Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a power distribution cabinet. Background Technology

[0002] A power distribution cabinet is a cabinet that integrates electrical components for power distribution. The function of a power distribution cabinet is to distribute and control power to electrical equipment. In case of overload, short circuit, or leakage in the circuit, the power distribution cabinet can also provide power outage protection. Various electrical devices can be controlled through the power distribution cabinet.

[0003] The front of the distribution cabinet is equipped with an openable door panel, which facilitates the operation of its interior by staff. At the same time, various instruments, switches and indicator lights are also installed on the surface of the distribution cabinet to facilitate observation and data reading. Therefore, the electrical components on the door panel need to be connected to the electrical components inside the distribution cabinet through wires. Currently, the wires inside the distribution cabinet are bundled and fixed with cable ties, which makes the wiring inside the distribution cabinet cumbersome and complicated, and it is not easy to find the corresponding wires. In addition, the irregular connection of wires inside the distribution cabinet causes great inconvenience for later maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a power distribution cabinet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A power distribution cabinet includes a door panel, and the inner side of the door panel is provided with a wiring section and a buffer section;

[0007] The wiring section includes at least one base fixedly connected to the door panel. The base has at least one groove for arranging wires. The base is provided with at least one terminal post, which is located near the groove.

[0008] The buffer section includes a buffer plate that is movably connected to the door panel.

[0009] By setting up cable trays, the arrangement of wires inside the door panel is limited and protected. By setting up a buffer plate on the back of the door panel, the overall door panel can be buffered and protected.

[0010] As a further embodiment of this utility model: the door panel is provided with multiple bases, each base is provided with multiple wire grooves, and each wire groove is provided with at least one terminal block that cooperates with the wire groove on its outer side.

[0011] Each cable tray is fitted with at least one terminal block. The wire passes through the cable tray to a position near the terminal block, where it can then be connected.

[0012] As a further embodiment of this utility model: the wire groove includes a first wire groove, a second wire groove, a third wire groove, a fourth wire groove, and a fifth wire groove disposed on the base. The wire groove has an L-shaped structure, and one end of the wire groove passes through the base and is close to the terminal block.

[0013] In this embodiment, each base is provided with five wire slots, and each wire slot is matched with a terminal block.

[0014] As a further embodiment of this utility model: a protective plate is provided in the wire groove and arranged along the direction of the wire groove. The protective plate is rotatably connected to the wire groove by a positioning rod, and the protective plate has a cross-shaped rotating shaft structure.

[0015] By installing a protective plate inside the cable tray, the wires are laid out in the cable tray during use, and the protective plate isolates the wires from the outside world, thus providing protection for the wires laid out in the cable tray.

[0016] As a further embodiment of this utility model: the upper end of the base is provided with a cover plate, the cover plate is provided with a clearance groove that cooperates with the wire groove, and the base and the cover plate are provided with an isolation and clamping component near the terminal post.

[0017] By installing isolation and clamping components on the base and cover plate, the positive and negative wires of the wires leading out from the wire trough can be separated, and the separated wires can be clamped.

[0018] As a further embodiment of this utility model: the isolation and clamping assembly includes a dividing plate located in the groove and a limiting block slidably connected to the cover plate. The cover plate is provided with a sliding groove, one end of the limiting block is slidably connected to the sliding groove, and the sliding groove is provided with a supporting elastic element for resetting the limiting block. The end of the limiting block away from the sliding groove is located above the groove.

[0019] The cable tray is divided into two parts by a dividing plate for placing positive and negative wires, which improves safety. At the same time, the wires are limited by a limiting block to prevent them from falling out of the cable tray.

[0020] As a further embodiment of this utility model: the end of the wire groove away from the terminal block is opened close to the pivot edge of the door panel, and the door panel is provided with a wire sleeve that cooperates with the wire groove.

[0021] The inner opening of the wire sleeve faces the internal electrical components, and the side opening of the wire sleeve faces the inner side of the distribution cabinet. When the door panel is closed, the wire sleeve contacts the inner wall of the distribution cabinet. The wire sleeve on the inner side of the door panel allows the wire to easily enter the inside of the wire trough. At the same time, the wire sleeve protects the wire and prevents the wire from being pinched at the closing point of the door panel and the distribution cabinet. The wire sleeve limits the wire and, by contacting the inner wall of the distribution cabinet, provides some support to the door panel and prevents one side of the door panel from sinking deep into the interior of the distribution cabinet.

[0022] As a further embodiment of this utility model: the wiring part is located between the door panel and the buffer part, and a buffer reset component and a locking component are provided between the buffer plate and the door panel. The buffer plate is provided with a docking hole for avoiding the wiring post.

[0023] By placing the wiring section between the buffer section and the door panel, the buffer plate of the buffer section can protect the wiring section. At the same time, by setting the mating hole to avoid the terminal block, the buffer plate can be prevented from squeezing the terminal block and preventing damage to the terminal block or the buffer plate.

[0024] As a further embodiment of this utility model: the buffer reset assembly includes at least one buffer elastic element located between the buffer plate and the door panel. Both ends of the buffer elastic element are fixedly connected to the door panel and the buffer plate through mounting grooves. A pressing block is slidably connected to the door panel. The main body of the pressing block is located on the side of the door panel away from the buffer plate. The pressing block is connected to a top rod, and the top rod passes through the door panel and abuts against the inner surface of the buffer plate.

[0025] By setting a buffer elastic element between the door panel and the buffer plate, the impact of the buffer plate can be absorbed when the buffer plate is squeezed towards the door panel. At the same time, a squeezing block is also provided so that the buffer plate can be manually reset after the buffering is completed.

[0026] As a further embodiment of this utility model: the locking assembly includes at least one guide groove on the inner surface of the door panel, a guide rod is slidably connected in the guide groove, the side wall of the door panel is provided with a through hole for avoiding the guide rod, the guide rod is slidably connected in the through hole, a support block is slidably sleeved on the middle part of the guide rod, a reset elastic element is fixedly connected to the outside of the support block, the reset elastic element is sleeved on the outer end of the guide rod, the outer end of the reset elastic element is fixedly connected to the inner side wall of the door panel, a push rod is rotatably connected to the end of the guide rod away from the reset elastic element, and the other end of the push rod is rotatably connected to the door panel through a hinge block.

[0027] When the buffer plate is compressed inward, the pressure of the buffer plate on the push rod causes the push rod to push the guide rod outward, and the limiting block at the outer end of the guide rod is engaged in the slot in the distribution cabinet. This reinforces the limiting block with the distribution cabinet, protects the distribution cabinet from damage, and protects the surrounding personnel.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] 1. This utility model sets up a base and sets up multiple wire grooves on the surface of the base. The wires are placed in the wire grooves, which protect and restrict the wires, making them arranged in an orderly manner. This facilitates the later inspection and maintenance by the staff and also ensures the safety of the wires.

[0030] 2. The buffer spring on the inner side of the buffer plate in this application provides the initial buffering effect. While the buffer plate is compressed inward, the pressure of the buffer plate on the push rod causes the push rod to push the guide rod outward, and the limiting block at the outer end of the guide rod is engaged in the slot in the distribution cabinet, thereby reinforcing the limiting block with the distribution cabinet. When the guide rod pushes the support block outward, it compresses the return spring, further buffering the explosive force on the buffer plate, thus protecting the distribution cabinet from damage and protecting the surrounding personnel. By pressing the squeezing block and causing the top rod to squeeze the buffer plate inward, the limiting block is retracted to the inside of the door panel, facilitating the closing and opening of the door panel.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Please see Figure 1 This utility model provides a power distribution cabinet, including a door panel 1 and a wiring part. The wiring part includes at least one base 2 fixedly connected to the door panel 1. At least one wire groove 7 for arranging wires is opened in the base 2. At least one terminal 4 is provided on the base 2, and the terminal 4 is located near the wire groove 7. Multiple bases 2 are provided on the door panel 1, and multiple wire grooves 7 are provided on each base 2. At least one terminal 4 that cooperates with the wire groove 7 is provided on the outside of each wire groove 7. After each wire groove 7 is cooperated with, at least one terminal 4 is provided. The wires pass through the wire grooves 7 to the position near the terminal 4, and can then be connected to the terminal 4.

[0042] In this embodiment, as Figure 3 , Figure 4 As shown, three sets of terminal blocks 4 are installed in an array on the front of the door panel 1. The terminal blocks 4 are signal light terminal blocks. Each terminal block 4 has a base 2 at its bottom. The wire groove 7 includes a first wire groove 201, a second wire groove 202, a third wire groove 203, a fourth wire groove 204, and a fifth wire groove 205. A cover plate 3 is fixedly installed on the top of the base 2. Five protective plates 8 are hinged to the surface of the cover plate 3 in sequence. The protective plates 8 adopt a cross-shaped pivot structure. Each set of terminal blocks 4 consists of five terminals, which correspond to the openings at the top of the first wire groove 201, the second wire groove 202, the third wire groove 203, the fourth wire groove 204, and the fifth wire groove 205, respectively.

[0043] By laying the wires on the top of the protective plate 8, and then rotating the protective plate 8 upwards, the wires laid on top of the protective plate 8 are rotated to the bottom of the protective plate 8. Then, the wires on the five signal light terminals are arranged and separated by the first wire groove 201, the second wire groove 202, the third wire groove 203, the fourth wire groove 204 and the fifth wire groove 205, which facilitates later inspection and maintenance.

[0044] like Figure 4 and Figure 5 As shown, the cover plate 3 is provided with a clearance groove that cooperates with the wire groove 7. The base 2 and the cover plate 3 are provided with an isolation and clamping assembly near the terminal 4. The isolation and clamping assembly includes a dividing plate 9 located in the wire groove 7 and a limiting block 11 slidably connected to the cover plate 3. The cover plate 3 is provided with a sliding groove 10. One end of the limiting block 11 is slidably connected to the sliding groove 10, and the sliding groove 10 is provided with a supporting elastic member 12 for resetting the limiting block 11. The end of the limiting block 11 away from the sliding groove 10 is located above the wire groove 7. The five dividing plates 9 respectively divide the top of the first wire groove 201, the second wire groove 202, the third wire groove 203, the fourth wire groove 204 and the fifth wire groove 205 into two grooves.

[0045] The top of the wire trough 7 is divided into two areas by the dividing plate 9, thereby separating the wires connected to the signal light terminal 4 and thus distinguishing the two wires. At the same time, the limiting block 11 on the top of the dividing plate 9 limits the wires that are stuck into the two sides of the dividing plate 9 to prevent them from coming off the top of the wire trough 7. The wires are bent at the five bends of the wire trough 7, and then the limiting block 11 is pulled to the side to facilitate the installation and removal of the wires later.

[0046] like Figure 1 and Figure 2 As shown, a wire sleeve 5 is fixedly installed on the inner side of the door panel 1, which is located inside the base 2 and the cover plate 3. The inner end opening of the wire sleeve 5 faces the internal electrical components, and the side opening of the wire sleeve 5 faces the inner side of the distribution cabinet. When the door panel 1 is closed, the wire sleeve 5 contacts the inner wall of the distribution cabinet. Five positioning rods 6 are fixedly installed at equal intervals on the bottom of the wire sleeve 5. The positioning rods 6 are located outside the protection plate 8. One end of the protection plate 8 is movably hinged to the positioning rods 6. The positioning rods 6 are located in the middle of the inlet of the wire trough 7.

[0047] The wire sleeve 5 on the inside of the door panel 1 allows the wires to easily enter the wire trough 7. At the same time, the wire sleeve 5 protects the wires, preventing them from being pinched at the closure between the door panel 1 and the distribution cabinet. The wire sleeve 5 also limits the movement of the wires and makes contact with the inner wall of the distribution cabinet, thus providing some support to the door panel 1 and preventing one side of the door panel 1 from sinking too deep into the distribution cabinet.

[0048] like Figure 6As shown, the door panel 1 of this embodiment is provided with a buffer part, the wiring part is located between the door panel 1 and the buffer part, and a buffer reset component and a locking component are provided between the buffer plate 13 and the door panel 1. The buffer plate 13 is provided with a docking hole 14 for avoiding the wiring post 4.

[0049] like Figure 8 As shown, the buffer reset assembly includes at least one buffer elastic element 19 located between the buffer plate 13 and the door panel 1. Both ends of the buffer elastic element 19 are fixedly connected to the door panel 1 and the buffer plate 13 through the mounting groove 25. A pressing block 23 is slidably connected on the door panel 1. The main body of the pressing block 23 is located on the side of the door panel 1 away from the buffer plate 13. The pressing block 23 is connected to a top rod 20. The top rod 20 passes through the door panel 1 and abuts against the inner surface of the buffer plate 13. A handle 24 is provided on the outer side of the pressing block 23. The handle 24 is fixedly installed on the front of the door panel 1. The buffer plate 13 is located inside the cover plate 3, and the guide groove 22 is flush with the cover plate 3.

[0050] like Figure 7 As shown, the locking assembly includes at least one guide groove 22 on the inner surface of the door panel 1. A guide rod 15 is slidably connected in the guide groove 22. The side wall of the door panel 1 is provided with a through hole for avoiding the guide rod 15. The guide rod 15 is slidably connected in the through hole. A support block 21 is slidably sleeved on the middle part of the guide rod 15. A reset elastic member 18 is fixedly connected to the outside of the support block 21. The reset elastic member 18 is sleeved on the outer end of the guide rod 15. The outer end of the reset elastic member 18 is fixedly connected to the inner side wall of the door panel 1. A push rod 17 is rotatably connected to one end of the guide rod 15 away from the reset elastic member 18. The other end of the push rod 17 is rotatably connected to the door panel 1 through a hinge block 26.

[0051] During operation, if an explosion occurs inside the distribution cabinet, it can easily injure nearby personnel. The buffer plate 13 provided in this application utilizes the buffer elastic element 19 on its inner side to provide initial buffering. As the buffer plate 13 is compressed inward, the push rod 17 is pressed by the buffer plate 13, causing the push rod 17 to push the guide rod 15 outward. This causes the limiting block 16 at the outer end of the guide rod 15 to engage in the slot in the distribution cabinet, thereby reinforcing the limiting block 16 with the distribution cabinet. When the guide rod 15 pushes the support block 21 outward, it compresses the reset elastic element 18, further buffering the explosive force on the buffer plate 13. This protects the distribution cabinet from damage and also protects nearby personnel. By pressing the compression block 23 and using the top rod 20 to compress the buffer plate 13 inward, the limiting block 16 is retracted to the inside of the door panel 1, facilitating the closing and opening of the door panel 1.

[0052] Working principle and usage process of this utility model:

[0053] Open the door panel 1, then insert the wire through the inside of the wire sleeve 5, and pull it out from the opening on one side of the wire sleeve 5 located on the base 2. Lay the pulled-out wire on the surface of the protective plate 8, and then rotate the protective plate 8 upwards to rotate the wire on the surface of the protective plate 8 to the bottom of the protective plate 8 and into the wire groove 7. The wire is arranged and separated by the wire groove 7. Then bend the wire at the bend of the wire groove 7 and press the wire into the bottom of the limiting block 11. The limiting block 11 limits the end of the wire, and the dividing plate 9 isolates the two wires, which facilitates later inspection and maintenance. When replacing and checking the wire, open the limiting block 11, pull the wire out from the bottom of the limiting block 11, and then lift the wire upwards. At the same time, rotate the protective plate 8 downwards to pull out the wire inside the wire groove 7, which facilitates the replacement and checking of the wire.
