Abstract: Provided is a board-to-board connector including a housing having a protrusion, one or more signal terminals held on the housing such that a contact portion is exposed to the side of the protrusion, a high-frequency signal terminal arranged outside an end portion of the protrusion, and a shell surrounding an outer peripheral portion of the housing and made of a conductive metal material. In the board-to-board connector, the shell integrally includes a GND terminal portion having a plate-shaped board-side shielding portion arranged on a bottom portion outside the end portion of the protrusion and a plate-shaped GND terminal body standing on the protrusion-side end of the board-side shielding portion and arranged closer to the protrusion with respect to the high-frequency signal terminal, and a high-frequency signal terminal housing hole in which the high-frequency signal terminal is arranged is formed in the board-side shielding portion.

Abstract: An electrical connector is provided. The electrical connector is to be attached to a cloth in which a conductive pattern is formed. The electrical connector includes an insulating housing having a boss portion provided on a surface of the housing, where the surface is to be in contact with the cloth, and the boss portion is inserted into the cloth; a connection terminal provided to the housing; and a conductive pad provided around the boss portion on the surface of the housing, where the surface is to be in contact with the cloth, and the conductive pad is electrically connected to the connection terminal. The conductive pad has a protrusion protruding in the same direction as the boss portion of the housing protrudes.

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.

Abstract: A sensor connector compatible with various sensor unit repertoires and capable of improving production efficiency is provided. The sensor connector includes terminal modules to be inserted into a module inserted portion, and commonized pogo pin type terminal module is brought into contact with a connection terminal via slide contact segments capable of sliding relative to the connection terminal exposed to a region closer to the module inserted portion. Thus, the sensor connector can be compatible with the sensor unit 1 having various repertoires by changing, for example, the arrangement and the number of poles of the module inserted portions of the connector housing.

Abstract: There are provided an electrical connection structure, an electrical connection method and an electric connector capable of improving contact reliability, and an electric device including the electrical connection structure. The electrical connection structure includes a swage part configured to sandwich a first electric conductor and a sheet member having a second electric conductor, and an elastic member provided between the first electric conductor and the sheet member in a sandwiching portion of the swage part, the elastic member being configured to connect between the first electric conductor and the sheet member. The first electric conductor and the second electric conductor are electrically connected to each other via a contact point provided in the first electric conductor and a contact point provided in the second electric conductor in the sandwiching portion.

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.
