[0062] In this embodiment, the working principle of the industrial robot joint cable is as follows: the male connectors 5 at both ends of the cable 2 4 are slid into the two mounting housings 6 from the two openings 2, and then the corresponding two electric telescopic rods 10 are started. The two electric telescopic rods 10 respectively drive the two clamping arc plates 11 to approach each other to clamp the corresponding male connector 5. When the clamping arc plates 11 approach each other, the fixed bent rod 12 and the telescopic bent rod 13 slide together. After the male connector 5 is clamped, the threaded rod 8 is rotated. As the threaded rod 8 rotates, the connecting frame 9 Drive the corresponding two electric telescopic rods 10 and the male docking device 5 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 respectively support the corresponding fixing frame 16 through the two elastic rods 14, so that the two sealing arc plates 15 are more fixed, and then push the pushing tube 22 to move in the direction of the card plate 19, and drive the locking plate 23 to move through the pushing tube 22, and the locking plate 23 pushes the two card plates 19 to rotate on the fixed shaft 18. When the locking plate 23 passes through the two card plates 19, the four coil springs 20 respectively drive the two card plates 19 to reset, blocking the locking plate 23 through the card plates 19, and the fixed plate is blocked on the supporting shell 21. When the locking plate 23 and the card plate 19 are separated, the fixing rod 25 is pushed, and the fixing rod 25 drives the locking sleeve 24 to move toward the locking plate 23, and the multiple fixing blocks slide in the multiple openings 4. 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 collar 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.
