CN223872008U - A horizontal busbar with a copper busbar clamping structure - Google Patents

Abstract

This utility model discloses a horizontal busbar with a copper busbar clamping structure, including a busbar trunking body, copper busbars, a thin film, and a fixing device. The four components work together to achieve their functions. The overall layout is horizontal with side wiring, using lateral space to save vertical space. The combination of the thin film, copper busbars, and busbar trunking body enables rapid heat dissipation of the busbar. In addition, the fixing device on the busbar trunking body simplifies the overall structure and allows for rapid on-site installation. Chamfers are provided at the turning points of the copper busbar fixing groove, so there are no sharp edges in contact with the thin film, eliminating the risk of being scratched. It utilizes the advantages of side wiring in horizontal busbars and uses the clamping blocks and end caps of the fixing device to fix the middle and sides of the copper busbar, solving the disadvantage of difficult thermoforming of horizontal busbars.
