L'invention vise des éléments de boîtier de connecteurs électriques du type comprenant un corps avec une série de canaux destinés à recevoir, chacun, un organe de contact électrique, chaque canal comportant des moyens conjugués avec un organe de contact électrique pour le verrouillage de celui-ci.The invention relates to electrical connector housing elements of the type comprising a body with a series of channels intended to each receive an electrical contact member, each channel comprising means combined with an electrical contact member for locking the latter. -this.
Dans ce type de connecteur, pour éviter tout dé- placement de l'organe de contact électrique, on prévoit des moyens supplémentaires de verrouillage dudit organe de contact électrique. Ces moyens sont généralement complexes et nécessitent, comme ces éléments de boîtier sont en matière plastique moulée, la réalisation d'un moule relative- ment cher.In this type of connector, to avoid any displacement of the electrical contact member, additional means for locking said electrical contact member are provided. These means are generally complex and require, as these housing elements are made of molded plastic, the production of a relatively expensive mold.
L'un des buts de la présente invention est de réaliser un élément de boîtier relativement simple. L'élément de boîtier, selon l'invention, est du type comprenant un module comportant une série de canaux destinés à recevoir, chacun, un organe de contact électrique comportant un corps avec, à une extrémité, des moyens de raccordement d'un conducteur électrique, tandis que l'autre extrémité est destinée à recevoir un organe de contact électrique complémentaire, ledit corps présentant un épaulement destiné à coopérer avec une première butée d'une languette élastique prévue dans ledit canal correspondant, ledit élément de boîtier étant caractérisé en ce que l'organe de contact électrique présente, en saillie, une patte élastique de retenue s 'étendant en direction des pattes de sertissage, tandis que la languette élastique présente une seconde butée destinée à coopérer avec l'extrémité libre de la patte de retenue, un étui étant prévu et agencé pour présenter un logement destiné à recevoir le module et à verrouiller celui-ci, ladite languette élastique et le logement étant disposés de manière que, lorsque le module est inséré dans ledit logement de l'étui, ladite languette élastique est bloquée.One of the aims of the present invention is to provide a relatively simple housing element. The housing element, according to the invention, is of the type comprising a module comprising a series of channels intended to each receive an electrical contact member comprising a body with, at one end, means for connecting an electrical conductor, while the other end is intended to receive a complementary electrical contact member, said body having a shoulder intended to cooperate with a first stop of an elastic tongue provided in said corresponding channel, said element housing being characterized in that the electrical contact member has, projecting, an elastic retaining lug extending in the direction of the crimping lugs, while the elastic tongue has a second stop intended to cooperate with the free end of the retaining tab, a case being provided and arranged to present a housing intended to receive the module and to lock it, said elastic tab and the housing being arranged so that, when the module is inserted in said housing of the 'holster, said elastic tongue is blocked.
Grâce à cette disposition, on réalise un élément de boîtier de connecteur dans lequel l'organe de contact est fixé par un double verrouillage et dans lequel, lorsque le module est inséré dans l'étui, la languette élastique ne peut être soulevée intempestivement.Thanks to this arrangement, a connector housing element is produced in which the contact member is fixed by a double locking mechanism and in which, when the module is inserted in the case, the elastic tongue cannot be lifted inopportune.
De préférence, l'étui comporte des moyens pour s'opposer à la mise en place du module dans le logement si l'organe de contact électrique n'est pas convenablement' inséré dans le canal.Preferably, the case comprises means to oppose the establishment of the module in the housing if the electrical contact member is not properly 'inserted into the channel.
Suivant un détail constructif, le logement de l'étui présente un décrochement contre lequel peut venir buter l'extrémité libre de la languette élastique si l'organe de contact électrique femelle n'est pas convenablement inséré dans le canal. Suivant une autre caractéristique constructive, l'étui comporte un crochet, tandis que la paroi correspondante du module est pourvue d'un ergot destiné à coopérer avec le crochet pour assurer le verrouillage du module dans le logement de 1 ' étui.According to a constructive detail, the housing of the case has a recess against which can abut the free end of the elastic tongue if the female electrical contact member is not properly inserted into the channel. According to another constructive characteristic, the case comprises a hook, while the corresponding wall of the module is provided with a lug intended to cooperate with the hook to ensure the locking of the module in the housing of the case.
Suivant une variante de réalisation, l'organe de contact électrique comporte deux pattes élastiques disposées de part et d'autre du corps, tandis que le module pré- sente une seconde languette élastique pourvue d'une butée avec laquelle vient coopérer l'extrémité libre de la seconde patte élastique.According to an alternative embodiment, the electrical contact member comprises two elastic tabs arranged on either side of the body, while the module has a second elastic tongue provided with a stop with which the free end cooperates. of the second elastic tab.
Suivant un détail constructif, la languette élas- tique, au voisinage de son extrémité libre, comporte un bossage destiné à porter contre l'extrémité correspondante de l'organe de contact électrique.According to a constructive detail, the elastic tongue, in the vicinity of its free end, includes a boss intended to bear against the corresponding end of the electrical contact member.
Suivant une autre caractéristique, chaque lan- guette élastique comporte, à son extrémité libre, un bossage, les bossages se faisant vis-à-vis et étant destinés à enserrer l'organe de contact électrique.According to another characteristic, each elastic tongue has, at its free end, a boss, the bosses facing each other and being intended to enclose the electrical contact member.
L'invention se rapporte également à un outil qui permet de faciliter l'extraction d'un organe de contact électrique de son canal, ledit outil étant caractérisé en ce qu'il est constitué d'un élément en U avec une âme et deux ailes destinées à coopérer avec l'organe contact électrique de manière à soulever les languettes élastiques pour dégager les pattes élastiques correspondantes et replier celles-ci contre le corps de l'organe de contact électrique. L'invention va maintenant être décrite avec plus de détails en se référant à des modes de réalisation particulier donnés à titre d'exemple seulement et représentés aux dessins annexés.The invention also relates to a tool which facilitates the extraction of an electrical contact member from its channel, said tool being characterized in that it consists of a U-shaped element with a core and two wings intended to cooperate with the electrical contact member so as to lift the elastic tabs to release the corresponding elastic tabs and fold them against the body of the electrical contact member.

Figure 13 montre en coupe l'utilisation d'un outil pour 1 ' étui de la figure 7. Figure 14 montre en coupe l'utilisation d'un outil i pour l'étui de la figure 8. ι A la figure 1, on a représenté un organe 'de contact électrique 1 qui comprend, à une extrémité, une i première paire de pattes 2 pour le sertissage d'un conducteur électrique 3 logé dans sa gaine isolante et une seconde paire de pattes 4 pour le sertissage du conducteur dénudé. !Figure 13 shows in section the use of a tool for the case of Figure 7. Figure 14 shows in section the use of a tool i for the case of Figure 8. ι In Figure 1, there is shown a body 'of electrical contact 1 which comprises, at one end, a first pair of i lugs 2 for crimping an electrical conductor 3 housed in its insulating sheath and a second pair of lugs 4 for crimping the stripped conductor. !
I L'organe de contact électrique 1 est prolongé par un corps 5 raccordé par un épaulement 6 et dans lequel s'étendent des lames élastiques 7 destinées à enserrer j un organe de contact mâle complémentaire. '<I The electrical contact member 1 is extended by a body 5 connected by a shoulder 6 and in which extend elastic blades 7 intended to grip a complementary male contact member. ' <
Le corps 5 est découpé pour présenter une patte J de retenue élastique 8 dont l'extrémité libre est tournée vers les pattes de sertissage 2 et 4. L'organe de contact électrique 1 est destiné à être engagé par une ouverture d'introduction 9 dans un canal 10 d'un module 11. i ! Le module 11 est constitué d'un corps en matière plastique de forme générale parallelepipedique avec deux parois latérales lia et 11b. Dans la paroi 11b est découpée i une languette élastique 12 comportant un bec 17 raccordé à une première butée 13 destinée à coopérer avec l' épaulement 6 et une seconde butée 14 contre laquelle vient porter l'extrémité de la patte élastique 8, ladite languette él'as- tique 12 étant terminée par une extrémité 15 présentant une partie arrondie 16 avec un bossage 16a destiné à porter contre une extrémité 8a de la patte élastique 8 (voir figures 2 et 3) afin d'assurer un bon positionnement de l'organe de contact 1 dans le module 11.The body 5 is cut to present an elastic retaining tab J 8 whose free end faces the crimping tabs 2 and 4. The electrical contact member 1 is intended to be engaged by an introduction opening 9 in a channel 10 of a module 11. i! The module 11 consists of a plastic body of generally parallelepiped shape with two side walls 11a and 11b. In the wall 11b is cut i an elastic tongue 12 comprising a spout 17 connected to a first stop 13 intended to cooperate with the shoulder 6 and a second stop 14 against which the end of the elastic tab 8 comes to bear, said elastic tongue 'the attic 12 being terminated by an end 15 having a rounded portion 16 with a boss 16a intended to bear against one end 8a of the elastic tab 8 (see Figures 2 and 3) in order to ensure correct positioning of the contact member 1 in the module 11.
Le module 11 est destiné à être disposé dans un logement 19 d'un étui 20 (voir figure 4) .The module 11 is intended to be placed in a housing 19 of a case 20 (see FIG. 4).
L'étui 20 comporte, à une extrémité, une ouverture 21 pour l'engagement du module 11, l'extrémité opposée étant fermée par une paroi 22 présentant une fente 23 pour l'engagement d'un organe de contact mâle disposé dans un élément de boîtier complémentaire et destiné à s ' insérer dans l'organe de contact femelle 1 (voir figure 4).The case 20 comprises, at one end, an opening 21 for engaging the module 11, the opposite end being closed by a wall 22 having a slot 23 for engaging a male contact member disposed in an element of complementary housing and intended to be inserted in the female contact member 1 (see FIG. 4).
L'étui 20 présente dans son logement 19 un décro- chement 26 de manière, si l'organe 1 n'est pas convenablement engagé dans le canal 10, à s'opposer à la mise en place du module (voir figures 5 et 6) .The case 20 has in its housing 19 a recess 26 so as, if the member 1 is not properly engaged in the channel 10, to oppose the establishment of the module (see Figures 5 and 6 ).
En effet, si l'organe 1 n'est pas suffisamment en- gagé dans le canal 10, le bec 17 de la butée 13 porte contre le corps 5 et la languette élastique 12 reste soulevée de sorte qu'elle bute contre le décrochement 26 (voir figure 6) . Le module 11, sur sa paroi lia, au voisinage de l'ouverture d'introduction 9, comporte un ergot 27 présentant une rampe 27a à une extrémité et un abrupt 27b à l'autre extrémité, tandis que l'étui présente un creusage 28 pour former une partie élastique 29 terminée par un crochet 30 présentant une rampe 30a.In fact, if the member 1 is not sufficiently engaged in the channel 10, the spout 17 of the stop 13 bears against the body 5 and the elastic tongue 12 remains raised so that it abuts against the setback 26 (see figure 6). The module 11, on its wall 11a, in the vicinity of the introduction opening 9, comprises a lug 27 having a ramp 27a at one end and a steep 27b at the other end, while the case has a hollow 28 to form an elastic part 29 terminated by a hook 30 having a ramp 30a.
Lorsqu'on met en place le module 11 dans l'étui 20, la rampe 27a coopère avec la rampe 30a de ma- nière que la partie élastique 29 fléchisse pour permettre l'engagement de l'ergot 27 dans le creusage 28, l'abrupt 27b coopérant avec le crochet 30 pour assurer le verrouillage.When the module 11 is placed in the case 20, the ramp 27a cooperates with the ramp 30a nière that the elastic part 29 flexes to allow the engagement of the lug 27 in the hollow 28, the abrupt 27b cooperating with the hook 30 to ensure locking.
On a représenté, sur les figures 1 à 6, un élément de boîtier de connecteur avec un module 11 et un étui 20 destiné à recevoir ledit module. On n'a figuré qu'une vois, mais bien entendu, le module comporte une série de voi-ss disposées côte à côte et l'étui a une longueur correspondante pour recevoir ledit module.FIGS. 1 to 6 show a connector housing element with a module 11 and a case 20 intended to receive said module. We only figured a see, but of course, the module includes a series of voi-ss arranged side by side and the case has a corresponding length to receive said module.
La figure 7 montre une variante de réalisatic-n d'un organe de contact électrique 40 qui présente deux pa;t- tes élastiques 41 et 41a. Dans ce cas, le module 42 com- ι porte deux languettes élastiques 44 et 44a terminées p'ar des bossages 45 et 45a qui se font vis-à-vis et destinés à porter contre l'extrémité 46 de l'organe de contact électrique 40, adjacentes aux pattes 41 pour parfaitement caler celui-ci dans le module 42. .FIG. 7 shows an alternative embodiment of an electrical contact member 40 which has two elastic parts 41 and 41a.

L'organe 60 est destiné à être logé dans un module 69 qui présente une première languette élastique 70 avec un bec 71, une première butée 72 et une seconde butée 73. Le module 69 comporte une seconde languette élastique 70a pourvue d'une butée 74.The member 60 has a shoulder 65 and on the flat bar 64 is engaged and fixed a sleeve 66 in which are cut two elastic tabs 67 and 67a. The member 60 is intended to be housed in a module 69 which has a first elastic tongue 70 with a spout 71, a first stop 72 and a second stop 73. The module 69 comprises a second elastic tongue 70a provided with a stop 74 .
Les languettes élastiques 70 et 70a comportent des bossages 75 et 75a destinés à porter contre le manchon 66 pour parfaitement caler l'organe de contact électrique mâle 60.The elastic tongues 70 and 70a include bosses 75 and 75a intended to bear against the sleeve 66 to perfectly wedge the male electrical contact member 60.
Les extrémités libres des pattes élastiques 67 et 67a sont destinées à porter contre les butées 73 et 74 respectivement tandis que l'épaulement 65 vient coopérer avec la première butée 72.The free ends of the elastic tabs 67 and 67a are intended to bear against the stops 73 and 74 respectively while the shoulder 65 comes to cooperate with the first stop 72.
Le module 69 est destiné à être inséré dans un logement 78 d'un étui 79 qui présente une ouverture 80 pour le passage de la barrette méplate 64. Le module 69 est calé dans l'étui par un ergot 82 I qui coopère avec un crochet 83 dudit étui.The module 69 is intended to be inserted in a housing 78 of a case 79 which has an opening 80 for the passage of the flat bar 64. The module 69 is wedged in the case by a lug 82 I which cooperates with a hook 83 of said case.
Aux figures 9, 10, 11 et 12 on a représenté un oμ- ! til 35 permettant de dégager les organes de contact électrique femelles 1 des canaux 10, pour les remplacer par exemple.Figures 9, 10, 11 and 12 show an oμ-! til 35 allowing the female electrical contact members 1 to be released from the channels 10, for example to replace them.
L'outil 35 comprend un élément en U avec une âme 34, deux ailes 31 et 32, le bord libre de l'aile 31 étant taillé en biseau.The tool 35 comprises a U-shaped element with a core 34, two wings 31 and 32, the free edge of the wing 31 being cut at a bevel.
L'écarte ent des ailes 31 et 32 correspond à la distance entre la paroi lia et le bossage 16a.The distance between the wings 31 and 32 corresponds to the distance between the wall 11a and the boss 16a.
L'outil 35 est engagé de manière que le biseau vienne porter contre le bossage 16a et est poussé afin de soulever la languette élastique 12 (voir figure 10) . En continuant à pousser l'outil 35, l'aile 31 porte contre la patte de retenue élastique 8 et force celle-ci à s'appliquer contre le corps 5 de sorte que ladite patte 8 se trouve écartée de l' épaulement 14 (voir figure 11) .The tool 35 is engaged so that the bevel comes to bear against the boss 16a and is pushed in order to lift the elastic tongue 12 (see FIG. 10). By continuing to push the tool 35, the wing 31 bears against the elastic retaining lug 8 and forces it to be applied against the body 5 so that said lug 8 is spaced from the shoulder 14 (see figure 11).
L'outil 35 est ainsi poussé jusqu'à ce que l'extrémité libre de l'aile 31 vienne porter contre la butée 13, le bec 17 étant alors écarté de l' épaulement 6 (voir figure 12) de sorte que l'organe 1 peut aisément être extrait du canal 10 par l'ouverture 9.The tool 35 is thus pushed until the free end of the wing 31 comes to bear against the stop 13, the spout 17 then being spaced from the shoulder 6 (see FIG. 12) so that the member 1 can easily be extracted from the channel 10 through the opening 9.
La figure 13 montre un outil 90 utilisable avec l'organe de contact électrique 40 de la figure 7. Cet outil affecte une forme en U avec une âme 91 et deux ailes 92 et 93.Figure 13 shows a tool 90 usable with the electrical contact member 40 of Figure 7. This tool affects a U shape with a core 91 and two wings 92 and 93.
L'écarte ent des ailes correspond à la distance séparant les bossages 45 et 45a et les extrémités libres sont taillées en biseau. En engageant l'outil de manière à écarter les languettes élastiques 44 et 44a, on peut aisément dégager l'organe 40.The distance between the wings corresponds to the distance separating the bosses 45 and 45a and the free ends are cut in a bevel. By engaging the tool so as to separate the elastic tongues 44 and 44a, it is easy to disengage the member 40.
La figure 14 montre un outil 100 utilisable pour permettre de retirer de l'étui 69 l'organe de contact électrique mâle 60.FIG. 14 shows a tool 100 which can be used to allow the male electrical contact member 60 to be removed from the case 69.
Cet outil 100 affecte la forme d'un U avec une âme 101 percée d'une fente 102 pour le passage de la barrette 64, et deux ailes 103 et 104 terminées par des biseaux, l'écartement entre les ailes correspondant à l'écartement entre les bossages 75 et 75a. Comme dans les modes de réalisation précédents, on engage les ailes sans les bossages 75, 75a pour, d'une part, écarter les languettes élastiques et, d'autre part, replier les pattes 67, 67a.This tool 100 has the shape of a U with a core 101 pierced with a slot 102 for the passage of the bar 64, and two wings 103 and 104 terminated by bevels, the spacing between the wings corresponding to the spacing between bosses 75 and 75a.
