Problems solved by technology

[0003] The ambient temperature that determines the function of the current temperature protector depends on the thermal bending rate of the bimetal sheet used in production, but the current temperature protectors on the market have already determined their working environment temperature when they leave the factory, and there is no setting in the structure Any adjustment mechanism to adjust the temperature protector in use to meet the different requirements of its working temperature value under different circumstances, lacks flexibility. In the current situation, if it is required to change the temperature value of the circuit cut , it is necessary to replace the corresponding current temperature protector

Abstract

The invention discloses a temperature protector which comprises a spring leaf and two housings that are buckled with each other in the vertical direction. The two housings are respectively provided with a lug. One end of the lug is arranged in the housing, and the other end is arranged outside the housing. The contact surfaces of the two housings are respectively provided with one layer of insulating paper, wherein the lug in one housing is fixedly connected with the spring leaf. The spring leaf is provided with a moving contact. A bimetallic plate is fixed on the spring leaf. The lug in the other housing is provided with a static contact which corresponds with the moving contact. The housing above the static contact is in threaded connection with a rotatable insulating debugging member. One end of the rotatable debugging member is arranged in the housing and presses the lug at the static contact, and the other end is arranged outside the housing. The temperature protector has advantages of simple structure, high convenience in mounting, detachment and maintenance, high temperature sensing speed, and quick regulation for a rated temperature.

Description

technical field [0001] The invention relates to the field of electrical protection components, in particular to a temperature protector. Background technique [0002] The existing temperature control switch similar to the temperature protector that is connected in series in the electric equipment circuit is normally closed in the normal working state and disconnected in the over-temperature state through the bimetallic thermal switch element, so as to realize the control function. For the work of electrical equipment, most of the existing protectors use shells and insulating seals. If a fault occurs, the entire protector can only be replaced, and the cost is relatively high. [0003] The ambient temperature that determines the function of the current temperature protector depends on the thermal bending rate of the bimetal sheet used in production, but the current temperature protectors on the market have already determined their working environment temperature when they leav...
