Abstract:
An integrated circuit (IC) socket for electrically connecting terminals formed on a bottom surface of a surface-mount IC package to respective ones of predetermined electrodes of a printed circuit board, comprising:a body member made of an insulating material, the body member having a top surface and a bottom surface thereof, wherein a plurality of-main through-holes are formed between the top surface and the bottom surface so that the main through-holes correspond to respective ones of the terminals of the surface-mount IC package;a pair of an upper contact member and a lower contact member which are accommodated in each of the main through-holes and are electrically connected to each other so as to electrically connect the terminals of the surface-mount IC package to respective ones of the predetermined electrodes of the printed circuit board, wherein at least the upper contact member is slideably accommodated and biased to protrude from the top surface of the body member; anda circuit board member which enables input/output of electrical signals between the IC socket and an external system fixed to the top surface of the body member, the circuit board member having a plurality of upper through-holes corresponding to respective ones of the main through-holes, and further having a plurality of conductors which are electrically connected to the main through holes, wherein the upper contact member protrudes through a corresponding one of the upper through-holes by a predetermined length.
