Wiring Harness Waterproof and Dustproof Protection
Waterproof and dustproof protection is often considered in the wiring harness layout process. For this point, the wiring harness layout mainly includes the following aspects:
● The wiring harness passes through the sheet metal, and a drip point (above 75mm) needs to be set to prevent external water or other liquids from flowing into the body through the wiring harness, or under the influence of the siphon effect, the water may flow into the cab connector along the wiring harness .
● In areas where water may splash in wet areas, such as the engine compartment, in order to prevent water from entering the plug-in, the connector should be placed horizontally and fixed in the design (the direction of the plug-in outlet is parallel to the body bottom plate).
● It is forbidden to place connectors and grounding terminals in places where there is accumulated water in wet areas, or where water is flowing in the sink.
● Wet area snap ties should be in the form of gaskets.
