Abstract
The invention discloses an open magnetic circuit type ignition coil. The open magnetic circuit type ignition coil comprises an iron core, a secondary coil, a primary coil and a main shell, the secondary coil and the primary coil wind on the outer side of the iron core, the primary coil winds on a coil framework on the outer side of the secondary coil, an epoxy resin layer is arranged between the secondary coil and the primary coil, the main shell is arranged on the outermost side, a bottom plate is arranged at the lower end of the main frame, an upper cover is arranged on the upper end of the main shell in a sleeving mode, a connecting block is arranged inside the upper cover, the two ends of the connecting block are each provided with a primary wiring terminal, and a high voltage output terminal is arranged in the center of the connecting block; a starting end of the secondary coil is connected with the high voltage output terminal, the tail end of the secondary coil is connected with the primary coil, and the tail end of the primary coil is connected with the primary wiring terminal. The open magnetic circuit type ignition coil is simple in structure, compact in connection, resistant to disengaging and long in service life and improves the ignition performance.
Description
【Technical field】 [0001] The invention relates to the technical field of auto parts, in particular to the technical field of an ignition coil. 【Background technique】 [0002] With the development of automobile gasoline engines in the direction of high speed, high compression ratio, high power, low fuel consumption and low emission, the traditional ignition device is no longer suitable for use. The core components of the ignition device are the ignition coil and the switch device. When the energy of the ignition coil is increased, the spark plug can generate sparks with sufficient energy, which is the basic condition for the ignition device to adapt to the operation of modern engines. There are usually two sets of coils in the ignition coil, the primary coil and the secondary coil. The primary coil uses a thicker enameled wire, usually about 200 to 500 turns with an enameled wire of about 0.5 to 1 mm; the secondary coil uses a thinner enameled wire, usually about 15,000 to 2...
