The method of reducing the wire passing space of the second wiring hole is: the wire nut is also provided with a locking device, and by adjusting the locking device, the wire passing space of the second wiring hole can be reduced so that the wire passing through the second The bare wire of the cable terminal of the wiring hole is locked in the second wiring hole. The advantage of this structure is that the design is flexible and can be repeatedly installed and disassembled.

Preferably, the structure of the electrical connector is as follows: the electrical connector is provided with a ring that matches the electrical terminal, and the electrical connector is fixed at the electrical terminal by a locking bolt that matches the ring. The advantage of this structure is that the structure is simple, the connection is tight, and it has good versatility with the connection port of the current electrical terminal.

Preferably, an insulating covering layer is provided outside the connecting terminal body, preferably the material of the insulating covering layer is plastic, and the insulating covering layer can protect the connecting terminal body and has the function of insulating protection.

The beneficial effects of the waterproof terminal of the utility model are: simple structure, easy processing, easy installation and disassembly, good safety, strong versatility, and can prevent backflow of rainwater and conductive impurities.

The conception, specific structure and effects of the present utility model will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present utility model.
