Description

Technical Field

[0001] This utility model relates to the field of ignition coil technology, specifically to a high-stability, anti-interference ignition coil. Background Technology

[0002] In modern automotive ignition systems, the block ignition coil (also known as a direct ignition coil or COP, Coil-On-Plug) is mounted directly on the spark plug, providing the necessary high-voltage electricity to ignite the fuel gas. This configuration simplifies the design of the ignition system, improves energy transfer efficiency, and reduces energy loss. However, this design also faces several challenges, particularly in terms of interference immunity and stability.

[0003] In actual use, the existing ignition coils are relatively unstable due to fluctuations in the circuit pulses. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a highly stable, anti-interference ignition coil. Through a shielding layer structure, an adhesive shielding layer can be used. This shielding layer is a conductive rubber structure containing conductive particles evenly distributed within the silicone rubber. Pressure forces these conductive particles into contact, effectively shielding electronic devices, such as servers, from electromagnetic waves generated during operation. The external metal honeycomb panel structure enhances the structural connection between the shielding layer and the enclosure. Furthermore, the honeycomb structure improves filtering efficiency. This effectively solves the problems in existing technologies.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a high-stability anti-interference ignition coil, comprising: a sheath, a protective component, and a coil assembly disposed within the protective component. The protective component includes a housing, a snap-fit ​​block disposed on the inner side wall of the housing, and a cover plate covering the top of the housing. The coil assembly includes a coil and an iron core, with the iron core disposed within the coil and the coil disposed within the housing. A shielding cover is fitted on the outer side of the coil assembly. The shielding cover includes a cover body and a shielding layer. A shielding layer is adhered to the inner side wall of the cover body, and a metal honeycomb plate is adhered to the outer side of the shielding layer.

[0009] Furthermore, the bottom of the housing is fixedly connected to the top of the sheath, and the bottom sidewall of the sheath is fixed with multiple sets of protruding structures.

[0010] Furthermore, a slot is formed between the snap-fit ​​block and the side wall of the housing, and the snap-fit ​​block on the cover is fixedly engaged with the slot.

[0011] Furthermore, the bottom of the cover plate is interference-fitted to the top of the housing.

[0012] Furthermore, the metal honeycomb panels are arranged in an equidistant array on the shielding layer.

[0013] Furthermore, the cover is disposed within the gap between the housing and the coil. Beneficial effects

[0014] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0015] This invention utilizes a shielding layer structure, employing an adhesive shielding layer. The shielding layer is a conductive rubber structure containing conductive particles evenly distributed within the silicone rubber. Pressure brings the conductive particles into contact, achieving excellent conductivity. This shielding layer effectively shields electronic devices, such as servers, from electromagnetic waves generated during operation. The external metal honeycomb panel structure enhances the structural connection between the shielding layer and the enclosure. Furthermore, the honeycomb structure improves filtering efficiency through its shape.

[0016] The shielding structure in this device can be fixed to the housing after the coil assembly is fixed to the housing. The shielding is fixed by the locking block structure and the groove formed between the locking block and the external structure. It is locked in the gap between the two, which can achieve a fast fixed connection effect. Attached Figure Description
