Description

L'invention concerne une pince de contact électrique, et un dispositif à pince pourvu d'une telle pince, selon les préambules des revendications 1 et 14 respectivement, comme il est connu par example du document EP-A-0 451 531.The invention relates to an electrical contact clamp, and a clamp device provided with such a clamp, according to the preambles of claims 1 and 14 respectively, as is known for example from document EP-A-0 451 531.

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 pliers contact and a clamp device intended in particular to be mounted on the poles of the disconnecting circuit breakers rotary movement.

On connaít 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.We know connection clamps comprising a body gripper defining a longitudinal gripping plane, a first series of longitudinally mounted contact fingers on the gripper body, on one side of the gripping plane, and a second set of mounted contact fingers longitudinally on the clamp body, on the other side of the pinch plane, next to the first series. Each contact finger has a front face facing the plane of pinching, a dorsal side opposite to the front side, a first and second frontal ends opposite the pinch plane. The said first and second series define a first jaw between the first frontal ends of the facing contact fingers, and a second jaw between the second frontal ends opposite contact fingers. The first ends of each series are linked together by a longitudinal axis, the distance between each end of the same series being held 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 clamp body by association with radial clearance for allow movement of the second ends relative to the body of pliers. 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 opposite fingers. A such pliers are part of a pliers 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 comes to grip, by pivoting around an axis perpendicular to the pinch plane, on a bar conductive to ensure the passage of a 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 offer a clamp comprising a limited number of parts, 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 independently 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 clamp body on the support so that the bar can penetrate the first jaw even if it is not exactly in the pinch plane initial.

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 tip with a rounded leading edge 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 pliers connection comprising a clamp body defining a plane longitudinal pinching, a first series of fingers contact mounted longitudinally on the clamp body, of a side of the pinch plane, and a second set of finger contact mounted longitudinally on the clamp body, the other side of the pinch plane, opposite the first series, Each contact finger having a front face in look of the pinch plane, a dorsal face opposite the front face, first and second ends front facing the pinch plane, say first and second series defining a first jaw between the first frontal ends of the contact fingers in look, and a second jaw between the second frontal ends of the facing contact fingers.

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 the second series mounted on said clamp body, is movable regardless of 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 includes a front locking element on which carries a central frontal zone of the frontal face of the finger, and a back support element on which a central dorsal area of the dorsal side 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 frontal or dorsal areas relates to respectively the blocking or support element by through 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.According to one embodiment of the invention, the clamp body includes two transverse ends of general "U" shape, coupled to each other by at least two longitudinal uprights facing each other comprising a plurality of receptacles for receiving the fingers contact, each of the cells having a bottom and two walls lateral, each contact finger comprising a passage central or equivalent adjusted to the width between the walls lateral of the receptacles, longitudinal staples support being mounted on the clamp body parallel to the transverse uprights, blocking the faces free of the fingers mounted in said cells.

Avantageusement le corps de pince est monobloc.Advantageously, the clamp body is in one piece.

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.The alveoli, located on the opposite faces of the transverse uprights, form said support elements back, and said staples, blocking the front faces contact fingers, form the locking elements frontal.

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 interposed elastic blade between the bottom of the cell and the dorsal side of the finger associated contact. The elastic blade has a general shape in "U", and the contact finger has dorsal ends hollowed out, housing the free ends of the elastic blade U-shaped, the central branch of the elastic blade being in contact with the bottom of the cell.

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 includes a longitudinal clip per upright longitudinal, having a longitudinal central part blocking contact fingers, and two end parts clicks 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 position ready to be associated, the clamp comprises a pretensioner, 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 clamping device for connection comprising a conductive support, and a clamp connection having a clamp body defining a plane longitudinal pinching, a first series of fingers contact mounted longitudinally on the pliers body, side of the pinch plane, and a second set of finger contact mounted longitudinally on the clamp body, the other side of the pinch plane, opposite the first series, Each contact finger having a front face in look of the pinch plane, a dorsal face opposite the front face, first and second ends front facing the pinch plane, say first and second series defining a first jaw between the first frontal ends of the contact fingers in look, and a second jaw between the second frontal ends of the facing contact fingers, said clamp body being secured to the support, one of the jaws enclosing the support. According to the invention, the device includes means for associating the body of clamp on the support so that the clamp body is free tilt around a longitudinal tilt axis by 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 ends transverse "U" shaped cover the ends transverse of the support, a longitudinal tilting axis passing through said transverse branches and 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;
