Abstract: A disk sensing optics assembly is mounted directly on the register circuit board of an electronic energy meter. The molded optics assembly includes an central cavity adatped to receive a discontinuous rotating shutter, and pockets on either side dimensioned to hold and position pairs of light emitters and detectors on opposite sides of the shutter to detect speed and direction of rotation of the shutter. Apertures through the rear of the housing are adapted to position and secure the electrical leads from the light emitters and detectors within the housing and are soldered to the register printed circuit board. Positioning means integral with the housing and register circit board space, position, and secure the disk sensing optics and the assembly to the register circuit board with the electrical leads properly positioned for soldering to the circuit board.

Abstract: An electronic register in an electric energy meter includes a power supply transformer mounted on and through the register circuit board which is positioned between the base of the meter and the register indicator. Shrouds isolate and insulate the connections within the shrouds to the primary winding of the transformer, and positioning members are provided to secure the transformer to the circuit board while at the same time providing positioning for the secondary winding terminal pins which pass through the circuit board to enable their proper connection, such as by soldering, to the circuit board. A unitary molded bobbin provides a spool for the transformer windings and core, the positioning members, the shrouds, and securing of the secondary winding terminal pins.

Abstract: An optical communications shielded link assembly is provided from outside the cover of an electronic power meter to the register assembly without connecting cables and including an optical coupler on the exterior of the cover and an optical shroud assembly between the cover and a light emitter and detector positioned within the power meter around a light emitter and light detector. The optical shroud includes a spring loaded sleeve to fill the space between the cover and the register assembly and shield against ambient light. The sleeve includes projections moving within an annular slot with sufficient looseness to enable 3 axes positioning. Retaining and positioning means are provided for the components of the assembly. A detachable magnetic coupler can be connected to the cover mounted coupler or through a programming adapter detachably connected when the cover is removed.

Abstract: An electronic time of use or demand register is provided for selective addition to a watthour meter in an energy meter. The electronic register is configured for parallel mounting beside the watthour meter to minimize space and includes an integral register enclosure for properly assembling and securing various components in positive operational relationships such as positioning the optical detection assembly relative to the rotating castellated shutter and in turn positioning the optical communications link relative to the optical detection assembly. The register enclosure additionally includes integral means for mounting the electronic register within the energy meter and for selectively adding and positioning a plurality of optional features.
