ABSTRACT:
An improved electrical fuse having axial leads and comprising a fuse wire in a cylindrical sleeve supported at its ends by lead carrying end caps is coated over the length of the fuse body by an adherent insulating layer (FIG. 4). Improved humidity resistance and mechanical strength are achieved. The necessity for plating the end caps to achieve corrosion resistance is eliminated. Control of coating thickness produces a substantially moderated profile and facilitates application of color coding bands to the coated fuse.
