Abstract

A high-fidelity high-temperature-resistant temperature controller relates to the technical field of temperature sensing controller design. The high-fidelity high-temperature-resistant temperature controller comprises a shell with an opening at one end. A ceramic base and a ceramic base sealing cover are arranged in the shell. A static contact piece and a spring piece are arranged between the ceramic base and the ceramic base sealing cover. One side, near the open end of the shell, of the ceramic base is provided with a through hole in which a rivet is arranged. A static contact is arranged above one end, far away from the rivet, of the static contact piece, and a movable contact matched with the static contact is arranged below one end of the spring piece. The middle of the spring piece is provided with a downward bulge, a ceramic top column is arranged below the bulge, and the lower end of the ceramic top column passes through the ceramic base and is connected with a bimetallic strip. The lower end of the rivet is connected with a wiring piece, and the outer end of the wiring piece is connected with a wire. The opening of the shell is sealed with epoxy resin. The high-fidelity high-temperature-resistant temperature controller is simple in structure and easy to realize, has the characteristics of high fidelity, high sensitivity and resistance to high temperature, and is applicable to temperature control and protection on household electric heating appliances and similar electric equipment.

Description

technical field [0001] The invention relates to the technical field of design of temperature sensing controllers. Background technique [0002] There are plastic parts inside similar products on the market, which greatly reduces the sensitivity and followability of the product to the ambient temperature. Temperature lag has become an inevitable defect of most products on the market. Furthermore, the temperature resistance of plastic is not very high, which limits the protection temperature range of the product. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a high-fidelity and high-temperature resistant temperature controller with high fidelity, high sensitivity and high temperature resistance. [0004] The present invention comprises a shell with an open end, in which a ceramic base and a cover of the ceramic base are arranged; between the ceramic base and the cover of the ceramic base, a static contact p...
