A thermosensitive pellet 2 is housed on the output side of the case 1, and an insulating bushing 3 is housed on the input side of the case 1, which has a cylindrical shape.The lead terminal 4 is crimped to the bottom of the case 1, and the lead terminal 5 is inserted through the opening. The insulating bushing 3 is inserted inward, and the opening is sealed with a sealing resin 6.
Furthermore, a movable contact piece 7 is connected between the temperature-sensitive pellet 2 and the insulating bushing 3 by a pressing plate 8 on the output side.
, 9, and a weak compression spring 11 on the input side, the temperature fuse is housed so as to be in contact with the fixed contact 12 provided at the tip of the lead terminal 5, parallel to the strong compression spring 10. Using a coil spring,
A temperature fuse characterized in that the outer diameter of the coil at both ends of a strong compression spring 10 is reduced by 1/2 of the wire diameter during the last turn.
