Description

Technical Field

[0001] The utility model relates to the technical field of chip fuse components, and more specifically, to a chip fuse component. Background Art

[0002] In existing electronic technology, SMD fuse assemblies are a common circuit protection component widely used in various electronic devices. However, these traditional fuse assemblies have certain limitations in design. Specifically, they usually cannot adjust the fixed position of the fuse. This means that during installation, the position of the fuse is fixed and cannot be adjusted according to the specific layout and space requirements of the circuit board. This fixed installation method may result in an unsatisfactory distance between the fuse and other electronic components, thus affecting the overall layout and performance of the circuit.

[0003] Furthermore, since the fixed position of the fuse cannot be adjusted, this may affect the protection effect of the circuit. The function of the fuse is to disconnect the current when the circuit is overloaded to prevent the circuit from being damaged. However, if the position of the fuse is not appropriate, it may not be able to disconnect the current in time when the circuit is overloaded, or in some cases, it may mistakenly disconnect the current and cause misprotection. This unadjustable fixed position not only limits the application range of the fuse assembly, but also reduces the protection effect and reliability of the circuit to a certain extent.
