The figure is a sectional view taken along the line IV-IV of the same as above, and FIG. 5 is a sectional view similar to FIG. 4 of another embodiment of the molded ignition coil of the present invention.
In the figure, 1 is the case, 2 is the primary coil, 2' is its bobbin, 2a is the collar, 3 is the secondary coil, 3' is the bobbin, 6 is the injected thermosetting resin, 7 is the iron core, and 8 is the Positioning The protrusion 9 on the collar of the primary coil bobbin illustrated as one means also indicates a diagonally cut portion at the corner of the collar.

Claims

[Scope of Claim for Utility Model Registration] A primary coil and a secondary coil each wound around a bobbin are housed in a bottomed case with the outside of the secondary coil surrounded by the secondary coil, and a thermosetting resin is placed inside the case. In the molded ignition coil, the iron core is passed through the bobbin of the secondary coil, and the inner shape of the primary coil bobbin is made to match the cross-sectional shape of the iron core, and then the outer surface of the iron core is molded. The molded ignition coil is characterized in that the flange of the bobbin of the secondary coil is provided with a positioning means for concentrically positioning both coils while making contact with the inner surface of the bobbin of the secondary coil and maintaining a gap therebetween.
