A plug for use in a wiring duct

Abstract

A wiring duct plug that does not have a movable part for switching and thus has a higher operational reliability is provided. A plug (wiring duct plug) 2 for use mounted in a wiring duct, in which a plurality of conductive lines are installed, comprises a rotatable rotator 17, a pair of non-movable electrode terminals 2a-c′ and 2d′, and a plurality of movable electrode terminals 2a to 2d. The plurality of movable electrode terminals 2a to 2d rotate with the rotator 17 and are placed either at a connection position for electrically coupling the plurality of conductive lines and the pair of non-movable electrode terminals 2a-c′ and 2d′, or at a release position for releasing electrical connection. At the connection position, among the plurality of movable electrode terminals 2a to 2d, the plurality of movable electrode terminals 2a to 2c whose number of terminals is one or more less than the number of the conductive lines respectively connect to conductive lines whose number of lines is one or more less than the conductive lines, and are joined into one at the base end portion and coupled to the one non-movable electrode terminals 2a-c′. The remaining movable electrode terminal 2d couples the remaining conductive line to the other non-movable electrode terminal 2d′.
