Description

La présente invention concerne un connecteur coaxial hyperfréquence. Un tel connecteur est destiné notamment à relier deux cartes de circuit imprimé ou encore une carte de circuit imprimé à un autre composant tel qu'un module ou un filtre.The present invention relates to a coaxial microwave connector. Such a connector is intended in particular to connect two printed circuit boards or a printed circuit board to another component such as a module or a filter.

Par « connecteur hyperfréquence », on entend ici et dans le cadre de la présente invention, un connecteur apte à assurer la transmission de signaux dans la gamme des hyperfréquences, par exemple à des fréquences comprises entre 1 GHz et 20 GHz.By "microwave connector" is meant here and in the context of the present invention, a connector capable of ensuring the transmission of signals in the microwave range, for example at frequencies between 1 GHz and 20 GHz.

Par « contact », on entend ici et dans le cadre de la présente invention, un élément en matériau conducteur électrique pour laisser passer le courant électrique.By "contact" is meant here and in the context of the present invention, an element of electrically conductive material for passing the electric current.

A contrario, un « élément isolant » est un élément en matériau isolant électrique.Conversely, an "insulating element" is an element of electrical insulating material.

Pour établir une liaison coaxiale entre deux cartes de circuit imprimé parallèles et proches l'une de l'autre, on connaît les connecteurs coaxiaux, comportant un premier élément de connecteur cylindrique destiné à être fixé, par une extrémité, à une première carte de circuit imprimé, et un deuxième élément de connecteur cylindrique destiné à venir au contact, par une extrémité, d'une deuxième carte de circuit imprimé, chaque élément de connecteur comportant un contact central et un contact extérieur séparés par un isolant, les contacts centraux et extérieurs des premier et deuxième éléments de connecteurs comportant des portées cylindriques mutuellement en contact, des moyens élastiques étant interposés entre les premier et deuxième éléments de connecteur et sollicitant les contacts central et extérieur du deuxième élément de connecteur en direction de la deuxième carte de circuit imprimé.To establish a coaxial connection between two printed circuit boards parallel and close to one another, the coaxial connectors are known, comprising a first cylindrical connector element intended to be fixed at one end to a first circuit board printed, and a second cylindrical connector member for contacting, at one end, a second printed circuit board, each connector member having a central contact and an outer contact separated by an insulator, the central and outer contacts first and second connector members having mutually contacting cylindrical bearing surfaces, resilient means being interposed between the first and second connector members and biasing the central and outer contacts of the second connector member towards the second printed circuit board.

Le premier élément de connecteur peut être fixé mécaniquement, notamment par brasage, à la première carte de circuit imprimé et la deuxième carte est amenée en appui contre le second élément de connecteur qui est déplacé relativement au premier élément de connecteur, les contacts du second élément de connecteur étant pressés sous l'action des moyens élastiques contre les zones conductrices prévues sur la deuxième carte. Ainsi, ces moyens élastiques sont nécessaires pour obtenir un effort de contact mécanique suffisant, garant d'un bon contact électrique.The first connector element may be mechanically fastened, in particular by soldering, to the first printed circuit board and the second card is brought in abutment against the second connector element which is displaced relative to the first connector element, the contacts of the second element connector being pressed under the action of the elastic means against the conductive zones provided on the second card. Thus, these elastic means are necessary to obtain a sufficient mechanical contact force, ensuring a good electrical contact.

Des moyens auxiliaires assurent le maintien en position de la seconde carte de circuit imprimé à proximité de la première carte de circuit imprimé, empêchant ainsi le second élément de connexion de se déconnecter vis-à-vis du premier élément de connexion et de la seconde carte de circuit imprimé.Auxiliary means ensures that the second printed circuit board is held in position near the first printed circuit board, thereby preventing the second connection element to disconnect from the first connection element and the second circuit board.

Un connecteur de ce type dans lequel les moyens élastiques sont des joints toriques en élastomère est décrit dans le brevet US 6 699 054 . L'ajout de joints toriques rend complexe la conception de ce connecteur.A connector of this type in which the elastic means are elastomer O-rings is described in the patent US 6,699,054 . The addition of O-rings makes the design of this connector difficult.

La demande de brevet DE 102005033911 divulgue un connecteur dans lequel les moyens élastiques sont constitués par un ressort hélicoïdal central qui constitue également le contact central. Un inconvénient majeur est que l'un des contacts de masse sous la forme d'un cylindre plein n'est pas réellement compressible, ce qui ne garantit pas un bon contact électrique de masse et d'absorber des tolérances de carte-à carte relativement importantes. En outre, le ressort central induit une inductance trop importante, inadaptée pour la transmission de signaux en hyperfréquence.The patent application DE 102005033911 discloses a connector in which the elastic means are constituted by a central helical spring which is also the central contact. A major disadvantage is that one of the mass contacts in the form of a solid cylinder is not really compressible, which does not guarantee a good electrical ground contact and absorb card-to-card tolerances relatively important. In addition, the central spring induces excessive inductance, unsuitable for the transmission of microwave signals.

Le brevet US 7416418 divulgue un connecteur coaxial hyperfréquence, dit carte-à-carte, dans lequel un premier ressort est intercalé axialement entre les tiges conductrices des éléments de connexion. Un second ressort est intercalé axialement entre les corps conducteur des éléments de connexion. Le premier élément de connexion est fixé à la première carte de circuit imprimé. Lorsque la deuxième carte de circuit imprimé est amenée contre le second élément de connexion, les ressorts repoussent la tige et le corps du second élément de connexion contre la seconde carte de circuit imprimé, à l'opposé du premier élément de connexion, de manière à assurer un contact électrique satisfaisant entre le second élément de connexion et la seconde carte de circuit imprimé. La structure de ce connecteur reste relativement complexe, en particulier compte tenu de l'utilisation de ressorts.The patent US 7416418 discloses a microwave coaxial connector, said card-to-board, wherein a first spring is interposed axially between the conductive rods of the connecting elements. A second spring is interposed axially between the conductive bodies of the connection elements. The first connection element is attached to the first printed circuit board. When the second printed circuit board is brought against the second connection element, the springs push the rod and the body of the second connection element against the second printed circuit board, opposite the first connection element, so as to ensuring a satisfactory electrical contact between the second connection element and the second printed circuit board. The structure of this connector remains relatively complex, especially given the use of springs.

Pour s'affranchir de l'inconvénient lié à l'utilisation des deux ressorts du brevet US 7416418 , la demanderesse a proposé un nouveau connecteur coaxial hyperfréquence de structure plus simple.To overcome the inconvenience related to the use of the two springs of the patent US 7416418 , the Applicant has proposed a new microwave coaxial connector of simpler structure.

La demande de brevet US2003/0060069 décrit un connecteur coaxial dont l'élément central peut être selon un mode de réalisation un ensemble constitué d'un corps cylindrique, d'une bille, d'une paroi cylindrique et d'un ressort hélicoïdal. Le corps cylindrique est en appui sur la bille, qui est elle-même en appui sur le ressort. L'emploi d'un ressort dans l'élément central rend la structure du connecteur particulièrement complexe.The patent application US2003 / 0060069 describes a coaxial connector whose central element may be according to one embodiment an assembly consisting of a cylindrical body, a ball, a cylindrical wall and a helical spring. The cylindrical body is supported on the ball, which is itself supported on the spring. The use of a spring in the central element makes the connector structure particularly complex.

La demande de brevet JP 2001-230035 divulgue un connecteur possédant une pluralité de contacts de type « coil-spring » répartis dans un réseau de trous. Ce connecteur n'est pas un connecteur coaxial.The patent application JP 2001-230035 discloses a connector having a plurality of "coil-spring" type contacts distributed in a network of holes. This connector is not a coaxial connector.

Outre les inconvénients précités, les connecteurs coaxiaux connus présentent une hauteur qui reste relativement importante dans leur position de connexion, ce qui induit de fait une limite inférieure de distance à laquelle il est possible de rapprocher les deux cartes de circuit imprimé qui reste encore relativement importante.In addition to the aforementioned disadvantages, the known coaxial connectors have a height which remains relatively large in their connection position, which in fact induces a lower limit of distance at which it is possible to bring the two printed circuit boards which is still relatively important. .

Or, les inventeurs ont été confrontés à un besoin de connecteur coaxial hyperfréquence pour relier deux cartes imprimées, séparées d'une distance de carte à carte très faible, typiquement inférieure à 1,5 mm, avec des tolérances relativement importantes en valeur relative mais faibles en valeur absolue, typiquement égales à 0,2 mm.However, the inventors have faced a need for a microwave coaxial connector to connect two printed cards, separated by a card-to-card distance very low, typically less than 1.5 mm, with relatively large tolerances in relative value but low in absolute value, typically equal to 0.2 mm.

L'invention vise à répondre à tout ou partie de ce besoin.The invention aims to meet all or part of this need.

L'invention a ainsi pour objet, un connecteur coaxial hyperfréquence, selon l'objet de la revendication 1, destiné notamment à relier deux cartes de circuit imprimé entre elles, caractérisé en ce qu'il comporte:

  • un premier contact extérieur comportant un corps de forme générale tubulaire d'axe longitudinal X comportant une première extrémité, une deuxième extrémité opposée à la première extrémité, et à sa périphérie extérieure, entre les première et deuxième extrémités, une surface de contact de forme évasée vers la deuxième extrémité,
  • un contact central comportant un élément conducteur allongé replié en partie sur lui-même en définissant une boucle apte à être fermée, élastiquement déformable, avec une de ses extrémités libres en dehors de la boucle,
  • un deuxième contact extérieur comportant un anneau ouvert, élastiquement déformable,
  • un élément isolant comportant une fente débouchante et allongée selon l'axe X, l'élément isolant étant agencé entre l'élément conducteur allongé et le corps tubulaire,
en ce que l'élément conducteur allongé à l'intérieur de l'élément isolant est tel que sa boucle puisse être fermée et déformée élastiquement par compression sur elle-même entre une position non déformée dans laquelle son sommet fait saillie au-delà de la première extrémité et une position extrême déformée dans laquelle son sommet est aligné sur la première extrémité, l'extrémité libre de l'élément conducteur allongé en dehors de la boucle étant apte à coulisser en faisant saillie de la fente de sorte à être alignée sur la deuxième extrémité quelle que soit la position déformée de la boucle,
et en ce que l'anneau est maintenu à l'extérieur du corps tubulaire de sorte qu'il puisse être déformé élastiquement par appui contre la surface évasée entre une position non déformée dans laquelle il n'est pas en appui contre la surface évasée et son sommet fait saillie au-delà de la première extrémité et une position extrême déformée dans laquelle son sommet est aligné sur la première extrémité.The object of the invention is therefore a microwave coaxial connector, according to the object of claim 1, intended in particular for connecting two printed circuit boards to one another, characterized in that it comprises:
  • a first outer contact comprising a generally tubular body of longitudinal axis X having a first end, a second end opposite the first end, and at its outer periphery, between the first and second ends, a flared contact surface towards the second end,
  • a central contact comprising an elongated conductive element partially folded on itself by defining a loop able to be closed, elastically deformable, with one of its free ends outside the loop,
  • a second external contact comprising an open ring, elastically deformable,
  • an insulating element having an emergent slot and elongate along the X axis, the insulating element being arranged between the elongated conductive element and the tubular body,
in that the elongate conductive element within the insulating element is such that its loop can be closed and elastically deformed by compression on itself between an undeformed position in which its vertex protrudes beyond the first end and a distorted extreme position in which its vertex is aligned with the first end, the free end of the elongated conductive element outside the loop being slidable by projecting from the slot so as to be aligned with the second end regardless of the deformed position of the loop,
and in that the ring is held outside the tubular body so that it can be elastically deformed by pressing against the flared surface between an undeformed position in which it is not resting against the flared surface and its top protrudes beyond the first end and a distorted extreme position in which its vertex is aligned with the first end.

Selon une variante de réalisation avantageuse, l'élément conducteur allongé est une lame.According to an advantageous embodiment, the elongated conductive element is a blade.

Par « lame », on entend ici et dans le cadre de l'invention, le sens technologique usuel du terme, i.e. une bande de métal de faible épaisseur et de faible largeur.By "blade" is meant here and in the context of the invention, the usual technological sense of the term, i.e. a metal strip of small thickness and small width.

Selon une autre variante, l'élément conducteur allongé est un fil de faible diamètre, dont les caractéristiques mécaniques satisfont aux exigences de déformations mécaniques requises.According to another variant, the elongate conductive element is a wire of small diameter, the mechanical characteristics of which satisfy the requirements of required mechanical deformations.

De préférence, la lame a une épaisseur comprise entre 0,05 et 0,15 mm et une largeur comprise entre 0.4 et 1 mm. A titre d'exemple, une lame à base de cuivre-béryllium CuBe2 de 0,07 mm d'épaisseur pour une largeur de 0,6 mm convient parfaitement pour la réalisation de l'invention.Preferably, the blade has a thickness of between 0.05 and 0.15 mm and a width of between 0.4 and 1 mm. For example, a 0.07 mm thick copper-beryllium CuBe 2 -based blade with a width of 0.6 mm is perfectly suitable for carrying out the invention.

Par « surface de forme évasée vers la deuxième extrémité », on entend ici et dans le cadre de l'invention, une surface qui s'élargie continument en direction de la deuxième extrémité. Autrement dit, la surface de contact est une surface soit en forme de tronc de cône, soit convexe par rapport à l'axe du connecteur et augmente de diamètre en direction de la deuxième extrémité du corps tubulaire.By "flared shape surface towards the second end" is meant here and in the context of the invention, a surface that widens continuously towards the second end. In other words, the contact surface is a surface that is in the form of a truncated cone, that is convex relative to the axis of the connector and that increases in diameter towards the second end of the tubular body.

Par « anneau ouvert », on entend ici et dans le cadre de l'invention, le sens technologique usuel du terme, i.e. une bague fendue ou un jonc fendu en un point de sa circonférence sur toute sa largeur.By "open ring" is meant here and in the context of the invention, the usual technological meaning of the term, i.e. a split ring or a ring split at a point of its circumference over its entire width.

Par « sommet », on entend ici et dans le cadre de l'invention, l'extrémité de la l'élément conducteur allongé ou l'extrémité de l'anneau la plus éloignée du corps dans sa position non déformée.By "vertex" is meant here and in the context of the invention, the end of the elongated conductive element or the end of the ring furthest from the body in its undeformed position.

Grâce à l'invention, on peut réaliser une connexion carte-à carte sur une très faible distance, typiquement inférieure ou égale à 2 mm, avec des tolérances relativement importantes en valeur relative mais faibles en valeur absolue, typiquement égales à 0,2 mm et, ce tout en garantissant un bon contact électrique entre toutes les pistes des circuits imprimé à connecter.Thanks to the invention, a card-to-card connection can be made over a very short distance, typically less than or equal to 2 mm, with relatively large tolerances in relative value but low in absolute value, typically equal to 0.2 mm. and, while ensuring a good electrical contact between all the tracks of the printed circuits to connect.

En effet, en mettant en oeuvre un seul contact central qui peut être déformé, la hauteur minimale du connecteur selon l'invention est définie uniquement par la hauteur du corps tubulaire rigide du contact de masse que l'on peut aisément rendre très faible.Indeed, by implementing a single central contact that can be deformed, the minimum height of the connector according to the invention is defined only by the height of the rigid tubular body of the mass contact that can easily be very low.

Les déformations élastiques à la fois de l'anneau et de l'élément conducteur allongé permettent d'absorber complètement les tolérances de distance entre cartes et par leur retour élastique de garantir des contacts électrique de qualité.The elastic deformations of both the ring and the elongated conductive member allow to fully absorb the distance tolerances between cards and their elastic return to ensure quality electrical contacts.

En outre, les inventeurs ont pu constater que le fait de s'assurer de la fermeture de la boucle confère une inductance relativement faible, ce qui est avantageux lors de la transmission de signaux hyperfréquences.In addition, the inventors have found that ensuring the closure of the loop provides a relatively low inductance, which is advantageous when transmitting microwave signals.

Le montage « carte à carte » à l'aide d'un connecteur coaxial selon l'invention peut être réalisé sans maintien préalable du connecteur avec l'une et/ou l'autre des cartes de circuit imprimé ou avec un maintien préalable notamment par brasage du corps premier conducteur extérieur à une des cartes, de préférence à celle inférieure. On précise ici que bien entendu les moyens de maintien préalable du connecteur à l'une et/ou l'autre des cartes sont clairement distincts des moyens de maintien mécanique permettant le maintien de la distance entre cartes afin de conserver la connexion électrique.The "board-to-board" assembly using a coaxial connector according to the invention can be realized without prior maintenance of the connector with one and / or the other of the printed circuit boards or with a prior maintenance in particular by brazing the first outer conductor body to one of the cards, preferably to the lower one. It should be noted here that, of course, the means of pre-holding the connector to one and / or the other of the cards are clearly distinct from the mechanical holding means enabling the distance between cards to be maintained in order to maintain the electrical connection.

Selon un mode de réalisation avantageux, le connecteur comporte au moins une protubérance faisant saillie dans l'élément isolant à l'intérieur de la boucle fermée pour maintenir l'élément conducteur allongé à l'intérieur de l'élément isolant quelle que soit la position déformée ou non de la boucle.According to an advantageous embodiment, the connector comprises at least one protrusion protruding into the insulating element inside the closed loop to maintain the elongated conductive element inside the insulating element whatever the position. deformed or not the loop.

Selon une variante avantageuse, la (les) protubérance(s) est (sont) réalisée(s) par déformation à froid du matériau constitutif de l'élément isolant. Ainsi, selon cette variante, il suffit de réaliser un ou plusieurs piqués dans le matériau isolant, ou autrement dit un (des) poinçonnage(s) dans ce dernier, pour obtenir le maintien définitif de l'élément conducteur allongé. L'insertion préalable de l'extrémité libre de l'élément conducteur allongé permet le maintien momentané de la celle-ci dans l'isolant avant la réalisation du (des) piqué(s). Aucun moyen de fixation supplémentaire n'est nécessaire, ce qui réduit le nombre de pièces. Cela est d'autant plus avantageux pour un connecteur selon l'invention avec des faibles distances de carte-à-carte à connecter.According to an advantageous variant, the (the) protuberance (s) is (are) carried out (s) by cold deformation of the material constituting the insulating element. Thus, according to this variant, it suffices to make one or more stitches in the insulating material, or in other words punching (s) in the latter, to obtain the definitive retention of the elongate conductive element. The prior insertion of the free end of the elongate conductive element allows the momentary retention of the latter in the insulator before the realization of (the) stitch (s). No additional fastening is needed, which reduces the number of parts. This is all the more advantageous for a connector according to the invention with small card-to-card distances to be connected.

De préférence, l'élément isolant est en polyétheréthercétone (PEEK). Outre ses très bonnes propriétés d'isolation électrique, le PEEK a pour avantage de pouvoir être moulée et usiné aisément, ce qui est avantageux pour la réalisation de l'élément isolant selon l'invention.Preferably, the insulating element is made of polyetheretherketone (PEEK). In addition to its very good electrical insulation properties, the PEEK has the advantage of being able to be molded and machined easily, which is advantageous for the production of the insulating element according to the invention.

Selon une variante de réalisation avantageuse, l'élément isolant est maintenu à l'intérieur du corps tubulaire, de préférence par emmanchement en force, et l'extrémité libre de l'élément conducteur allongé en dehors de la boucle est apte à coulisser dans la fente de sorte à être alignée sur la deuxième extrémité quelle que soit la position déformée de la boucle. Au lieu d'un maintien de l'élément isolant à l'intérieur du corps tubulaire par emmanchement en force, on peut prévoir un maintien par clipsage.According to an advantageous variant embodiment, the insulating element is held inside the tubular body, preferably by force fitting, and the free end of the elongate conductive element outside the loop is able to slide in the slot so as to be aligned on the second end regardless of the distorted position of the loop. Instead of holding the insulating element inside the tubular body by force fitting, it can provide a clipping retention.

De préférence, l'élément isolant est maintenu à l'intérieur du corps tubulaire de sorte que son extrémité opposée à la fente débouchante soit alignée sur la première extrémité du corps.Preferably, the insulating member is held within the tubular body so that its end opposite the opening slot is aligned with the first end of the body.

Selon une variante alternative, l'élément isolant est monté à l'intérieur du corps tubulaire avec un jeu axial selon l'axe X, et l'extrémité libre de l'élément conducteur allongé en dehors de la boucle est fixée dans la fente de sorte à être alignée sur la deuxième extrémité quelle que soit la position déformée de la boucle.According to an alternative variant, the insulating element is mounted inside the tubular body with an axial clearance along the X axis, and the free end of the elongated conductive element outside the loop is fixed in the slot of so to be aligned on the second end regardless of the deformed position of the loop.

Selon une autre variante avantageuse, l'anneau ouvert comporte, à sa périphérie intérieure, une gorge définissant un épaulement de butée et le corps tubulaire comporte également, à sa périphérie extérieure, entre sa première extrémité et sa surface évasée, un épaulement de butée, les épaulements de l'anneau et du corps tubulaire coopérant par butée mutuelle pour maintenir l'anneau à l'extérieur du corps tubulaire dans sa position non déformée.According to another advantageous variant, the open ring comprises, at its inner periphery, a groove defining an abutment shoulder and the tubular body also comprises, at its outer periphery, between its first end and its flared surface, a stop shoulder, the shoulders of the ring and the tubular body cooperating by mutual abutment to maintain the ring outside the tubular body in its undeformed position.

L'anneau ouvert peut présenter une section constante sur toute sa périphérie ou présenter une section variable sur la périphérie. Une variante de réalisation avantageuse consiste à prévoir une section qui diminue au fur et à mesure que l'on se rapproche de l'ouverture (fente) de l'anneau. On peut ainsi homogénéiser le contact électrique sur toute la périphérie de l'anneau en tant que deuxième contact extérieur.The open ring may have a constant section over its entire periphery or have a variable section on the periphery. An advantageous embodiment consists in providing a section which decreases as one approaches the opening (slot) of the ring. It is thus possible to homogenize the electrical contact over the entire periphery of the ring as a second external contact.

De préférence, la surface évasée est de forme tronconique ou en arc de cercle. Selon une caractéristique avantageuse, l'élément conducteur allongé et l'anneau sont à base de cuivre béryllium (CuBe2).Preferably, the flared surface is frustoconical or arcuate. According to an advantageous characteristic, the elongated conductive element and the ring are based on beryllium copper (CuBe 2 ).

Avantageusement, le débattement (H0-Hm) entre la position non déformée et la position extrême déformée à la fois de l'anneau et de l'élément conducteur allongé est compris entre 0,1 et 0,4 mm.Advantageously, the displacement (H0-Hm) between the undeformed position and the extreme deformed position of both the ring and the elongate conductive element is between 0.1 and 0.4 mm.

Avantageusement encore, la hauteur du corps tubulaire, mesurée entre la première et la deuxième extrémité est inférieure à 2 mm.Advantageously, the height of the tubular body, measured between the first and the second end is less than 2 mm.

L'invention à également pour objet un procédé de réalisation selon l'objet de la revendication 11. Ce procédé permet de réaliser un connecteur coaxial hyperfréquence tel que décrit plus haut, procédé selon lequel on réalise les étapes suivantes :

  1. a/ montage avec maintien de l'élément conducteur allongé du contact central à l'intérieur de l'élément isolant, avec insertion préalable de l'extrémité libre dans la fente débouchante et avec formation au moins en partie de la boucle fermée ;
  2. b/ montage de l'élément isolant dans lequel est maintenu l'élément allongé, à l'intérieur du corps tubulaire du premier contact extérieur ;
  3. c/ montage avec maintien de l'anneau ouvert en tant que deuxième contact extérieur autour du corps tubulaire ;
  4. d/ réalisation finale de la boucle fermée telle qu'elle puisse être déformée jusqu'à sa position extrême alignée sur la première extrémité du corps tubulaire et coulissement de l'extrémité libre en dehors de la boucle jusqu'à ce qu'elle soit alignée sur la deuxième extrémité du corps tubulaire en faisant saillie de l'élément isolant.
The subject of the invention is also a production method according to the subject of claim 11. This method makes it possible to produce a microwave coaxial connector as described above, a method according to which the following steps are carried out:
  1. a / mounting with maintaining the elongated conductive element of the central contact inside the insulating element, with prior insertion of the free end into the open slot and with formation at least in part of the closed loop;
  2. b / mounting of the insulating element in which the elongated element is held, inside the tubular body of the first external contact;
  3. c / mounting with holding the ring open as a second outer contact around the tubular body;
  4. d / final embodiment of the closed loop such that it can be deformed to its extreme position aligned with the first end of the tubular body and sliding of the free end out of the loop until it is aligned on the second end of the tubular body protruding from the insulating member.

Les étapes b/ et c/ peuvent être réalisées successivement ou dans un ordre inverse.Steps b / and c / can be performed successively or in reverse order.

Lors de la réalisation de l'élément isolant, on s'assure que la hauteur de la fente débouchante dans l'élément isolant, c'est-à-dire sa dimension selon l'axe X du connecteur, est suffisante pour éviter tout pivotement et/ou pliage de l'élément conducteur allongé une fois celle-ci avec son extrémité libre alignée sur la deuxième extrémité du corps tubulaire constituant le contact de masse. Autrement dit, la hauteur de la fente dans l'élément isolant est suffisante pour assurer le maintien avec coulissement possible de l'extrémité libre de l'élément conducteur allongé, en dehors de la boucle et sans déformation plastique de l'extrémité libre.During the production of the insulating element, it is ensured that the height of the slot opening in the insulating element, that is to say its dimension along the X axis of the connector, is sufficient to prevent any pivoting. and / or folding the elongated conductive element once it has its free end aligned with the second end of the tubular body constituting the ground contact. In other words, the height of the slot in the insulating element is sufficient to ensure the possible retention of the free end of the elongated conductive element, outside the loop and without plastic deformation of the free end.

L'étape a/ est réalisée de préférence en formant au moins partiellement la boucle avec insertion préalable d'une extrémité libre dans la fente débouchante de l'élément isolant, puis réalisation de piqués, typiquement au nombre de deux en regard l'un de l'autre, dans le matériau isolant et à l'intérieur de la boucle pour maintenir celle-ci dans l'élément isolant. Dans cette réalisation, on prévoit un jeu suffisant j entre une portion de la boucle et l'élément isolant pour s'assurer qu'il n'y ait pas de contact mécanique entre eux.Step a / is preferably performed by at least partially forming the loop with prior insertion of a free end into the opening slot of the insulating element, then making dives, typically two in number one facing each other. the other, in the insulating material and inside the loop to maintain it in the insulating member. In this embodiment, sufficient clearance is provided between a portion of the loop and the insulating member to ensure that there is no mechanical contact between them.

L'étape b/ est réalisée de préférence avec maintien de l'élément isolant à l'intérieur du corps tubulaire, avantageusement par emmanchement en force de l'élément isolant dans le corps tubulaire.Step b / is preferably carried out with holding the insulating element inside the tubular body, advantageously by force fitting the insulating element into the tubular body.

L'étape c/ est réalisée de préférence par un simple élargissement de l'anneau au-delà du diamètre de l'épaulement de butée du corps tubulaire puis re-fermeture de l'anneau de sorte à avoir la mise en butée mutuelle de son épaulement défini par la gorge contre l'épaulement de butée du corps.Step c / is preferably performed by a simple widening of the ring beyond the diameter of the abutment shoulder of the tubular body and then re-closing the ring so as to have the mutual abutment of its shoulder defined by the groove against the abutment shoulder of the body.

L'étape d/ est réalisée avantageusement par simple compression de la boucle sur elle-même afin de la refermer.Step d / is advantageously performed by simply compressing the loop on itself in order to close it.

L'invention a enfin pour objet, selon encore un autre de ses aspects, un ensemble de circuit électrique comportant :

  • au moins un connecteur coaxial hyperfréquence tel que décrit précédemment,
  • deux cartes imprimées maintenues en parallèle l'une de l'autre d'une distance donnée, chacune des cartes comportant une première piste conductrice, dite piste centrale, et une deuxième piste conductrice, dite piste de masse,
dans lequel la connexion entre les pistes centrales est réalisée par l'élément conducteur allongé avec sa boucle fermée dans n'importe quelle position déformée jusqu'à sa position extrême déformée, tandis que la connexion entre les pistes de masse est réalisée par l'anneau dans n'importe quelle position déformée jusqu'à sa position extrême déformée.The invention finally provides, according to yet another of its aspects, an electrical circuit assembly comprising:
  • at least one microwave coaxial connector as described above,
  • two printed cards maintained in parallel with each other by a given distance, each of the cards comprising a first conducting track, called a central track, and a second conducting track, called a ground track,
wherein the connection between the central tracks is performed by the elongated conductive member with its closed loop in any deformed position to its distorted extreme position, while the connection between the ground tracks is performed by the ring in any deformed position to its extreme distorted position.

On a représenté sur la figure 1 un exemple de connecteur coaxial hyperfréquence 1 conforme à l'invention.We have shown on the figure 1 an example of a coaxial microwave connector 1 according to the invention.

Un connecteur coaxial hyperfréquence 1 selon l'invention est prévu pour relier deux cartes imprimées 6, 7, séparées d'une distance de carte à carte très faible, typiquement inférieure à 1,5 mm, avec des tolérances relativement importantes en valeur relative, typiquement égales à 0,2 mm.A microwave coaxial connector 1 according to the invention is provided for connecting two printed cards 6, 7, separated by a very small card-to-card distance, typically less than 1.5 mm, with relatively large tolerances in relative value, typically equal to 0.2 mm.

Dans toutes les configurations connectées des deux cartes 6, 7 entre elles, telles que celles illustrées en figure 2B, 4 et 5, des moyens de maintien mécanique non représentés et distincts du connecteur coaxial hyperfréquence 1 selon l'invention assurent le maintien à distance des deux cartes 6, 7 connectées entre elles.In all the connected configurations of the two cards 6, 7 between them, such as those illustrated in FIG. Figure 2B , 4 and 5, mechanical holding means not shown and distinct from the microwave coaxial connector 1 according to the invention ensure the remote maintenance of the two cards 6, 7 connected to each other.

Tel qu'illustré, un connecteur coaxial hyperfréquence 1 selon l'invention est constitué de quatre pièces, à savoir deux contacts extérieurs 2, 4 qui forment des contacts de masse, un contact central 3 et un élément isolant électriquement 5.As illustrated, a microwave coaxial connector 1 according to the invention consists of four parts, namely two external contacts 2, 4 which form ground contacts, a central contact 3 and an electrically insulating element 5.

Ainsi, le connecteur coaxial hyperfréquence 1 selon l'invention comporte tout d'abord en tant que premier contact extérieur, un corps tubulaire rigide 2, de révolution autour d'un axe longitudinal X.Thus, the microwave coaxial connector 1 according to the invention comprises firstly as a first external contact, a rigid tubular body 2, of revolution about a longitudinal axis X.

Ce corps 2 comporte une extrémité supérieure 21, une extrémité inférieure 22 opposée l'extrémité supérieure, et à sa périphérie extérieure, entre l'extrémité supérieure 21 et celle inférieure 22, une surface de contact 23 de forme évasée en arc de cercle vers l'extrémité inférieure 22. Le corps 2 est percé de part en part et présente ainsi une pluralité de sections circulaires intérieures dont une 2a de section constante depuis l'extrémité supérieure 21. Le corps 2 comporte en outre un épaulement de butée 24 entre son extrémité supérieure 21 et la surface de contact évasée 23.This body 2 has an upper end 21, a lower end 22 opposite the upper end, and at its outer periphery, between the upper end 21 and the lower end 22, a contact surface 23 of flared shape in a circular arc towards the upper end. The lower end 22. The body 2 is pierced from one side and thus has a plurality of inner circular sections, a constant section 2a from the upper end 21. The body 2 further comprises a stop shoulder 24 between its end. upper 21 and the flared contact surface 23.

Le connecteur coaxial hyperfréquence 1 comporte également un contact central comportant une lame 3 repliée en partie sur elle-même en définissant une boucle fermée 30, élastiquement déformable, avec une de ses extrémités libres 31 en dehors de la boucle.The coaxial microwave connector 1 also comprises a central contact having a blade 3 folded partially on itself by defining a closed loop 30, elastically deformable, with one of its free ends 31 outside the loop.

Le connecteur coaxial hyperfréquence 1 comporte en outre, en tant que deuxième contact extérieur un anneau 4 ouvert, élastiquement déformable. Cet anneau 4 ouvert, ou bague fendue, définit une fente 42. Il comporte intérieurement une gorge définissant un épaulement de butée 41 Dans le mode de réalisation illustré, la section de l'anneau 4 ouvert est constante sur toute sa périphérie. En variante, on pourrait prévoir une section variable avec une diminution à proximité de la fente 42, ce qui permet d'homogénéiser le contact électrique entre l'anneau 4 et les pistes conductrices de la carte ou composant électronique sur lequel il est en appui.The coaxial microwave connector 1 further comprises, as second external contact an open ring 4, elastically deformable. This open ring 4, or split ring, defines a slot 42. It internally comprises a groove defining a stop shoulder 41. In the illustrated embodiment, the section of the open ring 4 is constant over its entire periphery. Alternatively, a variable section with a decrease in the vicinity of the slot 42 could be provided, which makes it possible to homogenize the electrical contact between the ring 4 and the conductive tracks of the card or electronic component on which it is supported.

Le connecteur coaxial hyperfréquence 1 selon l'invention comporte enfin un élément isolant 5 comportant une fente 50 débouchante et allongée selon l'axe X, l'élément isolant étant agencé entre la lame 3 et le corps tubulaire 2. Plus précisément, tel qu'illustré sur l'ensemble des figures, l'élément isolant 5 est maintenu par emmanchement en force dans le corps tubulaire 2.The microwave coaxial connector 1 according to the invention finally comprises an insulating element 5 comprising a slot 50 opening and elongated along the X axis, the insulating element being arranged between the blade 3 and the tubular body 2. More specifically, such as illustrated in all the figures, the insulating element 5 is held by force fitting in the tubular body 2.

L'élément isolant 5 est de préférence en polyétheréthercétone PEEK.The blade 3 and the open ring 4 are preferably based on copper-beryllium (CuBe 2 ). The insulating element 5 is preferably polyetheretherketone PEEK.

A titre d'exemple, la lame 3 a une épaisseur égale à 0,07 mm pour une largeur de 0,6 mm.By way of example, the blade 3 has a thickness equal to 0.07 mm and a width of 0.6 mm.

A titre d'exemple également, le diamètre intérieur de l'extrémité inférieure 22 du corps 2 est égale à 3,3 mm tandis que le diamètre extérieur de cette extrémité inférieure est égale à 3,5mm.By way of example also, the inside diameter of the lower end 22 of the body 2 is equal to 3.3 mm while the outside diameter of this lower end is equal to 3.5 mm.

Comme illustré, le montage des différents éléments 2, 3, 4, 5 du connecteur coaxial 1 selon l'invention est prévu tel que

  • d'une part, la lame 3 est maintenue à l'intérieur de l'élément isolant 5 de sorte que la boucle fermée 30 puisse être déformée élastiquement par compression sur elle-même entre une position non déformée (figures 1, 1A, 2, 3 à 3B et 4A) dans laquelle son sommet 32 fait saillie au-delà de l'extrémité supérieure 21 du corps 2 et une position extrême déformée dans laquelle son sommet 32 est aligné sur l'extrémité supérieure, l'extrémité libre 31 de la lame 3 en dehors de la boucle étant apte à coulisser dans la fente 50 en faisant saillie de cette dernière et en étant alignée sur l'extrémité inférieure 22 quelle que soit la position déformée ou non de la boucle.
  • d'autre part, l'anneau 4 est maintenu à l'extérieur du corps tubulaire 2 de sorte qu'il puisse être déformé élastiquement par appui contre la surface évasée en arc de cercle 23 entre une position non déformée (figures 1, 1A, 2, 3 et 4A) dans laquelle il n'est pas en appui contre la surface évasée et son sommet 40 fait saillie au-delà de l'extrémité supérieure 21 et une position extrême déformée dans laquelle son sommet 40 est aligné sur l'extrémité supérieure 21.
As illustrated, the assembly of the various elements 2, 3, 4, 5 of the coaxial connector 1 according to the invention is provided such that
  • on the one hand, the blade 3 is kept inside the insulating element 5 so that the closed loop 30 can be deformed elastically by compression on itself between an undistorted position ( Figures 1, 1A , 2 , 3 to 3B and 4A ) in which its top 32 protrudes beyond the upper end 21 of the body 2 and a distorted extreme position in which its top 32 is aligned with the upper end, the free end 31 of the blade 3 outside of the loop being able to slide in the slot 50 projecting from the latter and being aligned with the lower end 22 regardless of the deformed position or not of the loop.
  • on the other hand, the ring 4 is held outside the tubular body 2 so that it can be deformed elastically by pressing against the flared surface in an arc of circle 23 between an undistorted position ( Figures 1, 1A , 2, 3 and 4A ) in which it does not bear against the flared surface and its top 40 projects beyond the upper end 21 and a distorted extreme position in which its top 40 is aligned with the upper end 21.

La figure 4A représente les positions non déformées de la lame 3 et de l'anneau ouvert 4, le connecteur coaxial 1 étant par ailleurs positionné sur la carte inférieure 7 des deux cartes 6, 7 de circuit imprimé à relier entre elles et l'autre carte 6 étant positionnée au-dessus du connecteur 1.The Figure 4A represents the undistorted positions of the blade 3 and the open ring 4, the coaxial connector 1 being furthermore positioned on the lower card 7 of the two printed circuit boards 6, 7 to be interconnected and the other card 6 being positioned above the connector 1.

Dans cette configuration non connectée, le positionnement du connecteur coaxial 1 est assuré de sorte à avoir l'extrémité libre 31 de la lame 3 positionnée en contact avec une piste conductrice 70, dite piste centrale, et l'extrémité inférieure 22 en contact avec une piste conductrice 71, dite piste de masse, de la carte 7.In this unconnected configuration, the positioning of the coaxial connector 1 is ensured so as to have the free end 31 of the blade 3 positioned in contact with a conductive track 70, called the central track, and the lower end 22 in contact with a conductive track 71, called ground track, of the map 7.

Par ailleurs, dans cette configuration, l'anneau ouvert 4 est maintenu par son épaulement de butée 41 en butée mutuel contre l'épaulement de butée 24 du corps 2. La boucle fermée en partie sur elle-même est quant à elle maintenue par deux piqués 51 en regard l'un de l'autre, réalisés par déformation à froid dans le matériau isolant constitutif de l'élément isolant 5.Furthermore, in this configuration, the open ring 4 is held by its abutment shoulder 41 in mutual abutment against the abutment shoulder 24 of the body 2. The closed loop partly on itself is maintained by two stitches 51 facing one another, made by cold deformation in the insulating material constituting the insulating element 5.

La figure 4B représente la position intermédiaire déformée à la fois de la lame 3 et de l'anneau ouvert 4.The Figure 4B represents the deformed intermediate position of both the blade 3 and the open ring 4.

Dans cette configuration connectée des deux cartes 6, 7 entre elles par le connecteur coaxial 1 selon l'invention, l'extrémité libre 31 de la lame 3 et l'extrémité inférieure 22 du corps restent en contact respectivement avec la piste centrale 70 et la piste de masse 71 de la carte inférieure 7, tandis que le sommet 32 de la boucle fermée 30 de la lame 3 est en contact avec la piste centrale 60 de la carte supérieure 6 et le sommet 40 de l'anneau 4 est en contact avec la piste de masse 61 de la carte supérieure.In this connected configuration of the two cards 6, 7 between them by the coaxial connector 1 according to the invention, the free end 31 of the blade 3 and the lower end 22 of the body remain in contact respectively with the central track 70 and the ground track 71 of the lower board 7, while the top 32 of the closed loop 30 of the blade 3 is in contact with the central track 60 of the upper board 6 and the top 40 of the ring 4 is in contact with the ground track 61 of the upper map.

Dans leurs positions extrêmes déformées non représentées, les sommets 32, 40 respectivement de la lame 3 et de l'anneau ouvert 4 sont alignés sur l'extrémité supérieure 21 du corps 2.In their extreme deformed positions not shown, the vertices 32, 40 respectively of the blade 3 and the open ring 4 are aligned on the upper end 21 of the body 2.

Tel qu'illustré en figure 4A, la hauteur Ho représente la distance maximale entre les sommets 32 et 40 respectivement de la lame 3 et de l'anneau ouvert 4 dans leurs positions non déformées. La hauteur Hi représente une distance intermédiaire de connexion entre les deux cartes de circuit imprimé 6, 7. Avantageusement, le débattement (H0-Hm) entre la position non déformée et la position extrême déformée à la fois de l'anneau et de la lame est compris entre 0,1 et 0,4 mm.As illustrated in Figure 4A , the height Ho represents the maximum distance between the vertices 32 and 40 respectively of the blade 3 and the open ring 4 in their undeformed positions. The height Hi represents an intermediate connection distance between the two printed circuit boards 6, 7. Advantageously, the deflection (H0-Hm) between the undeformed position and the extreme distorted position of both the ring and the blade. is between 0.1 and 0.4 mm.

A titre d'exemple, la hauteur H0 est de l'ordre de 1,7 mm et la hauteur Hm est proche de 1.3 mm.By way of example, the height H0 is of the order of 1.7 mm and the height Hm is close to 1.3 mm.

L'effort de contact axial selon l'axe X par retour élastique à la fois de la lame 3 et de l'anneau ouvert 4 assure un bon contact électrique respectivement avec les pistes centrales 60, 70 et les pistes de masse 61, 71 des deux cartes 6, 7 de circuit imprimé.The axial contact force along the axis X by elastic return of both the blade 3 and the open ring 4 ensures good electrical contact respectively with the central tracks 60, 70 and the ground tracks 61, 71 of the two cards 6, 7 of circuit board.

L'expression « comportant un » doit être comprise comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié.The expression "having one" shall be understood as being synonymous with "having at least one", unless the opposite is specified.
