Based on the elastic deformation of the elastic structure, the air duct can be opened or closed.

[0005] In a possible implementation manner, a plurality of groups of accommodation grooves are formed on the outer peripheral surface of the central axis, and the plurality of groups of accommodation grooves are correspondingly arranged with the plurality of sliding components.

Along the rotation direction of the central axis, the plurality of accommodation grooves are arranged at intervals, and the groove depths of the plurality of accommodation grooves increase linearly.

[0006] In a possible implementation manner, the elastic structure includes a main body member and a plurality of first elastic members. One side of the main body member is connected to the inner wall of the outer protective layer, and the plurality of first elastic members protrude from the side of the main body member far from the outer protective layer. The first elastic members elastically abut against the sliding frame. Along the rotation direction of the central axis, the plurality of first elastic members are arranged at intervals, and an air duct is formed between any two adjacent first elastic members.

[0007] In a possible implementation, the network cable with dehumidification function further includes a plurality of brackets. The plurality of brackets are arranged at equal intervals around the outer peripheral surface of the central axis. An activity cavity is formed between any two adjacent brackets, and a sliding component is arranged in each activity cavity; the extending direction of the bracket is parallel to the radial direction of the central axis, and one end of the bracket is connected to the inner wall of the outer protective layer.

In addition, when the sliding frame slides radially along the central axis, the sliding frame can abut against the elastic structure to cause it to undergo elastic deformation, realizing the opening or closing of the air passage. When it is necessary to dehumidify the network cable, the central axis is rotated to open the air passage, and hot air flow is injected into the air passage from the outside, so as to dehumidify the internal space of the network cable and ensure the normal operation of the network cable. After the dehumidification is completed, the central axis is rotated again to close the air passage, thereby ensuring the sealing performance of the network cable and preventing water vapor from entering the sliding frame and affecting the normal operation of the wire core.

[0024] The following specifically describes the embodiments of the present application in further detail with reference to the accompanying drawings.

[0025] As Figures 1 to 2 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 sliding assembly 40.

[0026] The outer sheath 10 is provided with a receiving cavity 101 therein, and the central shaft 20 is rotatably disposed in the receiving cavity 101 and coaxially arranged with the outer sheath 10. A plurality of brackets 30 are arranged at equal intervals around the outer peripheral surface of the central shaft 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 shaft 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 a plurality, and one sliding assembly 40 is provided in each activity 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 disposed in the activity cavity 33, a wire cavity 413 is formed in the sliding frame 41, and the wire core 42 is disposed in the wire cavity 413. The elastic structure 43 is clamped between the sliding frame 41 and the outer sheath 10 and connected to the outer sheath 10. An air passage 430 is provided on the elastic structure 43, and a micropore 412 is formed at one end of the sliding frame 41 close to the elastic structure 43. The micropore 412 communicates the air passage 430 and the activity cavity 33. When the central shaft 20 rotates, the central shaft 20 can abut against the sliding frame 41 to move along the radial direction of the central shaft 20, so that the elastic structure 43 undergoes elastic deformation. Based on the elastic deformation of the elastic structure 43, the air passage 430 can be opened or closed.

[0027] Thus, in the network cable 100 with a dehumidification function of the present application, the rotation of the central shaft 20 drives the sliding frame 41 to slide along the radial direction of the central shaft 20 in the activity cavity 33, so that the outer diameter of the inner sheath formed by the plurality of sliding assemblies 40 can be adjusted to adapt to different usage requirements. In addition, when the sliding frame 41 slides along the radial direction of the central shaft 20, the sliding frame 41 can abut against the elastic structure 43 to cause it to undergo elastic deformation, realizing the opening or closing of the air passage 430. When dehumidifying the network cable is required, the central shaft 20 is rotated to open the air passage 430, and hot air flow is injected into the air passage 430 from the outside, thereby performing dehumidification operation on the internal space of the network cable to ensure that the network cable can work normally. After the dehumidification is completed, the central shaft 20 is rotated again to close the air passage 430, thereby ensuring the sealing performance of the network cable and preventing water vapor from entering the sliding frame 41 and affecting the normal operation of the wire core 42.

[0028] Please also combine with Figures 1 to 2 In an embodiment, the central shaft 20 is a cylindrical structure, and the extending direction of the central shaft 20 is parallel to the extending direction of the network cable. A plurality of receiving grooves 21 are formed on the outer peripheral surface of the central shaft 20, and the plurality of receiving grooves 21 are correspondingly arranged with the plurality of sliding assemblies 40. Along the radial direction of the central shaft 20, a abutting portion 411 protrudes from one end of each sliding frame 41 close to the central shaft 20, and the abutting portion 411 is approximately located at the middle position of one end of the sliding frame 41 close to the central shaft 20.

[0029] Each set of receiving grooves 21 includes a plurality of receiving grooves 21. The receiving grooves 21 are used to receive the abutting portions 411. Along the rotation direction of the central axis 20, the respective receiving grooves 21 of each set are arranged at intervals. The central axis 20 is made of a material such as rubber to ensure that the central axis 20 can be bent along with the network cable, and the central axis 20 has a certain structural strength to ensure that the groove walls of the receiving grooves 21 of the central axis 20 can abut against the abutting portions 411 and then apply a force to the abutting portions 411 to push the sliding frame 41 to move.

[0030] 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 portions 411 is set to four, and the included angle between any two adjacent abutting portions 411 is also 90°.

[0031] 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 the actual design requirements.

[0032] Along the radial direction of the central axis 20, the receiving grooves 21 are formed by recessing inward from the outer peripheral surface of the central axis 20. The receiving grooves 21 are used to receive the abutting portions 411, and the abutting portions 411 can abut against the bottom wall of the receiving grooves 21, so as to clamp the sliding frame 41 between the elastic structure 43 and the central axis 20 to realize the radial limit of the sliding frame 41. Along the rotation direction of the central axis 20, the respective receiving grooves 21 of the same set are arranged at intervals, and the groove depths of the respective receiving grooves 21 increase linearly. The groove depths of the respective receiving grooves 21 are different, so that when the abutting portions 411 are 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 43 abutted by the sliding frame 41 can undergo different degrees of elastic deformation.

[0033] In this embodiment, the cross-sectional shape of the abutting portion 411 is generally semi-circular, and the shape of the receiving groove 21 is adapted to the shape of the abutting portion 411 to ensure the stability of the limit of the sliding frame 41 when the abutting portion 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 portion 411 is semi-circular, and the shape of the receiving groove 21 is adapted to the shape of the abutting portion 411 to guide the abutting portion 411 in and out of the receiving groove 21 through a curved surface, so as to ensure that the abutting portion 411 can easily disengage from the receiving groove 21.

[0034] 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 to ensure that when the central axis 20 rotates to make the abutting portion 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.

[0035] Radially along the central axis 20, the shape of the end face of the end of the sliding frame 41 away from the central axis 20 is adapted to the shape of the inner peripheral surface of the outer sheath 10, and a plurality of micropores 412 are equidistantly formed in the end face of the end of the sliding frame 41 away from the central axis 20.

[0036] The wire 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. Radially along the central axis 20, the opposite sides of the wire core 42 respectively abut against the inner walls of the opposite sides of the sliding frame 41 to realize the radial limit of the wire core 42 with respect to the central axis 20. In addition, the sliding frame 41 is also filled with a filler, which can be a filling rope or the like. Along the rotation direction of the central axis 20, the filler fills the space between the wire core 42 and the inner walls of the opposite sides of the sliding frame 41 to realize the limit of the wire core 42 in the rotation direction of the central axis 20, so as to ensure that the wire core 42 does not shake or the like in the sliding frame 41.

[0037] Please also combine with Figures 1 to 2 , in an embodiment, the elastic structure 43 includes a main body member 431 and a plurality of first elastic members 432. The main body member 431 is generally an arc-shaped structure, and the main body member 431 is made of an insulating material with a certain elasticity such as rubber, so that the main body member 431 can be bent to a certain extent along with the network cable. In addition, the main body member 431 made of an insulating material can play a role in leakage protection when contacting the sliding frame 41 made of a metal material.

[0038] Along the rotation direction of the central axis 20, the two ends of the main body member 431 respectively abut tightly against two adjacent brackets 30. And based on the fact that the main body member 431 is made of an elastic material, a sealing structure is formed by the close contact between the end of the main body member 431 and the bracket 30, so as to prevent the water vapor accumulated at the outer sheath 10 from flowing into the movable cavity 33 along the bracket 30 from the gap between the main body member 431 and the bracket 30, thereby improving the waterproof property of the wire core 42. Radially along the central axis 20, one side of the main body member 431 is attached to and connected to the inner wall of the outer sheath 10, and a plurality of compression grooves 4310 are formed on the other side of the main body member 431.

[0039] A plurality of compression grooves 4310 are arranged corresponding to a plurality of first elastic members 432, and one 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 body member 431, and the other end thereof is elastically connected to the sliding frame 41, so as to apply an elastic force to the sliding frame 41 through the first elastic member 432. Based on the fact that the main body member 431 is made of an elastic material, when the main body member 431 applies a force to the first elastic member 432 and receives its reaction force, the main body member 431 itself can undergo a certain degree of elastic deformation to offset the reaction force, thereby avoiding the phenomenon that the main body member 431 squeezes the outer protective layer 10 and causes local bulging. At the same time, the main body member 431 made of an elastic material in cooperation with the first elastic member 432 can provide radial buffering for the network cable, so that when the network cable is externally squeezed, the external force can be offset by the elastic deformation of the main body member 431 and the first elastic member 432, thereby improving the compressive capacity of the network cable.

[0040] Along the rotation direction of the central axis 20, the plurality of first elastic members 432 are arranged at intervals, and an air passage 430 is formed between any two adjacent first elastic members 432. Along the rotation direction of the central axis 20, the plurality of first elastic members 432 and the plurality of micropores 412 are alternately arranged at intervals, so that each air passage 430 can communicate with a micropore 412.

[0041] The first elastic member 432 elastically abuts against the end face of the end of the sliding frame 41 away from the central axis 20. During the sliding process of the sliding frame 41, the first elastic member 432 is compressed toward the side of the main body member 431 by the sliding frame 41 pressing against it, so that the size of the air passage 430 gradually decreases until the end face of the end of the sliding frame 41 away from the central axis 20 contacts the surface of the side of the main body member 431 away from the outer protective layer 10 (that is, the first elastic member 432 is compressed to be completely located in the compression groove 4310), the air passage 430 is closed, and the micropore 412 is closed by the surface of the side of the main body member 431 away from the outer protective layer 10, thereby improving the sealing performance of the sliding frame 41. On the one hand, it avoids electromagnetic interference from the external environment of the sliding frame 41 to the wire core 42 inside the sliding frame 41, and on the other hand, it avoids water vapor and the like that may penetrate into the outer protective layer 10 from entering the sliding frame 41 through the micropores 412 and affecting the performance of the wire core 42.

[0042] It can be understood that in other embodiments, the elastic structure 43 can also adopt other structures, as long as it can undergo elastic deformation, and based on this elastic deformation, the air passage 430 can be opened or closed. In addition, in addition to the first elastic member 432 being a compression spring as described above, the first elastic member 432 can also be a fitting made of an elastic material such as compressible silica gel. For example, the elastic structure 43 includes a main body member 431, and the main body member 431 is made of an elastic material such as compressible silica gel. At this time, the first elastic member 432 and the main body member 431 are integrally formed, and the materials of the two are the same. A plurality of grooves are provided at intervals on the side of the main body member 431 away from the outer protective layer 10, and an air passage 430 is formed at the grooves for air flow, and a protrusion is formed between any two adjacent grooves, and this protrusion is the first elastic member 432. During the sliding process of the sliding frame 41, the sliding frame 41 presses against the protrusion of the main body member 431, so that the protrusion is compressed, and the protrusion undergoes circumferential deformation, so that the size of the air passage 430 gradually decreases until it is closed.

[0043] In addition, considering that the protrusion undergoes circumferential deformation, there may be a certain thickness, resulting in a certain gap between the main body member 431 and the sliding frame 41. In some embodiments, a blocking protrusion may protrude from the bottom wall of the groove, and the protruding length of the blocking protrusion is less than the length of the protrusion in the natural state. And when the protrusion is compressed to a certain extent, the sliding frame 41 can abut against the blocking protrusion, so as to close the air passage 430 through the blocking protrusion.

[0044] In this embodiment, the pore diameter of the micropores 412 is 50 nm to 100 nm, so as to ensure that the hot air can enter the inner space of the sliding frame 41 from the micropores 412 for dehumidification operation, and at the same time, a micropore 412 shielding can be formed on the end face of the sliding frame 41 near the outer protective layer 10 by using a plurality of micropores 412 with smaller pore diameters, thereby further improving the electromagnetic interference resistance of the wire core 42 located in the sliding frame 41. In addition, the sliding frame 41 is made of a metal material to further improve the electromagnetic interference resistance of the wire core 42 located in the sliding frame 41.

[0045] It can be understood that the pore diameter of the micropores 412 can be 50 nm, 60 nm, 70 nm, 80 nm, 90 nm, 100 nm, etc.

[0046] Please also combine Figures 1 to 2 In an 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, and the other end of the second section 32 abuts against the outer peripheral surface of the central axis 20, so as to abut against the central axis 20 along the radial direction of the central axis 20 through the second sections 32 of a plurality of brackets 30, thereby ensuring the stability of the central axis 20 during rotation.

[0047] It can be understood that in other embodiments, one end of the second section 32 away from the first section 31 may also be spaced from the outer peripheral surface of the central axis 20. At this time, the sliding frame 41 can play a guiding role in the rotation of the central axis 20 to ensure the stability of its rotation.

[0048] The first section 31 is clamped between two adjacent elastic structures 43, and the first section 31 is connected to the two adjacent elastic structures 43. The second section 32 can abut against the side wall of the sliding frame 41 to clamp the sliding frame 41 located between the two second sections 32 in the rotation direction of the central axis 20, thereby ensuring the stability of the sliding frame 41.

[0049] In this embodiment, along the rotation direction of the central axis 20, receiving grooves 320 are respectively provided on the opposite sides of the second section 32, and the receiving grooves 320 communicate with the movable cavity 33. A second elastic member 50 is provided in the receiving groove 320, and the second elastic member 50 is elastically compressed between the groove wall of the receiving groove 320 and the sliding frame 41.

[0050] 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.

[0051] When the abutting portion 411 is located in the first receiving groove 211, a part of the first elastic member 432 is located outside the compression groove 4310 and abuts against the sliding frame 41, and the main body member 431 is spaced from the sliding frame 41, so that the air passage 430 communicates with the micropores 412, so that the hot air flow can enter the wire cavity 413 from the air passage 430 and the micropores 412 to dehumidify the wire core 42. In addition, when the abutting portion 411 is located in the first receiving groove 211, the second 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.

[0052] 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 to make the main body member 431 abut against the sliding frame 41, so that the main body member 431 closes the micropores 412. In addition, when the abutting portion 411 is located in the second receiving groove 212, the second section 32 is spaced from the sliding frame 41, and a part of the second elastic member 50 is exposed outside the receiving groove 320 and elastically abuts against the sliding frame 41.

[0053] During the process in which the abutting portion 411 moves from leaving the first receiving groove 211 to entering the second receiving groove 212, the central axis 20 will gradually push the sliding bracket 41 to move radially away from the central axis 20 along the central axis 20. During this process, gaps will be formed between the two side walls of the sliding bracket 41 and the adjacent two second zone portions 32, and the gaps will gradually increase as the sliding bracket 41 slides. The second elastic member 50 that is elastically compressed in the receiving groove 320 starts to reset, so that a part of the second elastic member 50 leaves the receiving groove 320 and abuts against the side wall of the sliding bracket 41 to ensure the stability during the sliding process of the sliding bracket 41. In addition, when the abutting portion 411 is located in the second receiving groove 212, the second elastic member 50 fills the gap between the sliding bracket 41 and the second zone portion 32, thereby ensuring the stability of the sliding bracket 41 after the position adjustment is completed.

[0054] Further in combination with 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 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 to prevent the abutting portion 411 from abutting against the outer peripheral surface of the central axis 20 after leaving the first receiving groove 211, which may cause the sliding bracket 41 to be too tightly abutted against the main body member 431.

[0055] 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 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.

[0056] It should be noted that the abutting portion 411 can be made of a material with a 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.

[0057] 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. The second elastic member 50 is made of an elastic material with a certain water absorption performance, such as sponge and other materials. While providing elastic support for the sliding bracket 41 through the second elastic member 50, the second elastic member 50 can also absorb the water leaking or accumulating along the surface of the sliding bracket 41, further improving the radial water blocking ability of the network cable.

[0058] 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, there is a gap between the main body member 431 and the sliding frame 41, so that the air passage 430 is opened. When the abutting portion 411 is located in the other two of the three receiving grooves 21, the main body member 431 abuts against the sliding frame 41 to close the air passage 430. By making the groove depths of these two receiving grooves 21 different, the dimensions of the sliding frame 41 in the radial direction of the central axis 20 can be made different, so as to adapt to sliding frames 41 of different sizes. In addition, based on the fact that the wire core 42 is limited within the sliding frame 41, sliding frames 41 of different sizes are adapted to wire cores 42 of different sizes, so as to achieve the adaptation of wire cores 42 of different sizes under the condition that the size of the outer sheath 10 remains unchanged, thereby improving the adaptability of the network cable.

[0059] Please refer to Figures 1 to 4 In one embodiment, the outer sheath 10 includes a shielding layer 11 and an outer sheath 12 arranged in sequence from the inside out. The shielding layer 11 may be a structure with electromagnetic shielding function such as a metal braided net, and the material of the outer 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 43 is connected to the inner peripheral surface of the shielding layer 11. The outer sheath 12 is arranged around the outer peripheral surface of the shielding layer 11.

[0060] 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 sheath 12 to improve the waterproof ability of the outer sheath 10.

[0061] In this embodiment, the network cable 100 with dehumidification 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.

[0062] 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 dehumidification function, the connection end 60 can be removed to expose the central axis 20, and the network cable 100 with dehumidification function can be straightened and the central axis 20 can be rotated to drive the sliding frame 41 to move.

[0063] 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 the warehouse. Before connecting the two connection ends 60, dehumidification operation can be performed on it first to avoid moisture absorption during storage and affect subsequent working performance.

[0064] In other embodiments, a through hole may be formed at the center of the central shaft 20. Along the extending direction of the central shaft 20, the through hole extends through from the end face at one end of the central shaft 20 to the end face at the other end of the central shaft 20. The through hole can be penetrated by a rotating shaft. Thus, after the connecting end portion 60 is removed, 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 thereof is connected to a suction cup. After the compression spring is compressed, the suction cup is placed into the through hole together with the compression spring. Subsequently, the compression spring resets to enable the suction cup to adsorb 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.

[0065] In the foregoing, the specific embodiments of the present application have been 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.
