Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire and cable technology, specifically to a flat, anti-torsion traveling cable. Background Technology
[0002] In many fields such as modern industrial production, elevator operation, and automated equipment transmission, flat traveling cables have become key components for power transmission and signal transmission due to their advantages such as small space occupation and easy installation.
[0003] Traditional flat traveling cables are prone to torsion during use due to frequent movement, stretching, and bending. Excessive torsion can cause internal conductors to become entangled or break, leading to power transmission interruptions or signal distortion, affecting the normal operation of equipment, and even causing safety accidents. Furthermore, during prolonged operation, the internal resistance of the cable generates heat. Traditional cables have poor heat dissipation structures and low heat dissipation efficiency. Heat accumulation not only accelerates the aging of the cable insulation layer and reduces the cable's lifespan but also poses safety hazards such as fire. In addition, traditional cables have poor protective performance and cannot guarantee the integrity and stability of the cable when facing friction, compression, and chemical corrosion in complex environments, resulting in frequent cable failures and high maintenance costs. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a flat, anti-twist traveling cable that solves the problems of traditional cables being prone to twisting, having poor heat dissipation, weak protection, leading to frequent faults and high maintenance costs.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a flat, anti-torsion traveling cable, comprising: a cable body, a reinforcing device sleeved on the outer wall of the cable body, an anti-torsion device bonded to the outer wall of the reinforcing device, the reinforcing device including an insulation layer, a reinforcing heat dissipation layer bonded to the outer wall of the insulation layer, and triangular heat dissipation holes formed on the inner wall of the reinforcing heat dissipation layer, the triangular heat dissipation holes being arranged in a circumferential array along the central axis of the reinforcing heat dissipation layer. The circumferential array of triangular heat dissipation holes on the inner wall of the reinforcing heat dissipation layer significantly increases the heat dissipation area, enabling rapid dissipation of heat generated during cable operation, and preventing cable performance degradation or safety hazards caused by heat accumulation.
[0006] Preferably, the inner wall of the insulation layer is in contact with the cable body, and the inner wall of the reinforced heat dissipation layer is in contact with the outer wall of the anti-torsion device.
[0007] Preferably, the outer wall of the reinforced heat dissipation layer is bonded with a sheath. The combination of the reinforced heat dissipation layer, the insulation layer, and the sheath not only provides reliable insulation protection for the cable, but also improves the overall pressure resistance and wear resistance of the cable, enabling it to work stably in complex environments.
[0008] Preferably, the anti-torsion device includes a reinforcing rib, the outer wall of which is in contact with the inner wall of the reinforced heat dissipation layer. The reinforcing rib in the anti-torsion device is tightly fitted with the cable body, which can effectively limit the torsional deformation of the cable.
[0009] Preferably, the anti-torsion device further includes an insulating outer layer, the outer wall of which has an arc-shaped groove, and the inner wall of the arc-shaped groove is arranged in a circumferential array along the central axis of the insulating outer layer. The inner wall of the insulating outer layer is bonded to the outer wall of the sheath. The arc-shaped grooves arranged in a circumferential array on the insulating outer layer can disperse torsional stress through the mutual cooperation between the grooves when the cable is subjected to external force, which greatly improves the cable's anti-torsion ability and extends the cable's service life. Beneficial effects
[0010] This invention provides a torsion-resistant flat traveling cable. It has the following advantages:
[0011] This utility model, through the combination of a reinforcement device and an anti-torsion device, effectively limits the torsional deformation of the cable by ensuring that the reinforcing ribs in the anti-torsion device fit tightly against the cable body. Meanwhile, the arc-shaped grooves arranged in a circular array on the outer insulation layer disperse torsional stress when the cable is subjected to external forces, greatly improving the cable's torsional resistance and extending its service life. The triangular heat dissipation holes arranged in a circular array on the inner wall of the reinforced heat dissipation layer significantly increase the heat dissipation area, quickly dissipating the heat generated during cable operation and preventing performance degradation or safety hazards due to heat accumulation. Furthermore, the combination of the reinforced heat dissipation layer with the insulation layer and sheath not only provides reliable insulation protection for the cable but also improves its overall compressive strength and abrasion resistance, enabling stable operation even in complex environments.

[0015] 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. Example
[0016] Please see Figure 1-2 This utility model provides a technical solution: a torsion-resistant flat traveling cable, comprising:
[0017] The cable body 1 has a reinforcing device 2 fitted on its outer wall and an anti-torsion device 3 bonded to its outer wall. The cable body 1 is protected from bending during use by the cooperation of the reinforcing device 2 and the anti-torsion device 3, which would affect its later use.
[0018] The reinforcement device 2 includes an insulation layer 20, and a reinforcement heat dissipation layer 21 is bonded to the outer wall of the insulation layer 20. The inner wall of the reinforcement heat dissipation layer 21 has triangular heat dissipation holes 22, and the inner wall of the triangular heat dissipation holes 22 is arranged in a circumferential array along the central axis of the reinforcement heat dissipation layer 21. The inner wall of the insulation layer 20 is in contact with the cable body 1, and the inner wall of the reinforcement heat dissipation layer 21 is in contact with the outer wall of the anti-torsion device 3. A sheath 23 is bonded to the outer wall of the reinforcement heat dissipation layer 21. When the cable is subjected to external force and may be twisted, the reinforcing ribs 30 in the anti-torsion device 3 are tightly attached to the cable body 1. With its own rigid structure, it physically restricts the torsional deformation of the cable. At the same time, the arc-shaped grooves 32 arranged in a circumferential array on the outer insulation layer 31 can disperse the torsional stress to the entire outer insulation layer 31 through the interlocking and sliding cooperation between the grooves when external force is applied, thereby effectively resisting the torsional external force, ensuring that the cable maintains a stable shape under complex usage scenarios, and ensuring that power transmission is not interfered with by torsion.
[0019] The anti-torsion device 3 includes a reinforcing rib 30, the outer wall of which contacts the inner wall of the reinforced heat dissipation layer 21. The anti-torsion device 3 also includes an insulating outer layer 31, the outer wall of which has an arc-shaped groove 32. The inner wall of the arc-shaped groove 32 is arranged in a circumferential array along the central axis of the insulating outer layer 31. The inner wall of the insulating outer layer 31 is bonded to the outer wall of the sheath 23. During cable operation, the internal current generates heat. The triangular heat dissipation holes 22 arranged in a circumferential array on the inner wall of the reinforced heat dissipation layer 21 utilize their unique geometry and large surface area... The enlarged inner wall space significantly increases the contact area with air, accelerating heat convection and conduction, allowing the heat generated by the cable to be quickly dissipated into the external environment, preventing heat accumulation from affecting cable performance. In addition, the insulation layer 20 provides reliable electrical insulation protection for the cable body 1, isolating the risk of current leakage. The combination of the reinforced heat dissipation layer 21 and the sheath 23 enhances the cable's pressure resistance and abrasion resistance from a physical perspective, enabling it to resist mechanical damage such as external friction and compression, and comprehensively ensuring the safe and stable operation of the cable under complex working conditions.
[0020] During use, the cable body 1, through the cooperation of the reinforcement device 2 and the anti-torsion device 3, avoids bending during use, which would affect its later use;
[0021] First, when the cable is subjected to external force and may twist, the reinforcing ribs 30 in the anti-twist device 3 are tightly attached to the cable body 1. With its own rigid structure, it physically restricts the torsional deformation of the cable. At the same time, the arc-shaped grooves 32 arranged in a circular array on the outer insulating layer 31 can disperse the torsional stress to the entire outer insulating layer 31 through the interlocking and sliding cooperation between the grooves when external force is applied. This effectively resists the torsional external force, ensures that the cable maintains a stable shape under complex usage scenarios, and ensures that power transmission is not affected by torsion.
[0022] During cable operation, the internal current generates heat. The triangular heat dissipation holes 22 arranged in a circular array on the inner wall of the reinforced heat dissipation layer 21, with their unique geometry and large inner wall space, significantly increase the contact area with air, accelerating heat convection and conduction. This allows the heat generated by the cable to be quickly dissipated into the external environment, preventing heat accumulation from affecting cable performance. In addition, the insulation layer 20 provides reliable electrical insulation protection for the cable body 1, isolating the risk of current leakage. The combination of the reinforced heat dissipation layer 21 and the sheath 23 enhances the cable's pressure resistance and abrasion resistance from a physical perspective, enabling it to resist external friction, compression, and other mechanical damage, and comprehensively ensuring the safe and stable operation of the cable under complex working conditions.
