  • Patent number: 8932082
    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: 20140357098
    Abstract: An electrical connector assembly includes an insulative housing, a number of contacts, a least a first PCB electrically connecting with the contacts, a pair of restriction sections, and a pair of fastening elements. The insulative housing comprises an upper wall, a lower wall opposite to the upper wall, and a pair of sidewalls connecting with the upper and lower walls. The contacts are received in the insulative housing. The first PCB comprises a pair of side sections partially surrounding the insulative housing. The pair of restriction sections is connected with the sidewalls of the insulative housing and partially overlaps with side sections of the first PCB. The pair of fastening elements respectively passes through the restriction sections and the side sections of the first PCB to align and position the relative position between the insulative housing and the first PCB for achieving more reliably electrical connection between the first PCB and the contacts.
