Abstract
A coupling transformernecessary for power line communication is provided in a connector device. The coupling transformeris formed by winding an AC lineand a signal wirearound an annular toroidal core, which is to be fitted on a tubular partof the connector device. Cutouts for housing the AC lineand the signal wirewound around the toroidal coreare formed in the tubular partof the connector device. Further, a coilis connected to the AC line, a capacitoris connected to an AC line, and the coiland the capacitorare connected to each other with a wireprovided along the AC linesand, whereby a filter circuit is formed.
