Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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. .
  • connection terminals may be insufficient.
  • the object of the invention is to propose a new design of an electrical connector of the type mentioned above which makes it possible to remedy these drawbacks.
  • connection end section of each contact blade is elastically deformable and has a connection part which projects below the lower bearing face of the body.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the upper face 74 is substantially coplanar with the upper face 36 of the connector 16.
  • 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.
  • 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.
  • 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.
  • 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.
  • connection branch 46 ' 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 '.
  • 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 '.
  • 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.
  • 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.
  • 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.
  • 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.
  • the two aligned blades of a pair may be identical to a blade 26.
  • 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.
