Description

  The present invention relates to an IC card connector for electrically connecting a mounted IC card and a wiring board.

  An IC card connector on which an IC card such as a SIM card is mounted is arranged on a wiring board in an electronic device as disclosed in Patent Document 1, for example. The IC card connector includes a contact terminal group for electrically connecting the IC card and the wiring board in the card housing portion. Each contact terminal constituting such a contact terminal group is made of a thin metal material, and supported by a resin base member in the connector at a fixed terminal portion described later. One end of the fixed terminal portion of each contact terminal protrudes outward from the rear wall forming the card insertion slot of the card accommodation section or the card accommodation section facing the card insertion slot.

  Each contact terminal has a movable piece portion that has a contact portion that comes into contact with a contact pad of an IC card and is elastically displaceable, and a fixed terminal portion that is connected to the movable piece portion and fixed to a base member that forms a card housing portion. It is comprised including. As described above, one end of the fixed terminal portion protruding outward is fixed by soldering to the conductive layer of the wiring board, for example.

  When the IC card connector is mounted inside a relatively miniaturized electronic device such as a mobile phone, it is desired to further reduce the height of the contact terminal. In some cases, it is desired that the thickness of the bottom portion becomes thinner, for example, that the thickness of the bottom portion of the base member be 1 mm or less.

  Further, in the case of the thin base member as described above, in order to prevent the base member from being easily bent, for example, as shown in Patent Document 2, a base member extending in the longitudinal direction (In Patent Document 2, an insulator is used. Is proposed so that the soldered part of the terminal part of each contact fixed to the base member protrudes from both side parts along the longitudinal direction of the base member. Has been. Thereby, bending of a base member will be prevented.

  FIG. 1 shows an appearance of an example of an IC card connector according to the present invention.

  The IC card connector shown in FIG. 1 is, for example, a connection between an electrode portion of a memory card SC as an IC card that is detachably accommodated in the card accommodating portion 10A and a wiring board disposed inside a predetermined electronic device. The terminal portion is electrically connected. The IC card connector is arranged inside an electronic device such as a mobile phone, a telephone, a PDA, or a camera. The thin-plate memory card SC is, for example, a SIM card, and six electrode pads are formed on one surface portion corresponding to the arrangement of contact terminals described later.

  The IC card connector includes a base member 10 on which a plurality of contact terminals that are electrically connected to the memory card SC to be accommodated are arranged.

  The storage chamber of the memory card SC is formed by the inner peripheral portion of the housing (not shown) of the electronic device in which the IC card connector is arranged and the base member 10. That is, the base member 10 is covered with the inner peripheral portion of the casing. In addition, you may form a storage chamber not only by the inner peripheral part of a housing | casing but by the cover member and the base member 10 which cover the base member 10. FIG.

  As shown in FIG. 1, an opening (hereinafter also referred to as a card slot) 10S through which a memory card SC that is attached and detached along the direction indicated by the arrow passes is formed at one end of the card accommodating portion 10A. ing. Further, a notch 10K is formed at the other end of the card accommodating portion 10A so as to face the opening 10S.

  In the center of the bottom 10B of the base member 10, two rectangular openings 10a and 10b arranged at a predetermined interval are formed in three rows. The openings 10a and 10b are formed in an elongated shape substantially parallel to the side walls 10RW and 10LW. The openings 10a and 10b in the same row are formed on a common straight line. As shown in FIG. 1, the openings 10a and 10b in the same row are partitioned by a partition wall formed in the middle thereof. Further, the openings 10a and 10b in adjacent rows are partitioned by a partition wall.

  In the base member 10 formed of resin, contact terminals 14ai and 16ai (i = 1 to 3) are arranged by insert molding corresponding to the openings 10a and 10b described above. The contact terminals 14ai and 16ai are in contact with the electrode pads of the memory card SC to be mounted to electrically connect the memory card SC and the wiring board PB.

  Each contact terminal 14ai is made of a sheet metal material by pressing as shown in an enlarged manner in FIG. The contact terminal 14ai includes a movable piece portion 14B having a contact portion 14bc that is in contact with and electrically connected to the electrode pad of the memory card SC, and a soldered terminal portion 14sf fixed by soldering to the conductive layer of the wiring board PB.

  The elastically displaceable movable piece portion 14B and the soldered terminal portion 14sf protrude from the bottom portion of the base member 10, respectively. The movable piece support portion 14D, the connecting portion 14C, and a part of the rear end portion 14F are each cast into the bottom portion of the base member 10. Further, the soldered terminal portion 14sf protrudes outward through the notch 10K so as to be in the opposite direction to the card slot side. Thereby, since solder does not adhere to the periphery of the card slot in the base member 10, there is no possibility that trouble may occur due to solder when the memory card SC is attached or detached.

  The movable piece portion 14B has a curved contact portion 14bc at the tip. The contact part 14bc is formed corresponding to the arrangement of the electrode pads of the inserted memory card SC. The movable piece support portion 14 </ b> D is formed so as to extend substantially parallel to the end surface of the bottom portion forming a part of the card slot in the base member 10.

As shown in the enlarged view of FIG. 2, the corresponding protrusion 14d of the adjacent contact terminal 14ai is inserted into the recess 14r with a predetermined gap Ga. The gap Ga is set according to the plate thickness of the contact terminal 14ai.

  Thereby, between the adjacent contact terminals 14ai, the overlapping portion formed by the convex portion 14d and the concave portion 14r has the same effect as the case where the reinforcing metal fitting is cast into the base member 10, so that the base member 10 which is insert-molded. The bending rigidity of the end of the bottom forming part of the card slot is increased. Therefore, the base member 10 is restrained from bending in the Z-coordinate axis direction due to thermal stress in the arrangement direction of the contact terminals 14ai, that is, the direction along the X-coordinate axis of the orthogonal coordinates in FIG. 1 is set in parallel to the side walls 10LW and 10RW of the base member 10.

  In FIG. 3, the distance La from the end surface of the movable piece support portion 14D to the bent portion of the rear end portion 14F is a length La ′ along the Y coordinate axis of the bottom portion 10B of the base member 10, as shown in FIG. Are set equal. The connecting portion 14C extends along the Y coordinate axis direction described above. At that time, a connecting end portion is formed by the connecting portion 14C and the rear end portion 14F.

The movable piece support portion, the connecting portion 16C, and a part of the rear end portion 16F are each cast into the inside of the bottom portion of the base member 10.

  FIG. 4 shows another example of contact terminals used in an example of an IC card connector according to the present invention.

  In the example shown in FIG. 3, adjacent contact terminals 14ai have the same shape, and corresponding concave portions 14d of adjacent contact terminals 14ai are inserted into the concave portions 14r with a predetermined gap Ga. It is said.

  Thereby, between the adjacent contact terminals 20ai and 18ai, the overlapping portion formed by a pair of convex portions 20d and concave portions 18r, which will be described later, has the same effect as the case where the reinforcing metal fitting is cast into the base member 10. Therefore, the bending rigidity of the end portion of the bottom portion that forms a part of the card slot in the insert-molded base member 10 is increased. Accordingly, the base member 10 is restrained from bending in the Z-coordinate axis direction due to thermal stress in the arrangement direction of the contact terminals 18ai, that is, the direction along the X-coordinate axis of the orthogonal coordinates in FIG.

  In FIG. 4, the connecting portion 18C1 extends along the Y coordinate axis direction shown in FIG. Thereby, the base member 10 is restrained from bending in the Z coordinate axis direction due to thermal stress in the direction along the Y coordinate axis of the orthogonal coordinates in FIG.

  A convex portion 20d is also formed at a portion where the end of the movable piece portion 20C1 in the movable piece support portion 20D is connected. The pair of convex portions 20d formed to face each other are inserted into the concave portions 18r of the contact terminals 18ai adjacent to both sides thereof with a predetermined gap. Therefore, also in such an example, the bending rigidity mentioned above is improved, and the bending in the Z coordinate axis direction due to thermal stress is suppressed.

  FIG. 5 shows still another example of contact terminals used in an example of an IC card connector according to the present invention.

  In the example shown in FIG. 3, adjacent contact terminals 14ai have the same shape as each other, and the convex portion 14d and the concave portion 14r are formed on the same plane as the flat surface of the movable piece support portion 14D.

Further, the soldered terminal portion 24sf protrudes to the outside through the notch portion 10K so as to be opposite to the card slot side. The elastically displaceable movable piece 24B has a curved contact portion 24bc at its tip.

  The movable piece support 24D is formed so as to extend substantially in parallel to the end surface of the bottom forming part of the card slot in the base member 10. The movable piece support portion 24D has a bent surface formed by bending the end portion of the flat surface to which the end portion of the movable piece portion 24B is connected in the Z coordinate axis direction. In addition, a concave portion (notch portion) 24r is formed on the side of the bent surface where the end of the movable piece portion 24B of the movable piece support portion 24D is connected. Further, a convex portion 24d is formed on the side where the one end portion of the connecting portion 24C is connected to the bent surface so as to face the concave portion 24r. Corresponding convex portions 24d in adjacent contact terminals 24ai are inserted into the concave portions 24r with a predetermined gap. The gap is set according to the plate thickness of the contact terminal 24ai.

  Thereby, like the above-mentioned example, the bending rigidity of the edge part of the bottom part which forms a part of card slot in the base member 10 is improved. Further, the length of the base member 10 in the Y coordinate axis direction can be reduced as compared with the example shown in FIG.

The convex portion 28P is inserted into the concave portion 30r of the contact terminal 30ai adjacent in another row with a predetermined gap.

  As a result, between the adjacent contact terminals 28ai and 30ai, the overlapping portion formed by the convex portion 28P and the concave portion 30r has the same effect as the case where the reinforcing metal fitting is cast into the base member 10, so that the insert molded base The bending rigidity of the bottom portion forming the vicinity of the notch portion 10K in the member 10 is also increased. At the same time, in the direction along the Y coordinate axis shown in FIG. 1, the base member 10 is restrained from bending in the Z coordinate axis direction due to thermal stress by the connecting portion 28C.
