Product details

Wire harness is a wiring component that connects each electrical device in the automobile circuit, and is composed of insulating sheath, terminal block, wire and insulating wrapping material.

  Wire harness is an important part that connects each electrical and electronic equipment in the car, which transmits electrical signals between power supply, switch, electrical and electronic equipment, known as nerve transmission and blood supply, and is the carrier of electrical signal control for the car. Automotive wire harness is the main body of the network of automotive circuits, without the harness there would be no automotive circuit. [1] In order to facilitate installation and maintenance, and to ensure that the electrical equipment can work under the most adverse conditions, the different specifications and colors of the wires used in the electrical equipment of the car are combined into one through reasonable arrangements, and the wires are bundled into a bundle with insulating materials, which is both complete and reliable.

  Choose the car wire harness connected to the car switches, electrical appliances, sensors, power and all electrical and electronic equipment, all over the car's engine compartment, cab and outside the cab. Due to the characteristics of the use of the car itself, such as: it must be repeated through the heat, cold, bumpy and other harsh environmental and use conditions, it determines the technical requirements of automotive electrical and electronic equipment, so the main technical requirements of the automotive wire harness: the correctness and continuity of the circuit, the ability to resist vibration, shock, alternating heat and humidity, high temperature, low temperature, salt spray and industrial solvents. [2] 1) wire cross-sectional area of the correct choice of electrical equipment in the car according to the size of the load current to choose the cross-sectional area of the wire used. Long-time work of electrical equipment can be selected from the actual load capacity of the wire 60%; short-time work of electrical equipment available wire actual load capacity of 60%-100%. 2) The choice of wire color code in order to facilitate identification and maintenance, the wire bundle of wires using different colors. In order to mark the convenience in the circuit diagram, the color of the wire are expressed in letters, the color of its representative in each line diagram are attached.
