ABSTRACT:
A card connector, having a card insertion slit in a connector body and a resilient contacting piece for engaging a card inserted in the slit, uses just a single cam block having a card supporting surface for supporting and moving a card inserted into the card insertion slit. A plain cam surface on the single cam block opens and closes the contacting piece for allowing the card to be easily inserted and for moving a contact surface of the contacting piece against the card for rubbing the card to improve the electrical contact when the card is subsequently moved. The single cam block is diagonally movably supported on the connector body for movement along a diagonal movement path. The contacting piece and the contacting piece opening/closing plain cam surface are arranged such that the contacting piece is opened by the downward diagonal movement of the cam block for permitting the card to be inserted with no load, the card is pushed up and the contacting piece is closed by the initial upward diagonal movement of the cam block, and the card is further pushed up while keeping the contacting piece closed in order to obtain sliding contact between the card and the contact surface.
