The contact includes an upper interface that is biased in a manner to form a shorted electrical path between the module and circuit board when the module is biased downward onto the contact.

Abstract: A socket (10) has a base member (20), a cover member (30) which is mounted for alternating motion toward and away from base member (20), a plurality of contacts (40) having an end fixed to the base member (20), a contact regulating member (50) that regulates the position of the movable ends (42, 92) of the contact and an adaptor (60) having a seating surface, the adaptor which is mounted for alternating motion toward and away from the contact regulating member (50). When adaptor (60) is removed from the contact regulating member, the movable ends of the contacts do not protrude through the seating surface and when adaptor (60) has been moved toward the contact regulating member (50), the movable ends of the contacts protrude from each through-hole (65) of adaptor (60) for engagement with the solder balls of a BGA device (11), placed on the adaptor (60). The cover member is linked to the base member and latches (70) having a BGA device pressing tip (72) are rotatable with movement of the cover.

Abstract: A socket for an electrical part has a socket body, in which a number of contact pins are arranged adjacently each other so as to contact terminals of an electrical part. A movable member is disposed so as to elastically deforming the contact pins, and an operation member is also disposed to be vertically movable to thereby move the movable member. In such socket, each of the contact pins is provided with a pair of elastic pieces contacting the terminal of the electrical part, at least one of the elastic pieces is elastically deformed by the movement of the movable member so as to be contacted to or separated from the terminal of the electrical part, and when at least one of the elastic pieces is elastically deformed and separated from the terminal of the electrical part, the elastic pieces of the adjacent contact pins pass each other without contacting.

Abstract: A contact pin assembly for a socket for electrical parts comprises a plurality of contact pins provided for a socket body of a socket for electrical parts and a connection member, formed separately, connecting all the contact pins with a predetermined distance between adjacent ones. The predetermined distance is made substantially equal to a distance between adjacent ones of terminals provided for an electrical part which is held in the socket body.
