Abstract
A wiring duct plug that does not have a movable part for selecting any of a plurality of conductive lines, and has a high operational reliability is provided. A wiring duct plug can be directly connected to a respectively corresponding conductive line, and comprises a plurality of movable electrode terminals, rotating together with a rotator. At the connection position, at least two but not all of the plurality of movable electrode terminals are joined into one at the base end portion and electrically coupled to one of non-movable electrode terminals, and the remaining movable electrode terminal is electrically coupled to the other non-movable electrode terminal.
Claims7
A wiring duct plug for use mounted in a wiring duct in which a plurality of conductive lines are installed, the plug comprising:
- a rotatable rotator;
- a pair of non-movable electrode terminals;
- and
- a plurality of movable electrode terminals, rotating with the rotator and placed either at a connection position for electrically coupling the plurality of conductive lines to the pair of non-movable electrode terminals, or at a release position for releasing electrical connection,
- wherein, when placed at the connection position, among the plurality of movable electrode terminals, at least two but not all of the plurality of movable electrode terminals are capable of being directly coupled to corresponding ones of the plurality of conductive lines, and are joined into one at a base end portion and coupled to one of the non-movable electrode terminals, and one or more of remaining movable electrode terminals of the plurality of movable electrode terminals are capable of directly coupling to a corresponding one or more of remaining conductive lines and to the other non-movable electrode terminal.
