Description

L'invention concerne un ensemble de connexion pour le raccordement de deux cartes de circuits imprimés et notamment le raccordement d'une carte mère et d'une carte fille.The invention relates to a connection assembly for the connection of two printed circuit boards and in particular the connection of a motherboard and a daughter board.

Un ensemble de connexion de ce type est par exemple décrit dans le document FR-A-2.550.894. Il comporte :

  • une fiche solidaire de l'une des deux cartes comportant un bloc isolant dans lequel sont reçus les éléments de contact électriques qui font saillie par leurs extrémités avant hors de la face avant de connexion du bloc isolant et dont les extrémités arrière s'étendent au-delà de la face arrière de raccordement du bloc isolant pour être raccordées à ladite carte ; et
  • une embase solidaire de l'autre des deux cartes comportant un bloc isolant dans lequel sont reçus des éléments de contact électrique prévus pour établir un contact électrique avec les éléments de contact en regard de la fiche par leurs extrémités avant et dont les extrémités arrière s'étendent au-delà de la face arrière de raccordement du bloc isolant pour être raccordées à l'autre carte.
A connection assembly of this type is for example described in the document FR-A-2,550,894. It comprises :
  • a plug secured to one of the two cards comprising an insulating block in which are received the electrical contact elements which project by their front ends out of the front face of connection of the insulating block and whose rear ends extend beyond beyond the rear connection face of the insulating block to be connected to said card; and
  • a base secured to the other of the two cards comprising an insulating block in which are received electrical contact elements provided for establishing electrical contact with the contact elements facing the plug by their front ends and whose rear ends are extend beyond the rear connection side of the insulating block to be connected to the other card.

L'ensemble de connexion décrit dans ce document propose, pour la fiche comme pour l'embase, une structure de connecteur électrique classique dans laquelle la partie formant boîtier et son bloc isolant qui reçoit les contacts électriques sont spécifiques à une seule application, c'est-à-dire à un schéma de raccordement de deux cartes et qui ne peut donc s'adapter aisément à d'autres implantations ou à un nombre différent, ou à une nature différente des éléments de contact électrique. La densité de contacts électriques est particulièrement faible et la force d'insertion nécessaire à la connexion de la fiche dans l'embase est élevée.The connection assembly described in this document proposes, for the plug as for the socket, a conventional electrical connector structure in which the housing part and its insulating block which receives the electrical contacts are specific to a single application, it that is to say a connection diagram of two cards and which cannot therefore easily be adapted to other locations or to a different number, or to a different nature of the electrical contact elements. The density of electrical contacts is particularly low and the insertion force required to connect the plug into the socket is high.

Le but de l'invention est de proposer un nouvel ensemble de connexion qui puisse aisément s'adapter à de nombreuses applications pour le raccordement à très haute densité de contacts électriques sans qu'il soit nécessaire pour cela de modifier complètement la structure et la conception de chacun des connecteurs constituant la fiche et l'embase et permettant donc une grande standardisation de la plupart des composants de l'ensemble de connexion tout en s'adaptant à un perçage de densité et d'écartements constants des différentes cartes que l'on désire raccorder.The object of the invention is to propose a new connection assembly which can easily be adapted to numerous applications for the very high density connection of electrical contacts without it being necessary for this to completely modify the structure and design of each of the connectors constituting the plug and the socket and thus allowing a great standardization of most of the components of the connection assembly while adapting to a drilling of density and constant spacings of the different cards that it is desired to connect.

  • l'embase comporte un cadre périphérique formant corps d'embase dans lequel est reçu au moins un bloc isolant et ses éléments de contact qui forment un module de connexion d'embase, le bloc isolant s'étendant axialement au-delà du bord avant du corps d'embase pour être reçu dans ledit réceptacle.
To this end, the invention provides a set of connections of the type mentioned above, characterized in that:

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 coaxial femelle dont la partie arrière est maintenue et immobilisée dans un alvéole de grandes dimensions 36 du cadre de fiche 14 qui prolonge l'alvéole 34 du bloc 16.In a large cell 34 formed at the top of the insulating block 16, the latter receives a female coaxial contact, the rear part of which is maintained and immobilized in a large cell 36 of the plug frame 14 which extends the cell 34 of block 16.

D'une manière connue le contact coaxial femelle 38 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 coaxial femelle 38.In a known manner, the female coaxial contact 38 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 inwardly which cooperate with a retaining shoulder 42 of the external contact body of the female coaxial contact 38.

La position axiale du module de connexion de fiche constitué par le bloc isolant 16 et par les contacts électriques qui l'équipent est définie par un épaulement interne 44 du corps de fiche contre lequel prend appui un épaulement externe 46 du corps isolant 16 du module de fiche, par une face transversale de l'épaulement tournée vers la face arrière de raccordement 20 du bloc 16.The axial position of the plug connection module constituted by the insulating block 16 and by the electrical contacts which equip it is defined by an internal shoulder 44 of the plug body against which an external shoulder 46 of the insulating body 16 of the module is supported. plug, by a transverse face of the shoulder facing the rear connection face 20 of the block 16.

Le cadre de fiche 14 s'étend axialement vers l'avant par sa paroi latérale d'extrémité avant 48 au-delà de la face avant de connexion 26 du bloc 16 pour délimiter un réceptacle de section rectangulaire prévu pour recevoir une partie de forme complémentaire du bloc isolant de la fiche 11.The plug frame 14 extends axially forwards via its front end side wall 48 beyond the front connection face 26 of the block 16 to delimit a receptacle of rectangular section intended to receive a part of complementary shape of the insulating block of the plug 11.

L'embase 11 comporte d'une manière symétrique un cadre périphérique de section rectangulaire 15 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.The base 11 symmetrically includes a peripheral frame of rectangular section 15 in which is received a base insulating 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.

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 du bloc isolant de fiche 16, les extrémités avant 25 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 male signal 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 on the motherboard 13. The front face of connection 27 of the insulating block of base 17 bears against the front face of connection 26 of the insulating block of plug 16, the front ends 25 of the female electrical contacts penetrating into corresponding cells of the insulating block 27 formed around the ends free before 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 du contact coaxial mâle 39 dans lesquels elle est maintenue axialement vers l'arrière par une virole externe à doigts élastiques 41 qui coopèrent avec un épaulement 43 du corps de contact du contact coaxial 39.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 the male coaxial contact 39 in which it is held axially towards the rear by an external ferrule to elastic fingers 41 which cooperate with a shoulder 43 of the contact body of the coaxial contact 39.

La position axiale du module de connexion d'embase constitué par le bloc isolant 17 et par les contacts qui l'équipent est définie par une cloison transversale 45 du cadre d'embase 15 qui constitue un épaulement axial contre lequel prend appui la face arrière de raccordement 21 du bloc isolant d'embase 17 ou contre un épaulement interne 47 du cadre d'embase 15. Les épaulements et surfaces ainsi en contact sont tournés vers l'arrière pour ce qui concerne le bloc isolant 17 de façon à permettre son introduction axiale dans le cadre d'embase 15 depuis l'avant vers l'arrière.The axial position of the base connection module constituted by the insulating block 17 and by the contacts which equip it is defined by a transverse partition 45 of the base frame 15 which constitutes an axial shoulder against which the rear face of connection 21 of the insulating block of base 17 or against a internal shoulder 47 of the base frame 15. The shoulders and surfaces thus in contact are turned towards the rear as regards the insulating block 17 so as to allow its axial introduction into the base frame 15 from the front towards the back.

Pour permettre le passage des extrémités arrière des éléments de contact de signal mâle 19 en direction de la carte mère 13, la cloison 45 comporte des fentes 49 qui s'étendent perpendiculairement au plan de la carte fille 12 et perpendiculairement à celui de la carte mère 13. Les fentes sont ainsi orientées de façon à permettre, d'une façon qui sera expliquée plus loin, un débattement de l'ensemble de connexion par rapport à la carte mère selon la direction D parallèle au plan de la carte mère.To allow the rear ends of the male signal contact elements 19 to pass towards the motherboard 13, the partition 45 has slots 49 which extend perpendicular to the plane of the daughter card 12 and perpendicular to that of the motherboard 13. The slots are thus oriented so as to allow, in a manner which will be explained below, a clearance of the connection assembly relative to the motherboard in the direction D parallel to the plane of the motherboard.

Le bloc isolant 17 de l'embase 11 s'étend axialement vers l'avant au-delà du bord libre avant 51 du cadre d'embase 15 pour être reçu dans le réceptacle délimité par la paroi avant 48 du cadre de fiche 14.The insulating block 17 of the base 11 extends axially forwards beyond the free front edge 51 of the base frame 15 to be received in the receptacle delimited by the front wall 48 of the plug frame 14.

Cet agencement permet de supprimer le guidage classique entre connecteurs dans lequel un cadre est reçu à l'intérieur d'un autre cadre. On gagne ainsi deux fois l'épaisseur d'une paroi avant de cadre telle que la paroi 48 ce qui permet d'augmenter le nombre de contacts pour un encombrement externe du cadre déterminé. Le guidage lors de l'emboîtement se fait entre le bloc isolant et la paroi avant de cadre. Il est ainsi également rendu possible de réaliser les cadres en matière plastique, comme les blocs isolants, et il n'est plus nécessaire que les deux cadres soient métalliques pour encaisser les efforts lors de l'emboîtement.This arrangement eliminates the conventional guide between connectors in which a frame is received inside another frame. This saves twice the thickness of a front frame wall such as the wall 48, which makes it possible to increase the number of contacts for an external space requirement of the determined frame. Guiding during nesting takes place between the insulating block and the front frame wall. It is thus also made possible to produce the plastic frames, such as the insulating blocks, and it is no longer necessary for the two frames to be metallic in order to withstand the forces during nesting.

Comme le premier contact mutuel entre la fiche et l'embase se fait ici entre le bloc isolant 17 et le cadre de fiche 14 il est nécessaire de prévoir des moyens de détrompage qui seront décrits en référence aux figures 11 à 15.As the first mutual contact between the plug and the socket is made here between the insulating block 17 and the plug frame 14 it is necessary to provide polarization means which will be described with reference to Figures 11 to 15.

Le cadre 14 constituant le corps de la fiche 10 comporte des pattes de fixation 50 sur la carte 12 au moyen de vis 52 telles que représentées à la figure 5.The frame 14 constituting the body of the plug 10 comprises fixing lugs 50 on the card 12 by means of screws 52 as shown in FIG. 5.

Dans le mode de réalisation représenté à la figure 2, on voit que chacun des cadres de fiche et d'embase est prévu pour recevoir trois modules de connexion agencés côte à côte dans trois logements adjacents de chacun des cadres qui sont délimités par des zones 54 et 55 respectivement. C'est dans ces zones 54 et 55 que sont agencés les moyens de fixation des cadres sur leur carte respective, des moyens de détrompage, non représentés et éventuellement des moyens de verrouillage de la fermeture de l'ensemble de connexion.In the embodiment shown in FIG. 2, it can be seen that each of the plug and socket frames is designed to receive three connection modules arranged side by side in three adjacent housings of each of the frames which are delimited by zones 54 and 55 respectively. It is in these zones 54 and 55 that the means for fixing the frames on their respective card are arranged, polarizing means, not shown and possibly means for locking the closure of the connection assembly.

Chaque module de la figure 2 présente 84 alvéoles pour des contacts de signal électrique et quatre alvéoles de plus grandes dimensions qui peuvent recevoir soit un contact coaxial comme à la figure 1, soit un contact de puissance comme à la figure 3, ou encore un élément appelé contact fluidique, non représenté sur les figures, qui permet de faire circuler un liquide caloporteur.Each module in Figure 2 has 84 cells for electrical signal contacts and four larger cells which can receive either a coaxial contact as in Figure 1, or a power contact as in Figure 3, or an element called fluid contact, not shown in the figures, which makes it possible to circulate a heat transfer liquid.

Si l'on veut augmenter encore la densité de raccordement de tels modules il est possible de prévoir par exemple trois alvéoles de contact électrique entre les paires d'alévoles de grandes dimensions 34 et 35, les alvéoles correspondants étant bien entendu aménagés en regard dans les cadres entre les alvéoles 36 et les alvéoles 37.If it is desired to further increase the connection density of such modules, it is possible to provide, for example, three electrical contact cells between the pairs of large cells 34 and 35, the corresponding cells being of course arranged facing each other. frames between the cells 36 and the cells 37.

Il est possible de réaliser des ensembles de connexion de plus petites dimensions utilisant les mêmes modules de connexion en limitant la longueur du cadre à un seul logement, c'est-à-dire par exemple sensiblement le tiers de gauche des cadres 14 et 15 représentés à la figure 2.It is possible to make connection assemblies of smaller dimensions using the same connection modules by limiting the length of the frame to a single housing, that is to say for example substantially the left third of the frames 14 and 15 shown. in Figure 2.

La conception selon l'invention permet d'assembler les éléments de contact de signal et les bandes de masse dans leur module isolant respectif ainsi que les grilles de raccordement, dont les broches sont encore reliées entre elles par des rives, pour former un module de connexion que l'on introduit ensuite dans le cadre correspondant jusqu'à venue en appui axial des épaulements délimitant leur position respective. Les contacts coaxiaux mâle ou femelle se montent par l'arrière dans leurs alvéoles correspondants. La liaison finale entre les blocs isolants 16 et 17 et les cadres 14 et 15 s'effectue en déposant dans la zone des faces arrière 20 et 21 une couche de matériau adhésif appelée "putting" comme cela est indiqué par la lettre P aux figures 4, 5 et 6. En ce qui concerne le bloc isolant d'embase 17, de petits dégagements 51 sont formés qui entourent la partie arrière des contacts électriques 19 et qui peuvent être remplis d'adhésif dans une première étape afin d'immobiliser les contacts par rapport au bloc avant l'introduction du module de connexion dans le cadre.The design according to the invention makes it possible to assemble the signal contact elements and the ground strips in their respective insulating module as well as the connection grids, the pins of which are still connected together by banks, to form a module of connection which is then introduced into the corresponding frame until it comes to axial support of the shoulders delimiting their respective position. The male or female coaxial contacts are mounted from the rear in their corresponding sockets. The final connection between the insulating blocks 16 and 17 and the frames 14 and 15 is carried out by depositing in the area of the rear faces 20 and 21 a layer of adhesive material called "putting" as indicated by the letter P in Figures 4 , 5 and 6. With regard to the insulating block of base 17, small clearances 51 are formed which surround the rear part of the electrical contacts 19 and which can be filled with adhesive in a first step in order to immobilize the contacts relative to the block before the introduction of the connection module in the frame.

Conformément à un aspect de l'invention il est prévu de permettre un débattement selon la direction D de l'ensemble de connexion par rapport à la carte mère 13, notamment lorsque l'ensemble de connexion et la carte fille 12 sont plaqués sur un dispositif d'absorption calorifique pour le refroidissement des circuits appelé "connecteurs guide-carte thermiques". Comme cela a déjà été indiqué les parties arrière des contacts électriques mâle de l'embase 19 sont reçus dans des fentes du cadre d'embase 15 dans lesquelles elles peuvent se déplacer en se déformant légèrement. A cet effet les portions arrière des contacts de signal qui s'étendent à travers les fentes 49 sont avantageusement des portions aplaties d'éléments de contact de sections cylindriques et dont les faces aplaties sont perpendiculaires à la direction de débattement D. Un dégagement 53 est également formé autour de la bande de masse 31 pour en permettre le débattement transversal.In accordance with one aspect of the invention, provision is made to allow movement in the direction D of the connection assembly with respect to the motherboard 13, in particular when the connection assembly and the daughter card 12 are pressed against a device. of heat absorption for cooling circuits called "thermal guide-card connectors". As already indicated, the rear parts of the male electrical contacts of the base 19 are received in slots in the base frame 15 in which they can move with slight deformation. For this purpose, the rear portions of the signal contacts which extend through the slots 49 are advantageously flattened portions of contact elements of sections. cylindrical and whose flattened faces are perpendicular to the direction of travel D. A clearance 53 is also formed around the mass strip 31 to allow transverse movement.

La partie arrière du câble coaxial 55 et du corps externe du contact 39 se débattent dans un orifice de grandes dimensions 57 de la carte 13.The rear part of the coaxial cable 55 and of the external body of the contact 39 struggle in a large opening 57 of the card 13.

Grâce à la combinaison de toutes ces caractéristiques il est donc possible de déplacer légèrement l'ensemble de connexion selon la direction D sans endommager aucun des composants de l'ensemble de connexion, les moyens de fixation entre la fiche et l'embase étant également adaptés à cet effet.Thanks to the combination of all these characteristics, it is therefore possible to slightly move the connection assembly in direction D without damaging any of the components of the connection assembly, the means of attachment between the plug and the socket being also suitable. for this purpose.

Les différents alvéoles, orifices et fentes formés dans les blocs isolants et dans les cadres de fiche et d'embase sont bien entendu agencés en vis à vis les uns des autres, des moyens de détrompage non représentés étant prévus pour le positionnement relatif des blocs dans les cadres.The various cells, orifices and slots formed in the insulating blocks and in the plug and socket frames are of course arranged opposite one another, keying means not shown being provided for the relative positioning of the blocks in executives.

Les alvéoles cylindriques de grandes dimensions 35 à 37 permettent également le montage de contacts de puissance tels que représentés à la figure 3.The large cylindrical cells 35 to 37 also allow the mounting of power contacts as shown in FIG. 3.

Le contact mâle de puissance 60 est monté dans les alvéoles 34 et 36 de la même manière que le contact coaxial mâle 38 de la figure 1. Le raccordement de sa partie arrière non représentée peut être effectué au moyen d'un câble souple ou par une extrémité recourbée permettant son report à plat de la même façon que les broches arrière 22.The male power contact 60 is mounted in the cells 34 and 36 in the same way as the male coaxial contact 38 in FIG. 1. The connection of its rear part, not shown, can be carried out by means of a flexible cable or by a curved end allowing it to be transferred flat in the same way as the rear pins 22.

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

La variante de l'ensemble de connexion représenté à la figure 4 permet le raccordement de deux cartes mère parallèles 12 et 13, les extrémités arrière des contacts électriques de signal ou des contacts coaxiaux et des contacts de puissance étant symétriques, les autres composants de la fiche 10 et de l'embase 11 étant similaires à ceux du mode de réalisation représenté aux figures précédentes.The variant of the connection assembly shown in Figure 4 allows the connection of two motherboards parallel 12 and 13, the rear ends of the electrical signal contacts or of the coaxial contacts and of the power contacts being symmetrical, the other components of the plug 10 and of the socket 11 being similar to those of the embodiment shown in the preceding figures .

L'ensemble de connexion représenté à la figure 5 diffère de celui de la figure 1 d'une part en ce qu'il ne comporte pas de bandes de connexion de masse, et d'autre part en ce que les grilles de raccordement 22 des extrémités arrière des contacts femelle 18 de la fiche 10 sont reliées à la carte 12 par piquage dans cette carte. Une bande de masse pourrait néanmoins être prévue et surmoulée comme dans les exemples précédents.The connection assembly shown in FIG. 5 differs from that of FIG. 1 on the one hand in that it does not include ground connection strips, and on the other hand in that the connection grids 22 of the rear ends of the female contacts 18 of the plug 10 are connected to the card 12 by stitching into this card. A ground band could nevertheless be provided and overmolded as in the previous examples.

Comme il n'y a pas de bande de masse, un bouchon 64 peut être moulé dans le bloc isolant 14 pour fermer la fente 28 vers l'arrière.Since there is no ground strip, a plug 64 can be molded in the insulating block 14 to close the slot 28 towards the rear.

Dans le module de connexion représenté à la figure 6, l'embase 11 est modifiée dans sa partie arrière pour permettre le raccordement d'une carte fille 12 sur une carte fille prolongatrice 13 dans le prolongement l'une de l'autre c'est-à-dire pour constituer un ensemble appelé prolongateur.In the connection module shown in FIG. 6, the base 11 is modified in its rear part to allow the connection of a daughter card 12 to an extension daughter card 13 in line with one another. that is to say to constitute a set called extension.

La partie arrière de l'embase de prolongateur 11 est ainsi symétrique à celle de la fiche représentée notamment aux figures 1 et 2 et comporte des pattes de fixation 100 sur la deuxième carte mère 13. Une embase formant prolongateur est représentée aux figures 9 et 10.The rear part of the extension base 11 is thus symmetrical to that of the plug shown in particular in FIGS. 1 and 2 and includes fixing lugs 100 on the second motherboard 13. A base forming an extension is shown in FIGS. 9 and 10 .

Dans les descriptions qui précèdent l'ensemble des contacts de signal de la fiche 10 sont des contacts femelle tandis que les éléments de contact de l'embase 11 sont des contacts mâle. On constate qu'en combinant une embase de prolongateur 11 telle que représentée à la figure 6 avec une fiche permettant le piquage telle que représentée à la figure 4, il est possible d'inverser le sens de connexion c'est-à-dire d'équiper la carte mère avec des contacts femelle et la carte fille avec des contacts mâle.In the foregoing descriptions, all of the signal contacts of the plug 10 are female contacts while the contact elements of the base 11 are male contacts. It can be seen that by combining an extension base 11 as shown in FIG. 6 with a plug allowing the stitching such that shown in Figure 4, it is possible to reverse the direction of connection, that is to say, to equip the motherboard with female contacts and the daughter board with male contacts.

On a ainsi réalisé une gamme complète d'ensembles de connexion permettant de réaliser toutes les variantes possibles de liaisons de cartes à circuits imprimés.A complete range of connection assemblies has thus been produced, making it possible to produce all the possible variants of connections of printed circuit boards.

On a représenté aux figures 11 à 13 une extrémité latérale d'un cadre d'embase 15 qui reçoit un module de connexion d'embase 17 représenté aux figures 14 et 15.FIGS. 11 to 13 show a lateral end of a base frame 15 which receives a base connection module 17 shown in FIGS. 14 and 15.

La zone d'extrémité 55 se présente sous forme d'un pavé rectangulaire dont une face latérale 201 tournée vers le logement du bloc isolant 17 est munie d'un doigt de détrompage 203. Le doigt s'étend depuis la face avant de la cloison 45 le long du pavé 55 et fait saillie axialement au-delà de la face libre de ce dernier.The end zone 55 is in the form of a rectangular block, a side face 201 facing the housing of the insulating block 17 is provided with a coding finger 203. The finger extends from the front face of the partition 45 along the block 55 and projects axially beyond the free face of the latter.

La face latérale 205 du bloc isolant 17 qui est tournée vers la face 201 comporte une rainure axiale 207 qui reçoit le doigt 203 et le rigidifie.The lateral face 205 of the insulating block 17 which faces the face 201 has an axial groove 207 which receives the finger 203 and stiffens it.

Le doigt 203 s'étend axialement au-delà de la face avant 27 du bloc isolant 17 en direction de la fiche pour être reçu dans un trou de détrompage de section correspondante formé dans la paroi latérale du cadre de fiche correspondant (non représenté).The finger 203 extends axially beyond the front face 27 of the insulating block 17 in the direction of the plug to be received in a keying hole of corresponding section formed in the side wall of the corresponding plug frame (not shown).

Un doigt de détrompage identique est aménagé symétriquement à l'autre extrémité du cadre d'embase 15 ainsi qu'un trou correspondant dans le cadre de fiche.An identical coding finger is arranged symmetrically at the other end of the base frame 15 as well as a corresponding hole in the plug frame.

Les doigts et trous sont bien entendu décalés par rapport au plan médian des cadres pour assurer la fonction de détrompage. Il n'est pas nécessaire de prévoir de rainure latérale dans le bloc isolant 16 de la fiche car sa face avant 26 est en retrait de l'extrémité libre 209 du doigt 203.The fingers and holes are of course offset relative to the median plane of the frames to ensure the polarization function. It is not necessary to provide a lateral groove in the insulating block 16 of the plug because its front face 26 is set back from the free end 209 of the finger 203.
