Abstract

The invention relates to a quartz sand fuse. The quartz sand fuse comprises an insulation pipe, a first end cover, a second end cover, a first wiring terminal, a second wiring terminal and a fuse body, wherein a cavity is formed in the insulation pipe and axially passes through the insulation pipe, the first end cover is fixedly connected with one end of the insulation pipe, the second end cover is fixedly connected with the other end of the insulation pipe, the first wiring terminal is fixedly connected with the first end cover, the second wiring terminal is fixedly connected with the second end cover, the fuse body is arranged in the cavity, the first wiring terminal and the second wiring terminal are separately and electrically connected with the fuse body, the interior of the insulation pipe is filled with a quartz sand composition, the quartz sand composition wraps the fuse body, and at least one through hole is formed in the pipe wall of the insulation pipe and is communicated with the cavity. The quartz sand fuse has the advantages of high breaking capability, high explosion prevention performance, good stability and high reliability.

Description

technical field [0001] The invention relates to the technical field of electrical components, in particular to a quartz sand fuse and a manufacturing method thereof. Background technique [0002] The fuse is composed of an insulating tube, a first pole lug, a second pole lug and a melt. The first pole lug and the second pole lug are respectively arranged at both ends of the fuse, and the melt is arranged inside the fuse. The first pole lug The lug and the second pole lug are respectively electrically connected to the melt. [0003] The existing fuses have poor breaking capacity, poor explosion-proof performance and poor stability, so there is a need for improvement. Contents of the invention [0004] The present invention provides a quartz sand fuse and a manufacturing method thereof in order to overcome the above-mentioned defects. The quartz sand fuse has good breaking capacity, good explosion-proof performance, good stability and high reliability; the manufacturing met...
