Abstract:
A PC card connector equipped with an ejecting mechanism, comprising:a connector frame having a header section having an array of plural terminal pins, and a pair of opposed arm sections extending from both side ends of the header section and guiding the side edge of a PC card along an insertion/withdrawal direction of the PC card;an ejecting plate having engaging sections for engaging with the PC card and guided along an insertion/withdrawal direction of the PC card;a link member having a coupling section coupled to the ejecting plate so as to be swingable, a support section swingably supported at the header section in spaced-apart position from the coupling section, and projection extending from the support section toward an opposite side of the coupling section and projecting into the side of the connector frame;a push rod having an inner end section disposed adjacent to the header section side of the connector frame and an outer end section spaced apart from the header section and adapted to receive an urging force, and being moved from an outwardly extended position spaced apart from the header section to an inwardly pushed-in position near the header section;urging means for urging the push rod toward the outwardly extended position; andan operation device which moves the ejecting plate in the PC card withdrawal direction through the link member when the push rod is moved from the outwardly extended position to the pushed-in position by the urging force from the outer end section, and latches the push rod to a retained position more on an outer side than the pushed-in position when the urging force is released with the push rod set in the pushed-in position, and further, unlatches the push rod so as to be returned to the outwardly extended position when the push rod set in the retained position receives the urging force through the outer end section;the operation device including a movable actuator member which is disposed at the inner end section of the push rod so as to be abutted against the projection of the link member and moves along a movement direction of the push rod together with the inner end section while linearly moving along a direction substantially orthogonal to the movement direction of the push rod, and a cam for operating the actuator member,the cam having a drive section for moving the actuator member so that the actuator member is supported by the inner end section in a movement direction of the push rod on at least two positions and abuts against the projection of the link member when the push rod is moved from the extended position to the pushed-in position, a latching section for latching the actuator member to a position incapable of abutting against the projection of the link member and for latching the push rod to the retained position while preventing the push rod from being returned to the extended position when the push rod is situated in the pushed-in position and the urging force is released, and a return section for unlatching the actuator member and guiding it toward the drive section while returning the push rod to the extended position when the push rod in the retained position receives the urging force through the outer end section.
