PURPOSE:To secure the insulation distance between adjoining high potential terminals by alternately assembling plural transformers contained in one case in the different directions. CONSTITUTION:Within an iron core 3 comprising an inner iron core 3a and an outer iron core 3b of the primary coil 4 and the secondary coil 5 looping with each other to form a closed magnetic e', the outer iron core 3b is arranged on the position protruding from the secondary coil 5. At this time, three transformers in such a constitution are assembled into a case 1 to be arranged so that the outer iron core 3b of respective transformers may alternately take different directions. On the other hand, the end of the primary coil 4 is connected to the terminal 7 insert-molded into the case 1 while the output end of the secondary coil 5 is connected to the high potential terminal 6 also insert- molded into the case 1. Furthermore, the high potential terminal 6 is to feed the title ignition coil with the high potential generated in the secondary coil 5 through the intermediary of a high potential cord to be inserted into a high potential tower 2. |
