Title:
ヒューズ
Document Type and Number:
Japanese Patent JP4175844
Kind Code:
B2
Abstract:
A fuse that can be made small while improving its breaking performance. An element 3 is securely held between the two lengthwise ends of a tubular fuse casing 2 and a pair of metal plates 4 having a melting point of more than 1000° C. The ends of the fuse casing 5 are respectively pushed into caps 5 so that the caps are fitted to the fuse casing 2 in such a manner as to cover the metal plates 4. The metal plates 4 protect the caps 5 from direct exposure to an arc discharge, which occurs when the element 3 fuses due to an overcurrent. Even if the fuse casing is made small, the metal plates 4 reliably interrupt overcurrent by absorbing the energy of an arc discharge.
