Description

Technical Field

[0001] The utility model relates to a field, in particular to a separable pen-shaped ignition coil. Background Art

[0002] The ignition coil is a key component in the ignition system of a gasoline engine. It is responsible for converting the low-voltage electricity (usually 12V) of the vehicle into high-voltage electricity to ignite the mixture gas (a mixture of air and fuel) in the cylinder. The separable design allows certain parts of the ignition coil (such as the ignition module or the coil body) to be repaired or replaced individually without replacing the entire ignition coil. This design greatly simplifies the repair process, reduces the repair cost, and improves the repair efficiency.

[0003] Since the ignition coil is an important component in the engine ignition system, its working environment is harsh and it is easily affected by factors such as high temperature, high pressure, and vibration. Therefore, it may malfunction or be damaged during use. If the ignition coil adopts an inseparable design, once a fault occurs, the entire ignition coil needs to be replaced, which will increase the repair cost and repair time. However, with a separable design, different parts of the ignition coil (such as the ignition module and the coil body) can be separated, so that only the faulty part needs to be replaced when a fault occurs, without replacing the entire ignition coil, thus improving the convenience of repair and replacement.

[0004] Therefore, in view of the fact that some existing ignition coils adopt an integral structure, the working environment of the ignition coil is harsh and it is easily affected by factors such as high temperature, high pressure, and vibration. Therefore, it may malfunction or be damaged during use. Once a fault occurs, the entire ignition coil needs to be replaced, which will increase the repair cost and repair time. Once a fault occurs, the entire ignition coil needs to be replaced, which will increase the repair cost and repair time. A separable pen-shaped ignition coil can be designed. When the ignition coil malfunctions, due to the separable design, usually only the problematic part (such as the ignition module or the coil body) needs to be replaced, without replacing the entire ignition coil. This greatly reduces the repair cost and enables the vehicle owner or repair station to handle the repair of the ignition system more economically. Summary of the Utility Model

[0005] In order to overcome the problems that some ignition coils adopt an integral structure, the working environment of the ignition coil is harsh and it is easily affected by factors such as high temperature, high pressure, and vibration. Therefore, it may malfunction or be damaged during use. Once a fault occurs, the entire ignition coil needs to be replaced, which will increase the repair cost and repair time. Once a fault occurs, the entire ignition coil needs to be replaced, which will increase the repair cost and repair time.
