[0027] The specific implementation methods of the present application will be described in further detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 2 As shown, this embodiment provides a network cable 100 with a dehumidification function, including an outer sheath 10 , a central axis 20 , a plurality of brackets 30 , and a sliding assembly 40 .

[0029] An accommodating cavity 101 is provided in the outer sheath 10, and the central axis 20 is rotatably provided in the accommodating cavity 101, and the central axis 20 is coaxially arranged with the outer sheath 10. A plurality of brackets 30 are arranged at equal intervals around the outer circumference of the central axis 20, and a movable cavity 33 is formed between any two adjacent brackets 30. The extension direction of the bracket 30 is parallel to the radial direction of the central axis 20, and one end of the bracket 30 is connected to the inner wall of the outer sheath 10. The number of sliding assemblies 40 is set to be multiple, and a sliding assembly 40 is provided in each movable cavity 33. The sliding assembly 40 includes a sliding frame 41, a wire core 42 and an elastic structure 43. The sliding frame 41 is slidably provided in the movable cavity 33, and a wire cavity 413 is provided in the sliding frame 41, and the wire core 42 is provided in the wire cavity 413. The elastic structure 43 is sandwiched between the sliding frame 41 and the outer sheath 10 and is connected to the outer sheath 10. An air passage 430 is defined in the elastic structure 43. A micropore 412 is defined at one end of the sliding frame 41, proximal to the elastic structure 43. This micropore 412 connects the air passage 430 to the active chamber 33. When the central shaft 20 rotates, the central shaft 20 presses against the sliding frame 41, allowing it to move radially along the central shaft 20. This elastic deformation of the elastic structure 43 causes the air passage 430 to open or close.

[0030] Thus, in the dehumidifying mesh cable 100 of the present application, the rotation of the central shaft 20 drives the sliding frame 41 to slide radially along the central shaft 20 within the active cavity 33, allowing the outer diameter of the inner sheath formed by the multiple sliding assemblies 40 to be adjusted to suit different usage requirements. Furthermore, as the sliding frame 41 slides radially along the central shaft 20, it can resist the elastic structure 43, causing it to elastically deform, thereby opening or closing the air passage 430. When the mesh cable needs to be dehumidified, the air passage 430 is opened by rotating the central shaft 20, and hot air is injected into the air passage 430 from the outside, thereby dehumidifying the internal space of the mesh cable and ensuring the normal operation of the mesh cable. After dehumidification is completed, the central shaft 20 is rotated again to close the air passage 430, thereby ensuring the sealing performance of the mesh cable and preventing moisture from entering the sliding frame 41 and affecting the normal operation of the core 42.

[0031] Please combine again Figures 1 to 2 In one embodiment, the central shaft 20 is cylindrical and extends parallel to the direction of extension of the network cable. The outer circumference of the central shaft 20 defines multiple sets of receiving grooves 21, corresponding to the plurality of sliding assemblies 40. Along the radial direction of the central shaft 20, each sliding frame 41 has a protruding abutment 411 proximate the end of the central shaft 20. The abutment 411 is located approximately midway between the ends of the sliding frame 41 proximate the central shaft 20.

[0032] Each group of receiving slots 21 includes multiple receiving slots 21 for receiving the abutting portions 411. The receiving slots 21 of each group are spaced apart along the rotational direction of the central shaft 20. The central shaft 20 is made of a material such as rubber to ensure that it can bend with the network cable. The central shaft 20 also has a certain structural strength to ensure that the walls of the receiving slots 21 of the central shaft 20 can abut against the abutting portions 411, exerting force on the abutting portions 411 to push the sliding frame 41 to move.

[0033] In this embodiment, there are four brackets 30, which are spaced apart in sequence along the rotation direction of the central axis 20, and the angle between any two adjacent brackets 30 is 90°. There are four abutting portions 411, and the angle between any two adjacent abutting portions 411 is also 90°.

[0034] It is understandable that in other embodiments, the number of sliding components 40 may also be set to other numbers, and the specific number may be selected according to actual design requirements.

[0035] Along the radial direction of the central shaft 20, the receiving groove 21 is formed by being recessed inward from the outer circumference of the central shaft 20. The receiving groove 21 is used to accommodate the abutting portion 411, and the abutting portion 411 can abut against the bottom wall of the receiving groove 21, thereby clamping the sliding frame 41 between the elastic structure 43 and the central shaft 20 to achieve radial positioning of the sliding frame 41. Along the rotation direction of the central shaft 20, the individual receiving grooves 21 in the same group are spaced apart, and the groove depth of each receiving groove 21 increases linearly. The groove depths of each receiving groove 21 are different, so that when the abutting portion 411 is located in different receiving grooves 21, the distance between the sliding frame 41 and the central shaft 20 along the radial direction of the central shaft 20 is different, thereby allowing the elastic structure 43 abutted by the sliding frame 41 to undergo different degrees of elastic deformation.

[0036] In this embodiment, the cross-sectional shape of the abutting portion 411 is substantially semicircular, and the shape of the receiving groove 21 matches the shape of the abutting portion 411. This ensures that when the abutting portion 411 is located in the receiving groove 21, the abutting portion 411 stably limits the position of the sliding frame 41, thereby preventing the sliding frame 41 from shaking. Furthermore, the cross-sectional shape of the abutting portion 411 is semicircular, and the shape of the receiving groove 21 matches the shape of the abutting portion 411. The curved surface guides the abutting portion 411 in and out of the receiving groove 21, thereby ensuring that the abutting portion 411 can be easily removed from the receiving groove 21.

[0037] The cross-sectional shape of the sliding frame 41 is roughly fan-shaped. Along the radial direction of the central shaft 20, the shape of the end face of the sliding frame 41 close to the central shaft 20 is adapted to the outer peripheral surface of the central shaft 20 to ensure that when the central shaft 20 rotates until the supporting portion 411 abuts against the bottom wall of different accommodating grooves 21 and the sliding frame 41 slides, the sliding frame 41 can slide along the radial direction of the central shaft 20.

[0038] Along the radial direction of the central axis 20 , the shape of the end surface of the sliding frame 41 away from the central axis 20 is adapted to the shape of the inner circumferential surface of the outer protective layer 10 , and multiple microholes 412 are evenly spaced and opened on the end surface of the sliding frame 41 away from the central axis 20 .

[0039] The core 42 includes two conductors 421 and an insulating layer 422. The conductors 421 are made of a metal material such as copper or aluminum, and the insulating layer 422 is made of an insulating material such as polyethylene. Along the radial direction of the central axis 20, the opposing sides of the core 42 respectively abut against the inner walls of the sliding frame 41 on opposite sides, thereby limiting the radial position of the core 42 relative to the central axis 20. Furthermore, the sliding frame 41 is filled with a filler, such as a filling rope. Along the rotational direction of the central axis 20, the filler fills the space between the core 42 and the inner walls of the sliding frame 41 on opposite sides, thereby limiting the position of the core 42 relative to the rotational direction of the central axis 20 and ensuring that the core 42 does not wobble within the sliding frame 41.

[0040] Please combine again Figures 1 to 2 In one embodiment, the elastic structure 43 includes a main body 431 and a plurality of first elastic members 432. The main body 431 is generally arc-shaped and is made of an insulating material with a certain degree of elasticity, such as rubber, to allow it to bend to a certain extent with the network cable. Furthermore, the insulating material of the main body 431 provides leakage protection when in contact with the metal sliding frame 41.

[0041] Along the rotational direction of the central axis 20, the ends of the main member 431 respectively abut against two adjacent brackets 30. Because the main member 431 is made of an elastic material, the ends of the main member 431 and the brackets 30 are in close contact, forming a sealed structure. This prevents moisture accumulated on the outer sheath 10 from flowing along the brackets 30 through the gap between the main member 431 and the brackets 30 into the active cavity 33, thereby improving the waterproofness of the wire core 42. Along the radial direction of the central axis 20, one side of the main member 431 is in contact with and connected to the inner wall of the outer sheath 10, while the other side of the main member 431 is defined by a plurality of compression grooves 4310.

[0042] Multiple compression grooves 4310 are arranged corresponding to multiple first elastic members 432, and a first elastic member 432 is installed in each compression groove 4310. The first elastic member 432 can be an elastic element such as a compression spring. One end of the first elastic member 432 is elastically connected to the main member 431, and the other end is elastically connected to the sliding frame 41, so that the first elastic member 432 can apply an elastic force to the sliding frame 41. Because the main member 431 is made of an elastic material, when the main member 431 applies a force to the first elastic member 432 and is subjected to a reaction force, the main member 431 itself can undergo a certain degree of elastic deformation to offset the reaction force, thereby preventing the main member 431 from squeezing the outer sheath 10 and causing localized bulging. At the same time, the elastic main member 431 and the first elastic member 432 can provide radial buffering for the network cable. When the network cable is squeezed by external forces, the elastic deformation of the main member 431 and the first elastic member 432 can offset the external forces, thereby improving the network cable's compressive strength.

[0043] The plurality of first elastic members 432 are spaced apart along the rotational direction of the central shaft 20, and an air channel 430 is formed between any two adjacent first elastic members 432. The plurality of first elastic members 432 and the plurality of micropores 412 are alternately spaced apart along the rotational direction of the central shaft 20, so that each air channel 430 is connected to a micropore 412.

[0044] The first elastic member 432 elastically presses against the end face of the sliding frame 41 away from the central axis 20, so that during the sliding process of the sliding frame 41, the sliding frame 41 presses against the first elastic member 432 and compresses the side toward the main member 431, so that the size of the air channel 430 gradually decreases until the end face of the sliding frame 41 away from the central axis 20 contacts the surface of the main member 431 away from the outer sheath 10 (that is, the first elastic member 432 is compressed to be completely located in the compression groove 4310), the air channel 430 is closed, and the micropore 412 is closed by the surface of the main member 431 away from the outer sheath 10, thereby improving the sealing performance of the sliding frame 41. On the one hand, it avoids the external environment of the sliding frame 41 from electromagnetic interference to the wire core 42 in the sliding frame 41, and on the other hand, it avoids water vapor that may penetrate into the outer sheath 10 from entering the sliding frame 41 through the micropore 412 and affecting the performance of the wire core 42.

[0045] It is understood that in other embodiments, the elastic structure 43 may also employ other structures, as long as it can undergo elastic deformation and, based on this elastic deformation, allows the airway 430 to be opened or closed. Furthermore, in addition to the first elastic member 432 being a compression spring as described above, the first elastic member 432 may also be an accessory made of an elastic material such as compressible silicone. For example, the elastic structure 43 includes a main member 431, which is made of an elastic material such as compressible silicone. In this case, the first elastic member 432 is integrally formed with the main member 431, and both are made of the same material. The main member 431 has a plurality of spaced grooves on the side facing away from the outer sheath 10. These grooves form the airway 430 for airflow, and a protrusion is formed between any two adjacent grooves. This protrusion serves as the first elastic member 432. As the sliding frame 41 slides, it presses against the protrusion of the main member 431, compressing it and causing it to deform circumferentially, gradually reducing the size of the airway 430 until it is closed.

[0046] Furthermore, considering the circumferential deformation of the protrusion, there may be a certain thickness, resulting in a certain gap between the main member 431 and the sliding frame 41. In some embodiments, the bottom wall of the groove may be provided with a blocking protrusion, the protrusion extending less than the length of the protrusion in its natural state. When the protrusion is compressed to a certain extent, the sliding frame 41 can abut against the blocking protrusion, thereby sealing the airway 430 through the blocking protrusion.

[0047] In this embodiment, the micropores 412 have a diameter of 50 nm to 100 nm. This ensures that hot air can enter the space within the sliding frame 41 through the micropores 412 to perform dehumidification. Furthermore, multiple micropores 412 with smaller diameters are used to form a micropore 412 shield on the end surface of the sliding frame 41 near the outer sheath 10, thereby further improving the electromagnetic interference resistance of the wire core 42 located within the sliding frame 41. Furthermore, the sliding frame 41 is made of metal, further improving the electromagnetic interference resistance of the wire core 42 located within the sliding frame 41.

[0048] It is understandable that the pore diameter of the micropore 412 may be 50 nm, 60 nm, 70 nm, 80 nm, 90 nm, 100 nm, etc.

[0049] Please combine again Figures 1 to 2 In one embodiment, the bracket 30 includes a first section 31 and a second section 32. Along the radial direction of the central axis 20, one end of the first section 31 is connected to the inner wall of the outer protective layer 10, and one end of the second section 32 is connected to the other end of the first section 31 away from the outer protective layer 10. The other end of the second section 32 abuts against the outer circumferential surface of the central axis 20, so that the second sections 32 of multiple brackets 30 abut against the central axis 20 along the radial direction of the central axis 20, thereby ensuring the stability of the central axis 20 during rotation.

[0050] It is understood that in other embodiments, the end of the second section 32 away from the first section 31 may also be spaced apart from the outer circumference of the central shaft 20. In this case, the sliding frame 41 can guide the rotation of the central shaft 20 to ensure its rotation stability.

[0051] The first section 31 is sandwiched between two adjacent elastic structures 43 and connected to the two adjacent elastic structures 43. The second section 32 can abut against the side wall of the sliding frame 41, so that the sliding frame 41 located between the two second sections 32 is clamped in the rotation direction of the central axis 20, thereby ensuring the stability of the sliding frame 41.

[0052] In this embodiment, receiving grooves 320 are respectively defined on opposite sides of the second portion 32 along the rotational direction of the central axis 20. The receiving grooves 320 communicate with the movable cavity 33. A second elastic member 50 is disposed within the receiving grooves 320 and is elastically compressed between the groove walls of the receiving groove 320 and the sliding frame 41.

[0053] Each group of accommodating grooves 21 includes a first accommodating groove 211 and a second accommodating groove 212 . Along the radial direction of the central axis 20 , the depth of the first accommodating groove 211 is greater than the depth of the second accommodating groove 212 .

[0054] When the abutting portion 411 is located in the first receiving groove 211, the first elastic member 432 is partially located outside the compression groove 4310 and abuts the sliding frame 41. The main member 431 is spaced apart from the sliding frame 41, allowing the air passage 430 to communicate with the micropores 412. This allows hot air to flow through the air passage 430 and the micropores 412 into the wire cavity 413 to dehumidify the wire core 42. Furthermore, when the abutting portion 411 is located in the first receiving groove 211, the second elastic member 50 is completely located within the receiving groove 320, and the sidewall of the sliding frame 41 directly abuts the side of the second section 32.

[0055] When the abutting portion 411 is located in the second receiving groove 212, the first elastic member 432 is compressed by the sliding frame 41, causing the main member 431 to abut against the sliding frame 41, thereby sealing the micro-hole 412. Furthermore, when the abutting portion 411 is located in the second receiving groove 212, the second section 32 is spaced apart from the sliding frame 41, and a portion of the second elastic member 50 is exposed outside the receiving groove 320 and elastically abuts against the sliding frame 41.

[0056] As the abutting portion 411 moves from the first receiving groove 211 to the second receiving groove 212, the central shaft 20 gradually pushes the sliding frame 41 to move radially away from the central shaft 20. During this process, gaps form between the side walls of the sliding frame 41 and the two adjacent second sections 32. These gaps widen as the sliding frame 41 slides, causing the second elastic member 50, which is elastically compressed within the receiving groove 320, to return to its original position, partially exiting the receiving groove 320 and abutting against the side walls of the sliding frame 41, thereby ensuring the stability of the sliding frame 41 during its sliding process. Furthermore, when the abutting portion 411 is located in the second receiving groove 212, the second elastic member 50 fills the gap between the sliding frame 41 and the second sections 32, thereby ensuring the stability of the sliding frame 41 after its position adjustment.

[0057] Further integration Figure 3 In this embodiment, each group of receiving grooves 21 further includes a transition groove 213. The transition groove 213 is located between the first receiving groove 211 and the second receiving groove 212 of the same group, and the transition groove 213 communicates with the adjacent first receiving groove 211 and the second receiving groove 212. When the abutting portion 411 moves from the first receiving groove 211 to the second receiving groove 212, the abutting portion 411 can move within the transition groove 213, thereby preventing the abutting portion 411 from abutting against the outer circumference of the central shaft 20 after being separated from the first receiving groove 211, thereby preventing the sliding frame 41 from being too tightly pressed against the main body 431.

[0058] The depth of the transition groove 213 is slightly smaller than that of the second receiving groove 212 , so as to form a certain slope at the connection between the transition groove 213 and the second receiving groove 212 to prevent the abutting portion 411 entering the second receiving groove 212 from leaving.

[0059] It is worth noting that the supporting portion 411 can be made of a material with a certain elasticity, such as rubber, so that the supporting portion 411 can be slightly squeezed and deformed to pass over the slope between the transition groove 213 and the second receiving groove 212 and enter the second receiving groove 212 .

[0060] In this embodiment, the bracket 30 is made of metal, which has a certain electromagnetic shielding function and can further enhance the electromagnetic shielding protection of the cores 42 located in the different sliding frames 41. The second elastic member 50 is made of an elastic material with certain water absorption properties, such as sponge. While providing elastic support for the sliding frames 41, the second elastic member 50 can also absorb water that leaks or accumulates along the surface of the sliding frames 41, further enhancing the radial water resistance of the network cable.

[0061] Furthermore, in other embodiments, each group of receiving slots 21 may include at least three receiving slots 21. When the abutting portion 411 is located in one of the three receiving slots 21, a gap exists between the main member 431 and the sliding frame 41, thereby opening the airway 430. When the abutting portion 411 is located in the other two of the three receiving slots 21, the main member 431 abuts against the sliding frame 41, thereby closing the airway 430. By varying the depths of the two receiving slots 21, the sliding frame 41 can have different radial dimensions relative to the central axis 20, thereby accommodating sliding frames 41 of different sizes. Furthermore, since the wire core 42 is confined within the sliding frame 41, sliding frames 41 of different sizes can accommodate wire cores 42 of different sizes. This allows the wire cores 42 of different sizes to be accommodated while maintaining the dimensions of the outer sheath 10, thereby improving the adaptability of the network cable.

[0062] Please combine again Figures 1 to 4 In one embodiment, the outer sheath 10 includes a shielding layer 11 and an outer jacket 12, arranged from the inside out. The shielding layer 11 can be a structure with electromagnetic shielding capabilities, such as a woven metal mesh, while the outer jacket 12 can be made of a material such as vinyl chloride. The shielding layer 11 is a circular ring structure with a housing 101 formed therein. The elastic structure 43 is connected to the inner circumference of the shielding layer 11. The outer jacket 12 is disposed around the outer circumference of the shielding layer 11.

[0063] In other embodiments, the outer protective layer 10 further includes a water-blocking tape, which may be disposed between the shielding layer 11 and the outer jacket 12 to improve the waterproof capability of the outer protective layer 10 .

[0064] In this embodiment, the network cable 100 with a dehumidification function further includes two connecting ends 60, which are respectively connected to the two ends of the outer sheath 10 to enclose the accommodating cavity 101 and the wire cavity 413. In addition, each wire core 42 can be connected to other electronic devices through the two connecting ends 60 to achieve signal transmission.

[0065] The connecting end 60 is detachably connected to the outer sheath 10 so that when the network cable 100 with a dehumidification function needs to be dehumidified, the connecting end 60 can be removed to expose the central axis 20, and the network cable 100 with a dehumidification function can be straightened and the central axis 20 can be rotated to drive the sliding frame 41 to move.

[0066] Of course, in other embodiments, the network cable 100 with a dehumidification function may not include the two connecting ends 60, that is, the network cable 100 with a dehumidification function is a semi-finished product stored in a warehouse. Before connecting the two connecting ends 60, it can be dehumidified first to avoid it getting damp during storage and affecting subsequent work performance.

[0067] In other embodiments, a through-hole may be provided at the center of the central shaft 20, extending from the end surface of one end of the central shaft 20 to the end surface of the other end of the central shaft 20 along the extension direction of the central shaft 20. The through-hole allows a rotating shaft to pass through, so that after removing the connecting end portion 60, the rotating shaft is inserted into the through-hole, and the rotating shaft drives the central shaft 20 to rotate. For example, a compression spring may be provided on the outer circumference of the rotating shaft, with one end of the compression spring connected to the rotating shaft and the other end connected to a suction cup. The compression spring is compressed and placed together with the suction cup into the through-hole. Subsequently, the compression spring resets, causing the suction cup to adhere to the inner wall of the central shaft 20, thereby fixing the central shaft 20 relative to the rotating shaft, and the rotating shaft then drives the central shaft 20 to rotate.

[0068] The specific embodiments of the present application have been described above with reference to the accompanying drawings. However, those skilled in the art will appreciate that various modifications and substitutions may be made to the specific embodiments of the present application without departing from the scope of the present application. Such modifications and substitutions are within the scope of the present application.
