Embodiment 1
[0021] as attached figure 1 As shown, a kind of anti-electromagnetic interference shielded cable is a coaxial cable, including a conductive layer 10, an insulating layer 11 wrapped outside the conductive layer 10, a shielding layer 12 wrapped outside the insulating layer 11, and wrapped The braided layer 13 covered outside the shielding layer 12 and the outer protective sheath 14 covered outside the braided layer 13 . Wherein, the conductive layer 10, the insulating layer 11, the shielding layer 12, the braiding layer 13, and the outer protective sheath 14 are arranged coaxially.
[0022] The conductive layer 10 may consist of one conductive core or multiple conductive cores with insulating coatings, or may be formed by winding multiple conductive threads. The conductive core or conductive wire can be made of conductive metal materials, such as copper, aluminum, etc., or conductive alloy materials, such as copper-zinc alloy, copper-silver alloy, copper-tin alloy, etc.

Embodiment 2
[0033] as attached figure 2 As shown, an anti-electromagnetic interference shielded cable includes a plurality of conductive layers 20, each conductive layer is covered with an insulating layer 21 and a shielding layer 22, and a braided layer is covered with a plurality of conductive layers 23 and the outer protective cover 24 that is coated on the outside of braided layer 23. The shielding layer 22 shields each conductive layer 20 individually, which can not only prevent external factors from interfering with the internal transmission signals of the conductive layer 20 but also prevent interference that occurs when different signals are transmitted between the conductive layers. The composition and preparation method of each conductive layer 20 , insulating layer 21 , shielding layer 22 , braiding layer 23 , and outer protective sheath 24 are the same as those in Embodiment 1.
