Abstract
A coupling transformer 15 necessary for power line communication is provided in a connector device 3. The coupling transformer 15 is formed by winding an AC line 11 and a signal wire 13 around an annular toroidal core 15a, which is to be fitted on a tubular part 32 of the connector device 3. Cutouts for housing the AC line 11 and the signal wire 13 wound around the toroidal core 15a are formed in the tubular part 32 of the connector device 3. Further, a coil 17a is connected to the AC line 11, a capacitor 17b is connected to an AC line 12, and the coil 17a and the capacitor 17b are connected to each other with a wire 17c provided along the AC lines 11 and 12, whereby a filter circuit is formed.
