They are commonly used in urban underground power grids, outgoing lines from power stations, internal power supply in industrial and mining enterprises, and underwater power transmission across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electrical energy in the main lines of the power system, including power cables of various voltage levels from 1 - 500 kV and above, and various insulations. When wiring and repairing cables, cable auxiliary connectors are often needed. Currently, when wiring cables, workers often need to manually operate the auxiliary connector for crimping, resulting in a decrease in cable wiring efficiency.

A rotating column 6 is fixedly connected to the top end of the clamping base plate 19. The lower connection terminal 7 and the upper connection terminal 8 are rotatably sleeved on the outer arc surface of the rotating column 6;

[0025] On the upper surface of the installation base plate 1, there is a wiring component for driving the lower connection terminal 7 and the upper connection terminal 8 to approach for pressing and wiring; By starting the servo motor 12 to drive the rotating shaft 16 to rotate, the rotating shaft 16 drives the upper driving plate 15 and the lower driving plate 17 to rotate, thereby pushing the lower extension plate 3 and the upper extension plate 10 to move away from each other. And the lower extension plate 3 and the upper extension plate 10 take the rotating column 6 as the center, driving the lower connection terminal 7 and the upper connection terminal 8 to approach, so as to press and wire the cable through the lower connection terminal 7 and the upper connection terminal 8, thus avoiding the need for staff to manually operate the wire connector, and further improving the cable wiring efficiency and avoiding the staff being injured by the wire connector.

[0026] Preferably, the wiring component includes a limiting ring 2, a support block 11, a servo motor 12, a driving rod 13, a rotating shaft 16, a connecting plate 18 and a driving module. The support block 11 is fixedly installed on the upper surface of the installation base plate 1. The servo motor 12 is bolted to one side of the support block 11.

The connecting plate 18 is fixedly connected to the driving rod 13. The support block 11 supports the servo motor 12 and the rotating shaft 16. By the fixed connection between the rotating shaft 16 and the limiting ring 2 and the sliding sleeve connection with the driving rod 13, and the sliding groove corresponding to the rotating shaft 16 is arranged on the surface of the driving rod 13, the technical effect of driving the limiting ring 2 to rotate is realized, and when the driving rod 13 moves, the rotating column 6 is driven to move, solving the technical problem of driving the upper driving plate 15 and the lower driving plate 17 to rotate without manual operation by the staff.

[0027] Specifically, the driving module includes an upper driving plate 15 and a lower driving plate 17.
