The difference between USB3.1 cable and power cable comparison and the introduction of magnetic ring
USB3.1 cable is used to transmit data signals, its outermost layer is a layer of plastic skin used to protect the wire; USB3.1 cable is the second layer of several fine copper wire woven network, the third layer is a layer of aluminum foil, the role of the second and third layer is to play a shielding role to prevent data signal radiation and interference, one end of it must be connected to the signal ground of the circuit, otherwise there is no shielding effect; the innermost layer is used to The innermost layer is used to transmit data signals of one to several wrapped with plastic skin of thin wire, the wire diameter is small.
Power line is used for power transmission wire, no shielding layer, its outer layer is a layer of plastic skin or rubber used to protect the wire, the inner layer is used to transmit power to the core wire, generally two to four, each core wire is also wrapped outside a layer of plastic skin or rubber for insulation between the core wire, the core wire diameter is larger.
The difference between them is that the wire goes current, while the USB3.1 line goes electrical and digital signals or waveforms, the way the data is transmitted on the transmission channel.
The most important role of the data line magnetic ring is to eliminate and reduce electromagnetic interference. Because the electromagnetic interference of computer equipment is large, especially in the computer room and other environments with more computers. Therefore, most of the high-grade peripheral connection cable with a magnetic ring, as a way to reduce the impact of electromagnetic interference on the peripheral data transmission. In addition, the use of attention to the data cable with a magnetic ring end connected to the PC, so that the effect is the best.
Data line magnetic ring in the selection, most of the nickel-zinc magnetic ring, RH flux-based, the outer diameter of the magnetic ring conditions allow as much as possible to choose a larger, longer length, the inner diameter as much as possible to fit the outer diameter of the data line, so that the performance of anti-interference to achieve the best results. When the volume is certain, long and thin than short and thick inhibit the effect of good internal strength, the smaller the inhibition effect is also better.
