Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of cable-related technologies, and more specifically, to a low-voltage cable with a reinforced structure. Background Technology

[0002] In the field of power transmission, low-voltage cables are widely used for power connections in buildings, homes, and industrial equipment. With the increasing demand for electricity and the diversification of wiring scenarios, higher requirements are being placed on the reliability and ease of installation of low-voltage cables. However, traditional low-voltage cables have significant structural design flaws, making it difficult to meet the needs of modern, complex operating environments.

[0003] Existing low-voltage cables typically consist only of conductive cores and insulation layers, lacking effective reinforcement structures. Under frequent bending, pulling, or external impacts, the conductive cores are highly susceptible to breakage or damage, leading to circuit interruptions, affecting normal power transmission, and even posing safety hazards. Furthermore, to meet the requirements of neat wiring layouts within buildings, cables often need to be fixed to walls or other locations. However, traditional cables lack suitable external fixing structures, typically relying on cable ties, tape, and other auxiliary tools for fixation. This is not only cumbersome to install but also ineffective, leading to loosening and detachment after prolonged use, affecting line stability and hindering later inspection and maintenance. Therefore, developing a low-voltage cable that combines an internally reinforced anti-breakage structure with a convenient external fixing structure is of great significance for improving cable lifespan, ensuring power transmission stability, and simplifying the installation process. Utility Model Content

[0004] To overcome the aforementioned deficiencies, embodiments of this disclosure provide a low-voltage cable with a reinforced structure, solving the problem that existing low-voltage cables typically only contain conductive cores and insulation layers, lacking an effective reinforcing structure. Under frequent bending, pulling, or external impact, the conductive cores inside the cable are prone to breakage or damage, leading to circuit interruption.

[0005] According to one aspect, at least one embodiment of this disclosure provides a low-voltage cable with a reinforced structure, comprising: An outer protective layer and a middle plate, wherein the middle plate is disposed outside the outer protective layer; A fastening and fixing assembly is disposed on the middle plate; A supporting cable assembly is disposed inside the outer protective layer; The supporting cable assembly includes a wire core disposed inside the outer protective layer. A heat insulation layer is fitted inside the outer protective layer, and an anti-wear layer is fitted inside the heat insulation layer. A filler strip is disposed inside the anti-wear layer, and a plurality of support layers are disposed on the outer end face of the filler strip. The wire core is located between the filler strip and the support layers.

[0006] As a further technical solution, the tightening and fixing assembly includes several outer grooves, which are respectively opened at the top and bottom of the middle plate, and a fixing plate is rotatably connected to the outer grooves by a pin.

[0007] As a further technical solution, a sleeve plate is provided on the side surface of the fixing plate, and the sleeve plate is respectively fitted on the top and bottom of the outer protective layer. The fixing plate is filled with an anti-impact block, and the surface of the anti-impact block protrudes outward through the surface of the fixing plate.

[0008] As a further technical solution, the side surface of the anti-impact block is provided with a number of steel nails, the steel nails pass through the fixing plate and are located on the outside, and the surface of the fixing plate is provided with a pair of sleeve blocks, and an outer protective sleeve is inserted into the sleeve blocks.

[0009] As a further technical solution, the cross-section of the filler strip is cross-shaped, and the support layers are all arc-shaped transition structures.

[0010] As a further technical solution, the anti-impact block adopts a metal structure.

[0011] As a further technical solution, all the outer grooves are single-sided opening structures, and the fixing plate can only rotate in one direction by being limited by the outer groove.

[0012] As a further technical solution, the outer protective sleeve has an overall C-shaped structure, and the outer protective sleeve is tightly fitted to the surface of the sleeve plate.

[0013] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the cable support assembly effectively enhances the cable's resistance to breakage and compression through a multi-layer structural design. The conductor is tightly wrapped by a heat insulation layer, an anti-abrasion layer, a filler strip, and a support layer. The heat insulation layer blocks external heat, preventing the conductor from being damaged by high temperatures; the anti-abrasion layer resists external friction, extending the cable's service life; the cross-shaped filler strip provides buffer support and disperses pressure when the cable is compressed; the arc-shaped support layer forms a ring-shaped three-dimensional frame, dispersing stress when the cable is bent or pulled, preventing conductor breakage. The various structural layers work together to improve the cable's internal strength and ensure stable power transmission. Attached Figure Description

[0016] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0021] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] like Figures 1-3 As shown, a low-voltage cable with a reinforced structure is illustrated in one embodiment of this disclosure, comprising: An outer protective layer 1 and a middle plate 2, wherein the middle plate 2 is disposed outside the outer protective layer 1; A fastening and fixing component 4 is provided on the middle plate 2; A support cable assembly 3 is disposed inside the outer protective layer 1; The supporting cable assembly 3 includes a wire core 3-1, which is disposed inside the outer protective layer 1. A heat insulation layer 3-2 is fitted inside the outer protective layer 1. An anti-wear layer 3-3 is fitted inside the heat insulation layer 3-2. A filler strip 3-4 is disposed inside the anti-wear layer 3-3. A plurality of support layers 3-5 are disposed on the outer end face of the filler strip 3-4. The wire core 3-1 is located between the filler strip 3-4 and the support layers 3-5.

[0023] In some examples, a supporting cable assembly 3 is designed to enhance the cable's resistance to breakage and compression. The conductor 3-1, as the core component for power transmission, is tightly encased in a multi-layered protective structure. The heat insulation layer 3-2 effectively blocks external heat conduction, preventing damage to the conductor 3-1 due to high temperatures; the abrasion-resistant layer 3-3 resists external friction, extending the cable's service life. Filler strips 3-4 and support layers 3-5 tightly surround the conductor 3-1. The filler strips 3-4, made of highly elastic buffer material, provide cushioning support when the cable is subjected to external pressure, reducing the pressure on the conductor 3-1. Multiple support layers 3-5 are evenly distributed in a ring, forming a three-dimensional support frame. When the cable is bent or subjected to external tension, the support layers 3-5 disperse stress, preventing the conductor 3-1 from breaking. The various structural layers work together to significantly enhance the internal strength of the cable, ensuring stable and reliable power transmission.

[0024] like Figures 1-3 As shown in the figure, the fastening and fixing assembly 4 in this embodiment includes several outer grooves 4-1, which are respectively opened at the top and bottom of the middle plate 2. A fixing plate 4-2 is rotatably connected to the outer groove 4-1 by a pin. A sleeve plate 4-3 is provided on the side surface of the fixing plate 4-2. The sleeve plate 4-3 is respectively fitted on the top and bottom of the outer protective layer 1. An anti-impact block 4-4 is filled in the fixing plate 4-2. The surface of the anti-impact block 4-4 protrudes outward through the surface of the fixing plate 4-2. Several steel nails 4-5 are provided on the side surface of the anti-impact block 4-4. The steel nails 4-5 pass through the fixing plate 4-2 and are located on the outside. A pair of sleeve blocks 4-6 are provided on the surface of the fixing plate 4-2. An outer protective sleeve 4-7 is inserted into the sleeve blocks 4-6.

[0025] In some examples, a clamping fixing assembly 4 is designed to securely fix the cable to the wall. The outer groove 4-1 on the middle plate 2 provides a rotating connection base for the fixing plate 4-2. When it is necessary to fix the cable, the fixing plate 4-2 is rotated by the pin, so that the sleeve plate 4-3 fits against the outer protective layer 1, tightly securing the cable. The impact-resistant block 4-4 is filled inside the fixing plate 4-2. Its outward protruding design enhances the impact resistance of the fixing plate 4-2, and it can be hammered with tools such as a hammer. The steel nail 4-5 protrudes from the side surface of the impact-resistant block 4-4 and can be directly driven into the wall by hammering, achieving a secure connection between the cable and the wall. When the fixing plate 4-2 is flush with the middle plate 2, the sleeve plate 4-3 can maintain the tightness of the cable. The combination of the sleeve block 4-6 and the outer protective sleeve 4-7 further strengthens the fixing structure. The outer protective sleeve 4-7 fits inside the sleeve block 4-6, which not only prevents the cable from falling off, but also protects the cable from damage during the nailing process. The entire fixing assembly achieves a tight connection between the cable and the wall through multiple fixing methods, making installation convenient and providing a stable fixing effect, effectively solving the problem of difficult traditional cable fixing.

[0026] For example, such as Figure 1 As shown, the cross-section of the filler strip 3-4 is cross-shaped, and the support layers 3-5 are all arc-shaped transition structures.

[0027] In some examples, the filler strip 3-4 adopts a cross-shaped cross-section structure, which can form a stable support in the annular space of the heat insulation layer 3-2 and the abrasion-resistant layer 3-3. The four extended sides can evenly distribute the external pressure, avoid stress concentration on the core 3-1, and effectively improve the cable's resistance to compression. The arc-shaped transition structure of the support layer 3-5 can increase the fit effect. When the cable is bent, the arc-shaped structure can make the support force transition smoothly, further enhancing the cable's resistance to bending and ensuring the safety and stability of the core 3-1.

[0028] For example, such as Figure 2 As shown, the anti-impact block 4-4 is made of metal.

[0029] In some examples, the impact-resistant block 4-4 is made of metal, which provides excellent resistance to hammering due to its high strength. It allows steel nails 4-5 to be driven firmly into the wall, ensuring the stability of the cable connection and protecting against everyday impacts and scratches, thus extending the lifespan of the mounting components.

[0030] For example, such as Figure 2 As shown, the outer grooves 4-1 are all single-sided opening structures, and the fixing plate 4-2 can only rotate in one direction due to the limitation of the outer grooves 4-1.

[0031] In some examples, the single-sided opening structure of the outer groove 4-1 restricts the rotation direction of the fixing plate 4-2. Through the limiting effect, the fixing plate 4-2 can only rotate in one direction. This design facilitates quick installation by operators and avoids incorrect rotation of the fixing plate 4-2 due to misoperation. At the same time, after the cable is fixed, it prevents the fixing plate 4-2 from rotating in the opposite direction and loosening, ensuring that the sleeve plate 4-3 always tightly fits the outer protective layer 1, maintaining the reliability and stability of the cable fixing.

[0032] For example, such as Figure 3 As shown, the outer protective sleeve 4-7 has an overall C-shaped structure, and the outer protective sleeve 4-7 is tightly attached to the surface of the sleeve plate 4-3.

[0033] In some examples, the outer protective sleeve 4-7 has an overall C-shaped structure. This design allows it to fit snugly against the surface of the sleeve plate 4-3, forming a semi-enclosed protection. During installation, the C-shaped outer protective sleeve 4-7 can quickly snap into the sleeve block 4-6, making the operation convenient. It also effectively wraps around the connection between the steel nail 4-5 and the fixing plate 4-2, enhancing the friction between the sleeve plate 4-3 and the outer protective layer 1, further strengthening the cable's fixation effect, and ensuring the cable is securely installed on the wall.

[0034] In practical use: Outer grooves 4-1 are formed at the top and bottom of the middle plate 2. A fixed plate 4-2 is rotatably connected to the outer grooves 4-1 via pins. Sleeves 4-3 are installed on the side surface of the fixed plate 4-2, respectively fitted onto the top and bottom of the outer protective layer 1. Anti-impact blocks 4-4 are filled inside the fixed plate 4-2. Steel nails 4-5 on the side surface of the anti-impact blocks 4-4 pass through the fixed plate 4-2. An outer protective sleeve 4-7 is inserted into the sleeve 4-6 on the surface of the fixed plate 4-2. For the cable portion, the outer protective layer 1 serves as the outermost layer, wrapping the entire cable. Inside the outer protective layer 1, a heat insulation layer 3-2 and an anti-wear layer 3-3 are sequentially installed. A cross-shaped filler strip 3-4 is installed inside the anti-wear layer 3-3. Several arc-shaped support layers 3-5 are installed on the outer end face of the filler strip 3-4. The wire core 3-1 is located between the filler strip 3-4 and the support layers 3-5. When in use, rotate the fixing plate 4-2 to tighten the sleeve plate 4-3 onto the outer protective layer 1, and use a hammer to drive the steel nail 4-5 into the wall to fix the cable. Finally, insert the outer protective sleeve 4-7 into the sleeve block 4-6 to enhance the protective effect. The heat insulation layer 3-2, the abrasion-resistant layer 3-3, the filler strip 3-4, and the support layer 3-5 inside the cable together protect the core 3-1.
