[0015] In a possible embodiment, the outer circumferential surface of the central shaft is provided with a plurality of groups of receiving grooves, the plurality of groups of receiving grooves being provided correspondingly to the plurality of sliding assemblies, and along the radial direction of the central shaft, an end of the sliding frame close to the central shaft is provided with a protruding supporting portion;

[0016] Each group of the accommodating grooves includes a plurality of accommodating grooves, and the accommodating grooves are used to accommodate the supporting parts. Along the rotation direction of the central axis, the plurality of accommodating grooves are arranged at intervals, and the groove depths of the plurality of accommodating grooves increase linearly.

[0017] In a possible implementation, each group of the accommodating grooves includes a first accommodating groove and a second accommodating groove, and along the radial direction of the central axis, the depth of the first accommodating groove is greater than the depth of the second accommodating groove;

In addition, unless explicitly defined herein, terms such as those defined in common dictionaries should be interpreted as having a meaning consistent with their meaning in the relevant art and the context of this application, and will not be interpreted as idealized or overly formal meanings.

[0034] The specific implementation methods of the present application will be described in further detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 4 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 .

[0036] The outer sheath 10 defines a housing cavity 101, within which the central shaft 20 is rotatably mounted. The central shaft 20 is coaxial with the outer sheath 10, with its axis oriented in the same direction as the extension of the dehumidifying network cable 100. Multiple brackets 30 are equally spaced around the outer circumference of the central shaft 20, forming a movable cavity 33 between any two adjacent brackets 30. The brackets 30 extend parallel to the radial direction of the central shaft 20, with one end of each bracket connected to the inner wall of the outer sheath 10.

[0037] The number of sliding components 40 is set to be multiple, and each active cavity 33 has a sliding component 40. The sliding component 40 includes a sliding frame 41, a wire core 42 and an opening and closing structure 43. Along the radial direction of the central axis 20, the sliding frame 41 is slidably arranged in the active cavity 33, and a wire cavity 413 is opened in the sliding frame 41, and the wire core 42 is arranged in the wire cavity 413. Along the radial direction of the central axis 20, an air hole 412 is opened at one end of the sliding frame 41 close to the outer sheath 10, and the air hole 412 is connected to the wire cavity 413, and a sliding portion 45 is protruded at one end of the sliding frame 41 close to the outer sheath 10, and an air channel 4150 (such as Figure 3 (as shown). The opening and closing structure 43 includes two opening and closing members 431, which are located on opposite sides of the sliding portion 45 along the rotation direction of the central shaft 20. Both opening and closing members 431 can rotate around the outer circumference of the central shaft 20 along the rotation direction of the central shaft 20. In the radial direction of the central shaft 20, the opening and closing members 431 are spaced apart from the outer sheath 10, forming a first air cavity 434 therebetween, which allows for the circulation of hot air.

[0038] The sliding frame 41 has at least a defined first state and a second state. When the central shaft 20 rotates, the central shaft 20 can abut against the sliding frame 41 to move radially along the central shaft 20, thereby switching the sliding frame 41 between the first and second states. When the sliding frame 41 is in the first state, the sliding frame 41 is spaced apart from the opening and closing member 431, and the first air cavity 434 is connected to the air hole 412 through the air passage 4150. When the sliding frame 41 is in the second state, the sliding frame 41 abuts against the opening and closing member 431, and the opening and closing member 431 seals the air hole 412. The first air cavity 434 is filled with a filter element. The filter element is a material with a filtering function, such as filter cloth, which can filter the hot air flow entering the first air cavity 434 to prevent impurities carried in the hot air flow from entering the wire cavity 413 through the air hole 412 and affecting the operation of the wire core 42.

[0039] Thus, in the network cable 100 with a dehumidification function of the present application, the rotation of the central axis 20 drives the sliding frame 41 to slide radially along the central axis 20 within the active cavity 33, so that the outer diameter of the inner sheath formed by the multiple sliding components 40 can be adjusted to adapt to different usage requirements. In addition, when the sliding frame 41 slides radially along the central axis 20, the sliding frame 41 abuts against the opening and closing member 431 to open or close the opening and closing member 431, thereby achieving communication between the air hole 412 and the first air cavity 434. When the network cable needs to be dehumidified, the first air cavity 434 is connected to the air hole 412 by rotating the central axis 20, and hot air is injected into the first air cavity 434 from the outside. The hot air then enters the line cavity 413 from the air hole 412, thereby dehumidifying the internal space of the network cable and ensuring that the network cable can operate normally. After dehumidification is completed, the central shaft 20 is rotated again so that the first air cavity 434 and the air hole 412 are no longer in a connected state, and the air hole 412 is closed by the opening and closing member 431, thereby ensuring the waterproof sealing performance and electromagnetic shielding performance of the sliding frame 41 and ensuring the normal operation of the network cable.

[0040] Please combine again Figures 1 to 4 In one embodiment, the central shaft 20 is a cylindrical structure, and a plurality of receiving grooves 21 are defined on its outer circumference. The plurality of receiving grooves 21 are correspondingly disposed 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 at one end proximate to the central shaft 20. The abutment 411 is located approximately midway between the end of the sliding frame 41 proximate to the central shaft 20.

[0041] 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.

[0042] 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°.

[0043] 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.

[0044] 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 44 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 44 abutted by the sliding frame 41 to undergo different degrees of elastic deformation.

[0045] 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.

[0046] 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.

[0047] 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 sheath 10 , and multiple micropores are evenly spaced on the end surface of the sliding frame 41 away from the central axis 20 .

[0048] 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.

[0049] In addition, the sliding frame 41 is made of metal, which can improve the anti-electromagnetic interference capability of the wire core 42 located in the sliding frame 41 .

[0050] Please combine again Figures 1 to 4 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.

[0051] 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.

[0052] Along the rotation direction of the central shaft 20 , the second sections 32 can abut against the sidewalls of the sliding frame 41 , so that the two second sections 32 can clamp the sliding frame 41 therebetween in the rotation direction of the central shaft 20 , thereby ensuring the stability of the sliding frame 41 .

[0053] 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 third 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.

[0054] Please combine again Figures 1 to 4 In one embodiment, the sliding assembly 40 further includes an elastic structure 44. The elastic structure 44 includes a guide seat 441 and a first elastic member 442. The guide seat 441 extends in a direction parallel to the radial direction of the central axis 20. One end of the guide seat 441 is connected to the inner wall of the outer sheath 10, and the other end defines a guide groove 4410. The guide groove 4410 extends in a direction parallel to the radial direction of the central axis 20.

[0055] In this embodiment, the sliding portion 45 includes a sliding main portion 414 and two elastic protrusions 415. The sliding main portion 414 extends parallel to the radial direction of the central axis 20, and one end of the sliding main portion 414 is connected to the surface of the sliding frame 41 on the side away from the central axis 20. The two elastic protrusions 415 are respectively connected to opposite sides of the sliding main portion 414 in the rotation direction of the central axis 20.

[0056] The end of the sliding body 414 away from the sliding frame 41 is slidably received in the guide groove 4410. The first elastic member 442 is located in the guide groove 4410. The first elastic member 442 is a compression spring. One end of the first elastic member 442 is elastically connected to the bottom wall of the guide groove 4410. The other end of the first elastic member 442 is elastically connected to the end of the sliding body 414 away from the sliding frame 41, thereby providing an elastic force for the sliding body 414 to move toward the central axis 20.

[0057] Thus, when the abutting portion 411 enters the receiving groove 21 with a smaller depth from the deeper receiving groove 21, the sliding frame 41 moves toward the side away from the central axis 20, and the sliding body 414 continues to compress the first elastic member 442. When the abutting portion 411 enters the receiving groove 21 with a larger depth from the smaller depth, the first elastic member 442 returns to its original position and applies an elastic force to the sliding body 414, thereby pushing the sliding frame 41 toward the central axis 20 through the sliding body 414 until the abutting portion 411 abuts against the bottom wall of the receiving groove 21.

[0058] Please combine again Figures 1 to 4 In one embodiment, the opening and closing structure 43 further includes two sliding seats 432. Along the rotation direction of the central axis 20, the two sliding seats 432 are arranged on opposite sides of the guide seat 441. One end of the sliding seat 432 is connected to the first section 31 of the adjacent bracket 30, and the other end of the sliding seat 432 is spaced apart from the guide seat 441, and the first air cavity 434 is located between the sliding seat 432 and the guide seat 441. In addition, along the radial direction of the central axis 20, the side of the sliding seat 432 away from the central axis 20 is connected to the outer sheath 10, so that the sliding seat 432 can cooperate with the bracket 30 to support the outer sheath 10, thereby improving the stability and uniformity of the support of the inner layer structure of the network cable located within the outer sheath 10 on the outer sheath 10.

[0059] The sliding seat 432 defines a sliding groove 4320. One end of the opening and closing member 431 is slidably received within the sliding groove 4320. The other end of the opening and closing member 431 is configured to abut against the sliding body 414 or the elastic protrusion 415. Along the radial direction of the central shaft 20, the sliding groove 4320 extends from the surface of the sliding seat 432 on the side away from the outer sheath 10 toward the outer sheath 10. Furthermore, along the rotational direction of the central shaft 20, the sliding groove 4320 extends from the end surface of the sliding seat 432 proximal to the guide seat 441 toward the side away from the guide seat 441, thereby forming a first groove wall P1 and a second groove wall P2 within the sliding groove 4320.

[0060] The first groove wall P1 is a curved surface, and its shape matches the shape of the outer sheath 10. The opening and closing member 431 can slide along the first groove wall P1, thereby guiding the opening and closing member 431 to slide along the rotational direction of the central axis 20. It is understood that one of the first groove wall P1 and the surface of the opening and closing member 431 on the side near the first groove wall P1 can be provided with a sliding protrusion, and the other can be provided with a sliding groove. The sliding protrusion slidably cooperates with the sliding groove, thereby ensuring that the opening and closing member 431 can slide relative to the first groove wall P1.

[0061] In addition, along the radial direction of the central axis 20, the surface of the opening and closing member 431 on the side close to the central axis 20 is coplanar with the surface of the sliding seat 432 on the side close to the central axis 20, so as to ensure that when the opening and closing member 431 presses against the surface of the sliding frame 41 to close the air hole 412, the sliding seat 432 also presses against the surface of the sliding frame 41 to ensure that no gap is formed between the two.

[0062] In this embodiment, the opening and closing structure 43 also includes a second elastic member 433. The second elastic member 433 is a compression spring, and the second elastic member 433 is arranged along the rotation direction of the central axis 20. One end of the second elastic member 433 is elastically connected to the second groove wall P2, and the other end of the second elastic member 433 is elastically connected to the end of the opening and closing member 431 away from the guide seat 441, which is used to provide an elastic force for the opening and closing member 431 to move toward the sliding main body 414. In this way, when the sliding portion 45 abuts the two opening and closing members 431 through the elastic protrusion 415 and causes them to move away from each other, the opening and closing member 431 continues to compress the second elastic member 433. Subsequently, when the sliding portion 45 no longer abuts the opening and closing members 431 through the elastic protrusion 415, the second elastic member 433 returns to its original position and pushes the opening and closing member 431 toward the guide seat 441 until it abuts against the surface of the guide seat 441.

[0063] It is understood that in other embodiments, the opening and closing structure 43 may not be provided with the second elastic member 433, and the opening and closing structure 43 includes an opening and closing member 431 and a sliding seat 432. The installation position of the sliding seat 432 is the same as described above. The opening and closing member 431 is made of a material such as compressible silicone, and the sliding seat 432 is provided with a compression groove. The opening and closing member 431 is partially compressibly accommodated in the compression groove to limit the compression path of the opening and closing member 431 through the compression groove. One end of the opening and closing member 431 is exposed in the compression groove and is used to abut the sliding main body 414 or the elastic protrusion 415, thereby realizing the connection or disconnection of the air path between the air hole 412 and the first air cavity 434.

[0064] Please combine again Figures 1 to 4In one embodiment, along the rotational direction of the central shaft 20, the sliding body 414 is located approximately in the middle of the surface of the sliding frame 41 on the side closest to the outer sheath 10. An air passage 4150 is defined in the elastic protrusion 415. The air passage 4150 extends radially along the central shaft 20 from the side of the elastic protrusion 415 closest to the outer sheath 10 to the side of the elastic protrusion 415 closest to the sliding frame 41.

[0065] In this embodiment, the sliding seat 432 is made of an insulating material, and the opening and closing member 431 is made of a metal material. The portion of the sliding frame 41 corresponding to the air hole 412 is abutted by the opening and closing member 431, thereby sealing the air hole 412. Furthermore, since the opening and closing member 431 is made of a metal material, when sealing the air hole 412, it not only ensures that the air path is disconnected but also provides electromagnetic shielding for the space surrounding the air hole 412, thereby ensuring the electromagnetic shielding performance of the sliding frame 41.

[0066] The elastic protrusion 415 is made of an elastic material such as rubber, and has a substantially semicircular cross-section. A sealing portion 4310 is provided at one end of the opening and closing member 431, adjacent to the guide seat 441. The sealing portion 4310 is made of an elastic material such as rubber, and has a substantially isosceles trapezoidal cross-section. The sealing portion 4310 has a supporting surface P3 and two guide surfaces P4. The supporting surface P3 is parallel to the protruding direction of the sliding main body 414. The supporting surface P3 is used to support the surface of the elastic protrusion 415 or the sliding main body 414. Since the sealing portion 4310 is made of an elastic material such as rubber, when the supporting surface P3 is in contact with the surface of the sliding main body 414, a seal is formed between the supporting surface P3 and the sliding main body 414 to ensure the sealing and electromagnetic shielding properties of the space in which the sliding frame 41 is located. Along the protruding direction of the sliding body 414, two guide surfaces P4 are connected to the two ends of the abutting surface P3, and the two guide surfaces P4 are arranged at an angle relative to the abutting surface P3. The inclined guide surfaces P4 can guide the elastic protrusion 415 to pass over the area where the guide surfaces P4 are located, pushing the opening and closing member 431 to move away from the sliding body 414, thereby causing the abutting surface P3 to abut against the elastic protrusion 415. In addition, the sealing portion 4310 is made of an elastic material, which also facilitates the elastic protrusion 415 to pass over the sealing portion 4310.

[0067] It is worth noting that along the protruding direction of the sliding main body 414, sufficient space is left between the guide seat 441 and the opening and closing member 431 to accommodate the elastic protrusion 415 that passes over the sealing portion 4310, thereby preventing the elastic protrusion 415 from abutting against the guide seat 441 and restricting the sliding of the sliding main body 414.

[0068] In this embodiment, each set of receiving grooves 21 includes a first receiving groove 211 and a second receiving groove 212. Along the radial direction of the central axis 20, the depth of the first receiving groove 211 is greater than the depth of the second receiving groove 212. When the abutting portion 411 is located in the first receiving groove 211, the sliding frame 41 is in the first state. When the abutting portion 411 is located in the second receiving groove 212, the sliding frame 41 is in the second state.

[0069] When the abutting portion 411 is located in the first receiving groove 211 , the third elastic member 50 is completely located in the receiving groove 320 , and the side wall of the sliding frame 41 directly abuts against the side surface of the second section 32 .

[0070] When the resisting 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 third elastic member 50 is exposed outside the receiving groove 320 and elastically resists the sliding frame 41 .

[0071] 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 gradually increase as the sliding frame 41 slides. The third elastic member 50, elastically compressed within the receiving groove 320, begins 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 third 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.

[0072] Furthermore, when the sliding frame 41 is in the first state, the elastic protrusion 415 abuts against the abutting surface P3, the sliding frame 41 and the opening and closing member 431 are spaced apart in the radial direction of the central axis 20, and a second air cavity 435 is formed between the sliding frame 41 and the opening and closing member 431. The first air cavity 434 is connected to the second air cavity 435 through the air channel 4150, and the hot air flows from the first air cavity 434 through the air channel 4150 into the second air cavity 435, and then enters the line cavity 413 through the air hole 412.

[0073] When the sliding frame 41 is in the second state, the elastic protrusion 415 is located on the side of the opening and closing member 431 closest to the outer cover 10, and the abutment surface P3 abuts the surface of the sliding body 414, thereby creating a seal between the opening and closing member 431 and the sliding body 414. Furthermore, when the sliding frame 41 is in the second state, portions of the sliding seat 432 and the opening and closing member 431 abut against the surface of the sliding frame 41, completely covering the surface of the sliding frame 41.

[0074] Further integration Figure 5 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. The transition groove 213 connects 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. This prevents 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 opening and closing member 431.

[0075] 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.

[0076] 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 .

[0077] 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 third 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 third 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.

[0078] 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, the abutting surface P3 abuts against the elastic protrusion 415, thereby connecting the first air cavity 434 with the second air cavity 435. When the abutting portion 411 is located in the other two of the three receiving slots 21, the abutting surface P3 abuts against the surface of the sliding body 414, disconnecting the first air cavity 434 from the air hole 412. By varying the depths of the two receiving slots 21, the sliding frame 41 can have different radial dimensions in the central axis 20, thereby accommodating sliding frames 41 of different sizes. Furthermore, since the wire core 42 is constrained within the sliding frame 41, sliding frames 41 of different sizes can accommodate wire cores 42 of different sizes. This allows the cable to accommodate wire cores 42 of different sizes while maintaining the same size of the outer sheath 10, thereby improving the adaptability of the network cable.

[0079] Please combine again Figure 6 , and see Figures 1 to 2In 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 44 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.

[0080] 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 .

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.
