Description

La présente invention concerne un support de maintien en position de conducteurs électriques d'un câble de cordon électrique pour une machine automatique destinée à travailler les conducteurs lors de la fabrication en grande série des cordons électriques, ce support présentant une forme générale de peigne comportant une plaque rectangulaire fixe disposée dans un plan vertical et creusée, à partir de sa face supérieure, d'une pluralité de rainures verticales parallèles, réparties sur toute la longueur de la plaque et dans chacune desquelles est introduit transversalement de haut en bas un conducteur venant reposer sur le fond de la rainure, lesdites rainures laissant subsister entre elles des zones formant des dents.The present invention relates to a support for holding in position electrical conductors of an electrical cord cable for an automatic machine intended to work the conductors during the mass production of electrical cords, this support having a general form of comb comprising a fixed rectangular plate arranged in a vertical plane and hollowed out, from its upper face, with a plurality of parallel vertical grooves, distributed over the entire length of the plate and in each of which is inserted transversely from top to bottom a conductor coming to rest on the bottom of the groove, said grooves leaving areas forming teeth between them.

Comme cela est bien connu, un cordon électrique destiné à équiper un appareil, par exemple du type électroménager, se compose d'un câble gainé de longueur donnée comprenant plusieurs conducteurs électriques multi-brins gainés, par exemple au nombre de trois (un conducteur de phase, un conducteur de neutre et un conducteur de terre), et dénudés en leurs deux extrémités respectives sur l'une desquelles est sertie une cosse de connexion électrique et sur l'autre est serti un insert commun sur lequel est moulé une fiche électrique.As is well known, an electrical cord intended to equip an appliance, for example of the household appliance type, consists of a sheathed cable of given length comprising several sheathed multi-strand electrical conductors, for example three in number (one conductor of phase, a neutral conductor and an earth conductor), and stripped at their two respective ends on one of which is crimped an electrical connection terminal and on the other is crimped a common insert on which is molded an electrical plug.

Dans la fabrication automatisée en grande série de ces cordons électriques, à partir de chaque câble non encore équipé des cosses et de l'insert, les opérations de dénudage des deux extrémités de chaque conducteur du câble et de sertissage tant de chaque cosse que de l'insert sont effectuées successivement sur différents postes de travail d'une même machine.In the automated mass production of these electrical cords, from each cable not yet fitted with lugs and the insert, the stripping operations of the two ends of each conductor of the cable and of crimping both of each terminal and of the 'insert are carried out successively on different workstations of the same machine.

Pour permettre une exécution précise de ces opérations de dénudage et de sertissage, les conducteurs électriques de chaque câble doivent être correctement maintenus en position vis-à-vis de l'outil de travail correspondant. C'est la raison pour laquelle la machine dite de travail des conducteurs de chaque câble est équipée en série d'un grand nombre de supports assurant chacun le maintien en position des conducteurs électriques de chaque câble, lesquels supports étant chacun du type exposé ci-dessus.To allow precise execution of these stripping and crimping operations, the electrical conductors of each cable must be correctly held in position vis-à-vis the corresponding work tool. This is the reason why the so-called machine for working the conductors of each cable is equipped in series with a large number of supports, each ensuring the holding in position of the electrical conductors of each cable, which supports being each of the type described above. above.

Cependant, de tels supports d'une même série sont actuellement adaptés pour une seule section donnée des conducteurs électriques à travailler, de sorte qu'en cas de changement de section des conducteurs, nécessité par la fabrication d'un nouveau cordon de calibre différent, on doit arrêter la machine de travail, démonter les supports précédemment utilisés, puis remonter sur la machine d'autres supports adaptés à la nouvelle section des conducteurs à travailler. Ces différentes opérations impliquent donc une durée d'intervention très longue, d'autant que la machine est équipée d'un grand nombre de supports (de l'ordre de 80), ce qui affecte notablement le rendement global de la ligne de fabrication des cordons électriques.However, such supports of the same series are currently adapted for a single given section of the electrical conductors to be worked, so that in the event of a change of section of the conductors, necessary by the manufacture of a new cord of different gauge, the work machine must be stopped, the supports previously used must be dismantled, then other supports adapted to the new section of the conductors to be worked must be reassembled on the machine. These different operations therefore imply a very long intervention time, especially since the machine is equipped with a large number of supports (of the order of 80), which notably affects the overall performance of the production line of the electrical cords.

L'invention a en particulier pour but de remédier à ces inconvénients et de réaliser un même support de maintien en position de conducteurs électriques pour une machine automatique de travail de câble d'un cordon électrique, qui puisse être utilisé pour différentes sections de conducteurs, donc sans nécessité d'être démonté de la machine lors d'un changement de section des conducteurs.The object of the invention is in particular to remedy these drawbacks and to produce the same support for holding in position electrical conductors for an automatic machine for working the cable of an electrical cord, which can be used for different sections of conductors, therefore without the need to be dismantled from the machine when the conductor section is changed.

Elle a également pour but d'assurer un maintien serré des conducteurs à travailler, et ce, quelle que soit la section des conducteurs utilisés.It also aims to ensure a tight hold of the conductors to work, and this, whatever the section of the conductors used.

Selon l'invention, un support de maintien en position de conducteurs électriques du type décrit précédemment, est plus particulièrement caractérisé en ce que chaque rainure de la plaque constituant un gabarit de support qui est imposé, dans une gamme donnée de sections de conducteur, pour la section maximale des conducteurs, la plaque rainurée présente une fente longitudinale qui est ménagée à partir de sa face supérieure, sur toute sa longueur, qui s'étend verticalement sur au moins toute la hauteur des dents de manière à former deux rangées identiques de dents et de rainures, et dans laquelle est disposé sensiblement sans jeu un coulisseau plat longitudinal qui présente une bordure supérieure formée d'une pluralité de dents attribuées chacune à une des rainures de la plaque, de largeurs respectives au plus égales à la largeur des dents de la plaque, et séparées par des échancrures ayant un fond situé au même niveau que le fond des rainures de la plaque, et qui est mobile horizontalement entre une position de repos dans laquelle chacune desdites dents est positionnée par rapport à la rainure correspondante de la plaque de manière à autoriser l'introduction du conducteur dans ladite rainure, et une position de serrage dans laquelle chacune desdites dents forme avec chacune des dents associées de la plaque, dans le fond de la rainure correspondante, une zone de serrage du conducteur, laquelle zone variant en fonction de la section du conducteur utilisé, dans la gamme donnée de sections de conducteur.According to the invention, a support for holding in position electrical conductors of the type described above, is more particularly characterized in that each groove of the plate constituting a support template which is imposed, in a given range of conductor sections, to the maximum section of the conductors, the grooved plate has a longitudinal slot which is formed from its upper face, over its entire length, which extends vertically over at least the entire height of the teeth so as to form two identical rows of teeth and grooves, and in which is disposed substantially without play a longitudinal flat slide which has an upper edge formed by a plurality of teeth each assigned to one of the grooves of the plate, of respective widths at most equal to the width of the teeth the plate, and separated by notches having a bottom situated at the same level as the bottom of the grooves of the plate e, and which is movable horizontally between a rest position in which each of said teeth is positioned relative to the corresponding groove of the plate so as to allow the introduction of the conductor into said groove, and a clamping position in which each of said teeth form with each of the associated teeth of the plate, in the bottom of the corresponding groove, a conductor clamping area, which area varying according to the section of the conductor used, in the given range of conductor sections.

Grâce au coulisseau mobile interposé entre les deux rangées parallèles de dents et de rainures de la plaque, on obtient ainsi un support qui est parfaitement adapté à maintenir en position serrée différentes sections de conducteurs à travailler, dans la gamme donnée des valeurs de section.Thanks to the movable slide interposed between the two parallel rows of teeth and grooves of the plate, a support is thus obtained which is perfectly adapted to maintain in tight position different sections of conductors to be worked, in the given range of section values.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre d'un mode particulier de réalisation pris à titre d'exemple non limitatif illustré aux dessins annexés dans lesquels :

  • les figures 5, 6 et 7 sont des vues identiques à la figure 4, montrant le support en position de serrage de trois conducteurs électriques de sections minimales (figure 5), de sections moyennes (figure 6) et de sections maximales (figure 7).
The characteristics and advantages of the invention will become apparent from the following description of a particular embodiment taken by way of nonlimiting example illustrated in the accompanying drawings in which:
  • Figure 1 is a perspective view, partially broken away, of a support according to the invention;
  • Figure 2 is a longitudinal sectional view of one of the two outer plates of the support of Figure 1;

  • Figures 5, 6 and 7 are views identical to Figure 4, showing the support in the clamping position of three electrical conductors with minimum sections (Figure 5), medium sections (Figure 6) and maximum sections (Figure 7) .

Dans ce qui suit, on décrira le support conforme à l'invention qui assure le maintien en position de conducteurs électriques gainés d'un câble de cordon électrique pour une machine automatique destinée à effectuer successivement sur les conducteurs diverses opérations, telles que notamment un dénudage des extrémités des conducteurs et un sertissage d'un organe de connexion sur l'extrémité dénudée des conducteurs, étant entendu qu'une telle machine est équipée en série d'un grand nombre de supports de maintien en position utilisés dans le cadre d'une fabrication en grande série de cordons électriques.In what follows, the support according to the invention will be described which ensures the maintenance in position of electrical conductors sheathed with an electric cord cable for an automatic machine intended to carry out successively on the conductors various operations, such as in particular stripping of the ends of the conductors and a crimping of a connection member on the stripped end of the conductors, it being understood that such a machine is equipped in series with a large number of supports for holding in position used in the context of a mass production of electrical cords.

Dans l'exemple de réalisation illustré à la figure 1, le support 1 conforme à l'invention présente une forme générale de peigne et comporte, dans un plan vertical, deux plaquettes rectangulaires identiques parallèles 3, formées par usinage dans une même plaque métallique 4, séparées l'une de l'autre par une fente longitudinale centrale 5 pratiquée dans la plaque, sur une certaine hauteur de cette dernière, et présentant chacune, d'une manière identique, une pluralité de rainures verticales parallèles 7, ouvertes vers le haut, au nombre de trois dans cet exemple, et réparties sur toute la longueur de la plaquette en délimitant entre elles quatre zones 9 en forme de dents, comme visible à la figure 2.In the embodiment illustrated in Figure 1, the support 1 according to the invention has a general form of comb and comprises, in a plane vertical, two identical parallel rectangular plates 3, formed by machining in the same metal plate 4, separated from each other by a central longitudinal slot 5 formed in the plate, over a certain height of the latter, and each having, in an identical manner, a plurality of parallel vertical grooves 7, open upwards, three in number in this example, and distributed over the entire length of the plate, delimiting between them four tooth-shaped zones 9, as visible in Figure 2.

Les trois rainures 7 conjuguées par paire des deux plaquettes 3 sont destinées respectivement à supporter transversalement, par leurs fonds respectifs 11 de forme arrondie, trois conducteurs électriques cylindriques, à savoir un conducteur de phase, un conducteur de neutre et un conducteur de terre. Les trois rainures 7 des deux plaquettes 3 sont par ailleurs dimensionnées de manière à constituer par paire un gabarit de support, désigné en 13 sur la figure 1, qui est imposé, dans une gamme ou plage donnée de valeurs de section de conducteur, par exemple de 0,75 mm² à 1,5 mm², pour la section maximale des conducteurs.The three grooves 7 conjugated in pairs of the two plates 3 are respectively intended to support transversely, by their respective bottoms 11 of rounded shape, three cylindrical electrical conductors, namely a phase conductor, a neutral conductor and an earth conductor. The three grooves 7 of the two plates 3 are also dimensioned so as to constitute in pairs a support template, designated at 13 in FIG. 1, which is imposed, within a given range or range of values of conductor cross-section, for example from 0.75 mm² to 1.5 mm², for the maximum cross-section of the conductors.

Dans la fente 5 de séparation des deux plaquettes rainurées et dentées 3, figure 1, est disposé sensiblement sans jeu, parallèlement aux plaquettes 3, un coulisseau plat rectangulaire mobile 15, réalisé en métal, et reposant longitudinalement sur le fond horizontal formant glissière 16 (figure 4) de ladite fente.In the slot 5 for separating the two grooved and toothed plates 3, FIG. 1, is arranged substantially without play, parallel to the plates 3, a movable rectangular flat slide 15, made of metal, and resting longitudinally on the horizontal bottom forming a slide 16 ( Figure 4) of said slot.

A titre de variante non illustrée, la fente 5 s'étend sur toute la hauteur de la plaque 4 de manière à former les deux plaquettes 3, lesquelles sont associées l'une à l'autre par une entretoise dont la partie supérieure constitue un guide pour le coulisseau 15.As a variant not illustrated, the slot 5 extends over the entire height of the plate 4 so as to form the two plates 3, which are associated with each other by a spacer, the upper part of which constitutes a guide for slide 15.

En référence aux figures 3 et 4, le coulisseau 15 présente une bordure supérieure 17 creusée d'une pluralité d'échancrures verticales parallèles 18, en l'occurrence au nombre de trois, de largeurs respectives légèrement supérieures à celle des rainures 7 des deux plaquettes 3, présentant chacune un fond plat 19 et délimitant entre elles quatre zones 20 en forme de dents, de hauteurs et de largeurs respectives inférieures à celles des dents 9 des deux plaquettes 3. Comme le montre la figure 4, le fond 19 de chacune des échancrures 18 du coulisseau 15 est situé au même niveau que le fond 11 des rainures appariées 7 des plaquettes 3.With reference to FIGS. 3 and 4, the slide 15 has an upper edge 17 hollowed out with a plurality of parallel vertical notches 18, in this case three in number, of respective widths slightly greater than that of the grooves 7 of the two plates. 3, each having a flat bottom 19 and delimiting between them four tooth-shaped zones 20, of respective heights and widths less than those of the teeth 9 of the two plates 3. As shown in FIG. 4, the bottom 19 of each of the notches 18 of the slide 15 is located at the same level as the bottom 11 of the paired grooves 7 of the plates 3.

Dans l'exemple représenté à la figure 4, le coulisseau 15 occupe, en l'absence des conducteurs, une position de repos dans laquelle une partie 20a de chacune de ses dents 20 est en saillie dans la paire de rainures correspondantes 7 des deux plaquettes 3 d'une manière telle que cette partie de dent 20a délimite avec les parties de dents appariées 9 des plaquettes qui lui font face, dans ladite paire de rainures correspondantes 7, un passage traversant 22 présentant une section sensiblement inférieure à la section minimale des conducteurs, dans la gamme donnée des sections de conducteur.In the example shown in FIG. 4, the slider 15 occupies, in the absence of the conductors, a rest position in which a part 20a of each of its teeth 20 projects into the pair of corresponding grooves 7 of the two plates 3 in such a way that this tooth part 20a delimits with the paired teeth parts 9 of the plates which face it, in said pair of corresponding grooves 7, a through passage 22 having a section substantially less than the minimum section of the conductors , in the given range of conductor cross-sections.

Le coulisseau 15 est maintenu dans cette position de repos, figure 4, au moyen d'un ressort spiralé 24 qui est interposé horizontalement entre une paroi latérale externe 25 du coulisseau 15 et une paroi parallèle d'appui 26 prévue dans une pièce auxiliaire métallique 28 qui est rapportée latéralement sur l'ensemble des deux plaquettes 3 au moyen d'une vis de fixation 30 venant s'engager dans un filetage pratiqué dans la base commune de la plaque métallique 4.The slider 15 is held in this rest position, FIG. 4, by means of a spiral spring 24 which is horizontally interposed between an external lateral wall 25 of the slider 15 and a parallel support wall 26 provided in a metallic auxiliary part 28 which is attached laterally to the assembly of the two plates 3 by means of a fixing screw 30 which engages in a thread made in the common base of the metal plate 4.

Comme on le voit sur la figure 4, la pièce auxiliaire 28 présente un évidement vertical 32 dans lequel débouche la paroi latérale 25 du coulisseau 15 et qui communique avec un logement horizontal 33 en forme de U dans lequel est maintenu en majeure partie le ressort 24, le fond de ce logement 33 constituant la paroi d'appui 26 du ressort 24.As can be seen in FIG. 4, the auxiliary part 28 has a vertical recess 32 into which the side wall 25 of the slide 15 opens and which communicates with a horizontal housing 33 in the form of a U in which the spring 24 is mainly held , the bottom of this housing 33 constituting the support wall 26 of the spring 24.

Le coulisseau 15, en position de repos représentée à la figure 4, est déplacé suivant le sens de la flèche F sous l'action d'une force de pression exercée par chaque conducteur, à l'encontre de la force du ressort 24, sur la partie en saillie 20a de la dent correspondante 20 du coulisseau lors de l'introduction de haut en bas, symbolisée par les flèches G, de chaque conducteur dans le passage traversant correspondant 22.The slide 15, in the rest position shown in FIG. 4, is moved in the direction of the arrow F under the action of a pressure force exerted by each conductor, against the force of the spring 24, on the projecting part 20a of the corresponding tooth 20 of the slide during the introduction from top to bottom, symbolized by the arrows G, of each conductor in the corresponding through passage 22.

Cette force de pression exercée par chaque conducteur lors de son introduction dans le passage traversant correspondant 22 provoque, par suite du déplacement du coulisseau 15, un élargissement dudit passage traversant, de sorte qu'en fin d'introduction de chaque conducteur, le coulisseau vient occuper une position de serrage dans laquelle chaque conducteur est maintenu serré, en fond de rainure correspondante 7, entre les deux dents respectives 9 et 20 des plaquettes 3 et du coulisseau 15, ces deux dents délimitant entre elles une zone de serrage qui varie en fonction de la section des conducteurs utilisés.This pressure force exerted by each conductor during its introduction into the corresponding through passage 22 causes, as a result of the displacement of the slide 15, a widening of said through passage, so that at the end of introduction of each conductor, the slide comes occupy a clamping position in which each conductor is held clamped, at the bottom of the corresponding groove 7, between the two respective teeth 9 and 20 of the plates 3 and of the slide 15, these two teeth delimiting between them a clamping zone which varies according to of the conductor section used.

Sur les figures 5 à 7, on a illustré trois positions de serrage que peut occuper le coulisseau 15 en fonction de trois sections différentes des conducteurs utilisés, dans la gamme donnée des sections de conducteur. La figure 5 représente le serrage de trois conducteurs 35 de sections respectives minimales dans des zones de serrage 36 définies chacune par les deux dents 9 et 20 des plaquettes 3 et du coulisseau 15, la figure 6 celui de trois conducteurs 37 de sections respectives moyennes dans des zones de serrage 38 plus larges, et la figure 7 celui de trois conducteurs 39 de sections respectives maximales dans des zones de serrage 40 correspondant quasiment aux rainures appariées 7 des deux plaquettes 3.In FIGS. 5 to 7, three clamping positions have been illustrated which the slide 15 can occupy as a function of three different sections of the conductors used, in the given range of conductor sections. FIG. 5 shows the clamping of three conductors 35 of minimum respective sections in zones clamping 36 each defined by the two teeth 9 and 20 of the plates 3 and of the slide 15, FIG. 6 that of three conductors 37 of medium respective sections in wider clamping zones 38, and FIG. 7 that of three conductors 39 of respective maximum sections in clamping zones 40 corresponding almost to the matched grooves 7 of the two plates 3.

Il convient de noter que, lors d'un changement de section des conducteurs, le coulisseau 15 est rappelé vers sa position de repos (figure 4) par le ressort 24.It should be noted that, when the conductor section changes, the slider 15 is returned to its rest position (FIG. 4) by the spring 24.

De préférence, chacune des deux dents 9 et 20, respectivement des plaquettes 3 et du coulisseau 15, servant à définir ensemble la zone de serrage de chaque conducteur, présente à sa partie supérieure un profil oblique tourné vers le haut permettant de ne pas blesser le conducteur électrique lors de son introduction par pression dans le passage traversant correspondant 22 défini pour la position de repos du coulisseau 15.Preferably, each of the two teeth 9 and 20, respectively of the plates 3 and of the slide 15, serving to define together the clamping zone of each conductor, has at its upper part an oblique profile turned upwards so as not to injure the electrical conductor when introduced by pressure into the corresponding through passage 22 defined for the rest position of the slide 15.

Pour parfaire le guidage du coulisseau 15 entre sa position de repos et sa position de serrage, celui-ci présente deux lumières de débattement 43 ménagées suivant un même axe horizontal et dans chacune desquelles est engagé sensiblement sans jeu un pion fixe formant guide 44 entretoisant les deux plaquettes 3.To perfect the guidance of the slide 15 between its rest position and its clamping position, the latter has two clearance slots 43 formed along the same horizontal axis and in each of which is engaged substantially a fixed pin forming a guide 44 bracing the two pads 3.
