In modern electronic devices, the role of wire harnesses (cable harnesses) is very important, mainly reflected in the following aspects:

Power supply: The wiring harness transfers power from the battery or power unit to various parts of the equipment, ensuring that the equipment can operate normally. It provides the necessary power for various electrical components.

Signal transmission: The wiring harness is responsible for transmitting various signals inside and outside the equipment. For example, in a computer, it transmits data signals to components such as the motherboard, hard drive, graphics card, etc. In cars, it transmits sensor signals, control signals, and communication data.

Organization and management: The wiring harness organizes cables and wires according to a certain structure, reducing the problem of disorderly cables and making the internal wiring of the equipment more tidy. This helps simplify the installation process and maintenance operations.

Protection and shielding: Wiring harnesses are usually equipped with insulation and shielding layers, which can protect the internal cables from external environmental factors such as high temperature, moisture, chemicals, etc., while preventing electromagnetic interference (EMI) and signal crosstalk. The shielding layer can ensure the normal operation of the equipment and reduce noise.

Simplify production and maintenance: Standardized and modular wiring harness design can simplify the production process of equipment. They are usually prefabricated, which can reduce manufacturing time and errors. When the online harness needs maintenance or replacement, it can also be quickly located and resolved.

Improving reliability and safety: High quality wiring harness design and materials can enhance the reliability and safety of electronic devices. By reducing the risk of electrical problems or short circuits caused by wiring harness failures, ensure long-term stable operation of equipment.

Reduce volume and weight: Modern wire harness designs tend to be compact and lightweight, helping to reduce the total volume and weight of electronic devices, which is particularly important for portable devices and high-density integrated applications.
