With the rapid development of electronic technology, the speed and quality requirements of signal transmission of the equipment are becoming higher and higher, however, the problem of signal interference is becoming increasingly prominent. In the field of weak current, when using cables for signal or data transmission, external electromagnetic waves are easy to cause electromagnetic interference to the cables. Even if a magnetic ring is arranged outside the cable to suppress high-frequency interference signals, for a connector with multiple signal lines, the crossing of the signal lines will still cause mutual interference.
