Abstract
An ignition coil assembly module (,) that can be connected to and disconnected from an engine spark plug. The module elements are arranged as a succession of cylindrical layers about a central ferromagnetic core (,). From innermost to outermost, the succession is: a) a secondary bobbin (,), b) a secondary coil (,), c) a secondary encapsulant (,) encapsulating the secondary coil, d) a primary bobbin (,), e) a primary coil (,), f) an inner wall (,) of an environmental shield (,) encapsulating the primary coil, g) a ferromagnetic shell (,), and h) an outer wall (,) of the environmental shield encapsulating the shell. The primary bobbin forms a liquid container for holding secondary coil encapsulant. A terminal (,) extends through a transverse wall (,) of the primary bobbin for carrying secondary current from the secondary coil to another terminal (,) on the other side of the transverse wall that connects to a spark plug (,). The two terminals are connected together by a mechanical locking connection that keeps them together when the module is disconnected from the spark plug.
