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.

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.

To achieve this, the thermal fuse includes a switching function member including a thermosensitive pellet, a movable conductor, and a spring member. At a prescribed operating temperature the thermosensitive pellet softens or melts to liberate the spring member from a load to cause the spring member to move the movable conductor to switch an electrical circuit located between first and second lead members. The thermosensitive pellet is formed of a thermosensitive material selected depending on a characteristic in flowability presented as it softens or melts.
