The salt and mist environment mainly refers to the use of medical device connectors and electric vehicle connectors and the application environment underwater. The salt mist environment under normal circumstances refers to the salt mist environment formed by 5%salt solution. Usually this environment can effectively evaluate the equipment or components that are directly exposed to the environment such as salt. The exposure time is between 24 hours and 48 hours.

Salt and fog testing is usually used in the underwater environment and is usually used to evaluate the corrosion resistance of the metal connector shell (such as verifying the corrosion protection effect of nickel plating on the surface of the zinc -co -pressure casting. The performance of the part is effective to determine the shell sealing.

Salt and fog tests are sometimes used in the assessment of car connectors. When cars or trucks walk, the location of these board connection connectors may be exposed to the splash water on the ship. Salt will be applied to accelerate snow melting. These connectors generally need to perform salt fog tests to verify its corrosion resistance. The verification standards also test the reliability of the contact resistance, rather than evaluated by checking the appearance. Many times these connectors should be used with the sealing ring to improve its salt -resistant performance.

The basic properties of the connector can be divided into three categories: mechanical performance, electrical performance and environmental performance.

1. In terms of mechanical properties connected, the plug -in force is an important mechanical performance. The plug -in force is divided into insertion power and outbound force (also known as separation force). The requirements of the two are different. In the relevant standards, there are insertion power and minimum separation power regulations, which shows that from the perspective of use, the insertion force should be small (thereby the structure of low insertion LiF and no insertion force ZIF), and if the separation force is too small, then the force is too small, then then It will affect the reliability of contact.

Another important mechanical performance is the mechanical life of the connector. Mechanical life is actually a durability indicator, which is called mechanical operation in the national standard GB5095. It is a cycle with one insertion and one -time pull out, and whether the connector can complete its connection function (such as contact resistance values) as a basis for judging in a specified plug -in loop.

The plug -in and mechanical life of the connector is related to the coating quality (sliding friction coefficient) and the size accuracy (alignment) of the contact part of the contact site (positive pressure) contact site.
