Description

La présente invention concerne un élément de connecteur électrique du type comportant un bloc isolant dans lequel est formé au moins partiellement au moins un alvéole traversant qui reçoit un élément de contact électrique.The present invention relates to an electrical connector element of the type comprising an insulating block in which is formed at least partially at least one through cell which receives an electrical contact element.

Il est connu de maintenir l'élément de contact électrique dans l'alvéole et de l'y immobiliser axialement en direction d'une des faces, et notamment de la face arrière, du bloc isolant au moyen d'une virole de retenue comportant des doigts déformés élastiquement radialement vers l'intérieur qui coopèrent avec un épaulement de retenue du corps de contact de l'élément de contact électrique.It is known to hold the electrical contact element in the cell and immobilize it there axially in the direction of one of the faces, and in particular of the rear face, of the insulating block by means of a retaining ring comprising elastically deformed fingers radially inwardly which cooperate with a shoulder for retaining the contact body of the electrical contact element.

L'invention a pour but de proposer une conception d'élément de connecteur électrique qui permet le montage de contacts par une face du bloc isolant et son démontage au moins partiel, notamment pour en permettre une réparation, par l'autre face du bloc isolant.The object of the invention is to propose an electrical connector element design which allows the mounting of contacts by one side of the insulating block and its at least partial disassembly, in particular to allow repair thereof, by the other side of the insulating block. .

Dans ce but l'invention propose un élément de connecteur électrique caractérisé en ce que l'élément de contact électrique comporte un corps central de contact reçu dans une douille intermédiaire elle-même reçue dans l'alvéole du bloc isolant par rapport auquel elle est immobilisée axialement dans une première direction par coopération de deux épaulements formés en vis-à-vis respectivement sur la douille et dans l'alvéole, et dans une seconde direction par coopération de deux autres épaulements en vis-à-vis entre lesquels est interposée une virole externe de maintien effaçable depuis l'une des faces d'extrémité du bloc isolant, le corps de contact étant immobilisé axialement par rapport à la douille dans une seconde direction opposée par coopération de deux épaulements formés en vis-à-vis respectivement sur le corps de contact et dans la douille, et dans ladite première direction par coopération de deux autres épaulements en vis-à-vis entre lesquels est interposée une virole interne de maintien effaçable depuis l'autre face d'extrémité du bloc isolant.For this purpose the invention provides an electrical connector element characterized in that the electrical contact element comprises a central contact body received in an intermediate socket itself received in the cell of the insulating block with respect to which it is immobilized axially in a first direction by cooperation of two shoulders formed vis-à-vis respectively on the sleeve and in the cell, and in a second direction by cooperation of two other shoulders vis-à-vis between which a ferrule is interposed external support erasable from one of the end faces of the insulating block, the contact body being immobilized axially with respect to the sleeve in a second opposite direction by cooperation of two shoulders formed opposite each other respectively on the body contact and in the socket, and in said first direction by cooperation of two others facing shoulders between which is interposed an internal shroud erasable from the other end face of the insulating block.

Selon une autre caractéristique de l'invention, les viroles externe et interne comportent chacune des doigts déformés élastiquement radialement vers l'intérieur qui coopèrent respectivement par leurs extrémités libres avec un épaulement radial externe de la douille et un épaulement radial externe du corps de contact.According to another characteristic of the invention, the external and internal ferrules each have elastically radially inwardly deformed fingers which cooperate respectively by their free ends with an external radial shoulder of the sleeve and an external radial shoulder of the contact body.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui va suivre pour la compréhension de laquelle on se reportera au dessin annexé dont la figure unique est une vue en coupe axiale par un plan perpendiculaire à des cartes mère et fille d'un ensemble de connexion, le plan de coupe passant par des éléments de contact de signal et par un élément de contact électrique de puissance monté dans un élément de connecteur conforme aux enseignements de l'invention.Other characteristics and advantages of the invention will appear on reading the detailed description which follows, for the understanding of which reference will be made to the appended drawing, the single figure of which is a view in axial section through a plane perpendicular to motherboards. and daughter of a connection assembly, the cutting plane passing through signal contact elements and through an electrical power contact element mounted in a connector element in accordance with the teachings of the invention.

On a représenté à la figure un ensemble de connexion de deux cartes de circuits imprimés mère et fille du type de celui décrit et représenté dans la demande de brevet français n° 89 07264 au contenu de laquelle on pourra se reporter pour en connaître la structure et les détails de conception.There is shown in the figure a connection assembly of two mother and daughter printed circuit boards of the type described and shown in French patent application n ° 89 07264, the content of which may be referred to for the structure thereof and design details.

L'ensemble de connexion comporte deux éléments de connecteur, une fiche 10 et une embase 11 pour le raccordement électrique de pistes électriques formées respectivement sur une carte fille 12 et une carte mère 13. La fiche 10 comporte un cadre périphérique creux de section rectangulaire 14 dans lequel est reçu un bloc en matériau isolant 16.The connection assembly comprises two connector elements, a plug 10 and a base 11 for the electrical connection of electrical tracks formed respectively on a daughter board 12 and a motherboard 13. The plug 10 comprises a hollow peripheral frame of rectangular section 14 in which a block of insulating material 16 is received.

Dans sa partie inférieure représentée à la figure 1, le bloc isolant 16 reçoit dans des alvéoles de petites dimensions des éléments de contact électrique femelle 18 permettant par exemple la transmission d'un signal électrique. Les éléments de contact électrique 18 font saillie axialement au-delà de la face arrière 20 du bloc isolant de fiche 16 pour être raccordés à l'une des faces de la carte mère 12 au moyen de grilles de raccordement 22.In its lower part shown in FIG. 1, the insulating block 16 receives electrical contact elements in small cells. female 18 allowing for example the transmission of an electrical signal. The electrical contact elements 18 protrude axially beyond the rear face 20 of the plug insulating block 16 so as to be connected to one of the faces of the motherboard 12 by means of connection grids 22.

Les extrémités avant 24 des contacts 18 font saillie axialement au-delà de la face avant 26 du bloc isolant 16 en direction de l'embase 11.The front ends 24 of the contacts 18 project axially beyond the front face 26 of the insulating block 16 in the direction of the base 11.

Au-dessus des trois contacts 18, le bloc isolant 16 comporte dans sa partie médiane une fente débouchante 28 qui reçoit une bande de connexion de masse 30 dont l'extrémité avant 32 fait saillie axialement en direction de l'embase 11 au-delà de la face avant 26 du bloc 16.Above the three contacts 18, the insulating block 16 has in its middle part a through slot 28 which receives a ground connection strip 30, the front end 32 of which projects axially in the direction of the base 11 beyond the front face 26 of the block 16.

Dans un alvéole de grandes dimensions 34 formé à la partie supérieure du bloc isolant 16, ce dernier reçoit un contact de puissance mâle 60 dont la partie arrière est maintenue et immobilisée axialement dans un alvéole de grandes dimensions 36 du cadre de fiche 14 qui prolonge l'alvéole 34 du bloc isolant 16.In a large cell 34 formed at the top of the insulating block 16, the latter receives a male power contact 60, the rear part of which is held and immobilized axially in a large cell 36 of the plug frame 14 which extends the cell 34 of the insulating block 16.

D'une manière connue selon l'état de la technique, le contact de puissance 60 est monté par l'arrière dans la fiche 10 et y est immobilisé axialement en direction de l'arrière par une virole de retenue 40 comportant des doigts déformés élastiquement radialement vers l'intérieur qui coopèrent avec un épaulement de retenue 42 du corps de contact externe du contact 60.In a known manner according to the state of the art, the power contact 60 is mounted from the rear in the plug 10 and is immobilized there axially in the direction of the rear by a retaining ring 40 comprising elastically deformed fingers radially inwards which cooperate with a retaining shoulder 42 of the external contact body of the contact 60.

L'embase 11 comporte d'une manière symétrique un cadre périphérique 15 de section rectangulaire dans lequel est reçu un bloc isolant d'embase 17. Des alvéoles de petites dimensions reçoivent trois éléments de contact électrique mâle 19 prévus pour coopérer électriquement par leurs extrémités avant 25 avec les extrémités avant 24 des contacts femelles 18. Les contacts électriques mâles de signal 19 s'étendent axialement vers l'arrière de l'embase 11 au-delà de la face arrière de raccordement 21 du bloc isolant 17 pour pénétrer dans des trous de piquage correspondants 23 de la carte mère 13. La face avant de connexion 27 du bloc isolant d'embase 17 est en appui contre la face avant de connexion 26 de bloc isolant de fiche 16, les extrémités avant 24 des contacts électriques femelles pénétrant dans des alvéoles correspondants du bloc isolant 27 formés autour des extrémités libres avant 25 des contacts électriques mâles 19.The base 11 symmetrically comprises a peripheral frame 15 of rectangular section in which is received an insulating base block 17. Small cells receive three male electrical contact elements 19 provided for cooperating electrically by their front ends 25 with the front ends 24 of the female contacts 18. The signal male electrical contacts 19 extend axially towards the rear of the base 11 beyond the rear connection face 21 of the insulating block 17 to penetrate corresponding tap holes 23 of the motherboard 13. The face front of connection 27 of the insulating block of base 17 is in abutment against the front of connection 26 of insulating block of plug 16, the front ends 24 of the female electrical contacts penetrating into corresponding cells of the insulating block 27 formed around the free ends front 25 of the male electrical contacts 19.

Le bloc isolant d'embase 17 comporte une fente 29 dans laquelle est reçue une bande de connexion de masse 31 dont l'extrémité avant en forme de pince 33 reçoit l'extrémité avant 32 de la bande de masse 30 de la fiche 10.The insulating base block 17 has a slot 29 in which a ground connection strip 31 is received, the front end of which in the form of a clamp 33 receives the front end 32 of the ground strip 30 of the plug 10.

A sa partie supérieure, le bloc isolant 17 et le cadre d'embase 15 comportent des alvéoles de grandes dimensions 35 et 37 qui reçoivent la partie arrière d'un contact femelle de puissance 61 complémentaire du contact mâle 60.At its upper part, the insulating block 17 and the base frame 15 have large cells 35 and 37 which receive the rear part of a female power contact 61 complementary to the male contact 60.

Le contact femelle 61 présente une structure originale permettant son montage par l'arrière et son démontage partiel pour une réparation par l'avant ainsi qu'un débattement transversal selon la direction D.The female contact 61 has an original structure allowing it to be mounted from the rear and its partial disassembly for repair from the front as well as a transverse movement in the direction D.

Le corps de contact femelle 63 se prolonge vers l'arrière par un manchon cylindrique interne épaulé 65 qui est disposé dans une douille intermédiaire épaulée 67 qui est elle-même reçue dans les alvéoles 35 et 37.The female contact body 63 is extended towards the rear by an internal shouldered cylindrical sleeve 65 which is disposed in an intermediate shouldered socket 67 which is itself received in the cells 35 and 37.

Le positionnement axial et le maintien de la douille intermédiaire 67 dans les alvéoles est classique et identique à celui du corps de contact mâle 60, c'est-à-dire au moyen d'une virole à doigts élastiques internes 41 dont les extrémités coopèrent avec un épaulement 69 lui-même en appui contre un épaulement en vis-à-vis 71 du bloc isolant.The axial positioning and holding of the intermediate socket 67 in the cells is conventional and identical to that of the male contact body 60, that is to say by means of a ferrule with internal elastic fingers 41 whose ends cooperate with a shoulder 69 itself in abutment against a shoulder in vis-à-vis 71 of the insulating block.

De manière originale le manchon cylindrique interne est positionné et maintenu dans la douille intermédiaire 67 au moyen d'une virole interne de maintien 73 de structure similaire à celle de la virole externe 41. L'agencement de la virole interne est inversé axialement de manière que les extrémités libres des doigts déformés radialement vers l'intérieur soient en appui contre une face en vis-à-vis 75 de l'épaulement arrière du manchon interne 65.In an original manner, the internal cylindrical sleeve is positioned and held in the intermediate sleeve 67 by means of an internal retaining ferrule 73 of structure similar to that of the external ferrule 41. The arrangement of the internal ferrule is axially reversed so that the free ends of the fingers deformed radially inwards are in abutment against a face opposite 75 of the rear shoulder of the internal sleeve 65.

Une bague annulaire fendue 77 est montée entre le manchon interne étagé 65 et la virole interne 73 de façon à pouvoir être poussée axialement vers l'arrière par l'intermédiaire de son extrémité en saillie 79 afin de permettre un démontage par l'avant du corps de contact 61 et du manchon 65.A split annular ring 77 is mounted between the stepped inner sleeve 65 and the inner ferrule 73 so that it can be pushed axially towards the rear via its projecting end 79 in order to allow disassembly from the front of the body contact 61 and sleeve 65.

L'extrémité 79 peut être omise et remplacée par un outil, non représenté, que l'on fait pénétrer à l'intérieur du contact femelle de puissance par les fentes 81 prévues pour la ou les extrémités 79, la bague 77 étant une bague fendue montée à demeure dans le contact.The end 79 can be omitted and replaced by a tool, not shown, which is made to penetrate inside the female power contact by the slots 81 provided for the end (s) 79, the ring 77 being a split ring permanently mounted in the contact.

Le premier montage du contact femelle de puissance se fait en introduisant par l'arrière dans les alvéoles 35 et 37 l'ensemble constitué par la douille intermédiaire 67 et par le corps de contact 61 proprement dit, celui-ci ayant déjà été préalablement positionné dans la douille intermédiaire 67. Un conducteur en cuivre à haute conductibilité 85 a été introduit à l'intérieur du manchon étagé 65 jusqu'à ce que son extrémité libre 87 puisse être brasée par l'avant dans le corps de contact 61 avant le montage dans les alvéoles.The first assembly of the female power contact is done by introducing from the rear into the cells 35 and 37 the assembly constituted by the intermediate socket 67 and by the contact body 61 itself, the latter having already been positioned in the intermediate sleeve 67. A high conductivity copper conductor 85 has been introduced inside the stepped sleeve 65 until its free end 87 can be brazed from the front into the contact body 61 before mounting in the alveoli.

Si l'on veut effectuer une réparation il est possible d'extraire par l'avant la partie interne du contact femelle c'est-à-dire l'élément 61-65 en agissant sur la virole interne de maintien 73, la douille intermédiaire 67 restant en place dans l'embase 11, tout ceci après avoir déssoudé le conducteur 85.If you want to carry out a repair, it is possible to extract the internal part of the female contact from the front, i.e. element 61-65 by acting on the internal retaining ring 73, the intermediate socket 67 remaining in place in the base 11, all this after having unsoldered the conductor 85.

Un débattement axial D est rendu possible grâce à la faible section du conducteur 85 qui est reçu avec un jeu radial dans un alésage interne 91 du manchon 65.An axial clearance D is made possible by the small cross section of the conductor 85 which is received with a radial clearance in an internal bore 91 of the sleeve 65.

Selon une variante non représentée, et dans le cas où il n'est pas nécessaire de prévoir une possibilité de débattement transversal D, le manchon interne 65 et le conducteur 85 forment un seul élément de diamètre plus important sans jeu radial de débattement.According to a variant not shown, and in the case where it is not necessary to provide a possibility of transverse movement D, the internal sleeve 65 and the conductor 85 form a single element of larger diameter without radial clearance.

On remarque que le contact de puissance femelle représenté à la figure conserve la fonction classique de réparation par extraction par l'arrière en agissant sur la virole 41 qui permet d'extraire l'ensemble du contact y compris la douille intermédiaire 67 au moyen d'un outil classique en forme de bague introduit dans le jeu radial prévu à cet effet.It is noted that the female power contact shown in the figure retains the conventional repair function by extraction from the rear by acting on the ferrule 41 which makes it possible to extract the entire contact including the intermediate socket 67 by means of a conventional ring-shaped tool introduced into the radial clearance provided for this purpose.

La combinaison originale de deux viroles effaçables externe et interne permet ainsi le montage par l'arrière du contact de puissance et sa séparation au moins partielle par extraction par l'avant sans avoir à démonter l'ensemble de l'embase 11 de la carte 13.The original combination of two external and internal erasable ferrules thus allows the rear mounting of the power contact and its at least partial separation by extraction from the front without having to dismantle the entire base 11 of the card 13 .

L'invention qui vient d'être décrite n'est bien entendu pas limitée à son application à un ensemble de connexion pour raccorder des cartes à circuits imprimés mère et fille mais trouve à s'appliquer à tous les types d'ensembles de connexion connus et dont les applications peuvent nécessiter un montage selon une première direction et un démontage au moins partiel selon une seconde direction opposée.The invention which has just been described is of course not limited to its application to a connection assembly for connecting mother and daughter printed circuit boards but is applicable to all types of known connection assemblies and whose applications may require mounting in a first direction and at least partial disassembly in a second opposite direction.
