Similarly, if the inline point of the wire harness and the connection part of the plug-in are not well sealed, it will also cause water ingress and lead to electrical failure. Therefore, we define wet area sealing as sealing the electrical functional parts and wiring harness connection parts in the wet area of the vehicle to isolate the entry of water and ensure the normal and reliable protective operation of the electrical function.
There are two main ways for the water to enter the electrical system: one is to rely on the gravity of water to penetrate into the electrical module or indirectly into the electrical module through the connector, the wiring harness inline point, and the wiring harness grounding point; the other is due to the siphon phenomenon. Molecules enter the electrical module through the gaps between the stranded copper wires.
