2) Wire beam perforation and installation of rubber cover

When the thread beam is over -perforated, the often made mistakes are that the size of the holes only considers the thickness of the wire beam, and ignoring the plug -in on the wire beam also needs to pass through the hole. This is a very simple logic, but it is often committed by beginners. mistake.

The sheet metal opening hole is not a casual point. The process of sheet metal openings needs to be considered. The requirements of the sheet metal holes during the installation of the wiring rubber cover. Generally speaking, there are the following requirements:

The diameter with the largest diameter of outsourcing must be less than the diameter of the sheet metal hole. The usual requirements are that the diameter of the sheet metal hole is at least three times the maximum size of the plug -in. This requirement is also applicable to the wiring beam through the closed cavity, such as the inner and outer plate of the tail door, the cavity of the cavity of the inside and outside of the side, etc., and the diameter of the cavity space cross section is 1.3 times more diameter of the cavity.

The corresponding pellet size corresponds to the rubber parts is correct and the thickness of the material is correct. The coordination of the rubber and sheet metal parts is greater than 1mm, less than 2mm;

The radius of the hole along the hole is greater than the sheet metal surface within 6mm of the blocking hole must be smooth to ensure the confinement.

3) The installation of the plug -in

The connection is an important electrical parts on the wire beam assembly. When designing the beam design design, you should pay attention to the installation of the connection plug -in. There are mainly the following requirements:

The line beam at the end of the plug needs to reserve a certain length in order to facilitate the plug -in of the plug.

The reserved length of the plug -in plug -in, the targets that focus on: combined instrument, switch panel, air -conditioning panel and audio system and display screen connect to the instrument board beam connection, the four -door switch wire beam and the top lamp on the interior ceiling And the switching wire beam, in addition, the wire beam plug -in on the sub -meter, the wiring plug -in plug -in and the wiring beam docking plug -in in the seat also need to be reserved.

According to the installation depth of the electrical device, the location of the socket, the direction of the socket opening, and the rear space after the electrical component assembly, according to the convenience of operation, appropriately increase the reserved length of the connector on the line beam.

Reserve length L = Electrical device Installation depth H+Electric Device Panel width 0.7b+100 (mm),

Among them: After the electrical device installation depth H-refers to the assembly of the electrical device, the distance from the external decoration surface to the internal electrical device is connected to the socket.

When the length is reserved, special attention should be paid to the abnormal noise and cutting of the wire beam. You can avoid causing damage by increasing the exterior anti -cutting parcel and the surrounding sharp parts to increase the anti -cut glue strip.

Due to the differentiation of the vehicle, the cable beam branch that is not currently used during assembly needs to be bundled separately and fixed on the trunk line or bracket. The minimum curved radius during the bundle cable beam cannot be twice less than 2 times the diameter of the wire beam.

To ensure that the plug -in installation space is sufficient, in the interpolation direction of the plug -in, there must be space with more than two times the space of the plug direction.

The wiring beam insertion should be arranged in a place where it is easy to find, as much as possible at the place where the tentacles can be, and the place where it is easy to operate by the hand and the tools is easy to operate.

The connection plug -in needs to be fixed, and the fixed hole of the plug -in needs to be anti -rotation, which is convenient for the plug -in fixation.

The iron terminals and motors such as the wire beam should be designed with anti -rotation.
