Description

La présente invention concerne un connecteur électrique pour le raccordement d'une carte à circuit(s) intégré(s) à contact avec un dispositif, notamment de lecture-écriture, comportant un circuit d'exploitation des données contenues dans la carte et au moins une plaque à circuit imprimé dont la face supérieure comporte des pistes conductrices et sur laquelle est monté le connecteur.The present invention relates to an electrical connector for connecting an integrated circuit card (s) in contact with a device, in particular a read-write device, comprising a circuit for processing the data contained in the card and at least a printed circuit board whose upper face has conductive tracks and on which the connector is mounted.

On connaît différentes conceptions d'un connecteur électrique pour le raccordement d'une carte à circuit(s) intégré(s) à contact, également appelée carte à mémoire électronique ou carte à puce, du type dans lequel le connecteur comporte un corps ou support en matériau isolant qui porte des éléments de contact électrique qui font saillie au-dessus d'une face supérieure de contact du corps du connecteur pour coopérer avec des plages de contact électrique alignées sur une face principale de la carte qui, en position active, s'étend au-dessus de la face supérieure du corps du connecteur.There are known different designs of an electrical connector for the connection of an integrated circuit circuit board (s) with contact, also called electronic memory card or smart card, of the type in which the connector comprises a body or support. of insulating material which carries electrical contact elements which protrude above an upper contact face of the connector body to cooperate with electrical contact pads aligned on a main face of the card which, in the active position, s 'extends above the upper side of the connector body.

Pour assurer le raccordement électrique entre les plages de la carte et les pistes conductrices de la plaque à circuit imprimé, chaque élément de contact du connecteur est réalisé sous la forme d'une lame pliée comportant un tronçon intermédiaire de fixation de la lame sur le corps qui se prolonge, d'une part, par un tronçon d'extrémité de contact dont une partie incurvée de contact fait saillie au-dessus de la face supérieure du corps et, d'autre part, par un tronçon d'extrémité de raccordement qui, lorsque la face inférieure du corps du connecteur est en appui sur la face supérieure de la plaque à circuit imprimé du dispositif équipé du connecteur, est relié à une piste conductrice.To ensure the electrical connection between the areas of the card and the conductive tracks of the printed circuit board, each contact element of the connector is produced in the form of a folded blade comprising an intermediate section for fixing the blade to the body. which is extended, on the one hand, by a contact end section of which a curved contact part projects above the upper face of the body and, on the other hand, by a connection end section which , when the lower face of the connector body is supported on the upper face of the printed circuit board of the device equipped with the connector, is connected to a conductive track.

Afin de faciliter le montage du connecteur sur la plaque à circuit imprimé selon un agencement dans lequel le connecteur peut être implanté aisément en le fixant sur la plaque comme tout autre composant électronique, il a déjà été proposé dans la demande internationale PCT/FR 95/00959, un agencement comportant un boîtier fixé sur la face de la plaque à circuit imprimé, qui comporte un logement qui reçoit le corps du connecteur électrique et du type dans lequel les bornes ou extrémités de raccordement des lames de contact du connecteur sont en contact avec les pistes conductrices formées sur la plaque à circuit imprimé.In order to facilitate the mounting of the connector on the printed circuit board according to an arrangement in which the connector can be easily installed by fixing it to the board like any other electronic component, it has already been proposed in international application PCT / FR 95 / 00959, an arrangement comprising a housing fixed to the face of the printed circuit board, which comprises a housing which receives the body of the electrical connector and of the type in which the terminals or connection ends of the contact blades of the connector are in contact with the conductive tracks formed on the printed circuit board.

L'agencement décrit dans ce document propose d'assurer la liaison ou raccordement électrique des extrémités de raccordement en "pinçant" les branches de raccordement entre la face de la plaque à circuit imprimé comportant les pistes conductrices et la face en vis-à-vis d'une plaque supérieure du boîtier.The arrangement described in this document proposes to ensure the electrical connection or connection of the connection ends by "pinching" the connecting branches between the face of the printed circuit board comprising the conductive tracks and the face opposite. an upper plate of the housing.

Cette conception permet de réduire de manière importante la hauteur totale de l'ensemble plaque à circuit imprimé-connecteur et boîtier, mais elle est encombrante en ce que le connecteur, avec ses moyens de fixation sur la plaque, occupe une surface importante de cette dernière.This design makes it possible to significantly reduce the total height of the printed circuit board-connector and housing assembly, but it is bulky in that the connector, with its means of attachment to the plate, occupies a large surface of the latter. .

De plus, la qualité du contact ou liaison électrique entre les bornes de raccordement et les pistes conductrices de la plaque à circuit imprimé peut être insuffisante.In addition, the quality of the electrical contact or connection between the connection terminals and the conductive tracks of the printed circuit board may be insufficient.

On a représenté sur la figure 1 un agencement pour le raccordement d'une carte C à circuit(s) intégré(s) à contact avec un circuit d'exploitation appartenant à un dispositif, par exemple de lecture-écriture, comportant notamment une plaque à circuit imprimé 10.FIG. 1 shows an arrangement for the connection of a card C with integrated circuit (s) in contact with an operating circuit belonging to a device, for example of read-write, comprising in particular a plate with printed circuit 10.

La face principale 12, inférieure en considérant la figure 1, de la carte C comporte, selon une conception connue, des plages conductrices alignées reliées au circuit intégré de la carte tandis que la face supérieure 14 de la plaque 10 comporte des pistes conductrices reliées notamment au circuit d'exploitation.The main face 12, lower when considering FIG. 1, of the card C comprises, according to a known design, aligned conductive pads connected to the integrated circuit of the card while the upper face 14 of the plate 10 comprises conductive tracks connected in particular to the operating circuit.

Le raccordement de la carte C, lorsque cette dernière est dans une position active d'exploitation des données contenues dans sa mémoire, est assuré au moyen d'un connecteur électrique 16 qui est monté dans un boîtier de protection, et notamment de blindage, 18.The connection of card C, when the latter is in an active position for processing the data contained in its memory, is ensured by means of a electrical connector 16 which is mounted in a protective housing, and in particular a shielding housing, 18.

Le connecteur 16 est constitué pour l'essentiel par un corps en matériau isolant 20 qui, dans le mode de réalisation illustré sur les figures, est réalisé en deux parties 22 et 24.The connector 16 essentially consists of a body of insulating material 20 which, in the embodiment illustrated in the figures, is made in two parts 22 and 24.

Comme on peut le voir en se reportant aux figures 3 à 8, la partie inférieure 22 constitue un support pour le montage et la fixation de lames conductrices de raccordement électrique alignées par paires 26, 26' tandis que la partie 24, supérieure en considérant notamment la figure 8, constitue un couvercle du support 22.As can be seen by referring to FIGS. 3 to 8, the lower part 22 constitutes a support for the mounting and fixing of conductive electrical connection blades aligned in pairs 26, 26 ′ while the upper part 24, considering in particular FIG. 8 constitutes a cover for the support 22.

Selon une conception connue qui est par exemple décrite et représentée dans le document WO-A-95/18421, chaque lame de contact 26 est une lame en matériau conducteur réalisé par un découpage, pliage et cambrage qui comporte un tronçon ou branche intermédiaire de fixation 28 qui permet le montage de la lame sur le support 22.According to a known design which is for example described and represented in document WO-A-95/18421, each contact blade 26 is a blade of conductive material produced by cutting, folding and bending which comprises an intermediate section or branch for fixing 28 which allows the mounting of the blade on the support 22.

Le tronçon intermédiaire 28 se prolonge par un tronçon d'extrémité de contact 30 qui comporte, au voisinage de son extrémité libre 32, une partie incurvée de contact 34 qui fait normalement saillie verticalement au-dessus de la face supérieure plane 36 du couvercle 24.The intermediate section 28 is extended by a contact end section 30 which comprises, in the vicinity of its free end 32, a curved contact part 34 which normally projects vertically above the planar upper face 36 of the cover 24.

Dans le mode de réalisation illustré sur les figures, le tronçon d'extrémité de contact 30 est relié au tronçon de fixation 28 par un coude 38 déformable élastiquement, du fait de l'élasticité propre du matériau dans lequel sont réalisées les lames 26, qui confère au tronçon de contact 30 une grande élasticité et un effort important de contact lorsque la carte C, comme on peut le voir sur la figure 1, est amenée en position active au-dessus de la face supérieure 36, par exemple en lui appliquant un effort vertical selon la flèche F pour faire fléchir et pivoter les branches de contact 30 et assurer le meilleur contact électrique possible entre les parties incurvées 34 et les plages alignées de la face inférieure 12 de la carte C.In the embodiment illustrated in the figures, the contact end section 30 is connected to the fixing section 28 by a bend 38 elastically deformable, due to the inherent elasticity of the material from which the blades 26 are made, which gives the contact section 30 great elasticity and a significant contact force when the card C, as can be seen in FIG. 1, is brought into the active position above the upper face 36, for example by applying a vertical force according to arrow F to bend and pivot the contact branches 30 and ensure the best possible electrical contact between the curved parts 34 and the aligned areas of the lower face 12 of the card C.

La position d'origine des branches 30 est déterminée par la coopération de l'extrémité libre en forme de bec 32 de chaque lame 26 avec une surface de butée en vis-à-vis 40 formée dans la fenêtre correspondante 42 du couvercle 24.The original position of the branches 30 is determined by the cooperation of the free end in the shape of a beak 32 of each blade 26 with a facing abutment surface 40 formed in the corresponding window 42 of the cover 24.

Le tronçon intermédiaire de fixation 28 se prolonge, à l'opposé du tronçon d'extrémité de contact 30, par un tronçon d'extrémité de raccordement 44 qui, dans ce mode de réalisation de l'invention, est réalisé sous la forme d'une branche de raccordement 46, 46' qui s'étend depuis l'extrémité 49 du tronçon intermédiaire de fixation 28 opposée à l'extrémité 51 de ce dernier qui est prolongée par la branche de contact 30.The intermediate fixing section 28 is extended, opposite the contact end section 30, by a connection end section 44 which, in this embodiment of the invention, is produced in the form of a connection branch 46, 46 ′ which extends from the end 49 of the intermediate fixing section 28 opposite the end 51 of the latter which is extended by the contact branch 30.

La branche de raccordement 46, 46' est inclinée par rapport à la branche intermédiaire de liaison 28 qui s'étend parallèlement à la face supérieure 36 ainsi qu'à la face inférieure parallèle 48.The connecting branch 46, 46 ′ is inclined relative to the intermediate connecting branch 28 which extends parallel to the upper face 36 as well as to the parallel lower face 48.

La branche de raccordement 46 est reliée à la branche de liaison 28 par un coude 50 déformable élastiquement qui constitue une zone d'articulation pour la branche 46 qui est susceptible de pivoter autour d'un axe d'articulation X-X, sensiblement parallèle aux faces 36 et 48.The connecting branch 46 is connected to the connecting branch 28 by an elastically deformable elbow 50 which constitutes an articulation zone for the branch 46 which is capable of pivoting around an articulation axis XX, substantially parallel to the faces 36 and 48.

La branche 46 s'étend dans un logement 52 formé dans la face inférieure 48 du support 22 et qui est délimité par une face supérieure interne 55 et à l'intérieur duquel elle peut être déformée élastiquement par rapport à sa position d'origine illustrée en trait plein sur la figure 8 dans laquelle l'extrémité libre en forme de bec 54 de la branche de raccordement est en appui contre une face supérieure interne 56 d'une patte de retenue 58 réalisée sous la forme d'une traverse qui s'étend dans le logement 52 et dans le plan de la face inférieure 48 du support 22.The branch 46 extends in a housing 52 formed in the lower face 48 of the support 22 and which is delimited by an internal upper face 55 and inside which it can be elastically deformed relative to its original position illustrated in solid line in FIG. 8 in which the beak-shaped free end 54 of the connecting branch is in abutment against an internal upper face 56 of a tab retainer 58 produced in the form of a crosspiece which extends in the housing 52 and in the plane of the lower face 48 of the support 22.

L'extrémité en forme de bec de retenue 54 s'étend horizontalement et elle est sollicitée élastiquement en appui, du fait de l'élasticité propre de la branche de raccordement 46, contre la surface de butée 56.The end in the shape of a retaining spout 54 extends horizontally and it is elastically urged to bear, due to the inherent elasticity of the connecting branch 46, against the abutment surface 56.

Comme on peut le voir sur la figure 8, le couvercle 24 est constitué pour l'essentiel par une plaque supérieure 60 ajourée par les fenêtres 42 et par une jupe latérale périphérique 62 de contour sensiblement rectangulaire qui délimite un logement 64 dans lequel est reçu et fixé le support 22, la face inférieure plane 66 du couvercle 24 étant coplanaire avec la face inférieure 48 du support 22.As can be seen in FIG. 8, the cover 24 is essentially constituted by an upper plate 60 perforated by the windows 42 and by a peripheral side skirt 62 of substantially rectangular outline which delimits a housing 64 in which is received and fixed the support 22, the flat lower face 66 of the cover 24 being coplanar with the lower face 48 of the support 22.

Lorsque le connecteur 16 est monté en position sur la face supérieure 14 de la plaque à circuit imprimé 10, les parties incurvées de contact 68 et 68' des branches de raccordement 46, 46' viennent coopérer avec les pistes conductrices de la face supérieure 14 pour assurer le raccordement électrique des lames 26 avec ses pistes et leur convexité tournée vers la face 14 provoque une déformation élastique des branches 46, 46' à l'intérieur du logement 52 pour venir occuper la position illustrée en silhouette sur la figure 8.When the connector 16 is mounted in position on the upper face 14 of the printed circuit board 10, the curved contact parts 68 and 68 'of the connection branches 46, 46' cooperate with the conductive tracks of the upper face 14 for ensuring the electrical connection of the blades 26 with its tracks and their convexity facing the face 14 causes an elastic deformation of the branches 46, 46 ′ inside the housing 52 to come to occupy the position illustrated in silhouette in FIG. 8.

Comme on peut le constater sur la figure 8, les parties incurvées de raccordement 68, 68' sont situées "à l'intérieur" du connecteur 16, c'est-à-dire qu'elles sont situées à l'intérieur du périmètre général du connecteur 16 et, en position de raccordement montée du connecteur 16 sur une plaque 10, elles sont entièrement protégée par la périphérie 62 du couvercle 24.As can be seen in Figure 8, the curved connecting parts 68, 68 'are located "inside" of the connector 16, that is to say they are located inside the general perimeter of the connector 16 and, in the connection position mounted on the connector 16 on a plate 10, they are fully protected by the periphery 62 of the cover 24.

Le connecteur 16 est monté dans un logement 70 du boîtier de protection, et notamment de blindage, 18 qui est délimité par une paroi latérale périphérique 72 qui, en position montée du connecteur 16 dans le boîtier de protection 18, entoure entièrement la partie latérale 62 du corps 20 du connecteur 16.The connector 16 is mounted in a housing 70 of the protective housing, and in particular of the shielding, 18 which is delimited by a peripheral side wall 72 which, in the mounted position of the connector 16 in the protective housing 18, completely surrounds the lateral part 62 body 20 of connector 16.

La face supérieure 74 du boîtier 18 est ainsi ouverte pour permettre l'introduction, verticalement de haut en bas en considérant les figures 1 et 2, du corps 20 du connecteur 16 dans le logement 70 et permettre le passage des parties incurvées de contact 34 des lames de contact 26.The upper face 74 of the housing 18 is thus open to allow the introduction, vertically from top to bottom, considering Figures 1 and 2, of the body 20 of the connector 16 in the housing 70 and allow the passage of the curved contact parts 34 of the contact blades 26.

La face supérieure 74 est sensiblement coplanaire avec la face supérieure 36 du connecteur 16.The upper face 74 is substantially coplanar with the upper face 36 of the connector 16.

Le boîtier 18 délimite également une face inférieure 76 parallèle à sa face supérieure 74 qui est coplanaire avec la face inférieure 48 du connecteur 16 et qui est également ouverte pour permettre le passage des extrémités incurvées de raccordement 68, 68' pour leur venue en contact avec la face supérieure 14 de la plaque à circuit imprimé 10.The housing 18 also defines a lower face 76 parallel to its upper face 74 which is coplanar with the lower face 48 of the connector 16 and which is also open to allow the passage of the curved connection ends 68, 68 ′ for their coming into contact with the upper face 14 of the printed circuit board 10.

Dans le mode de réalisation illustré sur les figures, le boîtier 18 comporte également un fond ou cloison horizontale intermédiaire 78 qui s'étend entre la face supérieure 74 et la face inférieure 76 et qui constitue un plan 80 d'appui pour une partie évidée 80 de la face inférieure 66 du couvercle 24 du connecteur 16 sur lequel elle prend appui par une portion de face inférieure 82.In the embodiment illustrated in the figures, the housing 18 also includes an intermediate horizontal bottom or partition 78 which extends between the upper face 74 and the lower face 76 and which constitutes a support plane 80 for a hollowed out part 80 of the lower face 66 of the cover 24 of the connector 16 on which it bears by a portion of lower face 82.

De ce fait, et comme cela est illustré sur la figure 8, les deux lames de contact 26, 26' appartenant à une paire de lames alignées selon la direction longitudinale parallèle aux faces 36 et 66 sont d'une conception légèrement différente.Therefore, and as illustrated in Figure 8, the two contact blades 26, 26 'belonging to a pair of blades aligned in the longitudinal direction parallel to the faces 36 and 66 are of a slightly different design.

La lame 26 de gauche en considérant la figure 8 est telle que la zone incurvée de raccordement 68 s'étend dans le même plan vertical que la branche de liaison 28 et que la branche de raccordement 30 et elle est située verticalement sensiblement au droit de la partie incurvée de contact 34.The blade 26 on the left considering FIG. 8 is such that the curved connection zone 68 extends in the same vertical plane as the connection branch 28 and that the connection branch 30 and it is located vertically substantially at the right of the curved contact part 34.

En ce qui concerne la lame 26' de droite, sa branche de raccordement 46' est décalée longitudinalement par rapport à ses branches de liaison 28 et de contact 30 de manière que sa partie incurvée de raccordement 68' soit décalée longitudinalement en direction de l'autre lame 26, c'est-à-dire qu'elle se situe sensiblement au droit de la partie intermédiaire du connecteur situé à mi-distance entre les deux parties incurvées de contact 34 dont la position relative est normalisée.As regards the blade 26 'on the right, its connecting branch 46' is offset longitudinally with respect to its connecting branches 28 and contact 30 so that its curved connecting portion 68 'is offset longitudinally in the direction of the another blade 26, that is to say that it is situated substantially in line with the intermediate part of the connector located midway between the two curved contact parts 34 whose relative position is normalized.

Afin de conférer une élasticité suffisante à la branche 46', son coude 50' de raccordement à la branche de liaison 28 est relié à cette dernière par un tronçon ou branche complémentaire de liaison 86 qui s'étend parallèlement à la branche principale de liaison 28, en-dessous de cette dernière, de manière à dégager l'évidement 80 et de manière à assurer le positionnement adjacent des becs 54 d'extrémité des deux lames alignées 26, 26' qui coopèrent avec la surface commune de butée 56 pour définir les positions d'origine des parties de raccordement 68, 68'.In order to impart sufficient elasticity to the branch 46 ', its elbow 50' for connection to the connecting branch 28 is connected to the latter by a complementary connecting section or branch 86 which extends parallel to the main connecting branch 28 , below the latter, so as to clear the recess 80 and so as to ensure the adjacent positioning of the end nozzles 54 of the two aligned blades 26, 26 'which cooperate with the common abutment surface 56 to define the original positions of the connection parts 68, 68 '.

La fixation du connecteur 16 dans le boîtier 18 est assurée par emboîtement élastique grâce à des becs chanfreinés 88 formés dans deux faces latérales opposées de la jupe périphérique 62 du couvercle 24 et grâce à un rebord 90 entre lesquels est reçu un épaulement transversal interne 92 formé en vis-à-vis dans la face interne du logement 70 du boîtier 18.The connector 16 is fixed in the housing 18 by elastic interlocking thanks to chamfered spouts 88 formed in two opposite lateral faces of the peripheral skirt 62 of the cover 24 and thanks to a flange 90 between which an internal transverse shoulder 92 formed is received. facing each other in the internal face of the housing 70 of the housing 18.

Le connecteur 16 monté dans son boîtier 18 constitue ainsi un composant unitaire qui peut être monté directement sur la plaque à circuit imprimé 10 par l'intermédiaire de moyens de fixation (non représentés) appartenant au boîtier 18 et/ou au connecteur 16.The connector 16 mounted in its housing 18 thus constitutes a unitary component which can be mounted directly on the printed circuit board 10 by means of fixing means (not shown) belonging to the housing 18 and / or to the connector 16.

Le boîtier 18 peut aussi, à titre de variante, appartenir à un sous-ensemble qui est lui-même fixé sur la plaque à circuit imprimé 10 ou positionné par rapport à cette dernière.The housing 18 can also, as a variant, belong to a sub-assembly which is itself fixed to the printed circuit board 10 or positioned relative to the latter.

Quel que soit le mode d'assemblage et montage, le raccordement des lames de contact 26 est assuré automatiquement sans opération de brasage, par l'appui élastiquement des zones de raccordement 68 contre les pistes conductrices correspondantes de la face supérieure 14 de la plaque à circuit imprimé 10.Whatever the assembly and mounting method, the contact blades 26 are automatically connected without brazing operation, by elastically pressing the connection zones 68 against the corresponding conductive tracks of the upper face 14 of the plate to printed circuit 10.

Sans sortir du cadre de l'invention, les deux lames alignées d'une paire peuvent être identiques à une lame 26.Without departing from the scope of the invention, the two aligned blades of a pair may be identical to a blade 26.

Sans sortir du cadre de l'invention, le connecteur électrique peut être du type dans lequel l'ensemble des extrémités de raccordement de toutes les lames de contact sont regroupées du même côté du support isolant, le boîtier de protection et de blindage ne comportant alors qu'une seule fente dans sa face inférieure, fente de faible largeur qui assure un meilleur blindage de la carte SIM à mémoire électronique.Without departing from the scope of the invention, the electrical connector can be of the type in which all of the connection ends of all the contact blades are grouped on the same side of the insulating support, the protective and shielding box then only comprising a single slot in its underside, a narrow slot which provides better shielding of the SIM card with electronic memory.
