Description

Technical Field

[0001] This invention belongs to the field of power distribution cabinet technology, and particularly relates to a power distribution cabinet for switching power supplies. Background Technology

[0002] Switching power supply distribution cabinets are key power distribution equipment specifically designed for switching power supply systems. They are used to safely and efficiently distribute and manage power. The organization and arrangement of the internal wires of the switching power supply distribution cabinet is an important part of the installation and maintenance of electrical components in the distribution cabinet. Its purpose is to ensure the safety and reliability of electrical components in the distribution cabinet.

[0003] Currently, after installation, the electrical components inside the distribution cabinet need to be connected by wires. The main types of wires include power lines, communication lines, and grounding wires. Since the distribution of electrical components is not specific, many wires become intertwined after wiring. Therefore, after wiring, operators need to properly bundle the wires together and then place the bundled wires into the wire trough.

[0004] However, with the continuous development of distribution cabinet technology, when the electrical components inside the distribution cabinet need to be upgraded or expanded, it is necessary to remove the electrical components and replace them with a different type of electrical component. During the replacement, the new electrical component may have a different wiring position or other differences, resulting in insufficient length of the original wire, making it impossible for the wire to be directly connected to the new electrical component. If the end of the wire is cut off and the wire is paralleled to extend the wire, it may have a certain impact on the communication of the wire and also pose certain safety risks. Furthermore, by bundling all the wires on a path and placing them in the wire trough, some high-voltage wires will have a high operating temperature, which will not only cause high temperature but also adversely affect the communication of low-voltage wires. Summary of the Invention

[0016] Compared with the prior art, the power distribution cabinet for switching power supplies provided in this embodiment of the invention has the following beneficial effects:

[0017] 1. In this invention, the winding mechanism, in conjunction with the winding tube, can collect and organize excess wires in the conductor, making the conductor more neat. Furthermore, when electronic components inside the distribution cabinet are replaced, the collected wires can be extended to accommodate the power connection of the replaced electronic components, thereby avoiding the safety risks caused by secondary wiring of the conductors.

[0018] 2. In this invention, the inner support mechanism provided on the winding tube can simultaneously fix all the winding mechanisms on the winding tube, which makes it easier for the winding mechanism to adjust its fixed position according to the specific position of the electronic component, thus improving its applicability.

[0019] 3. In this invention, the positioning mechanism can fix all wire structures at the same horizontal position inside the power distribution cabinet and push them into the electronic component interface above the positioning mechanism, which facilitates the subsequent installation of wire connectors into the electronic component interface using external tools.

[0020] 4. In this invention, the piston plate inside the air box is driven to reciprocate by the set driving mechanism, so that the surface of the isolation plate generates negative pressure to draw in air, and the hot air inside the first junction box is drawn out for cooling, which can avoid the influence of excessive temperature on the weak current wires.

[0021] 5. In this invention, the drive mechanism not only drives the piston plate inside the air box to work, but also synchronously drives the brush plate to rotate around the dustproof net to remove dust from the dustproof net. It also draws out the hot air from the first junction box and sends it into the brush plate, which is then sprayed out from the air outlet on the side of the brush plate closest to the dustproof net, thereby improving the dust removal effect of the brush plate on the dustproof net and thus making it more conducive to the air circulation inside the cabinet.

[0034] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0035] Please refer to the following: Figure 1 , Figure 2 and Figure 3A distribution cabinet for a switching power supply includes a cabinet body 1. First junction boxes 2 are fixedly installed on the inner walls of both sides of the cabinet body 1. Multiple second junction boxes 3 with a U-shaped structure are fixedly installed on the inner wall of the rear side of the cabinet body 1. A guide mechanism 4 is installed on the inner wall of the rear side of the second junction boxes 3. A winding tube 5 is rotatably installed between the inner walls of the left and right sides of the second junction boxes 3. Several winding mechanisms 6 are installed on the surface of the winding tube 5. An inner support mechanism 7 for locking the winding mechanisms 6 is installed on the winding tube 5. A positioning mechanism 8 for locking wire connectors is movably installed on the upper part of the second junction boxes 3. The winding mechanisms 6 can slide and adjust to align according to the specific position of the electronic components. Then, the winding mechanisms 6 are fixed by the inner support mechanism 7. After one end of the wire is guided by the guide mechanism 4, part of the wire is wound around the winding mechanism 6 by rotation. Then, the positioning mechanism 8 fixes the position of the wire connectors. After all connectors are aligned with the interface positions on the electronic components, all connectors are simultaneously inserted into the interfaces.

[0036] See Figure 2 and Figure 3 The guiding mechanism 4 includes a guide rail 401 fixedly installed on the inner rear wall of the second junction box 3. A groove is provided on the guide rail 401, and several slide blocks 402 are slidably installed within the groove. A guide roller 403 is fixedly installed on the front surface of each slide block 402. A locking bolt 404 is threadedly connected to the front end surface of the guide roller 403. One end of the locking bolt 404 movably passes through the guide roller 403 and the slide block 402, and movably abuts against the inner rear wall of the groove. The slide block 402 slides within the groove on the guide rail 401. The position of the guide roller 403 is adjusted to align with the electronic component according to its specific location. Then, the locking bolt 404 is rotated so that its end abuts against the inner rear wall of the groove, thus fixing the slide block 402. After the wire is placed in the first junction box 2 and the second junction box 3, the wire is sleeved on the surface of the guide roller 403.

[0037] See Figure 3 and Figure 6The winding mechanism 6 includes a connecting ring 601 movably mounted on the surface of the winding tube 5. The surface of the winding tube 5 has multiple limiting grooves. Multiple first limiting blocks 9 are fixedly mounted on the inner ring of the connecting ring 601. The first limiting blocks 9 are movably mounted in adjacent limiting grooves, enabling them to limit the rotation of the connecting ring 601. A winding frame 602 is rotatably mounted on the right side wall of the connecting ring 601. The winding frame 602 includes two rotating rings 6021. Four connecting posts 6022, evenly distributed along the circumferential direction, are fixedly mounted between the two rotating rings 6021. The surface of each connecting post 6022 has strip-shaped lead holes 6023. The left end of the rotating ring 6021 has several limiting holes evenly distributed along the circumference of the rotating ring 6021. The upper left side surface of the connecting ring 601 is movably inserted with a limiting pin 603. One end of the limiting pin 603 is movably inserted with the limiting hole on the surface of the rotating ring 6021. A first spring 604 is sleeved on the surface of the limiting pin 603. The right end of the first spring 604 is fixedly connected to the connecting ring 601.

[0038] To facilitate wiring during the replacement of electronic components inside the distribution cabinet, the wire connectors pass through the lead-in holes 6023 on the surface of any connecting post 6022 on the winding frame 602, leaving a certain length. This process is repeated for all wire connectors within the same second junction box 3. Then, the winding tube 5 is rotated to wind part of the wire onto the winding frame 602. All wire connectors are then fixed using the positioning mechanism 8. Finally, the positioning mechanism 8 pushes all wire connectors into the corresponding electronic component interfaces above for power connection. After completion, the mechanism is pulled... The limiting pin 603 on the connecting ring 601 releases the limiting pin 603 from the winding frame 602, allowing the winding frame 602 to rotate relative to the connecting ring 601. At this time, the rotation of the winding frame 602 can individually bundle the wires at that position, ensuring that the wires at that position are in a straight state. Furthermore, when electronic components need to be replaced later, the wires originally wound on the winding frame 602 can be released by rotating the winding frame 602 in the opposite direction, allowing the wires at one end of the wire connector to be lengthened, thereby facilitating the connection of the connector with the subsequently replaced electronic components.

[0039] See Figure 3 , Figure 5 and Figure 7The internal support mechanism 7 includes multiple top support blocks 701. The surface of the winding tube 5 has sliding holes distributed along the circumference of the winding tube 5. The top support blocks 701 are slidably installed in the sliding holes, and the multiple sliding holes and multiple limiting grooves are staggered. Connecting blocks 702 are fixedly installed inside both the left and right ends of the winding tube 5. Multiple second springs 703 are fixedly connected to the outer wall of the connecting blocks 702. The end of the second spring 703 away from the connecting block 702 is fixedly connected to the top support block 701. Two connecting blocks... A rotating shaft 704 is rotatably connected between the left and right sides of 702 that are close to each other. A pressing roller 705 is fixedly installed on the rotating shaft 704. Multiple inclined surfaces 7051 are installed on the surface of the pressing roller 705. The end of the top support block 701 near the pressing roller 705 moves and abuts against the inclined surface 7051 that is close to the surface of the pressing roller 705. A worm gear 706 is fixedly installed on the left end of the rotating shaft 704. A worm 707 is rotatably installed on the worm gear 706 on the left outer wall of the second wire box 3.

[0040] To facilitate the alignment of the winding mechanism 6 with electronic components for wire bundling, the connecting ring 601 can be slidably adjusted on the winding tube 5. After all the winding mechanism 6 positions are adjusted, the worm gear 707 is rotated, causing the worm wheel 706 to rotate, which in turn drives the pressing roller 705 on the rotating shaft 704 to rotate. When the pressing roller 705 rotates, the inclined surface 7051 on the pressing roller 705 can press and push the top support block 701 to move during the rotation, so that the top support block 701 moves outward along the sliding hole, so that the top support block 701 can abut against the inner ring of the connecting ring 601, thereby fixing the connecting ring 601.

[0041] See Figure 2 , Figure 3 , Figure 4 , Figure 5 The positioning mechanism 8 includes two insert plates 801. Slots are provided at the upper parts of both the left and right ends of the second wire box 3. The insert plates 801 are movably inserted into the corresponding slots below. A positioning frame 802 is fixedly connected to the upper ends of both insert plates 801. Two symmetrical and flat wire-binding rollers 803 are rotatably mounted inside the positioning frame 802. Torsion springs 804 are fixedly connected to both ends of the two wire-binding rollers 803, and the torsion springs 804 are fixedly connected to the positioning frame 802. Third springs 805 are fixedly installed on the inner walls of both the left and right sides of the second wire box 3. The end of the third spring 805 away from the second wire box 3 is fixedly connected to the lower part of the positioning frame 802. A second limiting block 806 is movably inserted into the upper front inner wall of the slot, and the second limiting block 806 is movably inserted into the front surface of the insert plate 801.

[0042] To facilitate the connection of wires to electronic components, the wire connectors pass through the positioning frame 802, allowing the wires to movably abut against the two wire-binding rollers 803 within the positioning frame 802, thereby positioning the wire connectors. After positioning all connectors, the positioning frame 802 is moved upwards, causing all connectors to move upwards as well, allowing the connectors to be inserted into the interface of the upper electronic component. Then, the second limiting block 806 is inserted into the insertion plate 801, limiting the positioning frame 802. The wire connectors inserted into the electronic component are then fixed to the electronic component using a tool. Finally, the second limiting block 806 is pulled in the opposite direction, releasing it from its limiting position on the insertion plate 801, and resetting to its original position.

[0043] See Figure 2 , Figure 8 , Figure 9 and Figure 10 The first junction box 2 includes a housing 201 fixedly installed on the inner rear wall of the cabinet 1. The front end of the housing 201 is open, and an end cap 202 is embedded in the front end of the housing 201. An isolation plate 203 with a hollow internal structure is movably installed inside the housing 201. Several ventilation holes communicating with the interior are opened on the surface of the isolation plate 203. Air boxes 13 are fixedly installed on the inner walls of the upper left and right sides of the cabinet 1. A piston plate 14 is movably installed inside the air box 13. A drive mechanism 15 is connected to the piston plate 14. An air inlet and an air outlet are opened on the lower part and the front side wall of the air box 13, respectively. A one-way valve is installed in both the air inlet and the air outlet. An air inlet pipe 16 is fixedly installed on the air inlet. The end of the air inlet pipe 16 away from the air box 13 is connected to the upper interior of the isolation plate 203. An air outlet pipe 17 is fixedly installed on the air outlet.

[0044] To improve the operational stability of the wires placed inside the first junction box 2, the high-voltage and low-voltage wires inside the first junction box 2 are separated by the isolation plate 203. At the same time, the drive mechanism 15 drives the piston plate 14 to reciprocate, which generates negative pressure inside the air inlet pipe 16 and the isolation plate 203. This negative pressure causes the air vents on the surface of the isolation plate 203 to draw hot air from around the isolation plate 203 into its interior. The hot air then enters the air box 13 through the air inlet pipe 16 and is discharged through the air outlet pipe 17, thereby achieving the purpose of cooling the interior of the first junction box 2 and enabling the wires placed inside the first junction box 2 to work more stably.

[0045] See Figure 9 , Figure 10 and Figure 11Ventilation openings are provided on the upper left and right side walls of the cabinet 1. Louvers are installed inside the ventilation openings, and dustproof nets 10 are installed at the ports of the ventilation openings inside the cabinet 1. Brush plates 11 with hollow internal structures are rotatably installed on the inner walls of the left and right sides of the cabinet 1. The brush plates 11 are movably installed on the surface of the dustproof nets 10. Multiple air outlets 12 that communicate with the interior of the brush plates 11 are also fixedly installed on the side of the brush plates 11 near the dustproof nets 10. The surface of the brush plates 11 is connected to the interior of the air outlet pipe 17. The drive mechanism 15 includes a guide seat 1501 fixedly connected to the piston plate 14. The guide seat 1501 is slidably mounted on the upper part of the bellows 13. A linkage rod 1502 is hinged to the upper part of the guide seat 1501. A turntable 1503 is hinged to the end of the linkage rod 1502 away from the guide seat 1501. The turntable 1503 is rotatably mounted on the inner wall of the upper end of the cabinet 1. A gear 1504 is fixedly mounted on the end of the brush plate 11 near the turntable 1503. A toothed plate 1505 with an arc structure is fixedly mounted on the outer wall of the turntable 1503. The toothed plate 1505 meshes with the gear 1504. Motors are fixedly installed on both the left and right sides of the upper end of the cabinet 1. The output shaft of the motor is fixedly connected to the adjacent turntable 1503.

[0046] To improve air circulation inside cabinet 1, a motor is periodically activated, driving a turntable 1503 to rotate. This causes the linkage rod 1502 on the turntable 1503 to move the guide seat 1501 up and down along the air box 13. Consequently, the guide seat 1501 moves the piston plate 14 inside the air box 13 up and down. Simultaneously, as the turntable 1503 rotates, the toothed plate 1505 on its outer wall drives the gear 1504 to rotate. When the gear 1504 rotates, it moves the brush plate 11 along the surface of the dustproof net 10 to remove dust. At the same time, the air outlet 17 sprays air through the air outlet 12, improving the dust removal effect of the dustproof net 10. When the toothed plate 1505 separates from the gear 1504, the brush plate 11 returns to its initial position under gravity. A buffer pad is placed on the side of the brush plate 11 closest to the air box 13 to cushion the impact when the brush plate 11 rotates and contacts the air box 13.

[0047] In actual operation, after the wire is guided by the guide mechanism 4, the excess part of the wire is wound around the winding mechanism 6. Then all the wire joints are fixed on the positioning mechanism 8, and the joints are inserted into the interface of the electronic component above them through the positioning mechanism 8. Then the interface is fixed with a tool. After the two ends of the wire are installed in the designated position in the same way, the high-voltage wire is first placed in the housing 201 of the first junction box 2, and then the isolation plate 203 is placed in. Then the low-voltage wire is placed in the housing 201 and the end cover 202 is closed. Then the piston plate 14 in the air box 13 is driven by the drive mechanism 15 to work, which can draw the hot air inside the first junction box 2 and send this part of the air into the brush plate 11, and then spray it out through the air outlet 12. At the same time, the brush plate 11 moves back and forth on the surface of the dustproof net 10 for dust removal with the cooperation of the drive mechanism 15.
