Ignition coil for internal combustion engine

摘要

A conductive member (513, 535b, 530b, 540b, 550) is disposed between a secondary spool (510) and a high tension terminal (27) to shield the wire connecting the secondary coil (512) and the high tension terminal (27). The conductive member has a wide surface facing the low tension components to moderate the electric field strength around low tension components, thereby preventing trees from growing in the insulating filler of the ignition coil (2). <IMAGE>
