Abstract:
1. A method of manufacturing an automobile fuse which changes color upon short-circuiting, comprising: mixing 96˜99 wt % of colored plastic powder with 1˜4 wt % of transparent irreversible thermochromic pigment powder thus preparing a material mixture for a fuse body; melting the material mixture using an injection molding machine so that the fuse body containing a thermochromic pigment component is molded at an injection temperature of 300˜310° C. and an injection pressure of 1200˜1600 kg f/cm drying the fuse body containing the thermochromic pigment component at 100˜200° C. for 3˜5 hr so that a moisture content of the fuse body is decreased to 0.1 wt % or less; inserting a fuse element comprising a pair of terminal members and a fuse member fixed therebetween into a pair of terminal insertion recesses and a fuse charging recess of the fuse body containing the thermochromic pigment component so as to be coupled thereto, thus assembling a fuse.
