    摘要: 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.

    摘要: An ignition apparatus includes a core, primary and secondary windings and a loop-shaped magnetic return path structure. The structure includes layers of wound strip steel or wound ferritic wire stacked in an outward fashion. The core is placed in an interior of the loop forming at least one air gap between a core end surfaces and the structure. A combined core and magnetic return path structure includes a continuous loop formed by winding ferritic wire either on a spool or on a mandrel and is then bonded. The bonded winding is cut to form two C-shaped portions. Each C-shaped portion has a central yoke that extends into a pair of parallel legs. The C-shaped portions are re-assembled over primary and second windings so that the legs form a pair of parallel branches. One branch acts as the core and the other branch acts as the magnetic return path.

    摘要: An ignition apparatus having twin spark high-voltage outputs incorporates features of a pencil coil wherein at least a portion of a transformer assembly is disposed within a spark plug well when installed in an internal combustion engine, thereby reducing the space required on the top of the engine. A secondary winding spool is configured to retain a secondary winding in first and second portions, wound either the same way for use in waste spark ignition systems or in opposite orientations for two-plug-per-cylinder systems. An alternate configuration includes an isolated shield that is internal to the case.

    摘要: A spark plug coil assembly includes a primary core inside a secondary winding spool that is formed with a closed end. A terminal is embedded in the closed end of the spool and the secondary windings are terminated to the terminal, with the terminal being couplable to a spark plug. Ignition voltage generated in the secondary windings is thus routed to a center of the secondary windings to terminate at the terminal. No pole piece need be disposed between the primary core and the closed end of the spool.

    摘要: A plastic case surrounds a primary winding of a multicharge ignition system, and has a rib in which the high voltage end is routed back to the low voltage end, so that the low and high voltage ends can be closely juxtaposed with each other while advantageously permitting the primary winding to have one and only one winding layer to reduce resistance and size. The rib of the case extends into the slot of the magnetic shields of the winding.
