Description

La présente invention porte sur les contacts autodénudants de raccordement de conducteurs électriques isolés, sans dénudage préalable de ces conducteurs.The present invention relates to insulation displacement contacts for connection of insulated electrical conductors, without prior stripping of these conductors.

Ces contacts sont en tant que tels déjà connus. Ils sont du type à fourche autodénudante.These contacts are as such already known. They are of the type with insulation displacement fork.

Un tel contact autodénudant est décrit notamment dans le document FR-A 2457 573. Il est à fourche autodénudante simple ou double et dans ce dernier cas de combinaisons variées possibles telles que tête bêche ou côte à côte.Such an insulation displacement contact is described in particular in document FR-A 2457 573. It has a simple or double insulation displacement fork and in the latter case of various possible combinations such as head to tail or side by side.

Le contact à fourche autodénudante simple est formé par une pièce conductrice dans laquelle une fente définit les deux branches élastiques de la fourche. Il est en outre à entrée de conducteur isolé dans la fente, couplée à une extrémité de ladite fente par au moins un étage de sectionnement d'isolant et éventuellement ouverte sur l'un des bords de la pièce, et à trou d'élasticité des deux branches situé à l'autre extrémité de ladite fente, sur son fond. Le contact à fourche double côte à côte peut avoir l'une des branches de ses fourches qui leur est commune.The simple insulation displacement fork contact is formed by a conductive part in which a slot defines the two elastic branches of the fork. It is furthermore with an insulated conductor entry into the slot, coupled to one end of said slot by at least one insulating sectioning stage and possibly open on one of the edges of the part, and with elasticity hole of the two branches located at the other end of said slot, on its bottom. The double fork contact side by side can have one of the branches of its forks which is common to them.

Selon ce document, l'écartement des deux branches de chaque fourche est obtenu soit par un écrasement local et le déplacement résultant de matière sur l'une des deux branches, soit par deux écrasements et les déplacements résultants de matière sur l'une et l'autre des deux branches. Cet écrasement ou les deux écrasements sont effectués près du ou des deux bords de la fente, entre son fond et l'étage de sectionnement d'isolant, par un poinçon de section circulaire. Ils donnent lieu à un bossage arrondi sur le bord de la seule branche concernée ou des deux branches, calibrant l'écartement des deux branches, notamment.According to this document, the spacing of the two branches of each fork is obtained either by local crushing and the resulting displacement of material on one of the two branches, or by two crushing and the resulting displacements of material on one and the other of the two branches. This crushing or the two crushings are carried out near the or two edges of the slot, between its bottom and the insulating sectioning stage, by a punch of circular section. They give rise to a rounded boss on the edge of the single branch concerned or of the two branches, calibrating the spacing of the two branches, in particular.

Dans le premier cas, l'écartement des deux branches n'est pas symétrique par rapport à l'axe de fourche. Cette disposition est gênante lorsque le fil conducteur à raccorder est amené dans l'axe de la fourche par un moyen de mise en place et de raccordement, tel qu'un poussoir notamment. Elle conduit à un effort d'insertion se trouvant augmenté.In the first case, the spacing of the two branches is not symmetrical with respect to the fork axis. This arrangement is troublesome when the conductive wire to be connected is brought into the axis of the fork by means of positioning and connection, such as a pusher in particular. It leads to an increased integration effort.

Dans le deuxième cas, l'écartement des deux branches est théoriquement symétrique. Il ne l'est cependant pas parfaitement ou suffisamment, en pratique.In the second case, the spacing of the two branches is theoretically symmetrical. However, it is not perfectly or sufficiently in practice.

Dans les deux cas le poinçon utilisé est de faible dimension et est donc fragile.In both cases the punch used is small and is therefore fragile.

Le document US-A-4 333 700 décrit également un contact autodénudant à deux bras élastiques, définis sur une lame conductrice, séparés par une fente et solidaires l'un de l'autre sur une partie de base de la lame. La fente est à bords non jointifs et se prolonge à l'opposé de la partie de base par une entrée de conducteur isolé et un étage de sectionnement d'isolant et de couplage de l'entrée à la fente. Les portions terminales des bras au-delà de la fente et les portions en vis-à-vis sur la longueur de la fente sont façonnées pour présenter une épaisseur réduite et mieux pénétrer à travers l'isolant du conducteur.Document US-A-4 333 700 also describes a self-stripping contact with two elastic arms, defined on a conductive strip, separated by a slot and integral with one another on a base part of the strip. The slot has non-contiguous edges and extends opposite the base part by an insulated conductor inlet and an insulating sectioning stage and coupling of the inlet to the slot. The end portions of the arms beyond the slot and the facing portions along the length of the slot are shaped to have a reduced thickness and better penetrate through the insulation of the conductor.

La réalisation d'un tel contact est relativement longue et délicate pour un contrôle rigoureux de l'ouverture de l'entrée de conducteur isolé, de l'étage de sectionnement d'isolant et de la fente sur leur longueur, ainsi que pour un contrôle aisé de l'épaisseur rendue réduite des portions concernées.The realization of such a contact is relatively long and delicate for a rigorous control of the opening of the entry of the insulated conductor, of the insulating isolation stage and of the slot along their length, as well as for a control easy of the reduced thickness of the portions concerned.

Le document FR-A-2 155 613 décrit un contact de même type, mais d'une part comportant trois bras et deux fentes entre eux, avec une entrée de conducteur isolé et un étage de sectionnement d'isolant prolongeant chaque fente, et d'autre part comportant un embouti sur les portions des bras situées le long de la seule partie terminale de chaque fente, du côté de la partie de base de solidarisation des bras. Chaque fente a ainsi son ouverture allant en s'élargissant depuis les emboutis jusqu'à l'extrémité opposée. L'étage de sectionnement est de même épaisseur que celle les bras, exception faite des portions embouties, ce qui peut poser un problème pour le sectionnement de l'isolant du conducteur.Document FR-A-2 155 613 describes a contact of the same type, but on the one hand comprising three arms and two slots between them, with an insulated conductor entry and an insulating sectioning stage extending each slot, and d 'other hand comprising a stamped on the portions of the arms located along the single end portion of each slot, on the side of the base portion for securing the arms. Each slot thus has its opening widening from the stamped to the opposite end. The sectioning stage is the same thickness as that of the arms, with the exception of the stamped portions, which can pose a problem for the sectioning of the conductor insulation.

La présente invention a pour but notamment d'éviter les inconvénients des contacts autodénudants connus décrits ci-avant.The object of the present invention is in particular to avoid the drawbacks of the known insulation displacement contacts described above.

Elle a pour objet un contact autodénudant constitué par une lame conductrice comportant au moins une fente, deux branches élastiques définies sur ladite lame, de part et d'autre de chaque fente, et une entrée de conducteur isolé couplée à une première extrémité de ladite fente, par un étage de sectionnement d'isolant, et présentant des portions d'épaisseur réduite prévues sur lesdites branches le long d'au moins une partie de ladite fente, caractérisé en ce que lesdites portions d'épaisseur réduite constituent un poinçonnage unique de refoulement de matière, sensiblement rectangulaire et réalisé simultanément sur les seules parties desdites deux branches élastiques situées de part et d'autre sensiblement de ladite première extrémité de ladite fente, mais prévu non attenant à ladite entrée de conducteur isolé, et en ce que lesdites branches de part et d'autre de chaque fente sont à bords rectilignes en vis-à-vis et en contact en pression sur l'axe de ladite fente, uniquement le long sensiblement de la dimension correspondante de ladite largeur dudit poinçonnage.It relates to a insulation displacement contact constituted by a conductive strip comprising at least one slot, two elastic branches defined on said blade, on either side of each slot, and an insulated conductor input coupled to a first end of said slot, by an insulating sectioning stage, and having reduced thickness portions provided on said branches along at least part of said slot, characterized in that said portions of reduced thickness constitute a single punching for delivery of material, substantially rectangular and produced simultaneously on the only parts of said two elastic branches situated on either side other substantially from said first end of said slot, but provided not adjoining said insulated conductor inlet, and in that said branches on either side of each slot are with straight edges facing and in contact in pressure on the axis of said slot, only along substantially the corresponding dimension of said width of said punching.

En outre, l'entrée de conducteur isolé, réalisée initialement par une découpe sensiblement en V, a son fond ouvert par ledit poinçonnage pour former ledit étage de sectionnement et définir un court passage axial allant en se rétrécissant depuis le fond dudit V d'entrée jusqu'au dit poinçonnage.In addition, the insulated conductor input, initially produced by a substantially V-shaped cutout, has its bottom open by said punching to form said sectioning stage and define a short axial passage which tapers from the bottom of said input V until said punching.

Les caractéristiques et avantages de la présente invention ressortiront de la description faite ci-après d'un exemple de réalisation et d'un outil d'exécution illustrés dans les dessins ci-annexés. Dans ces dessins :

  • la figure 1 montre un contact autodénudant à fourche simple, selon l'invention,
  • la figure 2 est une vue en coupe selon la ligne II-II de la figure 1,
  • la figure 3 est une vue en perspective d'un poinçon utilisé selon l'invention.
The characteristics and advantages of the present invention will emerge from the description given below of an exemplary embodiment and of an execution tool illustrated in the accompanying drawings. In these drawings:
  • FIG. 1 shows a insulation displacement contact with a simple fork, according to the invention,
  • FIG. 2 is a sectional view along the line II-II of FIG. 1,
  • Figure 3 is a perspective view of a punch used according to the invention.

Le contact autodénudant est réalisé dans une lame conductrice 1, présentant une fente 2. Cette fente 2 définit de part et d'autre d'elle sur la lame les deux branches élastiques 3 et 4 de la fourche autodénudante. Elle débouche à l'une de ses extrémités dans une entrée 5 de conducteur isolé à raccorder sans dénudage préalable dans la fente, cette entrée 5 étant dans l'exemple illustré dans la figure 1 ouverte sur l'un des petits bords de la lame. Elle débouche à son autre extrémité dans un trou 6 d'élasticité des branches 3 et 4, ce trou 6 étant de forme ovale et non ouvert sur l'un quelconque des bords de la lame. L'entrée 5 et le trou d'élasticité 6 ont leur axe aligné sur celui de la fente 2.The insulation displacement contact is produced in a conductive strip 1, having a slot 2. This slot 2 defines on either side of it on the strip the two elastic branches 3 and 4 of the insulation displacement fork. It opens at one of its ends into an inlet 5 of insulated conductor to be connected without prior stripping in the slot, this inlet 5 being in the example illustrated in FIG. 1 open on one of the small edges of the blade. It opens at its other end into a hole 6 of elasticity of the branches 3 and 4, this hole 6 being of oval shape and not open on any of the edges of the blade. The inlet 5 and the elasticity hole 6 have their axis aligned with that of the slot 2.

L'entrée 5 est obtenue en réalisant une découpe, en forme de V à base pouvant être tronquée ou non, dans le bout de la lame, avec l'ouverture de ce V formant un léger étranglement de rétention de conducteur isolé dans cette entrée. La fente 2 est par contre réalisée sans enlèvement de matière, avec ses bords initialement jointifs avant sa légère ouverture résultant de l'écartement des deux branches réalisé selon l'invention.The entry 5 is obtained by making a cut, in the form of a V with a base which can be truncated or not, in the end of the blade, with the opening of this V forming a slight constriction of retention of insulated conductor in this entry. The slot 2 is on the other hand made without removing material, with its edges initially contiguous before its slight opening resulting from the separation of the two branches produced according to the invention.

Ce contact comporte un poinçonnage unique de refoulement de matière, formant une empreinte rectangulaire 7 s'étendant en continu sur ses deux branches 3 et 4. Ce poinçonnage est réalisé simultanément sur les deux branches, mais uniquement sur leurs parties situées au niveau de la partie terminale de fente qui est proche de l'entrée 5. Ce poinçonnage 7 est situé sensiblement à l'extrémité de la fente, mais n'est cependant pas tout à fait attenant à la base tronquée du V de l'entrée 5.This contact comprises a single punching of material discharge, forming a rectangular imprint 7 extending continuously on its two branches 3 and 4. This punching is carried out simultaneously on the two branches, but only on their parts located at the level of the part slot terminal which is close to the entry 5. This punching 7 is situated substantially at the end of the slot, but is however not entirely adjacent to the truncated base of the V of the entry 5.

Avantageusement, ce poinçonnage unique rectangulaire 7 n'est réalisé que sur l'une des faces de la lame, ainsi que montré dans la figure 2. Il peut bien entendu, bien que non nécessaire, être réalisé sur les deux faces de la lame.Advantageously, this single rectangular punching 7 is only carried out on one of the faces of the blade, as shown in FIG. 2. It can of course, although not necessary, be carried out on both sides of the blade.

Ce poinçonnage 7 permet d'obtenir par écrasement et déplacement de matière, un bossage aplati 7A ou 7B sur chacune des deux branches, assurant l'écartement des deux branches de part et d'autre du poinçonnage et leur mise en contact en pression sur la largeur du poinçonnage. Il permet aussi d'obtenir une épaisseur réduite de la lame à son niveau et en particulier des bords en contact en pression des bossages, qui participent donc à une bonne pénétration des bords de la fente à travers l'épaisseur totale de l'isolant du conducteur.This punching 7 makes it possible to obtain, by crushing and displacement of material, a flattened boss 7A or 7B on each of the two branches, ensuring the spacing of the two branches on either side of the punching and their contacting under pressure over the width of the punching. It also makes it possible to obtain a reduced thickness of the blade at its level and in particular of the edges in contact with pressure of the bosses, which therefore participate in good penetration of the edges of the slot through the total thickness of the insulation of the driver.

Ces deux bossages 7A et 7B provoquent aussi l'ouverture en son milieu de la base tronquée du V de l'entrée 5, cette base tronquée étant simplement fendue mais non ouverte initialement. Les deux parties de la base tronquée ainsi ouverte définissent directement les deux pointes acérées 5A, 5B en regard l'une de l'autre, constituant l'étage de sectionnement d'isolant, et se prolongent jusqu'au poinçonnage 7 par un court passage 5C allant en se rétrécissant.These two bosses 7A and 7B also cause the opening in the middle of the truncated base of the V of the inlet 5, this truncated base being simply split but not initially opened. The two parts of the truncated base thus opened directly define the two sharp points 5A, 5B facing each other, constituting the insulating sectioning stage, and extend to the punching 7 by a short passage 5C tapering.

Le poinçon d'exécution du poinçonnage précité 7 est illustré à échelle sensiblement double dans la figure 3 et désigné sous la référence globale 10. Son extrémité 11 de montage dans un porte poinçon est de section sensiblement carrée. Sa partie terminale opposée d'emboutissage est de section réduite par la présence de deux chanfreins terminaux 12 sur deux de ses faces latérales opposées. L'extrémité d'emboutissage 13 est définie en bout de ces deux chanfreins 12 par une arête terminale arrondie entre eux.The punch for carrying out the aforementioned punching 7 is illustrated on a substantially double scale in FIG. 3 and designated under the general reference 10. Its end 11 for mounting in a punch holder is of substantially square section. Its opposite end stamping part is of reduced section by the presence of two end chamfers 12 on two of its opposite side faces. The stamping end 13 is defined at the end of these two chamfers 12 by a terminal edge rounded between them.
