Abstract: A method for manufacturing a subminiature fuse includes the steps of applying metallized coatings to surfaces at axially opposite ends of a hollow fuse body, placing a fuse element in an internal cavity in the fuse body, the fuse element extending from the first end to the second end of the cavity, placing a one of a solder and brazing preform and end termination at each of the first and second ends of the cavity, and heating the assembled fuse body, fuse element, solder preforms and end terminations to a temperature sufficient to cause the solder preforms to bond the fuse element to the end terminations and for the end terminations to bond with the metallized end portions of the fuse body, wherein the end terminations close the ends of the cavity. A subminiature fuse according to the invention includes a fuse body with a fuse element disposed in the body. The fuse body includes metallized end portions to which the end terminations are bonded. One of a solder and brazing preform bond the fuse element to the end terminations.

Abstract: In an exemplary embodiment, a fuse body includes a first end, a second end and a bore extending therethrough for receiving a fuse element assembly. The bore includes a clearing portion having a first cross sectional area and a positioning portion having a second cross sectional area. The first cross sectional area is larger than the second cross sectional area. The positioning portion provides a receptacle for receiving the fuse element assembly and ensuring that the fuse element is substantially centered within the clearance portion.

Abstract: The improved fuse assembly includes a trigger assembly having an electrically nonconductive barrel for receiving a spring loaded trigger therein and a heater strip disposed along the outer circumferential surface of the barrel with a pair of end flaps. One end flap has a hole therethrough which fits over the end of the trigger adjacent the short circuit element. A second flap fits over the end of the barrel adjacent the end ferrule. The short circuit element, which is electrically and mechanically linked to a ferrule on the opposite end of the tube from the trigger assembly, engages the trigger and heater element in a solder fusing alloy.
