  • Patent number: 7153155
    Abstract: A receptacle connector includes a body and a cover assembled outside the body. The body defines a receiving space and a pair of beams. The end of each beam stretches backward to form a guiding projection. The bottom of the guiding projection is a cambered surface. The cover is bent downward from the front portion to form a pair of elastic arms. The bottom portion of the elastic arm is bent forward to form a finger portion. While a plug connector is inserted into the receiving space of the receptacle connector, the elastic arms press against the pressing portion of the plug connector. When the plug connector is dragged accidentally, the elastic portion of the plug connector slides downward along the finger portion to the cambered surface of the guiding projections, and then slides out of the receiving space to set the plug and receptacle connector apart.

  • Patent number: 7131872
    Abstract: A modular jack connector has an anti-mismating element for preventing incorrect insertion of smaller sized plug connectors. The modular jack connector includes all insulating housing, an insulating terminal seat disposed in the insulating housing, a plurality of contacts disposed in the insulating terminal seat, and two metal anti-mismating elements. One end of each anti-mismating element is fixed to the insulating terminal seat, and the other end is bifurcated with an inner bifurcation bent downward and vertically to form a stopper and an outer bifurcation extending forward and downward to form an inclined guide. The distance between the two stoppers of the two anti-mismating elements is smaller than that between the two inclined guides and equals the width of the smaller sized plug connector. A smaller sized plug connector cannot contact the inclined guides and are blocked by two stoppers to avoid incorrect insertion while it is inserted.
