Description
Technical Field
[0001] This utility model belongs to the field of wire and cable technology, specifically a cable with a wear-resistant protective layer. Background Technology
[0002] Cables are typically made up of several or groups of conductors twisted together in a rope-like structure. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer, giving it the characteristics of being internally energized and externally insulated.
[0003] They can be mainly divided into power cables, control cables, communication cables, and special cables, and are widely used in power systems, communication systems, construction, transportation, industrial automation, and new energy fields.
[0004] Through long-term observation, it has been found that in the installation and use of existing cables, external fixing parts (such as clips, cable ties, etc.) are usually required to directly contact the outer layer of the cable and apply compressive force to achieve the positioning and fixation of the cable. However, the compressive force of the external fixing parts will act on the outer wall of the cable for a long time. With the increase of the usage time, the outer wall of the cable is prone to severe wear due to continuous compression and friction, and may even have inward deformation problems. Therefore, a cable with a wear-resistant protective layer is proposed to address the above problems. Summary of the Invention
[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a cable with a wear-resistant protective layer.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The cable with a wear-resistant protective layer of this utility model includes a battery core, an inner layer is provided on the outer wall of the battery core, and an outer layer is installed on the outer wall of the inner layer; a protective layer is provided on the outer wall of the outer layer, and a first connecting plate and a second connecting plate are fixedly connected to both ends of the protective layer. A rotating drum is rotatably connected to the inner wall of the first connecting plate, and a locking rod is fixedly connected to the inner wall of the second connecting plate. Multiple elastic ropes are fixedly connected to the outer wall of the rotating drum, and a buckle is fixedly connected to the bottom of the elastic rope. The buckle and the locking rod are engaged.
[0007] Preferably, a friction film is fixed to the inner wall of the protective layer, and a friction pad is fixed to the inner wall of the buckle.
[0008] Preferably, a fireproof layer is fixed to the inner wall of the outer layer.
[0009] Preferably, a buffer layer is fixed to the inner wall of the outer layer, and the buffer layer is located on the outer ring of the fireproof layer.
[0010] Preferably, the outer wall of the outer layer is roughened.
[0011] The beneficial effects of this utility model are: This utility model provides a cable with a wear-resistant protective layer. By splicing the protective layer into a circle, the situation where the external fixed workpiece directly squeezes the outer wall of the outer layer during installation can be avoided. This solves the problem of long-term fixation causing significant wear on the outer wall of the outer layer and leading to inward indentation. It effectively protects the structural integrity of the outer layer and makes the cable fixing operation more in line with its own structural characteristics.
[0012] This utility model provides a cable with a wear-resistant protective layer. The friction film enhances the friction between the protective layer and the outer layer, preventing the protective layer from sliding or shifting on the cable surface and improving the positioning stability of the protective layer. The friction pad increases the friction after the buckle and the buckle are engaged, preventing the buckle from accidentally falling off and further ensuring the reliability of the fixed state of the protective layer.

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0017] Specific implementation examples are given below.
[0018] like Figure 1-4As shown, a cable with a wear-resistant protective layer includes a battery core 1. An inner layer 11 is disposed on the outer wall of the battery core 1, and an outer layer 12 is installed on the outer wall of the inner layer 11. A protective layer 13 is disposed on the outer wall of the outer layer 12. A first connecting plate 14 and a second connecting plate 15 are fixedly connected to both ends of the protective layer 13. A rotating drum 16 is rotatably connected to the inner wall of the first connecting plate 14, and a locking rod 17 is fixedly connected to the inner wall of the second connecting plate 15. Multiple elastic ropes 18 are fixedly connected to the outer wall of the rotating drum 16, and a buckle 19 is fixedly connected to the bottom of each elastic rope 18. The buckle 19 and the locking rod 17 are engaged. The basic structure of this cable is that the inner layer 11 is disposed on the outer wall of the battery core 1, and the outer layer 12 is installed on the outer wall of the inner layer 11. When it is necessary to fix the cable position, the protective layer 11 is first... 3. Unfold and move the protective layer 13 to the installation point of the cable, and then splice the unfolded protective layer 13 into a circle so that it contacts the outer wall of the outer layer 12. Then, operate the rotating drum 16 connected to the inner wall of the first connecting plate 14. Use the elastic rope 18 fixed to the outer wall of the rotating drum 16 to engage the buckle 19 fixed to the bottom of the elastic rope 18 with the clamp rod 17 fixed to the inner wall of the second connecting plate 15 to complete the fixing of the protective layer 13. This step, by splicing the protective layer 13 into a circle, can avoid the situation where the external fixed workpiece directly squeezes the outer wall of the outer layer 12 for installation. It solves the problem of long-term fixing causing large wear on the outer wall of the outer layer 12 and causing it to dent inward. It effectively protects the structural integrity of the outer layer 12, and at the same time makes the fixing operation of the cable more in line with its own structural characteristics.
[0019] like Figure 1-4 As shown, a friction film 2 is fixed to the inner wall of the protective layer 13, and a friction pad 21 is fixed to the inner wall of the buckle 19. When the protective layer 13 contacts the outer layer 12, the friction film 2 will directly adhere to the outer wall of the outer layer 12. At the same time, when the buckle 19 engages with the lever 17, the friction pad 21 will contact the surface of the lever 17. This step enhances the friction between the protective layer 13 and the outer layer 12 through the friction film 2, preventing the protective layer 13 from sliding and shifting on the cable surface, and improving the positioning stability of the protective layer 13. The friction pad 21 increases the friction after the buckle 19 engages with the lever 17, preventing the buckle 19 from accidentally falling off, and further ensuring the reliability of the fixed state of the protective layer 13.
[0020] like Figure 1-4 As shown, a fireproof layer 3 is fixed to the inner wall of the outer layer 12. When an open flame or high-temperature heat source appears in the environment where the cable is located, the fireproof layer 3 is located between the outer layer 12 and the inner layer 11 and the battery core 1, directly blocking the transmission of open flame and high temperature to the inside. This step solves the problem that the cable is easily ignited in a fire hazard environment and the internal battery core 1 is easily damaged by high temperature, thus improving the fire safety performance of the cable.
[0021] like Figure 1-4 As shown, a buffer layer 4 is fixed to the inner wall of the outer layer 12, and the buffer layer 4 is located on the outer ring of the fireproof layer 3. When the cable is subjected to external forces such as collision or compression, the external force is first applied to the outer layer 12 and then transmitted to the buffer layer 4. This step solves the problem that the internal structure of the cable is easily damaged when subjected to external impact, and improves the cable's impact and compression resistance.
[0022] like Figure 1-4 As shown, the outer wall of the outer layer 12 is roughened. By setting the outer wall of the outer layer 12 to a rough surface, when the protective layer 13 comes into contact with the outer layer 12, the rough outer wall surface will form a tighter contact with the friction film 2 on the inner wall of the protective layer 13. This step solves the problem of relative sliding after the protective layer 13 and the outer layer 12 are attached. At the same time, the rough surface also improves the basic wear resistance of the outer layer 12 itself, reducing the wear of the outer layer 12 in daily use.
[0023] Working principle: First, the basic structure of the cable consists of an inner layer 11 on the outer wall of the battery core 1, and an outer layer 12 installed on the outer wall of the inner layer 11. When it is necessary to fix the cable position, the protective layer 13 is first unfolded and moved to the installation point of the cable. Then, the unfolded protective layer 13 is spliced into a circle so that it contacts the outer wall of the outer layer 12. Subsequently, the rotating drum 16 connected to the inner wall of the first connecting plate 14 is operated. Using the elastic rope 18 fixed to the outer wall of the rotating drum 16, the buckle 19 fixed to the bottom of the elastic rope 18 is engaged with the clamp 17 fixed to the inner wall of the second connecting plate 15, thus completing the fixation of the protective layer 13. A friction film 2 is fixed to the inner wall of the protective layer 13, and a friction pad 21 is fixed to the inner wall of the buckle 19. When the protective layer 13 contacts the outer layer 12, the friction film 2 will directly... When the outer wall of the outer layer 12 is attached to the outer wall, and the buckle 19 is engaged with the clamp 17, the friction pad 21 will contact the surface of the clamp 17. The fireproof layer 3 is fixed to the inner wall of the outer layer 12. When there is an open flame or high temperature heat source in the environment where the cable is located, the fireproof layer 3 is located between the outer layer 12 and the inner layer 11 and the core 1 of the internal structure, directly blocking the transmission of open flame and high temperature to the inside. The buffer layer 4 is fixed to the inner wall of the outer layer 12, and the buffer layer 4 is located on the outer ring of the fireproof layer 3. When the cable is subjected to external collision, compression or other external forces, the external force is first applied to the outer layer 12 and then transmitted to the buffer layer 4. The outer wall of the outer layer 12 is set as a rough surface. When the protective layer 13 contacts the outer layer 12, the rough outer wall surface will form a tighter contact with the friction film 2 on the inner wall of the protective layer 13.
[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
