Description

La présente invention concerne un dispositif de connexion. La présente invention concerne également un ensemble comprenant un tel dispositif de connexion et un dispositif électronique.The present invention relates to a connection device. The present invention also relates to an assembly comprising such a connection device and an electronic device.

Afin de transmettre un signal électrique entre deux dispositifs électroniques dits « hyperfréquence », de nombreux dispositifs de connexion coaxiaux sont utilisés. Ces dispositifs comportent en général deux embouts fixés, notamment par vissage, aux dispositifs à connecter, et transmettent le signal entre ces embouts via un câble coaxial. Ainsi, les embouts sont fixés solidement et avec précision aux contacts électriques des deux dispositifs à connecter.In order to transmit an electrical signal between two so-called “microwave” electronic devices, numerous coaxial connection devices are used. These devices generally comprise two end pieces fixed, in particular by screwing, to the devices to be connected, and transmit the signal between these end pieces via a coaxial cable. Thus, the end pieces are securely and precisely fixed to the electrical contacts of the two devices to be connected.

Cependant, afin de pouvoir visser les embouts aux dispositifs à connecter, il est nécessaire de prévoir autour de ces dispositifs un espace suffisant pour pouvoir passer la main ou un outil.However, in order to be able to screw the end pieces to the devices to be connected, it is necessary to provide around these devices sufficient space to be able to pass the hand or a tool.

En outre, le câble reliant les deux embouts est en général peu flexible. De ce fait, lorsque deux dispositifs à connecter sont situés l'un à côté de l'autre, il reste nécessaire de prévoir un espace pour permettre au câble de se déployer sans présenter de pliures ou de courbures excessives.In addition, the cable connecting the two end pieces is generally not very flexible. Therefore, when two devices to be connected are located next to each other, it remains necessary to provide a space to allow the cable to deploy without exhibiting excessive bends or bends.

Dans d'autres cas, la connexion entre deux dispositifs est effectuée par soudure ou brasure directement sur une carte de circuit imprimée. Il est alors difficile de séparer les deux dispositifs si l'un ou l'autre doit être remplacé. US9590359B1 décrit un connecteur électrique RF coaxial qui peut s'adapter aux variations de distance entre des composants couplés électriquement adjacents en étant compressible en longueur. Le document se concentre sur le maintien d'une impédance caractéristique constante lorsque la longueur varie.In other cases, the connection between two devices is made by soldering or soldering directly to a printed circuit board. It is then difficult to separate the two devices if one or the other has to be replaced. US9590359B1 describes a coaxial RF electrical connector that can accommodate variations in distance between adjacent electrically coupled components by being compressible in length. The paper focuses on maintaining a constant characteristic impedance as the length varies.

Il existe donc un besoin pour un dispositif de connexion électrique pour transmettre un signal, notamment un signal hyperfréquence, entre deux dispositifs, qui soit démontable et qui permette un arrangement plus compact des dispositifs à connecter.There is therefore a need for an electrical connection device for transmitting a signal, in particular a microwave signal, between two devices, which can be dismantled and which allows a more compact arrangement of the devices to be connected.

For example, each second electrical contact 100 is provided so that one of the ends 55, 60 of the second electrode 35 bears against the second electrical contact 100. when the connection device 10 is in the connection position.

Le deuxième contact électrique 100 est, par exemple, une piste de connexion électrique de forme analogue à la forme de la deuxième électrode 35 dans un plan perpendiculaire à l'axe D et portée par une surface du boîtier 75.The second electrical contact 100 is, for example, an electrical connection track of a shape similar to the shape of the second electrode 35 in a plane perpendicular to the axis D and carried by a surface of the housing 75.

Le deuxième contact électrique 100 est, par exemple, une piste de forme annulaire, ici de forme annulaire circulaire.The second electrical contact 100 is, for example, an annular-shaped track, here of circular annular shape.

Chaque deuxième contact électrique 100 est, par exemple, configuré pour relier à la masse la deuxième électrode 35.Each second electrical contact 100 is, for example, configured to ground the second electrode 35.

Le fonctionnement du dispositif de connexion 10 va maintenant être décrit.The operation of the connection device 10 will now be described.

Lors d'une première étape, le dispositif de connexion 10 est attaché au premier dispositif électronique 15 dans sa position de connexion.In a first step, the connection device 10 is attached to the first electronic device 15 in its connection position.

A l'issue de la première étape, la première électrode 30 est électriquement connectée au premier contact électrique 95 du premier dispositif électronique 15. En particulier, la première extrémité 55 de la première électrode 30 est en appui contre la troisième extrémité 105 du premier contact électrique 95 du premier dispositif électronique 15.At the end of the first step, the first electrode 30 is electrically connected to the first electrical contact 95 of the first electronic device 15. In particular, the first end 55 of the first electrode 30 bears against the third end 105 of the first contact. electrical 95 of the first electronic device 15.

A l'issue de la première étape, la deuxième extrémité 60 de chaque électrode 30, 35 est libre. Chaque deuxième extrémité 60 est donc dans sa première position.At the end of the first step, the second end 60 of each electrode 30, 35 is free. Each second end 60 is therefore in its first position.

Lors d'une deuxième étape, le dispositif de connexion 10 est également attaché au deuxième dispositif électronique 20.In a second step, the connection device 10 is also attached to the second electronic device 20.

L'attachement du dispositif de connexion 10 au deuxième dispositif électronique 20 entraîne la mise en appui de chaque deuxième extrémité 60 contre le premier contact électrique 95 ou le deuxième contact électrique 100 correspondant du deuxième dispositif électronique 20. Cette mise en appui entraîne le déplacement de chaque deuxième portion 70 mobile depuis sa première position jusqu'à sa deuxième position.Attaching the connection device 10 to the second electronic device 20 causes each second end 60 to bear against the first electrical contact 95 or the corresponding second electrical contact 100 of the second electronic device 20. This bearing causes the displacement of each second portion 70 movable from its first position to its second position.

Il est à noter que l'ordre des première et deuxième étapes est susceptible d'être inversé.It should be noted that the order of the first and second stages is likely to be reversed.

Lors d'une troisième étape, le signal électrique est transmis entre les deux dispositifs électroniques 15, 20 par le dispositif de connexion 10. En particulier, la masse est transmise par la deuxième électrode 35, et le signal électrique est transmis par la première électrode 30.During a third step, the electrical signal is transmitted between the two electronic devices 15, 20 by the connection device 10. In particular, the ground is transmitted by the second electrode 35, and the electrical signal is transmitted by the first electrode. 30.

Grâce à l'utilisation de portions 65, 70 mobiles l'une par rapport à l'autre, l'attachement du dispositif de connexion 10 aux différents dispositifs électroniques 15, 20 est rendue aisé même si l'alignement entre les deux dispositifs électroniques 15, 20 n'est pas parfait. En particulier, la tolérance de cet attachement vis-à-vis d'une rotation relative entre les deux dispositifs électroniques 15, 20 est augmentée. En conséquence, la conception du dispositif de connexion 10 est simplifiée, et l'attachement du dispositif de connexion 10 à chaque dispositif électronique 15, 20 à l'aide d'un organe d'attachement 40 de plus petite dimension que les organes d'attachement habituels est possible. En outre, il n'est pas nécessaire de prévoir que le dispositif de connexion 10 soit en deux parties reliées par un câble.Thanks to the use of portions 65, 70 movable relative to each other, the attachment of the connection device 10 to the various electronic devices 15, 20 is made easy even if the alignment between the two electronic devices 15 , 20 is not perfect. In particular, the tolerance of this attachment with respect to relative rotation between the two electronic devices 15, 20 is increased. Accordingly, the design of the connection device 10 is simplified, and the attachment of the connection device 10 to each electronic device 15, 20 by means of an attachment member 40 of smaller dimension than the connection members. usual attachment is possible. In furthermore, it is not necessary to provide that the connection device 10 is in two parts connected by a cable.

Tout ceci participe à réduire les dimensions du dispositif de connexion 10, et à permettre un arrangement moins encombrant de l'ensemble formé par le dispositif de connexion 10 et les deux dispositifs électroniques 15, 20, le dispositif de connexion 10 restant détachable des deux dispositifs électroniques 15, 20.All this helps to reduce the dimensions of the connection device 10, and to allow a less bulky arrangement of the assembly formed by the connection device 10 and the two electronic devices 15, 20, the connection device 10 remaining detachable from the two devices. electronic 15, 20.

En outre, l'utilisation de portions 65, 70 mobiles, notamment avec un organe de rappel, permet de réguler la force exercée par le dispositif de connexion 10 sur les contacts électriques 95, 100 du connecteur 80 auquel le dispositif de connexion 10 est connecté. Cela évite notamment que le premier contact électrique 95 soit endommagé par une force trop grande, ou que le contact électrique entre les électrodes 30, 35 et les contacts électriques 95, 100 correspondants soit insuffisant.In addition, the use of movable portions 65, 70, in particular with a return member, makes it possible to regulate the force exerted by the connection device 10 on the electrical contacts 95, 100 of the connector 80 to which the connection device 10 is connected. . This prevents in particular that the first electrical contact 95 is damaged by too great a force, or that the electrical contact between the electrodes 30, 35 and the corresponding electrical contacts 95, 100 is insufficient.

Une extrémité 55, 60 concave permet d'accueillir la troisième extrémité 105 du premier contact électrique 95 correspondant. Ainsi, le placement respectif du dispositif de connexion 10 et du dispositif électronique 15, 20 correspondant est rendu plus aisé, car le contact électrique entre ces deux éléments est moins sensible à une imprécision de placement.A concave end 55, 60 makes it possible to accommodate the third end 105 of the corresponding first electrical contact 95. Thus, the respective placement of the connection device 10 and of the corresponding electronic device 15, 20 is made easier, since the electrical contact between these two elements is less sensitive to imprecision of placement.

Le choix d'une extrémité 55, 60 présentant une section triangulaire permet une connexion à un premier ou deuxième contact électrique 95, 100 de petite dimension.The choice of an end 55, 60 having a triangular section allows connection to a first or second electrical contact 95, 100 of small size.

Un organe de maintien 25 sous forme d'une plaque électriquement isolante est aisé à réaliser.A retaining member 25 in the form of an electrically insulating plate is easy to produce.

L'élément d'appui 110 permet de garantir un bon contact électrique entre une extrémité 55, 60 convexe de la première électrode 30 et un premier contact électrique 95 dont la troisième extrémité 105 est également convexe, notamment si ces deux extrémités sont fines. En effet, la plaque 115 permet d'augmenter la surface contre laquelle chacune de ces deux extrémités 55, 60 ou 105 doit être mise en appui.The support element 110 makes it possible to guarantee a good electrical contact between a convex end 55, 60 of the first electrode 30 and a first electrical contact 95, the third end 105 of which is also convex, in particular if these two ends are thin. In fact, the plate 115 makes it possible to increase the surface against which each of these two ends 55, 60 or 105 must be brought to bear.

Il en résulte également une plus grande flexibilité dans l'utilisation du dispositif de connexion 10, puisque les extrémités convexes des électrodes 30, 35 ne sont pas limitées à une utilisation avec des contacts électriques 95, 100 plats ou convexes.This also results in greater flexibility in the use of the connection device 10, since the convex ends of the electrodes 30, 35 are not limited to use with electrical contacts 95, 100 flat or convex.

Un deuxième exemple d'ensemble, qui ne fait pas partie de l'invention, formé d'un dispositif de connexion 10, d'un premier dispositif électronique 15 et d'un deuxième dispositif électronique 20 est représenté sur la figure 2. Les éléments identiques au premier exemple d'ensemble ne sont pas décrits à nouveau. Seules les différences sont mises en évidence.A second example of an assembly, which does not form part of the invention, formed of a connection device 10, of a first electronic device 15 and of a second electronic device 20 is shown in FIG. figure 2 . Items identical to the first example set are not described again. Only the differences are highlighted.

Sur la figure 2, le dispositif de connexion est représenté dans sa position de connexion. En particulier, les deux deuxièmes portions 70 sont chacune dans leur deuxième position.On the figure 2 , the connection device is shown in its connection position. In particular, the two second portions 70 are each in their second position.

La troisième extrémité 105 du premier contact électrique 95 d'au moins un dispositif électronique 15, 20 est concave. L'extrémité 55, 60 de la première électrode 30 qui est prévue pour venir en appui contre cette troisième extrémité 105 est, elle, convexe. En particulier, cette extrémité 55, 60 présente une section triangulaire dans un plan parallèle à l'axe D. Cette extrémité 55, 60 forme, notamment, un cône à base circulaire.The third end 105 of the first electrical contact 95 of at least one electronic device 15, 20 is concave. The end 55, 60 of the first electrode 30 which is designed to bear against this third end 105 is itself convex. In particular, this end 55, 60 has a triangular section in a plane parallel to the axis D. This end 55, 60 forms, in particular, a cone with a circular base.

Lorsque le dispositif de connexion 10 est dans la position de connexion, l'extrémité 55, 60 convexe de la première électrode 30 est accueillie dans la cavité formée par la troisième extrémité 105.When the connection device 10 is in the connection position, the convex end 55, 60 of the first electrode 30 is received in the cavity formed by the third end 105.

Sur la figure 2, la troisième extrémité 105 du premier contact électrique 95 du premier dispositif électronique est concave et la première extrémité 55 de la première électrode 30 est accueillie dans la troisième extrémité concave. Il est à noter que des modes de réalisation dans lesquels c'est la deuxième extrémité 60 qui est accueillie dans cette troisième extrémité 105 sont également envisageables.On the figure 2 , the third end 105 of the first electrical contact 95 of the first electronic device is concave and the first end 55 of the first electrode 30 is received in the third concave end. It should be noted that embodiments in which it is the second end 60 which is received in this third end 105 can also be envisaged.

Le premier contact électrique 95 d'au moins un connecteur 80 ne comporte pas d'ergot mais une piste électriquement conductrice 125. La piste électriquement conductrice 125 est, par exemple, portée par une carte de circuit imprimée, ou par une surface du boîtier 75.The first electrical contact 95 of at least one connector 80 does not include a lug but an electrically conductive track 125. The electrically conductive track 125 is, for example, carried by a printed circuit board, or by a surface of the housing 75. .

La distance d1, d2, d3 ou d4 correspondant à l'extrémité 55, 60 destinée à être mise en contact avec ce connecteur 80 est, par exemple, identique pour toutes les électrodes 30, 35. Selon l'exemple représenté sur la figure 2, la deuxième distance d2 est identique à la quatrième distance d4, parce que ce sont les deuxièmes extrémités 60 de ces deux électrodes 30, 35 qui sont en contact avec le connecteur 80 considéré.The distance d1, d2, d3 or d4 corresponding to the end 55, 60 intended to be brought into contact with this connector 80 is, for example, identical for all the electrodes 30, 35. According to the example shown in FIG. figure 2 , the second distance d2 is identical to the fourth distance d4, because it is the second ends 60 of these two electrodes 30, 35 which are in contact with the connector 80 considered.

Lorsque le premier contact électrique 95 présente une extrémité troisième extrémité 105 concave, le positionnement du dispositif de connexion 10 est, là encore, rendu plus aisé car la connexion électrique entre le premier contact électrique 95 et la première électrode 30 est peu sensible à un éventuel décalage spatial entre ces deux pièces.When the first electrical contact 95 has a third end 105 concave, the positioning of the connection device 10 is, again, made easier because the electrical connection between the first electrical contact 95 and the first electrode 30 is not very sensitive to a possible spatial shift between these two parts.

Il est à noter que toutes les combinaisons de géométries des premières et deuxièmes extrémités 55, 60 sont envisageables. Par exemple, les deuxièmes extrémités 60 représentées sur la figure 2 sont susceptibles d'être combinées avec les premières extrémités 55 représentées sur la figure 1, et vice-versa.It should be noted that all the combinations of geometries of the first and second ends 55, 60 can be envisaged. For example, the second ends 60 shown on figure 2 are likely to be combined with the first ends 55 shown on the figure 1 , and vice versa.

Il est à noter également que des modes de réalisation dans lesquels les deuxièmes extrémités 60 font chacune saillie à partir d'une face 45, 50 différente de l'organe de maintien 25 sont également envisageables. Dans ces modes de réalisation, les deuxièmes portions 70, mobiles par rapport à l'organe de maintien 25, sont situées de part et d'autre de cet organe de maintien 25 selon l'axe D.It should also be noted that embodiments in which the second ends 60 each protrude from a different face 45, 50 of the retaining member 25 are also conceivable. In these embodiments, the second portions 70, movable relative to the retaining member 25, are located on either side of this retaining member 25 along the axis D.

Selon une autre variante envisageable, le dispositif de connexion 10 ne comporte pas d'organe d'attachement 40, mais chaque dispositif électronique 15, 20 comporte un organe d'attachement configuré pour maintenir le dispositif de connexion dans la position de connexion.According to another conceivable variant, the connection device 10 does not include an attachment member 40, but each electronic device 15, 20 comprises an attachment member configured to hold the connection device in the connection position.

La deuxième électrode 35 a été décrite ci-dessus dans le cas où cette deuxième électrode 35 est une unique électrode annulaire entourant la première électrode 30 dans un plan perpendiculaire à l'axe D.The second electrode 35 has been described above in the case where this second electrode 35 is a single annular electrode surrounding the first electrode 30 in a plane perpendicular to the axis D.

Il est à noter que des modes de réalisation dans lesquels le dispositif de connexion 10 comporte au moins une deuxième électrode 35 telle que les première et deuxième électrodes 30, 35 sont agencées de manière non-coaxiale sont envisageables.It should be noted that embodiments in which the connection device 10 comprises at least one second electrode 35 such that the first and second electrodes 30, 35 are arranged in a non-coaxial manner are possible.

Le nombre de deuxièmes électrodes 35 et, par exemple, compris entre 1 et 10.The number of second electrodes 35 and, for example, between 1 and 10.

Lorsque le dispositif de connexion 10 comporte plusieurs deuxièmes électrodes 35, chaque deuxième électrode 35 est, par exemple, électriquement isolée des autres deuxièmes électrodes 35.When the connection device 10 comprises several second electrodes 35, each second electrode 35 is, for example, electrically isolated from the other second electrodes 35.

Selon une variante envisageable, au moins deux deuxièmes électrodes 35 sont électriquement connectées l'une à l'autre. Dans un mode de réalisation particulier, toutes les deuxièmes électrodes 35 sont électriquement connectées entre elles.According to a possible variant, at least two second electrodes 35 are electrically connected to one another. In a particular embodiment, all of the second electrodes 35 are electrically connected to one another.

Chaque deuxième électrode 35 est, par exemple, sensiblement cylindrique. En particulier, chacune de la première portion 65 et de la deuxième portion 70 de la deuxième électrode 35 est délimitée dans une plan perpendiculaire à l'axe D par une surface extérieure respective cylindrique.Each second electrode 35 is, for example, substantially cylindrical. In particular, each of the first portion 65 and of the second portion 70 of the second electrode 35 is delimited in a plane perpendicular to the axis D by a respective cylindrical outer surface.

Chaque deuxième électrode 35 présente un diamètre compris entre 0,25 mm et plusieurs millimètres.Each second electrode 35 has a diameter of between 0.25 mm and several millimeters.

Lorsque les première et deuxième électrodes 30, 35 ne sont pas coaxiales, les première et deuxième électrodes 30, 35 sont décalées l'une par rapport à l'autre dans un plan perpendiculaire à l'axe D. Par exemple, chaque première et deuxième électrodes 30, 35 s'étend selon un axe respectif parallèle à l'axe D, les axes de chaque première et deuxième électrodes 30, 35 étant distinct l'un de l'autre et décalés d'un par rapport à l'autre dans un plan perpendiculaire à l'axe D.When the first and second electrodes 30, 35 are not coaxial, the first and second electrodes 30, 35 are offset from each other in a plane perpendicular to the D axis. For example, each first and second electrodes 30, 35 extend along a respective axis parallel to the axis D, the axes of each first and second electrode 30, 35 being distinct from each other and offset from one another in a plane perpendicular to the D axis.

Selon un mode de réalisation, la première électrode 30 forme un agencement coaxial avec les deuxièmes électrodes 35. Par exemple, la première électrode 30 est au moins partiellement entourée par les deuxièmes électrodes 35 dans un plan perpendiculaire à l'axe D.According to one embodiment, the first electrode 30 forms a coaxial arrangement with the second electrodes 35. For example, the first electrode 30 is at least partially surrounded by the second electrodes 35 in a plane perpendicular to the axis D.

Par exemple, chaque deuxième électrode 35 s'étend selon un axe respectif parallèle à l'axe D, les axes de chaque deuxième électrode 35 étant agencée le long d'une ligne fermée imaginaire entourant l'axe D selon lequel la première électrode 30 s'étend.For example, each second electrode 35 extends along a respective axis parallel to the D axis, the axes of each second electrode 35 being arranged along an imaginary closed line surrounding the D axis along which the first electrode 30 s 'extends.

Dans un mode de réalisation particulier, chaque deuxième électrode 35 s'étend selon un axe respectif parallèle à l'axe D, les axes de chaque deuxième électrode 35 étant agencée le long d'un cercle centré sur l'axe D selon lequel la première électrode 30 s'étend.In a particular embodiment, each second electrode 35 extends along a respective axis parallel to the D axis, the axes of each second electrode 35 being arranged along a circle centered on the D axis along which the first electrode 30 extends.

Par exemple, le dispositif de connexion 10 comprend deux deuxièmes électrodes 35 et la première électrode 30 est interposée entre les deux deuxièmes électrodes 35. En particulier, les axes des deux deuxièmes électrodes 35 et l'axe D sont alignés dans un plan perpendiculaire à l'axe D. Encore plus particulièrement, les deux deuxièmes électrodes 35 sont équidistantes de la première électrode 30. En d'autres termes, les deux deuxièmes électrodes 35 sont diamétralement opposées par rapport à la première électrode.For example, the connection device 10 comprises two second electrodes 35 and the first electrode 30 is interposed between the two second electrodes 35. In particular, the axes of the two second electrodes 35 and the axis D are aligned in a plane perpendicular to the axis. axis D. Even more particularly, the two second electrodes 35 are equidistant from the first electrode 30. In other words, the two second electrodes 35 are diametrically opposed with respect to the first electrode.

Un tel dispositif de connexion 10 est simple à réaliser et particulièrement adapté à transmettre des signaux présentant une fréquence basse, dont les fréquences peuvent être de quelques centaines de Hz jusqu'à 1 MHz, voire plus élevées.Such a connection device 10 is simple to produce and particularly suitable for transmitting signals having a low frequency, the frequencies of which can be from a few hundred Hz up to 1 MHz, or even higher.

En variante, les axes des deuxièmes électrodes 35 sont disposés aux sommets d'un polygone à l'intérieur duquel se situe l'axe D, et en particulier centré sur l'axe D, et contenu dans un plan perpendiculaire à l'axe D.As a variant, the axes of the second electrodes 35 are arranged at the vertices of a polygon within which the axis D is located, and in particular centered on the axis D, and contained in a plane perpendicular to the axis D .

Selon un troisième exemple de dispositif de connexion 10 représenté sur la figure 3 dans une vue orientée selon l'axe D, le dispositif de connexion 10 comprend six deuxièmes électrodes 35 disposées aux sommets d'un hexagone compris dans un plan perpendiculaire à l'axe D, l'hexagone étant centré sur l'axe D.According to a third example of connection device 10 shown in figure 3 in a view oriented along the D axis, the connection device 10 comprises six second electrodes 35 arranged at the vertices of a hexagon included in a plane perpendicular to the D axis, the hexagon being centered on the D axis.

Un dispositif de connexion 10 dont les deuxièmes électrodes 35 sont ainsi positionnées aux sommets d'un polygone entourant la première électrode 30 est adapté à la transmission d'un signal même si ce signal présente une fréquence élevée. En particulier, le signal transmis par la première électrode 30 est ainsi isolé des interférences extérieures par les deuxièmes électrodes 35.A connection device 10, the second electrodes 35 of which are thus positioned at the vertices of a polygon surrounding the first electrode 30, is suitable for transmitting a signal even if this signal has a high frequency. In particular, the signal transmitted by the first electrode 30 is thus isolated from external interference by the second electrodes 35.

En outre, lorsque les différentes deuxièmes électrodes 35 sont électriquement isolées l'une de l'autre, plusieurs types de courants électriques ou de potentiels électriques sont susceptibles d'être transmis simultanément.Furthermore, when the different second electrodes 35 are electrically insulated from one another, several types of electric currents or electric potentials are capable of being transmitted simultaneously.

Par exemple, le signal hyperfréquence est transmis entre les deux dispositifs électroniques 15, 20 par la première électrode 30, la masse associée au signal est transmise par au moins une deuxième électrode 35, et une tension électrique d'alimentation d'un dispositif électronique 15, 20 est transmise par au moins une autre deuxième électrode 35. Les courants d'alimentation peuvent présente une intensité comprise entre quelques milliampères (mA) et plusieurs centaines de mA, en fonction des caractéristiques des composants à alimenter.For example, the microwave signal is transmitted between the two electronic devices 15, 20 by the first electrode 30, the mass associated with the signal is transmitted by at least one second electrode 35, and an electric voltage supply of an electronic device 15, 20 is transmitted by at least one other second electrode 35. The supply currents can have an intensity between a few milliamperes (mA) and several hundred mA, depending on the characteristics of the components to feed.

Les tensions électriques d'alimentation sont alors assimilables, du point de vue du signal hyperfréquence transmis, à des potentiels de masse, de sorte que l'isolation de la première électrode 30 contre les perturbations extérieures est efficace.From the point of view of the transmitted microwave signal, the electrical supply voltages can then be assimilated to ground potentials, so that the insulation of the first electrode 30 against external disturbances is effective.
