Description

  The present invention relates to a fuse, and more particularly to a fuse assembly structure that displays power interruption by a light emitting function.

Fuses widely used on electrical products or circuits are a type of overcurrent protection device. When a general electrical product fails or an abnormality occurs in its circuit, the current rises momentarily, and if the current rises to the limit at which the fuse can be loaded due to excess current, the fusible material in the fuse will melt and become excessive. It prevents current from flowing to other electronic components inside the electrical product and breaks it, protects the electrical product, and provides a circuit inspection function.

In addition, there is a device for determining whether or not a light emitting component is broken in a fuse so as to be convenient for inspection work. Utility models such as “Safety power cut-off terminal device with light emission instruction” (see Patent Document 1) and “Fuse device with power cut warning effect” (see Patent Document 2) use bipolar light emitting diodes in SMD packages. To achieve a light emission instruction or warning action.
