New energy vehicle wiring harness, also known as low-voltage wire, is not the same as ordinary household wire. Ordinary household wires are copper single-piston wires, with a certain degree of hardness. Some of them are as thin as a hair, with several or even dozens of soft copper wires wrapped in plastic insulation tubes (PVC), which are soft and not easy to break. Due to the special nature of the automotive industry, the manufacturing process of new energy vehicle wiring harnesses is also more special than other ordinary wiring harnesses.
Here is the content:
l Classification of wire harnesses
l Harness packaging into storage precautions.
l Note when inserting terminals
According to the structure, the new energy vehicle wiring harness is divided into full utilization harness, partial utilization harness, and link system; according to the service mode, it is divided into loss system harness and waiting system harness (see random service system). According to the number of load sources served, it is divided into unlimited load source harness and limited load source harness. In telecommunications systems, the equipment used directly for inter-user communication is mostly infinite load source loss-based full utilization link system, while the equipment used to control the connection process of communication equipment is mostly infinite load source wait-based full utilization system. When the number of load sources is not very large relative to the capacity of the harness, the full utilization system or partial utilization system with limited load sources is generally used.
l Package the new energy vehicle wiring harness strictly according to the packing card requirements and check it according to the quality inspection guide.
l Pack the harness into the packing box, the harness is neatly arranged in the packing box, and the harness label is placed visibly above.
l Different models of packaging boxes require different colors and need to be distinguished.
l Paste the correct outer box label and ALERT label.
l Put the packaged harness into the tray, not mixed with other unpackaged harnesses.
l Pay attention to the packaging of zero box harnesses, especially the label and quantity.
l Inserting the terminal is the process of inserting the branch through the closure tube, sheath, etc., and then inserting the connector.
l Remove the branch from the material rack, pay attention not to exert too much force, make sure the branch cannot touch the ground.
l Visual self-inspection of the branch and terminal, the branch must not have broken skin, terminal crimping no abnormalities, no deformation of the terminal.
l Adjust the connector to the direction of the connector as shown by the visual aid on the wiring board.
l Put the connector into the corresponding fixture.
In the case of raw materials and parts to meet the performance and quality requirements, in the manufacturing process of thenew energy vehicle wiring harness to strictly control the processing quality of each process and the control of the physical quality. Once the car's intelligent type increases the application of wire harnesses, it will cause the number of wire harnesses to increase, taking up more space in the car, increasing the weight of the car itself, reducing the flexibility and safety of the car. The appearance will also cause some impact, so how to reasonably place the wire harnesses to avoid the above problems is also an important issue.
