What are the common main causes of corrosion in aviation connectors, as described by hardware enterprises?

Recently, Wofu Hardware happened to learn about a connector application designed for marine environments, so we’ve gathered some relevant information and would like to share it with everyone. For connectors that are immersed in seawater for extended periods, the inner and outer surfaces of the metal housing are prone to corrosion by seawater, which can compromise their watertight performance.

We’ve already touched upon the basic knowledge of corrosion mechanisms in previous articles. Now, let’s move on to practical applications and analyze specific cases in detail, thereby deepening our understanding.

This is a typical waterproof connector design, comprising several key structural components of the connector: the housing, the insulating core, and the contact seal. To ensure the robustness and reliability of a waterproof connector, the housing material is typically made of metal—common materials include stainless steel, copper alloys, or titanium alloys. The sealing between the plug and socket is achieved using sealing rings, with two common sealing methods: radial sealing and end-face sealing.
