Patent number: 6522232Abstract: An ignition apparatus includes a high voltage (HV) terminal formed of stamped sheet metal attached to a secondary winding spool, and to which a high voltage end of the secondary winding is soldered. The ignition apparatus further includes an electrically conductive cup formed of stamped aluminum or brass that is disposed in a case and is configured to receive the high voltage terminal when the secondary winding spool is inserted in the case. The high voltage terminal has a spring tab or the like that is biased radially outwardly into engagement with an inner annular surface of the cup. A bottom outer surface of the cup is arranged to be engaged by a high voltage spring or the like for making the connection to the spark plug. The cup is substantially free of burrs, sharp edges, and the like, and therefore reduces localized occurrences of high electric field concentrations, which could otherwise lead to insulating material, and thus ignition coil, failure.Type: GrantFiled: July 2, 2001Date of Patent: February 18, 2003Assignee: Delphi Technologies, Inc.Inventors: Mark Albert Paul, Albert Anthony Skinner, Harry Oliver Levers, Jr.

Patent number: 6232863Abstract: An ignition coil for a spark ignition engine generally includes primary and secondary windings disposed about a magnetic core. The secondary winding is wound around a spool. The spool includes a cylindrical body having opposite first and second ends and a winding section between the ends. A conical winding surface at one of the ends tapers from a large diameter at the one end to a smaller diameter. A grooved surface extends axially toward another of the ends of the body and extends to adjacent the smaller diameter of the conical surface. The grooved surface contains longitudinally spaced continuous circular grooves that have unequally angled sides. The sides toward the one end are sloped at a greater angle relative to a radial direction than are the sides toward the other end. The secondary winding is wound around the winding section forming a plurality of turns of wire wound one over the other at a desired angle. The grooves are sized such that only one turn of the wire is disposed within each groove.Type: GrantFiled: March 3, 2000Date of Patent: May 15, 2001Assignee: Delphi Technologies, Inc.Inventors: Albert Anthony Skinner, Mark Albert Paul, Viorel N.
