SPARK PLUG BOOT COVER ASSEMBLY

摘要

An electrically conductive cover which in assembly is received over at least part of a spark plug boot and at least part of a nut portion of a metal body of a spark plug received in the boot. The cover may have an opening through which an arm portion of the boot extends which arm portion receives an electric wire for supplying a current at a high potential voltage to the spark plug.

主权项

1. A conducting cover for a spark plug boot for a spark plug having an electrode terminal and an insulator carried by and projecting from a conducting metal shell with a nut portion, the conducting cover comprising:
a separate body of an electrically conductive material having an annular portion configured to receive therein at least part of a boot configured to receive therein the terminal and at least part of the insulator of the spark plug, and the body having an integral annular base portion configured in assembly to extend around the periphery and over at least part of the nut portion of the metal shell of the spark plug and frictionally engaging the nut portion in an electrically conductive connection with the metal shell.
