In power engineering, cables need to be connected in order to transport electricity over long distances.

[0003] Traditionally, when wiring cables, fixed wiring terminals are generally used for wiring, which is normal cable wiring; however, some cables have been damaged or even disconnected, and the single wires inside need to be manually wired one by one. Generally, staff manually wire the wires, fix the wire ends one by one, and then wrap them with transparent tape. This operation requires multiple tools and is very inconvenient, and the wiring efficiency is low.
