Abstract:

A method of assembly of an open-cavity, wire-in-air fuse which provides improved manufacturing yield and fuse reliability, involving coiling, braiding or twisting a fusible element around a sacrificial member during the manufacturing process to provide support for the fusible element to prevent mechanical breakages and necking problems commonly encountered during manufacture.
