ABSTRACT:
An electric meter particularly characterized by a small number of moving parts and simplified assembly. A coil assembly initially including integral support elements which permit connection of pivot bearings or taut bands is adapted to be accurately positioned for rotation on the supporting base by inserting the assembly into the base. Cooperating locating surfaces on the base and coil assembly provide for accurate positioning of the support elements so the axis of rotation of the coil is in a predetermined position relative to a magnetic circuit of the meter. After insertion of the coil assembly, the bridging elements are severed. A coil support form of unique construction includes motion limiting elements which cooperate with surfaces of the magnetic circuit to limit the permissible extent of movement of the coil, in the event of shock or impact, to positions well within the elastic limit of the supports which mount the coil for rotation. The coil support halves connected together in electrically insulated relation to each other. Damping rings can be secured directly to the respective coil support halves, after the coil form is assembled.
