When agricultural machinery is idle for 6 months (winter), how to store connectors to prevent aging?

A: Before storage, wipe the surface of the connector with a dry cloth (to remove mud, water and pesticide residues), apply a small amount of anti-rust oil (such as petroleum jelly) to the contacts, and then put on a dustproof and waterproof cap. The storage environment should be dry (humidity <60%) and normal temperature (5~25℃), avoiding direct sunlight (to prevent aging of the plastic shell). Before next use, wipe the contacts with alcohol cotton pads to remove anti-rust oil and ensure stable signal transmission.
