ABSTRACT:
A edge connector socket for printed circuit boards comprises an elongate insulative housing having a channeled receiving space extending between respective end portions thereof, and a plurality of conductive contact members disposed on corresponding slots formed perpendicularly along the receiving space. Each end portion has a vertical post with a protruding pin on a first side of the housing and an inclined ramp for guiding the insertion of a daughterboard on a second side of the housing. Each contact member has a resilient spring appendage and a fulcrum appendage formed spacedly thereon so as to define a receiving space for an inserted edge portion of a daughterboard. The spring appendages deflect upon the insertion of a daughterboard and apply a torque thereon so as to rotate the board about a pivot axis defined by the fulcrum appendages in contact with an opposing side thereon. The board is rotated towards the vertical posts upon release so as to engage the pins thereon with cooperating apertures on the board to secure the board in a functional position on the socket.
