3 Inspection technology of car lines and assembly process and production process

Based on the chaotic layout of the existing engine wire, the maintenance process cannot distinguish between line directions. The bandaging is simple, easy to wear, and poor waterproof performance. Relevant construction personnel have developed an electric vehicle low -voltage power control wire beam assembly, which are specific assembly processes, as shown in Figure 2.

This engine wire beam assembly mainly includes: wire beam 12 and the waterproof electric spray system connector connected to the wire beam 12 1. OBD diagnostic connector 3. Waterproof body interface connector 4. Waterproof early advanceer sensor connector 5, waterproof waterproof, waterproof waterproof, waterproof, waterproof Oil and water separator connector 6. Waterproof Entrance Control valve connector 7. Waterproof speed sensor connector 8. Waterproof oil and oil -proof solenoid valve connector 9. The throttle sensor connector 10, waterproof temperature sensor connector 11, of which the engine wire beam assembly The OBD diagnostic connector 3 is installed in the engine compartment, and the connectors and the wiring beam 12 are connected through the wire. In this way, the T -type wiring on the line 1 has three -way sleeve 2 respectively, and then the three -way sleeve 2 card connection fixed target is achieved. Because the connector is moved to the engine compartment, it is easy to find and repair; the use of various waterproof connectors to prevent the connector from getting water, oily oxidation, or function failure; Convenient maintenance; the vibration and mutual wear of the cable beam during driving through the addition of three -way tubes. It can be seen that compared with the existing engine wire beam, the new engine wire beam assembly is more beautiful, easy to repair, and greatly improves the safety, waterproofness and durability of vehicles. Show in Figure 3

One side of the three -way sleeve 2 is set to use the elastic card head 21 of the three -way sleeve 2 card on the side wall of the engine cabin. Therefore, the elastic card head 21 is equipped with a shield 22. There is a spring 23 between the body and the ontology of the three -way tube 2, and the springs 23 resistance to the elastic contact with the tail of the elastic card head 21. In order to further facilitate the inspection and installation of the production process of the car beam, the waterproof body interface connector 4. Waterproof early -advance device sensor connector 5, waterproof oil and water separator connector 6, waterproof early control valve connector 7, waterproof speed sensor connector connector 8. The accelerator sensor connector 10. The side of the waterproof water temperature sensor connector 11 is set with a fixed buckle, and the fixed buckle is the same as the structure of the elastic card head 21 on the three -way sleeve 2. This is because the elastic card header 21 is also installed on the reason for shields and springs. In this case, the car wire beam assembly can simultaneously realize the size, appearance, and bandage of the production process, thereby improving the scientific rationality of the design and use of the car beam assembly.

4 Conclusion

In summary, the carline beam assembly process and production process inspection technology can be optimized and controlled by new car line beams. It turns out that after the above device is used, it not only improves the efficiency of maintenance inspection, but also prevents the problems of various connectors from the problem of water oxidation or function failure. To this end, researchers should act on practice, thereby improving the overall effectiveness of the car wire beam assembly production.
