ABSTRACT:
The invention relates to a method for the production of a sub-miniature fuse, as well as to a sub-miniature fuse. Known casing with three chambers and a separate cover are difficult to manufacture and are prone to faults due to their complicated shape. According to the invention, an internally substantially smooth surface and externally cylindrical casing is formed, preferably from identical tube halves, whose end faces are closed either by correspondingly constructed connecting electrodes or by concomitantly shaped end walls, the electrodes always carrying the fuse wire on their inside and the connecting leads on their outside. Preference is given to the use of an intermediate member, which encloses the electrodes and the fuse wire fixed thereto. In each case production is simplified. There is also no need for shrink-on tubes for the insulation of contact caps.
