AI Technical Summary
The existing method of applying adhesive to the connection of shielded busbars in switchgear is not precise enough, which can easily lead to adhesive overflow or uneven distribution, affecting the sealing effect and connection reliability.
The busbar installation section is designed with a glue channel and a glue outlet. The glue channel controls the flow of glue, ensuring accurate distribution at the connection between the busbar and the switch cabinet panel and at the screw mounting points. At the same time, screw guide posts are used to ensure precise alignment of the mounting holes.
It improves the sealing effect and the stability and reliability of the connection, ensures uniform distribution of adhesive, and enhances the connection reliability between the busbar and the switchgear.
