ANTI-STEALING ELECTRIC ENERGY METER

WIPO Patent Application WO/2020/248952

A1

The present utility model relates to an anti-stealing electric energy meter, comprising a meter cover and a base arranged in sequence from front to back, the meter cover is arranged on the base, and a circuit board is arranged in the space enclosed by the meter cover and the base, the circuit board has metal contacts connected to the live wire, characterized in that: the meter cover is at least partially surrounded by a conductive element used to conduct external electricity entering the meter to the outside of the meter, the conductive element is electrically connected with the metal contacts on the circuit board. When external static electricity enters through the gap between the base and the meter cover, the conductive element is closer to the gap, the static electricity is preferentially transferred to the corresponding position of the closest conductive element, the conductive element is electrically connected with the metal contacts on the circuit board, the metal contacts lead to the live wire, and finally lead the static electricity to the outside of the electric energy meter, preventing the electric elements in the electric energy meter from being damaged by static electricity.
