Abstract
A tubular shaped high voltage fuse, with a support tube of insulating material, having applied thereon parallel fuse conductors, and an outer tube of insulating material, surrounding the support tube. The end cap consists of a cup-shaped electrically conducting cap to be placed upon the ends of the support tube and the outer tube, a tore-shaped, closed helical contact spring of electrically conducting material to be placed around the support tube end for connecting the fuse conductors with the cap and a spacing piece of insulating material having resilient strips connected therewith for compensating tolerance deviations and for centering, together with the helical spring, the support tube within the outer tube.
