Abstract
A robot includes a robot body and a feeding cable. The robot body is disposed in an explosion-proof region. The feeding cable is disposed in the explosion-proof region, and power is supplied to the robot body through the feeding cable. The feeding cable includes a plurality of wires and a cover. Each of the plurality of wires includes a conductor and an insulator covering the conductor. The cover covers the plurality of wires and has a thickness of equal to or greater than 10 percent of an outer diameter of the feeding cable.
Claims20
A robot comprising:
- a robot body disposed in an explosion-proof region;
- and
- a feeding cable which is disposed in the explosion-proof region and through which power is supplied to the robot body, the feeding cable comprising:
- a plurality of wires each comprising a conductor and an insulator covering the conductor;
- and
- a cover covering the plurality of wires and having a thickness of equal to or greater than 10 percent of an outer diameter of the feeding cable and less than or equal to 15 percent of the outer diameter of the feeding cable.
A robot comprising:
- a robot body disposed in an explosion-proof region and having a case to prevent an inside of the robot body from being exposed to the explosion-proof region;
- a feeding cable which is disposed in the explosion-proof region and through which power is supplied to the robot body, the feeding cable comprising:
- a plurality of wires each comprising a conductor and an insulator covering the conductor;
- and
- a cover covering the plurality of wires;
- a cable ground mounted on the case, the cable ground comprising:
- a first end through which the feeding cable is inserted;
- a second end through which the plurality of wires are pulled out;
- and
- a fixing ring provided in the explosion-proof region to fasten the feeding cable onto the case.
