Description

Technical Field

[0001] The utility model relates to the field of sway-resistant cables, in particular to a sway-resistant cable. Background Art

[0002] The history of cables can be traced back to the early 19th century, when people began to use bare copper wires to transmit electrical shielding. With the development of technology, people began to use insulating materials to wrap copper wire cables. Today, cables are widely used in various fields such as electricity, communications, control, and computers. In power lines, their proportion is gradually increasing. The widespread use of cables has brought great convenience to people's lives.

[0003] When traditional cables are in use, the internal circuits are usually fixed to the inner wall of the insulation layer. During the swinging and bending process, the internal circuits will be affected by the outer layer and will be stretched. When the cables are excessively swung and bent, the diameter of the internal circuits of the cable will change, reducing the swinging and bending performance and service life of the circuits. Therefore, a swing-resistant cable is proposed to address the above problem. Utility Model Content

[0004] In order to make up for the shortcomings of the prior art, the line diameter inside the cable changes, which reduces the swing and bending performance and service life of the line. The utility model proposes a swing-resistant cable.

[0006] Preferably, the tensile layer is made of steel wire, and the insulating layer is made of polyvinyl chloride.

[0007] Preferably, the bending-resistant layer is made of rubber, and a grounding wire is fixedly installed on the inner wall of the bending-resistant layer.

[0009] Preferably, the filling layer is made of polyester fiber, and the shielding layer is made of copper foil.

[0010] Preferably, the cold-resistant layer is made of vinyl acrylate copolymer, and the protective layer is made of polyethylene.

[0011] Preferably, a sleeve is fixedly mounted on the surface of the cold-resistant layer, a through hole is opened on the surface of the sleeve, and an inner cavity of the through hole is slidably connected to the insulating layer.

[0012] The utility model is beneficial in that:

[0013] The utility model uses a tensile layer made of steel wire to enhance the tensile resistance of the conductor and protect the conductor from being broken during swinging and bending. The bending-resistant layer made of rubber can bend the bending-resistant layer during the swinging and bending of the cable, and the bending-resistant layer can squeeze the groove during the swinging and bending, thereby reducing the direct effect of external force on the conductor. The filling layer made of polyester fiber can prevent the internal structure of the cable from being deformed, increase the tensile strength of the cable, and prevent the cable from being damaged during transportation and use. The shielding layer made of copper foil can prevent external electromagnetic waves from entering the cable, and can also prevent the electromagnetic waves inside the cable from radiating outward, thereby ensuring the stable transmission of the cable signal. The cold-resistant layer made of vinyl acrylate copolymer can protect the interior of the cable when it is in a low-temperature environment. The protective layer made of polyethylene can achieve the purposes of wear resistance and aging resistance. BRIEF DESCRIPTION OF THE DRAWINGS
