摘要： A thermal fuse employing a thermosensitive pellet is provided, which exhibits stabilized characteristics in a low operating temperature region. The thermal fuse includes at least a switching movable member, a thermosensitive pellet member, a pair of leads having a first lead portion and a second lead portion, and a metal casing. The thermosensitive pellet member contains a polyolefin wax. The thermosensitive pellet member is housed in the metal casing to which the pair of leads are attached. The switching movable member is operated by deformation associated with softening or melting of the thermosensitive pellet member, to attain a cut-off state between the pair of leads. The thermal fuse employing a thermosensitive pellet is suitable for an operating temperature of 50 to 180° C. Furthermore, in the thermosensitive pellet member the polyolefin wax is mixed with a thermoplastic resin as appropriate, to thereby provide a thermal fuse employing a thermosensitive pellet which increases the response speed while maintaining the operating temperature with high accuracy.

To achieve this, the thermal fuse employing the thermosensitive pellet includes a switching function member including a thermosensitive pellet, a movable conductor, and a spring member.

摘要： A thermal fuse incorporating a thermal pellet has its operating temperature, or heat distortion temperature, adjusted and the thermosensitive material of the pellet avoids deformation, modification or similar deficiency if it is exposed to a severe external environment. The inexpensive thermal fuse provides a wider range from which an operating temperature can be selected, improved insulation resistance after operation, faster response speed in operation, and enhanced strength of the thermal pellet. The thermosensitive material is formed of a thermoplastic resin corresponding to a high molecular weight substance. The thermal pellet's heat distortion temperature is adjusted by a temperature setting method. An enclosure of the fuse has a metal casing with a spring member's strong and weak compression springs both accommodated therein and hermetically sealed.
