Patent ID: 8801474

Claim:
An electrical connector comprising: an insulative housing extending along a longitudinal direction, the insulative housing has a mating surface defined thereon, a mounting surface defined opposite to the mating surface and a passageway penetrating through the mating surface, where the mounting surface and the passageway extend along a transverse direction perpendicular to the longitudinal direction; a power contact received in the passageway of the insulative housing, the power contact comprises a pair of contacting portions and a connecting portion connecting the pair of contacting portions, the pair of contacting portions is essentially parallel to each other where a spacing is defined therebetween, the connecting portion comprises a fastening portion which is essentially perpendicular to the pair of contacting portions; and a fastening member separately made from the power contact to fasten securely to the fastening portion; wherein the fastening portion defines a through hole thereon and the fastening member is a screw which is screwed into the through hole; wherein the connecting portion comprises a pair of extending walls extending outwardly from the pair of contacting portions, the width of the fastening portion along the longitudinal direction is greater than the distance between the pair of contacting portions along the longitudinal direction so that the fastening portion provides a reasonable space for the forming of the through hole; wherein each of the extending walls comprises a first wall extending outwardly from the contacting portion and a second wall connecting the first wall and the connecting portion; wherein the connecting portion defines at least one heat-dissipation hole on the boundary between the second wall and the fastening portion, the heat-dissipation hole is in communication with the spacing.
