AI Technical Summary
The existing seal is prone to water entering the wiring harness due to the siphon effect when it rains, affecting its use.
A novel sealing plug was designed, comprising a columnar sealing plug, a positioning disc, an annular protrusion, and a flow guide groove. The trapezoidal positioning disc reduces the contact area between the sealing plugs, and the flow guide groove facilitates rapid drainage. Combined with a waterproof ring, it prevents water from entering.
It effectively prevents the siphon effect, reduces sealing blockage and adhesion, ensures the wire harness is dry, and improves the reliability of use.
