Fuses, particularly subminiature cartridge fuses, and a method of manufacture therefor.

摘要

A subminiature fuse comprises a fuse element (1) disposed within a glass sleeve (2) and connected at opposite ends to tail wires (3) which are formed with collars (4) fusion bonded to the wires (3). The collars are positioned within opposite ends of the sleeve (2) which are fused about the collars (4) to effect hermetic sealing. The collars may be glass beads disposed about the wires (4) or they may be of metal suitably having a coefficient of expansion matching that of the glass sleeve (2).
