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.

An electrical connector includes at least two electrical connector elements extending side by side along a longitudinal direction, each of the electrical connector elements being connectable to a respective wire of an associated electrical cable. An electrical device is in electrical contact with the respective electrical connector elements. A flexible carrier bears inwardly against the electrical connector elements. The electrical device is mounted on an inner side of the flexible carrier which faces the connector elements.

To allow a fit-in state between electrical connectors to be firmly maintained, elastic arm-shaped members provided to a conductive shell member so as to elastically displace to a direction orthogonal to a fit-in direction of a mating connector are each provided with an engaging piece having a connector contact surface which the mating connector faces from the depth in the fit-in direction and a shell contact surface which a part of the conductive shell member faces from the front in the fit-in direction. When an external force is applied to the mating connector in a fit-in state to a removing direction opposite to the fit-in direction, the engaging piece is brought into a state of being interposed between the mating connector and the conductive shell member. This avoids a situation in which the engaging piece is removed from the mating connector to cause a lock release.

An electrical connector for a multi-wire electrical cable includes at least two cable-side electrical contact elements including associated electrical terminals to each of which is to be connected a wire of the electrical cable. At least two output-side electrical contact elements, from each of which projects an electrical connector element by which an electrical connection can be established to a mating connector. An electrically conductive carrier body is disposed between the cable-side contact elements and the output-side contact elements. The electrically conductive carrier body carries an electrical device by which the cable-side contact elements and the output-side contact elements are electrically connected to each other. The electrical device is supported by the carrier body without any of the cable-side contact elements or the output-side contact elements being in electrical contact with the carrier body through the electrical device.
