Description

La présente invention est relative à un connecteur électrique coaxial du type comportant un élément mâle et un élément femelle susceptibles d'être connectés l'un à l'autre de façon amovible, comprenant, sur les éléments de connecteur, des moyens de verrouillage coopérants, résistant à la traction axiale, et des moyens de déverrouillage aptes à provoquer une libération desdits moyens de verrouillage pour permettre une séparation des éléments de connecteur.The present invention relates to a coaxial electrical connector of the type comprising a male element and a female element capable of being connected to each other in a removable manner, comprising, on the connector elements, cooperating locking means, resistant to axial traction, and unlocking means capable of causing a release of said locking means to allow separation of the connector elements.

La société déposante a déjà décrit dans FR-A-2 492 598 un connecteur électrique de ce type assurant de bonnes propriétés de connexion électrique et de tenue mécanique, notamment à la traction axiale, tout en ne nécessitant que des efforts faibles pour l'accouplement et le désaccouplement des éléments du connecteur.The applicant company has already described in FR-A-2 492 598 an electrical connector of this type ensuring good properties of electrical connection and mechanical strength, in particular in axial traction, while requiring only low forces for coupling and uncoupling of the connector elements.

Dans ce document, chacun des éléments de connecteur comporte un contact central, de type broche et respectivement douille, susceptible de coopérer avec le contact central de l'autre élément lors de la connexion, l'un des éléments comportant un contact extérieur de masse en forme de douille dont la paroi extérieure comporte une gorge annulaire de profil concave, l'autre élément de connecteur comportant un contact extérieur de masse comprenant une douille à élasticité radiale et un corps dans lequel est réalisée une cavité dans laquelle est logé et retenu un jonc élastique annulaire, de contour ouvert, comportant des saillies radiales, susceptible de s'engager dans la gorge annulaire du premier élément de connecteur lors du rapprochement axial des deux éléments de connecteur, et un manchon périphérique de déverrouillage susceptible de coulisser le long du second élément de connecteur et comportant une paroi annulaire destinée à venir en contact avec ledit jonc élastique et repousser ce dernier dans ladite cavité de manière à le dégager de la gorge du premier élément de connecteur.In this document, each of the connector elements comprises a central contact, of pin and socket type respectively, capable of cooperating with the central contact of the other element during connection, one of the elements comprising an external ground contact in form of socket, the outer wall of which comprises an annular groove of concave profile, the other connector element comprising an external ground contact comprising a socket with radial elasticity and a body in which a cavity is made in which a rod is housed and retained annular elastic, of open contour, comprising radial projections, capable of engaging in the annular groove of the first connector element when the two connector elements are brought together axially, and a peripheral unlocking sleeve capable of sliding along the second element connector and having an annular wall intended to come into contact with said j elastic wave and push the latter into said cavity so as to release it from the groove of the first connector element.

Dans le connecteur connu le jonc élastique se compose d'une bande découpée de matériau élastique comprenant une pluralité de saillies espacées présentant une surface incurvée, la cavité annulaire destinée à loger et retenir le jonc présentant deux parois inclinées, l'une réalisée par usinage du corps de l'élément de connecteur correspondant, l'autre faisant partie d'une bague sertie à l'extrémité dudit corps. Des moyens supplémentaires tels qu'une patte annulaire, sont en outre prévus pour assurer la retenue du jonc dans la cavité du corps.In the known connector, the elastic rod consists of a cut strip of elastic material comprising a plurality of spaced projections having a curved surface, the annular cavity intended to house and retain the rod having two inclined walls, one produced by machining the body of the corresponding connector element, the other part of a ring crimped at the end of said body. Additional means, such as an annular tab, are also provided for retaining the rod in the body cavity.

Compte tenu des faibles dimensions de tels connecteurs, la réalisation de tels joncs et de telles cavités dans le corps d'un élément du connecteur est complexe et relativement coûteuse.Given the small dimensions of such connectors, the production of such rods and such cavities in the body of a connector element is complex and relatively expensive.

De plus, la cavité destinée à loger et retenir le jonc élastique est réalisée dans le corps du second élément de connecteur à une distance radiale relativement importante de la douille élastique du contact de masse de ce second élément de connecteur pour permettre à la douille du premier élément de connecteur de venir se loger dans un espace annulaire prévu entre ladite douille élastique ladite cavité logeant le jonc élastique. Ceci accroît notablement l'encombrement en sens radial du connecteur et donc son diamètre extérieur.In addition, the cavity intended to accommodate and retain the elastic ring is produced in the body of the second connector element at a relatively large radial distance from the elastic sleeve of the ground contact of this second connector element to allow the sleeve of the first connector element to be housed in an annular space provided between said elastic socket said cavity housing the elastic ring. This notably increases the space requirement in the radial direction of the connector and therefore its outside diameter.

La présente invention se propose de fournir un connecteur permettant une fabrication simplifiée et donc moins onéreuse du jonc élastique et de l'élément de connecteur destiné à le recevoir, tout en réduisant notablement l'encombrement en sens radial de cet élément de connecteur.The present invention proposes to provide a connector allowing a simplified and therefore less expensive manufacture of the elastic ring and of the connector element intended to receive it, while notably reducing the space requirement in the radial direction of this connector element.

Le connecteur selon la présente invention se caractérise essentiellement par le fait que la douille élastique du contact extérieur de masse du second élément de connecteur présente un diamètre correspondant sensiblement au diamètre de la paroi annulaire du manchon périphérique de déverrouillage, ladite douille élastique présentant une extrémité frontale disposée à l'intérieur de ladite cavité annulaire du corps du second élément de connecteur, et que le jonc élastique comporte, des parties inclinées en saillie radialement vers l'extérieur et disposées entre les extrémités en regard de la douille élastique et de la paroi annulaire du manchon périphérique.The connector according to the present invention is essentially characterized in that the elastic sleeve of the external earth contact of the second connector element has a diameter corresponding substantially to the diameter of the annular wall of the peripheral unlocking sleeve, said elastic sleeve having a front end disposed inside said annular cavity of the body of the second connector element, and which the elastic ring comprises, inclined portions projecting radially outwards and disposed between the opposite ends of the elastic sleeve and the annular wall of the peripheral sleeve.

Le jonc élastique présente avantageusement en section une forme de V à pointe tronquée c'est-à-dire avec une âme centrale cylindrique et, de part et d'autre de celle-ci, deux branches latérales inclinées en saillie radialement vers l'extérieur formant entre elles un angle de préférence de l'ordre de 90°, et disposées respectivement en regard de l'extrémité de la douille élastique du second élément de connecteur et de l'extrémité de la paroi annulaire du manchon périphérique de déverrouillage.The elastic ring advantageously has in section a V-shape with a truncated point, that is to say with a cylindrical central core and, on either side of it, two lateral branches inclined projecting radially outwards. forming between them an angle preferably of the order of 90 °, and disposed respectively opposite the end of the elastic sleeve of the second connector element and the end of the annular wall of the peripheral unlocking sleeve.

De préférence, les faces d'extrémité de la douille élastique du second élément de connecteur et de la paroi annulaire du manchon périphérique de déverrouillage sont chanfreinées pour contribuer au guidage radial vers l'extérieur du jonc élastique dans la cavité du corps du second élément de connecteur lors de la déconnexion.Preferably, the end faces of the elastic sleeve of the second connector element and of the annular wall of the peripheral unlocking sleeve are chamfered to contribute to the radial outward guidance of the elastic ring in the cavity of the body of the second element of connector when disconnected.

On comprend ainsi que, contrairement à ce qui est le cas dans le document antérieur, la cavité annulaire du corps du second élément de connecteur n'a plus besoin de comporter deux parois inclinées, une seule paroi inclinée étant suffisante pour assurer un guidage de l'extrémité d'une des branches inclinées du jonc annulaire lors du déverrouillage et, de plus, aucun élément de maintien supplémentaire n'est nécessaire pour retenir le jonc dans la cavité correspondante en position désassemblée du connecteur.It will thus be understood that, contrary to what is the case in the prior document, the annular cavity of the body of the second connector element no longer needs to have two inclined walls, a single inclined wall being sufficient to ensure guidance of the end of one of the inclined branches of the annular ring when unlocked and, in addition, no additional holding element is necessary to retain the ring in the corresponding cavity in the disassembled position of the connector.

Dans le but de mieux faire comprendre l'invention on va maintenant décrire à titre d'exemples non limitatifs deux modes de réalisation en se référant au dessin annexé dans lequel :

  • la figure 1 est une vue en élévation, partiellement en coupe, représentant les parties d'extrémité des éléments d'un connecteur coaxial selon l'invention en position désaccouplée,
  • la figure 2 représente les parties d'extrémité des éléments du connecteur coaxial de la figure 1 en position accouplée,
  • la figure 3 illustre ces mêmes éléments en cours de désaccouplement,
  • la figure 4 illustre un mode de réalisation de jonc élastique utilisable dans le connecteur selon l'invention, et
  • la figure 5 est une vue analogue à la figure 1 d'une variante de connecteur coaxial selon l'invention.
In order to better understand the invention, we will now describe, by way of nonlimiting examples, two embodiments with reference to the appended drawing in which:
  • FIG. 1 is an elevational view, partially in section, showing the end parts of the elements of a coaxial connector according to the invention in the uncoupled position,
  • FIG. 2 represents the end parts of the elements of the coaxial connector of FIG. 1 in the coupled position,
  • FIG. 3 illustrates these same elements during uncoupling,
  • FIG. 4 illustrates an embodiment of an elastic ring usable in the connector according to the invention, and
  • Figure 5 is a view similar to Figure 1 of a variant of coaxial connector according to the invention.

On se réfère tout d'abord aux figures 1 à 4.We first refer to Figures 1 to 4.

Un connecteur coaxial selon l'invention se compose d'un premier élément de connecteur désigné globalement par 1 et d'un second élément de connecteur désigné globalement par 2.A coaxial connector according to the invention consists of a first connector element generally designated by 1 and a second connector element generally designated by 2.

Le premier élément de connecteur 1 est agencé en élément mâle et comprend un contact central en forme de broche 3, un contact de masse extérieur en forme de douille 4 et un manchon isolant 5. Dans la paroi périphérique de la douille de contact extérieur 4, est réalisée une gorge annulaire 6. Plus précisément, la gorge 6 présente un profil correspondant au profil du jonc annulaire, qui sera décrit plus en détail ci-après, pour en assurer une bonne retenue en position d'accouplement. La gorge 6 comporte ainsi dans l'exemple illustré un profil en forme de V tronqué avec une paroi de fond cylindrique et deux parois latérales tronconiques.The first connector element 1 is arranged as a male element and comprises a central pin-shaped contact 3, an external ground contact in the form of a socket 4 and an insulating sleeve 5. In the peripheral wall of the external contact sleeve 4, an annular groove 6 is produced. More specifically, the groove 6 has a profile corresponding to the profile of the annular ring, which will be described in more detail below, to ensure good retention in the coupling position. The groove 6 thus comprises in the example illustrated a truncated V-shaped profile with a cylindrical bottom wall and two frustoconical side walls.

L'extrémité frontale de la douille 4 présente un chanfrein d'extrémité 7.The front end of the sleeve 4 has an end chamfer 7.

L'élément de connecteur complémentaire 2, agencé en élément femelle, comporte un contact central en forme de douille 8 dont la partie d'extrémité présente une élasticité en sens radial, procurée, de manière connue, par exemple par des fentes longitudinales, et un contact extérieur de masse comprenant une douille 9 à élasticité radiale et un corps constitué de deux parties 10 et respectivement 11. Les parties 10 et 11 du corps sont solidaires et réalisées, comme illustré sur le dessin, de manière à définir une cavité annulaire 12 délimitée vers l'avant par une paroi inclinée 14 formée sur la partie 11 du corps et vers l'arrière par une paroi droite 15 réalisée dans la partie 10 du corps.The complementary connector element 2, arranged as a female element, has a central socket-shaped contact 8, the part of which end has a radial elasticity, provided in a known manner, for example by longitudinal slots, and an external ground contact comprising a socket 9 with radial elasticity and a body consisting of two parts 10 and 11 respectively. 10 and 11 of the body are integral and produced, as illustrated in the drawing, so as to define an annular cavity 12 delimited towards the front by an inclined wall 14 formed on the part 11 of the body and towards the rear by a straight wall 15 performed in part 10 of the body.

La douille 9 présente une élasticité radiale par la présence, de manière connue, de fentes longitudinales s'étendant à partir de son extrémité, cette extrémité 16 étant en outre chanfreinée et étant disposée à l'intérieur de la cavité annulaire 12.The sleeve 9 has a radial elasticity by the presence, in a known manner, of longitudinal slots extending from its end, this end 16 being furthermore chamfered and being disposed inside the annular cavity 12.

L'élément de connecteur 2 comprend en outre un isolant 17 entre le contact central 8 et le contact extérieur, et un jonc élastique annulaire 18 de section sensiblement en V à pointe tronquée.The connector element 2 further comprises an insulator 17 between the central contact 8 and the external contact, and an annular elastic ring 18 of substantially V-shaped section with truncated tip.

La structure du jonc 18 qui constitue un composant séparé est le mieux vue sur la figure 4. Le jonc est fendu, en 19, et comporte une âme centrale cylindrique 20 à partir de laquelle s'étendent, en saillie radialement vers l'extérieur, deux branches 21 et 22.The structure of the rod 18 which constitutes a separate component is best seen in FIG. 4. The rod is split, at 19, and comprises a cylindrical central core 20 from which extend, projecting radially outwards, two branches 21 and 22.

Le jonc 18 est réalisé en matériau élastique, par exemple en cuivre au béryllium.The rod 18 is made of elastic material, for example beryllium copper.

L'élément de connecteur 2 comprend un organe de déverrouillage constitué d'un manchon périphérique 23 susceptible de coulisser le long de la paroi périphérique de la partie 10 du corps, ce manchon comportant une paroi annulaire 24 pourvue d'un chanfrein d'extrémité 25 et s'engageant à l'intérieur du corps.The connector element 2 comprises an unlocking member constituted by a peripheral sleeve 23 capable of sliding along the peripheral wall of the part 10 of the body, this sleeve comprising an annular wall 24 provided with an end chamfer 25 and engaging inside the body.

Le diamètre de la paroi annulaire 24 du manchon 23 correspond sensiblement au diamètre de la douille élastique 9, de sorte que les extrémités chanfreinées 16 de la douille, et 25 de la paroi annulaire, se trouvent sensiblement en regard l'une de l'autre de part et d'autre des branches 21 et 22 du jonc élastique 18.The diameter of the annular wall 24 of the sleeve 23 corresponds substantially to the diameter of the elastic sleeve 9, so that the chamfered ends 16 of the sleeve, and 25 of the annular wall, lie substantially opposite one another on either side of the branches 21 and 22 of the elastic ring 18.

Pour réaliser le verrouillage du connecteur à partir de la position désassemblée de la figure 1, il suffit d'enfoncer l'élément de connecteur 1 à l'intérieur de l'élément de connecteur 2 jusqu'à ce que le jonc élastique 18 vienne s'encliqueter dans la gorge 6. Cet enfoncement peut être réalisé en exerçant un effort de poussée sur le mancheon 23 ou la partie 10 du corps.To lock the connector from the disassembled position in FIG. 1, it suffices to push the connector element 1 inside the connector element 2 until the elastic ring 18 comes s 'snap into the groove 6. This depression can be achieved by exerting a pushing force on the handle 23 or part 10 of the body.

La position assemblée est illustrée à la figure 2.The assembled position is illustrated in Figure 2.

On voit sur cette figure que le jonc annulaire 18 maintenu dans la gorge 6 se trouve positionné axialement entre les extrémités de la douille 9 et de la paroi annulaire 24 du manchon de déverrouillage 23.It can be seen in this figure that the annular rod 18 held in the groove 6 is positioned axially between the ends of the sleeve 9 and of the annular wall 24 of the unlocking sleeve 23.

Si une traction axiale est exercée sur la partie de corps 10, en position assemblée du connecteur, le jonc annulaire 18 reste maintenu dans la gorge 6 en étant coincé entre la paroi latérale de droite (sur le dessin) de la gorge 6 et la paroi inclinée 14 de la partie 11 du corps.If an axial traction is exerted on the body part 10, in the assembled position of the connector, the annular ring 18 remains held in the groove 6 by being wedged between the right side wall (in the drawing) of the groove 6 and the wall inclined 14 of part 11 of the body.

Pour réaliser le déverrouillage à partir de la position assemblée de la figure 2, on repousse le manchon de déverrouillage dans le sens de la flèche A de la figure 3. Le chanfrein 25 de la paroi annulaire 24 vient coopérer avec la branche inclinée 21 du jonc 18 et écarter le jonc 18 de la gorge 6. En continuant à tirer sur le manchon de déverrouillage on assure la déconnexion des deux éléments du connecteur.To carry out the unlocking from the assembled position of FIG. 2, the unlocking sleeve is pushed back in the direction of the arrow A in FIG. 3. The chamfer 25 of the annular wall 24 cooperates with the inclined branch 21 of the rod 18 and move the rod 18 away from the groove 6. By continuing to pull on the unlocking sleeve, the two elements of the connector are disconnected.

Lorsque l'on relache le manchon celui-ci revient dans sa position avant, illustrée aux figures 1 et 2, sous l'action du jonc élastique 18 qui se referme et retrouve sa position libre, illustrée à la figure 4.When the sleeve is released, it returns to its front position, illustrated in FIGS. 1 and 2, under the action of the elastic ring 18 which closes and returns to its free position, illustrated in FIG. 4.

Le connecteur illustré à la figure 5 diffère uniquement de celui des figures 1 à 3 par le fait que le corps 11′ du contact extérieur de masse du second élément de connecteur 2 est réalisé d'un seul tenant et non plus par deux parties assemblées 10 et 11.The connector illustrated in FIG. 5 differs only from that of FIGS. 1 to 3 by the fact that the body 11 ′ of the external ground contact of the second connector element 2 is produced in one piece and no longer by two assembled parts 10 and 11.

Cette réalisation permet de réduire encore davantage l'encombrement en sens radial du second élément de connecteur et donc son diamètre extérieur.This embodiment makes it possible to further reduce the space requirement in the radial direction of the second connector element and therefore its outside diameter.
