Abstract: A card connector device includes a case having a receptacle space for receiving a card having a specific width and an opening for inserting the card therethrough; a connector disposed at an end portion of the receptacle space in a direction that the card is inserted for connecting the card; a shutter member arranged adjacent to the opening to be pushed with a front end of the card when the card is inserted, so that the shutter member rotates from a closed position to an open position around an axial line extending along a width direction of the card; and a stopper member for preventing the shutter member from rotating toward the open position when a card with a width smaller than the specific width is inserted.

Abstract: A card connector device includes a case having a receptacle space for receiving a card and an opening for inserting the card therethrough; a connector disposed at an end portion of the receptacle space in a direction that the card is inserted for connecting the card; a shutter member arranged to be rotatable around a shaft along a width direction of the opening for opening and closing the opening; an urging member for urging the shutter member toward a stopper defining a closed position or from the closed position to an open position; and a guide member for guiding a card having a width smaller than that of the opening, so that the card with a small width can be inserted into the receptacle space at a specific position in addition to a card having a width same as that of the opening.

Abstract: An electrical card connector comprises an ejector (4), a spring member (10) pushing the ejector backward and an ejecting bar (5) advanced by a force from the ejector, applying the force to a transmission mechanism. The ejector comprises an engaging member (12) guided by a cam member (7) provided in housing. The engaging member is engaged with and released from engaging bar. The cam member is provided as a cam groove (17) forming a circulation rout. The cam groove is formed so that the engaging member engages with the ejecting bar only when the ejector advances for card ejection and the engaging member (12) is released from the ejecting bar and the ejector (4) is moved backward under a pressure from the spring member (10) at other times than the card ejection.

Abstract: An ejector lever (9) has a first push portion (10) and a second push portion (12) spaced from the fulcrum stud (8) further than the first push portion (10) in order to push a slider member (13). The second push portion (12) is provided on a cantilever spring (11) so as to provide the slider member (13) with spring forces when the first push portion (10) releases the connection between the PC card (1) and the connector section (5).

Abstract: A circuit board electrical connector which includes a first connector (10) connectable to a first external member (Q) and a second connector (30) connectable to the first connector at one end and a second external member at the other end opposite to the one end. The first connector includes an insulation block (11) with a connection recess (12) having an opening on a front side thereof; a plurality of first contact elements (20, 21) disposed within the insulation block such that contact portions are exposed in the connection recess.

Abstract: A low connection force electrical connector system includes an elongated housing (1); a connection recess (2) extending in a longitudinal direction of said elongated housing and having a regulation face (8) and a guide face (7) in a plane parallel to a bottom face of said elongated housing; at least one upper and one lower channel (3, 4) formed on upper and lower inside walls of said connection recess, respectively; at least one upper and one lower contact element (10, 11) fitted in said upper and lower channel, respectively; and a circuit board (P) having an insertion slope (P1) at a lower front edge thereof.
