Abstract
An angular pin is used in a connecting portion of each component, and a plated copper wire for electrical connection of the component is wound at several turns around the angular pin.
Claims2
An integrated ignition coil device comprising:
- ignition coils respectively disposed in cylinders of a multi-cylinder internal combustion engine;
- plural ignition coil modules for respectively supplying a high voltage for ignition to said ignition coils, each of said ignition coil modules including a primary coil, a secondary coil, and a core, said ignition coil modules being housed in a case;
- a primary voltage input portion;
- and
- secondary high voltage terminals for respectively supplying a high voltage to said ignition coils, wherein
- a primary voltage input terminal of said primary voltage input portion and a connecting portion of a primary coil terminal of each of said primary coils are connected to each other by a plated copper wire,
- each of said terminals has a connecting portion which is formed into an angular pin-like shape having plural edges in a section, and
- said plated copper wire is subjected to wrapping connection in which said plated copper wire is wound at several turns around said angular pin-like connecting portion of each of said terminals.
