Abstract:
A female connector for an IC card, said connector being incorporated into the IC card and connected to a plurality of contact pins provided in an apparatus, said connector comprising:a housing formed of an insulating material and provided with a plurality of contact pin receiving holes for receiving the plurality of contact pins; andterminal pins arranged in the contact pin receiving holes and electrically connected to one contact pin inserted in the contact pin receiving holes;each terminal pin comprising a plate-like base part made of metal, and a pair of contact parts formed by bending a part of the base part to be located at positions opposing each other in each contact pin receiving hole and contacting each contact pin;one end of the base part being electrically coupled to a circuit board provided in the housing, the other end of the base part being a free end, and the pair of contact parts being formed between both ends of the base part;wherein the housing is provided with a pair of positioning projections corresponding to the contact pin receiving holes, each positioning projection forming a space equivalent to a thickness of the free end of the base part between each positioning projection and an inner wall of each contact pin receiving hole, and a part of the inner wall of one contact pin receiving hole so as to guide each contact pin in the direction of insertion and removal while sliding each contact pin;the pair of positioning projections are provided to form inner wall surfaces opposing in one receiving hole; andwherein widthwise both ends of the free end of the base part are inserted and fixed to the pair of spaces formed by the pair of positioning projections for positioning each the terminal pin in the direction of the thickness of the base part by each positioning projection.
