A connector for IC cards comprising a housing with a plurality of connecting terminals attached thereto, shielding plates disposed on a peripheral surface of the housing, and a circuit board to which the housing and the shielding plates are mounted, wherein the shielding plates are disposed respectively on both an upper surface side and a lower surface side of the housing. Each of the shielding plates are formed with grounding portions and are mounted to the circuit such that the grounding portions are in a superposed arrangement.

Connector for IC card, having shielding plates

An IC card connector grounding structure has an IC card connector having a housing made of an insulating material, in which a plurality of pin terminals are held, and a shield cover mounted on the upper surface of the housing; and a circuit board having a ground circuit pattern, for mounting the IC card connector. The shield cover is grounded in contact with the circuit pattern.

IC card connector grounding structure

A connector for IC card, comprising a housing with plural connecting terminals attached thereto, a shielding plate disposed on the housing, and a circuit board on which the housing and the shielding plate are mounted, wherein the shielding plate is formed with a grounding portion, an end of the grounding portion being extended and bent to form a bent portion as a swivel-stop portion for the nut.

A push rod 4 is held on an outside surface of one side of frame 3 guiding draw and insert of the IC card 1 so that the push rod 4 can reciprocally move, and this push rod 4 is always pressed to the drawn direction of the IC card 1 by a coil spring 10. A transfer pin 12 is rotatably supported by a hole 4c of the push rod 4, and this transfer pin 12 is pressed toward the outside surface of the frame 3 by a flat spring 13. A heart-shaped cam groove 14 having a plurality of cam surfaces A to E is engraved, and an operating section 12a formed at an end of the transfer pin 12 is engaged with this cam groove 14. In addition, a drive plate 15 is held on the outside surface of the frame 3 so that the drive plate 15 can reciprocate along the draw and insert directions of the IC card 1, and a receiving section 15a of this drive plate 15 is inserted into the long groove 3c continuing to the cam surface D of the cam groove 14.

Connector device for IC card

In a PC card connector, first and second support shafts are mounted upright on a pin housing, and each provided with a pair of fall-preventive sections at the leading end thereof. A first turn arm is provided with a circular hole, a protrusion, a tongue, a concave section on the rim of the circular hole, and a pair of cutouts that cross the concave section, and the circular hole is fitted on the first support shaft through the cutouts so that the first turn arm can move pivotally. A second turn arm is formed similarly to the first turn arm, and a circular hole thereof is fitted on the second support shaft so that the second turn arm can move pivotally. A drive lever is provided with a circular hole, an engaging section, a coupling hole, a thin concave section formed on the rim of the circular hole, and a pair of cutouts that cross the concave section. The circular hole is fitted on the first support shaft through the cutouts so that the drive lever can move pivotally, and the drive lever and the first turn arm are prevented from falling off by the fall-preventive sections of the first support shaft. The tongues of the turn arms are engaged with the coupling hole of the drive lever, and the engaging section is engaged with a push-rod.

PC card connector

A pin contact of a connector and a method of fabricating the pin contact which enables a substantial decrease of manufacturing cost, and smooth installation of the pin connector without a change in the pitch of arrangement at the time of press-fitting into a pin housing. A flat metal sheet undergoes blanking and pressing to form a narrow piece including a strip portion of decreased area of a fracture. Then an approximately L-shaped connecting portion is bent at right angles to raise the narrow piece sideways. Thereafter the strip portion of the narrow piece is pressed along the direction of rising, to thereby form an approximately cylindrical contact section. A raised piece at the rear of the contact section is provided with a locking section which faces approximately at right angles with the direction of arrangement.
