Description

La présente invention est relative à un connecteur coaxial pour le raccordement d'un câble coaxial à une carte imprimée de circuit électronique.The present invention relates to a connector coaxial for connection of a coaxial cable to a printed electronic circuit board.

La mise en place de composants sur des cartes imprimées de circuits électroniques a été pendant longtemps réalisée à l'aide de picots prévus sur les composants et qui s'insèrent dans des trous métallisés de la carte.The installation of components on printed boards of electronic circuits has been for a long time made using pins provided on the components and which fit into metallized holes in the menu.

La fixation s'effectue par une opération de brasure à la bague permettant de fixer simultanément tous les composants à la carte.The fixing is carried out by a brazing operation with the ring allowing to simultaneously fix all the à la carte components.

Plus récemment, on a proposé de monter des composants sur des cartes imprimées de circuits électroniques par une technique dite "à montage en surface".More recently, it has been proposed to mount components on printed circuit boards by a technique called "surface mount".

Dans ce cas, l'on ne prévoit pas de trous traversants dans la carte, sauf le cas échéant pour établir des liaisons électriques entre différentes couches de circuits prévues sur la carte, et les composants sont munis à leur partie arrière de pattes plates qui sont brasées sur des plots prévus à la surface de la carte.In this case, no through holes are provided in the card, except where necessary to establish electrical connections between different layers of circuits provided on the card, and the components are provided at their rear part of flat legs which are brazed on studs provided on the surface of the card.

Cette technique permet de miniaturiser les cartes et d'automatiser les opérations de montage des composants sur les cartes.This technique makes it possible to miniaturize the cards and automate component assembly operations on the cards.

On a donc tout naturellement cherché à réaliser toutes sortes de composants miniaturisés, et notamment des connecteurs électriques, susceptibles d'être mis en place et fixés automatiquement sur des cartes imprimées, notamment par montage en surface.So we naturally tried to achieve all kinds of miniaturized components, and in particular electrical connectors, which can be automatically places and fixes on printed cards, especially by surface mounting.

Il est apparu que des problèmes se posent pour les connecteurs électriques destinés à relier un câble à la carte, notamment du fait que l'élément de connecteur monté sur la carte est amené à subir des contraintes mécaniques plus ou moins importantes lors des opérations d'accouplement et de désaccouplement, effectuées le plus souvent manuellement, avec l'élément de connecteur correspondant fixé au câble.It appeared that problems arise for electrical connectors for connecting a cable to the card, especially because the connector element mounted on the card is subject to mechanical stress more or less important during operations of coupling and uncoupling, carried out on more often manually, with the connector element corresponding attached to the cable.

Dans le cas d'un montage en surface les efforts d'accouplement et de désaccouplement se transmettent de manière importante sur les brasures et les plots de la carte. Pour éviter une rupture de la liaison de l'élément de connecteur fixé à la carte, on ajoute, la plupart du temps, à cet élément de connecteur des moyens de fixation mécaniques sur la carte, notamment de type vis-écrou. Ceci empêche une miniaturisation aussi poussée qu'on l'aurait voulu du connecteur et introduit une étape de montage supplémentaire, de telle sorte que le connecteur ne peut être fixé sur la carte lors du montage et de la fixation automatiques des autres composants.In the case of surface mounting, the coupling forces and uncoupling are transmitted from importantly on the solder and the studs of the menu. To avoid a break in the element's connection of connector attached to the card, we add, most of the time, to this connector element fixing means mechanical on the card, especially of the type screw nut. This prevents such extensive miniaturization that we wanted it from the connector and introduced a additional assembly step, so that the connector cannot be fixed on the card during mounting and the automatic fixing of the other components.

Or, dans les équipements modernes, il importe d'avoir des connecteurs, tels que des connecteurs coaxiaux, aussi miniaturisés que possible, aptes à être fabriqués en grande série de manière économique, et aptes à être mis en place et fixés de manière totalement automatique sur des cartes imprimées.However, in modern equipment, it is important to have connectors, such as connectors coaxial, as miniaturized as possible, suitable for mass produced economically, and able to be fully installed and fixed automatic on printed cards.

A titre d'application l'on peut citer les équipements de radiotéléponie mobiles portables tels que ceux de la nouvelle génération européenne GSM (Groupe Spécial Mobile) destinés à fonctionner à des fréquences de 900 MHz, et pour lesquels il importe de réaliser des connecteurs coaxiaux microminiatures pour assurer la liaison de câbles coaxiaux aux cartes imprimées de circuits électroniques dont sont munis les équipements. En outre le document EP-A- 419 938 décrit un connecteur selon le préambule de la revendication 1.As an application we can cite the equipment of portable mobile radio telephones such as those of the new European generation GSM (Special Group Mobile) intended to operate at frequencies of 900 MHz, and for which it is important to make connectors coaxial microminiatures to ensure the connection coaxial cables to printed circuit boards electronic equipment. In addition EP-A-419 938 describes a connector according to the preamble of claim 1.

La présente invention se propose de réaliser un connecteur coaxial pour la raccordement d'un câble coaxial à une carte imprimée de circuit électronique, se prêtant à une très grande miniaturisation tout en pouvant être réalisé avec peu d'éléments par des techniques de fabrication simples, le connecteur selon l'invention se prêtant en outre à une mise en place et une fixation automatiques sur la carte en même temps que les autres composants du fait qu'il ne nécessite pas de moyens mécaniques supplémentaires de fixation.The present invention proposes to provide a connector coaxial for connection of a coaxial cable to a printed circuit board, suitable for to a very large miniaturization while being able to be made with few elements by manufacturing techniques simple, the connector according to the invention is suitable in addition to automatic positioning and fixing on the map at the same time as the others components of the fact that it does not require mechanical means additional fixing.

De préférence, l'élément de connecteur destiné à être fixé àla carte imprimée et agencé en embase cylindrique, comporte un contact central femelle élastique, et l'autre élément de connecteur agencé en fiche et destiné à être fixé au câble coaxial, comporte un contact mâle en forme de broche, les moyens de verrouillage coopérants desdits contacts centraux étant constitués par un bourrelet intérieur du contact femelle apte à s'engager élastiquement dans une gorge de retenue prévue à la périphérie du contact mâle lors de l'engagement axial du contact mâle dans le contact femelle.means for fixing them to the end of a cable coaxial and respectively on a printed card and cooperating latching locking means, the connector element intended to be fixed to the printed board being arranged in a cylindrical base (1) comprising a ground contact, provided in one piece to its rear part of means (5) for fixing it to a printed card and a central contact (9) arranged in a central hole (8) with tubular insulation (6) and also provided in one piece, at its rear, means (12) for its attachment to said printed card, and the element connector intended to be fixed to the coaxial cable being arranged in plug (2) comprising a tubular part (16) connection at the end of a coaxial cable and a tubular coupling part (15) comprising a cylindrical outer sleeve forming ground contact (22), and a central contact (26) comprising at its part rear connection means (27) for the conductor central (17) of the coaxial cable, and immobilized in a tubular insulator (23) retained in said outer sleeve (22), said connector being characterized by the fact that the ground contact of the connector element arranged as a base (1) is an outer sleeve (3) radially elastic over at least part of its height and around which the outer sleeve engages cylindrical (22) of the connector element arranged in plug (2) and that said central contacts of the two elements connector comprise said locking means by cooperating snap-in. Preferably, the connector element intended to be fixed to the printed circuit board and arranged in a cylindrical base, includes a elastic female central contact, and the other element of connector arranged in plug and intended to be fixed to the cable coaxial, has a pin-shaped male contact, the cooperating locking means of said contacts central being formed by an inner bead of the female contact capable of engaging elastically in a retaining groove provided at the periphery of the contact male during axial engagement of the male contact in the female contact.

Dans un mode particulier de réalisation, le contact femelle est réalisé sous la forme d'une pièce de section sensiblement en forme de U retenue par sa partie arrière dans le trou central de l'isolant tubulaire dans lequel elle est montée, et dont les deux branches élastiques sont inclinées légèrement l'une vers l'autre en direction de leur extrémité libre, et comportent chacune une partie d'extrémité repliée vers l'intérieur en direction de l'autre branche. Les parties d'extrémité repliées des deux branches constituent le bourrelet intérieur de contact femelle apte às'engager dans la gorge de retenue périphérique du contact mâle correspondant.In a particular embodiment, the contact female is made in the form of a section piece substantially U-shaped retained by its rear part in the central hole of the tubular insulation in which it is mounted, and the two elastic branches of which are tilted slightly towards each other towards their free end, and each have a part end folded inward towards the other plugged. The folded end portions of the two arms constitute the internal bead of female contact able to engage in the peripheral retaining groove of the corresponding male contact.

Pour son raccordement et sa fixation à la carte imprimée, le contact femelle, dans ce mode de réalisation, comporte avantageusement à sa partie arrière une patte d'un seul tenant avec l'âme reliant les deux branches élastiques, ladite patte étant repliée à 90° vers l'extérieur par rapport à l'axe de l'élément de connecteur dans lequel est monté le contact femelle.For its connection and fixing to the printed board, the female contact, in this embodiment, advantageously has at its rear part a tab in one piece with the soul connecting the two branches elastic, said tab being folded 90 ° outwards with respect to the axis of the connector element in which is mounted the female contact.

La douille extérieure formant contact de masse de l'élément de connecteur agencé en embase et destiné à être fixé à la carte imprimée comporte avantageusement, sur une partie de sa hauteur, au moins une languette élastique découpée faisant saillie radialement vers l'extérieur de ladite douille à l'état désassemblé du connecteur.The outer sleeve forming the ground contact of the connector element arranged as a base and intended for to be attached to the printed card advantageously comprises, over part of its height, at least one tongue cut out elastic projecting radially towards the outside of said socket in the disassembled state of connector.

La ou les languettes élastiques sont comprimées radialement lors de la mise en place de la douille extérieure formant contact de masse de l'élément de connecteur complémentaire, ce qui assure un excellent contact électrique entre les contacts de masse des deux éléments de connecteur.The elastic tab (s) are compressed radially when fitting the outer sleeve forming ground contact of the connector element complementary, which ensures excellent electrical contact between the earth contacts of the two elements connector.

La douille extérieure formant contact de masse de l'élément de connecteur agencé en embase comporte avantageusement pour sa fixation et son raccordement à la carte imprimée une pluralité de pattes repliées vers l'extérieur par rapport à la douille extérieure dans le même plan à 90° par rapport à l'axe de ladite douille.The outer sleeve forming the ground contact of the connector element arranged as a base comprises advantageously for its fixing and its connection on the printed card a plurality of legs folded towards the outside relative to the outside socket in the same plane at 90 ° relative to the axis of said socket.

Ainsi, l'élément de connecteur agencé en embase et comportant les différentes pattes mentionnées ci-dessus prolongeant respectivement le contact central et le contact de masse peut être fixé en surface sur une carte imprimée de circuit électronique.Thus, the connector element arranged as a base and with the different legs mentioned above extending the central contact and the ground contact can be surface mounted on a card printed circuit board.

A cet effet, de façon conventionnelle on dépose par sérigraphie de la crème à braser sur les plots prévus sur la carte, on pose l'élément de connecteur agencé en embase ainsi que les autres composants à fixer sur la carte et on provoque la refusion de la crème à braser par chauffage infra-rouge ou en phase vapeur.For this purpose, conventionally, deposit by brazing cream screen printing on the pads provided on the card, we put the connector element arranged as a base as well as the other components to be fixed on the card and we cause the solder cream to melt again infrared or vapor heating.

Pour un positionnement sans erreur de l'élément de connecteur agencé en embase, les pattes à braser, réalisées d'un seul tenant avec la douille extérieure formant contact de masse, sont de préférence différentes d'une patte prolongeant le contact élastique central. Ainsi par exemple la patte du contact central peut présenter des chanfreins d'extrémité.For error-free positioning of the element connector arranged as a base, the legs to be brazed, made in one piece with the outer sleeve forming ground contact, are preferably different from one tab extending the central elastic contact. So by example the tab of the central contact may have end chamfers.

L'élément de connecteur agencé en embase selon l'invention est ainsi avantageusement constitué de trois pièces seulement pouvant être fabriquées par des techniques simples. On peut selon l'invention réaliser dans des conditions économiques un élément de connecteur microminiature, c'est-à-dire dans la pratique pouvant présenter une hauteur de l'ordre de 2 mm.The connector element arranged as a base according to the invention thus advantageously consists of three parts only capable of being manufactured by techniques simple. According to the invention, it is possible to carry out in economic conditions a connector element microminiature, that is to say in practice that can have a height of the order of 2 mm.

En effet l'élément de connecteur agencé en embase comporte comme indiqué ci-dessus une douille extérieure qui peut être réalisée de façon économique par découpe et roulage d'une tôle, par exemple en alliage cuivreux, un isolant de forme simple qui peut être réalisé par moulage, et un contact central qui peut être réalisé par découpe et cambrage d'une tôle en alliage cuivreux.Indeed the connector element arranged as a base as indicated above, has an external socket which can be produced economically by cutting and rolling of a sheet, for example of copper alloy, a simple form of insulation that can be made by molding, and a central contact which can be produced by cutting and bending a sheet of copper alloy.

L'autre élément de connecteur agencé en fiche et destiné à être monté à l'extrémité d'un câble coaxial, est de préférence de forme coudée et sa partie tubulaire de raccordement à l'extrémité du câble coaxial est disposée à angle droit par rapport à la partie tubulaire d'accouplement, et de préférence réalisée d'un seul tenant avec elle.The other connector element arranged in plug and intended to be mounted at the end of a coaxial cable, is preferably angled and its tubular part of connection at the end of the coaxial cable is arranged at right angles to the tubular coupling part, and preferably made in one piece with she.

L'extrémité arrière de la douille extérieure de la partie d'accouplement est munie d'un élément d'obturation mis en place après réalisation du raccordement au câble coaxial, l'élément d'obturation étant, soit un couvercle rapporté, soit une partie rabattue de la paroi de la douille extérieure.The rear end of the outer sleeve of the part coupling is provided with a sealing element installed after connection to cable coaxial, the closure element being either a cover reported, or a folded part of the wall of the socket outside.

L'élément de connecteur agencé en fiche peut, de même que l'autre élément de connecteur, être réalisé en grande série par des procédés économiques.The plug-in connector element can, same as the other connector element, be made in large series by economical processes.

Ainsi, l'élément de connecteur agencé en fiche peut être constitué de seulement trois pièces, à savoir un corps comportant la douille extérieure de la partie d'accouplement et la partie tubulaire de raccordement au câble, ce corps pouvant être réalisé par moulage notamment d'un alliage zinc/aluminium, un contact central réalisé par usinage et un isolant réalisé par moulage.Thus, the connector element arranged in plug can consist of only three parts, namely a body comprising the outer sleeve of the coupling part and the tubular part for connection to the cable, this body can be produced by molding in particular a zinc / aluminum alloy, a central contact made by machining and an insulator produced by molding.

Dans le cas où ce n'est pas un élément de paroi qui est utilisé pour obturer l'extrémité arrière de la douille extérieure, l'élément de connecteur agencé en fiche comporte un couvercle en tant que quatrième pièce, le couvercle pouvant également être réalisé de manière simple et économique.In the event that it is not a wall element which is used to seal the rear end of the outer sleeve, the connector element arranged in plug comprises a cover as a fourth piece, the cover can also be done in a simple way and economical.

Le connecteur selon l'invention comprend un élément de connecteur agencé en embase, désigné globalement par 1, destiné à être fixé à sa partie arrière sur une carte imprimée de circuit électronique (non représentée et un élément de connecteur, désigné globalement par 2 et agencé en fiche fixée à l'extrémité d'un câble coaxial, comme illustré aux figures 1 et 2.The connector according to the invention comprises an element of connector arranged in base, designated overall by 1, intended to be fixed to its rear part on a printed electronic circuit board (not shown and a connector element, generally designated by 2 and arranged in plug attached to the end of a coaxial cable, as shown in Figures 1 and 2.

On va maintenant décrire tout d'abord l'embase 1 en se référant plus particulièrement aux figures 3 à 8.We will now first describe the base 1 with particular reference to Figures 3 to 8.

L'embase 1 comporte une douille métallique cylindrique 3 dans laquelle sont découpées deux languettes élastiques 4, s'étendant sur une partie de la hauteur de la douille et faisant radialement saillie de sa périphérie.The base 1 includes a cylindrical metal socket 3 from which two tongues are cut elastic 4, extending over part of the height of the socket and projecting radially from its periphery.

A sa partie arrière, la douille 3 se prolonge par trois pattes 5 cambrées dans le même plan à 90° vers l'extérieur par rapport à la douille 3.At its rear part, the socket 3 is extended by three legs 5 arched in the same plane at 90 ° outwards relative to socket 3.

A l'intérieur de la douille cylindrique 3 est logé un isolant tubulaire cylindrique 6 comportant un tronçon cylindrique avant 6a monté à ajustement serré dans la douille 3 et un tronçon arrière de plus grand diamètre 6b comportant trois encoches axiales 7 pour le passage des pattes 5.Inside the cylindrical socket 3 is housed a cylindrical tubular insulator 6 comprising a front cylindrical section 6 has fitted snugly in the socket 3 and a rear section of larger diameter 6b comprising three axial notches 7 for the passage of the legs 5.

A l'intérieur du trou central 8 de l'isolant 6, est monté un contact central femelle 9 qui, comme on le voit le mieux sur la figure 3, est constitué d'une pièce de section sensiblement en U comportant deux branches élastiques 10 reliées à leur partie arrière par une âme 11 prolongée par une patte 12 s'étendant radialement vers l'extérieur.Inside the central hole 8 of the insulation 6, is mounted a female central contact 9 which, as seen in the better in Figure 3, consists of a section piece substantially U-shaped with two elastic arms 10 connected to their rear part by an extended core 11 by a tab 12 extending radially outward.

Comme on le voit sur les figures 6 et 8 l'extrémité de la patte 12 présente deux chanfreins d'extrémité 13 constituant des moyens de détrompage pour la distinguer des pattes 5 en vue d'un positionnement de l'embase sur la carte.As seen in Figures 6 and 8 the end of lug 12 has two end chamfers 13 constituting means of polarization to distinguish it tabs 5 for positioning the base on the map.

Les branches élastiques 10 sont dans leur partie arrière montées à ajustement serré dans le trou 8 de l'isolant 6 et sont inclinées l'une vers l'autre en direction de leur extrémité avant libre pour pouvoir s'écarter élastiquement lors de l'engagement d'un contact mâle correspondant.The elastic branches 10 are in their rear part fitted tightly in hole 8 of insulation 6 and are inclined towards each other in the direction of their free front end to be able to deviate elastically when engaging a corresponding male contact.

Les extrémités 14 des branches 10 sont repliées en direction l'une de l'autre de manière à constituer un bourrelet intérieur.The ends 14 of the arms 10 are folded in direction of each other so as to constitute a bead interior.

Les pattes 5 et 12 sont destinées à être brasées par leur face d'extrémité sur des plots correspondants d'une carte imprimée de circuit électronique.The legs 5 and 12 are intended to be brazed by their end face on corresponding studs of a printed electronic circuit board.

Du fait qu'une certaine distance axiale (e, figure 7) correspondant à la hauteur du tronçon 6b de l'isolant sépare l'extrémité arrière de la douille de contact de masse 3 de la patte 12 prolongeant le contact central, on assure un bon isolement électrique entre le contact de masse et le contact central.Because a certain axial distance ( e , FIG. 7) corresponding to the height of the section 6b of the insulation separates the rear end of the ground contact socket 3 from the tab 12 extending the central contact, a good electrical insulation between the earth contact and the central contact.

On va maintenant décrire en se référant aux figures 1 et 2, l'élément de connecteur complémentaire agencé en fiche 2.We will now describe with reference to the figures 1 and 2, the complementary connector element arranged in sheet 2.

La fiche 2 comporte une partie tubulaire 15 d'accouplement à l'embase et une partie tubulaire 16 pour le raccordement d'un câble coaxial.The plug 2 comprises a tubular coupling part 15 to the base and a tubular part 16 for connection coaxial cable.

Dans l'exemple illustré, la fiche 2 est coudée et la partie de raccordement 16 s'étend à angle droit par rapport à la partie d'accouplement 15, ce qui permet une arrivée de câble coaxial parallèle à la carte imprimée.In the example illustrated, plug 2 is bent and the connection part 16 extends at right angles to relative to the coupling part 15, which allows a arrival of coaxial cable parallel to the printed board.

Le câble coaxial comporte de manière conventionnelle un conducteur central 17 séparé par un isolant 18 d'une tresse 19 formant contact de masse et entourée par une gaine de protection extérieure 20.The coaxial cable comprises in a conventional manner a central conductor 17 separated by an insulator 18 of a braid 19 forming ground contact and surrounded by an external protective sheath 20.

La partie de raccordement 16 comporte un manchon tubulaire 21 au contact duquel est amenée l'extrémité dénudée du conducteur de masse 19 du câble pour y être fixée par brasure ou sertissage.The connection part 16 includes a sleeve tubular 21 in contact with which the end is brought stripped of the ground conductor 19 of the cable for y be fixed by soldering or crimping.

La partie d'accouplement 15 comporte une douille cylindrique 22 d'un seul tenant avec le manchon 21 et apte à s'engager sur la douille 3 de l'embase 1.The coupling part 15 comprises a socket cylindrical 22 in one piece with the sleeve 21 and able to engage on the socket 3 of the base 1.

A l'intérieur de la douille 22 est engagé un isolant tubulaire 23 pourvu à sa périphérie d'une gorge 24 pour sa retenue sur un bourrelet interne 25 réalisé dans la paroi de la douille 22.Inside the sleeve 22 is engaged an insulator tubular 23 provided at its periphery with a groove 24 for its retention on an internal bead 25 produced in the wall of the socket 22.

Un contact central 26 est logé dans la douille 22 en étant immobilisé dans l'isolant 23. Ce contact est cylindrique et comporte à son extrémité arrière une fente 27 dans laquelle s'engage l'extrémité dénudée du conducteur central 17 du câble pour y être immobilisé par brasure ou sertissage.A central contact 26 is housed in the socket 22 in being immobilized in the insulator 23. This contact is cylindrical and has at its rear end a slot 27 in which the stripped end of the conductor engages central 17 of the cable to be immobilized therein by soldering or crimping.

Le contact 26 comporte une partie en forme de harpon 28 pour son immobilisation dans l'isolant 23.Contact 26 has a harpoon-shaped part 28 for its immobilization in the insulation 23.

Le contact 26 comporte en outre une partie de tête effilée 29 apte à être introduite entre les branches 10 du contact femelle en écartant celles-ci.Contact 26 further includes a head portion tapered 29 able to be introduced between the branches 10 of the female contact by removing them.

La partie de tête 29 comporte une extrémité tronconique prolongée par une partie cylindrique elle-même raccordée par une courte partie de transition à une partie de diamètre réduit 30 qui réalise une gorge entre la partie d'extrémité 29 et la partie du contact 26 retenue dans l'isolant 23.The head portion 29 has a frustoconical end extended by a cylindrical part itself connected by a short transition part to a part of reduced diameter 30 which makes a groove between the part end 29 and the part of contact 26 retained in insulation 23.

L'extrémité arrière de la douille 22 est, après fixation de la fiche sur le câble, obturée par un couvercle 31.The rear end of the socket 22 is, after fixing of the plug on the cable, closed by a cover 31.

Dans la variante de réalisation illustrée à la figure 9, l'obturation de l'extrémité supérieure de la douille 22 s'effectue par rabattement d'un élément de paroi 32 réalisé d'un seul tenant avec la douille 22.In the variant embodiment illustrated in FIG. 9, the upper end of the socket 22 is closed by folding down a wall element 32 produced in one piece with socket 22.

Lors de la réalisation de la connexion des deux éléments de connecteur 1 et 2, la partie de tête 29 du contact central 26 de la fiche 2 s'insère entre les branches 10 du contact central 9 de l'embase 1, écarte élastiquement ces branches qui, après passage de la tête, reviennent élastiquement de telle sorte que leurs extrémités recourbées 14 viennent s'engager par encliquetage dans la gorge 30 du contact 26.When making the connection of the two elements connector 1 and 2, the head portion 29 of the contact central 26 of file 2 is inserted between the branches 10 of the central contact 9 of the base 1, elastically spreads these branches which, after passing the head, return elastically so that their ends curved 14 engage by snap-fastening in the groove 30 of the contact 26.

On réalise ainsi, au niveau des contacts centraux des éléments de connecteur, un verrouillage par encliquetage. Un contact est simultanément réalisé entre les douilles extérieures respectives 22 de la fiche 2, et 3 de l'embase 1 par appui de la douille 22 sur les languettes élastiques 4 de la douille 3.We thus realize, at the level of the central contacts connector elements, snap lock. Contact is simultaneously made between the respective outer sockets 22 of plug 2, and 3 of the base 1 by pressing the socket 22 on the tabs sleeve 4 elastic 3.

La conception des éléments de connecteur selon l'invention permet une séparation des deux éléments de connecteur sans exercer d'efforts notables sur l'embase qui pourraient provoquer une désolidarisation de celle-ci de la carte, en rendant ainsi inutile tout moyen mécanique de fixation de l'embase sur la carte. L'effort d'extraction peut être minimisé par une conformation appropriée des extrémités repliées 14 des branches 10 du contact central de l'embase et de la partie de transition sur le contact mâle 26 entre la partie d'extrémité 29 et la partie de diamètre réduit formant gorge de retenue 30. En particulier, l'élément de connecteur agencé en embase peut être muni d'autres moyens, tels que des picots pour sa fixation à la carte imprimée de circuit électronique.The design of the connector elements according to the invention allows a separation of the two elements of connector without exerting significant efforts on the base which could cause a separation of the latter of the card, thus making any mechanical means unnecessary fixing the base on the card. The extraction effort can be minimized by appropriate conformation folded ends 14 of branches 10 of contact central of the base and the transition part on the male contact 26 between the end part 29 and the part of reduced diameter forming retaining groove 30. In particular, the connector element arranged as a base can be provided with other means, such as pins for its fixing to the printed circuit board.
