Description

La présente invention concerne un dispositif de connexion qui comprend au moins une borne du type présentant une cage élastique et une pièce conductrice ce courant, celle-ci assurant la fonction de support pour la cage.The present invention relates to a connection device which comprises at least one terminal of the type having an elastic cage and a conductive part that current, the latter providing the support function for the cage.

Les dispositifs de connexion de ce type sont bien connus par exemple du Document DE 3911459. Ils sont associés a un appareil ou organe électrique et permettent de serrer dans la borne un câble à connecter à l'appareil ou à l'organe sans devoir recourir à une vis de serrage. De manière usuelle, la cage élastique est posée près d'une extrémité de la pièce de support proche d'une face d'accès de l'appareil et comporte une aile d'appui appliquée sur la pièce de support, une aile de serrage dotée d'une fenêtre de serrage de conducteur par effet de coincement et une boucle reliant l'aile d'appui à l'aile de serrage et formant ressort pour assurer le coincement du conducteur.Connection devices of this type are well known, for example from DE 3911459. They are associated with an apparatus or electrical member and allow to tighten in the terminal a cable to connect to the device or the body without having to resort to a clamping screw. In the usual manner, the elastic cage is placed near one end of the support piece close to an access face of the apparatus and comprises a support wing applied to the support piece, a clamping wing equipped with a wedging clamping conductor window and a loop connecting the support wing to the clamping wing and forming a spring to secure the driver.

Dans certains appareils électriques comprenant de telles bornes de connexion élastique, il est souhaitable de pouvoir établir une connexion, non seulement avec des câbles rapportés et maintenus par coincement, mais aussi avec des barres d'alimentation ou avec d'autres appareils disposés latéralement ou en superposition, en bénéficiant de l'existence des bornes en question.In some electrical devices comprising such elastic connection terminals, it is desirable to be able to establish a connection, not only with cables reported and maintained by wedging, but also with power bars or with other devices arranged laterally or in superposition, benefiting from the existence of the terminals in question.

L'invention a ainsi pour but de tirer parti des bornes à cage élastique prévues dans un appareil électrique pour assurer la connexion d'un câble, afin de réaliser une liaison simple et fiable avec un autre appareil ou avec un organe conducteur de courant.The object of the invention is therefore to take advantage of the elastic cage terminals provided in an electrical appliance for connecting a cable, in order to make a simple and reliable connection with another appliance or with a current-conducting member.

Selon l'invention, le dispositif de connexion présente un bloc isolant qui porte d'une part une branche propre à assurer l'ouverture de la cage élastique et d'autre part une branche conductrice de connexion, les deux branches étant dirigées de manière sensiblement parallèle à l'aile d'appui de la cage et agencées de façon que lorsque le bloc accoste la cage, la branche d'ouverture fléchit la boucle pour permettre l'introduction de la branche de connexion dans la fenêtre de serrageAccording to the invention, the connection device has an insulating block which carries, on the one hand, a branch capable of ensuring the opening of the elastic cage and, on the other hand, a conductive connection branch, the two branches being directed substantially parallel to the support wing of the cage and arranged so that when the block docked the cage, the opening branch flexed the loop to allow the introduction of the connecting branch in the tightening window

De préférence, les deux branches sont rigides et un espace subsiste en position serrée entre la branche d'ouverture et son logement dans la directicn de détente de la boucle élastique de manière que la pression d'application de la branche de connexion sur la pièce conductrice soit due à !a pression exercée par la boucle sur la branche d'ouverture. L'une des branches peut être dotée d'une forme contribuant à retenir le bloc en position connectée. Le corps isolant présente d'autre part au moins un élément d'interconnexion tel qu'une broche conductrice parallèle à la branche de connexion et reliée à celle-ci pour assurer la liaison avec un autre appareil.Preferably, the two branches are rigid and a space remains in a tight position between the opening branch and its housing in the expansion direction of the elastic loop so that the application pressure of the connecting branch on the conductive part due to the pressure exerted by the loop on the opening branch. One of the branches can be provided with a shape contributing to retain the block in the connected position. The insulating body also has at least one interconnection element such as a conductive pin parallel to the connection branch and connected thereto for connection with another device.

La description est faite ci-après d'un mode de réalisation non limitatif de l'invention, en regard des dessins annexés.The description is made below of a non-limiting embodiment of the invention, with reference to the accompanying drawings.

La figure 1 représente schématiquement un dispositif de connexion conforme à l'invention.Figure 1 schematically shows a connection device according to the invention.

La figure 2 montre en perspective une forme particulière de réalisation du bloc de connexion du dispositif.FIG. 2 shows in perspective a particular embodiment of the connection block of the device.

Les figures 3 et 4 illustrent le dispositif respectivement à l'accostage et à l'état connecté.Figures 3 and 4 illustrate the device respectively docking and the connected state.

L'appareil électrique A dont le contour est représenté en tirets est un appareil électrique de type basse tension à fonction de distribution de commande ou de protection. L'appareil A comprend plusieurs bornes de connexion B de type élastique capables de recevoir et connecter des extrémités de conducteurs C. Le dispositif selon l'invention comporte les bornes B ainsi qu'un bloc -de connexion-D multipolaire le bloc D pourrait bien entendu être aussi unipolaire.The electrical apparatus A whose outline is shown in dashed lines is a low-voltage electrical appliance with a control distribution or protection function. The apparatus A comprises a plurality of elastic-type connection terminals B capable of receiving and connecting the ends of the conductors C. The device according to the invention comprises the terminals B as well as a multipole-D-connection block. heard to be unipolar too.

Chaque borne B comprend une cage élastique 10 et une pièce plate et allongée 20 qui assure la conduction du courant et la fonction de support de la cage. La cage élastique 10 est posée sur le recto 20a de la pièce ce support 20 près d'une extrémité 21 de celle-ci proche d'une paroi d'accès 22 de l'appareil et comporte une aile d'appui 11 appliquée sur la pièce de support sur la longueur de celle-ci, une aile de serrage 12 dotée d'une fenêtre de serrage 13 de conducteur par effet de coincement et une boucle 14 formant ressort et reliant l'aile d'appui 11 à l'aile de serrage 12. Le verso 20b de la pièce 20 sert à la prise de contact avec le câble C et présente à cet effet une bosse 20c.Each terminal B comprises an elastic cage 10 and an elongated flat piece 20 which conducts the current and the support function of the cage. The elastic cage 10 is placed on the front 20a of the part 20 of the support near an end 21 thereof close to an access wall 22 of the apparatus and comprises a support wing 11 applied to the support piece along the length thereof, a clamping wing 12 provided with a wedging clamping window 13 and a spring loop 14 connecting the support wing 11 to the 12. The back 20b of the part 20 is used to make contact with the cable C and has a bump 20c for this purpose.

L'appareil comprend de manière usuelle dans sa paroi d'accès 22 et pour chaque borne B une ouverture 23 d'intreduction pour le câble C à connecter à la pièce 20 et une ouverture 24 servant à engager un outil : comme on le sait, cet outil doit être capable de presser la boucle pour desserrer la borne en permettant de dégager la fenêtre 13 pour y introduire le câble eu l'en dégager. Il convient de noter que la pièce de support 20, l'aile d'appui 11 de la cage élastique 10, les ouvertures 23.24 de la borne sont orientées selon une même direction X qui est celle d'introduction du câble C. La direction Y de détente de la boucle 14 et de déplacement de l'aile 12 est sensiblement perpendicutaire à X. L'ouverture 24 donne accès à un logement 25 contigu à celui de la cage 10 pour que l'outil puisse débattre dans ce logement afin de presser la boucle 14 à l'opposé de la direction Y en prenant appui sur !e bord extérieur 24a de l'ouverture 24.The apparatus comprises conventionally in its access wall 22 and for each terminal B an opening 23 of intreduction for the cable C to connect to the piece 20 and an opening 24 for engaging a tool: as is known, this tool must be able to press the loop to loosen the terminal by allowing the window 13 to be removed to introduce the cable therein. It should be noted that the support piece 20, the support wing 11 of the elastic cage 10, the openings 23.24 of the terminal are oriented in the same direction X which is the introduction of the cable C. The Y direction of relaxation of the loop 14 and displacement of the wing 12 is substantially perpendicular to X. The opening 24 gives access to a housing 25 adjacent to that of the cage 10 so that the tool can debate in this housing to press the loop 14 away from the direction Y by bearing on the outer edge 24a of the opening 24.

Le bloc D possède un corps isolant 30 qui porte d'une part une branche d'ouverture 31 de la cage et d'autre part une branche conductrice de connexion 32. Les deux branches 31,32 sont dirigées de manière sensiblement parallèle à l'aile d'appui 11 de la cage 10 selon X et agencées de façon que lorsque le corps 30 accoste l'appareil A, la branche d'ouverture 31 fléchit la boucle 14 (voir en tirets sur la figure 3) pour permettre l'introduction de la branche de connexion 32 dans la fenêtre 13.Block D has an insulating body 30 which carries on the one hand an opening branch 31 of the cage and on the other hand a connecting conductive branch 32. The two branches 31, 32 are directed substantially parallel to the support wing 11 of the cage 10 along X and arranged so that when the body 30 accosts the apparatus A, the opening branch 31 flexes the loop 14 (see dashed in Figure 3) to allow the introduction of the connection branch 32 in the window 13.

Il convient de noter que les deux branches offrent entre elles un écart prédéterminé h et sont rigides de manière que la pression de contact de la branche de connexion 32 sur la pièce conductrice 20 soit due à la pression exercée par la boucle 14 sur la branche d'ouverture 31. A cet effet, il subsiste en position de serrage de la branche 32 du bloc contre le verso 20b de la pièce 20 de la borne un espace e entre la branche 31 et les surfaces adjacentes de l'ouverture 24, en particulier au niveau de son bord extérieur 24a, et du logement 25. Dans le présent mode d'exécution les deux branches 31,32 sont métalliques et reliées entre elles de manière rigide ; la branche 31 peut aussi être en matériau isolant et éventuellement venir d'une pièce avec le corps 30. La branche de connexion 32 assure la liaison souhaitée de courant entre la pièce 20 et un autre organe ou appareil ; elle peut être reliée dans le corps 30 à une autre fiche ou broche 33 (voir figure 2) qui établit la connexion avec un autre appareil adjacent ou avec un dispositif d'alimentation. La branche 31 présente une pente 31a pour accoster progressivement la boucle 14 et le cas échéant une conformation anti-extraction, par exemple et comme indiqué figure 3 une forme en retrait 31b qui coopère avec la boucle ou un point dur prévu dans un face du logement 25 pour contribuer au maintien du bloc D en position connectée et assemblée sur l'appareil A. La branche 32 présente une pente 32a pour glisser sur le bossage 20c prévue à l'extrémité 21 de la pièce 20 et elle est susceptible d'être appliquée contre le bossage par son bord 32b situé du côté de la branche 31. La branche 32 peut offrir une forme anti-extraction 32c comme indiqué figure 4. Les branches 31,32 ont toute forme appropriée, la branche 31 étant par exemple une fiche plate et la branche 32 une broche ronde.It should be noted that the two branches offer a predetermined distance between them h and are rigid so that the contact pressure of the branch connection 32 on the conductive part 20 is due to the pressure exerted by the loop 14 on the opening branch 31. For this purpose, it remains in the clamping position of the branch 32 of the block against the back 20b of the part 20 of the terminal a space e between the branch 31 and the adjacent surfaces of the opening 24, in particular at its outer edge 24a, and the housing 25. In this embodiment, the two branches 31, 32 are metallic and interconnected rigidly; the branch 31 may also be of insulating material and optionally come from a part with the body 30. The connecting branch 32 provides the desired connection of current between the part 20 and another member or apparatus; it can be connected in the body 30 to another plug or pin 33 (see Figure 2) which establishes the connection with another adjacent device or with a power device. The branch 31 has a slope 31a to gradually dock the loop 14 and optionally an anti-extraction conformation, for example and as shown in Figure 3 a recessed form 31b which cooperates with the loop or a hard point provided in a face of the housing 25 to contribute to the maintenance of the block D in connected and assembled position on the apparatus A. The branch 32 has a slope 32a for sliding on the boss 20c provided at the end 21 of the piece 20 and it is likely to be applied against the boss by its edge 32b located on the side of the branch 31. The branch 32 may provide an anti-extraction form 32c as shown in Figure 4. The branches 31,32 have any suitable shape, the branch 31 being for example a flat plug and branch 32 a round brooch.

Le fonctionnement du dispositif va être décrit en regard des figures 3 et 4.The operation of the device will be described with reference to FIGS. 3 and 4.

L'utilisateur approche le bloc isolant D de l'appareil selon la direction X. En même temps qu'il introduit pour chaque pôle la broche 33 dans une borne ou un organe de connexion non représenté d'un autre appareil ou organe conducteur, il fait pénétrer la branche d'ouverture 31 du bloc D dans l'ouverture 24 de la borne B de l'appareil A ; la pente 31a de la branche 31 s'applique sur l'arrondi frontal de la boucle 14, de sorte que la boucle fléchit : la branche de connexion 12 de la cage 10 vient dans la position indiquée en tirets sur la figure 3 pour rendre accessible la fenêtre 13.The user approaches the insulating block D of the apparatus in the X direction. At the same time as he introduces for each pole the pin 33 into a terminal or a connection member (not shown) of another apparatus or conductive member, he causes the opening branch 31 of the block D to enter the opening 24 of the terminal B of the apparatus A; the slope 31a of the branch 31 is applied to the front rounding of the loop 14, so that the buckle flexes: the connecting branch 12 of the cage 10 comes in the position shown in dashed lines in Figure 3 to make the window 13 accessible.

La poursuite du mouvement d'approche du bloc D entraîne l'introduction de la branche 32 dans la fenêtre 13 et son accostage sur la bosse 20c de la pièce 20, tandis que la branche 31 continue de glisser sur le sommet de la boucle jusqu'à la butée d'un élément du bloc D, par exemple sa face avant 34, contre la face 22 de l'appareil ; on peut observer que le bord 13a de coincement propre à la fenêtre 13, actif pour coincer un câble C, reste inactif vis à vis de !a branche de connexion 32. La branche 32 est maintenue appliquée contre la pièce conductrice 20 par l'effort de réaction de la cage élastique 10 exercé selon la direction Y et transmis par la branche rigide 31 et le corps 30 du bloc D. On notera que le bloc est retenu contre une extraction dans la direction X' par coopération du retrait 31b de la branche 31 avec la boucle 14 ou avec un point dur prévu sur une face du logement 25 ou par coopération du retrait 32c de la branche 32 avec la bosse 2Cc de la pièce conductrice 20. On peut par ailleurs prévoir de manière usuelle un moyen d'accrochage ou d'encliquetage du bloc sur l'appareil.Continuing the approach movement of the block D causes the introduction of the branch 32 in the window 13 and its docking on the hump 20c of the part 20, while the branch 31 continues to slide on the top of the loop until at the stop of an element of the block D, for example its front face 34, against the face 22 of the apparatus; it can be seen that the wedging edge 13a specific to the window 13, which is operative to wedge a cable C, remains inactive with respect to the connection branch 32. The branch 32 is held pressed against the conductive part 20 by the force reaction of the elastic cage 10 exerted in the direction Y and transmitted by the rigid branch 31 and the body 30 of the block D. Note that the block is retained against an extraction in the direction X 'by cooperation withdrawal 31b of the branch 31 with the loop 14 or with a hard point provided on one side of the housing 25 or by cooperation of the withdrawal 32c of the branch 32 with the hump 2Cc of the conductive part 20. It can also be provided in the usual manner a hooking means or snap the block on the device.
