Component Structure of Current Protection

Abstract

The invention provides a current protection element structure, which comprises a first substrate, a supporting layer, a circuit layer and a second substrate which are overlapped in turn, wherein one surface of the first substrate relative to the supporting layer is a setting surface; one surface of the second substrate relative to the circuit layer is an adhering surface; the adhering surface is provided with a second recess; and the setting surface is selectively provided with a first recess. Due to the recess, pressure generated by the circuit layer during fusion can be removed at the recess, so that the circuit layer is completely fused to avoid an arc effect; moreover, the structure can be used in light, thin, short and small electrical equipment, market requirements can be met, and an effect of protecting the electrical equipment can be achieved.

Description

technical field [0001] The present invention provides a current protection component structure, which can avoid the generation of arc effect and can be used by light, thin, short and small electrical equipment, so as to meet the needs of the market. Background technique [0002] Most of the existing wire protection wires are composed of two superimposed substrates, and a fuse is interposed between the two substrates, and an electrode is respectively provided on both sides of the two substrates, and the electrodes are electrically connected to the fuse. , the substrate is a solid body. [0003] In an ideal state, when an excessive current passes through the fuse link, the fuse link will be blown, but in reality, the pressure generated by the fuse link when it is blown is limited by the solid substrate and cannot be removed, making the original Some of the fuses that should be blown are still connected, which will cause arc effects, which will make the circuit safety unable t...

Problems solved by technology

[0003] In an ideal state, when an excessive current passes through the fuse link, the fuse link will be blown, but in reality, the pressure generated by the fuse link when it is blown is limited by the solid substrate and cannot be removed, making the original Some of the fuses that should be blown are still connected, which will cause arc effects, which will make the circuit safety unable to be guaranteed, and will cause electrical equipment to be damaged, burned, injured or dangerous accidents, etc.

[0004] Therefore, the existing fuses cannot meet the trend of light, thin, short, and small electrical equipment, and cannot meet the needs of the market
