Abstract
A corona ignition assembly including a firing end assembly and an ignition coil assembly connected by a high voltage connection is provided. The high voltage connection includes a high voltage insulator formed of silicon rubber. A shield formed of metal surrounds the high voltage insulator. The high voltage connection also includes an upper insert formed of metal connecting the shield to the ignition coil assembly and a lower insert formed of metal connecting the shield to the firing end assembly. First portions of the outer surface of the high voltage insulator adhere to the shield, the upper insert, and the lower insert, while second portions of the outer surface do not adhere to at least one of the shield, the upper insert, and the lower insert. A metal braid can be embedded in the high voltage insulator.
