  • Publication number: 20140187064
    Abstract: A low-profile electrical connector includes an insulative housing, a plurality of contacts and a pair of mounting pieces positioned at opposite sides of the insulative housing. The insulative housing includes a half-opened plug-receiving space. Each contact includes a fixing portion, a deformable contacting portion extending into the plug-receiving space and a soldering portion for being mounted to a circuit board. Each mounting piece includes a retaining portion, a bending portion extending sidewardly from the retaining portion and a mounting portion parallel to the retaining portion. The mounting portions are adapted for being fixed to the circuit board in order that when a plug is inserted into the plug-receiving space, the mounting portions replace the soldering portions to bear a great deal of impact force.

  • 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.
