Abstract: An independent loading mechanism for use with a CPU connector includes a metallic frame cooperating with a back plate module to sandwich a printed circuit board therebetween. A plurality of screw nut units are provided around the four corners of the frame. A plurality of hollow spacers are secured to the corresponding through holes of the frame so as to allow the corresponding screw nut units moveable relative to the frame along the vertical direction within a range larger than a thickness of the frame, thus avoiding improper interference between the screw nut units and the corresponding screw posts of the back plate module during sequential screwing.

Abstract: An electrical connector includes an insulative housing with a number of through holes extending therethrough, a number of contacts assembled to the insulative housing, and a number of solder balls disposed in the though holes and each is clasped by the tail and insulative housing. Each contact includes a vertical base portion secured to a first side of the through hole, a contact engaging arm extending from a top end of the base portion, and a solder portion extending from a bottom end of the base portion. The solder portion has a wave arrangement below the base portion and projecting from the base portion to a second side of the through hole which opposites to said first side, and a tail extending downwardly from the wave arrangement and capable of moving from the first side to the second side.

Abstract: A socket connector configured with an insulative housing defining a mating interface surrounded with peripheral walls and a mounting surface is disclosed. A plurality of passageways is defined between the mating interface and the mounting surface and having an opening at the mounting surface. The insulative housing includes an encampment associated with each of the passageway at the mounting surface, and includes an extension crossing over an inner wall of the passageway to substantially narrow the opening of the opening. The socket connector furthers includes a plurality of contact terminals each received in the passageway and further includes a curvilinear solder portion extending beyond the mounting surface. And the socket connector further is incorporated with a plurality of solder balls each disposed between the encampment and the curvilinear solder portion.
