Technical Field
[0001] This utility model relates to the field of automotive ignition system technology, and in particular to an improved double-layer magnetic circuit ignition coil device. Background Technology
[0002] The ignition coil is a crucial component of an automotive engine's ignition system. Its function is to convert the low-voltage direct current supplied by the car battery into high-voltage electricity sufficient to generate an electric spark between the spark plug electrodes, thereby igniting the air-fuel mixture and enabling the engine to operate normally. Traditional ignition coils have certain limitations in performance, heat dissipation, and insulation. For example, an inadequately optimized magnetic circuit structure leads to low energy conversion efficiency; poor heat dissipation during prolonged operation affects coil performance and can even cause damage; and inadequate insulation can easily lead to leakage and short circuits, affecting the reliability and safety of ignition. Therefore, improvements to the ignition coil system are needed to enhance its overall performance. Utility Model Content

On this structure, a first enameled wire is wound counterclockwise to form a primary winding coil, and a second enameled wire is wound to form a secondary winding coil. This is used for converting low-voltage electricity to high-voltage electricity to achieve the ignition function. The enameled wire uses highly conductive and heat-resistant materials to ensure stable and safe current transmission. Next, small mica sheets and large mica sheets are respectively placed below the primary and secondary winding coils for insulation. The process involves heat dissipation; subsequently, the first and second enameled wires are passed through through holes in the aluminum plate, and fiberglass sleeves are fitted over them. Heat shrink tubing is then fitted onto the outer ends of the fiberglass sleeves, and cable ties are used to bind and secure the fiberglass sleeves. After that, terminals are installed at the ends of the first and second enameled wires for connecting to an external power supply and spark plugs to realize current input and output. Finally, a thermistor is installed inside the device to monitor the operating temperature, and several silicone pads are configured inside the device to provide buffering and auxiliary insulation, ensuring the stable operation of the entire improved double-layer magnetic circuit ignition coil device.
