Abstract
An improved fuse having one or more counter bores in an interior wall of a hollow tube used as the fuse housing. The fuse includes a fusible element disposed within a cavity defined by the interior wall. The fusible element is electrically connected to first and second end caps via solder. The first and second end caps are attached to respective ends of the hollow tube. The one or more counter bores provide more space for the solder to cover the fusible element resulting in a more reliable electrical connection.
