Après assemblage des deux éléments 10, les blindages 30 forment en combinaison quatre alvéoles qui logent chacune une paire de contact 41-47, comme on le voit notamment sur la figure 4.After assembly of the two elements 10, the shields 30 form in combination four cells each housing a pair of contact 41-47, as can be seen in particular in FIG. 4.

Plus précisément, le connecteur connu illustré sur les figures 1 à 4 annexées comprend un élément 10 formant fiche et un élément 10 formant prise. Les interfaces étant identiques, la distinction entre la fiche et la prise est faite par l'utilisation de deux coques externes en matière plastique métallisée intérieurement pour assurer la continuité du blindage. Une coque est dite mâle, l'autre femelle. Les deux coques sont munies de détrompeurs mécaniques évitant l'inversion du sens d'enfichage.More specifically, the known connector illustrated in appended FIGS. 1 to 4 comprises a plug member 10 and a plug member 10. Since the interfaces are identical, the distinction between the plug and the plug is made by the use of two external shells of metallised plastic internally to ensure the continuity of the shielding. One hull is called male, the other female. Both shells are equipped with mechanical keying devices, avoiding the inversion of the plugging direction.

Bien qu'ayant rendu de grands services, ce connecteur connu ne donne pas totalement satisfaction.Although having rendered great services, this known connector does not give complete satisfaction.

En particulier, il s'avère à l'utilisation que ce connecteur connu présente des fuites importantes au niveau du plan de joint électromagnétique, référencé 60, 62 sur les figures 1 à 4, correspondant au plan de joint longitudinal défini entre les blindages 30 des deux éléments 10.In particular, it turns out that this known connector has significant leaks at the level of the electromagnetic seal plane, referenced 60, 62 in Figures 1 to 4, corresponding to the longitudinal joint plane defined between the shields 30 of the two elements 10.

De plus, la partie arrière interfaciale du connecteur connu présente une discontinuité du blindage entre les contacts auto-dénudants.In addition, the interfacial rear portion of the known connector has a shielding discontinuity between the insulation-removing contacts.

Enfin, les coquilles métallisées complétant ce connecteur connu n'assurent pas un blindage satisfaisant.Finally, the metallized shells completing this known connector do not provide satisfactory shielding.

Par conséquent, l'effet "tunnel" des alvéoles n'est pas assuré d'un bout à l'autre du connecteur.Consequently, the "tunnel" effect of the cells is not ensured from one end to the other of the connector.

Le document EP-A-0562691 divulgue un connecteur électrique également destiné à des fréquences élevées qui comprend un premier élément support en matériau électriquement isolant qui définit une pluralité d'alvéoles recevant des contacts électriques mâles et destinés chacun à recevoir un deuxième élément support respectif en matériau électriquement isolant qui porte un contact électrique femelle, complémentaire d'un contact électrique mâle, chaque deuxième élément étant revêtu d'un blindage en forme de cage qui possède des languettes externes adaptées pour venir en contact avec des contacts de terre portés par le premier élément support. Là encore, les languettes externes et les contacts de terre associés portés par le premier élément définissent clairement un plan de joint longitudinal parallèle à la direction de translation relative des deux éléments.EP-A-0562691 discloses an electrical connector also intended for high frequencies which comprises a first support element of electrically insulating material which defines a plurality of cells receiving male electrical contacts and each intended to receive a respective second support element in electrically insulating material which carries a female electrical contact, complementary to a male electrical contact, each second element being coated with a cage-shaped shield which has external tabs adapted to come into contact with earth contacts carried by the first support element. Again, the outer tabs and the associated earth contacts carried by the first element clearly define a longitudinal joint plane parallel to the relative translation direction of the two elements.

La présente invention a maintenant pour but de perfectionner les connecteurs électriques connus pour fréquences élevées.The present invention now aims to improve the known electrical connectors for high frequencies.

Ce but est atteint selon la présente invention grâce à un connecteur du type défini en revendication 1 annexée.This object is achieved according to the present invention by means of a connector of the type defined in appended claim 1.

On a schématisé sur les figures 5, 6 et 7 annexées un élément 100 de connecteur électrique conforme à la présente invention formant prise.FIGS. 5, 6 and 7 appended show schematically an element 100 of electrical connector according to the present invention forming a socket.

Cet élément 100 comporte : un corps 110 en matériau électriquement isolant, huit lames de contact 120, 121, 122, 123, 124, 125, 126 et 127 en matériau électriquement conducteur, un blindage électromagnétique 130, quatre inserteurs 140, un serre-câble 150 et une bague de serrage 160.This element 100 comprises: a body 110 of electrically insulating material, eight contact blades 120, 121, 122, 123, 124, 125, 126 and 127 made of electrically conductive material, an electromagnetic shield 130, four inserts 140, a cable clamp 150 and a clamping ring 160.

Le corps 110 peut être formé par exemple par moulage en matière plastique électriquement isolante.The body 110 may be formed for example by molding of electrically insulating plastic material.

Le corps 110 est formé de quatre parties 110a, 110b, 110c, 110d comprenant chacune une platine arrière 111 prolongée vers l'avant par quatre poutres 112, 113, 114, 115. Les poutres 112 à 115 sont de section rectangulaire, parallèles entre elles et équidistantes deux à deux. Le rapport largeur/hauteur de la section des poutres 112-115 est typiquement de l'ordre de 3/1. La zone de liaison entre les poutres 112 à 115 et les platines arrières 111 est percée de huit canaux recevant les lames 120 à 127.The body 110 is formed of four parts 110a, 110b, 110c, 110d each comprising a rear plate 111 extended forwards by four beams 112, 113, 114, 115. The beams 112 to 115 are of rectangular section, parallel to each other and equidistant two by two. The width / height ratio of the section of the beams 112-115 is typically of the order of 3/1. The connection zone between the beams 112 to 115 and the rear plates 111 is pierced with eight channels receiving the blades 120 to 127.

Ces lames de contact 120 à 127 peuvent être réalisées en tout matériau électriquement conducteur approprié. Il s'agit de préférence de bronze élastique doré.These contact blades 120 to 127 may be made of any suitable electrically conductive material. It is preferably golden elastic bronze.

Les lames 120 à 127 s'étendent dans une direction générale parallèle à la direction d'insertion au contactage.Blades 120 to 127 extend in a general direction parallel to the contact insertion direction.

Les lames 120 à 127 sont disposées deux à deux respectivement sur les poutres 112 à 115, plus précisément, comme on le voit sur les figures 5 et 6, sur des faces parallèles en regard de celles-ci.The blades 120 to 127 are arranged in pairs respectively on the beams 112 to 115, more precisely, as can be seen in Figures 5 and 6, on parallel faces facing them.

Les lames 120 à 127 sont de préférence cambrées, convexes vers le plan médian de l'élément 100 parallèle aux faces des poutres 112 à 115 qui portent les lames 120 à 127. Comme on le voit sur la figure 5, l'extrémité avant des lames 120 à 127 peut être maintenue par une dépouille formée sur l'extrémité libre des poutres 112 à 115.The blades 120 to 127 are preferably arched, convex towards the median plane of the element 100 parallel to the faces of the beams 112 to 115 which carry the blades 120 to 127. As can be seen in FIG. blades 120 to 127 can be maintained by a flange formed on the free end of the beams 112 to 115.

L'extrémité arrière des lames 120 à 127 est pliée à 90° pour former un contact auto-dénudant accessible sur l'extérieur des platines 111 et adaptée pour coopérer avec un inserteur 140.The rear end of the blades 120 to 127 is bent at 90 ° to form a self-stripping contact accessible on the outside of the plates 111 and adapted to cooperate with an inserter 140.

Le blindage 130 formé en un matériau électriquement conducteur est de préférence moulé, par exemple en zamak. Selon le mode de réalisation illustré sur les figures annexées, le blindage 130 comprend une cage 132 de section droite rectangulaire qui entoure les poutres 112 à 115 et les lames 120 à 127. La cage 132 possède un décrochement interne 131, au voisinage des deux tiers de sa longueur.The shield 130 formed of an electrically conductive material is preferably molded, for example zamak. According to the embodiment illustrated in the accompanying figures, the shield 130 comprises a cage 132 of rectangular cross-section which surrounds the beams 112 to 115 and the blades 120 to 127. The cage 132 has an internal recess 131, in the vicinity of two-thirds of its length.

La cage 132 possède par ailleurs une excroissance 133 sur l'une de ses faces. Cette excroissance 133 est munie d'une ouverture 134 à son extrémité adjacente au décrochement 131.The cage 132 also has an excrescence 133 on one of its faces. This protrusion 133 is provided with an opening 134 at its end adjacent to the recess 131.

Le blindage 130 comporte en outre un croisillon 135 logé dans la cage 132. Le croisillon 135 est formé de deux parois 136, 137 orthogonales entre elles et jointives. Les deux parois 136, 137 sont respectivement parallèles et orthogonales aux parois de la cage 132. Les deux parois 136, 137 se raccordent sur les faces internes des parois de la cage 132. Selon le mode de réalisation donné sur les figures 5 et 6, les extrémités avant des parois 136, 137 du croisillon sont coplanaires entre elles et coplanaires du décrochement 131. Ainsi, ce mode de réalisation correspond à celui schématisé sur la figure 14.The shield 130 further comprises a spider 135 housed in the cage 132. The spider 135 is formed of two walls 136, 137 orthogonal to each other and joined. The two walls 136, 137 are respectively parallel and orthogonal to the walls of the cage 132. two walls 136, 137 are connected to the internal faces of the walls of the cage 132. According to the embodiment given in FIGS. 5 and 6, the front ends of the walls 136, 137 of the spider are coplanar with each other and coplanar with the recess 131. Thus, this embodiment corresponds to that shown diagrammatically in FIG.

Les lames 120-127 et poutres 112-115 s'étendent au-delà du croisillon 135 de préférence jusqu'à proximité immédiate du contour d'ouverture de la cage 132.The blades 120-127 and beams 112-115 extend beyond the cross-member 135 preferably to the immediate vicinity of the opening contour of the cage 132.

En outre, le croisillon 135 traverse la platine 111 et débouche sur l'extrémité arrière de celle-ci sous forme d'une aiguille 138 centrée sur le connecteur. L'aiguille 138 fait largement saillie sur l'arrière de la platine 110.In addition, the spider 135 passes through the plate 111 and opens on the rear end thereof in the form of a needle 138 centered on the connector. The needle 138 projects widely on the back of the plate 110.

Les inserteurs 140 peuvent être montés à pivotement ou à translation sur le corps 110. Ils sont adaptés, de façon connue en soi, pour forcer les lames électriquement conductrices d'un conducteur revêtu d'un isolant issu d'un câble, dans les fourchettes de contact auto-dénudant formées sur les extrémités arrières des lames de contact 120 à 127.The inserters 140 may be pivotally or translatably mounted on the body 110. They are adapted, in a manner known per se, to force the electrically conductive blades of a conductor coated with a cable insulation in the ranges self-stripping contact formed on the rear ends of the contact blades 120 to 127.

Le serre-câble 150 est réalisé de préférence en métal. Il comprend un embout avant 152 de section droite rectangulaire complémentaire de l'enveloppe externe de la cage 132 du blindage. Le serre-câble 150 comprend en outre un fût arrière cylindrique 154 fendu longitudinalement au moins sur une partie de sa longueur. Le fût 154 est fileté sur sa surface externe. La zone de liaison entre l'embout 152 et le fût 154 est effilée en direction du fût.The cable clamp 150 is preferably made of metal. It comprises a front end 152 of rectangular cross section complementary to the outer casing of the cage 132 of the shield. The cable clamp 150 further comprises a cylindrical rear shank 154 slit longitudinally over at least a part of its length. The drum 154 is threaded on its outer surface. The connection zone between the tip 152 and the barrel 154 is tapered towards the barrel.

La bague 160 est taraudée intérieurement et adaptée pour coopérer avec le filetage du fût 154 pour resserrer celui-ci sur un câble.The ring 160 is internally threaded and adapted to cooperate with the thread of the barrel 154 to tighten it on a cable.

On a représenté sur les figures 8 à 10 annexées un second élément 200 de connecteur conforme à la présente invention formant fiche.FIGS. 8 to 10 show a second connector element 200 in accordance with the present invention forming a plug.

De façon comparable à l'élément 100, l'élément 200 illustré sur les figures 8 à 10 comprend un corps 210 en matériau électriquement isolant, huit lames de contact en matériau électriquement conducteur 220, 221, 222, 223, 224, 225, 226, 227, un blindage électromagnétique 230, quatre inserteurs 240, un serre-câble 250 et une bague de serrage 260.In a manner comparable to the element 100, the element 200 illustrated in FIGS. 8 to 10 comprises a body 210 of electrically insulating material, eight contact blades of electrically conductive material 220, 221, 222, 223, 224, 225, 226 , 227, an electromagnetic shield 230, four inserters 240, a cable clamp 250 and a clamping ring 260.

Le corps 210 est formé essentiellement de quatre poutres 212, 213, 214, 215 de section droite rectangulaire (identique à celle des poutres 112-115), parallèles et équidistantes. Les lames 220 à 227 sont réalisées de préférence en bronze élastique doré. Elles s'étendent généralement parallèlement à la direction d'insertion des éléments de connecteurs 100, 200. Les lames de contact 220 à 227 sont placées respectivement deux à deux sur les faces externes des poutres 212, 213, 214 et 215. Les lames 220 à 227 sont de préférence légèrement cambrées, convexes vers l'extérieur, c'est-à-dire en éloignement du plan médian parallèle aux faces des poutres 212 à 215 qui les portent. Comme on le voit sur la figure 8, les extrémités avant des lames 220 à 227 sont de préférence maintenues dans les poutres 212 à 215.The body 210 is formed essentially of four beams 212, 213, 214, 215 of rectangular cross section (identical to that of the beams 112-115), parallel and equidistant. The blades 220 to 227 are preferably made of gilded elastic bronze. They extend generally parallel to the direction of insertion of the connector elements 100, 200. The contact strips 220 to 227 are respectively placed in pairs on the outer faces of the beams 212, 213, 214 and 215. The blades 220 at 227 are preferably slightly arched, convex outwards, that is to say away from the median plane parallel to the faces of the beams 212 to 215 which carry them. As seen in FIG. 8, the front ends of the blades 220 to 227 are preferably held in the beams 212 to 215.

Les extrémités arrières des lames 220 à 227 sont pliées à 90° pour former des contacts auto-dénudants accessibles sur l'extérieur du corps 210 et adaptés pour coopérer avec les inserteurs 240.The rear ends of the blades 220 to 227 are bent at 90 ° to form self-stripping contacts accessible on the outside of the body 210 and adapted to cooperate with the inserters 240.

Le blindage 230 est réalisé en matériau électriquement conducteur. Il est de préférence moulé, par exemple en zamak.The shield 230 is made of electrically conductive material. It is preferably molded, for example zamak.

Le blindage 230 comprend une cage 232 de section droite rectangulaire qui entoure les poutres 212 à 215 et les lames 220 à 227.The shield 230 comprises a cage 232 of rectangular cross section which surrounds the beams 212 to 215 and the blades 220 to 227.

La cage 232 est munie d'un décrochement 231 sur sa surface externe. Ce décrochement 231 est adapté pour recevoir l'extrémité libre de la cage 232 comme on le voit sur la figure 11.The cage 232 is provided with a recess 231 on its outer surface. This recess 231 is adapted to receive the free end of the cage 232 as seen in FIG. 11.

En outre, la cage 232 possède une excroissance 233 sur l'une de ses faces, homologue de l'excroissance 133 de l'élément 100. Cette excroissance 233 est adaptée pour loger un élément de verrouillage 270 qui sera décrit plus en détail par la suite.In addition, the cage 232 has a protrusion 233 on one of its faces, homologous to the protrusion 133 of the element 100. This protrusion 233 is adapted to house a locking element 270 which will be described in more detail by the after.

Par ailleurs, le blindage 230 possède un croisillon 235 logé dans la cage 232. Le croisillon 235 est formé de deux parois orthogonales entre elles et jointives 236, 237. Ces parois 236, 237 sont respectivement parallèles et orthogonales aux parois de la cage 232. Elles se raccordent sur les faces internes des parois de la cage 232.Furthermore, the shield 230 has a spider 235 housed in the cage 232. The spider 235 is formed of two orthogonal walls between them and joined 236, 237. These walls 236, 237 are respectively parallel and orthogonal to the walls of the cage 232. They are connected to the internal faces of the walls of the cage 232.

Selon le mode de réalisation illustré sur les figures 8 et 9, les extrémités avant des parois 236, 237 formant le croisillon 235 sont coplanaires entre elles et coplanaires du contour d'ouverture de la cage 232.According to the embodiment illustrated in FIGS. 8 and 9, the front ends of the walls 236, 237 forming the cross-member 235 are coplanar with each other and coplanar with the opening contour of the cage 232.

On notera que la géométrie et les dimensions des poutres 112, 113, 114 et 115 sont adaptées de sorte que celles-ci viennent se loger lors de l'assemblage entre les faces externes des poutres 212, 213, 214, 215, les faces internes de la cage 232 et la paroi verticale 237 du croisillon. De même, la cage 232 se loge lors de l'assemblage entre les faces externes des poutres 112, 113, 114, 115 et la cage 132.It will be noted that the geometry and the dimensions of the beams 112, 113, 114 and 115 are adapted so that they are housed during assembly between the external faces of the beams 212, 213, 214, 215, the internal faces of the cage 232 and the vertical wall 237 of the spider. Similarly, the cage 232 is housed during assembly between the outer faces of the beams 112, 113, 114, 115 and the cage 132.

Pour cela, les grandes faces des poutres 212, 213, 214, 215 opposées aux faces recevant les lames de contact 220 à 227, sont adjacentes à la paroi médiane horizontale 236 du croisillon 235. Par contre, les poutres 112, 113, 114, 115 sont éloignées de la paroi médiane 136 d'une distance égale à l'épaisseur ou hauteur des poutres 212-215. Les poutres 112-115 sont adjacentes par l'un de leur petit côté à la paroi 137 et de même les poutres 212-215 sont adjacentes par l'un de leur petit côté à la paroi 237.For this, the large faces of the beams 212, 213, 214, 215 opposite the faces receiving the contact blades 220 to 227, are adjacent to the horizontal medial wall 236 of the cross 235. By cons, the beams 112, 113, 114, 115 are spaced from the median wall 136 by a distance equal to the thickness or height of the beams 212-215. The beams 112-115 are adjacent by one of their short side to the wall 137 and likewise the beams 212-215 are adjacent by one of their short side to the wall 237.

Les poutres 212-215 sont adjacentes par leur second petit côté à la surface interne de parois de la cage 232 de blindage. Les autres parois de cette cage 232, orthogonales à celles précitées, sont situées à une distance de la surface externe des poutres 212-215 qui porte les lames de contact 220-227, égale à l'épaisseur des poutres 112 à 115.The beams 212-215 are adjacent by their second small side to the inner wall surface of the shielding cage 232. The other walls of this cage 232, orthogonal to those mentioned above, are located at a distance from the outer surface of the beams 212-215 which carries the contact blades 220-227, equal to the thickness of the beams 112 to 115.

L'épaisseur des parois de la cage 232 est égale à l'épaisseur de l'intervalle existant entre la surface interne de la cage 132 et les poutres 112 à 115.The thickness of the walls of the cage 232 is equal to the thickness of the gap existing between the inner surface of the cage 132 and the beams 112 to 115.

Par ailleurs, les longueurs des poutres et croisillons sont telles que après assemblage les plans d'extrémités des croisillons 135 et 235 sont adjacents.Furthermore, the lengths of the beams and braces are such that after assembly the end planes of the braces 135 and 235 are adjacent.

Pour cela la longueur séparant le décrochement 131 et l'extrémité de la cage 132 est égale à la longueur séparant le décrochement 231 et l'extrémité libre de la cage 232.For this, the length separating the recess 131 and the end of the cage 132 is equal to the length separating the recess 231 and the free end of the cage 232.

De plus, les parois 136, 137 et 236, 237 des croisillons ont respectivement même épaisseur.In addition, the walls 136, 137 and 236, 237 of the braces respectively have the same thickness.

Bien entendu, après assemblage, chacune des lames de contact 120 à 127 de l'élément 100 vient reposer contre une lame de contact 220 à 227 de l'élément 200.Of course, after assembly, each of the contact blades 120 to 127 of the element 100 rests against a contact blade 220 to 227 of the element 200.

De façon comparable à l'élément 100, le croisillon 235 se prolonge sur l'arrière du corps 210 sous forme d'une aiguille 238 centrée sur l'élément 200.In a manner comparable to the element 100, the spider 235 extends on the rear of the body 210 in the form of a needle 238 centered on the element 200.

Les inserteurs 240, serre-câble 250 et bague 260 sont respectivement similaires aux inserteurs 140, serre-câble 150 et bague 160 précités.The inserters 240, cable clamp 250 and ring 260 are respectively similar to the inserts 140, cable clamp 150 and ring 160 above.

La pièce de verrouillage 270 placée dans l'excroissance 233 est formée de préférence d'une pièce en U en matériau élastique. Cette pièce de verrouillage 270 comprend un élément de base fixe longitudinal 271 lié au blindage 230, une languette de verrouillage 272 généralement parallèle munie d'une denture 273 à son extrémité libre et une branche de liaison élastique 274. La denture 273 est adaptée pour pénétrer dans l'ouverture 134 lors de l'assemblage, par fléchissement de la zone de liaison 270. Pour démonter le connecteur, il suffit de solliciter cette zone 270 pour escamoter la denture 273.The locking piece 270 placed in the protrusion 233 is preferably formed of a U-shaped piece of elastic material. This locking piece 270 comprises a longitudinal fixed base element 271 bonded to the shield 230, a generally parallel locking tongue 272 provided with a toothing 273 at its free end and an elastic connecting branch 274. The toothing 273 is adapted to penetrate in the opening 134 during assembly, by deflection of the connecting zone 270. To remove the connector, simply solicit this area 270 to retract the toothing 273.

L'homme de l'art comprendra à l'examen des figures annexées, notamment de la figure 11 qui représente le connecteur conforme à la présente invention en position assemblée, que ce connecteur conforme à la présente invention permet de garder le blindage électromagnétique tout au long de chaque paire avec des fuites minimum. Ce connecteur permet en effet de définir quatre alvéoles matérialisés par les croisillons 135, 235 allant du plan de joint électromagnétique à l'interface jusqu'après le raccordement des fils dans les contacts auto-dénudants. Après ces contacts auto-dénudants, le câble reprend le blindage individuel de chaque paire à ras du croisillon.Those skilled in the art will understand from examination of the appended figures, in particular from FIG. 11, which represents the connector according to the present invention in the assembled position, that this connector according to the present invention makes it possible to keep the electromagnetic shield all at the same time. along each pair with minimum leaks. This connector makes it possible to define four cells materialized by the braces 135, 235 from the electromagnetic seal plane to the interface until after the connection of the wires in the insulation-removing contacts. After these self-stripping contacts, the cable takes the individual shield of each pair flush with the cross.

La présente invention permet ainsi d'optimiser le blindage en évitant toute diaphonie par fuite au niveau du plan de joint électromagnétique.The present invention thus makes it possible to optimize the shielding by avoiding any leakage crosstalk at the level of the electromagnetic sealing plane.

On a décrit précédemment des plans de joints électromagnétiques définis par des extrémités libres avant des croisillons 135, 235 coplanaires et perpendiculaires à l'axe longitudinal du connecteur. Un tel plan de joint électromagnétique droit coupe perpendiculairement l'ensemble des alvéoles comme schématisé sur la figure 14. Sur cette figure 14, ces extrémités avant des croisillons 135, 235 sont référencées 135a, 135b, 135c, 135d et 235a, 235b. En variante, on peut cependant envisager de réaliser l'extrémité avant des parois 136, 137, 236, 237 des croisillons 135, 235 sous forme de différents tronçons (135a,-d, 235a, b sur la figure 15) non coplanaires pour diminuer les risques de diaphonie. Il peut s'agir par exemple de quatre tronçons rectilignes ou plans de joints perpendiculaires à l'axe longitudinal du connecteur mais décalés dans le sens longitudinal comme illustré sur la figure 15. Les écarts longitudinaux entre les différentes tronçons formés par les extrémités avant des croisillons sont typiquement décalées d'un multiple de λ/n. Selon une autre variante schématisée sur la figure 16, les bords libres avant des parois 136, 137 et 236, 237 formant les croisillons 135, 235 sont en outre munis de crantage 139, 239. Un tel crantage 139, 239 permet d'augmenter la surface de contact entre les croisillons 135, 235 et par conséquent de diminuer l'impédance de transfert et la résistance de contact du contact de masse pour assurer une meilleure étanchéité aux fuites électromagnétiques. Bien entendu, la géométrie des extrémités avant des croisillons 135 et 235 doit être complémentaire de sorte que, malgré le décalage longitudinal et/ou le crantage, les deux croisillons soient adjacents.Previously described electromagnetic seal planes defined by free ends before braces 135, 235 coplanar and perpendicular to the longitudinal axis of the connector. Such a right electromagnetic seal plane perpendicularly intersects all the cells as shown diagrammatically in FIG. 14. In this FIG. 14, these front ends of the crosspieces 135, 235 are referenced 135a, 135b, 135c, 135d and 235a, 235b. As a variant, it is nevertheless possible to envisage making the front end of the walls 136, 137, 236, 237 of the crosspieces 135, 235 in the form of different sections (135a, -d, 235a, b in FIG. 15) that are not coplanar to reduce the risks of crosstalk. It may be for example four rectilinear sections or joint planes perpendicular to the longitudinal axis of the connector but offset in the longitudinal direction as shown in Figure 15. The longitudinal differences between the different sections formed by the front ends of the crosspieces are typically shifted by a multiple of λ / n. According to another variant shown schematically in FIG. 16, the free front edges of the walls 136, 137 and 236, 237 forming the crosspieces 135, 235 are furthermore provided with detent 139, 239. Such a detent 139, 239 makes it possible to increase the contact surface between the braces 135, 235 and therefore reduce the transfer impedance and the contact resistance of the ground contact to ensure better sealing against electromagnetic leakage. Of course, the geometry of the front ends of the braces 135 and 235 must be complementary so that, despite the longitudinal offset and / or the notch, the two braces are adjacent.

Le blindage sur l'arrière du connecteur et la reprise de masse du câble sont assurés essentiellement par les serre-câbles 150, 250 qui permettent un maintien de l'effet "tunnel" au niveau des contacts auto-dénudants en épousant extérieurement les ailettes ou les croisillons 135, 235 et grâce à une rétention mécanique du câble par rapport au blindage du connecteur réalisé par la bague de serrage filetée conique 160, 260 resserrant le serre-câble 150, 250.The shielding on the back of the connector and the grounding of the cable are essentially provided by the cable clamps 150, 250 which allow the "tunnel" effect to be maintained at the level of the self-stripping contacts by conforming externally to the fins or the braces 135, 235 and thanks to a mechanical retention of the cable relative to the shielding of the connector made by the conical threaded clamping ring 160, 260 tightening the cable clamp 150, 250.

Les aiguilles 138, 238 disposées à l'arrière du blindage, au centre des croisillons, permettent d'assurer un contact avec les blindages individuels des paires de conducteurs.The needles 138, 238 disposed at the rear of the shield at the center of the braces, allow to ensure contact with the individual shields of the pairs of conductors.

Comme on l'a schématisé sur les figures 12 et 13, pour améliorer le contact entre le blindage formé par les serre-câbles 150, 250 et les bagues 160, 260, ces dernières peuvent être munies sur leur surface interne d'un racleur élastique 162. Sur la figure 12, on a schématisé un câble C sur l'extrémité avant duquel on a retourné la tresse de masse T, ainsi qu'un serre-câble 150 et une bague de serrage 160 munie d'un racleur élastique 162.As shown schematically in Figures 12 and 13, to improve the contact between the shield formed by the clamps 150, 250 and the rings 160, 260, the latter can be provided on their inner surface with an elastic scraper 162. In FIG. 12, a cable C has been schematized on the front end of which the ground braid T has been turned over, as well as a cable clamp 150 and a clamping ring 160 provided with an elastic scraper 162.

Par ailleurs, on a représenté sur la figure 13 le même ensemble après engagement de la bague de serrage 160 sur le serre-câble 150. On note que la tresse T est serrée entre le racleur élastique 162 et le serre-câble 150.Moreover, FIG. 13 shows the same assembly after engagement of the clamping ring 160 with the cable clamp 150. It is noted that the braid T is clamped between the elastic scraper 162 and the cable clamp 150.

La prise 100 illustrée sur les figures 5 à 7 annexées peut être montée indifféremment dans des supports de plinthe ou muraux au niveau des points d'accès, mais aussi dans les panneaux de brassage au niveau des répartiteurs. Une telle prise 100 peut notamment être montée dans un boîtier équipé d'un plastron à capot basculant permettant la fermeture du boîtier en l'absence de fiche.The socket 100 illustrated in Figures 5 to 7 attached can be mounted indifferently in skirting or wall brackets at the access points, but also in the patch panels at the splitter. Such a socket 100 may in particular be mounted in a housing equipped with a flap cover bonnet for closing the housing in the absence of plug.

Pour relier un câble à l'un des éléments de connecteurs 100, 200 conformes à la présente invention, on procède typiquement par la séquence d'étapes qui consiste à :

  • placer la bague de serrage 160, 260 en attente sur un câble,
  • dénuder la gaine extérieure du câble sur environ 25-mm,
  • retrousser la tresse T du câble vers l'arrière sur la gaine extérieure de celui-ci,
  • dénuder l'écran individuel des paires de conducteur sur environ 10 mm,
  • ramener tous les conducteurs soigneusement dans l'axe du câble et retourner le drain en arrière sur la tresse T,
  • glisser le serre-câble 150, 250 sur la tresse T en prenant soin que le drain soit opposé à la fente du serre-câble,
  • introduire les paires de conducteur dans l'ordre dans les inserteurs 140, 240,
  • rabattre ces inserteurs 140, 240 jusqu'au clipsage et ramener les conducteurs dans l'axe du câble de sorte que les blindages individuels des conducteurs entourent l'aiguille 138, 238 du blindage,
  • ramener le serre-câble 150, 250 en position sur le connecteur en rabattant un maximum de tresse et de drain à l'intérieur, et
  • visser la bague de serrage 160, 260 jusqu'au blocage efficace du câble.
To connect a cable to one of the connector elements 100, 200 in accordance with the present invention, the sequence of steps that consists of:
  • place the clamping ring 160, 260 on a cable,
  • strip the outer sheath of the cable about 25-mm,
  • roll up the braid T of the cable backwards on the outer sheath of the latter,
  • strip the individual screen of the pairs of conductors about 10 mm,
  • bring all the conductors carefully in the cable axis and turn the drain back on the T braid,
  • slide the cable clamp 150, 250 onto the braid T, taking care that the drain is opposite to the slot of the cable tie,
  • introduce the pairs of conductors in order in the inserters 140, 240,
  • fold these inserters 140, 240 until clipping and return the conductors in the axis of the cable so that the individual shields of the conductors surround the needle 138, 238 of the shield,
  • bring the cable clamp 150, 250 into position on the connector by folding a maximum of braid and drain inside, and
  • tighten the clamping ring 160, 260 until the cable is effectively locked.

Bien entendu, on peut également utiliser plusieurs ensembles de connecteurs conformes à la présente invention en position juxtaposée, notamment dans une plinthe.Of course, it is also possible to use several sets of connectors according to the present invention in juxtaposed position, in particular in a plinth.

L'homme de l'art appréciera que la présente invention permet un raccordement facile et rapide sur site.Those skilled in the art will appreciate that the present invention allows for easy and quick field connection.

On a illustré sur les figures 17 et 18 annexées une variante de réalisation d'un élément 1000 de connecteur hermaphrodite conforme à la présente invention.FIGS. 17 and 18 show an alternative embodiment of a hermaphrodite connector element 1000 according to the present invention.

On distingue sur ces figures 17 et 18 un élément 1000 de connecteur qui comprend principalement :

  • un blindage 1300 électriquement conducteur,
  • des corps 1100, 1110, 1120, 1130, 1140, 1150, 1160 et 1170 en matériau électriquement isolant, qui porte
  • des paires de contact 1200, 1210, 1220, 1230, 1240, 1250, 1260 et 1270, et
  • des inserteurs 1400, 1410, 1420 et 1430.
These figures 17 and 18 distinguish a connector element 1000 which mainly comprises:
  • an electrically conductive shield 1300,
  • bodies 1100, 1110, 1120, 1130, 1140, 1150, 1160 and 1170 of electrically insulating material, which carries
  • contact pairs 1200, 1210, 1220, 1230, 1240, 1250, 1260 and 1270, and
  • inserters 1400, 1410, 1420 and 1430.

Le blindage 1300 peut être réalisé de tous moyens appropriés, par exemple par métallisation d'un boitier en matière plastique ou encore par moulage d'un matériau électriquement conducteur, par exemple en zamak.The shield 1300 may be made of any suitable means, for example by metallization of a plastic case or by molding an electrically conductive material, for example zamak.

Le blindage 1300 comporte une partie 1310, centrale, en forme de « 8 » définissant quatre alvéoles de sections rectangulaires identiques, destinés à recevoir respectivement l'un des corps 1100, 1110, 1120 et 1130 de section complémentaire portant chacun une paire de contacts.The shielding 1300 comprises a central portion 1310, in the form of a "8" defining four cells of identical rectangular sections, intended to respectively receive one of the bodies 1100, 1110, 1120 and 1130 of complementary section each carrying a pair of contacts.

Cette partie centrale 1310 est prolongée vers l'arrière par des toiles longitudinales 1320 formant un double « E » inversé possédant une âme commune. Ces toiles 1320 sont placées dans le prolongement des parois de la partie centrale 1310. Elles définissent ainsi quatre logements ouverts latéralement vers l'extérieur du connecteur, destinés à recevoir les corps complémentaires 1140, 1150, 1160 et 1170 support des contacts ainsi que les inserteurs 1400, 1410, 1420 et 1430.This central portion 1310 is extended rearwardly by longitudinal webs 1320 forming an inverted double "E" having a common core. These paintings 1320 are placed in the extension of the walls of the central portion 1310. They thus define four open housing laterally to the outside of the connector, intended to receive the complementary bodies 1140, 1150, 1160 and 1170 support contacts and the inserters 1400, 1410, 1420 and 1430.

L'ouverture latérale des logements définis par les toiles 1320 est destinée à permettre le déplacement des inserteurs 1400, 1410, 1420 et 1430 nécessaire pour engager les conducteurs sur les contacts 1210 à 1270.The lateral opening of the housings defined by the cloths 1320 is intended to allow the movement of the inserters 1400, 1410, 1420 and 1430 necessary to engage the conductors on the contacts 1210 to 1270.

Par ailleurs la partie centrale 1310 du blindage est prolongée vers l'avant par des cloisonnements 1330 adaptés pour s'interpénétrer avec des cloisonnements identiques d'un élément de connecteur complémentaire hermaphrodite.Furthermore the central portion 1310 of the shield is extended forward by partitions 1330 adapted to interpenetrate with identical partitions of a complementary hermaphrodite connector element.

Selon le mode de réalisation particulier et non limitatif illustré sur les figures 17 et 18, ces cloisonnements 1330 comprennent une cloison 1332 en « E », deux cloisons 1334 et 1335 en « U » et deux barrettes 1336, 1337.According to the particular and non-limiting embodiment illustrated in FIGS. 17 and 18, these partitions 1330 comprise a partition 1332 at "E", two partitions 1334 and 1335 at "U" and two bars 1336, 1337.

La cloison 1332 en « E » est ouverte vers un plan médian longitudinal du connecteur. Elle définit ainsi deux alvéoles destinés à recevoir respectivement une paire de broches mâles 1240, 1250 et 1260, 1270. La surface externe de cette cloison 1332 prolonge la surface externe de trois des parois de la partie centrale 1310. Cependant la cloison 1332 possède une épaisseur inférieure à l'épaisseur des parois composant la partie centrale 1310 en « 8 ». Ainsi il est défini, au niveau de la zone de raccordement de la cloison 1332 sur la partie centrale 1310, au fond des alvéoles formés par cette cloison 1332, un décrochement 1331, visible sur la figure 18, dirigé vers l'avant du connecteur, interne aux alvéoles précités et transversal à la direction d'engagement des éléments de connecteur.Partition 1332 at "E" is open towards a longitudinal median plane of the connector. It thus defines two cells for respectively receiving a pair of male pins 1240, 1250 and 1260, 1270. The outer surface of this partition 1332 extends the outer surface of three of the walls of the central portion 1310. However, the partition 1332 has a thickness less than the thickness of the walls forming the central portion 1310 at "8". Thus, at the level of the connection zone of the partition 1332 on the central portion 1310, at the bottom of the cells formed by this partition 1332, a recess 1331, visible in FIG. 18, directed towards the front of the connector, is defined, internal to the aforementioned cells and transverse to the direction of engagement of the connector elements.

Les cloisons 1334 et 1335 en « U » ont leurs âmes adjacentes au plan médian longitudinal précité, en regard des ouvertures de la cloison 1332 en « E ». Elles ont ainsi leur « U » dirigé vers l'extérieur du connecteur à l'opposée de l'âme de la cloison 1332. Les barrettes 1336 et 1337 sont quant à elles disposées au niveau de l'ouverture de ces cloisons 1334 et 1335 en « U ». Les cloisons 1334 et 1335 en « U » définissent ainsi en combinaison avec les barrettes 1336 et 1337, deux alvéoles destinés à recevoir respectivement l'un des supports 1100, 1110 portant chacun une paire de fiches femelles 1210, 1220 et 1230, 1240. Les cloisons 1334 et 1335 en « U » et les barrettes 1336 et 1337 possèdent une épaisseur inférieure à l'épaisseur des parois composant la partie centrale 1310 en « 8 ». Ainsi il est défini, au niveau de la zone de raccordement des cloisons 1334 et 1335 en « U » et des barrettes 1336 et 1337 sur la partie centrale 1310, au fond des alvéoles formés par ces cloisons 1334 et 1335 en « U » et cesbarrettes 1336 et 1337, un décrochement 1338, visible sur la figure 18, dirigé vers l'avant du connecteur, externe aux alvéoles précités et transversal à la direction d'engagement des éléments de connecteur.The partitions 1334 and 1335 in "U" have their souls adjacent to the aforementioned longitudinal median plane, facing the openings of the partition 1332 in "E". They have their "U" directed towards the outside of the connector opposite the soul of the partition 1332. The bars 1336 and 1337 are arranged at the opening of these partitions 1334 and 1335. "U". The walls 1334 and 1335 in "U" thus define in combination with the bars 1336 and 1337, two cells intended for respectively receiving one of the supports 1100, 1110 each carrying a pair of sockets 1210, 1220 and 1230, 1240. The partitions 1334 and 1335 "U" and the bars 1336 and 1337 have a thickness less than the thickness of the walls component central portion 1310 at "8". Thus it is defined, at the level of the connection area of the partitions 1334 and 1335 in "U" and bars 1336 and 1337 on the central portion 1310, the bottom of the cells formed by these partitions 1334 and 1335 in "U" and cesbarrettes 1336 and 1337, a recess 1338, visible in Figure 18, directed towards the front of the connector, external to the aforementioned cells and transverse to the direction of engagement of the connector elements.

L'utilisation de barrettes 1336, 1337 indépendantes des cloisons 1334, 1335 permet de disposer d'un élément élastique propre à établir un bon contact électrique avec l'élément de blindage (cloison 1332) de l'élément de connecteur complémentaire. A cette fin le cas échéant les barrettes 1336, 1337 peuvent être munies d'une protubérance adaptée pour venir reposer sur ledit élément de blindage (cloison 1332) de l'élément de connecteur complémentaire.The use of strips 1336, 1337 independent partitions 1334, 1335 provides a resilient element adapted to establish a good electrical contact with the shielding element (partition 1332) of the complementary connector element. For this purpose, if necessary, the bars 1336, 1337 may be provided with a protuberance adapted to rest on said shielding element (partition 1332) of the complementary connector element.

La section droite des structures définies par les cloisons 1334, 1335 en « U » et les barrettes 1336 et 1337 est complémentaire de la section droite des alvéoles définis par la cloison 1332. Et la largeur du décrochement 1331 est identique à l'épaisseur des cloisons 1334, 1335 et des barrettes 1336 et 1337, tandis que la largeur du décrochement 1338 est identique à l'épaisseur de la cloison 1332. Ainsi l'homme de l'art comprendra que le blindage 1300 définit un élément hermaphrodite de connecteur autorisant l'insertion des structures définies par les cloisons 1334, 1335 en « U » et les barrettes 1336 et 1337 dans les alvéoles définis par la cloison 1332 d'un élément de connecteur complémentaire.The cross-section of the structures defined by the partitions 1334, 1335 in "U" and the bars 1336 and 1337 is complementary to the cross-section of the cells defined by the partition 1332. And the width of the step 1331 is identical to the thickness of the partitions. 1334, 1335 and bars 1336 and 1337, while the width of the recess 1338 is identical to the thickness of the partition 1332. Thus, one skilled in the art will understand that the shield 1300 defines a hermaphroditic element of connector allowing the insertion of the structures defined by the partitions 1334, 1335 in "U" and the bars 1336 and 1337 in the cells defined by the partition 1332 of a complementary connector element.

Une fois ces éléments de connecteurs engagés, le plan de joint électromagnétique transversal à la direction d'engagement des éléments de connecteurs est défini par le plan de contact entre les décrochements 1331, 1338 et le sommet des cloisons 1332, 1334, 1335 et des barrettes 1336 et 1337 placées en regard.Once these connector elements engaged, the electromagnetic sealing plane transverse to the engagement direction of the connector elements is defined by the contact plane between the recesses 1331, 1338 and the top of the partitions 1332, 1334, 1335 and bars 1336 and 1337 placed opposite.

Pour permettre un détrompage, la cloison 1332 est de plus munie sur la surface externe de l'une de ses ailes latérales, d'une protubérance 1302., par exemple parallélépipèdique, qui affleure le plan médian longitudinal précité. Après assemblage les deux protubérances 1302 des éléments de connecteur sont adjacentes.To allow keying, the partition 1332 is further provided on the outer surface of one of its lateral wings, a protuberance 1302., for example parallelepiped, which is flush with the aforementioned longitudinal median plane. After assembly the two protuberances 1302 of the connector elements are adjacent.

On notera également que le blindage 1300 est de préférence muni sur sa surface externe de dentures en saillie 1304 conçues pour immobiliser par encliquetage des coquilles de boitier 1800, 1810 schématisées sur la figure 17.It will also be noted that the shielding 1300 is preferably provided on its external surface with protruding toothing 1304 designed to snap-fasten case shells 1800, 1810 shown diagrammatically in FIG.

Les corps support en matériau électriquement isolant 1100 et 1110 sont constitués essentiellement de blocs parallélépipèdiques de section droite complémentaire de la section des alvéoles définis par les cloisons 1334, 1335 et les barrettes 1336 et 1337, ainsi que les alvéoles définis par la partie centrale 1310. Ils s'étendent sur la longueur de la partie centrale 1310 et des alvéoles précités définis par les cloisons 1334, 1335 et les barrettes 1336 et 1337. Ces corps 1100 et 1110 sont munis chacun de deux canaux longitudinaux recevant chacun une fiche femelle 1200, 1210, 1220 et 1230.The support bodies of electrically insulating material 1100 and 1110 consist essentially of parallelepipedic blocks of cross-section complementary to the section of the cells defined by the partitions 1334, 1335 and the bars 1336 and 1337, as well as the cells defined by the central portion 1310. They extend along the length of the central portion 1310 and the aforementioned cells defined by the partitions 1334, 1335 and the bars 1336 and 1337. These bodies 1100 and 1110 are each provided with two longitudinal channels each receiving a female plug 1200, 1210 , 1220 and 1230.

Les corps support en matériau électriquement isolant 1120 et 1130 sont constitués essentiellement de blocs parallélépipèdiques de section droite complémentaire de la section des alvéoles définis par la partie centrale 1310. Ils s'étendent sur la longueur de cette partie centrale 1310. Ces corps 1120 et 1130 sont munis chacun de deux canaux longitudinaux recevant chacun une broche mâle 1240, 1250, 1260 et 1270.The support bodies of electrically insulating material 1120 and 1130 consist essentially of parallelepipedic blocks of cross section complementary to the section of the cells defined by the central portion 1310. They extend along the length of this central portion 1310. These bodies 1120 and 1130 are each provided with two longitudinal channels each receiving a male pin 1240, 1250, 1260 and 1270.

Les corps support 1140, 1150, 1160 et 1170 prolongent respectivement les corps support 1100, 1110, 1120 et 1130. Ils possèdent chacun deux canaux ouverts latéralement vers l'extérieur du connecteur pour recevoir une paire de contacts 1200 à 1270 et permettre l'engagement des conducteurs sur ces contacts grâce aux inserteurs 1400 à 1430 respectivement.The support bodies 1140, 1150, 1160 and 1170 respectively extend the support bodies 1100, 1110, 1120 and 1130. They each have two open channels laterally outwardly of the connector to receive a pair of contacts 1200 to 1270 and enable the engagement. conductors on these contacts through the inserters 1400 to 1430 respectively.

A cette fin chaque contact 1200 à 1270 est muni sur son extrémité arrière accessible au niveau des canaux des corps supports 1140 à 1170 d'une fourchette de contact autodénudantes, comme on le voit sur la figure 17.For this purpose each contact 1200 to 1270 is provided on its rear end accessible at the level of the channels of the support bodies 1140 to 1170 of a self-cutting contact fork, as seen in FIG. 17.

Le cas échéant les corps supports 1140, 1150, 1160 et 1170 pourraient être formés d'une pièce respectivement avec les corps supports 1100, 1110, 1120 et 1130.Where appropriate the support bodies 1140, 1150, 1160 and 1170 could be formed of a part respectively with the support bodies 1100, 1110, 1120 and 1130.

Ainsi par exemple dans le cadre de la variante de réalisation illustré sur les figures 17 et 18, on peut prévoir d'inverser la disposition des fiches femelles 1200-1230 et des broches mâles 1240-1270, en disposant les broches mâles 1240-1270 dans les alvéoles définis par les cloisons 1334, 1335 et barrettes 1336, 1337 et en disposant les fiches femelles 1200-1230 dans les alvéoles définis par la cloison 1332.Thus, for example, in the context of the embodiment variant illustrated in FIGS. 17 and 18, it is possible to invert the arrangement of the female sockets 1200-1230 and the male pins 1240-1270, by arranging the male pins 1240-1270 in the cells defined by the partitions 1334, 1335 and bars 1336, 1337 and arranging the female sockets 1200-1230 in the cells defined by the partition 1332.
