Abstract
An electric plug type fuse. The hollow glass body thereof contains a strip-like spring conductively connected to the bottom contact in the insulating tip of the fuse. Said spring is arcuate and has a center of curvature situated at the side of the spring where the longitudinal axis of the glass body is located. A solder joint preferable of a eutectic metal connects the end of the spring remote from the bottom contact to a fusible element capable of interrupting short-circuit-like currents, i.e. a ribbon type fusible element having at least one point of reduced cross-section. The aforementioned spring and the fusible element enclose an angle of approximately 90 deg. and the end of the fusible element remote from said spring is conductively connected to a screw shell. The spring puts the fusible element under tension and is released from it when the solder joint connecting both parts melts.
