Description

Technical Field

[0001] This invention relates to the field of power engineering technology, specifically to a power cabinet that is easy to maintain. Background Technology

[0002] During the maintenance and repair of electrical engineering projects, it is necessary to regularly maintain the power boxes used for the installation and protection of electronic components. When installing electronic components in existing power boxes, to ensure the cleanliness of the interior, the wires connecting the electronic components and the internal wiring need to be bundled together to improve subsequent maintenance efficiency. There are two main methods for organizing existing wires: one is to cut long wires with a cutter, and the other is to bundle long wires with cable ties. Both methods have significant drawbacks. Firstly, cutting wires with a cutter shortens the wire length, requiring re-splicing with insulating tape when the length needs to be extended. Secondly, bundling with cable ties requires removing the ties with a cutter when the wire length needs to be readjusted, which can easily damage the wires in the middle of the ties. Therefore, we propose a power cabinet that facilitates maintenance. Summary of the Invention

[0005] As a further description of the above technical solution: each of the cable organizers is provided with a mounting base on its rear side. The mounting base includes a positioning frame. Multiple positioning frames are fixedly installed in the inner cavity of the box. A rotating disk is rotatably installed on the front end face of the positioning frame. A positioning plate is fixedly installed on the rear end face of the cable organizer through a prism-shaped positioning rod. The front end of both the positioning frame and the rotating disk is provided with a positioning cavity that matches the outer diameter of the positioning plate. A positioning block that matches the number of side faces of the prism-shaped positioning rod is slidably installed between the positioning frame and the rotating disk.

[0006] As a further description of the above technical solution: the front and rear end faces of the multiple positioning blocks are respectively fixedly installed with sliding shafts and limiting sliders, the front face of the positioning frame is provided with multiple limiting grooves that are slidably engaged with each limiting slider, the front face of the rear end of the rotating disk is provided with multiple arc-shaped grooves that are slidably engaged with each sliding shaft, and the sliding shaft is cylindrical, and the arc-shaped groove is inclined.

[0007] As a further description of the above technical solution: an annular groove is provided around the positioning frame, and an annular slider that slides in cooperation with the annular groove is fixedly installed on the inner wall of the rotating disk. A first connecting block and a second connecting block that are matched in position are fixedly installed inside the annular groove and the annular slider, respectively. A first spring and an arc-shaped telescopic sleeve that are inserted into each other are fixedly installed between the first connecting block and the second connecting block. The first spring is sleeved around the arc-shaped telescopic sleeve.

[0008] As a further description of the above technical solution: the upper and lower ends of the wire are respectively connected to the upper and lower connectors on both sides by electrical connectors. The electrical connector includes an electrical plug and an electrical socket that are connected to each other. The electrical plug is fixedly connected to the outer end of the wire. The electrical socket is opened at the outer end of the connector. A threaded sleeve that rotatably engages with the outer thread of the upper end of the connector is rotatably installed on the periphery of the electrical plug.

[0009] As a further description of the above technical solution: each of the junction boxes is provided with multiple component positioners at equal intervals on its lower side. Each component positioner includes a mounting frame that is fixedly connected to the inner cavity of the box. The electronic components are inserted and installed in the mounting frame. The upper and lower end faces of the electronic components and the upper and lower sides of the inner cavity of the mounting frame are respectively provided with a first positioning groove and a second positioning groove that are aligned with each other. Positioning blocks are inserted and installed in the first positioning groove and the second positioning groove.

[0010] As a further description of the above technical solution: a T-shaped limiting rod that slides and engages with the positioning block is fixedly installed in the first positioning groove, and a second spring sleeved around the T-shaped limiting rod is fixedly installed between the positioning block and the first positioning groove.

[0011] As a further description of the above technical solution: the rear end face of the electronic component has movable slots on the upper and lower sides that are respectively connected to the first positioning slots on both sides, the rear end face of the positioning block has an oblique slot, and an oblique plug rod that matches the oblique slot is inserted into the movable slot.

[0012] This invention provides an improved power cabinet that is easy to maintain, and compared with the prior art, it has the following improvements and advantages:

[0013] Firstly, the device is equipped with a first and a second cable management slot. Through the insertion and connection between these slots and the cable, the cable can be installed into the cable management frame. By rotating the cable management shaft, excess cable length can be wound around the cable within the cable management cavity, shortening the length of the external cable and achieving the desired cable management effect. This avoids cutting the cable and improves the efficiency of cable management. A torsion spring is also included. After the cable is inserted into the first and second cable management slots, the torsion spring's reset effect drives the cable management shaft to rotate, facilitating rapid winding of the cable and further improving cable management efficiency.

[0014] Secondly, a positioning frame is set up, and through the sliding cooperation between the positioning blocks, the positioning frame, and the rotating disk, the rotating disk can drive each positioning block to retract inward or expand outward. Thus, through the snap-fit ​​effect between the positioning blocks and the positioning plate, the cable organizer can be installed and removed at the front end of the positioning frame.

[0015] Thirdly, the insertion and engagement between the electrical plug and the electrical socket, and the threaded engagement between the threaded sleeve and the electrical plug, can position the wire at the outer end of the connector. When the torsion spring pulls the wire through the wire guide shaft, it can prevent the connection between the connector and the wire from becoming loose.

[0016] In summary, the insertion of the wire into the first and second cable management slots allows the wire to be installed into the cable management frame. A torsion spring rotates the cable management shaft, achieving the effect of winding and organizing the wire. The sliding engagement between the positioning block, the positioning frame, and the rotating disc allows the positioning block to retract inwards, facilitating the installation and removal of the cable organizer at the front end of the mounting base. Furthermore, the threaded engagement between the threaded sleeve and the connector improves the stability of the connection between the wire and the connector, preventing the wire from becoming loose.

[0032] To make the technical means, creative features, objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific illustrations. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Please see Figures 1-8 This invention provides a technical solution: a power cabinet that is easy to maintain, comprising a cabinet 1 and multiple electronic components 12. Multiple horizontally arranged junction boxes 11 are fixedly installed at equal intervals inside the cabinet 1. The multiple electronic components 12 are respectively located on the lower side of the junction boxes 11 and are plugged into the inner cavity of the cabinet 1. Connectors 14, symmetrically arranged, are fixedly installed on the lower end of the junction boxes 11 and the upper end face of the electronic components 12, respectively. Wires 13 are plugged into the connection between two connectors 14. A cable organizer 2, which plugs into the inner cavity of the cabinet 1, is provided between the junction boxes 11 and the electronic components 12. The cable organizer 2 includes a cable management frame 21, with a cable management cavity 23 at the front end of the cable management frame 21. A cable management shaft 24 is rotatably installed inside the cable management frame 21. The front end face of the cable management cavity 23 is provided with a cable management... A rotating plate 25 is fixedly connected to the front end of the shaft 24. The front end face of the wire-guiding shaft 24 and the front end face of the wire-guiding cavity 23 are respectively provided with a first wire-guiding groove 26 and a second wire-guiding groove 261. The wire 13 is inserted and installed in the first wire-guiding groove 26 and the second wire-guiding groove 261, and the wire 13 is wound around the outside of the wire-guiding shaft 24. A reset cavity 27 is provided in the wire-guiding frame 21, which is connected to the rear end of the wire-guiding cavity 23. The rear end of the wire-guiding shaft 24 is rotatably installed in the reset cavity 27. A torsion spring 271 is sleeved around the reset cavity 27. A first positioning rod 28 and a second positioning rod 29 are fixedly installed at the front and rear ends of the torsion spring 271, respectively. A first positioning hole 281 is provided around the wire-guiding shaft 24 to be inserted into the first positioning rod 28. A second positioning hole 291 is provided around the reset cavity 27 to be inserted into the second positioning rod 29.

[0034] Specifically, after the electronic component 12 is electrically connected to the junction box 11 through the connection between the wire 13 and the two connectors 14, when it is necessary to tidy up the excess length of the wire 13, the wire management shaft 24 is rotated within the wire management frame 21 by rotating the rotating plate 25. Through the insertion and engagement between the first positioning rod 28 and the first positioning hole 281 and the second positioning rod 29 and the second positioning hole 291, the torsion spring 271 can be deformed, giving it elastic potential energy, and aligning the positions of the first wire management groove 26 and the two second wire management grooves 261 on both sides, allowing the middle part of the wire 13 to be inserted into the first... Within the cable management slots 26 and 261, the rotating plate 25 is released, and under the action of the torsion spring 271 restoring its deformation, the cable management shaft 24 can be driven to rotate in the opposite direction to reset. The cable management shaft 24, rotating in the opposite direction, can wind the wire 13 within the cable management cavity 23, collecting the excess length of the wire 13 into the cable management cavity 23, thus completing the arrangement of the wire 13. When inspecting the inside of the housing 1, this can prevent the excess length of the wire 13 from obstructing the view of the staff. Furthermore, by rotating the cable management shaft 24, the wire 13 wrapped around it can be released, making it easier to rearrange the wire 13.

[0035] In another embodiment of the present invention, each cable organizer 2 is provided with a mounting base 3 on its rear side. The mounting base 3 includes a positioning frame 31. Multiple positioning frames 31 are fixedly installed in the inner cavity of the housing 1. A rotating disk 32 is rotatably mounted on the front end face of the positioning frame 31. A positioning plate 35 is fixedly mounted on the rear end face of the cable organizer 2 through a prism-shaped positioning rod 36. The front ends of both the positioning frame 31 and the rotating disk 32 are provided with positioning cavities 34 that match the outer diameter of the positioning plate 35. Positioning blocks 33 that match the number of side faces of the prism-shaped positioning rod 36 are slidably installed between the positioning frame 31 and the rotating disk 32. Sliding shafts 37 and limiting sliders 38 are fixedly installed on the front and rear end faces of multiple positioning blocks 33, respectively. Multiple limiting sliders 38 are provided on the front end face of the positioning frame 31. The rotating disk 32 has a limit groove 381 for dynamic cooperation. The front end face of the rear end of the rotating disk 32 is provided with multiple arc-shaped grooves 371 that are slidably engaged with each sliding shaft 37. The sliding shaft 37 is cylindrical. The arc-shaped grooves 371 are inclined. The positioning frame 31 has an annular groove 39 on its outer periphery. The inner wall of the rotating disk 32 is fixedly installed with an annular slider 391 that is slidably engaged with the annular groove 39. The annular groove 39 and the annular slider 391 are respectively fixedly installed with a first connecting block 392 and a second connecting block 393 that are matched in position. A first spring 395 and an arc-shaped telescopic sleeve 394 that are inserted into each other are fixedly installed between the first connecting block 392 and the second connecting block 393. The first spring 395 is sleeved on the outer periphery of the arc-shaped telescopic sleeve 394.

[0036] Specifically, during the installation of the cable organizer 2, the rotating disk 32 is rotated at the front end of the positioning frame 31. At the front end of the positioning frame 31, the sliding engagement between the limiting groove 381 and the limiting slider 38 restricts the movement direction of each positioning block 33. This allows the rotating disk 32 to expand outwards through the sliding engagement between the inclined arc-shaped groove 371 and the cylindrical sliding shaft 37. The rotating disk 32 also drives the second connecting block 393 to move accordingly, causing the first spring 395 to deform and acquire elastic potential energy. Subsequently, the cable organizer 2 is inserted and installed into the mounting base. 3. At the front end, the positioning plate 35 is inserted into the front positioning cavity 34 of the positioning frame 31. At this time, the prism-shaped positioning rod 36 and each positioning block 33 are aligned with each other. When the rotating disk 32 is released, under the action of the first spring 395 restoring its deformation, the rotating disk 32 can be driven to rotate in the opposite direction to reset. The rotating disk 32, which rotates in the opposite direction, can once again drive each positioning block 33 to retract inward through the sliding cooperation between the limiting slide groove 381 and the limiting slider 38 and the arc-shaped slide groove 371 and the sliding shaft 37, so that each positioning block 33 fits against the outer surface of the prism-shaped positioning rod 36, achieving the effect of positioning the cable organizer 2 at the front end of the mounting base 3.

[0037] In another embodiment of the present invention, the upper and lower ends of the wire 13 are respectively connected to the upper and lower connectors 14 via electrical connectors 4. The electrical connector 4 includes an electrical plug 43 and an electrical socket 42 that are connected to each other. The electrical plug 43 is fixedly connected to the outer end of the wire 13. The electrical socket 42 is opened at the outer end of the connector 14. A threaded sleeve 44 that is threaded and engaged with the outer periphery of the upper end of the connector 14 is rotatably installed on the periphery of the electrical plug 43.

[0038] Specifically, when connecting the two ends of the wire 13 to the two electrical connectors 4, the two are connected to each other through the insertion and engagement between the electrical socket 42 and the electrical plug 43. When the threaded sleeve 44 contacts the connector 14, the threaded sleeve 44 is rotated, so that the rotating threaded sleeve 44 can drive the electrical plug 43 to move through the thread engagement between it and the outer periphery of the connector 14. This can position the connection between the electrical plug 43 and the electrical socket 42, and prevent the connection between the wire 13 and the connector 14 from becoming loose.

[0039] In another embodiment of the present invention, each junction box 11 is provided with a plurality of component positioners 5 at equal intervals on its lower side. Each component positioner 5 includes a mounting frame 51 fixedly connected to the inner cavity of the housing 1. Electronic components 12 are inserted and installed in the mounting frame 51. The upper and lower end faces of the electronic components 12 and the upper and lower sides of the inner cavity of the mounting frame 51 are respectively provided with a first positioning groove 52 and a second positioning groove 53 that are aligned with each other. Positioning blocks 54 are inserted and installed in the first positioning groove 52 and the second positioning groove 53. A T-shaped limiting rod 55 that slides and engages with the positioning block 54 is fixedly installed in the first positioning groove 52. A second spring 56 that is sleeved around the T-shaped limiting rod 55 is fixedly installed between the positioning block 54 and the first positioning groove 52. Movable grooves 58 that communicate with the first positioning grooves 52 are opened on the upper and lower sides of the rear end face of the electronic components 12. An oblique slot 57 is opened on the rear end face of the positioning block 54. An oblique insertion rod 59 that matches the oblique slot 57 is inserted and installed in the movable groove 58.

[0040] Specifically, when installing the electronic component 12, the angled insertion rod 59 is pressed forward on the rear side of the electronic component 12. Through the insertion effect between the angled insertion rod 59 and the angled slot 57, the positioning block 54 can be driven to retract inward into the first positioning groove 52. Then, the electronic component 12 is inserted into the mounting frame 51. The angled insertion rod 59 is released, and under the action of the second spring 56 restoring its deformation, the positioning block 54 can be driven to move outward, so that the positioning block 54 is simultaneously inserted into the first positioning groove 52 and the second positioning groove 53, thereby achieving the effect of positioning the electronic component 12 in the component locator 5.

[0041] Working principle: When laying and installing electronic components 12 inside the housing 1, pressing the inclined insertion rod 59 and using its insertion effect with the inclined slot 57 can drive the positioning block 54 to move into the first positioning groove 52, so that the electronic components 12 can be inserted into the mounting frame 51. Then, releasing the inclined insertion rod 59, the second spring 56 restores its deformation effect, which can drive the positioning block 54 to move outward, so that the positioning block 54 can be inserted into both the first positioning groove 52 and the second positioning groove 53 at the same time. The electronic components 12 can be positioned in the component positioner 5, thus completing the installation of the electronic components 12.

[0042] After the electronic component 12 is installed, the rotating disk 32 can be rotated at the front end of the positioning frame 31. At the front end of the positioning frame 31, the sliding cooperation between the limiting groove 381 and the limiting slider 38 restricts the movement direction of each positioning block 33. This allows the rotating disk 32 to drive each positioning block 33 to expand outward through the sliding cooperation between the inclined arc-shaped groove 371 and the cylindrical sliding shaft 37. The rotating disk 32 can also drive the second connecting block 393 to move with it, causing the first spring 395 to deform and giving it elastic potential energy. Then, the cable organizer 2 is plugged into and installed on the mounting base. 3. At the front end, the positioning plate 35 is inserted into the front positioning cavity 34 of the positioning frame 31. At this time, the prism-shaped positioning rod 36 and each positioning block 33 are aligned with each other. When the rotating disk 32 is released, under the action of the first spring 395 restoring its deformation, the rotating disk 32 can be driven to rotate in the opposite direction to reset. The rotating disk 32, which rotates in the opposite direction, can once again drive each positioning block 33 to retract inward through the sliding cooperation between the limiting slide groove 381 and the limiting slider 38 and the arc-shaped slide groove 371 and the sliding shaft 37, so that each positioning block 33 fits against the outer surface of the prism-shaped positioning rod 36, thereby achieving the effect of positioning the cable organizer 2 at the front end of the mounting base 3.

[0043] When connecting the two ends of the wire 13 to the two electrical connectors 4, the two are connected to each other through the insertion and engagement between the electrical socket 42 and the electrical plug 43. When the threaded sleeve 44 contacts the connector 14, the threaded sleeve 44 is rotated so that the rotating threaded sleeve 44 can drive the electrical plug 43 to move through the thread engagement between it and the outer periphery of the connector 14. This can position the connection between the electrical plug 43 and the electrical socket 42 and prevent the connection between the wire 13 and the connector 14 from becoming loose.

[0044] After the electronic component 12 is electrically connected to the junction box 11 via the connection between the wire 13 and the two connectors 14, when it is necessary to tidy up the excess length of the wire 13, the wire management shaft 24 is rotated within the wire management frame 21 by rotating the rotating plate 25. Through the insertion and engagement between the first positioning rod 28 and the first positioning hole 281 and the second positioning rod 29 and the second positioning hole 291, the torsion spring 271 can be deformed, giving it elastic potential energy, and aligning the first wire management groove 26 with the two second wire management grooves 261 on both sides, allowing the middle part of the wire 13 to be inserted into the first wire management groove. Within the slot 26 and the second cable management slot 261, the rotating plate 25 is released. Under the action of the torsion spring 271 restoring its deformation, the cable management shaft 24 can be driven to rotate in the opposite direction to reset. The cable management shaft 24, which rotates in the opposite direction, can wind the wire 13 within the cable management cavity 23. Excess length of wire 13 can be collected into the cable management cavity 23, completing the arrangement of the wire 13. When inspecting the inside of the box 1, it can prevent excess length of wire 13 from affecting the staff's vision. Furthermore, by rotating the cable management shaft 24, the wire 13 wrapped around it can be released, making it easier to rearrange the wire 13.
