Abstract

The invention provides an ultramicro-fuse and a manufacturing method thereof. In the invention, a first electrode, a conductive part and a second electrode are printed in a fuse circuit; the fuse is arranged in a pipeline, a first metal cap and a second metal cap are covered at two ends of the pipeline respectively; the pipeline, the first metal cap and the second metal cap are covered by an insulating layer; the fuse uses the printed circuits, so that consumption of metal materials can be reduced in manufacture, production cost is reduced, and electric arc can be avoided when the fuse is fused. Therefore, the ultramicro-fuse has the advantages of high yield, high quality and high safety.

Description

Technical field

[0001] The present invention relates to an ultra-miniature fuse and a manufacturing method thereof. It provides a fuse body made by circuit printing to replace the existing fuse, so as to avoid the arc phenomenon that may occur when the fuse is blown, and reduce the metal material Consumption, so that the present invention can achieve high yield, high quality and high safety. Background technique

[0002] When an excessive current flows through the circuit, the circuit will overheat, which will lead to the damage or ignition of the electrical appliance. In order to avoid the aforesaid situation, a fuse will be installed in the circuit. When there is an excessive current, The fuse will fuse inside, so that the circuit becomes open, thereby avoiding electrical damage or fire.

[0003] For example, "Ultra-small high-voltage slow-blow fuse structure and manufacturing method" of Taiwan Invention Patent Application No. 200820296, which discloses a fuse structure, please ...
