Abstract
A magnetic core assembly for an ignition coil assembly allows unique exterior shapes to be formed by an outer insulation layer, while speeding up the manufacturing process. Generally, the magnetic core assembly comprises a core of ferromagnetic material and an overmold over the exterior of the core. The overmold generally comprises an insulating layer injection molded over the core. Various structures may be incorporated into the core assembly for injection molding, while a second insulative layer provides additional thermal and electrical insulation.
