Abstract

A presently-preferred embodiment of an electrical-energy meter comprises a base adapted to be mounted on a supporting surface, a current sensor assembly comprising a plurality of contact blades extending through the base and adapted to electrically contact a conductor of electrical energy, and a current transformer mechanically coupled to the base and electrically coupled to the contact blades. The electrical-energy meter further comprises a circuit board assembly comprising a main circuit board electrically coupled to the current transformer and the contact blades. The electrical-energy meter also comprises a circuit-board support member comprising a rim portion fixedly coupled to the base, and a first bracket adjoining the rim portion. The first bracket has a first and a second leg each extending away from the rim portion and the base and each being adapted to securely engage the main circuit board.

Claims

1. An electrical-energy meter, comprising:

a base adapted to be mounted on a supporting surface;

a current sensor assembly comprising a plurality of contact blades extending through the base and adapted to electrically contact a conductor of electrical energy, and a current transformer mechanically coupled to the base and electrically coupled to the contact blades, the current transformer being adapted to produce an electrical output proportional to an electrical current in the conductor of electrical energy;

a circuit board assembly comprising a main circuit board electrically coupled to the current transformer and the contact blades, the circuit board assembly being adapted to calculate and display a cumulative amount of electrical energy passing through the conductor of electrical energy based on the electrical output of the current transformer and a voltage of the conductor of electrical energy; and

a circuit-board support member comprising a rim portion fixedly coupled to the base, and a first bracket adjoining the rim portion, the first bracket having a first and a second leg each extending away from the rim portion and the base and each being adapted to securely engage the main circuit board.
