I believe that the terminal wire harness we see at ordinary times are finished products, but in the process of processing and production of wire harness, the requirements of wire harness are quite strict, the following small make up to introduce to you, how strict are the requirements of terminal wire?

What are the requirements for terminal wiring harness processing?

1. After the wiring harness is completely made, it needs to be fully inspected by the quality Department. If the unqualified products are not in place, they should be reworked.

2. After the terminal is pressed, it is necessary to wear the rubber shell. This step can not be automated production, but can only be manual.

3. For other complex wiring harnesses, casing and heat shrinkage may also be required.

4. Incoming materials should be correct, raw materials should be inspected and production scrapped from the source.

5. After confirming the material, you need to cut the wire and hit the terminal, and you need to do the first piece. Subsequent production and inspection should take the first piece as the standard.

Terminal wire is mainly used for the connection between the electronic equipment internal circuit, it can transmit current or signal in the electrical equipment, ensure the normal use of electronic equipment without terminal wire! At present, there are three standards for the mainstream terminal connection wire in China: UL standard, 3C standard and VDE standard. The internal conductor of the terminal connection wire is generally tinned copper or bare copper. The following is the analysis of terminal connection wire structure and composition for you:

1, the jacket raw materials should mainly use heat-resistant PVC jacket material imported from Japan.

2, terminal connection wire barrier layer using horizontal coil or woven ф 0.1mm and above wire diameter tinned soft copper wire, to improve the cable anti-disturbance, anti-noise ability.

3, insulation materials are mainly imported from Japan with high function heat-resistant PVC insulation material, semi-hard, soft, hard three categories;

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