Description

PRISE POUR CIRCUIT HYPEREREQUENCEt pçseription
L'invention concerne une prise pour circuit utilisable dans le domaine des hyperfréquences permettant une transition entre lignes microbandes et une âme d'un câble coaxial.
TAKE FOR HYPEREREQUENCE CIRCUIT and pçseription
The invention relates to a socket for a circuit usable in the microwave field allowing a transition between microstrip lines and a core of a coaxial cable.

Une telle prise est adaptable par exemple a un circuit multicouche utilisable dans le domaine des hyperfréquences tel que décrit dans la demande de brevet français nO 88 05011. Such a socket is adaptable, for example, to a multilayer circuit usable in the microwave field as described in French patent application No. 88 05011.

Dans les circuits hyperfréquences, la transition d'une ligne microbande, connue sous le nom anglais 'microstrip" et réalisée sur alumine ou verre téflon ou autre support, avec un câble coaxial est obtenue au moyen d'un connecteur fixé sur une boîte métallique servant de blindage pour la fonction hyperfréquence considérée, et l'âme du câble coaxial du connecteur est soudée sur la ligne microstrip. La soudure est un moyen de liaison rigide présentant des inconvénients comme par exemple,
de provoquer un décollement de la ligne sur le circuit
lorsque des efforts sont transmis au connecteur lors de
montages ou démontages,
de n'être déssoudable qu'au risque de détruire le circuit.
In microwave circuits, the transition of a microstrip line, known under the English name "microstrip" and produced on alumina or Teflon glass or other support, with a coaxial cable is obtained by means of a connector fixed on a metal box serving shield for the microwave function considered, and the core of the coaxial cable of the connector is welded to the microstrip line. Welding is a rigid connection means having drawbacks, for example,
to cause the line to come off on the circuit
when efforts are transmitted to the connector during
assembly or disassembly,
to be unsolderable only at the risk of destroying the circuit.

L'invention a pour but d'éviter les inconvénients des prises de contact électrique connus et d'adapter au circuit utilisable dans le domaine des hyperfréquences de la demande de brevet n" 88 050111 une prise selon l'invention se caractérisant en ce que la prise comporte une pince à glissière dans laquelle sont insérées et pressées l'un contre l'autre d'une part une partie du circuit qui porte des lignes de contact et d'autre part l'âme d'un câble coaxial.  The object of the invention is to avoid the drawbacks of known electrical contact sockets and to adapt to the circuit usable in the microwave field of patent application No. 88 050111 a socket according to the invention, characterized in that the socket has a slide clamp in which are inserted and pressed one against the other on the one hand a part of the circuit which carries contact lines and on the other hand the core of a coaxial cable.

La prise hyperfréquence selon l'invention permet d'obtenir un raccordement souple de l'âme d'un câble coaxial d'un connecteur sur une ligne microstrip. Le contact est établi à l'aide d'une pince à glissière dont le mors mobile est en matière isolante. Ce mors mobile en forme de coin assure un contact par pression entre l'âme du câble coaxial du connecteur et la ligne microstrip. Le mors mobile est solidarisé au corps de la prise hyperfréquence par au moins une vis. The microwave socket according to the invention makes it possible to obtain a flexible connection of the core of a coaxial cable of a connector on a microstrip line. The contact is established using a slide clamp whose movable jaw is made of insulating material. This wedge-shaped movable jaw provides pressure contact between the core of the coaxial cable of the connector and the microstrip line. The movable jaw is secured to the body of the microwave socket by at least one screw.

Cette prise permet grâce à un dégagement du plan de masse de référence du circuit d'obtenir une bonne continuité de masse avec l'âme du câble coaxial du connecteur. Ce mode de raccordement présente l'avantage de ne pas détériorer le circuit et d'être directement solidaire du circuit. La reproductibilité de ce mode d'interconnexion est accrue par rapport à un moyen de soudure car elle ne fait pas appel directement à l'intervention humaine qualité de soudage, température de la soudure et échauffement d'une partie du circuit). This outlet makes it possible, thanks to a clearing of the reference ground plane of the circuit, to obtain good ground continuity with the core of the coaxial cable of the connector. This connection method has the advantage of not damaging the circuit and of being directly integral with the circuit. The reproducibility of this mode of interconnection is increased compared to a welding means because it does not directly call for human intervention quality of welding, temperature of the welding and heating of part of the circuit).

Dans une forme préférentielle de l'invention, la pince à glissière est composée d'une partie du corps de la prise comportant un plan incliné situé en vis-à-vis d'un épaulement, épaulement formant un mors fixe de la pince1 d'un mors mobile muni d'un plan incliné et'd'au moins une vis de déplacement, le plan incliné du mors mobile et le plan incliné du corps glissant l'une sur l'autre. Le corps de la prise sur lequel est soudé un connecteur coaxial hyperfréquence est réalisé en fonderie cuproaluminium ce qui permet d'obtenir des formes complexes pour les pièces de petites dimensions et de bonnes caractéristiques électriques. Une finition dorée contribue à garantir les caractéristiques électriques demandées et un bon état de finition. In a preferred form of the invention, the slide clamp is composed of a part of the body of the socket comprising an inclined plane located opposite a shoulder, shoulder forming a fixed jaw of the clamp1 a movable jaw provided with an inclined plane and 'at least one displacement screw, the inclined plane of the movable jaw and the inclined plane of the body sliding over one another. The body of the socket on which a microwave coaxial connector is welded is made of copper-aluminum foundry, which makes it possible to obtain complex shapes for parts of small dimensions and good electrical characteristics. A golden finish helps to guarantee the requested electrical characteristics and a good finish.

La description ci-après, le tout donné à titre d'exemple non limitatif, fera bien comprendre comment l'invention est réalisée. The description below, all given by way of nonlimiting example, will make it clear how the invention is implemented.

La figure unique I est une vue en coupe longitudinale d'une prise selon l'invention, prise montée dans un exemple d'utilisation sur un circuit multicouche hyperfréquence. The single figure I is a longitudinal section view of a socket according to the invention, socket mounted in an example of use on a multilayer microwave circuit.

La figure 1 représente en coupe une prise hyperfréquence selon l'invention, la prise 1 pincant une partie du circuit multicouche 2. FIG. 1 shows in section a microwave socket according to the invention, socket 1 pinching part of the multilayer circuit 2.

La prise 1 est constituée d'un corps 3 sensiblement parallélépipédique comportant un premier épaulement constituant un mors fixe 5 d'une pince à glissière 6, un second épaulement 4 portant une partie d'un circuit multicouche 2. En vis-à-vis du mors fixe 5 est aménagé un plan incliné 7 sur lequel se déplace un mors mobile 8 en forme de coin-possédant un plan incliné 9 et composé d'une matière isolante. Le mors mobile 8 est assujetti au corps 3 de la prise 1 par deux vis 10 s'insérant dans des trous Il taraudés du corps 3 et traversant librement le mors mobile 8. The socket 1 consists of a body 3 substantially parallelepipedal comprising a first shoulder constituting a fixed jaw 5 of a slide clamp 6, a second shoulder 4 carrying a part of a multilayer circuit 2. Opposite the fixed jaw 5 is arranged an inclined plane 7 on which moves a movable jaw 8 in the form of a wedge-having an inclined plane 9 and composed of an insulating material. The movable jaw 8 is fixed to the body 3 of the socket 1 by two screws 10 inserting into threaded holes Il of the body 3 and freely passing through the movable jaw 8.

Le plan incliné 9 du mors mobile 8 peut glisser sur le plan incliné 7 du corps, le déplacement par les vis du mors mobile engendrant le pincement d'une partie 12 du circuit multicouche 2 et d'une âme 13 d'un câble coaxial 14 d'un connecteur hyperfréquence 15. The inclined plane 9 of the movable jaw 8 can slide on the inclined plane 7 of the body, the displacement by the screws of the movable jaw causing the pinching of a part 12 of the multilayer circuit 2 and of a core 13 of a coaxial cable 14 a microwave connector 15.

Le connecteur hyperfréquence 15 de type SMA est inséré dans un lamage 16 du corps 3 puis lié audit corps 3 par une soudure 17 ou par vissage, le lamage 16 étant remplace par un taraudage. Ainsi la pince à glissière 6 connecte une ligne microstrip de la partie 12 du circuit multicouche 2 avec l'âme 13 du câble coaxial du connecteur hyperfréquence 15.  The microwave connector 15 of SMA type is inserted into a countersink 16 of the body 3 and then connected to said body 3 by a weld 17 or by screwing, the countersink 16 being replaced by a tapping. Thus the slide clamp 6 connects a microstrip line of the part 12 of the multilayer circuit 2 with the core 13 of the coaxial cable of the microwave connector 15.
