Abstract
A slowly-breaking fuse includes a housing made of a synthetic resin, a fuse element including a pair of terminal members for an electrical connection, and a melting member mounted between the terminal members, the melting member being smaller in thickness than the terminal member, the melting member having a narrow elongated central portion and a pair of base portions between which the narrow elongated central portion is mounted, and a cross-sectional area increased member provided at an opposite end of the melting member.
Claims1
A method of producing a slowly-breaking fuse comprising the steps of:
- integrally forming a melting member of a narrow width, provided at a central portion of a fusible member of electrically-conductive metal, with a pair of terminal member;
- integrally forming a pair of retaining means adjacent to opposite ends of the melting member, respectively;
- retaining a low-melting member by the retaining means, which low-melting member is lower in melting point than the electrically-conductive metal;
- and
- subsequently heating the low-melting member to once melt to gather the molten low-melting member around the retaining means;
- and
- subsequently cooling the molten low-melting member to solidify the molten low-melting member to form a pair of cross-sectional area-increased members adjacent to the opposite ends of the melting member, respectively.
