In the area where the water is splashed in the wet area, such as the engine compartment, in order to avoid plug -in, the plug -in should be placed horizontally (the exit direction of the plug -in is parallel to the body's bottom plate).

In the wet area where there is water, or where the flowing sink flows, it is forbidden to place plug -in and ground terminals

The wet zone buckle band should be used in the form of a pad.

The fixed point of the thread beam in the waterproof membrane on the door sheet metal is greater than 30mm from the waterproof membrane coating boundary to prevent leakage of the waterproof membrane after pushing the waterproof membrane. Enter the car.

The wiring beam at the wheel and the floor needs to increase the corresponding protection. Avoid driving on off -road, sandy roads, or winter ice and snow roads, splashing hard stones, snow and snow blocks to crack the lines.

The front and rear bids should be arranged on the height of the line beam for the fixed position of the plug -in to avoid the waterproof and dustproof protection of the wiring beam, but whether the school check is convenient for assembly.

5) Electrical safety protection

For wire beams, safety is the first place. The safety protection in the design of the wire beam is mainly the following points:

Positive extremes (battery positive electrode, motivation positive poles) must set the insulation plastic protective cover or other protection measures that are not easy to deform, while ensuring that the protection measures are not easy to leave.

The wire beam cannot adopt the same fixed point as the oil pipe and brake management, and cannot be arranged through or cross.

There must be a gap between not less than 20mm between the positive and polarization of the battery and the battery cover or the engine cover to avoid short circuit and cause the battery to instantly large current discharge and cause the battery to explode.

Considering the car collision, the wire beam cannot be squeezed. The cable beam is squeezed and ruptured, and the internal short circuit may instantly cause fire, causing further harm to the drivers and passengers.

When designing, the line bracket must have sufficient relaxation (greater than the minimum length of the wire beam 25mm), so that it is not prestressed to the continuous electrical components. The stretching of the wire beam is too tight, which is easy to cause the line beam fixed point position to be dislated, which causes the distance between the two fixed points to increase instantly, thereby lengthening the line beam to cause the internal connection of the wire beam to pull off/virtual connection, change the wire parameters, and even pull the wire.
