Patent ID: 7020377

Claim:
A wiring board on which a plurality of primary side light cords and a plurality of secondary side light cords drawn out from a primary side line wire and a secondary side line wire, respectively, are wired, the wiring board comprising: a primary side optical connector that is provided at a terminal of each primary side light cord; a secondary side optical connector that is provided at a terminal of each secondary side light cord; a primary side connector that is provided at a terminal of a primary side conducting wire; a secondary side connector that is provided at a terminal of a secondary side conducting wire; a primary side connector unit that accommodates the primary side optical connectors and the primary side connector; a secondary side connector unit that accommodates the secondary side optical connectors and the secondary side connector; a primary side inductive light emitter that is disposed on the periphery of the primary side connector unit; a secondary side inductive light emitter that is disposed on the periphery of the secondary side connector unit; an optical connection cable in which a wiring light cord and a conducting wire are laid out in parallel, and which has a primary side common connector and a secondary side common connector, each having an optical connector and an electric connector, provided at both ends, respectively; a connection setting data storage that stores connection setting data indicating a set of connectors to be connected; a display driver that reads the connection setting data from the connection setting data storage, and makes a set of the primary side inductive light emitter and the secondary side inductive light emitter emit light; and a connection confirmation section that is connected to the primary side conducting wire and the secondary side conducting wire, and outputs a light extinction signal to turn off the primary side inductive light emitter and the secondary side inductive light emitter to the display driver, when a loop detection or a signal communication is confirmed that indicates that the set primary side connector and the set secondary side connector are connected to the conducting wire.
