ABSTRACT:
A card connector for use with an electronic appliance through an IC card having a plurality of recesses extending from its front end toward its rear end in parallel with one another and contact pads each being received in the recess. The card connector includes a connector housing and contact terminals. The connector housing has a pair of guide grooves for supporting and guiding both side edges of a card being inserted into the card connector and an insertion space in the housing for the inserted card. The contact terminals made of a springy and electrically conductive material are arranged in the connector housing and each have a contact portion adapted to contact with a contact pad of the card normally inserted in the card connector. According to the invention, the card connector comprises support protrusions each provided at a location below at least the contact portion of the contact terminal to limit the downward displacement of the contact portion of the contact terminal when the card has been normally inserted in the card connector, thereby ensuring a contact force more than a predetermined value between the contact portions of the contact terminals and the contact pads of the card.
