A temperature-sensitive pellet 2 is housed in a bottomed cylindrical case 1 having an opening at one end and an output lead terminal 4 fixed to the bottom; An input lead terminal 5 having a collar 13 on an insulating bushing 3 which is inserted and fixed into the section and sealed with a sealing resin 6.
is inserted through the temperature-sensitive pellet 2 and the insulating bushing 3, and the strong compression spring 10 is held between the spring guides 8 and 9, and the movable contact piece 7 is sandwiched between the strong compression spring 10 and the strong compression spring 10. In the temperature fuse configured such that the movable contact piece 7 is in contact with the fixed contact 12 of the input lead terminal 5, the input lead terminal 5 inserted through the insulating bushing 3 is A temperature fuse characterized in that a locking ring 15 is fitted and a plurality of protrusions 14 are formed on the outer peripheral surface of the input lead terminal 5 to fix the insulating bushing 3 and the input lead terminal 5. 2 A temperature-sensitive pellet 2 is stored in a bottomed cylindrical case 1 having an opening at one end and an output lead terminal 4 fixed at the bottom, while a thermosensitive pellet 2 is inserted into the opening of the case 1 and sealed with a sealing resin. An input lead terminal 5 having a collar 13 is inserted through the insulating bushing 3 sealed by the insulating bushing 6, and a strong compression spring 10 is inserted between the temperature-sensitive pellet 2 and the insulating bushing 3 and held by the spring guides 8 and 9. A weak compression spring 1 is arranged in series with a movable contact piece 7 interposed between the strong compression spring 10 and the strong compression spring 10.
In the temperature fuse configured such that the movable contact piece 7 contacts the fixed contact 12 of the input lead terminal 5, a fixing groove 16 is formed on the outer periphery of the input lead terminal 5 inserted through the insulating bushing 3. A temperature fuse characterized in that a fixing ring 17 is fitted into this, the fixing ring 17 is deformed under pressure, and is engaged with the fixing groove 16 to fix the insulating bushing 3 and the input lead terminal 5.
