Abstract

The subject of the present invention is a process for manufacturing connector contacts. According to this process, transverse profiled borders 2 are formed in a metal strip 1, which borders are extended along one of their longitudinal edges by a series of portions 4 which are intended to constitute the connection parts of the contacts and which are themselves extended via tongues or strips 5 by portions 6 which are intended to constitute the parts for connecting the said contacts to the cables and which are joined to the next profiled border 2, the tongues 6 having an angle of inclination which increases and decreases from the centre of the profiled borders out to their extremities; next, the said portions are folded or bent so as to form the connection parts and the parts for connecting the contacts, and a profiled border 2 and the contacts which are attached to it are separated from the band.

Description

Les connecteurs destinés à être raccordés à des nappes de câbles électriques comportent des contacts dont les parties de connexion sont écartées à un premier pas alors que leurs parties de raccordement aux câbles d'une nappe sont écartées à un deuxième pas différent du premier et en général plus faible que lui. The connectors intended to be connected to plies of electric cables comprise contacts, the connection parts of which are separated at a first step whereas their connection parts to the cables of a ply are separated at a second pitch different from the first and in general weaker than him.

Ces contacts sont jusqu'à présent fabriqués individuellement; ils sont également mis en place individuellement dans le boîtier du connecteur, chaque contact subissant un désaxement d'autant plus important qu'il est plus éloigné du centre du connecteur, de façon à rattraper l'écart entre les pas. L'opération de montage est de ce fait très délicate.These contacts have so far been produced individually; they are also placed individually in the connector housing, each contact undergoing an offset that is all the more important as it is further from the center of the connector, so as to make up for the difference between the steps. The assembly operation is therefore very delicate.

La présente invention a pour objet un procédé de fabrication de contacts, dans lequel un ensemble de contacts est fabriqué simultanément et peut ensuite être mis en place d'un bloc dans le boîtier d'un connecteur. The subject of the present invention is a method of manufacturing contacts, in which a set of contacts is produced simultaneously and can then be put in place in a block in the housing of a connector.

Le procédé selon l'invention est caractérisé en ce qu'on forme dans une bande métallique des bandelettes transversales prolongées sur l'un de leurs bords longitudinaux par une série de portions destinées à constituer les parties de connexion des contacts et elles-mêmes prolongées par l'intermédiaire de languettes ou lamelles, par des portions destinées à constituer les parties de raccordement aux câbles desdits contacts et attenantes à la bandelette suivante, les languettes présentant une inclinaison allant en croissant ou en décroissant depuis le centre des bandelettes jusqu'à leurs extrémités, en ce qu'on plie ou cintre ensuite lesdites portions de façon à mettre en forme les parties de connexion et les parties de raccordement des contacts, et en ce qu'on sépare de la bande une bandelette et les contacts qui lui sont attenants. The method according to the invention is characterized in that transverse strips extended on one of their longitudinal edges are formed in a metal strip by a series of portions intended to constitute the connection parts of the contacts and themselves extended by by means of tongues or strips, by portions intended to constitute the parts for connection to the cables of said contacts and adjoining the next strip, the tongues having an inclination increasing or decreasing from the center of the strips to their ends , in that the said portions are then folded or bent so as to shape the connection parts and the connection parts of the contacts, and in that a strip is separated from the strip and the contacts adjoining it.

L'ensemble de contacts formé dans lequel les parties de raccordement sont plus écartées les unes des autres que les parties de connexion, ou plus rapprochées selon le cas, est facilement mis en place dans le boîtier d'un connecteur. I1 suffit ensuite de séparer les contacts par découpe de la bandelette. The set of contacts formed in which the connection parts are further apart from each other than the connection parts, or closer together as the case may be, is easily placed in the housing of a connector. I1 then suffices to separate the contacts by cutting the strip.

L'axe longitudinal des contacts est disposé dans le sens longitudinal de la bande, de sorte qu'un seul outillage suffit pour réaliser des ensembles de contacts comportant des nombres différents de contacts. L'outillage correspond au nombre maximal de contacts; si l'on désire des ensembles de contacts en nombre plus faible, il suffit de retirer à chaque extrémité le même nombre de poinçons et de matrices. The longitudinal axis of the contacts is arranged in the longitudinal direction of the strip, so that a single tool is sufficient to produce sets of contacts comprising different numbers of contacts. The tools correspond to the maximum number of contacts; if smaller numbers of contact assemblies are desired, simply remove the same number of punches and dies at each end.

On a décrit ci-après, à titre d'exemple non limitatif, un mode de mise en oeuvre du procédé selon l'invention, avec référence au dessin annexé dans lequel :
La Figure 1 montre en plan une bande dans laquelle sont formées une série de bandelettes;
La Figure 2 est une vue semblable à la Figure 1 après mise en forme;
La Figure 3 en est une coupe suivant III-III de la Figure 2.
An embodiment of the method according to the invention has been described below, by way of nonlimiting example, with reference to the appended drawing in which:
Figure 1 shows in plan a strip in which are formed a series of strips;
Figure 2 is a view similar to Figure 1 after shaping;
Figure 3 is a section along III-III of Figure 2.

La Figure 4 en est une vue en plan. Figure 4 is a plan view.

Selon l'invention, pour obtenir une bande de contacts déportés, on part d'une bande plane qui est désignée à la Figure 1 d'une façon générale par la référence 1. Dans cette bande sont formées par découpe des bandelettes transversales de liaison 2 qui sont reliées entre elles par des bandelettes longitudinales d'entraînement 3. Chaque bandelette 2 est solidaire d'une série de portions longitudinales 4 qui sont sensiblement rectangulaires légèrement espacées les unes des autres, ou simplement cisaillées, et destinées à former les fiches de connexion, comme représenté, ou les douilles de connexion. Chacune de ces portions 4 est re-i liée par une languette 5 à une portion longitudinale 6 destinée à former la partie de raccordement du contact à un câble et soli-; daire de la bandelette 2 suivante.Les portions 4 et 6 sont reliées aux bandelettes 2 par des portions de faible largeur 7 et 8 propres à permettre une séparation facile des contacts. According to the invention, to obtain a strip of offset contacts, one starts from a flat strip which is generally designated in FIG. 1 by the reference 1. In this strip are formed by cutting transverse connecting strips 2 which are interconnected by longitudinal drive strips 3. Each strip 2 is secured to a series of longitudinal portions 4 which are substantially rectangular slightly spaced from each other, or simply sheared, and intended to form the connection plugs , as shown, or the connection sockets. Each of these portions 4 is re-i linked by a tongue 5 to a longitudinal portion 6 intended to form the connection part of the contact to a cable and solid; Daire of the following strip 2. The portions 4 and 6 are connected to the strips 2 by small width portions 7 and 8 adapted to allow easy separation of the contacts.

Les portions 4 sont en nombre égal à celui des portions 6 mais leur écart est plus grand que celui desdites portions. Lorsque la bande 1 est destinée à la formation d'une bande de contacts comportant un nombre impair de contacts, comme à la Figure 1, la languette centrale 5a est orientée longitudinalement mais les languettes disposées de part et d'autre de cette languette centrale présente une inclinaison qui est d'autant plus grande que la languette est plus éloignée de la languette centrale 5a. En revanche, lorsque la bande 1 est destinée à la formation d'une bande de contacts comportant un nombre pair de contacts, toutes les lamelles 5 sont inclinées, les unes dans un sens par rapport à l'axe de la bande et les autres dans le sens opposé par rapport à cet axe.  The portions 4 are equal in number to that of the portions 6 but their difference is greater than that of said portions. When the strip 1 is intended for the formation of a contact strip comprising an odd number of contacts, as in FIG. 1, the central tab 5a is oriented longitudinally but the tabs arranged on either side of this central tab have an inclination which is all the greater as the tongue is farther from the central tongue 5a. On the other hand, when the strip 1 is intended for the formation of a contact strip comprising an even number of contacts, all the strips 5 are inclined, some in a direction relative to the axis of the strip and the others in the opposite direction with respect to this axis.

Les portions 4 sont ensuite pliées autour de leur axe pour former les parties de connexion 9, mâles ou femelles des contacts; de même, les portions 6 sont pliées pour former leurs parties de raccordement 10 aux câbles (Figures 2 à 4). The portions 4 are then folded around their axis to form the connection parts 9, male or female of the contacts; similarly, the portions 6 are folded to form their connection parts 10 to the cables (Figures 2 to 4).

Après séparation des bandelettes 2 de la bande et rupture des portions 7, on obtient ainsi un ensemble de contacts dans lequel l'écartement des portions 9 est supérieur à celui des portions 10 et dans lequel les axes de ces portions 9 et les axes de ces portions 10 sont situés dans deux plans écartés l'un de l'autre. After separation of the strips 2 from the strip and rupture of the portions 7, a set of contacts is thus obtained in which the spacing of the portions 9 is greater than that of the portions 10 and in which the axes of these portions 9 and the axes of these portions 10 are located in two planes spaced from one another.

L'ensemble est ensuite mis en place dans le boîtier d'un connecteur, ce qui se fait facilement. Il ne reste plus qu'à séparer les différents contacts les uns des autres par rupture des portions 8. The assembly is then placed in the housing of a connector, which is easy to do. It only remains to separate the different contacts from each other by breaking the portions 8.

Il va de soi que la présente invention ne doit pas être considérée comme limitée au mode de mise en oeuvre décrit et représenté, mais en couvre, au contraire, toutes les variantes.  It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
