Description

Technical Field

[0001] This utility model relates to the field of data cable technology, and in particular to a flexible data cable with high anti-sway performance. Background Technology

[0002] In fields such as consumer electronics, industrial control, and medical devices, flexible data cables are key components for signal and power transmission. Their operating environment often involves frequent bending, swaying, and vibration. Existing flexible data cables mostly adopt a simple multi-layered wrapping structure, which can meet basic transmission requirements. However, under long-term, high-frequency swaying conditions, and given that their function is to connect mobile devices and computers to achieve data transmission or communication purposes—in simpler terms, they are communication tools that connect computers and mobile devices to transfer video, ringtones, pictures, and other files—data cables have become an indispensable part of our lives with the rapid development of the electronics industry.

[0003] Existing data cables are often left unattended and carelessly placed, which can easily lead to breakage, cracking of the wires and connectors, slow charging speeds, and rust at the ends over time, resulting in a shorter lifespan. Furthermore, rusty data cables plugged into devices can impede heat dissipation, causing overheating and potentially burning out the connectors, leading to fires or other safety hazards. Additionally, inferior data cables, if overloaded due to breakage or other reasons, coupled with poor sheathing and flame-retardant insulation, can also cause short circuits.

[0004] Therefore, there is an urgent need to provide a flexible data cable with high anti-sway performance to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a flexible data cable with high anti-sway performance.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a flexible data cable with high anti-sway performance is provided, including a data cable body, a charging interface is fixedly connected to one side of the data cable body, and a USB interface is fixedly connected to the other side of the data cable body. An anti-sway component is installed on one side of the USB interface, which can improve the anti-sway capability of the data cable body during use. The data cable body is equipped with a protective component, which can provide multiple protection functions for the data cable body.

[0007] The present invention is further configured such that: the anti-sway component includes a connecting frame disposed on the outside of the data cable body, and mounting frames are fixedly connected to both sides of the connecting frame; the upper and lower ends of the inner sides of the two mounting frames are provided with sliding grooves; guide rods are fixedly connected inside the sliding grooves; linkage blocks are slidably connected to the outer surfaces of the multiple guide rods; two springs are slidably connected to the outer walls of the multiple guide rods; and a bearing is fixedly connected between the inner sides of every two linkage blocks.

[0008] With the above technical solution, when the data cable body is subjected to external force and sways and vibrates, the force will be transmitted to the connecting frame and the mounting frame. The external force causes the linkage block to slide along the guide rod in the slide groove. Then, during the sliding process, the springs on both sides are squeezed and stretched to generate a reverse elastic force, which offsets part of the swaying force. Subsequently, the data cable body passes through the inner ring of the bearing. When the data cable twists, the bearing allows the data cable to rotate relative to the mounting frame, reducing the direct effect of the torsional force on the data cable body.

[0009] The present invention is further configured such that: each pair of springs is disposed at the front and rear ends of the corresponding linkage block, and all of the springs are in a relaxed state.

[0010] Through the above technical solution, the spring in the relaxed state can generate a reverse elastic force through compression deformation when the linkage block slides in any direction, achieving a bidirectional symmetrical buffering effect and avoiding the buffering bias problem caused by uneven initial preload.

[0011] The present invention is further configured such that: each of the multiple linkage blocks is provided with a guide hole, and each of the multiple guide rods is matched with the corresponding guide hole.

[0012] Through the above technical solution, the matching of the guide hole and the guide rod can strictly constrain the movement trajectory of the linkage block, so that it can only slide along the axial direction of the guide rod, avoiding the linkage block from shifting, tilting or jamming when subjected to force, ensuring the deformation direction of the spring is stable, and the buffer force always acts in the preset direction.

[0013] The present invention is further configured such that: the protective component includes a sheath layer disposed on the outer surface of the data cable body, a tensile layer disposed inside the sheath layer, a shielding layer disposed inside the tensile layer, an insulating layer disposed inside the shielding layer, and a conductor layer disposed inside the insulating layer.

[0014] With the above technical solution, when the data cable is working, the innermost conductor layer transmits electrical signals, the insulation layer isolates the conductor layer from the outside world to prevent leakage, the shielding layer shields external electromagnetic interference to ensure signal stability, the tensile layer enhances the overall tensile strength, and the outermost sheath layer resists external wear and compression. The multiple layers work together to protect the data cable for safe operation.

[0015] The present invention is further configured such that: the tensile layer surrounds the outside of the shielding layer, and the inner diameter of the tensile layer is adapted to the outer diameter of the shielding layer.

[0016] The above technical solution can tightly wrap the shielding layer, avoid interlayer loosening and displacement, and ensure structural stability; and when under stress, the tensile layer can evenly transmit the tensile force, maximize the tensile resistance, and prevent excessive local stress from damaging the shielding layer and internal structure.

[0017] The present invention is further configured such that the sheath layer, tensile layer, shielding layer, insulating layer and conductor layer are arranged coaxially from the outside to the inside.

[0018] Through the above technical solutions, the coaxial design ensures that the central axes of each layer are consistent, avoiding uneven local stress caused by misalignment, reducing interlayer friction and compression, improving the overall structural stability, and the uniform interlayer distribution can avoid excessive local wear or fatigue, allowing the material properties of each layer to be fully utilized, thereby extending the overall service life of the data cable.

[0019] The beneficial effects of this utility model are as follows: 1. By setting an anti-sway component, this utility model enables the data cable to withstand more swings and bends, reducing the breakage of internal wires and damage to the outer sheath caused by swinging. At the same time, it can also effectively protect the connection between the connector and the wire, avoiding poor contact or open circuit due to frequent swinging, thus significantly extending the service life of the data cable. 2. By setting up protective components, this utility model can protect the connection between the connecting cable and the connector, enhance the rigidity of the part, enable it to withstand more swinging and bending, and improve the anti-sway performance of the data cable.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0023] Please see Figure 1 - Figure 5 A flexible data cable with high anti-sway performance includes a data cable body 1. A charging interface 2 is fixedly connected to one side of the data cable body 1, and a USB interface 3 is fixedly connected to the other side of the data cable body 1. An anti-sway component 4 is installed on one side of the USB interface 3. The anti-sway component 4 includes a connecting frame 401 disposed on the outside of the data cable body 1. Mounting frames 402 are fixedly connected to both sides of the connecting frame 401. Sliding grooves 403 are opened at the upper and lower ends of the inner sides of the two mounting frames 402. Guide rods 404 are fixedly connected inside the sliding grooves 403. Linkage blocks 406 are slidably connected to the outer surfaces of the guide rods 404. Two springs 405 are slidably connected to the outer walls of the guide rods 404. A bearing 407 is fixedly connected between the inner sides of every two linkage blocks 406. When the data cable body 1 is subjected to external force and sways and vibrates, the force is transmitted to the connecting frame 401 and the mounting frame 402. The external force causes the linkage blocks 406 to slide along the guide rods 404 in the sliding grooves 403. During the sliding process, the springs 406 on both sides are squeezed and stretched. 5. A reverse elastic force is generated to offset part of the swaying force. Then, the data cable body 1 passes through the inner ring of the bearing 407. When the data cable twists, the bearing 407 allows the data cable to rotate relative to the mounting frame 402, reducing the direct effect of the torsional force on the data cable body 1. Every two springs 405 are set at the front and rear ends of the corresponding linkage block 406, and multiple springs 405 are in a relaxed state. When the linkage block 406 slides in any direction, the relaxed springs 405 can generate a reverse elastic force through compression deformation, achieving a bidirectional symmetrical buffering effect and avoiding buffer bias caused by uneven initial preload. Multiple linkage blocks 406 are provided with guide holes, and multiple guide rods 404 are matched with the corresponding guide holes. The matching of the guide holes and guide rods 404 can strictly constrain the movement trajectory of the linkage block 406, so that it can only slide along the axial direction of the guide rod 404, preventing the linkage block 406 from shifting, tilting, or jamming when subjected to force, ensuring that the deformation direction of the spring 405 is stable, and the buffering force always acts in the preset direction. like Figure 4 and Figure 5 As shown, the anti-sway component 4 enhances the anti-sway capability of the data cable body 1 during use. The data cable body 1 is internally equipped with a protective component 5, which provides multiple protection functions for the data cable body 1. The protective component 5 includes a sheath layer 501 on the outer surface of the data cable body 1, a tensile layer 502 inside the sheath layer 501, a shielding layer 503 inside the tensile layer 502, an insulating layer 504 inside the shielding layer 503, and a conductor layer 505 inside the insulating layer 504. When the data cable is working, the innermost conductor layer 505 transmits electrical signals, the insulating layer 504 isolates the conductor layer 505 from the outside world to prevent leakage, the shielding layer 503 shields against external electromagnetic interference to ensure signal stability, the tensile layer 502 enhances the overall tensile strength, and the outermost sheath layer 501 resists external wear and pressure. This multi-layered synergistic protection provides multiple layers of protection for the data cable body 1. For safe operation of the data cable, the tensile layer 502 surrounds the outside of the shielding layer 503, and the inner diameter of the tensile layer 502 matches the outer diameter of the shielding layer 503. It can tightly wrap the shielding layer 503, preventing interlayer loosening and displacement, and ensuring structural stability. When under stress, the tensile layer 502 can evenly transmit tensile force, maximizing its tensile resistance and preventing excessive local stress from damaging the shielding layer 503 and internal structure. The sheath layer 501, tensile layer 502, shielding layer 503, insulation layer 504, and conductor layer 505 are arranged coaxially from the outside to the inside. The coaxial design ensures that the central axis of each layer is consistent, avoiding uneven local stress caused by misalignment, reducing interlayer friction and compression, improving the overall structural stability, and the uniform interlayer distribution can avoid excessive local wear or fatigue, allowing the performance of each layer material to be fully utilized, thereby extending the overall service life of the data cable.

[0024] When the data cable body 1 is subjected to external force and sways and vibrates, the force is transmitted to the connecting frame 401 and the mounting frame 402. The external force causes the linkage block 406 to slide along the guide rod 404 in the slide groove 403. During the sliding process, the springs 405 on both sides are squeezed and stretched, and the springs 405 generate a reverse elastic force to offset part of the swaying force. Then, the data cable body 1 passes through the inner ring of the bearing 407. When the data cable is twisted, the bearing 407 allows the data cable to rotate relative to the mounting frame 402, reducing the direct effect of the torsional force on the data cable body 1.
