Description

Technical Field

[0001] This utility model belongs to the field of environmentally friendly low-smoke cable technology, and in particular relates to ultra-low temperature resistant environmentally friendly low-smoke cables. Background Technology

[0002] Environmentally friendly low-smoke cables are a type of wire and cable with characteristics such as low smoke, halogen-free, low toxicity, and flame retardancy. They are widely used in places with high requirements for safety and environmental protection. They do not contain halogens (such as chlorine, bromine, etc.), produce very little smoke when burning, and do not release corrosive gases. They are suitable for densely populated or enclosed spaces.

[0003] While existing environmentally friendly low-smoke cables can meet users' needs to a certain extent, they still have some shortcomings in actual use. For example, existing environmentally friendly low-smoke cables sometimes need to be used in low-temperature environments, which have a significant impact on the cables. Low temperatures affect the bending performance of the cables, and bending the cables in low-temperature environments can easily cause cracks on their surface. Moreover, existing cables often need to be fixed to walls to prevent them from becoming tangled and affecting their use, but it is often inconvenient to fix the cables to walls, which also affects their use.

[0004] Therefore, we provide ultra-low temperature resistant, environmentally friendly, and low-smoke cables. Utility Model Content

[0005] The purpose of this invention is to provide ultra-low temperature resistant, environmentally friendly, and low-smoke cables, aiming to solve the aforementioned technical problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the heating copper wire can heat the cable and enhance its cold resistance.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 and Figure 2 As shown, the ultra-low temperature resistant, environmentally friendly, and low-smoke cable provided in this embodiment includes a wear-resistant rubber jacket 1. Both sides of the surface of the wear-resistant rubber jacket 1 are provided with recessed textures 2. A flame-retardant layer 3 is provided inside the wear-resistant rubber jacket 1. A shielding layer 4 is provided inside the flame-retardant layer 3. A support frame 15 is provided inside the shielding layer 4. Multiple wire cores 5 are inserted inside the support frame 15. An insulating sleeve 6 is provided on the outside of the wire cores 5.

[0028] In this embodiment, the wear-resistant rubber jacket 1 is made of high-density polyethylene, giving the entire cable excellent wear resistance. The surface grooves 2 enhance the cable's anti-slip properties and wear resistance. Furthermore, when the wear-resistant rubber jacket 1 is compressed, it can be squeezed into the grooves 2, enhancing its compressive strength. The flame-retardant layer 3 is extruded from halogen-free, low-smoke, flame-retardant polyolefin, giving the cable excellent flame-retardant properties. The shielding layer 4 is braided from tin-plated copper conductors, providing excellent shielding and preventing damage to the cable. The support frame 15 provides excellent support and compressive strength, preventing damage to the wire core 5. The insulating sleeve 6 is made of silicone rubber, providing excellent insulation for the wire core 5 and preventing cable leaks.

[0029] like Figure 1 and Figure 2 As shown, the ultra-low temperature resistant, environmentally friendly, low-smoke cable provided in this embodiment has a heating structure on the outside of the insulating sleeve 6. The heating structure includes a thermally conductive filler 10, which is filled inside the shielding layer 4. Multiple heating copper wires 11 are inserted inside the thermally conductive filler 10. A thermally conductive insulating sleeve 126 is fitted on the outside of the heating copper wires 11. A heat insulation layer 13 is fitted on the outside of the thermally conductive filler 10. A textile braided layer 14 is fitted on the outside of the heat insulation layer 13. An insulation filler 16 is provided on the outside of the textile braided layer 14. The insulation filler 16 is located on the outside of the support frame 15. Multiple reinforcing wires 17 are inserted inside the insulation filler 16.

[0030] In this embodiment, the heating copper wire 11 can heat the cable and enhance its cold resistance. Under the action of the thermally conductive filler 10, it is easy to conduct heat to the wire core 5, which enhances the thermal conductivity. Under the action of the heat insulation layer 13, the heat generated by heating can be prevented from being lost, which enhances the cold resistance. Under the action of the heat insulation filler 16, the cable as a whole has a good heat insulation effect. At the same time, under the action of the textile braided layer 14 and the reinforcing wire 17, the cable as a whole has good tensile toughness and extends the service life of the cable as a whole.

[0031] like Figure 3 and Figure 4 As shown, the ultra-low temperature resistant, environmentally friendly, and low-smoke cable provided in this embodiment has a fixing structure on the outer side of the wear-resistant rubber jacket 1. The fixing structure includes a connecting seat 7, which is disposed on one side of the surface of the wear-resistant rubber jacket 1. A moving groove 19 is provided inside the connecting seat 7, and limit racks 21 are provided at both ends of one side of the inner wall of the moving groove 19. A fixing frame is movably fitted on the surface of the connecting seat 7. Assembly grooves 9 are provided on both sides of one end of the fixing frame. A clamping bolt 24 is movably inserted in the middle of the fixing frame. A rotating block is provided at one end of the clamping bolt 24, and the other end of the clamping bolt 24 is movably inserted. A locking toothed plate 22 is rotatably mounted in the movable groove 19. Both ends of the locking toothed plate 22 are engaged with the limiting toothed strip 21. The width of the locking toothed plate 22 is equal to the width of the movable groove 19. A compression spring 23 is sleeved on the surface of the clamping bolt 24. Both ends of the compression spring 23 are fixedly connected to the locking toothed plate 22 and the fixing clamp 8, respectively. An insertion port 18 is opened on the surface of the movable groove 19. The width of the insertion port 18 is equal to that of the locking toothed plate 22. Sliding grooves 20 are opened on both sides of the surface of the connecting seat 7. Sliding blocks are fixedly installed on both sides of one side of the inner wall of the fixing clamp 8. The sliding blocks are slidably connected to the sliding grooves 20.

[0032] In this embodiment, the user places the fixing clip 8 on the surface of the cable, and the limiting tooth plate is inserted into the moving groove 19 through the insertion port 18. The locking tooth plate 22 moves along the moving groove 19. When the fixing clip 8 moves to the fixed position, the user rotates the compression spring 23, and the compression spring 23 drives the locking tooth plate 22 to move, so that the locking tooth plate 22 is engaged with the limiting tooth 21, so that the fixing clip 8 cannot move on the surface of the cable. The fixing clip 8 can be fixed to the wall through the mounting groove 9, so that the cable can be well fixed.
