  • Patent number: 9548573
    Abstract: A high-speed-transmission connection device includes a male connector, a cable, and a metal protrusion structure. The cable is connected to the male connector. The metal protrusion structure is formed on an outer surface of the male connector. When the male connector is connected to a female connector, the metal protrusion structure is in close contact with the inner surface of the female connector. The metal protrusion structure fills a gap between the male connector and the female connector, and prevents electromagnetic waves from leaking outwardly from the gap.
