Description

Technical Field

[0001] This invention relates to the technical field of distribution boxes, and in particular to a distribution box with a cable management structure. Background Technology

[0002] A distribution box is a low-voltage power distribution device that assembles switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Multiple wires are connected inside the distribution box, and some wires extend to the outside of the distribution box to connect with other lines or electrical equipment.

[0003] Currently, after electrical components are installed inside existing distribution boxes, there are many wires inside the boxes, and there is a lack of corresponding wire management measures. Some of the wires are quite long, and some of the longer wires are coiled up inside the distribution box, which may cause the wires to become tangled. When a fault occurs, it will be inconvenient for staff to inspect and maintain the wires. Summary of the Invention

[0004] To address the issues of numerous wires in distribution boxes, lack of appropriate wire management measures, and the fact that some wires are quite long and may become tangled, making it difficult for staff to inspect and maintain the lines when a fault occurs, this application provides a distribution box with a wire management structure.

[0005] The electrical distribution box with cable management structure provided in this application adopts the following technical solution:

[0006] A distribution box with a cable management structure includes a box body, a cable management box inside the box body, and multiple cable routing channels inside the cable management box. Both ends of the bottom surface of the cable management box have slots that communicate with the multiple cable routing channels. Each cable routing channel has a rotatable take-up reel. The take-up reel includes a hollow shaft tube that rotates vertically within the cable routing channel. Two baffles are fixedly fitted onto the outer circumferential surface of the hollow shaft tube, and cable routing holes are formed on the outer circumferential surface of the hollow shaft tube. The cable management box is equipped with a fixing component for securing the take-up reel.

[0007] By adopting the above technical solution, when wiring electrical appliances such as switches and measuring instruments inside the enclosure, the wires that need to be connected to each instrument are passed through the slots, moving the wires into the wiring channel. Then, the front end of the wire is inserted into the hollow shaft tube through the wiring hole. The wire is moved further until the front end of the wire passes out of the hollow shaft tube, and the wire is pulled so that the wire's terminal is at the connection point of the electrical appliance. When the wire length reserved above the hollow shaft tube is sufficient to connect to the electrical appliance, the hollow shaft tube is rotated, causing the hollow shaft tube to rotate and the wire to rotate, so that the excess long wire is wrapped around the hollow shaft tube. This reduces the possibility of long wires getting tangled together when there are many wires inside the enclosure, and makes it easier for staff to inspect and maintain the circuit when a fault occurs.

[0008] Preferably, the top of the cable management box is provided with a cover, and studs are fixed at the corners of the top surface of the cable management box. Through holes are opened at the corners of the top surface of the cover. The studs pass through the through holes, and a wing nut is fitted on the stud. The wing nut is threaded to the stud, and the bottom end of the wing nut abuts against the top surface of the cover.

[0009] By adopting the above technical solution, when a line fault occurs, the staff can rotate the wing nut to disengage it from the stud, and then remove the cover from the cable management box, which makes it easier for the staff to check the lines inside the cable management box.

[0010] Preferably, the top surface of the box cover has multiple openings, which correspond to multiple wiring channels. The top end of the hollow shaft tube passes through the openings. The fixing member includes a limiting block sleeved on the top end of the hollow shaft tube. The limiting block is slidably connected to the hollow shaft tube in the vertical direction. Both sides of the limiting block are fixed with protrusions. The limiting block is inserted into the opening. The two sides of the limiting block are in contact with the opposite inner sides of the opening. The bottom surface of the protrusion is in contact with the top surface of the box cover.

[0011] By adopting the above technical solution, when the staff fixes the cover to the cable management box, the top of the hollow shaft tube passes through the opening. The staff then places the limiting block on the hollow shaft tube. By rotating the stop block, the stop block drives the limiting block to rotate, which in turn drives the hollow shaft tube to rotate, allowing the wire to be wound around the hollow shaft tube. After the wire is arranged, the limiting block is moved downwards so that the bottom end of the limiting block is inserted into the opening, and the bottom surface of the stop block is in contact with the top surface of the cover, thereby reducing the possibility of the wire wound on the hollow shaft tube springing back and causing the hollow shaft tube to rotate.

[0012] Preferably, the inner bottom surface of the cable routing channel is provided with multiple recessed grooves, one end of which is rotatably mounted with a vertical pole, and a fixing component for fixing the vertical pole is provided in the recessed groove.

[0013] By adopting the above technical solution, when the wire wound on the take-up reel is still long, rotate two of the uprights on the bottom surface of the cable routing channel to make the uprights rotate to a vertical position, then fix the uprights with the second fixing piece, and then wind the wire around the two uprights to further wind and organize the wire.

[0014] Preferably, the sink is provided with grooves on both sides, the grooves penetrate the inner bottom surface of the wiring channel, the second fixing member includes a limiting plate disposed above the upright, the bottom surface of the limiting plate is in contact with the top surface of the groove, and a rotating shaft is fixed to one end of each side of the limiting plate, and the two rotating shafts are respectively rotatably installed on the inner wall of the two grooves.

[0015] By adopting the above technical solution, the limiting plate is rotated to open the sink, and then the upright is rotated to a vertical position. Next, the limiting plate is rotated to a horizontal position so that the end of the limiting plate away from the rotating shaft abuts against the outer circumference of the upright, thereby restricting the rotation of the upright.

[0016] Preferably, a movable block is provided on the bottom surface of the wiring channel, and grooves are provided on the opposite inner surfaces of the wiring channel. The two ends of the movable block are respectively inserted into the two grooves, and the two ends of the movable block are slidably disposed in the two grooves. The bottom end of the hollow shaft tube is rotatably mounted on the top surface of the movable block.

[0017] By adopting the above technical solution, the hollow shaft tube is rotatably installed on the top surface of the movable block, which facilitates the movement of the hollow shaft tube along the length of the cable management box and the adjustment of the wiring position of the wires.

[0018] Preferably, two mounting rods are fixed on both sides of the inner bottom surface of the box, and two movable rings are fixed on both ends of the cable management box. The movable rings are sleeved on the outer circumferential surface of the mounting rods, and the mounting rods are provided with limiting members to restrict the downward movement of the movable rings.

[0019] By adopting the above technical solution, when some electrical appliances are located at a high position inside the cabinet, the cable management box is moved upward, which in turn moves the moving ring upward. When the cable management box is in the correct position, the moving ring is fixed to the mounting rod by a limiting component, thereby restricting the downward movement of the cable management box. This reduces the possibility that the exposed wires above the cable management box are too long and the wires will get tangled together when wiring.

[0020] Preferably, the outer circumferential surface of the mounting rod is provided with multiple annular grooves, and the limiting member includes a rotating ring rotatably installed in the annular groove. A positioning block is fixed on the outer circumferential surface of the rotating ring, and the top end of the positioning block abuts against the bottom surface of the cable management box.

[0021] By adopting the above technical solution, when the cable management box is moved to the correct position, the positioning block is rotated, which drives the rotating ring to rotate, so that the positioning block moves to the bottom of the moving ring, and the fixed surface of the positioning block abuts against the bottom surface of the moving ring, thereby restricting the cable management box from moving downward.

[0022] Preferably, the outer circumferential surface of the moving ring is provided with a clearance groove, the clearance groove extends vertically through the moving ring, and the positioning block can pass through the clearance groove.

[0023] By adopting the above technical solution, a clearance groove is opened on the outer circumference of the moving ring. When it is necessary to move the cable management box vertically, the limiting block is rotated to the clearance groove position, thereby facilitating the vertical movement of the cable management box.

[0024] Preferably, a surrounding plate is provided on one side of the two mounting rods, and two retaining rings are fixed on the inner side of the surrounding plate, the retaining rings being engaged with the outer peripheral surface of the mounting rods.

[0025] By adopting the above technical solution, the enclosure is secured to the mounting rod with a snap ring, so that the wires are enclosed inside the enclosure, which makes it easier to manage the wires under the offline board.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When wiring electrical equipment such as switches and measuring instruments inside the enclosure, pass the wires that need to be connected to each instrument through the slots to move the wires into the wiring channel. Then, insert the front end of the wire through the wiring hole into the hollow shaft tube. Continue to move the wire so that the front end of the wire passes out of the hollow shaft tube. Pull the wire so that the wire terminal is at the wiring point of the electrical appliance. When the wire length reserved above the hollow shaft tube is sufficient to connect to the electrical appliance, rotate the hollow shaft tube to make the hollow shaft tube rotate, so that the excess and longer wires are wrapped around the hollow shaft tube. This reduces the possibility of long wires getting tangled together when there are many wires inside the enclosure. In addition, it is easier for staff to inspect and maintain the circuit when a fault occurs.

[0028] 2. When the staff fixes the box cover onto the cable management box, the top of the hollow shaft tube passes through the opening. The staff puts the limiting block on the hollow shaft tube. By rotating the stop block, the stop block drives the limiting block to rotate, and the limiting block drives the hollow shaft tube to rotate, so that the hollow shaft tube can wrap the wires around it. After the wires are arranged, the limiting block is moved downward so that the bottom end of the limiting block is inserted into the opening. The bottom surface of the stop block is in contact with the top surface of the box cover, thereby reducing the possibility of the wires wrapped on the hollow shaft tube springing back and causing the hollow shaft tube to rotate.

[0029] 3. When some electrical appliances are positioned high inside the cabinet, the cable management box is moved upwards, which in turn moves the moving ring upwards. Once the cable management box is in the correct position, the moving ring is fixed to the mounting rod by a limiting component, thereby restricting the cable management box from moving downwards. This reduces the possibility of long exposed wires above the cable management box causing the wires to become tangled during wiring. Attached Figure Description

A rotating shaft 34 is fixed to one end of each of the two sides of the limiting plate 33, and the two rotating shafts 34 are rotatably installed on the inner sides of the two grooves 32 respectively.

[0042] Reference Figure 3 and Figure 6The cable management box 2 has a cover 4 at its top. Studs 41 are fixed to the corners of the top surface of the cable management box 2. Through holes 42 are provided at the corners of the top surface of the cover 4, through which the tops of the studs 41 pass. A wing nut 43 is fitted onto the stud 41, threadedly connected to it. The bottom of the wing nut 43 abuts against the top surface of the cover 4. Multiple openings 44 are provided on the top surface of the cover 4, corresponding to multiple cable routing channels 21. The top of the hollow shaft tube 251 passes through the openings 44. A limiting block 45 is fitted onto the top of the hollow shaft tube 251, sliding vertically with it. The bottom of the limiting block 45 is inserted into the opening 44, with its two sides abutting against the opposite inner surfaces of the opening 44. Both sides of the limiting block 45 are fixed with protrusions 46, and the bottom surface of the protrusions 46 is in contact with the top surface of the box cover 4.

[0043] Reference Figure 3 and Figure 6 Two vertically arranged mounting rods 5 are fixed on both sides of the inner bottom surface of the box 1. Moving rings 51 are fixed to both ends of the cable management box 2, and the moving rings 51 are fitted onto the outer circumferential surface of the mounting rods 5. Multiple annular grooves 52 are formed on the outer circumferential surface of the mounting rods 5, and these grooves are equally spaced vertically. Rotating rings 55 are rotatably installed within the annular grooves 52. The outer circumferential surface of the rotating rings 55 is coplanar with the outer circumferential surface of the mounting rods 5. Positioning blocks 53 are fixed to the outer circumferential surface of the rotating rings 55, with the top of one of the positioning blocks 53 abutting against the bottom surface of the cable management box 2. A clearance groove 54 is formed on the outer circumferential surface of the moving rings 51, penetrating vertically through the moving rings 51. The positioning blocks 53 can pass through the clearance groove 54.

[0044] Reference Figure 3 and Figure 6 A U-shaped plate 6 is provided on one side of each of the two mounting rods 5. Two retaining rings 61 are fixed to the inner side of the plate 6, and the retaining rings 61 are engaged with the outer circumference of the mounting rods 5. A guide strip 62 is fixed to the inner side of the plate 6. Multiple guide holes 63 are provided on the side of the guide strip 62, and the guide holes 63 penetrate the guide strip 62 vertically.

[0045] One side of the wire enclosed inside the enclosure 6 is threaded through the wire insertion hole, which makes it easier to fix the position of the wire located below the cable management box 2, thereby reducing the possibility of the wires located below the cable management box 2 getting tangled together.

[0046] The implementation principle of a distribution box with a cable management structure according to an embodiment of this application is as follows: When it is necessary to connect electrical appliances in the distribution box, the wire is passed through the wire through holes 14 on both sides of the bottom surface of the distribution box. Then, the wire is passed through the slots 22 at both ends of the bottom surface of the cable management box 2 into the cable routing channel 21. Then, the wire end is passed through the cable routing hole 253 and into the hollow shaft tube 251. The wire is moved so that the wire end passes out of the hollow shaft tube 251, and the wire end is pulled upward to pull out part of the wire, so that the wire end above the hollow shaft tube 251 can extend to the connection port of the electrical appliance. Then, the limiting block 45 is fitted onto the top of the hollow shaft tube 251. The protrusion 46 is rotated, and the protrusion 46 drives the limiting block 45 to rotate. The limiting block 45 drives the hollow shaft tube 251 to rotate, and the hollow shaft tube 251 drives the wire to rotate, winding the longer wire onto the hollow shaft tube 251. When the wire wound on the take-up reel 25 is still relatively long, open the two adjacent limiting plates 33 on the bottom surface of the cable routing channel 21, then rotate the upright 31 in the sink 3 to make the upright 31 rotate to a vertical position. Next, rotate the limiting plate 33 to make the limiting plate 33 rotate to a horizontal position, so that the end of the limiting plate 33 away from the rotating shaft 34 abuts against the outer circumference of the upright 31, thereby restricting the rotation of the upright 31. Then, wrap the wire around the two upright 31 to further wind up and organize the wire, thereby reducing the possibility of long wires getting tangled together when there are many wires in the box 1. This makes it easier for staff to inspect and maintain the line when a fault occurs. After the wire is wound up, place the cover 4 on top of the cable management box 2, allowing the wire end to pass through the opening 44 on the cover 4. Then, place the cover 4 on the top surface of the cable management box 2, with the stud 41 on the cable management box 2 passing through the through hole 42 on the cover 4. Next, put the wing nut 43 on the stud 41 and rotate the wing nut 43 so that its bottom end abuts against the top surface of the cover 4, thus fixing the cover 4 to the cable management box 2. Then, place the limiting block 45 on the top of the hollow shaft tube 251 and move the limiting block 45 downward so that its bottom end is inserted into the opening 44, with the bottom surface of the protrusion 46 abutting against the top surface of the cover 4, thereby restricting the rotation of the hollow shaft tube 251.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
