Ignition coil of internal combustion engine

Abstract

Abstract PURPOSE: To simplify high tension wiring and improve both voltage and vibration resistance of an ignition coil, by forming high tension diodes incorporated into the ignition coil. CONSTITUTION: A core 15 is forced in a center hole of a bobbin 7 with primary coils 2, 3 wound around it, a in order to form the core of a closed magnetic circuit with a spacer 17 and a core 16 surrounding a case 14 in which a secondary coil 6 is placed. A case 18 made of synthetic resin contains high tension diodes D 1 WD 4 , one end of each diode being connected to high tension terminals 19W22 respectively which are formed integrally into the case 18 through thermosetting of epoxy resin compound 30 filled in the case 18. Diode terminals 23, 24 are connected to secondary terminals 12, 13 and all components are buried in synthetic resin 25 as an integral body to form a solid ignition coil 1.
