Abstract
A novel fuse assembly design utilizes a fuse body, a single-piece terminal assembly and a two-piece endbell. 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.
