[0002] Fuse links are used for short-circuit protection in rectifiers and related equipment (including inverters and soft starters), semiconductor components, and the complete equipment they comprise. Currently, common fuse links for semiconductor equipment protection typically consist of a tube filled with quartz sand, several fuses within the tube, and contact plates (blades) at each end. Due to the thermal effect of the current, the tube rapidly heats the element, causing the local temperature to rise rapidly until the fuse melts, interrupting the circuit.

[0003] However, the conductor of the photovoltaic fuse in the prior art is an integrated structure, and the conductor is easily oxidized in the air due to the increase in usage time, thereby reducing the effectiveness of the fuse. The conductor cannot be rotated to change the angle, resulting in an unsatisfactory connection effect of the fuse. Summary of the Invention
