What kind of environmental performance should the connector have?

I. What kind of environmental performance should the connector have? The same object in different environments will have different technical performance, therefore, the evaluation of an object is good or bad, to see how much it can withstand environmental conditions is also an important indicator. For the connector this electronic engineering field is familiar with the components, it is used in all corners of our production life, to meet the needs of the application in a variety of complex and harsh environments, its environmental performance is particularly important. Temperature can change the physical state of the object, it is a very strong factor affecting the effectiveness of the connector, due to different seasons, geographical differences, the ambient temperature will be a lot of difference, and the connector in the connectivity of the two components, the current through the heat will also lead to a rise in temperature, which adds up to the operating temperature. A good connector within the metal components should be able to maintain the physical state within a certain temperature does not change, so as to ensure its high performance. It is often specified that it should be able to withstand temperatures as high as 200 degrees and as low as minus 65 degrees. The effect of humidity on connectors is really the effect of water. Because water is corrosive to metal components, but also has a certain conductivity, can reduce the insulation, so the connector component materials must be selected to minimize the impact of water. Usually specified, the connector should be able to 90% -95% relative humidity, 40 degrees or so in the temperature, at least 96 hours of normal operation. Salt spray is moisture containing salts, it can produce chemical corrosion of metal components, affecting the electrical performance of the connector. It is usually stipulated that it should be able to work continuously for at least 48 hours in a salt spray environment made artificially with a specific sodium chloride solution. Vibration and shock mainly affects the connector's degree of robustness and the reliability of the electrical contact, usually according to the environment in which the connector is applied, according to the relevant parameters to simulate the vibration and shock of the environment to test its performance. Liquid impregnation is similar to the impact of water, compared with humidity, the performance of the surrounding water is large, the role of a short period of time, usually through the examination of the sealing to assess the ability to resist liquid impregnation.
