Why do you want to set anti-interference magnetic rings? The motherboard, CPU, power supply and IDE data line in the computer case are all working in a high frequency state, so there are a lot of space stray electromagnetic interference signals in the case, and the signal strength is several times to dozens of times that outside the case! USB wires without magnetic rings are not shielded in this space, so these USB wires become good antennas to receive all kinds of messy high-frequency signals in the surrounding environment, and these signals are superimposed on the originally transmitted signals, even changing the originally transmitted useful signals, which is prone to problems.
In order to improve the transmission rate and stability and reduce the interference of transmission lines to sound cards and other equipment, an electrostatic shielding layer is designed. The shielding layer is made of thin metal foil or thin copper wire network, and the surface effect principle of electrostatic field is applied. That is to say, the outer surface of the data transmission line is covered with a metal film, and this shielding layer is grounded with the chassis, which can well isolate the data line from the space interference signal!
Absorbing magnetic ring, also known as ferrite magnetic ring, is often used for detachable separation magnetic ring. It is a common anti-interference component in electronic circuits and has a good suppression effect on high-frequency noise. Generally made of ferrite material (Mn-Zn). Magnetic rings have different impedance characteristics at different frequencies. Generally, the impedance is very small at low frequency, and the impedance of magnetic ring increases sharply when the signal frequency increases. Normal useful signals can pass well, high-frequency interference signals can be suppressed well, and the cost is low.
It's bound to succeed. In general USB devices, a group of wires completely bypass the magnetic ring, so the high-frequency current will be greatly attenuated when this group of wires is grounded. But if you have a single-core signal around the magnetic ring, the data will definitely not move and the speed will not go up.
