Description

La présente invention concerne un connecteur interrupteur coaxial miniature notamment pour raccorder électriquement un élément émetteur à un couple d'antennes.The present invention relates to a connector miniature coaxial switch including for electrically connecting a transmitter element to a couple of antennas.

Un connecteur interrupteur du genre visé par l'invention est décrit dans le brevet américain 5 174 775 et l'EP 0 497 704. Ce connecteur interrupteur est utilisé notamment pour raccorder un téléphone portable de voiture à l'antenne de celle-ci. Lorsque ce téléphone est utilisé dans le mode portable à l'extérieur de la voiture, il est nécessaire de déconnecter l'antenne de la voiture, de façon que le téléphone puisse fonctionner avec sa propre antenne et sa propre source de courant.A switch connector of the type targeted by the invention is described in the US patent 5 174 775 and EP 0 497 704. This switch connector is used in particular to connect a telephone car portable to the antenna thereof. When this phone is used in portable mode to outside the car it is necessary to disconnect the antenna from the car, so that the phone can operate with its own antenna and its own power source.

La gamme à fréquence radio transmise par ce type de connecteur interrupteur est comprise entre quelques centaines de MHz et 3 GHz.The radio frequency range transmitted by this type of switch connector is between a few hundreds of MHz and 3 GHz.

Le but de la présente invention est de proposer un connecteur interrupteur ou inverseur coaxial présentant une structure simple, compatible avec les impératifs de miniaturisation, facilitant le montage de surface sur une carte de circuit imprimé, tout en permettant la transmission de fréquences comprises dans la gamme ci-dessus.The purpose of the present invention is to provide a coaxial switch or inverter connector presenting a simple structure, compatible with imperatives of miniaturization, facilitating the assembly of surface on a printed circuit board while allowing the transmission of frequencies included in the range above.

L'invention vise ainsi un connecteur interrupteur coaxial miniature, notamment pour raccorder électriquement un élément émetteur à un couple d'antennes, comprenant un corps creux duquel font saillie au moins deux éléments de contact, à l'intérieur duquel est monté de façon mobile axialement un plongeur ayant, à l'une de ses extrémités, un élément de contact électrique, ce plongeur étant sollicité par des moyens de rappel vers une première position dans laquelle un contact électrique est établi entre les deux éléments de contact et ledit plongeur étant mobile contre l'action des moyens de rappel vers une seconde position dans laquelle l'élément de contact électrique est en contact électrique avec l'un des deux éléments de contact et ces derniers sont isolés électriquement l'un de l'autre, caractérisé en ce que les deux éléments de contact sont des lames de contact situées dans un même plan et permettent le montage du connecteur à la surface d'un circuit imprimé.The invention thus relates to a connector miniature coaxial switch, including for electrically connecting a transmitter element to a pair of antennas, comprising a hollow body of which protrusion at least two contact elements, inside from which a plunger is axially movable having, at one of its ends, a contact element electric, this plunger being stressed by means to a first position in which a electrical contact is established between the two elements of contact and said plunger being movable against the action means for returning to a second position in which the electrical contact element is in contact electric with one of the two contact elements and these the latter are electrically isolated from each other, characterized in that the two contact elements are contact blades located in the same plane and allow the connector to be mounted on the surface of a printed circuit board.

Le plongeur axial déplace ainsi simultanément l'élément de contact en bout destiné par exemple à être relié à une antenne de voiture, entre une position en saillie et une position effacée, et établit le contact soit avec l'une des lames de contact ou avec les deux lames.The axial plunger thus moves simultaneously the end contact element intended for example to be connected to a car antenna, between a position in protrusion and a cleared position, and establishes contact either with one of the contact blades or with both blades.

Une telle construction est par conséquent simple à réaliser et à miniaturiser de façon à pouvoir la monter sur une carte de circuit imprimé.Such a construction is therefore simple to realize and miniaturize so that it can mount on a printed circuit board.

Selon une version avantageuse de l'invention, les parties des lames de contact faisant saillie hors du corps creux sont situées sans un plan perpendiculaire à l'axe du plongeur.According to an advantageous version of the invention, the parts of the contact blades projecting out of the hollow bodies are located without a plane perpendicular to the axis of the plunger.

Une telle disposition facilite le montage de surface du connecteur interrupteur.Such an arrangement facilitates the mounting of switch connector surface.

Le connecteur interrupteur ou inverseur comporte avantageusement un boítier extérieur en matière conductrice, par exemple en métal. De préférence, il comporte une lame de masse découpée dans ledit boítier, située dans le plan desdites parties saillantes des lames de contact.The switch or reverse connector has advantageously an external casing in material conductive, for example made of metal. Preferably, it includes a ground blade cut out from said housing, located in the plane of said projecting parts of contact blades.

Cette disposition facilite également le montage de surface. This arrangement also facilitates mounting of surface.

Dans la réalisation des figures 1 à 3, le connecteur interrupteur coaxial miniature à montage de surface, notamment pour raccorder électriquement un élément émetteur à une antenne, comprend un corps creux cylindrique 1 duquel font saillie deux lames de contact 2, 3 et une ou deux lames de masse 4, 4a, permettant le montage de surface.In the embodiment of Figures 1 to 3, the miniature coaxial switch connector surface, especially for electrically connecting a transmitting element to an antenna, includes a hollow body cylindrical 1 from which two contact blades protrude 2, 3 and one or two ground blades 4, 4a, allowing the surface mounting.

A l'intérieur du corps creux 1 est monté de façon mobile axialement un plongeur 5 en matière électriquement isolante portant à l'une de ses extrémités un élément de contact électrique en bout 6.Inside the hollow body 1 is mounted axially movable a plunger 5 in material electrically insulating bearing to one of its ends an electrical contact element at the end 6.

Le plongeur 5 est sollicité par des moyens de rappel 8 vers une première position (celle représentée sur la figure 1), dans laquelle l'élément de contact en bout 6 fait saillie à une extrémité 7 du corps creux 1 et un contact électrique est établi entre les deux lames de contact 2 et 3.The plunger 5 is stressed by means of reminder 8 to a first position (the one shown in FIG. 1), in which the contact element in tip 6 protrudes at one end 7 of the hollow body 1 and an electrical contact is established between the two blades contact 2 and 3.

D'autre part, le plongeur 5 est mobile contre l'action des moyens de rappel 8 vers une seconde position (celle représentée à la figure 4), dans laquelle l'élément de contact électrique en bout 6 est effacé de l'extrémité 7 du corps creux 1, est en contact électrique avec l'une 2 des deux lames de contact et les deux lames 2, 3 sont isolées électriquement l'une de l'autre.On the other hand, the plunger 5 is movable against the action of the return means 8 towards a second position (as shown in Figure 4), in which the end electrical contact element 6 is erased from the end 7 of the hollow body 1, is in contact electric with one of the two contact blades and the two blades 2, 3 are electrically insulated one of the other.

La lame de contact 2 est par exemple reliée à l'émetteur haute fréquence d'un téléphone portable de voiture. Le contact en bout 5 est dans cet exemple, destiné à être connecté avec une antenne de la voiture. L'autre lame de contact 3 est reliée à l'antenne appartenant au téléphone portable.The contact blade 2 is for example connected to the high frequency transmitter of a cell phone from car. The end contact 5 is in this example, intended to be connected with a car antenna. The other contact blade 3 is connected to the antenna belonging to the cell phone.

La figure 3 montre que les parties des lames de contact 2, 3 faisant saillie hors du corps creux 1 sont situées dans un plan perpendiculaire à l'axe X-X' du plongeur 5.Figure 3 shows that the parts of the blades contact 2, 3 protruding from the hollow body 1 are located in a plane perpendicular to the axis XX 'of the diver 5.

Le connecteur interrupteur comporte un boítier extérieur 9 en matière conductrice telle que du métal. Ce boítier 9 comporte une ou deux lames de masse 4, 4a (voir figure 2) découpées dans le boítier, situées dans le plan desdites parties saillantes des lames de contact 2, 3 (voir figure 3).The switch connector has a housing exterior 9 of conductive material such as metal. This housing 9 comprises one or two ground blades 4, 4a (see figure 2) cut out of the case, located in the plane of said projecting parts of the contact blades 2, 3 (see Figure 3).

L'élément de contact en bout 6 fait saillie, dans ladite première position, dans une cavité 10 pratiquée, à l'une des extrémités du corps creux 1, dans une matière électriquement isolante 11 garnissant l'intérieur du corps creux 1.The end contact element 6 projects, in said first position, in a cavity 10 made, at one end of the hollow body 1, in an electrically insulating material 11 filling inside the hollow body 1.

Par ailleurs, le plongeur 5 comporte à l'opposé de l'élément de contact en bout 6 un plateau 12 perpendiculaire à l'axe X-X' du plongeur 5 en appui par l'une 12a de ses faces sur un ressort de rappel 8 en butée contre le fond 13 du corps creux 1. L'autre face du plateau 12 comporte un élément électriquement conducteur 14 venant, dans ladite première position du plongeur 5 établir un contact électrique avec des parties des lames de contact 2, 3 situées dans un plan parallèle au plateau 12.Furthermore, the plunger 5 has, on the opposite of the contact element at the end 6 a plate 12 perpendicular to the axis XX 'of the plunger 5 in support by one 12a of its faces on a return spring 8 in abutment against the bottom 13 of the hollow body 1. The other face of the plate 12 has an electrically element conductor 14 coming, in said first position of the diver 5 establish electrical contact with parts of the contact blades 2, 3 located in a plane parallel to plate 12.

Dans l'exemple représenté, les parties ci-dessus des lames de contact 2, 3 sont situées dans le même plan que les parties de ces lames qui font saillie hors du corps creux 1.In the example shown, the above parts contact blades 2, 3 are located in the same plane that the parts of these blades that protrude out of the hollow body 1.

D'autre part, l'une 2 des deux lames de contact 2, 3 est prolongée au-delà de ladite partie située dans un plan parallèle au plateau 12, par une partie 2a s'écartant du plateau 12 et dirigée vers l'élément de contact en bout 6 du plongeur 5. Cette partie 2a de la lame 2 peut venir en contact avec l'élément de contact en bout 6, lorsque le plongeur 5 est dans la seconde position, représentée sur la figure 4.On the other hand, one 2 of the two contact blades 2, 3 is extended beyond said part located in a plane parallel to the plate 12, by a part 2a moving away from the plate 12 and directed towards the element of end contact 6 of the plunger 5. This part 2a of the blade 2 can come into contact with the contact element at the end 6, when the plunger 5 is in the second position, shown in Figure 4.

Dans l'exemple représenté sur les figures 1 à 5, la partie 2a de la lame 2 dirigée vers l'élément de contact en bout 6 est un manchon coaxial au plongeur 5 et de diamètre supérieur à élément de contact en bout 6. Ce manchon 2a présente (voir figures 2 et 5) deux languettes élastiques 15, 16 découpées dans le manchon et dont les extrémités 15a, 16a adjacentes à l'élément de contact en bout 6 sont rapprochées de l'axe X-X' du plongeur 5. Les extrémités 15a, 16a des languettes 15, 16 peuvent ainsi venir en contact avec l'élément de contact en bout 6 lorsque le plongeur 5 est dans la seconde position représentée sur la figure 4.In the example shown in Figures 1 to 5, the part 2a of the blade 2 directed towards the element of end contact 6 is a sleeve coaxial with the plunger 5 and of greater diameter than end contact element 6. This sleeve 2a has (see Figures 2 and 5) two elastic tabs 15, 16 cut from the sleeve and whose ends 15a, 16a adjacent to the element contact tip 6 are close to the axis XX 'of the plunger 5. The ends 15a, 16a of the tongues 15, 16 can thus come into contact with the element of end contact 6 when the plunger 5 is in the second position shown in Figure 4.

La figure 5 représente la forme détaillée de chaque pièce du connecteur interrupteur.Figure 5 shows the detailed form of each piece of the switch connector.

On voit en particulier sur cette figure,

  • que le garnissage intérieur isolant est en deux parties 11 et 11a superposées;
  • que le garnissage isolant supérieur comporte des tétons 11b pouvant s'engager dans des trous 2c pratiqués dans les lames 2 et 3 et dans des trous 11b ménagés sur le bord supérieur du garnissage inférieur 11a; ce qui permet d'obtenir un excellent positionnement des lames 2 et 3;
  • que le boítier 9 comporte des pattes 20 dont les extrémités 20a sont repliées sous le fond du bloc isolant 11a.
We see in particular in this figure,
  • that the insulating interior lining is in two parts 11 and 11a superimposed;
  • that the upper insulating lining comprises pins 11b which can engage in holes 2c made in the blades 2 and 3 and in holes 11b formed on the upper edge of the lower lining 11a; which provides excellent positioning of the blades 2 and 3;
  • that the housing 9 has tabs 20 whose ends 20a are folded under the bottom of the insulating block 11a.

Les figures 1 et 4 montrent également que le garnissage intérieur isolant du corps creux 1 est en deux parties 11, 11a s'appuyant l'une sur l'autre suivant le plan dans lequel s'étendent les deux lames de contact 2, 3. La partie 11 du garnissage isolant située à l'opposé du plateau 12 du plongeur 12 forme dans le plan ci-dessus deux épaulements 21 parallèles au plateau 12 contre lesquels s'appuient les deux lames de contact 2, 3.Figures 1 and 4 also show that the insulating interior lining of the hollow body 1 is in two parts 11, 11a resting on each other along the plane in which the two blades of contact 2, 3. Part 11 of the insulating lining located opposite the plate 12 of the plunger 12 forms in the above plan two shoulders 21 parallel to the plate 12 against which the two blades of contact 2, 3.

Dans la variante représentée sur la figure 6, la partie de la lame 2 dirigée vers l'élément de contact en bout 6 comporte à son extrémité une partie en forme de rondelle 22. Dans l'ouverture 22a de cette rondelle 22 est engagée la partie 5a du plongeur 5 située entre le plateau 12 et l'élément de contact en bout 6. La position de la partie en forme de rondelle 22, est telle qu'elle puisse venir en contact avec l'élément de contact en bout 6, lorsque le plongeur est dans la seconde position, c'est-à-dire lorsque l'élément 6 est effacé.In the variant shown in Figure 6, the part of the blade 2 directed towards the contact element in end 6 has at its end a part in the form of washer 22. In the opening 22a of this washer 22 is engaged part 5a of the plunger 5 located between the plate 12 and the contact element at the end 6. The position of the washer-shaped part 22, is such that she can come into contact with the element of end contact 6, when the plunger is in the second position, i.e. when element 6 is erased.

Par ailleurs, la pièce conductrice 14 pourrait être circulaire ce qui éviterait de devoir la maintenir en rotation.Furthermore, the conductive part 14 could be circular which would avoid having to maintain it in rotation.

Le connecteur interrupteur que l'on vient de décrire peut servir dans une installation de téléphone de voiture, à relier l'émetteur radio à une antenne externe. La prise de cette antenne externe comporte une fiche coaxiale dont le contact central vient en contact avec l'élément de contact 6. The switch connector that we just describe can be used in a telephone installation car, to connect the radio transmitter to an antenna external. The socket of this external antenna has a coaxial plug whose central contact comes into contact with the contact element 6.

En l'absence de cette antenne, l'élément de contact 6 fait saillie dans la cavité 10 et les extrémités des lames de contact 2, 3 sont en contact les unes avec les autres, comme indiqué sur la figure 1. Dans ce cas, le téléphone fonctionne avec sa propre antenne et peut être utilisé hors du véhicule.In the absence of this antenna, the element of contact 6 protrudes into cavity 10 and the ends of the contact blades 2, 3 are in contact with with each other, as shown in Figure 1. In this case, the phone works with its own antenna and can be used outside the vehicle.

Lorsque l'antenne est connectée, la broche centrale de celle-ci vient en contact avec l'élément de contact 6 et pousse celui-ci vers l'intérieur du corps creux 1. Le plateau 12 s'écarte alors des lames de contact 2, 3. En fin de course, l'élément de contact en bout 6 vient en contact avec les lamelles 15, 16 de la lame de contact 2 en établissant ainsi une liaison électrique entre cette dernière et l'élément de contact en bout 6.When the antenna is connected, the pin central of it comes into contact with the element of contact 6 and push it towards the inside of the body hollow 1. The plate 12 then moves away from the blades of contact 2, 3. At the end of the stroke, the contact element in tip 6 comes into contact with the lamellae 15, 16 of the contact blade 2 thereby establishing a connection electric between the latter and the contact element at the end 6.

A titre d'exemple, le connecteur interrupteur conforme à l'invention a un diamètre de l'ordre de 6 mm. Ses lames saillantes 2, 3, 4 situées dans un même plan facilitent son montage suivant l'axe X-X' du connecteur sur une carte de circuit imprimé.For example, the switch connector according to the invention has a diameter of the order of 6 mm. Its protruding blades 2, 3, 4 located in the same plane facilitate its assembly along the X-X 'axis of the connector on a printed circuit board.

Bien entendu, dans le connecteur interrupteur que l'on vient de décrire à titre d'exemple, l'élément de contact 6 pourrait être toujours alimenté c'est-à-dire toujours en liaison électrique avec la lame de contact 2. Ce résultat peut être obtenu en augmentant la longueur de l'élément de contact 6 de façon que dans la position de la figure 1, il soit en contact avec la partie 2a.Of course, in the switch connector that we have just described by way of example, the element contact 6 could still be energized i.e. always in electrical connection with the blade contact 2. This can be achieved by increasing the length of the contact element 6 so that in the position of Figure 1, it is in contact with the part 2a.

Dans la variante représentée sur la figure 7, le plongeur 5 porte un élément de contact en bout 5a qui est nettement en retrait par rapport à l'extrémité 7 du corps creux 1.In the variant shown in Figure 7, the plunger 5 carries an end contact element 5a which is clearly set back from the end 7 of the hollow body 1.

Comme sur la figure 1, l'une 2 des deux lames de contact 2, 3 est prolongée par une partie 2a s'écartant du plateau 12 et dirigée vers le contact en bout 5a du plongeur 5. De ce fait, lorsqu'une broche de connexion externe 6a est enfoncée dans le corps creux 1, celle-ci est d'abord en contact électrique avec la partie 2a dirigée vers l'extrémité et allant au-delà de l'extrémité de contact en bout 5a du plongeur, puis pousse sur l'extrémité de contact 5a du plongeur 5.As in Figure 1, one 2 of the two blades of contact 2, 3 is extended by a part 2a deviating of the plate 12 and directed towards the end contact 5a of the plunger 5. As a result, when a connecting pin external 6a is pressed into the hollow body 1, the latter is first in electrical contact with part 2a directed towards the end and going beyond the tip contact end 5a of the plunger, then pushes on the contact end 5a of the plunger 5.

Dans cette variante de réalisation, la partie 2a de la lame dirigée vers l'élément de contact en bout 5a est un manchon coaxial au plongeur 5 et de diamètre équivalent à celui-ci.In this alternative embodiment, part 2a of the blade directed towards the end contact element 5a is a sleeve coaxial to the plunger 5 and of diameter equivalent to this one.

Ce manchon 2a présente des languettes élastiques venant en contact avec la broche de connexion extérieure 6a avant que le plongeur 5 soit dans ladite seconde position.This sleeve 2a has elastic tabs coming into contact with the external connection pin 6a before the plunger 5 is in said second position.
