Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically to a multi-functional integrated busbar structure for low-voltage distribution boxes. Background Technology

[0002] Busbars refer to the copper or aluminum busbars that connect the main switch and the switches in each branch circuit in a power supply system. They are insulated and their main function is to serve as conductors.

[0003] Upon investigation, it was found that currently, commonly used busbars, within a limited space, require multiple bends in the busbar body to allow the input or output pins to overlap with the terminal connection surfaces of other devices. This results in significant stress on the connected devices after the busbars have been bent multiple times, affecting internal components and making the busbar connection cumbersome. To address these issues, a technological innovation is proposed based on existing devices. Utility Model Content
