Description

Technical Field

[0001] The utility model relates to the technical field of ignition coils, in particular to an ignition coil with a grounded shell. Background Technique

[0002] The ignition system is a crucial component in the engine management system, and its core components include an ignition coil and a spark plug. As a key element for energy conversion, the ignition coil uses the principle of a transformer to convert primary low-voltage electrical energy into secondary high-voltage electrical energy, and then ignites the mixture gas in the cylinder through the spark plug to drive the engine to run. Therefore, the performance of the ignition coil directly affects the working efficiency and stability of the engine;

[0003] In the design of traditional ignition coils with grounded shells, the grounded shell and the ignition coil housing are mainly connected by bolts. Due to the use of bolt connections, professional tools are required for tightening during the installation process, which not only increases the complexity and time cost of installation, but also places higher requirements on the skill level of installers. After long-term use, especially in humid or corrosive environments, the bolts and connection parts are prone to rust. Rust not only affects the stability of the connection, but may also lead to poor grounding, thereby affecting the working performance of the ignition coil. Therefore, we propose an ignition coil with a grounded shell to solve the above problems. Content of the Utility Model
