Abstract:
1. A stick ignition coil apparatus for an ignition plug, comprising: a primary coil arrangement, which includes a primary winding and a primary spool, wherein the primary winding is wound around the primary spool; a secondary coil arrangement, which is located radially inward of the primary coil arrangement, wherein: the secondary coil arrangement includes a secondary winding and a secondary spool; the secondary winding is wound around the secondary spool; and an annular corner portion is formed on a distal projecting portion of the secondary spool; a center core, which is located radially inward of the secondary coil arrangement; a coil case, which is located radially outward of the primary coil arrangement; a high voltage terminal, which is located at a distal end of the secondary coil arrangement, wherein: the high voltage terminal is shaped into a tubular form, an opening of which faces toward a proximal end of the stick ignition coil apparatus; and the high voltage terminal is electrically connected with one end of the secondary winding; a spring case, which holds a spring for electrically connecting the high voltage terminal with the ignition plug; and dielectric resin, which is filled in a space defined radially inward of the coil case, wherein an open end of the high voltage terminal is directly connected to the annular corner portion of the distal projecting portion of the secondary spool.
