  • Publication number: 20220037838
    Abstract: An electrical connector is disclosed. The electrical connector has a casing, a terminal seat and a conductive plastic element. The terminal seat is mounted in the casing and has an insulator board and a terminal set. The terminal set has a ground terminal and a high-speed signal terminal set. One side of the conductive plastic element is mounted on an inner wall of the casing and another side thereof passes through the insulator board to be close to the high-speed signal terminal set. When the casing is electrically connected to a ground, the conductive plastic element is electrically connected to the ground through the casing. Therefore, the conductive plastic element may eliminate a noise interference caused by the high-speed signal terminal set during high-speed transmission. A crosstalk and a common-mode interference are also reduced to keep the stability of signal transmission of the electrical connector.
