Description

Technical Field

[0001] This application relates to the technical field of cables, and in particular to all-in-one hybrid cables. Background Technology

[0002] In modern electronic devices and systems, multiple cables with different functions often need to work together, such as power transmission and signal transmission. However, cables commonly found on the market are often single-function; for example, ordinary power cables are used only for transmitting electrical energy, and communication cables are used only for transmitting signals. When multiple functional requirements exist simultaneously, multiple different types of cables need to be used. This not only increases the complexity of wiring and occupies more space, but also easily leads to tangling between multiple cables, causing mutual interference and affecting the stability and reliability of the system. Therefore, this application proposes a multi-functional hybrid cable. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this application is to provide an all-in-one hybrid cable that enables the functions of multiple cables to be performed through a single cable.

[0004] The above-mentioned objective of this application is achieved through the following technical solution: an all-in-one hybrid cable, comprising radio frequency (RF) wires for transmitting signals, gas tubes for transmitting gas, power cords for transmitting electricity, and an outer sheath covering the RF wires, gas tubes, and power cords. The outer sheath contains a shielding layer that covers the RF wires, gas tubes, and power cords and shields them from external arc interference. An isolation layer is provided between the outer sheath and the shielding layer to prevent the external environment from directly contacting the RF wires, gas tubes, and power cords.

[0005] By adopting the above technical solution, a single cable can achieve three major functions: radio frequency signal transmission, gas delivery, and power supply, through radio frequency wires, air tubes, and power cables. When a device needs to achieve different energy transmissions, only the corresponding lines need to be connected to the device and the power supply mechanism. For example, when a collaborative robot needs to be connected to the power supply mechanism, simply connect one end of the radio frequency wire in the hybrid cable to the sensor of the collaborative robot and the other end to the control host; connect one end of the air tube to the vacuum suction cup of the collaborative robot and the other end to the cylinder; and finally connect one end of the power cable to the drive system of the collaborative robot and the other end to the power supply system. This allows the hybrid cable to simultaneously provide radio frequency signal transmission, gas delivery, and power supply to the collaborative robot. The integrated power supply and transmission system allows workers to complete the overall energy transmission of the collaborative robot without deploying additional cables. This reduces wiring complexity and cable space requirements, enabling a single cable to perform multiple functions. It meets the multi-functional needs of various fields, reduces the number of cables used, simplifies the system structure, and lowers costs. The shielding layer effectively blocks external arc interference and prevents electromagnetic radiation generated by the cable itself from leaking out, ensuring the purity and stability of signal transmission. The insulation layer allows the cable to adapt to deformation in different environments, prevents direct contact between the external environment and the insulation layer, reduces the corrosion of the insulation layer by moisture, oxygen, and other substances, and extends the cable's service life.

[0006] Furthermore, the outer sheath has an isolation block inside for isolating radio frequency wires, air pipes and power lines. The isolation block has multiple mounting holes at its end that penetrate the isolation block. The radio frequency wires, air pipes and power lines are installed inside the isolation block through the mounting holes. The shielding layer wraps around the isolation block.

[0007] While the above technical solution enables a single cable to perform radio frequency signal transmission, gas delivery, and power supply, in actual use, the RF wires, air pipes, and power cables may become entangled due to external influences (such as impacts, bending, or twisting). This can lead to mutual interference and reduced transmission performance. The isolation block solves this problem. During production, workers simply install the RF wires, air pipes, and power cables into mounting holes, which separates them. This prevents them from becoming entangled and thus avoids mutual interference and reduced transmission performance. Furthermore, the isolation block ensures that if one cable fails, the others will not be affected.

[0008] Furthermore, multiple isolation blocks are provided, and the multiple isolation blocks are arranged sequentially within the shielding layer. Multiple connecting hoses are fixedly provided between any two adjacent isolation blocks. The number of connecting hoses is the same as the number of mounting holes opened on the isolation blocks. All the connecting hoses correspond one-to-one with the mounting holes and cover the mounting holes. The connecting hoses are connected to the mounting holes.

[0009] While the isolation blocks prevent interference between RF wires, air pipes, and power lines, the fact that the isolation blocks are entirely inside the cable reduces its overall flexibility and ease of wiring. This restricts the work of the workers. The problem is solved by using multiple isolation blocks arranged sequentially within the shielding layer, with multiple connecting hoses fixed between any two adjacent isolation blocks. When the cable bends or twists, the connecting hoses between the isolation blocks elastically deform, absorbing the stress and preventing direct stress on the internal RF wires, air pipes, and power lines. The connecting hoses connecting to the mounting holes also provide some space for internal components to adapt to deformation. This allows the cable to adapt more smoothly to complex environments and operational needs during installation and use, reducing fatigue damage caused by repeated bending and twisting, lowering the risk of damage due to improper operation, and effectively improving the overall flexibility and extending the cable's service life.

[0010] Furthermore, the space between the mounting hole wall and the power line is filled with a filler layer.

[0011] While the isolation block prevents interference between the RF wires, air tubes, and power cords, the varying sizes of the power cords can lead to excessive gaps between them and the hole wall after insertion. This prevents the power cords from being securely installed and may cause misalignment during cable production. The filler layer solves this problem. During production, workers simply install the RF wires, air tubes, and power cords into the installation holes and then fill the area around power cords with filler cotton thread (smaller than the hole diameter). This ensures stable installation and prevents misalignment during cable production.

[0012] Furthermore, the shielding layer is a woven shielding structure.

[0013] By adopting the above technical solutions, the braided shielding structure can effectively block external arc interference, while preventing the electromagnetic radiation generated by the cable itself from leaking out, thus ensuring the purity and stability of signal transmission.

[0014] Furthermore, the outer protective layer is made of a silicone-like material.

[0015] By adopting the above technical solutions, the silicone-like material is soft, has good formability, excellent weather resistance, and a certain degree of lubricity, which can improve the safety of cable use and enable the cable to maintain good physical properties and appearance quality under different environmental conditions.

[0016] Furthermore, the trachea is made of polyether-type TPU.

[0017] By adopting the above technical solutions, polyether-type TPU has good flexibility and can easily adapt to complex movements. It is not easily degraded in humid environments, does not dry or condense vertically, and has high biocompatibility and is non-toxic. It is especially suitable for medical and other scenarios with high safety requirements and can be used to protect the internal structure of cables from damage such as external compression.

[0018] Furthermore, the isolation layer is made of non-woven fabric.

[0019] By adopting the above technical solutions, non-woven fabrics have good flexibility, which can adapt to the deformation of cables in different environments, prevent the external environment from directly contacting the insulation layer, reduce the erosion of the insulation layer by moisture, oxygen and other substances, and extend the service life of cables.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. By using a multi-functional hybrid cable, the complexity of wiring is reduced, the space occupied by the cable is also reduced, and the filling layer can prevent the radio frequency wires, air tubes and power lines from getting tangled together, keeping the internal structure of the cable neat and orderly. It achieves the purpose of realizing the functions of multiple cables with a single cable, meets the multi-functional needs of different fields, reduces the number of cables used, simplifies the system structure and reduces costs.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1 The all-in-one hybrid cable includes an RF cable 1 for transmitting signals, an air tube 2 for transmitting gas, a power cord 3 for transmitting electricity, and an outer sheath 4 that wraps the RF cable 1, air tube 2, and power cord 3. Inside the outer sheath 4, there is a shielding layer 5 that wraps the RF cable 1, air tube 2, and power cord 3 and shields against external electric arc interference. Between the outer sheath 4 and the shielding layer 5, there is an isolation layer 6 that prevents the external environment from directly contacting the RF cable 1, air tube 2, and power cord 3.

[0027] The radio frequency cable 1 adopts a coaxial structure, with the inner conductor transmitting signals and the outer conductor working in conjunction with the shielding layer 5 to form a double shielding system, suppressing radiation leakage and external coupling interference. As for the power cable 3, its conductor is made of multi-strand fine copper wires twisted together to improve flexibility to adapt to frequent bending scenarios (such as robot joints). At the same time, through the cooperation of the insulation layer and the shielding layer 5, it blocks the interference of high voltage power to low voltage signal lines.

[0028] By using radio frequency (RF) wire 1, air tube 2, and power cable 3, a single cable can achieve three major functions: RF signal transmission, gas delivery, and power supply. When a device needs to achieve different energy transmissions, only the corresponding lines need to be connected to the device and the power supply mechanism. For example, when a collaborative robot needs to be connected to the power supply mechanism, simply connect one end of RF wire 1 in the hybrid cable to the sensor of the collaborative robot and the other end to the control host; connect one end of air tube 2 to the vacuum suction cup of the collaborative robot and the other end to the cylinder; and finally connect one end of power cable 3 to the drive system of the collaborative robot and the other end to the power supply system. This allows the hybrid cable to simultaneously provide RF signal transmission, gas delivery, and power supply for the collaborative robot, enabling operators to complete the overall energy transmission of the collaborative robot without deploying other cables. This reduces the complexity of wiring, reduces the space occupied by cables, and achieves the goal of realizing multiple functions of a single cable. It meets the multi-functional needs of different fields, reduces the number of cables used, simplifies the system structure, and reduces costs.

[0029] The shielding layer 5 effectively blocks external arc interference and prevents electromagnetic radiation generated by the cable itself from leaking out, ensuring the purity and stability of signal transmission.

[0030] The isolation layer 6 can adapt to the deformation of the cable in different environments, prevent the external environment from directly contacting the insulation layer, reduce the corrosion of the insulation layer by moisture, oxygen and other substances, and extend the service life of the cable.

[0031] Although the arrangement of the RF cable 1, air tube 2, and power cable 3 enables a single cable to perform the three functions of RF signal transmission, gas delivery, and power supply, in actual use, due to external influences (such as impact, bending, or twisting), the RF cable 1, air tube 2, and power cable 3 may become entangled, causing them to interfere with each other and reducing their transmission performance. To solve this technical problem, refer to... Figure 2 In this embodiment, an isolation block 8 is provided inside the outer protective layer 4 to isolate the radio frequency wire 1, the air tube 2 and the power line 3. Multiple mounting holes 80 are provided at the end of the isolation block 8. The radio frequency wire 1, the air tube 2 and the power line 3 are installed inside the isolation block 8 through the mounting holes 80. The shielding layer 5 wraps the isolation block 8.

[0032] With the isolation block 8 in place, during the production process, workers only need to install the RF wire 1, air tube 2, and power line 3 into the mounting hole 80. In this way, the isolation block 8 can separate the RF wire 1, air tube 2, and power line 3. When the RF wire 1, air tube 2, and power line 3 are affected by external factors, the isolation block 8 can block the RF wire 1, air tube 2, and power line 3, preventing them from getting tangled together. This prevents the RF wire 1, air tube 2, and power line 3 from interfering with each other, which would lead to a decrease in the transmission performance of the RF wire 1, air tube 2, and power line 3. Furthermore, by separating the RF wire 1, air tube 2, and power line 3 with the isolation block 8, if one of these lines is damaged, it will not affect the normal operation of the other lines.

[0033] Although the isolation block 8 prevents the radio frequency cable 1, air tube 2, and power cable 3 from interfering with each other, the fact that the isolation block 8 is completely filled inside the cable reduces the overall flexibility of the cable, thus limiting the wiring and cabling work. To solve this technical problem, refer to... Figure 2 In this embodiment, multiple isolation blocks 8 are set, and the multiple isolation blocks 8 are arranged sequentially in the shielding layer 5. Multiple connecting hoses 81 are fixedly arranged between any two adjacent isolation blocks. The number of connecting hoses 81 is the same as the number of mounting holes 80 opened on the partition block. The connecting hoses 81 correspond one-to-one with the multiple mounting holes 80 and cover the mounting holes 80. The connecting hoses 81 are connected to the mounting holes 80.

[0034] Both the isolation block 8 and the connecting hose 81 can be made of flexible insulating material. The connecting hose 81 can be fixedly connected to the isolation block 8 by bonding, hot melting or integral molding.

[0035] When the cable bends or twists, the connecting hose 81 between the insulating blocks 8 can elastically deform to absorb the stress generated by bending or twisting, preventing the stress from acting directly on the internal core and other structures. At the same time, the connecting hose 81 connecting the mounting hole 80 can also provide a certain amount of space for the internal components to adapt to deformation. This allows the cable to adapt more smoothly to complex environments and operational requirements during installation and use, reduces fatigue damage caused by repeated bending and twisting, and lowers the risk of damage caused by improper operation, thereby effectively improving the overall flexibility of the cable and extending its service life.

[0036] Although the isolation block 8 can prevent the radio frequency wire 1, air tube 2 and power cord 3 from interfering with each other, the power cords 3 are of different sizes. This results in some power cords 3 having an excessively large gap between the power cord 3 and the wall of the mounting hole 80 after being inserted into the mounting hole 80. This makes it impossible for the power cord 3 to be stably installed in the mounting hole 80, which may cause the power cord 3 to become misaligned during the entire process of cable production. In order to solve this technical problem, in this embodiment, a filling layer 7 is filled in the gap between the wall of the mounting hole 80 and the power cord 3.

[0037] The filling layer 7 can be made of cotton thread, which has good flexibility and can adapt to bending and stretching deformations of the cable while maintaining the stability of the cable structure. Alternatively, PP mesh tear rope can be used, which has flame-retardant and non-hygroscopic properties and is suitable for cables used in high-temperature environments. Natural fibers (such as jute and cotton yarn) can also be used, which have hygroscopic properties and are suitable for low-humidity environments.

[0038] With the addition of the filling layer 7, during the production process, workers only need to install the RF wire 1, air tube 2, and power cord 3 into the mounting hole 80, and then fill the periphery of the power cord 3, which has a diameter smaller than the mounting hole 80, with cotton thread from the filling layer 7. This ensures that the power cord 3 is stably installed in the mounting hole 80, preventing misalignment of the power cord 3 during the entire cable production process.

[0039] In this embodiment, the shielding layer 5 is a braided shielding structure. The braided shielding structure can effectively block external arc interference and prevent the electromagnetic radiation generated by the cable itself from leaking out, thus ensuring the purity and stability of signal transmission.

[0040] In other embodiments, the shielding layer 5 may also be made of metal foil, such as copper foil or aluminum foil. Copper foil has better conductivity and higher shielding effectiveness (70-100dB), making it suitable for high-frequency interference scenarios, but it is more expensive. Aluminum foil is cheaper and lighter, and its shielding effectiveness can reach 60-90dB, but it has poor flexibility and is easy to break, making it suitable for lightweight scenarios.

[0041] In this embodiment, the outer sheath 4 is made of silicone-like material. Silicone-like material is soft, has good moldability, excellent weather resistance, and certain lubricity, which can improve the safety of cable use and enable the cable to maintain good physical properties and appearance quality under different environmental conditions.

[0042] In this embodiment, the air tube 2 is made of polyether-type TPU. Polyether-type TPU has good flexibility and can easily and freely adapt to complex movements. It is not easily degraded in humid environments, does not dry or condense vertically, and has high biocompatibility and is non-toxic. It is especially suitable for medical and other scenarios with high safety requirements and can be used to protect the internal structure of the cable from damage such as external compression.

[0043] In this embodiment, the insulating layer 6 is a non-woven fabric. Non-woven fabric has good flexibility and can adapt to the deformation of the cable in different environments, prevent the external environment from directly contacting the insulation layer, reduce the erosion of the insulation layer by moisture, oxygen and other substances, and extend the service life of the cable.

[0044] The specific implementation process is as follows: First, install the radio frequency wire 1, air tube 2 and power cord 3 into the mounting hole 80 of the isolation block 8. Then, use a cable cotton filling machine to fill the perimeter of the line with a diameter smaller than the mounting hole 80 with cotton thread. After filling, wrap the shielding layer 5 around the outside of the isolation block 8. Then, wrap the isolation layer 6 around the outside of the shielding layer 5. Then, use an extruder to extrude the outer sheath 4 onto the outside of the isolation layer 6. Finally, install the connecting plugs on both ends of the radio frequency wire 1, air tube 2 and power cord 3.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
