Abstract

This utility model provides a top cover for a power module, relating to the field of power module technology. It includes a top cover body, with multiple snap-fits on its lower surface and multiple positioning pins on its upper surface. The advantage is that the positioning pins, originally located on the power module housing, are integrated into the top cover. Since the top cover is the final step in power module assembly, this design effectively reduces the risk of damage to the positioning pins during handling and processing, improving production efficiency and product reliability. Furthermore, the one-piece molding design of the top cover ensures the stability of the positioning pins and allows for precise matching with the mounting holes on the PCB, further optimizing the power module assembly process.
