1. The composition and structure of the ignition coil of Cars Ignition Coil Manufacturers

The ignition coil is mainly composed of iron core, primary and secondary coils, bakelite cover, porcelain cup and so on.

The core is made of laminated silicon steel plates and wrapped in a hard paper sleeve.

A secondary coil is wound on the paper sleeve, and its wire is an enameled wire with a diameter of 0.06 to 0.10 mm, with 11,000 to 23,000 turns.

In order to enhance the insulation, the secondary winding is also wrapped with several layers of cable paper. The outer surface of the primary winding is conducive to heat dissipation. The diameter of the enameled wire is generally 0.5-0.8mm, with 220-330 turns, and several layers of insulated cable paper are also wrapped on the outside.

There is also a steel sleeve for magnetic conduction between the primary coil and the shell. There is an insulating porcelain cup at the bottom of the shell and a bakelite cover on the top. The cover is equipped with a low-voltage connection post for connecting a breaker, a high-voltage line jack, a "switch" connection post and a "power switch" connection post. There are shaped high edges around the inside of the bakelite cover to ensure the insulation performance of the high-voltage joints.

The shell is filled with insulating oil or asphalt to enhance the insulation performance and prevent the intrusion of moisture.

Distributor Ignition Coils Wholesale ignition coil selection should be consistent with the polarity of the battery connection, which will help reduce the working voltage of the spark plug and improve the ignition performance.
