With the rapid development of automotive technology, there are more and more electronic configurations on the vehicle, and harnesses as power and signal transmission channels are becoming more and more complex. Today's car lightweight technology is strongly promoted. As a small and essential automotive component, automotive wiring harnesses also face the demand for lightweight. How can we achieve the goal of harness lightweighting on the basis of guaranteeing function and reliability satisfaction? Let's analyze:

The complete wire harness assembly mainly includes: various wire harness accessories such as wires, connectors, wrapping materials, rubber caps, and cable ties. In order to achieve the goal of lightweight harnesses, the weight of these components can only be considered and designed in various aspects.

Based on past experience, reasonable harness layout design, proper wiring principle design, and lightweight selection of harness wrapping materials are the most commonly used and effective design methods for automotive wiring harness designs.

(1) Reasonable layout and optimization of wiring harness arrangement: The most direct and most effective way to reduce the weight of the wiring harness is to reduce the length of the wire used in the loop by rationally arranging the wiring harness, the location of the power distribution, and the optimal placement of the electrical equipment.

(2) Principles Starting from the root, tapping the potential of the roots: Establishing the basis for development, excellent principle design ensures that the wiring harness is simple and lightweight from the root.

(3) To improve the environment and reduce the weight of the wrapping material: a good harness installation environment is safe and worry-free, allowing the harness to be lightly loaded.

The role of the wiring harness is to connect the signal and communication between the power supply and the electrical appliance, the ground and the electrical appliance, and each electrical appliance. As we all know, a straight line is the shortest path to connect two points. However, the layout of the wiring harness due to the layout of the aesthetics, fixed reliability considerations, and the surrounding environment of small factors may allow each loop in the wire harness, each wire is connected in a straight line arrangement, and even almost all loops can not achieve straight connection. The so-called reasonable wiring layout design is through our arrangement so that the majority of loops in the wiring harness detours, in order to shorten the loop length and reduce the amount of wire.
