摘要： An ignition coil device for an internal combustion engine includes an air gap between the two heat generating sources, the coil assembly and the power transistor unit, such that the coil assembly and the power transistor unit are thermally isolated from each other. Further, the primary winding bobbin has an inner projection inserted into the air gap of the core to maintain the gap. Furthermore, the primary winding bobbin and the secondary winding bobbin each has a first and a second bobbin attachment portion. First the high voltage tower attachment portion of the high voltage tower is engaged with the bobbin attachment portion on the secondary winding bobbin and the connector attachment portion of the connector is engaged with the bobbin attachment portion on the primary winding bobbin, to form respective integral sub-units. Then, the second bobbin attachment portion on the primary winding bobbin is engaged with the second bobbin attachment portion on the secondary winding bobbin, to form an integral assembly, which is then inserted into the mold resin casing after the necessary electrical connections are made outside of the mold resin casing. The interior wiring for connecting the power transistor unit to the connector extends outside of the core such that adverse effects of the flux in the core on the interior wiring are prevented.
