Patent attributes
A socket for an electrical part includes a socket body formed with an accommodation portion in which an electrical part having spherical terminals is accommodated and contact pins arranged to the socket body to be contacted to and separated from the terminals such as solder balls, respectively, and a movable member for elastically deforming the contact pins in a horizontal direction. Each of the contact pins has one elastic piece in form of plate having conductivity and elasticity so as to be elastically deformable along a plate surface direction by the movement of the movable member. The contact pin has a contact portion in form of plate formed at an upper portion of the elastic piece, and the contact portion has a side edge portion which is contacted to or separated from a side surface of the spherical terminal.
