Electric plug fuse with corrugated element

An electric plug type fuse including a substantially cylindrical hollow glass body defining a cavity and being screw threaded on the outer surface thereof, a contact button support of an electric insulating material of which one end projects into the cavity and the other end projects away from the cavity to the outside thereof, a contact button on the outer end of the contact button support, a metal shell overlapping the contact button support, the metal shell being screw threaded, and the screw threads thereof mating with the screw threads on the glass body, the glass body having a groove on the outer surface thereof extending perpendicular to and interrupting the screw threads on the glass body, the groove and the metal shell cooperating to define a channel therebetween, a strip-like fusible element having one end thereof conductively connected to the contat button and extending therefrom into the cavity defined by the glass body, the other end of the fusible element extending from the cavity, between the contact button support and the glass body into the channel defined by the groove and the metal shell, where the other end of the fusible element is soldered to the metal shell, wherein the improvement comprises:

• forming said other end of said fusible element which extends into said channel into a geometric shape which defines a plurality of substantially separate longitudinal solder receiving cells in said channel between said fusible element and said metal shell.
