Abstract

The invention discloses a contact type bimetallic strip temperature controller. The controller comprises a shell, a bottom plate and a bimetallic strip; the shell is arranged on the bottom plate and is fixedly connected with the bottom plate; a protruding part is arranged in the middle of the shell; the bimetallic strip is fixedly arranged at the top of the convex part; a vertical through hole isformed in the convex part; an ejector rod is inserted into the vertical through hole in a penetrating mode; a first terminal is arranged at one end of the bottom plate; an elastic piece is connected to one end of the first terminal; a first contact and a second contact are arranged on the elastic piece; a second terminal is arranged at the other end of the bottom plate; the second terminal and thefirst terminal are symmetrical; and a third contact is arranged at one end of the second terminal and matched with the second contact in an abutting mode. The controller is small in size and can be applied to small or micro electric appliances.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a contact type bimetal temperature controller. Background technique [0002] Due to its accurate temperature control, excellent electrical performance, simple manufacture, low price and practicality, the bimetal thermostat is widely used in small household appliances, motors, rectifiers and household appliances. Temperature and overheating protection, etc. [0003] The current thermostat usually sets the bimetal inside the shell, and the shell is used to protect the bimetal or other electronic components inside. The working principle of the thermostat is that the external temperature is first transmitted to the shell through the air. , and then transferred from the shell to the air inside the shell, so that the bimetal sheet receives heat, resulting in deformation and displacement, so that the contacts are clutched, so as to achieve the purpose of connecting and disc...
