  • Publication number: 20140127945
    Abstract: An electrical connector mountable on a printed circuit board includes an insulative housing and pairs of power contacts. Each power contact has a contacting portion, a tail portion and an intermediate portion interconnecting the contacting portion and the tail portion. The intermediate portion is provided with a retention element in a rear edge thereof extending towards an inside wall of a passageway defined through the insulative housing. Each inside wall of the passageway forms a bump thereon extending along an insertion direction of a complementary connector. The retention element rides on the bump to thereby prevent an involuntarily anti-clockwise movement of the insulative housing with respect to the printed circuit board.

  • Publication number: 20140120784
    Abstract: A power connector includes an insulative housing, at least a pair of power contacts assembled to the at least one contact-receiving passage. The pair of power contacts are arranged oppositely along an up-to-down direction and cooperating with each other. Each of the at least a pair of power contacts includes a cable termination portion, a contacting portion and an intermediate portion connecting the cable termination portion and the contacting portion. One lateral edge of the intermediate portion is a first latching portion, and the other lateral edge of the intermediate portion is a second latching portion. Thus, when the pair of power contacts are assembled together, the first latching portion of one power contact cooperates with the second latching portion of the other power contact, while the second latching portion of the one power contacts cooperates with the first latching portion of the other power contact to form a hollow frame therebetween along an up-to-down direction.
