Description
La présente invention est relative à un relais inverseur hyperfréquence du type comportant trois contacts coaxiaux dont un contact central, deux lames de contact rigides susceptibles de venir en appui chacune en alternance sur le contact central et l'une des deux autres contacts coaxiaux, l'autre lame venant alors en appui contre un plan de masse, chacune desdites lames de contact étant solidaire d'une poussoir isolant et chacun des poussoirs étant repoussé en translation par une lameressort sous l'effet d'une palette magnétique à deux branches susceptible de basculer autour d'un axe central, notamment sous l'action d'un moteur électromagnétique.The present invention relates to a microwave reversing relay of the type comprising three coaxial contacts including a central contact, two rigid contact blades capable of coming to bear each alternately on the central contact and one of the two other coaxial contacts, the another blade then coming to bear against a ground plane, each of said contact blades being integral with an insulating plunger and each of the plungers being pushed back in translation by a spring spring under the effect of a magnetic pallet with two branches capable of tilting around a central axis, in particular under the action of an electromagnetic motor.
La moteur électromagnétique, par exemple de type monostable, comprend avantageusement une bobine d'induction dont le noyau magnétique est disposé à l'aplomb de l'axe de pivotement de la palette, et une colonne en matériau magnétique dont une extrémité se trouve en regard d'une des branches de la palette et dont l'autre extrémité est reliée par une plaque magnétique au noyau de la bobine. Avantageusement le moteur peut comprendre un aimant permanent solidaire d'une masse polaire disposée en regard de l'autre branche de la palette, une plaque magnétique de liaison assurant un passage de flux magnétique de l'aimant dans le noyau de la bobine et dans la colonne en regard de la première branche de la palette, le flux créé par l'aimant dans le noyau de la bobine étant de sens opposé au flux créé dans le noyau par l'excitation électrique de la bobine d'induction.The electromagnetic motor, for example of the monostable type, advantageously comprises an induction coil, the magnetic core of which is arranged directly above the pivot axis of the pallet, and a column of magnetic material, one end of which is opposite. one of the branches of the pallet and the other end of which is connected by a magnetic plate to the core of the coil. Advantageously, the motor can comprise a permanent magnet secured to a polar mass placed opposite the other branch of the pallet, a magnetic connecting plate ensuring a passage of magnetic flux from the magnet into the core of the coil and in the column opposite the first branch of the pallet, the flux created by the magnet in the core of the coil being in the opposite direction to the flux created in the core by the electrical excitation of the induction coil.
Pour assurer un bon fonctionnement de tels relais inverseurs, il est nécessaire d'obtenir la qualité le meilleure possible de transmission de l'entrée vers la voie commutée et une très haute isolation de l'entrée vers la voie non commutée.To ensure proper operation of such change-over relays, it is necessary to obtain the best possible quality of transmission from the input to the switched channel and very high isolation of the input to the non-switched channel.
On prévoit habituellement (US-A-3681 719, US-A-3 739 306) à cet effet des ressorts de rappel contre la force desquels les poussoirs sont repoussés par la palette et qui servent à plaquer les lames de contact solidaires des poussoirs contre le plan de masse.There are usually provided (US-A-3681 719, US-A-3 739 306) for this purpose return springs against the force of which the pushers are pushed back by the pallet and which serve to press the contact blades integral with the pushers against the ground plan.
Les relais inverseurs coaxiaux hyperfréquence du type mentionné présentent l'inconvénient de nécessiter une énergie importante pour assurer une pression suffisante d'appui de la lame de contact associée à la voie commutée avec le contact central et le contact de la voie commutée, afin d'obtenir une bonne transmission, et une pression suffisante d'appui de la lame de contact associée à la voie non commutée avec le plan de masse afin d'assurer une bonne isolation. Cette dernière pression d'appui dépend en effet de la force de rappel des ressorts sur lesquels s'appuient les poussoirs, force de rappel que doit au contraire vaincre le poussoir lors de son déplacement sous l'effet de l'actionnement du moteur de relais.Coaxial microwave reversing relays of the type mentioned have the drawback of requiring significant energy to ensure sufficient contact pressure of the contact blade associated with the switched channel with the central contact and the contact of the switched channel, in order to obtain good transmission and sufficient contact pressure of the contact blade associated with the non-switched track with the ground plane in order to ensure good insulation. This last pressing pressure in fact depends on the restoring force of the springs on which the pushers are supported, restoring force which, on the contrary, must be overcome by the pushbutton during its movement under the effect of the actuation of the relay motor. .
La présente invention se propose de réaliser un relais inverseur coaxial hyperfréquence de conception simple sur le plan mécanique, évitant l'utilisation de ressorts de rappel et ne nécessitant qu'une consommation faible d'énergie pour assurer le passage d'une position de commutation à l'autre.The present invention proposes to produce a microwave coaxial reversing relay of simple mechanical design, avoiding the use of return springs and requiring only low energy consumption to ensure the passage from a switching position to the other.
Le relais selin l'invention se caractérise par le fait que la lameressort est fixée dans sa partie centrale à une saillie disposée à l'aplomb du contact coaxial central, ladite lame-ressort comportant de part et d'autre de sa partie centrale, des moyens pour la fixation desdits poussoirs, et que la palette comporte des moyens pour, lours de son basculement, exercer un appui sur ladite lame-ressort au voisinage des extrémités de celle-ci.The selin relay of the invention is characterized by the fact that the spring spring is fixed in its central part to a projection arranged directly above the central coaxial contact, said leaf-spring comprising on either side of its central part, means for fixing said pushers, and that the pallet comprises means for, during its tilting, exert a support on said leaf spring in the vicinity of the ends thereof.
Dans un mode particulier de réalisation la palette comporte à ses extrémités des prolongements en forme de tiges comportant chacune un moyen d'appui sur la lame-ressort, par example une perle de verre.In a particular embodiment, the pallet has at its ends rod-shaped extensions each comprising a means of support on the leaf spring, for example a glass bead.
Dans un mode particulier de réalisation, chacun des poussoirs comporte pour sa fixation sur la lame-ressort une gorge de retenue, ladite lame-ressort comportant pour la mise en place et la fixation de chacun des poussoirs un orifice de diamètre correspondant à celui du poussoir prolongé par une fente longitudinale. Avantageusement, la gorge dans chaque poussoir présente en sens longitudinal, dans la position de retenue sur la lame-ressort, une partie centrale de section rétrécie s'élargissant en direction des extrémités, permettant ainsi un certain débattement élastique de la lame-ressort par rapport aux poussoirs, lors de l'appui de la palette sur la lame-ressort.In a particular embodiment, each of the pushers comprises for its fixing on the leaf spring a retaining groove, said leaf spring comprising for the positioning and fixing of each of the pushers a hole of diameter corresponding to that of the pushbutton extended by a longitudinal slit. Advantageously, the groove in each pusher has in the longitudinal direction, in the retaining position on the leaf spring, a central part of narrowed section widening towards the ends, thus allowing a certain elastic movement of the leaf spring relative to to the pushers, when the pallet is pressed on the leaf spring.
Dans un mode de réalisation préféré de l'invention, la lame-ressort comporte un orifice central pour son engagement sur une saillie faisant partie d'une platine isolante, de préférence en matière plastique moulée d'un seul tenant, disposée sur le plan de masse et comportant des orifices pour le passage des poussoirs, et des moyens de support de l'axe de pivotement de la palette. La platine comporte également les orifices nécessaires pour le passage des vis d'assemblage du relais.In a preferred embodiment of the invention, the leaf spring has a central orifice for its engagement on a projection forming part of an insulating plate, preferably made of molded plastic material, arranged on the plane of mass and comprising orifices for the passage of the pushers, and means for supporting the pivot axis of the pallet. The plate also has the holes necessary for the passage of the relay assembly screws.
De façon avantageuse la platine comporte en outre sur sa face opposée à celle suportant ladite saillie, des pions isolants, de préférence moulés d'un seul tenant, traversant le plan de masse et servant au guidage vertical des lames rigides de contact fixées avantageusement chacune à l'extrémité de chaque poussoir opposée à celle par laquelle celui-ci est fixé sur la lame-ressort de poussée.Advantageously, the plate further comprises on its face opposite to that supporting said projection, insulating pins, preferably molded in one piece, crossing the ground plane and serving for the vertical guidance of the rigid contact blades each advantageously fixed to the end of each plunger opposite to that by which it is fixed to the thrust leaf spring.
Grâce à l'invention, le plan de masse, distinct de la platine isolante, peut être facilement réalisé par découpage d'une plaque métallique mince.Thanks to the invention, the ground plane, distinct from the insulating plate, can be easily produced by cutting out a thin metal plate.

La course supplémentaire de la palette avant d'arriver en butée par sa branche 12 contre la masse polaire 9 a pour effet de cambrer la lame- ressort 19 créant les pressions de contact nécessaires des lames rigides 28 contre les contacts coaxiaux et respectivement le plan de masse.The additional stroke of the pallet before coming into abutment by its
Le réglage des pressions de contact et la compensation des tolérances mécaniques de montage peuvent être obtenus par cambrage des tiges 17 supportant les perles de verre 18.The adjustment of the contact pressures and the compensation of the mechanical mounting tolerances can be obtained by bending the
Les dimensions mécaniques sont déterminées pour que de l'entrée du relais vers la voie non commutée, dans l'exemple représenté le contact coaxial 3, l'on réalise un guide d'ondes fonctionnant, pour la fréquence d'utilisation du relais inverseur, en dessous de sa fréquence de coupure.The mechanical dimensions are determined so that from the input of the relay to the non-switched channel, in the example shown the coaxial contact 3, a working waveguide is produced, for the frequency of use of the reversing relay, below its cutoff frequency.
