  • Publication number: 20210005993
    Abstract: There are provided a connector having excellent transmission characteristics, and a method for manufacturing such a connector, by which a connector can be manufactured more easily than in the conventional techniques, and thus its manufacturing cost can be reduced. A conductor base member including central terminal portions to form signal terminals, a grounded conductor portion to form a grounded conductor, connecting portions for connecting between the central terminal portions and the grounded conductor portion so as to integrate them together is integrally formed with an electrically conductive material. Then, the conductor base member is integrally fixed to the housing, and the connecting portions are cut to configure the central terminal portions as the central terminals and configure the grounded conductor portion as the grounded conductor, thereby obtaining a plug.

  • Patent number: 10847906
    Abstract: A connection switching device is provided which connects a plug, having a plug pin connected to an inspecting circuit, to a receptacle connector connecting an antenna and a transmission/reception circuit, and switches a connection to a parallel connection where the inspection circuit is connected to the antenna and to the transmission/reception circuit. The receptacle connector includes a first contact, a second contact, and a normally closed terminal that is brought into elastic contact with the first contact and the second contact. The plug includes a first plug pin being brought into contact with the first contact, a second plug pin being brought into contact with the second contact, and an insulating projection being inserted between at least one of the first and second contacts and the normally closed terminal to insulate between the at least one of the first and second contacts and the normally closed terminal.
