摘要： In an engine igniting coil device of the open-magnetic-circuit type that has a bobbin having a hollow axis having a circular section in which a rod-shape core is inserted, the core is formed of a plurality of iron plates having different widths and laminated to have a substantially circular section and the thus formed core is splitted in the direction perpendicular to the lamination into a plurality of parts in order to increase a space factor of the core in the bobbin's hollow axis having a circular section and to easily accommodate the core in the bobbin's hollow axis having a circular section assuring a high space factor of the core therein and reducing eddy-current core-loss to improve an output factor of a secondary voltage.

摘要： An engine igniting coil device which comprises a coil case composed of a first cylindrical case and a second case having a small tubular hole in its center portion and fitted at its open end in an open end of the first case to form a close end of the coil case and an internal unit assembled from a primary side coil bobbin, a secondary-side coil bobbin having a high-voltage terminal holder projecting from a center of its end flange portion, a rod-shape core and a high-voltage terminal attached to the high-voltage terminal holder and having a contact for electrically connecting an ignition plug thereto and which is characterized in that the internal assembly is mounted in the coil case by inserting the high-voltage terminal holder in the small tubular hole of the secondary case with a tip of the contact projected outwardly therefrom and formed integrally with the coil case by injecting melted insulating resin into the coil case: thus, the inner assembly can be easily located and reliably fixed at a given place in the coil case with no additional member, assuring precise forming of an integral device by potting with resin.
