Abstract:
1. An electrical connector mountable on a printed circuit board and adaptable for mating with a complementary connector, comprising: an insulative housing defining a plurality of passageways extending therethrough, wherein each passageway is defined by a plurality of inside walls; and a plurality of pairs of power contacts, wherein each pair of power contacts is received in corresponding passageway of the insulative housing, each pair of power contacts including two separate, opposed power contacts, each power contact comprising a contacting portion, a tail portion and an intermediate portion interconnecting the contacting portion and the tail portion, the intermediate portion provides a retention element in a rear edge thereof extending towards the inside wall of the passageway; wherein each inside wall of the passageway forms a bump thereon extending along an insertion direction of the complementary connector; wherein the retention element abuts against on the bump to thereby prevent an involuntarily anti-clockwise movement of the insulative housing with respect to the printed circuit board; wherein the retention element is formed as a resilient tab having a cantilevered end projecting out from the intermediate portion and extending along a direction away from the contacting portion of the power contact; wherein the inside walls of each passageway comprises a top inside wall, a bottom inside wall and two opposing side inside walls connecting with the top inside wall and the bottom inside wall, and wherein the bump is formed on each of the side inside walls; wherein each passageway defines a pair of upper channels recessed from the top inside wall and a pair of lower channels recessed from the bottom inside wall.
