Abstract: In a socket for an electrical part, an IC package is received in a socket body. A contact pin is provided for the socket body. The contact pin is formed with a movable contact piece having a movable side contact portion. The movable side contact portion is contacted to a terminal of the IC package and separated from the terminal. In the socket, in a state that the IC package is not received in the socket body, a bent portion is formed on a stationary side contact portion such as a mount portion of the stationary contact piece. The movable contact side portion is seated on the stationary side contact portion so that the movable side contact portion is adapted to be slid on the bent portion, thereby making longer a wiped width of the movable side contact portion.

Abstract: A socket for electric parts is equipped with a socket body having a mounting face on which an electric part is mounted; contact pins fixed on the socket body, each having a contact portion, a trigger portion, and a spring portion; and a cover mounted on the socket body, free to move up and down. The end edge of the contact portion contacts a corresponding lead of the electric part and is configured to incline with respect to the end edge of the lead. The trigger portion and the spring portion are configured to project toward the center of the socket body. The width of the spring portion projecting toward the center of the socket body is such as to increase progressively in going to the base portion of the contact pin. In this way, a high pressure of contact between the lead and the contact pin and a sufficient wiping action are ensured, and a socket for electric parts capable of continued high performance over a long period of time is provided.
