Description

Technical Field

[0001] The utility model relates to the technical field of electric power installation, in particular to an electric power installation lead clamp. Background Art

[0002] The lead clamp is a commonly used electrical hardware. Its main structure includes an upper wire clamp, a lower wire clamp and a bolt assembly. Its working principle is to insert the main wire into a clamp hole in the lead clamp, insert the shunt wire into another clamp hole, and clamp the main wire and the shunt wire through the bolt assembly, the upper wire clamp and the lower wire clamp. The upper wire clamp and the lower wire clamp themselves have conductive properties. In this way, the lead clamp not only realizes the spatial merger of the main wire and the shunt wire, but also realizes the power transmission between the two.

[0003] When the existing lead clamps are used to clamp multiple leads, the multiple lead clamps are often adjusted separately and then combined and connected to save installation space. However, this installation method requires the staff to adjust the lead clamps multiple times, which is time-consuming and greatly reduces the installation efficiency.

[0004] Therefore, we propose an electric power installation lead clamp to solve the above problems. Utility Model Content

A plurality of limit grooves are provided on the outer side of the positioning sleeve 4. The limit blocks 5 are slidably installed on the inner sides of the plurality of limit grooves. A steel nail assembly is provided on the inner side of the positioning sleeve 4.

[0026] In this embodiment, the installation mechanism also includes four installation columns 13, two one-way bases 12 and a two-way base 14. Two one-way bases 12 and a two-way base 14 are slidably installed on the bottom inner wall of the clamp housing 1. Two of the four installation columns 13 are respectively fixedly installed on the top of the corresponding one-way base 12, and the remaining two installation columns 13 are fixedly installed on the top of the two-way base 14.
