Abstract: A novel fuse assembly design utilizes a fuse body, single-piece terminal assembly and a two-piece endbells. The terminal assembly is disposed within the fuse body and includes first and second opposing surfaces with a fuse element extending between a first terminal and a second terminal. The endbell, to be connected to the fuse body, includes first and second endbell portions. Formed within the first endbell portion is a first receptacle and extending from the first endbell portion is a first protrusion. Formed within the second endbell portion is a second receptacle and extending from the second endbell portion is a second protrusion. When the two endbell portions are fastened to one another with the terminal assembly sandwiched between them, the first protrusion engages the second receptacle and the second protrusion engages the first receptacle.

Abstract: A sub-structure element support system is disclosed. The sub-structure element support system includes a novel molded structure designed to support an electrical element, such as a fuse. The molded structure is a protective and insulative sleeve for the electrical element and reduces forces on the electrical element during free-fall and operation conditions. The molded structure also facilitates automation during manufacturing and reduces cost.

Abstract: A fuse element includes a bridge assembly located adjacent one side of a center portion. The bridge assembly includes multiple bridges connected to a fuse terminal. Each bridge has a cross-sectional area different from each other bridge. A first bridge is adjacent the center portion and has a first cross-sectional area. A last bridge is adjacent the fuse terminal and has a second cross-sectional area greater than the first cross-sectional area.

Abstract: A novel fuse assembly design utilizes single-piece terminal assemblies and two-piece endbells. The two-piece endbells and terminal assembly feature mating elements that enable fastening of the endbell portions to the terminal assembly without use of adhesives. The mating elements also provide positioning guidance for ease of assembly. Slots in the endbells for receipt of insertion pins enable the endbells to be pre-cast/pre-molded without costly rework of molding tools.
