  • Patent number: 11050178
    Abstract: Embodiments implement rotation stoppage for a contact pin at a lower cost, in which the contact pin is disposed in a socket main body to establish electrical conduction between an IC package and a wiring board. The contact pin has a barrel, an upper contact member, a lower contact member, and a coil spring. The barrel has a flange that has rotation stoppers protruding in the horizontal direction. When the contact pin is disposed in a socket main body, the rotation stoppers of the flange are brought into contact with the socket main body, whereby the barrel is restrained from rotating relative to the socket main body.
