  • Patent number: 7052292
    Abstract: The present invention relates to a grounding structure of an electrical connector suitable for high frequency transmitting. The high frequency connector mainly has a connecting part being combined with a plurality of grounding lines to improve the electrical characteristics of the high frequency connector when it transmits a signal. Wherein, the connecting part further comprises a wing portion and a protrusion portion; thereby the connecting part can engage the grounding terminals with the grounding line of the cable to form electrical contact.
    Type: Grant

  • Publication number: 20050085132
    Abstract: A connector pin having a definite width of narrow contact surface to connect to a plug pin along the horizontal direction. The contact surface includes a sliding contact area and a contact terminal. A width of the sliding contact area is smaller than a width of the contact surface. When the plug pin reaches the contact terminal, the width of the sliding contact area is smaller than the contact surface. A transmission capacitance of the plug pin and the connector pin is small for better transmission quality.
