Cable grounding connection device for electrical distribution box

Abstract

The invention discloses a cable grounding connection device for an electrical distribution box. The cable grounding connection device comprises a lead wire connection part, a grounding connection part and a corresponding protective shell, wherein the grounding connection part is connected with the lead wire connection part; a wire clamping space for clamping a cable grounding bare wire is arranged on the lead wire connection part; the surface for facilitating installation of a grounding wire is arranged on the grounding connection part; and the surface, for clamping the cable grounding bare wire, in the wire clamping space and the grounding connection part have conductivity; the lead wire connection part is used for clamping the cable grounding bare wire through the wire clamping space when used; and the grounding connection part is connected with the grounding wire, so that connection of a cable and the grounding wire is achieved; the cable grounding connection device is simple in structure, easy to process, simple and convenient to install and dismantle, good in safety and high in universality; and the grounding efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric power supply, in particular to a cable grounding transfer device for an electric distribution box. Background technique [0002] In the process of overhauling and maintaining power equipment or cable lines, it is necessary to ensure that the power equipment or cable lines are reliably grounded to prevent the danger to the human body caused by the dangerous voltage generated by a sudden call or the induced voltage generated by adjacent lines. Therefore, it is a very important electrical safety measure to ground the electrical equipment or cable lines through the grounding wire. There are two types of existing low-voltage grounding wires: clip-type grounding wire and duckbill-type grounding wire. The distance between adjacent low-voltage switches is small, and the space of the low-voltage equipment itself is relatively small, so the above two grounding wires cannot be directly grounded in the low-...

AI Technical Summary

Problems solved by technology

There are two types of existing low-voltage grounding wires: clip-type grounding wire and duckbill-type grounding wire. The distance between adjacent low-voltage switches is small, and the space of the low-voltage equipment itself is relatively small, so that the above two grounding wires cannot be directly grounded in the low-voltage distribution box. The disadvantage is that it will expand the scope of power outages, and it is also prone to safety failures such as grounding short circuits.
