ABSTRACT:
A continuous hollow compartment open at both opposite ends thereof is arranged within an electrically insulating housing. Tubular portions of end contacts extend into ends of the hollow compartment and are completely covered at their inner surfaces by an arc-inhibiting screen. Flat portions of the end contacts form clamping locations and solder pins. The ends of a fuse wire and the ends of the screen are clamped at the clamping locations. The solder pins form a respective wave solder region and a reflow solder region. During manufacture of the safety fuse element, the tubular-shaped end contacts are inserted into the ends of the hollow compartment of the housing. Then there is drawn-in the screen and the fuse wire and the flattenable portions of the end contacts are flattened to form the flat portions, so that there are clamped at the clamping locations the ends of the fuse wire and the ends of the screen. Now the flat portions are bent to form the solder pins. The safety fuse element can be completely automatically fabricated and completely automatically deployed. Such safety fuse element possesses a considerable inhibiting of electrical arcs with small dimensions and is suitable for use as a surface mount device (SMD).
