AI Technical Summary

Technical Problem

In the existing MOS tube fixing structure, the metal shrapnel directly contacts the MOS tube, resulting in the MOS tube being crushed.

Method used

A positioning seat for a MOS tube fixing structure is designed, including an upwardly extending spacer. The spacer is located between the extensions of the positioning seat, forming a positioning groove to position the MOS tube, and ensuring the fixed position of the positioning seat through the coordination of the positioning projection and the positioning hole.

Benefits of technology

Through the design of the isolation sheet, the metal shrapnel is avoided from contacting directly with the MOS tube, sharing the direct pressure of the metal shrapnel on the MOS tube, and avoiding the MOS tube being crushed.

Abstract

The utility model relates to a positioning seat for a metal oxide semiconductor (MOS) tube fixing structure. A positioning seat for an MOS tube fixing structure comprises a positioning seat body, the positioning seat body is provided with a plurality of extending parts which extend upwards and are arranged side by side, the same side of the positioning seat body is provided with isolation sheets which extend upwards, and each isolation sheet is located between two adjacent extending parts. A positioning groove with a lateral opening and an upward opening is formed between every two adjacent extending parts and the corresponding isolation piece, and positioning holes and positioning protrusions which are matched with each other and extend into the positioning holes are arranged between the lower end of the positioning base body and the fixing part. The utility model has the advantages that the metal elastic sheet can be prevented from being directly contacted with the MOS tube, the direct pressure of the metal elastic sheet on the MOS tube can be shared, and the MOS tube is prevented from being crushed by the metal elastic sheet.
