Abstract:
1. A card edge connector comprising: an insulative housing extending along a longitudinal direction and defining a card-receiving slot for receiving a card; a plurality of contacts with contacting portions extending into the card-receiving slot from top and bottom sides thereof; and a pair of locking arms attached to lateral sides of the insulative housing, each locking arm comprising a retaining portion fixed to the insulative housing and a resilient arm extending forwardly from the retaining portion, the resilient arm being deformable outwardly so as to lock or unlock with the card, the resilient arm comprising an engaging portion extending inwardly and a hook at a front of the engaging portion, the engaging portion comprising a downwardly inclined surface for guiding installation of the card and a bottom surface for pressing against a top surface of the card when the card is installed in position; wherein the hook comprises a top edge, a bottom edge and a locking surface between the top edge and the bottom edge, the top edge protruding upwardly beyond the engaging portion so that when the card is not so inserted along a card-insertion direction to a predetermined position, even if the card is downwardly pressed, the top edge of the hook resists against the card so as to prevent the card from further downward movement.
