Description

Technical Field

[0001] This utility model relates to the field of anti-interference cable technology, specifically to an insulated anti-interference cable. Background Technology

[0002] A cable is a conductor used to transmit electrical energy, information, or signals. It typically consists of one or more insulated conductors with an external protective layer. Cables are widely used in power systems, communications, computer networks, industrial control, traffic signals, and more.

[0003] In order to avoid electromagnetic interference, existing cables usually have a metal braided mesh installed on the outside of the conductor for electromagnetic protection. In order to ensure the protective effect of the metal braided mesh, it is usually tightly woven. However, the tight weave reduces the flexibility of the metal braided mesh during use, making it easy to break or be damaged when bending, thus narrowing the applicable range of the cable. Therefore, an insulated anti-interference cable is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an insulated anti-interference cable to solve the problem that tightly woven metal mesh reduces the flexibility of the metal mesh during use, making it prone to breakage or damage when bent, thereby reducing the applicable range of the cable.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] An insulated anti-interference cable, comprising:

[0007] A fixing rope, wherein a retainer is provided on the outside of the fixing rope, and at least one wire is provided inside the retainer;

[0008] A protective component, disposed on the outside of the retainer, is used to provide protection for the conductor. The protective component includes a shield and a protective component. The shield is disposed on the outside of the retainer and is used to shield electromagnetic signals. The protective component is disposed on the outside of the shield and is used to maintain the shape of the shield. The shield and the protective component work together to protect the conductor.

[0009] Furthermore, the shielding component includes a fixing layer disposed on the outside of the retainer, and the fixing layer contains multiple connecting tubes, which are annular in shape, with a shielding tube between adjacent connecting tubes.

[0010] Furthermore, the protective component includes a retaining layer disposed outside the fixing layer, and the retaining layer is spiral-shaped, with an insulating layer disposed outside the retaining layer.

[0011] Furthermore, an armor layer and a protective layer are sequentially provided on the outer side of the insulating layer.

[0012] Furthermore, both the shielding tube and the connecting tube are made of metal.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model, through the setting of shielding and protective components, achieves the replacement of braided metal mesh by cooperating with a fixing layer, shielding tube, connecting tube, protective layer, retaining layer, insulation layer and armor layer, thereby improving the overall flexibility of the conductor during bending and avoiding the reduction of flexibility of the metal braided mesh during use, which would easily lead to breakage or damage when bending, thus increasing the range of applications of the cable.

[0025] like Figures 1 to 4 As shown, an insulated anti-interference cable includes: a fixing rope 1, a retainer 101 on the outside of the fixing rope 1, and at least one conductor 2 inside the retainer 101; a protective component, disposed on the outside of the retainer 101, for providing protection for the conductor 2, the protective component including a shield 3 and a protective component 4, the shield 3 being disposed on the outside of the retainer 101 for shielding electromagnetic signals, and the protective component 4 being disposed on the outside of the shield 3 for maintaining the shape of the shield 3, and the shield 3 and the protective component 4 working together to protect the conductor 2. Specifically, during use, the conductor 2 is insulated and electromagnetically protected by the cooperation of the shield 3 and the protective component 4, ensuring the stability of the conductor 2 during use. The conductor 2 can provide tension to the fixing rope 1 during use, preventing the fixing rope 1 from breaking due to stress. The conductor 2 can be a braided tensile rope or a braided steel strand. During use, the retainer 101 can maintain the position of the conductor 2, preventing the conductor 2 from squeezing each other when under stress. The retainer 101 can be made of plastic or rubber.

[0026] like Figures 1 to 4As shown, the shielding component 3 includes a fixing layer 301, which is disposed on the outside of the retainer 101. The fixing layer 301 has multiple connecting tubes 303 inside, and the connecting tubes 303 are in the shape of a ring. A shielding tube 302 is provided between adjacent connecting tubes 303. Specifically, during use, the connecting tubes 303 and the shielding tubes 302 cooperate to shield the wire 2, ensuring the stability of the wire 2 during information transmission. The fixing layer 301 can be made of rubber or silicone, thereby maintaining the position of the shielding tubes 302 and the connecting tubes 303 during use. The multiple shielding tubes 302 are connected by the connecting tubes 303, thereby providing support for the fixing layer 301 during use and ensuring the strength of the fixing layer 301 when bent.

[0027] like Figures 1 to 4 As shown, the protective component 4 includes a retaining layer 402, which is disposed outside the fixing layer 301 and is spiral in shape. An insulating layer 403 is provided outside the retaining layer 402. Specifically, the insulating layer 403 can be made of polyvinyl chloride or insulating rubber. During use, the retaining layer 402 can maintain the shape of the fixing layer 301, thereby increasing the compressive strength of the retaining layer 402 during use.

[0028] like Figures 1 to 4 As shown, an armor layer 404 and a protective layer 401 are sequentially provided on the outside of the insulating layer 403. Specifically, the protective layer 401 can be made of polyvinyl chloride, polyethylene, or low-smoke halogen-free material, thereby protecting the insulating layer 403 during use. The armor layer 404 can be made of aluminum foil or copper foil. During use, the armor layer 404, together with the shielding tube 302 and the connecting tube 303, further improves the signal shielding effect while protecting the insulating layer 403.

[0029] like Figures 1 to 4 As shown, both the shielding tube 302 and the connecting tube 303 are made of metal. Specifically, the metal shielding tube 302 and the connecting tube 303 can shield electromagnetic interference during use, ensuring the stability of the conductor 2 during use. The connecting tube 303 can increase the spacing between adjacent shielding tubes 302 during use, preventing excessive stretching on one side of the shielding tube 302 during bending. The shielding tube 302 is a corrugated metal flexible tube, and its shape can be bent according to usage requirements. The shielding tube 302 can improve the flexibility of the fixing layer 301 during use. The shielding tube 302 can be made of stainless steel or copper alloy.
