  • Publication number: 20110294362
    Abstract: In one embodiment of the present invention, there is provided an electrical connector comprising an insulative housing having a longitudinal base with a first side and a second side. Extending from the base at the first side is a tongue portion having a first tongue section and a second tongue section, both sections having a first face and a second face. A plurality of passageways are defined on the first faces of both sections. Each of the passageways has a recess located at one end and a plurality of conductive contacts are received in the passageways. Each contact comprises a mating section, a mounting section and a retainer section bridging the mating section to the mounting section whereby the mating section of the contact is free to flex into the recess. In another embodiment of the present invention, there is provided an electrical connector having a socket extending from the base at the second side.
