Abstract
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.
Claims12
An ignition coil (10) including a magnetically permeable core (16) having a main axis (“A”) , a primary winding (24) disposed radially outwardly of the core (16), a secondary winding spool (28) formed of electrical insulating material disposed radially outwardly of the primary winding (24), a secondary winding (30) wound on the secondary winding spool (28), and a case (34) and a shield (36) disposed radially outwardly of the secondary winding (30), characterized by:
- an insulating layer (22) comprising electrical insulating material that is non self-supporting disposed directly on the core (16), the core (16) having a plurality of iron laminations (46);
- wherein the primary winding (24) is wound directly on the insulating layer (22).
A method of making an ignition coil (10) comprising the steps of:
- (A) forming (70) a magnetically permeable core (16) having a main axis (“A”) wherein the core (16) includes a plurality of iron laminations (46);
- (B) disposing (72) an insulating layer (22) comprising electrical insulating material that is non self-supporting disposed directly on the core (16);
- (C) winding (74) a primary winding (24) directly on the insulating layer (22) wherein the primary winding (24) is disposed radially outwardly of the core (16);
- (D) disposing (76) a secondary winding spool (28) formed of electrical insulating material and having a secondary winding (30) radially outwardly of the primary winding (24);
- and,
- (E) disposing (78) a case (34) and a shield (36) radially outwardly of the secondary winding (30).
