Abstract
Description
La présente invention concerne un connecteur électrique multivoie sans barrière électromagnétique entre les voies.The present invention relates to a multi-channel electrical connector without an electromagnetic barrier between the channels.
On connaît déjà des connecteurs électriques miniatures à plusieurs voies, chaque voie étant constituée par un élément de contact coaxial comportant un conducteur central et un conducteur externe, des moyens de raccordement à une plaque de circuit imprimé et une tige électriquement conductrice reliant le conducteur central de l'élément de contact coaxial auxdits moyens de raccordement.Miniature electrical connectors with several channels are already known, each channel being constituted by a coaxial contact element comprising a central conductor and an external conductor, means for connection to a printed circuit board and an electrically conductive rod connecting the central conductor of the contact element coaxial with said connection means.
Dans ces connecteurs connus, les tiges conductrices des différentes voies sont séparées deux à deux par une cloison conductrice qui a pour fonction de les isoler du point de vue électromagnétique pour éviter tout couplage entre les signaux véhiculés par deux tiges voisines.In these known connectors, the conductive rods of the different channels are separated in pairs by a conductive partition which has the function of isolating them from the electromagnetic point of view to avoid any coupling between the signals carried by two neighboring rods.
De tels connecteurs donnent généralement satisfaction mais ils présentent un certain nombre d'inconvénients.Such connectors are generally satisfactory but they have a number of drawbacks.
En particulier, leur fabrication pose un problème du fait que les cloisons qui séparent les différentes tiges conductrices définissent des canaux à l'intérieur du connecteur et qu'il est difficile, notamment lorsque le connecteur est coudé, d'introduire les tiges conductrices à l'intérieur de ces canaux.In particular, their manufacture poses a problem because the partitions which separate the different conductive rods define channels inside the connector and that it is difficult, especially when the connector is bent, to introduce the conductive rods to the inside these channels.
En outre, la réalisation de telles cloisons implique un prix de revient relativement élevé des connecteurs.In addition, the production of such partitions implies a relatively high cost price of the connectors.
De plus, ces cloisons constituent un obstacle à la miniaturisation du connecteur, lequel doit nécessairement comporter n-1 cloisons pour n tiges, d'où un certain encombrement.In addition, these partitions constitute an obstacle to the miniaturization of the connector, which must necessarily comprise n − 1 partitions for n rods, hence a certain bulk.
La présente invention vise à fournir un connecteur électrique multivoie qui ne présente notamment pas les inconvénients rappelés ci-dessus.The present invention aims to provide a multi-channel electrical connector which in particular does not have the drawbacks mentioned above.
La présente invention a pour objet un connecteur électrique multivoie, dans lequel chaque voie est constituée par un élément de contact coaxial comportant un conducteur central et un conducteur externe, des moyens de raccordement à une plaque de circuit imprimé et une tige électriquement conductrice reliant le conducteur central de l'élément de contact coaxial auxdits moyens de raccordement, caractérisé par le fait que les tiges conductrices sont logées dans un boîtier qui définit un espace intérieur continu, chaque tige conductrice étant disposée à proximité d'au moins un plan de masse et étant séparée de la ou des tiges conductrices voisines d'une distance supérieure à la distance qui la sépare de son plan de masse.The present invention relates to a multi-way electrical connector, in which each channel is constituted by a coaxial contact element comprising a central conductor and an external conductor, means for connection to a printed circuit board and an electrically conductive rod connecting the conductor central of the contact element coaxial with said connection means, characterized in that the conductive rods are housed in a housing which defines a continuous interior space, each conductive rod being arranged near at least one ground plane and being separated from the neighboring conductive rod (s) by a distance greater than the distance which separates it from its ground plane.
Ainsi, l'essentiel du rayonnement électromagnétique de chaque tige conductrice est capté par le plan de masse avant de parvenir à la ou aux tiges conductrices voisines.Thus, most of the electromagnetic radiation from each conductive rod is captured by the ground plane before reaching the neighboring conductive rod or rods.
On comprend que le connecteur selon l'invention présente l'avantage de pouvoir être miniaturisé dans de grandes proportions tout en étant d'un prix de revient relativement faible.It is understood that the connector according to the invention has the advantage of being able to be miniaturized in large proportions while being of a relatively low cost price.
Dans un mode de réalisation préféré de l'invention, les tiges conductrices sont logées dans un milieu diélectrique dont la constante diélectrique est déterminée pour que, compte tenu du diamètre de chaque tige et de la distance qui sépare cette tige de son ou de ses plans de masse, l'impédance de chaque voie ait une valeur désirée.In a preferred embodiment of the invention, the conductive rods are housed in a dielectric medium whose dielectric constant is determined so that, taking into account the diameter of each rod and the distance which separates this rod from its plane or planes mass, the impedance of each channel has a desired value.
Dans une variante de ce mode de réalisation, le connecteur comporte un second milieu diélectrique de constante diélectrique différente qui sépare le premier milieu diélectrique du ou des plans de masse.In a variant of this embodiment, the connector comprises a second dielectric medium of different dielectric constant which separates the first dielectric medium from the ground plane (s).
Par exemple, les tiges conductrices peuvent être placées dans un premier milieu diélectrique constitué par de l'air et prendre appui contre une couche de matière plastique appliquée sur le plan de masse, cette couche de matière plastique constituant un second milieu diélectrique.For example, the conductive rods can be placed in a first dielectric medium consisting of air and bear against a layer of plastic material applied to the ground plane, this layer of plastic material constituting a second dielectric medium.
Conformément à l'invention, le boîtier est réalisé de préférence en un matériau électriquement conducteur et joue le rôle de blindage vis-à-vis de l'extérieur.According to the invention, the housing is preferably made of an electrically conductive material and plays the role of shielding from the outside.
Dans un premier mode de réalisation de l'invention, il est prévu un seul plan de masse formé de préférence par une paroi du boîtier, et au voisinage duquel sont disposées les tiges conductrices.In a first embodiment of the invention, there is provided a single ground plane preferably formed by a wall of the housing, and in the vicinity of which the conductive rods are arranged.
Dans un second mode de réalisation de l'invention, il est prévu deux plans de masse parallèles constitués de préférence par deux parois du boîtier et entre lesquels sont disposées les tiges conductrices.In a second embodiment of the invention, two parallel ground planes are provided, preferably constituted by two walls of the housing and between which the conductive rods are arranged.
Dans le but de mieux faire comprendre l'invention, on va en décrire maintenant trois modes de réalisation donnés à titre d'exemples non limitatifs, en référence au dessin annexé dans lequel :
- la figure 1 est une vue en perspective d'un connecteur selon un premier mode de réalisation de l'invention,
- la figure 2 est une vue en coupe selon II-II de la figure 1,
- la figure 3 est une vue analogue à la figure 2 d'un connecteur selon un deuxième mode de réalisation de l'invention,
- la figure 4 est une vue en perspective d'un connecteur selon un troisième mode de réalisation de l'invention à l'état démonté, et
- la figure 5 est une vue en coupe selon V-V de la figure 4 du connecteur à l'état monté.
- FIG. 1 is a perspective view of a connector according to a first embodiment of the invention,
- FIG. 2 is a sectional view along II-II of FIG. 1,
- FIG. 3 is a view similar to FIG. 2 of a connector according to a second embodiment of the invention,
- FIG. 4 is a perspective view of a connector according to a third embodiment of the invention in the disassembled state, and
- Figure 5 is a sectional view along VV of Figure 4 of the connector in the assembled state.
Sur le dessin, on a représenté une plaque de circuit imprimé 1 sur laquelle est monté un connecteur 2 comportant un support métallique 3 en forme de L, dont la branche inférieure 4 est solidarisée à la plaque 1 et comporte des perçages 5 garnis de gaines isolantes 6 au travers desquelles s'engagent les extrémités de deux tiges conductrices coudées 7.In the drawing, there is shown a printed
Le support métallique 3 et les extrémités des tiges conductrices 7 sont fixées à la plaque de circuit imprimé 1 par des moyens conventionnels, notamment par soudure.The
Chaque tige conductrice 7 est reliée au conducteur central 8 d'un élément de contact coaxial 9 dont le conducteur externe 10 est soudé à la branche supérieure 11 du support métallique 3.Each
Un capot métallique 12 de forme parallélépipédique, comportant un fond et une face frontale ouverts, est monté de manière amovible sur le support métallique 3 par des moyens de fixation, non représentés, pour constituer un boîtier au sens de l'invention.A
Ce boîtier définit un espace intérieur continu dans lequel sont logées les deux tiges conductrices 7.This housing defines a continuous interior space in which the two
Comme on le voit sur la vue en coupe de la figure 2, les deux grandes faces 13,14 du capot 12 constituent des plans de masse parallèles séparés d'une distance L= 1,1 mm.As seen in the sectional view of Figure 2, the two
Les deux tiges conductrices 7 sont placées entre ces deux plans de masse. Le diamètre extérieur d = 0,6 mm de chaque tige conductrice 7 et la constante diélectrique K= 1 de l'air, qui constitue ici le seul milieu diélectrique dans lequel sont placées les tiges conductrices, permettent de déterminer l'impédance Z de chaque ligne en appliquant la formule approchée suivante :
Les tiges conductrices 7 sont écartées l'une de l'autre d'une distance D égale à 4 mm.The
Ainsi, pour des signaux alternatifs de fréquence comprise entre environ 100 MHz et 18 GHz, et de puissance comprise entre environ 0,1 et 10 W, on observe un couplage entre les voies de moins de 30 dB, ce qui peut être considéré comme négligeable.Thus, for alternating signals of frequency between approximately 100 MHz and 18 GHz, and of power between approximately 0.1 and 10 W, one observes a coupling between the channels of less than 30 dB, which can be considered as negligible .
Dans le mode de réalisation représenté à la figure 3, les tiges conductrices 7 sont situées à proximité d'une des parois 14 du capot métallique.In the embodiment shown in Figure 3, the
La distance qui sépare les tiges conductrices 7 de l'autre paroi 13 du capot métallique est suffisamment grande pour que l'influence sur les tiges conductrices 7 de cette autre paroi 13 puisse être considérée comme négligeable, voire nulle, du point de vue électromagnétique.The distance between the
Néanmoins, le capot 12 remplit une fonction de blindage vis-à-vis de l'extérieur, comme dans le mode de réalisation précédent.However, the
Dans ce mode de réalisation de la figure 3, on a prévu, en plus de la lame d'air de constante diélectrique K1 = 1 dans laquelle sont placées les tiges conductrices 7, un second matériau diélectrique 15 constitué par une couche de PTFE (polytétrafluoroéthylène), dont la constante diélectrique K2 est de 2.In this embodiment of Figure 3, there is provided, in addition to the air gap of dielectric constant K1 = 1 in which are placed the
Si la distance L' qui sépare l'axe de chaque tige conductrice du plan de masse est d'environ 0,5 mm, l'impédance Z de chaque ligne électrique est d'environ 50 Ω:If the distance L ' which separates the axis of each conductive rod from the ground plane is approximately 0.5 mm, the impedance Z of each electrical line is approximately 50 Ω:
Dans ce mode de réalisation, les tiges conductrices sont séparées d'une distance D'= 4 mm.In this embodiment, the conductive rods are separated by a distance D '= 4 mm.
Dans ce cas, pour des signaux dont la puissance est au maximum de 10 W, et dont la fréquence est comprise entre 100 MHz et 18 GHz, on observe un couplage entre les voies inférieur à 30 dB, ce qui peut être considéré comme négligeable.In this case, for signals whose power is at most 10 W, and whose frequency is between 100 MHz and 18 GHz, a coupling between the channels is observed below 30 dB, which can be considered negligible.
On peut noter par ailleurs que le second milieu diélectrique 15 procure un avantage concernant la fabrication du boîtier 12 en constituant une cale qui permet de positionner les tiges conductrices 7 à une distance voulue du plan de masse 14 en les appliquant contre cette couche 15.It may also be noted that the second
Dans le troisième mode de réalisation, représenté sur les figures 4 et 5, le connecteur 2' comporte un boîtier métallique 3' qui présente, dans un plan parallèle au circuit imprimé 1, une section en forme de U visible sur la figure 5.In the third embodiment, shown in FIGS. 4 and 5, the
Dans sa partie frontale 16, qui forme la base du U en figure 5, le boîtier 3' est plein et comporte deux alésages 17 dans lesquels s'engagent les conducteurs externes 10, lesquels sont soudés ou insérés à force dans les alésages 17.In its
Dans sa partie arrière 18, qui forme les deux branches du U en figure 5, le boîtier 3' comporte deux parois planes parallèles 13', 14'.In its
L'extrémité arrière 19 du boîtier 3' est ouverte.The
Les deux tiges conductrices 7 sont surmoulées dans un bloc de matériau diélectrique 15' réalisé par exemple en polyimide.The two
Les dimensions du bloc 15' correspondent sensiblement aux dimensions intérieures de l'espace compris entre les parois 13' et 14' du boîtier 3'.The dimensions of the block 15 'correspond substantially to the internal dimensions of the space between the walls 13' and 14 'of the housing 3'.
Le bloc 15' est destiné à être inséré dans le boîtier 3' entre ses deux parois parallèles 13' et 14', comme on le voit sur la figure 5.The block 15 'is intended to be inserted into the housing 3' between its two parallel walls 13 'and 14', as seen in FIG. 5.
Chaque tige conductrice 7 s'engage à l'intérieur du conducteur externe 10 correspondant et son extrémité 8' dirigée vers la partie frontale 18 du boîtier constitue le conducteur central d'un contact coaxial 9' ainsi réalisé.Each
Une fois le bloc 15' inséré dans le boîtier 3', la face arrière 19 du boîtier peut être obturée par une plaque électriquement conductrice non représentée, destinée à constituer un blindage électromagnétique vis-à-vis de l'extérieur du boîtier.Once the
Il est bien entendu que les modes de réalisation qui viennent d'être décrits ne présentent aucun caractère limitatif et qu'ils pourront recevoir toutes modifications désirables sans sortir pour cela du cadre de l'invention.It is understood that the embodiments which have just been described have no limiting character and that they can receive any desirable modifications without departing from the scope of the invention.
