Claims

[Scope of Claim for Utility Model Registration] (1) A through hole is provided near the center of an electrically insulating and heat resistant chassis made of ceramic or the like, and the upper part of the through hole is covered so that when the temperature reaches a certain level, the A bimetal that operates in reverse is stacked on the shear sheath with its high expansion coefficient side facing the through hole, and an electrical resistance piece is attached to the lower side of the shear sheath and is fused at a temperature above the above-mentioned certain temperature. and a temperature fuse at a curved portion connecting the electric resistance pieces is provided so as to enter into a through hole of the sheath, and the bimetal and the electric resistance pieces are integrally fastened to the shear sheath with rivets via an insulating plate and an insulating pipe. A protector with a temperature fuse featuring (2) The contact surface of the fixed contact provided at one end of the bimetal, which is in constant contact with the movable contact and connected to one end of the temperature fuse, is slightly inclined in the mounting and fixing direction of the bimetal. A protector with a temperature fuse as described in Range 1. (3) The upper terminal connected to the end of the bimetal on the side opposite to the side where the movable contact is provided and the lower terminal connected to the end of the temperature fuse on the side opposite to the side connected to the fixed contact are shear-sealed parallel to each other. A protector with a temperature fuse according to claim 1 or 2 of the utility model registration claim, wherein the protector has a plug-in type connecting portion projecting outward from the protector.
