ABSTRACT:
An ignition coil for an internal combustion engine has a housing composed of an insulating material and having an insertion opening, at least one ring-shaped core composed of a soft magnetic material and having a portion insertable in the housing, a primary coil body and a secondary coil body, a primary coil and a secondary coil wound on the primary coil body and the secondary coil body and arranged coaxially to one another on the portion of the core, the housing being provided with a high voltage dome extending substantially perpendicularly to a central axis of the coil bodies, a connecting pin insertable along a longitudinal axis of the high voltage dome and connected via a diode with a high voltage winding end of the secondary coil. The connecting pin, the diode and the coil bodies with the coils together form an operationally premounted assembly insertable through the insertion opening in the housing. A spacer connected with one of the coil bodies. The housing completely surrounds the core. The connecting pin and the diode is received in the spacer, the diode is arranged coaxially to the longitudinal axis of the high voltage dome.
