Ignition coil

摘要

An ignition coil (10) has a core (16) composed of a plurality of laminations (46) and about which is directly disposed an insulating layer (22). A primary winding (24) is wound directly on the insulating layer (22), thereby eliminating the need for a primary winding spool and recovering the space conventionally occupied by such a primary winding spool for use in allocating greater space to the core (16) and/or windings.
