ABSTRACT:
A transformer or power supply apparatus as well as a method for making the same is provided. A coil assembly, including a bobbin (10 or 62), windings (30, 31), and terminals (27), retains core laminations (14) forming a transformer or power supply assembly. The assembly is placed within injection molding molds and a thermoplastic or thermosetting material is injection molded to partially or fully encapsulate the assembly, producing an improved transformer or power supply structure.
