Claims

[Claims for Utility Model Registration] A first conductor for power supply for supplying power to a power load, and a second conductor for transmitting a strong electric signal superimposed on the DC power supply voltage. A signal transmission plug attached to a wiring duct, which includes a plug body, a plug blade provided in the plug body and in contact with the second conductor, and a DC power supply voltage built in the plug body and transmitted through the plug blade. is supplied and activated, the strong electric signal input through the plug blade is separated from the DC power supply voltage, converted into a weak electric signal, and sent to an external signal device, and the weak electric signal output from the external signal device is converted into a strong electric signal. and a signal conversion circuit for transmitting the signal to the plug blade.
