AI Technical Summary

Technical Problem

Dust easily gets into the connection points between the inlet head and both ends of the existing lighting busbar, causing corrosion at the connection points and affecting the connection effect.

Method used

The design incorporates a fixed structure and a dustproof structure, including a mounting box, a bidirectional screw, a worm gear mechanism, and a sealing gasket. The worm gear mechanism drives the bidirectional screw to rotate, enabling convenient installation of the busbar trunking. After the inlet head is installed, the sealing gasket covers the connection point to prevent dust from entering.

Benefits of technology

It enables convenient installation of busbar trunking and effective dust prevention, preventing dust from corroding the connection points and extending the service life of the copper busbars.
