Description

La présente invention concerne un élément de connecteur électrique coaxial réalisant également une fonction de commutation, en permettant de commuter une ligne électrique sur une autre ligne électrique.The present invention relates to a connector element electric coaxial also performing a switching function, in for switching an electrical line to another line electric.

Un élément de connecteur conforme au préambule de la revendication 1 est connu de EP-A-0 154 199. D'autres éléments de connecteur avec fonction de commutation sont connus de US-A-2 640 118 et DE-A-2 707 250.A connector element according to the preamble of claim 1 is known from EP-A-0 154 199. Other connector elements with function of switching are known from US-A-2,640,118 and DE-A-2,707,250.

L'invention concerne également un connecteur comprenant un tel élément de connecteur.The invention also relates to a connector comprising a such connector element.

Des connecteurs connus permettant d'assurer une fonction de commutation comportent deux éléments de connecteur coopérants, qui sont chacun munis d'un conducteur central et d'un conducteur de masse extérieur. L'un des éléments de connecteur comporte en outre une lame métallique flexible, qui prend appui sur le conducteur central à l'état désaccouplé des deux éléments de connecteur, et qui en est écartée par une surface d'appui de l'autre élément de connecteur lorsque les deux éléments de connecteur sont accouplés.Known connectors making it possible to provide a switching have two cooperating connector elements, which are each provided with a central conductor and a ground conductor outside. One of the connector elements further comprises a blade flexible metal, which rests on the central conductor at the uncoupled state of the two connector elements, and which is spaced apart by a bearing surface of the other connector element when the two connector elements are coupled.

Ces connecteurs connus présentent un certain nombre d'inconvénients qui sont liés à la présence de la lame flexible.These known connectors have a number disadvantages which are linked to the presence of the flexible blade.

D'une part, la lame flexible doit présenter une longueur minimale pour pouvoir se courber élastiquement, ce qui limite la possibilité de réduire l'encombrement du connecteur et de permettre la réalisation de connecteurs miniatures à fonction de commutation.On the one hand, the flexible blade must have a length minimum to be able to bend elastically, which limits the possibility of reducing the size of the connector and allowing the realization of miniature connectors with switching function.

Cet inconvénient est particulièrement gênant pour les éléments de connecteur destinés à être montés sur des cartes de circuits imprimés.This drawback is particularly troublesome for connector elements intended to be mounted on boards printed circuits.

D'autre part, les déformations de la lame peuvent, à la longue, lui faire perdre son élasticité et créer des problèmes de fiabilité des contacts électriques.On the other hand, the deformations of the blade can, at the long, cause it to lose its elasticity and create reliability of electrical contacts.

En outre, la lame, en prenant appui sur l'autre élément de connecteur au moment de l'accouplement des deux éléments de connecteur, subit une usure qui peut la fragiliser.In addition, the blade, by resting on the other element of connector when coupling the two elements of connector, undergoes wear which can weaken it.

De plus, la lame est susceptible d'être endommagée ou déformée soit par une pièce qui serait malencontreusement introduite dans l'élément de connecteur par sa face frontale, soit, plus simplement, par un autre élément de connecteur inadapté qui serait accouplé avec l'élément de connecteur comportant la lame.In addition, the blade may be damaged or distorted either by a part which would be inadvertently introduced in the connector element by its front face, that is, more simply, by another unsuitable connector element which would be coupled with the connector element comprising the blade.

La présente invention vise à fournir un élément de connecteur électrique coaxial qui permet de réaliser une commutation de manière fiable et durable et dont la structure permet de le miniaturiser sans difficulté, en particulier pour pouvoir le monter sur une carte de circuit imprimé.The present invention aims to provide an element of coaxial electrical connector for switching reliably and sustainably and whose structure allows it to miniaturize without difficulty, in particular to be able to mount it on a printed circuit board.

La présente invention a pour objet un élément de connecteur électrique coaxial comprenant une face d'accouplement avec un élément de connecteur électrique complémentaire et comportant un conducteur central fixe, une pièce de contact fixe, une pièce conductrice axialement mobile autour du conducteur central fixe, entre une première position dans laquelle elle s'appuie contre le conducteur central fixe d'une part, et la pièce de contact fixe d'autre part, et une seconde position dans laquelle elle est écartée de la pièce de contact fixe, et un organe de rappel apte à ramener la pièce conductrice axialement mobile dans sa première position lorsque l'élément de connecteur n'est pas accouplé à un élément de connecteur complémentaire, caractérisé par le fait que la pièce conductrice axialement mobile est une douille qui comporte une partie frontale accessible depuis la face d'accouplement de l'élément de connecteur et une partie arrière qui s'appuie contre la pièce de contact fixe lorsque ladite douille se trouve dans sa première position.The subject of the present invention is a connector element electric coaxial comprising a coupling face with an element of additional electrical connector and comprising a conductor fixed central, a fixed contact piece, a conductive piece axially movable around the fixed central conductor, between a first position in which it leans against the driver fixed central on the one hand, and the fixed contact part on the other hand, and a second position in which it is moved away from the workpiece fixed contact, and a return member capable of bringing the part back conductive axially movable in its first position when the connector element is not coupled to a connector element complementary, characterized in that the conductive part axially movable is a socket which has a front part accessible from the coupling face of the connector element and a rear part which leans against the fixed contact part when said socket is in its first position.

On comprend que, selon l'invention, lors de l'accouplement de l'élément de connecteur avec un élément de connecteur complémentaire, l'élément de connecteur complémentaire s'appuie directement contre la pièce conductrice mobile et la repousse dans sa seconde position, tout en assurant la mise en contact électrique des conducteurs centraux des deux éléments de connecteurs.It is understood that, according to the invention, during the coupling of the connector element with a connector element complementary, the complementary connector element is supported directly against the moving conductive part and pushes it back into its second position, while ensuring the electrical contacting of the central conductors of the two connector elements.

L'élément de connecteur électrique coaxial selon l'invention présente une bonne fiabilité en raison notamment du fait qu'il comporte, comme seule pièce mobile, la douille conductrice qui coulisse autour de son conducteur central, mais qui prend appui sans frottement contre l'élément de connecteur complémentaire.The coaxial electrical connector element according to the invention has good reliability due in particular to the fact that it comprises, as the only moving part, the conductive sleeve which slides around its central conductor, but which is supported without friction against the complementary connector element.

De plus, la course de déplacement de cette douille conductrice peut-être très faible, ce qui permet de réaliser un connecteur de très petites dimensions. In addition, the displacement travel of this socket conductive maybe very weak, which allows to achieve a very small connector.

Enfin, la douille conductrice n'est pas susceptible d'être endommagée ou déformée car elle peut être aisément réalisée sous une forme robuste et ne présentant aucune prise depuis l'extérieur de l'élément de connecteur dans lequel elle est logée.Finally, the conductive sleeve is not likely to be damaged or deformed because it can be easily performed under a robust shape with no grip from outside the connector element in which it is housed.

Dans un mode de réalisation particulier de l'invention, l'élément de connecteur comporte une plaque de masse entre la pièce de contact et le conducteur central.In a particular embodiment of the invention, the connector element has a ground plate between the part contact and the central conductor.

Cette plaque de masse, qui s'étend de préférence sur une longueur axiale importante, permet d'éviter tout couplage électromagnétique qui pourrait s'établir entre la pièce de contact et le conducteur central lorsque les deux éléments de connecteur sont accouplés.This ground plate, which preferably extends over a large axial length, avoids any coupling electromagnetic which could be established between the contact part and the central conductor when the two connector elements are mated.

La présente invention a également pour objet un connecteur électrique coaxial constitué par un élément de connecteur tel que décrit ci-dessus et un élément de connecteur complémentaire.The present invention also relates to a connector coaxial electric consisting of a connector element such as described above and a complementary connector element.

Dans un mode de réalisation particulier de l'invention, l'élément de connecteur complémentaire comporte un corps isolant intermédiaire qui se situe en avant par rapport à son conducteur central, de manière à repousser la douille mobile et l'écarter de la pièce de contact avant que les deux conducteurs centraux n'entrent en contact électrique.In a particular embodiment of the invention, the complementary connector element comprises an insulating body intermediate which is located in front of its driver central, so as to push back the movable sleeve and move it away from the contact piece before the two central conductors come into contact electric contact.

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

  • la figure 1 est une vue en coupe axiale d'un élément de connecteur électrique coaxial selon un mode de réalisation de l'invention, et d'un élément de connecteur complémentaire,
  • la figure 2 est une vue selon II-II de la figure 1,
  • la figure 3 est une vue analogue à la figure 1 représentant les deux éléments de connecteur en cours d'accouplement, et
  • la figure 4 est une vue analogue à la figure 3 représentant les deux éléments de connecteur accouplés.
In order to better understand the invention, we will now describe an embodiment given by way of nonlimiting example with reference to the accompanying drawing in which:
  • FIG. 1 is a view in axial section of a coaxial electrical connector element according to an embodiment of the invention, and of a complementary connector element,
  • FIG. 2 is a view along II-II of FIG. 1,
  • FIG. 3 is a view similar to FIG. 1 showing the two connector elements during mating, and
  • Figure 4 is a view similar to Figure 3 showing the two coupled connector elements.

On a illustré sur le dessin, un connecteur électrique coaxial miniature qui comporte un élément de connecteur destiné à être monté sur une carte de circuit imprimé (non représentée), de type femelle 1, et un élément de connecteur complémentaire de type mâle 2. Illustrated in the drawing, an electrical connector miniature coaxial which has a connector element intended to be mounted on a printed circuit board (not shown), of the type female 1, and a complementary connector element of male type 2.

L'élément femelle 1 comprend un boítier conducteur externe 3 de forme cylindrique qui présente, dans le cas présent, un diamètre externe de l'ordre de quatre millimètres.The female element 1 comprises an external conductive housing 3 cylindrical in shape, which in this case has a diameter external of the order of four millimeters.

La partie supérieure par rapport au dessin, du boítier conducteur 3 constitue la face d'accouplement F de l'élément de connecteur 1 avec l'élément de connecteur complémentaire 2.The upper part in relation to the drawing, of the housing conductor 3 constitutes the coupling face F of the element of connector 1 with the complementary connector element 2.

A l'intérieur de ce boítier conducteur 3 se trouve un premier corps isolant cylindrique 4 fermé, du côté de la face d'accouplement F, par une paroi 5 qui comporte un orifice 6 centré sur l'axe de l'élément de connecteur 1.Inside this conductive housing 3 is a first cylindrical insulating body 4 closed, on the side of the face coupling F, by a wall 5 which has an orifice 6 centered on the axis of the connector element 1.

Un second corps isolant cylindrique 7 est logé à l'intérieur du premier corps isolant 4. Ce second corps isolant 7 est fermé à sa partie inférieure par une paroi 8 qui est également munie d'un orifice 9 coaxial au boítier conducteur 3.A second cylindrical insulating body 7 is housed inside of the first insulating body 4. This second insulating body 7 is closed at its lower part by a wall 8 which is also provided with an orifice 9 coaxial to the driver housing 3.

Une lame rigide 10, formant une pièce de contact fixe au sens de l'invention, s'étend depuis l'extérieur de l'élément de connecteur 1 jusqu'à la cavité intérieure du second corps isolant 7 en étant logée entre les deux corps isolants 4 et 7 dans une gorge 11 ménagée à cet effet dans le second corps isolant 7.A rigid blade 10, forming a contact piece fixed to the sense of the invention, extends from outside the element of connector 1 to the interior cavity of the second insulating body 7 in being housed between the two insulating bodies 4 and 7 in a groove 11 provided for this purpose in the second insulating body 7.

Le second corps isolant 7 comporte en outre une fente 12 dans laquelle s'engage une plaque de masse 13.The second insulating body 7 also has a slot 12 in which a ground plate 13 engages.

Au centre de l'élément de connecteur femelle 1 se trouve un conducteur central fixe 14 qui s'étend depuis la base de l'élément de connecteur et fait saillie au-delà de la paroi supérieure 5 du premier corps isolant 4, au travers de son orifice 6.In the center of the female connector element 1 is a fixed central conductor 14 which extends from the base of the element of connector and protrudes beyond the top wall 5 of the first insulating body 4, through its orifice 6.

Une douille conductrice 15, emmanchée librement autour du conducteur central 14, comporte une partie arrière en forme de collerette 16 qui se trouve à l'intérieur du corps isolant 4 et une partie frontale 17 qui se trouve à l'extérieur du corps isolant 4, et est donc accessible depuis l'extérieur de l'élément de connecteur, par la face d'accouplement de ce dernier. La douille 15 est prévue pour coulisser avec un faible jeu radial autour du conducteur central 14.A conductive sleeve 15, freely fitted around the central conductor 14, has a rear part in the form of flange 16 which is inside the insulating body 4 and a front part 17 which is located outside the insulating body 4, and is therefore accessible from outside the connector element, by the coupling face of the latter. The socket 15 is provided for slide with a small radial clearance around the central conductor 14.

Le diamètre externe de la douille 15 est légèrement inférieur au diamètre interne de l'orifice 6.The external diameter of the sleeve 15 is slightly smaller than the internal diameter of the orifice 6.

Un ressort hélicoïdal 18, logé à l'intérieur de la douille conductrice 15 et prenant appui d'une part contre la paroi intérieure de la partie frontale 17 de la douille ce qui permet de loger le ressort 18 sans accroítre la hauteur de l'élément de connecteur, d'autre part contre la paroi 8 du second corps isolant 7, repousse la douille en direction de la lame rigide 10 contre laquelle elle s'appuie par sa collerette 16.A helical spring 18, housed inside the sleeve conductive 15 and bearing on the one hand against the inner wall of the front part 17 of the socket which makes it possible to house the spring 18 without increasing the height of the connector element, on the other hand against the wall 8 of the second insulating body 7, pushes the socket in the direction of the rigid blade 10 against which it is supported by its flange 16.

Ce ressort 18 travaille uniquement en compression et ne subit aucune usure par frottement lors de l'utilisation du connecteur.This spring 18 works only in compression and does not undergoes no wear by friction when using the connector.

Comme on le voit sur la figure 1, la douille conductrice 15 ne prend appui sur la lame rigide 10 qu'en une partie périphérique limitée de sa collerette 16.As seen in Figure 1, the conductive sleeve 15 only rests on the rigid blade 10 in a peripheral part limited of its flange 16.

Ainsi, lorsque l'élément de connecteur 1 est au repos comme représenté sur la figure 1, la douille conductrice 15, qui est repoussée axialement par le ressort hélicoïdal 18 et ne prend appui sur la lame rigide 10 qu'en une partie de sa collerette 16, se positionne obliquement par rapport au conducteur central 14, selon la direction indiquée par la flèche 19, dans les limites autorisées par le jeu radial qui existe entre ledit conducteur central 14 et ladite douille 15.Thus, when the connector element 1 is at rest as shown in Figure 1, the conductive sleeve 15, which is pushed axially by the helical spring 18 and is not supported on the rigid blade 10 that in part of its flange 16, is positioned obliquely to the central conductor 14, according to the direction indicated by arrow 19, within the limits authorized by the radial clearance which exists between said central conductor 14 and said socket 15.

Ce positionnement oblique garantit un bon contact électrique entre le conducteur central 14 et la douille conductrice 15.This oblique positioning guarantees good electrical contact between the central conductor 14 and the conductive socket 15.

L'élément de connecteur complémentaire 2 comporte un boítier conducteur externe 20, un corps isolant intermédiaire 21 et un conducteur central 22.The complementary connector element 2 comprises a housing external conductor 20, an intermediate insulating body 21 and a central conductor 22.

Le conducteur central 22 de l'élément mâle 2 se situe légèrement en retrait par rapport à la face frontale du corps isolant intermédiaire 21, de sorte que, comme on le voit sur la figure 2, le corps isolant intermédiaire 21 repousse la douille conductrice 15 en s'appuyant sur sa partie frontale 17 qui est accessible depuis la face d'accouplement F de l'élément de connecteur et écarte ladite douille de la lame rigide 10 avant de réaliser le contact électrique entre le conducteur central 14 de l'élément femelle 1 et le conducteur central 22 de l'élément mâle 1.The central conductor 22 of the male element 2 is located slightly set back from the front of the insulating body intermediate 21, so that, as seen in FIG. 2, the intermediate insulating body 21 pushes back the conductive sleeve 15 in based on its front part 17 which is accessible from the face coupling F of the connector element and spreads said socket of the rigid blade 10 before making the electrical contact between the central conductor 14 of the female element 1 and the central conductor 22 of the male element 1.

La course de la douille conductrice 15 est très faible, compte-tenu des dimensions du connecteur, mais suffisante pour réaliser la commutation.The travel of the conductive sleeve 15 is very small, taking into account the dimensions of the connector, but sufficient for perform the switching.

On peut remarquer que le corps isolant intermédiaire 21, qui est cylindrique, prend appui sur toute la périphérie de la douille conductrice 15, de sorte que cette dernière est remise dans l'axe du conducteur central 14 pendant son déplacement, d'où de très faibles frottements entre la portion de guidage 17 de la douille 15 et le conducteur central 14.It can be noted that the intermediate insulating body 21, which is cylindrical, rests on the entire periphery of the sleeve conductive 15, so that the latter is returned to the axis of the central conductor 14 during its movement, hence very low friction between the guide portion 17 of the sleeve 15 and the central conductor 14.

Lorsque les deux éléments de connecteur sont accouplés, comme représenté sur la figure 4, la douille conductrice 15 est totalement escamotée à l'intérieur du premier corps isolant 4 et les deux conducteurs centraux 14 et 22, ainsi que les boítiers externes 3 et 20 dont les diamètres respectivement interne et externe se correspondent, sont électriquement reliés deux à deux.When the two connector elements are coupled, as shown in Figure 4, the conductive sleeve 15 is completely retracted inside the first insulating body 4 and the two central conductors 14 and 22, as well as the external boxes 3 and 20 whose internal and external diameters are respectively correspond, are electrically connected two by two.

Il est bien entendu que le mode de réalisation qui vient d'être décrit ne présente aucun caractère limitatif et qu'il pourra recevoir toutes modifications désirables sans sortir pour cela du cadre de l'invention.It is understood that the embodiment which comes to be described has no limiting nature and that it may receive any desirable changes without leaving the part of the invention.
