When the meter is connected with the external wire, insert the wire end of the external wire into the power socket of the meter junction box, and then crimp the wire end into the meter box to complete the power connection,

If the conductor is directly connected with the meter, it is easy to overheat and burn the meter;

For this reason, people use the electricity meter pin for conductive connection. The electricity meter pin can better integrate the electricity meter and the wire contact surface to form a copper aluminum electricity meter pin for power transmission, including the pressure pipe and the pin end. The pressure pipe is made of aluminum, the pin end is made of copper, and the pressure pipe and the pin end are friction welded to form a transition section, which is collectively referred to as the copper aluminum pin.
