ABSTRACT:
A test socket, adapted for connecting the semiconductor package and a printed circuit board comprises a base and a plurality of contacts received in the base. The base has a retaining board defining a plurality of first receiving holes and a positioning board defining a plurality of second receiving holes. The contacts has a contacting portion, an elastic portion and a retaining portion, the elastic portion is disposed between the retaining board and the positioning board and protruding rightward, and the contacting portion extends beyond the elastic portion and defines a acute angle with a horizontal line in a right hand before contacting with the semiconductor package to prevent the contacting portion from scratching with the left inner sidewall of the second receiving hole when pushed downward by the semiconductor package and rotating leftward.
