AI Technical Summary
In existing self-cleaning contact devices, the external brush structure is prone to wear on the plug surface coating under equipment vibration, resulting in poor contact and affecting the reliability of equipment operation.
The air chamber and piston plate are designed for air-solid coupling, and the brush head cleaning action is triggered only during insertion and removal. The air pressure difference drives the rubber rod to push out the brush head, realizing the cleaning mechanism triggered by insertion and removal, thus avoiding continuous friction.
It effectively avoids coating wear, reduces contaminant intrusion, improves plug lifespan and reliability, and ensures cleaning precision and equipment stability.
