Description

La présente invention vise des fiches de connexions électriques.The present invention relates to electrical connection plugs.

L'invention se rapporte, plus particulièrement, à des fiches destinées à l'alimentation des machines calculatrices telles que des ordinateurs.The invention relates, more particularly, to sheets intended for supplying calculating machines such as computers.

La technique antérieure connaît des fiches qui comprennent une enveloppe métallique dont une extrémité se termine par un conduit destiné à être traversé par un câble blindé comportant une série de conducteurs, tandis que l'autre extrémité se termine par une large ouverture. Dans l'ouverture est logé un berceau pourvu d'ailettes latérales et destiné à recevoir un support isolant supportant une série de contacts électriques reliés aux conducteurs. Sur les ailettes du berceau est fixée une plaquette de retenue du support isolant, ladite plaquette étant prolongée par une jupe circonscrivant les contacts.The prior art knows plugs which include a metal casing, one end of which ends in a conduit intended to be crossed by a screened cable comprising a series of conductors, while the other end ends in a wide opening. In the opening is housed a cradle provided with lateral fins and intended to receive an insulating support supporting a series of electrical contacts connected to the conductors. On the fins of the cradle is fixed a retaining plate of the insulating support, said plate being extended by a skirt circumscribing the contacts.

Le berceau s'engage légèrement à force dans l'ouverture de l'enveloppe et on effectue une soudure le long du bord de l'ouverture et du berceau.The cradle slightly engages in the opening of the envelope and a weld is made along the edge of the opening and the cradle.

Ensuite, on moule sur l'enveloppe un boîtier isolant.Then, an insulating box is molded on the envelope.

Une telle disposition est chère et un nombre important de câblages ainsi réalisés sont endommagés par l'action de la chaleur.Such an arrangement is expensive and a large number of cables thus produced are damaged by the action of heat.

On a également imaginé de réaliser la fiche en assemblant le berceau et la plaquette de retenue du support isolant, puis de fixer sur ledit berceau deux demi-coquilles s'emboîtant l'une sur l'autre et constituant l'enveloppe métallique. Une telle disposition s'est avérée également chère et n'a pas permis d'éviter l'opération de soudage toujours délicate.It has also been imagined to produce the plug by assembling the cradle and the retaining plate of the insulating support, then fixing on said cradle two half-shells which fit one on the other and constitute the metal casing. Such an arrangement has also proved to be expensive and has not made it possible to avoid the always delicate welding operation.

L'un des buts de l'invention est de réaliser une fiche remédiant à ces divers inconvénients.One of the aims of the invention is to produce a file remedying these various drawbacks.

La fiche, selon l'invention, est du type comprenant une enveloppe métallique dont une extrémité est conformée pour présenter un conduit destiné à être traversé par un câble blindé avec une tresse métallique, tandis que l'extrémité opposée supporte, d'une part, un support isolant pourvu d'une série de contacts électriques destinés à être reliés à des conducteurs électriques du câble blindé et, d'autre part, une plaquette pourvue d'une jupe destinée à circonscrire les contacts électriques, ladite enveloppe étant logée dans un boîtier isolant, ladite fiche étant caractérisée en ce que l'enveloppe est réalisée en une seule pièce emboutie pour présenter à son extrémité supportant le support isolant et la plaquette un logement pour recevoir ledit support isolant et deux pattes latérales percées chacune d'un trou, la plaquette présentant des moyens pour sa fixation sur les pattes. Grâce à une telle disposition, on supprime toutes les opérations de soudage.The plug according to the invention is of the type comprising a metal casing, one end of which is shaped to present a conduit intended to be crossed by a screened cable with a metal braid, while the opposite end supports, on the one hand, an insulating support provided with a series of electrical contacts intended to be connected to electrical conductors shielded cable and, on the other hand, a plate provided with a skirt intended to circumscribe the electrical contacts, said envelope being housed in an insulating housing, said plug being characterized in that the envelope is produced in a single stamped part to present at its end supporting the insulating support and the plate a housing for receiving said insulating support and two lateral tabs each pierced with a hole, the plate having means for its attachment to the tabs. Thanks to such an arrangement, all the welding operations are eliminated.

Suivant une caractéristique constructive de détail, la plaquette est pourvue d'oeillets destinés à traverser les trous des pattes et destinés à être épanouis pour assurer la fixation de la plaquette sur les pattes.According to a constructive characteristic of detail, the plate is provided with eyelets intended to pass through the holes of the legs and intended to be opened out to ensure the fixing of the plate on the legs.

Suivant encore une caractéristique constructive de détail, le support isolant présente un épaulement tandis que le logement comporte au voisinage des pattes des emboutis destinés à coopérer avec l'épaulement.According to yet a detail construction characteristic, the insulating support has a shoulder while the housing comprises in the vicinity of the legs of the stampings intended to cooperate with the shoulder.

Le boîtier isolant peut être constitué par une pièce moulée souple et élastique présentant deux ouvertures évasées raccordées à un fond évasé par un rétrécissement et destinées à recevoir moyennant une légère déformation élastique les épanouissements des oeillets.The insulating housing can be constituted by a flexible and elastic molded part having two flared openings connected to a flared bottom by a narrowing and intended to receive with a slight elastic deformation the flourishing of the eyelets.

Suivant une variante de réalisation de l'invention, le boîtier isolant est constitué par une pièce surmoulée sur l'enveloppe, les pattes de cette dernière présentant des languettes destinées à être noyées dans ledit boîtier isolant.According to an alternative embodiment of the invention, the insulating housing is constituted by a part overmolded on the casing, the lugs of the latter having tongues intended to be embedded in said insulating housing.

Afin d'assurer une bonne liaison entre l'enveloppe et la tresse du câble blindé, le conduit de l'enveloppe présente une section à pans coupés et il est inséré entre ledit conduit et la tresse métallique préalablement retournée sur le câble une bague ayant une section correspondante, le conduit et la bague étant sertis sur le câble. Ainsi avec le même outillage, on peut sertir des enveloppes sur des câbles de différents diamètres avec le même outillage et le câble ainsi serti présente une grande résistance à l'arrachement.In order to ensure a good connection between the envelope and the braid of the shielded cable, the conduit of the envelope has a section with cut sides and there is inserted between said conduit and the metal braid previously turned over the cable a ring having a corresponding section, the conduit and the ring being crimped onto the cable. Thus with the same tool, envelopes can be crimped on cables of different diameters with the same tool and the cable thus crimped has a high resistance to tearing.

Suivant encore une caractéristique de détail, la bague comporte une extrémité évasée formant une butée destinée à coopérer avec l'extrémité du conduit tournée vers l'intérieur de l'enveloppe.According to yet another characteristic of detail, the ring has a flared end forming a stop intended to cooperate with the end of the duct turned towards the inside of the envelope.

L'invention va maintenant être décrite avec plus de détails en se référant à des modes de réalisation particuliers donnés à titre d'exemple seulement et représentés aux dessins annexés, dans lesquels :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:

Figure 1 est une vue en perspective éclatée d'une fiche, selon l'invention.Figure 1 is an exploded perspective view of a plug, according to the invention.

Figures 2, 3 et 4 sont des vues schématiques en élévation montrant le montage d'une bague assurant la liaison du blindage avec l'enveloppe métallique.Figures 2, 3 and 4 are schematic elevational views showing the mounting of a ring ensuring the connection of the shield with the metal casing.

Figure 5 est une vue schématique en coupe montrant le sertissage de la bague.Figure 5 is a schematic sectional view showing the crimping of the ring.

Figure 6 est une vue en coupe de la fiche terminée.Figure 6 is a sectional view of the completed sheet.

Figure 7 est une vue à plus grande échelle en coupe d'un détail.Figure 7 is an enlarged sectional view of a detail.

Figure 8 et figure 9 sont des vues en coupe d'un détail suivant une variante de réalisation de l'invention.Figure 8 and Figure 9 are sectional views of a detail according to an alternative embodiment of the invention.

Figure 10 est une vue en coupe partielle, à plus grande échelle du support isolant.Figure 10 is a partial sectional view, on a larger scale of the insulating support.

La fiche, selon l'invention, est essentiellement constituée d'une enveloppe métallique 1, d'un support pour des contacts 2 et d'une plaquette de retenue 3.The plug according to the invention essentially consists of a metal casing 1, a support for contacts 2 and a retaining plate 3.

L'enveloppe 1, à une extrémité, présente un conduit 4, tandis que son autre extrémité est terminée par une large ouverture 5.The casing 1, at one end, has a duct 4, while its other end is terminated by a wide opening 5.

L'enveloppe 1 au voisinage de l'ouverture 5 sur deux côtés opposés 6 et 7 présente intérieurement des emboutis 8 qui déterminent un logement pour le support 2, les côtés 6 et 7 étant pourvus chacun d'une patte 9 percée d'un trou 10, ces pattes 9 étant situées dans un même plan que celui de l'ouverture 5.The envelope 1 in the vicinity of the opening 5 on two opposite sides 6 and 7 has internally stampings 8 which determine a housing for the support 2, the sides 6 and 7 each being provided with a tab 9 pierced with a hole 10, these tabs 9 being located in the same plane as that of the opening 5.

Le support 2 est constitué de deux pièces de matière plastique isolante moulées, la première pièce 12 présentant une série de canaux 13 s'ouvrant sur une face 14 et, prolongés sur l'autre face par des lèvres 15 destinées à s'engager dans un logement 16 de la pièce 20.The support 2 consists of two pieces of molded insulating plastic, the first piece 12 having a series of channels 13 opening on one face 14 and, extended on the other face by lips 15 intended to engage in a housing 16 of room 20.

Les lèvres 15 débouchent dans un logement destiné à recevoir une saillie 19 de la seconde partie 20.The lips 15 open into a housing intended to receive a projection 19 of the second part 20.

La seconde partie 20 est percée d'une série de canaux 21 destinés à être alignés avec les canaux 13 et débouchant du côté correspondant dans les logements 16.The second part 20 is pierced with a series of channels 21 intended to be aligned with the channels 13 and emerging on the corresponding side in the housings 16.

La partie 12 est terminée par un épaulement 22 et la partie 20 comporte un épaulement correspondant 23 destiné à coopérer avec l'épaulement 22.Part 12 is terminated by a shoulder 22 and part 20 has a corresponding shoulder 23 intended to cooperate with shoulder 22.

Les parties 12 et 20 sont destinées à être assemblées par collage, soudure ou autre et l'ensemble ainsi formé est destiné à être engagé dans l'enveloppe 1, l'épaulement 22 venant buter contre les emboutis 8 pour limiter l'engagement.The parts 12 and 20 are intended to be assembled by gluing, welding or other and the assembly thus formed is intended to be engaged in the casing 1, the shoulder 22 abutting against the stampings 8 to limit engagement.

La plaquette de retenue 3 est constituée d'une pièce métallique emboutie pour présenter un rebord 24 avec deux ailes 25 dans chacune desquelles est conformé un oeillet 26 en saillie sur une face, et, en saillie sur l'autre face, une jupe 27.The retaining plate 3 consists of a stamped metal part to present a rim 24 with two wings 25 in each of which is formed an eyelet 26 projecting from one side, and, projecting from the other side, a skirt 27.

La plaquette 3 est destinée à venir coopérer avec le bord, de l'enveloppe 1 pour retenir le support 2, les oeillets 26 étant insérés dans les trous 10 et épanouis pour assurer la fixation de la plaquette 3.The plate 3 is intended to cooperate with the edge of the envelope 1 to retain the support 2, the eyelets 26 being inserted in the holes 10 and opened out to ensure the fixing of the plate 3.

Le conduit 4 affecte une forme hexagonale et, comme on le voit aux différentes figures 2,3,4 et 5, il est destiné à coopérer avec une bague hexagonale 35.The duct 4 has a hexagonal shape and, as can be seen in the different figures 2,3,4 and 5, it is intended to cooperate with a hexagonal ring 35.

La fiche est destinée à recevoir un câble blindé 30 comportant une gaîne extérieure 31, une tresse 32, un drain 33 et des conducteurs isolés 37.The plug is intended to receive a shielded cable 30 comprising an outer sheath 31, a braid 32, a drain 33 and insulated conductors 37.

La gaîne extérieure 31 est découpée afin de laisser dépasser la tresse et le drain qui sont rabattus sur ladite gaîne, la bague hexagonale étant engagée sur ladite extrémité. Cette bague 35 présente une extrémité 36 légèrement évasée qui constitue une butée.The outer sheath 31 is cut in order to allow the braid and the drain which are folded over said sheath to protrude, the hexagonal ring being engaged on said end. This ring 35 has a slightly flared end 36 which constitutes a stop.

Les extrémités des conducteurs 37, dans ce mode de réalisation reçoivent des organes de contact mâles 40 qui présentent une partie 41 fixée au conducteur, un épaulement 42 destiné à porter contre le fond du logement 16 et une extrémité libre 43 destinée à traverser un canal correspondant 21 et à faire saillie à l'extrémité correspondante de la partie 20 pour s'étendre dans la jupe 27.The ends of the conductors 37, in this embodiment receive male contact members 40 which have a part 41 fixed to the conductor, a shoulder 42 intended to bear against the bottom of the housing 16 and a free end 43 intended to pass through a corresponding channel 21 and to project at the corresponding end of the part 20 to extend into the skirt 27.

Pour réaliser un câblage avec la fiche, selon l'invention, on engage en premier sur le câble 30 l'enveloppe 1, celle-ci traversant le conduit 4, on prépare le câble comme montré aux figures 2, 3 et 4 et on met en place les contacts 40, puis on soude les parties 12 et 20. On fait ensuite glisser l'enveloppe afin, d'une part, que son conduit 4 vienne coopérer avec la bague 35, et, d'autre part, que le support 2 vienne se loger dans l'enveloppe en butant contre les emboutis 8, puis la plaquette de retenue 3 est posée, ses oeillets étant engagés dans les trous 10 et épanouis.To carry out wiring with the plug, according to the invention, the casing 1 is first engaged on the cable 30, the latter passing through the conduit 4, the cable is prepared as shown in FIGS. 2, 3 and 4 and one puts in place the contacts 40, then the parts 12 and 20 are welded. The envelope is then slid so that, on the one hand, its duct 4 comes to cooperate with the ring 35, and, on the other hand, that the support 2 comes to be housed in the envelope abutting against the pressed 8, then the retaining plate 3 is placed, its eyelets being engaged in the holes 10 and flourished.

On procède ensuite à une opération de sertissage sur le conduit 4 afin, d'une part, qu'il épouse la bague 35 et, d'autre part, que le câble 30 soit enserré.Then a crimping operation is carried out on the conduit 4 so that, on the one hand, it matches the ring 35 and, on the other hand, that the cable 30 is clamped.

Grâce au fait que la bague 35 et le conduit 4 présentent des pans coupés, on peut utiliser les mêmes outils pour diamètres différents. De plus, le câble 30 est mieux tenu et présente une plus grande résistance à l'arrachement.Thanks to the fact that the ring 35 and the conduit 4 have cut sides, the same tools can be used for different diameters. In addition, the cable 30 is better held and has greater resistance to tearing.

La fiche est complétée par un boîtier isolant 50. Ce boîtier 50 (voir figures 6 et 7) peut être moulé séparément et mis en place sur le câble 30 avant la pose de l'enveloppe.The plug is completed by an insulating housing 50. This housing 50 (see FIGS. 6 and 7) can be molded separately and put in place on the cable 30 before the envelope is laid.

Ce boîtier isolant 50 est de préférence réalisé en matière plastique souple et élastique et présente deux conduits 51 destinés à être traversés par des vis 52 de fixation de la fiche sur une machine.This insulating housing 50 is preferably made of flexible and elastic plastic material and has two conduits 51 intended to be crossed by screws 52 for fixing the plug to a machine.

Chaque conduit, à son extrémité correspondante comporte une ouverture évasée 54 raccordée à un fond évasé 55 par un rétrécissement 56. Grâce à cette disposition lors de la mise en place du boîtier sur l'enveloppe 1, les oeillets 26 s'engagent dans la partie évasée 54 et, moyennant une déformation élastique du rétrécissement 56, viennent se loger dans le fond 55. Ainsi on assure d'une manière très simple et très efficace la fixation entre le boîtier et l'enveloppe.Each conduit, at its corresponding end has a flared opening 54 connected to a flared bottom 55 by a narrowing 56. Thanks to this arrangement when the housing is placed on the casing 1, the eyelets 26 engage in the flared part 54 and, by means of an elastic deformation of the constriction 56, are housed in the bottom 55. Thus, the fixing between the casing and the envelope is very simple and effective.

On peut également, comme montré schématiquement aux figures 8 et 9, surmouler le boîtier sur l'enveloppe. Dans ce cas on prévoit, découpées dans les pattes 9a, des languettes 55 qui, en plus des oeillets 26, sont noyées dans la matière constituant le boîtier 50a.It is also possible, as shown diagrammatically in FIGS. 8 and 9, to overmold the housing on the envelope. In this case there is provided, cut in the legs 9a, tongues 55 of which, in addition to eyelets 26, are embedded in the material constituting the housing 50 a.

On conçoit que la fiche, selon l'invention, par rapport à la technique antérieure connue, présente de nombreux avantages et notamment elle évite les soudures qui présentent toujours de nombreux inconvénients.It is understood that the plug, according to the invention, compared to the known prior art, has many advantages and in particular it avoids the welds which always have many disadvantages.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits et représentés. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the embodiments which have just been described and shown.
