It should be noted here that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0036] See Figures 1 to 3 As shown, in this embodiment, the busbar fixing clip 10 includes two clamping components 100 and a plurality of fasteners 200. The clamping component 100 includes a first insulating member 110 and a metal reinforcing member 120. The metal reinforcing member 120 is disposed on one side of the first insulating member 110, and the metal reinforcing member 120 is at least partially embedded in the first insulating member 110.

[0037] The outer shape of the first insulating member 110 is generally a column with a rectangular cross-section. A receiving groove 111 may be provided on one side in the height direction of the first insulating member 110; the metal reinforcing member 120 includes a bottom plate 121 and at least one side plate 122 disposed on one side of the bottom plate 121. The bottom plate 121 is disposed on one side of the first insulating member 110, and the side plate 122 is embedded in the receiving groove 111 on one side of the first insulating member 110. The side plate 122 may be disposed at the edge of the bottom plate 121. When the metal reinforcing member 120 includes one side plate 122, the cross-section of the metal reinforcing member 120 may be L-shaped, and when the metal reinforcing member 120 includes two side plates 122, the cross-section of the metal reinforcing member 120 may be U-shaped. When the side plate 122 is disposed at the edge of the bottom plate 121, the metal reinforcing member 120 can be bent and formed by a sheet metal process, thereby reducing the manufacturing cost of the metal reinforcing member 120 and the busbar fixing clip 10.

[0038] A plurality of first grooves 112 are provided on the side of the first insulating member 110 away from the metal reinforcing member 120. The first grooves 112 are used for clamping the busbar 20. The first grooves 112 may be rectangular grooves, and the plurality of first grooves 112 are arranged at intervals along the length direction of the first insulating member 110. The width direction of the first grooves 112 is the length direction of the first insulating member 110, the depth direction of the first grooves 112 is the height direction of the first insulating member 110, and the length direction of the first grooves 112 is the width direction of the first insulating member 110.

[0039] The busbar fixing clip 10 includes two clamping components 100. The fastener 200 connects the two clamping components 100 opposite to each other in the first groove 112. The busbar 20 can be clamped in the two opposite first grooves 112. The width of the first groove 112 is greater than or equal to the width of the busbar 20, and the depth of the first groove 112 is less than half of the height of the busbar 20, that is, the two first insulating parts 110 are arranged at intervals.

[0040] In the existing busbar fixing clip, when the busbar vibrates after being energized, it is easy for the adjacent insulating parts and between the insulating part and the metal fixing part to shift, which will further cause the vibration of the busbar to intensify, and even deform or shift, affecting the electrical conductivity of the busbar.

[0041] In this embodiment, the busbar fixing clip 10 includes two clamping components 100 and a plurality of fasteners 200. The clamping component 100 includes a first insulating part 110 and a metal reinforcing part 120. The metal reinforcing part 120 includes a bottom plate 121 and at least one side plate 122 arranged on one side of the bottom plate 121. The bottom plate 121 is arranged on one side of the first insulating part 110, and the side plate 122 is embedded in the first insulating part 110. A plurality of first grooves 112 are arranged on the side of the first insulating part 110 away from the metal reinforcing part 120. The first grooves 112 are used to clamp the busbar 20. The fastener 200 connects the two clamping components 100 opposite to each other in the first groove 112. The busbar 20 can be clamped in the two opposite first grooves 112. Since the side plate 122 of the metal reinforcing part 120 is embedded in the first insulating part 110, it is not easy for the metal reinforcing part 120 and the first insulating part 110 to slide relative to each other, and the busbar 20 can be clamped more firmly, thus avoiding the intensification of the vibration of the busbar 20, and even deformation or displacement, affecting the electrical conductivity of the busbar 20.

[0042] In addition, the metal reinforcing part 120 includes a bottom plate 121 and a side plate 122. The side plate 122 is embedded in the first insulating part 110, and the bottom plate 121 is arranged on the outer surface of the first insulating part 110, so as to expose the installation position of the fastener 200, making it easier to install and tighten the fastener 200. At the same time, only part of the metal reinforcing part 120 is embedded in the first insulating part 110, and the influence on the structural strength of the metal reinforcing part 120 is relatively small.

[0043] In some embodiments, at least one clamping assembly 100 includes at least one insulating post 130. For example, among two clamping assemblies 100, one clamping assembly 100 includes an insulating post 130 while the other clamping assembly 100 does not include an insulating post 130. Four insulating posts 130 can be spaced apart in the clamping assembly 100 and are spaced along the length direction of the first insulating member 110. The insulating posts 130 are disposed on the side of the first insulating member 110 away from the metal reinforcing member 120, and the insulating posts 130 are integrally connected to the first insulating member 110. At least two first grooves 112 are provided on opposite sides of each insulating post 130. For example, the width of the insulating post 130 is less than or equal to the width of the first insulating member 110, the first grooves 112 are located on both sides in the length direction of the insulating post 130, and two first grooves 112 are spaced apart on each side of the insulating post 130. That is to say, the busbar fixing clip 10 can clamp at least 16 busbars 20, where 4 busbars 20 are for A-phase power supply, 4 busbars 20 are for B-phase power supply, 4 busbars 20 are for C-phase power supply, and the remaining 4 busbars 20 are for N-phase power supply.

[0044] At least one clamping assembly 100 includes an insulating post 130, and the insulating post 130 is integrally connected to the first insulating member 110, which can reduce the number of components. In addition, the insulating post 130 is integrally connected to the first insulating member 110, which can also reduce the generation of eddy currents and the increase in the temperature of the busbar 20 caused by eddy currents.

[0045] In some embodiments, the fastener 200 includes a bolt 210 and a first nut 220. The rod portion of the bolt 210 passes through two clamping assemblies 100 and is connected to the first nut 220. The bolts 210 are arranged in one-to-one correspondence with the insulating posts 130. The insulating posts 130 have inner holes, and the insulating posts 130 are sleeved on the rod portion of the bolt 210 through their inner holes.

[0046] The two clamping assemblies 100 are connected by the bolt 210 and the first nut 220, with a simple structure and high connection strength.

[0047] In some embodiments, the fastener 200 further includes a second nut 230. The second nut 230 is disposed on the rod portion of the bolt 210. The second nut 230 is located on the side of the first insulating member 110 away from the metal reinforcing member 120 near the head of the bolt 210, and the second nut 230 is located in the inner hole of the insulating post 130.

[0048] When the fastener 200 further includes a second nut 230, the bolt 210, the second nut 230, and one of the clamping assemblies 100 can be pre-assembled into one body and first fixed to the skeleton of the power distribution cabinet. At the same time, the bolt 210 and the second nut 230 can further lock the first insulating member 110 and the metal reinforcing member 120 to prevent relative sliding between the two.

[0049] It should be noted that the fastener 200 may include a bolt 210, a first nut 220, and a second nut 230, but is not limited thereto. The fastener 200 may also include a stud, a first nut 220, a second nut 230, and a third nut. The first nut 220, the second nut 230, and the third nut are all arranged on the stud. The third nut and the first nut 220 are respectively located on both sides of the two clamping assemblies 100, and specifically, it can be determined according to the actual situation. In addition, the second nut 230 may be fixedly arranged on the stud or the second nut 230 may be changed to be fixedly arranged on the boss in the middle of the stud.

[0050] The fastener 200 may include a stud, a first nut 220, a second nut 230, and a third nut. The third nut is installed on the stud, and then the stud is passed through the clamping assembly 100 and the second nut 230 is sunk to the bottom of the inner hole of the insulating column 130. Then, the third nut is tightened to connect the first insulating member 110 and the metal fixing member 120 of the clamping assembly 100, which solves the problem that it is inconvenient to tighten the second nut 230.

[0051] In some embodiments, both of the two clamping assemblies 100 include an insulating column 130.

[0052] Both of the two clamping assemblies 100 include an insulating column 130, that is, the structures of the two clamping assemblies 100 are exactly the same. With such a design, the number of parts can be reduced, thereby reducing the manufacturing cost of the busbar fixing clip 10.

[0053] In some embodiments, the busbar fixing clip 10 further includes a second insulating member 300, and the second insulating member 300 is arranged between the two clamping assemblies 100. The outer shape of the second insulating member 300 is generally a column with a rectangular cross-section. A plurality of second grooves 310 are provided on both sides of the second insulating member 300 opposite to the first insulating member 110. As Figure 4 shown, the second grooves 310 are used to cooperate with the first grooves 112 to clamp the busbar 20. The formation and dimensions of the second grooves 310 may be the same as the shape and dimensions of the first grooves 112. A plurality of second grooves 310 are arranged at intervals along the length direction of the second insulating member 300. The width direction of the second grooves 310 is the length direction of the second insulating member 300, the depth direction of the second grooves 310 is the height direction of the second insulating member 300, and the length direction of the second grooves 310 is the width direction of the second insulating member 300. When the busbar fixing clip 10 includes two clamping assemblies 100 and a second insulating member 300 arranged between the two clamping assemblies 100, the busbar fixing clip 10 can clamp two layers of busbars 20.

[0054] In existing power distribution cabinets, most of the installation methods of the busbars 20 are single-layer arrangements. Different busbar 20 specifications correspond to different current levels. For example, for 1000 A, a busbar 20 with 80×8 (height×width) is used; for 1600 A, a busbar 20 with 80×10 is used; for 2500 A, two busbars 20 with 100×10 are used; for 5000 A, four busbars 20 with 120×10 are used, and the unit is millimeter. The large quantity and various specifications of the busbars 20 lead to a significant increase in production costs.

[0055] In this embodiment, the busbar fixing clamp 10 can clamp two layers of busbars 20. For example, when the existing busbars are arranged in a single layer, generally four busbars 20 with 150×10 are used for 6300 A single-phase. In this embodiment, the busbars 20 are arranged in two layers, and eight busbars 20 with 60×10 can be used for 6300 A single-phase. With the two-layer arrangement of the busbars 20, the number of busbars 20 is large. Multiple busbars 20 can disperse the influence of the electrodynamic force, ensure the dynamic stability of the busbars 20, and then reduce the quantity and specifications of the busbars 20, realize the standardization of the busbar 20 specifications, and reduce the enterprise cost. With the large number of busbars 20 and the large horizontal distance between the busbars 20 of the same phase, the influence of the skin effect can also be reduced, the heat dissipation is increased, the current-carrying capacity is improved, and compared with the single-layer arrangement method of the busbars 20, the quantity of the busbars 20 is reduced by 20%.

[0056] In some embodiments, at least one of the contact surfaces between the insulating column 130 and the second insulating member 300, the contact surface between the second insulating member 300 and the insulating column 130, and the contact surface between the first insulating member 110 and the metal reinforcing member 120 is provided with an anti-slip structure 101, and the anti-slip structure 101 is arranged close to the bolt 210. For example, the contact surface between the first insulating member 110 and the metal reinforcing member 120 is provided with an anti-slip structure 101, and the contact surface between the second insulating member 300 and the insulating column 130 is provided with an anti-slip structure 101. The anti-slip structure 101 is arranged close to the bolt 210. When the fastener 200 presses the metal reinforcing member 120, the first insulating member 110, the insulating column 130, and the second insulating member 300 together, the friction force between the adjacent metal reinforcing member 120 and the first insulating member 110, and between the adjacent insulating column 130 and the second insulating member 300 is greater, and it is more difficult to generate relative sliding.

[0057] In some embodiments, the anti-slip structures 101 are located on opposite sides of the bolts 210. For example, the busbar fixing clip 10 includes 4 bolts 210, and the 4 bolts 210 are arranged at intervals along the length direction of the first insulating member 110. Anti-slip structures 101 are provided on the contact surface between the first insulating member 110 and the metal reinforcing member 120, and the anti-slip structures 101 are provided on both sides of each bolt 210, that is, anti-slip structures 101 are provided on both sides of the bolt holes of the first insulating member 110, and 8 anti-slip structures 101 are arranged at intervals along the length direction of the first insulating member 110. Anti-slip structures 101 are provided on the contact surface between the second insulating member 300 and the metal reinforcing member 120, and the anti-slip structures 101 are provided on both sides of each bolt 210, that is, anti-slip structures 101 are provided on both sides of the bolt holes of the second insulating member 300, and 8 anti-slip structures 101 are arranged at intervals along the length direction of the second insulating member 300.

[0058] The anti-slip structures 101 are located on opposite sides of the bolts 210, and multiple anti-slip structures 101 are arranged at intervals along the length direction of the first insulating member 110 or the second insulating member 300, so that the surface available for arranging the anti-slip structures 101 is larger, the friction between the adjacent insulating columns 130 and the second insulating member 300 is greater, and relative sliding is less likely to occur.

[0059] In some embodiments, the anti-slip structure 101 includes anti-slip grooves, and the length direction of the anti-slip grooves is perpendicular to the arrangement direction of the first grooves 112.

[0060] It should be noted that the anti-slip structure 101 may include anti-slip grooves, but is not limited thereto. The anti-slip structure 101 may also include anti-slip protrusions, which may be determined according to specific circumstances. That is to say, the anti-slip structure 101 can make the contact surfaces between the insulating column 130 and the second insulating member 300, between the second insulating member 300 and the insulating column 130, and between the first insulating member 110 and the metal reinforcing member 120 uneven, so as to increase the friction between the adjacent metal reinforcing member 120 and the first insulating member 110, and between the adjacent insulating column 130 and the second insulating member 300. The specific shape of the anti-slip structure 101 is not limited.

[0061] The anti-slip structure 101 includes anti-slip grooves. The structure of the anti-slip structure 101 is simple, and the anti-slip grooves can make the contact surfaces between the adjacent metal reinforcing member 120 and the first insulating member 110, and between the adjacent insulating column 130 and the second insulating member 300 uneven, so as to increase the friction between the adjacent metal reinforcing member 120 and the first insulating member 110, and between the adjacent insulating column 130 and the second insulating member 300.

[0062] The present application also provides a power distribution cabinet, which includes a busbar fixing clip 10 and a busbar 20, and the busbar 20 is clamped in the busbar fixing clip 10.

[0063] In this embodiment, the power distribution cabinet includes a busbar fixing clip 10. The busbar fixing clip 10 includes two clamping assemblies 100 and a plurality of fasteners 200. The clamping assembly 100 includes a first insulating member 110 and a metal reinforcing member 120. The metal reinforcing member 120 includes a bottom plate 121 and at least one side plate 122 provided on one side of the bottom plate 121. The bottom plate 121 is provided on one side of the first insulating member 110, and the side plate 122 is embedded in the first insulating member 110. A plurality of first grooves 112 are provided on the side of the first insulating member 110 away from the metal reinforcing member 120. The first grooves 112 are used for clamping the busbar 20. The fasteners 200 connect two opposite clamping assemblies 100, and the busbar 20 can be clamped in two opposite first grooves 112. Since the side plate 122 of the metal reinforcing member 120 is embedded in the first insulating member 110, it is not easy for the metal reinforcing member 120 and the first insulating member 110 to slide relative to each other, and the busbar 20 can be clamped more firmly, thereby avoiding the intensification of vibration of the busbar 20, or even deformation or displacement, which affects the electrical conductivity of the busbar 20.
