[0002] The cable line is applied in the scene of single cable line or multiple cable lines, and the cable line is wrapped by the cable shielding tape along the total length or part of the length of the cable line, which plays a protection and shielding role.

[0003] The traditional cable shielding tape adopts a kind of woven metal wire structure mesh belt, has the advantages of small volume and light weight, can effectively shield electromagnetic radiation, and protects cable and core wire.

[0004] However, due to the use of metal mesh as shielding material only, the shielding effect is limited, the cable is not tightly wrapped, and the protection and shielding effect of the cable are not good. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a composite shielding tape to solve the above problems and improve the shielding effect and cable wrapping tightness.

[0006] To achieve the above object, the utility model provides the following technical scheme:

[0007] A composite shielding tape comprises a metal mesh belt of outer layer, characterized in that the metal mesh belt is tightly wrapped with a flexible shielding layer inside during weaving to form a composite structure, and one side of the metal mesh belt is provided with a double-sided adhesive layer for firmly adhering and fixing the cable when wrapping the cable.

[0008] Further, the metal mesh belt is woven into a double-layer structure to form a metal mesh sleeve, and the flexible shielding layer is tightly and uniformly wrapped in the inner space of the double-layer metal mesh sleeve.

[0009] Further, the metal mesh belt of the double-layer metal mesh sleeve is woven with tin-plated copper steel wire to enhance its conductivity and mechanical strength, thereby effectively resisting low-frequency interference.

[0010] Further, the flexible shielding layer is composed of a non-magnetic metal foil, which has excellent conductivity and can effectively absorb high-frequency electromagnetic waves, thereby resisting high-frequency interference.

[0011] Further, the non-magnetic metal foil is specifically aluminum foil or copper foil, and these two materials are preferred for manufacturing the flexible shielding layer due to their good conductivity and economy.

[0012] The beneficial effect is that the composite shielding tape can be closely attached when wrapping cables, has simple structure and remarkably enhanced shielding effect, and provides better protection for the cable and core wire. BRIEF DESCRIPTION OF DRAWINGS
