Now that cars are in use, electronic circuit technology is an important aspect in the automotive industry, not only in the driver's entertainment, but also in the control system of the car when the driver is driving. Electronic circuit technology plays an important role in the stable work of the car. In order to ensure that the electronic circuit technology can work stably, people now apply a lot of shielding technologies in the production of automobiles. These shielding technologies not only play a protective role in the electronic circuit of the car, but also have anti-interference and anti-radiation capabilities in the components of the car. In addition, they can also protect the stable operation of the car connector. These shielding technologies in automobiles can be divided into two types: inner shielding and outer shielding.

When using outer shielding to protect automotive connectors, two identical shielding shells are usually used to assemble together to form a shielding layer, and the length of the shielding layer can cover the entire length of the connector, and the shielding shell should also ensure that There are sufficient locking plate structures to ensure the reliable installation of the shielding layer. In addition, the shielding material used must not only be treated by electroplating, but also be treated to prevent chemical corrosion.
