Abstract:
A socket assembly comprising:a plurality of contact pins arranged in parallel on a base plate for loading an electrical component thereon and each having a base arm which is secured to the base plate, an external terminal which is connected to the base arm and extends toward an outside of the base plate, a springy arm which is connected to the base arm and extends toward an upper side of the electrical component so as to form a contact portion which can come into contact with a terminal formed on the upper side of the electrical component, and an engagement portion which is formed on the springy arm and being extended inwardly therefrom; an actuation shaft member extending along the direction of arrangement of the contact pins and having a plurality of engagement projections formed along a circumferential surface thereof and being extended outwardly therefrom for engagement with the engagement portion of each of the contact pins; and a spring member for urging the actuation shaft member for rotation in one direction about an axis of the actuation shaft member, wherein either one of the engagement portion of each of the contact pins and each engagement projection of the actuation shaft member is made convex and the other is made concave, whereby the actuation shaft member sequentially having two engagement sections in its rotation direction with respect to the contact pins so that the contact portion of each of the contact pins can be brought into contact with or separated from the electrical component at one of the engagement sections of the actuation shaft member and can be slid with respect to the electrical component at the other engagement section of actuation shaft member.
