Description

L'invention vise des éléments de boîtiers de connecteurs électriques.The invention relates to elements of electrical connector housings.

L'invention vise des connecteurs électriques comprenant deux éléments de boîtier, un femelle destiné à recevoir un élément mâle, chaque élément comportant un ou plusieurs canaux destinés, chacun, à recevoir un organe de contact électrique, les organes de contacts électriques de l'un des éléments étant complémentaires de ceux de l'autre et chaque organe de contact électrique étant serti à une extrémité d'un conducteur électrique.The invention relates to electrical connectors comprising two housing elements, a female intended to receive a male element, each element comprising one or more channels each intended to receive an electrical contact member, the electrical contact members of one elements being complementary to those of the other and each electrical contact member being crimped at one end of an electrical conductor.

Après le montage des organes de contacts électriques dans les canaux, on procède, sur l'un ou l'autre ou sur les deux éléments de boîtier, au bouchonnage, c'est-à-dire, qu'on place ceux-ci dans un moule et qu'on injecte de la matière plastique afin de fermer l'extrémité arrière desdits éléments de boîtier, à travers laquelle passe les conducteurs électriques. Une telle manière de procéder est chère, compliquée et nécessite la réalisation de moules adaptés aux différents types de connecteurs.After mounting the electrical contact members in the channels, one proceeds, on one or the other or on the two housing elements, to the plugging, that is to say, that they are placed in a mold and that plastic material is injected in order to close the rear end of said housing elements, through which the electrical conductors pass. Such a procedure is expensive, complicated and requires the production of molds adapted to the different types of connectors.

Le brevet US n° 4 946 398 montre un élément de boîtier qui comporte un dispositif de retenue des organes de contacts électriques, ce dispositif pouvant occuper deux positions; une position d'attente pour la mise en place des organes de contacts électriques et une position de verrouillage. La réalisation de cet élément de boîtier de connecteur nécessite, si on désire obtenir une étanchéité, de procéder à un bouchonnage.US Patent No. 4,946,398 shows a housing element which comprises a device for retaining the electrical contact members, this device being able to occupy two positions; a waiting position for the establishment of the electrical contact members and a locking position. The realization of this connector housing element requires, if one wishes to obtain a seal, to carry out a plugging.

L'un des buts de la présente invention est de permettre un bouchonnage beaucoup plus simple et qui peut être réalisé directement lors du montage des organes de contacts électriques dans les canaux des éléments de boîtier.One of the aims of the present invention is to allow a much simpler plugging and which can be carried out directly during the mounting of the electrical contact members in the channels of the housing elements.

Les éléments de boîtiers de connecteurs électriques, selon l'invention, comprennent un corps présentant, au moins, un canal destiné à recevoir, au moins, un organe de contact électrique serti, à une extrémité, d'un conducteur et comportant dans le canal des moyens de verrouillage dudit organe de contact électrique et un couvercle destiné à être monté sur une extrémité arrière du corps et présentant sur son fond, au moins, un trou pour le passage de l'organe de contact électrique et du conducteur et des moyens d'étanchéité de l'extrémité arrière du corps, ledit couvercle étant en partie rempli d'une matière plastique autocicatrisante et des moyens étant prévus pour maintenir ledit couvercle dans une première position d'attente dans laquelle il est éloigné de l'extrémité arrière du corps et dans laquelle l'organe de contact électrique peut être engagé dans le trou du fond de couvercle à travers la matière autocicatrisante pour être mis en place dans le canal et dans une seconde position de verrouillage dans laquelle, après la mise en place de l'organe de contact, la matière autocicatrisante se trouve comprimée entre le fond du couvercle et l'extrémité arrière dudit corps.The elements of electrical connector housings, according to the invention, comprise a body having, at least, a channel intended to receive, at least, an electrical contact member set at one end with a conductor and comprising in the channel means for locking said electrical contact member and a cover intended to be mounted on a rear end of the body and having on its bottom, at least , a hole for the passage of the electrical contact member and the conductor and sealing means of the rear end of the body, said cover being partly filled with a self-healing plastic material and means being provided for holding said cover in a first waiting position in which it is distant from the rear end of the body and in which the electrical contact member can be engaged in the hole in the bottom of the cover through the self-healing material to be put in place the channel and in a second locking position in which, after the positioning of the contact member, the self-healing material is compressed between the bottom of the cover and the rear end of said body.

Par matière plastique autocicatrisante, on entend une matière susceptible d'être déformée ou perforée et qui tend à revenir dans sa forme initiale.By self-healing plastic material is meant a material capable of being deformed or perforated and which tends to return to its initial shape.

Grâce à l'invention, le couvercle étant dans sa position d'attente, on engage l'organe de contact électrique dans le trou du fond du couvercle, ledit organe perforant la matière autocicatrisante et venant se verrouiller dans le canal puis on pousse le couvercle vers sa position de verrouillage, la matière reprenant sa position initiale en enserrant le conducteur, et en étant enserrée entre l'extrémité arrière du corps et le fond du couvercle pour assurer une fermeture étanche de ladite extrémité arrière.Thanks to the invention, the cover being in its standby position, the electrical contact member is engaged in the hole in the bottom of the cover, said member perforating the self-healing material and coming to lock in the channel then the cover is pushed. towards its locking position, the material returning to its initial position by enclosing the conductor, and being gripped between the rear end of the body and the bottom of the cover to ensure a tight closure of said rear end.

Suivant une caractéristique constructive, le corps comporte sur sa paroi latérale, au moins deux dents dont l'une est située au voisinage de l'extrémité arrière et l'autre décalée vers l'autre extrémité dudit corps, tandis que le couvercle présente une jupe destinée à s'engager sur le corps et dans laquelle est découpée, au moins une languette élastique présentant, sur sa face interne, un crochet destiné à coopérer, sélectivement, avec les dents pour maintenir le couvercle dans les deux positions.According to a constructive characteristic, the body has on its side wall, at least two teeth, one of which is located in the vicinity of the rear end and the other offset towards the other end of said body, while the cover has a skirt intended to engage on the body and in which is cut, at least one elastic tongue having, on its internal face, a hook intended to cooperate, selectively, with the teeth to hold the cover in the two positions.

Enfin, suivant une dernière caractéristique, le canal, du côté de l'extrémité arrière du corps, présente une partie évasée formant rampe, tandis que le couvercle comporte, s'érigeant depuis son fond, une plaquette destinée à coopérer avec la rampe afin d'être guidée vers une extrémité de l'organe de contact.Finally, according to a last characteristic, the channel, on the side of the rear end of the body, has a flared portion forming a ramp, while the cover comprises, erecting from its bottom, a plate intended to cooperate with the ramp in order to 'be guided to one end of the contact member.

Ainsi on assure un verrouillage supplémentaire de l'organe de contact et, de plus si ce dernier n'est pas complètement engagé dans le canal et n'est pas verrouillé lors de l'enfoncement du couvercle vers la position de verrouillage, la plaquette bute contre l'organe de contact et pousse ce dernier vers le fond du canal pour aussi assuré le verrouillage.Thus, an additional locking of the contact member is ensured and, moreover, if the latter is not completely engaged in the channel and is not locked when the cover is pushed towards the locking position, the plate stops. against the contact member and pushes the latter towards the bottom of the channel to also ensure locking.

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

Figure 1 est une vue en perspective éclatée d'un élément de boîtier d'un connecteur, selon l'invention.Figure 1 is an exploded perspective view of a housing element of a connector, according to the invention.

Figure 2 montre, en perspective éclatée, une variante de réalisation de l'invention.Figure 2 shows, in exploded perspective, an alternative embodiment of the invention.

Figures 3, 4 et 5 sont des vues en coupe montrant la mise en place d'un organe de contact électrique dans l'élément de boîtier.Figures 3, 4 and 5 are sectional views showing the establishment of an electrical contact member in the housing member.

Aux différentes figures, on a représenté un élément de boîtier mâle destiné à coopérer avec un élément de boîtier femelle correspondant. Il est évident que l'invention s'applique aussi bien à un élément de boîtier mâle qu'à un élément de boîtier femelle. Egalement dans les modes de réalisation représentés, l'organe de contact électrique est femelle, mais il pourrait parfaitement être mâle ou hermaphrodite. Enfin, l'élément de boîtier imagé sur les dessins est à une voie mais il pourrait parfaitement être à plusieurs voies.In the various figures, there is shown a male housing element intended to cooperate with a corresponding female housing element. It is obvious that the invention applies both to a male housing element and to a female housing element. Also in the embodiments shown, the electrical contact member is female, but it could perfectly well be male or hermaphrodite. Finally, the housing element shown in the drawings is one-way, but it could perfectly well be several-way.

L'élément de boîtier de la figure 1 comprend un corps principal 1 et un couvercle 2. Le corps 1 est cylindrique et présente un canal 3 destiné à recevoir un organe de contact électrique femelle 4 serti à l'extrémité d'un conducteur électrique 5 et présentant, à l'extrémité opposée au conducteur, une pince élastique 6 destinée à recevoir une languette mâle, l'une des parois latérales étant pourvue d'une ouverture 7 pour sa fixation dans le canal 3.The housing element of FIG. 1 comprises a main body 1 and a cover 2. The body 1 is cylindrical and has a channel 3 intended to receive a female electrical contact member 4 crimped at the end of an electrical conductor 5 and having, at the end opposite the conductor, an elastic clamp 6 intended to receive a male tongue, one of the side walls being provided with an opening 7 for fixing it in the channel 3.

L'élément de boîtier de la figure 2 est du même type que celui de la figure 1, sa forme étant parallélépipédique au lieu d'être cylindrique et sur la figure 2, on a reporté les références utilisées pour désigner différents éléments de la figure 1 pour désigner les éléments correspondants de la figure 2, mais affectées de la lettre "a".The housing element of FIG. 2 is of the same type as that of FIG. 1, its shape being parallelepipedal instead of being cylindrical and in FIG. 2, the references used are used to designate different elements of FIG. 1 to designate the corresponding elements of Figure 2, but assigned the letter "a".

Les figures 3, 4 et 5 montrent, en coupe axiale, aussi bien le mode de la figure 1 que celui de la figure 2.FIGS. 3, 4 and 5 show, in axial section, both the mode of FIG. 1 and that of FIG. 2.

Le canal 3 présente, intérieurement, une barrette de verrouillage 8 montée élastiquement et terminée par un crochet 9 destiné à coopérer avec l'ouverture 7.The channel 3 has, internally, a locking bar 8 resiliently mounted and terminated by a hook 9 intended to cooperate with the opening 7.

L'organe 4 est destiné à être engagé par une ouverture d'introduction 11 située à l'extrémité arrière 14 du corps 1 et à buter contre un épaulement 12 au voisinage duquel est pratiquée une fente 13 pour le passage d'une languette mâle (non représentée). Dans cette position, le crochet 9 coopère avec le bord de l'ouverture adjacent à l'épaulement 12 de sorte que l'organe 4 est bloqué.The member 4 is intended to be engaged by an introduction opening 11 situated at the rear end 14 of the body 1 and to abut against a shoulder 12 in the vicinity of which a slot 13 is made for the passage of a male tongue ( not shown). In this position, the hook 9 cooperates with the edge of the opening adjacent to the shoulder 12 so that the member 4 is blocked.

La surface latérale du corps 1 comporte, décalées angulairement de 180°, deux premières dents 16, ces dents étant situées au voisinage de l'extrémité pourvue de l'ouverture d'introduction 11. Sur la surface latérale du corps 1 sont prévues, également, une paire de seconde dents 17 alignées avec les premières dents 16 et décalées vers l'extrémité pourvue de la fente 13.The lateral surface of the body 1 comprises, angularly offset by 180 °, two first teeth 16, these teeth being located in the vicinity of the end provided with the insertion opening 11. On the lateral surface of the body 1 are also provided , a pair of second teeth 17 aligned with the first teeth 16 and offset towards the end provided with the slot 13.

L'ouverture d'introduction 11, du côté de la barrette de verrouillage 8, présente une rampe inclinée 19.The introduction opening 11, on the side of the locking bar 8, has an inclined ramp 19.

Le couvercle 2 présente une jupe 21 avec un fond 24 percé d'un trou central 25.The cover 2 has a skirt 21 with a bottom 24 pierced with a central hole 25.

Dans la jupe 21 sont pratiquées des paires de fentes 22 décalées de 180° et délimitant des languettes élastiques 23.In the skirt 21 are made pairs of slots 22 offset by 180 ° and delimiting elastic tongues 23.

Chaque languette élastique 23 présente, à son extrémité libre et sur sa face interne, un crochet 26 présentant une rampe inclinée 26b et un abrupt 26c.Each elastic tongue 23 has, at its free end and on its internal face, a hook 26 having an inclined ramp 26 b and a steep 26 c .

A partir du fond 24 s'érige une plaquette 28.From the bottom 24 a plate 28 is erected.

Le fond 24 et l'ouverture 25 sont garnis d'une matière plastique ou d'un gel appelé "autocicatrisant" 30, c'est-à-dire, d'une matière qui est souple et élastique et qui permet d'être déformée ou perforée et qui tend à revenir dans sa forme initiale.The bottom 24 and the opening 25 are lined with a plastic material or a gel called "self-healing" 30, that is to say, a material which is flexible and elastic and which allows it to be deformed or perforated and which tends to return to its original shape.

Le couvercle 2 est placé dans une position d'attente, c'est-à-dire, une position dans laquelle les crochets 26 coopèrent avec la paire de premières dents 16, puis l'organe 4 est engagé dans l'ouverture 25 dont la matière 30 est déformée pour permettre le passage dudit organe 4, celui-ci étant poussé jusqu'à ce qu'il vienne dans sa position de verrouillage (voir figure 4) ensuite, le couvercle 2 est poussé afin que les crochets 26 échappent les dents 16 et viennent, par leurs abrupts 26c, coopérer avec les dents 17, le couvercle occupant ainsi une position de verrouillage (voir figure 5).The cover 2 is placed in a waiting position, that is to say, a position in which the hooks 26 cooperate with the pair of first teeth 16, then the member 4 is engaged in the opening 25, the material 30 is deformed to allow passage of said member 4, the latter being pushed until it comes into its locked position (see FIG. 4) then, the cover 2 is pushed so that the hooks 26 escape the teeth 16 and come, by their abrupt 26 c , to cooperate with the teeth 17, the cover thus occupying a locking position (see FIG. 5).

Dans cette position, la matière 30 se trouve comprimée entre l'extrémité du corps 1 adjacente à l'ouverture d'introduction 11, et entoure la partie de sertissage de l'organe 4 et l'extrémité correspondante du conducteur 5 de sorte que l'étanchéité est réalisée.In this position, the material 30 is compressed between the end of the body 1 adjacent to the introduction opening 11, and surrounds the crimping part of the member 4 and the corresponding end of the conductor 5 so that the sealing is achieved.

Lorsqu'on pousse le couvercle depuis la position d'attente (fig. 4) jusqu'à la position de verrouillage (fig. 5), la plaquette 28 coopère avec la rampe 19 et bute contre l'extrémité de la paroi latérale de l'organe 4 de sorte que, si celui-ci n'était parfaitement mis en place, l'engagement du couvercle vers la position de verrouillage assure la mise en position correcte dudit organe 4.When the cover is pushed from the standby position (fig. 4) to the locking position (fig. 5), the plate 28 cooperates with the ramp 19 and abuts against the end of the side wall of the 'member 4 so that, if the latter was not perfectly positioned, the engagement of the cover towards the locking position ensures that said member 4 is put into correct position.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits et représentés. On pourra y apporter de nombreuses modifications dans la limite des revendications.Of course, the invention is not limited to the embodiments which have just been described and shown. Many modifications may be made within the limits of the claims.
