    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: Provided herein are protection devices, such as fuses. In some embodiments, a fuse may include a hollow body having first and second ends, each of the first and second ends having an end surface and a side surface extending from the end surface. The fuse may further include a fusible element disposed within a central cavity of the hollow body, the fusible element extending between the first and second ends. The fuse may further include an inner cap formed over at least one of the first and second ends. The inner cap may include a center portion in contact with the fusible element, and a plurality of spring legs extending from the center portion, wherein the plurality of spring legs is in contact with the side surface of the first and/or second ends. The fuse may further include endcaps surrounding the first and second ends.

    Abstract: Approaches herein provide a multiple element fuse including a first fuse element having a first pair of terminals joined by a first fusible link, and a second fuse element including a second pair of terminals joined by a second fusible link. The first pair of terminals may be directly physically coupled with the second pair of terminals. In some embodiments, the first pair of terminals and the second pair of terminals are stacked relative to one another and joined by one or more linking elements, thus causing the first fusible link and the second fusible link to extend parallel to one another. In some embodiments, a first plurality of terminal pairs are integrally linked adjacent one another along a same plane, and then subsequently coupled to a second plurality of terminal pairs.
