 119, assurant également la cassure de la genouillère et l'ouverture des contacts. La pièce 124 présente avantageusement un long bras 125 qui assure sa rem­ise en place lors du mouvement du mécanisme qui suit la cas­sure de la genouillère et qui est provoqué par l'action du ressort de rappel de l'organe de manoeuvre pivotant 110, mouvement qui ramène l'ensemble du mécanisme à sa position initiale de repos dans laquelle les contacts sont séparés, position représentée sur les figures 6 et 9.In the event of actuation by the relay 100, the rod of the latter, which then moves vertically downwards, switches a trigger and reset lever of the relay 122 pivoting on the axis 62 and normally returned in the anti-direction - schedule (Figure 6) by a return spring. This lever 122 has a short perpendicular arm 123 ending in a hooking beak which cooperates with a hooking beak (not seen) of an intermediate pivoting trigger piece 124 normally called clockwise (FIG. 6) around its axis 63 by a suitable spring. The spouts having been released from one another by the tilting of the lever 122 under the effect of the descent of the rod of the relay 100, the part 124 rotates clockwise (FIG. 6) and pushes the corresponding finger ending the long arm 120 of the pawl 119, also ensuring the breaking of the toggle joint and the opening of the contacts. The piece 124 advantageously has a long arm 125 which ensures its repositioning during the movement of the mechanism which follows the breaking of the toggle joint and which is caused by the action of the return spring of the pivoting operating member 110, movement which returns the entire mechanism to its initial rest position in which the contacts are separated, position shown in FIGS. 6 and 9.

En se référant plus particulièrement à la figure 1, on voit que l'invention permet non seulement une répartion optimale des volumes disponibles mais également un montage particulièrement rationnel des différents constituants du dispositif.Referring more particularly to FIG. 1, it can be seen that the invention allows not only a distribution optimal available volumes but also a particularly rational assembly of the various components of the device.

Ainsi, on peut réaliser séparément l'ensemble magnétothermique avec la bobine 81 et la bilame 86, l'ensemble de test avec son support 104 ayant reçu tous les autres constituants, et un ensemble de mécanisme comprenant le mécanisme de genouillère et le porte-contacts mobile 90 avec ses contacts 92, de même que deux ensembles formés cha­cun par une borne 12, une lame 94 représentant le contact fixe 93 et la chambre de coupure d'arc 99.Thus, the magnetothermal assembly can be produced separately with the coil 81 and the bimetallic strip 86, the test assembly with its support 104 having received all the other constituents, and a mechanism assembly comprising the toggle mechanism and the contact carrier. mobile 90 with its contacts 92, as well as two assemblies each formed by a terminal 12, a blade 94 representing the fixed contact 93 and the arc breaking chamber 99.

Ces différents ensembles, de même que le relais 100, viennent se disposer par emboîtement dans leurs zones respectives. Il suffit ensuite de venir mettre en place la pièce auxiliaire 70 pour que le mécanisme se trouve monté dans sa position définitive.These different assemblies, as well as the relay 100, are arranged by interlocking in their respective zones. Then just come to set up the auxiliary part 70 so that the mechanism is mounted in its final position.

En dehors de ces opérations de montage simples, les seules opérations à réaliser sont, d'une part, l'enroulement des conducteurs 16, une fois le tore 15 mis en place et avant clipsage de l'ensemble de test, le soudage de l'une des extrémités des deux conducteurs 16 aux tresses respec­tives, le soudage de l'un de ces conducteurs 16 à l'extrémité d'une lame conductrice 126 se dirigeant vers l'une des chambres de coupure d'arc, la liaison des conduc­teurs issus du relais aux conducteurs provenant du tore et la soudure de l'une des deux extrémités de la résistance de test 102 aux conducteurs adéquats.Apart from these simple assembly operations, the only operations to be carried out are, on the one hand, the winding of the conductors 16, once the torus 15 is in place and before the test assembly is clipped, the welding of the one of the ends of the two conductors 16 with the respective braids, the welding of one of these conductors 16 at the end of a conductive strip 126 pointing towards one of the arc-breaking chambers, the connection of the conductors from the relay to the conductors from the toroid and the soldering of one of the two ends of the test resistor 102 to the appropriate conductors.

Les différents éléments ainsi mis en place sont ferme­ment maintenus par la pièce de structure centrale, aucune pièce et aucun conducteur n'étant en fait flottant. Il suf­fit alors, sans aucune précaution particulière, de venir habiller l'ensemble tel qu'on le voit sur la figure 5 à l'aide des deux demi-boîtiers 1, 2 et le dispositif est prêtThe various elements thus put in place are firmly held by the central structural part, no part and no conductor being in fact floating. It then suffices, without any particular precaution, to dress the assembly as seen in FIG. 5 using the two half-housings 1, 2 and the device is ready
