Abstract: An ignition apparatus includes a high voltage (HV) terminal formed of stamped sheet metal configured to be disposed in a secondary winding spool, and to which a high voltage end of the secondary winding is attached and soldered. The ignition apparatus further includes an electrically conductive cup configured to surround the high voltage terminal when the secondary winding spool is inserted in the case. The high voltage terminal has one end that comes into engagement with an inner annular surface of the cup. The cup includes an annular sidewall that extends axially up to a winding flange where a HV end of the secondary winding exits a winding bay thereby surrunding the exiting HV secondary winding wire. The cup provides for a reduced electric field concentration.

Abstract: A printed circuit board (PCB) for an ignition apparatus includes a connection interface. The connection interface includes a first hole, and a second hole that is smaller than the first hole. The second hole has a pad associated therewith that is electrically coupled to a conductive trace for connecting to a system connector. The first hole and the second hole are coupled by way of a channel. The first hole is sized so as to facilitate insertion of a winding end, while the second hole is configured to facilitate a soldering operation of the winding end to the pad. The channel width is less than the diameter of the winding end so that once the winding end is in the smaller hole, the channel provides, in-effect, a retaining feature until it can be soldered.
