Abstract
A shielded spark plug boot assembly for an ignition cable connector has a tubular elastomeric boot having a cable end portion that receives an ignition cable, an intermediate cavity portion that houses a terminal at the end of the ignition cable, and a seal end portion that receives a spark plug and seals around an insulator thereof. The shielded spark plug boot assembly also has a heat shield and a coil spring. The heat shield is mounted on the cable end portion of the elastomeric boot and it includes a metal shell that has a lower end portion which extends below the seal end portion of the elastomeric boot and which includes a conical portion that leads to a collar of reduced diameter at the lower end of the heat shield. The coil spring has an upper conical portion that is disposed and retained in the conical portion of the metal shell and a lower cylindrical portion that protrudes through the collar at the lower end of the heat shield and engages a metal portion of the spark plug to ground the heat shield electrically.
