Production Method
When making the RCA lotus head signal line
Red line Black line synthesis 1 share is positive, green line White line synthesis 1 share is negative. The copper shielded metal mesh is connected to the negative stage of the input end, and the metal mesh at the output end is not connected.
When making a USB2.0 cable, the following figure is shown:
1. Pin name: VCC Description: 5V voltage Wiring color: red
2. Pin name: D- Description: Negative data line Wiring color: white
3. Pin name: D Description: Positive data line Wiring color: Green
4. Pin Name: GND Description: Ground Wiring Color: Black
5. Shielding shell
What is a real silver plated wire?
The wire has silver plating and tin plating. Pay attention to the difference. The silver-plated wire shines brightly. The tin plating is slightly dim. The price and quality are very different. The silver plating wire will be dark and the color will be dark, but the tinned wire will not. meeting. The core is made of 4N copper-plated silver, and the coating is thick, silver-white and bright, and non-common silver-plated wire is comparable.
The red and black wires inside the wire are twisted together, and the green and white wires are twisted to increase the anti-interference ability and improve the sound quality.
In this way, not only can some electromagnetic wave interference from the outside world be resisted, but also mutual interference between multiple pairs of twisted wires can be reduced. Twist the two insulated wires together, the interference signal is consistent on the two twisted wires (this interference signal is called common mode signal), and the common mode can be used in the differential circuit receiving the signal. The signal is cancelled, thereby extracting a useful signal (differential mode signal).
What is brass or copper?
Brass is an alloy of copper and zinc. Copper is a pure copper-copper alloy. It is called copper because it is red after oxidation. The cost of copper is two times more expensive than brass alloy raw materials.
The resistivity of pure silver is 165, followed by the resistivity of copper 175. In fact, the resistivity of pure gold is not low, and the resistivity of brass is about 10 times that of copper. The conductivity of sterling silver is 5.7% higher than that of copper, and the cost is much higher. The conductivity of copper is only a little worse than that of pure silver, but the price is several times cheaper. In terms of performance price, copper is very good. s Choice. This product is copper, pay attention to the real 4N copper, not false.
What does 4N 5N 6N 8N mean?
For example, 99.998% pure copper is called 4N copper, 99.9998% copper is 5N, and a few 9 means there are several N. Why is it so expensive when it is high in purity? Because the cost of metallurgy to improve purity is disproportionate. To smelt 6N copper, the value of 6N is equal to that of sterling silver. If it continues to be purified, When arriving at 8N, the value of this 8N OFC copper is equal to the price of gold equal to it.
What is Teflon?
Teflon refers to the material of insulation, which has high insulation, high and low temperature resistance, and excellent aging resistance. It is a high-grade insulation material. The disadvantage is expensive This wire core is made of Teflon insulation.
