AI Technical Summary

Technical Problem

Traditional copper clip structures are difficult to provide sufficient support strength in the packaging of medium and high power devices, which makes large copper clips prone to twisting and deformation during transportation and processing.

Method used

The design employs two pairs of connecting ribs. The first pair of connecting ribs extends along the X direction and connects to the outer frame, while the second pair of connecting ribs extends along the Y direction to form a cross-shaped fixation. This increases the copper clip area and provides sufficient support, preventing the copper clip from tilting, twisting, and deforming during transportation and processing.

Benefits of technology

The increased support strength of the copper clip ensures its stability during transportation and processing, preventing twisting and deformation of the copper clip and meeting the application requirements of medium and high power devices.

Abstract

This utility model discloses a copper clip structure and copper strip for use in medium-to-high power devices, comprising: a copper clip body and a fourth part. The copper clip body includes a first part, a second part, and a third part connected in sequence, with the third part connected to the fourth part. The first part, the second part, and the fourth part are all bent, while the third part is planar. Through the application of this utility model, a copper clip structure and copper strip for use in medium-to-high power devices are proposed. It increases the copper clip area to meet the application scenarios of medium-to-high power devices. By employing two pairs of connecting ribs, the problem of insufficient support caused by the large size and concentrated center of gravity of the copper clip is solved. The two pairs of connecting ribs can provide sufficient support for heavy and large-sized copper clips, preventing tilting, twisting, and deformation during transportation and processing, ensuring reliable manufacturability and intact function.
