Abstract: In an integrated circuit (IC) card connector, an opening is formed between a base and a cover; and a rotary shaft of a lever member is rotatably retained, and includes a pressing portion and an inclined portion, both of which are formed at the lower face of the lever member through the rotary shaft. A plurality of terminals are affixed to the base in the manner of a cantilever. Contact portions of each of the terminals are such as to protrude into the opening, by an amount which is restricted by a pressurization restricting member which pressurizes them. The resilient member, having a taper portion and a flat portion, is integrally molded with the base. The taper portion is extended obliquely from the inside bottom surface of the opening towards the back side of the IC card connector. The flat portion protrudes with respect to the inside bottom surface of the opening, and is positioned above the contact portions.

Abstract: An IC card connector having a detecting switch for detecting correct installation of the IC card is provided.The actuator of the detecting switch is provided with a projected tongue piece obliquely protruding toward the card insertion section, in a manner such that the projected tongue piece is adapted to be driven in the IC card's thickness direction by the IC card just before the completion of its insertion. Therefore, an elastic force of the actuator (this force will exert on the IC card which has been inserted in its loading position) may be made generally orthogonal to the IC card's discharge direction. In this way, with the passing of time even if there occurs a deterioration in the clamping force of the connector for clamping the IC card, the IC card will not be pushed by the detecting switch in its discharge direction. Thus it is possible to avoid a position deviation of the IC card when in its inserted position.

Abstract: An IC card connector wherein an elastic piece is provided on a base of a housing, extending cantilevered in the direction of IC card insertion and using the free end portion thereof as a click projection. The IC card drives the click projection immediately before complete insertion to produce a feel of a click, thus completing the insertion of the IC card, so that the user inserting the IC card into a card slot of the housing will be able to definitely know proper card insertion by the feel of click and vibration.
