[0002] Power safety construction refers to a series of safety measures and construction requirements taken to ensure personal safety and equipment safety during the construction, renovation, operation and maintenance of power projects. In order to ensure construction safety, a construction plan and safety plan are usually clearly defined in the early stage to ensure the safety of personnel, equipment and power facilities during the construction process.

[0003] Wiring operations are common during power construction. The ends of the two wires are usually wrapped with insulating tape, and then the connection is covered and protected by a leakage protection device. However, the existing leakage protection device has certain inconveniences in use.

[0004] First, existing leakage protection devices typically use a sealed casing for protection, clamping and fixing the wires. However, the connected wires are constantly moved during construction, making it difficult for existing leakage protection devices to move the wires. The clamped wires are also prone to wear after long-term use. Furthermore, existing leakage protection devices are usually fixed with screws, making them inconvenient to disassemble and assemble.

[0005] Therefore, we propose a leakage protection device for electrical safety construction of wire ends. Utility Model Content

[0006] In view of the existing technology, the existing leakage protection devices are usually sealed and protected by the shell, and the shell clamps and fixes the wire. However, the connected wire is constantly moved during construction. The existing leakage protection devices are not convenient for wire displacement, and the clamped wire is prone to wear after long-term use. In addition, the existing leakage protection devices are usually fixed with screws, which is inconvenient for disassembly and assembly. In view of the technical problems, the present invention provides a wire end leakage protection device for electrical safety construction.

[0007] The technical solution adopted by this utility model is: a wire end leakage protection device for electrical safety construction, including a base plate and a protective component. The protective component includes a fixed outer ring, a movable inner ring, an elastic ring, a built-in groove, a first movable ball, a telescopic rod, a movable seat, and a second movable ball.
