Claims

[Scope of utility model registration request]

In a power consumption measuring device in which a power measurement display main body and a terminal main body are removably connected and the measurement display part and the terminal part are electrically connected by a connector, the terminal part is connected to an external connection terminal, The measurement display section is equipped with a voltage transformer that converts the load voltage of the circuit under test into a voltage proportional to the load voltage, and a current transformer that converts the load current into a current proportional to the load voltage. A power pulse train conversion circuit that converts into a multiplication pulse train via the connector, a counting display circuit that counts and displays the pulses from the power pulse train conversion circuit, and a power pulse train conversion circuit that obtains a DC voltage from the voltage of the circuit under test. and a power supply circuit that supplies DC voltage to the count display circuit,
1. An electric power meter characterized in that a concavo-convex portion is formed at a joining portion of a metering display body and a terminal body of different ratings to prevent the two bodies from joining together.
