Description

Technical Field

[0001] This invention relates to the field of cable branching technology, and in particular to a branching box for cable combing. Background Technology

[0002] In the field of power cable wiring construction, cable distribution boxes are core equipment for realizing the branching of main cables and the routing of cables, and are widely used in power distribution, building, municipal power and other scenarios. At present, conventional cable distribution boxes on the market have simple structural designs and mostly only have basic cable branching and storage functions, which have many defects in actual use.

[0003] Traditional branch boxes lack a dedicated cable management structure, resulting in a chaotic arrangement of multiple branch cables that are prone to tangling, crossing, and compression. This is not only unsightly but also leads to uneven heat dissipation, accelerates insulation aging, and makes it difficult to quickly identify the corresponding lines during later maintenance and troubleshooting, significantly increasing maintenance complexity. Secondly, the fixed cable outlet structure of existing branch boxes cannot accommodate cables of different diameters, resulting in poor sealing. External dust and moisture can easily enter the box through the gaps between the cables and the outlets, causing internal components to become damp and accumulate dust, potentially leading to short circuits, electrical leaks, and other safety hazards.

[0004] In addition, conventional cable fixing structures have poor adaptability, can only clamp cables of a single specification, and are prone to springback and misalignment after being straightened and combed, making it impossible to maintain a neat wiring state. At the same time, they lack automated opening and closing structures, making cable disassembly and wiring operations cumbersome, construction efficiency low, and difficult to meet the diverse and standardized cable wiring construction needs. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention adopts the following technical solution: a branch box for cable management, comprising a box body component, the box body component including a box body, a support provided in the box body, a main divider provided on the upper part of the support, and multiple dividers provided on the lower part of the support, the main divider and the dividers being connected by a branch line group, and multiple round holes provided on the two side panels and the bottom panel of the box body, the number of round holes on each panel being equal to the number of dividers.

[0006] The top panel of the enclosure has openings through which the main cable passes into the enclosure. The main cable connects to the input terminal of the main isolator. The branch line group consists of three sets of branch lines. The main line of each branch line is connected to one phase terminal of the output terminal of the main isolator, and the branch lines are sequentially connected to the input terminals of the isolators. Once the main cable is energized, power can be transmitted to each isolator through the branch lines.

[0007] Depending on the actual usage requirements, the cable can be selected to pass through different round holes to the outside of the box, and the direction of the cable exit can be flexibly selected, making it more convenient for on-site use.

[0008] Furthermore, the housing is equipped with a distribution plate, which has multiple T-slots in both the vertical and horizontal directions. The number of T-slots in each direction is equal to the number of separators. Each side wall of the T-slot is equipped with a limiting platform.

[0009] The vertical T-slots are aligned sequentially with the corresponding circuit breakers. Cables connected to the circuit breakers are first laid downwards along the T-slots, and the horizontal T-slots are aligned sequentially with the corresponding round holes. When a cable extends from the bottom panel of the enclosure, the corresponding cable is laid downwards only along the vertical T-slots; when a cable extends from the side panel of the enclosure, the cable is passed through the corresponding round hole and laid along the corresponding horizontal T-slots.

[0010] Furthermore, the cable distribution plate is equipped with a cable clamping component for combing cables. The cable clamping component includes a T-shaped block. Both sides of the T-shaped block are provided with a lower long groove and an upper long groove. A horizontal pressure block is slidably inserted into the upper long groove. The horizontal pressure block is slidably mounted on a slide rod. A spring is sleeved in the slide rod. The two ends of the spring are connected to the T-shaped block and the horizontal pressure block, respectively. A vertical plate is provided on the horizontal pressure block. The vertical plate is provided with a plug for insertion into the lower long groove. The plug is provided with an inclined surface to facilitate insertion into the T-shaped groove.

[0011] Furthermore, the side of the insert block is provided with a limiting groove for the insertion of the limiting platform.

[0012] When installing the cable clamping component, align the two beveled surfaces of the component with the T-slot and press the component into the T-slot. The edges of the T-slot apply pressure to the beveled surfaces, causing the two inserts to retract inward along the lower long slot. The vertical plate and horizontal pressure block then slide inward along the slide rod, stretching and storing energy in the corresponding spring. Once the cable clamping component is fully inserted, the inserts align with the bottom of the T-slot, and the spring provides tension, causing the corresponding vertical plate and inserts to move outward. The inserts then extend outward from the lower long slot. Adjust the position of the cable clamping component within the T-slot appropriately until the limiting platform inserts into the limiting slot. The cable clamping component will then no longer move within the T-slot, allowing it to be installed for clamping the corresponding cable.

[0013] Furthermore, two clamping plates are symmetrically slidably provided on the upper part of the T-shaped block. The T-shaped block is provided with a boss. A spring is connected between the clamping plate and the boss of the T-shaped block. The clamping plate is provided with two shaft holes. The shaft holes of the clamping plate are connected to the outer ring of the one-way bearing. The inner ring of the one-way bearing is provided with a clamping concave post. The clamping concave post is composed of two cone-shaped bodies, and the small ends of the two cone-shaped bodies of the clamping concave post are connected.

[0014] When the inner ring of the one-way bearing rotates in the clockwise direction, the outer ring does not rotate. When the inner ring rotates in the counterclockwise direction, the outer ring rotates synchronously. Therefore, the outer ring of the one-way bearing is fixedly installed in the clamping plate, and the inner ring of the one-way bearing can only rotate in the clockwise direction.

[0015] The cable is placed between the two rows of clamping posts. Spring two provides tension, causing both rows of clamping plates to clamp towards the center simultaneously. That is, the central recess of the two rows of clamping posts holds the cable. The clamping posts can hold cables of different diameters. After each cable is placed into its corresponding clamping component, the cable is straightened starting from the separator. During the straightening process, the clamping posts roll on the cable, rotating in the same direction. Because the clamping posts can only rotate in the same direction, the cable will not move in the opposite direction after straightening, making cable straightening more convenient.

[0016] Furthermore, both ends of the clamping plate are provided with vertical guide posts, and the upper end of the vertical guide posts is provided with slanted guide posts to facilitate the installation of cables.

[0017] When installing cables in the cable clamping assembly, align the cable with the angled guide post and press the cable towards the clamping post. The cable applies pressure to the angled guide post, causing the two clamping plates to move outwards. When the cable is pressed into the middle of the two rows of clamping posts, the cable separates from the vertical and angled guide posts. Therefore, the middle part of the clamping posts can clamp the cable securely. To separate the cable, pull the angled guide post, causing the two rows of clamping plates to move outwards, allowing the cable to be removed.

[0018] Furthermore, the box body is equipped with sealing components at the circular holes. The sealing components include sealing plates, which are fixed on the panel of the box body. A through hole is provided at the center of the sealing plate, and the through hole of the sealing plate coincides with the circular hole. A slide is provided on the sealing plate, and four layers of slide grooves are evenly provided in the slide from away from the sealing plate to close to the sealing plate. A sealing slide plate is symmetrically provided in each slide groove. A central platform is provided in the middle of each slide groove. A central hole is provided on both sides of the sealing slide plate, and a spring is installed in the central hole. The spring is connected to the corresponding central platform. A sealing arc gasket is provided in the middle of the first three layers of sealing slide plates. The sealing arc gaskets on the first to the third layers of sealing slide plates decrease in size sequentially. A sealing long gasket is provided in the middle of the fourth layer of sealing slide plate.

[0019] When the cable passes through the round hole, it simultaneously passes through the sealing component, that is, through the through hole of the corresponding sealing plate. Spring three provides tension, causing all the sealing plates to move towards the center along the groove. When there is no cable in the sealing component, the fourth layer of sealing plates moves closer together, that is, the two sealing gaskets contact each other, sealing the corresponding round hole and the through hole of the sealing plate, preventing dust from entering the cabinet. When there is a cable in the sealing component, all four layers of sealing plates move towards the center simultaneously. According to the different diameter specifications of the cable, the corresponding sealing plate and sealing arc gasket adaptively clamp the cable, and the sealing arc gasket and the cable are tightly sealed, thus preventing dust from entering the cabinet. The three sealing arc gaskets of different specifications can accommodate cables of different diameter specifications. Moreover, after the sealing arc gasket clamps the cable, it can also clamp and fix the cable.

[0020] Furthermore, the first layer of the dense slide plate is equipped with a pull plate, and the sides of the second to fourth layers of the dense slide plate are equipped with hanging plates, and the hanging plates on each layer of the dense slide plate are in contact with the layer above.

[0021] Pulling the pull plate on the first layer of sealing plates outward transmits power through the hanging plates of each group, causing each group of sealing plates to move outward synchronously. When the sealing component seals the cable, spring three pulls each group of sealing plates individually. Since the sealing arc pads on the first to third layers of sealing plates decrease in size sequentially, the sealing plates closer to the sealing plate side will preferentially move closer and clamp, and the hanging plate structure will not interfere with the cable sealing operation of the sealing arc pads.

[0022] Furthermore, both first-layer sealing plates of the sealing component are provided with slide bars, and the slide bars are provided with racks. Both racks mesh with gears, and the gears are rotatably located on the side of the slide frame.

[0023] When the sealing component clamps the cable, it pulls the outer plate outward, causing the first outer sealing plate to move outward. Power is transmitted through the slide bar, gear and rack, causing the first inner sealing plate to move outward synchronously. Therefore, all the sealing plates move outward at the same time.

[0024] Furthermore, the back panel of the housing is equipped with four electric cylinders, and the telescopic shafts of the four electric cylinders are provided with three side frames, which are used to drive the pull plates on each inner side.

[0025] When it is necessary to open the sealing components simultaneously, the four electric cylinders retract at the same time, driving the three side frames to move. The three side frames then drive the pull plates inside all the sealing components to move, thus opening all the sealing components and facilitating the installation of cables.

[0026] The advantages of this invention compared to the prior art are: (1) The present invention has a cable distribution board with horizontal and vertical T-shaped grooves inside the box, which can flexibly select the cable to come out from the side plate or the bottom plate of the box according to the construction needs, adapting to different on-site wiring conditions. With the help of special cable clamping components, each cable is independently positioned and clamped, realizing the orderly and directional laying of cables in sections, completely solving the problems of cable tangling and crossover in traditional branch boxes. At the same time, relying on the characteristic of the one-way bearing driving the cable clamping column to rotate in one direction, the cable can be straightened and sorted and then locked in the reverse direction, effectively preventing the cable from springing back and misaligning, maintaining the neat wiring inside the box for a long time, and greatly reducing the probability of line failure and the difficulty of later operation and maintenance.

[0027] (2) The clamping component of this invention adopts an elastic clamping structure, combined with a bidirectional conical combined clamping concave column, which can adaptively clamp cables of different diameters, breaking the limitation of traditional fixing clamps that can only adapt to a single specification of cable. At the same time, the sealing component is equipped with three layers of sealing arc gaskets of different sizes combined with sealing long gaskets, which can adaptively fit and seal according to the cable diameter, and can adapt to the wiring needs of cables of various thicknesses. It can adapt to different construction scenarios without changing parts, and the versatility of the equipment is significantly improved. (3) This invention provides a sealing component at each cable outlet. This sealing component, through multiple layers of sealing plates with sealing arc gaskets of different specifications, can automatically match and tightly fit according to the actual diameter of the cable, thereby achieving adaptive sealing. At the same time, holes where no cable passes through can be completely sealed by the sealing gasket, effectively preventing dust and moisture from entering the enclosure and ensuring the safe operation of the internal electrical components. (4) The cable components of this invention adopt a plug-in limiting installation structure, which enables quick assembly and disassembly through inclined guide and spring self-locking. Combined with the inclined guide square column guide structure, the cable insertion and removal operations are simple and labor-saving. At the same time, the sealing components are equipped with a gear rack linkage structure and an electric cylinder driven three-sided linkage mechanism, which can realize the synchronous opening and closing of all sealing structures. There is no need to manually operate the sealing components one by one, which greatly simplifies the operation process of cable laying, inspection and replacement, effectively reduces the labor intensity of construction personnel, and improves the work efficiency of power wiring and equipment maintenance.

Detailed Implementation

[0043] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0044] refer to Figures 1 to 2A branch box for cable management includes a box body component, which includes a box body 101. A bracket 102 is provided in the box body 101. A main disconnector 103 is provided on the upper part of the bracket 102. A plurality of partitions 104 are provided on the lower part of the bracket 102. The main disconnector 103 and the partitions 104 are connected by a branch line group 105. The two side panels and the bottom panel of the box body 101 are provided with a plurality of round holes 106. The number of round holes 106 on each panel is equal to the number of partitions 104.

[0045] Specifically, the top plate of the enclosure 101 has holes, through which the main cable passes into the enclosure 101. The main cable is connected to the input terminal of the main disconnector 103. The branch line group 105 consists of three sets of branch lines. The main line end of each branch line is connected to one phase terminal of the output terminal of the main disconnector 103, and the branch ends of the branch lines are connected sequentially to the corresponding phase terminals of the input terminals of the disconnectors 104. After the main cable is energized, power can be transmitted to each group of disconnectors 104 through the branch lines.

[0046] Depending on the actual usage requirements, the cable 204 can be selected to pass through different round holes 106 to the outside of the box 101, and the direction of the cable 204 can be flexibly selected, making it more convenient for on-site use.

[0047] refer to Figures 3 to 5 The housing 101 is provided with a dividing plate 201 inside. The dividing plate 201 has multiple T-slots 202 in both the vertical and horizontal directions. The number of T-slots 202 in each direction is equal to the number of separators 104. The two side walls of the T-slots 202 are provided with limiting platforms 203.

[0048] Specifically, the vertical T-slots 202 are aligned sequentially with the corresponding separators 104. The cables 204 connected to the separators 104 are first arranged downwards along the T-slots 202, and the horizontal T-slots 202 are aligned sequentially with the corresponding round holes 106. When the selected cable 204 extends from the bottom panel of the enclosure 101, the corresponding cable 204 is arranged downwards only along the vertical T-slots 202; when the selected cable 204 extends from the side panel of the enclosure 101, the cable 204 is passed through the round holes 106 of the corresponding side panel and arranged along the corresponding horizontal T-slots 202.

[0049] refer to Figures 6 to 10The cable divider 201 is equipped with a clamping component for combing the cable 204. The clamping component includes a T-shaped block 301. Both sides of the T-shaped block 301 are provided with a lower long groove 302 and an upper long groove 303. A horizontal pressure block 304 is slidably inserted into the upper long groove 303. The horizontal pressure block 304 is slidably mounted on a slide rod 305. A spring 306 is sleeved in the slide rod 305. The two ends of the spring 306 are respectively connected to the T-shaped block 301 and the horizontal pressure block 304. A vertical plate 307 is vertically provided on the horizontal pressure block 304. The vertical plate 307 is provided with an insertion block 308 for insertion into the lower long groove 302. The insertion block 308 is provided with an inclined surface 309 for easy insertion into the T-shaped groove 202.

[0050] The side of the insert block 308 is provided with a limiting groove 310, which is used for the insertion of the limiting platform 203.

[0051] Specifically, when installing the wire clamping component, align the two inclined surfaces 309 of the wire clamping component with the T-slot 202 and press the wire clamping component into the T-slot 202. Then, the edge of the T-slot 202 applies pressure to the inclined surfaces 309, and the two inserts 308 retract inward along the lower long groove 302. Then, the vertical plate 307 and the horizontal pressure block 304 slide inward along the slide rod 305, and the corresponding spring 306 stretches and stores energy. After the clamping component is pressed into place, the insert 308 coincides with the bottom of the T-slot 202. The spring 306 provides tension, causing the corresponding vertical plate 307 and insert 308 to move outward. The insert 308 extends out of the lower long slot 302 again, and the position of the clamping component in the T-slot 202 is appropriately moved so that the limiting platform 203 is inserted into the limiting slot 310. The clamping component no longer moves in the T-slot 202, and the clamping component can be installed in the T-slot 202 to clamp the corresponding cable 204.

[0052] Two clamping plates 311 are symmetrically slidably provided on the upper part of the T-shaped block 301. The T-shaped block 301 is provided with a boss. A spring 312 is connected between the clamping plate 311 and the boss of the T-shaped block 301. The clamping plate 311 is provided with two shaft holes. The shaft holes of the clamping plate 311 are connected to the outer ring of the one-way bearing 313. The inner ring of the one-way bearing 313 is provided with a clamping concave post 314. The clamping concave post 314 is composed of two cone-shaped bodies, and the small ends of the two cone-shaped bodies of the clamping concave post 314 are connected.

[0053] When the inner ring of the one-way bearing 313 rotates in the forward direction, the outer ring of the one-way bearing 313 does not rotate. When the inner ring of the one-way bearing 313 rotates in the reverse direction, the outer ring of the one-way bearing 313 rotates synchronously. Therefore, the outer ring of the one-way bearing 313 is fixedly installed in the clamping plate 311, and the inner ring of the one-way bearing 313 can only rotate in the forward direction.

[0054] Specifically, the cable 204 is placed between the two rows of clamping recesses 314. Spring 312 provides tension, causing the two rows of clamping plates 311 to clamp simultaneously towards the center. That is, the central recess of the two rows of clamping recesses 314 holds the cable 204. The clamping recesses 314 can hold cables 204 of different diameters. After each cable 204 is placed into its corresponding clamping component, the cable 204 is straightened starting from the separator 104. During the straightening process, the clamping recesses 314 roll on the cable 204, rotating in the same direction. Since the clamping recesses 314 can only rotate in the same direction, the cable 204 will not move in the opposite direction after being straightened, making the straightening process more convenient.

[0055] Both ends of the clamping plate 311 are provided with vertical guide posts 315, and the upper end of the vertical guide posts 315 is provided with an oblique guide post 316 for easy installation of cables 204.

[0056] Specifically, when installing cable 204 in the clamping component, align cable 204 with the oblique guide post 316 and press cable 204 towards the clamping recess 314. The cable 204 applies pressure to the oblique guide post 316, causing the two clamping plates 311 to move outwards. When cable 204 is pressed into the middle of the two rows of clamping recesses 314, cable 204 separates from the vertical guide post 315 and the oblique guide post 316. Therefore, the middle part of the clamping recesses 314 can clamp cable 204. To separate cable 204, pull the oblique guide post 316, causing the two rows of clamping plates 311 to move outwards, allowing cable 204 to be removed.

[0057] refer to Figures 11 to 14 The housing 101 is equipped with sealing components inside the housing and at the circular hole 106. Each sealing component includes a sealing plate 401, which is fixed to the panel of the housing 101. A through hole is located at the center of the sealing plate 401, coinciding with the circular hole 106. A slide 402 is mounted on the sealing plate 401. Four layers of sliding grooves 403 are evenly arranged in the slide 402 from the direction away from the sealing plate 401 to the direction closer to the sealing plate 401. Each sliding groove 403 is symmetrically equipped with a sealing strip. Plate 404, each layer of sliding groove 403 has a central platform 405 in the middle, the two sides of the close-slide plate 404 have central holes 407, springs 406 are installed in the central holes 407 and the springs 406 are connected to the corresponding central platforms 405, the middle of the first three layers of close-slide plates 404 is provided with sealing arc gaskets 408, the sealing arc gaskets 408 on the first layer of close-slide plate 404 to the third layer of close-slide plate 404 are progressively smaller, and the middle part of the fourth layer of close-slide plate 404 is provided with a sealing long gasket 409.

[0058] Specifically, when cable 204 passes through the round hole 106, cable 204 simultaneously passes through the sealing component, that is, cable 204 passes through the through hole of the corresponding sealing plate 401. Spring 3 406 provides tension, causing all sealing plates 404 to move towards the center along the slide groove 403. When there is no cable 204 in the sealing component, the fourth layer of sealing plates 404 move closer together, that is, the two sealing gaskets 409 contact each other, sealing the corresponding round hole 106 and the through hole of the sealing plate 401, preventing dust from entering the interior of the housing 101. When there is cable 204 in the sealing component, the four layers of sealing plates 404 move towards the center simultaneously. According to the different diameter specifications of cable 204, the corresponding sealing plate 404 and the cable 204 of the sealing arc gasket 408 are clamped together, and the sealing arc gasket 408 and the cable 204 are tightly sealed, thus preventing dust from entering the interior of the housing 101. The three sealing arc gaskets 408 of different specifications can accommodate cables 204 of different diameter specifications. Furthermore, the sealing arc gasket 408 can clamp and fix the cable 204 after clamping it.

[0059] The first layer of the dense slide plate 404 is provided with a pull plate 410, and the sides of the second to fourth layers of the dense slide plate 404 are provided with hanging plates 411, and the hanging plates 411 on each layer of the dense slide plate 404 are in contact with the layer above the dense slide plate 404.

[0060] Specifically, the pull plate 410 on the first layer of sealing slide plate 404 is pulled outward, and the power is transmitted through the hanging plates 411 of each group, so that each group of sealing slide plates 404 moves outward synchronously. When the sealing component seals the cable 204, the spring 3 406 pulls each group of sealing slide plates 404 individually. Since the sealing arc pads 408 on the first layer of sealing slide plate 404 to the third layer of sealing slide plate 404 decrease in size in sequence, the sealing slide plate 404 on the side closer to the sealing plate 401 will preferentially move closer and clamp, so the hanging plate 411 will not interfere with the sealing operation of the cable 204 of the sealing arc pad 408.

[0061] Both first-layer sealing slide plates 404 of the sealing component are provided with slide bars 412, and each slide bar 412 is provided with a rack 413. Both racks 413 mesh with gears 414, which are rotatably located on the side of the slide 402.

[0062] Specifically, when the sealing component clamps the cable 204, it pulls the outer pull plate 410 outward, causing the first outer sealing plate 404 to move outward. Power is transmitted through the slide bar 412, gear 414 and rack 413, causing the first inner sealing plate 404 to move outward synchronously. Therefore, all the sealing plates 404 move outward at the same time.

[0063] The back panel of the housing 101 is equipped with four electric cylinders 415. The telescopic shafts of the four electric cylinders 415 are provided with three side frames 416, which are used to drive the pull plates 410 on each inner side.

[0064] Specifically, when it is necessary to open the sealing components simultaneously, the four electric cylinders 415 retract at the same time, driving the three side frames 416 to move. The three side frames 416 simultaneously drive the pull plates 410 on the inside of all the sealing components to move, thereby opening all the sealing components and facilitating the installation of cables 204.

[0065] Working principle: When using the branch box, the main cable is inserted into the box 101 through the hole at the top of the box 101, and the hole at the top of the box 101 is sealed. The main cable is connected to the inlet terminal of the main disconnector 103. The disconnector 104 connects different cables 204. During the initial positioning of the cables 204, all cables 204 are arranged sequentially downwards along the T-slots 202. When a selected cable 204 extends from the bottom panel of the box 101, the corresponding cable 204 is arranged only downwards along the vertical T-slots 202. When a selected cable 204 extends from the side panel of the box 101, the cable 204 is passed through the circular hole 106 of the corresponding side panel and arranged along the corresponding horizontal T-slots 202. After the main cable is energized, power can be transmitted to each group of disconnectors 104 and cables 204 through the branch line group 105, achieving the function of power distribution. Depending on the actual usage requirements, the cable 204 can be selected to pass through different round holes 106 to the outside of the box 101, and the direction of the cable 204 can be flexibly selected, making it more convenient for on-site use.

[0066] After the cable 204 is initially positioned, the clamping components are installed at appropriate positions in the T-slots 202 in the horizontal and vertical directions to fix the cable 204. The two inclined surfaces 309 of the clamping components are aligned with the T-slots 202, and the clamping components are pressed against the T-slots 202. The edges of the T-slots 202 then apply pressure to the inclined surfaces 309. The two inserts 308 retract inward along the lower long groove 302, and the vertical plate 307 and the horizontal pressure block 304 slide inward along the slide bar 305. The corresponding spring 306 stretches and stores energy. After the clamping component is pressed into place, the insert 308 coincides with the bottom of the T-slot 202. The spring 306 provides tension, causing the corresponding vertical plate 307 and insert 308 to move outward. The insert 308 extends out of the lower long slot 302 again, and the position of the clamping component in the T-slot 202 is appropriately moved so that the limiting platform 203 is inserted into the limiting slot 310. The clamping component no longer moves in the T-slot 202, and the clamping component can be installed in the T-slot 202 to clamp the corresponding cable 204.

[0067] Align cable 204 with the oblique guide post 316 and press cable 204 towards the clamping post 314. The cable 204 applies pressure to the oblique guide post 316, driving the two clamping plates 311 to move outward. When cable 204 is pressed into the middle part of the two rows of clamping posts 314, cable 204 separates from the vertical guide post 315 and the oblique guide post 316. Spring 2 312 provides tension, causing the two rows of clamping plates 311 to clamp inward simultaneously. That is, the middle recess of the two rows of clamping posts 314 clamps cable 204. The clamping posts 314 can clamp cables 204 of different diameters. After each cable 204 is placed into the corresponding clamping component, start straightening cable 204 from the separator 104. During the straightening process, the clamping posts 314 roll on cable 204, that is, the clamping posts 314 rotate in the same direction. Since the clamping post 314 can only rotate in the forward direction, the cable 204 will not move in the reverse direction after being straightened, making it more convenient to straighten the cable 204. When it is necessary to separate the cable 204, pull the inclined guide post 316 to move the two rows of clamping plates 311 outward, and the cable 204 can be removed; when it is necessary to remove the clamping component from the T-slot 202, press the two horizontal pressure blocks 304 to retract the insertion block 308 into the T-block 301, and the clamping component can be removed.

[0068] When cable 204 passes through the round hole 106, it simultaneously passes through the sealing component. Pulling the pull plate 410 on the first layer of sealed slide plate 404 outward transmits power through the hanging plates 411 of each group, and also through the slide bar 412, gear 414, and rack 413, driving the inner sealed slide plate 404 of the first layer to move outward synchronously. Therefore, all the sealed slide plates 404 move outward at the same time, allowing cable 204 to pass through the through hole of the corresponding sealed plate 401. Releasing the pull plate 410, the spring 406 provides tension, causing all the sealed slide plates 404 to move towards the center along the slide groove 403. When there is no cable 204 in the sealing component, the sealed slide plates 404 of the fourth layer come together, that is, the two sealing pads 409 contact each other, sealing the corresponding round hole 106 and the through hole of the sealed plate 401, preventing dust from entering the interior of the housing 101. When there is a cable 204 in the sealed component, the four sealing slide plates 404 move towards the center simultaneously. Depending on the diameter of the cable 204, the corresponding sealing slide plate 404 and sealing arc gasket 408 adaptively clamp the cable 204, ensuring a tight seal between the sealing arc gasket 408 and the cable 204. This prevents dust from entering the housing 101. The three different sizes of sealing arc gaskets 408 can accommodate cables 204 of different diameters. Furthermore, after clamping the cable 204, the sealing arc gasket 408 also secures the cable 204. When it is necessary to open the sealed components simultaneously, the four electric cylinders 415 retract simultaneously, driving the three side frames 416 to move. The three side frames 416 simultaneously drive the pull plates 410 on the inside of all the sealed components to move, thus opening all the sealed components and facilitating the installation of the cable 204.
