Description

La présente invention a pour objet un dispositif de connexion d'un boítier électronique. Les boítiers électroniques utilisés dans le domaine de l'Industrie sont généralement montés dans des armoires, et sont juxtaposés les uns aux autres sur une même rangée, plusieurs rangées pouvant être superposées. Ces boítiers possèdent une forme générale parallélépipédique, et possèdent chacun une ou plusieurs broches de connexion en vue de réaliser leur connexion avec des câbles conducteurs reliés à différents types d'appareils tels que des systèmes d'horlogerie, des relais, ou des appareils de traitement du signal.The present invention relates to a connection device an electronic box. Electronic boxes used in the field are generally mounted in cabinets, and are juxtaposed to each other in the same row, several rows can be stacked. These boxes have a general shape rectangular, and each have one or more pins connection in order to make their connection with conductive cables connected to different types of devices such as clock systems, relays, or signal processing devices.

Les broches de connexion reliées à la carte électronique contenue dans chaque boítier électronique sont des broches plates d'orientation parallèles à la face longitudinale d'assemblage du boítier.Connection pins connected to the electronic card contained in each electronic box are flat pins orientation parallel to the longitudinal assembly face of the housing.

Compte tenu du fait que l'accessibilité à un boítier ne peut généralement se faire que par une face longitudinale, la connexion aux câbles conducteurs est réalisée par l'intermédiaire de modules de raccordement, fixés chacun sur la face longitudinale d'assemblage d'un boítier. Un module de raccordement contient des pièces de connexion aux broches plates horizontales, ainsi qu'un dispositif de fixation des câbles conducteurs qui sont mis en contact avec les pièces de connexion précitées. Les câbles conducteurs sont généralement introduits dans le module de raccordement soit par la face supérieure de celui-ci, soit par une face longitudinale de celui-ci.In view of the fact that accessibility to a box cannot generally only by a longitudinal face, the connection to conductive cables is carried out via modules connection, each fixed on the longitudinal assembly face of a housing. A connection module contains connection parts to horizontal flat pins, as well as a cable fixing device conductors which are brought into contact with the connection parts above. Conductive cables are generally introduced into the connection module either by the upper face thereof or by a longitudinal face thereof.

Un module de raccordement est fixé sur la face longitudinale d'assemblage d'un boítier par un dispositif d'encliquetage irréversible, l'approche du module vis-à-vis du boítier étant réalisée par déplacement transversal à cette face. Lorsqu'il est nécessaire d'intervenir sur un boítier, par exemple pour changer une carte électronique, il est nécessaire de démonter les liaisons entre les câbles conducteurs et le module de raccordement. Après intervention sur le boítier, il convient de raccorder les câbles conducteurs. Il résulte de ce qui précède que cette opération est une opération longue, coûteuse avec des risques d'erreurs lors du câblage.A connection module is fixed on the longitudinal face assembly of a housing by an irreversible latching device, the approach of the module vis-à-vis the housing being carried out by displacement transverse to this face. When it is necessary to intervene on a case, for example to change an electronic card, it is necessary to dismantle the connections between the conductor cables and the connection. After working on the housing, the conductor cables. It follows from the above that this operation is a long, costly operation with risk of errors during wiring.

Le but de l'invention est de fournir un dispositif de connexion d'un boítier électronique comportant un module de raccordement pouvant être câblé avant sa mise en place sur le boítier, et pouvant être démonté de façon simple et rapide du boítier, sans détérioration, et sans nécessiter le démontage des câbles conducteurs. Le but de l'invention est donc de fournir un dispositif dans lequel un module de raccordement puisse est démonté et remonté instantanément, sans désolidarisation des câbles conducteurs.The object of the invention is to provide a connection device an electronic box comprising a connection module which can be wired before its installation on the housing, and can be dismantled in a simple and fast way of the case, without deterioration, and without requiring disassembly of the conducting cables. The object of the invention is therefore to provide a device in which a connection module can be disassembled and reassembled instantly, without detaching the cables conductors.

A cet effet, ce dispositif, du type comprenant un module de raccordement destiné à être accouplé avec la face longitudinale d'assemblage d'un boítier et réalisant, d'une part, une liaison électrique avec des broches dépassant de cette face longitudinale d'assemblage et, d'autre part, une liaison électrique avec des câbles conducteurs, est caractérisé en ce que :

  • les broches de connexion dépassant de la face longitudinale d'assemblage d'un boítier sont des broches plates orientées parallèlement aux faces latérales du boítier adjacentes à des boítiers voisins,
  • la face longitudinale d'assemblage du boítier est délimitée latéralement par deux évidements parallèles partiellement obturés au niveau de la face longitudinale d'assemblage par au moins un ergot,
  • la face d'assemblage du module sur le boítier, comporte des fentes orientées parallèlement aux faces latérales, destinées chacune à recevoir une broche plate du boítier, avec possibilité de déplacement dans la direction des fentes du module par rapport au boítier jusqu'à une position de verrouillage dans laquelle chaque broche plate est engagée dans une pièce de connexion en forme de lyre disposée dans le module,
  • la face d'assemblage du module sur le boítier est délimitée latéralement sur une partie de sa hauteur par deux flancs parallèles qui font saillie vers l'avant et qui comportent chacun un retour vers l'intérieur présentant au moins un évidement, permettant, dans une position longitudinale déterminée, le passage des ergots du boítier puis la retenue de ceux-ci dans une autre position longitudinale correspondant à la position de verrouillage,
  • les faces d'assemblage respectivement du boítier et du module comportent respectivement, à proximité de leur extrémité opposée à celle comportant la connexion des broches, un évidement et une languette élastique escamotable destinée à venir s'engager dans l'évidement, en position verrouillée du module.
To this end, this device, of the type comprising a connection module intended to be coupled with the longitudinal assembly face of a housing and producing, on the one hand, an electrical connection with pins protruding from this longitudinal face. assembly and, on the other hand, an electrical connection with conductive cables, is characterized in that:
  • the connection pins protruding from the longitudinal assembly face of a housing are flat pins oriented parallel to the lateral faces of the housing adjacent to neighboring housings,
  • the longitudinal assembly face of the housing is delimited laterally by two parallel recesses partially closed at the longitudinal assembly face by at least one lug,
  • the assembly face of the module on the housing, has slots oriented parallel to the side faces, each intended to receive a flat pin of the housing, with the possibility of displacement in the direction of the slots of the module relative to the housing to a position locking mechanism in which each flat pin is engaged in a lyre-shaped connection piece arranged in the module,
  • the assembly face of the module on the housing is delimited laterally over part of its height by two parallel flanks which project forward and which each have a return inwardly having at least one recess, allowing, in a determined longitudinal position, the passage of the pins of the housing then the retention of these in another longitudinal position corresponding to the locking position,
  • the assembly faces respectively of the housing and of the module respectively comprise, near their end opposite to that comprising the connection of the pins, a recess and a retractable elastic tongue intended to come to engage in the recess, in the locked position of the module.

D'un point de vue pratique, un module de raccordement peut être prééquipé des câbles conducteurs. Pour réaliser la connexion au boítier électronique, il convient de réaliser une approche transversale du module en direction du boítier, le module étant décalé longitudinalement par rapport au boítier, afin que les ergots et retours respectivement du boítier et du module s'interpénètrent. Au cours de ce mouvement, les broches verticales du boítier pénètrent dans les fentes du module, les fentes étant disposées de telle sorte qu'aucun contact électrique n'ait lieu à ce stade du mouvement. Lorsque les faces en regard du boítier du module sont en contact, l'opérateur déplace le module longitudinalement, afin de réaliser le contact électrique puis le verrouillage qui est obtenu par engagement de la languette déformable appartenant au module dans l'évidement ménagé dans la face longitudinale d'assemblage du boítier. La retenue du module par rapport au boítier est réalisée par coopération entre les ergots du boítier et les retours du module, tandis que le verrouillage est réalisé par coopération entre la languette du module et l'évidement correspondant du boítier.From a practical point of view, a connection module can be pre-equipped with conductive cables. To make the connection to the box electronics, a transversal approach to the module should be carried out towards the housing, the module being offset longitudinally by report to the case, so that the lugs and returns respectively of the case and the module interpenetrate. During this movement, the pins vertical of the housing penetrate into the slots of the module, the slots being arranged so that no electrical contact takes place at this stage of the movement. When the facing faces of the module housing are in contact, the operator moves the module longitudinally, in order to carry out the electrical contact then the locking which is obtained by engagement of the deformable tongue belonging to the module in the recess in the longitudinal assembly face of the housing. The module restraint relative to the housing is achieved by cooperation between the lugs of the housing and module returns, while locking is accomplished by cooperation between the tab of the module and the corresponding recess of the housing.

L'actionnement de cette languette élastique, dans un sens de sortie hors de l'évidement dans laquelle elle est logée, permet, par translation longitudinale suivie d'un mouvement transversal, de démonter le module par rapport au boítier. Ce démontage est réalisé instantanément et permet d'accéder à l'intérieur du boítier. Il est remarquable de noter que ce démontage est effectué sans déconnecter les câbles conducteurs du module. Une intervention sur un boítier peut donc être effectuée de façon simple et très rapide puisqu'évitant toutes opérations ultérieures de câblage, le module qui a été désolidarisé du boítier avec les câbles qui lui sont raccordés pouvant être immédiatement remonté sur le boítier après intervention sur ce dernier, ou remplacement de ce dernier.The actuation of this elastic tongue, in a direction of outlet out of the recess in which it is housed, allows, by longitudinal translation followed by a transverse movement, to disassemble the module relative to the housing. This disassembly is carried out instantly and provides access to the interior of the housing. It is remarkable to note that this disassembly is carried out without disconnecting the conductive cables from the module. An intervention on a box can therefore be carried out in a way simple and very fast since avoiding all subsequent operations of wiring, the module which has been separated from the housing with the cables which are connected that can be immediately reassembled on the housing after intervention on the latter, or replacement thereof.

Afin de faciliter le travail de l'opérateur, les longueurs respectives des ergots du boítier et des évidements des retours du module sont déterminées pour former détrompeurs et pour ne permettre le montage que dans un sens du module sur le boítier.In order to facilitate the operator's work, the lengths respective lugs of the housing and recesses of the module returns are determined to form a key and not allow the mounting in one direction of the module on the housing.

En vue de simplifier le démontage du module de raccordement, celui-ci comporte, dans sa face adjacente à sa face d'assemblage avec le boítier, un évidement donnant accès à la languette élastique de verrouillage pour l'actionnement de celle-ci à l'aide d'un outil.In order to simplify the dismantling of the connection module, this comprises, in its face adjacent to its face for assembly with the housing, a recess giving access to the elastic locking tab to activate it using a tool.

Suivant une forme avantageuse d'exécution de ce dispositif, un module de raccordement comprend un corps à l'intérieur duquel sont montés un certain nombre de tiroirs dont chacun contient une pièce de connexion à une broche plate du boítier et au moins une pièce de fixation d'un câble conducteur.According to an advantageous embodiment of this device, a connection module comprises a body inside which are mounted a number of drawers each of which contains a piece of connection to a flat pin of the housing and at least one fixing part a conductive cable.

Chaque tiroir se présente sous la forme d'une pièce de forme générale parallélépipédique en matière synthétique dont l'une des faces latérales est ouverte et dont l'intérieur contient des cloisons dépassant de la face latérale opposée servant à l'appui et au maintien de la pièce de connexion en forme de lyre et de la ou des pièces de fixation des câbles conducteurs.Each drawer is in the form of a shaped part general parallelepiped in synthetic material of which one of the faces side is open and the interior contains partitions projecting from the opposite side face used to support and maintain the workpiece connection in the shape of a lyre and of the cable fixing part (s) conductors.

Plusieurs tiroirs se trouvent donc juxtaposés à l'intérieur du corps d'un module, la face ouverte de chaque tiroir étant adjacente à la face fermée du tiroir voisin.Several drawers are therefore juxtaposed inside the body of a module, the open face of each drawer being adjacent to the closed side of the neighboring drawer.

Afin de réaliser la fixation de chaque tiroir dans le corps du module, le tiroir comporte, sur ses deux faces adjacentes à la face ouverte, deux pattes d'encliquetage destinées à pénétrer dans deux évidements ménagés dans les parois en regard du module.In order to secure each drawer in the body of the module, the drawer has, on its two faces adjacent to the open face, two snap-on tabs intended to enter two recesses formed in the walls opposite the module.

Suivant un mode de réalisation de ce dispositif, la pièce de liaison électrique avec un câble conducteur est constituée par une épingle métallique en forme de boucle engagée sur un plot du tiroir faisant saillie de la face de celui-ci opposée à la face ouverte.According to one embodiment of this device, the part of electrical connection with a conductive cable consists of a pin metal in the form of a loop engaged on a stud of the protruding drawer from the face thereof opposite the open face.

Avantageusement, et dans le cas où il convient de réaliser la liaison électrique entre une pièce et deux câbles conducteurs, l'épingle, assurant la retenue d'au moins un câble, est une épingle double obtenue à partir d'une même lame métallique fendue sur sa longueur sauf dans une zone de liaison, les deux parties, disposées de part et d'autre de la fente, comportant chacune une ouverture pour le passage d'un câble et chaque partie d'épingle pouvant être actionnée indépendamment de l'autre partie pour réaliser la fixation d'un câble. Cette solution permet de ne mettre en oeuvre qu'un seul élément formant deux épingles, au lieu de deux épingles dans le cas traditionnel, ce qui est avantageux d'un point de vue économique, et simplifie les conditions de montage.Advantageously, and in the case where it is necessary to carry out the electrical connection between a part and two conducting cables, the pin, ensuring the retention of at least one cable, is a double pin obtained at from the same metal blade split along its length except in one connection zone, the two parts, arranged on either side of the slot, each comprising an opening for the passage of a cable and each pin part can be operated independently of the other part to fix a cable. This solution allows you to work that a single element forming two pins, instead of two pins in the traditional case, which is advantageous from a point of view economical, and simplifies mounting conditions.

De toute façon l'invention sera bien comprise, à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, plusieurs formes d'exécution de ce dispositif.In any case, the invention will be well understood, using the description which follows, with reference to the attached schematic drawing representing, by way of nonlimiting examples, several embodiments of this device.

La face d'assemblage 13 du module 12 est délimitée latéralement et sur une partie de sa longueur par deux flancs 15 parallèles qui font saillie sur l'avant et qui présentent chacun un retour 16 vers l'intérieur, chaque retour 16 présentant un évidement central 17 permettant, dans une position longitudinale déterminée du module par rapport au boítier 2, de réaliser le passage des ergots 9 du boítier puis la retenue de ceux-ci dans la position de verrouillage, les ergots 9 étant alors derrières les retours 16. Figure 1 also shows a connection module designated by the general reference 12. The assembly face 13 of the module on the housing has slots 14 oriented longitudinally, each intended to receive a flat pin 7 protruding from the housing, with possibility of moving each flat spindle 7 inside the corresponding slot 14 during a longitudinal displacement of the module by report to the housing. The assembly face 13 of the module 12 is delimited laterally and over part of its length by two parallel sides 15 which protrude from the front and each have a return 16 towards the interior, each return 16 having a central recess 17 allowing, in a determined longitudinal position of the module by compared to the housing 2, to carry out the passage of the lugs 9 of the housing then the retention of these in the locking position, the pins 9 then being behind returns 16.

La face d'assemblage 13 du module 12 comporte, à proximité de son extrémité supérieure, une languette élastique 18 destinée à venir s'engager dans l'évidement 10 du boítier 2, en position de verrouillage. Cette languette 18 est accessible par un évidement 19 débouchant dans la face supérieure du module 12. Dans la face supérieure 20 du module 12 sont ménagées trois ouvertures 22 pour l'engagement de conducteurs électriques, et trois ouvertures 23 permettant l'actionnement des moyens de retenue de ces conducteurs. Le référentiel utilisé ci-dessus tient compte de la position du module sur le dessin, mais ne correspond pas nécessairement à la position d'utilisation.The assembly face 13 of the module 12 comprises, near from its upper end, an elastic tongue 18 intended to come engage in the recess 10 in the housing 2, in the locked position. This tongue 18 is accessible by a recess 19 opening into the upper face of module 12. In upper face 20 of module 12 three openings 22 are provided for engaging conductors electrical, and three openings 23 allowing the actuation of the means retaining these conductors. The repository used above takes into account the position of the module on the drawing, but does not correspond necessarily in the position of use.

En pratique, il peut être procédé tout d'abord à la fixation des câbles dans le module 12. Une fois cette fixation réalisée, le module est approché transversalement du boítier, jusqu'à venir en butée contre celui-ci, avec interpénétration des ergots 9 et du retour 16 des flancs du module. Au cours de ce mouvement, les broches plates 7 pénètrent dans les fentes 14. Il est ensuite procédé à un déplacement longitudinal du module 12 vers le bas, mouvement au cours duquel est réalisée la connexion des broches plates 7 avec les pièces de connexion logées dans le module 12, et au cours duquel les retours 16 du module viennent se verrouiller derrière les ergots 9 du boítier 2. En fin de mouvement longitudinal, la languette élastique 18 pénètre dans l'évidement 10. Ce montage est réversible car il suffit, par exemple à l'aide d'un tournevis, de faire basculer la languette élastique 18 pour la dégager de l'évidement 10, avant de déplacer longitudinalement le module 12 pour permettre aux retours 16 d'échapper aux ergots 9 du boítier, et de tirer transversalement le module, pour permettre l'accès au boítier. Il est à noter que cette opération est effectuée sans démontage des câbles électriques.In practice, the fixing of the cables in module 12. Once this fixing is done, the module is approached transversely of the housing, until it comes into abutment against it, with interpenetration of lugs 9 and return 16 of the sides of the module. During this movement, the flat pins 7 penetrate into the slots 14. It is then carried out a longitudinal displacement of the module 12 downwards, movement during which the connection of the flat pins 7 with the connection parts housed in the module 12, and during which the returns 16 of the module come lock behind the lugs 9 of the housing 2. At the end of movement longitudinal, the elastic tongue 18 enters the recess 10. This mounting is reversible because it suffices, for example using a screwdriver, tilt the elastic tongue 18 to release it from the recess 10, before moving the module 12 longitudinally to allow the returns 16 to escape the pins 9 of the housing, and to shoot transversely the module, to allow access to the housing. It should be noted that this operation is carried out without dismantling the electric cables.

La figure 2 représente un détail de réalisation du module 12. Le module 12 comprend un corps dans lequel sont logés plusieurs tiroirs 24. Il y a autant de tiroirs 24 que de connexions à réaliser avec des broches plates 7. Chaque tiroir 24 est constitué par une pièce en matière synthétique, de forme générale parallélépipédique, dont l'une des faces 25 est ouverte. A l'intérieur du tiroir 24 sont ménagées des cloisons 26 et un plot 27 faisant saillie de la face 21 opposée à la face ouverte 25. Chaque tiroir 24 comporte sur deux faces opposées des pattes 28 d'encliquetage destinées à venir s'engager, comme montré à la figure 3, dans des ouvertures que comporte le boítier constitutif du module. Dans la forme d'exécution représentée au dessin, chaque tiroir 24 contient une pièce de connexion 29 conductrice en forme générale de S, montée contre des cloisons d'appui 26, et dont l'extrémité inférieure comporte une fente 30 en forme de lyre, cette fente 30 étant située en regard d'une fente 32 du tiroir 24, cette fente 32 étant elle-même située en regard d'une fente 14 du module. Une broche plate 7 va donc traverser la fente 14 du module, la fente 32 du tiroir 24 pour s'engager dans la fente 30 de la lyre de la pièce de connexion 29. Lors du mouvement transversal du module 12, il n'y a pas de contact électrique entre une broche 7 et la pièce 29. Lors du mouvement longitudinal du module, la broche 7 s'engage dans la fente 30 avec établissement du contact électrique avec la pièce 29.Figure 2 shows a detail of the module 12. module 12 comprises a body in which several drawers 24 are housed. there are as many drawers 24 as there are connections to be made with pins plates 7. Each drawer 24 is constituted by a piece of material synthetic, of generally parallelepiped shape, one of the faces 25 is open. Inside the drawer 24 are provided partitions 26 and a pad 27 projecting from the face 21 opposite the open face 25. Each drawer 24 has on two opposite faces latching lugs 28 intended to come and engage, as shown in Figure 3, in openings that includes the housing constituting the module. In the form shown in the drawing, each drawer 24 contains a piece of conductive connection 29 in general S shape, mounted against support partitions 26, and the lower end of which has a slot 30 lyre-shaped, this slot 30 being located opposite a slot 32 of the drawer 24, this slot 32 being itself located opposite a slot 14 of the module. A flat pin 7 will therefore pass through the slot 14 of the module, the slot 32 of drawer 24 for engaging in slot 30 of the lyre of the part 29. During the transverse movement of the module 12, there is no electrical contact between a spindle 7 and the part 29. When longitudinal movement of the module, pin 7 engages in slot 30 with establishment of electrical contact with part 29.

Le tiroir 24 contient également une pièce 33 en forme d'épingle refermée sur elle-même, cette épingle étant une épingle élastique de type connu en soi, présentant une ouverture 34 pour le passage d'un câble conducteur. En pratique, avant engagement d'un câble conducteur, un outil tel qu'un tournevis est engagé dans l'ouverture 23 du module pour déformer l'épingle 33 et dégager l'ouverture 34 de celle-ci en l'amenant en regard de l'ouverture 22 par laquelle le câble conducteur est engagé. Lorsque l'extrémité du câble conducteur est en contact avec la pièce de connexion 29, l'action exercée par l'outil sur l'épingle 33 est relâchée et celle-ci se détend en assurant la fixation du câble conducteur.The drawer 24 also contains a pin-shaped part 33 closed on itself, this pin being an elastic pin of the type known per se, having an opening 34 for the passage of a cable driver. In practice, before engaging a conductor cable, a tool such as a screwdriver is engaged in the opening 23 of the module to deform the pin 33 and disengage the opening 34 from the latter by bringing it in look of the opening 22 through which the conductive cable is engaged. When the end of the conductor cable is in contact with the workpiece connection 29, the action exerted by the tool on the pin 33 is released and it relaxes by securing the conductor cable.

La figure 4 représente une vue de dessus d'une variante d'un module, dans lequel les mêmes éléments sont désignés par les mêmes références que précédemment. Dans ce cas, il s'agit de réaliser la connexion de chaque broche plate 7 avec deux conducteurs électriques. A cet effet, chaque tiroir est équipé, non pas de deux épingles, mais d'une épingle double 36 réalisée à partir d'une même lame métallique, séparée en deux parties 37 disposées de part et d'autre d'une fente 38, les deux parties 37 demeurant solidaires par l'une 39 des extrémités de l'épingle. Une ouverture 34 est ménagée dans chacune des parties 37 de l'épingle, chaque ouverture 34 étant destinée à permettre le passage d'un élément conducteur. Cette épingle double présente l'avantage de n'être constituée que par une seule pièce au lieu de deux et de ne nécessiter la mise en place que d'une seule pièce au lieu de deux, ce qui constitue un avantage économique. Figure 4 shows a top view of a variant of a module, in which the same elements are designated by the same references than before. In this case, it is a question of carrying out the connection of each flat pin 7 with two electrical conductors. AT For this purpose, each drawer is equipped, not with two pins, but with a double pin 36 made from the same metal blade, separated into two parts 37 arranged on either side of a slot 38, both parts 37 remaining integral by one 39 of the ends of the pin. An opening 34 is formed in each of the parts 37 of the pin, each opening 34 being intended to allow the passage of an element driver. This double pin has the advantage of not being made up only by one piece instead of two and only require the setting place only one piece instead of two, which is an advantage economic.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un dispositif de connexion d'un boítier électrique, de structure simple, permettant une déconnexion simple et non destructrice, et d'une mise en oeuvre très pratique pour les utilisateurs.As is apparent from the above, the invention provides a great improvement to the existing technique by providing a device for connection of an electrical box, of simple structure, allowing a simple and non-destructive disconnection, and very easy to use convenient for users.

Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de ce dispositif, décrites ci-dessus à titre d'exemples, elle en embrasse au contraire toutes les variantes. C'est ainsi notamment que les moyens de liaison des câbles conducteurs pourraient être constitués par des moyens à vis et étriers, sans que l'on sorte pour autant du cadre de l'invention.It goes without saying that the invention is not limited only to embodiments of this device, described above by way of examples, on the contrary, it embraces all its variants. This is how that the means of connecting the conducting cables could be formed by means of screws and stirrups, without being removed of the scope of the invention.
