A cable is an electrical connection element consisting of one or more metal wires and an insulating layer.
It works based on the following points:
1.Conductivity: The metal wire in the cable has good conductivity and can transmit current.
2.Insulation layer: The metal conductor of the cable is wrapped in a layer of insulating material, such as plastic or rubber, to prevent current leakage and short circuit, and to provide protection.
3. Shielding layer (optional): Some cables will also add a shielding layer outside the insulation layer to prevent interference signals from entering or signal leakage.
4. Outer sheath: The outer surface of the cable is usually also covered with an outer sheath, which is used to protect the cable from physical damage and environmental conditions.
5. Transmission signal: When the two ends of the cable are connected to the power supply or electronic device, the current will enter the device from the power supply through the cable to complete the function of power transmission or signal transmission.
In short, the working principle of the cable is to transmit the current through the internal metal wire, and prevent the leakage and short circuit of the current through insulation, so as to ensure the transmission of electrical energy or signal.
The shield and outer sheath provide better signal protection and overall cable durability.
