Description

La présente invention se rapporte à des perfectionnements aux boîtiers de connecteurs électriques.The present invention relates to improvements to electrical connector housings.

L'invention vise des boîtiers de connecteurs formés d'un élément femelle destiné à recevoir un élément mâle, l'un des éléments contenant des organes de connexions électriques mâles ou femelles et l'autre des organes correspondants devant être raccordés.The invention relates to connector housings formed from a female element intended to receive a male element, one of the elements containing male or female electrical connection members and the other of the corresponding members having to be connected.

Afin d'être assuré que les deux éléments de boîtier sont parfaitement accouplés pour que les connexions électriques soient réalisées, on a imaginé différents systèmes.In order to be sure that the two housing elements are perfectly coupled so that the electrical connections are made, various systems have been devised.

Un des systèmes connus est dans la technique surnommée : à "avaloir" c'est-à-dire que lorsque les deux éléments de boîtier sont en partie insérés l'un dans l'autre, un système tend automatiquement à engager à fond l'élément de boîtier mâle dans l'élément de boîtier femelle.One of the known systems is in the technique known as: "downstream", that is to say that when the two housing elements are partly inserted one inside the other, a system automatically tends to fully engage the male housing member in the female housing member.

La présente invention vise un système de ce type qui soit d'un fonctionnement sûr, d'un prix de revient acceptable et d'une utilisation pratique.The present invention relates to a system of this type which is of safe operation, of an acceptable cost price and of practical use.

Le brevet Japonais n° 5 841 745 décrit un connecteur électrique pourvu d'un système de ce type.Japanese Patent No. 5,841,745 describes an electrical connector provided with a system of this type.

Dans ce brevet Japonais l'élément de boîtier mâle comporte une barrette élastique qui bascule à partir de son extrémité destinée à être engagée dans l'élément de boîtier femelle et qui comporte, en un point intermédiaire de sa longueur, une butée destinée à coopérer avec une saillie dudit élément de boîtier.In this Japanese patent, the male housing element comprises an elastic bar which rocks from its end intended to be engaged in the female housing element and which comprises, at an intermediate point of its length, a stop intended to cooperate with a projection of said housing member.

Une telle réalisation présente un certain nombre d'inconvénients.Such an embodiment has a number of drawbacks.

Pour être efficace, il faut, au moment où on tend à effacer la butée pour engager l'élément de boîtier mâle dans l'élément de boîtier femelle, vaincre un point dur à partir duquel le système fonctionne automatiquement.To be effective, it is necessary, at the moment when one tends to erase the stop to engage the male housing element in the female housing element, to overcome a hard point from which the system operates automatically.

Dans le brevet japonais, lorsqu'on appuie sur la barrette élastique, la butée s'efface et on ne sait pas à partir de quelle longueur d'insertion le système fonctionne.In the Japanese patent, when the elastic bar is pressed, the stop disappears and it is not known from which insertion length the system operates.

Pour être assuré que les organes de connexions mâles soient parfaitement insérés dans les organes de connexions femelles, il faut impérativement que lesdits organes de connexions mâles aient une certaine longueur, il est donc indispensable que l'engagement de l'élément de boîtier mâle dans l'élément de boîtier femelle corresponde à une course relativement importante. Si on désire que le système à "avaloir" fonctionne sur la presque totalité de la course il faut, d'une part, que la force de réaction de la barrette élastique soit importante et, d'autre part, que les surfaces en contact de la butée et de la saillie soient les plus réduites possibles.To be sure that the male connection members are perfectly inserted in the female connection members, it is imperative that said male connection members have a certain length, it is therefore essential that the engagement of the male housing element in the 'female housing element corresponds to a relatively large stroke. If it is desired that the "downstream" system works over almost the entire stroke, it is necessary, on the one hand, for the reaction force of the elastic bar to be significant and, on the other hand, that the surfaces in contact with the stop and the projection are as small as possible.

Dans la réalisation décrite dans le brevet japonais, la course est obligatoirement réduite et la force de réaction de la barrette élastique est faible de sorte que les dimensions du boîtier sont réduites.In the embodiment described in the Japanese patent, the stroke is necessarily reduced and the reaction force of the elastic bar is low so that the dimensions of the housing are reduced.

L'un des buts de la présente invention est de remédier à ces divers inconvénients.One of the aims of the present invention is to remedy these various drawbacks.

Les perfectionnements, selon l'invention, visent des boîtiers de connecteurs électriques du type comprenant un élément de boîtier femelle avec une ouverture d'introduction, un élément de boîtier mâle, ces deux éléments étant destinés à recevoir des organes de connexions électriques à accoupler, ledit boîtier étant pourvu d'un système dit à "avaloir" permettant à l'élément mâle d'être engagé à fond et verrouillé automatiquement lorsque l'élément de boîtier mâle a été inséré jusqu'à une position déterminée dans l'élément de boîtier femelle, l'élément de boîtier mâle comportant une languette élastique s'étendant latéralement parallèlement au sens d'introduction de l'élément mâle dans l'élément femelle et solidaire, par une extrémité, de l'élément de boîtier mâle et, par l'autre extrémité, d'un pilier situé au voisinage de l'extrémité de l'élément de boîtier mâle destinée à être engagée dans l'élément femelle, ladite barrette élastique comportant, en un point intermédiaire de sa longueur, une butée, tandis que l'élément de boîtier femelle présente un passage destiné à recevoir la barrette élastique et en un point intermédiaire duquel s'étend une saillie située sur le trajet de la butée, lesdits perfectionnements étant caractérisés en ce que la barrette élastique est inclinée en direction de l'extrémité de l'élément de boîtier mâle opposée à celle destinée à s'insérer dans l'élément de boîtier femelle, la butée affectant la forme d'un bloc sensiblement parallélépipédique, tandis que la saillie présente, tournée du côté de l'ouverture de l'élément de boîtier femelle, un abrupt raccordé à angle droit à une partie elle-même raccordée à angle droit à un abrupt de retenue destiné à assurer, avec la butée, le verrouillage des deux éléments de boîtier entre eux.The improvements according to the invention are aimed at electrical connector housings of the type comprising a female housing element with an introduction opening, a male housing element, these two elements being intended to receive electrical connection members to be coupled, said housing being provided with a so-called "drain" system allowing the male element to be fully engaged and automatically locked when the male housing element has been inserted into a determined position in the housing element female, the male housing element comprising an elastic tongue extending laterally parallel to the direction of introduction of the male element into the female element and secured, at one end, to the male housing element and, by the other end, of a pillar located near the end of the element male housing intended to be engaged in the female element, said elastic bar comprising, at an intermediate point of its length, a stop, while the female housing element has a passage intended to receive the elastic bar and at a point intermediate which extends a projection located on the path of the stop, said improvements being characterized in that the elastic bar is inclined in the direction of the end of the male housing element opposite to that intended to be inserted in the female housing element, the abutment affecting the shape of a substantially parallelepipedal block, while the projection has, turned towards the opening side of the female housing element, a steep connection at right angles to a part itself even connected at right angles to a retaining abrupt intended to ensure, with the stop, the locking of the two housing elements between them.

Grâce à cette disposition, lorsqu'on exerce une pression sur l'élément de boîtier mâle pour l'engager dans l'élément de boîtier femelle, la butée porte contre l'abrupt de la saillie ce qui engendre un ploiement de la partie intermédiaire de la barrette élastique permettant, moyennant un certain effort d'insertion, à la butée de passer sous la saillie.Thanks to this arrangement, when a pressure is exerted on the male housing element to engage it in the female housing element, the stop bears against the steep projection which generates a bending of the intermediate part of the elastic bar allowing, with a certain insertion force, the stop to pass under the projection.

Dès que la butée a légèrement dépassé la saillie, ladite butée porte contre l'angle reliant l'abrupt de retenue à la partie reliant les deux abrupts de sorte qu'avec l'action élastique de la barrette, l'élément de boîtier mâle tend automatiquement à s'engager dans l'élément de boîtier femelle jusqu'à ce que les deux éléments de boîtier soient verrouillés.As soon as the stop has slightly exceeded the projection, said stop bears against the angle connecting the abrupt retaining to the part connecting the two steep so that with the elastic action of the bar, the male housing element tends automatically engage the female housing member until the two housing members are locked.

Suivant un détail constructif, au voisinage de son extrémité adjacente à l'extrémité de l'élément de boîtier mâle, opposée à celle destinée à être engagée dans l'ouverture de l'élément de boîtier femelle, la barrette élastique est solidaire d'un voile dont l'extrémité libre est solidaire d'un barreau transversal relié par deux pattes élastiques à l'extrémité correspondante de l'élément de boîtier mâle.According to a constructive detail, in the vicinity of its end adjacent to the end of the male housing element, opposite to that intended to be engaged in the opening of the female housing element, the elastic bar is integral with a sail whose free end is secured to a transverse bar connected by two legs elastic at the corresponding end of the male housing element.

On réalise ainsi un moyen simple de désaccoupler les deux éléments de boîtier. De plus, l'action élastique de la barrette est renforcée par les pattes élastiques.There is thus provided a simple means of uncoupling the two housing elements. In addition, the elastic action of the bar is reinforced by the elastic tabs.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels :The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the accompanying drawings, in which:

Figure 1 est une vue en perspective schématique d'un connecteur, selon l'invention.Figure 1 is a schematic perspective view of a connector according to the invention.

Figures 2, 3, 4 et 5 sont des vues en coupe montrant le fonctionnement du connecteur, objet de l'invention.Figures 2, 3, 4 and 5 are sectional views showing the operation of the connector, object of the invention.

Le connecteur, représenté aux figures, comprend un élément de boîtier mâle 1 et un élément de boîtier femelle 2 destiné à recevoir l'élément de boîtier 1.The connector, shown in the figures, comprises a male housing element 1 and a female housing element 2 intended to receive the housing element 1.

L'élément de boîtier mâle 1 comporte une série de canaux 3 destinés à recevoir, chacun, un organe de connection électrique femelle relié à un conducteur. Ces organes sont connus et ne sont pas représentés ici.The male housing element 1 comprises a series of channels 3 intended to each receive a female electrical connection member connected to a conductor. These bodies are known and are not shown here.

L'élément de boîtier mâle 1 présente, sur sa surface latérale 4, deux nervures parallèles 3 destinées à coopérer avec des glissières correspondantes 6 de l'élément de boîtier femelle 2.The male box element 1 has, on its lateral surface 4, two parallel ribs 3 intended to cooperate with corresponding slides 6 of the female box element 2.

Au voisinage de l'extrémité 9 destinée à être introduite dans l'élément de boîtier femelle 2, l'élément de boîtier mâle 1, sur sa face 4, comporte deux piliers 7 supportant une barrette élastique 8 dont l'extrémité libre est solidaire d'une extrémité 11 de l'élément de boîtier mâle 1 opposée à l'extrémité 9.In the vicinity of the end 9 intended to be introduced into the female housing element 2, the male housing element 1, on its face 4, comprises two pillars 7 supporting an elastic bar 8 whose free end is integral with one end 11 of the male housing element 1 opposite the end 9.

La barrette élastique 8 est inclinée depuis son extrémité 8a adajacente à l'extrémité 9 vers son extrémité 8b adjacente à l'extrémité 11.The elastic strip 8 is inclined from its end 8a adajacente at the end 9 to its end 8b adjacent to the end 11.

De part et d'autre de l'extrémité 8b de la barrette 8 s'étendent deux pattes élastiques 14 reliées à leur extrémité libre par un barreau 15, lui-même relié par un voile 16 à la barrette élastique 8, cet ensemble constituant un organe de déverrouillage.On either side of the end 8b of the bar 8 extend two elastic tabs 14 connected at their free end by a bar 15, itself connected by a web 16 to the elastic bar 8, this assembly constituting an unlocking member.

La barrette 8, en un point intermédiaire de sa longueur, est solidaire d'une butée 18 affectant la forme d'un bloc parallépipédique.The bar 8, at an intermediate point of its length, is integral with a stop 18 affecting the shape of a parallelepiped block.

Entre les glissières 6, l'élément de boîtier femelle est pourvu d'un passage 20 destiné à recevoir l'ensemble pilier 7 barrette 8.Between the slides 6, the female housing element is provided with a passage 20 intended to receive the pillar assembly 7 bar 8.

Le passage 20 est, en partie, fermé par une saillie 21 située sur le trajet de la butée 18 et qui présente, du côté de l'ouverture d'introduction de l'élément de boîtier mâle, un abrupt 21a raccordé à angle droit à une partie 21b, elle-même raccordée à angle droit à un abrupt de retenue 21c.The passage 20 is partly closed by a protrusion 21 located on the path of the stop 18 and which has, on the side of the insertion opening of the male housing element, an abrupt 21 is connected at right angles to a part 21 b , itself connected at right angles to a steep retaining 21 c .

Le fond de l'élément de boîtier femelle 2 est pourvu d'organes mâles 24 destinés à coopérer avec les organes femelles des canaux 3.The bottom of the female housing element 2 is provided with male members 24 intended to cooperate with the female members of the channels 3.

Le fonctionnement est le suivant :The operation is as follows:

On engage l'élément 1 dans l'élément 2, les nervures 5 viennent coopérer avec les glissières 6, tandis que les piliers 7 et l'extrémité 8a s'insèrent dans le passage 20 (voir figure 2) jusqu'à ce que la butée 18 vienne porter contre l'abrupt 21a.The element 1 is engaged in the element 2, the ribs 5 come to cooperate with the slides 6, while the pillars 7 and the end 8 a are inserted in the passage 20 (see FIG. 2) until the stop 18 comes to bear against the abrupt 21 a .

En continuant d'essayer d'engager l'élément 1 dans l'élément 2, la barrette élastique 8 ploie depuis son extrémité 8a jusqu'à son extrémité 8b et ainsi (voir figures 2 et 4) l'extrémité de la butée 18 tournée du côté des piliers vient passer sous la partie 21b. Compte tenu de la force de réaction de la barrette 8, il est nécessaire d'exercer une légère pression jusqu'à ce que ladite extrémité de la butée ait franchi l'arête séparant 21b et 21c. Lorsque cette partie angulaire a été dépassée compte tenu de l'action élastique de la barrette 8 qui tend à revenir dans sa position initiale, l'élément de boîtier 1 est automatiquement déplacé (dans le sens de la flèche a voir figure 4) pour s'engager complètement dans l'élément de boîtier 2, la butée 18 venant alors coopérer avec l'abrupt de retenue 21c pour assurer le verrouillage des éléments de boîtier entre eux (voir figure 5).Continuing to try to engage element 1 in element 2, the elastic bar 8 bends from its end 8 a to its end 8 b and thus (see Figures 2 and 4) the end of the stop 18 turned towards the pillars comes under part 21 b . Given the reaction force of the bar 8, it is necessary to exert a slight pressure until said end of the stop has crossed the edge separating 21b and 21c. When this angular part has been exceeded, taking into account the elastic action of the bar 8 which tends to return to its initial position, the housing element 1 is automatically moved (in the direction of the arrow a see FIG. 4) to s 'fully engage in the housing element 2, the stopper 18 then cooperating with the retaining abutment 21c to ensure the locking of the housing elements between them (see FIG. 5).

Pour désaccoupler les éléments de boîtier 1 et 2, il suffit d'exercer (voir figure 5) une pression sur le barreau 5 dans le sens de la flèche b afin de dégager la butée 18 de la saillie 21 et de tirer l'élément 1 dans le sens opposé à la flèche a.To decouple the housing elements 1 and 2, it is enough to exert (see figure 5) a pressure on the bar 5 in the direction of the arrow b in order to release the stop 18 from the projection 21 and to pull the element 1 in the direction opposite to the arrow a.

De préférence, les organes de connexions électriques peuvent avoir des longueurs telles qu'ils ne coopèrent que lorsque la butée 18 coopère avec la partie angulaire reliant l'abrupt 21c à la partie 21b et qu' ainsi on est sûr que les éléments de boîtier s'assembleront l'un dans l'autre.Preferably, the electrical connection members may have lengths such that they cooperate only when the stopper 18 cooperates with the angular part connecting the abrupt 21 c to the part 21 b and that it is thus certain that the elements of housing will fit together.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the embodiment which has just been described and shown. Many detailed modifications can be made without departing from the scope of the invention.
