Description

La présente invention a trait à un connecteur électrique notamment coaxial du type comprenant un élément mâle et un élément femelle susceptibles d'être connectés l'un à l'autre de façon amovible.The present invention relates to an electrical connector in particular coaxial of the type comprising a male element and a female element capable of being connected to one another in a removable manner.

D'une façon générale, les connecteurs comprennent sur un des éléments, au moins une broche destinée à pénétrer dans au moins une douille correspondante de l'autre élément. En outre, des pièces de liaison sont prévues pour assurer une liaison libérable des éléments de connecteur.Generally, the connectors comprise on one of the elements, at least one pin intended to penetrate into at least one corresponding socket of the other element. In addition, connecting parts are provided to ensure a releasable connection of the connector elements.

Il existe déjà divers types de liaisons libérables permettant de réaliser un verrouillage et un déverrouillage rapides du connecteur, notamment pour un connecteur coaxial.There are already various types of releasable connections allowing rapid locking and unlocking of the connector, in particular for a coaxial connector.

On connaît ainsi des liaisons de type à baïonnette. On connaît également des liaisons comportant sur l'un des éléments de connecteur, plus précisément sur la surface extérieure de la douille de conducteur périphérique dans le cas d'un connecteur coaxial, une gorge annulaire, de profil concave, dans laquelle peuvent s'engager par encliquetage, lors du rapprochement axial des éléments de connecteur, des pièces, telles que des billes logées dans l'autre élément de connecteur.Bayonet type connections are thus known. Also known are connections comprising on one of the connector elements, more precisely on the outer surface of the peripheral conductor socket in the case of a coaxial connector, an annular groove, of concave profile, in which can engage by snap-fastening, when the connector elements are brought together axially, parts, such as balls housed in the other connector element.

On connaît enfin par le brevet français de la déposante FR-A-2204331 un connecteur électrique à verrouillage et déverrouillage rapides du type comportant sur un des éléments de connecteur au moins une broche destinée à pénétrer dans au moins une douille centrale correspondante de l'autre élément de connecteur, ledit connecteur comportant une gorge annulaire dans la paroi extérieure d'une douille d'un premier élément de connecteur et, dans une cavité annulaire du second élément de connecteur, un jonc élastique annulaire de contour ouvert, comportant au moins une saillie radiale présentant une surface incurvée et susceptible de s'engager dans la gorge annulaire du premier élément de connecteur lors du rapprochement axial des deux éléments de connecteur, un manchon périphérique de déverrouillage étant prévu pour dégager le jonc élastique de la gorge du premier élément de connecteur.Finally, from the French patent of the applicant FR-A-2204331, an electrical connector with quick locking and unlocking of the type is known comprising on one of the connector elements at least one pin intended to penetrate into at least one corresponding central socket of the other connector element, said connector comprising an annular groove in the external wall of a socket of a first connector element and, in an annular cavity of the second connector element, an annular elastic ring of open outline, comprising at least one projection radial having a curved surface and capable of engaging in the annular groove of the first connector element during the axial approximation of the two connector elements, a peripheral unlocking sleeve being provided for releasing the elastic ring from the groove of the first connector element .

Les liaisons connues présentent notamment l'inconvénient de n'assurer, en position assemblée du connecteur, qu'une résistance relativement faible à la traction axiale. En outre elles nécessitent des efforts relativement élevés pour l'accouplement et le désaccouplement.Known connections in particular have the drawback of ensuring, in the assembled position of the connector, that a relatively low resistance to axial traction. In addition, they require relatively high efforts for coupling and uncoupling.

De plus, ces connecteurs doivent présenter du fait de leur taille très réduite, une très grande précision dimensionnelle, ce qui exige un usinage très précis des différents composants entraînant un prix de revient élevé.In addition, these connectors must have, because of their very small size, very high dimensional accuracy, which requires very precise machining of the various components resulting in a high cost price.

La présente invention se propose de réaliser un connecteur électrique à verrouillage et déver- touillage rapides évitant les inconvénients des connecteurs actuellement connus, étant d'un prix de revient économique, grâce à sa simplicité de fabrication, tout en assurant de bonnes propriétés de connexion électrique et de tenue mécanique, notamment à la traction axiale.The present invention proposes to produce an electrical connector with rapid locking and unlocking avoiding the drawbacks of currently known connectors, being of an economic cost price, thanks to its simplicity of manufacture, while ensuring good electrical connection properties. and mechanical strength, in particular to axial traction.

Le connecteur électrique selon l'invention se caractérise par le fait que la gorge annulaire du premier élément de connecteur présente un profil concave, que la cavité du second élément de connecteur présente des parois inclinées par rapport à l'axe du connecteur, l'angle d'inclinaison desdites parois par rapport à un plan parallèle à l'axe de celui-ci étant inférieur ou égal à l'angle entre la génératrice de la surface périphérique de la douille dans laquelle est réalisée ladite gorge et la tangente à ladite gorge annulaire au point d'intersection de celle-ci avec ladite génératrice, que ledit second élément de connecteur comporte des moyens pour retenir le jonc élastique dans ladite cavité.The electrical connector according to the invention is characterized in that the annular groove of the first connector element has a concave profile, that the cavity of the second connector element has walls inclined relative to the axis of the connector, the angle of inclination of said walls relative to a plane parallel to the axis thereof being less than or equal to the angle between the generatrix of the peripheral surface of the sleeve in which said groove is made and the tangent to said annular groove at the point of intersection thereof with said generator, that said second connector element comprises means for retaining the elastic ring in said cavity.

Ainsi, l'angle d'inclinaison des parois de la cavité du second élément de connecteur est compris entre 30° et 60° et est de préférence d'environ 45°.Thus, the angle of inclination of the walls of the cavity of the second connector element is between 30 ° and 60 ° and is preferably about 45 °.

Dans un mode de réalisation particulier, l'une des parois de la cavité est réalisée par usinage du corps dudit second élément de connecteur, l'autre paroi faisant partie d'une bague sertie sur ledit corps.In a particular embodiment, one of the walls of the cavity is produced by machining the body of said second connector element, the other wall forming part of a ring crimped on said body.

Divers modes de réalisation de joncs élastiques peuvent être envisagés dans le cadre de l'invention.Various embodiments of elastic rods can be envisaged in the context of the invention.

Ainsi le jonc élastique peut être réalisé par découpe dans une bande de matériau élastique tel que par exemple du cuivre au béryllium ou de l'acier inoxydable, les saillies, par exemple au nombre de trois, étant réalisées par des pattes découpées et rabattues vers l'intérieur. Dans ce cas, les pattes sont avantageusement équidistantes et réparties en 120° sur la périphérie du jonc.Thus the elastic ring can be produced by cutting from a strip of elastic material such as, for example, beryllium copper or stainless steel, the projections, for example three in number, being produced by tabs cut and folded towards the inside. In this case, the legs are advantageously equidistant and distributed in 120 ° on the periphery of the rod.

En variante, il est possible de réaliser le jonc élastique sous la forme d'un fil ressort sur lequel les saillies également par exemple au nombre de trois, peuvent être réparties à 120° et être constituées chacune d'un galet cylindrique, d'une bille sphérique ou sphérique tronquée.As a variant, it is possible to produce the elastic ring in the form of a spring wire on which the projections also, for example three in number, can be distributed at 120 ° and each consist of a cylindrical roller, of a spherical or truncated spherical ball.

Les moyens de retenue du jonc élastique dans la cavité à parois inclinées devront être adaptés à la structure particulière du jonc utilisé. Dans le cas d'un jonc élastique réalisé par découpe d'une bande de matériau élastique, les moyens de retenue peuvent être constitués par une bordure annulaire du corps du second élément de connecteur, formant patte de maintien et prolongeant la paroi de la cavité réalisée dans cet élément de connecteur.The means of retaining the elastic rod in the cavity with inclined walls must be adapted to the particular structure of the rod used. In the case of an elastic ring produced by cutting a strip of elastic material, the retaining means may consist of an annular edge of the body of the second connector element, forming a retaining tab and extending the wall of the cavity produced in this connector element.

Selon l'invention tous les composants des éléments de connecteur sont ainsi des pièces de révolution qui peuvent être réalisées par décolletage, ce qui permet une fabrication particulièrement économique.According to the invention all the components of the connector elements are thus parts of revolution which can be produced by bar turning, which allows a particularly economical manufacture.

Dans le but de mieux faire comprendre l'invention on va décrire à titre d'exemple non limitatif un mode de réalisation, en se référant au dessin annexé dans lequel :

  • La figure 1 représente les parties d'extrémité des éléments d'un connecteur coaxial selon l'invention en position désaccouplée.
  • La figure 2 représente des parties d'extrémité des éléments d'un connecteur coaxial selon l'invention en position accouplée, et,
  • La figure 3 illustre ces mêmes éléments en cours de désaccouplement.
  • Les figures 4 à 7 illustrent différents modes de réalisation de joncs élastiques utilisables dans le connecteur selon l'invention.
In order to better understand the invention we will describe by way of non-limiting example an embodiment, with reference to the appended drawing in which:
  • FIG. 1 shows the end parts of the elements of a coaxial connector according to the invention in the uncoupled position.
  • FIG. 2 represents end parts of the elements of a coaxial connector according to the invention in the coupled position, and,
  • FIG. 3 illustrates these same elements during uncoupling.
  • Figures 4 to 7 illustrate different embodiments of elastic rods usable in the connector according to the invention.

On se réfère tout d'abord aux figures 1 à 3.We first refer to Figures 1 to 3.

Le connecteur selon l'invention se compose d'un élément de connecteur femelle désigné globalement par 1 et d'un élément de connecteur mâle désigné globalement par 2.The connector according to the invention consists of a female connector element generally designated by 1 and a male connector element generally designated by 2.

L'élément de connecteur femelle comprend un contact central en forme de douille élastique 3, un contact de masse extérieur également en forme de douille 4 et un manchon isolant 5. Dans la paroi périphérique de la douille de contact extérieur est réalisée une gorge annulaire de profil concave 6.The female connector element comprises a central contact in the form of an elastic socket 3, an external ground contact also in the form of a socket 4 and an insulating sleeve 5. In the peripheral wall of the external contact socket is formed an annular groove concave profile 6.

L'élément de connecteur complémentaire mâle 2 présente un contact central en forme de tige axiale 7 et un contact extérieur de masse comprenant une douille élastique 8 et un corps 9 dans lequel est réalisée une cavité 10 à parois 11 et 12 parallèles entre elles et inclinées par rapport à l'axe du connecteur. La paroi 11 est réalisée par usinage du corps 9 de l'élément de connecteur 2, la paroi 12 faisant partie d'une bague 13 sertie à l'extrémité du corps 9.The complementary male connector element 2 has a central contact in the form of an axial rod 7 and an external ground contact comprising an elastic socket 8 and a body 9 in which a cavity 10 with walls 11 and 12 parallel to one another and inclined is produced. relative to the axis of the connector. The wall 11 is produced by machining the body 9 of the connector element 2, the wall 12 forming part of a ring 13 crimped at the end of the body 9.

L'élément de connecteur 2 comprend en outre un isolant 14 entre le contact central 7 et le contact extérieur, et un jonc élastique annulaire 15 logé dans la cavité 10 en appui contre ses parois. Le jonc 15 comprend au moins une saillie radiale 16.The connector element 2 further comprises an insulator 14 between the central contact 7 and the external contact, and an annular elastic ring 15 housed in the cavity 10 bearing against its walls. The rod 15 comprises at least one radial projection 16.

Le jonc élastique du mode de réalisation des figures 1 à 3 est illustré dans la figure 4. Il se compose d'une bande découpée de matériau élastique de contour non fermé, comprenant trois saillies 16 espacées de 120° sur la périphérie du jonc 15. Chacune des saillies présente une surface incuvée 17.The elastic ring of the embodiment of FIGS. 1 to 3 is illustrated in FIG. 4. It consists of a cut strip of elastic material with an unclosed outline, comprising three projections 16 spaced 120 ° apart on the periphery of the ring 15. Each of the projections has an incubated surface 17.

Le jonc 15 est retenu dans la gorge 10 par une patte annulaire de maintien 18.The rod 15 is retained in the groove 10 by an annular retaining lug 18.

Enfin l'élément de connecteur 2 comprend un organe de déverrouillage constitué d'un manchon périphérique 19 susceptible de coulisser le long de la paroi périphérique du corps 9, ce manchon comportant une paroi annulaire 20 s'engageant sous la bague sertie 13 et susceptible de venir en contact 15 pour assurer le déverrouillage du connecteur comme cela sera expliqué par la suite.Finally, the connector element 2 comprises an unlocking member constituted by a peripheral sleeve 19 capable of sliding along the peripheral wall of the body 9, this sleeve comprising an annular wall 20 engaging under the crimped ring 13 and capable of come into contact 15 to ensure the unlocking of the connector as will be explained later.

Les figures 5 à 7 représentent diverses variantes de joncs utilisables selon l'invention et comprenant chacun un fil ressort 21 recourbé selon un profil circulaire non fermé et présentant trois pièces en saillie espacées de 120°. Dans le mode de réalisation de la figure 5 les pièces en saillie sont des galets cylindriques 22 dans le mode de réalisation de la figure 6 des sphères 23 et dans le mode de réalisation de la figure 4 des sphères tronquées 24.FIGS. 5 to 7 show various variants of rods usable according to the invention and each comprising a spring wire 21 curved according to an unclosed circular profile and having three projecting parts spaced 120 ° apart. In the embodiment of FIG. 5 the projecting parts are cylindrical rollers 22 in the embodiment of FIG. 6 of the spheres 23 and in the embodiment of FIG. 4 of the truncated spheres 24.

En supposant que l'élément de connecteur 1 soit fixe, pour réaliser l'assemblage et le verrouillage des éléments de connecteur 1 et 2 à partir de la position déverrouillée représentée à la figure 1, il suffit de rapprocher axialement les deux éléments de connecteur, en poussant vers la gauche soit sur le corps 9, soit sur le manchon 19 jusqu'à ce que les saillies 16 du jonc élastique 15 viennent s'engager par encliquetage dans la gorge annulaire 6.Assuming that the connector element 1 is fixed, in order to assemble and lock the connector elements 1 and 2 from the unlocked position shown in FIG. 1, it suffices to bring the two connector elements axially together, by pushing to the left either on the body 9 or on the sleeve 19 until the projections 16 of the elastic ring 15 engage by snap-fastening in the annular groove 6.

Dans cette position de verrouillage représentée dans la figure 2, une bonne résistance à la traction axiale est assurée par l'immobilisation du jonc entre la paroi 12 de la cavité 10 de l'élément de connecteur 2 et la gorge 6 de l'élément de connecteur 1. Pour assurer une telle tenue mécanique il est nécessaire que l'angle d'inclinaison a de paroi 12 de la cavité 10 par rapport à un plan parallèle à l'axe du connecteur soit inférieur ou égal à l'angle p entre la tangente à la gorge 6 et la génératrice de la surface périphérique de la douille 4.In this locking position shown in FIG. 2, good resistance to axial traction is ensured by immobilizing the rod between the wall 12 of the cavity 10 of the connector element 2 and the groove 6 of the element of connector 1. To ensure such mechanical strength, it is necessary that the angle of inclination a of the wall 12 of the cavity 10 relative to a plane parallel to the axis of the connector is less than or equal to the angle p between the tangent to the groove 6 and the generatrix of the peripheral surface of the sleeve 4.

En supposant toujours que l'élément de connecteur 1 soit fixe, pour assurer le déverrouillage du connecteur à partir de la position représentée dans la figure 2, on fait coulisser axialement comme matérialisé par les flèches A de la figure 3, le manchon 19 le long du connecteur, l'extrémité de la paroi annulaire 20 de ce manchon venant repousser dans la gorge 10 le jonc annulaire 15 en prenant appui sur la ou les saillies radiales 16. A partir de la position représentée dans la figure 3 il suffit de continuer à tirer vers la droite la bague 19 ou le corps 9 pour assurer une séparation complète des deux éléments de connecteur.Always assuming that the connector element 1 is fixed, to ensure the unlocking of the connector from the position shown in FIG. 2, the sleeve 19 is made to slide axially as shown by the arrows A in FIG. 3 of the connector, the end of the annular wall 20 of this sleeve pushing in the groove 10 the annular ring 15 while bearing on the radial projection (s) 16. From the position represented in FIG. 3, it suffices to continue pull the ring 19 or the body 9 to the right to ensure complete separation of the two connector elements.
