How To Prevent Heavy-duty Connectors From Being Corroded

Why does 12v heavy duty connector corrode?

heavy duty crimp connectors is a connector used by many manufacturing companies in industrial production processes. heavy duty waterproof electrical connectors is also frequently used. Different corrosion conditions exist, one of which is electrochemical corrosion.

Electrochemical corrosion is accelerated corrosion caused by the contact of a metal or alloy A with a more chemically inert metal in the same electrolyte. In bimetallic contact structures, this form of corrosion is one of the most severe degradation effects. Galvanic corrosion will occur whenever different metals coexist in a solution containing salt ions.

The conditions for electrochemical corrosion are as follows:

Materials have different surface potentials. Commonly used electrolyte 3. Commonly used current path.

For example, the copper-aluminum connection in heavy duty connector produces alkaline aluminum hydroxide, which, under the action of electrochemical corrosion, will volatilize hydrogen gas, leading to a significant reduction in contact area. Severe corrosion can cause mechanical failure. In practical applications, we can also find that in heavy duty electrical connectors, screws and copper contacts are more easily corroded. A crucial factor in electrochemical corrosion is humidity. Humidity is key to the amount of electrolyte used. If the electrolyte is not completely depleted, electrochemical corrosion will not stop. Therefore, in heavy duty power connectors, it is necessary to improve the protection level of the product, or to use auxiliary contact elements and transition gaskets (with added grease or lubricant) to reduce the impact of humidity on the product.

Therefore, manufacturers and customers of heavy duty connector 24 pin need to have expertise in electrochemical corrosion to achieve better and smoother production.
