How to choose a good harness for terminal wire processing?

In the processing of terminal wire, the selection of raw materials will directly affect the quality of the product, so this link is very important, a finished wire harness is composed of wire, insulation sheath, terminals and wrapping materials. As long as you understand these materials, you can distinguish between good and bad harnesses.

1, the selection of wrapping materials: harness wrapping to play a wear-resistant, flame retardant, corrosion-resistant, avoid interference, reduce noise, beautify the appearance of the effect of the wrapping materials can be selected tape, corrugated pipe, PVC pipe, etc. 2, the selection of materials for terminals: terminals with raw materials for the copper is mainly made of brass and bronze, during which phosphorus copper accounted for the proportion of the larger, and other, according to the different needs of the selection of different coatings. 3. Harness wire selection: according to the corresponding wire materials; 4, insulation jacket selection: jacket materials commonly used mainly PA6, PA66, ABS, PBT, pp, etc., according to the actual situation in the plastic guess to increase the flame retardant or enhancement of materials to achieve the purpose of enhancing or flame retardant, such as increasing the glass fiber enhancement and so on. Because of the increasing number of electronic control devices, the number of connecting wires is inevitably an increasing trend, to ensure the correctness and reliability of the wire connection, the terminal line plays a very important role. Terminal line is a harness with a socket, all the sensing terminals are used in special interfaces, control computer ECU and all external parts of the interface are through the ECU on the articulator, and the signal transfer in the wiring harness is also the use of the line articulator. Terminal line in addition to the device has a convenient, accurate wiring, in the use of the problem is often presented, and the most common problem is poor contact and then lead to "network" signal transmission suspension, which directly affects the normal play of the electronic control of the car's outstanding features.
