Selon un mode de réalisation préféré, les éléments du couple de contacts de masse, sont disposés de manière telle que, lorsque la fiche et l'embase sont assemblées pour coopérer électriquement, le premier et le deuxième éléments du couple de contacts de masse assurent une continuité électrique de masse alors que subsiste encore un jeu minimal a (non nul) entre les premiers éléments de contact de signal de la fiche et de l'embase. Ceci permet d'assurer que la continuité de contact de masse soit établie avant que les éléments de contact de signaux ne soient interconnectés, et a fortiori, avant l'interconnexion des éléments de contact d'alimentation situés à l'opposé.According to a preferred embodiment, the elements of the pair of ground contacts are arranged in such a way that, when the plug and the base are assembled to cooperate electrically, the first and the second elements of the pair of ground contacts provide a electrical ground continuity while there is still a minimum clearance a (not zero) between the first signal contact elements of the plug and the socket.

Selon une variante particulièrement avantageuse du mode de réalisation préféré, la première et la deuxième portions d'accouplement d'une part, et les éléments du couple de contacts de masse, d'autre part, sont disposés de manière telle que le jeu minimal a est obtenu dans une position où la première portion d'accouplement est en contact avec la deuxième portion d'accouplement, à une extrémité opposée aux parties intermédiaires, respectivement de la fiche et de l'embase et où des axes longitudinaux de la fiche et de l'embase forment entre eux un angle α non nul.According to a particularly advantageous variant of the preferred embodiment, the first and second coupling portions on the one hand, and the elements of the mass of ground contacts, on the other hand, are arranged in such a way that the minimum clearance has is obtained in a position where the first coupling portion is in contact with the second coupling portion, at an end opposite to the intermediate parts, respectively of the plug and of the socket and where the longitudinal axes of the plug and of the base form between them a non-zero angle α.
Selon un mode de réalisation de l'invention particulièrement avantageux, la fiche et l'embase constituant un ensemble de connexion selon l'invention ne peuvent être montées qu'entre elles et par conséquent, ne peuvent être connectées à des éléments de type voisin ne comportant pas de connexion de masse.According to a particularly advantageous embodiment of the invention, the plug and the socket constituting a connection assembly according to the invention can only be mounted together and therefore cannot be connected to elements of the neighboring type. with no ground connection.
Selon un premier mode de réalisation, le deuxième élément de contact de masse de l'embase est une douille dont la forme est telle que ledit doigt de polarisation de la fiche standard selon la norme "ARINC 600" vienne buter sur ladite douille de l'embase selon l'invention.According to a first embodiment, the second mass contact element of the base is a socket whose shape is such that said polarization finger of the standard plug according to the "ARINC 600" standard comes to abut on said socket of the base according to the invention.
Selon une autre variante, la fiche comporte un doigt cylindrique coaxial à un doigt de polarisation de la fiche standard par exemple selon la norme "ARINC 600" de telle sorte que le doigt cylindrique vienne buter sur un oeil de polarisation d'une embase standard par exemple selon la norme "ARINC 600" sans qu'une broche de masse portée par ladite fiche vienne elle-même en butée sur ladite embase standard.According to another variant, the plug comprises a cylindrical finger coaxial with a polarization finger of the standard plug, for example according to the "ARINC 600" standard so that the cylindrical finger comes to abut on a polarization eye of a standard base for example according to the "ARINC 600" standard without a ground pin carried by said plug itself coming into abutment on said standard base.
La fiche peut présenter au moins une broche de masse, un doigt de polarisation standard et un doigt cylindrique et l'embase peut comporter alors une douille de masse disposée de manière à coopérer mécaniquement avec la broche de masse, un oeil de polarisation standard disposé de manière à coopérer mécaniquement avec ledit doigt de polarisation, et une ouverture cylindrique disposée de manière à coopérer mécaniquement avec ledit doigt cylindrique.The plug may have at least one ground pin, a standard polarization finger and a cylindrical finger and the base may then comprise a ground socket arranged so as to mechanically cooperate with the ground pin, a standard polarization eye arranged so as to mechanically cooperate with said polarizing finger, and a cylindrical opening arranged so as to mechanically cooperate with said cylindrical finger.

Selon la figure 1, une embase désignée par le repère général 1 est destinée à recevoir une fiche désignée par le repère général 2. L'embase 1 comporte une première région comportant deux secteurs d'accouplement 3 et 3' recevant chacune des éléments de contact mâles ou femelles 10 logés dans des corps isolants, respectivement 17 et 18. L'embase présente également une deuxième région comportant des contacts d'alimentation électrique 41 et 45 logés dans un corps isolant, respectivement en 42 et en 47 et dont les parties arrière, respectivement 43 et 46 entourées d'isolant 48 sont destinés à recevoir des câbles d'alimentation. Ces contacts d'alimentation sont logés dans une deuxième région d'accouplement 4. De même, la fiche 2 comporte des secteurs d'accouplement 6 et 6' correspondant respectivement aux régions d'accouplement 3 et 3' de l'embase 1 et qui comportent des éléments de contact électrique 20 de type opposé aux éléments de contact 10 et qui sont logés dans des corps isolants, respectivement 27 et 28. La fiche présente également une deuxième partie comportant des contacts d'alimentation électrique 71 et 75 logés dans un corps isolant, respectivement en 72 et 77, et dont les parties arrière 73 et 76 sont destinées à recevoir des câbles d'alimentation de puissance. La première partie de l'embase 1 est délimitée par un contour 11 de forme sensiblement rectangulaire présentant en coupe longitudinale la forme d'un U allongé et qui entoure les contacts 10 et qui coopère avec un contour correspondant 21 du corps de fiche 2. Les contours 11 et 21 forment ainsi deux portions d'accouplement mécanique complémentaires. Le contour 11 et 21 participent en général d'un blindage électromagnétique. Tel que représenté, le contour 21 est du type mâle et le contour 11 est du type femelle. Il en va de même autour de la deuxième région d'alimentation électrique pour lequel l'embase 1 comporte un contour 56 de section sensiblement carrée pour entourer les contacts d'alimentation électrique 41 et 45 et qui coopèrent avec un contour 87 également de section sensiblement carrée de la fiche 2 et référencé 87. Les contours 56 et 87 forment ainsi deux portions d'accouplement mécanique complémentaires qui peuvent également participer d'un blindage électromagnétique. Tel que représenté, le contour 87 est du type mâle et le contour 56, du type femelle. L'embase 1 comporte entre le secteur d'accouplement 3' des contacts 10 et le secteur d'accouplement 4 des contacts d'alimentation électrique, une région intermédiaire 8 qui est destinée, dans les connecteurs standards selon la norme "ARINC 600" à réaliser des fonctions de détrompage. Cette fonction de détrompage, qui est ici de préférence conservée, est réalisée par un doigt de polarisation standard 84 disposé dans la fiche 2 et coopérant avec un oeil de polarisation standard 55 disposé en vis-à-vis dans l'embase 1. Les contours 11 et 56 de l'embase font partie d'un même corps d'embase métallique dans lequel sont logés d'une part les corps isolants 17 et 18 séparés par une aile 16, les éléments de contact d'alimentation électrique étant logés dans des ouvertures pratiquées dans une région 49, l'oeil de polarisation standard 55 étant ménagée dans une région 59. Il en va de même pour la fiche 2 pour laquelle les corps isolants 27 et 28 sont logés dans un corps de fiche et sont séparés par une aile 26, alors que des contacts d'alimentation électrique sont logés dans une région 79, le doigt de polarisation standard 84 étant logé, par exemple serti, en 86 dans une région 89 du corps de fiche.According to FIG. 1, a base designated by the
Selon l'invention, la région 59 comporte également une douille 51 de contact de masse sertie en 53 dans la région 59 et dont la partie arrière 52 est destinée à recevoir un fil de contact de masse référencé 92 à la figure 2, alors que la fiche 2 comporte, dans la région 89, une broche de contact de masse 81 sertie en 83 et dont la partie arrière 82 est destinée à être connectée à un fil de contact de masse référencé 93 à la figure 2.According to the invention,
Comme représentés à la figure 1, les bords extrêmes des contours 11 et 21 sont représentés en contact l'un sur l'autre respectivement en 15 et 25, alors que la douille 51 et la broche 81 de contact de masse rentrent juste en contact électrique. Dans cette position, les longueurs des broches 81 et de la douille 51 sont telles qu'un jeu au moins égal à a subsiste entre les contacts 10 et 20 les plus proches, alors que les éléments 51 et 81 assurent déjà une continuité électrique de masse ; ce qui fait qu'il est assuré qu'en toute circonstance, le contact de masse est établi (ou supprimé) alors que les éléments 10 et 20 ne sont pas (ou plus) en contact électrique. Cette caractéristique permet d'éviter des incidents électriques lors de la connexion ou de la déconnexion de la fiche 2 et de l'embase 1.As shown in FIG. 1, the extreme edges of the
Le jeu a a de préférence une valeur au moins égale à 1,5 mm qui correspond à une norme d'isolement dans l'air. En d'autres termes, la connexion de masse doit, dans ce cas, être certaine avant que la distance entre les contacts 10 et 20 les plus proches soit inférieure à 1,5 mm. Même dans le cas où un blindage électromagnétique est mis en oeuvre, des différences de potentiels peuvent apparaître entre les contacts de signal de la fiche et de l'embase, qui soient suffisamment importantes pour déteriorer des circuits couplés aux contacts de signal. Ces différences de potentiel peuvent être suffisamment élevées pour produire un arc électrique entre deux contacts de signal 10 et 20. Ceci est donc évité en assurant la continuité électrique de masse avant rapprochement des contacts 10 et 20.The clearance a preferably has a value at least equal to 1.5 mm which corresponds to a standard of insulation in air. In other words, the ground connection must, in this case, be certain before the distance between the
La figure 2 représente un ensemble fiche 2 et embase 1 en position de connexion permettant ainsi une continuité de la masse entre les câbles 92 et 93 ainsi qu'un détrompage (doigt 84).FIG. 2 represents a set of
Les figures 3a et 3b représentent plus particulièrement une embase 1 et une fiche 2 permettant d'obtenir une fonction de détrompage d'une part entre elles et d'autre part avec des fiches et des embases de standard "ARINC 600" mais ne présentant pas de contact de masse. Pour ce faire, l'embase 1 présente une douille de contact de masse 51, un oeil de polarisation standard 55, et une ouverture circulaire 91, ces trois éléments étant disposés selon un triangle. De la même façon, la fiche 2 comporte une broche de masse 81 destinée à coopérer avec la douille 51, un doigt de polarisation standard 84 destiné à coopérer avec l'oeil de polarisation 55 de l'embase 1 et enfin, un doigt cylindrique 90 dont le diamètre correspond à celui de l'ouverture 91 de l'embase 1. Ces éléments permettent de réaliser une fonction de détrompage à la fois entre une fiche selon l'invention et une embase standard ainsi qu'entre une embase selon l'invention et une fiche standard.Figures 3a and 3b show more particularly a
Comme le montrent les figures 4a et 4b, ces deux fonctions peuvent être obtenues en combinaison ou séparément.As shown in Figures 4a and 4b, these two functions can be obtained in combination or separately.
Selon la figure 4a, un détrompage est obtenu entre une embase selon l'invention et une fiche standard par le fait que, si on essaye d'accoupler une embase 1 et une fiche standard 200, le doigt de polarisation hermaphrodite 201 vient en butée avec le bord externe de la douille 51 d'où une impossibilité de montage.According to FIG. 4a, a polarization is obtained between a base according to the invention and a plug standard by the fact that, if an attempt is made to couple a
Selon la figure 4b, la connexion est rendue impossible entre une fiche 2 selon l'invention et une embase standard 100 par le fait que le doigt de polarisation cylindrique 90 de la fiche 2 ne peut pénétrer dans l'oeil de polarisation 155 qui lui fait face dans l'embase standard 100. En particulier, étant donné que le doigt de polarisation cylindrique est plus long que la broche 81, celle-ci ne vient pas en butée contre l'embase standard 100 et ne peut donc être endommagée lors de l'opération.According to FIG. 4b, the connection is made impossible between a
Selon les figures 5a et 5b, l'embase 1 comporte deux douilles de masse 51 et un oeil de polarisation 155', alors que la fiche 2 comporte deux broches de masse 81 disposées en face des douilles 51 et un doigt de polarisation 90' disposé en face de l'oeil de polarisation 155' et présentant un profil de détrompage (ici en forme de T) complémentaire de ce dernier de manière à permettre leur accouplement. Comme dans les cas précédents, l'embase 1 ne peut être montée sur une fiche standard et la fiche 2 ne peut être montée sur une embase standard.According to Figures 5a and 5b, the
