Plus précisément, lorsque l'appareil est utilisée comme appareil portatif en dehors d'une voiture, le circuit de l'appareil est connecté à l'antenne externe par l'intermédiaire d'un contact interne. Lorsque l'appareil est mis en position dans une voiture, il est placé sur un connecteur incorporé à la voiture et relié à une antenne externe, et ce connecteur déplace un ensemble mobile qui d'une part assure la connexion entre l'antenne externe et le circuit interne de l'appareil et d'autre part la déconnexion du second contact relié à l'antenne interne de l'appareil.The present invention relates to a connector-switch component. intended for automatic switching above when connecting and disconnecting the device to an external antenna. More specifically, when the device is used as a portable device outside of a car, the device circuit is connected to the external antenna via an internal contact. When the device is positioned in a car, it is placed on a connector incorporated in the car and connected to an external antenna, and this connector moves an assembly mobile which on the one hand ensures the connection between the antenna external and internal circuitry of the device and secondly the disconnection of the second contact connected to the internal antenna of the device.

The latter ends with a rounded head 30 protruding slightly inside the body cavity, on the side of it. Near the second contact 28 and more precisely of its head 30 placed inside the body, this one has an enlarged cavity 32 whose role is described below.

    Les éléments décrits jusqu'à présent sont fixes les uns par rapport aux autres et sont destinés à être fixés au corps d'un appareil. Le composant comporte en outre un ensemble mobile 34.The elements described so far are fixed the relative to each other and are intended to be fixed to the body of a device. The component also includes a mobile assembly 34.

    L'ensemble mobile 34 comprend un organe conducteur 36 analogue à une tige allongée. Du côté tourné vers le premier contact 16, l'organe conducteur 36 a un trou longitudinal 38 emmanché sur la broche 18 du premier contact. On a représenté une fente formée dans ce trou afin que la broche 18 soit légèrement serrée par l'organe conducteur 36 tout en pouvant coulisser dans le trou 38. A l'extrémité de l'organe conducteur tournée vers la broche 18, celui-ci comporte une patte 40 formant un contact mobile. Dans la position représentée sur la figure 1, on note que ce contact mobile 40 est placé contre la tête 30 du second contact fixe 28. Au contraire, dans la position de la figure 2, ce contact 40 est distant de la tête de contact 30 et se trouve au milieu de la cavité 32 qui remplit alors pleinement sa fonction d'adaptation d'impédance.The mobile assembly 34 includes a conductive member 36 analogous to an elongated rod. On the side facing the first contact 16, the conductive member 36 has a longitudinal hole 38 fitted on pin 18 of the first contact. We have shown a slit formed in this hole so that the pin 18 is slightly tightened by the conductive member 36 while able to slide in the hole 38. At the end of the member conductor turned towards pin 18, this comprises a tab 40 forming a movable contact. In the position shown in Figure 1, we note that this mobile contact 40 is placed against the head 30 of the second fixed contact 28. At on the contrary, in the position of FIG. 2, this contact 40 is distant from the contact head 30 and is in the middle of the cavity 32 which then fully fulfills its function impedance matching.

    L'autre extrémité de l'organe conducteur 36 de l'ensemble mobile 34 a un élément permettant la connexion avec un organe connecteur externe. Dans le mode de réalisation représenté sur les figures 1 et 2, cet élément de connexion est formé par un trou 42 analogue au trou 38 et destiné à coopérer avec une broche. Cependant, il s'agit d'un simple exemple, sous forme d'un élément femelle, mais d'autres éléments femelles ou mâles peuvent le remplacer.The other end of the conductive member 36 of the mobile assembly 34 has an element allowing the connection with an external connector member. In the mode of embodiment shown in Figures 1 and 2, this element connection is formed by a hole 42 similar to the hole 38 and intended to cooperate with a spindle. However, this is of a simple example, as a female element, but other female or male elements can replace it.

    L'organe connecteur 36 de l'ensemble mobile est entouré d'un troisième organe isolant 44. Celui-ci a une forme cylindrique de révolution. Cependant, dans sa partie tournée vers le premier contact fixe 16, il est découpé et a une forme de demi-cylindre comme indiqué par la référence 44 sur les figures 3 et 5. L'organe isolant 44 entoure l'organe 36 pratiquement sur toute sa longueur, sauf au niveau d'une partie dégagée destinée à loger le partie hémicylindrique 22 du premier organe isolant 14.The connector member 36 of the mobile assembly is surrounded by a third insulating member 44. This has a cylindrical shape of revolution. However, in its part facing the first fixed contact 16, it is cut and has the shape of a half cylinder as indicated by the reference 44 in FIGS. 3 and 5. The insulating member 44 surrounds member 36 practically over its entire length, except at level of a clear part intended to house the part semi-cylindrical 22 of the first insulating organ 14.

    L'ensemble mobile comporte en outre un organe conducteur de masse représenté par un manchon 48 de forme cylindrique. A l'extrémité externe, le manchon 48 porte une collerette 50 et son corps cylindrique est prolongé, vers le premier contact 16, par des bras 52, mieux représentés sur la figure 4.The mobile assembly further includes a member ground conductor represented by a shaped sleeve 48 cylindrical. At the outer end, the sleeve 48 carries a flange 50 and its cylindrical body is extended, towards the first contact 16, by arms 52, better represented on Figure 4.

    Enfin, un ressort 54 constitue un organe de rappel destiné à repousser l'ensemble mobile 34 vers l'extérieur du corps 10. A cet effet, le ressort 54 est en appui d'un côté contre la collerette 50 du manchon conducteur de masse et, de l'autre côté, contre un épaulement 56 du corps. Finally, a spring 54 constitutes a return member intended to push the mobile assembly 34 towards the outside of the body 10. For this purpose, the spring 54 is supported on one side against the flange 50 of the earth conductive sleeve and, on the other side, against a shoulder 56 of the body.

    On décrit maintenant le fonctionnement du composant connecteur-commutateur des figures 1 et 2 dans son application à un radiotéléphone de voiture de type portatif.We now describe the operation of the component connector-switch of Figures 1 and 2 in sound application to a portable type car radiotelephone.

    Lorsque le composant est monté dans un radiotéléphone portatif de voiture, le corps 10 est fixé dans le boítier du radiotéléphone et, étant donné qu'il est conducteur, il est mis à la masse par une patte 58. Le premier contact 16 est relié aux circuits électroniques de l'appareil. Le second contact fixe 28 est relié à l'antenne interne du radiotéléphone. Lorsque le radiotéléphone n'est pas installé à l'intérieur d'une voiture, le composant à la position de la figure 1. Plus précisément, le ressort 54 repousse le manchon 48 et, en conséquence, l'ensemble mobile 34 vers la position de la figure 1 dans laquelle les doigts élastiques et conducteurs du manchon 52 sont à distance de la tête 30 du second contact fixe. Par contre, la patte formant le contact mobile 40 de l'organe conducteur 36 est placée contre la tête 30 du second contact fixe 28. Comme l'organe conducteur 36 est par ailleurs en permanence relié au premier contact fixe 16 par coulissement du trou 38 sur la broche 18, les deux contacts fixes 16 et 28 sont reliés. En conséquence, l'antenne interne au radiotéléphone est reliée aux circuits électroniques de celui-ci. Le radiotéléphone peut donc être utilisé comme poste portatif.When the component is mounted in a radiotelephone portable car, the body 10 is fixed in the housing of the radiotelephone and, since it is a conductor, it is grounded by a lug 58. The first contact 16 is connected to the electronic circuits of the device. The second fixed contact 28 is connected to the internal antenna of the radiotelephone. When the radiotelephone is not installed inside a car, the component at the position of Figure 1. More specifically, the spring 54 pushes the sleeve 48 and, consequently, the movable assembly 34 towards the position of Figure 1 in which the elastic fingers and conductors of the sleeve 52 are at a distance from the head 30 second fixed contact. On the other hand, the tab forming the movable contact 40 of the conductive member 36 is placed against the head 30 of the second fixed contact 28. Like the member conductor 36 is also permanently connected to the first fixed contact 16 by sliding the hole 38 on the pin 18, the two fixed contacts 16 and 28 are connected. In consequence, the internal radiotelephone antenna is connected to its electronic circuits. The radiotelephone can therefore be used as a portable station.

    Lorsque le radiotéléphone doit être utilisé à l'intérieur d'une voiture, il est logé dans une cavité prévue à cet effet. Le corps du radiotéléphone est alors guidé de manière que le composant de la figure 1 vienne coopérer avec un organe connecteur complémentaire qui, dans le cas du composant particulier représenté sur les figures 1 et 2, comporte une broche entourée par une cuvette de masse. Lors de l'enfoncement du radiotéléphone, cette broche pénètre dans le trou 42 puis repousse l'organe mobile 34 alors que l'extrémité du corps 10 vient se loger dans la cuvette du connecteur complémentaire. L'ensemble mobile se déplace alors vers la position représentée sur la figure 2. Dans cette position, le ressort 54 a été comprimé par déplacement de la collerette 50 vers la gauche sur la figure 2. En conséquence, le contact mobile 40 s'est écarté de la tête de contact 30. Le premier contact fixe 16 n'est donc plus relié au second contact fixe 28. Par contre, il est relié à la broche qui a été introduite dans le trou 42 et il est donc relié à une antenne externe. Par ailleurs, le déplacement de l'organe mobile 34 a provoqué le passage d'un doigt conducteur 52 sur la tête de contact 30, alors que l'autre doigt conducteur 52, par coulissement dans la rainure 24 du premier organe isolant 14, assure le positionnement en rotation du manchon 48. En conséquence, le second contact fixe 28 est alors au contact du manchon 48 qui est lui-même mis à la masse par contact avec le corps, en particulier par l'intermédiaire du ressort 54 et du doigt élastique 52 de guidage. La cavité 32 assure une adaptation d'impédance telle que le fonctionnement avec l'antenne externe n'est pas perturbé et, simultanément, l'antenne interne est reliée à la masse et ne perturbe pas la communication.When the radiotelephone is to be used at inside a car it is housed in a cavity provided for this purpose. The body of the radiotelephone is then guided so that the component of figure 1 comes cooperate with a complementary connector member which, in the case of the particular component shown in the figures 1 and 2, has a pin surrounded by a bowl mass. When the radiotelephone is inserted, this pin enters the hole 42 then pushes the movable member 34 while the end of the body 10 is housed in the additional connector cup. The mobile assembly is then moves to the position shown in Figure 2. In this position, the spring 54 has been compressed by movement of the flange 50 to the left in the figure 2. Consequently, the movable contact 40 has moved away from the contact head 30. The first fixed contact 16 is therefore no longer connected to the second fixed contact 28. However, it is connected to the pin that was introduced into hole 42 and there is therefore connected to an external antenna. In addition, the movement of the movable member 34 has caused the passage of a conductive finger 52 on the contact head 30, while the other conductive finger 52, by sliding in the groove 24 of the first insulating member 14, ensures the rotational positioning of the sleeve 48. Consequently, the second fixed contact 28 is then in contact with the sleeve 48 which is itself grounded by contact with the body, in particular via the spring 54 and the finger elastic guide 52. The cavity 32 ensures an adaptation impedance such as operation with the antenna is not disturbed and, simultaneously, the antenna internal is connected to ground and does not disturb the communication.

    Dans un mode de réalisation, le corps 10 est formé d'un alliage léger à base d'aluminium et les contacts fixes 16 et 28, l'organe conducteur 36 et le manchon 48 sont formés de bronze ou béryllium. Le ressort 54 est formé d'acier. Les isolants 14, 26 et 44 sont avantageusement formés de "Nylon".In one embodiment, the body 10 is formed a light alloy based on aluminum and the fixed contacts 16 and 28, the conductive member 36 and the sleeve 48 are formed of bronze or beryllium. Spring 54 is formed of steel. Insulators 14, 26 and 44 are advantageously formed of "Nylon".

    Dans un mode de réalisation, la largeur totale du composant des figures 1 et 2 est de 4 mm, sa longueur de 11 mm et la course de l'organe mobile 34 est de 0,9 mm. Il s'agit donc d'un composant miniature qui assure cependant des fonctions élaborées. En effet, il permet la commutation entre une première position dans laquelle les deux contacts fixes sont connectés, et une seconde position dans laquelle un contact fixe est connecté à un contact externe et l'autre contact fixe est à la masse. Il remplit donc à la fois des fonctions de connecteur, de commutateur et d'interrupteur.In one embodiment, the total width of the component of Figures 1 and 2 is 4 mm, its length 11 mm and the stroke of the movable member 34 is 0.9 mm. he it is therefore a miniature component which, however, ensures sophisticated functions. Indeed, it allows switching between a first position in which the two contacts fixed are connected, and a second position in which one fixed contact is connected to an external contact and the other fixed contact is grounded. It therefore fulfills both connector, switch and switch functions.

    On a indiqué que l'ensemble mobile était guidé en translation, de manière qu'il ne puisse pas tourner, par coopération d'une partie hémicylindrique 22 du premier organe isolant 14 et d'une partie hémicylindrique de l'isolant 44 de l'ensemble mobile 34. Bien entendu, de nombreux autres dispositifs de guidage peuvent être utilisés. En effet, bien que, dans ce mode de réalisation, le guidage soit réalisé entre les deux isolants, il peut être réalisé entre un isolant et l'organe conducteur mobile 36 ou entre l'organe conducteur mobile et le premier contact. En outre, bien qu'on ait indiqué que le guidage du manchon 48 était assuré par déplacement d'un doigt 52 dans une rainure 24 de l'isolant, d'autres dispositions sont possibles, par exemple le coulissement d'un ergot solidaire du manchon 48 dans une gorge du corps 10.It was stated that the mobile assembly was guided in translation, so that it cannot rotate, by cooperation of a semi-cylindrical part 22 of the first insulating organ 14 and a semi-cylindrical part of the insulator 44 of the mobile assembly 34. Of course, many other guiding devices can be used. Indeed, although in this embodiment, guiding is carried out between the two insulators, it can be made between an insulator and the movable conductive member 36 or between the movable conductive member and the first contact. In addition, although it has been reported that the guidance of the sleeve 48 was secured by moving a finger 52 in a groove 24 of the insulation, other provisions are possible, for example the sliding of an integral lug of the sleeve 48 in a groove in the body 10.

    On a indiqué que l'organe fixe 16 comportait une broche coopérant avec un élément femelle représenté par le trou 38 de l'organe conducteur 36. Toute autre disposition peut être utilisée, du moment qu'elle assure la conservation de la coopération du contact fixe 16 et de l'organe conducteur 36. En particulier, la disposition mâle-femelle peut être remplacée par une disposition femelle-mâle.It has been indicated that the fixed member 16 comprises a spindle cooperating with a female element represented by the hole 38 of the conductive member 36. Any other provision can be used, as long as it ensures conservation of the cooperation of the fixed contact 16 and of the organ conductor 36. In particular, the male-female arrangement can be replaced by a female-male arrangement.

    Bien qu'on ait indiqué que le dispositif de rappel était constitué par un ressort hélicoïdal placé entre le corps et le manchon conducteur 48, de nombreux autres dispositifs de rappel peuvent être utilisés, notamment des dispositifs qui peuvent travailler non à la compression mais à la traction.Although it was stated that the reminder consisted of a coil spring placed between the body and conductive sleeve 48, many others recall devices can be used, including devices that can work not in compression but tensile.

    Enfin, bien qu'on ait indiqué que la partie de connecteur formée à l'extrémité droite (figures 1 et 2) du composant était de type femelle, d'autres types d'élément connecteur peuvent être utilisés. Il suffit que la partie de connecteur formée par le composant puisse venir coopérer avec une partie complémentaire par déplacement dans la direction longitudinale du composant, c'est-à-dire la direction de déplacement de l'ensemble mobile 34.Finally, although it has been indicated that the part of connector formed at the right end (Figures 1 and 2) of the component was female, other element types connector can be used. It is enough that the part of connector formed by the component can come to cooperate with an additional part by displacement in the longitudinal direction of the component, i.e. the direction of movement of the mobile assembly 34.
