[0001] The invention relates to the technical field of outdoor line detection equipment, in particular to an outdoor cable connection joint. Background Art

[0002] Wire hanging is a common problem during wire inspection and installation. Since the wires in the air are generally bare wires without outer skin, the existing hanging method is to connect one end of the wire to be hung with one end of a long pole, and then insert one end of the long pole with one end of the wire into the wire in the air, and then pull out the long pole, so that one end of the wire remains in the air.

[0003] This operation process is very troublesome and the success rate is not high. Even if the long pole is inserted, the connection between the wire and the overhead outdoor cable is not firm and there is a risk of falling off.

The limit buckle 4 limits all degrees of freedom of the driven wheel 41 except the degree of freedom of rotation around its own axis. The guide rod 7 is guided by the first active guide sleeve 5 or the second active guide sleeve 6 and contacts the first switch 51 and the second switch 61 respectively, thereby triggering the first switch 51 or the second switch 61, so that the driving motor 3 drives the driving wheel 31 to rotate. The first switch 51 and the second switch 61 are respectively connected to the driving motor 3 by electrical signals through wires. The first switch 51 controls the driving motor 3 to rotate forward, and the second switch 61 controls the driving motor 3 to rotate reversely. The forward or reverse rotation of the driving wheel 31 drives the driven wheel 41 to rotate forward or reverse, and then the driven wheel 41 drives the screw rod 42 to rise or fall, so that the limit block 43 approaches the hook 2 or moves away from the hook 2, thereby locking or opening the hook 2.

[0020] The hook 2 is made of conductive metal, and one end of the cable to be towed is electrically connected to the hook 2. For insulation, the guide rod 7 is made of insulating material.

[0021] When connection is required, first insert the upper end of the guide rod 7 into the second active guide sleeve 6, trigger the second switch 61, drive the motor 3 to reverse, the screw rod 42 to descend, the limit block 43 to move away from the opening of the hook 2, and then use the guide rod 7 to hang the outdoor cable connector on the exposed outdoor cable through the hook 2, so that the cable is electrically connected to the cable. Then insert the guide rod 7 into the first active guide sleeve 5, trigger the first switch 51, drive the motor 3 to rotate forward, the screw rod 42 to descend, the limit block 43 to move close to the opening of the hook 2, and then lock the outdoor cable connector to the outdoor cable.
