Description

La présente invention concerne un dispositif de montage avec faculté de détrompage pour un bornier ou un connecteur sur un support. Un tel dispositif est notamment mais non exclusivement utilisable pour le montage d'un bornier sur un module d'interface dans un automate programmable.The present invention relates to a mounting device with the possibility of polarization for a terminal block or a connector on a support. Such a device is particularly but not exclusively usable for mounting a terminal block on an interface module in a programmable controller.

Il est connu d'utiliser d'après le brevet US-3 984 169 un dispositif de montage pivotant d'un organe de connexion sur un support d'appareils électriques tel qu'un tableau de distribution. Pour éviter de monter un organe de connexion inapproprié sur le support, on prévoit sur un axe fixe de pivotement et sur une pièce de palier solidaire de l'organe pivotant des moyens de codage constitués par des saillies et des encoches. Les moyens de codage permettent le détrompage recherché ; mais dans ce dispositif les moyens de pivotement et les moyens de codage sont relativement peu commodes.It is known to use according to US Pat. No. 3,984,169 a device for pivotally mounting a connection member on a support for electrical devices such as a distribution board. To avoid mounting an inappropriate connection member on the support, coding means constituted by protrusions and notches are provided on a fixed pivot axis and on a bearing part secured to the pivoting member. The coding means allow the sought-after polarization; but in this device the pivoting means and the coding means are relatively inconvenient.

L'invention a pour but de bien différencier, dans un dispositif de montage d'un bornier pivotant sur un support, le mouvement du bornier exécuté lors du détrompage de son mouvement pivotant exécuté lors de la connexion.The object of the invention is to clearly differentiate, in a device for mounting a pivoting terminal block on a support, the movement of the terminal block executed during the coding of its pivoting movement executed during connection.

Elle a pour autre but d'éviter, en cas d'erreur de montage, d'endommager le bornier ou l'ensemble du support.Another purpose is to avoid, in the event of an assembly error, damage to the terminal block or the entire support.

L'invention concerne un dispositif de montage d'un bornier sur un support, notamment sur un boîtier de module électronique, le bornier pouvant être relié électriquement au support par des éléments de connexion et fixé au support par des éléments de fixation, le dispositif comprenant

  • une pièce de palier qui sert au montage pivotant du bornier sur le support,
  • des moyens de codage associés au support et au bornier pour empêcher mécaniquement le montage d'un bornier inapproprié sur le support.
The invention relates to a device for mounting a terminal block on a support, in particular on an electronic module box, the terminal block being able to be electrically connected to the support by connection elements and fixed to the support by fixing elements, the device comprising
  • a bearing part which is used for pivoting mounting of the terminal block on the support,
  • coding means associated with the support and the terminal block to mechanically prevent the mounting of an inappropriate terminal block on the support.

Selon l'invention,

  • la pièce de palier est un organe rotatif porté par le boîtier du support et articulé audit boîtier ou respectivement porté par et articulé au corps du bornier,
  • l'organe articulé porte une première partie des moyens de codage et le bornier ou respectivement le boîtier du support, une deuxième partie - complémentaire de la première partie - des moyens de codage,
  • l'organe articulé est entraîné en rotation par le bornier - ou respectivement le support - au cours du montage du bornier sur le support.
According to the invention,
  • the bearing part is a rotary member carried by the support housing and articulated to said housing or respectively carried by and articulated to the body of the terminal block,
  • the articulated member carries a first part of the coding means and the terminal block or respectively the support housing, a second part - complementary to the first part - of the coding means,
  • the articulated member is driven in rotation by the terminal block - or respectively the support - during the mounting of the terminal block on the support.

De préférence, le bornier est emboîtable sur l'organe articulé de codage et les moyens de codage sont mutuellement engageables selon la direction de translation du bornier par rapport à l'organe articulé, cette direction étant contenue dans un plan perpendiculaire à l'axe d'articulation. Les surfaces coopérantes de guidage en translation sont avantageusement situées et agencées pour tendre à annuler le couple de rotation de l'organe articulé lors du guidage en translation.Preferably, the terminal block is nestable on the articulated coding member and the coding means are mutually engaging in the direction of translation of the terminal block relative to the articulated member, this direction being contained in a plane perpendicular to the axis d 'joint. The cooperating surfaces for guiding in translation are advantageously located and arranged to tend to cancel the torque of the articulated member during guiding in translation.

Les caractéristiques et avantages de l'invention ressortiront de la description d'un mode de réalisation non limitatif qui en est faite ci-après en regard des dessins annexés.The characteristics and advantages of the invention will emerge from the description of a non-limiting embodiment which is made of it below with reference to the appended drawings.

La figure 8 montre un mode de réalisation préféré de l'invention.Figure 8 shows a preferred embodiment of the invention.

Le dispositif représenté sur la figure 1 concerne le montage pivotant d'un bornier à l'avant d'un module d'interface dans un automate programmable ou un appareil d'automatisation analogue.The device represented in FIG. 1 relates to the pivoting mounting of a terminal block at the front of an interface module in a programmable controller or a similar automation device.

Le module d'interface 10 est fixé par tous moyens connus à un socle ou organe porteur non représenté et il sert à interfacer avec une unité électronique de traitement programmé un ensemble automatisé comprenant des organes d'entrée tels que des capteurs et des organes de sortie tels que des relais.The interface module 10 is fixed by any known means to a base or carrier member, not shown, and it is used to interface with an electronic programmed processing unit an automated assembly comprising input members such as sensors and output members. such as relays.

Le module 10 comprend un boîtier 11 muni sur sa face avant d'éléments de connexion mâles 12 et à sa partie inférieure un palier 13 d'axe horizontal X pour le pivotement du bornier 20. Celui-ci comprend un corps 21 qui, au montage, est amené en position inclinée jusqu'au palier 13 avant d'être dressé dans la position indiquée figure 1 et d'être fixé au boîtier 11 par tous moyens habituels 14 de fixation. Des câbles reliés aux organes d'entrée ou de sortie de l'ensemble automatisé sont électriquement raccordés à un circuit électronique du module 10 au moyen d'éléments de connexion femelles 23, par exemple groupés dans un connecteur, coopérant avec les éléments de connexion 12. Le bornier peut être démonté et remonté sur le module tout en conservant son câblage préétabli.The module 10 comprises a housing 11 provided on its front face with male connection elements 12 and at its lower part a bearing 13 of horizontal axis X for the pivoting of the terminal block 20. This comprises a body 21 which, on mounting , is brought into an inclined position up to the bearing 13 before being raised in the position indicated in FIG. 1 and being fixed to the housing 11 by any usual means 14 for fixing. Cables connected to the input or output members of the automated assembly are electrically connected to an electronic circuit of the module 10 by means of female connection elements 23, for example grouped in a connector, cooperating with the connection elements 12 The terminal block can be dismantled and reassembled on the module while retaining its pre-established wiring.

Pour éviter de monter sur le module d'interface considéré un bornier inapproprié, tout en utilisant autant que possible pour celui-ci un produit standardisé, on utilise un palier 13 qui comprend un organe articulé 30 prééquipé de pions de codage 40.To avoid mounting an inappropriate terminal block on the interface module considered, while using a standardized product as much as possible for this, a bearing 13 is used which includes an articulated member 30 pre-equipped with coding pins 40.

L'organe articulé 30 assure à la fois les fonctions de support pour les pions de codage, d'emboîtement du bornier et de palier pour celui-ci. Il comporte d'une part un élément de palier 31 d'axe X qui coopère avec un axe ou des pivots 15 fixes par rapport au boîtier 11, d'autre part un corps 32 qui présente deux logements 33 d'axes Y1,Y2 parallèles entre eux et contenus dans des plans P1,P2 perpendiculaires à l'axe X. Les logements 33 sont prismatiques, de section par exemple hexagonale, et débouchent chacun dans un petit orifice cylindrique 34. Chaque logement 33 reçoit initialement un couple de pions de codage 40a,40b (voir figure 2) indexés en rotation autour de l'axe respectif Y1,Y2. L'élément de palier 31 se monte sur l'axe 15 et il est raccordé au corps 32 par une zone affaiblie 36 qui peut se rompre lorsqu'on exerce sur l'organe 30 un effort excessif.The articulated member 30 ensures both the support functions for the coding pins, the fitting of the terminal block and the bearing for the latter. It comprises on the one hand a bearing element 31 of axis X which cooperates with an axis or pivots 15 fixed relative to the housing 11, on the other hand a body 32 which has two housings 33 of axes Y1, Y2 parallel between them and contained in planes P1, P2 perpendicular to the axis X. The housings 33 are prismatic, of section for example hexagonal, and each open into a small cylindrical orifice 34. Each housing 33 initially receives a couple of coding pins 40a, 40b (see Figure 2) indexed in rotation about the respective axis Y1, Y2. The bearing element 31 is mounted on the axis 15 and it is connected to the body 32 by a weakened zone 36 which can break when an excessive force is exerted on the member 30.

Chaque pion de codage 40 a une forme générale prismatique de section hexagonale tronquée, de manière à opérer comme il est bien connu en matière de détrompage mécanique, par exemple d'après le brevet US-3 426 315. Le pion 40 présente à une extrémité un téton 41. Le corps 21 du bornier possède à sa partie inférieure une partie 22 prévue pour coopérer avec l'organe rotatif. Cette partie 22 présente deux logements débouchant sur une ouverture 23 d'emboîtement sur la partie correspondante en saillie du corps 32 de l'organe 30 ; chaque logement présente un orifice prismatique 24 de section hexagonale qui s'ouvre d'un côté sur l'ouverture 23, du côté opposé sur un petit orifice cylindrique 25. Les tétons 41a,41b des pions 40a,40b coopèrent respectivement avec les orifices 34 de l'organe rotatif et les orifices 25 du bornier pour s'y emmancher à force. Chaque pion d'un couple a enfin un point dur ou élément analogue de retenue 42 qui lui permet de rester fixé à sa partie associée - support ou bornier - en dépit des efforts d'extraction qu'il reçoit de l'autre pion du couple.Each coding pin 40 has a general prismatic shape with a truncated hexagonal section, so as to operate as is well known in the field of mechanical coding, for example according to patent US Pat. No. 3,426,315. The pin 40 has at one end a stud 41. The body 21 of the terminal block has at its lower part a part 22 intended to cooperate with the rotary member. This part 22 has two housings opening onto an opening 23 for fitting onto the corresponding projecting part of the body 32 of the member 30; each housing has a prismatic orifice 24 of hexagonal section which opens on one side over the opening 23, on the opposite side on a small cylindrical orifice 25. The pins 41a, 41b of the pins 40a, 40b respectively cooperate with the orifices 34 of the rotary member and the orifices 25 of the terminal block for it press on. Each pawn of a couple finally has a hard point or similar retaining element 42 which allows it to remain fixed to its associated part - support or terminal block - despite the extraction forces it receives from the other pawn of the couple .

Le dispositif de montage et de détrompage représenté fonctionne comme il est indiqué sur les figures 5 à 7.The assembly and coding device shown operates as indicated in FIGS. 5 to 7.

Sur la figure 5, l'organe articulé de codage est montré en position inclinée, en butée sur un épaulement 16 du boîtier 11. L'organe 30 porte les deux couples de pions complémentaires 40a,40b emmanchés dans les logements 33. Lorsque le corps 21 du bornier 20 est engagé sur l'organe articulé 30 par translation selon la flèche B, il s'emmanche par l'ouverture 23 sur le corps 32 de l'organe rotatif et les pions 40a,40b sont introduits dans l'orifice hexagonal 24 jusqu'à ce que le téton 41b du pion 40b s'engage à force dans l'orifice 25. On peut dès lors faire pivoter le corps 21 du bornier autour de l'axe X selon la flèche C jusqu'à la position normale d'utilisation indiquée figure 6 ; dans cette position, les éléments de fixation peuvent être serrés.In FIG. 5, the articulated coding member is shown in an inclined position, in abutment on a shoulder 16 of the housing 11. The member 30 carries the two pairs of complementary pins 40a, 40b fitted into the housings 33. When the body 21 of the terminal block 20 is engaged on the articulated member 30 by translation along the arrow B, it is fitted through the opening 23 on the body 32 of the rotary member and the pins 40a, 40b are introduced into the hexagonal orifice 24 until the pin 41b of the pin 40b engages by force in the orifice 25. It is therefore possible to pivot the body 21 of the terminal block around the axis X according to the arrow C to the normal position of use indicated figure 6; in this position, the fasteners can be tightened.

Pour démonter le bornier, on le fait pivoter selon la flèche D (figure 7), puis on le retire par translation selon la flèche E. Le pion 40a reste retenu par son téton 41a et son point dur 42 dans le logement 33, tandis que le pion 40b reste maintenu par son téton 41b et son point dur 42 dans le logement 24. L'indexation des pions assure alors que seul un bornier équipé de pions 40b correctement indexés par rapport aux pions 40a pourra être monté sur le module.To disassemble the terminal block, it is rotated according to arrow D (FIG. 7), then it is removed by translation along arrow E. The pin 40a remains retained by its stud 41a and its hard point 42 in the housing 33, while the pin 40b remains held by its pin 41b and its hard point 42 in the housing 24. The indexing of the pins then ensures that only a terminal block equipped with pins 40b correctly indexed relative to the pins 40a can be mounted on the module.

Les deux couples de pièces prévus permettent de façon en soi connue 36 possibilités de codages. Il est clair que l'on peut obtenir un nombre différent de possibilités en choisissant le nombre de pièces de codage et leur forme.The two pairs of parts provided in a known manner allow 36 coding possibilities. It is clear that one can obtain a different number of possibilities by choosing the number of coding pieces and their shape.

Des indications visuelles, chiffrées par exemple, peuvent être adjointes aux logements des pions de codage. Bien que l'organe articulé de codage 30 puisse être adjoint au bornier, il est préférable qu'il soit adjoint au module d'interface comme il a été décrit ; ceci permet d'associer un bornier standard à des modules différents. Le bornier peut être solidarisé de l'organe articulé de codage par encliquetage.Visual indications, encrypted for example, can be added to the housing of the coding pins. Although the articulated coding member 30 can be added to the terminal block, it is preferable for it to be added to the interface module as described; this allows a standard terminal block to be associated with different modules. The terminal block can be secured to the articulated coding member by snap-fastening.

Dans le mode de réalisation préféré illustré sur la figure 8, l'organe articulé 30 est un barillet qui présente des surfaces planes 50 adjacentes à une surface convexe 51 dans laquelle débouchent les logements 33 d'axes Y1, Y2, ... destinés aux pions de codage. Le barillet présente des tourillons 52 d'axe X coplanaire et perpendiculaire à Y1, Y2, ... ; les tourillons sont engagés de façon amovible dans des logements de flasques 53 du boîtier 11 du module d'interface, afin de pouvoir pivoter autour de l'axe X par rapport au boîtier.In the preferred embodiment illustrated in FIG. 8, the articulated member 30 is a barrel which has planar surfaces 50 adjacent to a convex surface 51 into which open the housings 33 of axes Y1, Y2, ... intended for the coding pins. The barrel has journals 52 of axis X coplanar and perpendicular to Y1, Y2, ...; the pins are removably engaged in flange housings 53 of the housing 11 of the interface module, in order to be able to pivot around the axis X relative to the housing.

Le bornier 20 comprend des éléments de guidage destinés à coopérer avec les surfaces planes 50 du barillet. Les éléments de guidage sont ici constitués par les surfaces internes planes 54 de jupes 55 bordant une ouverture 56 pour permettre l'emboîtement selon la direction B. Dans le fond concave 57 de l'ouverture 56 débouchent les ouvertures 58 prévues pour les pions. Les jupes 55 se positionnent entre les deux flasques 53. L'engagement du bornier sur le barillet peut ainsi avoir lieu avec la précision souhaitée. Du fait de l'élasticité des flasques 53, les tourillons 52 du barillet peuvent se dégager de leurs logements lorsque le bornier transmet aux flasques des efforts de poussée excessifs.The terminal block 20 comprises guide elements intended to cooperate with the flat surfaces 50 of the barrel. The guide elements here consist of the flat internal surfaces 54 of skirts 55 bordering an opening 56 to allow nesting in direction B. In the concave bottom 57 of the opening 56 open the openings 58 provided for the pins. The skirts 55 are positioned between the two flanges 53. The engagement of the terminal block on the barrel can thus take place with the desired precision. Due to the elasticity of the flanges 53, the pins 52 of the barrel can disengage from their housings when the terminal block transmits excessive thrust forces to the flanges.
