Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a flexible cable. Background Technology

[0002] Flexible cables are mainly used in industrial electronic systems, automated production lines, warehousing equipment, robots, metallurgical industry, machine tools and other automation fields. In power transmission, cables are frequently moved and transported during the laying process. During the transfer of cables, they are subjected to compression, dragging or bending, so the cables need to maintain good flexibility.

[0003] Currently, flexible cables on the market are usually made up of multiple tightly twisted cores. When a local part of the cable is subjected to an accidental impact, the tight twisted structure of the cores causes the stress on the core structure to be concentrated. This can easily cause the impact force to be directly transmitted to the surface of the twisted core structure, resulting in the breakage of some cores and thus affecting the safe use of the flexible cable. Utility Model Content

[0004] The purpose of this utility model is to provide a flexible cable. Through the structural design of the elastic skeleton and support, it can effectively ensure that the seven cable cores are evenly distributed and fixed inside the cable body, prevent multiple cable cores from being affected by impact forces at the same time, and solve the problem that the impact force generated by the impact is directly transmitted to the surface of the stranded cable core structure, causing some cable cores to break.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a flexible cable, comprising a cable body, which includes cable cores and an elastic skeleton. The cable cores consist of seven cables. The elastic skeleton has seven evenly spaced regular hexagonal honeycomb holes. Three support members are arranged inside the regular hexagonal honeycomb holes. Each support member includes an arc-shaped pad. The cable cores are fitted between the three arc-shaped pads. An elastic support plate is provided on the outer surface of the arc-shaped pads. An arc-shaped cavity is formed on the elastic support plate. The bottom of the elastic support plate is connected to the inner wall surface of the regular hexagonal honeycomb holes.

[0007] Furthermore, the cable core is made of multiple ultra-fine oxygen-free copper wires twisted together.

[0008] Furthermore, the elastic skeleton is made of thermoplastic polyester elastomer material, the support is made of silicone rubber material, and three arc-shaped pads form a circular space within the regular hexagonal honeycomb holes.

[0009] Furthermore, the outer surface of the elastic skeleton is coated with an insulating layer made of a specially modified TPE material, and the outer surface of the insulating layer is coated with a filling layer made of interwoven cotton yarn ropes.

[0010] Furthermore, the outer surface of the filling layer is laminated with a shielding layer, which is woven from high-density tin-plated copper wire, and the outer surface of the shielding layer is laminated with a tensile layer, which is made of aramid fibers spirally twisted together.

[0011] Furthermore, the outer surface of the tensile layer is laminated with an outer sheath, which is a wear-resistant polyurethane material with uniform thickness and a smooth surface.

[0012] This utility model has the following beneficial effects:

[0013] This invention utilizes a structural design of an elastic skeleton and supporting components. The cable cores are secured within hexagonal honeycomb holes on the elastic skeleton via three elastic support plates. This ensures that the seven cable cores are evenly distributed and fixed inside the cable body, effectively dispersing and weakening the impact force on the cable cores. This provides effective pressure resistance protection for the cable cores, ensuring that the seven cable cores are evenly distributed and fixed inside the cable body. It prevents multiple cable cores from being simultaneously subjected to impact forces, avoiding breakage of some cable cores due to accidental impacts to the cable body. This effectively improves the pressure resistance of the cable cores, ensuring the safe use of the cable body and extending its service life.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a flexible cable, including a cable body 1, the cable body 1 including cable cores 2 and an elastic skeleton 3, the number of cable cores 2 is seven, the cable cores 2 are made of multiple ultra-fine oxygen-free copper wires twisted together, and have high conductivity and ultra-flexibility, the elastic skeleton 3 has seven hexagonal honeycomb holes 301 evenly opened on it, the seven cable cores 2 are respectively located in the seven hexagonal honeycomb holes 301 on the elastic skeleton 3, the elastic skeleton 3 is made of thermoplastic polyester elastomer material, and has balanced softness, elastic recovery rate, flame retardancy, adhesion to optical fiber and low temperature performance, and can quickly recover after being compressed.

[0022] Three support members 4 are provided inside the regular hexagonal honeycomb hole 301. The support members 4 are made of silicone rubber material, which can absorb and weaken the impact force. The three arc-shaped pads 401 form a circular space inside the regular hexagonal honeycomb hole 301, which can facilitate the fitting and fixing of the cable core 2. The support member 4 includes the arc-shaped pads 401, and the cable core 2 is fitted between the three arc-shaped pads 401. An elastic support plate 402 is provided on the outer surface of the arc-shaped pads 401. An arc-shaped cavity 403 is opened on the elastic support plate 402. The bottom of the elastic support plate 402 is connected to the inner wall surface of the regular hexagonal honeycomb hole 301.

[0023] The outer surface of the elastic skeleton 3 is laminated with an insulation layer 5, which is made of a special modified TPE material. This allows the cable body 1 to have excellent electrical insulation and weather resistance. The outer surface of the insulation layer 5 is laminated with a filler layer 6, which is made of interwoven cotton yarn rope. This filler layer 6 can improve the structural stability of the cable body 1 and ensure the roundness of the cable body 1. The outer surface of the filler layer 6 is laminated with a shielding layer 7, which is made of high-density tin-plated copper wire braid. This can achieve efficient electromagnetic interference resistance. The outer surface of the shielding layer 7 is laminated with a tensile layer 8, which is made of spirally twisted aramid fiber. This tensile layer 8 can provide the main tensile strength for the cable body 1, protect the cable core 2 inside the cable body 1, and prevent the cable core 2 from breaking due to stress. The outer surface of the tensile layer 8 is laminated with an outer sheath 9, which is made of wear-resistant polyurethane material with uniform thickness and smooth surface. This outer sheath 9 has excellent flexibility, high wear resistance, oil resistance, hydrolysis resistance, tear resistance, and UV resistance. It is the key to ensuring the final performance of the cable body 1.

[0024] When a localized area of ​​the cable body 1 is subjected to an accidental impact, the impact force passes through the outer sheath 9, tensile layer 8, shielding layer 7, and filling layer 6 to reach the insulation layer 5. The impact force acts on the insulation layer 5, causing the insulation layer 5 to compress the elastic skeleton 3. When the elastic skeleton 3 is compressed, the impact force is effectively buffered and weakened by the material properties of the elastic skeleton 3 itself and the unique hexagonal cavity design of the regular hexagonal honeycomb holes 301. The weakened impact force acts on the corresponding support member 4 within the regular hexagonal honeycomb holes 301 through the elastic deformation of the elastic skeleton 3. Through the arc-shaped cavity 403 opened in the elastic support plate 402, the elastic support plate 402 undergoes elastic compression and pushes the inner arc surface of the arc-shaped pad 401 to compress against the surface of the cable core 2. Through the arc-shaped design of the arc-shaped pad 401, the impact force, which has been weakened again by the elastic compression of the elastic support plate 402, is evenly distributed on the surface of the cable core 2, thereby fully dispersing and weakening the impact force on the cable core 2, achieving effective pressure resistance protection for the cable core 2.
