A waterproof temperature sensitive controller

Abstract

The invention relates to the technical field of a temperature controller, specifically a waterproof temperature sensitive controller. The controller comprises a shell of which upper end is opened; a temperature sensing cover is covered on the upper end opening of the shell; two electric terminals are arranged on the base plate of the shell; a tray is fixedly arranged in the upper end opening of the shell; a thermosensitive sheet resisting against the temperature sensing cover is arranged on the upper end surface of the tray; a waterproof structure is arranged between the outer edge of the upper end of the shell and the temperature sensing cover; the lower end of the shell stretches downwards along the base plate and is equipped with a packaging ring; the lower ends of the electric terminals are connected with leads; the leads pass through threading openings and are leaded out transversely; and sealing glue is filled in the inner cavity of the packaging ring. The controller provided by the invention has the advantages that the structure is rational; a sealing structure except the temperature controller body is prevented from being added; a flatted design is realized through adoption of an inverse Y-shaped linkage moment arm and a flexible tongue piece; the tray and the outer edge of the shell match and are assembled integrally; the height of the integral structure can be effectively compressed; the layout is compact; the assembly is convenient; the reaction is sensitive; the assembly efficiency can be improved; and the integral cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of temperature controllers, in particular to a waterproof temperature-sensitive controller. 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. Power-off reset means that after the temperature sensitive element deforms and breaks the dynamic and static contacts, the heating circuit is turned on, so that the temperature sensitive element continues to maintain the deformation state under the contact of the heating element, so that the dynamic and static contacts continue to break, requiring manual intervention. Sensitive components return to their original state. Generally speaking, the power-off reset adopts a short-circuit circuit, that is, the dynamic and static contacts are turned on in the initial state before the temperature-sensitive element of the...

Problems solved by technology

In the existing design, the thermostat body is generally provided with a casing, the lead wires are soldered, fixed and then sealed with resin, resulting in more dimensional extensions on the thermostat body. Therefore, how to compress the design to provide a A reliable and beautifully designed waterproof temperature-sensitive controller product has become an industrial problem that customers and industry companies urgently need to solve.
