I. What are the considerations for power connector sealing program? Power connector low-frequency non-sealing is widely used in military electronic equipment, and its reliability directly affects the normal operation of the equipment. When the humidity of the surrounding air is close to saturation, or due to the metal and the environment of low-temperature objects for heat exchange, the metal surface is prone to condensation, resulting in a decline in electrical connector insulation. Atmospheric nitrides, sulfides, and water vapor combined to form a salt solution on the metal surface to form electrolytic corrosion. When the metal surface plating density is not high present more pores, for the salt solution electrolytic corrosion to provide a microcell site, gold plating and intermediate plating potential difference is greater, the more serious electrolytic corrosion. Military electronic equipment working environment is complex and variable, low-frequency non-sealed electrical connectors own sealing grade is not high, high temperature, humidity, salt spray and other harsh factors infringement leads to frequent electrical connector failure. At present, some of the electrical connector sealing structure design, improve the reliability of the power connector in the humid environment. For equipment, the electrical connector sealing upgrade and replacement work involves a wide range of difficulties.
