Description

La présente invention concerne un connecteur électrique a continuité de masse améliorée comportant un embout mâle constitué d'un corps cylindrique métallique dans lequel sont logés une pluralité d'un premier type de contacts et un embout femelle constitué d'un corps cylindrique métallique dans lequel sont logés une pluralité d'un second type de contacts, ainsi que des moyens élastiques de connexions de masse assurant la continuité de masse entre les corps desdits embouts.The present invention relates to an electrical connector with improved mass continuity comprising a male connector made of a metallic cylindrical body in which are housed a plurality of a first type of contacts and a female connector made of a metallic cylindrical body in which are housed a plurality of a second type of contact, as well as elastic mass connection means ensuring mass continuity between the bodies of said end pieces.

Un connecteur de ce type est décrit par exemple dans les brevets européen 41 418 et américain 3 609 632 et 4 239 318. Le connecteur décrit dans ces brevets comporte un embout mâle sur la périphérie extérieure duquel est réalisée une gorge dans laquelle on vient placer un ruban métallique.A connector of this type is described for example in European patents 41 418 and American 3 609 632 and 4 239 318. The connector described in these patents has a male connector on the outer periphery of which is formed a groove in which one comes to place a metallic ribbon.

Ce ruban métallique est maintenu dans la gorge par une rainure. Ce ruban métallique, une fois en place, dépasse légèrement au-dessus de la gorge. Lors de l'accouplement avec l'embout femelle correspondant, ce ruban métallique joue le rôle d'un ressort assurant un bon frottement de l'embout mâle sur l'embout femelle et maintenant l'accouplement de ces deux embouts. Les embouts ayant un corps électriquement conducteur, ce ruban métallique permet d'assure une continuité de masse entre eux de manière à protéger les signaux électriques véhiculés par les contacts de ce connecteur des perturbations hautes fréquences extérieures.This metal strip is held in the groove by a groove. This metallic tape, once in place, protrudes slightly above the throat. When coupling with the corresponding female end piece, this metal strip acts as a spring ensuring good friction of the male end piece on the female end piece and maintaining the coupling of these two end pieces. The ferrules having an electrically conductive body, this metal strip ensures mass continuity between them so as to protect the electrical signals conveyed by the contacts of this connector from external high frequency disturbances.

Cependant; on s'est rendu compte qu'un tel ressort, généralement réalisé sous forme d'un ruban muni de circonvolutions planes afin de permettre son introduction plus aisée dans la gorge correspondante, ne procure qu'un contact de masse de qualité moyenne entre les deux embouts. En particulier, on constate que vis-à-vis des ondes radio-fréquences, électro-magnétiques ainsi que vis-à-vis des impulsions électro-magnétiques, une telle connexion de masse est insuffisante.However; it has been realized that such a spring, generally produced in the form of a ribbon provided with flat convolutions in order to allow its easier introduction into the corresponding groove, provides only a medium-quality ground contact between the two end caps. In particular, it can be seen that with respect to radio frequency, electromagnetic waves as well as with respect to electromagnetic pulses, such a ground connection is insufficient.

Afin d'améliorer la continuité de masse, le connecteur selon l'invention est caractérisé en ce que lesdits moyens élastiques sont constitués par au moins une rangée de doigts élastiques conducteurs cambrés, reliés par l'une de leurs extrémités à une bande métallique continue comportant au moins une rangée de perforations disposées sensiblement parallèlement à la rangée de doigts élastiques, chaque bande métallique, coiffée par une bague de maintien, étant rendue solidaire de l'un des embouts par l'intermédiaire d'au moins un cordon d'un moyen de fixation électriquement conducteur disposé dans une rainure pratiquée dans ledit embout, placé sous une rangée de perforations et traversant celle-ci de manière à solidariser également la bague et ledit embout.In order to improve ground continuity, the connector according to the invention is characterized in that said elastic means consist of at least one row of bent conductive elastic fingers, connected by one of their ends to a continuous metal strip comprising at least one row of perforations arranged substantially parallel to the row of elastic fingers, each metal strip, capped by a retaining ring, being made integral with one of the end pieces by means of at least one cord of a means electrically conductive fastening disposed in a groove formed in said tip, placed under a row of perforations and passing through it so as to also secure the ring and said tip.

De préférence, le moyen de fixation sera constitué par un cordon de brasure, les bagues de maintien étant métalliques.Preferably, the fixing means will consist of a solder bead, the retaining rings being metallic.

Pour améliorer encore la protection du connecteur vis-à-vis des ondes mentionnées plus haut, celui-ci comportera deux rangées parallèles de doigts élastiques reliés entre-eux par une bande métallique munie de perforations, les doigts d'une rangée étant placés en quinconce par rapport à ceux de l'autre rangée.To further improve the protection of the connector against the waves mentioned above, it will include two parallel rows of elastic fingers connected together by a metal strip provided with perforations, the fingers of a row being staggered compared to those in the other row.

Chaque rangée parallèle de doigts élastiques métalliques reliés entre eux par une bande métallique peut être disposée soit à l'intérieur de l'embout femelle (ou embase), soit de préférence à l'extérieur de l'embout mâle, dans une gorge située à proximité de la face avant de cet embout (ou fiche), dans une partie dudit embout mâle qui sera recouverte par l'embout femelle après accouplement.Each parallel row of elastic metal fingers connected to each other by a metal strip can be arranged either inside the female end piece (or base), or preferably outside the male end piece, in a groove located at near the front face of this end piece (or plug), in a part of said male end piece which will be covered by the female end piece after coupling.

Afin de faciliter le montage de la bande métallique et de ses doigts, la bague de maintien la plus proche de la face d'accouplement de l'embout dont elle est solidaire viendra en butée contre un rebord correspondant dudit corps d'embout et portera sur sa face en regard du second embout des premiers moyens de détrompage coopérant avec des seconds moyens de détrompage portés par le second embout. Un tel système d'assemblage permet de simplifier la fabrication des embouts ainsi que le positionnement des clés de détrompage sur les embouts. En effet, il suffit alors, pour un type de connecteur donné, de posséder un corps d'embout unique pour chacun des types mâle et femelle et autant de bagues de fixation qu'on le désire avec les clés de détrompage correspondantes. Ceci permet de rationnaliser les fabrications.In order to facilitate the mounting of the metal strip and its fingers, the retaining ring closest to the coupling face of the endpiece of which it is integral will come into abutment against a corresponding flange of said endpiece body and will bear on its face opposite the second tip of the first polarizing means cooperating with second polarizing means carried by the second tip. Such an assembly system simplifies the manufacture of the end caps as well as the positioning of the keying pins on the end caps. Indeed, it suffices then, for a given type of connector, to have a single tip body for each of the male and female types and as many fixing rings as desired with the corresponding keying keys. This makes it possible to rationalize the manufacturing.

L'invention concerne également un procédé de fabrication d'un embout tel que décrit ci-dessus, procédé dans lequel on créé une rainure dans l'embout correspondant, on place dans cette rainure un cordon de brasure puis on vient placer une bague de maintien au-dessus de cette rainure, on glisse ensuite sous la bague une bande métallique cylindrique perforée portant sur l'un de ses bords des doigts métalliques élastiques cambrés, ladite bande comportant au moins une rangée de perforations placées au-dessus du cordon de brasure, et enfin on place l'embout avec son axe disposé verticalement, dans une enceinte à une température et pendant une durée suffisantes pour faire fondre la brasure qui d'une part traverse alors les perforations pour venir solidariser la bague sur la bande métallique à travers les perforations et d'autre part s'insère entre la bande métallique et la bague ainsi que le corps d'emboutThe invention also relates to a method of manufacturing a nozzle as described above, method in which a groove is created in the corresponding nozzle, a brazing bead is placed in this groove and then a retaining ring is placed above this groove, there is then slipped under the ring a perforated cylindrical metal strip carrying on one of its edges arched elastic metal fingers, said strip comprising at least one row of perforations placed above the brazing bead, and finally the end piece is placed with its axis arranged vertically, in an enclosure at a temperature and for a sufficient time to melt the solder which on the one hand then crosses the perforations to come to secure the ring on the metal strip through the perforations and on the other hand fits between the metal band and the ring as well as the end body

L'invention sera mieux comprise à l'aide des exemples de réalisation suivants donnés à titre non limitatif, conjointement avec les figures qui représentent :

  • - la figure 1, une vue en coupe d'un connecteur selon l'art antérieur;
  • - la figure 2, une vue en coupe du même connecteur avec la modification selon l'invention;
  • - la figure 3, une vue de dessus d'une bande de contact selon l'invention;
  • - la figure 4, une variante de réalisation de la figure 2.
The invention will be better understood with the aid of the following embodiments given without limitation, together with the figures which represent:
  • - Figure 1, a sectional view of a connector according to the prior art;
  • - Figure 2, a sectional view of the same connector with the modification according to the invention;
  • - Figure 3, a top view of a contact strip according to the invention;
  • - Figure 4, an alternative embodiment of Figure 2.

Sur la figure 1, est représentée une vue en coupe d'un connecteur cylindrique de l'art antérieur. Ce connecteur comporte un embout mâle M, un embout femelle F et une bague d'accouplement B pour maintenir l'accouplement des deux embouts M et F. L'embout mâle M comporte un corps cylindrique 1 dans lequel sont logés une pluralité de contacts électriques femelles 10, dont un seul exemplaire est représenté sur la figure. Ce contact électrique 10 traverse, de manière connue en soi, un diélectrique rigide 17 muni d'ouvertures pour le passage des contacts tels que 10, ce diélectrique se terminant par une plaque cylindrique 11 contre lesquels viennent buter les éléments tels que 18 et 19 pour assurer le maintien du contact 10 dans l'embout. Un troisième diélectrique souple 12 sous forme cylindrique est également fixé contre la plaque diélectrique 11, jusqu'à la partie postérieure de l'embout M, d'où émergent les fils électriques tels que 13. Ce diélectrique souple, sous l'effet d'une pression, permet d'assurer l'étanchéité arrière de l'embout M.In Figure 1 is shown a sectional view of a cylindrical connector of the prior art. This connector comprises a male connector M, a female connector F and a coupling ring B to maintain the coupling of the two connectors M and F. The male end piece M comprises a cylindrical body 1 in which are housed a plurality of female electrical contacts 10, of which a single copy is shown in the figure. This electrical contact 10 passes through, in a manner known per se, a rigid dielectric 17 provided with openings for the passage of contacts such as 10, this dielectric ending in a cylindrical plate 11 against which the elements such as 18 and 19 come up against maintain contact 10 in the nozzle. A third flexible dielectric 12 in cylindrical form is also fixed against the dielectric plate 11, up to the rear part of the end piece M, from which electrical wires such as 13 emerge. This flexible dielectric, under the effect of pressure, ensures the rear seal of the nozzle M.

L'embout femelle F comporte un corps cylindrique 2 dans lequel sont logés une pluralité de contacts tels que 9, traversant un corps diélectrique 15 et relié à un fil électrique 14 émergeant sur la face arrière de l'embout femelle (un seul compte prend ensemble contacts 9 et fils 14 a été représenté sur la figure). Le contact mâle 9 fait sailli sur la face avant du diélectrique 15 de manière à permettre sa connexion avec le contact femelle 10 lors de l'accouplement des embouts mâle M et femelle F. Cet accouplement, tel que représenté sur la figure, est maintenu par une bague d'accouplement B venant dans le cas présent se visser sur l'embout femelle F tout en étant maintenu sur l'embout mâle M par une butée 19 solidaire de celui-ci et sur sa face arrière par une rondelle de maintien 4. Pour assurer d'une part un contact, un frottement doux par exemple, entre les deux embouts M et F, et d'autre part un bon contact de masse entre lesdits embouts, est prévue une gorge 7 sur la périphérie extérieure de l'embout mâle M, gorge permettant le logement d'un ressort 8 constitué d'une bande métallique plane munie de circonvolutions, de largeur inférieure à celle de la gorge, et affleurant légèrement au-dessus du niveau supérieur de cette gorge-(voir brevet européen 41 418). De cette manière, on provoque un frottement suffisant à l'accouplement pour maintenir les deux embouts l'un dans l'autre avant le vissage de la bague d'accouplement d'une part et d'autre part une continuité de masse entre les deux embouts M et F en matériau électriquement conducteur.The female endpiece F comprises a cylindrical body 2 in which are housed a plurality of contacts such as 9, passing through a dielectric body 15 and connected to an electric wire 14 emerging on the rear face of the female endpiece (a single account takes together contacts 9 and wires 14 has been shown in the figure). The male contact 9 projects from the front face of the dielectric 15 so as to allow its connection with the female contact 10 during the coupling of the male M and female F ends. This coupling, as shown in the figure, is maintained by a coupling ring B coming in this case to be screwed onto the female endpiece F while being held on the male endpiece M by a stop 19 secured thereto and on its rear face by a retaining washer 4. To ensure on the one hand a contact, a gentle friction for example, between the two end pieces M and F, and on the other hand a good ground contact between said end pieces, a groove 7 is provided on the outer periphery of the end piece male M, groove for housing a spring 8 consisting of a flat metal band provided with convolutions, of width less than that of the groove, and flush slightly above the upper level of this groove- (see European patent 41 418). In this way, sufficient friction is produced during coupling to maintain the two ferrules one inside the other before the coupling ring is screwed on the one hand and a ground continuity between the two ferrules M and F of electrically conductive material on the other hand.

Cette continuité de masse s'avère insuffisante pour la protection contre les signaux de radio-fréquence (RFI), les signaux électro-magnétiques (EMI) et les impulsions électro-magnétiques (EMP). Le connecteur de la figure 1 a été modifié de manière a assurer une continuité de masse améliorée entre les deux embouts tout en assurant la fonction de maintien élastique entre ceux-ci.This ground continuity is insufficient for protection against radio frequency signals (RFI), electromagnetic signals (EMI) and electromagnetic pulses (EMP). The connector of FIG. 1 has been modified so as to ensure an improved mass continuity between the two ends while ensuring the elastic retaining function between them.

La figure 2 représente un connecteur à continuité de masse améliorée selon l'invention. Sur cette figure, les mêmes éléments que ceux de la figure précédente portent les mêmes références. Le corps cylindrique de l'embout mâle M a été modifié au niveau des moyens élastiques de maintien et de continuité de masse. Il comporte deux gorges 305, 306 dans lesquelles sont disposés un cordon de soudure, sur lequel on a placé des bandes de doigts élastiques formant contact et tenus en rive (voir figure 3), contacts représentés sur cette figure par les repères 304 et 302. Sur la bande métallique commune aux contacts tels que 304, bande métallique munie de perforations (voir figure 3) est disposée une bague cylindrique 200 sous laquelle on est venu glisser la partie 330 de cette bande. Cette bague métallique comporte une gorge dans laquelle s'introduit la bande métallique 350. La hauteur de cette bague est inférieure à la hauteur des contacts 304 et 302 afin, bien entendu, de ne pas gêner l'accouplement et le contact électrique entre les deux embouts. Le contact 302 est, quant à lui, disposé avec sa bande métallique 350 munie de perforations 331, 332, 333, ... également au-dessus de la gorge 306 munie d'un cordon de soudure 301, bande métallique de tenue des contacts étant elle-même maintenue en place par une bague 300. Cette bague 300 est en contact étroit en 351 avec le corps 100 de l'embout mâle et vient en butée contre 352 à l'aide, du décrochement 353, la hauteur de ce décrochement étant suffisante pour tolérer l'introduction de la bande métallique telle que 350 sous cette bague 300. Celle-ci possède également dans sa partie supérieure des détrompages 354 coopérant avec des rainures adaptées dans l'embout femelle F.FIG. 2 represents a connector with improved ground continuity according to the invention. In this figure, the same elements as those of the previous figure have the same references. The cylindrical body of the male end piece M has been modified at the level of the elastic means for holding and continuity of mass. It has two grooves 305, 306 in which are placed a weld bead, on which bands of elastic fingers forming a contact are placed and held on the edge (see FIG. 3), contacts represented in this figure by the references 304 and 302. On the metal strip common to the contacts such as 304, a metal strip provided with perforations (see FIG. 3) is arranged a cylindrical ring 200 under which the part 330 of this strip has been slid. This metal ring has a groove into which the metal strip 350 is introduced. The height of this ring is less than the height of the contacts 304 and 302 so, of course, so as not to hinder the coupling and the electrical contact between the two end caps. The contact 302 is, for its part, arranged with its metal strip 350 provided with perforations 331, 332, 333, ... also above the groove 306 provided with a weld bead 301, metal strip holding the contacts being itself held in place by a ring 300. This ring 300 is in close contact at 351 with the body 100 of the male end piece and comes into abutment against 352 by means of the recess 353, the height of this recess being sufficient to tolerate the introduction of the metal strip such as 350 under this ring 300. The latter also has in its upper part of the coding 354 cooperating with adapted grooves in the female endpiece F.

Un tel connecteur présente en outre l'avantage d'une conception modulaire permettant notamment de fixer une bague 300 portant des clés de détrompage telles que 354 variable d'un embout M à l'autre tout en conservant la même structure de base 100 pour cet emboutSuch a connector also has the advantage of a modular design allowing in particular to fix a ring 300 carrying keying keys such as 354 variable from one end piece M to the other while retaining the same basic structure 100 for this mouthpiece

La réalisation de l'embout M complet selon l'invention se déroule selon le procédé ci-après :The production of the complete nozzle M according to the invention takes place according to the following method:

Sur un embout 100 muni de ses gorges 305, 306 (dans le cas d'une seule rangée de doigts de contacts tels que 304 ou 302, l'embout ne comporterait qu'une gorge de même en cas de pluralités de rangées de contacts, de nombre de gorges, est identique au nombre de rangées fixé), on place dans ces gorges un cordon de soudure 303, 301 puis on vient positionner le manchon de la bague 200. On place ensuite la partie 330 de la bande métallique 350 munie de ses perforations 331, 332, 333, etc... (voir figure 3) et de ses doigts de contact 302, 312, 322, etc... sous ladite bague de manière à ce que les perforations 331, 332, 333, etc... soient situées sensiblement au-dessus du cordon de soudure correspondant 303, 301. On positionne ensuite la deuxième série de contacts telle que 302 avec les perforations au-dessus de la gorge et du cordon de soudure correspondant, de la même manière que précédemment par rapport à la bague 300. On place ensuite l'ensemble de l'embout dans une enceinte à une température suffisante pour faire fondre la brasure et pendant une durée suffisante pour que cette brasure permette par capilarité la fixation à travers les ouvertures 331, 332, 333, etc... des bagues telles que 200 et 300 à l'embout proprement dit 100. De préférence, au cours de cette étape de soudure desdites bagues, on placera l'embout verticalement (cet embout est représenté horizontalement sur la figure) de manière à permettre une diffusion de la soudure par capillarité entre le ruban métallique 350 et le corps 100 d'une part ainsi qu'entre le ruban métallique 350 et la bague 200 d'autre part afin d'assurer une meilleure connexion de masse et une meilleure fixation mécanique de l'ensemble. Afin d'éviter la diffusion de la soudure vers les contacts 302, 304, la bague 300 sera placée en position inférieure par rapport à la bague 200. Bien entendu, il est également possible tout en obtenant des résultats moins bons du point de vue continuité de masse mais nettement améliorés par rapport à l'art antérieur, de placer dans les gorges telles que 305 et 306 un cordon de colle telle qu'une colle conductrice époxy mono ou bi-composant, polyuréthane, etc... de manière à assurer la solidarisation de la bague de la bande métallique et le corps d'embout 100.On a ferrule 100 provided with its grooves 305, 306 (in the case of a single row of contact fingers such as 304 or 302, the ferrule would only have one groove likewise in the event of pluralities of rows of contacts, number of grooves, is identical to the number of rows fixed), a weld bead 303, 301 is placed in these grooves, then the sleeve of the ring 200 is positioned. Then place part 330 of the metal strip 350 provided with its perforations 331, 332, 333, etc ... (see Figure 3) and its contact fingers 302, 312, 322, etc ... under said ring so that the perforations 331, 332, 333, etc ... are located substantially above the corresponding weld bead 303, 301. The second series of contacts is then positioned such as 302 with the perforations above the groove and the corresponding weld bead, in the same way as previously with respect to the ring 300. The entire end piece is then placed in an enclosure at a temperature ture sufficient to melt the solder and for a sufficient time for this solder to allow by capillary fixing through the openings 331, 332, 333, etc ... rings such as 200 and 300 to the tip itself 100. Preferably, during this step of welding said rings, the end piece will be placed vertically (this end piece is shown horizontally in the figure) so as to allow diffusion of the weld by capillarity between the metal strip 350 and the body 100 d on the one hand as well as between the metallic strip 350 and the ring 200 on the other hand in order to ensure a better connection of mass and better mechanical fixing of the assembly. In order to avoid the diffusion of the solder towards the contacts 302, 304, the ring 300 will be placed in a lower position relative to the ring 200. Of course, it is also possible while obtaining less good results from the point of view of continuity mass but markedly improved compared to the prior art, to place in the grooves such as 305 and 306 a bead of glue such as a one or two-component epoxy conductive glue, polyurethane, etc. so as to ensure the joining of the ring of the metal strip and the tip body 100.

De même, les contacts électriques mâles et femelles peuvent être disposés au choix dans l'un ou l'autre des embouts.Likewise, the male and female electrical contacts can be arranged as desired in one or the other of the end pieces.

La figure 4 représente une variante de réalisation de l'invention dans laquelle les bandes métalliques telles que 350 munies de leurs perforations et portant les doigts de contact sont disposées à l'intérieur du corps de l'embout femelle. On munit celui-ci de gorges telles que 405, 406 puis on vient ensuite placer les rubans de contact 401 avec leurs perforations au-dessous des gorges remplies de soudure ou de colle, puis on place successivement la bague 403, la rangée de contacts 402 (placés comme précédemment) et la bague 404 qui vient en butée en 408 contre le corps d'embout et qui porte à sa partie inférieure les détrompages femelle ou mâle coopérant avec des détrompages correspondants tels que 354 de la figure 2. Le procédé de montage est identique au cas de la figure 2 et les avantages qui découlent de la structure modulaire sont les mêmes.FIG. 4 represents an alternative embodiment of the invention in which the metal strips such as 350 provided with their perforations and carrying the contact fingers are arranged inside the body of the female end piece. It is provided with grooves such as 405, 406 then we then place the contact strips 401 with their perforations below the grooves filled with solder or glue, then we place successively the ring 403, the row of contacts 402 (placed as above) and the ring 404 which abuts at 408 against the end piece body and which carries at its lower part the female or male polarizations cooperating with corresponding polarizations such as 354 in FIG. 2. The mounting method is identical to the case of FIG. 2 and the advantages which flow from the modular structure are the same.
