Description

Technical Field

[0001] The utility model relates to the field of overlapping copper bar clamps, and more specifically to an overlapping copper bar installation structure for a low-voltage cabinet. Background Art

[0002] The overlapping copper busbar is an indispensable and important component inside the low-voltage cabinet. It is mainly responsible for the connection of external power supply and then branching inside the cabinet. It is generally used for the connection and branching of the main circuit. The overlapping copper busbar needs to be installed inside the low-voltage cabinet by using a copper busbar clamp. Although the existing copper busbar clamp has many advantages in use, it lacks a corresponding lateral adjustment structure at the connection with the overlapping copper busbar. As a result, when there is electrical equipment blocking interference near the direction of the overlapping copper busbar installation area, the overlapping copper busbar cannot be adjusted after installation by the copper busbar clamp, which is not convenient for the smooth avoidance installation of the overlapping copper busbar. Therefore, we propose a low-voltage cabinet overlapping copper busbar installation structure to solve the above-mentioned problems. Utility Model Content
