[0030] Embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0031] The term "comprising" and its variations as used herein signify open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc., may refer to different or the same objects.

[0032] In some conventional distribution cabinets, the busbar is fixed at the limiting structure of the busbar support. However, due to the influence of installation accuracy, the busbar may twist or deform. Combined with the electrodynamic force when the busbar is energized, a large torque may be generated at the limiting structure of the busbar support, thereby affecting the service life of the busbar.

[0033] This disclosure provides a busbar support assembly and a distribution cabinet. The busbar support assembly includes multiple support members arranged sequentially along a first direction. Each support member extends along a second direction perpendicular to the first direction. Each support member includes alternately arranged reinforcing sections and connecting sections. Limiting portions are provided on opposite sides of the reinforcing sections along the first direction. Corresponding limiting portions on the adjacent sides of two adjacent support members cooperate to fix the busbar. Using this arrangement, the limiting portions on adjacent support members can fix the busbar, thereby maintaining its stability. The reinforcing sections on the support members can withstand large loads and resist the torque of the busbar under assembly and electrodynamic forces, preventing breakage of the support members at the limiting portions, thus improving the service life of the busbar support assembly. The following will describe... Figures 1 to 5 The principles of this disclosure will be described in detail below.

[0034] like Figures 1 to 3 As shown, in the distribution cabinet, busbar 600 supplies power to high-power electrical equipment, thus requiring stable and safe operation. The busbar support assembly 100 secures the busbar 600 within the cabinet body 500, maintaining its positional stability and preventing displacement or shaking during operation or assembly. It also ensures electrical insulation between the busbar 600 and the cabinet body 500, preventing electrical leakage and potential safety hazards to operators. For example, the support 10 can be made of insulating materials (such as plastic or ceramic) to prevent short circuits between busbars 600 or between the busbar 600 and the cabinet body 500, thereby enhancing the safety of the distribution cabinet. Furthermore, the support 10 must possess sufficient mechanical strength and corrosion resistance to ensure a long service life under high loads and complex environments.

[0035] In some embodiments, when there are a large number of busbars 600 in the distribution cabinet, multiple sets of busbar support assemblies 100 can be used. These multiple sets of busbar support assemblies 100 can be arranged at intervals along the extension direction of the busbars 600. In this way, the multiple sets of busbar support assemblies 100 can distribute the load, thereby increasing the stability of the overall structure.

[0036] In this disclosure, the first direction Y, the second direction X, and the third direction Z refer to three mutually perpendicular spatial directions, which can correspond to the three coordinate axes in a Cartesian coordinate system. For example, the first direction Y is the vertical direction, the second direction X is the horizontal direction, and the third direction Z is the longitudinal direction. It should be noted that these three directions are not limited to the Cartesian coordinate system and can also be applied to other types of coordinate systems. This disclosure uses the Cartesian coordinate system as an example to explain in detail the structure and working principle of the busbar support assembly 100.

[0037] like Figures 1 to 3 As shown, the busbar support assembly 100 may include multiple support members 10. The multiple support members 10 are arranged sequentially along a first direction Y. The number of support members 10 can be adjusted according to the number of busbars 600 to adapt to different power distribution requirements. As an example, when there are three groups of busbars 600 (each group may include multiple support members), the busbar support assembly 100 may include four support members 10, thereby providing sufficient support points for the busbars 600. As another example, when there is only one group of busbars 600, the busbar support assembly 100 may include two support members 10, thereby meeting the fixing requirements.

[0038] It should be understood that the figures, values, etc., mentioned above and elsewhere in this disclosure are exemplary and are not intended to limit the scope of this disclosure in any way. Any other suitable figures or values ​​are possible.

[0039] like Figures 1 to 3 As shown, each support member 10 extends along a second direction X perpendicular to the first direction Y. Each support member 10 includes alternately arranged reinforcing sections 11 and connecting sections 12. Figure 1 and Figure 2 As shown, each support member 10 includes five alternating connecting segments 12 and four reinforcing segments 11. Each reinforcing segment 11 has a limiting portion 110 on its opposite side along the first direction Y. For example, the top and bottom surfaces of each reinforcing segment 11 have limiting portions 110. The limiting portions 110 on adjacent support members 10 cooperate to form a clamping structure to fix the busbar 600, thereby maintaining the busbar 600 in a stable position. The reinforcing segments 11 have high mechanical strength, for example, by using larger dimensions or stronger materials. The reinforcing segments 11 can withstand larger loads, thus resisting the torque generated on the busbar 600 during electrodynamic or assembly processes. The limiting portions 110 on the reinforcing segments 11 prevent breakage due to stress concentration, thereby extending the service life of the busbar support assembly 100.

[0040] With this arrangement, the limiting portions 110 on two adjacent support members 10 can fix the busbar 600, thereby keeping the busbar 600 stable. The reinforcing section 11 on the support member 10 can withstand a large load and resist the torque of the busbar 600 under assembly and electrodynamic action, preventing the support member 10 from breaking at the limiting portion 110, thereby improving the service life of the busbar support assembly 100.

[0041] In some embodiments, such as Figure 2 and Figure 3 As shown, the thickness of the reinforcing section 11 along the third direction Z, perpendicular to the first direction Y and the second direction X, is greater than the thickness of the connecting section 12 along the third direction Z. With this arrangement, the longitudinal thickness of the reinforcing section 11 is greater than the longitudinal thickness of the connecting section 12. The increased thickness of the reinforcing section 11 enhances its load-bearing capacity. The reinforcing section 11 can resist the torque generated by the busbar 600 under assembly or electrodynamic forces, thereby improving the structural stability of the support member 10. The connecting section 12 does not directly contact the busbar 600 and bears a smaller load, therefore its longitudinal thickness is thinner. While ensuring its necessary support function, the connecting section 12 can reduce material usage, thereby effectively reducing manufacturing costs.

[0042] In some embodiments, such as Figures 2 to 4 As shown, the limiting portion 110 may include a pair of limiting grooves 111 spaced apart from each other along the second direction X, and a limiting protrusion 112 disposed between the pair of limiting grooves 111. With this arrangement, a pair of busbars 600 can be inserted into corresponding limiting grooves 111 in the pair of limiting grooves 111, thereby fixing the two busbars 600 by one limiting portion 110. Meanwhile, the limiting protrusion 112, located between the pair of limiting grooves 111, maintains an appropriate gap between the pair of busbars 600. This gap allows airflow, thereby improving the heat dissipation performance of the pair of busbars 600.

[0043] As another example, the limiting portion 110 may include a single limiting groove 111. In this way, the support member 10 can secure a single busbar 600 at the reinforcing section 11. For example, an irregularly shaped busbar or a rectangular busbar with a large thickness.

[0044] As another example, the limiting part 110 may also include multiple limiting grooves 111, such as three or four. In this way, the support member 10 can fix multiple busbars 600 at the reinforcing section 11, thereby increasing the installation density of the busbars 600.

[0045] In some embodiments, such as Figures 2 to 4As shown, the limiting part 110 also includes a pair of support parts 113. Each pair of support parts 113 is disposed at the bottom of a corresponding limiting groove 111 within a pair of limiting grooves 111. Each support part 113 can abut against a busbar 600 within the corresponding limiting groove 111. When the busbar 600 is inserted into the limiting groove 111, the support part 113 can space the busbar 600 from the bottom of the corresponding limiting groove 111.

[0046] When manufacturing the support member 10, if the bottom of the limiting groove 111 is connected to the sidewall at a right angle, stress concentration will occur at the connection. In some embodiments, an arc-shaped transition section is provided at the connection between the bottom of the limiting groove 111 and the sidewall. The arc-shaped transition section can improve the structural strength of the connection. When the rectangular busbar 600 is inserted into the limiting groove 111, the support part 113 can make the corners of the busbar 600 avoid the arc-shaped transition section, thereby enhancing the positioning stability of the busbar 600. In this way, not only the structural strength of the limiting groove 111 can be improved, but also the positional stability of the busbar 600 can be improved.

[0047] In some embodiments, such as Figure 3 As shown, the projected shape of the reinforcing segment 11 along the first direction Y is one of an ellipse, a circle, or an arc. In this way, the reinforcing segment 11 and the connecting segment 12 are connected by a gradual transition. The longitudinal thickness of the reinforcing segment 11 is greater in the middle. The longitudinal thickness of the reinforcing segment 11 gradually decreases near the connecting segment 12, maintaining consistency with the longitudinal thickness of the connecting segment 12. This gradual transition not only maintains the structural strength of the reinforcing segment 11 but also prevents it from interfering with the installation of other structures at the point of contact with the connecting segment 12.

[0048] In some embodiments, such as Figure 2 and Figure 4 As shown, the reinforcing section 11 includes a pair of reinforcing portions 114 disposed on opposite sides of the limiting portion 110 along the second direction X. With this arrangement, after the busbar 600 is inserted into the limiting groove 111, the pair of reinforcing portions 114 can provide support along opposite sides of the busbar 600 along the second direction X, thereby enhancing the fixing effect and positional stability of the busbar 600.

[0049] In some embodiments, such as Figure 1 and Figure 5As shown, each support member 10 also includes a first connecting portion 121 disposed on the connecting segment 12. The busbar support assembly 100 also includes a first connector 30. The first connector 30 is connected along a first direction Y to the first connecting portion 121 of the corresponding connecting segment 12 of the plurality of support members 10. With this arrangement, the first connector 30 can provide additional fixing at the connecting segment 12, thereby enhancing the load-bearing capacity of the plurality of support members 10 and enabling them to remain stable under high loads. As an example, when the first connecting portion 121 is located in the middle position of the support member 10, the first connector 30, in cooperation with the first connecting portion 121, can significantly improve the bending resistance of the support member 10 and reduce the risk of deformation due to torque.

[0050] In some embodiments, such as Figure 1 As shown, the busbar support assembly 100 may further include a pair of second connectors 20. Each of the plurality of support members 10 includes a first end and a second end disposed opposite each other along a second direction X. One of the pair of second connectors 20 is attached to the plurality of support members 10 at its first end along the second direction X. The other of the pair of second connectors 20 is attached to the plurality of support members 10 at its second end along the second direction X.

[0051] In other embodiments, the multiple support members 10 can be connected by a snap-fit ​​structure. For example, one of two adjacent support members 10 is provided with a snap-fit, and the other of two adjacent support members 10 is provided with a slot. With this arrangement, the multiple support members 10 can be fixed together without the aid of external connectors.

[0052] In some embodiments, such as Figure 1 As shown, the busbar support assembly 100 also includes a third connector 40. The third connector 40 is disposed on one side of the plurality of support members 10 along the first direction Y. The third connector 40 is connected to a pair of second connectors 20. In this way, the third connector 40 and the pair of second connectors 20 can form a support frame for fixing the plurality of support members 10, thereby improving the positional stability of the plurality of support members 10 in space and the rigidity of the overall structure.

[0053] In some embodiments, such as Figure 1 and Figure 2 As shown, each support member 10 has a pair of second connecting portions 122 at its opposite ends along the second direction X. The pairs of second connecting portions 122 are respectively connected to corresponding second connecting members 20 in a pair of second connecting members 20. As an example, the second connecting members 20 may have multiple mating portions along the first direction Y. The mating portions and second connecting portions 122 may be in the form of threaded holes, allowing the support member 10 to be fixed to the second connecting member 20 using threaded components (such as screws or bolts).

[0054] In some embodiments, such as Figure 1 As shown, the number of mating parts on each second connector 20 is the same as the number of support members 10. For example, when the busbar support assembly 100 includes four support members 10, each second connector 20 includes four mating parts. In this way, installers can more easily find the correct mating positions for installation, reducing installation errors and thus improving assembly efficiency.

[0055] In other embodiments, the number of mating parts on each second connector 20 is greater than the number of support members 10. For example, when the busbar support assembly 100 includes four support members 10, each second connector 20 may have ten mating parts. In this way, installers can adjust the installation height of the support members 10 according to actual needs, increasing the application range and flexibility of the busbar support assembly 100, thereby adapting to installation environments with different height requirements.

[0056] This disclosure also provides a power distribution cabinet. For example... Figure 5 As shown, the distribution cabinet includes a cabinet 500, a busbar 600, and a busbar support assembly 100 of any one of the above. The busbar support assembly 100 is disposed inside the cabinet 500 and connected to the cabinet 500. The busbar 600 is disposed between two adjacent support members 10 of the plurality of support members 10 and connected to the corresponding limiting part 110.

[0057] In the busbar support assembly 100 of the distribution cabinet, a plurality of support members 10 are arranged sequentially along a first direction Y. Each support member 10 extends along a second direction X perpendicular to the first direction Y. Each support member 10 includes alternating reinforcing sections 11 and connecting sections 12. Limiting portions 110 are respectively provided on opposite sides of the reinforcing sections 11 along the first direction Y. The corresponding limiting portions 110 on the adjacent sides of two adjacent support members 10 cooperate to fix the busbar 600. One of the paired second connecting members 20 is adjacent to the first end of the plurality of support members 10 along the second direction X and fixed to the plurality of support members 10. The other of the paired second connecting members 20 is adjacent to the second end of the plurality of support members 10 along the second direction X and fixed to the plurality of support members 10. Using this arrangement, the limiting portions 110 on adjacent support members 10 can fix the busbar 600, thereby maintaining the stability of the busbar 600. The reinforcing section 11 on the support member 10 can withstand a large load and resist the torque of the busbar 600 under assembly and electrodynamic action, thus preventing the support member 10 from breaking at the limiting part 110 and improving the service life of the busbar support assembly 100.

[0058] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
