ABSTRACT:
The present invention is a standardized transformer battery charger assembly for assembling a self-contained transformer battery charger with a built-in printed circuit board (PCB). The transformer batter charger assembly comprises a two-piece casing for housing a transformer unit and the printed circuit board. The PCB has a heat exchange relationship with the casing. The transformer unit includes a primary piece having a primary bobbin for accommodating a primary winding, and a secondary piece having a secondary bobbin for accommodating a secondary winding. The assembly also comprises electrical input pins mounted to the primary piece and connectable with the primary winding, secondary pins non-twistably and non-extractably attached to the secondary piece for supporting the PCB and electrically connecting the secondary winding with input terminals of the PCB, and terminal strips non-twistably and non-extractably attached to the primary piece and non-rotatably interlocking the second piece and also supporting the PCB at another end, and further electrically connected with output terminals of the PCB for serving as output terminals of the transformer battery charger. With the standardized transformer battery charger assemblies, various self-contained transformer battery charges with customized characteristics can be produced by selecting a desired combination of the respective number of windings on the primary and secondary bobbins and selecting suitable PCBs.
