Un ensemble de connexion du type précité est connu du brevet des Etats-Unis US-5 167 531, dans lequel les deux éléments de connexion superposés sont logés dans un corps métallique moulé dont la face avant présente des ouvertures recevant des profils rectangulaires avant des éléments de connexion. Le corps métallique comporte des parois latérales qui servent en particulier de moyen de rétention du boîtier de blindage inséré verticalement.A connection assembly of the aforementioned type is known from United States patent US Pat. No. 5,167,531, in which the two superimposed connection elements are housed in a molded metal body, the front face of which has openings receiving rectangular profiles before the elements. of connection. The metal body has side walls which serve in particular as a means of retaining the shielding box inserted vertically.

Une telle structure permet de réaliser un ensemble de connexion entièrement monté. L'espacement entre les deux éléments de connexion superposés est déterminé par les logements de la face avant du boîtier métallique moulé.Such a structure makes it possible to produce a fully assembled connection assembly. The spacing between the two superimposed connection elements is determined by the housings on the front face of the molded metal housing.

Il n'est par contre pas possible de réaliser des sous-ensembles.However, it is not possible to produce sub-assemblies.

Le brevet des Etats-Unis, US-5 044 984 concerne également un ensemble de connexion pour des éléments de connexion superposés. Sa construction est compliquée car elle met en oeuvre des éléments d'écartement massifs présentant des formes tout à fait spécifiques, et nécessite en outre des éléments supplémentaires (désignés par le repère 108) absolument nécessaires pour obtenir la rigidité de l'ensemble.The United States patent, US-5,044,984 also relates to a connection assembly for superimposed connection elements. Its construction is complicated because it implements massive spacing elements having very specific shapes, and also requires additional elements (designated by the reference 108) absolutely necessary to obtain the rigidity of the assembly.

La présente invention a pour objet un ensemble de connexion qui permette la réalisation de sous-ensembles, notamment modulaires, mais qui présente une structure simple et qui en outre ne nécessite qu'un minimum de modifications des éléments de connexion pour arriver au résultat recherché.The present invention relates to a connection assembly which allows the production of sub-assemblies, in particular modular, but which has a simple structure and which also requires only a minimum of modifications of the connection elements to achieve the desired result.

L'invention concerne ainsi un ensemble de connexion présentant au moins deux éléments de connexion superposés, respectivement supérieur et inférieur, présentant chacun un boîtier, un corps central isolant logé dans le boîtier, et une pluralité de contacts coudés disposés dans le corps central isolant ainsi que des éléments de superposition pour maintenir les deux éléments de connexion dans une position nominale de superposition donnée, caractérisé en ce que les éléments de superposition sont constitués par des plaques comprenant une partie supérieure comprenant au moins un premier élément de maintien solidaire de l'élément de connexion supérieur par insertion à force et une partie inférieure comprenant au moins un deuxième élément de maintien solidaire de l'élément de connexion inférieur par insertion à force.The invention thus relates to a connection assembly having at least two superposed connection elements, respectively upper and lower, each having a housing, an insulating central body housed in the housing, and a plurality of elbow contacts arranged in the insulating central body thus as overlapping elements for holding the two connection elements in a given nominal superposition position, characterized in that the overlapping elements consist of plates comprising an upper part comprising at least a first holding element integral with the element upper connection by force insertion and a lower part comprising at least a second holding element integral with the lower connection element by force insertion.

Le premier élément de maintien d'au moins une plaque peut avantageusement présenter un ergot inséré à force dans une ouverture correspondante du boîtier de l'élément de connexion supérieur.The first element for holding at least one plate may advantageously have a lug inserted by force into a corresponding opening in the housing of the upper connection element.

La partie supérieure d'au moins une plaque peut avantageusement présenter une première région en butée sur un bord du boîtier de l'élément de connexion supérieur.The upper part of at least one plate may advantageously have a first region in abutment on an edge of the housing of the upper connection element.

La partie inférieure d'au moins une plaque peut présenter une deuxième région en butée sur un bord du boîtier de l'élément de connexion inférieur.The lower part of at least one plate may have a second region in abutment on an edge of the housing of the lower connection element.

Selon un mode de réalisation particulièrement avantageux, la première région forme butée dans le sens horizontal alors que la deuxième région forme butée au moins dans le sens vertical. Ceci permet d'assurer la rigidité d'ensemble tout en permettant un montage facile des plaques par insertion à force.According to a particularly advantageous embodiment, the first region forms a stop in the direction horizontal while the second region forms a stop at least in the vertical direction. This ensures overall rigidity while allowing easy mounting of the plates by force insertion.

Le deuxième élément de maintien d'au moins une plaque peut présenter un deuxième ergot inséré à force dans une ouverture du boîtier de l'élément de connexion inférieur.The second element for holding at least one plate may have a second lug inserted by force into an opening in the housing of the lower connection element.

La partie inférieure d'au moins une plaque peut présenter un troisième élément de maintien présentant une extrémité de maintien s'étendant au-delà d'une face inférieure du boîtier de l'élément de connexion inférieur de manière à permettre une fixation à travers une ouverture d'un support.The lower part of at least one plate may have a third retaining element having a retaining end extending beyond a lower face of the housing of the lower connection element so as to allow fixing through a opening of a support.

L'élément de maintien peut traverser l'ouverture du boîtier de l'élément de connexion inférieur.The holding member can pass through the opening of the housing of the lower connecting member.

Ledit support est avantageusement un circuit imprimé auquel au moins certains desdits contacts coudés sont raccordés électriquement.Said support is advantageously a printed circuit to which at least some of said bent contacts are electrically connected.

L'invention concerne également un élément de superposition pour ensemble de connexion du type présentant au moins deux éléments de connexion superposés, respectivement supérieur et inférieur, caractérisé en ce qu'il comporte une plaque présentant une partie supérieure comprenant au moins un premier élément de maintien susceptible d'être solidarisé avec ledit élément de connexion supérieur par insertion à force, et une partie inférieure comprenant au moins un deuxième élément de maintien susceptible d'être solidarisé avec ledit élément de connexion inférieur par insertion à force.The invention also relates to a superimposing element for a connection assembly of the type having at least two superposed connection elements, respectively upper and lower, characterized in that it comprises a plate having an upper part comprising at least a first holding element. capable of being secured to said upper connection element by force insertion, and a lower part comprising at least a second holding element capable of being secured to said lower connection element by force insertion.

D'autres caractéristiques et avantages de l'invention apparaîtront mieux à la lecture de la description qui va suivre, donnée à titre d'exemple non limitatif, en liaison avec les dessins qui représentent :

  • la figure 1a, une vue de dessus d'un ensemble de connexion selon un mode de réalisation préféré de l'invention,
  • la figure 1b, une coupe selon B-B de la figure la,
  • la figure 1c, une coupe selon A-A de la figure la,
  • la figure 2, une vue en perspective d'un des éléments de connexion mis en oeuvre dans les figures 1a à 1c.
Other characteristics and advantages of the invention will appear better on reading the description which follows, given by way of example limiting, in conjunction with the drawings which represent:
  • FIG. 1a, a top view of a connection assembly according to a preferred embodiment of the invention,
  • FIG. 1b, a section along BB of FIG. la,
  • FIG. 1c, a section along AA of FIG. la,
  • Figure 2, a perspective view of one of the connection elements used in Figures 1a to 1c.

Selon les figures, on voit que deux éléments de connexion référencés 1 et 2 sont superposés, l'élément 1 présentant un boîtier 28 présentant une partie avant 32, et dans lequel est disposé un corps isolant 11 dans les ouvertures duquel sont disposés des contacts du type femelle 50 qui se prolongent vers l'arrière tout d'abord par une région longitudinale 51, une région inclinée à 45° 52 et une région de terminaison 53 perpendiculaire à la région 51 qui se prolonge par des extrémités de contact 56 destinés à être encliquetées dans des ouvertures 72 d'un circuit imprimé 70, éventuellement à travers une plaque de maintien 71. L'élément de connexion inférieur 2 présente, de la même manière un boîtier 28 dans lequel est disposé un corps isolant 11, l'ouverture 16 dans laquelle sont disposés des contacts 50, ici du type femelle, qui se prolongent vers l'arrière tout d'abord par une région longitudinale 54, puis par une région 55 coudée à 90° par rapport à la région 54 se prolongeant par des terminaisons de contact 56 destinés à être encliquetées dans des ouvertures 72 d'un circuit imprimé 70.According to the figures, it can be seen that two connection elements referenced 1 and 2 are superimposed, the element 1 having a housing 28 having a front part 32, and in which is arranged an insulating body 11 in the openings of which are arranged contacts of the female type 50 which extend backwards firstly by a longitudinal region 51, a region inclined at 45 ° 52 and a termination region 53 perpendicular to the region 51 which is extended by contact ends 56 intended to be snapped into openings 72 of a printed circuit 70, possibly through a retaining plate 71. The lower connection element 2 likewise has a housing 28 in which an insulating body 11 is arranged, the opening 16 in which are arranged contacts 50, here of the female type, which extend towards the rear first by a longitudinal region 54, then by a region 55 bent at 90 ° by relative to the region 54 extending by contact terminations 56 intended to be snapped into openings 72 of a printed circuit 70.

Comme le montre plus particulièrement la figure 2 dans laquelle les éléments de connexion 1 et 2 sont représentés avec enlèvement des contacts, le corps central isolant 11 est maintenu en position par une rampe 5 formant butée pour la région d'extrémité en forme de poutre 5' du corps isolant 11. La partie avant de l'élément de connexion présente, à ses extrémités longitudinales, des prolongements 26 encliquetables en 27 dans une plaque avant non représentée, laquelle présente une ouverture pour recevoir la partie avant rectangulaire 32' du boîtier 28.As shown more particularly by FIG. 2 in which the connection elements 1 and 2 are shown with the contacts removed, the insulating central body 11 is held in position by a ramp 5 forming a stop for the beam-shaped end region 5 ′ of the insulating body 11. The front part of the connection element has, at its longitudinal ends, extensions 26 which snap into place 27 in a front plate, not shown, which has an opening for receiving the rectangular front part 32 'of the housing 28.

A l'arrière des éléments de connexion 1 et 2, et aux extrémités longitudinales du boîtier 28, sont disposées deux régions formant trièdre 22, 24, 25. La paroi la plus interne de ce trièdre est verticale et est référencée 22. Elle porte la rampe 5 ainsi que deux ouvertures en forme de U 23, l'une supérieure et l'autre inférieure, disposées près de l'arrière de la paroi 22. La paroi horizontale 24 du trièdre présente, d'une part une ouverture 24', d'autre part une ouverture 30, située entre l'ouverture 24' et la paroi verticale 25 du trièdre, et enfin, une fente verticale 39 disposée à l'arrière de la paroi 24. La fente et l'ouverture 24' et 30 ont avantageusement un axe commun. Enfin, la paroi verticale 25 du trièdre présente une ouverture circulaire 25'. On notera que les ouvertures 24' et 25' existent déjà dans les connecteurs de ce type.At the rear of the connection elements 1 and 2, and at the longitudinal ends of the housing 28, are arranged two regions forming a trihedron 22, 24, 25. The innermost wall of this trihedron is vertical and is referenced 22. It carries the ramp 5 as well as two U-shaped openings 23, one upper and the other lower, arranged near the rear of the wall 22. The horizontal wall 24 of the trihedron has, on the one hand an opening 24 ', on the other hand an opening 30, located between the opening 24 'and the vertical wall 25 of the trihedron, and finally, a vertical slot 39 disposed at the rear of the wall 24. The slot and the opening 24' and 30 advantageously have a common axis. Finally, the vertical wall 25 of the trihedron has a circular opening 25 '. Note that the openings 24 'and 25' already exist in connectors of this type.

Comme le montrent plus particulièrement les figures 1a et 1c, les éléments 1 et 2 sont maintenus dans leur position de superposition par deux plaques 40 qui sont substantiellement planes et disposées chacune à une extrémité longitudinale des boîtiers 28. Chacune des plaques présente ainsi à une extrémité supérieure 47, d'une part, un prolongement 33 susceptible d'être inséré à force par la partie inférieure du trou 30 de la paroi de trièdre 24 et un prolongement arrière 42 venant se loger à force au fond 43 d'une rainure verticale 39.As shown more particularly in FIGS. 1a and 1c, the elements 1 and 2 are held in their superposition position by two plates 40 which are substantially planar and each disposed at a longitudinal end of the housings 28. Each of the plates thus has at one end upper 47, on the one hand, an extension 33 capable of being force-fitted through the lower part of the hole 30 of the trihedral wall 24 and a rear extension 42 coming to be forced into the bottom 43 of a vertical groove 39.

A la partie inférieure, la plaque est également positionnée d'une part par le doigt ou ergot 31 inséré à force dans l'ouverture 30, et par le prolongement 29 inséré à force dans une rainure verticale 39 permettant de former butée dans le sens latéral. En outre, un prolongement 46 peut venir s'appuyer à la partie supérieure du boîtier 28, et en particulier il peut être logé dans une rainure 146 permettant de former butée dans le sens latéral.In the lower part, the plate is also positioned on the one hand by the finger or lug 31 inserted by force into the opening 30, and by the extension 29 inserted by force in a vertical groove 39 making it possible to form a stop in the lateral direction . In addition, an extension 46 can come to bear on the upper part of the housing 28, and in particular it can be housed in a groove 146 making it possible to form a stop in the lateral direction.

La plaque 40 dont la partie inférieure 48 borde le bord supérieur de la portion de trièdre 24 permet, non seulement de maintenir un écart vertical entre les éléments 1 et 2, mais aussi, de positionner ceux-ci dans les autres directions tout en conférant au montage un caractère de sous-ensemble modulaire.The plate 40, the lower part 48 of which borders the upper edge of the trihedron portion 24 makes it possible not only to maintain a vertical distance between the elements 1 and 2, but also to position them in the other directions while giving the mounting a modular subset character.

Le boîtier 28 du connecteur est maintenu d'une part verticalement en raison du fait que, son ergot 33 étant emmanché à force dans l'ouverture 30, le bord supérieur 41 de la plaque longe la face inférieure de la portion de trièdre 24, d'autre part dans une position avant-arrière par le fait que le boîtier 28 est pris entre le prolongement ou ergot 33 et le prolongement 42, et enfin, angulairement dans un plan horizontal en raison de la présence des deux rainures 39 et des deux rainures 146 qui emprisonnent les prolongements 29 et 42.The housing 28 of the connector is held vertically on the one hand due to the fact that, its lug 33 being force fitted into the opening 30, the upper edge 41 of the plate runs along the lower face of the portion of trihedron 24, d 'other hand in a front-rear position by the fact that the housing 28 is caught between the extension or lug 33 and the extension 42, and finally, angularly in a horizontal plane due to the presence of the two grooves 39 and the two grooves 146 which imprison the extensions 29 and 42.

A sa partie inférieure 48, la plaque comporte également des éléments 62 formant harpon élastique venant s'insérer dans le circuit imprimé 70 en traversant d'une part les ouvertures 24' du boîtier 28 de l'élément 2 et les ouvertures 72 du circuit imprimé 70.At its lower part 48, the plate also comprises elements 62 forming an elastic harpoon which is inserted into the printed circuit 70 by crossing on the one hand the openings 24 ′ of the housing 28 of the element 2 and the openings 72 of the printed circuit 70.

Après introduction des harpons 62 dans les ouvertures 72 du circuit imprimé, l'ensemble est verrouillé en position grâce à l'encliquetage des décrochements 73 desdits harpons. En outre, la partie inférieure 48 de la plaque 40 présente un prolongement 49 qui vient en butée contre la face supérieure du circuit imprimé 70 au même niveau que la face inférieure 65 du boîtier 28 de l'élément 2.After introduction of the harpoons 62 into the openings 72 of the printed circuit, the assembly is locked in position by snap-fastening of the recesses 73 of said harpoons. In addition, the lower part 48 of the plate 40 has an extension 49 which abuts against the upper face of the printed circuit 70 at the same level as the lower face 65 of the housing 28 of the element 2.

On remarquera qu'à sa partie arrière, la plaque 40 présente une partie 45 inclinée s'étendant depuis le prolongement 42 jusqu'au harpon arrière 60. Cette partie 45 peut être mise à profit pour y loger, par exemple dans des rainures, un capot s'étendant sur toute la longueur du connecteur.Note that at its rear part, the plate 40 has an inclined part 45 extending from the extension 42 to the rear harpoon 60. This part 45 can be used to accommodate, for example in grooves, a cover extending over the entire length of the connector.

La plaque 40 peut être mise à la masse ce qui permet de réaliser un blindage au moins partiel de l'ensemble de connexion.The plate 40 can be earthed, which allows at least partial shielding of the connection assembly.
