[0002] Copper is a good conductive material that can effectively transmit electric current and electromagnetic signals. In the field of electronic communications, copper wires are often used to transmit various electromagnetic signals, such as audio, video, and data signals. When the machine equipment is in operation, multi-core copper wires need to undergo repeated bending actions. The tensile strength of the core conductor is insufficient, and it is easy to break the wire and core. In addition, copper wires may be interfered when transmitting electromagnetic signals, especially when transmitting signals over longer distances or at high frequencies. Therefore, electromagnetic shielding needs to be provided for the copper wires. Utility Model Content
