ーズ。[Claims for Utility Model Registration] Has an opening at one end and an output lead terminal 4 at the bottom.
A thermosensitive pellet 2 is housed in a cylindrical case 1 with a fixed bottom, and an input lead terminal 5 is inserted into an insulating bushing 3 that is inserted and fixed into the opening of the case 1 and sealed with a sealing resin 6. Insert and fix,
Furthermore, the temperature-sensitive pellet 2 and the insulating bushing 3
A strong compression spring 10 held between the spring guides 8 and 9 and a weak compression spring 11 arranged in series with the movable contact piece 7 sandwiched between the strong compression spring 10 are housed. In a temperature fuse configured such that the movable contact piece 7 contacts the fixed contact 12 of the input lead terminal 5, a retainer 5a is provided on the outer peripheral surface of the input lead terminal 5.
A temperature fuse characterized in that an insulating bushing 3 made of an insulating material is integrally molded and fixed concentrically with the input lead terminal 5 at the position of the retainer 5a.
