Background Technology
[0002] British standard plugs are power plugs designed with the British standard as a reference. They are power connectors that are inserted into a power source, connecting the appliance to the power supply for operation. When charging new energy vehicles, the power plug generates a significant amount of heat, posing a safety hazard. Therefore, a temperature sensor is needed to monitor the internal temperature of the plug in real time to reduce this hazard. The accuracy of the resistance signal fed back by the temperature sensor is crucial for temperature-controlled plugs. Existing British standard plugs have poor internal structural stability, making them difficult to shape and resulting in high manufacturing costs. Utility Model Content
