AI Technical Summary
The insulating film of the laminated copper busbar is prone to warping during installation, which can obstruct the mounting holes and affect the subsequent assembly of components.
Design an insulating film including a protrusion that, after installation, extends out from the insulating film portion and is pressed down to expose the screw holes on the laminated copper busbar, facilitating the installation of the absorption capacitor.
The protruding design improves the ease of component assembly while ensuring insulation reliability and safety.
