Abstract

A socket for mounting an electrical part such as an IC chip 60 in a freely detachable manner in which the electrical part 60 has a plurality of connective terminal parts of a prescribed pitch, has socket terminals 50 fixed in the socket 10 and a plurality of electroconductive parts 34 positioned on an insulating substrate 32. Each of the electroconductive parts 34 has first and second contact areas (34a, 34b) areas with the first contact area 34a having the same pitch as the pitch between the connective terminal parts BP. The insulating substrate 32 is held by a spring biased support member to provide for reliable contacting with the electrical part 60. The first contact area 34a of the electroconductive parts 34 provides electrical connection with one of the connective terminal parts BP of the electrical part 60 and the second contact part 34b provides electrical connection with one of the socket terminals 50 thereby providing reliable electrical connections between the electrical part 60 and the socket. This design provides for electrical connection for electrical parts without external lead terminals.
