ABSTRACT:
The invention relates to a fuse structure, which includes a non-conductive tube connecting both ends with two respective metal caps and an inner resistance filament being inside.

Hence, tin for welding the cap with the tube can prevent from being extruded outside that provides fuse to be flawless and utility.
