Abstract:
A zero insertion force electric connector comprising a plurality of terminals, a base, a driving rod and a movable plate, each terminal is punched and bent by a metal piece and including a head at an upper portion thereof and a leg post at a lower portion thereof; the head has two upright clamping pieces; an upward inclined elastic buckle is installed between said clamping pieces; a protrusion is formed at an inner side of an upper section of each clamping piece at a selective position; a slit is formed at a center of the head, and an inclined opening is formed at an upper end of the slit; the two clamping pieces are formed as an elastic cambered structure bending in a front direction and a rear direction; the apexes of the bending are formed as a three fulcrum structure including an upper fulcrum, a middle fulcrum and a lower fulcrum; the base has a surface being formed with a plurality of penetrating stepped rectangular slots; a selected lateral wall at each slot has a buckling groove at the center of a lower section thereof; a vertical receiving groove is formed at a center of an upper lateral wall of a selective slot; an inserting hole is formed at another lateral wall of a selective groove, which inserting hole extends to the top of the base; whereby, each terminal is inserted into the slot from an upper side of the base so that the elastic buckle resists against an upper end of the buckling groove at one lateral wall to prevent its release; while the three fulcrum structure, including said upper fulcrum, said middle fulcrum and said lower fulcrum, elastically resist against a pair of lateral walls of the slot to retain therein steadily.
