Patent ID: 6902424

Claim:
A socket for an electrical part comprising: a socket body on which is formed a mounting portion for mounting an electrical part; contact pins disposed on said socket body and capable of connecting with connection terminals of said electrical part mounted on said mounting portion; at least one opening/closing member provided on said socket body so as to enable it to be opened and closed; and at least one heat sink attached to said at least one opening/closing member capable of moving between a contact position in which said heat sink contacts said electrical part and a withdrawal position in which said heat sink separates from said electrical part so that said electrical part can be inserted into or removed from said socket body; wherein said heat sink includes a contacting section which contacts with said electrical part and receives the heat generated from said electrical part when said heat sink is in the contact position, and a radiating section integral with said contacting section and which transmits the heat conducted to said contacting section into the open air, and wherein the thermal conductivity of said contacting section is higher than the thermal conductivity of said radiating section.
