Publication number: 20240162100Abstract: A cover plate may include a plate body and a gasket. The plate body includes a first face and a second face that are disposed back from each other, and the plate body is provided with a first hole. The gasket includes a body part, and the body part is provided with a second hole, and in a direction from the first face to the second face, the first hole penetrates through the plate body, and the second hole penetrates through the body part. When the cover plate is applied to the power module, each pin of the power module may pass through one second hole and be inserted into one first hole in a one-to-one correspondence, and the pin is in interference fit with the corresponding first hole. In this way, the plate body may limit each pin, thereby improving a position degree of the pin.Type: ApplicationFiled: January 19, 2024Publication date: May 16, 2024Applicant: Huawei Digital Power Technologies Co., Ltd.Inventors: Haiwen ZHANG, Zhiling LIU, Yanbo WANG
