Problems solved by technology

The key structure of the thermostat lies in the installation of the temperature-sensing element. Its installation and shape design are related to the disconnection accuracy and life of the thermostat. The other is the temperature sensing of the thermostat. Today's thermostats are sealed for safety. They are all packaged in a shell, but this will affect the temperature sensing effect of the temperature sensing element, thus affecting the working accuracy of the thermostat

Abstract

The invention, which belongs to the technical field of temperature controllers, in particular relates to a manufacturing process of an open type temperature controller. The method comprises: step one,a fixed contact piece and a fixed contact are riveted to form a fixed contact assembly; step two, a moving contact piece and a moving contact are riveted to form a moving contact assembly; step three, the fixed contact assembly is fixed to one end of a porcelain base by a first rivet; step four, thermal processing and temperature screening are carried out on a bimetallic strip and then the processed bimetallic strip is fixed at the middle part of the porcelain base; and step five, a wiring piece and the moving contact assembly are fixed at the other end of the porcelain base by a second rivetand the moving contact is abutted against the fixed contact. On the one hand, a temperature sensing element is installed on the surface of the porcelain base and no enclosed shell is added; and the temperature sensing element is used for sensing the temperature, so that the temperature control accuracy and reaction efficiency are improved; and on the other hand, the bimetallic strip overturns todrive the moving contact at the moving contact piece and the fixed contact on the fixed contact piece to be separated or closed, thereby realizing circuit disconnection or connection. Moreover, the manufacturing process is simple; and the operation is simple and convenient. The manufacturing process is suitable for large-scale production of the enterprise.

Description

technical field [0001] The invention belongs to the technical field of temperature controllers, in particular to a manufacturing process of an open temperature controller. Background technique [0002] The working principle of the thermostat is that the bimetal sheet is bent upward after being heated, pushing the contact of the shrapnel to open, thus playing the role of temperature control, that is, the temperature control accuracy of the thermostat is determined by the bending rate and deformation range of the bimetal sheet. Most thermostats are used in electric tools such as motors and ballasts. With the increasingly sophisticated and compact designs of these tools, the structure of thermostats is also designed to be smaller and smaller. Due to their small size, micro thermostats are not only easy to install It can also be installed on the desired product by inlaying in narrow places. The key structure of the thermostat lies in the installation of the temperature-sensing ...
