However, the new ranges of electronic equipment require compact solutions incorporating a plurality of different types of connectors, for example coaxial or signals, including radiofrequency or optoelectronic.
En outre, le connecteur selon le brevet
L'invention a pour but de proposer un système d'interconnexion de deux cartes électroniques adapté à un grand nombre de types différents de connecteurs, c'est-à-dire aussi bien des connecteurs coaxiaux que de signaux, et qui permette d'interconnecter les deux cartes de façon simple, efficace et robuste.The object of the invention is to propose a system for interconnecting two electronic cards adapted to a large number of different types of connectors, that is to say both coaxial connectors and signals, and that makes it possible to interconnect both cards in a simple, efficient and robust way.
Selon l'un de ses aspects, l'invention a ainsi pour objet un système d'interconnexion entre deux cartes électroniques, notamment de deux cartes électroniques disposées parallèlement, caractérisé par le fait qu'il comporte :
- un premier et un deuxième sous-ensemble comportant des logements recevant chacun au moins un connecteur, le premier, respectivement deuxième, sous-ensemble étant configuré pour être fixé sur une première, respectivement deuxième, carte électronique, et
- un troisième sous-ensemble de couplage, comportant des logements recevant des raccords de connecteurs, lesdits raccords étant configurés pour raccorder les connecteurs du premier sous-ensemble avec les connecteurs du deuxième sous-ensemble, le troisième sous-ensemble étant configuré pour être disposé entre les premier et deuxième sous-ensembles.
- a first and a second subassembly comprising housings each receiving at least one connector, the first, respectively second, subassembly being configured to be fixed on a first, respectively second, electronic card, and
- a third coupling subassembly, comprising housings receiving connector connectors, said connectors being configured to connect the connectors of the first subassembly with the connectors of the second subassembly, the third subassembly being configured to be disposed between the first and second subsets.
Un tel système d'interconnexion, grâce au sous-ensemble de couplage, peut permettre de prendre en compte lors de l'assemblage des mésalignements de différentes natures entre les différentes cartes électroniques, par exemple des mésalignements axiaux et/ou angulaires.Such an interconnection system, thanks to the coupling sub-assembly, can make it possible to take into account, during assembly, misalignments of different types between the different electronic boards, for example axial and / or angular misalignments.
Lorsque les deux cartes à interconnecter sont parallèles, on désignera par « hauteur » une distance mesurée selon une direction perpendiculaire aux plans dans lesquels s'étendent lesdites cartes.When the two cards to be interconnected are parallel, "height" will be used to denote a distance measured in a direction perpendicular to the planes in which said cards extend.
Par la suite, on dira que le système est assemblé lorsque les cartes électroniques sont interconnectées.Subsequently, it will be said that the system is assembled when the electronic cards are interconnected.
Les premier et deuxième sous-ensembles peuvent être des boîtiers.The first and second subassemblies can be housings.
En variante, seuls les premier et deuxième sous-ensembles sont des boîtiers, le troisième sous-ensemble n'étant pas un boîtier.As a variant, only the first and second sub-assemblies are housings, the third subassembly not being a housing.
Les connecteurs peuvent être maintenus de façon amovible dans les logements du premier et du deuxième sous-ensemble, par exemple par encliquetage.The connectors can be held removably in the housing of the first and second subassemblies, for example by snapping.
Les connecteurs disposés dans les sous-ensembles peuvent comprendre des connecteurs de deux types différents, notamment des connecteurs coaxiaux, par exemple des embases coaxiales, et des connecteurs de signaux. Il s'agit par exemple de deux types de connecteurs au moins parmi les connecteurs coaxiaux, les connecteurs radiofréquences, les connecteurs optoélectroniques Par la suite, on utilisera également le terme « connecteur » pour désigner des contacts de signaux, notamment des contacts radiofréquences, optoélectroniques...The connectors arranged in the sub-assemblies may comprise connectors of two different types, in particular coaxial connectors, for example coaxial bases, and signal connectors. For example, there are two types of connectors, at least among the coaxial connectors, the radio frequency connectors, the optoelectronic connectors. Thereafter, the term will also be used. "Connector" to designate signal contacts, in particular radiofrequency, optoelectronic contacts, etc.
Les connecteurs peuvent encore être des paires de connecteurs blindés configurés pour véhiculer des signaux électriques analogiques ou numériques, à basses ou à hautes fréquence. Les connecteurs peuvent encore être des connecteurs configurés pour assurer l'alimentation électrique des cartes électroniques.The connectors may further be pairs of shielded connectors configured to carry analog or digital electrical signals at low or high frequency. The connectors can still be connectors configured to provide power to the electronic cards.
Les extrémités des connecteurs du premier sous-ensemble disposées en regard du troisième sous-ensemble lors de l'assemblage peuvent être du même type que les extrémités des connecteurs du deuxième sous-ensemble disposées en regard du troisième sous-ensemble lors de l'assemblage, lesdites extrémités n'étant par exemple que des extrémités de type mâle. En variante, lesdites extrémités ne sont que des extrémités de type femelle. En variante encore, les extrémités des connecteurs du premier sous-ensemble disposées en regard du troisième sous-ensemble lors de l'assemblage du système sont de typé différent des extrémités des connecteurs du deuxième sous-ensemble disposées en regard du troisième sous-ensemble lors de l'assemblage, les unes n'étant par exemple que de type mâle et les autres que de type femelle ou inversement.The ends of the connectors of the first subassembly disposed opposite the third subassembly during assembly may be of the same type as the ends of the connectors of the second subassembly disposed opposite the third subassembly during assembly. , said ends being for example only ends of the male type. In a variant, said ends are only female-type ends. As a further variant, the ends of the connectors of the first subassembly disposed facing the third subassembly during assembly of the system are of different types of ends of the connectors of the second subassembly disposed opposite the third subassembly when of the assembly, some being for example only of the male type and the others that of female type or vice versa.
Les deux extrémités de chaque raccord de connecteurs peuvent être de même type, par exemple mâle. En variante, chaque raccord possède deux extrémités de type femelle. En variante encore, chaque raccord possède une extrémité de type mâle et une autre extrémité de type femelle. Dans d'autres exemples, le troisième sous-ensemble peut recevoir des raccords dont les deux extrémités sont de type mâle, des raccords dont les deux extrémités sont de type femelle et/ou des raccords dont l'extrémité face au premier sous-ensemble est de type mâle et dont l'extrémité face au deuxième sous-ensemble est de type femelle.The two ends of each connector connector can be of the same type, for example male. In a variant, each connector has two female-type ends. In another variant, each connection has a male-type end and another female-type end. In other examples, the third subassembly may receive connectors having both ends of the male type, connectors having both ends of the female type and / or connectors whose end facing the first subassembly is male type and whose end facing the second subassembly is female type.
L'invention permet ainsi de réaliser un système d'interconnexion entre deux cartes électroniques intégrant des signaux différents.The invention thus makes it possible to provide an interconnection system between two electronic cards incorporating different signals.
L'un au moins du premier, du deuxième et du troisième sous-ensemble comporte avantageusement au moins un bras de guidage configuré pour venir au contact de l'autre du premier, du deuxième sous-ensemble et du troisième sous-ensemble lors de l'assemblage du système d'interconnexion. De telles structures de guidage peuvent faciliter le centrage d'un sous-ensemble par rapport aux autres et, ainsi, l'assemblage du système.At least one of the first, second and third subassemblies advantageously comprises at least one guide arm configured to come into contact with the other of the first, the second subassembly and the third subassembly during the first assembly. assembly of the interconnection system. Such guiding structures can facilitate the centering of a subassembly relative to others and thus the assembly of the system.
Le troisième sous-ensemble peut comporter des moyens de guidage et/ou d'accrochage à l'un au moins des premier et deuxième sous-ensembles. La présence de tels moyens d'accrochage, qui peuvent faire saillie depuis le troisième sous-ensemble en direction du premier ou du deuxième sous-ensemble peut protéger des extrémités de type mâle des raccords de connecteurs reçus dans le troisième sous-ensemble.The third subassembly may comprise guide means and / or attachment to at least one of the first and second subsets. The presence of such hooking means, which can protrude from the third subassembly towards the first or second subassembly can protect male ends of connector connectors received in the third subassembly.
En variante, le premier ou le deuxième sous-ensemble comporte ces moyens d'accrochage au troisième sous-ensemble, le troisième sous-ensemble ne comportant que des moyens de guidage vis-à-vis du premier ou deuxième sous-ensemble.As a variant, the first or the second subassembly comprises these attachment means to the third subassembly, the third subassembly comprising only guide means vis-à-vis the first or second subassembly.
Le premier, respectivement deuxième, respectivement troisième, sous-ensemble comporte avantageusement une pluralité d'unités configurées pour être assemblées de façon amovible pour former le premier, respectivement deuxième, respectivement troisième sous-ensemble. L'invention permet ainsi d'obtenir un système d'interconnexion d'une grande modularité, un grand nombre d'unités pouvant être assemblées pour former les sous-ensembles. Il est ainsi possible de faire varier le nombre de connecteurs interconnectant les deux cartes électroniques en fonction de l'utilisation.The first, respectively second, respectively third, subassembly advantageously comprises a plurality of units configured to be removably assembled to form the first, respectively second, respectively third subset. The invention thus makes it possible to obtain an interconnection system of great modularity, a large number of units being able to be assembled to form the subassemblies. It is thus possible to vary the number of connectors interconnecting the two electronic cards depending on the use.
La fixation amovible des unités entre elles pour former le premier, le deuxième ou le troisième sous-ensemble est par exemple mise en oeuvre par coopérations de reliefs de forme complémentaire portés par lesdites unités, notamment des nervures et des rainures, et/ou grâce à des moyens d'encliquetage actionnables tels que des pattes d'encliquetage.The removable attachment of the units together to form the first, the second or the third subassembly is for example implemented by cooperations of reliefs of complementary shape carried by said units, in particular ribs and grooves, and / or thanks to actuable latching means such as latching lugs.
Au moins une unité, notamment chaque unité, peut comprendre entre deux et deux cents logements voire entre deux et quatre cents logements.At least one unit, in particular each unit, may comprise between two and two hundred dwellings or between two and four hundred dwellings.
Le premier, respectivement deuxième, respectivement troisième, sous-ensemble peut comporter au moins une unité ne comportant que des logements recevant des connecteurs d'un seul type, par exemple des connecteurs coaxiaux, et au moins une autre unité peut comporter des logements ne recevant que des connecteurs d'un autre type, par exemple des connecteurs de signaux.The first, respectively second, respectively third, subset may comprise at least one unit comprising only housings receiving connectors of a single type, for example coaxial connectors, and at least one other unit may comprise housings receiving only connectors of another type, for example signal connectors.
En variante, une unité comporte des logements recevant des connecteurs d'un premier type et une autre unité comporte des logements recevant des connecteurs d'un premier type et des logements recevant des connecteurs d'un deuxième type, différent du premier type, les connecteurs du premier type étant par exemple des connecteurs coaxiaux et les connecteurs du deuxième type étant par exemple des connecteurs de signaux.As a variant, a unit comprises housings receiving connectors of a first type and another unit comprises housings receiving connectors of a first type and housings receiving connectors of a second type, different from the first type, connectors of the first type being, for example, coaxial connectors and the connectors of the second type being, for example, signal connectors.
En variante encore, un sous-ensemble est formé d'unités de tailles différentes, présentant notamment un nombre différent de logements, ces unités ne recevant que des connecteurs du même type.In another variant, a subset is formed of units of different sizes, including a different number of slots, these units receiving only connectors of the same type.
En variante encore, un sous-ensemble peut être formé d'au moins une unité comportant des logements recevant des connecteurs d'un premier type seulement, d'au moins une unité comportant des logements recevant des connecteurs d'un deuxième type seulement et d'au moins une unité comportant des logements recevant des connecteurs des premier et deuxième types.As a further variant, a subset may be formed of at least one unit comprising housings receiving connectors of a first type only, of at least one unit comprising housings receiving connectors of a second type only and of at least one unit having housings receiving connectors of the first and second types.
Le troisième sous-ensemble peut comporter au moins une unité comprenant deux coques de formes complémentaires, par exemple deux demi-coques, qui définissent entre-elles, lorsqu'assemblées, les logements recevant les raccords de connecteurs, chacun desdits logements étant ouvert à deux extrémités opposées définies par des ouvertures dans la paroi de chaque coque.The third subassembly may comprise at least one unit comprising two hulls of complementary shapes, for example two half-shells, which define, when assembled, the housings receiving the connector connectors, each of said housings being open to two opposite ends defined by openings in the wall of each shell.
L'emploi de deux demi-coques ou de deux coques de même forme peut permettre de n'utiliser, lorsque ces coques sont réalisées par moulage, qu'un seul moule, permettant ainsi de réduire les coûts de fabrication.The use of two half-shells or two shells of the same shape can allow to use, when these shells are made by molding, a single mold, thus reducing manufacturing costs.
En variante, le troisième sous-ensemble comporte deux coques destinées à être chacune rapportée sur un des premier et deuxième sous-ensembles. Chaque coque comporte par exemple des moyens d'accrochage sur un des premier et deuxième sous-ensembles. Lorsque chaque coque du troisième sous-ensemble est rapportée sur un des premier et deuxième sous-ensembles et le système assemblé, lesdites coques peuvent ne pas être en contact l'une de l'autre. Chaque coque peut ne s'étendre que sur une fraction de la hauteur du troisième sous-ensemble.As a variant, the third subassembly comprises two shells intended to be each attached to one of the first and second subassemblies. Each shell comprises, for example, hooking means on one of the first and second subassemblies. When each shell of the third subassembly is attached to one of the first and second subassemblies and the assembled system, said shells may not be in contact with each other. Each shell may extend only a fraction of the height of the third subset.
Ainsi, les coques peuvent favoriser le basculement des raccords de connecteurs dans le troisième sous-ensemble pour compenser les mésalignements entre les cartes électroniques.Thus, the shells can promote the tilting of connector connectors in the third subassembly to compensate for misalignments between the electronic boards.
La ou les coques du troisième sous-ensemble rapportées sur le premier sous-ensemble et la ou les coques du troisième sous-ensemble rapportées sur le deuxième sous-ensemble peuvent ne pas être reliées les unes aux autres autrement que par l'intermédiaire des raccords de connecteurs lorsque le système est assemblé. Avec un tel troisième sous-ensemble, le système peut être utilisé pour interconnecter des cartes électroniques espacées de distances différentes. En effet, seule la hauteur des raccords de connecteurs du troisième sous-ensemble dépend alors de la distance séparant les deux cartes électroniques et seule cette hauteur des raccords de connecteurs doit alors être modifiée. Les mêmes coques peuvent ainsi être utilisées pour réaliser le troisième sous-ensemble d'un système d'interconnexion, quelle que soit la distance séparant les cartes à interconnecter.The shell or hulls of the third subassembly reported on the first subassembly and the shell or hulls of the third subassembly reported on the second subassembly may not be connected to each other other than via the couplings. connectors when the system is assembled. With such a third subset, the system can be used to interconnect electronic cards spaced at different distances. Indeed, only the height of the connectors connectors of the third subset then depends on the distance separating the two electronic boards and only this height of the connector connectors must then be modified. The same shells can thus be used to make the third subset of an interconnection system, regardless of the distance between the cards to be interconnected.
En variante, le troisième sous-ensemble peut comporter des moyens de liaison de la ou des coques rapportées sur le premier sous-ensemble à la ou aux coques rapportées sur le deuxième sous-ensemble. Ces moyens de liaison peuvent ou non être configurés pour être élastiquement déformables, de manière à pouvoir s'adapter à des distances entre cartes électroniques différentes. Ces moyens de liaison peuvent par exemple être réalisés en caoutchouc. Lesdits moyens de liaison, peuvent permettre de maintenir la position neutre entre les coques, c'est-à-dire une position dans laquelle les raccords de connecteurs sont reçus droits dans chaque coque, n'étant pas en position basculée.Alternatively, the third subassembly may comprise means for connecting the shell or shells reported on the first subset to the shell or shells reported on the second subset. These connecting means may or may not be configured to be elastically deformable, so as to be able to adapt to distances between different electronic cards. These connecting means may for example be made of rubber. Said connecting means, can maintain the neutral position between the shells, that is to say a position in which the connector connectors are received straight in each shell, not being in the tilted position.
Dans les deux variantes ci-dessus, le troisième sous-ensemble est solidaire, c'est-à-dire d'un seul tenant, une fois chaque coque en place sur le premier, respectivement deuxième sous-ensemble et le système assemblé.In the two variants above, the third subassembly is integral, that is to say in one piece, once each shell in place on the first, respectively second subassembly and the assembled system.
Les moyens d'accrochage d'une coque du troisième sous-ensemble sur le premier ou le deuxième sous-ensemble peuvent être configurés de manière à ce que les surfaces en regard d'une coque et du premier ou deuxième sous-ensemble sur lequel la coque est accrochée ne soient pas en contact, un jeu selon une direction sensiblement perpendiculaire aux plans dans lesquels s'étendent les cartes électroniques étant ménagé entre ces surfaces en regard. Ce jeu peut être compris entre 0 et 10 mm, étant par exemple inférieur à 3 mm. La présence d'un tel jeu peut permettre de compenser les tolérances de construction de tout ou partie des composants du système d'interconnexion selon une dimension perpendiculaire aux plans dans lesquels s'étendent les cartes électroniques.The attachment means of a shell of the third subassembly on the first or the second subassembly can be configured so that the facing surfaces of a shell and the first or second subassembly on which the shell hung are not in contact, a game in a direction substantially perpendicular to the plans in which the electronic cards extend being formed between these facing surfaces. This clearance can be between 0 and 10 mm, being for example less than 3 mm. The presence of such a game can make it possible to compensate for the construction tolerances of all or part of the components of the interconnection system in a dimension perpendicular to the planes in which the electronic cards extend.
En outre, chaque coque et le premier et/ou le deuxième sous-ensemble peuvent être configurées de manière à ce que lorsqu'une coque est accrochée sur le premier ou le deuxième sous-ensemble, une portion de la coque soit disposée autour d'une portion du premier ou du deuxième sous-ensemble avec un jeu selon une direction appartenant à un plan parallèle aux plans dans lesquels s'étendent les cartes électroniques. Ce jeu est par exemple compris entre 0 et 2 mm et peut permettre le basculement des raccords de connecteurs portés par la coque par rapport au premier ou au deuxième sous-ensemble, ce jeu permettant de compenser un mésalignement dans les plans dans lesquels s'étendent les cartes électroniques.In addition, each shell and the first and / or second subassembly can be configured so that when a shell is hung on the first or second subassembly, a portion of the shell is disposed around a portion of the first or second subassembly with a game in a direction belonging to a plane parallel to the planes in which the electronic cards extend. This clearance is for example between 0 and 2 mm and can allow the tilting of the connector connectors carried by the shell relative to the first or second subassembly, this game to compensate for a misalignment in the plans in which the electronic cards extend.
Au moins un raccord de connecteurs et une unité du troisième sous-ensemble peuvent comporter des moyens configurés pour maintenir ledit raccord, notamment de façon indémontable, dans un logement. Les raccords de connecteurs peuvent ainsi être rendus captifs dans le troisième sous-ensemble, ce dernier formant alors une structure solidaire.At least one connector connector and a unit of the third subassembly may comprise means configured to maintain said connector, particularly indemountably, in a housing. Connector connectors can thus be made captive in the third subassembly, the latter then forming a solidarity structure.
Lesdits moyens de maintien du raccord de connecteurs dans le logement comprennent par exemple au moins un relief, notamment une gorge annulaire, ménagé dans la surface extérieure du raccord et des pattes ménagées dans la paroi d'une coque en regard d'au moins une ouverture formant une extrémité du logement. Chaque raccord comporte par exemple à proximité de ses deux extrémités un tel relief, notamment une telle gorge, et chaque ouverture formant une extrémité de chaque logement est bordée par de telles pattes.Said means for holding the connector connector in the housing comprise for example at least one relief, in particular an annular groove, formed in the outer surface of the connector and tabs formed in the wall of a shell facing at least one opening forming one end of the housing. Each connection comprises for example near its two ends such a relief, including such a groove, and each opening forming an end of each housing is bordered by such tabs.
Les pattes peuvent être régulièrement réparties autour de l'ouverture. Les pattes sont par exemple deux à deux séparées par des fentes, lesdites fentes formant un motif en forme d'étoile lorsque le troisième sous-ensemble est vu du dessus. De telles pattes sont avantageusement configurées pour se déformer lors de l'introduction des raccords dans le troisième sous-ensemble, de façon à permettre un montage des raccords dans le troisième sous-ensemble qui soit aisé et indémontable.The legs can be evenly distributed around the opening. The tabs are for example two by two separated by slots, said slots forming a star-shaped pattern when the third subassembly is seen from above. Such tabs are advantageously configured to deform during the introduction of the fittings in the third subassembly, so as to allow assembly of the fittings in the third subassembly which is easy and unmountable.
En variante, chaque ouverture formant une extrémité de chaque logement peut ne pas être pourvue de pattes mais d'une lèvre, par exemple réalisée par amincissement de matière d'une coque, faisant saillie dans le logement et assurant le maintien du raccord de connecteurs reçu dans ledit logement.Alternatively, each opening forming one end of each housing may not be provided with tabs but with a lip, for example made by thinning material of a shell, projecting into the housing and ensuring the maintenance of the connector connector received in said housing.
En variante ou en combinaison des exemples de moyens de maintien ci-dessus, chaque logement ménagé dans le troisième sous-ensemble peut comporter à proximité d'au moins une de ses ouvertures une portion dont la surface intérieure est conique et chaque raccord de connecteurs peut comporter une portion dont la surface extérieure est sphérique et la coopération entre ces surfaces sphériques et coniques peut permettre d'obtenir une réception contrôlée des raccords de connecteurs dans les logements ménagés dans le troisième sous-ensemble, le troisième sous-ensemble comportant par ailleurs les moyens de liaison entre coques mentionnés ci-dessus.As a variant or in combination of the examples of holding means above, each housing formed in the third subassembly may comprise, in the vicinity of at least one of its openings, a portion whose interior surface is conical and each connector connection may have a portion whose outer surface is spherical and the cooperation between these spherical and conical surfaces can achieve a controlled reception connectors connectors in the housings in the third subassembly, the third subassembly further comprising the means of connection between hulls mentioned above.
Chaque logement du premier, respectivement deuxième, sous-ensemble peut comporter une extrémité destinée à venir en regard du troisième sous-ensemble lorsque le système d'interconnexion est assemblé, au moins un desdits logements comportant une portion d'extrémité s'étendant depuis ladite extrémité du logement vers l'intérieur dudit premier ou deuxième sous-ensemble et présentant une section transversale diminuant au fur et à mesure que l'on s'éloigne de ladite extrémité. Cette portion d'extrémité présente par exemple une forme en entonnoir, ce qui permet de guider dans les logements du premier et/ou du deuxième sous-ensemble les raccords de connecteurs du troisième sous-ensemble.Each housing of the first, respectively second, subset may comprise an end intended to come opposite the third subassembly when the interconnection system is assembled, at least one of said housing having an end portion extending from said end of the housing inwardly of said first or second subassembly and having a decreasing cross section as one moves away from said end. This end portion has for example a funnel shape, which guides in the housing of the first and / or second subassembly connector connectors of the third subassembly.
Les connecteurs et/ou raccords de connecteurs peuvent être de forme globalement tubulaire, étant par exemple des connecteurs droits, c'est-à-dire notamment non coudés.The connectors and / or connector connectors may be of generally tubular shape, for example being straight connectors, that is to say in particular not bent.
Les différentes unités et/ou coques mentionnées ci-dessus peuvent être réalisées en matiére(s) plastique(s) ou toute autre matière électriquement isolante.The various units and / or hulls mentioned above can be made of plastics or any other electrically insulating material.
L'invention a encore pour objet, selon un autre de ses aspects, un procédé d'interconnexion de deux cartes électroniques à l'aide du système d'interconnexion défini ci-dessus, caractérisé par le fait qu'il comporte les étapes suivantes :
- fixer le premier sous-ensemble et le deuxième sous-ensemble sur les première et deuxième cartes électroniques respectivement,
- assembler le troisième sous-ensemble et l'un du premier et du deuxième sous-ensemble et,
- assembler l'ensemble obtenu à l'issue de l'étape précédente à l'autre du premier et du deuxième sous-ensemble.
- attaching the first subset and the second subset to the first and second electronic cards respectively,
- assemble the third subset and one of the first and the second subset and,
- assembling the assembly obtained at the end of the preceding step to the other of the first and the second subassembly.
lorsque les connecteurs comprennent des connecteurs coaxiaux et des connecteurs de signaux, plusieurs pré-centrages peuvent être effectués lors de la mise en oeuvre du procédé ci-dessus. Un premier pré-centrage des différents sous-ensembles les uns par rapport aux autres est par exemple permis par le ou les bras de guidage.when the connectors comprise coaxial connectors and signal connectors, several pre-centerings can be made during the implementation of the method above. A first pre-centering of the different subassemblies relative to each other is for example allowed by the or the guide arms.
Un deuxième pré-centrage peut être permis par la coopération des raccords de connecteurs coaxiaux disposés dans le troisième sous-ensemble et des portions d'extrémité des logements des premier et/ou deuxième sous-ensembles lorsque ces raccords coaxiaux viennent à leur contact.A second pre-centering can be enabled by the cooperation of the coaxial connector connectors arranged in the third subassembly and end portions of the housing of the first and / or second subassemblies when these coaxial connectors come into contact with them.
Un troisième pré-centrage peut être permis par la coopération des raccords de connecteurs de signaux disposés dans le troisième sous-ensemble et des portions d'extrémité des logements des premier et/ou deuxième sous-ensembles lorsque ces raccords de connecteurs de signaux coaxiaux viennent à leur contact.A third pre-centering may be enabled by the cooperation of the signal connector connectors disposed in the third subassembly and portions end of the housing of the first and / or second subassemblies when these connectors coaxial signal connectors come into contact with them.

Dans l'exemple considéré, les coques 60 de la troisième structure 6 ne sont pas reliées entre elles. Il existe ainsi une zone vide V entre les deux coques 60, cette zone vide V recevant une portion médiane de chaque raccord de connecteurs 35 ou 36. La hauteur cumulée des coques 60 est ainsi inférieure à la hauteur du troisième sous-ensemble, étant par exemple inférieure à la moitié de la hauteur du troisième sous-ensemble.In the example considered, the
