Patent ID: 7632128

Claim:
An electrical connector assembly comprising: an electrical connector including: an insulative base defining a mating surface, an opposite mounting surface and a plurality passageways running through the mating surface and the mounting surface; a plurality of terminals received in the passageways of the insulative base; and a metallic load plate mounted upon the insulative base and having an opening in a center thereof and a plurality of first holes thereon; a heat sink mounted upon the load plate of the electrical connector, and defining a plurality of second holes; a printed circuit board facing the mounting surface of the insulative base of the electrical connector, and defining a third plurality of holes aligned with the first holes; a fastening device, including: a plurality of first elements inserting into the first holes of the load plate of the electrical connector and the third holes of the printed circuit board to hold the electrical connector and the printed circuit board together; and a plurality of second elements inserting into the second plurality of holes of the heat sink for fastening the heat sink upon the metallic load plate; wherein said load plate of the electrical connector defines a plurality of peripheral sidewalls surrounding said insulative base, and a plurality of foot portions extending outwardly from bottom ends of the sidewalls, and said first holes are disposed on the foot portions; wherein said load plate of the electrical connector defines a plurality of pressing portions extending into the opening thereof from top ends of the sidewalls adapted for resisting against an up surface of an IC package; wherein said second holes of the heat sink aligning with the first holes of the electrical connector, and the second elements are directly fastened to the first elements; and wherein the electrical connector assembly further comprising a backboard mounted under the printed circuit board opposite to the electrical connector, and the backboard further defines a plurality of fourth holes in alignment with corresponding third holes of the printed circuit board for the first elements penetrating therethrough.
