Description

Technical Field

[0001] The utility model specifically relates to an open temperature protector. Background Art

[0002] The bimetallic temperature switch currently used mainly includes a base, a silver sheet assembly, a bimetallic strip, a moving reed, a moving contact, a shell, etc. The above components are welded into a whole by welding technology. The temperature protector is a closed structure. When working, the bimetallic strip is in a free state, the moving contact and the silver sheet assembly are closed, and the circuit is turned on. When the temperature of the electrical appliance rises to the operating temperature of the temperature protector due to heat generation, the shell is heated and transmitted to the bimetallic strip. The bimetallic strip generates internal stress due to heat and quickly moves, pushing the moving contact away from the silver sheet assembly to disconnect the circuit, thereby cutting off the power supply of the electrical appliance to protect it. When the temperature of the protected electrical appliance drops to the rated reset temperature value of the temperature protector, the bimetallic element returns to the initial state and the contact is closed, and the electrical appliance resumes normal operation. However, the existing bimetallic temperature protector has the following main disadvantages: the bimetallic strip in the existing structure is not directly heated, and the medium is conducted when heated, resulting in heat loss to the bimetallic strip; there is no memory function.

[0003] Improvements have been made to the technical problems existing in the above structure. For example, a patent for this utility model has been published in China.

The structure discloses a base, a first terminal piece is provided on the left side of the base, the right end of the first terminal piece is overlapped on the base and fixed by rivet A, a static spring piece extending to the left is provided on the top of the first terminal piece, and a static contact is provided on the top of the static spring piece; a second terminal piece is provided on the right side of the base, the left end of the second terminal piece is overlapped on the base and fixed by rivet B, a circuit fault memory device is connected between the bottom of rivet B and the bottom of rivet A, a moving spring piece is provided between the left end part of the second terminal piece and the base, a moving contact abutting against the static contact is provided at the bottom of the left end of the moving spring piece, and a bimetallic piece is provided in the cavity formed by the moving spring piece, the static spring piece and the base. However, the way that rivet B and rivet A fix the first terminal piece and the second terminal piece respectively increases the overall production process and reduces the production efficiency.
