  • Publication number: 20210210913
    Abstract: An electrical connection plug includes an insulating base, a metal housing, and a fitting portion. The left and right sides of the metal housing are shaped to have semi-circular arc structures. The upper and lower surface and the left and right sides of the metal housing that perpendicularly correspond the fitting space are formed to have hole-free structures. The height of the two contact interface substrates is smaller than the height 0.9 mm of a fitting interface substrate of a biased electrical connection plug having the minimum height specification specified by USB Association and larger than 0.28 mm.

  • Patent number: 10756488
    Abstract: A bidirectional electrical connector includes a floating or fixed tongue. One metal plate is deployed without overlap to manufacture upper and lower contact interfaces and a metal tongue. The tongue and the H-shaped limit structure can eliminate the short-circuited problem when the bidirectional electrical connector is docked with a complementary electrical connector. The metal tongue or the structure with the metal reinforcement sheets added into the insulation tongue can optimize the use of the bidirectional electrical connector. A snap structure on a metal housing facilitates smooth docking, and the docked state cannot easily get loose, thereby enhancing the docking stability.
