It should be noted that, based on the same coating manner as in fig. 2, fig. 4, or fig. 6, in order to improve the interference resistance of the cable, a second metal layer D may be further disposed between the conductive layer B and the protective film C of the electromagnetic shielding film for assisting the conductive layer B to perform shielding, because the second metal layer D is disposed between the conductive layer B and the protective film C, the guiding speed of the electromagnetic wave may be accelerated, the electromagnetic wave may be quickly taken out of the cable, and the interference of the electromagnetic wave on the core conductor may be better avoided. Therefore, when the cable with the connector needs higher signal transmission speed or higher transmission power, the second metal layer D can be arranged between the conductive layer B and the protective film C, the dredging effect of the second metal layer on electromagnetic waves is increased, the anti-interference capacity of the wire core conductor is improved, and the structural schematic diagram of the electromagnetic shielding film is shown in figure 8, wherein A is the first metal layer, B is the conductive layer, D is the second metal layer, and C is the protective film.
Optionally, the thickness of the second metal layer D is 5 to 50 micrometers, and since the thickness of the second metal layer directly affects the dredging effect on the electromagnetic waves, the second metal layers with different thicknesses can be adopted according to the requirement of the cable conductor on the interference resistance.

In addition, the conductivity of the metal particles in the conductive layer directly affects the derivation and attenuation of the electromagnetic wave, so the conductive particles in the conductive layer generally select metal particles with stronger conductivity, such as metal particles of gold, silver, copper, nickel, aluminum, etc., and the mass proportion of the metal particles also directly affects the conductivity of the conductive layer, the larger the mass proportion of the metal particles is, i.e. the denser the metal particles are, the stronger the conductivity of the electromagnetic wave is, and the smaller the mass proportion of the metal particles is, i.e. the more sparse the metal particles are, the weaker the less the conductivity of the electromagnetic wave is, so the mass proportion of the metal particles in the conductive layer can be adjusted according to the anti-interference capability required by the core conductor, preferably, the mass proportion of the metal particles in the conductive layer is 1% -80%, and under the condition that the thickness and the composition of each layer of the electromagnetic shielding film are the same, the anti-interference capability of the core conductor can reach, and at maximum, 103dB can be achieved.
