ABSTRACT:
A heat shielded spark plug boot assembly for an ignition cable connector comprises an L-shaped tubular, elastomeric boot having a cable end portion for receiving an ignition cable, a seal end portion for receiving a spark plug and sealing around its outer insulated part and an intermediate cavity portion for housing a terminal for connection with the spark plug. An L-shaped heat shield is stamped from flat metal heat stock and then bent and formed to provide a pair of spaced apart, generally parallel L-shaped sides, a back side having an inwardly indented semi-circular upper end and with the sides at their upper ends being rolled on the semi-circular upper end of the back and toward and into engagement with each other to form a semi-circle and longitudinal seam at their free edges. The upper portion of one side has a tab whose free end is received within a complementary shaped recess of the other upper end of the other side so as to interlock the two sides together. The boot is assembled to the heat shield by press fitting the same therein through the open side of the shield and snapping the boot past a pair of indents on the sides of the heat shield.
