Abstract

The invention discloses a secondary protection temperature controller, and relates to the field of design technologies of temperature sensors and controllers. The secondary protection temperature controller comprises a plastic pedestal, wherein the plastic pedestal is provided with a sealing cover buckle thereon, and the internal part of the plastic pedestal is provided with a spring piece, a bimetallic strip, a guide pillar and a plug plate set; one end of the spring piece is connected with the plastic pedestal through a first rivet, and the lower surface of the other end of the spring piece is provided with a moving contact; the lug plate set comprises a first lug plate, a connecting sheet and a second lug plate; the first plug plate is connected to the plastic pedestal through a first rivet and a second rivet; the connecting sheet is arranged on the plastic pedestal below the spring piece through a third rivet, and a static contact matched with the moving contact is arranged above the third rivet; and the plastic pedestal is further internally provided with a fuse wire. The secondary protection temperature controller disclosed by the invention is simple in structure and easy to realize, and a secondary protection function is realized on a condition that the secondary protection temperature controller has functions of products of the same kind, so that the product safety and the product reliability are substantially improved.

Description

technical field [0001] The invention relates to the technical field of temperature sensor and controller design. 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. Similar products on the market do not have secondary protection functions, and the mechanical structure is easily affected by external forces and fails. Contents of the invention [0003] The object of the present invention is to provide a secondary protection temperature controller with higher security and a secondary protection function to solve the above problems. [0004] The invention comprises a plastic base, on which a cover buckle is arranged, a spring piec...
