Description

Reusable wiring lug

Technical Field

The utility model belongs to the technical field of electric power tools, and particularly relates to a reusable wiring lug.

Background

The high-voltage grounding wire is very important in electrician work and is an important measure for ensuring personal and equipment safety. The annealed copper wires at the connection part of the wiring copper nose and the annealed copper wires are easy to strain and break strands, so that the safety management risk is increased.

Prevent the sheath protection annealed copper line at current wiring copper nose technical use, however in actual operation, because the influence of operational environment and use reason, prevent that the sheath of breaking does not solve the annealed copper line broken end problem, and damage the back because the difficult discovery annealed copper line that breaks of sheltering from of sheath produces the potential safety hazard. Thus, there is a higher security management risk.

When the wiring copper lug is replaced, the wiring copper lug and the broken strand annealed copper wire are cut off, and a new wiring copper lug is replaced by crimping, so that the wiring copper lug is replaced with higher cost. But in actual operation, manufacturers use oxygen-free copper to replace red copper, and slow down the strain oxidation of the copper wire by improving the ductility and the durability, but the cost is high and the problem of easy strain caused by repeated bending when the connecting part of the connecting copper nose and the soft copper wire is used and stored is not fundamentally solved.

The utility model aims to provide a reusable wiring lug, and aims to solve the problem that in the prior art, a wiring copper lug and a broken strand annealed copper wire are cut off, a new wiring copper lug is replaced, and the cost is high.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a reusable wiring lug comprises a wiring board and a wiring barrel which are integrally arranged, wherein a wiring hole is formed in the wiring board, a first end of the wiring barrel is opened, and a second end of the wiring barrel is connected with the wiring board;

the wire connecting device is characterized in that a threaded hole is formed in the wall of the wire connecting cylinder, a crimping bolt is arranged in the threaded hole, a first end of the crimping bolt is located outside the wire connecting cylinder, and a second end of the crimping bolt is located in the wire connecting cylinder and used for crimping a cable.

Optionally, a gasket is arranged at the second end of the crimping bolt for crimping the lead.

Optionally, the gasket is an arc-shaped piece, and a back of the arc-shaped piece is used for contacting with the second end of the crimping bolt.

Optionally, the crimping bolt is arranged along a radial direction of the wire barrel.

Optionally, the crimping bolt is a butterfly bolt.

Optionally, the wire connection nose is a wire connection copper nose or a copper-aluminum composite wire connection nose.

Optionally, reinforcing plates are arranged around the threaded holes and welded to the outer surface of the connecting cylinder.

Optionally, two wiring holes are provided.

The utility model has the following beneficial effects:

the utility model adopts the reusable wiring nose, only the crimping bolt needs to be screwed off when the grounding wire is broken, the broken strand part is removed, and the wire is not required to be replaced together with the wiring copper nose, thereby greatly reducing the replacement cost.
