1) The direction control of the wire beam

During the three -dimensional layout of the online beam, we should fully consider the uncontrollability of the line beam direction, combined with the actual vehicle assembly experience, and evaluate the reliability of layout. The requirements of the reliability guarantee of the wiring beam segment control are:

The spacing between the wire beam and the two fixed points should not be too large. It is controlled at about 300mm. In harsh environments such as mud, the fixed distance of its tie must not be greater than 150mm.

When the lines are arranged with a straight corner corner, both sides of the right corner need to increase the fixed point. When the corner of the blunt corner is controlled, control according to the straight line distance to avoid the sharp corner turning point.

The thread beam branch point should be as close to the fixed point of the wire beam trunk as much as possible, and the distance is within 100mm.

The fixed buckle of the wiring beam should match the size of the sheet metal holes, the thickness of the sheet metal, and the specifications of the convex welding thread. At the same time, it is necessary to avoid directly bearing the cable beam gravity.

The layout of the wiring beam should be along the side and the groove to prevent the wire beam from directly undergoing pressure.

2) The gap control of the wire beam

In order to prevent damage to the cable beam, the wiring beam should avoid the edge of the sharp sheet metal, the edge of the surrounding parts, and the installation holes of other parts, especially the beam. The requirements of the gap between the wire beam are:

In addition to the parts of the fixed wire beam, the gap between the wiring beam and the peripheral parts (non -sharp edges) is above 6mm (inclusive).

Consider the effects of the installation of other parts on the wire beam during the layout of the wire.

When the wire beam is fixed on the two parts with relative motion, the length of the cable section should be greater than the displacement length between the two components, and the minimum value is 25mm.

The minimum distance between the wire beam and the motion component should be greater than 25mm, and the gap between 7mm (inclusive) or more from the motion package is more than 7mm (including).

In the wiring beam in the vibration area, the wiring beam should be kept within 100mm on the back of the plug -in.

In addition to the basic physical protection mentioned above, such as the interference between the wiring beam and the surrounding parts, the online beam layout also needs to do the safety protection of electrical properties, such as waterproof, dustproof, electromagnetic interference, and temperature control.
