ABSTRACT:
A metallic terminator member is mounted at each end of a support member for a fusible element of a high-voltage fuse. Each terminator member has a serrated tab projecting into the normal path of the fusible element so that the fusible element can be easily welded to the serrated tab without being distorted and at reduced welding temperatures to avoid damage to the fusible element. The terminator members also have positioning fingers that position the terminator member within the fuse housing and a tab for attaching the terminator member to the end ferrules of the fuse. The terminator members also include a center keyed opening that receives the support member and positions and retains the support member. A wire retainer can be used to engage grooves in the ends of the support member that extend through the keyed opening to lock the terminator member to the support member.
