What are the different types of wiring harnesses?

1, Classified by Function
1. Power harness
The power harness is mainly used for transmitting electrical energy and is an indispensable part of the electrical system. They are usually composed of highly conductive metal cores (such as copper or aluminum) and an outer layer of insulating material, which can withstand large current loads. Power harness is widely used in various devices that require stable power supply, such as household appliances, industrial machinery, automotive electrical systems, etc.
2. Signal wiring harness
The signal harness focuses on transmitting control signals and data information. Compared with power harnesses, signal harnesses have higher requirements for signal integrity, anti-interference ability, and transmission speed. They usually use structures such as shielded wires or twisted pair cables to reduce electromagnetic interference and ensure accurate signal transmission. Signal wiring harnesses are widely used in fields such as communication, computers, and automotive electronic control.
2, Classified by structure 1 Flat wire harness
Flat wire harness, as the name suggests, has a flat cross-section and has the advantages of small size, light weight, easy wiring and fixation. The wires of flat wire harnesses are usually arranged side by side and separated by insulation material layers to achieve parallel transmission of multiple signals. They are widely used in computer internal connections, automotive instrument panels, home appliance control boards, and other occasions.
2. Circular wire harness
The wires of the circular harness are arranged in a circular pattern around the central axis and wrapped in an outer sheath. This structure gives circular wire harnesses strong bending resistance and wear resistance, making them suitable for use in complex environments. Circular wire harnesses are commonly used in applications that require significant mechanical stress, such as automotive engine compartments and industrial equipment interiors.
3, Classified by usage environment
1. High temperature resistant wiring harness
The high-temperature resistant wire harness is made of special high-temperature insulation materials and high-temperature resistant wires, which can work normally in high-temperature environments. They are widely used in high-temperature environments such as automotive engine compartments, industrial furnaces, and aerospace.
2. Waterproof wiring harness
Waterproof wiring harness has excellent waterproof performance and can maintain the stability of electrical connections in humid and wet environments. Waterproof wiring harnesses typically use connectors with good sealing properties and an outer layer of waterproof material to ensure that moisture cannot penetrate into the internal circuit. They are widely used in outdoor equipment, underwater equipment, and occasions that require waterproof treatment.
3. Oil resistant and corrosion-resistant wiring harness
In some special work environments, such as near car fuel tanks, chemical equipment, etc., it is necessary to use oil resistant and corrosion-resistant wiring harnesses. These wiring harnesses are made of special corrosion-resistant materials and sealed structures, which can maintain the stability and reliability of electrical connections in harsh environments such as oil stains and chemicals.
4, Classified by degree of customization
1. Standard wiring harness
Standard wire harness is a wire harness product produced according to industry standards and specifications, with uniform specifications and performance requirements. Standard wire harnesses are widely used in various general equipment and systems, making them easy to purchase, install, and maintain.
2. Customized wiring harness
Customized wiring harness is a wiring harness product designed and produced according to the specific needs of customers. They may have special wire specifications, connector types, sheath materials, and other requirements to meet customers' personalized needs in terms of functionality, performance, appearance, and more. Customized wire harnesses are widely used in high-end equipment, special application scenarios, and markets that require differentiated competition.
5, Other special types of wiring harnesses
In addition to the above types, there are also some special types of wire harnesses, such as flexible wire harnesses, high-frequency wire harnesses, fiber optic wire harnesses, etc. Flexible wiring harnesses have excellent flexibility and bendability, making them suitable for use in situations that require frequent movement or bending; High frequency wire harnesses have the characteristics of low loss and high transmission speed, and are suitable for the transmission of high-frequency signals; Fiber optic cable harnesses use optical fibers as transmission media, which have the advantages of fast transmission speed, large bandwidth, and strong anti-interference ability, and are widely used in the fields of communication and data transmission.
