Description

Technical Field

[0001] This utility model relates to the field of low-voltage cable technology, specifically a low-voltage cable with a buffer function. Background Technology

[0002] Low-voltage cables, as an important component of power transmission systems, are widely used in various buildings, industrial production, and daily life scenarios. They bear the critical task of stably transmitting low-voltage power to various power terminals. In actual use, low-voltage cables face many unexpected situations, among which external force damage is particularly prominent. During daily installation, laying, and use, low-voltage cables inevitably suffer from various external forces. During construction, cables may be damaged by pulling, twisting, or other operations. In the operating environment, cables may be squeezed or torn by factors such as building settlement and equipment vibration. Traditional low-voltage cables often lack effective coping mechanisms when facing these external forces. The structural design of ordinary cables is insufficient to protect the internal conductors under torsional forces, and the internal circuits are easily damaged due to excessive torsional stress, leading to power transmission interruption. At the same time, when subjected to compression or stretching, cables also lack a buffer structure for external forces, which can easily cause permanent deformation, thereby affecting their electrical performance and service life. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a low-voltage cable with a buffer function. The rubber ring and the arc plate work together to effectively absorb and disperse torsional force, enhancing the cable's anti-torsion ability. The concave strips and convex strips of the first and second reset devices cooperate with each other to elastically deform and buffer external forces when the cable is squeezed or stretched, and automatically reset after the force disappears, preventing the cable from undergoing permanent deformation.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-voltage cable with a buffer function, comprising a conductor wire, an insulating sleeve fixedly connected to the outer wall of the conductor wire, and a protective device, comprising an anti-torsion device, a first reset device fixedly connected to the outer wall of the anti-torsion device, a second reset device fixedly connected to the outer wall of the anti-torsion device, and a protective sleeve fixedly connected to the outer wall of the anti-torsion device, the protective device being used to reduce impact force and protect the conductor wire;

[0007] Preferably, the anti-torsion device includes a rubber ring, an arc-shaped plate fixedly connected to the outer wall of the rubber ring, a support block fixedly connected to one end of the arc-shaped plate, and a connecting block fixedly connected to the other end of the arc-shaped plate. The outer wall of the support block is fixedly connected to the outer side wall of the insulating sleeve, and the outer wall of the connecting block is fixedly connected to the inner side wall of the sheath. The rubber ring of the anti-torsion device deforms and absorbs energy when the cable is torsion, reducing the torsional stress on the conductor. The arc-shaped plate, by virtue of its shape and elasticity, bends with the rubber ring to disperse the torsional force. The two work together to enhance the cable's anti-torsion capability.

[0008] Preferably, the first reset device includes a first collar, the side wall of which is fixedly connected with a concave strip, the outer wall of which is fixedly connected with the side wall of the connecting block, and the outer wall of the concave strip is in contact with the outer wall of the insulating sleeve.

[0009] Preferably, the second reset device includes a second collar, the side wall of which is fixedly connected with an outwardly protruding strip. The outer wall of the second collar is fixedly connected to the outer wall of the support block. The outer wall of the outwardly protruding strip is in contact with the side wall inside the sheath. When the cable is squeezed or stretched, the inner concave strip and the outer protruding strip of the first and second reset devices interact to generate elastic deformation, absorb energy, and buffer external force. After the external force disappears, the collar relies on its own elasticity to drive the concave and protruding strips to reset, so that the cable returns to its original shape and avoids permanent deformation.

[0010] (III) Beneficial Effects

[0011] This invention provides a low-voltage cable with a buffer function. It has the following beneficial effects:

[0012] (I) The low-voltage cable uses the rubber ring of the anti-torsion device to deform and absorb energy when the cable is torsion, thereby reducing the torsional stress on the conductor. The arc plate, with its shape and elasticity, bends with the rubber ring to disperse the torsional force. The two work together to enhance the cable's anti-torsion ability, effectively reduce the risk of internal circuit damage due to torsion, and ensure the stable operation of the cable.

[0013] (ii) When the low-voltage cable is squeezed or stretched, the inner concave strip and outer convex strip of the first and second reset devices interact to generate elastic deformation, absorb energy and buffer external force. After the external force disappears, the collar drives the concave and convex strips to reset by its own elasticity, so that the cable returns to its original shape, avoids permanent deformation and extends the service life of the cable.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a low-voltage cable with a buffer function, including a conductor 1, an insulating sleeve 2 fixedly connected to the outer wall of the conductor 1, and a protective device 3, the protective device 3 including an anti-torsion device 31, a first reset device 32 fixedly connected to the outer wall of the anti-torsion device 31, a second reset device 33 fixedly connected to the outer wall of the anti-torsion device 31, and a wrapping sleeve 4 fixedly connected to the outer wall of the anti-torsion device 31. The protective device 3 is used to reduce impact force and protect the conductor 1.

[0022] The anti-torsion device 31 includes a rubber ring 311, an arc-shaped plate 312 fixedly connected to the outer wall of the rubber ring 311, a support block 313 fixedly connected to one end of the arc-shaped plate 312, and a connecting block 314 fixedly connected to the other end of the arc-shaped plate 312. The outer wall of the support block 313 is fixedly connected to the outer side wall of the insulating sleeve 2, and the outer wall of the connecting block 314 is fixedly connected to the inner side wall of the wrapping sleeve 4. The rubber ring 311 has good flexibility and elasticity. When the cable is torsioned by external force, the rubber ring 311 will deform to a certain extent, absorbing part of the torsional force, thereby reducing the torsional stress on the conductor 1. The arc-shaped plate 312 is elastic. At the same time, by utilizing the shape characteristics and elastic characteristics of the arc-shaped plate 312, the resistance to torsional force will be enhanced. When the cable is torsioned, the arc-shaped plate 312 will deform accordingly with the deformation of the rubber ring 311, dispersing the torsional force through its own bending, thereby improving the anti-torsion performance of the cable.

[0023] The first reset device 32 includes a first collar 321, with an inner concave strip 322 fixedly connected to the side wall of the first collar 321. The outer wall of the first collar 321 is fixedly connected to the side wall of the connecting block 314, and the outer wall of the inner concave strip 322 is in contact with the outer wall of the insulating sleeve 2.

[0024] The second reset device 33 includes a second collar 331, with an outwardly protruding strip 332 fixedly connected to the side wall of the second collar 331. The outer wall of the second collar 331 is fixedly connected to the outer wall of the support block 313. The outer wall of the outwardly protruding strip 332 is in contact with the inner side wall of the wrapping sleeve 4. When the cable is subjected to external force compression or stretching, the first reset device 32 and the second reset device 33 will interact with each other. When the cable is compressed, the inner concave strip 322 and the outwardly protruding strip 332 will move closer to each other due to compression. At this time, the outwardly protruding strip 332 and the inner concave strip 322 will undergo elastic deformation, thereby absorbing the compression energy and playing a buffering role. When the external force disappears, the first collar 321 and the second collar 331 will rely on their own elasticity to restore their original shape, driving the inner concave strip 322 and the outwardly protruding strip 332 back to the initial position, so that the cable returns to the unstressed state.

[0025] In use, the conductor 1 is the energized part that transmits current, and the insulating sleeve 2 fixedly connected to its outer wall serves to isolate the current and prevent current leakage from causing safety problems. The protective device 3 is the main device to improve the overall strength of the cable.

[0026] The anti-torsion device 31 in the protective device 3 works in concert with the rubber ring 311, the arc plate 312, the support block 313, and the connecting block 314. The rubber ring 311 has good flexibility and elasticity. When the cable is torsioned by external force, the rubber ring 311 will deform to a certain extent, absorbing part of the torsional force, thereby reducing the torsional stress on the conductor 1 and reducing the risk of damage to the internal circuit due to torsion. The corresponding arc plate 312 is connected to the outer wall of the rubber ring 311. The support block 313 at one end is fixed to the insulating sleeve 2, and the connecting block 314 at the other end is fixed to the wrapping sleeve 4. This structural design enables the anti-torsion device 31 to form a stable connection between the insulating sleeve 2 and the wrapping sleeve 4. The arc plate 312 has elasticity. At the same time, by utilizing the shape characteristics and elastic characteristics of the arc plate 312, the resistance to torsional force will be enhanced. When the cable is torsioned, the arc plate 312 will deform accordingly with the deformation of the rubber ring 311, and disperse the torsional force through its own bending, improving the anti-torsion performance of the cable and providing initial buffer for the cable.

[0027] Both the first reset device 32 and the second reset device 33 are elastic and provide impact resistance. The first ring 321 of the first reset device 32 is fixed to the side wall of the connecting block 314, and the concave strip 322 of its side wall contacts the outer wall of the insulating sleeve 2. The second ring 331 of the second reset device 33 is fixed to the outer wall of the support block 313, and the convex strip 332 of its side wall contacts the inner side wall of the wrapping sleeve 4. The two are nested together and wrapped around the outside of the insulating sleeve 2. When the cable is subjected to external pressure or stretching, the first reset device 32 and the second reset device 33 can be repositioned to reposition themselves ... The second reset devices 33 interact with each other. When the cable is compressed, the concave strip 322 and the convex strip 332 will move closer together due to the compression. At this time, the convex strip 332 and the concave strip 322 will undergo elastic deformation, thereby absorbing the compression energy and playing a buffering role. When the external force disappears, the first ring 321 and the second ring 331 will rely on their own elasticity to restore their original shape, driving the concave strip 322 and the convex strip 332 back to their initial position, so that the cable returns to an unloaded state, effectively avoiding permanent deformation caused by external force.

[0028] The sheath 4 provides the outermost layer of protection for the entire cable. It not only prevents external dust, moisture and other impurities from entering the cable, but also resists minor mechanical damage such as scratches and collisions to a certain extent, further protecting the conductor 1 and other internal structures.

[0029] Overall, the low-voltage cable, through the design of the protection device 3, utilizes the coordinated operation of the anti-torsion device 31, the first reset device 32, and the second reset device 33 to improve the cable's anti-torsion, buffering, and protective performance, thereby extending the cable's service life and ensuring stable power transmission.
