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

[0035] As shown in Figures 1 to 4, this embodiment provides a low-voltage cabinet 100 with cable-assisted plug-in function, including a first cabinet 10, a second cabinet 20, multiple plug-in components 30, a sliding component 40, and an adjusting component 50.

[0036] For ease of reading, this application introduces a first direction Y, a second direction Z, and a third direction X to describe the embodiments of this application. The first direction Y, the second direction Z, and the third direction X can be three non-parallel straight lines in space; further, the first direction Y, the second direction Z, and the third direction X can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction Y is described as the Y-axis direction of the three-dimensional coordinate system, the second direction Z is the Z-axis direction of the three-dimensional coordinate system, and the third direction X is the X-axis direction of the three-dimensional coordinate system.

[0037] The first cabinet 10 contains electrical components. Along the first direction Y, the second cabinet 20 is connected to one side of the first cabinet 10. The side of the first cabinet 10 away from the second cabinet 20 has multiple pull-out cavities 11. Each pull-out cavity 11 can be slidably provided with a drawer unit 12. The drawer unit 12 can be pulled out or inserted into the pull-out cavity 11 along the first direction Y. The electrical components are placed inside the drawer unit 12.

[0038] The second cabinet 20 contains cables. The first cabinet 10 has multiple interface terminals 22 located on the side near the second cabinet 20, arranged in a rectangular array. Multiple cables are also present, each corresponding to one of the interface terminals 22. Each cable can be inserted into its corresponding interface terminal 22 along the first direction Y, and the interface terminal 22 is electrically connected to electrical components, enabling the transmission of electrical or control signals between the cables and the electrical components.

[0039] The second cabinet 20 has an internal cavity 21, within which multiple sets of plug-in components 30 are disposed. Multiple interface terminals 22 are located on the inner wall of the cavity 21 near the first cabinet 10. Along the second direction Z, the multiple sets of plug-in components 30 are spaced apart, and each set includes multiple plug-in components 30. Along the third direction X, multiple plug-in components 30 within the same set are spaced apart, and each plug-in component 30 corresponds to a cable, enabling the plugging and unplugging of the cable with the interface terminal 22.

[0040] The plug-in / plug-out assembly 30 includes a first sliding structure 31, a lifting structure 32, and a clamping structure 33. The first sliding structure 31 is driven to the lifting structure 32 and is used to drive the lifting structure 32 to slide along a first direction Y, so as to realize the plugging and unplugging of the cable along the first direction Y through the first sliding structure 31. The clamping structure 33 includes a fixed clamping plate 332 and a movable clamping plate 331. The fixed clamping plate 332 is driven to the first sliding structure 31 so that the fixed clamping plate 332 can slide along the first direction Y with the lifting structure 32. Along a third direction X, the movable clamping plate 331 is disposed on one side of the fixed clamping plate 332. The lifting structure 32 is driven to the movable clamping plate 331 and is used to drive the movable clamping plate 331 to move up and down along a second direction Z, and the movable clamping plate 331 can slide along the first direction Y with the lifting structure 32. Thus, both the movable clamping plate 331 and the fixed clamping plate 332 can slide along the first direction Y, so that after the movable clamping plate 331 and the fixed clamping plate 332 clamp the cable, they can move along the first direction Y to drive the cable to move and realize the insertion and removal of the cable.

[0041] A sliding assembly 40 is disposed within the inner cavity 21. The sliding assembly 40 includes a second sliding structure 41, a third sliding structure 42, and multiple sliding boxes 43. The third sliding structure 42 is drively connected to the second sliding structure 41 and is used to drive the second sliding structure 41 to move up and down along the second direction Z, so as to cooperate with different groups of plug-in assemblies 30. Multiple sliding boxes 43 are spaced apart along the third direction X. The distance between any two adjacent plug-in assemblies 30 in the same group is greater than the width of the sliding box 43 along the third direction X, so that the sliding box 43 can smoothly slide from between two adjacent plug-in assemblies 30 along the second direction Z to another group of plug-in assemblies 30.

[0042] Multiple sliding boxes 43 are correspondingly arranged with multiple plug-in components 30 of any set of plug-in components 30. The second sliding structure 41 is connected to the multiple sliding boxes 43 for driving the multiple sliding boxes 43 to slide synchronously along the third direction X. Along the second direction Z, the top of the sliding box 43 has a mounting cavity 430, and the movable clamping plate 331 can at least partially extend into the mounting cavity 430. The adjustment component 50 is disposed in the mounting cavity 430, and the adjustment component 50 includes an adjustment structure 51 and a supporting plate 52. Along the third direction X, the movable clamping plate 331 can slide relative to the lifting structure 32. The supporting plate 52 is used to support the movable clamping plate 331 to drive the movable clamping plate 331 to slide along the third direction X. When the second sliding structure 41 drives the sliding box 43 to slide along the third direction X, the sliding box 43 pushes the movable clamping plate 331 to slide along the third direction X by supporting the movable clamping plate 331 through the supporting plate 52, thereby realizing that the movable clamping plate 331 moves closer to the fixed clamping plate 332.

[0043] The adjusting structure 51 is connected to the support plate 52 for driving the support plate 52 to slide along the third direction X, so as to adjust the distance between the support plate 52 and the moving clamp 331 along the third direction X, so that each sliding box 43 needs to move a different distance during the synchronous sliding process to make the support plate 52 abut against the moving clamp 331, thereby enabling each plug-in assembly 30 in the same group of plug-in assemblies 30 to plug in cables of different outer diameters.

[0044] Thus, the low-voltage cabinet 100 with cable-assisted plug-in function of this application drives the second sliding structure 41 to slide along the second direction Z through the third sliding structure 42, so that multiple sets of plug-in components 30 can share one set of sliding components 40 as a power source to move the moving clamp 331 closer to or further away from the fixed clamp 332 along the third direction X. In addition, multiple sliding boxes 43 are all driven by the same second sliding structure 41 to move the moving clamp 331 closer to or further away from the fixed clamp 332 along the third direction X, which greatly reduces the structural complexity of the entire low-voltage cabinet and reduces manufacturing costs. At the same time, the lifting structure 32 can not only drive the moving clamp 331 to move closer to the positioning plate along the second direction Z to press the cable, but also allow the moving clamp 331 to partially extend into the sliding box 43 and move with the sliding box 43 along the third direction X. Furthermore, the adjustment component 50 provided inside the sliding box 43 can adjust the distance between each supporting plate 52 and the moving clamping plate 331 by adjusting the working state of the adjustment structure 51 inside each sliding box 43, so that each clamping structure 33 can clamp cables with different outer diameters.

[0045] Referring again to Figures 1 to 4, in one embodiment, the first sliding structure 31 includes a first lead screw 311 and a first sliding sleeve 312. The first lead screw 311 is disposed along a first direction Y, and the first sliding sleeve 312 is sleeved on the outer peripheral surface of the first lead screw 311 and threadedly engaged with the first lead screw 311. The first lead screw 311 is used to drive the first sliding sleeve 312 to slide along the first direction Y.

[0046] The lifting structure 32 includes a lifting drive component 321 and a lifting plate 322. The lifting drive component 321 is a cylinder, which is connected to the bottom end of the first sliding sleeve 312 via a cylinder mounting plate, so that the lifting drive component 321 slides with the first sliding sleeve 312 in the first direction Y. The lifting plate 322 is located at the bottom end of the lifting drive component 321, and the lifting drive component 321 is throttle-connected to the lifting plate 322, for driving the lifting plate 322 to move up and down in the second direction Z.

[0047] In this embodiment, the fixed clamping plate 332 is connected to the first sliding sleeve 312. Along the third direction X, a connecting rod 35 is connected to the right side of the first sliding sleeve 312. The connecting rod 35 is approximately "L" shaped, and the end of the connecting rod 35 away from the first sliding sleeve 312 is connected to the fixed clamping plate 332.

[0048] Along the third direction X, the movable clamp 331 is slidably connected to the lifting plate 322 to ensure that the movable clamp 331 can slide relative to the lifting plate 322 along the third direction X with the sliding box 43. The movable clamp 331 is used to approach the fixed clamp 332 along the second direction Z and / or the third direction X to clamp the cable.

[0049] The movable clamp 331 moves closer to the fixed clamp 332 along the third direction X to clamp the cable in the third direction X. The movable clamp 331 moves closer to the fixed clamp 332 along the second direction Z to press the cable firmly in the second direction Z, preventing the cable from lifting after being clamped in the third direction X, and ensuring the accuracy of subsequent cable insertion and removal.

[0050] In this embodiment, both the fixed clamping plate 332 and the movable clamping plate 331 are L-shaped.

[0051] The fixed clamp 332 includes a first fixed section 3321 and a second fixed section 3322, both of which are flat plate structures. The first fixed section 3321 is disposed along a second direction Z, and the second fixed section 3322 is disposed along a third direction X. The second fixed section 3322 is connected to the bottom end of the first fixed section 3321 on the side along the third direction X near the movable clamp 331, and is used to place cables.

[0052] The movable clamp 331 includes a first movable section 3311 and a second movable section 3312, both of which are flat plate structures. The first movable section 3311 is disposed along a second direction Z, and the second movable section 3312 is disposed along a third direction X, with the second movable section 3312 connected to the top end of the first movable section 3311 on the side along the third direction X near the fixed clamp 332. Along the second direction Z, the second movable section 3312 is spaced above the second fixed section 3322, so that the cable can be clamped between the second movable section 3312 and the second fixed section 3322.

[0053] It is worth noting that the fixed clamp 332 serves to position the cable to ensure that the cable can be accurately inserted into the interface end 22. When the first moving part 3311 presses the cable against the first fixed part 3321 in the third direction X, and the second moving part 3312 presses the cable against the second fixed part 3322 in the second direction Z, the first fixed part 3321 and the second fixed part 3322 limit the cable in the second direction Z and the third direction X, ensuring that the cable clamped by the passive clamp 331 and the fixed clamp 332 can be accurately inserted into the interface end 22.

[0054] Referring again to Figures 2 to 5, in one embodiment, the clamping structure 33 further includes a mounting plate 34, which is disposed on the side of the lifting plate 322 away from the lifting drive member 321. A sliding protrusion 341 protrudes from the side of the mounting plate 34 near the lifting plate 322, and a sliding groove 3220 is provided along the third direction X on the side of the lifting plate 322 near the mounting plate 34. The sliding protrusion 341 is slidably disposed within the sliding groove 3220, so that the mounting plate 34 can slide relative to the lifting plate 322 along the third direction X.

[0055] The movable clamping plate 331 is connected to the side of the mounting plate 34 away from the lifting plate 322. A connecting rod 36 is provided between the movable clamping plate 331 and the mounting plate 34, and the connecting rod 36 is approximately "L" shaped. One end of the connecting rod 36 is connected to the mounting plate 34, and the other end is connected to the first movable area 3311. A supporting protrusion 342 is provided on the side of the mounting plate 34 away from the lifting plate 322. Along the first direction Y, the supporting protrusions 342 are spaced apart on the side of the connecting rod 36 away from the first cabinet 10. The supporting protrusions 342 are flat and are arranged along the first direction Y. The supporting protrusions 342 are used to support the supporting plate 52 along the third direction X. The supporting plate 52 pushes the mounting plate 34 to slide to the right along the third direction X by supporting the supporting protrusions 342, thereby driving the movable clamping plate 331 to move closer to the fixed clamping plate 332 along the third direction X.

[0056] Specifically, the length of the sliding box 43 along the first direction Y should be large enough so that when the moving clamp 331 and the fixed clamp 332 clamp the cable for insertion along the first direction Y, the abutting protrusion 342 is always located in the mounting cavity 430 and is in a state of being pressed by the abutting plate 52, thus ensuring the stability of the cable clamping.

[0057] It is worth noting that when the cable needs to be released, the sliding box 43 moves to the left along the third direction X, and the mounting cavity 430 pushes the mounting plate 34 to slide to the left along the third direction X after abutting the protrusion 342 along the right inner wall of the third direction X, thereby driving the moving clamp 331 away from the fixed clamp 332 along the third direction X, thus releasing the cable.

[0058] Furthermore, along the first direction Y, the sliding box 43 is always located at intervals on the side away from the first cabinet 10 from the moving clamp 331 and the fixed clamp 332, and the distance between the mounting plates 34 of two adjacent plug-in components 30 is greater than the width of the sliding box 43 along the third direction X, ensuring that the sliding box 43 can slide from the space between two adjacent mounting plates 34 along the second direction Z and be used in conjunction with different sets of plug-in components 30.

[0059] In this embodiment, the adjustment structure 51 is an electromagnetic spring. The electromagnetic spring is located on the inner wall of the left side of the mounting cavity 430 along the third direction X, and the electromagnetic spring is arranged along the third direction X. The abutment plate 52 is connected to the electromagnetic spring. After the electromagnetic spring is energized, it can drive the abutment plate 52 to move back and forth along the third direction X. The electromagnetic spring is configured to adjust the moving distance of the abutment plate 52 along the third direction X based on the magnitude of the current it is connected to. This allows each sliding box 43 to move different distances when moving synchronously before it can start pushing the moving clamp 331 closer to the fixed clamp 332. Thus, when each sliding box 43 stops moving, each sliding box 43 pushes its corresponding moving clamp 331 to press the cable against the fixed clamp 332, thereby achieving synchronous clamping of the cable.

[0060] In this embodiment, a connecting plate 23 protrudes from the inner wall of the inner cavity 21 on the side near the first cabinet 10. The connecting plate 23 extends along the first direction Y, and a mounting portion 230 protrudes downward from the bottom surface of the end of the connecting plate 23 away from the first cabinet 10 along the second direction Z. One end of the first lead screw 311 is rotatably connected to the inner wall of the inner cavity 21 on the side near the first cabinet 10, and the other end of the first lead screw 311 is rotatably connected to the mounting portion 230.

[0061] Specifically, the number of connecting plates 23 is the same as the number of first lead screws 311, and each first lead screw 311 is mounted via a connecting plate 23. Along the third direction X, the outer contour of the connecting plate 23 does not exceed the mounting plate 34, so as to avoid the setting of the connecting plate 23 affecting the sliding of the sliding box 43 along the second direction Z.

[0062] Referring again to Figures 2 to 6, in one embodiment, the second sliding structure 41 includes a second lead screw 411 and a second sliding sleeve 412. The second lead screw 411 is disposed along a third direction X and is rotatably connected to the third sliding structure 42. The second sliding sleeve 412 is sleeved on the outer peripheral surface of the second lead screw 411, and the second sliding sleeve 412 is threadedly engaged with the second lead screw 411. The second lead screw 411 is used to drive the second sliding sleeve 412 to slide along the third direction X. Each sliding box 43 is connected to at least one second sliding sleeve 412 so that the sliding box 43 can slide back and forth along the third direction X via the second sliding sleeve 412.

[0063] Along the first direction Y, the mounting part 230 is spaced apart on the side of the second lead screw 411 near the first cabinet 10, so as to avoid the second lead screw 411 being obstructed by the mounting part 230, the connecting plate 23, and the first lead screw 311 when it moves along the second direction Z by utilizing the spatial misalignment design.

[0064] In this embodiment, the number of third sliding structures 42 is set to two, and along the third direction X, the two third sliding structures 42 are respectively disposed on the two opposite inner walls of the inner cavity 21.

[0065] The third sliding structure 42 includes a third lead screw 421, a third sliding sleeve 422, and a sliding plate 423. The third lead screw 421 is arranged along the second direction Z, and its two ends are rotatably connected to two opposite inner walls of the inner cavity 21 along the second direction Z. The third sliding sleeve 422 is sleeved on the outer circumferential surface of the third lead screw 421, and the third sliding sleeve 422 is threadedly engaged with the third lead screw 421. The third lead screw 421 is used to drive the third sliding sleeve 422 to slide along the second direction Z. The sliding plate 423 is connected to the third sliding sleeve 422, and the two ends of the second lead screw 411 are rotatably connected to the two sliding plates 423. The second lead screw 411 is driven by a motor to drive the second lead screw 411 to rotate. The motor is mounted on the sliding plate 423.

[0066] It is understood that, in another embodiment, the second lead screw 411 may also extend through the sliding plate 423 and the inner cavity 21 and be exposed outside the second cabinet 20, thereby enabling manual control of the rotation of the second lead screw 411. The outer wall of the second cabinet 20 is provided with a strip-shaped hole along the second direction Z, so that the end of the second lead screw 411 extending out of the second cabinet 20 can slide within the strip-shaped hole along the second direction Z.

[0067] Furthermore, the third sliding structure 42 also includes a synchronous pulley 4210, which is coaxially connected to the third lead screw 421 and is located near the top wall of the inner cavity 21. The synchronous pulleys 4210 of the two third sliding structures 42 are connected by a synchronous belt 4211 to achieve synchronous rotation of the two synchronous pulleys 4210, thereby achieving synchronous rotation of the two third lead screws 421.

[0068] In some embodiments, the third lead screw 421 of a third sliding structure 42 protrudes through the top wall of the inner cavity 21 and is exposed outside the second cabinet 20. A handwheel can be installed at the end of the third lead screw 421 exposed outside the second cabinet 20 to drive the third lead screw 421 to rotate, thereby achieving manual drive.

[0069] In other embodiments, a third lead screw 421 of a third sliding structure 42 protrudes through the top wall of the inner cavity 21 and is exposed in the second cabinet 20. The end of the third lead screw 421 exposed in the second cabinet 20 is connected to a motor so as to drive the third lead screw 421 to rotate.

[0070] Referring again to Figure 5 and Figure 2, in one embodiment, the low-voltage cabinet 100 with cable-assisted plug-in function further includes multiple power components 60. The multiple power components 60 are correspondingly arranged with multiple sets of plug-in components 30, and each power component 60 drives the first lead screw 311 of each plug-in component 30 in the corresponding set of plug-in components 30 to rotate synchronously.

[0071] Specifically, the power assembly 60 includes multiple drive wheels 61, a drive belt 62, and a drive component 63. One end of each first lead screw 311 extends through the mounting portion 230 and is coaxially connected to the drive wheel 61. The drive belt 62 is driven by the multiple drive wheels 61. The drive component 63 is a motor or similar device. The drive component 63 is driven by one drive wheel 61, so that the drive component 63 synchronously drives each drive wheel 61 to rotate, thereby driving the first lead screw 311 connected to each drive wheel 61 to rotate synchronously. This causes the moving clamp 331 and the fixed clamp 332 to pull out or insert the clamped cable into the interface end 22 along the first direction Y.

[0072] It is understood that in some other embodiments, the end of the first lead screw 311 away from the mounting part 230 passes through the second cabinet 20 and the first cabinet 10 in sequence and is exposed in the first cabinet 10. The end of the first lead screw 311 exposed in the first cabinet 10 is provided with a handwheel so that each first lead screw 311 can be driven to rotate manually, thereby independently controlling each plug-in assembly 30 to plug in or unplug.

[0073] It is worth noting that when the first lead screw 311 passes through the first cabinet 10, a channel can be opened in the area between adjacent drawer cavities 11 to allow the first lead screw 311 to pass through.

[0074] The working method of this application is explained below:

[0075] When it is necessary to clamp a portion of the cables in the same row, the current connected to each corresponding adjustment structure 51 is adjusted according to the outer diameter of the cables to be clamped, thereby adjusting the initial distance between the support plate 52 and the moving clamp 331. Subsequently, the lifting drive 321 corresponding to the cable to be clamped is controlled to move, so that the support protrusion 342 corresponding to the cable to be clamped is lowered into the mounting cavity 430, while the support protrusion 342 corresponding to the cable not to be clamped remains outside the mounting cavity 430. Subsequently, the second lead screw 411 rotates to drive the sliding boxes 43. After each sliding box 43 moves a different distance, it begins to slide against the moving clamp 331 towards the fixed clamp 332. After each moving clamp 331 has pressed the cable against the fixed clamp 332 along the third direction X, the second lead screw 411 stops rotating and controls each lifting drive 321 to continue operating. The lowering distance of the lifting plate 322 is adjusted according to the outer diameter of the cable corresponding to each lifting drive 321, so that each moving clamp 331 presses the cable against the fixed clamp 332 in the second direction Z. Next, the first lead screw 311 rotates to control the moving clamp 331 and the fixed clamp 332 to move the clamped cable towards the interface end 22 until the cable insertion interface end 22. During this process, the abutment protrusion 342 remains inside the sliding box 43.

[0076] After the cable is inserted into the interface 22, the second lead screw 411 rotates in the opposite direction, and the sliding box 43 moves to the left along the third direction X, causing the moving clamp 331 to move away from the fixed clamp 332. Subsequently, the lifting drive 321 drives the abutment protrusion 342 to leave the sliding box 43, thereby completely releasing the cable.

[0077] When it is necessary to plug in or unplug another row of cables, the second lead screw 411 is driven to rotate, causing the sliding box 43 to move to the left along the third direction X to the area on the left side of the mounting plate 34, ensuring that the mounting plate 34 does not obstruct the up and down movement of the sliding box 43. Subsequently, the third lead screw 421 is driven to rotate until each sliding box 43 moves to below the plug-in assembly 30 corresponding to the other row of cables.

[0078] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the scope of this application. All such changes and substitutions fall within the scope defined by this application.
