Description

La présente invention concerne un appareil interrupteur à détection de mouvement ou de proximité, comprenant un organe sensible pour effectuer cette détection, ainsi qu'un corps définissant un logement pour un ensemble interrupteur commandé par l'organe sensible et relié à l'extérieur par un câble de liaison électrique, le logement étant fermé par un couvercle démontable.The present invention relates to a motion detection switch device or proximity, comprising a sensitive organ for carrying out this detection, as well that a body defining a housing for a switch assembly controlled by the sensitive organ and connected to the outside by an electrical connection cable, the housing being closed by a removable cover.

Les appareils interrupteurs de position ou de sécurité à usage industriel sont bien connus (par exemple produits XCK-J, voir catalogue Telemecanique "interrupteurs de position", avril 1999). Le câblage du bloc de contacts de tels appareils est difficile et les différents appareils d'une gamme nécessitent des boítiers différents quand on souhaite raccorder à ces boítiers des câbles de différents diamètres ou adjoindre à ces boítiers des entrées de câbles munies de filetages différents.Position or safety switches for industrial use are good known (for example XCK-J products, see Telemecanique catalog "switches position ", April 1999). Wiring the contact block of such devices is difficult and the different devices of a range require different cases when you would like to connect cables of different diameters to these boxes or add these boxes of cable entries provided with different threads.

Le document WO-99/27 551 montre un interrupteur de position dans lequel le corps et le couvercle présentent chacun une demi-collerette filetée pour recevoir un écrou de serrage d'un manchon d'étanchéité. Le serrage de l'écrou a pour effet de déformer ou repositionner le couvercle, ce qui altère les qualités d'étanchéité de l'appareil.WO-99/27 551 shows a position switch in which the body and the cover each have a threaded half-flange to receive a nut tightening a sealing sleeve. Tightening the nut has the effect of deform or reposition the cover, which impairs the sealing qualities of the device.

L'invention a pour but de faciliter le montage et le câblage, dans le corps de tels appareils, d'un bloc interrupteur doté d'éléments de connexion, en respectant une bonne étanchéité de l'ensemble, tout en permettant d'utiliser des câbles de différents diamètres ou des raccords de caractéristiques différentes sans modifier le corps.The invention aims to facilitate mounting and wiring in the body of such devices, of a switch block provided with connection elements, respecting a good sealing of the assembly, while allowing the use of cables different diameters or fittings of different characteristics without changing the body.

Selon l'invention, le raccord amovible passe-câble est introduit au moyen d'éléments d'emboítement, par un mouvement de glissement selon une direction sensiblement perpendiculaire à la paroi principale du couvercle, dans des formes de guidage et de maintien prévues dans le corps. Il est ainsi possible d'adjoindre à un même corps d'appareil des raccords différenciés par leur diamètre interne ou par leur type de filetage. According to the invention, the removable cable gland connector is introduced by means of interlocking elements, by a sliding movement in a direction substantially perpendicular to the main wall of the cover, in forms of guidance and support provided in the body. It is thus possible to add to a same body of fittings differentiated by their internal diameter or by their type of thread.

Les formes de guidage et de maintien du corps sont de préférence rectilignes et les éléments d'emboítement du raccord forment un cadre muni sur ses côtés de formes d'insertion complémentaires des formes de guidage et de maintien, le bloc interrupteur et le raccord étant introduits dans le corps de l'appareil dans une même direction. Le cadre est avantageusement symétrique, situé à l'extrémité du raccord et logé en partie dans le logement du bloc interrupteur et en partie dans des formes de guidage et de maintien prévues dans le couvercle.The forms of guiding and holding the body are preferably straight and the coupling fitting elements form a frame provided on its sides with shapes of complementary insertion of the guiding and holding forms, the block switch and fitting being introduced into the body of the device in a single direction. The frame is advantageously symmetrical, located at the end of the fitting and housed partly in the housing of the switch block and partly in forms guide and holding provided in the cover.

Le raccord porte un joint d'étanchéité extérieur et le couvercle est monté sur le corps au moyen d'éléments de pivotement, de préférence des crochets, prévus près d'une extrémité et présente à l'autre extrémité une vis de fixation au corps, les éléments de pivotement étant décalés par rapport au plan de la paroi principale du couvercle de manière à augmenter le couple de serrage du joint.The fitting carries an external seal and the cover is mounted on the body by means of pivoting elements, preferably hooks, provided near from one end and has at the other end a fixing screw to the body, the pivot elements being offset from the plane of the main wall of the cover so as to increase the tightening torque of the seal.

    • L'appareil interrupteur représenté sur les figures est un interrupteur de position, qui comprend un corps 10 et, à titre d'organe sensible au mouvement d'un objet, un ensemble de levier pivotant 11 fixé au corps près d'une première extrémité 10a de celui-ci. Le corps est de forme générale parallélépipédique et définit près de cette extrémité 10a un logement 11a pour recevoir une partie de l'ensemble 11; le corps définit aussi dans sa partie intermédiaire 10c un logement 12a pour recevoir, par introduction selon une direction Y, un bloc interrupteur amovible 12 qui est actionné par l'ensemble 11, le logement 12a étant normalement fermé par un couvercle 20. Le bloc interrupteur 12 présente des éléments de commutation mécaniques ou électroniques et il est relié à un organe ou circuit extérieur à l'appareil au moyen d'éléments de connexion 12b auxquels se raccordent des conducteurs rassemblés dans un câble C (voir figure 2) qui est maintenu par un raccord 30 lui-même fixé au corps 10 vers une seconde extrémité 10b de celui-ci. Le bloc 12 présente vers le haut (figures 1 et 2) une plaquette encliquetable 12c qui cache les plages de connexion après câblage. Le corps 10, le couvercle 20 et le raccord 30 sont en matière isolante ou métallique.The switch device shown in the figures is a position switch, which comprises a body 10 and, as an organ sensitive to the movement of an object, a pivoting lever assembly 11 fixed to the body near a first end 10a of this one. The body is of generally parallelepiped shape and defines near this end 10a a housing 11a for receiving part of the assembly 11; the body also defines in its intermediate part 10c a housing 12a for receiving, by introduction in a direction Y, a removable switch block 12 which is actuated by the assembly 11, the housing 12a being normally closed by a cover 20. The switch block 12 has mechanical switching elements or electronic and it is connected to an organ or circuit external to the device by means of connection elements 12b to which assembled conductors are connected in a cable C (see FIG. 2) which is held by a connector 30 itself fixed to the body 10 to a second end 10b thereof. Block 12 presents towards the top (Figures 1 and 2) a snap-on plate 12c which hides the areas of connection after wiring. The body 10, the cover 20 and the connector 30 are in insulating or metallic material.

    Le corps 10 de l'appareil présente des parois latérales 13 sensiblement planes et une paroi de fond 14 plane de plan P qui délimitent le logement 12a. A l'extrémité 10b, le corps 10 possède une paroi 15 de passage pour le câble C. La paroi 15 a un évidement semi-circulaire qui forme une demi-collerette 16 pour constituer un passage pour le câble C. Vers l'intérieur du corps par rapport à la collerette sont prévues des formes rectilignes de guidage et de maintien 17 du raccord, par exemple des rainures et/ou nervures dirigées perpendiculairement au plan P de la paroi de fond 14 (verticales sur les figures).The body 10 of the device has substantially flat side walls 13 and a flat bottom wall 14 of plane P which delimit the housing 12a. At the end 10b, the body 10 has a wall 15 for passage of the cable C. The wall 15 has a semi-circular recess which forms a half-flange 16 to form a passage for cable C. Towards the inside of the body with respect to the flange are provided with straight lines for guiding and holding the connector 17, by example of the grooves and / or ribs directed perpendicular to the plane P of the bottom wall 14 (vertical in the figures).

    Un couvercle 20 est fixé au corps pour fermer l'ouverture par laquelle s'introduit le bloc interrupteur 12. Il comprend une paroi principale de fermeture 21 qui est plane ou gauche, en s'étendant sensiblement parallèlement au plan P de la face arrière 14, pour recouvrir le logement 12a.A cover 20 is fixed to the body to close the opening through which the switch block 12. It comprises a main closing wall 21 which is planar or left, extending substantially parallel to the plane P of the rear face 14, to cover the housing 12a.

    Le couvercle 20 a des parois transversales 22 qui se rétrécissent de son extrémité de pied 22b qui est proche de 10b vers son extrémité de tête 22a qui est proche de 10a. Les parois 22 ont par exemple une forme générale trapézoïdale ou triangulaire et se terminent chacune par un crochet 23 destiné à prendre appui sur le corps en coopérant avec une prise 18 ménagée dans une paroi latérale 13 du corps à une distance notable de la paroi 21, par exemple à mi-distance entre les parois 21 et 14. Au lieu de crochets 23, on peut réaliser des pivots à encliquetage. Les prises 18 sont situées plus près de la paroi 15 que les formes 17 et en dessous de l'axe X (figure 2). Au milieu de son extrémité de tête 22a, le couvercle 20 présente un trou destiné à une vis 24, cette vis coopérant avec un trou taraudé du corps pour assurer la fixation du couvercle. The cover 20 has transverse walls 22 which narrow from its end foot 22b which is close to 10b towards its head end 22a which is close to 10a. The walls 22 have for example a general trapezoidal or triangular shape and each end with a hook 23 intended to bear on the body in cooperating with a socket 18 formed in a side wall 13 of the body at a significant distance from wall 21, for example halfway between walls 21 and 14. Instead of hooks 23, snap-in pivots can be produced. The sockets 18 are located closer to the wall 15 than the shapes 17 and below the X axis (figure 2). In the middle of its head end 22a, the cover 20 has a hole intended for a screw 24, this screw cooperating with a tapped hole in the body to ensure fixing the cover.

    Le couvercle 20 a une paroi dotée d'un évidement semi-circulaire qui forme une demi-collerette 26 complétant la demi-collerette 16 du corps 10. Des formes rectilignes 27 de guidage et de maintien du raccord 30 (verticales sur les figures), par exemple symétriques des formes 17 par rapport au plan d'assemblage, sont prévues à l'intérieur du couvercle. De plus, le couvercle 20 porte sur son pourtour un cordon d'étanchéité 28 bi-injecté destiné à coopérer avec le bord supérieur du corps qui borde le logement 12.The cover 20 has a wall with a semi-circular recess which forms a half-collar 26 completing the half-collar 16 of the body 10. Shapes rectilinear 27 for guiding and holding the connector 30 (vertical in the figures), for example symmetrical shapes 17 with respect to the assembly plane, are provided inside the cover. In addition, the cover 20 bears on its periphery a bi-injected sealing bead 28 intended to cooperate with the upper edge of the body bordering the housing 12.

    Le raccord 30 possède un corps 31 à forme générale de révolution doté d'un passage en partie fileté 32 d'axe X pour recevoir le câble C et une garniture non représentée assurant l'étanchéité locale autour du câble. La garniture est mise en pression par un organe non indiqué qui est vissé dans la partie filetée du passage 32.The connector 30 has a body 31 of general shape of revolution provided with a partly threaded passage 32 of axis X to receive cable C and a non-gasket shown ensuring local sealing around the cable. The trim is set pressure by an unspecified member which is screwed into the threaded part of the passage 32.

    Le raccord présente une partie cylindrique adaptée aux demi-collerettes 16,26, avec une gorge extérieure 33 dans laquelle se loge un joint torique d'étanchéité 34, lequel joint coopère donc avec les demi-collerettes ; dans sa partie destinée à se loger à l'intérieur du corps 10, le raccord 30 présente un cadre de montage 36 sensiblement carré ou rectangulaire. La joue 36 forme un cadre symétrique pourvu sur ses côtés de formes rectilignes d'insertion 37 complémentaires (par exemple nervures et/ou rainures) des formes 17 du corps de façon à permettre un montage amovible du raccord. Les formes 37 coopèrent avec les formes 17,27 par emboítement ; les formes en question peuvent avoir un effet d'encliquetage ou de point dur adjoint à l'effet d'emboítement.The connector has a cylindrical part adapted to the half-flanges 16,26, with an outer groove 33 in which is housed an O-ring seal 34, which seal therefore cooperates with the half-collars; in its part intended to be housed inside the body 10, the connector 30 has a mounting frame 36 substantially square or rectangular. Cheek 36 forms a symmetrical frame provided on its sides, complementary rectilinear insertion shapes 37 (for example ribs and / or grooves) of the shapes 17 of the body so as to allow mounting removable from the fitting. Forms 37 cooperate with forms 17.27 by interlocking; the shapes in question can have a ratcheting or hard point added to the nesting effect.

    Les raccords 30 peuvent ainsi différer par leur partie enserrant le câble et/ou par leur filetage de presse-étoupe tout en conservant une partie intégrée au corps, notamment une joue de montage 36, qui reste inchangée. La forme symétrique en H du cadre permet de le monter dans le corps dans deux positions décalées à 180° et d'obtenir un emboítement similaire dans le corps et dans le couvercle. The fittings 30 can thus differ by their part enclosing the cable and / or by their cable gland threads while retaining a part integrated into the body, in particular a mounting cheek 36, which remains unchanged. The symmetrical shape in H of the frame allows it to be mounted in the body in two positions offset 180 ° and get a similar fit in the body and in the cover.

    Le câblage du bloc interrupteur 12 s'effectue commodément alors que le bloc a été introduit selon la direction Y perpendiculaire à la paroi de fond 14 à l'intérieur de son logement 12a du corps 10. Le raccord 30 de type approprié au câble, et engagé sur le câble, est alors glissé dans les formes 17 selon la même direction Y, avec prise de contact du joint sur la demi-collerette 16. Le couvercle 20 est engagé par ses crochets 23 sur les prises 18 et par ses formes 27 sur les formes 37 du raccord, puis est mis en pivotement autour de ces prises, tandis que le joint torique 34 prend appui sur la demi-collerette 26. Le serrage de la vis unique de fixation 24 permet de mettre en pression le joint 34, et ce avec un effort accru par le décalage des crochets 18 par rapport au plan P de la paroi 21 du couvercle.The wiring of the switch block 12 is carried out conveniently while the block has been introduced in the direction Y perpendicular to the bottom wall 14 inside its housing 12a of the body 10. The fitting 30 of the type suitable for the cable, and engaged on the cable, is then slid into the forms 17 in the same direction Y, with plug of contact of the seal on the half-flange 16. The cover 20 is engaged by its hooks 23 on the sockets 18 and by its shapes 27 on the shapes 37 of the connector, then is pivoted around these sockets, while the O-ring 34 takes support on the half-collar 26. The tightening of the single fixing screw 24 makes it possible to pressurize the seal 34, and this with an increased effort by the offset of the hooks 18 relative to the plane P of the wall 21 of the cover.

    L'invention, décrite à propos d'un interrupteur de position ou de sécurité, s'applique aussi à tous détecteurs de proximité comprenant des blocs de connexion ou des blocs interrupteurs amovibles.The invention, described with regard to a position or safety switch, applies also to all proximity switches including connection blocks or removable switch blocks.
