Description

L'invention se rapporte à un connecteur électrique pour haut débit, par exemple permettant de permettre la transmission de signaux "ethernet" de l'ordre de 10 Gigabits par seconde. Elle concerne plus particulièrement un perfectionnement visant une meilleure conservation de l'impédance caractéristique d'une paire torsadée de conducteurs électriques isolés.The invention relates to an electrical connector for broadband, for example to allow the transmission of "ethernet" signals of the order of 10 Gigabits per second. It relates more particularly to an improvement aiming at a better conservation of the characteristic impedance of a twisted pair of insulated electrical conductors.

On connaît un connecteur blindé pour haut débit comprenant au moins une paire d'éléments de connexion, de type mâle ou femelle, lesdits éléments de connexion étant parallèles et installés dans une cavité à section oblongue à paroi métallique formant blindage. La cavité abrite un insert en matériau isolant, à haute caractéristique diélectrique, formant le support desdits éléments de connexion.There is known a high-speed shielded connector comprising at least one pair of connection elements, of the male or female type, said connecting elements being parallel and installed in an oblong section cavity with a metal wall forming a shield. The cavity houses an insulating material insert, with a high dielectric characteristic, forming the support of said connection elements.

Un tel connecteur, s'il s'agit d'une fiche, est destiné à être relié à un câble de transmission de données comprenant au moins une paire de conducteurs torsadés entre eux. Les conducteurs sont entourés d'un blindage métallique. Deux connecteurs semblables peuvent être montés aux extrémités d'un câble comportant au moins une telle paire de conducteurs. Le connecteur peut aussi être conformé en embase, propre à être montée sur un support d'un appareil électronique (la paroi du boîtier de cet appareil, par exemple) afin de recevoir un connecteur formant fiche, du même type.Such a connector, if it is a plug, is intended to be connected to a data transmission cable comprising at least one pair of conductors twisted together. The conductors are surrounded by a metal shield. Two similar connectors may be mounted at the ends of a cable having at least one such pair of conductors. The connector may also be dished, adapted to be mounted on a support of an electronic device (the housing wall of this device, for example) to receive a plug connector of the same type.

Dans ce type de connecteur, il est courant de disposer de quatre paires d'éléments de connexion raccordés à quatre paires de conducteurs. Chaque paire est entourée d'un blindage électromagnétique métallique. Une ligne équipée de tels connecteurs comporte donc quatre canaux de transmission d'informations à haut débit. Un blindage extérieur global, tant du connecteur que du câble, protège la ou les lignes des perturbations électromagnétiques extérieures tandis que les blindages particuliers des paires de conducteurs torsadés réduit la diaphonie entre les canaux. Le brevet américain 7 316 584 décrit un connecteur de ce genre. D'autres exemples de connecteurs ont été décrits dans les brevets américain 5 342 221, 4 455 056 et 7 402 077, ainsi que dans la publication de demande de brevet américain US 2004/018759 .In this type of connector, it is common to have four pairs of connection elements connected to four pairs of conductors. Each pair is surrounded by a metallic electromagnetic shield. A line equipped with such connectors therefore comprises four high-speed information transmission channels. An overall outer shielding of both the connector and the cable protects the line (s) from external electromagnetic interference while the particular shields of the twisted pair of conductors reduce crosstalk between the channels. US Pat. No. 7,316,584 discloses a connector of this kind. Other examples of connectors have been described in US Patents 5,342,221, 4,455,056 and 7,402,077, as well as in the US patent application publication. US 2004/018759 .

Pour augmenter encore les performances de ces équipements, il est souhaitable de veiller à une bonne conservation de l'impédance caractéristique de la ligne de transmission, notamment à l'intersection entre deux connecteurs raccordés bout à bout. En effet, une bonne conservation de l'impédance caractéristique tout le long du câblage permet d'optimiser le transfert de puissance entre un émetteur et un récepteur. En particulier, l'impédance du récepteur doit être égale à l'impédance caractéristique de la ligne, pour éviter les réflexions. Une désadaptation d'impédance locale peut être à l'origine de l'apparition de phénomènes d'ondes stationnaires générant des pertes de transmission.To further increase the performance of these equipment, it is desirable to ensure good preservation of the characteristic impedance of the transmission line, particularly at the intersection between two connectors connected end to end. Indeed, a good preservation of the characteristic impedance all along the wiring makes it possible to optimize the transfer of power between a transmitter and a receiver. In particular, the impedance of receiver must be equal to the characteristic impedance of the line, to avoid reflections. Local impedance mismatch can cause the appearance of standing wave phenomena generating transmission losses.

L'invention permet de résoudre ce problème.The invention solves this problem.

Plus particulièrement, l'invention concerne un connecteur haut débit comprenant au moins une paire torsadée de conducteurs électriques, une paire d'éléments de connexion, de type mâle ou femelle, parallèles installés dans un insert en matériau isolant formant le support desdits éléments de connexion, chacun desdits éléments de connexion de ladite paire d'éléments de connexion étant électriquement connecté à un conducteur électrique de la paire torsadée, et dans lequel la portion extrême dudit insert est conformée pour définir, entre les deux éléments de connexion, une chicane. Plus spécifiquement, dans le connecteur de l'invention, cette chicane est apte à conférer un contact diélectrique à l'interface d'aboutement entre ledit insert et un autre insert semblable appartenant à un autre connecteur, établissant une continuité du diélectrique à ladite interface d'aboutement.More particularly, the invention relates to a high-speed connector comprising at least one twisted pair of electrical conductors, a pair of parallel male or female connection elements installed in an insert of insulating material forming the support of said connection elements. each of said connecting elements of said pair of connection elements being electrically connected to an electrical conductor of the twisted pair, and wherein the end portion of said insert is shaped to define, between the two connection elements, a baffle. More specifically, in the connector of the invention, this baffle is able to impart a dielectric contact to the abutment interface between said insert and another similar insert belonging to another connector, establishing a continuity of the dielectric at said interface. butting.

L'insert peut notamment être installé dans une cavité à paroi métallique, formant blindage électromagnétique. Ladite paire torsadée peut aussi être recouverte d'une gaine métallique souple formant blindage électromagnétique. Ainsi, il est possible d'assurer une continuité du blindage électromagnétique autour de la paire d'éléments de connexion et au-delà.The insert may in particular be installed in a cavity with a metal wall, forming an electromagnetic shielding. Said twisted pair may also be covered with a flexible metallic sheath forming electromagnetic shielding. Thus, it is possible to ensure continuity of the electromagnetic shielding around the pair of connection elements and beyond.

Selon un exemple, le connecteur est caractérisé en ce que l'extrémité dudit insert comprend une dent faisant saillie suivant une direction parallèle à celle desdits éléments de connexion et une échancrure adjacente parallèle débouchant au pied de ladite dent, la dent et l'échancrure étant de forme et dimensions sensiblement identiques pour coopérer avec une échancrure et une dent semblables, respectivement, dudit autre insert.According to one example, the connector is characterized in that the end of said insert comprises a tooth projecting in a direction parallel to that of said connecting elements and an adjacent parallel notch opening at the foot of said tooth, the tooth and the notch being of substantially identical shape and dimensions to cooperate with a notch and a similar tooth, respectively, of said other insert.

Ainsi, l'adaptation d'impédance est conservée à la connexion entre les éléments de connexion mâle et femelle appartenant aux deux connecteurs, par le fait qu'il n'y a plus de rupture brutale des caractéristiques d'isolation à l'interface. En particulier, la lame d'air subsistant, dans les dispositifs de la technique antérieure, entre les extrémités des deux inserts est supprimée par le contact de ceux-ci au niveau de la chicane.Thus, the impedance matching is maintained at the connection between the male and female connection elements belonging to the two connectors, in that there is no longer a sudden rupture of the insulation characteristics at the interface. In particular, the air gap remaining in the devices of the prior art between the ends of the two inserts is removed by the contact thereof at the baffle.

Autrement dit, les deux inserts sont en contact et s'interpénètrent sur une certaine longueur, ce qui limite les variations d'impédance dans la zone de raccordement.In other words, the two inserts are in contact and interpenetrate over a certain length, which limits the variations of impedance in the connection zone.

L'invention sera mieux comprise et d'autres caractéristiques de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre d'un mode de réalisation d'un connecteur conforme à son principe, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés, dans lesquels :

  • la figure 1 est une vue partielle en perspective de l'extrémité d'un connecteur conforme à l'invention ;
  • la figure 2 est une vue de détail à plus grande échelle d'un insert formant le support de deux éléments de connexion ;
  • la figure 3 est une vue à plus grande échelle de l'extrémité de l'insert ; et
  • les figures 4 à 6 sont des vues schématiques partielles en coupe longitudinale, illustrant la coopération de deux inserts appartenant à deux connecteurs complémentaires semblables, respectivement équipés d'éléments de connexion mâle et femelle.
The invention will be better understood and other features thereof will appear more clearly in the light of the following description of a mode of embodiment of a connector according to its principle, given solely by way of example and with reference to the appended drawings, in which:
  • the figure 1 is a partial perspective view of the end of a connector according to the invention;
  • the figure 2 is a detail view on a larger scale of an insert forming the support of two connecting elements;
  • the figure 3 is a view on a larger scale of the end of the insert; and
  • the Figures 4 to 6 are partial schematic views in longitudinal section, illustrating the cooperation of two inserts belonging to two similar complementary connectors, respectively equipped with male and female connection elements.

Sur la figure 1, on distingue la face frontale 11 d'un connecteur haut débit 13, ici une partie d'un socle, portant des éléments de connexion de type femelle. D'autres éléments du connecteur, classiques, n'ont pas été représentés, comme par exemple ceux qui font partie d'un blindage externe entourant le sous-ensemble représenté. La figure 1 montre un corps 17 où sont définies, selon l'exemple, quatre cavités 19 s'étendant longitudinalement. Chaque cavité a ici une section oblongue et abrite une paire d'éléments de connexion 15, ici du type femelle. Les parois de ces cavités sont au moins métallisées pour assurer le blindage électromagnétique des éléments de connexion qu'elles renferment. Dans l'exemple, le corps 17 dans son entier, est métallique. L'invention s'applique quel que soit le nombre de cavités. Dans l'exemple, l'agencement est classique avec les quatre cavités 19 régulièrement espacées circonférentiellement dans le corps 17 globalement cylindrique. Chaque cavité 19 est prolongée, au-delà d'une surface de base 21 à contour circulaire du corps 17, par une jupe de blindage 23 apte à entrer en contact avec une jupe de blindage 23a semblable mais plus grande d'un autre connecteur 13a (voir figure 4) pour assurer la continuité du blindage électromagnétique avec cet autre connecteur, lequel est pourvu d'autres éléments de connexion 15a, de type mâle selon l'exemple. La jupe de blindage 23a coulisse à l'extérieur de la jupe de blindage 23 du connecteur 13 portant les éléments de connexion 15 de type femelle.On the figure 1 , there is the front face 11 of a high-speed connector 13, here a part of a base, carrying connection elements of the female type. Other elements of the connector, conventional, have not been shown, such as those part of an outer shield surrounding the subset shown. The figure 1 shows a body 17 where are defined, according to the example, four cavities 19 extending longitudinally. Each cavity here has an oblong section and houses a pair of connection elements 15, here of the female type. The walls of these cavities are at least metallized to electromagnetic shield the connection elements they contain. In the example, the body 17 in its entirety is metallic. The invention applies regardless of the number of cavities. In the example, the arrangement is conventional with the four cavities 19 regularly spaced circumferentially in the generally cylindrical body 17. Each cavity 19 is extended, beyond a base surface 21 with a circular contour of the body 17, by a shielding skirt 23 able to come into contact with a similar but larger shielding skirt 23a of another connector 13a. (see figure 4 ) to ensure the continuity of the electromagnetic shielding with this other connector, which is provided with other connection elements 15a, male type according to the example. The shielding skirt 23a slides outside the shielding skirt 23 of the connector 13 carrying the female-type connection elements 15.

Chaque cavité 19 abrite un insert 25 en matériau isolant. Les caractéristiques du matériau isolant sont prédéterminées en fonction de l'impédance caractéristique à conserver. L'insert 25 forme le support de deux éléments de connexion 15. Sur les figures 1 et 2, on voit que chaque élément de connexion de type femelle est logé dans un conduit 27 de l'insert. L'agencement est semblable pour des éléments de connexion de type mâle. Les deux conduits sont parallèles et par conséquent les deux éléments de connexion sont parallèles et espacés d'une distance prédéterminée. Chaque élément de connexion, ici de type femelle, comporte une portion tubulaire dont l'extrémité ouverte se situe au voisinage d'un orifice du conduit 27 correspondant de l'insert 25.Each cavity 19 houses an insert 25 of insulating material. The characteristics of the insulating material are predetermined according to the characteristic impedance to be retained. The insert 25 forms the support of two connection elements 15. On the Figures 1 and 2 it can be seen that each female-type connection element is housed in a conduit 27 of the insert. The arrangement is similar for male type connection elements. The two ducts are parallel and therefore the two connecting elements are parallel and spaced a predetermined distance. Each connection element, here of the female type, comprises a tubular portion whose open end is situated in the vicinity of an orifice of the corresponding conduit 27 of the insert 25.

A l'autre extrémité de l'insert 25, deux conducteurs isolés 31 sont électriquement connectés aux deux éléments de connexion 15, respectivement. Ils sont torsadés entre eux au-delà des conduits 27 de l'insert et l'ensemble de chaque paire de conducteurs torsadés est recouvert d'une gaine métallique souple 35 formant un blindage réduisant la diaphonie avec les autres paires de conducteurs reliées au même connecteur.At the other end of the insert 25, two insulated conductors 31 are electrically connected to the two connection elements 15, respectively. They are twisted together beyond the conduits 27 of the insert and the assembly of each pair of twisted conductors is covered with a flexible metal sheath 35 forming a shield reducing crosstalk with the other pairs of conductors connected to the same connector .

Sur la figure 4, on retrouve le même insert 25 équipé des deux éléments de connexion 15 de type femelle et appartenant au même connecteur 13. Un autre insert 25a semblable renfermant des éléments de connexion 15a de type mâle, en forme de broche, est aussi visible sur la figure 3. Les broches s'engagent dans les éléments de connexion 15 de type femelle. Comme indiqué, cet autre insert 25a est installé dans un autre corps métallique 17a appartenant à un autre connecteur 13a conforme à l'invention. La jupe de blindage 23a de la cavité de cet insert 25a est visible sur la figure 4 et sa surface interne est en contact coulissant avec la surface externe de la jupe de blindage 23 correspondante, appartenant au connecteur 13.On the figure 4 the same insert 25 provided with the two female-type connecting elements 15 and belonging to the same connector 13 is included. Another similar insert 25a enclosing male pin-shaped connection elements 15a is also visible on the figure 3 . The pins engage in the female type connection elements. As indicated, this other insert 25a is installed in another metal body 17a belonging to another connector 13a according to the invention. The shielding skirt 23a of the cavity of this insert 25a is visible on the figure 4 and its inner surface is in sliding contact with the outer surface of the corresponding shielding skirt 23 belonging to the connector 13.

Selon une caractéristique importante de l'invention, la portion extrême de l'insert 25 est conformée pour définir une chicane 37 conférant un contact diélectrique à l'interface d'aboutement entre ledit insert 25 et un autre insert semblable 25a appartenant à un autre connecteur 13a, comme illustré sur les figures 5 et 6. La chicane 37 se situe entre les deux éléments de connexion 15. Ainsi une continuité du diélectrique est conservée à cette interface d'aboutement, notamment par le fait que les parois des deux inserts définissant la chicane sont en contact mécanique effectif, de préférence sur au moins la plus grande partie de leurs surfaces.According to an important feature of the invention, the end portion of the insert 25 is shaped to define a baffle 37 imparting a dielectric contact to the abutment interface between said insert 25 and another similar insert 25a belonging to another connector 13a, as illustrated in Figures 5 and 6 . The baffle 37 is located between the two connection elements 15. Thus a continuity of the dielectric is maintained at this abutment interface, in particular by the fact that the walls of the two inserts defining the baffle are in effective mechanical contact, preferably on the minus most of their surfaces.

Selon l'exemple représenté, l'extrémité dudit insert comprend, entre les deux éléments de connexion, une dent 39 faisant saillie suivant une direction parallèle à celle desdits éléments de connexion et une échancrure 41 adjacente, parallèle, débouchant au pied de ladite dent. La dent 39 et l'échancrure 41 sont de forme et dimensions sensiblement identiques pour coopérer avec une échancrure 41a et une dent 39a semblables, respectivement, d'un autre insert 25a appartenant à l'autre connecteur 13a et renfermant la paire d'éléments de connexion 15a de type mâle, comme cela est visible sur la figure 4.According to the example shown, the end of said insert comprises, between the two connection elements, a tooth 39 projecting in a direction parallel to that of said connecting elements and an adjacent indentation 41, parallel, opening at the foot of said tooth. The tooth 39 and the notch 41 are of substantially identical shape and dimensions to cooperate with a notch 41a and a tooth 39a similar, respectively, of another insert 25a belonging to the other connector 13a and enclosing the pair of elements. connection 15a of the male type, as can be seen on the figure 4 .

Sur la figure 5, les connecteurs 13 et 13a sont illustrés dans une position plus rapprochée lors de l'opération de connexion de ces connecteurs 13, 13a. On peut voir ainsi, sur cette figure, comment une surface latérale 100 de la dent 39, qui se prolonge dans l'échancrure 41, entre en contact avec une surface latérale 100a correspondante de la dent 39a. Les inserts 25, 25a sont configurés de manière à ce que les surfaces 100, 100a exercent une pression latérale l'une contre l'autre, en particulier dans la position finale illustrée sur la figure 6, dans laquelle ces surfaces 100, 100a forment un segment central de la chicane 37, de manière à assurer la continuité diélectrique entre les inserts.On the figure 5 , the connectors 13 and 13a are illustrated in a closer position during the connection operation of these connectors 13, 13a. You can see thus, in this figure, how a lateral surface 100 of the tooth 39, which extends into the notch 41, contacts a corresponding lateral surface 100a of the tooth 39a. The inserts 25, 25a are configured so that the surfaces 100, 100a exert lateral pressure against each other, in particular in the final position illustrated in FIG. figure 6 wherein said surfaces 100, 100a form a central segment of the baffle 37 so as to provide dielectric continuity between the inserts.

Comme les dents 39, 39a et les échancrures 41, 41a sont de dimensions sensiblement identiques, les ensembles formés par la dent 39, 39a et l'échancrure 41, 41a de chaque insert 25, 25a peuvent être considérés hermaphrodites. Le caractère hermaphrodite de ces ensembles dent-échancrure permet d'utiliser des inserts 25, 25a sensiblement identiques pour les deux connecteurs 13, 13a, réduisant ainsi le coût de production. Bien entendu, un insert renfermant des éléments de connexion de type femelle est appelé à être abouté à un insert renfermant des éléments de connexion de type mâle et réciproquement. Un connecteur conforme à l'invention peut donc renfermer des paires d'éléments de connexion mâle ou des paires d'éléments de connexion femelle. Il peut aussi renfermer des paires d'éléments de connexion mâle et des paires d'éléments de connexion femelle.As the teeth 39, 39a and notches 41, 41a are of substantially identical dimensions, the sets formed by the tooth 39, 39a and notch 41, 41a of each insert 25, 25a can be considered hermaphroditic. The hermaphroditic nature of these tooth-notch assemblies makes it possible to use inserts 25, 25a that are substantially identical for the two connectors 13, 13a, thus reducing the cost of production. Of course, an insert containing female-type connection elements is called to be butted to an insert containing male-type connection elements and vice versa. A connector according to the invention can therefore contain pairs of male connection elements or pairs of female connection elements. It can also contain pairs of male connection elements and pairs of female connection elements.

Comme on le voit plus particulièrement sur la figure 2, ledit insert 25 comporte deux tronçons sensiblement cylindriques 45, 47 accolés longitudinalement. La dent 39 est définie dans le prolongement latéral de l'un des tronçons tandis que l'échancrure 41 s'étend latéralement dans la portion d'extrémité de l'autre tronçon.As we see more particularly on the figure 2 said insert 25 has two substantially cylindrical sections 45, 47 joined longitudinally. The tooth 39 is defined in the lateral extension of one of the sections while the notch 41 extends laterally in the end portion of the other section.

L'insert 25 est d'une seule pièce.The insert 25 is in one piece.

Comme indiqué précédemment, le connecteur peut constituer une fiche reliée à un cordon renfermant les différents conducteurs électriques isolés. Il peut aussi constituer une embase propre à être montée sur un support d'un appareil électronique quelconque.As indicated above, the connector may constitute a plug connected to a cord enclosing the various insulated electrical conductors. It may also constitute a base adapted to be mounted on a support of any electronic device.
