PROBLEM TO BE SOLVED: To provide a connector capable of easily connecting a water-cooled cable to a plasma thermal spray torch or a power source control device and preventing the water-cooled cable from being twisted even when the plasma thermal spray torch is rotated during its use. SOLUTION: This connector 20 connects the water-cooled cable 30 having a conductor 31 for an electrode connected to the power source control device and a water feed pipe 32 in a coaxial manner to the plasma thermal spray torch 10 for changing a thermal spray material fed from the outside into plasma and spraying it by generating discharge between water-cooled anode 11 and cathode 12. The conductor 31 comprises a conductive pipe 21 connected to the external end thereof, a receiving piece 22 which is integrated with the outer circumferential surface of the conductive pipe 21 to fix the end of the water feed pipe 32 with the conductor 31 for the electrode provided therein, and a cap nut 23 supporting the inner end of the conductive pipe 21 in a turnably abutting manner on the outer end sides of terminal pipes 13 and 14 respectively continued to the anode 11 and the cathode 12, thereby making the receiving piece of the water feed pipe turnable. |
