Once-molding adjustable temperature controller

Abstract

The invention discloses a once-molding adjustable temperature controller, which comprises a base, a lug plate, a contact piece, a stationary contact, a moving contact, a mounting bracket, a bimetallic strip, a tip cone, a spring plate, an ejector rod, temperature-adjusting internal threads, a temperature-adjusting rotating shaft and a positioning meson; the base is made of high-temperature resistance plastic materials. The lug plate, the contact piece, the spring plate, a large body piece, the bimetallic strip and a fixing bracket of the once-molding adjustable temperature controller are all fixed on the base by adopting a once injection molding mode, so most of the main body structure of the adjustable temperature controller can be once formed; and a spring plate structure component adopts an integral spring plate, so spare parts and the production process are simplified, the strength safety of the adjustable temperature controller is better guaranteed, the original complex product structure and the production process become simple and practical, the product cost is greatly reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a circuit component, in particular to a one-time molding adjustable temperature controller which realizes circuit on or off according to the temperature. Background technique [0002] At present, many electrical products use thermostats, which control the opening and closing of contacts by sensing the temperature of electrical products, thereby controlling the opening and closing of electrical heating circuits, so as to achieve the control and protection of electrical circuits. The existing adjustable thermostats on the market all adopt the riveting method of socket nails to fix the contact pieces, lugs and body pieces. The porcelain tubes set by the socket nails are used for insulation. When assembling the product, this structure causes high assembly difficulty and many processes, and the production efficiency is very low, and the porcelain ring and porcelain tube are prone to bursting, which poses a great hidden danger to pro...

Problems solved by technology

The existing adjustable thermostats on the market all adopt the riveting method of socket nails to fix the contact pieces, lugs and body pieces. The porcelain tubes set by the socket nails are used for insulation. When assembling the product, this structure causes high assembly difficulty and many processes, and the production efficiency is very low, and the porcelain ring and porcelain tube are prone to bursting, which poses a great hidden danger to the product safety performance. Therefore, it is urgent to solve the above problems.
