AI Technical Summary
When the electrical control requirements of the circuit board of existing electric tea appliances are increased, the traditional thermostat contact switch connection method cannot meet the electrical control requirements of the circuit board, resulting in complicated wiring, increased safety hazards, and affecting waterproofing and arcing safety.
The temperature controller with a dual-output structure provides two sets of electrical connection outputs through the connector and terminal block formed by the L and N pole conductive rings, combined with the contact switch driven by the thermal bimetallic actuator. The terminal block has a multi-layer structure with multiple folds and riveting, and is equipped with insulating pads to ensure a stable connection and insulation. The terminal block is separated from the moving contact arm to reduce interference.
This achieves reliable electrical control connection of the circuit board, reduces safety risks, simplifies wiring layout, and improves the safety and intelligent wiring foundation of the equipment.
