Description
Technical Field
[0001] This utility model relates to the field of cable technology, and in particular to a fireproof rubber-sheathed cable with a fiber shielding anti-interference structure. Background Technology
[0002] With the rapid development of industries such as power and communications, the performance requirements for cables are becoming increasingly stringent. Traditional cables have shortcomings in terms of interference resistance and fire resistance, making it difficult to meet the needs of modern industry and daily life. For example, traditional cables often use metal braided shielding layers, which are susceptible to electromagnetic interference, affecting signal transmission quality. In addition, the fire resistance of the sheath materials of traditional cables is limited, making them easily combustible in a fire and posing a safety hazard.
[0003] Therefore, it is necessary to design a fireproof rubber-sheathed cable with a fiber-shielded anti-interference structure. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fireproof rubber-sheathed cable with a fiber-shielded anti-interference structure.
[0005] The technical solution of this utility model is: a fireproof rubber-sheathed cable with a fiber shielding anti-interference structure, comprising a cable core, an insulation layer, a shielding layer, a fireproof layer and a protective layer arranged sequentially from the inside to the outside; the shielding layer is a conductive fiber shielding layer; the protective layer is a rubber layer.
[0006] The cable core is composed of a tensile core at the center and multiple conductive cores evenly distributed on the outside of the tensile core, twisted together.
[0007] An elastic filler layer is provided between the cable core layer and the insulation layer.
[0008] The insulating layer is XLPE or EPR.
[0009] The conductive fiber shielding layer is woven from carbon fiber or metal fiber, and its coverage is greater than 90%.
[0010] The fireproof layer is made of ceramicized silicone rubber and has a thickness of not less than 2mm.
[0011] The surface of the rubber layer is covered with anti-slip textured patterns.
[0012] The present invention adopts the above technical solution and has the following beneficial effects: (1) The present invention uses conductive fiber as a shielding layer to replace the traditional metal shielding layer, which has the advantages of being lightweight, flexible and anti-interference. In addition, a fireproof layer is provided to provide better fireproof performance.
[0013] (2) The cable core of this utility model is made of a tensile core in the center and multiple conductive cores evenly distributed on the outside of the tensile core, which significantly improves the tensile strength of the cable, enabling it to withstand greater mechanical stress and is suitable for complex environments and long-distance laying.
[0014] (3) The insulation layer of this utility model is made of XLPE or EPR, which makes the cable have excellent insulation performance and heat resistance, effectively prevents current leakage, and ensures the stable operation of the cable in high temperature environment.
[0015] (4) An elastic filling layer is provided between the cable core layer and the insulation layer of this utility model. The design can not only buffer the influence of external stress on the cable core, but also improve the overall structural stability of the cable and extend its service life.
[0016] (5) The surface of the rubber layer of this utility model is distributed with anti-slip ridges; this design not only improves the anti-slip performance of the cable and facilitates installation and fixing, but also enhances the wear resistance of the outer sheath, enabling it to adapt to more complex usage environments. Attached Figure Description
[0017] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0018] Figure 1 This is a schematic diagram of the structure of this utility model.
[0019] The labels in the attached diagram are:
[0020] Cable core 1, tensile core 11, conductive core 12, insulation layer 2, shielding layer 3, fireproof layer 4, protective layer 5, elastic filler layer 6, anti-slip texture 7, metal tensile core 8. Detailed Implementation
[0021] (Example 1)
[0022] See Figure 1 This embodiment of a fireproof rubber-sheathed cable with a fiber shielding anti-interference structure includes a cable core 1, an insulation layer 2, a shielding layer 3, a fireproof layer 4, and a protective layer 5 arranged sequentially from the inside out; the shielding layer 3 is a conductive fiber shielding layer 3; and the protective layer 5 is a rubber layer.
[0023] Furthermore, the cable core 1 is formed by twisting together a tensile core 11 at the center and multiple conductive cores 12 evenly distributed on the outside of the tensile core 11; this significantly improves the tensile strength of the cable, enabling it to withstand greater mechanical stress and making it suitable for complex environments and long-distance laying; furthermore, the diameter of the tensile core 11 is 0.6 to 0.8 times that of the conductive core 12, thereby making the conductive core 12 and the tensile core 11 twisted more tightly.
[0024] Furthermore, an elastic filler layer 6 is provided between the cable core 1 layer and the insulation layer 2; this not only buffers the impact of external stress on the cable core 1, but also improves the overall structural stability of the cable and extends its service life.
[0025] Furthermore, the insulation layer 2 is XLPE or EPR, which gives the cable excellent insulation performance and heat resistance, effectively prevents current leakage, and ensures stable operation of the cable in high-temperature environments.
[0026] Furthermore, the conductive fiber shielding layer 3 is woven from carbon fiber or metal fiber, and its coverage is greater than 90% to ensure that the cable has good shielding performance and improve transmission efficiency. Replacing the traditional metal shielding layer 3 with the conductive fiber shielding layer 3 not only reduces the use of metal materials and lowers the weight of the cable, but is also more environmentally friendly, in line with the development trend of green manufacturing.
[0027] Furthermore, the fireproof layer 4 is made of ceramicized silicone rubber with a thickness of not less than 2mm. Using ceramicized silicone rubber as the fireproof layer 4 forms a ceramic protective layer 5 at high temperatures, which has better fireproof and heat insulation performance.
[0028] Furthermore, the surface of the rubber layer is distributed with anti-slip textures 7, which not only improves the cable's anti-slip performance and facilitates installation and fixation, but also enhances the wear resistance of the outer sheath, enabling it to adapt to more complex usage environments. Furthermore, the anti-slip textures 7 are elongated protrusions evenly distributed along the cable's length on the outer side of the protective sheath. These elongated protrusions are encased in a metal tensile core 8, which not only further improves the overall tensile strength of the cable but also makes the cable's protective layer 5 more difficult to damage, thus improving the cable's safety in use.
[0029] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
