Claims

[Scope of utility model registration request]

It has a double inner and outer fuse tube, with an inner tube made of porcelain or glass and an outer tube made of polycarbonate, resin, etc.
In a sealed electric wire fuse, in which terminal fittings for connecting electric wires are protruded from openings at both ends of the outer cylinder, the openings at both ends are sealed with caps, and a fusible material is connected between these terminals in the inner cylinder, the cap is used as the inner cap. Double structure with outer cap,
Terminal fittings with irregularly shaped rotation prevention parts formed on their inner ends are fitted into corresponding holes in the inner cap to connect them in a non-rotating state, and are fixed and integrated by a holding plate. The fitting part shaped to correspond to the non-circular protrusion provided on the outer surface is fitted in a non-rotatable state, and the openings at both ends of the outer cylinder are sealed with inner and outer caps, and the entire outer peripheral surface of the inner cylinder or A closed type electric wire fuse that is partially coated with an elastic covering layer made of rubber or synthetic resin.
