The USB cable without the magnetic ring does not take shielding measures in this space, so these USB cables become very good antennas. The magnetic ring receives various high-frequency signals in the surrounding environment, and these signals are superimposed on the originally transmitted signals. On the other hand, it will even change the useful signal that was originally transmitted, and it is prone to problems. In order to improve the transmission rate and stability, and also to reduce the interference of transmission lines on other devices, such as sound cards, an electrostatic shielding layer is designed. The shielding layer is made of a thin metal foil or a plurality of fine copper wires woven into a mesh shape, and the principle of the surface effect of the electrostatic field is applied. That is, the outer surface of the data transmission line is covered with a metal film, and the shielding layer and the chassis are grounded, so that the data line can be isolated from the space interference signal. Absorption magnetic ring, also known as ferrite ring, is often used in the detachable magnetic ring. It is a commonly used anti-interference element in electronic circuits, and has a good inhibitory effect on high-frequency noise. Generally, ferrite materials are used. Made of (Mn-Zn). The magnetic ring has different impedance characteristics at different frequencies. Generally, the impedance at the low frequency is very small. When the signal frequency rises, the impedance exhibited by the magnetic ring rises sharply. The normal and useful signals are passed very well, and the passage of high-frequency interference signals can be well suppressed, and the cost is low.
