Ignition coil manufacturing method for internal combustion engines spark plug, involves molding secondary coil and carcass assembly, in dielectric material assuring secondary coils impregnation and primary carcass formation

摘要

The method involves winding a primary coil (23) concentrically and externally with respect to a secondary coil (15), and electrically isolating the coil (23) from the coil (15). The coil (15) is wound on a secondary carcass (11) made from dielectric material. The coil (15) and carcass assembly is molded in a dielectric material assuring an impregnation of the secondary coil and a formation of a primary carcass (21). An independent claim is also included for an ignition coil for a spark plug of an internal combustion engine.
