Patent ID: 8272882

Claim:
A semiconductor device socket comprising: a socket body adapted to be disposed on a wiring board having an electrode surface on which an electrode group is formed, the socket body having a semiconductor device accommodating portion in which a semiconductor device is housed detachably and attachably; a contact terminal being disposed on said socket body, said contact terminal having a pair of movable side contact pieces, a fixed side terminal, and a fixing portion, said contact terminal for connecting a terminal of the semiconductor device electrically to the electrode surface of the wiring board, the pair of movable side contact pieces being elastic and pinching the terminal of the semiconductor device, the fixed side terminal having a plurality of curved portions formed to be continuous with each of the contact pieces and elastically displaceable in a direction orthogonal to the electrode surface of the wiring board and a contact point which comes into contact with the electrode surface of the wiring board, the fixing portion for connecting proximal end portions of the pair of movable side contact pieces of said contact terminal to another end of the fixed side terminal; a slider member having a pressing portion which moves at least one movable side contact piece of the paired movable side contact pieces of said contact terminal so as to cause the one movable side contact piece to approach or to separate from the other movable side contact piece each other; and a slider driving mechanism which causes the pressing portion of said slider member operate so that the pair of movable side contact pieces of said contact terminal are brought into contact with or separated from the terminal of the semiconductor device, wherein an end of the curved portions is directly connected to a side edge of the fixing portion, and wherein said curved portions comprise a first curved portion extending upward from the contact point coming into contact with the electrode surface of the wiring board, and a second curved portion having a first end which is continuous with one end of the first curved portion and which, adjacent the first end, extends downward and the second curved portion also extends upward, after extending downward, toward a second end of the second curved portion and the second end of the second curved portion is the end of the curved portions directly connected to a side edge of the fixing portion.
