<p>PROBLEM TO BE SOLVED: To contrive prevention of damage and easiness of exchange of a sensor cable in attaching to/detaching from a sensor. SOLUTION: A laser machining head is provided at the tip end with a sensor for detecting a gap between the tip end and a work, with a cable 7 on the sensor side connected to the sensor through a connector 19, and with a first trunk connector 21 linked to the opposite side of the cable 7 on the sensor side. A cable 9 on a controller side is connected to the first trunk connector 21 through a second trunk connector 31. The opposite side of the cable 9 on the controller side is connected to the controller through a connector 29. Since the second trunk connector 31 is held on the laser machining head through an insulation block near the sensor provided on the nozzle, the cable 7 on the sensor side can be made short and easily exchangeable. The conductor 15 of a connecting part 23 between the connector 19 and the cable 7 on the sensor side is protected by an insulator 25 and linked by a thermal contraction tube 27; therefore, it prevents damage.</p> |
