ABSTRACT:
A method for assembling fuses having casings closed by plug terminals conductively interconnected by helically wound fusible elements. The fusible elements are wound around squirrel-cage-like structures involving extremely thin and extremely stiff metal rods. These rods are withdrawn from the fusible elements and drawn out of the casings of the fuses at such time when the pulverulent arc-quenching filler filled into the casings provides sufficient support for the fusible elements so that the support thereof previously provided by the aforementioned metal rods can safely be dispensed with. The small diameter of the rods minimizes the voids initially formed by their removal which, in turn, minimizes the tendency of the fusible elements to be somewhat displaced incident to removal of their temporary metallic supporting rods.
A fixture for carrying the assembly process into effect includes means for the fixation of the ends of the supporting rods for the fusible elements that project beyond the plug terminals of the fuses.
