Abstract:
1. A semiconductor device socket for electrically connecting between a semiconductor device and a printed-wiring board, the semiconductor device socket comprising: a socket body having contacts to be electrically connected with the semiconductor device; and a connection mechanism provided between the socket body and the printed-wiring board, including connection members for electrically connecting between the contacts and pads of the printed-wiring board and an alignment plate having a cylindrical through-hole, said through-hole having one of the connection members; wherein each connection member provided in the through-hole has a first spring portion having a first free end, a circular support portion having an outer diameter greater than an inner diameter of the through-hole, a positioning portion having an outer diameter smaller than the inner diameter of the through-hole and a second spring poriton and having a second free end, the first and second spring portions are coil springs, the second spring portion has an outer diameter smaller than the inner diameter of the through-hole so as to vertically move within the through-hole, each first free end of each first spring portion electrically connects with one of the corresponding contacts of the socket body and each second free end of each second spring portion electrically connects with the corresponding pad of the printed-wiring board, and the circular support portion abuts against the outer surface of the alignment plate on opposite sides when the positioning portion and the second spring portion of the connection member are inserted in the through-hole, thereby the connection member being retained on the alignment plate.
