The core components of the ignition device are an ignition coil and a switching device, the energy of the ignition coil is increased, and a spark plug can generate a spark with enough energy, which is the basic condition for adapting the ignition device to the operation of a modern engine.

A typical ignition coil has two sets of coils, a primary coil and a secondary coil, inside it. The primary coil is wound by a thicker enameled wire, and is usually wound by about 200-; the secondary coil is wound with thinner enameled wires, usually around 15000-. One end of the primary coil is connected with a low-voltage power supply (+) on the vehicle, and the other end is connected with a switching device (a breaker). One end of the secondary coil is connected with the primary coil, and the other end of the secondary coil is connected with the output end of the high-voltage wire to output high-voltage electricity.

The ignition coil can change low voltage on the vehicle into high voltage because of the same form as common transformer, the primary coil has larger turn ratio than the secondary coil. However, the ignition coil works differently from a common transformer, and the working frequency of the common transformer is fixed at 50 Hz.

The existing ignition coil comprises an ignition coil main body, a connecting plug structure arranged on the ignition coil main body, a high-voltage wire tube body and a low-voltage wire tube body arranged in the ignition coil main body. The joint of the fixing clamping block and the ignition coil main body in the connecting plug structure is connected by adopting a gluing material, and the phenomenon of looseness of the connection often occurs in the use process, so that the fault of poor contact is further caused.
