What anti-corrosion requirements should be considered when selecting charging connectors for coastal areas or regions using road salt in winter?
Coastal salt spray environments and winter road de-icing salts both cause electrochemical corrosion on metal components of charging connectors. The following aspects should be prioritized during selection:
1. Terminal plating: Power and signal terminals should use thick plating designs (e.g., nickel underplating + tin/silver top layer), with plating thickness meeting salt spray test requirements (typically ≥500 hours neutral salt spray without red rust), preventing base copper oxidation that increases contact resistance;
2. Housing material: Prefer weather-resistant engineering plastics and avoid easily corroded metal housings; metal decorative parts should use 316 stainless steel or anodized aluminum alloy;
3. Sealing design: Interface sealing rings should use salt-spray-resistant, aging-resistant silicone or fluororubber materials, ensuring IP65 or higher protection to prevent salt-laden moisture from entering;
4. Cable jacket: TPU jackets outperform ordinary TPE in hydrolysis and salt-spray corrosion resistance; TPU cables are preferred in highly corrosive environments;
5. Certification requirements: Key components should be verified through salt spray testing (IEC 60068-2-11 / GB/T 2423.17).
DEGSON charging connectors use thick-plating terminal technology, and their housings and seals are validated for salt spray aging, meeting long-term use requirements in coastal and highly corrosive environments.
