Abstract

The invention provides an ignition coil. The ignition coil comprises a shell and a connector mounted on the shell, wherein the connector is provided with a circuit board; the shell is internally provided with a coil combined body; the coil combined body comprises an iron core, a primary framework, a primary coil, a secondary framework and a secondary coil, and further comprises a plurality of circuit communication devices; each circuit communication device comprises a plug arranged on the circuit board and a socket arranged at the corresponding position of the primary framework; and when the coil combined body and the connector are mounted on the shell respectively, the plugs and the sockets are combined so that an input end of the primary coil is communicated with the circuit board. With the adoption of the technical scheme, the ignition coil provided by the invention is reliable to connect and the electric property of the product is guaranteed.

Description

technical field [0001] The invention relates to an ignition coil. Background technique [0002] In the ignition system of an automobile engine, the ignition coil is an executive component that provides ignition energy for igniting the air and fuel mixture in the engine cylinder. It is a special pulse booster based on the principle of electromagnetic induction. It switches the low voltage of 8-16V on and off according to the set frequency to make the secondary generate a voltage of 20-40KV to generate electric sparks through the spark plug. The internal electrical components of the ignition coil are connected in a complicated way, which affects the working performance of the product. SUMMARY OF THE INVENTION [0003] In order to overcome the above disadvantages, the technical problem to be solved by the present invention is to provide an ignition coil with simple installation and reliable connection. [0004] In order to achieve the above purpose, the technical solution a...
