The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses an electric wire with an electromagnetic shielding function.

Referring to fig. 1 and 2, fig. 3, an electric wire with electromagnetic shielding function, including surrounding layer 1, the inside fixedly connected with inner cladding 2 of surrounding layer 1, the inside fixedly connected with buffer layer 3 of inner cladding 2, the inside of buffer layer 3 evenly is provided with a plurality of mounting holes 4, the internally mounted of mounting hole 4 has sinle silk 5, a plurality of archs 6 of the inner wall fixedly connected with of surrounding layer 1, the recess 7 with protruding 6 adaptations is seted up to the periphery of inner cladding 2, and the peripheral coating of inner cladding 2 has electrically conductive complexing agent 8. Firstly, when an electromagnetic field passes through the space between the outer cladding layer 1 and the inner cladding layer 2, the concave-convex surfaces formed by the protrusions 6 and the grooves 7 form a blocking section for the magnetic field, the formation of magnetic field propagation is increased, and meanwhile, the magnetic field is consumed and isolated by the conductive complexing agent 8 when being propagated along the surfaces of the protrusions 6 and the grooves 7, so that the penetration rate of the magnetic field is effectively reduced, and the transmission efficiency of a circuit is improved.
