Temperature controller with thermistor

Abstract

A temperature controller with a thermistor comprises a coupler seat body and an installation support, a power connection terminal piece is arranged on the coupler seat body, an insulation sleeve is installed on the installation support, the thermistor is installed in the insulation sleeve, and a lead of the thermistor penetrates out of a port of the insulation sleeve to be connected with the powerconnection terminal piece. According to the structure, the structure of the temperature sensing probe is simplified to the maximum extent, a shell and a metal top cover of a main structure of a traditional probe and an external wire connected with a lead of the thermistor are omitted, the production cost of the temperature sensing probe is greatly reduced, assembling procedures are reduced, and the production efficiency is improved; the assembly process that glue is poured into the metal shell for fixing the thermistor is omitted in the assembly proccess of the temperature sensing robe, and the situation that harmful substances separated out of the glue are inhaled by the human body, and consequently personal injuries are caused to assembly personnel is avoided.

Description

technical field [0001] The invention relates to the field of temperature controllers, in particular to a temperature controller with a thermistor. Background technique [0002] The current temperature probe structure roughly includes a metal shell and a thermistor installed in the metal shell. When the thermistor is installed in the inner cavity of the metal shell, the thermistor is fixed by injecting sealing glue into the inner cavity of the metal shell. In the process of sealant, residual air bubbles in the inner cavity are prone to appear, so that when the temperature sensing probe is heated at high temperature, the air in the bubble is heated and expands, which is prone to safety problems such as explosion of the temperature sensing probe, and the production and assembly process is complicated, and the production efficiency is low. The sealing glue used may release harmful substances and be inhaled by the assembler, causing personal injury. In addition, the raw materials...

[0002] The current temperature probe structure roughly includes a metal shell and a thermistor installed in the metal shell. When the thermistor is installed in the inner cavity of the metal shell, the thermistor is fixed by injecting sealing glue into the inner cavity of the metal shell. In the process of sealant, residual air bubbles in the inner cavity are prone to appear, so that when the temperature sensing probe is heated at high temperature, the air in the bubble is heated and expands, which is prone to safety problems such as explosion of the temperature sensing probe, and the production and assembly process is complicated, and the production efficiency is low. The sealing glue used may release harmful substances and be inhaled by the assembler, causing personal injury. In addition, the raw materials of the metal shell and the top cover are expensive, which increases the production cost of the temperature sensor. During assembly, it is necessary to use external wires to connect the thermistor and the ground Electrical terminal piece connection, increase assembly process, thereby reducing production efficiency
