Patent ID: 7004762

Claim:
A socket for an electrical part which is mounted to a circuit board and in which an electrical part is mounted so as to be electrically connected to the circuit board, said socket comprising: an upper plate for guiding and accommodating the electrical part; a contact sheet disposed on an upper surface of the circuit board; a land sheet disposed between the contact sheet and the electrical part; and a lower plate disposed between the circuit board and the contact sheet for clamping end portions of the contact sheet and end portions of the land sheet between the upper and lower plates, said upper plate being provided with a side wall section extending downward for positioning the end portions of the contact sheet and the end portions of the land sheet, said contact sheet including an elastic body in form of a plate having first and second surfaces and having elasticity and an insulating property and a conductive portion embedded in the elastic body, said conductive portion having end portions exposed to both the first and second surfaces of the plate of the elastic body so as to be electrically connected to the land sheet, said land sheet being composed of an insulating sheet having first and second surfaces having first and second electrode portions formed thereon respectively to be electrically conductive to each other, one of said first and second electrode portions being formed on one of the first and second surfaces of the land sheet to be contacted and electrically connected to a terminal of the electrical part and the other of the first and second electrode portions being formed on the other of the first and second surfaces of the land sheet to be contacted and electrically connected to the conductive portion of the contact sheet so as to electrically connect the electrical part to the circuit board.
