Abstract: An LGA connector assembly (1) includes an insulative base (10) receiving a number of electrical contacts (14), a metal reinforcement (11) covering the base, and a lever (13) and a metal clip (12) pivotally mounted to two opposite sides of the base respectively. The base defines a cavity (100) in a middle thereof, and eight rectangular holes (1031) near the cavity. The reinforcement includes a planar portion (111) parallel to a top of the base, and eight projecting members (1110) depend perpendicularly from the planar portion. Each projecting member is able to be fittingly received in the corresponding hole of the base, to mount the reinforcement to the base. Thus, during rotating the lever to engaging with the metal clip to tightly attach a CPU in the cavity of the LGA connector assembly, the base is enough hard to withstand forces from the clip and the lever.

Abstract: An LGA socket connector (1) comprises a rectangular base (2), a plurality of terminals (5) received in the base, and two reinforcing members (4) attached to the base. Tow side walls (23) are formed on opposite ends of the base. Each reinforcing member has an elongate base plate (40), a first side plate (42) bent perpendicularly inwardly from a top edge portion of the base plate and a second side plate (44) bent perpendicularly inwardly from a bottom edge portion of the base plate. With this configuration, the reinforcing member is formed from a sheet of metal with very little wastage. Further, the reinforcing members each have a “C”-shaped cross-section. Thus the reinforcing members each can attain a good rigidness along a length thereof. The two reinforcing members are respectively attached to the side walls of the base, thereby the base is effectively reinforced.

Abstract: A land grid array socket (1) includes an insulative base (2) mounted on a printed circuit board, a metal clip (3) pivotably engaged on the base, and a lever (4) for fastening the clip onto the base. The clip (3) and the lever are respectively mounted on two opposite ends of the base to fasten an LGA package. A reinforcing plate (5) made of rigid material is insert molded into the base. The reinforcing plate is generally a rectangular frame, and it includes four integrated sides (51). A substantially rectangular opening (52) is defined among the sides. Therefore, the rigidity of the base is improved, and the deformation or warpage under the pulling forces on two opposite ends of the base is diminished, thereby ensuring steady electrical connection between the contacts pads of the LGA package and respective contacts of the base.
