Embodiment Construction

[0020] Such as figure 1 As shown, the electromagnetic wave shielding cable made of copper-iron alloy includes a conductor 1 , an insulator 2 , a constraint layer 3 , a shielding material 4 , and a protective layer 5 . Constraint layer 3 is composed of aluminum foil and polyester tape and sheet tape.

[0021] A plurality of conductors 1 are bundled together after being surrounded by respective insulators 2 . The enclosed plurality of conductors 1 are enclosed by a constraining layer 3 and surrounded by a braided copper-iron alloy wire mesh or a sheet-type shielding material layer 4 . The layer 4 of shielding material is then surrounded by a protective layer 5 .

[0022] The characteristic of the cable is that on the conductor wrapped by the insulator, there are tiny crystal grains in the copper matrix, which are mainly composed of iron, and the content of iron is 5-45% of the total weight of the alloy. , constitute a copper-iron alloy mesh shielding material with a wire diam...

Abstract

The invention provides a cable capable of shielding an electromagnetic wave. The cable capable of shielding the electromagnetic wave is characterized by comprising cable cores, insulator layers, a shielding material layer and a protecting layer. The cable cores are made of conductors, the insulator layers covers the cable cores in a surrounding mode, the shielding material layer covers the outside of the insulator layers in a surrounding mode, and the protecting layer covers the outside of the shielding material layer. The shielding material layer is made of a copper iron alloy. The copper iron alloy comprises, by mass, a copper substrate and crystal particles which are dispersed in the copper substrate, and iron serves the main ingredient of the crystal particles. The content of the iron accounts for 5% to 45% of the total weight of the copper iron alloy. The effect of shielding of the electromagnetic wave can be improved, the appearance is more attractive, the weight is lighter, the condition that the conflict is generated due to the fact that a ferrite magnetic core is not utilized appropriately cannot occur, the mechanical strength of the copper iron alloy is extremely good, the diameter of a shielding wire body can be reduced, the weight of the cable is lightened, and the contribution is provided for the operating production.

Description

technical field [0001] The invention relates to a cable, in particular to a cable for shielding electromagnetic waves. Background technique [0002] In the past, the electromagnetic wave shielding of the cable was to wrap the conductive metal such as copper or aluminum with shielding effect on the cable. However, this method only shields the electric waves in the electromagnetic waves, and has no obvious effect on the magnetic waves. Also, shielding materials made of conductive metals can generate common-mode noise due to antenna effects. Especially for weak currents, as a method of reducing the antenna effect of the shielding material made of conductive metal, it is implemented by wrapping the wire with a ferrite core. Contents of the invention [0003] The object of the present invention is to provide an electromagnetic wave shielding cable made of copper-iron alloy to solve the above problems. [0004] The invention provides a cable for shielding electromagnetic wave...
