Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a high-strength cable that is resistant to aging. Background Technology

[0002] High-strength cables are typically used in applications requiring the resistance to significant mechanical stress and harsh environments. They are usually made of multi-strand flexible oxygen-free copper wire, a material with excellent electrical conductivity and flexibility, and are primarily used in power transmission, heavy machinery, and other special environments.

[0003] Referring to Chinese Patent Publication No. CN212032742U, published on November 27, 2020, a high-strength cable is disclosed, relating to the field of cable technology. It includes a conductor and a sheath layer surrounding the conductor. Multiple conductors are evenly arranged around an elastic post. A wear-resistant layer is provided between the sheath layer and the elastic post. An annular groove is formed around the periphery of the wear-resistant layer. Multiple annular grooves are spaced apart along the length of the wear-resistant layer. A buffer elastic element is sleeved within the annular groove. This invention improves the internal structure, making the cable less prone to breakage during prolonged bending, thus extending the cable's service life.

[0004] However, the aging resistance, wear resistance, mechanical strength, and signal transmission stability of existing high-strength aging-resistant cables need to be improved, as exemplified by the comparative patent mentioned above. Therefore, we propose an aging-resistant high-strength cable to address the aforementioned issues. Utility Model Content

[0013] 1. It is equipped with buffer holes. Multiple small buffer holes are opened inside the elastic column. The buffer holes can improve the buffer deformation capacity of the elastic column and help reduce the material, making the cable lighter. Multiple small buffer holes can reduce high frequency loss.

[0014] Furthermore, it can better control impedance, improve signal transmission quality and stable transmission, reduce reflection and distortion, optimize signal transmission path, reduce signal attenuation and distortion during transmission, and improve signal-to-noise ratio.

The intermediate layer is fixedly installed on the outside of the second inner insulation layer.

[0025] 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.

[0026] Please see Figures 1-5 The present invention provides the following technical solution:

[0027] Example 1: The stable signal transmission performance of existing high-strength cables needs improvement. To solve this technical problem, this example discloses the following technical content:

[0028] A high-strength cable resistant to aging includes a wire core 1, buffer holes 3, wear-resistant structure 8, and outer sheath 9. The wire core 1 is fixedly installed on an elastic post 2. Multiple small buffer holes 3 are opened inside the elastic post 2. A filler 4 is fixedly installed on the outside of the elastic post 2. A copper sheath 5 is fixedly installed on the outside of the filler 4. A first insulation layer 6 is fixedly installed on the outside of the copper sheath 5. A fireproof layer 7 is fixedly installed on the outside of the first insulation layer 6. The wear-resistant structure 8 is installed on the outside of the fireproof layer 7. The outer sheath 9 is installed on the outside of the wear-resistant structure 8.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, the elastic column 2 is a vulcanized rubber column, which has a certain strength and high elasticity. Multiple small buffer holes 3 are opened inside the elastic column 2. The buffer holes 3 can improve the buffer deformation capacity of the elastic column 2 and help reduce material, making the cable lighter. Multiple small buffer holes 3 can reduce high frequency loss and better control impedance, improve signal transmission quality. Through multiple small buffer holes 3, impedance can be better controlled to ensure stable signal transmission, reduce reflection and distortion. The design of multiple small buffer holes 3 can optimize the signal transmission path, reduce signal attenuation and distortion during transmission, and improve the signal-to-noise ratio.

[0030] Example 2: The wear resistance and mechanical strength of existing high-strength cables need to be improved. To solve this technical problem, this example discloses the following technical content:

[0031] like Figure 1 , Figures 3-5 As shown, the wear-resistant structure 8 includes a second insulating inner layer 801, an intermediate layer 802, and a wear-resistant outer layer 803. The intermediate layer 802 is fixedly installed on the outside of the second insulating inner layer 801. The intermediate layer 802 uses reinforcing fibers or a braided layer to improve the tensile strength of the high-strength cable. The wear-resistant outer layer 803 is fixedly installed on the outside of the intermediate layer 802. The wear-resistant outer layer 803 is made of polyurethane (PU) material. Polyurethane (PU) is a polymer material formed by the condensation reaction of polyols and polyisocyanates. It has high wear resistance, high elasticity, good weather resistance, good mechanical properties, and good low-temperature performance. The wear resistance of polyurethane is several times that of rubber, even... In some extreme working conditions, its wear resistance exceeds that of metal materials. Polyurethane rubber exhibits good elasticity over a wide temperature range. Even under long-term load, its compression set is very small. Polyurethane rubber has good UV resistance, ozone resistance, and oxidation resistance, and can be used in outdoor environments for a long time without aging. It has higher tensile strength and tear strength than ordinary rubber, and its Shore A hardness is between 20 and 98. Polyurethane rubber can still maintain good elasticity and mechanical properties in low-temperature environments. The wear-resistant structure 8 further improves the wear resistance and mechanical strength of high-strength cables through the combination of three different materials.

[0032] Example 3: The technical content disclosed in this example is a further improvement based on Example 1 above. The aging resistance of existing high-strength cables needs to be improved. To solve this technical problem, this example discloses the following technical content:

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the outer sheath 9 includes an outer sheath layer 901 and an inner sheath layer 902. The inner sheath layer 902 is fixedly installed inside the outer sheath layer 901, and a wear-resistant outer layer 803 is fixedly installed inside the inner sheath layer 902. The outer sheath layer 901 is made of modified natural rubber material. Modified natural rubber retains the high elasticity of natural rubber, and its wear resistance is significantly improved by adding specific fillers or modifiers. Through chemical modification or the addition of composite fillers, the aging resistance of modified natural rubber is enhanced, enabling high-strength cables to be used for a long time in harsh environments. The inner sheath layer... 902 uses nitrile rubber, a synthetic rubber copolymerized from butadiene and acrylonitrile. In terms of oil resistance, nitrile rubber exhibits extremely high tolerance to mineral oils, vegetable oils, and fuel oils. It also demonstrates excellent chemical resistance, resisting various chemicals such as acids, alkalis, and solvents. Furthermore, it possesses outstanding abrasion resistance, making it suitable for use in high-friction environments. It has a wide operating temperature range, from -40°C to 120°C, and boasts high tensile strength, good elasticity, and tear resistance. The outer sheath 9 is composed of two different materials, further enhancing the aging resistance of the high-strength cable.

[0034] Working principle: A fireproof layer 7 is fixedly installed on the inner side of the second insulating inner layer 801. The fireproof layer 7 is a synthetic mica tape layer with good electrical insulation, high temperature resistance and heat insulation. It can protect the inside of the cable from the influence of external high temperature for a certain period of time and has a good flame retardant effect.
