Description
La présente invention vise une fiche de connexions électriques. The present invention relates to a plug of electrical connections.
La présente invention se rapporte à une fiche plus particulièrement destinée a l'alimentation des machines calculatrices tels que des ordi-nateurs. The present invention relates to a plug more particularly intended for the supply of calculating machines such as computers.
La technique antérieure connait des fiches qui comprennent un élément isolant supportant une série d'organes de contact mâles ou femelles, reliés chacun à un conducteur electrique, ceux-ci étant logés dans une gaine blindée et l'élément isolant étant supporté par un boîtier destiné à être monté sur une prise correspondante. The prior art knows plugs which include an insulating element supporting a series of male or female contact members, each connected to an electrical conductor, these being housed in a shielded sheath and the insulating element being supported by a housing intended to be mounted on a corresponding socket.
Dans cette technique, l'élément isolant qui supporte les organes de contact mâles ou femelles est en partie logé dans un organe de blindage qui est maintenu dans le boitier, toutefois cet organe de blindage s'étend à l'exterieur du boîtier du côté de celui--ci destiné à être enfiché. In this technique, the insulating element which supports the male or female contact members is partly housed in a shielding member which is held in the housing, however this shielding member extends outside the housing on the side of this intended to be plugged in.
On a constaté que de telles fiches présentaient l'inconve- nient de ne pas éviter les inter-actions parasites.It has been found that such files have the disadvantage of not avoiding parasitic interactions.
L'un des buts de la présente invention est de réaliser une fiche de connexions électriques remédiant à cet inconvénient. One of the aims of the present invention is to produce a plug of electrical connections overcoming this drawback.
La fiche, selon l'invention est du type comportant un élément isolant présentant une série de conduits parallèles destinés a recevoir chacun un organe de contact electrique mâle ou femelle raccordé à un conducteur d'une série de conducteurs loges dans une gaine blindée, ledit organe isolant étant monté dans un boîtier isolant pourvu d'organes permettant de le fixer sur prise, ledit boîtier comportant un organe de blindage externe supportant l'élément isolant et est caractérisée en ce que l'organe de blindage externe est fixé à un organe de blindage complémentaire en emprisonnant l'élément isolant, ledit organe de blindage complémentaire étant logé dans le boîtier isolant et formé par un corps creux destiné à contenir les différe-nts conducteurs et dont l'extrémité opposée à celle fixée au blindage externe est terminée par un col destiné à enserrer la gaine blindée. The plug according to the invention is of the type comprising an insulating element having a series of parallel conduits intended each to receive a male or female electrical contact member connected to a conductor of a series of conductors housed in a shielded sheath, said member insulator being mounted in an insulating box provided with members making it possible to fix it on a socket, said box comprising an external shielding member supporting the insulating element and is characterized in that the external shielding member is fixed to a shielding member complementary by trapping the insulating element, said complementary shielding member being housed in the insulating housing and formed by a hollow body intended to contain the different conductors and whose end opposite to that fixed to the external shielding is terminated by a collar intended to enclose the armored sheath.
Grâce à l'invention, tous les conducteurs sont entièrement protégés par l'organe de blindage complémentaire.Thanks to the invention, all the conductors are fully protected by the complementary shielding member.
De préférence, le boîtier est moule sur l'orga- ne de blindage c-omplémentaire. Preferably, the housing is molded on the c-complementary shielding member.
Suivant un mode de réalisation particulier, le boîtier isolant moulé présente deux canaux dans lesquels sont montées des tiges dont l'une des extrémités est filetée, tandis que l'autre est moletée, chaque tige présentant une partie intermédiaire de plus petit diamètre insérée entre deux épaulements, tandis que les canaux comportent chacun un bourrelet cooperant avec la partie de plus petit diamètre. According to a particular embodiment, the molded insulating housing has two channels in which are mounted rods, one end of which is threaded, while the other is knurled, each rod having an intermediate part of smaller diameter inserted between two shoulders, while the channels each comprise a bead cooperating with the part of smaller diameter.
Enfin, le boîtier isolant moulé comporte deux écrous noyes dans lesquels sont visses des tiges filetees terminees chacunes par un écrou borgne. Finally, the molded insulating housing has two sunken nuts into which threaded rods are screwed, each terminated by a blind nut.
L'invention va maintenant être décrite avec plus de détails en se référant à des modes de réalisation particuliers donnés a titre d'exemple seulement et représen- tés aux dessins annexés, dans lesquels
Figure 1 est une vue en élévation avec des arrachements d'une fiche selon l'invention,
Figure 2 est une vue de la fiche de la figure 1 en élévation de profil, avec des arrachements,
Figure 3 montre en coupe une variante de 1 'inven- tion.The invention will now be described in more detail with reference to particular embodiments given by way of example only and shown in the accompanying drawings, in which
FIG. 1 is an elevation view with cutaway of a plug according to the invention,
FIG. 2 is a view of the plug of FIG. 1 in elevation in profile, with cutaway,
Figure 3 shows in section a variant of the invention.
La fiche représentee aux figures 1 et 2 comprend un élément isolant 1 présentant une série de conduits paral lèles 2 destinés a recevoir chacun un organe de contact mâle ou femelle. L'élément isolant 1 présente un épaulement 3 et repose contre un organe de blindage externe 4 présentant une jupe 5 et un rebord périphérique 6 percé de deux trous 7 situés chacun au voisinage d'une extrémite. The plug shown in Figures 1 and 2 comprises an insulating element 1 having a series of parallel parallel conduits 2 intended to each receive a male or female contact member. The insulating element 1 has a shoulder 3 and rests against an external shielding member 4 having a skirt 5 and a peripheral rim 6 pierced with two holes 7 each located in the vicinity of an end.
Sur le rebord 6 vient coïncider un rebord correspondant 8 d'un organe de blindage complémentaire 9 présentant un épaulement interne 10 destiné à venir porter contre l'épaulement 3 pour assurer le maintien de i'élément isolant 1, ledit rebord 8 présentant des trous 11 correspondant aux trous 7 et étant fixé au rebord 6 par exemple par un sertissage effectué le long des trous 7 et 11. On the rim 6 coincides a corresponding rim 8 of a complementary armor member 9 having an internal shoulder 10 intended to come to bear against the shoulder 3 to ensure the maintenance of the insulating element 1, said rim 8 having holes 11 corresponding to the holes 7 and being fixed to the rim 6 for example by a crimping carried out along the holes 7 and 11.
L'organe de blindage complémentaire 9 présente un corps allonge se terminant du côte opposé à son rebord 11 par un col 12 destiné à recevoir la gaine blindée 13 d'un câble électrique 14, dans lequel s'étendent une série de fils electriques convenablement isolés et destines à être raccorder aux organes de contact mâles ou femelles loges dans les conduits 2. The complementary shielding member 9 has an elongated body terminating on the side opposite its rim 11 by a neck 12 intended to receive the shielded sheath 13 of an electrical cable 14, in which extend a series of suitably insulated electrical wires. and intended to be connected to the male or female contact members housed in the conduits 2.
Au montage le col 12 est soudé à la gaine blindée 13 en un ou plusieurs points 15. During assembly, the neck 12 is welded to the armored sheath 13 at one or more points 15.
L'organe de blindage complémentaire 9 est loge dans un boîtier isolant 17 présentant deux organes 18 pour fixer la fiche à un appareil tel qu'une machine calculatrice, ou a une autre fiche correspondante. The complementary shielding member 9 is housed in an insulating housing 17 having two members 18 for fixing the plug to an apparatus such as a calculating machine, or to another corresponding plug.
Les deux organes 18 sont constitues par des tiges présentant à une extrémité un moletage 19, tandis que l'autre extrémité comporte un filetage 20 traversant les trous 7 et 11. Chaque organe 18 est pourvu d'un épaulement 21 destiné à prendre appui sur la face du rebord 8 opposé a celle coopérant avec le rebord 6 et d'une partie cylindrique 26 dtun diametre inférieur à celui de la tige, cette partie étant raccordée par un épaulement 22. The two members 18 are constituted by rods having at one end a knurling 19, while the other end comprises a thread 20 passing through the holes 7 and 11. Each member 18 is provided with a shoulder 21 intended to bear on the face of the rim 8 opposite to that cooperating with the rim 6 and of a cylindrical part 26 with a diameter smaller than that of the rod, this part being connected by a shoulder 22.
Chaque organe 18 s'étend dans un canal 24 du boîtier 17 présentant un diametre correspondant à celui de la tige avec un bourrelet interne 23 destiné a coopérer avec la partie 26 de plus petit diamètre, de manière que lesdits organes 18 puissent coulisser légèrement et tourner librement dans leur canal respecti-f. Each member 18 extends in a channel 24 of the housing 17 having a diameter corresponding to that of the rod with an internal bead 23 intended to cooperate with the portion 26 of smaller diameter, so that said members 18 can slide slightly and rotate freely in their respective channel.
De préférence le boîtier 17 est moulé directement sur l'organe de blindage 9. Preferably, the housing 17 is molded directly on the shielding member 9.
A la figure 3 on a représenté une variante de réalisation d'une fiche de connexion selon l'invention. La fiche est, sensiblement, la même que celle des figures 1 et 2 et on a utilisé les mêmes références que celles utilisées aux figures précédentes pour designer les organes correspondants, mais affectées de la lettre a
Dans cette variante, le boîtier 17a qui est également moulé sur l'organe de blindage 9a comporte noyé un écrou 30 dans lequel est vissée une tige filetée 31 traversant les trous 7a et lia, des rebords 6a et 8a, ladite tige filetée etant terminée par un écrou borgne 32. On peut ainsi assembler deux fiches dont l'une comporte les organes 18 et l'autre les écrous borgnes 32.In Figure 3 there is shown an alternative embodiment of a connection plug according to the invention. The sheet is, essentially, the same as that of FIGS. 1 and 2 and the same references have been used as those used in the preceding figures to designate the corresponding members, but assigned the letter a
In this variant, the housing 17a which is also molded on the shielding member 9a has embedded a nut 30 into which is screwed a threaded rod 31 passing through the holes 7a and 11a, flanges 6a and 8a, said threaded rod being terminated by a cap nut 32. It is thus possible to assemble two plugs, one of which comprises the members 18 and the other the cap nuts 32.
Bien entendu, l'invention n'est pas limite aux modes de réalisation qui viennent d'être decrits et représentés. Of course, the invention is not limited to the embodiments which have just been described and shown.
On pourra y apporter de nombreuses modifications de détail
sans sortir pour cela du cadre de l'invention. We can make many modifications in detail
without departing from the scope of the invention.
