Abstract
A fuse includes a tubular body having two ends each having a first cap, which is formed with a through hole; a fusible and breakable unit including a first fusible filament arranged inside the tubular body and having two ends extending outward through the through holes respectively; and a plurality of second caps each of which has a surface that is formed with a recessed part and an opposite surface that is provided with a conductive wire. The recessed parts of the second caps are mounted to outer circumferences of the first caps. The two ends of the first fusible filament are respectively coupled between the first caps and the second caps corresponding thereto so as to extend a distance between the two ends of the first fusible filament and thus, preventing the occurrences of electrical arc after the first fusible filament is fused and broken.
Claims3
A fuse, comprising:
- a tubular body, which has two ends each of which is provided with a first cap, each of the first caps being formed with a through hole;
- a fusible and breakable unit, which comprises a first fusible filament and a second fusible filament connected to the first fusible filament, the first fusible filament having a melting point that is lower than a melting point of the second fusible filament, the first fusible filament and the second fusible filament being arranged in an interior of the tubular body, the first fusible filament and the second fusible filament each having an end extending outward through one of the through holes, a third fusible filament arranged to connect between the first fusible filament and the second fusible filament, the melting point of the second fusible filament being lower than a melting point of the third fusible filament;
- and
- a plurality of second caps, each of the second caps having a surface that is formed with a recessed part and an opposite surface that is provided with a conductive wire, the recessed part of each of the second caps being mounted to an outer circumference of a corresponding one of the first caps, the ends of the first fusible filament and the second fusible filament being respectively coupled between the first caps and the second caps corresponding thereto.
