AI Technical Summary
The current automotive waterproof plugs have a fixed hole size, which results in poor sealing when there are fewer wires, posing a risk of leakage.
A waterproof plug body with a vertical orientation and a detachable plug mechanism is designed. The plug mechanism consists of a snap ring, a pad, and a pull ring. The pad fills the gap between the wire harness and the wire hole, and the sealing performance is improved by the snap groove and the sealing protrusion.
It effectively fills the gap between the wire harness and the wire hole, improves the sealing effect of the waterproof plug, prevents water leakage, and enhances the safety of the wire harness.
