Application classification of wiring harness for automotive wiring harness

Automobile Wire Harness is the main body of the network of automobile circuits, and there is no automobile circuit without wire harness. Wire harness refers to a component that is connected to a circuit after the contact terminal (connector) made of copper is crimped with a wire and cable, and then plasticized to an insulator or an external metal shell. Wire harness industry chain includes wire and cable, connectors, processing equipment, wire harness manufacturing and downstream application industry, wire harness application is very wide, can be used in automobiles, household appliances, computers and communication equipment, all kinds of electronic instruments and meters (drive screen harness), body harness connected to the entire body, the general shape is H-shaped. Automotive wiring harness is the main body of the network of automotive circuits, connecting the electrical and electronic components of the car and making it function, there is no wiring harness there is no automotive circuit. At present, whether it is a high-end luxury car or an economical ordinary car, the form of wiring harness is basically the same, is composed of wires, connectors and packaging tape, it is to ensure the transmission of electrical signals, but also to ensure the reliability of the connected circuit, to supply the specified current value to the electrical and electronic components, to prevent electromagnetic interference to the surrounding circuit, and to exclude electrical short circuit.


Automotive wiring harness is divided from the function, there are two kinds of power cables that carry the power of the driving actuator (actuator) and signal wires that transmit the input instructions of the sensor. Power cables are thick wires that carry large currents (power control cables), while signal wires are thin wires that do not carry electricity (data transmission cables).

Application classification of wiring harness for medical wiring harness

Medical Wire Harness, as the name suggests, is used in medical equipment, medical devices supporting the connection of wiring harness products, is the wire of medical electronic equipment, it can be said that no wiring harness medical electronic equipment can not operate normally. Its wires are made of UL, VDE, CCC, JIS and other certification standards of high quality wire, medical connectors commonly used wire board connector, D-SUB connector, pin bar, aviation plug, etc. The connector brands used are generally TYCO, MOLEX, JST and other international brands. System certification is generally based on ISO13485 medical certification, and most materials also need to have sterilization requirements. Research institution BCC Research survey report pointed out that the global home medical equipment market size annual growth rate continues to rise, medical electronics will become a new growth point for connector applications.Medical wire harness

Medical wiring harness is made of electronic wire cut to an appropriate length according to the drawing, and then the contact terminal (connector) made of copper material is crimped with the wire and cable, and the outer part is plasticized and pressed with an insulator or an external metal shell, etc., and bound with the wire harness to form a component connecting the circuit. Control harness); Medical industry because of the high risk, high precision industry characteristics, its medical device standards are different from the general device standards, if only from the strictness of the standard, medical device inspection standards are the most stringent.



Application of wire harness classification of industrial product wire harness

lndustrial Wire Harness for industrial products, which mainly refers to the electronic cables, multi-core cables, and wiring cables configured with components in the cabinet. It is widely used as one of the most employed wiring harnesses in the cabinets of industrial UPS, PLC, CP, frequency converter, monitoring, air conditioning, and wind energy. There are many segmented products (sensors & industrial control systems; Network communication, temperature control and air conditioning, air conditioning systems, LED and lighting, rail transit, Marine and Marine engineering, renewable new energy, measurement and test equipment, packaging and logistics transmission), covers the most types, there are no too many requirements for certification and scale, Aichie engineering team has more than ten years of experience in this industry. There is also a lot of demand for brand materials, and there are extremely many choices for the supply chain, especially the selection of connectors, and the demand for brands and types is very large.
