The first static contact point for matching of point, the double gold plaques of kick be located at the lower section of the first movement elastic slice and with its companys of offseting, kick is double golden
Piece is contacted with support convex.
Preferably, the first movement elastic slice is fixedly installed the bending part to match with the double gold plaques of kick.
Preferably, elastic plate mechanism include the spring leaf being arranged on insulation assembly and static contact on piece is set it is second quiet
Contact point is fixedly installed the second movement elastic slice on spring leaf, is provided on the second movement elastic slice and the second static contact point matches
The the second movement contact closed, the both ends of porcelain knob are separately connected bimetal leaf and spring leaf.
Preferably, the insulation resistance of insulation assembly is 100M Ohm.
The utility model has the advantages that
When bimetal leaf failure can not deform or elastic plate mechanism failure can not flick, overtemperature protection system temperature is after of continuing rising
The high double gold plaques movement kicks of the kick after reaching preset temperature, since the porcelain bar eliminated in existing overtemperature protection system is set
Meter, and the double gold plaques of kick are located at the lower section of the first movement elastic slice and contact with support convex, therefore the double gold plaques of kick are in its movement
The first movement elastic slice can be pushed directly on when kick, promote the first movement contact and the first static contact point quick separating, therefore shorten
The disengaging time of the two, accelerates the response time of overtemperature protection system, meanwhile, bending part can play the double gold plaques of kick solid
Fixed and stable effect, ensure that the first movement contact and the first static contact point quick separating, therefore overtemperature protection system is effective
Electric heater is protected, prevents electric heater from burning out and even causes fire, temperature controller provided by the utility model is temperature controller and insurance
It is combined into one, reduces the production cost of temperature controller, and easy for installation, it is reliable and stable under hot environment.
