From the application purpose of the car connector, want to ensure that the vehicle can drive better, we can divide the reliability of the connector into the connector in the use of the sealing, the car in the driving fire performance, at the same time in the vehicle, the connector can also show the shielding performance and temperature control performance. Usually when talking about the sealing of the car connector, the car is not only for the water sealing performance.

In this field, IP67 is the prevailing management system in the world today, and this standard is also a relatively high level in the current car closed industry. Although the waterproof design requirements are different in different parts of the vehicle, many vehicle manufacturers will choose IP67 to ensure the airtight performance of their vehicle connectors.

In the running of the vehicle, the power supply is a very key source of energy, not only related to the normal operation of the engine, and everyone in the process of driving, also often involved in the application of the power supply. Therefore, in the vehicle power system, the car connector will have different divisions, between the male connector and equipment, between the male connector and the cable, between the male and the female connector, and between the female connector and the cable have a certain closure measures can be implemented.

In the realization of the sealing performance of the automobile connector, the sealing ring is a common tool. This tool can not only achieve the fixed effect between different holes, but also achieve the sealing effect. It can not only ensure the stable operation of automobile equipment, but also ensure the waterproof performance of automobile equipment in the work. The sealing ring in the production of most will use silicone rubber this material, this material is made by liquid silicon and solid silicon after a certain chemical change.

Now in the process of car use, electronic circuit technology is an important aspect of the automobile industry, not only in the driver's entertainment, and including the driver in the driving of the car control system, electronic line technology in the stability of the vehicle has played an important aspect. In order to ensure the stable work of electronic circuit technology, many shielding technologies are applied in the production of automobiles.

These shielding technologies not only play a protective role in the electronic circuit of the vehicle, but also play an anti-interference and anti-radiation ability in the components of the vehicle, in addition to the stable work of the car connector can also play a protective effect. These shielding technologies can be divided into internal shielding and external shielding in automobiles.

When an external shield is used to protect an automotive connector, two identical shielding shells are usually assembled together to form a shielding layer, and the length of the shielding layer can cover the entire length of the connector. The shielding shell must be equipped with enough lock plate structure to ensure reliable installation of the shielding layer. In addition, the shielding materials used should not only be treated by electroplating, but also be treated to prevent chemical corrosion.
