ABSTRACT:
A fusible link includes a housing which is made of insulating resin, the housing has an opening through which a fuse element is inserted into the housing, a fuse element having a pair of connecting terminal sections and a fusible body connected between the connecting terminal sections, and a lid of insulating resin which covers the opening of the housing while engaging with the housing. In the fusible link, the lid has resilient protruded pieces which are extended downwardly from the inner surface of the lid, and pressed against the fuse element so that the fused ends of the fuse element are away from each other when the fusible body is fused, thereby to positively prevent the occurrence of secondary short-circuiting of the fused ends.
