Abstract
Description
La présente invention concerne un procédé pour raccorder I'extrémité dénudée d'un câble à un contact métallique maintenu dans un boitier formant l'une des deux parties d'un connecteur. The present invention relates to a method for connecting the stripped end of a cable to a metal contact held in a case forming one of the two parts of a connector.
L'invention concerne, plus particulièrement, le raccordement simultané de câbles conducteurs disposes en nappe. The invention relates, more particularly, to the simultaneous connection of conductive cables arranged in a sheet.
L'expérience a montre qu'il était toujours très difficile d'automatiser I'opération consistant à raccorder une pluralité de câbles conducteurs à des contacts maintenus dans un boîtier isolant et qu'il était également difficile d'assurer une bonne étanchéité au droit du point de pénétration du câble isolé dans le boîtier. Experience has shown that it was always very difficult to automate the operation of connecting a plurality of conductive cables to contacts maintained in an insulating housing and that it was also difficult to ensure a good seal at the level of the insulated cable penetration point in the housing.
Le procédé de l'invention a pour but de remédier à ces inconvénients et il consiste
a) à engager partiellement les contacts métalliques dans le boîtier, une partie desdits contacts s'étendant au-delà de la face correspondante dudit boîtier;
b) à raccorder les extrémités dénudées des câbles conducteurs de la nappe aux extrémités correspondantes desdits contacts
c) à repousser l'ensemble pour faire pénétrer complètement les contacts ainsi qu'une certaine portion de la nappe de câbles dans le boîtier;
d) à assurer l'étanchéité entre le boîtier et la matière isolante constituant la nappe renfermant les conducteurs.The aim of the process of the invention is to remedy these drawbacks and it consists
a) partially engaging the metal contacts in the housing, a part of said contacts extending beyond the corresponding face of said housing;
b) connecting the stripped ends of the conducting cables of the sheet to the corresponding ends of said contacts
c) pushing back the assembly in order to completely penetrate the contacts as well as a certain portion of the cable ply in the housing;
d) ensuring sealing between the housing and the insulating material constituting the sheet containing the conductors.
Le procédé de l'invention ainsi que les moyens permettant sa mise en oeuvre seront mieux compris par la description qui va suivre faite en se référant aux dessins annexés à titre d'exemple indicatif seulement, sur lesquels

FIG. 6 is a sectional view taken along line VI-VI of FIG. 5.
En se reportant à la figure 1, on voit que le problème à résoudre consiste à raccorder les extrémités dénudées 1 de câbles conducteurs, normalement noyés dans une matière isolante se présentant sous la forme d'une nappe 2, à des contacts électriques 3 maintenus dans un boîtier isolant 4 formant l'une des deux parties d'un connecteur. Referring to FIG. 1, it can be seen that the problem to be solved consists in connecting the stripped ends 1 of conductive cables, normally embedded in an insulating material in the form of a sheet 2, to electrical contacts 3 maintained in an insulating housing 4 forming one of the two parts of a connector.
La première phase du procédé consiste à placer les contacts 3 dans le boîtier 4 de façon à ce que leurs extrémités postérieures 3a s'étendent au-delà de la face 5 du boitier 4 ( figure 1). The first phase of the process consists in placing the contacts 3 in the housing 4 so that their rear ends 3a extend beyond the face 5 of the housing 4 (FIG. 1).
La seconde phase du procédé consiste à relier les extrémités 1 des câbles aux contacts 3. Cette opération peut être effectuée par un procédé de raccordement, tel que la soudure électrique par ultrasons ou courants haute fréquence, par sertissage,etc. The second phase of the process consists in connecting the ends 1 of the cables to the contacts 3. This operation can be carried out by a connection process, such as electric welding by ultrasound or high frequency currents, by crimping, etc.
puisque lesdits contacts s'étendent hors du boîtier
La troisième phase du procédé consiste à repousser dans le boîtier 4 les contacts 3 reliés aux câbles 1 de la nappe 2, l'extrémité 2a de ladite nappe pénétrant dans ledit boîtier (figure 4).since said contacts extend out of the housing
The third phase of the process consists in pushing back into the housing 4 the contacts 3 connected to the cables 1 of the ply 2, the end 2a of said ply penetrating into said housing (FIG. 4).
Pour rendre la mise en oeuvre de cette dernière phase plus facile, le boîtier 4 présente une échancrure 6 s'étendant de sa face 5 à celle 7 adjacente. De cette façon, rien ne vient freiner la pénétration de l'extrémité de la nappe 2 dans le boîtier. To make the implementation of this last phase easier, the housing 4 has a notch 6 extending from its face 5 to that 7 adjacent. In this way, nothing comes to brake the penetration of the end of the ply 2 into the housing.
La quatrième phase du procédé consiste à obturer l'échancrure 6 à l'aide d'un couvercle 8 isolant maintenu en place par tous moyens appropriés : collage, soudage par ultrasons, etc.(figures 5 et 6). The fourth phase of the process consists in closing the notch 6 using an insulating cover 8 held in place by any suitable means: bonding, ultrasonic welding, etc. (FIGS. 5 and 6).
L'invention concerne aussi d'autres moyens pour faciliter la mise en oeuvre de ce procédé. Ainsi, chaque contact 3, qui se présente sous la forme d'une barrette plate, comporte sur l'un de ses chants un ergot 9 de faible importance, susceptible, lorsqu'on introduit le contact par la face 5, de pénétrer élastiquement dans une petite échancrure 1O du boîtier.Cette disposition permet de positionner les contacts dans le boîtier et de les maintenir en place à la fin de la première phase. The invention also relates to other means to facilitate the implementation of this method. Thus, each contact 3, which is in the form of a flat bar, has on one of its edges a lug 9 of small importance, capable, when the contact is introduced via the face 5, of penetrating elastically into a small 1O notch on the housing. This arrangement allows the contacts to be positioned in the housing and to be held in place at the end of the first phase.
L'une des faces de chaque contact 3 présente une patte relevée 11 susceptible de venir prendre appui contre le fond 6a de l'échancrure 6 ( figure 5) pour limiter la pénétration dudit contact à la fin de la troisième phase. One of the faces of each contact 3 has a raised tab 11 capable of coming to bear against the bottom 6a of the notch 6 (FIG. 5) to limit the penetration of said contact at the end of the third phase.
Durant l'exécution de la troisième phase et sous l'action de la poussée qui s'exerce selon la flèche F, les ergots 9 sortent de leur échancrure 10 et se placent devant des épaulements 12 du boîtier ( figure 4) s'opposant ainsi au retrait des contacts. During the execution of the third phase and under the action of the thrust which is exerted according to arrow F, the lugs 9 come out of their notch 10 and are placed in front of shoulders 12 of the housing (FIG. 4) thus opposing when the contacts are removed.
I1 faut noter aussi que le couvercle 8 présente sur sa face interne et à son extrémité des berceaux 13 épousant le profil externe de la nappe 2 et coopérant avec au moins un berceau 14 du boîtier pour enserrer ladite nappe ( figures 5 et 6). I1 should also be noted that the cover 8 has on its internal face and at its end cradles 13 matching the external profile of the ply 2 and cooperating with at least one cradle 14 of the housing to grip said ply (Figures 5 and 6).
Le couvercle 8 présente intérieurement un bourrelet périphérique 15 ( figure 6) s'engageant dans une rainure 16 (figure 2) du boîtier. De cette façon, le couvercle est parfaitement positionné préalablement à sa solidarisation au boîtier et à la nappe 2. The cover 8 has internally a peripheral bead 15 (Figure 6) engaging in a groove 16 (Figure 2) of the housing. In this way, the cover is perfectly positioned before it is fixed to the housing and to the ply 2.
Le couvercle 8 présente, aussi, intérieurement une butéepeigne 17 s'opposant au recul des contacts 3 si la nappe 2 est soumise à un effort détraction intempestif. The cover 8 also has, internally, a comb stop 17 opposing the recoil of the contacts 3 if the sheet 2 is subjected to an untimely detraction force.
