Pen-type ignition coil

Abstract

The invention discloses a pen-type ignition coil which comprises an iron core, a primary coil body, a secondary coil body, an upper shell and a lower shell. The outer side of the iron core is provided with the primary coil body, the outer side of the primary coil body is sleeved with the secondary coil body, the upper shell and the lower shell are installed in a matched mode through a clamping groove, and the iron core, the primary coil body and the secondary coil body are all arranged in the upper shell and the lower shell; the right end of the upper shell is provided with a protecting seat, and a low-voltage binding post is arranged in the protecting seat; the lower end of the lower shell is connected with a sleeve, a high-voltage lead is arranged in the sleeve, the lower end of the high-voltage lead is connected with a high-voltage binding post, and the lower end of the high-voltage binding post is provided with an ignition plug; one end of the secondary coil body is connected with the high-voltage lead, the other end of the secondary coil body is connected with the primary coil body, and the primary coil body is connected with the low-voltage binding post. The pen-type ignition coil adopts the iron core which is transversely arranged and has the advantages of being simple in structure, compact in connection, low in production cost, long in service life, safe and reliable.

Description

【Technical field】 [0001] The invention relates to the technical field of auto parts, in particular to the technical field of a pen type 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. At present, domestically produced ignition coils are generally dry-type ignition coils that need to be connected by high-voltage wires. Dry-type ignition coils are further divided into multi-head dry-type ignition coils and single-head dry-type ignition coils. Among them, the multi-head...

AI Technical Summary

Problems solved by technology

Among them, the multi-head dry-type ignition coil is mainly used in the ignition system without distributors, which requires the connection of high-voltage wires and has a large energy loss; in addition, the multi-head dry-type ignition coil is responsible for igniting several cylinders at the same time, as long as one of the coils is damaged, it will cause The entire coil is scrapped, resulting in a great waste of resources

At present, pen ignition coils have been widely used, but due to energy and environmental reasons, the fuel will be replaced by a mixed gasoline or biofuel, such as gasoline and alcohol ethers mixed in a certain proportion, but the mixed fuel The ignition point is lower than that of pure gasoline, so the energy provided by the pen ignition coil is required to be greater. However, most of the existing pen ignition coils are primary coils, secondary coils and iron cores arranged vertically, which have complex structures and take up a lot of space. The structure is not compact and the insulation effect is poor
