Description

Technical Field

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

[0002] A lead clamp is a commonly used electrical hardware fixture. 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 one clamping hole in the lead clamp, and the shunt wire into the other clamping hole. The main wire and shunt wire are clamped together by the bolt assembly, upper wire clamp, and lower wire clamp. The upper and lower wire clamps themselves are conductive. In this way, the lead clamp not only spatially merges the main wire and shunt wire, but also realizes the power transfer between the two. In existing lead clamps, after long-term use, the bolts may loosen, the gap between the upper and lower wire clamps and the cable will increase, and the contact resistance between the lead clamp and the cable will increase accordingly. The conductive performance of the lead clamp itself will be reduced, and the power connection effect between the cables will be greatly reduced.

[0003] The authorized patent with publication number CN219286671U discloses an electric power installation lead clamp, including a mounting base, a mounting frame, and also including fixing bolts, mounting holes, upper clamping members, movable connecting members, fastening bolts, lower clamping members, mounting through holes and clamping adjustment devices, wherein the mounting frame is arranged on the mounting base. Although this application solves the problem that the electric power installation lead clamp on the current market has a relatively simple structure and may become loose after long-term use, resulting in an inability to clamp, the upper clamping members and the lower clamping members on both sides of the application move synchronously, resulting in it being able to only clamp two lead wires of the same diameter. When clamping two lead wires of different diameters, the lead wire with a smaller diameter will have an unstable clamping problem. Moreover, this application is only provided with two clamping members. If multiple strands of wire are encountered, another clamp is required, which increases the difficulty of installation and the device has poor applicability.

[0004] Therefore, an electric power installation lead clamp is proposed. Utility Model Content
