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.

摘要： In order to prevent erroneous operation caused by shrinking of a thermal pellet due to sublimation or softening of the thermal pellet when current is applied, a thermal pellet type thermal fuse includes a metal casing, a first lead and a second lead leading out from the metal casing, a movable electrode, a thermal pellet, a strong compression spring, and a weak compression spring. Difference in temperature is achieved at the surface of the metal casing by selecting different diameters or wires for the first lead and the second lead, or by providing a heat-radiating plate.

摘要： A thermal fuse includes a metallic casing, a first lead member having a first electrode formed at an end thereof, a second lead member having a second electrode formed at an internal wall surface of the casing, a switching function member including a spring member pressing a thermosensitive pellet and a movable conductor. At an operating temperature as the thermosensitive pellet softens and melts, the thermal fuse switches an electrical circuit between the first and second electrodes. In order to respond and switch more quickly at the operating temperature, the thermosensitive pellet is produced to have a structure that facilitates activation thereof at the operating temperature. Such a structure may involve at least one cavity incorporated in the pellet, or may involve at least two different resin materials that are mixed together or provided in plural layers in the pellet.
