Description

La présente invention concerne un module de connexion interchangeable et un système électrique comprenant un appareil électrique de commutation et un tel module de connexion interchangeable.The present invention relates to an interchangeable connection module and an electrical system comprising an electrical switching device and such an interchangeable connection module.

Un module de connexion interchangeable est connu de WO-2014 209 143 A1 .An interchangeable connection module is known from WO-2014 209 143 A1 .

Les appareils de commutation électrique, tels que les disjoncteurs, les contacteurs, les sectionneurs, ou encore les relais, sont typiquement associés à des installations électriques afin d'en piloter le fonctionnement et/ou d'assurer une protection électrique.Electrical switching devices, such as circuit breakers, contactors, disconnectors, or even relays, are typically associated with electrical installations in order to control their operation and / or to provide electrical protection.

Ces appareils de commutation sont donc destinés à être raccordés électriquement à une installation électrique. Ce raccordement est réalisé par l'intermédiaire de conducteurs électriques, ou liaisons électriques, généralement filaires, que l'on connecte à des terminaux de raccordement de l'appareil.These switching devices are therefore intended to be electrically connected to an electrical installation. This connection is made by means of electrical conductors, or electrical connections, generally wired, which are connected to connection terminals of the device.

Un inconvénient est qu'il existe un grand nombre de façons de réaliser ce raccordement. Par exemple, il est connu d'utiliser des conducteurs filaires se terminant par des câbles nus, ou par des cosses ouvertes, ou par des cosses fermées, ou par d'autres types de connecteurs. Les terminaux de raccordement de l'appareil doivent donc être adaptés en conséquence. Ainsi, un même appareil de commutation doit être décliné en plusieurs variantes, chacune adaptée à un type de raccordement particulier. Cette situation n'est pas satisfaisante d'un point de vue industriel, car elle oblige à multiplier le nombre de références pour chaque type d'appareil.One drawback is that there are a large number of ways to achieve this connection. For example, it is known to use wire conductors terminating in bare cables, or in open terminals, or in closed terminals, or in other types of connectors. The device connection terminals must therefore be adapted accordingly. Thus, the same switching device must be available in several variants, each adapted to a particular type of connection. This situation is not satisfactory from an industrial point of view, because it makes it necessary to multiply the number of references for each type of device.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un module de connexion pour un appareil de commutation électrique, permettant une meilleure polyvalence, une connexion améliorée ainsi qu'une plus grande souplesse d'utilisation.It is these drawbacks that the invention more particularly intends to remedy by proposing a connection module for an electrical switching device, allowing better versatility, improved connection as well as greater flexibility of use.

La figure 1 représente un exemple d'un système électrique comportant un appareil électrique de commutation 1 associé à un module de connexion 2 interchangeable. Le module de connexion 2, aussi nommé bornier, permet de raccorder électriquement l'appareil 1 à une installation électrique au moyen de liaisons électriques 3, telles que des câbles. Le module de connexion 2 est déplaçable entre une position connectée avec l'appareil 1 et une position déconnectée de l'appareil 1.The figure 1 shows an example of an electrical system comprising an electrical switching device 1 associated with an interchangeable connection module 2. The connection module 2, also called a terminal block, allows the device 1 to be electrically connected to an electrical installation by means of electrical connections 3, such as cables. The connection module 2 can be moved between a position connected with the device 1 and a position disconnected from the device 1.

L'appareil 1 est ici un appareil de coupure d'un courant électrique, tel qu'un disjoncteur. Selon des variantes, l'appareil 1 est un contacteur, ou un sectionneur, ou tout autre appareil de protection électrique et/ou de commutation électrique.The device 1 is here a device for cutting an electric current, such as a circuit breaker. According to variants, the device 1 is a contactor, or a disconnector, or any other electrical protection and / or electrical switching device.

Comme illustré aux figures 1, 4, 5 et 6, l'appareil 1 comporte un boîtier et une interface de raccordement 10 destinée à recevoir le module de connexion 2.As shown in figures 1 , 4, 5 and 6 , the device 1 comprises a housing and a connection interface 10 intended to receive the connection module 2.

Dans l'exemple illustré, le module de raccordement 2 est adapté pour connecter deux conducteurs 3 à deux pôles distincts correspondants de l'appareil 1. Ce nombre de pôles n'est cependant pas limitatif et, selon d'autres modes de réalisation, le nombre de pôles est différent, par exemple supérieur à deux, ou égal à un.In the example illustrated, the connection module 2 is suitable for connecting two conductors 3 to two corresponding separate poles of the device 1. This number of poles is however not limiting and, according to other embodiments, the number of poles is different, for example greater than two, or equal to one.

Pour chacun des pôles, l'interface 10 comprend un contact électrique 11 et une lame de maintien 12 élastique.For each of the poles, the interface 10 comprises an electrical contact 11 and a resilient retaining strip 12.

Le contact 11 joue le rôle de terminal de raccordement destiné à raccorder électriquement l'appareil 1 à une installation extérieure, permettant ainsi d'acheminer un courant électrique entre l'appareil 1 et l'extérieur. Le contact 11 est par exemple une pièce rigide en matière métallique, telle que du cuivre.The contact 11 acts as a connection terminal intended to electrically connect the device 1 to an external installation, thus making it possible to route an electric current between the device 1 and the outside. Contact 11 is for example a rigid part made of metallic material, such as copper.

Lorsque le module 2 est connecté avec l'appareil 1, chaque liaison 3 est raccordée à un contact 11 par l'intermédiaire d'une pièce de raccordement 21 du module 2, décrite ci-après.When the module 2 is connected with the device 1, each link 3 is connected to a contact 11 by means of a connection piece 21 of the module 2, described below.

La lame 12 est déformable élastiquement entre une position enfoncée et une position relâchée. Une extrémité de la lame 12 est solidaire du boîtier de l'appareil 1, alors qu'une extrémité opposée est maintenue libre. Par exemple, la lame 12 est réalisée en matière métallique.The blade 12 is elastically deformable between a depressed position and a relaxed position. One end of the blade 12 is integral with the housing of the device 1, while an opposite end is kept free. For example, the blade 12 is made of metallic material.

De façon générale, chaque lame 12 est agencée de telle sorte que, lorsque le module 2 est connecté avec l'appareil 1 et que la lame 12 est dans sa position relâchée, chaque pièce de raccordement 21 du module 2 est maintenue en contact avec un contact électrique 11 correspondant grâce à l'effort d'appui exercé par cette lame 12. Dit autrement, la lame 12 touche la pièce de raccordement 21. Ce maintien s'oppose au retrait par translation de la pièce de raccordement 21. Lorsque la lame 12 est dans sa position enfoncée, elle n'exerce en revanche pas ce maintien sur la pièce de raccordement 21. La lame 12 est agencée pour revenir élastiquement vers sa position relâchée, par exemple grâce à sa forme et/ou à la nature du matériau utilisé.In general, each blade 12 is arranged such that, when the module 2 is connected with the device 1 and the blade 12 is in its released position, each connecting piece 21 of the module 2 is kept in contact with a corresponding electrical contact 11 thanks to the bearing force exerted by this blade 12. In other words, the blade 12 touches the connecting piece 21. This maintenance opposes the withdrawal by translation of the connecting piece 21. When the blade 12 is in its depressed position, on the other hand it does not exercise this retention on the connecting piece 21. The blade 12 is arranged to return elastically to its released position, for example by virtue of its shape and / or the nature of the material. used.

Dans cet exemple, la lame 12 présente une forme recourbée. De façon purement illustrative et non limitative, la lame 12 présente ici une forme recourbée sur elle-même de telle sorte que sa section prise selon un plan vertical de l'appareil 1 présente une forme en épingle à cheveux, comme illustré plus spécifiquement sur les figures 4 à 6. D'autres configurations de la lame 12 sont toutefois possibles, par exemple une forme en lame droite et verticale.In this example, the blade 12 has a curved shape. In a purely illustrative and non-limiting manner, the blade 12 here has a shape curved on itself such that its section taken along a vertical plane of the device 1 has a hairpin shape, as illustrated more specifically in the figures 4 to 6 . Other configurations of the blade 12 are however possible, for example a straight and vertical blade shape.

De préférence, les contacts 11 et les lames 12 sont disposés derrière une paroi 13 de l'appareil 1. Cela limite le risque qu'un utilisateur y accède accidentellement.Preferably, the contacts 11 and the blades 12 are arranged behind a wall 13 of the device 1. This limits the risk that a user accidentally accesses it.

La paroi 13 fait ici partie du boîtier de l'appareil 1. Dans cet exemple, la paroi 13 forme une face avant de l'appareil 1.The wall 13 here forms part of the housing of the device 1. In this example, the wall 13 forms a front face of the device 1.

La paroi 13 comporte, pour chaque pôle, des fentes traversantes 14, 15 qui permettent un accès, respectivement, au contact électrique 11 et à la lame de maintien 12 depuis l'extérieur du boîtier de l'appareil 1.The wall 13 comprises, for each pole, through slots 14, 15 which allow access, respectively, to the electrical contact 11 and to the retaining blade 12 from outside the housing of the device 1.

Dans cet exemple, pour chaque pôle, le contact électrique 11 et la lame 12 sont superposés l'un au-dessus de l'autre. Les pôles de l'appareil 1 sont disposés côte à côte.In this example, for each pole, the electrical contact 11 and the blade 12 are superimposed one above the other. The poles of the device 1 are arranged side by side.

L'appareil 1 comporte avantageusement une interface de verrouillage pour connecter mécaniquement le module 2 de façon amovible sur le boîtier de l'appareil 1.The device 1 advantageously comprises a locking interface for mechanically connecting the module 2 in a removable manner to the housing of the device 1.

Selon un exemple, l'appareil 1 comporte à cet effet des rainures 16 dont le rôle est décrit dans ce qui suit. Dans l'exemple illustré, les rainures 16 sont disposées verticalement.According to one example, the device 1 comprises for this purpose grooves 16, the role of which is described below. In the example illustrated, the grooves 16 are arranged vertically.

Comme illustré aux figures 2 et 3, le module 2 comporte un boîtier 20 et, pour chaque pôle, une pièce de raccordement 21 et un élément de fixation 22.As shown in figures 2 and 3 , the module 2 comprises a housing 20 and, for each pole, a connection piece 21 and a fixing element 22.

Sur la figure 2, on note « X2 » un axe géométrique longitudinal du module 2 et on note « Z2 » un axe géométrique transversal vertical du module 2 perpendiculaire à l'axe X2.On the figure 2 , a longitudinal geometric axis of the module 2 is denoted "X2" and a vertical transverse geometric axis of the module 2 is denoted "Z2" at right angles to the axis X2.

Par exemple, le boîtier 20 est réalisé par moulage en un matériau polymère, tel que du plastique.For example, the housing 20 is made by molding from a polymeric material, such as plastic.

Chaque pièce de raccordement 21 est destinée à assurer une connexion électrique entre une liaison 3 et un des contacts 11 de l'appareil 1. De préférence, la pièce 21 est réalisée en matière métallique, par exemple en cuivre.Each connection piece 21 is intended to provide an electrical connection between a link 3 and one of the contacts 11 of the device 1. Preferably, the piece 21 is made of metallic material, for example copper.

Chaque pièce 21 comporte au moins une portion de raccordement 212 qui s'étend en saillie hors du boîtier 20. Par exemple, la portion de raccordement 212 présente une forme allongée parallèlement à l'axe X2, en forme de lame ou de tige.Each part 21 comprises at least one connection portion 212 which projects out of the housing 20. For example, the connection portion 212 has an elongated shape parallel to the axis X2, in the form of a blade or rod.

Avantageusement, les portions de raccordement 212 comportent des crans 214 pour recevoir l'extrémité libre de la lame 12. Ces crans 214 procurent une tenue mécanique supérieure du module 2 lorsqu'il est connecté avec l'appareil 1.Advantageously, the connection portions 212 include notches 214 to receive the free end of the blade 12. These notches 214 provide greater mechanical strength of the module 2 when it is connected with the device 1.

Chaque élément de fixation 22 est associé à une pièce de raccordement 21 et est adapté pour assurer une connexion mécanique du l'extrémité de la liaison 3 avec la pièce de raccordement 21 correspondante.Each fastening element 22 is associated with a connecting piece 21 and is adapted to ensure a mechanical connection of the end of the link 3 with the corresponding connecting piece 21.

Dans un souci de simplification, les pièces de raccordement 21 sont ici identiques entre elles et les éléments 22 sont ici eux aussi identiques entre eux, de sorte que seul un exemplaire de chacun d'entre eux est décrit en détail.For the sake of simplicity, the connecting pieces 21 are here identical to each other and the elements 22 are here also identical to each other, so that only one copy of each of them is described in detail.

La forme des pièces de raccordement 21 est adaptée en fonction du type de connexion utilisée sur les extrémités des liaisons 3.The shape of the connecting pieces 21 is adapted according to the type of connection used on the ends of the links 3.

Dans l'exemple illustré, les liaisons 3 sont des câbles formés d'une portion centrale 31 électriquement conductrice entourée d'une gaine électriquement isolante 32. Sur l'extrémité de la liaison 3 destinée à être connectée, la portion centrale 31 est dénudée pour permettre la connexion électrique avec la pièce de raccordement 21.In the example illustrated, the links 3 are cables formed of a central electrically conductive portion 31 surrounded by an electrically insulating sheath 32. On the end of the link 3 intended to be connected, the central portion 31 is stripped for allow the electrical connection with the connection piece 21.

Selon le mode de réalisation illustré, chaque pièce de raccordement 21 comporte une plaque de contact 221, ici de forme plane, et deux portions de raccordement 212, ici en forme de lame, qui s'étendent en saillie perpendiculairement par rapport à la plaque de contact 211. La plaque de contact 211 est percée d'un orifice traversant 213 de préférence taraudé. La plaque de contact 211 et les portions de raccordement 212 sont ici ménagées d'un seul tenant.According to the illustrated embodiment, each connection piece 21 comprises a contact plate 221, here of planar shape, and two connection portions 212, here in the form of a blade, which protrude perpendicularly relative to the plate. contact 211. The contact plate 211 is pierced with a through orifice 213, preferably threaded. The contact plate 211 and the connection portions 212 are here provided in one piece.

Dans cet exemple illustratif, l'appareil 1 comporte, pour chacune des pièces de raccordement 21, c'est-à-dire pour chaque pôle, autant de lames 12 que de portions de raccordement 212. Ici, il y a deux lames 12 différentes pour chaque pôle. Chacune de ces deux lames 12 est destinée à venir en contact avec l'une des portions de raccordement 212. Cela permet d'améliorer la fixation du boîtier 2 lorsqu'il est connecté avec l'appareil 1. En variante, le nombre de lames 12 pour chaque pôle peut être différent.In this illustrative example, the device 1 comprises, for each of the connecting pieces 21, that is to say for each pole, as many blades 12 as there are connecting portions 212. Here, there are two different blades 12. for each pole. Each of these two blades 12 is intended to come into contact with one of the connecting portions 212. This improves the fixing of the housing 2 when it is connected with the device 1. As a variant, the number of blades 12 for each pole may be different.

Les éléments de fixation 22 comportent chacun une vis 221 et un étrier 222. Pour raccorder une liaison 3 à la pièce de raccordement 21 correspondante, l'extrémité de la portion centrale 31 dénudée est mise en contact avec la plaque de contact 211 et est maintenue grâce à l'étrier 222 par serrage de la vis 221. L'orifice 213 permet de recevoir l'extrémité de la vis 221.The fixing elements 22 each comprise a screw 221 and a bracket 222. To connect a link 3 to the corresponding connection piece 21, the end of the stripped central portion 31 is brought into contact with the contact plate 211 and is held. thanks to the bracket 222 by tightening the screw 221. The orifice 213 makes it possible to receive the end of the screw 221.

Selon des variantes non illustrées, le raccordement des liaisons 3 est réalisé différemment, par exemple au moyen de cosses ménagées aux extrémités des liaisons 3. Les pièces de raccordement 21 et/ou les éléments de fixation 22 sont alors adaptées en conséquence, par exemple en intégrant un connecteur de forme complémentaire.According to variants not shown, the connection of the links 3 is made differently, for example by means of thimbles formed at the ends of the links 3. The connecting pieces 21 and / or the fixing elements 22 are then adapted accordingly, for example by integrating a connector of complementary shape.

Les éléments de fixation 22 peuvent alors être omis. Alternativement, les éléments de fixation 22 peuvent être intégrés aux pièces de raccordement 21.The fasteners 22 can then be omitted. Alternatively, the fastening elements 22 can be integrated into the connecting pieces 21.

Selon d'autres modes de mise en oeuvre, un même module 2 peut être adapté pour recevoir des conducteurs 3 raccordés de façon différente. En d'autres termes, les pièces de raccordement 21 et les éléments de fixation 22 d'un même module 2 peuvent être réalisés différemment.According to other embodiments, the same module 2 can be adapted to receive conductors 3 connected in different ways. In other words, the connecting pieces 21 and the fastening elements 22 of the same module 2 can be made differently.

Le module 2 comporte également un bouton d'actionnement 23, déplaçable par translation, par rapport au boîtier 20, entre une position de repos et une position appuyée, selon une direction de déplacement ici parallèle à l'axe X2. Le bouton 23 est destiné à être actionné par un utilisateur depuis l'extérieur du boîtier 20.The module 2 also comprises an actuation button 23, movable by translation, relative to the housing 20, between a rest position and a pressed position, in a direction of movement here parallel to the axis X2. The button 23 is intended to be actuated by a user from outside the housing 20.

Le bouton 23 est par exemple réalisé en un matériau rigide, tel qu'un matériau plastique moulé. Le bouton 23 est préférentiellement réalisé d'un seul tenant.The button 23 is for example made of a rigid material, such as a molded plastic material. The button 23 is preferably made in one piece.

Par exemple, le bouton 23 est associé à des moyens de rappel élastiques, tel qu'un ou plusieurs ressorts, qui ramènent élastiquement le bouton 23 vers sa position de repos.For example, the button 23 is associated with elastic return means, such as one or more springs, which resiliently return the button 23 to its rest position.

Le bouton 23 comporte des portions d'appui 231, rigides et solidaires du corps du bouton 23, qui s'étendent en saillie hors du boîtier 20 lorsque le bouton 23 est dans sa position appuyée. Il y a au moins une portion d'appui 231 pour chaque pôle.The button 23 comprises support portions 231, rigid and integral with the body of the button 23, which project out from the housing 20 when the button 23 is in its pressed position. There is at least a bearing portion 231 for each pole.

Les portions d'appui 231 sont adaptées pour déplacer les lames 12 correspondantes vers leur position enfoncée lorsque le module 2 est connecté avec l'appareil 1 et que le bouton 23 est déplacé vers sa position appuyée.The support portions 231 are adapted to move the corresponding blades 12 to their depressed position when the module 2 is connected with the device 1 and the button 23 is moved to its depressed position.

Par exemple, chaque portion d'appui 231 est alignée en regard d'une lame 12 parallèlement à l'axe de déplacement du bouton 23.For example, each bearing portion 231 is aligned facing a blade 12 parallel to the axis of movement of the button 23.

Dans l'exemple illustré, chaque portion d'appui 231 comporte deux doigts allongés et s'étend parallèlement à la direction X2.In the example illustrated, each bearing portion 231 comprises two elongated fingers and extends parallel to the direction X2.

Les portions 212 et les portions d'appui 231 sont ici superposées verticalement l'une avec l'autre, de façon correspondante à la disposition du contact 11 et de la lame 12.The portions 212 and the bearing portions 231 are here superimposed vertically with one another, correspondingly to the arrangement of the contact 11 and of the blade 12.

On comprend donc que les fentes 14 et 15 sont agencées et dimensionnées de sorte à permettre le passage des portions de raccordement 212 et des portions d'appui 231, respectivement.It is therefore understood that the slots 14 and 15 are arranged and dimensioned so as to allow the passage of the connection portions 212 and the bearing portions 231, respectively.

Le bouton 23 comporte également un poussoir 233 formant une surface sur laquelle un utilisateur peut appuyer pour déplacer le bouton 23, par exemple au moyen d'un outil 4 ou directement avec ses doigts.The button 23 also comprises a pusher 233 forming a surface on which a user can press to move the button 23, for example by means of a tool 4 or directly with his fingers.

Selon des modes de mise en œuvre optionnels, le poussoir 233 forme une excroissance qui dépasse au travers de l'ouverture 207 au dehors du boîtier 20 lorsque le bouton 23 est dans sa position de repos. Cela permet à un utilisateur d'appuyer plus facilement sur le bouton 23 pour le déplacer vers la position appuyée sans avoir besoin d'un outil 4.According to optional embodiments, the pusher 233 forms a protuberance which protrudes through the opening 207 outside the housing 20 when the button 23 is in its rest position. This makes it easier for a user to press button 23 to move it to the pressed position without the need for a tool 4.

De façon optionnelle, le déplacement en translation du bouton 23 par rapport au boîtier 20 est facilité grâce à des éléments de guidage 234 qui coopèrent avec des rails de guidage, non illustrés, disposés à l'intérieur du boîtier 20.Optionally, the translational movement of the button 23 relative to the housing 20 is facilitated by means of guide elements 234 which cooperate with guide rails, not shown, arranged inside the housing 20.

De préférence, le bouton 23 est logé à l'intérieur du boîtier 20 en étant séparé des pièces de raccordement 21 et des éléments de fixation 22 par un écran 203 électriquement isolant. Cela limite le risque qu'un utilisateur appuyant sur le bouton 23 se trouve accidentellement en contact électrique avec les pièces de raccordement 21 ou avec les liaisons 3.Preferably, the button 23 is housed inside the housing 20 while being separated from the connection pieces 21 and the fixing elements 22 by an electrically insulating screen 203. This limits the risk that a user pressing button 23 will get accidentally comes into electrical contact with the connection pieces 21 or with the connections 3.

Selon des modes de mise en oeuvre, comme illustré à la figure 2, le boîtier 20 comporte une première partie de boîtier 201, qui contient les pièces de raccordement 21 et au moins une partie des éléments de fixation 22, et une deuxième partie de boîtier 202, qui contient le bouton 23. La deuxième partie 202 inclut l'écran isolant 203.According to embodiments, as illustrated in figure 2 , the housing 20 has a first housing part 201, which contains the connecting pieces 21 and at least part of the fasteners 22, and a second housing part 202, which contains the button 23. The second part 202 includes the 'insulating screen 203.

Dans cet exemple, la partie de boîtier 201 comporte des premières ouvertures 205 permettant le passage d'un outil pour régler les éléments de fixation 22, et comporte des deuxièmes ouvertures 206 permettant le passage des extrémités des liaisons 3. La partie de boîtier 202 comporte une ouverture 207 autorisant le passage du poussoir 233.In this example, the housing part 201 comprises first openings 205 allowing the passage of a tool for adjusting the fixing elements 22, and comprises second openings 206 allowing the passage of the ends of the links 3. The housing part 202 comprises an opening 207 allowing the passage of the pusher 233.

Avantageusement, le module 2 comporte un dispositif de verrouillage complémentaire avec l'interface de verrouillage ménagée sur l'appareil 1. Ce dispositif de verrouillage est avantageusement actionnable par le bouton 23.Advantageously, the module 2 comprises a complementary locking device with the locking interface provided on the device 1. This locking device can advantageously be actuated by the button 23.

Selon des modes de réalisation, le module 2 comporte à cet effet des crochets mobiles 24. Les crochets 24 sont ici destinés à coopérer avec les rainures 16. Par exemple, les rainures 16 comportent une portion d'accroche sur lesquelles les crochets 24 prennent appui.According to embodiments, the module 2 comprises for this purpose movable hooks 24. The hooks 24 are here intended to cooperate with the grooves 16. For example, the grooves 16 comprise a hooking portion on which the hooks 24 rest. .

Comme illustré aux figures 7 et 8, les crochets 24 sont montés pivotants, par rapport au boîtier 20, autour d'axes de rotation parallèles à l'axe Z2. Les crochets 24 sont déplaçables entre une position fermée, illustrée sur la figure 7, et une position ouverte, illustrée sur la figure 8.As shown in figures 7 and 8 , the hooks 24 are mounted to pivot, relative to the housing 20, about axes of rotation parallel to the axis Z2. The hooks 24 are movable between a closed position, shown in figure 7 , and an open position, shown on figure 8 .

Lorsque le module 2 est connecté avec l'appareil 1 et que les crochets 24 sont dans leur position fermée, ceux-ci sont reçus dans les rainures 16 et solidarisent le module 2 à l'appareil 1 en empêchant le retrait du module X2 par translation selon l'axe X2.When the module 2 is connected with the device 1 and the hooks 24 are in their closed position, these are received in the grooves 16 and secure the module 2 to the device 1 by preventing the removal of the module X2 by translation along the X2 axis.

En d'autres termes, dans la position fermée et lorsque le module 2 est reçu sur l'interface 10 l'appareil 1, les crochets 24 sont engagés dans les rainures 16, ce qui empêche le retrait du module 2. Dans la position ouverte, les crochets 24 sont libérés des rainures 16.In other words, in the closed position and when the module 2 is received on the interface 10 of the device 1, the hooks 24 are engaged in the grooves 16, which prevents the withdrawal of the module 2. In the open position , the hooks 24 are released from the grooves 16.

Les crochets 24 sont ici ménagés sur des faces latérales du boîtier 20, près de la face du boîtier 20 qui est tournée vers la face 13 lorsque le module 2 est connecté avec l'appareil 1. Les crochets 24 sont ici disposés symétriquement de part et d'autre du boîtier 20 par rapport à un plan vertical du module 2.The hooks 24 are here provided on the lateral faces of the housing 20, near the face of the housing 20 which is turned towards the face 13 when the module 2 is connected with the device 1. The hooks 24 are here arranged symmetrically on both sides. the other of the box 20 with respect to a vertical plane of the module 2.

Par exemple, les crochets 24 sont ménagés d'un seul tenant avec le reste du boîtier 20. Chaque crochet 24 est relié au reste du boîtier 20 par une portion de matière formant une charnière autorisant le pivotement élastique du crochet 24, en étant par ailleurs séparé du reste du boîtier 20 par une découpe.For example, the hooks 24 are made in one piece with the rest of the housing 20. Each hook 24 is connected to the rest of the housing 20 by a portion of material. forming a hinge allowing elastic pivoting of the hook 24, being furthermore separated from the rest of the housing 20 by a cutout.

Les crochets 24 sont adaptés pour être déplacés depuis leur position fermée vers leur position ouverte en déplaçant le bouton 23 de sa position de repos vers sa position appuyée. En d'autres termes, les crochets 24 sont actionnables grâce au bouton 23.The hooks 24 are adapted to be moved from their closed position to their open position by moving the button 23 from its rest position to its pressed position. In other words, the hooks 24 are operable thanks to the button 23.

De préférence, chaque crochet 24 comporte une came 241, disposée de manière à ce qu'un effort exercé sur la came 241 parallèlement à l'axe X2 entraîne un déplacement du crochet 24 vers sa position ouverte. Le bouton 23 comporte à cet effet des portions d'appui additionnelles 232, solidaires avec le corps du bouton 23, et destinées à pousser sur les cames 241 lorsque le bouton 23 est déplacé vers sa position appuyée.Preferably, each hook 24 comprises a cam 241, arranged so that a force exerted on the cam 241 parallel to the axis X2 causes a displacement of the hook 24 towards its open position. The button 23 comprises for this purpose additional support portions 232, integral with the body of the button 23, and intended to push on the cams 241 when the button 23 is moved to its pressed position.

Un exemple d'utilisation du module 2 est maintenant décrit aux figures 4 à 8.An example of using module 2 is now described in figures 4 to 8 .

Initialement, le module 2 est dans une position déconnectée, comme illustré sur la figure 4. Les lames 12 sont dans la position relâchée. Le bouton 23 est dans sa position de repos. Les liaisons 3 sont déjà connectées aux pièces 21 du module 2.Initially, module 2 is in a disconnected position, as shown in the figure 4 . The blades 12 are in the released position. Button 23 is in its rest position. Links 3 are already connected to parts 21 of module 2.

Le module 2 est ensuite rapproché de l'interface 10 jusqu'à entrer en contact avec la face 13, comme illustré sur les figures 5 et 7.Module 2 is then brought closer to interface 10 until it comes into contact with face 13, as illustrated in the figures 5 and 7 .

Ce faisant, les portions de raccordement 212 traversent les fentes 14 et entrent en contact avec les contacts électriques 11, établissant ainsi un contact électrique entre les contacts 11 et les liaisons 3.In doing so, the connection portions 212 pass through the slots 14 and come into contact with the electrical contacts 11, thus establishing an electrical contact between the contacts 11 and the connections 3.

Les lames 12 sont légèrement déplacées par les portions de raccordement 212 puis reviennent dans leur position relâchée, où elles appuient sur les portions de raccordement 212, pour favoriser le contact des portions de raccordement 212 avec les contacts électriques 11 et s'opposer à leur retrait.The blades 12 are moved slightly by the connection portions 212 then return to their released position, where they press on the connection portions 212, to promote contact of the connection portions 212 with the electrical contacts 11 and to oppose their withdrawal .

En pratique, les lames 12 peuvent ne pas revenir rigoureusement à leur position initiale, quand bien même elles sont relâchées, ceci du fait de la présence de la ou des portion(s) de raccordement 212, comme illustré sur la figure 4. Toutefois, les lames 12 sont alors dans une position qui ne s'écarte de la position relâchée que de façon minime, et qui de surcroît est différente de la position enfoncée.In practice, the blades 12 may not return rigorously to their initial position, even though they are released, this due to the presence of the connection portion (s) 212, as illustrated in FIG. figure 4 . However, the blades 12 are then in a position which deviates from the relaxed position only minimally, and which in addition is different from the depressed position.

Lorsque les crans 214 sont présents sur les portions de raccordement 212, ils forment des butées qui coopèrent avec l'extrémité libre de la lame 12 correspondante pour s'opposer encore plus au retrait de la portion de raccordement 212 lorsque la lame 12 est dans sa position relâchée.When the notches 214 are present on the connection portions 212, they form stops which cooperate with the free end of the corresponding blade 12 to further oppose the withdrawal of the connection portion 212 when the blade 12 is in its position. relaxed position.

Simultanément, les portions d'appui 231 peuvent passent au travers des fentes 15 mais, à ce stade, ils n'appuient pas sur les lames 12 puisque le bouton 23 est dans la position de repos.Simultaneously, the bearing portions 231 can pass through the slots 15 but, at this stage, they do not press on the blades 12 since the button 23 is in the rest position.

En parallèle, les crochets 24 viennent s'enclencher dans les rainures 16 et reviennent élastiquement vers leur position fermée, pour verrouiller le module 2 sur l'appareil 1. Là encore, les portions 232 n'appuient pas sur les cames 241 puisque le bouton 23 est dans la position de repos.In parallel, the hooks 24 engage in the grooves 16 and return elastically to their closed position, to lock the module 2 on the device 1. Here again, the portions 232 do not press on the cams 241 since the button 23 is in the rest position.

Pour déconnecter le module 2 de l'appareil 1, une pression est exercée sur le poussoir 233 pour déplacer le bouton 23 vers la position appuyée, comme illustré par la flèche F1 sur les figures 6 et 8. Ce faisant, les portions d'appui 231 entrent en contact avec les lames 12 et les déplacent vers leur position enfoncée pour qu'elles libèrent les portions de raccordement 212.To disconnect module 2 from device 1, pressure is exerted on push-button 233 to move button 23 to the pressed position, as illustrated by arrow F1 on the figures 6 and 8 . In doing so, the bearing portions 231 come into contact with the blades 12 and move them to their depressed position so that they release the connecting portions 212.

Simultanément, sous l'effet du déplacement du bouton 23, les portions d'appui additionnelles 232 poussent les cames 241, ce qui fait pivoter les crochets 24 vers leur position ouverte, comme illustré par les flèches F2 et F2' sur la figure 8.Simultaneously, under the effect of the displacement of the button 23, the additional support portions 232 push the cams 241, which causes the hooks 24 to pivot towards their open position, as illustrated by the arrows F2 and F2 'on the figure. figure 8 .

Le module 2 est déverrouillé et peut être retiré de l'appareil 1. Si le bouton 23 est biaisé élastiquement, il peut être nécessaire de maintenir un appui sur le bouton 23 pendant le retrait de du module 2.Module 2 is unlocked and can be removed from device 1. If button 23 is resiliently biased, it may be necessary to keep button 23 pressed while removing module 2.

Selon des variantes, le déplacement du module 2 n'est pas nécessairement en translation selon l'axe X2, mais plutôt selon un axe géométrique incliné par rapport à la face 13. Dans ce cas, l'agencement des pièces 21 et du bouton 23 sont adaptées en conséquence, par exemple en inclinant les portions 212 et la trajectoire du bouton 23 est selon cet axe.According to variants, the movement of the module 2 is not necessarily in translation along the axis X2, but rather along a geometric axis inclined relative to the face 13. In this case, the arrangement of the parts 21 and of the button 23 are adapted accordingly, for example by tilting the portions 212 and the trajectory of the button 23 is along this axis.

L'utilisation d'un module 2 interchangeable distinct de l'appareil 1 permet de simplifier la fabrication à l'échelle industrielle de l'appareil 1 et aussi d'offrir une plus grande souplesse d'utilisation. En effet, au lieu de devoir fabriquer autant de variantes d'appareil électrique qu'il existe de possibilités de connecter les liaisons 3, on peut fabriquer un appareil 1 pourvu d'une interface 10 de raccordement standardisée, et des modules 2 chacun adapté à un type de raccordement, étant entendu qu'un module 2 est moins complexe et moins onéreux à fabriquer que l'appareil 1.The use of an interchangeable module 2 separate from the device 1 makes it possible to simplify the manufacture on an industrial scale of the device 1 and also to offer greater flexibility of use. Indeed, instead of having to manufacture as many variants of electrical device as there are possibilities of connecting the links 3, it is possible to manufacture a device 1 provided with a standardized connection interface 10, and modules 2 each adapted to a type of connection, it being understood that a module 2 is less complex and less expensive to manufacture than the device 1.

La déconnexion du module 2, à la fois électriquement et mécaniquement, est permise par simple pression sur le bouton 23, et peut être réalisée sans avoir besoin d'outillages complexes, ce qui offre une plus grande souplesse d'utilisation.The disconnection of the module 2, both electrically and mechanically, is permitted by simply pressing the button 23, and can be carried out without the need for complex tools, which offers greater flexibility of use.

Le module 2 permet également de conserver l'agencement des connexions des liaisons 3 lorsque l'appareil 1 doit être temporairement déconnecté de l'installation électrique, par exemple lors d'opérations de maintenance. L'utilisateur n'est pas obligé de déconnecter une à une toutes les liaisons 3 pour, ensuite, les reconnecter une à une lorsqu'il a terminé, avec le risque de se tromper en les reconnectant. Au contraire, grâce à l'invention, pour déconnecter l'appareil 1 de l'installation électrique, il suffit de déconnecter le module 2 de l'appareil 1. Les liaisons 3 n'ont pas besoin d'être déconnectées du module 2. Cela permet là aussi une plus grande souplesse d'utilisation.Module 2 also makes it possible to keep the arrangement of the connections of links 3 when device 1 must be temporarily disconnected from the installation. electrical, for example during maintenance operations. The user is not obliged to disconnect all the links 3 one by one in order to then reconnect them one by one when he has finished, with the risk of making a mistake in reconnecting them. On the contrary, thanks to the invention, to disconnect the device 1 from the electrical installation, it suffices to disconnect the module 2 from the device 1. The links 3 do not need to be disconnected from the module 2. This also allows greater flexibility of use.

Enfin, l'invention permet d'obtenir une connexion mécanique améliorée. En particulier, le dispositif de verrouillage limite le risque de déconnexion accidentelle du module 2.Finally, the invention makes it possible to obtain an improved mechanical connection. In particular, the locking device limits the risk of accidental disconnection of module 2.

Les modes de réalisation et les variantes envisagés ci-dessus peuvent être combinés entre eux pour générer de nouveaux modes de réalisation.The embodiments and the variants considered above can be combined with one another to generate new embodiments.
