FUSE ELEMENT HAVING DAMPING STRUCTURE
A fuse element having a damping structure is disclosed. The fuse element includes a fuse body having two ends, a housing for encapsulating the fuse body and two extending anchor sections connected to the two ends. A meltable portion is coupled between the two ends and housed by the housing, so that the metable portion, when melted, will not contaminate the surrounding space. At least one of the anchor sections has at least one flexible conductive portion. If the fuse element is mounted in a circuit and subjected to shock and vibration, the flexible conductive portion will absorb the mechanical stresses placed on the terminals and the fuse body. As a result, the safety and reliability of the fuse element and the apparatus to which it is connected is significantly enhanced.
