Anti-breaking and anti-corrosion wire clamp box based on triangle mechanical equilibrium principle

Abstract

The invention provides an anti-breaking and anti-corrosion wire clamp box based on a triangle mechanical equilibrium principle. The wire clamp box comprises a wire clamp, a spring assembly and an insulating sheath. The wire clamp is connected with a wire of the cable. One end of the spring assembly is installed on the cable protection sleeve, and the other end of the spring assembly is connected with the cable clamp to form a triangular structure. The wire clamp and the spring assembly are located in an inner cavity of the insulating sheath. One end of the insulating sheath is arranged on the wire clamp, and the other end of the insulating sheath is arranged on the protection sleeve; and an insulating protective hoop is arranged between the insulating sheath and the spring assembly. The spring assembly is effectively connected with the cable and the cable clamp and is fixed in a triangular mode, and the situation that the wire is broken due to swinging of the cable caused by wind power is counteracted. The insulating sheath and the insulating protective hoop avoid the hooking influence of floating objects such as colored ribbons, aluminum films and the like which can cause interphase short circuit in the air, enhance the insulating protection of exposed parts such as the wire clamp and the lead, and realize the anti-corrosion function by utilizing the physical characteristics of materials and the production process of three-layer injection molding.

Description

technical field [0001] The invention relates to the field of wire clip structure, in particular to a break-proof and anti-corrosion wire clip box based on the principle of triangular mechanical balance. Background technique [0002] Wire clips are iron or aluminum metal accessories that can be fixed on the wires. Most of them need to bear a large pulling force during operation, and some also need to ensure good electrical contact at the same time. The wire clips are mainly divided into: equipment wire clips, Fusible link clamps, holding clamps, terminal clamps, piercing grounding clamps, tightening clamps, insulation piercing clamps, double-ended clamps, lead-in clamps, etc. [0003] In recent years, we have found that the equipment clips installed and used at the connection between switches, knife switches and distribution transformers on the high-voltage side of the 10kV distribution line have the risk of breaking in a windy environment; In the atmospheric environment and...

Problems solved by technology

[0003] In recent years, we have found that the equipment clips installed and used at the connection between switches, knife switches and distribution transformers on the high-voltage side of the 10kV distribution line have the risk of breaking in a windy environment; In the atmospheric environment and undertake the task of transmitting current, the temperature of the clamp is high, and there is a risk of corrosion. The above problems are one of the main reasons for the unstable operation of the power distribution network
