Connector lug protection device for electrical engineering

Abstract

The invention belongs to the technical field of electrical engineering, particularly relates to a connector lug protection device for electrical engineering, and provides the following scheme for solving the problems in the prior art: the connector lug protection device comprises a first sheath and a second sheath, one end of the first sheath is provided with a first connecting end, and one end ofthe second sheath is provided with a second connecting end matched with the first connecting end; an air suction hole is formed in the outer wall of the side face of the second sheath, a valve cylinder is fixedly connected to the inner wall of the side face of the air suction hole, a cap is connected to the outer wall of the side face of the valve cylinder through threads, a check ring is fixedlyconnected to the inner wall of the side face of the valve cylinder, and a blocking block is arranged on the side, facing the outside of the second sheath, of the check ring. A connecting rod is fixedly connected to the side, facing the interior of the second sheath, of the blocking block, and a pressing block is fixedly connected to the outer wall of one end of the connecting rod. The connector lug can be prevented from being corroded and damaged, whether the connector lug in the protection device is disjointed or not can be judged, maintenance is facilitated, and the surface of an electric wire is prevented from being damaged due to frequent bending.

Description

Technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a terminal protection device for electrical engineering. Background technique [0002] In the power construction, due to the length of the wires, the secondary connection of various wires is usually involved. In actual operation, the insulation layer at both ends of the two wires that need to be connected is usually removed, and the wires are exposed. Wind the bare wires at the end, and then tie them with electrical tape at the winding position to cover all the bare wires. However, the electrical tape ties are easy to expose the wires, and after being exposed to wind and rain, their safety is very poor It is ensured that, especially the adhesive part of the electrical tape will easily fall off when wet, which will bring huge safety hazards. [0003] The prior art discloses a cable terminal protection device, which includes a first box body and a second box body. When the...

[0002] During electric power construction, due to the length of the wires, it usually involves the secondary connection of various wires. Wrap the exposed wires at the end, and then use electrical tape to bind them at the winding position to cover all the exposed wires. However, the electrical tape is easy to expose the wires, and it is not safe after being exposed to wind and rain. Guarantee, especially when the adhesive tape is wet, it is easy to fall off, which will bring huge safety hazards

[0003] The prior art discloses a cable lug protection device, which includes a first box body and a second box body. When the protection device is in use, it protects the lug splice through the fastening of the first box body and the second box body. However, after snapping together, due to the residual humid air in the internal air of the first box body and the second box body, it is easy to cause corrosion and damage at the terminal
