In the daily operation of a vehicle, power serves as a critical energy source, directly influencing whether the engine can function properly. Within an automobile’s power system, automotive connectors are categorized into distinct types — and this classification allows for targeted sealing measures to be applied across multiple key junctions. Specifically, these measures are implemented between male connectors and vehicle equipment, male connectors and cables, male-female terminals, as well as female connectors and cables.
To guarantee the airtightness of automotive connectors, sealing rings stand out as a widely used solution. Beyond their primary sealing function, they also deliver a fixing effect between different hole positions. This dual role is essential for maintaining the stable operation of automotive equipment and ensuring its waterproof performance during the vehicle’s use. Most sealing rings are manufactured from silicone rubber, a material produced through chemical modification processes involving liquid silicon and solid silicon.
Electronic circuit technology plays a pivotal role in supporting the stable operation of automobiles, particularly in areas like automotive infotainment systems and control systems. To safeguard the reliable performance of these electronic circuits, a variety of shielding technologies have been integrated into automotive manufacturing processes.
These shielding technologies offer more than just protection for a car’s electronic circuits — they also provide anti-interference and radiation-resistant benefits for the vehicle’s components. Additionally, they contribute to ensuring the stable operation of automotive connectors. In the context of automobiles, these shielding technologies can be broadly divided into two main types: internal shielding and external shielding.
When external shielding is used to protect automotive connectors, the common practice involves assembling two identical shielding shells together to form a complete shielding layer. A key requirement here is that the length of this shielding layer must fully cover the entire length of the connector. Furthermore, the shell of the shielding layer needs to feature a sufficient locking plate structure; this structure is critical for ensuring the reliable installation of the shielding layer. Another important consideration is the shielding material itself: it not only needs to undergo electroplating treatment but also requires additional processing to enhance its resistance to chemical corrosion.
