AI Technical Summary

Technical Problem

When the existing fuse lower bracket blows, the fusible element is prone to detaching from the mounting hole due to vibration, causing inconvenience to the staff.

Method used

Limiting blocks, arc surfaces, and inclined surfaces are installed on the wall of the mounting hole. The limiting blocks abut against the molten material, and the arc surfaces and inclined surfaces guide and buffer the molten material from detaching, thereby enhancing the fixing effect.

Benefits of technology

It effectively reduces the possibility of the fuse carrier detaching from the mounting hole, improves the stability of the fuse carrier and the reliability of the fuse lower bracket, and extends the service life.

Abstract

The application relates to the technical field of fuses, and discloses a lower support of a fuse, which comprises a shell, the shell is provided with a mounting hole for inserting a fuse carrying piece, the mounting hole is penetrated in the direction of inserting the fuse carrying piece, a limiting block is arranged on the hole wall of the mounting hole, the limiting block is in abutment with the fuse carrying piece, and the limiting block is located on the moving path of the fuse carrying piece from the mounting hole. The limiting block is in abutment with the fuse carrying piece, so that the limiting block can block the fuse carrying piece from the mounting hole, the limiting block can play a buffering role on the fuse carrying piece, the fuse carrying piece can be reset after being subjected to a force, the fuse carrying piece is more firmly fixed in the mounting hole, and the possibility of the fuse carrying piece being separated from the mounting hole due to vibration of the fuse is reduced.
