Novel PPTC resettable fuse

The utility model provides a novel PPTC resettable fuse, comprising a PPTC device (1) formed by welding and packaging a PTC chip and a novel electrode, and a lead-out pin, one end of the lead-out pin is installed on the PPTC device (1), and the other end of the lead-out pin is successively provided with a first bending part (20), a second bending part (21) and a third bending part (22). Compared with a traditional resettable fuse, the PPTC resettable fuse provided by the utility model has the beneficial effects that the PPTC resettable fuse provided by the utility model can be produced in an automatic, one-step forming and large-scale manner, so that an equipment design engineer does not consider the problem of space height too much during design and model selection and does not consider the influence of welding on a PPTC device too much, and the production efficiency of the PPTC resettable fuse is improved. And the design and production efficiency of engineers is improved. 本实用新型提供了一种新型PPTC自恢复保险丝，包括PTC芯片与新型电极
