  • Method of making current limiting fuse having a filter disposed in one end cap
    Patent number: 4003129
    Abstract: The fuse is of the type including an electrically insulating cartridge, a pair of electrically conductive terminal caps at opposite ends of the cartridge, a fusible element within the cartridge in electrical contact with the terminals, and a self-supporting bound matrix filler of arc-quenching particulate matter. The improvement comprises that one of the terminal end caps has a filter disposed on its inside end surface over a drain port.Also disclosed is a method of manufacturing a fuse. The method comprises the steps of assembling the components, packing with arc-quenching particulate matter, filling with a suspension of colloidal silica, removing excess suspension, and drying. In filling, the colloidal silica suspension is forced into a fill port in one end cap and released through a drain port in the other end cap. Before passing out through a drain port in the other end cap, the suspension passes through a filter disposed on the inside end surface of the end cap and overlapping the drain opening.
