Claims

[Scope of Claim for Utility Model Registration] A terminal board provided inside the case of the watt-hour meter opposite to an external terminal board provided outside the case of the watt-hour meter, which is fixed to the inner surface of the case of the watt-hour meter. A plurality of current terminal fittings are vertically protruded from the external terminal board toward the inside of the case on the surface of the board, and the current terminal fittings are inserted into the through hole in the center of the current transformer case to form a support member for the current transformer. In addition, the surface of the board is provided with a current transformer fixing reference part that protrudes in the same direction as the current terminal fitting and comes into contact with the outer periphery of the current transformer case, and the surface of the board is provided with a block-shaped part. A voltage terminal mounting portion is integrally formed, and a plurality of grooves extending in the same direction as the current terminal fittings are formed in the voltage terminal mounting portion, and within these grooves, the voltage terminal fittings and the power terminal fittings extending from the external terminal board are formed. An internal terminal board for a power meter, characterized in that it is connected to a voltage lead wire inside the meter.
