  • Spark plug connector assembly
    Patent number: 4009924
    Abstract: A spark plug connector assembly comprises a sheet metal terminal and a spring clip embracing the forward barrel portion thereof. The clip has four dimples projecting through two forward slots and two rear slots of the barrel portion. The barrel portion is fore-shortened and the forward slots are open at the forward end of the terminal to prevent the terminal from binding on the spark plug terminal during detachment at high angles. The slot and dimple arrangement is such that proper assembly of the spring clip is assured and the spring clip is reversible. Tabs are also provided on the barrel portion to assure proper seating on the spark plug terminal.
