Abstract
The present invention discloses an ignition coil assembly comprising a housing of molded plastic material. A coil assembly in the housing includes a primary coil member and a secondary coil member, the secondary coil member includes a high voltage output lead. The housing includes a base wall, and an integral cylindrical stem portion which extends outwardly from the base wall along an axis. A secondary coil output lead terminal member extends in the general direction of the axis through the base wall, and is connected to the high voltage output lead at one end and terminates in a clasp portion at its other end. The clasp portion is received within the annular stem portion. The annular stem portion includes an interior annular wall and an exterior annular wall. The clasp is concentrically located within the stem portion and is spaced therefrom to thereby provide an annular clearance cavity. A coil-type retaining spring is slidingly received at one end within the stem portion and is slidably secured to the clasp portion. The other end of the spring is adapted to grip a spark plug to establish electrical contact between the coil assembly and the spark plug.
