What are the requirements for electronic wire harness processing? I believe that the terminal wire harnesses that you usually see are finished products, but in the process of wire harness processing and production, the requirements for wire harnesses are quite strict. Let me introduce to you below. How strict are the requirements for terminal wires?

  What are the requirements for electronic wire harness processing? I believe that the terminal wire harnesses that you usually see are finished products, but in the process of wire harness processing and production, the requirements for wire harnesses are quite strict. Let me introduce to you below. How strict are the requirements for terminal wires?

  1. After the wiring harness is completely made, it needs to be fully inspected by the quality department. If it is unqualified or not in place, the product will be reworked.

  2. After the terminal is crimped, the plastic shell needs to be worn. This step cannot be automated, but can only be done manually. It also needs to be compared with the first piece. The production line staff must be trained to ensure that the rubber shell is worn correctly and in place, and cannot fall off.

  3. If it is other complicated wiring harness, it may need to wear a sleeve, heat shrink, etc.

  4. The incoming materials must be correct, and the raw materials must be inspected to prevent production scrap from the source.

  5. After confirming the material, it is necessary to cut the wire and make the terminal. It is necessary to make the first piece. Subsequent production and inspection must be based on the first piece.

  The above is the quality assurance process in the process of electronic wiring harness processing. Every step is very careful to prevent the terminal wire harness with quality problems from flowing into the next program. You should understand the requirements of some terminal wires.

  The terminal wire is mainly used for the connection between the internal circuits of electronic equipment. It can transmit current or signals inside the electrical appliance, ensuring the normal use of electronic equipment is inseparable from the terminal wire! At present, there are three standards for the mainstream terminal connection wires in my country: UL standard, According to 3C standard and VDE standard, the internal conductor of the terminal connection wire is generally tinned copper or bare copper. The following editor will analyze the structure and composition of the terminal connection line for you:

  1. The raw material of the sheath is mainly heat-resistant PVC sheath material imported from Japan.

  2. The shielding layer of the terminal connecting wire is made of tinned annealed copper wire with a wire diameter of Ф0.1mm and above, which is rolled or braided, to improve the anti-interference and anti-noise ability of the cable.

  3. The insulating material mainly adopts high-performance heat-resistant PVC insulating material imported from Japan, which is semi-rigid, soft and hard;

  4. The conductor of the terminal connection wire is tinned annealed copper wire with European and American wire gauge 14-30AWG, the terminal connection wire and the electric annealed copper wire with a cross-sectional area of ​​0.3mm2-2.0mm2. There are three conductor methods: stranded conductor, OS-1 (TCW) conductor, and solid conductor.
