An ignition coil assembly module (40) 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 (46). From innermost to outermost, the succession is: a) a secondary bobbin (48), b) a secondary coil (58), c) a secondary encapsulant (194) encapsulating the secondary coil, d) a primary bobbin (50), e) a primary coil (56), f) an inner wall (181) of an environmental shield (42) encapsulating the primary coil, g) a ferromagnetic shell (52), and h) an outer wall (180) of the environmental shield encapsulating the shell. The primary bobbin forms a liquid container for holding secondary coil encapsulant. A terminal (100) extends through a transverse wall (71) of the primary bobbin for carrying secondary current from the secondary coil to another terminal (118) on the other side of the transverse wall that connects to a spark plug (80). The two terminals are connected together by a mechanical locking connection that keeps them together when the module is disconnected from the spark plug.

[ What is claimed is:] [1.] An ignition coil assembly module having an imaginary centerline and comprising:a magnetic core;a secondary coil;a secondary bobbin comprising a cylindrical wall forming a hollow interior within which the magnetic core is disposed and an exterior on which the secondary coil is disposed;a primary coil; anda primary bobbin comprising a cylindrical wall bounding a hollow interior within which the secondary bobbin, including the secondary coil and the core, are disposed and comprising an exterior on which the primary winding is disposed;the primary bobbin further comprising a transverse wall disposed transverse to the centerline across the hollow interior of the primary bobbin and containing an electric terminal that passes through the transverse wall, that has electric continuity to one termination of the secondary coil within the hollow interior of the primary bobbin, and that serves to conduct electric current from the secondary coil to a terminal of a spark plug.
