Abstract
Within an electrically insulating housing there is provided a continuous hollow space open at both ends. Tubular portions of end contacts are insertably disposed at both ends of the hollow space. Flat portions of the end contacts form clamping locations for a fusible conductor and also solder legs. At the clamping locations there are clamped the ends of the fusible conductor. Each of the solder legs form an associated wave soldering region and a reflow soldering region. During fabrication of the fuse device the end contacts which then still possess a tubular-shaped configuration are inserted into the ends of the hollow space of the electrically insulating housing. There is then drawn-in the fusible conductor and predetermined portions of each of the end contacts are pressed flat for form the flat portions. In this way, the ends of the fusible conductor are clamped at the clamping locations. Thereafter, the flat portions are bent to form the solder legs. The fuse device can be completely automatically fabricated and completely automatically used. The fuse device possesses extremely great operability with smallest dimensions thereof.
