  • Patent number: 10468808
    Abstract: An electrical plug connector includes a plurality of terminals and an insulator, a pair of grounding latches, a shielding spring and a shielding shell. Each of the terminals has a contacting segment and an elastic segment. Each of the contacting segments has a stopping face. The insulator partially covers the terminals and has a plurality of stopping edges. When the electrical plug connector is inserted into an electrical receptacle connector, shape deformation of each of the elastic segments shifts the corresponding contacting segment until the corresponding stopping edge is against the corresponding stopping face, and each contacting segment does not protrude from the insulator. When the electrical plug connector is not inserted into the electrical receptacle connector, shape recovery of each of the elastic segments restores the corresponding contacting segment and the corresponding stopping edge is away from the stopping face.

  • Patent number: 10079456
    Abstract: An electrical receptacle connector includes a metallic shell, an insulated housing, upper-row receptacle terminals, and lower-row receptacle terminals. The insulated housing is in the receptacle cavity of the metallic shell. The receptacle terminals are held in the base portion and the tongue portion. The tail portions of the power terminals and the tail portions of the ground terminals have three bent portions, i.e., the first bent portion, the second bent portion, and the third bent portion. The bent portions allow the terminals to have different and non-parallel delivering paths for electromagnetic waves, so that the signals do not interfere with each other easily.
