<p>The present invention provides a power line installation type power line communication relay device. The device includes a body (10) including a power line modem part (14) and a power supply part (18); combination parts (20,40) combined with an N-phase power line; and a connecting part (30) connecting the combination part (20) with the body (10) by using hinge combination. In the body (10), an N-phase connecting unit (19) to electrically connect to the N-phase power line (N) through the connecting part (30); and a signal line connecting unit (12), into which a signal line probe line and a power line probe line are inserted to electrically connect to power lines, used as a power line and a power line communication line, among power lines, are installed. In the combination parts (20,40), conductive contact members (26,28; 46,48), conducted with the N-phase power line (N) when combined with the N-phase power line, protrude. The conductive contact members (26,28; 46,48) are conductively connected to the power supply part (18) and the power line modem part (14) through the N-phase connecting unit (19) of the body (10) by using conducting members (23,27,29; 43,47,49), formed in the combination part (20) and the connecting part (30), as a medium.</p> |
