Abstract
Description
Technical Field
[0001] This invention relates to the field of cable technology, specifically to a highly flexible shielded control cable. Background Technology
[0002] Shielded cables are transmission lines that use a metal mesh braid to wrap the signal lines. Shielding is to ensure the transmission performance of the system in the presence of electromagnetic interference. The anti-interference capability here should include two aspects: the ability to resist external electromagnetic interference and the ability of the system itself to radiate electromagnetic interference.
[0003] The following problems still exist in the actual laying and long-term use of cables:
[0004] Limited resistance to torsion and bending: When cables are subjected to large external forces for bending or torsion, they often cannot automatically return to their original shape and require manual correction, which affects laying efficiency.
[0005] Insufficient conductor protection: When the cable twists, the conductors may be squeezed against each other, increasing the risk of insulation damage and thus affecting the safety and stability of operation;
[0006] Insufficient balance between flexibility and protection: Although some armored cables can avoid excessive twisting, they are less flexible, which is not conducive to construction and laying in narrow or complex spaces.
[0007] Therefore, how to further improve the torsion resistance, bending resistance and compressive strength of cables while ensuring good shielding performance, and taking into account both flexibility and protection, remains a problem that needs to be solved by those skilled in the art. Summary of the Invention
[0008] This invention provides a highly flexible shielded control cable, which can effectively solve the problems mentioned in the background art.
[0009] To achieve the above objectives, the present invention provides the following technical solution: a highly flexible shielded control cable, comprising conductors, wherein a plurality of conductors are provided, an insulation layer is wrapped around the outside of the conductors, and a torsion-resistant bending assembly is provided on the outside of the insulation layer, wherein the torsion-resistant bending assembly includes an inner support tube;
[0010] An inner support tube is provided at the center of the insulation layer. A partition bladder is connected to the outside of the inner support tube by a number of connecting ribs. The insulation layer is divided at equal intervals by the partition bladders. A number of anti-torsion cavities are provided inside the partition bladders. Anti-torsion strips are filled in the middle of the anti-torsion cavities.
[0011] The inner support tube is internally connected to several waist drum springs, and a conical bladder is connected in the middle of each waist drum spring. The conical bladder is filled with an internal flame retardant. One end of each waist drum spring is connected to a threaded head, and the other end of each waist drum spring is connected to a threaded cylinder.
[0012] According to the above technical solution, the anti-torsion strip has a plurality of bending holes at equal intervals on its surface, and the partition bag has a plurality of bending openings at equal intervals on its surface, with the bending holes and bending openings corresponding one-to-one.
[0013] According to the above technical solution, two adjacent waist drum springs are connected by a threaded head and a threaded cylinder, the threaded head is connected to the adjacent threaded cylinder, and both ends of the conical bladder are connected to the adjacent threaded head and the adjacent threaded cylinder by a pull-back rope.
[0014] According to the above technical solution, a number of embedded grooves are provided at equal intervals on the outer side of the partition bladder, and a bending-resistant strip is embedded inside the embedded groove.
[0015] According to the above technical solution, the outer side of the partition bladder is wrapped with a protective sleeve, and the gap between the insulating layer, the partition bladder and the protective sleeve is filled with a silicone sheet.
[0016] According to the above technical solution, multiple silicone sheets are provided, and the silicone sheets are distributed at equal intervals. Copper wires are embedded in the silicone sheets.
[0017] According to the above technical solution, a pressure-resistant protection component is provided on the outside of the protective sleeve, and the pressure-resistant protection component includes a shielding layer;
[0018] The protective sleeve is wrapped with a shielding layer on the outside, and the shielding layer is wrapped with an inner sheath on the outside. Several support rings are evenly spaced on the outside of the inner sheath. Several limiting boxes are welded to the outside of the support rings. A torsion spring is connected between two opposite limiting boxes. Support feet are provided at both ends of the torsion spring. The support feet are embedded in the inside of the adjacent limiting boxes. A force-bearing tube is embedded inside the torsion spring. A force-bearing arc plate is connected to the top of the force-bearing tube.
[0019] A protective cotton is fitted between two adjacent support rings and outside the inner sheath. Several installation holes are equally spaced inside the protective cotton. A steel wire rope is connected between the interiors of adjacent force-bearing tubes in the longitudinal direction and passes through the interior of the installation holes.
[0020] According to the above technical solution, a connecting sleeve is sleeved on the outside of the wire rope, and a powder storage bladder is connected between two adjacent connecting sleeves. The powder storage bladder is filled with an external flame retardant.
[0021] According to the above technical solution, a silicone ring is sleeved on the outside of the support ring and on the outside of the force-bearing arc plate. The silicone ring is located between two adjacent protective cottons, and the protective cottons and the silicone ring are wrapped with an outer protective sleeve.
[0022] According to the above technical solution, S-shaped spring sheets are welded between the bottom two ends of the force-bearing arc sheet and the top of the phase limiting box.
[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0024] 1. Equipped with torsion and bending resistant components, the anti-torsion strips and bending resistant strips are made of elastic rubber. When the cable is twisted and bent, the anti-torsion strips and bending resistant strips deform. After the external force is removed, the cable can return to its original shape under the elastic rebound of the anti-torsion strips and bending resistant strips, which improves the cable's torsion and bending resistance performance and facilitates cable laying. At the same time, the anti-torsion strips and the separators work together to evenly separate each conductor. When the cable is twisted and bent, it avoids the conductors from squeezing each other and causing damage to the insulation layer, protecting the internal conductors of the cable and ensuring the operational stability of the cable.
[0025] When the cable is bent, the bending hole and bending opening can provide bending space for the cable. The anti-torsion strip and the separator enhance the cable's resistance to torsion and bending, while also ensuring the cable's flexibility and facilitating cable laying.
[0026] The conical spring and pull rope are made of elastic rubber. When the cable is bent, the waist drum spring, pull rope and conical spring bend and stretch. After the external force is removed, they quickly rebound, which improves the toughness of the cable and makes the cable more resistant to bending. The conical spring is filled with an internal flame retardant, which is aluminum hydroxide powder. In the event of a fire, it reduces the combustion reaction rate. Two adjacent waist drum springs are connected by a threaded head and a threaded cylinder, which makes it easy to connect and disassemble the waist drum springs. After the fire, the waist drum springs can be easily recycled.
[0027] The silicone sheets are evenly spaced, allowing the heat generated by the conductor to be quickly conducted to the inside of the silicone sheets. Copper wires are embedded in the silicone sheets between them to facilitate the dissipation of heat generated by the conductor, preventing heat accumulation that could increase conductor resistance and resulting in better power transmission capacity of the cable.
[0028] 2. Equipped with a pressure-resistant protection component, the limit box limits the support foot. When the force-bearing arc plate is subjected to external force, the torsion spring rotates and the S-shaped spring bends, converting the external force into elastic potential energy. After the external force is removed, the torsion spring and the S-shaped spring return to their original shape, giving the cable stable pressure resistance. Under the action of force transmission, the support ring provides rigid support for the external force, enhancing the cable's pressure resistance. At the same time, the silicone ring absorbs the external force and elastic potential energy. The torsion spring, S-shaped spring, and silicone ring work together to buffer the external force, further enhancing the cable's pressure resistance. The protective cotton and support ring are arranged in sequence. When the cable bends, the support ring will not hinder the cable bending, improving the cable's pressure resistance while also ensuring the cable's flexibility.
[0029] The steel wire rope is fitted with a connecting sleeve on the outside, and a powder storage bladder is connected between two adjacent connecting sleeves. The powder storage bladder is filled with an external flame retardant, which is also aluminum hydroxide powder. The internal and external flame retardants work together to further improve the flame retardancy of the cable. In addition, the steel wire rope can enhance the tensile strength of the cable, ensure the flexibility of the cable, and effectively distribute the longitudinal tension on the cable, reducing the damage to the cable structure caused by external tension.
[0030] In summary, the anti-torsion strip, bending strip, waist drum spring, conical bladder, and powder storage bladder in both components are all made of elastic materials. When the cable is bent or twisted, the components of the two components are evenly distributed on the outer and inner sides of the cable. Compared with the existing technology, the two components work together to fully improve the overall bending and torsion resistance of the cable. During cable laying, this ensures smooth laying and improves the laying efficiency of the cable. Attached Figure Description

[0047] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0048] Example: Figure 1-11 As shown, the present invention provides a highly flexible shielded control cable technical solution, including a conductor 1, which is provided in a plurality of parts. The conductor 1 is wrapped with an insulation layer 2. A torsion-resistant bending assembly 3 is provided on the outside of the insulation layer 2. The torsion-resistant bending assembly 3 includes an inner support tube 301, a connecting rib 302, a partition bladder 303, an anti-torsion cavity 304, an anti-torsion strip 305, a bending hole 306, a bending opening 307, an inner groove 308, a bending strip 309, a protective sleeve 310, a silicone sheet 311, a copper wire 312, a waist drum spring 313, a threaded head 314, a pull rope 315, a threaded cylinder 316, a conical bladder 317, and an inner flame retardant 318.
[0049] An inner support tube 301 is provided in the center of the insulation layer 2. The outer side of the inner support tube 301 is connected to a partition 303 by several connecting ribs 302. The insulation layer 2 is divided at equal intervals by the partition 303. Several anti-torsion cavities 304 are provided inside the partition 303. Anti-torsion strips 305 are filled in the middle of the anti-torsion cavities 304. Several embedded grooves 308 are provided at equal intervals on the outer side of the partition 303. Bending strips 309 are embedded in the embedded grooves 308. The anti-torsion strips 305 and bending strips 309 are made of elastic rubber material. They can produce large deformation after being subjected to force and can return to their original shape after the external force is removed.
[0050] The inner support tube 301, connecting rib 302, partition bladder 303 and protective sleeve 310 are made of halogen-free flame-retardant silicone rubber, which has good flame-retardant properties.
[0051] The surface of the anti-torsion strip 305 is provided with several bending holes 306 at equal intervals, and the surface of the separator 303 is provided with several bending openings 307 at equal intervals. The bending holes 306 and bending openings 307 are in one-to-one correspondence. When the cable is bent, the bending holes 306 and bending openings 307 can provide bending space for the cable to ensure the flexibility of the cable.
[0052] The inner support tube 301 is internally connected to several waist drum springs 313, and a conical bladder 317 is connected in the middle of the waist drum springs 313. The conical bladder 317 is filled with an internal flame retardant 318. The conical bladder 317 is made of elastic rubber and has good elasticity. When the cable is bent, the conical bladder 317 bends and stretches. When the external force is removed, the conical bladder 317 quickly rebounds, which improves the toughness of the cable and makes the cable have good bending resistance. The internal flame retardant 318 is aluminum hydroxide powder. When aluminum hydroxide powder is heated and decomposed, it absorbs a large amount of heat, reduces the surface temperature of the material to below the ignition point of the combustible material, inhibits the combustion chain reaction, and the water vapor produced by the thermal decomposition dilutes the concentration of combustible gases and oxygen produced by combustion, further reducing the combustion reaction rate.
[0053] One end of the waist drum spring 313 is connected to a threaded head 314, and the other end of the waist drum spring 313 is connected to a threaded cylinder 316. Two adjacent waist drum springs 313 are connected through the threaded head 314 and the threaded cylinder 316. The threaded head 314 is connected to the adjacent threaded cylinder 316. Both ends of the conical bladder 317 are connected to the adjacent threaded head 314 and the adjacent threaded cylinder 316 through the pull-back rope 315. Rotating the threaded head 314 can connect and separate the threaded head 314 and the threaded cylinder 316, which facilitates the connection and disassembly of the waist drum spring 313.
[0054] The outer side of the separator 303 is wrapped with a protective sleeve 310. The gap between the insulation layer 2, the separator 303 and the protective sleeve 310 is filled with a silicone sheet 311. The silicone sheet 311 has good thermal conductivity. The silicone sheet 311 is in contact with the insulation layer 2 on the outside of the conductor 1. The heat generated by the conductor 1 during operation can be quickly conducted to the inside of the silicone sheet 311, which facilitates the heat generated by the conductor 1 during operation to be guided away. Multiple silicone sheets 311 are provided and are evenly distributed. Copper wires 312 are embedded in the inside of the silicone sheets 311. The copper wires 312 have a high thermal conductivity, which can further enhance the heat dissipation capacity of the cable.
[0055] The protective sleeve 310 is provided with a pressure-resistant protection component 4 on the outside. The pressure-resistant protection component 4 includes a shielding layer 401, an inner sheath 402, a support ring 403, a limit box 404, a torsion spring 405, a support foot 406, a force-bearing tube 407, a force-bearing arc plate 408, an S-shaped spring plate 409, protective cotton 410, a mounting hole 411, a steel wire rope 412, a connecting sleeve 413, a powder storage bladder 414, a silicone ring 415, an outer sheath 416, and an outer flame retardant 417.
[0056] The inner sheath 402 and the outer sheath 416 are also made of halogen-free flame-retardant silicone rubber. A shielding layer 401 is wrapped around the outside of the protective sleeve 310, and the inner sheath 402 is wrapped around the outside of the shielding layer 401. Several support rings 403 are evenly spaced around the outside of the inner sheath 402. Several limiting boxes 404 are welded to the outside of the support rings 403. A torsion spring 405 is connected between two opposing limiting boxes 404. Support feet 406 are provided at both ends of the torsion spring 405. 406 is embedded inside the adjacent limiting box 404. The torsion spring 405 is embedded inside the force tube 407. The top of the force tube 407 is connected to the force arc plate 408. The limiting box 404 limits the support foot 406. When the force arc plate 408 is subjected to external force, the torsion spring 405 rotates under the action of force transmission, converting the external force into elastic potential energy, avoiding the external force from acting directly on the conductor 1. After the external force is removed, it can return to its original shape, so that the cable has stable compressive strength.
[0057] S-shaped spring pieces 409 are welded between the bottom ends of the force-bearing arc plate 408 and the top of the phase limiting box 404. When the force-bearing arc plate 408 is subjected to external force, the S-shaped spring pieces 409 bend under the force, converting the external force into elastic potential energy. Finally, under the action of force transmission, it is transmitted to the support ring 403. When the cable is subjected to external force, most of the external force is transferred to the support ring 403. The support ring 403 provides rigid support for the external force, enhancing the cable's compressive strength. The support ring 403 is located outside the force-bearing arc plate. A silicone ring 415 is sleeved on the outside of 408. The silicone ring 415 is located between two adjacent protective cotton 410s. The protective cotton 410 and the silicone ring 415 are wrapped with an outer sheath 416. The silicone ring 415 can absorb external force and elastic potential energy. Part of the external force acts on the support ring 403, and part of the external force is absorbed by the silicone ring 415. The torsion spring 405, the S-shaped spring 409 and the silicone ring 415 work together to buffer the external force and further enhance the cable's compressive strength.
[0058] A protective cotton 410 is fitted between two adjacent support rings 403 and outside the inner sheath 402. Several installation channels 411 are opened at equal intervals inside the protective cotton 410. A steel wire rope 412 is connected between adjacent force-bearing tubes 407 in the longitudinal direction. The steel wire rope 412 passes through the installation channel 411.
[0059] A connecting sleeve 413 is sleeved on the outside of the wire rope 412. A powder storage bladder 414 is connected between two adjacent connecting sleeves 413. The powder storage bladder 414 is filled with an external flame retardant 417, which is also aluminum hydroxide powder. The internal flame retardant 318 and the external flame retardant 417 work together to further improve the flame retardancy of the cable. The powder storage bladder 414 is made of elastic rubber and has good elasticity. When the cable is bent, the powder storage bladder 414 also bends. When the external force is removed, the powder storage bladder 414 quickly rebounds, improving the bending resistance of the cable.
[0060] The working principle and usage process of this invention: The anti-torsion strip 305 and the bending strip 309 are made of elastic rubber and have good elasticity. The anti-torsion strip 305 and the bending strip 309 are evenly distributed inside the cable. When the cable is twisted and bent, the anti-torsion strip 305 and the bending strip 309 deform. After the external force is removed, the cable can return to its original shape under the elastic rebound of the anti-torsion strip 305 and the bending strip 309, which improves the cable's torsion resistance and bending resistance, and facilitates the laying of the cable. At the same time, the anti-torsion strip 305 and the separator 303 work together to evenly separate each conductor 1. When the cable is twisted and bent, it avoids the conductors 1 from squeezing each other and causing damage to the insulation layer 2, which further improves the cable's torsion resistance and bending resistance, and ensures the operational stability of the cable.
[0061] The anti-torsion strip 305 has several bending holes 306 evenly spaced on its surface, and the separator 303 has several bending openings 307 evenly spaced on its surface. The bending holes 306 and bending openings 307 are in one-to-one correspondence. When the cable is bent, the bending holes 306 and bending openings 307 can provide bending space for the cable. The anti-torsion strip 305 and separator 303 enhance the cable's resistance to torsion and bending while also ensuring the cable's flexibility and facilitating cable laying.
[0062] The conical bladder 317 and pull cord 315 are made of elastic rubber, possessing excellent elasticity. When the cable bends, the drum spring 313, pull cord 315, and conical bladder 317 bend and stretch. After the external force is removed, the pull cord 315, drum spring 313, and conical bladder 317 quickly rebound, improving the cable's toughness and enhancing its bending resistance. Furthermore, the conical bladder 317 is filled with an internal flame retardant 318, which is aluminum hydroxide powder. In the event of a fire, the aluminum hydroxide powder decomposes upon heating, absorbing a large amount of... The heat reduces the surface temperature of the material to below the ignition point of the combustible material, inhibiting the combustion chain reaction. The water vapor produced by the thermal decomposition dilutes the concentration of combustible gases and oxygen produced by combustion, further reducing the combustion reaction rate. Two adjacent waist drum springs 313 are connected by a threaded head 314 and a threaded cylinder 316. Rotating the threaded head 314 can connect and separate the threaded head 314 and the threaded cylinder 316, making it convenient to connect and disassemble the waist drum springs 313. After the fire, it is convenient to recycle the waist drum springs 313.
[0063] A powder storage bladder 414 is connected between two adjacent connecting sleeves 413. The powder storage bladder 414 is filled with an external flame retardant 417, which is also aluminum hydroxide powder. The internal flame retardant 318 and the external flame retardant 417 work together to further improve the flame retardant capability of the cable.
[0064] The gaps between the insulation layer 2, the separator 303, and the protective sleeve 310 are filled with silicone sheets 311. The silicone sheets 311 are evenly distributed, and the heat generated by the conductor 1 during operation can be quickly conducted to the inside of the silicone sheets 311, which facilitates the heat dissipation of the conductor 1 and enhances the heat dissipation capacity of the cable. Copper wires 312 are embedded in the silicone sheets 311. The copper wires 312 have a high thermal conductivity, which further enhances the heat dissipation capacity of the cable and avoids heat accumulation that would increase the resistance of the conductor 1, resulting in better power transmission capacity of the cable.
[0065] The limiting box 404 limits the support foot 406. When the force-bearing arc plate 408 is subjected to external force, the torsion spring 405 rotates under the action of force transmission, and the S-shaped spring plate 409 bends under the force, converting the external force into elastic potential energy. After the external force is removed, the torsion spring 405 and the S-shaped spring plate 409 return to their original shape, giving the cable stable compressive strength. Finally, under the action of force transmission, the force is transmitted to the support ring 403. When the cable is subjected to external force, the support ring 403 provides rigid support for the external force, enhancing the cable's compressive strength. At the same time, the silicone ring 415 can... External force and elastic potential energy are absorbed. Part of the external force acts on the support ring 403, and part of the external force is absorbed by the silicone ring 415. The torsion spring 405, S-shaped spring 409 and silicone ring 415 work together to buffer the external force, further enhancing the cable's compressive strength. The protective cotton 410 has good flexibility and elasticity and can absorb part of the force. The protective cotton 410 and the support ring 403 are arranged in sequence and cooperate with each other. When the cable is bent, the support ring 403 will not hinder the cable bending, improving the cable's compressive strength while also ensuring the cable's flexibility.
[0066] A connecting sleeve 413 is sleeved on the outside of the wire rope 412. A powder storage bladder 414 is connected between two adjacent connecting sleeves 413. The powder storage bladder 414 is made of elastic rubber. When the cable is bent, the powder storage bladder 414 also bends. When the external force is removed, the powder storage bladder 414 quickly rebounds, which further improves the bending resistance of the cable. In conjunction with the anti-torsion strip 305, bending strip 309, waist drum spring 313, pull rope 315 and conical bladder 317, the overall bending resistance of the cable is better. Moreover, the wire rope 412 can enhance the tensile strength of the cable, effectively share the longitudinal tension on the cable, and reduce the damage to the cable structure caused by external tension.
[0067] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
