Fuse with secondary short-circuit prevention mechanism

摘要

There is disclosed a fuse with a secondary short-circuit prevention mechanism in which a melting portion, when melted, will not be brought into an unstably supported-condition, thereby positively preventing the melting portion from being again short-circuited. A fuse element 23 includes a pair of parallel terminal portions 29 and 29 interconnected by a connecting portion 31, and a fusible portion 33 is formed at the connecting portion 31. A housing 25 includes terminal receiving chambers for respectively receiving the terminal portions 29 and 29, and a fuse element receiving space for receiving the connecting portion 31, the terminal receiving chambers communicating with the fuse element receiving space. Fixing means 47 and 63 for fixing opposite ends of the connecting portion 31 to an inner surface of the fuse element receiving space 53 are provided at the opposite ends of the connecting portion 31 and the inner surface of the fuse element receiving space, and the fusible portion 33 is provided between the opposite ends of the connecting portion 31.
