In what environments are heavy-duty connectors used?

I. Heavy-duty connectors in what environment?1, high temperature electronic connector metal materials and insulating materials determine the connector's operating environment temperature, high temperature will destroy the edge material, resulting in lower insulation resistance and withstand voltage; for metal, high temperature will make the contact vice lose elasticity, accelerate oxidation, resulting in coating deterioration. Usually the ambient temperature is -55 ~ 100 ℃, special occasions may be higher. 2, humidity relative humidity greater than 80%, is the main cause of electrical breakdown, humid environment so that the insulator surface absorption and diffusion of water vapor, easy to make the insulation resistance is reduced to below MΩ. Prolonged exposure to high humidity will cause physical deformation, decomposition, escape, resulting in respiration, electrolysis, corrosion, and cracks. Especially the electronic connectors outside the equipment, often to consider humidity, water seepage, pollution and other environmental conditions, in which case, sealed connectors should be used.3, rapid temperature change rapid humidity change test is to simulate the actual use of electronic connectors in a cold environment to a warmer environment, or to simulate the rapid change in the ambient temperature of a spacecraft or a detector, a sudden change in temperature may lead to the appearance of the insulation material Cracks or delamination. 4, thin air in the thin air at high altitude, the plastic puts out gases to contaminate the contact pair, corona tends to increase, the voltage resistance is reduced, the circuit produces a short-circuit failure, when the heavy-duty connector reaches a certain value at high altitude, the performance of the plastic will deteriorate, so the non-sealed connector in the high altitude when used, it is necessary to derate the use of the 5, corrosive environments according to the different corrosive environments in the electronic connector, choose the appropriate Metal, plastic, plating structure of the connector, such as salt spray environment used in the connector, if the metal surface is not corroded, the performance will deteriorate rapidly. In the environment containing a considerable concentration of SO2, it is not recommended to use silver-plated contacts on the connector, in the field of hot and humid, mold is also an important issue.
