Description

L'invention concerne une pince de contact électrique, et un dispositif à pince pourvu d'une telle pince.The invention relates to an electrical contact clamp, and to a clamp device provided with such a clamp.

L'invention concerne en particulier une pince de contact et un dispositif à pince destinés notamment à être montés sur les pôles des disjoncteurs sectionneurs à mouvement rotatif.The invention relates in particular to a contact clamp and a clamp device intended in particular to be mounted on the poles of circuit breaker disconnectors with rotary movement.

On connaît des pinces de connexion comprenant un corps de pince définissant un plan longitudinal de pincement, une première série de doigts de contact montée longitudinalement sur le corps de pince, d'un côté du plan de pincement, et une deuxième série de doigt de contact montée longitudinalement sur le corps de pince, de l'autre côté du plan de pincement, en regard de la première série. Chaque doigt de contact a une face frontale en regard du plan de pincement, une face dorsale opposée à la face frontale, une première et une deuxième extrémités frontales en regard du plan de pincement. Les dites première et deuxième séries définissent une première mâchoire entre les premières extrémités frontales des doigts de contact en regard, et une deuxième mâchoire entre les deuxièmes extrémités frontales des doigts de contact en regard. Les premières extrémités de chaque série sont liées ensemble par un axe longitudinal, l'écartement entre chaque extrémité d'une même série étant maintenu par des entretoises portées par ledit axe. Les deuxièmes extrémités de chaque série sont elles aussi liées par un axe longitudinal. Cet axe est en outre associé au corps de pince par une association à jeu radial pour permettre le mouvement des deuxièmes extrémités par rapport au corps de pinces. L'écartement entre chaque deuxième extrémité d'une même série est aussi maintenu par des entretoises portées par l'axe. L'écartement entre deux doigts en vis à vis est obtenu par une entretoise transversale. L'élasticité de la pince est obtenue par un ressort hélicoïdal tendu entre deux doigts en vis à vis. Une telle pince fait partie d'un dispositif de pince. Ce dispositif comprend, outre la pince, un support sur lequel le corps de pince est monté rigidement, la deuxième mâchoire enserrant ledit support. Le but de ce dispositif est que la première mâchoire vienne s'enserrer, par pivotement autour d'un axe perpendiculaire au plan de pincement, sur une barre conductrice afin d'assurer le passage d'un courant électrique entre le support et la barre.Connection clamps are known comprising a clamp body defining a longitudinal pinch plane, a first series of contact fingers mounted longitudinally on the clamp body, on one side of the pinch plane, and a second series of contact fingers mounted longitudinally on the clamp body, on the other side of the clamping plane, opposite the first series. Each contact finger has a front face facing the pinch plane, a dorsal face opposite the front face, first and second front ends facing the pinch plane. Said first and second series define a first jaw between the first front ends of the facing contact fingers, and a second jaw between the second front ends of the facing contact fingers. The first ends of each series are linked together by a longitudinal axis, the spacing between each end of the same series being maintained by spacers carried by said axis. The second ends of each series are also linked by a longitudinal axis. This axis is also associated with the gripper body by an association with radial clearance to allow the movement of the second ends relative to the gripper body. The spacing between each second end of the same series is also maintained by spacers carried by the axis. The spacing between two opposite fingers is obtained by a spacer transverse. The elasticity of the clamp is obtained by a helical spring stretched between two fingers opposite. Such a clamp is part of a clamp device. This device comprises, in addition to the clamp, a support on which the clamp body is rigidly mounted, the second jaw enclosing said support. The purpose of this device is that the first jaw is clamped, by pivoting about an axis perpendicular to the pinch plane, on a conductive bar to ensure the passage of an electric current between the support and the bar.

La pince et le dispositif de pince décrits ci-dessus ont des inconvénients, à savoir :

  • le nombre important de pièces constitutives de la pince. En effet pour le montage d'une pince ayant des séries de six doigts de contact il faut au minimum, une vingtaine d'entretoises axiales, trois entretoises transversales (une pour quatre doigts), trois ressorts à boudin (un pour quatre doigts) et leurs points d'appui, quatre axes longitudinaux.
  • le fait que les doigts d'une même série sont montés solidaires les uns avec les autres par l'intermédiaire des axes longitudinaux induit un mouvement d'ensemble des extrémités. Ainsi si la barre conductrice présente une déviation axiale telle qu'elle ne soit pas dans le plan de pincement, une partie des extrémités ne pourront être au contact de la barre puisqu'elles sont contraintes à un alignement suivant les axes longitudinaux.
  • le fait que le corps de pince soit monté rigidement sur le support n'autorise aucune inclinaison de la pince par rapport au support. De ce fait, si la barre n'est pas exactement comprise dans le plan de pincement, celle-ci ne peut pénétrer dans la première mâchoire.
The clamp and the clamp device described above have drawbacks, namely:
  • the large number of constituent parts of the clamp. Indeed, for mounting a clamp having a series of six contact fingers, at least twenty axial spacers, three transverse spacers (one for four fingers), three coil springs (one for four fingers) and their support points, four longitudinal axes.
  • the fact that the fingers of the same series are mounted integral with each other via the longitudinal axes induces an overall movement of the ends. Thus if the conductive bar has an axial deviation such that it is not in the pinch plane, part of the ends cannot be in contact with the bar since they are forced to be aligned along the longitudinal axes.
  • the fact that the clamp body is rigidly mounted on the support does not allow any inclination of the clamp relative to the support. Therefore, if the bar is not exactly included in the clamping plane, it can not enter the first jaw.

Un premier but de la présente invention est de proposer une pince comprenant un nombre de pièces limité, de montage aisé.A first object of the present invention is to propose a clamp comprising a limited number of parts, of easy assembly.

Un autre but de la présente invention est de fournir une pince où les doigts sont montés indépendants les uns des autres, de sorte que chaque doigt de contact ait son propre mouvement de pincement.Another object of the present invention is to provide a clamp where the fingers are mounted independent of each other others, so that each contact finger has its own pinch movement.

Un autre but de la présente invention est d'articuler le corps de pince sur le support de manière à ce que la barre puisse pénétrer dans la première mâchoire même si elle n'est pas exactement comprise dans le plan de pincement initial.Another object of the present invention is to articulate the gripper body on the support so that the bar can penetrate the first jaw even if it is not exactly included in the initial gripping plane.

Un autre but de la présente invention est de fournir une extrémité de doigt de contact en forme de cuillère présentant un bord d'attaque arrondi dans toutes les directions et notamment dans celle de l'axe longitudinal de la pince.Another object of the present invention is to provide a spoon-shaped contact finger end having a leading edge rounded in all directions and in particular in that of the longitudinal axis of the clamp.

A cet effet l'invention concerne une pince de connexion comprenant un corps de pince définissant un plan longitudinal de pincement, une première série de doigts de contact montés longitudinalement sur le corps de pince, d'un côté du plan de pincement, et une deuxième série de doigt de contact montés longitudinalement sur le corps de pince, de l'autre côté du plan de pincement, en regard de la première série, Chaque doigt de contact ayant une face frontale en regard du plan de pincement, une face dorsale opposée à la face frontale, une première et une deuxième extrémités frontales en regard du plan de pincement, les dites première et deuxième séries définissant une première mâchoire entre les premières extrémités frontales des doigts de contact en regard, et une deuxième mâchoire entre les deuxièmes extrémités frontales des doigts de contact en regard.To this end, the invention relates to a connection clamp comprising a clamp body defining a longitudinal clamping plane, a first series of contact fingers mounted longitudinally on the clamp body, on one side of the clamping plane, and a second series of contact fingers mounted longitudinally on the clamp body, on the other side of the pinch plane, facing the first series, Each contact finger having a front face opposite the pinch plane, a dorsal face opposite to the front face, first and second front ends facing the pinch plane, said first and second series defining a first jaw between the first front ends of the contact fingers facing each other, and a second jaw between the second front ends of the contact fingers facing.

Selon l'invention chaque doigt de la première et de la deuxième séries monté sur ledit corps de pince, est mobile indépendamment des autres doigts.According to the invention each finger of the first and second series mounted on said clamp body, is movable independently of the other fingers.

La pince comprend un élément de blocage frontal sur lequel porte une zone centrale frontale de la face frontale du doigt, et un élément d'appui dorsal sur lequel porte une zone centrale dorsale de la face dorsale du doigt.The clamp comprises a front locking element on which bears a central front region of the front face of the finger, and a dorsal support element on which carries a central dorsal region of the dorsal face of the finger.

Au moins une des zones frontale ou dorsale porte sur respectivement l'élément de blocage ou d'appui par l'intermédiaire d'un élément élastique.At least one of the front or back areas bears respectively on the blocking or support element by means of an elastic element.

Selon une forme de réalisation de l'invention, le corps de pince comprend deux extrémités transversales de forme générale en "U", couplée l'une à l'autre par au moins deux montants longitudinaux en regard, chaque montant comprenant une pluralité d'alvéoles d'accueil des doigts de contact, chacune des alvéoles ayant un fond et deux parois latérales, chaque doigt de contact comprenant un passage central ou équivalent ajusté à la largeur entre les parois latérales des alvéoles d'accueil, des agrafes longitudinales de maintien étant montées sur le corps de pince parallèlement aux montants transversaux, bloquant les faces libres des doigts montés dans lesdites alvéoles. Avantageusement le corps de pince est monobloc. Les alvéoles, localisées sur les faces en regard des montants transversaux, forment lesdits éléments d'appui dorsal, et lesdites agrafes, bloquant les faces frontales des doigts de contact, forment les éléments de blocage frontal.According to one embodiment of the invention, the clamp body comprises two transverse ends of general "U" shape, coupled to each other by at least two facing longitudinal uprights, each upright comprising a plurality of cells for receiving the contact fingers, each of the cells having a bottom and two side walls, each contact finger comprising a central passage or equivalent adjusted to the width between the side walls of the cells of reception, longitudinal holding clips being mounted on the clamp body parallel to the transverse uprights, blocking the free faces of the fingers mounted in said cells. Advantageously, the clamp body is in one piece. The cells, located on the opposite faces of the transverse uprights, form said back support elements, and said clips, blocking the front faces of the contact fingers, form the front blocking elements.

L'élément élastique est une lame élastique intercalée entre le fond de l'alvéole et la face dorsale du doigt de contact associé. La lame élastique a une forme générale en "U", et le doigt de contact a des extrémités dorsales creusées, logeant les extrémités libres de la lame élastique en forme de "U", la branche centrale de la lame élastique étant au contact du fond de l'alvéole.The elastic element is an elastic blade inserted between the bottom of the cell and the dorsal face of the associated contact finger. The elastic blade has a general "U" shape, and the contact finger has hollowed back ends, accommodating the free ends of the elastic blade in a "U" shape, the central branch of the elastic blade being in contact with the bottom. of the socket.

La pince comprend une agrafe longitudinale par montant longitudinal, ayant une partie centrale longitudinale bloquant les doigts de contact, et deux parties extrêmes encliquetable sur ou dans les extrémités transversales.The clamp comprises a longitudinal clip by longitudinal post, having a longitudinal central part blocking the contact fingers, and two end parts snap-on on or in the transverse ends.

En position prête à être associée, la pince comprend un outil prétendeur, précontaignant les éléments élastiques pour ouvrir la mâchoire destinée à enserrer le support.In the position ready to be combined, the clamp comprises a pretensioner tool, pre-tensioning the elastic elements to open the jaw intended to grip the support.

L'invention concerne aussi un dispositif à pince de connexion comprenant un support conducteur, et une pince de connexion ayant un corps de pince définissant un plan longitudinal de pincement, une première série de doigts de contact montée longitudinalement sur le corps de pince, d'un côté du plan de pincement, et une deuxième série de doigt de contact montée longitudinalement sur le corps de pince, de l'autre côté du plan de pincement, en regard de la première série, Chaque doigt de contact ayant une face frontale en regard du plan de pincement, une face dorsale opposée à la face frontal, une première et une deuxième extrémités frontales en regard du plan de pincement, les dites première et deuxième séries définissant une premier mâchoire entre les premiers extrémités frontales des doigts de contact en regard, et une deuxième mâchoire entre les deuxièmes extrémités frontales des doigts de contact en regard, ledit corps de pince étant solidarisé au support, l'une des mâchoires enserrant le support. Selon l'invention, le dispositif comprend des moyens d'association du corps de pince sur le support pour que le corps de pince soit libre de basculer autour d'un axe de basculement longitudinal par rapport au support.The invention also relates to a connection clamp device comprising a conductive support, and a connection clamp having a clamp body defining a longitudinal pinching plane, a first series of contact fingers mounted longitudinally on the clamp body, one side of the pinch plane, and a second series of contact fingers mounted longitudinally on the clamp body, on the other side of the pinch plane, facing the first series, each contact finger having a facing front face of the pinch plane, a dorsal face opposite the front face, first and second front ends facing the pinch plane, said first and second series defining a first jaw between the first front ends of the contact fingers facing, and a second jaw between the second front ends of the facing contact fingers, said clamp body being secured to the sup port, one of the jaws enclosing the support. According to the invention, the device comprises means for associating the gripper body on the support so that the gripper body is free to tilt around an axis of longitudinal tilting relative to the support.

Avec une pince selon le mode de réalisation de l'invention les branches transversales des deux extrémités transversales en forme de "U" recouvrent les extrémités transversales du support, un axe longitudinal de basculement passant au travers des dites branches transversales et du support.With pliers according to the embodiment of the invention, the transverse branches of the two transverse ends in the shape of a "U" cover the transverse ends of the support, a longitudinal tilting axis passing through said transverse branches and of the support.

Les avantages d'une telle pince et d'un tel dispositif à pince sont notamment :

  • une simplification sensible du montage de la pince due a une diminution des pièces constitutive;
  • une facilité de montage due au fait que toutes les pièces élastiques sont montées détendues, et ne sont contrainte que dans l'étape postérieure où la pince est mise en position prête à être utilisée;
  • chaque doigt a son propre mouvement de pincement indépendant des autres doigts;
  • un montage basculant du corps de pince sur le support.
The advantages of such a clamp and of such a clamp device are in particular:
  • a significant simplification of the assembly of the clamp due to a reduction in the constituent parts;
  • ease of assembly due to the fact that all of the elastic parts are mounted relaxed, and are only constrained in the later stage where the clamp is placed in the position ready for use;
  • each finger has its own pinch movement independent of the other fingers;
  • a tilting mounting of the clamp body on the support.

La lame élastique 13 a une forme générale en "U". Les extrémités libres 22 de la lame élastique 13 en forme de "U" viennent se logées dans des parties creuses dorsales des extrémités des doigts de contact 5, la branche centrale 23 de la lame élastique 13 étant au contact du fond 20 de l'alvéole 16.The elastic blade 13 has a general "U" shape. The free ends 22 of the elastic blade 13 in the shape of a "U" are housed in hollow dorsal parts of the ends of the contact fingers 5, the central branch 23 of the elastic blade 13 being in contact with the bottom 20 of the cell 16.

La pince comprend une agrafe longitudinale 19 par montant longitudinal 15. Chaque agrafe 19 a une partie centrale longitudinale 24 bloquant les doigts de contact 5, et deux parties extrêmes 25 encliquetables sur ou dans les extrémités transversales 14. La partie centrale longitudinale 24 de l'agrafe 19 est positionnée entre les premières extrémités 8a des doigts de contact 5 et les montants longitudinaux 15. Avantageusement, le système d'encliquetage vient de moulage avec le corps de pince monobloc. Dans la forme de réalisation représentée sur la figure 2, le système d'encliquetage est du type à chicane, la partie extrême 25 vient s'enrouler d'un quart de tour autour d'un plot 52 d'axe longitudinal localisé sur la face externe des extrémités transversales 14, l'extrémité libre 53 de ladite partie extrême 25 venant se bloquer contre une butée 54 en opposition avec le plot 52.The clamp comprises a longitudinal clip 19 per longitudinal post 15.

Sur la figure 1, la pince est représentée en position de repos. C'est ainsi que la pince est confectionnée, sans aucune pièce élastique précontrainte, ce qui facilite sensiblement l'étape de montage.In Figure 1, the clamp is shown in the rest position. This is how the clamp is made, without any elastic prestressed part, which considerably facilitates the assembly step.

Sur les figures 2 à 5, la pince est représentée en position prête à l'emploi. Dans cette position, il a été introduit un outil prétendeur 26, précontraignant les lames élastiques 13, de manière que la deuxième mâchoire 9b soit ouverte, prête à enserrer le support sur lequel la pince sera associée. Cet outil 26 est positionné entre les deux séries de doigts de contact 5, entre les deuxièmes extrémités 8b des doigts de contact 5 et les montants longitudinaux 15. Dans le mode de réalisation représenté sur les figures, l'outil 26, repose sur la branche centrale de la forme en "U" des extrémités transversales 14. L'outil 26 est un fil de section circulaire cintré en forme de rectangle, venant se clipser dans des formes aménagées à l'intersection des branches libres avec la branche centrale des extrémités transversales en forme de "U".In Figures 2 to 5, the clamp is shown in the ready to use position. In this position, a pretensioner tool 26 has been introduced, prestressing the elastic blades 13, so that the second jaw 9b is open, ready to grip the support on which the clamp will be associated. This tool 26 is positioned between the two series of contact fingers 5, between the second ends 8b of the contact fingers 5 and the longitudinal uprights 15. In the embodiment shown in the figures, the tool 26 rests on the branch center of the "U" shape of the transverse ends 14. The tool 26 is a circular section wire bent in the shape of a rectangle, which clips into shapes arranged at the intersection of the free branches with the central branch of the transverse ends "U" shaped.

L'invention concerne aussi un dispositif à pince de connexion comprenant un support conducteur 30, et une pince de connexion 1 telle que décrite ci-dessus. Le corps de pince 2 est associé au support 30, la deuxième mâchoire 9b enserrant le support. Le corps de pince 2 et le support sont associés par des moyens d'association tels que le corps de pince 2 soit libre de basculer par rapport au support 30 autour d'un axe de basculement longitudinal 31.The invention also relates to a connection clamp device comprising a conductive support 30, and a connection clamp 1 as described above. The clamp body 2 is associated with the support 30, the second jaw 9b enclosing the support. The gripper body 2 and the support are associated by association means such that the gripper body 2 is free to tilt relative to the support 30 about a longitudinal tilting axis 31.

Selon les représentations des figures les moyens d'association comprennent les branches centrales des extrémités transversales 14 en forme de "U", chacune pourvue d'un trou circulaire 32 de même axe, un alésage longitudinal 33 traversant de part en part le support 30, et un axe 31. La deuxième mâchoire 9b enserre le support 30, les branches centrales des extrémités transversales 14 en forme de "U" venant en recouvrement des extrémités transversales du support 30, les trous viennent en regard de alésage, l'axe longitudinal de basculement passant au travers desdits trous et dudit alésage.According to the representations of the figures, the association means comprise the central branches of the transverse ends 14 in the shape of a "U", each provided with a circular hole 32 of the same axis, a longitudinal bore 33 passing right through the support 30, and an axis 31. The second jaw 9b encloses the support 30, the central branches of the transverse ends 14 in the shape of a "U" coming to overlap the transverse ends of the support 30, the holes come opposite the bore, the longitudinal tilt axis passing through said holes and said bore.

Selon l'invention, la pince, en fin de confection, a l'aspect de la figure 1.According to the invention, the clip, at the end of making, has the appearance of FIG. 1.

La pince est livrée prête à l'emploi sous l'aspect représenté sur les figures 2 à 5.The pliers are delivered ready to use in the appearance shown in Figures 2 to 5.

La figure 6 représente le dispositif selon l'invention, la pince étant associée sur le support.FIG. 6 represents the device according to the invention, the clamp being associated on the support.

La figure 7 représente le dispositif en position enclenchée normale, c'est à dire lorsque la barre 36 est dans le même plan que le support 30.FIG. 7 shows the device in the normal engaged position, that is to say when the bar 36 is in the same plane as the support 30.

La figure 8 représente le dispositif en position enclenchée avec basculement, c'est à dire lorsque la pince bascule pour rattraper le jeu existant entre le plan de la barre 36 et le plan du support 30.FIG. 8 shows the device in the engaged position with tilting, that is to say when the clamp rocks to catch up with the play existing between the plane of the bar 36 and the plane of the support 30.

Dans les deux dernières configurations (fig. 7 et 8) les doigts de contact sont bien positionnés sur le support 30 et sur la barre 36 grâce à la compression des lames élastiques 13.In the last two configurations (fig. 7 and 8) the contact fingers are well positioned on the support 30 and on the bar 36 thanks to the compression of the elastic blades 13.

Ce type de dispositif à pince trouve notamment son application dans des disjoncteurs sectionneurs passant d'une position active à une position passive par rotation. Les pôles des disjoncteurs sectionneurs sont pourvus de dispositif selon l'invention, de telle manière que lors de la rotation des disjoncteurs sectionneurs, les pinces viennent s'enclencher sur les barres conductrices.This type of clamp device finds its application in particular in circuit breakers disconnecting from an active position to a passive position by rotation. The poles of the disconnecting circuit breakers are provided with a device according to the invention, so that when the disconnecting circuit breakers rotate, the clamps engage on the busbars.

Les avantages d'une telle pince et d'un tel dispositif à pince sont notamment :

  • une simplification sensible du montage de la pince due a une diminution des pièces constitutive;
  • une facilité de montage due au fait que toutes les pièces élastiques sont montées détendues, et ne sont contraintes que dans l'étape postérieure où la pince est mise en position prête à être utilisée;
  • chaque doigt a son propre mouvement de pincement indépendant des autres doigts;
  • la forme en cuillère des extrémités des doigts de contact au moins du côté de la première mâchoire, permet de présenter un bord d'attaque favorable à l'enserrage;
  • un montage pivotant du corps de pince sur le support.
The advantages of such a clamp and of such a clamp device are in particular:
  • a significant simplification of the assembly of the clamp due to a reduction in the constituent parts;
  • ease of assembly due to the fact that all of the elastic parts are mounted relaxed, and are only constrained in the subsequent step where the clamp is placed in the position ready for use;
  • each finger has its own pinch movement independent of the other fingers;
  • the spoon shape of the ends of the contact fingers at least on the side of the first jaw, makes it possible to present a leading edge favorable to clamping;
  • a pivoting mounting of the clamp body on the support.

Bien que seul un mode de réalisation ait été décrit, il est clair que toute modification qui serait évidente pour l'homme du métier est comprise dans le cadre de la présente l'invention.Although only one embodiment has been described, it is clear that any modification which would be obvious to a person skilled in the art is included within the scope of the present invention.
