Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to a friction-resistant and wear-resistant cable. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. Cables have many uses, primarily controlling installations, connecting devices, and transmitting power. Specialty cables are specialized cables designed for specific applications. They are resistant to high temperatures, acids and alkalis, and termites, and are used in applications such as ships, aircraft, and nuclear power plants. Specialty cables are a range of products with unique properties and structures. Compared to conventional wires and cables, which are used in large quantities and for a wide range of applications, they feature higher technical content, stricter operating conditions, smaller batch sizes, and higher added value.

[0003] Existing specialty cables typically use conventional insulation and sheath materials, such as ordinary polyethylene or polyvinyl chloride, which are prone to wear, scratches, and even rupture when faced with continuous friction.

[0004] To this end, a friction-resistant and wear-resistant cable is proposed. Utility Model Content

[0005] In view of the above problems, the present invention provides a friction-resistant and wear-resistant cable to solve the problems raised in the above background technology.

[0006] The technical solution of the utility model is:

[0007] A friction-resistant and wear-resistant cable includes a central conductor, both ends of which are provided with support frames, the outer surface between the two support frames is fixedly connected to an outer sheath, the outer surface of the central conductor is spirally woven with a plurality of inner shielding composite nets, and the inner wall of the outer sheath and the central conductor are filled with insulating foam.

[0008] During use, the support frames installed at both ends of the center conductor can ensure the stable position of the center conductor, avoid internal wear and tear due to vibration and displacement during current transmission, and ensure stable current transmission. The outer sheath is connected between the two support frames, which can fully resist external mechanical damage such as scratches and collisions, effectively protect the internal structure, and extend the service life of the cable. The spirally woven inner shielding composite mesh on the outer surface of the center conductor enhances the electromagnetic shielding effect while improving the mechanical strength of the center conductor, enabling it to withstand external pressure and friction and reduce internal damage. The insulating foam filled between the inner wall of the outer sheath and the center conductor can effectively isolate the current and ensure safe use. On the other hand, its buffering effect can absorb external impact energy, reduce vibration and friction inside the cable, and further enhance the wear resistance of the cable.

[0009] In a further technical solution, the support frame includes a wear-resistant sleeve, a mounting port, a thermal insulation sleeve, an outer insulation groove, and an inner sleeve. The mounting port is opened on the surface of the wear-resistant sleeve, the thermal insulation sleeve is fixed to the inner wall of the mounting port, the outer insulation groove is opened on the surface of the thermal insulation sleeve, and the insulating foam extends to the interior of the outer insulation groove. The inner sleeve is fixed to the inner wall of the outer insulation groove, and the outer surfaces of both ends of the central conductor are fixedly connected to the inner wall of the inner sleeve.

[0010] Through the above technical solution, the wear-resistant sheath is located at the outermost layer of the support frame, which can directly withstand external friction and scratches, effectively protect the internal structure, and reduce wear on internal components. The thermal insulation sleeve can block the external high temperature, avoid the adverse effects of high temperature on the internal structure and performance of the cable, and reduce material aging and wear caused by temperature changes. The outer insulation groove provides space for the extension of the insulating foam, enhances the insulation effect, and makes the cable safer and more reliable during use. The inner sheath is tightly connected to both ends of the center conductor, providing additional protection and fixation for the center conductor, further reducing the movement and wear of the center conductor.

[0011] In a further technical solution, two ends of the inner shielding composite net are fixed between opposite surfaces of the support frame.

[0012] Through the above technical solution, the displacement and loosening of the inner shielding composite net can be avoided during use, ensuring that it can always play a good electromagnetic shielding role and reduce the impact of external electromagnetic interference on the internal signal transmission of the cable. In addition, when the cable is subjected to external tension, extrusion, and twisting forces, the inner shielding composite net can withstand the force and reduce its own deformation and damage, thereby extending the overall service life and wear resistance of the cable.

[0013] In a further technical solution, the inner shielding composite mesh is composed of metal foil and steel wire, and each inner shielding composite mesh is spiral-shaped.

[0014] Through the above technical solution, the combination of metal foil and steel wire enables the inner shielding composite net to have both good electromagnetic shielding performance and mechanical strength. The metal foil can effectively block electromagnetic interference and ensure the accuracy and stability of signal transmission inside the cable. The steel wire enhances the tensile and compressive resistance of the inner shielding composite net, so that the cable can better withstand external forces.

[0015] In a further technical solution, the inner sheath and the outer sheath are made of the same material.

[0016] Through the above technical solution, the same material ensures that the inner and outer sheaths maintain consistent thermal expansion coefficients, allowing them to expand and contract synchronously when high temperatures change, reducing internal stress and potential damage caused by differences in thermal expansion and contraction, and improving the stability and reliability of the cable.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] Compared with the existing technology, the central conductor with support frames at both ends can ensure the overall support stability of the cable, reduce the wear caused by shaking and deformation, and when external impact occurs, the insulating foam inside the cable can reduce the wear effect of the impact on the central conductor. The inner shielding composite net enhances the overall strength of the cable and improves its wear resistance. Secondly, the wear-resistant sheath in the support frame initially blocks external friction, and the thermal insulation sleeve avoids the aggravation of wear caused by temperature changes. The outer insulation groove and inner sheath further enhance the insulation and wear resistance. BRIEF DESCRIPTION OF THE DRAWINGS

It can effectively resist erosion and friction from the external environment and protect the internal structure.
