Abstract

A lightweight industrial fuse has a housing and a conductive fuse. The housing has a first plastic half-housing and a second half-housing combined with each other. The conductive fuse is integrally formed and clamped between the first and second half-housing. The conductive fuse has a fusible body and two intermediary portions disposed within the housing, and two electrode portions exposed from two opposite ends of the housing. Thus, an enclosed accommodation cavity of the housing is defined through the combination of the first and second half-housing. A manufacturing process is simplified, and a manufacturing cost is decreased, and further a weight of the industrial fuse is effectively reduced.
