Abstract
The invention is predicated on the use of synthetic resins as materials for fuse casings or fuse tubes because synthetic resins are relatively easily deformable. This invention is particularly applicable in connection with fuse tubes made of polyester resin and glass fibers. Such tubes lend themselves to making solderless fuse terminals, i.e. electrically conductive joints between the ferrules, or fuse caps, and the fusible element, or elements, inside the fuse tube. The fusible element is located inside the casing or fuse tube and bent over the rim thereof, and has a portion that engages the outer surface of the casing. A ferrule is mounted on the casing and has an indentation in registry with the portion of the fusible element on the outer surface of the aforementioned casing, said indentation engaging and deforming said portion of the fusible element on the outer surface of said casing and exerting a pressure against the aforementioned portion of the fusible element sufficient to establish a conductive, solderless pressure connection between the aforementioned portion of said fusible element and the said ferrule. A portion of the ferrule, or fuse cap, provides a backup for the solderless joint.
