Description

Technical Field

[0001] This invention relates to the field of cable technology, and in particular to a scratch-resistant cable. Background Technology

[0002] Cables are typically made up of several or groups of conductors (at least two conductors per group) twisted together. Each group of conductors is insulated from each other and is often twisted around a central conductor. The entire cable is covered with a highly insulating outer layer, giving it the characteristics of internal conductivity and external insulation. While cables currently possess properties such as abrasion resistance, providing some protection, their scratch resistance is not strong. Furthermore, some cables operate in harsh environments with frequent friction from other objects, or are subjected to traction when surrounded by sharp objects that are difficult to remove. These conditions can scratch the cable's outer protective layer. Since the cable's protective structure is located inside the protective layer, even if the internal structure can prevent further serious damage after the protective layer is damaged, the damage reduces the cable's insulation and protective capabilities, compromises its integrity, and shortens its lifespan. Summary of the Invention

[0003] To address the technical problem that existing cables have weak scratch resistance, leading to cable scratches and damage, reduced insulation and protection capabilities, compromised cable integrity, and decreased cable lifespan, this invention provides a scratch-resistant cable.

[0004] The technical solution provided by this invention is as follows:

[0005] This invention provides a scratch-resistant cable, comprising a protective layer, with multiple copper conductors arranged circumferentially on the inner side of the protective layer, each copper conductor being wrapped with an insulating layer on its outer side, and filler strips arranged between the multiple insulating layers. Filler units are arranged between the protective layer, the insulating layers, and the filler strips. The cable also includes a protective assembly disposed on the outer side of the protective layer. The protective assembly includes an outer protective assembly, an inner protective assembly, and a fixing assembly. The inner protective assembly is disposed inside the outer protective assembly and is in contact with the protective layer. Two sets of fixing assemblies are arranged axially symmetrically on the outer side of the outer protective assembly. The outer protective assembly includes a protective sleeve fitted onto the outer side of the protective layer, with multiple scratch-resistant protrusions fixedly connected to the outer side of the protective sleeve. These scratch-resistant protrusions are evenly distributed in a circumferential array on the outer side of the protective sleeve. The inner protective assembly includes a built-in airbag fixedly connected to the inner wall of the protective sleeve.

[0006] Preferably, a fixed top block is fixedly connected to the inner wall of the anti-scratch protrusion, and a connecting plate is fixedly connected to the bottom of the fixed top block, the connecting plate being slidably connected inside the protective kit.

[0007] Preferably, a built-in arc plate is fixedly connected to the bottom of the connecting plate, and the built-in arc plate is fixedly connected to the inner wall of the protective kit.

[0008] Preferably, a first spring sheet is fixedly connected to both sides of the built-in arc plate, and the first spring sheet is arranged in an abutting position with the protective layer.

[0009] Preferably, a tower-shaped compression spring is fixedly connected to the outer side of the fixed top block, the tower-shaped compression spring is arranged in contact with the protective kit, and the tower-shaped compression spring is arranged on the inner side of the anti-scratch protrusion.

[0010] Preferably, the outer wall of the protective kit is fixedly connected with oblique protrusions and gap protrusions, and the oblique protrusions and gap protrusions are densely distributed on the outer wall of the protective kit.

[0011] Preferably, the fixing component includes a fixing arc plate sleeved on the outside of the protective kit, a connector is fixedly connected to the outside of the fixing arc plate, and a second spring is fixedly connected to both ends of the fixing arc plate.

[0012] Preferred, one end of each of the two second spring pieces is fixedly connected to a side arc plate, and one end of the side arc plate is fixedly connected to a fastening side plate.

[0013] Preferably, a fixing bolt is inserted into the inside of the fastening side plate, and a fixing nut is threaded onto the outside of the fixing bolt.

[0014] Preferably, the protective kit has a first hook and a second hook fixedly connected to both ends, and the first hook and the second hook are configured to be interlocked.

[0015] The beneficial effects of the technical solution provided by this invention include at least the following:

[0016] In this invention, a protective assembly is used to provide double protection for the cable, both internally and externally. This allows sharp objects to come into contact with multiple anti-scratch protrusions, which protect the cable and prevent damage to the protective layer that could compromise cable integrity and reduce cable life. The special structure of the anti-scratch protrusions also gives them high hardness and good toughness. When a sharp object impacts the anti-scratch protrusion, the object compresses it and passes through its top surface, preventing the object from being blocked by the protrusion when it hits its side. This also prevents the anti-scratch protrusion from breaking due to continuous impact from sharp objects. Furthermore, the compression of the anti-scratch protrusions and the built-in airbags inside the protective assembly provide the cable with good impact resistance and scratch resistance.

However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0030] The technical solutions of the present invention will now be described with reference to the accompanying drawings. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0031] like Figures 1 to 10 As shown, an embodiment of the present invention provides a scratch-resistant cable, comprising: a protective layer 1 and a protective component. Multiple copper conductors 21 are arranged circumferentially on the inner side of the protective layer 1, and each copper conductor 21 is wrapped with an insulation layer 22. A filler strip 23 is arranged between the multiple insulation layers 22. A filler unit 24 is arranged between the protective layer 1, the insulation layer 22, and the filler strip 23. The protective component is sleeved on the outside of the protective layer 1 and includes an outer protective component, an inner protective component, and a fixing component. The inner protective component is disposed inside the outer protective component and is in contact with the protective layer 1. Two sets of fixing components are arranged axially symmetrically on the outside of the outer protective component. The outer protective component includes a protective sleeve 2 sleeved on the outside of the protective layer 1. The protective sleeve 2 is made of a relatively soft rubber material, and multiple anti-scratch protrusions 3 are fixedly connected to the outside of the protective sleeve 2. The top of the anti-scratch protrusion 3 is thicker, giving it higher hardness, while the four side walls are thinner, giving it a certain degree of toughness. Multiple anti-scratch protrusions 3 are evenly distributed in a circumferential array on the outside of the protective kit 2. A fixed top block 5 is fixedly connected to the inner wall of the anti-scratch protrusion 3. A connecting plate 6 is fixedly connected to the bottom of the fixed top block 5. The connecting plate 6 is slidably connected to the inside of the protective kit 2. The connecting plate 6 extends from the outside of the protective kit 2 into the inside of the protective kit 2. An internal arc plate 7 is fixedly connected to the bottom of the connecting plate 6. The internal arc plate 7 is fixedly connected to the inner wall of the protective kit 2. First spring pieces 8 are fixedly connected to both sides of the internal arc plate 7. The first spring pieces 8 are elastic structures and are set in contact with the protective layer 1. A tower-shaped compression spring 9 is fixedly connected to the outside of the fixed top block 5. The tower-shaped compression spring 9 is in contact with the protective kit 2 and is set inside the anti-scratch protrusion 3. The tower-shaped compression spring 9 is an elastic structure.

[0032] It should be noted that when a cable equipped with this device is impacted and scratched by a sharp object, the sharp object will come into contact with multiple anti-scratch protrusions 3. These protrusions 3 protect the cable, preventing damage to the protective layer and thus avoiding loss of cable integrity and reduced cable life. Furthermore, the special structural design of the anti-scratch protrusions 3 gives them both high hardness and good toughness. When an anti-scratch protrusion 3 impacts a sharp object, the sharp object compresses the anti-scratch protrusion 3, causing its four... Compression on one side causes the anti-scratch protrusion 3 to sink as a whole, allowing sharp objects to pass through the top surface of the anti-scratch protrusion 3. This prevents sharp objects from hitting the side of the anti-scratch protrusion 3 and being blocked by it. It also prevents the anti-scratch protrusion 3 from being damaged by the continuous impact of sharp objects. Because the top surface of the anti-scratch protrusion 3 is relatively thick, it can avoid being excessively scratched and punctured when sharp objects pass through the top surface of the anti-scratch protrusion 3. This improves scratch resistance and ensures that the device has a good service life.

[0033] When the anti-scratch protrusion 3 is compressed and sunk, it simultaneously drives the fixed top block 5 to descend, thereby compressing the tower-shaped compression spring 9. The elasticity of the fixed top block 5 buffers the impact force of sharp objects, thus reducing the damage to the anti-scratch protrusion 3. At the same time, when the fixed top block 5 descends, it drives the built-in arc plate 7 to descend through the connecting plate 6. Since the built-in arc plate 7 is connected to the inner wall of the protective kit 2, and the inner side of the protective kit 2 that overlaps with the anti-scratch protrusion 3 is hollowed out, and the material of the protective kit 2 is relatively soft, when the built-in arc plate 7 descends, it pulls some of the protective kit 2 around the built-in arc plate 7 to descend, thereby further lowering the anti-scratch protrusion 3. At the same time, the first spring 8 is compressed. The double compression of the tower-shaped compression spring 9 and the first spring 8 buffers the impact, reducing the damage from violent impacts, thus enabling the cable to withstand impacts.

[0034] Furthermore, there are certain gaps between the multiple anti-scratch protrusions 3 on the same horizontal and vertical lines, and the material of the protective kit 2 is relatively soft, so that the protective kit 2 can have a certain bending ability after being wrapped around the outside of the protective layer 1, thus allowing the protective layer 1 to still have good flexibility. At the same time, the protective kit 2 can be unfolded into a flat state through the gaps between the multiple anti-scratch protrusions 3 on the same vertical line, so that it is easy to wrap the protective layer 1 during installation.

[0035] Furthermore, the outer wall of the protective kit 2 is fixedly connected with oblique protrusions 10 and gap protrusions 11, which are densely distributed on the outer wall of the protective kit 2.

[0036] It should be noted that multiple oblique protrusions 10 and gap protrusions 11 are densely distributed obliquely on the outer wall of the protective kit 2 where the anti-scratch protrusions 3 are not installed. This allows the oblique protrusions 10 and gap protrusions 11 to protect this area, preventing small sharp objects from directly contacting the protective kit 2 and causing damage to the gaps between the multiple anti-scratch protrusions 3. At the same time, the oblique arrangement of the oblique protrusions 10 and gap protrusions 11 can protect against both vertical and horizontal scratches. Furthermore, the oblique state of the oblique protrusions 10 and gap protrusions 11 has a certain guiding ability, allowing sharp objects to slide along the outer side of the oblique protrusions 10 or gap protrusions 11 and contact the anti-scratch protrusions 3. Thus, the anti-scratch protrusions 3 provide good protection due to their excellent scratch resistance and impact resistance. Moreover, the oblique protrusions 10 and gap protrusions 11 are relatively short and have gaps between them, so they do not affect the ability of the protective kit 2 to bend and unfold flat.

[0037] Furthermore, the inner protective component includes a built-in airbag 4 fixedly connected to the inner wall of the protective kit 2. The inner side of the built-in airbag 4 is a closed space, and there is gas inside the built-in airbag 4, so as to keep the built-in airbag 4 in an inflated state.

[0038] It should be noted that the distribution of the built-in airbag 4 is the same as that of the anti-scratch protrusion 3, but the installation position of the built-in airbag 4 is offset from that of the anti-scratch protrusion 3. For the specific distribution position, please refer to [reference needed]. Figure 9 This design allows the anti-scratch protrusion 3 to sink normally to ensure scratch resistance and impact resistance. At the same time, when the protective kit 2 is impacted without the anti-scratch protrusion 3 installed, the built-in airbag 4 can provide support and cushion the impact with internal gas, so that the gaps of the anti-scratch protrusion 3 still have impact resistance.

[0039] Furthermore, the fixing component includes a fixing arc plate 12 sleeved on the outside of the protective kit 2. A connector 18 is fixedly connected to the outside of the fixing arc plate 12. There are two types of fixing arc plates 12, and the top of the two types of fixing arc plates 12 is provided with connectors 18 of different shapes. The two types of connectors 18 can be connected to the two types of fixing arc plates 12 by plugging them in. A second spring piece 13 is fixedly connected to both ends of the fixing arc plate 12. The second spring piece 13 is an elastic structure. A side arc plate 14 is fixedly connected to one end of each of the two second spring pieces 13. The inner sides of the fixing arc plate 12 and the side arc plate 14 are provided with grooves that are adapted to the contour of the oblique protrusion 10. A fastening side plate 15 is fixedly connected to one end of the side arc plate 14. A fixing bolt 16 is inserted into the inside of the fastening side plate 15. A fixing nut 17 is threaded on the outside of the fixing bolt 16. A first hook 19 and a second hook 20 are fixedly connected to both ends of the protective kit 2, respectively. The first hook 19 and the second hook 20 are set in a snap-fit ​​manner.

[0040] It should be noted that when installing the protective kit 2, the protective kit 2 is wound around the outside of the protective layer 1, and the fixing arc plate 12 is fitted onto the outer position of the protective kit 2 where the oblique protrusion 10 is installed, so that the oblique protrusion 10 enters the groove on the inner side of the fixing arc plate 12, thereby forming a snap-fit ​​between the fixing arc plate 12 and the oblique protrusion 10. When snapping the side arc plates 14 on both sides with the oblique protrusion 10, the side arc plates 14 on both sides can be flipped over, and the second spring 13 is stretched at the same time, so that the side arc plates 14 can be moved away from the oblique protrusion 10, and the side arc plates 14 can be slowly released, so that the oblique protrusion 10 can gradually enter the groove on the inner side of the side arc plate 14, thereby completing the snap-fit ​​between the fixing arc plate 12, the side arc plates 14 and the oblique protrusion 10, thereby passing through the oblique protrusion. 10 limits the fixed arc plate 12 and the side arc plate 14, preventing them from lateral displacement or rotation outside the protective kit 2, thus improving the stability of the connection between the fixed arc plate 12, the side arc plate 14 and the protective kit 2. After the two sets of fixed arc plates 12 and side arc plates 14 are sleeved on the outside of the protective kit 2, the upper and lower side arc plates 14 are brought closer to each other by fixing bolts 16 and fixing nuts 17, thereby clamping the protective kit 2. The inner side of the protective kit 2 with the oblique protrusion 10 is a built-in airbag 4. When clamped by the two sets of fixed arc plates 12, the built-in airbag 4 will be compressed, thereby increasing the friction between the multiple built-in airbags 4 and the protective layer 1, thus fixing the protective kit 2 to the outside of the protective layer 1.

[0041] Simultaneously, when the protective kit 2 is clamped and fixed, the two sides of the protective layer 1 will move closer to each other, thereby bringing the first hook 19 and the second hook 20 closer together. When the first hook 19 and the second hook 20 are in contact, the second hook 20 can be manually engaged with the inside of the first hook 19. Since the lengths of the first hook 19 and the second hook 20 are the same as those of the protective kit 2, the engagement of the first hook 19 and the second hook 20 can completely connect the two sides of the protective kit 2, thereby ensuring that the protective kit 2 can completely cover the protective layer 1. Since the fixing arc plate 12 is fixed to the protective kit 2 by being sleeved on the outside of the oblique protrusion 10, the installation position of the fixing arc plate 12 can be rotated arbitrarily when the protective kit 2 is fixed by the fixing arc plate 12. At the same time, in the weaker parts of the protective kit 2, the fixing arc plate 12 can be added to improve the firmness of the protective kit 2 on the outside of the protective layer 1.

[0042] Since the protective kit 2 is designed in sections, when protecting the protective layer 1 from scratches, the protective kit 2 only needs to be installed at the location on the protective layer 1 that needs protection. This improves the flexibility of protecting the protective layer 1, and the selectable protection method reduces the cost of protecting the protective layer 1. Furthermore, when the length of the protective layer 1 that needs protection is greater than the overall length of the protective kit 2, a corresponding number of protective kits 2 can be installed. Since there are two types of fixing arc plates 12, multiple protective kits 2 can be connected end-to-end by installing the two types of fixing arc plates 12 at the junction. Specifically, the connection between the two fixing arc plates 12 is completed by inserting the connector 18 at the top of the latter fixing arc plate 12 into the other connector 18. For details on the connection method and the outline of the two connectors 18, please refer to [reference needed]. Figure 10 .

[0043] In summary, the scratch-resistant cable designed in this invention can simultaneously provide the cable with scratch resistance and impact resistance without affecting its flexibility. Through the selective protection of the cable and the interconnection capability of the protective kit 2, the device can be installed according to the required protection position of the protective layer 1, thereby enabling the cable to have targeted protection, and the selectable setting can reduce the protection cost of the cable.

[0044] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:

[0045] In this embodiment of the invention, a protective component is used to provide double protection for the cable, both internally and externally. This allows sharp objects to come into contact with multiple anti-scratch protrusions 3, which in turn protect the protective layer 1, thus preventing damage to the protective layer 1. Furthermore, the special structural design of the anti-scratch protrusions 3 gives them both high hardness and good toughness. When the anti-scratch protrusions 3 collide with a sharp object, the sharp object compresses the anti-scratch protrusions 3 and passes through the top surface of the anti-scratch protrusions 3. This prevents the sharp object from being blocked by the anti-scratch protrusions 3 when it impacts the side of the anti-scratch protrusions 3, and also prevents the anti-scratch protrusions 3 from being damaged by continuous impact from sharp objects. The compression of the anti-scratch protrusions 3 and the built-in airbags 4 inside the protective kit 2 provide the cable with good impact resistance and scratch resistance.
