Abstract:
An electronic card connector comprising:an insulative header retaining a plurality of contact elements therein, and two guide arms extending from opposite ends of the header defining a card receiving space therebetween adapted to receive an electronic card, a card release mechanism operable by a card release bar for releasing the electronic card from the connector;the card release bar being movably mounted to one of the guide arms for driving the card release mechanism to release the electronic card, a foldable button comprising a fixed block fixed to a free end of the card release bar, and a movable block pivotally mounted to the fixed block to be pivotally movable between a stowed position in which the movable block is substantially normal to the fixed block, and a working position in which the movable block is substantially aligned with the fixed block thereby allowing a user to apply an axial force to push the card release bar, and biasing means for automatically biasing the movable block toward the stowed position;two recesses defined in top and bottom faces of the fixed block and forming a recessed section of the fixed block;two spaced tabs formed on the movable block for being slidably received in the corresponding recesses of the fixed block; andtwo arcuate slots having a common center and defined in the recessed section of the fixed block, two pins being mounted to the tabs of the movable block and respectively movably received in the arcuate slots for guiding the pivotal movement of the movable block about the center between the stowed position and the working position; whereinsaid biasing means is a helical spring, and a slot is defined in the fixed block parallel to the top and bottom faces thereof for accommodating the helical spring, the helical spring having a first end attached to the fixed block and a second end fixed to one of said two pins of the movable block.
