Why do connectors corrode? What factors can cause connector corrosion?

When a connector is corroded, the service life can be shortened and it can also cause circuit failure. So under what circumstances will connectors be corroded and what are the main factors? Huichengyuan connector manufacturer will answer for you:

Electrical corrosion of connectors is usually caused by oxidation or galvanizing. Oxidation occurs when the metal of the electrical connector combines with atmospheric oxygen to form a metal oxide. Since most oxides are not good electrical conductors, the oxide coating will limit the flow of electrical current, which will be damaged by electrical corrosion due to environmental influences. Therefore, it is necessary to observe the specific situation of the electrical connector in time, and replace it immediately if excessive oxidation is found to ensure the safety of the machine.

In harsh environments, the main cause of connector failure is electrical corrosion. In the present reaction, different metals release or collect electrons in the presence of an electrolyte, usually water. The ions formed by electron transfer slowly leach out of the material and dissolve it. Water and other corrosion-promoting liquids and gases get into gaps in wires, insulation, plastic housings, and pins and can cause connector corrosion. Additionally, lubricants and coolants needed for proper operation of automated assembly lines can corrode plastic insulation.
