Problems solved by technology

[0003] The high-current bimetallic thermostats currently used in the market have large contact resistance, are unstable, and the resistance value is prone to change; and the production process is complicated, and the contact riveting process is manually operated, and the speed is slow; figure 1 and figure 2 As shown, the contacts on the metal shrapnel components are riveted, and the riveting state is not easy to control. There is a gap between the contact and the substrate in the riveting process, resulting in unstable contact and resistance; Printing, affect contact, and the cost is higher

Abstract

The invention discloses a low-resistance bimetal temperature controller. The low-resistance bimetal temperature controller comprises a shell, an end cover, a base and a metal elastic sheet assembly, the shell covers one end of the base, the end cover covers the other end of the base, the metal elastic piece assembly comprises a static piece and an elastic piece, one end of the static piece is provided with a static piece contact, the other end of the static piece is fixed to the bottom of the base, one end of the elastic piece is provided with an elastic piece contact, the other end of the elastic piece is fixed to the bottom of the base, an ejector rod is fixed to the base, and the ejector rod abuts against a disc in the vertical direction at one end and abuts against the elastic piece atthe other end. The elastic sheet and the elastic sheet contact are fixed through welding, and the static sheet and the static sheet contact are fixed through welding. According to the invention, unstable contact and unstable resistance caused by riveting are avoided, the contact structure is simplified, and the cost is low; and the contact adopts a three-layer composite structure, so that the weldability is effectively improved, and the welding on substrates of the static sheet and the elastic sheet is facilitated.

Description

technical field [0001] The invention belongs to the field of temperature controllers, in particular to a low-resistance bimetal temperature controller. Background technique [0002] The thermostat refers to a series of automatic control elements that physically deform inside the switch according to the temperature change of the working environment, thereby producing some special effects and generating conduction or disconnection actions. Among them, the bimetal thermostat is a sudden jump thermostat. Its principle is to use the fixed temperature bimetal as a heat-sensitive reaction component. When the temperature of the main part of the product rises, the heat generated is transferred to the bimetal circle. On the chip, when the action temperature setting is reached, it will act quickly, and the contact will be disconnected or closed through the action of the mechanism; when the temperature drops to the reset temperature setting, the bimetal sheet will quickly return to its ...
