Description

La présente invention concerne un système destiné à établir, en hyperfréquence, la continuité électrique entre deux éléments conducteurs.The present invention relates to a system for establishing, in microwave, the electrical continuity between two conductive elements.

On connaît déjà, à cette fin, des systèmes comportant un joint annulaire électriquement conducteur, qui est disposé entre des faces de jonction coopérantes, prévues respectivement sur lesdits éléments conducteurs et qui est pressé entre lesdites faces de jonction grâce à l'ac­tion de moyens de serrage desdits éléments conducteurs l'un contre l'autre.To this end, systems are already known which have an electrically conductive annular seal, which is disposed between cooperating junction faces, provided respectively on said conductive elements and which is pressed between said junction faces by the action of means of clamping said conductive elements against each other.

Dans ces systèmes connus, lesdits joints sont réali­sés soit en un silicone électriquement conducteur, soit en un tricot de fils conducteurs. Dans les deux cas, la liaison électrique entre les deux éléments conducteurs résulte de la mise en forme desdits joints sous l'action de la pression exercée sur eux par lesdits éléments conducteurs soumis à l'action desdits moyens de serrage. Or, une telle mise en forme des joints s'apparente au fluage. Ainsi, il en résulte :
- que la continuité électrique entre les deux éléments ne peut être obtenue immédiatement après serrage de ceux-ci;
- que la qualité de la continuité électrique (coefficient d'atténuation et coefficient de réflexion) dépend du serrage desdits éléments ; et
- que la répétabilité d'un état particulier de continuité électrique ne peut être assurée.In these known systems, said seals are made either of an electrically conductive silicone, or of a knitted fabric of conductive wires. In both cases, the electrical connection between the two conductive elements results from the shaping of said seals under the action of the pressure exerted on them by said conductive elements subjected to the action of said clamping means. However, such a shaping of the joints is similar to creep. Thus, it follows:
- that electrical continuity between the two elements cannot be obtained immediately after tightening them;
- that the quality of electrical continuity (attenuation coefficient and reflection coefficient) depends on the tightening of said elements; and
- that the repeatability of a particular state of electrical continuity cannot be ensured.

Ainsi, ces systèmes connus ne peuvent être utilisés si l'on recherche à la fois une continuité électrique quasi-immédiate et une répétabilité de connection. Ces systèmes connus sont donc limités aux liaisons permanen­tes.Thus, these known systems cannot be used if we are looking for both near-immediate electrical continuity and repeatability of connection. These known systems are therefore limited to permanent connections.

La présente invention a pour objet de remédier à ces inconvénients. Elle concerne un système permettant, en hyperfréquence, la continuité électrique quasi-instanta­née, constante dans le temps et répétitive, entre deux éléments.The object of the present invention is to remedy these drawbacks. It relates to a system allowing, in microwave, almost instantaneous electrical continuity, constant in time and repetitive, between two elements.

A cette fin, selon l'invention, le système destiné à établir, en hyperfréquence, la continuité électrique en­tre deux éléments conducteurs, ledit système comportant un joint annulaire électriquement conducteur, qui est disposé entre des faces de jonction coopérantes prévues respectivement sur lesdits éléments conducteurs et qui est pressé entre lesdites faces de jonction grâce à l'action de moyens de serrage desdits éléments conduc­teurs l'un contre l'autre, est remarquable en ce que :
- ledit joint annulaire est en un métal élastique et pré­sente la forme d'une rondelle ;
- la face de jonction de l'un desdits éléments conduc­teurs comporte une saillie annulaire dirigée vers l'autre élément conducteur et entourant un évidement ;
- la face de jonction de l'autre desdits éléments conduc­teurs comporte au moins une portion d'appui disposée en regard de ladite saillie annulaire, de façon que la partie périphérique de ladite rondelle puisse être pressée entre ladite saillie annulaire et ladite por­tion d'appui, grâce à l'action desdits moyens de serra­ge ; et
- des moyens de blocage sont prévus pour maintenir la partie centrale de ladite rondelle à l'intérieur dudit évidement, au moins lorsque lesdits éléments conduc­teurs sont rapprochés l'un de l'autre, de façon que, lorsque lesdits éléments conducteurs sont pressés l'un contre l'autre, ladite rondelle se déforme élastique­ment de facon non irréversible pour prendre la forme d'un pavillon évasé en direction dudit autre élément.To this end, according to the invention, the system intended to establish, in microwave, the electrical continuity between two conductive elements, said system comprising an electrically conductive annular seal, which is disposed between cooperating junction faces provided respectively on said conductive elements and which is pressed between said junction faces by the action of means for clamping said conductive elements one against the other, is remarkable in that:
- Said annular seal is made of an elastic metal and has the shape of a washer;
- The junction face of one of said conductive elements has an annular projection directed towards the other conductive element and surrounding a recess;
- The junction face of the other of said conductive elements comprises at least one bearing portion disposed opposite said annular projection, so that the peripheral part of said washer can be pressed between said annular projection and said bearing portion, thanks to the action of said clamping means; and
- Locking means are provided to maintain the central part of said washer inside said recess, at least when said conductive elements are brought towards one another, so that, when said conductive elements are pressed one against the other, said washer deforms elastically in a non-irreversible manner to take the form of a flared pavilion towards said other element.

Afin de faciliter, à la fois, la déformation élasti­que de ladite rondelle lors du serrage desdits éléments conducteurs et le retour élastique de ladite rondelle à sa forme de repos lors du desserrage de ceux-ci, il est avantageux que ladite rondelle présente une forme tronco­nique. Ainsi, la partie convexe de ladite rondelle étant disposée dans ledit évidement, les déformations subies par la rondelle au serrage sont moindres, ce qui permet de plus d'utiliser pour fabriquer la rondelle des métaux conducteurs relativement peu élastiques. Par exemple, la­dite rondelle peut être réalisée en cuivre au béryllium, éventuellement traité thermiquement.In order to facilitate, at the same time, the elastic deformation of said washer when tightening said conductive elements and the elastic return of said washer to its resting form when they are loosened, it is advantageous for said washer to have a frustoconical shape . Thus, the convex part of said washer being disposed in said recess, the deformations undergone by the tightening washer are less, which moreover makes it possible to use relatively inelastic conductive metals for manufacturing the washer. For example, said washer can be made of beryllium copper, optionally heat treated.

La rondelle pourrait être portée par ledit autre des­dits éléments conducteurs et n'être amenée au contact de l'élément pourvu de la saillie circulaire qu'au moment du serrage desdits éléments. Dans ce cas, lesdits moyens de blocage pourraient être portés par cet autre élément. Toutefois, dans un mode de réalisation avantageux, les­dits moyens de blocage établissent une liaison mécanique entre la partie centrale de la rondelle et la partie centrale dudit évidement. De plus, il est avantageux que lesdits moyens de blockage assurent le centrage de ladite rondelle par rapport à ladite saillie annulaire. Par exemple, ces moyens de blocage comportent un axe solidai­re de l'élément pourvu de la saillie, ladite rondelle étant traversée par ledit axe. De préférence, ledit axe porte une tête disposée dans la convexité de la rondelle et servant de butée vers l'extérieur de celle-ci.The washer could be carried by said other of said conductive elements and be brought into contact with the element provided with the circular projection only when said elements are tightened. In this case, said means of blockage could be worn by this other item. However, in an advantageous embodiment, said blocking means establish a mechanical connection between the central part of the washer and the central part of said recess. In addition, it is advantageous that said blocking means ensure the centering of said washer relative to said annular projection. For example, these locking means comprise an axis integral with the element provided with the projection, said washer being crossed by said axis. Preferably, said axis carries a head disposed in the convexity of the washer and serving as a stop towards the outside of the latter.

De préférence, afin de pouvoir régler, avant serrage desdits éléments l'un contre l'autre, la pression de ladite rondelle contre ledit élément comportant la sail­lie annulaire, ledit axe est une vis engagée dans un taraudage pratiqué dans ledit élément.Preferably, in order to be able to adjust, before tightening said elements one against the other, the pressure of said washer against said element comprising the annular projection, said axis is a screw engaged in a tapping made in said element.

  • La figure 3 montre le système des figures 1 et 2 à la fin de l'assemblage, mais toutefois avant serrage complet des deux éléments conducteurs l'un contre l'autre.
The figures of the appended drawing will make it clear how the invention can be implemented. In these figures, identical references designate identical elements.
  • Figure 1 is an exploded view, partially in longitudinal section, of an embodiment of the system according to the present invention.
  • Figure 2 shows the system of Figure 1 during assembly.
  • Figure 3 shows the system of Figures 1 and 2 at the end of assembly, but however before complete tightening of the two conductive elements one against the other.

Le système montré par ces figures est destiné à éta­blir la continuité électrique, en hyperfréquence, entre deux éléments conducteurs 1 et 2, susceptibles d'être pressés l'un contre l'autre par l'intermédiaire d'au moins une vis 3, qui traverse l'élément 2 par un trou 3a et qui est susceptible de coopérer avec un trou taraudé 4 pratiqué dans l'élément 1.The system shown in these figures is intended to establish electrical continuity, in microwave, between two conductive elements 1 and 2, capable of being pressed against each other by means of at least one screw 3, which crosses the element 2 through a hole 3a and which is capable of cooperating with a tapped hole 4 made in the element 1.

L'élément 1 comporte une face de jonction 5, dirigée vers l'élément 2 et pourvue d'un évidement 6, qui est entouré par une saillie annulaire 7. La face 8 de la saillie annulaire 7, dirigée vers l'élément 2, est avan­tageusement plane et est limitée, du côté de l'évidement 6, par une arête circulaire 9. Dans le fond 10 de l'évi­dement 6 est pratiqué un trou taraudé 11, par exemple coaxial au trou taraudé 4.The element 1 comprises a junction face 5, directed towards the element 2 and provided with a recess 6, which is surrounded by an annular projection 7. The face 8 of the annular projection 7, directed towards the element 2, is advantageously planar and is limited, on the side of the recess 6, by a circular edge 9. In the bottom 10 of the recess 6 is made a tapped hole 11, for example coaxial with the tapped hole 4.

L'élément 2 comporte une face de jonction 12 qui com­porte au moins une portion d'appui annulaire 13 suscepti­ble d'être appliquée contre la face 8 de la saillie annu­laire 7 de l'élément 1.The element 2 comprises a junction face 12 which comprises at least one annular bearing portion 13 capable of being applied against the face 8 of the annular projection 7 of the element 1.

Une vis 14, pourvue d'une tête 15, est susceptible d'être vissée dans le trou taraudé 11 de l'élément 1.A screw 14, provided with a head 15, is capable of being screwed into the tapped hole 11 of the element 1.

Le système comporte de plus, une rondelle tronconique 16, percée d'un trou central 17, et réalisée en une matière métallique élastiquement déformable, telle que le cuivre au béryllium, ayant éventuellement subi un traite­ ment thermique pour accroître sa déformabilité élastique. Le diamètre de la rondelle 16 est supérieur à celui de l'arête circulaire 9.The system further comprises a frustoconical washer 16, pierced with a central hole 17, and made of an elastically deformable metallic material, such as beryllium copper, which may have been treated thermally to increase its elastic deformability. The diameter of the washer 16 is greater than that of the circular edge 9.

Comme l'illustre la figure 2, pour assembler le sys­tème conforme à la présente invention, on commence par introduire la vis 14, dans le trou central 17 de la ron­delle 16, de façon que la tête 15 de ladite vis se trouve dans la concavité de ladite rondelle. Ensuite, la vis 14 est vissée dans le trou taraudé 11 de l'élément 1, la convexité de la rondelle 16 étant alors dirigée vers l'évidement 6.As illustrated in FIG. 2, to assemble the system according to the present invention, one begins by introducing the screw 14, into the central hole 17 of the washer 16, so that the head 15 of said screw is in the concavity of said washer. Then, the screw 14 is screwed into the tapped hole 11 of the element 1, the convexity of the washer 16 then being directed towards the recess 6.

Le vissage de la vis 14 dans le trou taraudé est de préférence poursuivi jusqu'à ce que la surface convexe de la rondelle 16 vienne en appui contre l'arête circulaire interne 9 de la saillie annulaire 7 (voir la figure 2). Il est également préférable que, dans cette position, la tête 15 de la vis 14 soit en appui contre la surface concave de la rondelle 16 et que la périphérie du trou central 17 soit pressée contre le fond 10 de l'évidement. Dans cette position, la vis 14 peut ou non exercer une contrainte de pression sur la rondelle 16. De plus, cette position, comme cela est représenté sur les figures, peut correspondre au vissage maximal de la vis 14 dans le trou taraudé 11.The screwing of the screw 14 into the tapped hole is preferably continued until the convex surface of the washer 16 comes to bear against the internal circular edge 9 of the annular projection 7 (see FIG. 2). It is also preferable that, in this position, the head 15 of the screw 14 bears against the concave surface of the washer 16 and that the periphery of the central hole 17 is pressed against the bottom 10 of the recess. In this position, the screw 14 may or may not exert a pressure stress on the washer 16. In addition, this position, as shown in the figures, can correspond to the maximum screwing of the screw 14 in the tapped hole 11.

Bien que la position décrite ci-dessus soit préférée, elle n'est pas obligatoire et, comme on le verra par la suite, la rondelle 16 peut, à cet instant du montage, ne pas être rendue rigidement solidaire de l'élément 1 par l'intermédiaire de la vis 14. Au contraire, cette vis 14 peut n'assurer qu'un liaison lâche entre la rondelle 16 et l'élément 1, ladite rondelle pouvant alors coulisser de façon limitée sur la vis 14 entre deux butées consti­tuées respectivement par l'arête circulaire interne 9 de la saillie 7 et par la tête 15 de la vis 14.Although the position described above is preferred, it is not compulsory and, as will be seen below, the washer 16 may, at this time of assembly, not not be made rigidly secured to the element 1 by means of the screw 14. On the contrary, this screw 14 can only provide a loose connection between the washer 16 and the element 1, said washer then being able to slide from limited way on the screw 14 between two stops constituted respectively by the internal circular edge 9 of the projection 7 and by the head 15 of the screw 14.

Quel que soit le degré de rigidité de la liaison entre la vis 14 et l'élément 1, on voit que la vis 14, en coopération avec le bord du trou central 17 de la rondel­le 16, assure le guidage et le centrage de celle-ci, par rapport à la saillie annulaire 7.Whatever the degree of rigidity of the connection between the screw 14 and the element 1, it can be seen that the screw 14, in cooperation with the edge of the central hole 17 of the washer 16, guides and centers it. ci, with respect to the annular projection 7.

Après mise en place de la rondelle 16 sur l'élément 1, l'élément 2 est rapproché de celui-ci et la vis 3 est vissée dans le trou taraudé 4. Au cours de ce vissage, la portion d'appui annulaire 13 de la face de jonction 12 presse la partie périphérique de la rondelle 16 en direction de la face 8 de la saillie 7. Le vissage de la vis 3 est poursuivi jusqu'à ce que cette partie périphérique de la rondelle 16 soit fortement pressée entre la face 8 de la saillie 7 et ladite portion d'appui annulaire 13.After placing the washer 16 on the element 1, the element 2 is brought closer to it and the screw 3 is screwed into the tapped hole 4. During this screwing, the annular bearing portion 13 of the junction face 12 presses the peripheral part of the washer 16 in the direction of the face 8 of the projection 7. The screwing of the screw 3 is continued until this peripheral part of the washer 16 is strongly pressed between the face 8 of the projection 7 and said annular bearing portion 13.

Puisque la partie centrale de la rondelle 16 est (quel que soit le serrage de la vis 14 dans le trou taraudé 11) prisonnière de la vis 14, ladite rondelle prend la forme au moins approximative du pavillon d'un instrument de musique à vent (voir la figure 3).Since the central part of the washer 16 is (whatever the tightening of the screw 14 in the tapped hole 11) captive of the screw 14, said washer takes the shape of at least the approximate horn of a wind musical instrument ( see figure 3).

Lorsque la vis 3 est dévissée, et que les éléments 1 et 2 s'écartent, la pression subie par la rondelle 16 diminue jusqu'à s'annuler et celle-ci reprend sa forme initiale (figures 1 et 2).When the screw 3 is unscrewed, and the elements 1 and 2 move apart, the pressure undergone by the washer 16 decreases until it is canceled and the latter returns to its initial shape (FIGS. 1 and 2).
