A Compression Type High Current Temperature Controller

Abstract

The present invention relates to the field of the temperature controller technology, especially to a condensed high-current temperature controller. The controller comprises a housing with an upper end having an opening, the upper cover of the upper end port of the housing is provided with a temperature sensing cover, two wiring terminals pass through on the lower bottom plate of the housing; the housing is internally provided with a temperature sensitive piece, a linkage moment arm and a tongue capable of elasticity extension, and the temperature sensitive piece is fixedly arranged in the upper end port of the housing; the linkage moment arm is transversely arranged and has a fixed arrangement end which is hinged with the housing, the fixed arrangement end of the tongue is in matching connection with the housing, and the extension end of the tongue is connected with the linkage moment arm and is arranged in a herringbone-shaped structure; and the two sides of the fixed arrangement end of the tongue are both provided with motion arms, and the movable end of the two motion arms are in on-off matching arrangement with the two wiring terminals. The condensed high-current temperature controller is reasonable in structure, simplified in the number of the temperature controller structures and effective in the compression of the height of the whole structure through the herringbone-shaped arrangement of the linkage moment arm and the elastic tongue cooperation motion mechanism; and moreover, the condensed high-current temperature controller is compact in layout, convenient to assemble, sensitive in reaction and stable in work in the high-current work condition, etc.

Description

technical field [0001] The invention relates to the technical field of thermostats, in particular to a compression type high-current thermostat. Background technique [0002] The thermostat is a temperature-sensitive controller with automatic action protection, permanent disconnection without power failure, and self-reset function after power failure. It has a wide range of applications and flexible use, especially in various household appliances, which can protect the safety of electrical circuits and avoid damage caused by excessive operating temperatures. Temperature-sensitive controllers need to solve problems such as temperature rise and heat generation, high resistance, and electric strength under the condition of excessive current. Therefore, the internal temperature-sensing sheet and circuit breaker mechanism need to have enough accommodation space, such as the DC temperature-sensitive controller used in automobiles. The overcurrent in the high-power water heater te...

AI Technical Summary

Problems solved by technology

Temperature-sensitive controllers need to solve problems such as temperature rise and heat generation, large resistance, and electric strength under the condition of excessive current. Therefore, the internal temperature-sensing sheet and circuit breaker mechanism need to have enough accommodation space, such as the DC temperature-sensitive controller used in automobiles. The overcurrent in the water heater reaches 35A, and the overcurrent in the temperature sensitive controller of the high-power water heater reaches 40A. Due to the needs of product installation and modeling design, there is an urgent need for a smaller temperature sensitive controller solution. Therefore, how to compress the design to provide A reliable and beautifully designed temperature-sensitive controller product has become an urgent industrial problem that customers and industry companies need to solve
