L'invention vise, plus particulièrement, un connecteur électrique du type décrit dans la demande de brevet au nom de la demanderesse n° 92.09298 du 28 Juillet 1992 et publiée sous le n° FR-A-2 694 454.The invention relates, more particularly, to an electrical connector of the type described in the patent application in the name of the applicant n ° 92.09298 of July 28, 1992 and published under n ° FR-A-2 694 454.

Le connecteur décrit dans cette demande comprend un élément de boîtier présentant à une extrémité un logement pour recevoir un élément de boîtier femelle, ledit élément de boîtier comportant deux conduits parallèles s'étendant perpendiculairement au logement et destinés à recevoir, chacun, une branche d'une clé pourvue de rampes, tandis que l'un des éléments présente des tétons destinés à coopérer avec lesdites rampes.The connector described in this application comprises a housing element having at one end a housing for receiving a female housing element, said housing element comprising two parallel conduits extending perpendicular to the housing and intended to each receive a branch of a key provided with ramps, while one of the elements has pins intended to cooperate with said ramps.

Dans un mode de réalisation décrit dans cette demande, il est prévu un joint élastique constitué par un manchon monté sur une jupe de l'élément de boîtier mâle et qui vient s'insérer entre la paroi latérale interne d'une cavité de l'élément de boîtier femelle et ladite jupe, ledit joint comportant une série de tores parallèles destinés à coopérer avec la surface latérale interne de l'élément de boîtier femelle.In an embodiment described in this application, there is provided an elastic seal constituted by a sleeve mounted on a skirt of the male housing element and which is inserted between the internal lateral wall of a cavity of the element of female housing and said skirt, said seal comprising a series of parallel tori intended to cooperate with the internal lateral surface of the female housing element.

On a constaté qu'un tel joint ne donnait pas une entière satisfaction.It was found that such a seal was not entirely satisfactory.

L'un des buts de la présente invention est de perfectionner un tel joint afin d'améliorer l'étanchéité.One of the aims of the present invention is to perfect such a seal in order to improve the seal.

L'objet de la présente invention est relatif à un connecteur électrique comprenant d'une part, un joint et d'autre part, un élément de boîtier mâle présentant à une extrémité, un logement destiné à recevoir un élément de boîtier femelle, présentant une cavité, le logement étant fermé par un fond et comportant intérieurement une jupe destinée à s'insérer dans la cavité, ledit élément de boîtier mâle comportant deux conduits parallèles s'étendant perpendiculairement à l'élément de boîtier femelle et destinés à recevoir, chacun, une branche d'une clé, chaque branche présentant deux rampes inclinées destinées à coopérer avec des tétons de l'élément de boîtier femelle, chaque rampe étant terminée par un cran formé par un creusage de manière que le coulissement de la clé, dans un sens, provoque l'engagement de l'élément de boîtier femelle dans le logement jusqu'à une position de verrouillage dans laquelle les tétons coopèrent avec les crans, le joint étant formé par un manchon élastique présentant des tores à sa périphérie, ledit joint étant monté sur ladite jupe de manière que lesdits tores coopèrent avec la surface interne de la cavité de l'élément de boîtier femelle, le connecteur étant caractérisé en ce que le joint présente à une extrémité, un rebord latéral destiné à porter contre le fond du logement à partir duquel s'étend la jupe et en ce que ce rebord est pourvu d'ondulations qui augmentent l'élasticité du rebord et améliorent ainsi le verrouillage de la clé.The object of the present invention relates to an electrical connector comprising on the one hand, a seal and on the other hand, a male housing element having at one end, a housing intended to receive a female housing element, having a cavity, the housing being closed by a bottom and internally comprising a skirt intended to be inserted into the cavity, said male housing element comprising two parallel conduits extending perpendicularly to the female housing element and intended to each receive a branch of a key, each branch having two inclined ramps intended to cooperate with pins of the female housing element, each ramp being terminated by a notch formed by a digging so that the sliding of the key, in one direction, causes the engagement of the female housing element in the housing to a locking position in which the pins cooperate with the notches, the seal being formed by an elastic sleeve having tori at its periphery, said seal being mounted on said skirt so that said tori cooperate with the internal surface of the cavity of the female housing element, the connector being characterized in that the seal has a end, a lateral rim intended to bear against the bottom of the housing from which the skirt extends and in that this rim is provided with corrugations which increase t the elasticity of the rim and thus improve the locking of the key.

Grâce à une telle disposition, on améliore l'étanchéité.Thanks to such an arrangement, the sealing is improved.

L'invention va maintenant être décrite avec plus de détail 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 et figure 2 sont des vues en perspective d'un joint, selon l'invention.Figure 1 and Figure 2 are perspective views of a seal according to the invention.

Figure 3 est une vue en perspective éclatée du connecteur selon l'invention destiné à recevoir le joint des figures 1 et 2.FIG. 3 is an exploded perspective view of the connector according to the invention intended to receive the joint of FIGS. 1 and 2.

Figure 4 est une vue en coupe suivant la ligne 4-4 de la figure 5.Figure 4 is a sectional view along line 4-4 of Figure 5.

Figure 5 est une vue en coupe suivant la ligne 5-5 de la figure 4.Figure 5 is a sectional view along line 5-5 of Figure 4.

Figure 6 est une vue correspondant à la figure 4, la clé étant verrouillée.Figure 6 is a view corresponding to Figure 4, the key being locked.

Figure 7 est une vue correspondant à la figure 5, la clé étant verrouillée.Figure 7 is a view corresponding to Figure 5, the key being locked.

Figure 8 et figure 9 sont des vues schématiques montrant le verrouillage du module femelle.Figure 8 and Figure 9 are schematic views showing the locking of the female module.

Le connecteur, représenté à la figure 3, comprend un élément de boîtier mâle 1 destiné, par une extrémité, à recevoir un module mâle 2 et, par l'autre extrémité, un élément de boîtier femelle 3, ledit élément 1 comportant, montée coulissante, une clé de verrouillage 4.The connector, shown in FIG. 3, comprises a male housing element 1 intended, at one end, to receive a male module 2 and, by the other end, a female housing element 3, said element 1 comprising, sliding mounted , a locking key 4.

L'élément 1 comporte une première partie 10 destinée à recevoir le module mâle 2 et un logement 11 destiné à recevoir l'élément de boîtier femelle 3 et la clé 4.The element 1 comprises a first part 10 intended to receive the male module 2 and a housing 11 intended to receive the element of female housing 3 and the key 4.

Le module mâle 2 est divisé en compartiments 13 dans chacun desquels est logé un organe de contact électrique femelle 14 et prolongé par une partie 18.The male module 2 is divided into compartments 13 in each of which is housed a female electrical contact member 14 and extended by a part 18.

La partie 10 présente une cavité 15 avec un fond 16 dans la partie centrale duquel s'étend une jupe 17 correspondant à la partie inférieure 18 du module mâle 2 afin de recevoir celle-ci.Part 10 has a cavity 15 with a bottom 16 in the central part of which extends a skirt 17 corresponding to the lower part 18 of the male module 2 in order to receive the latter.

Le logement 11 du boîtier 1 affecte une forme générale parallélépipédique avec deux parois longitudinales 20 et 21 et deux parois transversales 22 et 23.The housing 11 of the housing 1 has a generally parallelepiped shape with two longitudinal walls 20 and 21 and two transverse walls 22 and 23.

Dans les parois transversales 22 et 23 s'ouvrent deux conduits 24 qui présentent des épaulements 26.In the transverse walls 22 and 23 two conduits 24 open which have shoulders 26.

Dans le bord inférieur des parois 20 et 21 sont pratiquées des fentes 30 pour le passage de tétons 31 prévus sur les parois latérales longitudinales 39 du module 3.In the lower edge of the walls 20 and 21 are made slots 30 for the passage of pins 31 provided on the longitudinal side walls 39 of the module 3.

L'élément de boîtier femelle 3 est constitué d'un corps en matière plastique moulé qui présente un fond 33 à partir duquel s'érigent des languettes mâles 34 destinées à s'insérer dans les organes femelles 14.The female housing element 3 consists of a molded plastic body which has a bottom 33 from which erect male tongues 34 intended to be inserted into the female organs 14.

Le corps présente une cavité 36 divisée en deux parties, une partie 36a située au voisinage du bord libre et une partie 36b située au voisinage du fond 33 plus petite que la partie 36a et raccordée à celle-ci par un épaulement 38.The body has a cavity 36 divided into two parts, a part 36 a located in the vicinity of the free edge and a part 36 b situated in the vicinity of the bottom 33 smaller than the part 36 a and connected to the latter by a shoulder 38.

Les tétons 31 sont, en partie, bordés par un bourrelet 40.The pins 31 are, in part, bordered by a bead 40.

La clé 4 est constituée par un corps en matière plastique moulée présentant une section en U avec deux branches 45 et une âme 46.The key 4 is constituted by a molded plastic body having a U-shaped section with two branches 45 and a core 46.

L'écartement des branches 45 correspond à l'écartement des conduits 24.The spacing of the branches 45 corresponds to the spacing of the conduits 24.

Chaque branche comporte des rainures 47 afin de coopérer avec les épaulements 26.Each branch has grooves 47 in order to cooperate with the shoulders 26.

Chaque branche 45 présente deux rampes inclinées 48 qui, à l'extrémité inférieure, débouchent dans des échancrures 49, tandis que l'extrémité supérieure se termine par une partie 50 pourvue d'un cran 51 formé par un creusage s'étendant en direction du bord pourvu des échancrures 49.Each branch 45 has two inclined ramps 48 which, at the lower end, open into notches 49, while the upper end ends in a part 50 provided with a notch 51 formed by a hollow extending in the direction of the edge provided with notches 49.

On conçoit que, lorsqu'on met en place le module 3, les tétons 31 traversent les fentes 30, s'insèrent dans les échancrures 49 et que, lorsqu'on pousse la clé 4, les tétons 31, en coopérant avec les rampes 48, provoquent l'engagement du module femelle dans le logement 11.It is understood that, when the module 3 is put in place, the pins 31 pass through the slots 30, are inserted into the notches 49 and that, when the key 4 is pushed, the pins 31, by cooperating with the ramps 48, cause the female module to engage in the housing 11.

Le joint représenté aux figures 1 et 2 est constitué par un manchon 60 en une matière souple et élastique présentant, sur sa surface latérale, une série de tores 61 et dont l'une des extrémités est terminée par un rebord 62 qui présente des ondulations 63.The seal shown in Figures 1 and 2 consists of a sleeve 60 of a flexible and elastic material having, on its lateral surface, a series of toroids 61 and one of the ends of which ends in a flange 62 which has undulations 63 .

Le joint est destiné à être monté sur la jupe 17, le rebord 62 venant buter contre la surface externe du fond 16.The seal is intended to be mounted on the skirt 17, the rim 62 abutting against the external surface of the bottom 16.

Lorsqu'on pousse la clé 4 pour verrouiller l'élément de boîtier 3, celui-ci s'engage dans la cavité 11, tandis que le joint 60 vient coopérer par ses tores 61 avec la partie 36a de la cavité 36, le bord libre dudit élément 3 comprimant le rebord 62 dont les ondulations 63 augmentent l'élasticité. Ainsi les tétons 31 tendent à être maintenus dans les crans 51.When the key 4 is pushed to lock the housing element 3, it engages in the cavity 11, while the seal 60 comes to cooperate by its toroids 61 with the part 36a of the cavity 36, the free edge of said element 3 compressing the rim 62 whose undulations 63 increase the elasticity. Thus the pins 31 tend to be held in the notches 51.

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 défini par la revendication.Of course, the invention is not limited to the embodiment which has just been described and shown. Many modifications of detail can be made without departing from the scope of the invention defined by the claim.
