All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The inventor of the application finds that if the conducting wire is not provided with the shielding layer, the conducting wire becomes soft and has good flexibility, but the conducting wire cannot shield external interference and generate electromagnetic radiation outwards without the shielding layer, so that the electrical performance and the data transmission performance of the conducting wire are poor, data cannot be transmitted, and the conducting wire cannot be used for charging a terminal. If the shielding layer is designed, the wire is relatively stiff, the bending performance of the wire is easily deteriorated, and the wire can be even broken or damaged in the using process, so that the function of the wire is lost. For this reason, the inventors of the present application have made extensive studies and experiments to provide the following examples.

The shielding layer 13 of the present embodiment may include one or more metal wires 131, and the metal wires 131 have a conductor function, for example. In one embodiment, the shielding layer 13 includes a metal wire 131, and the metal wire 131 may be one of a tin-plated copper wire, a bare copper wire, and an alloy copper wire, but may be other metal materials. The wire 131 may be wound around the outer circumference of the inner cladding 12 along the extending direction of the wire core 11, so as to surround the inner cladding 12.

For example, the metal wire 131 may be wound on the outer surface of the inner cladding 12 to form a sub-layer. Alternatively, the flexible wire 132 may be wound around a sub-layer formed by winding the metal wire 131 around the outer periphery of the inner cladding 12, and the metal wire 131 may be wound around the outer periphery of the flexible wire 132.

In some embodiments, the wire 10 may include a plurality of shielding layers 13, and after one shielding layer 13 covers the outer periphery of the inner cladding 12, another shielding layer 13 is overlapped on the previous shielding layer 13, and thus the shielding layers are arranged layer by layer.
