Description

Technical Field

[0001] The utility model belongs to the field of cable equipment, and particularly relates to an outdoor flexible cable with high pressure resistance and high deformation resistance. Background Art

[0002] Outdoor flexible cable is a cable specially designed for outdoor environment. Compared with ordinary cables, it has stronger flexibility and adaptability, and can work stably under complex outdoor conditions. In outdoor environment, cables may be squeezed, stepped on or other pressures. Cables with high compression and deformation resistance can better withstand these pressures, reduce the occurrence of failures, and improve the reliability of the system. Although the current outdoor flexible cable has a certain compression and deformation resistance, in some cases, it may not meet the requirements of high compression and deformation resistance. This may become its disadvantage in some specific applications. In actual use, outdoor flexible cables may have the risk of excessive deformation or structural damage under extreme mechanical pressure or heavy load environment. This may limit its use in some high-demand fields, such as heavy industry, mining and other industries. This is because of the lack of high compression and deformation resistance components. The lack of high compression and deformation resistance components will not only lead to the above problems, but also the cable may be structurally damaged or performance degraded if it encounters strong extrusion, heavy load or unexpected impact. This may affect the reliability and service life of the cable, so it is necessary to propose a new structure to solve the above technical problems. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5 The utility model provides a technical solution: a high-compression and high-deformation outdoor flexible cable, comprising: an outer ring component, a compression-resistant deformation layer 200 and a core component, the outer ring component comprises: a protective layer 100, a rubber layer 110 and a hollow layer, the inner surface of the protective layer 100 is installed with a rubber layer 110, a hollow layer is arranged between the rubber layer 110 and the compression-resistant deformation layer 200, a spring 120 is installed inside the hollow layer, and a memory metal is installed inside the compression-resistant deformation layer 200 Strip 220, anti-tensile rope 210, the inner surface of the compressive deformation layer 200 is installed with a wrapping tape 230, and a plurality of core components are installed inside the compressive deformation layer 200. The plurality of core components have the same structure. The core components include: conductor 300, shielding layer 1 310, insulating layer 330 and shielding layer 2 320. Shielding layer 1 310 is installed on the outer surface of the conductor 300, and shielding layer 2 320 for shielding the insulating layer 330 is installed on the outer surface of the shielding layer 1 310.

[0022] See also Figures 1 to 5 As the first embodiment of the utility model: the outer surface of the protective layer 100 is a bellows structure, the material of the protective layer 100 is polyurethane, the material of the rubber layer 110 is natural rubber, the thickness and diameter of the rubber layer 110 are smaller than the thickness and diameter of the protective layer 100, and the hollow layer between the rubber layer 110 and the compression deformation resistance layer 200 is annularly installed with multiple springs 120;

[0023] During use, when the cable is subjected to external pressure, the external protective layer 100 and the rubber layer 110 inside the protective layer 100 can start the initial pressure resistance. At this time, when the protective layer 100 and the rubber layer 110 are pressed, the spring 120 of the hollow layer on the inner surface of the rubber layer 110 will deform and absorb part of the pressure. Because the spring 120 is connected to the rubber layer 110 and the anti-compression deformation layer 200, when the spring 120 recovers its deformation, its rebound force will not act on the object under external pressure, but will only be absorbed by the rubber layer 110 and the anti-compression deformation layer. 200 is absorbed, thereby starting the compression resistance. At the same time, the protective layer 100 is a bellows structure. When the protective layer 100 is subjected to the force of deformation, the protective layer 100 of the bellows structure is matched with the compression deformation layer 200 to increase the elasticity and deformation capacity of the cable, making it less likely to be damaged. The spring 120 can provide additional support when the cable is subjected to external pressure, reduce the impact on the internal structure of the cable, and improve the compression resistance. At the same time, the spring 120 in the hollow layer can play a role of seismic isolation and buffering, reduce the vibration and impact of the cable during use, and extend the life of the cable.

[0024] See also Figures 1 to 5 As a second embodiment of the utility model: the upper end of the spring 120 is connected to the inner wall of the rubber layer 110, the lower end of the spring 120 is connected to the outer surface of the compression-resistant deformation layer 200, and a plurality of memory metal strips 220 are installed in a ring shape inside the compression-resistant deformation layer 200, and an anti-stretching rope 210 is installed between every two memory metal strips 220;

[0025] The anti-stretching rope 210 is in a spiral twist structure, and the material of the anti-stretching rope 210 is aluminum alloy. The thickness of the wrapping tape 230 on the inner surface of the anti-compression deformation layer 200 is less than the thickness of the anti-compression deformation layer 200, and the inner surface of the wrapping tape 230 is provided with a filling layer 340;

[0026] When in use, since an anti-stretching rope 210 with a spiral twisted structure is installed between the memory metal strips 220, the installation of the memory metal strips 220 and the anti-stretching rope 210 can enhance the compressive resistance of the cable, so that it can maintain a good shape and structural stability when subjected to external pressure. At the same time, the presence of the twisted anti-stretching rope 210 can improve the tensile resistance of the cable and reduce the impact on the internal structure of the cable during the stretching process. The memory metal strips 220 have a memory function and can restore their original shape after being subjected to external pressure or deformation, which helps to maintain the stability and reliability of the cable without delaying its deformation.

[0027] The filling layer 340 has a plurality of core components arranged in a ring-shaped structure inside. The conductor 300 of the core component has the same structure as the anti-tensile rope 210 but has different specifications and materials. The shielding layer 1 310 on the outer surface of the conductor 300 has the same structure as the shielding layer 2 320 on the outer surface of the insulating layer 330. Because the conductor 300 inside the core component is also in a spiral twist shape, it can further improve the compression and tensile resistance of the cable, making it less likely to break when subjected to external mechanical stress. At the same time, this structure allows the cable to deform more freely when bent or twisted without causing excessive stress concentration on the conductor 300, thereby improving the flexibility and reliability of the cable.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
