Description

Dispositif de liaison entre un connecteur électrique et un câble électrique coaxial blindé et connecteur électrique correspondant Connecting device between an electrical connector and a shielded coaxial electrical cable and corresponding electrical connector
La présente invention se rapporte à un dispositif de liaison entre un connecteur électrique et un câble électrique coaxial blindé.The present invention relates to a connection device between an electrical connector and a shielded coaxial electrical cable.
Dans le but de réduire les perturbations électromagnétiques engendrées par le passage d'un courant électrique dans un câble électrique, surtout lors du transfert de courant à forte puissance électrique, les câbles électriques sont équipés d'un dispositif de blindage électromagnétique tel qu'illustré dans le document FR2858719. Un tel câble blindé se présente sous la forme d'un câble coaxial, comportant un conducteur central, un isolant entourant le conducteur central et une tresse (tresse de masse) entourant à son tour l'isolant. Le tout est maintenu et protégé à l'intérieur d'une gaine.In order to reduce the electromagnetic disturbances caused by the passage of an electric current in an electric cable, especially during the transfer of high power current, the electric cables are equipped with an electromagnetic shielding device as illustrated in FIG. FR2858719. Such shielded cable is in the form of a coaxial cable, having a central conductor, an insulator surrounding the central conductor and a braid (ground braid) surrounding the insulation in turn. Everything is held and protected inside a sheath.
La tresse de masse forme un écran électromagnétique. Pour qu'un tel blindage électromagnétique soit efficace, il faut qu'à chaque extrémité du câble, la tresse soit reliée à la masse. Pour réaliser une connexion optimale du câble sur le connecteur, il faut que l'isolant, la tresse et la gaine soient coupées, dans un premier temps, respectivement, sur une longueur suffisante par rapport aux extrémités du câble pour libérer le conducteur électrique devant être relié à une borne électrique d'un circuit électrique. Pour relier les extrémités de la tresse à la masse, il est nécessaire de dénuder les extrémités de la gaine pour libérer les extrémités de la tresse. Une bague métallique, reliée à la masse, est généralement sertie autour de cette tresse pour réaliser la liaison électrique entre la tresse et la masse. Une autre solution peut consister à souder un fil de masse sur cette tresse.The mass braid forms an electromagnetic screen. For such an electromagnetic shielding to be effective, it is necessary that at each end of the cable, the braid is connected to ground. To achieve an optimal connection of the cable on the connector, it is necessary that the insulation, the braid and the sheath are cut, at first, respectively, over a sufficient length relative to the ends of the cable to release the electrical conductor to be connected to an electrical terminal of an electrical circuit. To connect the ends of the braid to ground, it is necessary to strip the ends of the sheath to release the ends of the braid. A metal ring, connected to the ground, is usually crimped around this braid to make the electrical connection between the braid and the ground. Another solution may be to weld a ground wire on this braid.
L'assemblage de la bague métallique autour de la tresse représente une opération de grande précision, nécessitant une force de serrage suffisante pour assurer un contact électrique suffisant, mais risquant en cas de trop fort serrage, d'endommager la tresse ou l'isolant. L'assemblage par un fil électrique soudé présente une efficacité électromagnétique moindre à haute fréquence, ne convenant pas à toutes les applications d'un tel connecteur. L'objet de l'invention est de proposer un moyen industriellement simple à réaliser, permettant de raccorder un câble blindé à un connecteur électrique, assurant une pression de serrage constante du connecteur sur la tresse extérieure d'un tel câble coaxial évitant tout risque de dégradation de la tresse ou de l'isolant recouvert par cette tresse.The assembly of the metal ring around the braid is an operation of high precision, requiring a sufficient clamping force to ensure sufficient electrical contact, but risking in case of too much tightening, damaging the braid or insulation. The assembly by a welded wire has a lower electromagnetic efficiency at high frequency, not suitable for all applications of such a connector. The object of the invention is to provide an industrially simple means to achieve, for connecting a shielded cable to an electrical connector, ensuring a constant clamping pressure of the connector on the outer braid of such a coaxial cable avoiding any risk of degradation of the braid or insulation covered by this braid.

Le connecteur 1 comporte deux parties principales : un socle 11 formant l'embase du connecteur 1 et un couvercle 12. Le câble blindé 2 comporte une âme (ou conducteur) centrale 21 servant à conduire du courant électrique, un isolant électrique 22 entourant cette âme 21 sur toute la longueur du câble et servant à isoler l'âme 21 d'une tresse de masse 23. La tresse 23 qui s'étend sur toute la longueur du câble 2, entoure l'âme 21. Cette tresse 23 forme un écran électromagnétique au champ rayonné par le courant électrique circulant dans l'âme 21 du câble 2. Ce câble 2 présente une gaine extérieure 24 isolant et protégeant la tresse 23 de l'environnement extérieur. Le câble 2 est fixé par une de ses extrémités au connecteur 1. A cette extrémité, l'âme centrale 21 du câble 2 est dénudée sur une longueur suffisante pour permettre le montage d'une cosse plate à œil 25 sur l'âme. Cette cosse à œil 25 présente une ouverture circulaire 26, permettant, comme expliqué ultérieurement, d'assurer une bonne connexion électrique avec un contact positionné sur le socle 1 1. La longueur de la tresse 23 est ajustée pour ne pas dépasser de l'isolant électrique 22 évitant tout risque de contact avec l'âme centrale 21 ou avec la cosse 25. La tresse 23 est dénudée sur une longueur suffisante pour permettre une connexion électrique avec deux éléments conducteurs 3 disposés dans le socle 11. Les éléments conducteurs 3 se présentent respectivement sous la forme d'une bande inférieure 31 , portée par le socle 11 , et d'une bande supérieure 32, portée par le couvercle 12. Ces deux bandes 3 présentent, au moins sur les faces en regard l'une de l'autre, un revêtement de surface électriquement conducteur. Les deux bandes 3 sont fixées au socle 11 ou au couvercle 12 par leurs extrémités 33, laissant libre la partie centrale 34 de ces bandes 3. La fixation des deux extrémités 33 de chacune des deux bandes 3 au socle 1 1 et au couvercle 12 peut se faire par un premier collage, assurant un pré-maintien, et par des ouvertures circulaires 35, positionnées en bordure de ces bandes 3, permettant le passage de vis 5 servant par ailleurs à la fixation du couvercle 12 sur le socle 11. Un premier circuit électrique 36 (partiellement représenté) est relié la bande inférieure 31. Le socle 11 du connecteur 1 présente aussi un contact électrique 4 composé d'une plaque conductrice 41 sur laquelle vient se positionner la cosse 25 et un pion 42 qui en venant pénétrer dans l'ouverture circulaire 26 bloque la cosse 25 le long de la plaque conductrice 41 (mais il est aussi possible de se passer d'une telle cosse 25 : l'extrém ité libre de l'âme 21 pouvant être directement connectée au circuit électrique du socle 1 1 ). Un second circuit électrique 43 (partiellement représenté) prolonge la plaque conductrice 41 ; ce second circuit électrique permettant de relier l'âme 21 avec un circuit électrique principal (non représenté).The connector 1 comprises two main parts: a base 11 forming the base of the connector 1 and a cover 12. The shielded cable 2 comprises a central core (or conductor) 21 serving to conduct electrical current, an electrical insulator 22 surrounding this core 21 over the entire length of the cable and serving to isolate the core 21 from a braid of mass 23. The braid 23 which extends over the entire length of the cable 2, surrounds the core 21. This braid 23 forms a screen electromagnetic field radiated by the electric current flowing in the core 21 of the cable 2. This cable 2 has an outer sheath 24 insulating and protecting the braid 23 of the external environment. The cable 2 is fixed at one end to the connector 1. At this end, the central core 21 of the cable 2 is stripped to a length sufficient to allow the mounting of a flat eye lug 25 on the core. This eye terminal 25 has a circular opening 26, allowing, as explained later, to ensure a good electrical connection with a contact positioned on the base 1 1. The length of the braid 23 is adjusted to not exceed the insulation electric 22 avoiding any risk of contact with the central core 21 or with the lug 25. The braid 23 is stripped over a sufficient length to allow electrical connection with two conductive elements 3 disposed in the base 11. The conductive elements 3 are respectively under the form of a lower band 31, carried by the base 11, and an upper band 32, carried by the cover 12. These two strips 3 have, at least on the faces facing each other, a electrically conductive surface coating. The two strips 3 are fixed to the base 11 or the cover 12 by their ends 33, leaving free the central portion 34 of these strips 3. The attachment of the two ends 33 of each of the two strips 3 to the base 1 1 and to the cover 12 may to be done by a first bonding, providing a pre-hold, and by circular openings 35, positioned at the edge of these strips 3, allowing the passage of screws 5 also serving for fixing the cover 12 on the base 11. A first electrical circuit 36 (partially shown) is connected to the lower band 31. The base 11 of the connector 1 also has an electrical contact 4 composed of a conductive plate 41 on which is positioned the pod 25 and a pin 42 which comes into the the circular opening 26 blocks the lug 25 along the conductive plate 41 (but it is also possible to dispense with such a lug 25: the free end of the core 21 can be directly connected to the electrical circuit of the base 1 1). A second electrical circuit 43 (partially shown) extends the conductive plate 41; this second electrical circuit for connecting the core 21 with a main electrical circuit (not shown).
Comme illustré à la figure 2, la tresse 23, préalablement dénudée, est positionnée en contact de la bande inférieure 31 et de la bande supérieure 32 du socle 11. Les vis 5, traversant le couvercle 12 du connecteur 1 dans des trous taraudés 13 du socle 1 1 , assure le serrage du couvercle sur le socle en traversant les ouvertures 35 des bandes 3. Les extrémités correspondantes 33 des bandes inférieure 31 et supérieure 32 sont en contact l'une contre l'autre, assurant une continuité électrique entre la bande supérieure 31 et la bande inférieure 32. Les bandes supérieure 31 et inférieure 32 épousent la forme de la tresse 23, exerçant une pression répartie uniformément le long de la surface de contact avec la tresse 23. Les bandes 3 doivent présenter une élasticité suffisante pour pouvoir s'adapter à des câbles dont le diamètre est compris dans une certaine fourchette de tolérance, tout en maintenant sur ces câbles une pression suffisante pour garantir un bon contact électrique. La pression de contact doit aussi rester en dessous d'un certain seuil pour ne pas blesser la tresse 23 et/ou l'isolant 22. Les figures 3 à 5 représentent différents modes de réalisation d'une bande 3 présentant une conductivité électrique optimale et une élasticité adaptée telles qu'expliquées précédemment.As illustrated in FIG. 2, the braid 23, previously stripped, is positioned in contact with the lower band 31 and the upper band 32 of the base 11. The screws 5, passing through the cover 12 of the connector 1 in tapped holes 13 of the base 1 1, ensures the tightening of the cover on the base through the openings 35 of the strips 3. The corresponding ends 33 of the lower 31 and upper 32 strips are in contact with one another, ensuring electrical continuity between the band upper and lower bands 32. The upper and lower bands 32 follow the shape of the braid 23, exerting a uniformly distributed pressure along the contact surface with the braid 23. The bands 3 must have sufficient elasticity to be able to adapt to cables whose diameter is included in a certain tolerance range, while maintaining on these cables a sufficient pressure to guarantee a good electrical contact. The contact pressure must also remain below a certain threshold in order not to injure the braid 23 and / or the insulator 22. FIGS. 3 to 5 represent various embodiments of a strip 3 having optimum electrical conductivity and a suitable elasticity as explained previously.
Un premier mode de réalisation, illustré en figure 3, représente une bande 3a continue entièrement métallique. La bande 3a comporte des pliures 6 disposées transversalement le long de la partie centrale 34a de la bande 3a, espacées par des segments plats, assurant autant de surfaces de contact avec la tresse 23. Les pliures 6 sont formées de deux lamelles 61 planes contigϋes formant un V ; les surfaces de contact et les pliures étant disposées en accordéon. La profondeur des lamelles 61 formant les pliures 6 en V, ainsi que le métal utilisé, généralement des aciers HLE à forte teneur en carbone, permettent de faire varier la pression appliquée par la bande 3a sur la tresse 23. Pour améliorer la conductivité électrique d'une telle bande métallique 3a, une couche d'un métal offrant de bonnes qualités de conductivité, tel que du cuivre, peut recouvrir la surface de la bande 3a destinée à venir en contact avec la tresse 23.A first embodiment, illustrated in FIG. 3, represents an entirely metallic continuous strip 3a. The band 3a has folds 6 arranged transversely along the central portion 34a of the band 3a, spaced apart by flat segments, providing as many contact surfaces with the braid 23. The folds 6 are formed of two flat plates 61 contiguous forming a V ; the contact surfaces and the folds being arranged accordionally. The depth of the strips 61 forming the V-shaped folds 6, as well as the metal used, generally HLE steels with a high carbon content, make it possible to vary the pressure applied by the strip 3a on the braid 23. To improve the electrical conductivity of the Such a metal strip 3a, a layer of a metal having good conductivity qualities, such as copper, can cover the surface of the strip 3a intended to come into contact with the braid 23.
Un second mode de réalisation, illustré en figure 4, représente une bande 3b en deux parties. Une première partie formant une lame métallique 71 recouvre une seconde partie formant une bande en élastomère 72, par exemple en caoutchouc ; la lame métallique 71 étant fixée sur la bande en élastomère 72. La fixation de la lame métallique sur la bande en élastomère peut se faire par vulcanisation de la bande en élastomère 72 sur la lame métallique 71 qui présentera alors une surface de contact favorisant un tel maintien. La lame métallique 71 comporte une série de découpes 73 s'étendant alternativement à partir de ses deux bords longitudinaux et, transversalement le long de la partie centrale 34b de la bande 3b. La bande 3b présente ainsi un circuit en forme de serpentin formé par le parcours de la lame métallique 71 sur la bande en élastomère 72, avec les découpes 73 pouvant s'écarter les unes des autres, pour permettre un allongement de la bande 3b. La bande en élastomère 72 assure l'élasticité de la bande 3b resserrant les découpes 73 les unes contre les autres une fois la pression sur la lame 3b relâchée. La lame métallique 71 peut être directement réalisée dans un métal souple assurant une bonne conductivité électrique, tel que du cuivre.A second embodiment, illustrated in FIG. 4, represents a band 2b in two parts. A first portion forming a metal blade 71 covers a second portion forming an elastomeric strip 72, for example rubber; the metal blade 71 being fixed on the elastomer strip 72. The metal blade is fixed on the elastomer strip by vulcanizing the elastomer strip 72 on the metal strip 71, which will then have a contact surface promoting such maintenance. The metal blade 71 has a series of cuts 73 extending alternately from its two longitudinal edges and transversely along the central portion 34b of the band 3b. The strip 3b thus has a serpentine-shaped circuit formed by the path of the metal blade 71 on the elastomeric strip 72, with the cutouts 73 being able to deviate from each other, to allow elongation of the strip 3b. The elastomeric strip 72 provides the elasticity of the band 3b tightening the cuts 73 against each other. other once the pressure on the blade 3b released. The metal blade 71 may be directly made of a flexible metal providing good electrical conductivity, such as copper.
En figure 5, est représentée une variante du second mode de réalisation d'une bande 3c présentant une lame métallique 81 et une bande en élastomère 82. La lame métallique 81 , réalisée dans un métal souple, présente une alternance de boucles 83 et de segments plats 84. La lame 81 est fixée sur une bande en élastomère 82. Les boucles 83, laissées libre, traversent la bande en élastomère 82, laissant en contact avec la bande en élastomère 82 les faces intérieures des segments plats 84. Les faces extérieures des segments plats 84 sont destinées à venir en contact avec la tresse 23. La bande en élastomère 82 permet de contrôler l'écartement des boucles 83, allongeant la bande 8 et assurant son élasticité. Comme pour le second mode de réalisation, la lame en métal peut être directement constituée de cuivre, permettant une bonne conductivité électrique avec la tresse 23.FIG. 5 shows a variant of the second embodiment of a strip 3c having a metal strip 81 and an elastomeric strip 82. The metal strip 81, made of a flexible metal, has alternating loops 83 and segments. 84. The blade 81 is fixed on an elastomeric strip 82. The loops 83, left free, pass through the elastomeric strip 82, leaving in contact with the elastomeric strip 82 the inner faces of the flat segments 84. The outer faces of the Flat segments 84 are intended to come into contact with the braid 23. The elastomer strip 82 makes it possible to control the spacing of the loops 83, lengthening the strip 8 and ensuring its elasticity. As for the second embodiment, the metal blade may be directly made of copper, allowing good electrical conductivity with the braid 23.
Dans certaines situations, notamment pour une application dans un véhicule automobile, il est important qu'un tel connecteur 1 présente des surfaces de contacts avec le câble 2 étanchéifiés, évitant une oxydation des surfaces de contact soumis à un environnement humide. Pour ce faire, le socle 1 1 et l e couvercl e 1 2 peuvent présenter d es su rfaces d e contact complémentaires permettant, par le positionnement d'un joint d'étanchéité le long de cette surface de contact, d'assurer une partie de l'étanchéité. Un étamage est pratiqué sur les surfaces latérales des bandes 3, pour protéger de l'oxydation les contacts et assurer l'étanchéité de cette partie du montage. Le socle 1 1 et le couvercle 12, une fois assemblés, présentent au niveau du passage du câble 2 une ouverture cylindrique d'un diamètre proche du diamètre du câble 2, avec un joint d'étanchéité assurant l'étanchéité entre la gaine extérieure 24 du câble 2 et le connecteur 1.In certain situations, particularly for application in a motor vehicle, it is important that such a connector 1 has contact surfaces with the cable 2 sealed, avoiding oxidation of the contact surfaces subjected to a humid environment. To do this, the base 1 1 and the lid 1 2 may have additional contact suffaces allowing, by the positioning of a seal along this contact surface, to ensure a part of the sealing. A tinning is performed on the side surfaces of the strips 3 to protect the contacts from oxidation and to seal this part of the assembly. The base 1 1 and the cover 12, once assembled, have at the passage of the cable 2 a cylindrical opening with a diameter close to the diameter of the cable 2, with a seal ensuring the seal between the outer sheath 24 cable 2 and connector 1.
Le connecteur peut aussi permettre la connexion de plusieurs câbles 2, en parallèle, avec une même bande supérieure et inférieure venant enserrer simultanément les tresses 23 des différents câbles. Le socle ou le couvercle présentent des surfaces d'appui qui coopèrent avec les parties droites de la bande séparant chaque câble. Ces parties droites assurent une succession de points de contact entre la bande supérieure et la bande inférieure. II est bien entendu que l'invention n'est pas limitée aux modes de réalisation qui ont été décrits, mais est susceptible de recevoir de nombreuses modifications qui apparaîtront à l'homme du métier. Notamment, concernant l'obtention des bandes 3 qui doivent présenter à la fois une bonne conductivité électrique et présentant l'élasticité voulue. The connector may also allow the connection of several cables 2, in parallel, with the same upper and lower band simultaneously gripping the braids 23 of the different cables. The base or cover has bearing surfaces that cooperate with the straight portions of the strip separating each cable. These straight portions provide a succession of contact points between the upper band and the lower band. It is understood that the invention is not limited to the embodiments that have been described, but is likely to receive many changes that will occur to those skilled in the art. In particular, concerning the obtaining of strips 3 which must have both good electrical conductivity and having the desired elasticity.
