[0062] In this embodiment, the working principle of the industrial robot joint cable is as follows: the male docking devices 5 at both ends of the cable 2 4 are respectively slid into the two mounting shells 6 from the two openings 2, and then the corresponding two electric telescopic rods 10 are started, and the two electric telescopic rods 10 respectively drive the two clamping arc plates 11 to approach each other, and clamp the corresponding male docking devices 5. When the clamping arc plates 11 approach each other, the fixed bent rod 12 and the telescopic bent rod 13 slide and cooperate. After the male docking device 5 is clamped, the threaded rod 8 is rotated, and the connecting frame 9 is connected with the rotation of the threaded rod 8. The two corresponding electric telescopic rods 10 and the male docking device 5 are driven to move toward the direction of the female docking device 3, so that the male docking device 5 and the female docking device 3 are docked, and while the male docking device 5 moves, the sealing arc plate 15 moves toward the direction of the opening 2, and then the two sealing arc plates 15 slide into the corresponding opening 2, and the two elastic rods 14 respectively support the corresponding fixing frames 16, so that the two sealing arc plates 15 are more fixed, and then the pushing tube 22 is pushed to move toward the direction of the card plate 19, and the locking plate 23 is driven to move by the pushing tube 22, and the locking plate 23 pushes the two clamping plates 19 to rotate on the fixed shaft 18.

When the locking sleeve 24 contacts the locking plate 23, the contact plate contacts the fixing collar. At this time, the locking sleeve 24 will push the card plate 19 to rotate on the fixed shaft 18, so that the distance between the two card plates 19 is maximized, and then the push tube 22 is pulled, and the fixed ring pushes the contact plate to move away from the card plate 19, and drives the locking plate 23 and the locking sleeve 24 to push the two card plates 19 and move away from the two card plates 19, and then the male connector 5 and the female connector 3 are disassembled, and during normal operation, the fan 26 blows air into the installation shell 6, and filters the air through the filter cover 27 to cool the inside of the installation shell 6.
