[0020] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The power distribution cabinet with enclosed busbar according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the power distribution cabinet of the enclosed busbar in this embodiment of the utility model includes a power distribution cabinet body 1, a wire fixing mechanism 2, a main support plate 3, and multiple sets of wire fasteners 4.

[0023] The wiring mechanism 2 is installed inside the power distribution cabinet 1, the main support plate 3 is installed inside the power distribution cabinet 1 and is located at the bottom of the wiring mechanism 2, and two closed busbars 31 are installed on the top of the main support plate 3.

[0024] It should be noted that the main support plate 3 serves as a partition inside the distribution cabinet 1. The upper side of the main support plate is equipped with a wire fixing mechanism 2 and an enclosed busbar 31, which fixes the enclosed busbar 31 neatly and regularly. The bottom of the main support plate can be equipped with the main circuit fuse group and the branch circuit breaker group used by the distribution cabinet to ensure other functions of the distribution cabinet 1.

[0025] The wire fixing mechanism 2 includes an upper support plate 21, four damping shafts 22, four wire fixing frames 23, a vertical top-pressing structure 24, and a horizontal top-pressing structure 25.

[0026] The upper support plate 21 is installed inside the distribution cabinet 1 and is located between two enclosed busbars 31. Four damping shafts 22 are respectively installed at the top and bottom of the upper support plate 21 in pairs. Four cable holders 23 are respectively installed on the corresponding damping shafts 22. The enclosed busbars 31 pass through the corresponding cable holders 23. Four sets of vertical top pressure structures 24 and four sets of horizontal top pressure structures 25 are respectively installed on the corresponding cable holders 23.

[0027] It should be noted that the upper support plate 21 serves as a support structure, with four damping shafts 22 installed at its top and bottom respectively. The damping shafts 22 are connected to corresponding cable holders 23, which fix both sides of the enclosed busbar 31 to ensure the fixation effect of the enclosed busbar 31. At the same time, through the rotational connection of the damping shafts 22, when the enclosed busbar 31 is under maintenance, the cable holder 23 on one side can be released, and the side of the enclosed busbar 31 that is not fixed can be rotated out for maintenance, thus achieving the function of facilitating maintenance.

[0028] The cable holder 23 has a C-shaped structure, which facilitates the entry of the enclosed busbar 31. The cable holder 23 is equipped with a vertical pressing structure 24 and a horizontal pressing structure 25, which fix the enclosed busbar 31 from four directions inside the cable holder 23. The cable holder 23 is located on both sides, allowing most of the enclosed busbar 31 to be exposed, which will not affect its normal heat dissipation. Moreover, no bolts, nuts or other components are needed when fixing it, which makes it easy to disassemble and replace the enclosed busbar 31 later.

[0029] Among them, multiple sets of wire buckles 4 are respectively installed on the inner wall of the power distribution cabinet 1 and located below the main support plate 3.

[0030] It should be noted that multiple wire clips 4 are provided to organize and fix the wires connecting the enclosed busbar 31 and the inside of the distribution cabinet 1. At the same time, guide holes can be opened on both sides of the main support plate 3 and the upper support plate 21 to facilitate the passage of wires and ensure the connection between the components.

[0031] Among them, a protective plate 32 is rotatably installed on the main support plate 3. The top of the protective plate 32 is rotatably connected to the power distribution cabinet 1. The protective plate 32 is located on one side of the upper support plate 21. A reinforcing plate 33 is installed on the protective plate 32 and inserted into the upper support plate 21.

[0032] It should be noted that the protection plate 32 can rotate on the top of the main support plate 3. The protection plate 32 protects the wire fixing mechanism 2 and the enclosed busbar 31, further enhancing the protection of the wire fixing mechanism 2 and the enclosed busbar 31. The protection plate 32 is provided with a reinforcing plate 33 that is inserted into the upper support plate 21 to improve the stability of the protection plate 32 and prevent it from shaking.

[0033] Specifically, during the installation of the enclosed busbar 31, the relevant personnel put the enclosed busbar 31 into the cable fixing frame 23, which is fixed by the vertical top pressing structure 24 and the horizontal top pressing structure 25. Then the protective plate 32 is closed, and the reinforcing plate 33 is inserted into the upper support plate 21 for fixing, thus protecting the cable fixing mechanism 2.

[0034] When inspecting the enclosed busbar 31, select one end, then release the vertical top pressure structure 24 and the horizontal top pressure structure 25, control the other end of the enclosed busbar 31, and rotate it out by the damping shaft 22. Inspect the unfixed end. After the inspection is completed, restore the fixation of the enclosed busbar 31. Repeat the above operation to inspect the other end.

[0035] When it is necessary to disassemble and replace the enclosed busbar 31, open the protective plate 32, release the vertical top pressure structure 24 and the horizontal top pressure structure 25 from fixing the enclosed busbar 31, and then the enclosed busbar 31 can be taken out and replaced.

[0036] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the vertical pressing structure 24 includes an upper pressure plate 241, a first telescopic rod 242, a first spring 243, and a toggle plate 244.

[0037] The upper pressure plate 241 is installed inside the cable holder 23 and is located at the top of the enclosed busbar 31. The first telescopic rod 242 is installed at the top of the upper pressure plate 241 and is connected to the cable holder 23. The first spring 243 is sleeved on the first telescopic rod 242. The actuating plate 244 is installed on one side of the upper pressure plate 241. The cable holder 23 has a movable groove, and the actuating plate 244 passes through the movable groove.

[0038] It should be noted that the upper pressure plate 241 has an L-shaped structure and is connected to the wire frame 23 by the first telescopic rod 242, ensuring that it is connected while not separating from the wire frame 23. The reaction force of the first spring 243 provides the pushing pressure to ensure the pressing and fixing effect of the upper pressure plate 241. The toggle plate 244 facilitates the control of the upper pressure plate 241 and facilitates the subsequent release of the fixing effect on the enclosed busbar 31.

[0039] To clearly illustrate the previous embodiment, in one embodiment of this application, such as Figure 3 As shown, the transverse pressing structure 25 includes a side pressure plate 251, a second telescopic rod 252, and a second spring 253.

[0040] The side pressure plate 251 is installed inside the wire frame 23 and located on one side of the enclosed busbar 31. The second telescopic rod 252 is installed on the side pressure plate 251 and connected to the wire frame 23. The second spring 253 is sleeved on the second telescopic rod 252.

[0041] It is understandable that the side pressure plate 251, together with the second telescopic rod 252 and the second spring 253, achieves the effect of pressing and fixing the closed busbar 31, and its principle is the same as that of the vertical pressing structure 24.

[0042] Specifically, the relevant personnel send the enclosed busbar 31 into the cable holder 23. The first spring 243 pushes the upper pressure plate 241 to squeeze and fix the enclosed busbar 31 from the top and limit its position. At this time, under the control of the second spring 253, the pushing side pressure plate 251 presses and fixes the enclosed busbar 31 from the side, completing the control of its fixation. When it is necessary to release the fixation effect, it is only necessary to move the toggle plate 244 upward to release the fixation of the enclosed busbar 31.

[0043] In one embodiment of this utility model, such as Figure 4 As shown, the thread buckle 4 includes two arc-shaped buckles 41, two rotating blocks 42, two support blocks 43, two shafts 44, and two torsion springs 45.

[0044] Two arc-shaped buckles 41 are respectively set below the main support plate 3, two rotating blocks 42 are respectively set on the corresponding arc-shaped buckles 41, two support blocks 43 are respectively set on the inner wall of the power distribution cabinet 1, two shafts 44 are respectively set on the corresponding support blocks 43 and are rotatably connected to the corresponding rotating blocks 42, two torsion springs 45 are respectively set on the corresponding rotating blocks 42 and sleeved on the shafts 44, and the bottom end of the torsion springs 45 is connected to the support blocks 43.

[0045] Understandably, the shaft 44 ensures the rotation of the rotating block 42 and the arc-shaped buckle 41 on the support block 43. The rotation is controlled by the reaction force of the torsion spring 45, ensuring that the two arc-shaped buckles 41 always remain in the buckled state.

[0046] Specifically, when organizing the wires inside the distribution cabinet 1, the relevant staff will rotate the arc-shaped buckle 41 to both sides to open it, pass the wires through the arc-shaped buckle 41, release the arc-shaped buckle 41, and the torsion spring 45 will push the rotating block 42 to make the arc-shaped buckle 41 close together, so as to organize the wires.

[0047] In summary, the enclosed busbar distribution cabinet of this utility model embodiment can neatly arrange the enclosed busbars, facilitate the removal of the enclosed busbars for maintenance, and enable quick disassembly and replacement, thus avoiding any impact on the use of the enclosed busbar distribution cabinet.
