[0027] The following further describes in detail the specific embodiments of the present application with reference to the accompanying drawings.

[0028] As Figures 1 to 4 shown, this embodiment provides a network cable 100 with a dehumidification function, including an outer protective layer 10, a central axis 20, a plurality of brackets 30, and a plurality of sliding components 40.

[0029] An accommodation cavity 101 is provided inside the outer protective layer 10, and the central axis 20 is rotatably arranged inside the accommodation cavity 101. The central axis 20 is coaxially arranged with the outer protective layer 10, and the direction of the axis of the central axis 20 is the same as the extending direction of the network cable 100 with a dehumidification function. A plurality of brackets 30 are arranged at equal intervals around the outer peripheral surface of the central axis 20, and an activity cavity 33 is formed between any two adjacent brackets 30. The extending 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 protective layer 10.

[0030] Each activity cavity 33 is provided with 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 inside the activity cavity 33, a wire cavity 413 is opened inside the sliding frame 41, and the wire core 42 is arranged inside the wire cavity 413. Along the radial direction of the central axis 20, a first air hole 412 is opened at one end of the sliding frame 41 close to the outer protective layer 10, and the first air hole 412 communicates with the wire cavity 413. Along the radial direction of the central axis 20, the opening and closing structure 43 is arranged at an interval from the outer protective layer 10 and a first air cavity 434 is formed therebetween for hot air to flow through. In addition, a second air cavity 435 communicating with the first air hole 412 can be formed between the opening and closing structure 43 and the sliding frame 41. A support cavity 34 is provided between any adjacent bracket 30 and the sliding frame 41, and a second air hole 310 is opened on the bracket 30, and the second air hole 310 communicates with the support cavity 34 and the second air cavity 435.

[0031] When the central axis 20 rotates, the central axis 20 can abut against the sliding frame 41 and slide along the radial direction of the central axis 20. Based on the sliding action of the sliding frame 41, the sliding frame 41 can control the on-off of the air path between the first air cavity 434 and the second air cavity 435.

[0032] In this embodiment, the sliding carriage 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 carriage 41 to move it radially along the central shaft 20, so that the sliding carriage 41 can be switched between the first state and the second state. When the sliding carriage 41 is in the first state, the first air chamber 434 is in gas communication with the second air chamber 435. When the sliding carriage 41 is in the second state, the gas path between the first air chamber 434 and the second air chamber 435 is disconnected.

[0033] Thus, in the network cable 100 with a dehumidification function of the present application, the rotation of the central shaft 20 drives the sliding carriage 41 to slide radially along the central shaft 20 within the movable cavity 33, so that the outer diameter of the inner protective layer formed by the plurality of sliding components 40 can be adjusted to adapt to different usage requirements. In addition, when the sliding carriage 41 slides radially along the central shaft 20, the sliding carriage 41 can control the on-off of the gas path between the first air chamber 434 and the second air chamber 435. When it is necessary to dehumidify the network cable, the central shaft 20 is rotated to connect the first air chamber 434 and the second air chamber 435, and hot air is injected into the first air chamber 434 from the outside. The hot air then enters the wire cavity 413 through the first air holes 412, thereby performing a dehumidification operation on the internal space of the network cable to ensure the stable operation of the network cable. At the same time, part of the air flow can also enter the support cavity 34 through the second air holes 310, and then the outer wall of the sliding carriage 41 and the area between the sliding carriage 41 and the central shaft 20 are dehumidified by the hot air flow. After the dehumidification is completed, the central shaft 20 is rotated again so that the first air chamber 434 and the second air chamber 435 are no longer in communication, and the first air holes 412 are closed by the opening and closing structure 43, thereby ensuring the waterproof sealing performance and electromagnetic shielding performance of the sliding carriage 41 and guaranteeing the performance of the network cable.

[0034] Please also combine Figures 1 to 4 In an embodiment, the central shaft 20 is a cylindrical structure, and a plurality of sets of receiving grooves 21 are formed on the outer peripheral surface of the central shaft 20. The plurality of sets of receiving grooves 21 are correspondingly arranged with the plurality of sliding components 40. Radially along the central shaft 20, one end of each sliding carriage 41 close to the central shaft 20 protrudes with a abutting portion 411, and the abutting portion 411 is generally located at the middle position of one end of the sliding carriage 41 close to the central shaft 20.

[0035] Each set of receiving grooves 21 includes a plurality of receiving grooves 21 for receiving the abutting portion 411. Along the rotation direction of the central shaft 20, the receiving grooves 21 in each set are spaced apart. The central shaft 20 is made of a material such as rubber to ensure that the central shaft 20 can bend with the network cable, and the central shaft 20 has a certain structural strength to ensure that the groove wall of the receiving groove 21 of the central shaft 20 can abut against the abutting portion 411 and apply a force to the abutting portion 411 to push the sliding carriage 41 to move.

[0036] In this embodiment, the number of brackets 30 is four. Along the rotation direction of the central axis 20, the four brackets 30 are arranged at intervals in sequence, and the included angle between any two adjacent brackets 30 is 90°. The number of the abutting parts 411 is set to four, and the included angle between any two adjacent abutting parts 411 is also 90°.

[0037] It can be understood that in other embodiments, the number of the sliding assemblies 40 can also be set to other numbers, and the specific number can be selected according to actual design requirements.

[0038] Along the radial direction of the central axis 20, the receiving groove 21 is formed by inwardly recessing from the outer peripheral surface of the central axis 20. The receiving groove 21 is used to receive the abutting part 411, and the abutting part 411 can abut against the bottom wall of the receiving groove 21, so as to clamp the sliding frame 41 between the elastic structure 44 and the central axis 20, so as to realize the radial limit of the sliding frame 41. Along the rotation direction of the central axis 20, the receiving grooves 21 in the same group are arranged at intervals, and the groove depths of the receiving grooves 21 increase linearly. The groove depths of the receiving grooves 21 are different, so that when the abutting part 411 is located in different receiving grooves 21, the distance between the sliding frame 41 and the central axis 20 is different along the radial direction of the central axis 20, so that the elastic structure 44 abutted by the sliding frame 41 can undergo different degrees of elastic deformation.

[0039] In this embodiment, the cross-sectional shape of the abutting part 411 is generally semi-circular, and the shape of the receiving groove 21 is adapted to the shape of the abutting part 411 to ensure the stability of the limit of the sliding frame 41 by the abutting part 411 when the abutting part 411 is located in the receiving groove 21 and ensure that the sliding frame 41 does not shake. In addition, the cross-sectional shape of the abutting part 411 is semi-circular, and the shape of the receiving groove 21 is adapted to the shape of the abutting part 411, so as to guide the abutting part 411 in and out of the receiving groove 21 through the curved surface, so as to ensure that the abutting part 411 can easily disengage from the receiving groove 21.

[0040] The cross-sectional shape of the sliding frame 41 is generally fan-shaped. Along the radial direction of the central axis 20, the shape of the end face of the end of the sliding frame 41 close to the central axis 20 is adapted to the outer peripheral surface of the central axis 20, so as to ensure that when the central axis 20 rotates to make the abutting part 411 abut against the bottom wall of different receiving grooves 21 and the sliding frame 41 slides, the sliding frame 41 can slide along the radial direction of the central axis 20.

[0041] Along the radial direction of the central axis 20, the shape of the end face of the end of the sliding frame 41 far from the central axis 20 is adapted to the inner peripheral surface of the outer protective layer 10, and a plurality of micropores are evenly opened on the end face of the end of the sliding frame 41 far from the central axis 20.

[0042] The core 42 includes two conductors 421 and an insulating layer 422. The conductors 421 are made of metal materials such as copper or aluminum, and the insulating layer 422 is made of insulating materials such as polyethylene. Along the radial direction of the central axis 20, the opposite sides of the core 42 are respectively abutted against the inner walls of the opposite sides of the sliding frame 41 to realize the radial limit of the core 42 with respect to the central axis 20. In addition, the sliding frame 41 is filled with a filler, which can be a filling rope or the like. Along the rotational direction of the central axis 20, the filler is filled in the space between the core 42 and the inner walls of the opposite sides of the sliding frame 41 to realize the limit of the core 42 in the rotational direction of the central axis 20, so as to ensure that the core 42 will not shake or the like inside the sliding frame 41.

[0043] In addition, the sliding frame 41 is made of metal material, which can improve the electromagnetic interference resistance of the core 42 located inside the sliding frame 41.

[0044] Please further combine with Figures 1 to 3 In an embodiment, the bracket 30 is arranged along the radial direction of the central axis 20, and the bracket 30 includes a first section 31 and a second section 32. One end of the first section 31 is connected to the inner wall of the outer sheath 10, one end of the second section 32 is connected to the end of the first section 31 far from the outer sheath 10, and the other end of the second section 32 can contact the outer surface of the central axis 20, so that the position of the central axis 20 is not likely to shift during rotation by limiting the central axis 20 through the second section 32. The width of the second section 32 is smaller than the width of the first section 31, and the second section 32 is generally connected to the middle position of the end of the first section 31 far from the outer sheath 10. Along the rotational direction of the central axis 20, the second section 32 and the sliding frame 41 are arranged at intervals and form the above-mentioned support cavity 34 therebetween.

[0045] The network cable 100 with dehumidification function further includes a plurality of support components 50, and one support component 50 is arranged in each support cavity 34. One end of the support component 50 is elastically supported on the sliding frame 41, and the other end thereof is elastically connected to the bracket 30. The bracket 30 is provided with a second air hole 310, and the first air cavity 434 can communicate with the support cavity 34 through the second air hole 310, and the support component 50 can open or close the second air hole 310.

[0046] The support assembly 50 includes a support member 51 and a third elastic member 52. The support member 51 is located in the support cavity 34 and is configured to abut against the side wall of the sliding carriage 41. The third elastic member 52 is elastically connected between the support member 51 and the second section 32. Along the rotation direction of the central axis 20, guiding protrusions 320 are convexly provided on both opposite sides of the second section 32. The extending direction of the guiding protrusions 320 is perpendicular to the extending direction of the second section 32. The third elastic member 52 is a compression spring, and the third elastic member 52 is sleeved on the outer periphery of the guiding protrusion 320 to guide the deformation path of the third elastic member 52 through the guiding protrusion 320. One end of the third elastic member 52 is elastically connected to the second section 32, and the other end thereof is elastically connected to the side of the support member 51 away from the sliding carriage 41 that it abuts against. In this way, when the sliding carriage 41 moves toward the side away from the central axis 20, the distance between the sliding carriage 41 and the second section 32 becomes larger, and the third elastic member 52 resets to generate an elastic force, thereby pushing the support member 51 to move toward the sliding carriage 41, ensuring that the support member 51 always abuts against the side wall of the sliding carriage 41 during the movement of the sliding carriage 41, so as to ensure the stability of the sliding carriage 41 during the sliding process.

[0047] In this embodiment, a second air hole 310 is formed in the first section 31. When the sliding carriage 41 is in the first state, the first end of the second air hole 310 communicates with the first air cavity 434, and the second end of the second air hole 310 communicates with the support cavity 34. When the support member 51 moves toward the side away from the second section 32, the support member 51 can close the opening of the second air hole 310 at the second end.

[0048] Specifically, the second air hole 310 is generally arranged in an "L" shape. The first end of the second air hole 310 is located on the side wall of the first section 31, and the second end of the second air hole 310 is located on the end face of the first section 31 near the second section 32. When the sliding carriage 41 is in the first state, the sliding carriage 41 and the opening and closing member 431 of the opening and closing structure 43 are spaced apart in the radial direction of the central axis 20, and a second air cavity 435 is formed between the sliding carriage 41 and the opening and closing member 431. The first air cavity 434 communicates with the second air cavity 435 through an air passage 4150. At this time, the first end of the second air hole 310 communicates with the second air cavity 435, thereby realizing the communication of the second air hole 310 with the first air cavity 434 through the second air cavity 435 and the air passage 4150, so that the hot air flow in the first air cavity 434 can flow to the first end of the second air hole 310, and then enter the support cavity 34 from the second end of the second air hole 310.

[0049] The support member 51 includes a support portion 511 and two extension portions 512. The extending direction of the support portion 511 is parallel to the extending direction of the second zone portion 32, and the two extension portions 512 are integrally formed at opposite ends of the support portion 511 respectively. One side of the support portion 511 abuts against the side wall of the sliding frame 41, and one end of the third elastic member 52 away from the second zone portion 32 is connected to the other side of the support portion 511.

[0050] The extension portion 512 includes a first extension segment 5121, a second extension segment 5122, and a third extension segment 5123 connected in sequence. The extending direction of the first extension segment 5121 is perpendicular to the extending direction of the support portion 511, and one end of the first extension segment 5121 away from the second extension segment 5122 is connected to the support portion 511. The extending direction of the second extension segment 5122 is parallel to the extending direction of the support portion 511, and the extending direction of the third extension segment 5123 is perpendicular to the extending direction of the support portion 511. The third extension segment 5123 of the upper extension portion 512 abuts against the end face of one end of the first zone portion 31 close to the second zone portion 32, for closing the opening of the second end of the second air hole 310.

[0051] A plurality of first ventilation holes 5110 are formed in the support portion 511, and a second ventilation hole 51210 is formed in the first extension segment 5121. When the sliding frame 41 is in the first state, the third extension segment 5123 is located on the side of the second end of the second air hole 310 close to the second zone portion 32. At this time, the third extension segment 5123 does not close the opening of the second end of the second air hole 310. After the hot air flow leaves from the second end of the second air hole 310, it enters the cavity between the two extension portions 512 through the second ventilation hole 51210, and then acts on the outer wall of the sliding frame 41 through the first ventilation hole 5110. In addition, part of the hot air flow can also enter the area between the sliding frame 41 and the central axis 20 through the second ventilation hole 51210 on the lower extension portion 512, so as to realize the transportation of the hot air flow to each area in the outer protective layer 10.

[0052] When the sliding frame 41 is switched from the first state to the second state, under the action of the elastic force of the third elastic member 52, the third extension segment 5123 slides toward the side away from the second zone portion 32. When the sliding frame 41 is in the second state, the third extension segment 5123 moves to the opening of the second end of the second air hole 310, thereby closing the opening of the second end of the second air hole 310, so as to realize the isolation of the radial and circumferential spaces of the sliding frame 41, improve the waterproofness of the sliding frame 41, and avoid signal crosstalk between the wire cores 42 in two adjacent sliding frames 41.

[0053] In addition, when the dehumidification operation is completed, the central shaft 20 is rotated to switch the sliding frame 41 from the first state to the second state. During this process, the sliding frame 41 moves radially away from the central shaft 20 along the central shaft 20, and a gap will gradually appear between the sliding frame 41 and the first zone 31, so that the sliding frame 41 no longer closes the opening at the first end of the second air hole 310. And during the process of the sliding frame 41 moving radially away from the central shaft 20 along the central shaft 20, the sliding frame 41 gradually approaches the opening and closing member 431, so that the volume of the second air chamber 435 gradually decreases. Part of the gas will enter the first air chamber 434, and part of the gas will enter the second air hole 310 from the opening at the first end of the second air hole 310, and then enter the support chamber 34 through the second air hole 310, resulting in part of the air flow flowing back to the area between the sliding frame 41 and the central shaft 20. On the one hand, it affects the discharge efficiency of the air flow, and on the other hand, it will cause the air pressure at the central shaft 20 to become high and affect the stability of the internal structure. Therefore, during the process of the sliding frame 41 moving radially away from the central shaft 20 along the central shaft 20, through the cooperation of the support member 51 and the third elastic member 52, after the sliding frame 41 leaves the position where it is in the first state, the support member 51 always abuts against the side wall of the sliding frame 41, and the support member 51 always closes the opening at the second end of the second air hole 310, ensuring that the gas at the second air chamber 435 is discharged to the first air chamber 434, and then can be discharged to the outside of the wire.

[0054] Please combine with Figures 1 to 5 In an 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 extending direction of the guide seat 441 is parallel to the radial direction of the central shaft 20. One end of the guide seat 441 is connected to the inner wall of the outer protective layer 10, and the other end thereof is provided with a guide groove 4410, and the extending direction of the guide groove 4410 is parallel to the radial direction of the central shaft 20.

[0055] A sliding portion 45 protrudes from one end of the sliding frame 41 close to the outer protective layer 10. The sliding portion 45 includes a sliding main body portion 414 and two elastic convex portions 415. An air passage 4150 is provided on the elastic convex portion 415. The extending direction of the sliding main body portion 414 is parallel to the radial direction of the central shaft 20, and one end of the sliding main body portion 414 is connected to the surface of the sliding frame 41 on the side away from the central shaft 20. Along the rotation direction of the central shaft 20, the two elastic convex portions 415 are respectively connected to the opposite sides of the sliding main body portion 414. The opening and closing structure 43 includes two opening and closing members 431. Along the rotation direction of the central shaft 20, the two opening and closing members 431 are respectively arranged on the opposite sides of the sliding main body portion 414, and the two opening and closing members 431 can both rotate around the outer peripheral surface of the central shaft 20.

[0056] One end of the sliding main body 414 away from the sliding bracket 41 is slidably received in the guide groove 4410, and 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, and the other end of the first elastic member 442 is elastically connected to one end of the sliding main body 414 away from the sliding bracket 41, so as to provide an elastic force for the sliding main body 414 to move towards the central axis 20.

[0057] In this way, when the abutting portion 411 enters the receiving groove 21 with a smaller groove depth from the receiving groove 21 with a deeper groove depth, the sliding bracket 41 moves towards the side away from the central axis 20, and the sliding main body 414 continuously compresses the first elastic member 442. When the abutting portion 411 enters the receiving groove 21 with a larger groove depth from the receiving groove 21 with a smaller groove depth, the first elastic member 442 resets and applies an elastic force to the sliding main body 414, so as to push the sliding bracket 41 towards the central axis 20 through the sliding main body 414 until the abutting portion 411 abuts tightly against the bottom wall of the receiving groove 21.

[0058] Please also combine with Figures 1 to 5 , in an embodiment, when the sliding bracket 41 is in the first state, the sliding bracket 41 is spaced from the opening and closing member 431, and the first air chamber 434 communicates with the first air hole 412 through the air passage 4150. When the sliding bracket 41 is in the second state, the sliding bracket 41 abuts against the opening and closing member 431, and the opening and closing member 431 closes the first air hole 412. A filter element is filled in the first air chamber 434. 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 chamber 434 to prevent impurities carried in the hot air flow from entering the wire cavity 413 through the first air hole 412 and affecting the operation of the wire core 42.

[0059] 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 respectively arranged on the 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 from the guide seat 441, and the first air chamber 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 protective layer 10, so that the sliding seat 432 can cooperate with the bracket 30 to support the outer protective layer 10, thereby improving the stability and uniformity of the support of the inner layer structure of the network cable in the outer protective layer 10 for the outer protective layer 10.

[0060] The sliding seat 432 is provided with a sliding groove 4320. One end of the opening and closing member 431 is slidably received in the sliding groove 4320, and the other end of the opening and closing member 431 is used to abut against the sliding main body portion 414 or the elastic convex portion 415. Along the radial direction of the central axis 20, the sliding groove 4320 extends from the surface of the sliding seat 432 on the side away from the outer protective layer 10 towards the outer protective layer 10, and along the rotational direction of the central axis 20, the sliding groove 4320 extends from the end face of the sliding seat 432 near the guiding seat 441 towards the side away from the guiding seat 441, so that a first groove wall P1 and a second groove wall P2 are formed in the sliding groove 4320.

[0061] The first groove wall P1 is a curved surface, and its shape is adapted to the shape of the outer protective layer 10. The opening and closing member 431 can slide along the first groove wall P1 to guide the opening and closing member 431 to slide along the rotational direction of the central axis 20 through the first groove wall P1. It can be understood that one of the first groove wall P1 and the surface of the opening and closing member 431 close to the first groove wall P1 may be provided with a sliding protrusion, and the other may be provided with a sliding groove, and the sliding protrusion and the sliding groove are in sliding fit to ensure the sliding of the opening and closing member 431 relative to the first groove wall P1.

[0062] In addition, along the radial direction of the central axis 20, the surface of the opening and closing member 431 close to the central axis 20 and the surface of the sliding seat 432 close to the central axis 20 are coplanar, so as to ensure that when the opening and closing member 431 abuts against the surface of the sliding frame 41 to close the first air hole 412, the sliding seat 432 also abuts against the surface of the sliding frame 41 to ensure that no gap is formed between the two.

[0063] In this embodiment, the opening and closing structure 43 further 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 rotational 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 guiding seat 441, and is used to provide an elastic force for the opening and closing member 431 to move towards the sliding main body portion 414. Thus, when the sliding portion 45 abuts against the two opening and closing members 431 through the elastic convex portion 415 to make them move away from each other, the opening and closing member 431 continuously compresses the second elastic member 433. Subsequently, when the sliding portion 45 no longer abuts against the opening and closing member 431 through the elastic convex portion 415, the second elastic member 433 resets and pushes the opening and closing member 431 to move towards the guiding seat 441 until it abuts against the surface of the guiding seat 441.

[0064] It can be understood that in other embodiments, the opening and closing structure 43 may not be provided with the second elastic member 433. 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 that described above. The opening and closing member 431 is made of compressible silicone or the like, and the sliding seat 432 is provided with a compression groove. A part of the opening and closing member 431 is compressibly received in the compression groove to limit the compression path of the opening and closing member 431 through the compression groove, and one end of the opening and closing member 431 is exposed outside the compression groove and used to abut against the sliding main body portion 414 or the elastic convex portion 415, so as to realize the connection or disconnection of the air path between the first air hole 412 and the first air cavity 434.

[0065] Please also combine with Figures 2 to 6 , in an embodiment, along the rotation direction of the central axis 20, the sliding main body portion 414 is generally located at the middle position of the surface of the sliding frame 41 close to the outer protective layer 10. Along the radial direction of the central axis 20, the air duct 4150 extends through from the side of the elastic convex portion 415 close to the outer protective layer 10 to the side of the elastic convex portion 415 close to the sliding frame 41.

[0066] In this embodiment, the sliding seat 432 is made of an insulating material, the opening and closing member 431 is made of a metal material, and the areas of the sliding frame 41 corresponding to the first air holes 412 are all abutted by the opening and closing member 431 to close the first air holes 412. In addition, based on the fact that the opening and closing member 431 is made of a metal material, when the opening and closing member 431 closes the first air holes 412, it can also play a function of electromagnetic shielding for the space at the first air holes 412 while ensuring the disconnection of the air path, so as to ensure the electromagnetic shielding performance of the sliding frame 41.

[0067] The elastic convex part 415 is made of an elastic material such as rubber, and the cross-sectional shape of the elastic convex part 415 is generally semi-circular. One end of the opening and closing member 431 close to the guiding seat 441 is provided with a sealing part 4310. The sealing part 4310 is made of an elastic material such as rubber, and the cross-sectional shape of the sealing part 4310 is generally an isosceles trapezoid. The sealing part 4310 has a holding surface P3 and two guiding surfaces P4. The holding surface P3 is parallel to the protruding direction of the sliding main body part 414. The holding surface P3 is used to hold the elastic convex part 415 or the surface of the sliding main body part 414. Based on the fact that the sealing part 4310 is made of an elastic material such as rubber, when the holding surface P3 holds against the surface of the sliding main body part 414, a sealing arrangement is provided between the holding surface P3 and the sliding main body part 414 to ensure the sealing performance and electromagnetic shielding performance of the space where the sliding frame 41 is located. Along the protruding direction of the sliding main body part 414, the two guiding surfaces P4 are respectively connected to both ends of the holding surface P3, and the two guiding surfaces P4 are inclined with respect to the holding surface P3. Through the inclined guiding surfaces P4, the elastic convex part 415 can be guided to cross the area where the guiding surfaces P4 are located and push the opening and closing member 431 to move away from the sliding main body part 414, so that the holding surface P3 holds against the elastic convex part 415. In addition, since the sealing part 4310 is made of an elastic material, it is also convenient for the elastic convex part 415 to better cross the sealing part 4310.

[0068] It should be noted that along the protruding direction of the sliding main body part 414, there is enough space between the guiding seat 441 and the opening and closing member 431 to accommodate the elastic convex part 415 that crosses the sealing part 4310, so as to prevent the elastic convex part 415 from holding against the guiding seat 441 and restricting the sliding of the sliding main body part 414.

[0069] 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 part 411 is located in the first receiving groove 211, the sliding frame 41 is in the first state. When the abutting part 411 is located in the second receiving groove 212, the sliding frame 41 is in the second state.

[0070] When the abutting part 411 is located in the first receiving groove 211, the side wall of the sliding frame 41 can simultaneously abut against the support member 51 and the side surface of the first area 31.

[0071] When the abutting part 411 is located in the second receiving groove 212, the first area 31 is spaced apart from the sliding frame 41, and the support member 51 moves under the action of the third elastic member 52 to partially protrude beyond the first area 31, so that the support member 51 continues to abut against the side wall of the sliding frame 41.

[0072] During the process of the abutting portion 411 moving from leaving the first receiving groove 211 to entering the second receiving groove 212, the central axis 20 will gradually push the sliding frame 41 to move radially away from the central axis 20 along the radial direction of the central axis 20. During this process, the gaps between the two side walls of the sliding frame 41 and the adjacent two second zone portions 32 will gradually increase as the sliding frame 41 slides, and the third elastic member 52 in the compressed state will gradually reset, causing the third elastic member 52 to push the support member 51 to move towards the sliding frame 41 and always abut against the side wall of the sliding frame 41 to ensure the stability during the sliding process of the sliding frame 41.

[0073] Further, when the sliding frame 41 is in the first state, the elastic convex portion 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 chamber 435 is formed between the sliding frame 41 and the opening and closing member 431. The first air chamber 434 communicates with the second air chamber 435 through the air passage 4150. The hot air flow enters the second air chamber 435 from the first air chamber 434 through the air passage 4150, and then enters the wire chamber 413 through the first air hole 412.

[0074] When the sliding frame 41 is in the second state, the elastic convex portion 415 is located on the side of the opening and closing member 431 close to the outer protective layer 10, and the abutting surface P3 abuts against the surface of the sliding main body portion 414, so that the opening and closing member 431 and the sliding main body portion 414 are hermetically arranged. In addition, when the sliding frame 41 is in the second state, a partial zone of the sliding seat 432 and the opening and closing member 431 both abut against the surface of the sliding frame 41 to completely cover the surface of the sliding frame 41.

[0075] 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 second receiving groove 212, so that when the abutting portion 411 moves from the first receiving groove 211 to the second receiving groove 212, the abutting portion 411 can move in the transition groove 213, preventing the abutting portion 411 from abutting against the outer peripheral surface of the central axis 20 after leaving the first receiving groove 211 and causing the sliding frame 41 to be too tightly abutted against the opening and closing member 431.

[0076] The groove depth of the transition groove 213 is slightly smaller than the groove depth of the second receiving groove 212 to form a certain slope at the communication portion 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.

[0077] It should be noted that the abutting portion 411 can be made of a material with certain elasticity such as rubber, so that the abutting portion 411 can be slightly squeezed and deformed to cross the slope between the transition groove 213 and the second receiving groove 212 and enter the second receiving groove 212.

[0078] In this embodiment, the bracket 30 is made of a metal material, which has a certain electromagnetic shielding function and can further improve the electromagnetic shielding protection ability of the wire cores 42 located in different sliding brackets 41.

[0079] Further, in other embodiments, each set of receiving grooves 21 may include at least three receiving grooves 21. When the abutting portion 411 is located in one of the three receiving grooves 21, the abutting surface P3 abuts against the elastic protrusion 415 to connect the first air chamber 434 and the second air chamber 435. When the abutting portion 411 is located in the other two of the three receiving grooves 21, the abutting surface P3 abuts against the surface of the sliding main body portion 414 to disconnect the first air chamber 434 from the first air hole 412. By making the groove depths of these two receiving grooves 21 different, the dimensions of the sliding bracket 41 in the radial direction of the central axis 20 can be made different, so as to adapt to different sizes of the sliding brackets 41. In addition, based on the wire core 42 being limited within the sliding bracket 41, different sizes of the sliding brackets 41 are adapted to different sizes of the wire cores 42, so as to achieve adapting to different sizes of the wire cores 42 without changing the size of the outer sheath 10, thereby improving the adaptability of the network cable.

[0080] Please also combine Figure 7 and refer to Figures 1 to 2 In one embodiment, the outer sheath 10 includes a shielding layer 11 and an outer protective sheath 12 arranged in sequence from the inside to the outside. The shielding layer 11 may be a structure with an electromagnetic shielding function such as a metal braided net, and the material of the outer protective sheath 12 may be a material such as vinyl chloride. The shielding layer 11 is a circular ring structure, and a receiving cavity 101 is formed therein. The elastic structure 44 is connected to the inner peripheral surface of the shielding layer 11. The outer protective sheath 12 is arranged around the outer peripheral surface of the shielding layer 11.

[0081] In other embodiments, the outer sheath 10 further includes a water blocking tape, and the water blocking tape may be arranged between the shielding layer 11 and the outer protective sheath 12 to improve the waterproof ability of the outer sheath 10.

[0082] In this embodiment, the network cable 100 with a dehumidifying function further includes two connection ends 60, and the two connection ends 60 are respectively connected to both ends of the outer sheath 10 to close the receiving cavity 101 and the wire cavity 413. In addition, each wire core 42 can be signal-connected to other electronic devices through the two connection ends 60 to achieve signal transmission.

[0083] The connection end 60 is detachably connected to the outer sheath 10, so that when it is necessary to perform dehumidification operation on the network cable 100 with a dehumidifying function, the connection end 60 can be removed to expose the central axis 20, and the network cable 100 with a dehumidifying function can be straightened and the central axis 20 can be rotated to drive the sliding bracket 41 to move.

[0084] Of course, in other embodiments, the network cable 100 with dehumidification function may not include two connection ends 60. That is, at this time, the network cable 100 with dehumidification function is a semi-finished product stored in a warehouse. Before connecting the two connection ends 60, dehumidification operation can be carried out on it first to avoid being affected by moisture during storage and affecting subsequent working performance.

[0085] In other embodiments, a through hole may be opened at the center of the central shaft 20. Along the extension direction of the central shaft 20, the through hole penetrates from the end face of one end of the central shaft 20 to the end face of the other end of the central shaft 20. The through hole can be penetrated by a rotating shaft. Thus, after removing the connection end 60, the rotating shaft is penetrated through the through hole, and the central shaft 20 is driven to rotate by the rotating shaft. For example, a compression spring is provided on the outer peripheral surface of the rotating shaft. One end of the compression spring is connected to the rotating shaft, and the other end is connected to a suction cup. After compressing the compression spring, the suction cup is placed into the through hole together. Subsequently, the compression spring resets and the suction cup adsorbs on the inner wall of the central shaft 20, so that the central shaft 20 and the rotating shaft are relatively fixed, and then the central shaft 20 is driven to rotate by the rotating shaft.

[0086] In the above text, the specific embodiments of the present application are described with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that various changes and substitutions can be made to the specific embodiments of the present application without departing from the scope of the present application. These changes and substitutions all fall within the scope defined by the present application.
