  • Patent number: 8801450
    Abstract: An IC socket includes a socket body, a contact pin that contacts a terminal of an IC package, and a latch that presses the IC package from an upper side thereof. An elastic piece of the contact pin is extended along substantially horizontal direction. The latch is formed with a can portion. When the latch is rotated in an opening direction thereof, the elastic piece is pressed by the cam portion so as to be elastically deformed downward so that the contact portion is displaced to be separated downward from a contacting position to the terminal of the IC package. When the latch is rotated in a closing direction thereof, a pressing force of the cam portion applied to the elastic piece is released so as to displace the cam portion upward by the elastic force of the elastic piece to thereby contact the terminal of the IC package.
