Thin protection element

Abstract

Disclosed is a thin protection element having at least two electrodes provided installed on an insulating substrate and provide for electrically connecting an external circuit, a fuse structure electrically coupled between the at least two electrodes and provided for fusing at a predetermined temperature, and a shielding structure for at least shielding the fuse structure. The shielding structure is made of an insulating thermoplastic material and directly coated onto a surface of the fuse structure by a film formation technology, and deformable to cope with the protrusion of the melted fuse structure to prevent the fuse structure from being ruined or damaged by the protrusion of the fuse structure. The invention can reduce the total volume of the protection element and facilitate the development of thin products effectively.
