Description

Technical Field

[0001] This invention relates to the field of distribution box technology, specifically to a wiring and installation structure for a metal distribution box used in power engineering. Background Technology

[0002] Distribution boxes are electrical equipment characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint, and environmental benefits.

[0003] The vast amount of parameters displayed on the distribution box data typically indicates that the electrical wiring of a low-voltage distribution box requires the assembly of switching equipment, measuring instruments, protective devices, and auxiliary equipment within a closed or semi-closed metal cabinet or panel. During normal operation, the circuit can be connected or disconnected manually or automatically. In case of faults or abnormal operation, protective devices will disconnect the circuit or trigger an alarm. Measuring instruments can display various operating parameters, allow adjustment of certain electrical parameters, and provide alerts or signals for deviations from normal operating conditions.

[0004] Because servers connect to many electronic components, the number of these components and the cables connecting them to the server can become tangled and difficult to distinguish. This makes it difficult to quickly troubleshoot when a server malfunctions, thus delaying troubleshooting efficiency.

[0005] With the gradual improvement of people's safety awareness, the field of safe electricity use has received great attention. Safe electricity use is reflected in many scenarios. Currently, cables are usually fixed using screws and clamps. This fixing method is relatively simple. However, it is generally impossible to fix multiple cables with the aforementioned fixing structure, and the problem of messy wiring still occurs.

[0006] Therefore, we propose a wiring and installation structure for metal distribution boxes used in power engineering. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the existing defects and provide a wiring and arrangement structure for metal distribution boxes in power engineering. This structure can fix and organize the wires, so that the wires are layered and neatly arranged inside the distribution box, avoiding overheating due to wire accumulation, and facilitating identification and rapid maintenance. This can effectively solve the problems in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a wiring installation and organization structure for a metal distribution box in power engineering, comprising a distribution box body, a base frame, a hanging rod, a branch wire fixing device, a wire tightening mechanism, and an extension plate; Distribution box enclosure: The front side has an opening for installing a door; Base frame: There are two base frames that are positioned opposite each other on the left and right sides of the internal cavity of the distribution box. The front side of the base frame is equidistantly distributed with buckles along the vertical direction. The top of the cap has a buttonhole, and the two sides are provided with corresponding snap holes. Hanging rod: It is horizontally set between the base frames on both sides. Both ends of the hanging rod are slidably connected with buckles that can move back and forth. The buckles are engaged with the buckles on the corresponding sides. Branch line fixing device: detachably connected to the mounting pole; The wire tightening mechanism is detachably connected to the mounting rod. Extension plate: It can be detachably connected to the mounting rod. Each extension plate has a plug-in round hole, and a rotatable free wire clip is snapped into the plug-in round hole.

[0009] Furthermore, the buckle includes an end plate, a guide rod, a stop nut, a connecting bolt, a snap-fit ​​plate, an adjusting groove, an elastic plate, an end protrusion, and a limiting side plate; One end of the end plate is provided with a sliding hole, and a longitudinal guide rod is provided in the sliding hole. The middle part of the guide rod passes through the through hole at the end of the hanging rod, and both ends of the guide rod are threaded with a stop nut. The other end of the end plate is threaded with at least two connecting bolts. The snap-fit ​​plate has two horizontally adjustable slots in the middle, through which the middle of the connecting bolt passes. Two elastic plates are fixed to the lower side of the snap-fit ​​plate, with end protrusions fixed to the outer lower ends of the elastic plates. A limiting side plate that fits against the base frame is fixed to the side of the snap-fit ​​plate. The mounting rod and base frame are connected by snap-fit ​​fasteners for easy disassembly. The mounting rod, guided by the guide rod, can slide horizontally relative to the base frame. During installation and maintenance, the fixed wires can be pulled outwards for easy installation and replacement. Furthermore, the wire splitter includes a back plate and side plates. There are two side plates, fixed to opposite ends of the back plate. The overall cross-section of the back plate and side plates is U-shaped. Extension plates are fixed to the ends of the side plates. The distance between the two extension plates is greater than the distance between the two side plates. Vertical limiting rods are fixed to the tops of both side plates. The distance between the two limiting rods is greater than the distance between the two side plates but less than the distance between the two extension plates. The wire splitter secures a bundle of wires consisting of multiple conductors, serving a guiding and organizing function. Multiple wire splitters can also be sequentially snapped together, allowing the various bundles to be layered, preventing confusion in multi-layered bundles and facilitating identification.

[0010] Furthermore, it also includes a magnetic connector, which comprises two magnetic plates. The two magnetic plates are respectively fixed to the corresponding mounting rod and end plate, and the two magnetic plates are aligned front to back. The magnetic plates are used to ensure that the mounting rod and end plate remain bonded together when not in a detection state, maintaining their stability.

[0011] Furthermore, wire dividers are fixed laterally at equal intervals on the lower end of the inner side of the back plate. The wire dividers separate the wires one by one.

[0012] Furthermore, the top of the wire separator has a tightening sleeve, which includes an adjustment groove arranged horizontally on the back plate, and two opposing wire clamps are slidably arranged in the adjustment groove.

[0013] Furthermore, the wire clamp is U-shaped in general, and a coinciding rod is fixed at the front end of the wire clamp. The coinciding rods on the two wire clamps of the same tightening sleeve are staggered and opposite each other. It also includes the locking bolts threaded onto the wire clamps. The entire tightening sleeve is retractable to accommodate different numbers of wire groups. The tightening sleeve is mounted on the wire distributor and can retract the wire bundle. The wire distributor can disperse and arrange the wire bundles side by side. The wire bundles have a retraction effect as they pass through the wire distributor and the tightening sleeve, which saves space and avoids obstructing electrical components. The wire bundles also have a dispersion effect as they pass through the tightening sleeve and the wire distributor, which helps in identifying individual wire bundles.

[0014] Furthermore, the wire tightening mechanism includes a mounting plate, a pre-reserved slot, a seat plate, a rear stop seat, a swing arm, a pressure wheel, and a wire stop ring. The mounting plate has pre-reserved slots evenly distributed in the middle. The seat plate is fixed to the rear side of the mounting plate, and the seat plate is positioned corresponding to the pre-reserved slots. The rear stop seat is fixed to the side of the seat plate, and the rear stop seat has a concave surface. The front side of the mounting plate is rotatably connected to a swing arm corresponding to the pre-reserved slots via a rotating shaft. One end of the swing arm is a hand-pressing end, and the other end is rotatably connected to a pressure wheel. A winding cavity is formed between the pressure wheel and the rear stop seat. A wire stop ring is fixed to the end of the pressure wheel away from the corresponding seat plate. The wire tightening mechanism serves to fix the wire in place. It is secured by the rear stop seat and the pressure wheel. Since the wire is pulled outward along with the mounting rod during maintenance, a certain amount of slack needs to be left on the wire. As the wire is bent and wrapped around the pressure wheel, it has a tightening effect, maintaining a certain tension in the wire harness. The wire tightening mechanism tightens the wire harness, and the wire harness is released during maintenance.

[0015] Furthermore, the free-line clamp includes a first clamping arm, a second clamping arm, a hinge shaft, a clamping block, and an elastic bending plate; The first and second clamping arms have a locking part and a clamping part at each end, respectively. The centers of the locking parts of the first and second clamping arms are rotatably connected by a hinge shaft. Both ends of the locking part are fixed with locking blocks. Receiving grooves are provided on the opposite surfaces of the clamping parts of the first and second clamping arms. Elastic bending plates extending into the receiving grooves are fixed to the clamping parts of the first and second clamping arms, respectively. The distance between the ends of the two elastic bending plates away from the hinge shaft is greater than the distance between the other ends of the two elastic bending plates. The free-form wire clamp is used to fix and guide individual wire harnesses. It can be used with components that have holes for easy disassembly, and the angle is adjustable.

[0016] Furthermore, the mounting rod is a hollow tube with forward-sloping cooling nozzles on both its upper and lower sides. An air inlet pipe connects to the inner cavity of the mounting rod. The distribution box housing contains a built-in fan, and the side walls of the distribution box housing have corresponding heat dissipation holes for the fan. The fan's outlet connects to the main port of a multi-way distributor, and the other branches of the multi-way distributor connect to the inlet end of the air inlet pipe. An air chamber is created within the mounting rod, and the distribution of the mounting rod guides the airflow, dispersing external airflow to various locations within the distribution box housing, achieving accurate and uniform heat dissipation.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The wiring and installation organization structure of the metal distribution box for power engineering has the following advantages: 1. The wiring and installation structure of the metal distribution box used in this power project can fix and organize the wires, so that the wires are layered and neatly arranged inside the distribution box, avoiding the wires from accumulating and overheating, and facilitating identification and quick maintenance. 2. The mounting rod and the base frame are connected by a snap-fit ​​mechanism, which facilitates disassembly. The mounting rod can slide horizontally relative to the base frame under the action of the guide rod. During installation and maintenance, the fixed wires can be pulled outwards for easy installation and replacement. 3. The wire splitter fixer fixes the wire harness group composed of multiple wires, and plays a guiding and sorting role. Multiple wire splitters can also be snapped together in sequence to make the wire harness group layered, avoid the confusion of multi-layered wire harness groups, and facilitate identification. 4. The entire tightening sleeve is retractable, accommodating different numbers of wires in a group. The tightening sleeve is mounted on the wire distributor and can retract the wire bundle. The wire distributor can disperse and arrange the wire bundles side by side. The wire bundles have a shrinking effect as they pass through the wire distributor and the tightening sleeve in sequence, which saves space and avoids obstructing electrical components. The wire bundles also have a dispersing effect as they pass through the tightening sleeve and the wire distributor in sequence, which helps to identify individual wire bundles.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-9This embodiment provides a technical solution: a wiring installation and organization structure for a metal distribution box in power engineering, including a distribution box body 1, a base frame 2, a hanging rod 3, a branch wire fixing device 5, a wire tightening mechanism 6, and an extension plate 7; Distribution box body 1: The front side has an opening for installing a box door; Base frame 2: There are two base frames facing each other on the left and right sides of the inner cavity of the distribution box 1. The front side of the base frame 2 has caps 201 evenly distributed in the vertical direction. The top of the cap 201 has a buttonhole 202 and two oppositely arranged snap holes 203; Hanging rod 3: It is horizontally set between the base frames 2 on both sides. The two ends of the hanging rod 3 are slidably connected with buckles 4 that can move back and forth. The buckles 4 are fastened to the buckle caps 201 on the corresponding side. The buckle 4 includes an end plate 401, a guide rod 402, a stop nut 403, a connecting bolt 404, a snap plate 405, an adjusting groove 406, an elastic plate 407, an end protrusion 408, and a limiting side plate 409. One end of the end plate 401 is provided with a sliding hole, and a longitudinal guide rod 402 is provided in the sliding hole. The middle part of the guide rod 402 passes through the through hole at the end of the hanging rod 3, and both ends of the guide rod 402 are threaded with a stop nut 403. The other end of the end plate 401 is threaded with at least two connecting bolts 404. The snap-fit ​​plate 405 has two horizontally arranged adjustment slots 406 in the middle. The middle of the connecting bolt 404 passes through the corresponding adjustment slots 406. Two elastic plates 407 are fixed on the lower side of the snap-fit ​​plate 405. An end protrusion 408 is fixed on the outer side of the lower end of the elastic plate 407. A limiting side plate 409 that fits against the base frame 2 is fixed on the side of the snap-fit ​​plate 405. The mounting rod 3 and the base frame 2 are connected by the buckle 4 for easy disassembly. The mounting rod 3 can slide horizontally relative to the base frame 2 under the action of the guide rod 402. During installation and maintenance, the fixed wire can be pulled outward for easy installation and replacement. End plate 401 is a plate-shaped component of snap fastener 4, typically used to secure and support other components.

[0022] The guide rod 402 is used for horizontal guidance. Since the guide rod 402 is a long axis, it can provide a certain travel space for the mounting rod 3, so that the mounting rod 3 can move horizontally perpendicular to the back of the distribution box 1. The stop nut 403 is a special nut used to determine the starting and stopping positions of the mounting rod 3. It restricts the movement of the mounting rod 3 by adjusting the thread position. The connecting bolt 404 is the bolt that connects the snap-fit ​​plate 405 and the end plate 401 of the snap-fit ​​4 together; Snap-fit ​​plate 405 is a plate-shaped assembly used for fixing and connecting other structures; The adjusting slot 406 is a long strip-shaped slot used to adjust the position and spacing of the buckle. By sliding other connecting bolts in the slot, the position of the connecting bolt 404 in the adjusting slot 406 can be adjusted according to the width requirements of the distribution box 1, which also facilitates installation. The elastic plate 407 is a thin plate-shaped component with a certain degree of elasticity. When compressed, the distance between the two elastic plates 407 decreases so that it can enter the buckle 201. After release, the end protrusion 408 at the lower end of the elastic plate 407 is locked into the locking hole and cannot be easily detached. The end protrusion 408 is a protruding part of the buckle 4, which cooperates with the buckle hole 203 of the buckle cap 201 to limit the range of movement and position of the elastic plate 407 within the buckle cap 201. It can prevent the elastic plate 407 or the buckle 4 as a whole from falling off the base frame 4. The limiting side plate 409 is a plate-like assembly that secures the latch. It is used to limit the position and range of motion of the latch, ensuring that the latch operates in the correct position. It also includes a magnetic connector, which includes two magnetic plates 9. The two magnetic plates 9 are respectively fixed on the corresponding mounting rod 3 and end plate 401, and the two magnetic plates 9 are corresponding to each other. The magnetic plates 9 are used to keep the mounting rod 3 and end plate 401 bonded together when not in the detection state, so as to maintain the stability of both. Branching fastener 5: Detachably connected to the mounting rod 3; The wire splitter 5 includes a back plate 501 and side plates 502. There are two side plates 502, which are fixed to the two ends of the back plate 501. The overall cross-section of the back plate 501 and the side plates 502 is U-shaped. An extension plate 503 is fixed to the end of the side plate 502. The distance between the two extension plates 503 is greater than the distance between the two side plates 502. A vertical limiting rod 504 is fixed to the top of each side plate 502. The distance between the two limiting rods 504 is greater than the distance between the two side plates 502 and less than the distance between the two extension plates 503. The wire splitter 5 fixes the wire harness group composed of multiple wires, and plays a guiding and sorting role. Multiple wire splitters 5 can also be snapped together in sequence to make each wire harness group layered, avoid the confusion of multi-layer wire harness groups, and facilitate identification. A wire divider 10 is fixed horizontally at equal intervals at the lower end of the inner side of the back panel 501; the wire divider separates the wires one by one. During installation, first install one wire branch fixing device 5 on the hanging rod 3, and then stack wire branch fixing devices on the wire branch fixing device 5 in sequence. A set of wire harnesses is clamped between every two wire branch fixing devices 5. During installation, the back plate 501 of each stacked wire branch fixing device 5 is stuck between the two extension plates 503 of the previous wire branch fixing device. The side plate 502 and the extension plate 503 bend due to their different widths, and the limiting rod 504 is stuck on the outside of the bend. The top of the wire separator 5 has a tightening sleeve, which includes an adjustment groove 11 arranged horizontally on the back plate 501, and two opposing wire clips 12 are slidably arranged in the adjustment groove 11. The wire clamp 12 is U-shaped, and a coinciding rod 13 is fixed at one end of the wire clamp 12 on the front side. The coinciding rods 13 on the two wire clamps 12 of the same tightening sleeve are staggered and opposite each other. It also includes a locking bolt 14 threadedly connected to the wire clamp 12; the entire tightening sleeve is retractable and can adapt to wire groups with different numbers of wires. The tightening sleeve is set on the wire divider 5 and can retract the wire group. The wire divider 5 can disperse and arrange the wire group. When the wire group passes through the wire divider 5 and the tightening sleeve in sequence, it has a shrinking effect, which saves space and avoids obstructing electrical components. When the wire group passes through the tightening sleeve and the wire divider 5 in sequence, it has a dispersing effect, which is helpful for identifying individual wire groups. During installation, the wire harness is passed through the two clamps 12 of the tightening sleeve, and then the two clamps 12 are pushed to slide along the adjusting groove 12 to reduce the distance between the two clamps 12. At the same time, the overlapping rods 13 of the two clamps 12 overlap. When the two clamps 12 hold the wire harness without loosening, the clamps 12 are fixed on the back plate 501 by the locking bolts 14 to prevent them from loosening. The wire tightening mechanism 6 is detachably connected to the mounting rod 3; The wire tightening mechanism 6 includes a mounting plate 601, a pre-drilled slot 602, a seat plate 603, a rear stop seat 604, a swing arm 605, a wire pressing wheel 606, and a wire retaining ring 607. The mounting plate 601 has pre-drilled slots 602 evenly distributed in its center. The seat plate 603 is fixed to the rear side of the mounting plate 601, and the seat plate 603 is positioned corresponding to each pre-drilled slot 602. The rear stop seat 604 is fixed to the side of the seat plate 603, and the rear stop seat 604 has a concave surface. The front side of the mounting plate 601 is rotatably connected to a swing arm 605 corresponding to each pre-drilled slot 602 via a pivot. One end of the swing arm 605 is for hand pressure. One end is rotatably connected to a pressure wheel 606, and a winding cavity is formed between the pressure wheel 606 and the rear stop seat 604. A wire-blocking ring 607 is fixed to the end of the pressure wheel 606 away from the corresponding seat plate 603. The wire tightening mechanism 8 plays the role of fixing the wire and is fixed by the rear stop seat 604 and the pressure wheel 606. At the same time, since the wire is pulled outward with the hanging rod 3 during maintenance, it is necessary to leave a certain amount of slack in the wire. Since the wire is bent and attached to the pressure wheel, it has a tightening effect, keeping the wire harness with a certain tension. The wire harness is tightened by the wire tightening mechanism 8 and released during maintenance. During installation, first press the swing arm 605 to make the swing arm 605 drive the wire pressing wheel 606 and the wire stop ring 607 to swing to the front of the mounting plate 601. Wrap the wire harness around the wire pressing wheel 606 and press to reset the wire pressing wheel 606. At this time, the part of the wire harness wrapped around the wire pressing wheel 606 is bent and is clamped by the wire pressing wheel 606 and the rear stop seat 604. When you need to release the wire harness, just press the swing arm 605. Extension plate 7: It can be detachably connected to the mounting rod 3. Each extension plate 17 has a plug-in round hole, and a rotatable free wire clip 8 is snapped into the plug-in round hole. The free line clamp 8 includes a first clamping arm 801, a second clamping arm 802, a hinge shaft 803, a clamping block 804, and an elastic bending plate 805; The first clamping arm 801 and the second clamping arm 802 have a snap-fit ​​part and a clamping part at their two ends, respectively. The centers of the snap-fit ​​parts of the first clamping arm 801 and the second clamping arm 802 are rotatably connected by a hinge shaft 803. Both ends of the snap-fit ​​part are fixed with a snap-fit ​​block 804. The opposite surfaces of the clamping parts of the first clamping arm 801 and the second clamping arm 802 are provided with receiving grooves. The clamping parts of the first clamping arm 801 and the second clamping arm 802 are respectively fixed with elastic bending plates 805 extending into the receiving grooves. The distance between the ends of the two elastic bending plates 805 away from the hinge shaft 803 is greater than the distance between the other ends of the two elastic bending plates 805. The free wire clip 8 is used to fix and guide individual wire harnesses. It can be used with a component with holes for easy disassembly. The angle is also adjustable. The free wire clip 8 has two states: retracted and clamped wire. Figure 8 The diagram shows a cross-sectional view of the free wire clip 8 installed in the insertion hole of the expansion plate 7 in the state of clamping the wire. In the retracted state, the wire is not clamped, and the angle between the first clamping arm 801 and the second clamping arm 802 is "0". At this time, the clamping part of the free wire clip 8 can pass through the insertion hole of the expansion plate 7. When clamping the wire, the wire needs to be pressed between the two elastic bending plates 805 of the free wire clip 8 so that the wire is clamped in the clamping part of the first clamping arm 801 and the second clamping arm 802. At this time, the angle of the first clamping arm 801 and the second clamping arm 802 increases, and the clamping blocks 804 on both sides move away from each other and flip to clamp at the edge of the insertion hole. At this time, the clamping part of the free wire clip 8 cannot be disengaged from the insertion hole, thus achieving a fixing effect. When disassembling, pull the clamped wire away from the expansion plate 7 so that the wire overcomes the elastic force of the elastic bending plate 805 and disengages from the clamping part of the first clamping arm 801 and the second clamping arm 802. At this time, the clamping part of the free wire clip 8 can also be disengaged from the insertion hole. The mounting rod 3 is a hollow tube. The upper and lower sides of the mounting rod 3 are provided with forward-sloping cooling spray holes 15. The mounting rod 3 is provided with an air inlet pipe 16 that connects to its inner cavity. The distribution box 1 has a built-in fan 17. The side wall of the distribution box 1 is provided with heat dissipation holes corresponding to the fan 17. The air outlet of the fan 17 is connected to the main port of the multi-way distributor 18. The other branches of the multi-way distributor 18 are connected to the inlet end of the air inlet pipe 16 respectively. An air chamber is set inside the mounting rod 3, and the air is guided by the distribution of the mounting rod 3, so that the external airflow is dispersed to various positions of the distribution box 1, achieving accurate and uniform heat dissipation. A controller and temperature sensor can be installed inside the distribution box 1 to control the start and stop of the fan 17. The fan 17 introduces external airflow, which is then distributed to the hollow cavities of different mounting rods 3 by the multi-channel splitter 18. The airflow is sprayed through the oblique cooling nozzles 15 on the mounting rods 3 to different positions inside the distribution box 1, carrying away the heat generated by the wires or electrical components.

[0023] The usage process of the wire wiring installation and organization structure for a metal distribution box in power engineering provided by this invention is as follows: First, fix the two base frames 2 vertically on the left and right sides of the inner cavity of the distribution box 1. Then install the electrical components required in the distribution box. After the electrical components are laid out, install an appropriate number of hanging rods 3 according to the position and gap of the electrical components. Each hanging rod 3 has a buckle 4 at both ends for fastening with the buckle cap 201 of the base frame 2. The wire splitter 5 is used to fix a wire harness consisting of multiple wires. When the wire harness needs to be retracted, a tightening sleeve is added to one side of the wire splitter 5. During installation, one wire splitter 5 is first installed on the mounting rod 3, and then wire splitters are stacked on top of each other. A wire harness is clamped between every two wire splitters 5. During installation, the back plate 501 of each stacked wire splitter 5 is inserted between the two extension plates 503 of the previous wire splitter, and the limiting rod 504 is inserted on the outside of the bend. When there are many wire harnesses in a wire harness group, install wire divider 5 in sequence to further group the wire harnesses; After the wire harness passes through the wire divider 5, it still needs to maintain a certain degree of slack. When no maintenance is required, the wire harness should be tightened so that the wire harness is wrapped between the pressure wheel 606 and the rear stop seat 604 of the wire tightening mechanism 6. For a single or a small number of wires forming a wire harness, it can be clamped by the free wire clip 8. Since the free wire clip 8 can rotate, it can adapt to wire harnesses at different angles. Multiple free wire clips 8 can be used in combination with an expansion board 7 with multiple holes for non-linear wiring. It should be noted that the mounting rod 3 serves as the mounting carrier for the buckle 4, the wire fixing device 5, the wire tightening mechanism 6, and the extension plate 7. However, the buckle 4, the wire fixing device 5, the wire tightening mechanism 6, and the extension plate 7 are not arranged in a fixed manner as shown in the figure. In actual practice, they are used individually or in combination according to the distribution location and requirements of different electrical components in the distribution box.

[0024] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
