Patent JP-H11353992-A (JP)
Title: Thermal protector
Inventor: SHINNO MASAHIKO
IPC: H01H37/54
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a thermal protector without a snap delay. SOLUTION: As shown in (I), a bimetal 40 is fixed to a holding part 40b with a fixing pin 52, while a snap part 40a is supported with a support part 12a. A free end part 40a" of the snap part 40a contacts a moving contact plate 30 so as to swing the moving contact plate 30. Because movement of the snap part 40a is restricted in a boundary end part 40a' by the fixed holding part 40b, the snap part 40a swings like a lever with the support part 12a supporting the snap part 40a as a center, when a snap action (reverse) occurs. That is, because the free end 40a" of the snap part 40a largely moves, a moving contact point 32 can have a long movable distance when the moving contact plate 30 flips. Accordingly, generation of a snap delay is prevented.
