<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a cylindrical current fuse in which a fusible wire is stretched obliquely in a through hole of a ceramic cylinder even if a corner exists at the inner edge of the through hole on the end face of the ceramic cylinder, and the end of the wire can be fixed to the end face of the cylinder while imparting a tension to the wire. <P>SOLUTION: In a manufacturing method of a cylindrical current in which a fusible wire 16 is stretched obliquely in a through hole 12 within a ceramic cylinder 11, when the wire 16 is fixed through the through hole 12, a solder 15 is formed at an edge of the through hole 12 on both end faces of the cylinder 11. When the wire 16 is fixed through the through hole 12, the wire 16 is pulled along the end face of the cylinder 11, a solder is heated and welded to the solder 15 on the end face of the cylinder 11 and, at the same time, the wire 16 is broken. <P>COPYRIGHT: (C)2013,JPO&INPIT |
