Description

La présente invention concerne un dispositif d'interconnextion électrique.The present invention relates to an electrical interconnection device.

Ce type de dispositif est destiné à réaliser des contacts entre différents composants ou conducteurs électriques. Il peut par exemple faire partie d'un montage électronique ou être intégré dans un connecteur.This type of device is intended to make contacts between different components or electrical conductors. It can for example be part of an electronic assembly or be integrated in a connector.

Ces dispositifs comprennent habituellement un support isolant rigide dans lequel sont montés des éléments conducteurs réalisant le contact désiré. On recherche deux propriétés pour garantir la sûreté du contact : la pression et l'accompagnement. La pression est liée à la force d'appui entre les surfaces de contact, et l'accompagnement est la capacité du contact à se maintenir lors d'un certain déplacement des éléments conducteurs.These devices usually include a rigid insulating support in which are mounted conductive elements making the desired contact. We are looking for two properties to guarantee safe contact: pressure and support. The pressure is linked to the support force between the contact surfaces, and the support is the ability of the contact to be maintained during a certain displacement of the conductive elements.

Pour obtenir ces deux propriétés, les éléments conducteurs du dispositif sont en général montés avec élasticité par rapport au support isolant rigide. Une première possibilité consiste à intercaler des organes élastiques, tels que des ressorts, entre les éléments conducteurs et le support. Ces organes élastiques augmentent le nombre de pièces et donc le coût du dispositif. Ils peuvent en outre poser des problèmes de montage lorsque le dispositif est de petite,dimension. Une autre possibilité consiste à conférer des propriétés élastiques aux éléments conducteurs eux-mêmes. Mais ces propriétés élastiques sont difficiles à réaliser de façon fiable lorsque les éléments conducteurs sont de petite dimension. En outre, ces propriétés élastiques se dégradent après plusieurs connexions et déconnexions des composants.To obtain these two properties, the conductive elements of the device are generally mounted with elasticity with respect to the rigid insulating support. A first possibility consists in interposing elastic members, such as springs, between the conductive elements and the support. These elastic members increase the number of parts and therefore the cost of the device. They can also pose mounting problems when the device is small and large. Another possibility is to give elastic properties to the conductive elements themselves. However, these elastic properties are difficult to achieve reliably when the conductive elements are small. In addition, these elastic properties degrade after several connections and disconnections of the components.

Le but de la présente invention est d'éliminer les inconvénients ci-dessus et de simplifier la structure des dispositifs d'interconnexion connus.The object of the present invention is to eliminate the above drawbacks and to simplify the structure of known interconnection devices.

L'invention propose ainsi un dispositif d'interconnexion électrique, caractérisé en ce qu'il comprend un corps en matière élastique isolante traversé par au moins un conduit, et au moins un élément conducteur introduit dans le conduit pour y établir un contact électrique avec un autre élément conducteur, et en ce que des moyens d'appui, appliqués contre le corps au voisinage du conduit, empêchent la pénétration complète des éléments conducteurs dans le conduit.The invention thus provides an electrical interconnection device, characterized in that it comprises a body of insulating elastic material traversed by at least one conduit, and at least one conductive element introduced into the conduit to establish electrical contact therewith. other conductive element, and in that support means, applied against the body in the vicinity of the conduit, prevent the complete penetration of the conductive elements in the conduit.

Ainsi, le maintien élastique du contact entre les éléments conducteurs est fourni par le corps isolant du dispositif. Si les composants interconnectés électriquement par le dispositif se déplacent légèrement, les moyens d'appui déforment élastiquement le corps au voisinage du conduit, ce qui renforce la pression de contact. La partie de l'élément conducteur située en dehors du conduit peut avoir une forme adaptée à celle des composants à interconnecter, par exemple une forme bombée, si elle est destinée à s'appuyer contre des plages conductrices d'un circuit imprimé ou intégré.Thus, the elastic maintenance of the contact between the conductive elements is provided by the insulating body of the device. If the components electrically interconnected by the device move slightly, the support means elastically deform the body in the vicinity of the duct, which increases the contact pressure. The part of the conductive element situated outside the duct may have a shape adapted to that of the components to be interconnected, for example a curved shape, if it is intended to bear against conductive pads of a printed or integrated circuit.

Dans une version préférée du dispositif selon l'invention, le ou les éléments conducteurs introduits dans le conduit déforment élastiquement le conduit, de préférence la section transversale du conduit.In a preferred version of the device according to the invention, the conductive element or elements introduced into the conduit elastically deform the conduit, preferably the cross section of the conduit.

Cette disposition permet aux éléments conducteurs d'être maintenus dans le corps après l'assemblage du dispositif et avant d'associer le dispositif aux composants à interconnecter.This arrangement allows the conductive elements to be held in the body after assembly of the device and before associating the device with components to be interconnected.

D'autres particularités et avantages de la présente invention apparaîtront dans la description détaillée ci-dessous d'exemples de réalisation, lus conjointement aux dessins annexés, dans lesquels :Other features and advantages of the present invention will appear in the detailed description below of exemplary embodiments, read in conjunction with the appended drawings, in which:

La figure 16 est une vue en plan d'une variante d'élément conducteur utilisable dans le dispositif selon l'invention.Figure 16 is a plan view of an alternative conductive element usable in the device according to the invention.

Les figures 17 et 18 représentent une variante du mode de réalisation représenté aux figures 2 et 3.Figures 17 and 18 show a variant of the embodiment shown in Figures 2 and 3.

En référence à la figure 1, un dispositif selon l'invention comprend un corps 1 en matière élastique isolante. Le corps 1 peut par exemple être une plaque en matière élastomère à base silicone, ayant une épaisseur de l'ordre de quelques millimètres. Le corps 1 est traversé par un ou plusieurs conduits rectilignes 2, ayant par exemple une section circulaire.Referring to Figure 1, a device according to the invention comprises a body 1 of insulating elastic material. The body 1 may for example be a plate of silicone-based elastomer material, having a thickness of the order of a few millimeters. The body 1 is crossed by one or more rectilinear conduits 2, for example having a circular section.

Le dispositif représenté aux figures 1 à 3 comprend deux éléments conducteurs 3 en métal, qui sont introduits dans le conduit 2 par deux faces opposées du corps 1. Dans l'exemple représenté, les deux éléments conducteurs 3 ont une structure identique. Ils comprennent chacun une tige 4 pénétrant dans le conduit 2 et une tête bombée 5 restant à l'extérieur du conduit. Un épaulement 6 est formé entre la tige 4 et la tête 5. Lorsque les éléments conducteurs 3 sont introduits dans le conduit 2, les épaulements 6 viennent prendre appui contre la surface 7 du corps 1 au voisinage du conduit 2.The device shown in Figures 1 to 3 comprises two conductive elements 3 of metal, which are introduced into the duct 2 by two opposite faces of the body 1. In the example shown, the two conductive elements 3 have an identical structure. They each comprise a rod 4 penetrating into the conduit 2 and a domed head 5 remaining outside the conduit. A shoulder 6 is formed between the rod 4 and the head 5. When the conductive elements 3 are introduced into the conduit 2, the shoulders 6 come to bear against the surface 7 of the body 1 in the vicinity of the conduit 2.

La tige 4 de chaque élément conducteur comporte, à son extrémité opposée à la tête 5, une surface de contact 8 inclinée par rapport à la direction de la tige 4. Lorsque les éléments conducteurs 3 sont introduits dans le conduit 2, leurs surfaces de contact respectives 8 sont parallèles entre elles et forment un angle A avec le plan P perpendiculaire à la direction D du conduit 2 (figure 2). Ainsi, lorsque les éléments conducteurs 3 introduits dans le conduit sont poussés axialement l'un vers l'autre, ils tendent à glisser le long de leurs surfaces de contact respectives 8 en maintenant le contact entre ces deux surfaces.The rod 4 of each conductive element comprises, at its end opposite to the head 5, a contact surface 8 inclined relative to the direction of the rod 4. When the conductive elements 3 are introduced into the conduit 2, their contact surfaces respective 8 are parallel to each other and form an angle A with the plane P perpendicular to the direction D of the conduit 2 (Figure 2). Thus, when the conductive elements 3 introduced into the conduit are pushed axially towards one another, they tend to slide along their respective contact surfaces 8 while maintaining contact between these two surfaces.

Comme le montre la figure 1, la tige 4 de chaque élément conducteur 3 a une section transversale supérieure à celle du conduit 2 lorsque les éléments conducteurs 3 n'y sont pas introduits. Ainsi, la présence des éléments conducteurs 3 dans le conduit 2 élargit le conduit 2, ce qui maintient en place les éléments conducteurs 3 après l'assemblage du dispositif (figure 2).As shown in Figure 1, the rod 4 of each conductive element 3 has a cross section greater than that of the conduit 2 when the conductive elements 3 are not introduced there. Thus, the presence of the conductive elements 3 in the conduit 2 widens the conduit 2, which keeps the conductive elements 3 in place after the assembly of the device (FIG. 2).

Aux figures 2 et 3, on a représenté les composants 10 interconnectés au moyen du dispositif. Dans l'exemple représenté, les composants 10 sont interconnectés par l'intermédiaire de plages de contact 11, déposées à leur surface. Les composants 10 peuvent par exemple être des circuits intégrés ou imprimés. Dans la position de fonctionnement représentée à la figure 3, les plages de contact 11 sont appliquées contre les têtes bombées 5 des éléments conducteurs 3 avec une pression axiale. Cette pression axiale déforme élastiquement le corps 1 par l'intermédiaire des épaulements d'appui 6 des éléments conducteurs 3. Les deux conducteurs se désaxent l'un par rapport à l'autre. Ceci déforme davantage encore le conduit. La tendance du conduit à revenir à sa forme de repos assure la pression de contact entre les surfaces de contact 8. La propriété d'accompagnement des contacts résulte de l'inclinaison des surfaces de contact 8 par rapport au plan P transversal à la direction D du conduit 2. Si les composants 10 se déplacent légèrement dans la direction axiale, les éléments conducteurs 3 glissent l'un par rapport à l'autre le long de leurs surfaces de contact 8 respectives en maintenant le contact électrique.In Figures 2 and 3, the components 10 are shown interconnected by means of the device. In the example shown, the components 10 are interconnected by means of contact pads 11, deposited on their surface. The components 10 can for example be integrated or printed circuits. In the operating position shown in Figure 3, the contact pads 11 are applied against the domed heads 5 of the conductive elements 3 with an axial pressure. This axial pressure elastically deforms the body 1 by means of the support shoulders 6 of the conductive elements 3. The two conductors are offset from one another. This further distorts the conduit. The tendency of the duct to return to its rest form ensures the contact pressure between the contact surfaces 8. The accompanying property of the contacts results from the inclination of the contact surfaces 8 relative to the plane P transverse to the direction D of duct 2. If components 10 move slightly in the axial direction, the conductive elements 3 slide relative to each other along their respective contact surfaces 8 while maintaining the electrical contact.

La pression de contact peut être réglée dans une certaine mesure en adaptant l'écartement des deux composants 10 à interconnecter, ou, dans le cas où cet écartement est imposé, en adaptant l'épaisseur du corps élastique 1 et la longueur des éléments conducteurs 3. On peut également varier la pression de contact en modifiant le module d'élasticité de la matière du corps 1.The contact pressure can be adjusted to a certain extent by adapting the spacing of the two components 10 to be interconnected, or, in the case where this spacing is imposed, by adapting the thickness of the elastic body 1 and the length of the conductive elements 3 The contact pressure can also be varied by modifying the modulus of elasticity of the material of the body 1.

L'exemple de réalisation illustré aux figures 4 à 6 diffère de celui illustré aux figures 1 à 3 par la forme des éléments conducteurs 23. Ceux-ci comprennent également une tige 24, une tête bombée 25, et un épaulement d'appui 26 formé entre la tige 24 et la tête 25. En section transversale (figure 6), chaque tige 24 a une forme de demi-cercle délimité par une ligne diamétrale d s'étendant le long des surfaces de contact 28, qui sont planes. Lorsqu'elles sont réunies, les tiges 24 forment, en section transversale, un cercle de diamètre supérieur à celui du conduit 2. Ainsi, lorsqu'on introduit les deux éléments conducteurs 23 dans le conduit 2, ceux-ci élargissent le conduit 2 comme représenté à la figure 4. Ainsi, le serrage élastique radial du conduit sur les éléments conducteurs 23 assure la pression de contact entre les surfaces de contact 28. La condition d'accompagnement est remplie car cette pression se maintient lorsque les surfaces 28 glissent l'une sur l'autre axialement. Pour faciliter l'accostage mutuel des éléments conducteurs 23 lors de leur introduction dans le conduit 2, on peut leur donner des extrémité biseautées 29, comme indiqué en tirets à la figure 4.The embodiment illustrated in FIGS. 4 to 6 differs from that illustrated in FIGS. 1 to 3 by the shape of the conductive elements 23. These also include a rod 24, a domed head 25, and a bearing shoulder 26 formed between the rod 24 and the head 25. In cross section (FIG. 6), each rod 24 has the shape of a semicircle delimited by a diametrical line d extending along the contact surfaces 28, which are planar. When combined, the rods 24 form, in cross section, a circle with a diameter greater than that of the conduit 2. Thus, when the two conductive elements 23 are introduced into the conduit 2, these widen the conduit 2 as shown in Figure 4. Thus, the radial elastic clamping of the conduit on the conductive elements 23 ensures the contact pressure between the contact surfaces 28. The accompanying condition is fulfilled because this pressure is maintained when the surfaces 28 slide the one on the other axially. To facilitate mutual docking of the conductive elements 23 during their introduction into the duct 2, they can be given bevelled ends 29, as indicated in dashes in Figure 4.

Les surfaces de contact 28 des éléments conducteurs 23 sont parallèles à la direction D du conduit 2, c'est-à-dire qu'elles forment un angle droit par rapport au plan P perpendiculaire à la direction D, ce qui garantit un bon accompagnement du contact.The contact surfaces 28 of the conductive elements 23 are parallel to the direction D of the conduit 2, that is to say that they form a right angle with respect to the plane P perpendicular to the direction D, which guarantees good support of the contact.

Les figures 7 à 9 illustrent une autre forme de réalisation de l'invention utilisable lorsque l'un des composants à relier 50 est un composant à broche 51. Aux figures 7 à 9, on a représenté à titre d'exemple deux broches 51 de forme cylindrique, en saillie perpendiculairement à une surface 56 du composant 50. Le dispositif comprend un corps 1 analogue à celui décrit pour les exemples de réalisation précédents, et, pour chaque broche 51, un élément conducteur 43 en métal. Le corps 1 comprend des conduits rectilignes 2 dont la section est voisine de celle des broches 51 et dont les espacements correspondent à ceux des broches 51.FIGS. 7 to 9 illustrate another embodiment of the invention usable when one of the components to be connected 50 is a pin component 51. In FIGS. 7 to 9, two pins 51 of cylindrical shape, projecting perpendicularly to a surface 56 of the component 50. The device comprises a body 1 similar to that described for the previous exemplary embodiments, and, for each pin 51, a conductive element 43 of metal. The body 1 comprises rectilinear conduits 2, the cross section of which is close to that of the pins 51 and the spacings of which correspond to those of the pins 51.

Les éléments conducteurs 43 comprennent une tige 44, une tête 45, et un épaulement d'appui 46 formé entre la tige 44 et la tête 45. La tige 44 a une forme de demi cylindre dont le diamètre intérieur correspond à celui d'une broche 51, et dont le diamètre extérieur est légèrment supérieur à celui du conduit 2. La surface de contact 58 de la broche conductrice 51 est définie par un côté de la forme cylindrique de la broche 51. La surface de contact 48 de l'élément conducteur 43 a une forme concave épousant la forme convexe de la surface de contact 58 de la broche 51. La surface de contact 48 est définie à l'intérieur de la tige 44 par des génératrices parallèles à la direction D du conduit 2.The conductive elements 43 include a rod 44, a head 45, and a support shoulder 46 formed between the rod 44 and the head 45. The rod 44 has the shape of a half cylinder whose internal diameter corresponds to that of a pin 51, and whose outside diameter is slightly greater than that of the conduit 2. The contact surface 58 of the conductive pin 51 is defined by one side of the cylindrical shape of the pin 51. The contact surface 48 of the conductive element 43 has a concave shape matching the convex shape of the contact surface 58 of the spindle 51. The contact surface 48 is defined inside the rod 44 by generatrices parallel to the direction D of the conduit 2.

Pour assembler le dispositif illustré aux figures 7 à 9, on introduit d'abord les éléments conducteurs 43 dans les conduits 2 correspondants, puis on introduit les broches conductrices 51 du composant 50 par la face opposée du corps 1 de manière que l'extrémité des broches 51 viennent en contact avec l'intérieur des tiges 44 (figure 7). Ensuite, lorsqu'on sollicite l'un vers l'autre le composant à broches 50 et le composant à plages conductrices 10, les broches 51 coulissent le long des tiges 44 des éléments conducteurs 43. Les surfaces de contact 48, 58 sont maintenues l'une contre l'autre par l'effort élastique engendré par la déformation du corps 1 résultant d'une part de l'appui des épaulements 46 sur la surface 7 du corps 1 au voisinage des conduits 2, et d'autre part de l'appui de la surface 56 du composant 50 sur la surface opposée 7 du corps 1.To assemble the device illustrated in Figures 7 to 9, the conductive elements 43 are first introduced into the corresponding conduits 2, then the conductive pins 51 of the component 50 are introduced through the opposite face of the body 1 so that the ends of the pins 51 come into contact with the interior rods 44 (Figure 7). Then, when the pin component 50 and the component with conductive pads 10 are urged towards each other, the pins 51 slide along the rods 44 of the conductive elements 43. The contact surfaces 48, 58 are held in place. one against the other by the elastic force generated by the deformation of the body 1 resulting on the one hand from the support of the shoulders 46 on the surface 7 of the body 1 in the vicinity of the conduits 2, and on the other hand from the support of the surface 56 of the component 50 on the opposite surface 7 of the body 1.

Dans la forme de réalisation de l'invention illustrée aux figures 10 à 12, le corps 61 en matière élastique isolante est traversé par un conduit 62 constitué de deux parties rectilignes 62a, 62b formant entre elles un angle qui, dans l'exemple représenté, est égal à 90°. Les parties rectilignes 62a, 62b du conduit 62 débouchent sur deux surfaces adjacentes 67a, 67b du corps 61.In the embodiment of the invention illustrated in FIGS. 10 to 12, the body 61 made of insulating elastic material is traversed by a conduit 62 consisting of two rectilinear parts 62a, 62b forming between them an angle which, in the example shown, is equal to 90 °. The rectilinear parts 62a, 62b of the conduit 62 open onto two adjacent surfaces 67a, 67b of the body 61.

Dans chaque partie rectiligne 62a, 62b du conduit est introduit un élément conducteur 63 ayant la même structure que l'élément conducteur 3 de la forme de réalisation illustrée aux figures 1 à 3. La tige de l'élément conducteur 63 a un diamètre légèrement supérieur à celui de la partie de conduit correspondante. La surface de contact 68 d'un élément conducteur 63 forme un angle d'environ 45° avec le plan Pa, Pb, perpendiculaire à la direction Da, Db de la partie de conduit 62a, 62b correspondante. Ainsi, les surfaces de contact 68 de deux éléments conducteurs 63 sont pratiquement parallèles entre elles lorsque le dispositif est assemblé (figure 11). Le contact électrique entre les éléments conducteurs 63 est établi par les surfaces de contact 68 à l'intersection entre les deux parties rectilignes 62a, 62b du conduit 62.In each rectilinear part 62a, 62b of the conduit is introduced a conductive element 63 having the same structure as the conductive element 3 of the embodiment illustrated in Figures 1 to 3. The rod of the conductive element 63 has a slightly larger diameter to that of the corresponding duct part. The contact surface 68 of a conductive element 63 forms an angle of about 45 ° with the plane Pa, Pb, perpendicular to the direction Da, Db of the corresponding part of the conduit 62a, 62b. So the contact surfaces 68 of two conductive elements 63 are practically parallel to one another when the device is assembled (FIG. 11). The electrical contact between the conductive elements 63 is established by the contact surfaces 68 at the intersection between the two rectilinear parts 62a, 62b of the conduit 62.

Le dispositif illustré aux figures 10 à 12 est utilisé pour interconnecter des composants 10 dont les plages conductrices 11 sont situées dans des plans perpendiculaires entre eux. Pour appliquer les têtes des éléments conducteurs contre les plages de contact 11, on peut prévoir un support rigide en équerre 69 ayant deux surfaces 69c, 69d s'appuyant contre deux surfaces 67c, 67d du corps 61, respectivement opposées aux surfaces 67a, 67b.The device illustrated in Figures 10 to 12 is used to interconnect components 10 whose conductive pads 11 are located in planes perpendicular to each other. To apply the heads of the conducting elements against the contact pads 11, a rigid square support 69 can be provided, having two surfaces 69c, 69d pressing against two surfaces 67c, 67d of the body 61, respectively opposite to the surfaces 67a, 67b.

Dans la forme de réalisation illustrée aux figures 13 à 15, les éléments conducteurs 83 sont identiques à ceux de la forme de réalisation des figures 4 à 6. Le corps 81 en matière élastique isolante de la forme de réalisation des figures 13 à 15 diffère du corps 61 de la forme de réalisation des figures 10 à 12 en ce que les parties rectilignes 82a, 82b du conduit 82 s'étendent au-delà de l'intersection entre ces deux parties rectilignes. Les éléments conducteurs 83 sont introduits dans les parties rectilignes 82a, 82b du conduit de façon que leurs surfaces de contact respectives 88 soient situées dans le plan Q (figure 15) défini par les deux directions des parties rectilignes 82a, 82b du conduit (plan des figures 13 et 14).In the embodiment illustrated in FIGS. 13 to 15, the conductive elements 83 are identical to those of the embodiment of FIGS. 4 to 6. The body 81 made of insulating elastic material of the embodiment of FIGS. 13 to 15 differs from the body 61 of the embodiment of FIGS. 10 to 12 in that the rectilinear parts 82a, 82b of the conduit 82 extend beyond the intersection between these two rectilinear parts. The conductive elements 83 are introduced into the rectilinear parts 82a, 82b of the conduit so that their respective contact surfaces 88 are located in the plane Q (FIG. 15) defined by the two directions of the rectilinear parts 82a, 82b of the conduit (plane of the Figures 13 and 14).

La figure 16 illustre une variante d'un élément conducteur 103 utilisable dans le dispositif lorsqu'un composant à interconnecter comporte des trous destinés à recevoir des broches de contact. L'élément conducteur 103 comprend une tige 104 et une tête 105, un épaulement d'appui 106 étant formé entre la tige 104 et la tête 105. Du côté opposé à l'épaulement 106, la tête 105 comporte une broche 120, destinée au raccordement au composant à interconnecter.FIG. 16 illustrates a variant of a conducting element 103 usable in the device when a component to be interconnected has holes intended to receive contact pins. The conductive element 103 comprises a rod 104 and a head 105, a support shoulder 106 being formed between the rod 104 and the head 105. On the side opposite the shoulder 106, the head 105 comprises a pin 120, intended for the connection to the component to be interconnected.

Dans l'exemple représenté à la figure 16, la tige 104 de l'élément 103 a une extrémité cônique 108 du côté opposé à la tête 105. Une telle forme pointue de l'extrémité 108 facilite l'introduction de l'élément conducteur 103 dans un conduit de section plus faible, comme dans l'exemple des figures 1 à 3 et 10 à 12. En outre cette forme pointue peut permettre de réaliser le conduit en enfonçant les éléments conducteurs 103 dans un corps élastique massif, l'extrémité pointue 108 perforant la matière du corps pour former le conduit qui se comporte ensuite comme les conduits préformés 2, 62, 82 précédemment décrits.In the example shown in Figure 16, the rod 104 of the element 103 has a conical end 108 on the side opposite to the head 105. Such a pointed shape of the end 108 facilitates the introduction of the conductive element 103 in a conduit of smaller cross section, as in the example of FIGS. 1 to 3 and 10 to 12. Furthermore, this pointed shape can make it possible to produce the conduit by driving the conducting elements 103 into a solid elastic body, the pointed end 108 perforating the material of the body to form the conduit which then behaves like the preformed conduits 2, 62, 82 previously described.

Les figures 17 et 18 représentent une variante du mode de réalisation du dispositif représenté aux figures 1 à 3. Selon cette variante, la tige 4 de chacun des deux éléments conducteurs identiques 3 comporte une partie cylindrique prolongée par une extrémité cônique 4a. Lorsque les éléments conducteurs 3 sont introduits dans le conduit 2, leurs surfaces de contact respectives 8 formées par les extrémités côniques 4a sont parallèles entre elles et forment un angle A avec le plan P (figure 17). De la sorte, lorsque les éléments conducteurs 3 introduits dans le conduit 2 sont poussés axialement l'un vers l'autre, ils tendent à glisser le long de leurs surfaces de contact respectives 8 en maintenant le contact entre ces deux surfaces. Le dispositif suivant cette variante de réalisation est en fait le meilleur mode de réalisation et donne entière satisfaction en ce qui concerne les propriétés de pression et d'accompagnement des contacts.Figures 17 and 18 show a variant of the embodiment of the device shown in Figures 1 to 3. According to this variant, the rod 4 of each of the two identical conductive elements 3 comprises a cylindrical part extended by a conical end 4a. When the conductive elements 3 are introduced into the conduit 2, their respective contact surfaces 8 formed by the conical ends 4a are parallel to each other and form an angle A with the plane P (FIG. 17). In this way, when the conductive elements 3 introduced into the conduit 2 are pushed axially towards one another, they tend to slide along their respective contact surfaces 8 while maintaining contact between these two surfaces. The device according to this variant embodiment is in fact the best embodiment and gives whole satisfaction with the pressure and support properties of the contacts.

On a décrit plusieurs formes de réalisation possibles de l'invention, mais on comprendra que diverses modifications peuvent être apportées à ces exemples sans sortir du cadre de l'invention.Several possible embodiments of the invention have been described, but it will be understood that various modifications can be made to these examples without departing from the scope of the invention.

Ainsi, le corps en matière élastique peut prendre diverses formes selon le nombre d'interconnexions à réaliser et la géométrie des composants à interconnecter. Un avantage de la réalisation du corps en matière élastique est qu'on peut lui donner une forme assurant l'étanchéité entre les composants à interconnecter.Thus, the body of elastic material can take various forms depending on the number of interconnections to be made and the geometry of the components to be interconnected. An advantage of the realization of the body in elastic material is that it can be given a shape ensuring the seal between the components to be interconnected.

Le dispositif selon l'invention peut avoir diverses applications. Il peut par exemple être inséré dans un montage électronique pour interconnecter plusieurs circuits intégrés ou imprimés. Il peut également être inséré dans un connecteur pour lui conférer de bonne propriétés de pression de contact, d'accompagnement, et éventuellement d'étanchéité.The device according to the invention can have various applications. It can for example be inserted in an electronic assembly to interconnect several integrated or printed circuits. It can also be inserted into a connector to give it good properties of contact pressure, support, and possibly sealing.
