  • Publication number: 20230402775
    Abstract: According to an embodiment, high-frequency signal transmission device includes a connector and a wiring board with two cable ends. The connector includes contact terminals with signal contact terminals and ground contact terminals. In a wiring board, signal contact pads, ground contact pads and one or more ground layers are formed on at least one of the cable ends. The ground contact terminal includes an arm portion bent so as to locally abut against the ground contact pad at a contact portion. The contact portion of the arm portion is positioned so as to (i) at least partially abut against a surface of a covering portion of the ground contact pad covering the first penetrating electrode directly above the first penetrating electrode, or (ii) abut against the ground contact pad near an outer periphery of the covering portion, when the wiring board is electrically connected to the connector.

  • Patent number: 7896705
    Abstract: An interface connector makes parts to be fitted by insertion hold the state where a receptacle and a plug are fitted, and removes the plug easily from the receptacle when load is applied to the plug from a direction other than the insertion direction. In the interface connector (10), the plug (100) has an inserting projection part (114) in which a plurality of plug terminals (120) are disposed in upper and lower faces (114b and 114c).

  • Patent number: 7252549
    Abstract: A connector includes a receptacle 1 to be mounted on a substrate 11 and a plug 5 adapted to be connected to the receptacle 1. The receptacle 1 has a shield case 2 provided with connection terminals 31 therein, and the plug 5 has a shield case 6 provided with connection terminals 71 therein. The shield case 6 of the plug 5 is adapted to be inserted into the shield case 2 of the receptacle 1 when the plug 5 is connected to the receptacle 1, at which the connection terminals 71 of the plug 5 are electrically connected to the connection terminals 31 of the receptacle 1. A tongue portion 23 is provided on a bottom surface of the shield case 2 of the receptacle 1 and a recess 63 is formed on a bottom surface 61 of the shield case 6 of the plug 5 so that the tongue portion 23 is fitted into the recess 63 when the plug 5 is connected to the receptacle 1, which serve as an erroneous insertion preventing and guiding mechanism.
