Abstract

A sealed fuse in accordance with the present disclosure may include a tubular fuse body, a trench formed in an exterior of the fuse body, and an electrically conductive endcap that fits over an end of the fuse body and is fastened to the fuse body by an electrically conductive material having a lip portion that extends into the trench to provide a barrier that extends between the fuse body and the endcap. In an embodiment, the trench may be formed in an end face of the fuse body and may extend entirely around an opening in the end of the fuse body. In another embodiment, the trench may be formed in an outwardly-facing surface of a sidewall of the fuse body and may extend entirely around the fuse body.
