Description

Technical Field

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

[0002] When commonly used cables are employed in the cable carriers and motion drive systems of industrial robot arms, the high mobility and large range of stretching and twisting movements of the robot arms can lead to problems such as cable twisting, sheath wear, and core breakage, resulting in open circuits, short circuits, and sheath ruptures. These unexpected situations can cause serious harm to machinery and personnel, and also highlight the shortcomings of industrial robots, such as their short lifespan and high cost.

[0003] Currently, cables have poor flexibility. In order to ensure good wear resistance, high support strength, and waterproof and shielding performance, cables are usually made into multiple layers. Therefore, when the cable is moved, twisted, or pulled with large amplitude, it is easy to cause the cable to break and become unusable. To address this, we propose a high-speed ultra-flexible cable. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed, ultra-flexible cable to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-speed ultra-flexible cable, comprising a cable body, the cable body comprising multiple cores and a wrapping layer that wraps the multiple cores together, the cores being made of multiple ultra-fine copper fibers, the cores being provided with an insulation layer with a three-dimensional braided structure, the insulation layer being provided with a shielding layer, the shielding layer being provided with a protective sheath layer, the wrapping layer being provided with a waterproof layer, and the waterproof layer being provided with a highly wear-resistant sheath.

[0006] Preferably, the high wear-resistant sheath has an outer coating, and the outer coating contains microcapsules containing repair fluid.

[0007] Preferably, the insulating layer is made of a superelastic polyurethane or silicone composite material.

[0008] Preferably, the high wear-resistant sheath is made of carbon fiber reinforced polymer or ceramic-coated polyester.

[0009] Preferably, the surface of the ultrafine copper fiber is silver-plated.

[0010] Preferably, a filling layer is provided inside the wrapping layer located outside the core.

[0011] Preferably, the filler layer is made of elastic rubber.

[0012] Preferably, the waterproof layer is a water-blocking tape, and the water-blocking tape overlaps and wraps around the outer surface of the wrapping layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses multiple ultra-fine copper fibers to make the core of the cable. The ultra-fine copper fibers are used as the conductor material, which makes the cable more flexible and has lower resistance. The insulation layer is made of ultra-elastic polyurethane or silicone composite material. The ultra-elastic polyurethane or silicone composite material has good temperature resistance and fatigue resistance. The three-dimensional braided structure of the insulation layer can increase the toughness of the material, so that it can automatically recover its shape when bent or stretched, reducing damage caused by repeated movement.

[0015] 2. This utility model uses a high wear-resistant sheath made of carbon fiber reinforced polymer or ceramic coated polyester material, which not only gives the cable body excellent wear resistance, but also effectively protects the internal structure from external physical damage. The outer coating with embedded micro-adhesive containing repair fluid enables the cable body to have good self-repair function, which can cope with surface scratches or minor damage and enhance the service life of the cable body.

[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 1-3This utility model provides a technical solution: a high-speed ultra-flexible cable, including a cable body 1, the cable body 1 including multiple cores 2 and a wrapping layer 7 that wraps the multiple cores 2 together, the cores 2 being made of multiple ultra-fine copper fibers 21.

[0022] It should be noted that the core 2 is made of multiple ultra-fine copper fibers 21. The ultra-fine copper fibers 21 are used as conductor materials, which makes the cable more flexible and has lower resistance, higher bending performance, and can adapt to more complex motion trajectories, avoiding the breakage of traditional cables due to frequent bending.

[0023] The core 2 is provided with an insulation layer 3 with a three-dimensional braided structure on the outside, a shielding layer 4 is provided on the outside of the insulation layer 3, and a protective sleeve layer 5 is provided on the outside of the shielding layer 4. The wrapping tape layer 7 is provided with a waterproof layer 8 on the outside, and a highly wear-resistant protective sleeve 9 is provided on the outside of the waterproof layer 8.

[0024] It should be noted that the insulation layer 3 is made of super-elastic polyurethane or silicone composite material. Super-elastic polyurethane or silicone composite material has good temperature resistance and fatigue resistance. The three-dimensional braided structure of the insulation layer 3 can increase the toughness of the material, so that it can automatically recover its shape when bent or stretched, reducing damage caused by repeated movement. The wrapping layer 7 can stably position the core 2 and ensure the stability of the core 2. The waterproof layer 8 has a good waterproof effect. The high wear-resistant sheath 9 makes the cable body 1 have good wear resistance.

[0025] The high wear-resistant sheath 9 has an outer coating 10 on its exterior, and the outer coating 10 contains microcapsules containing repair fluid.

[0026] It should be noted that by setting an outer coating 10 embedded with micro-adhesive containing repair fluid, the cable body 1 can have a good self-repair function, which can cope with surface scratches or minor damage and enhance the service life of the cable body 1.

[0027] The insulation layer 3 is made of ultra-elastic polyurethane or silicone composite material.

[0028] It should be noted that using super-elastic polyurethane or silicone composite material as insulation layer 3, which has excellent temperature resistance and fatigue resistance, is beneficial for protecting the core 2.

[0029] The high abrasion resistant sheath 9 is made of carbon fiber reinforced polymer or ceramic-coated polyester.

[0030] It should be noted that the high wear-resistant sheath 9, made of carbon fiber reinforced polymer or ceramic-coated polyester material, not only gives the cable body 1 excellent wear resistance, but also effectively protects the internal structure from external physical damage.

[0031] The surface of the ultrafine copper fiber 21 is silver-plated.

[0032] It should be noted that by applying silver plating to the surface of the ultrafine copper fiber 21, the durability of the cable can be increased and oxidation can be reduced.

[0033] The inner layer 7 is provided with a filling layer 6 located outside the core 2.

[0034] It should be noted that the filler layer 6 can maintain the stability of the internal structure of the cable, prevent the conductor and the insulation layer 3 from sliding or shifting, maintain the shape and structure of the cable, and increase the tensile and compressive strength of the cable, making it less prone to breakage or damage under tension or external pressure.

[0035] The filler layer 6 is made of elastic rubber.

[0036] It should be noted that elastic rubber has high elasticity, which allows the cable to adapt well to deformation when bent, stretched, and twisted, avoiding breakage of the internal conductor or damage to the insulation layer 3. When subjected to external pressure or bending deformation, elastic rubber can quickly return to its original shape, which helps the cable maintain a good physical shape after long-term use and reduces cable damage caused by changes in the usage environment. In addition, elastic rubber has good compressive strength and can absorb impact and pressure when subjected to external force, avoiding damage to the internal conductor or insulation layer 3.

[0037] The waterproof layer 8 is a water-blocking strip, and the water-blocking strip overlaps and wraps around the outer surface of the wrapping layer 7.

[0038] It should be noted that the overlapping design of the water-blocking tape helps to form multiple waterproof barriers. When water attempts to penetrate, the water-blocking tape will prevent the water from spreading further through physical and chemical action. The overlapping structure can reduce the channels for water penetration and provide more reliable waterproof protection. The water-blocking tape usually uses water-absorbing and swelling materials. Once it comes into contact with water, it will expand and seal the outer layer of the cable, thereby preventing water from further penetrating into the cable interior, which greatly improves the sealing performance and effectiveness of the waterproof layer 8.
