Abstract
Description
Technical Field
[0001] This application relates to the field of power distribution equipment technology, and more particularly to a branch module and power distribution equipment. Background Technology
[0002] Power distribution equipment includes distribution branches to distribute power output to different branch circuits. Typically, distribution branches have multiple conductor bars for connection to multiple branch circuits. In related technologies, to meet safety requirements, adjacent conductor bars need to maintain sufficient safety clearance, but this increases the size of the branch modules, hindering the miniaturization design of the power distribution equipment and increasing production costs. Utility Model Content
[0003] In view of this, this application provides a branch module and power distribution equipment, which facilitates the miniaturization design of power distribution equipment and also helps to reduce production costs.
[0004] One embodiment of this application provides a branch module for use in power distribution equipment, capable of connecting input sources of different polarities. The branch module includes a circuit board, a busbar assembly, and a support. The circuit board has a first assembly area, a second assembly area, and a through slot. The through slot extends through the circuit board and is at least located between the first and second assembly areas. The busbar assembly includes a first busbar and a second busbar. The first busbar is assembled to the first assembly area. The second busbar is assembled to the second assembly area. The first and second busbars are configured to connect input sources of different polarities. The support has a base and a partition. The circuit board is assembled to the base. The partition is located in the base and passes through the through slot. The wall of the through slot is clamped to the partition. The partition is at least partially located between the first and second busbars.
[0005] By setting through slots in the circuit board and inserting partitions into these slots, a barrier is formed between the first and second conductive busbars, increasing the creepage distance and clearance between them, thus ensuring that the first and second conductive busbars meet safety requirements. The through slots and partitions work together to create a barrier between the first and second conductive busbars, shortening the straight-line distance while maintaining a safe distance. This helps reduce the circuit board area, facilitating miniaturization of power distribution equipment and lowering production costs. Furthermore, the slot walls are clamped to the partitions, which enhance the support for the circuit board. The partitions also strengthen the structural strength of the base, thereby increasing the overall structural strength of the branch module. This reduces the need for redundant reinforcement structures in other locations to ensure structural strength, further facilitating miniaturization of power distribution equipment and lowering production costs.
[0006] In some embodiments of this application, the first direction is defined as the distribution direction of the first assembly area and the second assembly area. The through-slot includes a first sub-slot and a second sub-slot. Both the first and second sub-slots are located between the first and second assembly areas and are spaced apart along the first direction. The first and second assembly areas are separated by the first and second sub-slots. Both the first and second sub-slots are perforated with partitions.
[0007] By setting a first sub-slot and a second sub-slot with intervals to separate the first assembly area and the second assembly area, and by using a partition plate, the creepage distance and electrical clearance between the first conductive busbar and the second conductive busbar can be increased without increasing the distance between the first assembly area and the second assembly area. This helps to reduce the circuit board area while meeting safety requirements, facilitates the miniaturization design of power distribution equipment, and reduces production costs.
[0008] In some embodiments of this application, a second direction is defined as perpendicular to a first direction. The first assembly area and the second assembly area each have a first boundary and a second boundary at opposite ends in the second direction. Each first boundary is located on the same side of the first assembly area and the second assembly area along the second direction. Each second boundary is located on the same side of the first assembly area and the second assembly area along the second direction. Both a first sub-slot and a second sub-slot extend along the second direction. The first sub-slot extends to the first boundary. The second sub-slot extends to the second boundary.
[0009] The first sub-slot and the second sub-slot extend along the second direction to the first boundary and the second boundary, respectively, so that the barrier formed by the through slot and the partition can extend along the second direction to the opposite ends of the first assembly area and the second assembly area, thereby improving the blocking effect, increasing the creepage distance and electrical clearance between the first conductive bus and the second conductive bus, which is beneficial to reducing the area of the circuit board, facilitating the miniaturization design of power distribution equipment, and reducing production costs.
[0010] In some embodiments of this application, along a first direction, the first sub-slot is close to the first assembly area, and the second sub-slot is close to the second assembly area. Furthermore, along the first direction, the projected portions of the first and second sub-slots overlap, and the overlap range satisfies a preset range.
[0011] When current flows between the first and second conductive busbars, it needs to bypass the first and second sub-slots. The overlap between the first and second sub-slots along the first direction meets the preset range, which can increase the tortuosity of the leakage current bypassing the first and second sub-slots. This is beneficial to ensuring that the first and second conductive busbars meet safety requirements when reducing the distance between the first and second assembly areas, and facilitates the miniaturization design of power distribution equipment and reduces production costs.
[0012] In some embodiments of this application, the through slot further includes a third sub-slot and a fourth sub-slot. The third sub-slot is located at a first boundary of the first assembly area. The third sub-slot extends along a first direction to communicate with the first sub-slot. The fourth sub-slot is located at a second boundary of the second assembly area. The fourth sub-slot extends along a first direction to communicate with the second sub-slot.
[0013] By setting up a third and fourth sub-slot, the leakage current is increased to pass through the barrier formed by the through slot and the partition at the first and second boundaries, so as to reduce the distance between the first and second assembly areas, facilitate the miniaturization design of the power distribution equipment, and reduce production costs.
[0014] In some embodiments of this application, the partition includes a first sub-plate, a second sub-plate, a third sub-plate, and a fourth sub-plate. The first sub-plate passes through a first sub-groove. The second sub-plate passes through a second sub-groove. The third sub-plate passes through a third sub-groove. The fourth sub-plate passes through a fourth sub-groove. The first sub-plate and the third sub-plate are connected. The second sub-plate and the fourth sub-plate are connected.
[0015] The first and third sub-boards can form continuous barriers at the first and third sub-slots, and the second and fourth sub-boards can form continuous barriers at the second and fourth sub-slots, so as to force leakage current or breakdown voltage to bypass the barriers formed by the through slots and partitions from the side of the first sub-board toward the second boundary and the side of the second sub-board toward the first boundary. While reducing the distance between the first assembly area and the second assembly area, the first and second conductive busbars meet the safety requirements, which facilitates the miniaturization design of power distribution equipment and reduces production costs.
[0016] In some embodiments of this application, the base is provided with a support portion. The support portion abuts against the circuit board to support the circuit board.
[0017] The base supports the circuit board by setting a support part, which helps to stably clamp the partition with the groove wall, improves the stability of the assembly between the support base and the circuit board, helps to compensate for the reduced structural strength of the circuit board by setting the groove, facilitates the miniaturization design of power distribution equipment, and reduces production costs.
[0018] In some embodiments of this application, the distance between the first assembly area and the second assembly area is defined as L, where L ≥ 19.1 mm. The height of the partition extending beyond the circuit board is defined as H, where H + L ≥ 31.8 mm.
[0019] By limiting the ranges of L and H, the first and second conductive busbars can meet safety requirements.
[0020] In some embodiments of this application, multiple first assembly areas and second assembly areas are provided. Furthermore, a first assembly area and a second assembly area are alternately arranged.
[0021] The alternating arrangement of the first and second assembly areas facilitates the provision of multiple sets of output branch circuits with different polarity input sources by the branch module, which helps to reduce the difficulty of circuit connection.
[0022] One embodiment of this application provides a power distribution device. The power distribution device includes a housing, a main wiring module, and branch modules as described in any of the above embodiments. Both the main wiring module and the branch modules are disposed within the housing. The main wiring module and the branch modules are electrically connected.
[0023] Branch modules are electrically connected to the main wiring module to access input sources of different polarities. By incorporating branch modules, power distribution equipment can be miniaturized, reducing production costs. Attached Figure Description

[0036] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0038] The terms “first,” “second,” “third,” etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.
[0039] Power distribution equipment includes distribution branches to distribute power output to different branch circuits. Typically, distribution branches have multiple conductor bars for connection to multiple branch circuits. In related technologies, to meet safety requirements, adjacent conductor bars need to maintain sufficient safety clearance, but this increases the size of the branch modules, hindering the miniaturization design of the power distribution equipment and increasing production costs.
[0040] This application provides a branch module for use in power distribution equipment, capable of connecting input sources of different polarities. The branch module includes a circuit board, a busbar assembly, and a support. The circuit board has a first assembly area, a second assembly area, and a through slot. The through slot extends through the circuit board and is at least located between the first and second assembly areas. The busbar assembly includes a first busbar and a second busbar. The first busbar is assembled to the first assembly area. The second busbar is assembled to the second assembly area. The first and second busbars are configured to connect input sources of different polarities. The support has a base and a partition. The circuit board is assembled to the base. The partition is located in the base and passes through the through slot. The wall of the through slot is clamped to the partition. The partition is at least partially located between the first and second busbars.
[0041] By setting through slots in the circuit board and inserting partitions into these slots, a barrier is formed between the first and second conductive busbars, increasing the creepage distance and clearance between them, thus ensuring that the first and second conductive busbars meet safety requirements. The through slots and partitions work together to create a barrier between the first and second conductive busbars, shortening the straight-line distance while maintaining a safe distance. This helps reduce the circuit board area, facilitating miniaturization of power distribution equipment and lowering production costs. Furthermore, the slot walls are clamped to the partitions, which enhance the support for the circuit board. The partitions also strengthen the structural strength of the base, thereby increasing the overall structural strength of the branch module. This reduces the need for redundant reinforcement structures in other locations to ensure structural strength, further facilitating miniaturization of power distribution equipment and lowering production costs.
[0042] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0043] See Figures 1 to 3 One embodiment of this application provides a branch module 100 and a power distribution device 200. The branch module 100 is applied to the power distribution device 200 and can connect to input sources of different polarities and multiple electrical loads.
[0044] In some embodiments, the power distribution equipment 200 includes a housing 201, a main wiring module 202, and a branch module 100. Both the main wiring module 202 and the branch module 100 are housed within the housing 201. The main wiring module 202 and the branch module 100 are electrically connected.
[0045] The main wiring module 202 connects to input sources of different polarities. The branch module 100 is electrically connected to the main wiring module 202 to connect to input sources of different polarities. The branch module 100 is capable of transmitting electrical energy to each electrical load.
[0046] In some embodiments, the branch module 100 includes a circuit board 10, a busbar group 20, and a carrier 30. The circuit board 10 is mounted to the carrier 30. The busbar group 20 is mounted to the circuit board 10 and configured to connect input sources of different polarities. The carrier 30 carries the circuit board 10 and the busbar group 20 to the housing 201 so that the branch module 100 is mounted within the housing 201.
[0047] See Figures 3 to 5In some embodiments, the circuit board 10 has a first assembly area 11, a second assembly area 12, and a through slot 13. At least one first assembly area 11 and at least one second assembly area 12 are provided. The through slot 13 penetrates the circuit board 10 and is at least located between adjacent first assembly areas 11 and second assembly areas 12. The conductive bus group 20 includes a first conductive bus 21 and a second conductive bus 22. The first conductive bus 21 is assembled to the first assembly area 11. The second conductive bus 22 is assembled to the second assembly area 12. The first conductive bus 21 and the second conductive bus 22 are configured to connect input sources of different polarities. The carrier 30 has a base 31 and a partition 32. The circuit board 10 is assembled to the base 31. The partition 32 is located on the base 31 and has the through slot 13 extending through it. The wall of the through slot 13 is clamped to the partition 32. The partition 32 is at least partially located between the first conductive bus 21 and the second conductive bus 22. The through slot 13 passes through the opposite sides of the circuit board 10; one side of the opposite sides of the circuit board 10 through which the through slot 13 passes is assembled toward the base 31, and the other side is used to assemble the conductive busbar 20.
[0048] By providing a through slot 13 on the circuit board 10 and inserting a partition 32 through the through slot 13, a barrier can be formed between the first conductive bus 21 and the second conductive bus 22, increasing the creepage distance and electrical clearance between them, thereby helping the first conductive bus 21 and the second conductive bus 22 meet safety requirements. Through the cooperation of the through slot 13 and the partition 32, a barrier is formed between the first conductive bus 21 and the second conductive bus 22, ensuring a safe distance while simultaneously shortening the straight-line distance between them. This helps reduce the area of the circuit board 10, facilitating the miniaturization design of the power distribution equipment 200 and reducing production costs. Furthermore, the groove wall of the through groove 13 is clamped to the partition 32, which enhances the support for the circuit board 10. The partition 32 also enhances the structural strength of the base 31, thereby enhancing the overall structural strength of the branch module 100. This helps to reduce the redundant reinforcement support structures set in other positions to ensure the structural strength of the branch module 100, thus facilitating the miniaturization design of the power distribution equipment 200 and reducing production costs.
[0049] In some embodiments, a first direction is defined as parallel to the distribution direction of the first assembly area 11 and the second assembly area 12. A second direction is defined as perpendicular to the first direction. The first direction is parallel to the direction indicated by X in the figure, and the second direction is parallel to the direction indicated by Y in the figure. For ease of reference to the figures, the first direction will be referred to as "first direction X" and the second direction as "second direction Y" in the following text.
[0050] See Figure 3 and Figure 4In some embodiments, the through slot 13 includes a first sub-slot 131 and a second sub-slot 132. Both the first sub-slot 131 and the second sub-slot 132 are located between the first assembly area 11 and the second assembly area 12, and are spaced apart along a first direction X. The first assembly area 11 and the second assembly area 12 are separated by the first sub-slot 131 and the second sub-slot 132. Both the first sub-slot 131 and the second sub-slot 132 are perforated with partitions 32.
[0051] By setting the first sub-slot 131 and the second sub-slot 132 at intervals to separate the first assembly area 11 and the second assembly area 12, and cooperating with the partition 32, the creepage distance and electrical clearance between the first conductive busbar 21 and the second conductive busbar 22 can be increased without increasing the distance between the first assembly area 11 and the second assembly area 12. This is beneficial to reduce the area of the circuit board 10 while meeting safety requirements, facilitates the miniaturization design of the power distribution equipment 200, and reduces production costs.
[0052] In some embodiments, the first assembly area 11 and the second assembly area 12 each have a first boundary 14 and a second boundary 15 at opposite ends in the second direction Y. Each first boundary 14 is located on the same side of the first assembly area 11 and the second assembly area 12 along the second direction Y, and each second boundary 15 is also located on the same side of the first assembly area 11 and the second assembly area 12 along the second direction Y. A first sub-groove 131 and a second sub-groove 132 both extend along the second direction Y. The first sub-groove 131 extends to the first boundary 14. The second sub-groove 132 extends to the second boundary 15.
[0053] The first sub-slot 131 and the second sub-slot 132 extend along the second direction Y to the first boundary 14 and the second boundary 15 respectively, so that the barrier formed by the through slot 13 and the partition 32 can extend along the second direction Y to the opposite ends of the first assembly area 11 and the second assembly area 12, thereby improving the blocking effect, increasing the creepage distance and electrical clearance between the first conductive bus 21 and the second conductive bus 22, which is beneficial to reducing the area of the circuit board 10, facilitating the miniaturization design of the power distribution equipment 200, and reducing production costs.
[0054] Understandably, in some embodiments, the first boundary 14 of the first assembly area 11 and the first boundary 14 of the second assembly area 12 extend substantially along the same straight line in the first direction X, and the second boundary 15 of the first assembly area 11 and the second boundary 15 of the second assembly area 12 extend substantially along the same straight line in the first direction X, so that the two ends of the first assembly area 11 and the second assembly area 12 are substantially flat in the second direction Y, making the first assembly area 11 and the second assembly area 12 more compact as a whole, which facilitates reducing the area of the circuit board 10.
[0055] In some embodiments, between adjacent first assembly areas 11 and second assembly areas 12, along the first direction X, a first sub-slot 131 is close to the first assembly area 11, and a second sub-slot 132 is close to the second assembly area 12; along the second direction Y, the first sub-slot 131 extends to the first boundary 14 of the first assembly area 11, and the second sub-slot 132 extends to the second boundary 15 of the second assembly area 12. Furthermore, along the first direction X, the projected portions of the first sub-slot 131 and the second sub-slot 132 overlap, and the overlap range satisfies a preset range.
[0056] When current flows between the first conductive busbar 21 and the second conductive busbar 22, it needs to bypass the first sub-slot 131 and the second sub-slot 132. The overlap range of the first sub-slot 131 and the second sub-slot 132 along the first direction X meets the preset range, which can increase the tortuosity of the leakage current bypassing the first sub-slot 131 and the second sub-slot 132. This is beneficial to ensuring that the first conductive busbar 21 and the second conductive busbar 22 meet the safety requirements when reducing the distance between the first assembly area 11 and the second assembly area 12, which facilitates the miniaturization design of the power distribution equipment 200 and reduces production costs.
[0057] It is understood that in some embodiments, the specific value of the preset range is related to the voltage between the first conductive busbar 21 and the second conductive busbar 22, etc., so that the creepage distance and electrical clearance between the first conductive busbar 21 and the second conductive busbar 22 meet the safety requirements.
[0058] In some embodiments, the through slot 13 further includes a third sub-slot 133 and a fourth sub-slot 134. The third sub-slot 133 is located at the first boundary 14 of the first assembly area 11. The third sub-slot 133 extends along the first direction X to communicate with the first sub-slot 131. The fourth sub-slot 134 is located at the second boundary 15 of the second assembly area 12. The fourth sub-slot 134 extends along the first direction X to communicate with the second sub-slot 132.
[0059] By setting the third sub-slot 133 and the fourth sub-slot 134, the leakage current is increased to pass through the barrier formed by the through slot 13 and the partition 32 from the first boundary 14 and the second boundary 15, so as to reduce the distance between the first assembly area 11 and the second assembly area 12, facilitate the miniaturization design of the power distribution equipment 200, and reduce production costs.
[0060] See Figure 4 and Figure 5 In some embodiments, the partition 32 includes a first sub-plate 321, a second sub-plate 322, a third sub-plate 323, and a fourth sub-plate 324. The first sub-plate 321 passes through a first sub-groove 131. The second sub-plate 322 passes through a second sub-groove 132. The third sub-plate 323 passes through a third sub-groove 133. The fourth sub-plate 324 passes through a fourth sub-groove 134. The first sub-plate 321 and the third sub-plate 323 are connected. The second sub-plate 322 and the fourth sub-plate 324 are connected.
[0061] The first sub-plate 321 and the third sub-plate 323 can form a continuous barrier at the first sub-slot 131 and the third sub-slot 133, and the second sub-plate 322 and the fourth sub-plate 324 can form a continuous barrier at the second sub-slot 132 and the fourth sub-slot 134, so as to force the leakage current or breakdown voltage to bypass the barrier formed by the through slot 13 and the partition plate 32 from the side of the first sub-plate 321 toward the second boundary 15 and the side of the second sub-plate 322 toward the first boundary 14. While reducing the distance between the first assembly area 11 and the second assembly area 12, the first conductive bus 21 and the second conductive bus 22 meet the safety requirements, which facilitates the miniaturization design of the power distribution equipment 200 and reduces the production cost.
[0062] See Figure 4 and Figure 6 In some embodiments, the distance between the first assembly area 11 and the second assembly area 12 along the first direction X is defined as L, where L ≥ 19.1 mm. The height of the partition 32 extending beyond the circuit board 10 is defined as H, where H + L ≥ 31.8 mm.
[0063] By limiting the ranges of L and H, the first conductive bus 21 and the second conductive bus 22 are made to meet safety requirements.
[0064] For example, L≥19.1mm and H+L≥31.8mm can meet the safety requirements under an alternating voltage of 120V (North American requirement); it is understood that if the system is under other operating conditions, such as an alternating voltage of 220V (Chinese requirement) or 110V (Japanese requirement), the values of L and H can be adjusted accordingly.
[0065] See Figure 4 In some embodiments, multiple first assembly areas 11 and second assembly areas 12 are provided. Furthermore, a first assembly area 11 and a second assembly area 12 are alternately arranged.
[0066] The alternating arrangement of the first assembly area 11 and the second assembly area 12 facilitates the branch module 100 to provide multiple sets of output branch circuits with different polarity input sources, which helps to reduce the difficulty of circuit connection.
[0067] See Figures 3 to 5 In some embodiments, when the first assembly area 11 is provided with second assembly areas 12 on both sides along the first direction X, the first assembly area 11 is provided with first sub-slots 131 on both sides along the first direction X, and the first sub-slots 131 on both sides are connected to the third sub-slot 133 between them. Furthermore, the first sub-plates 321 of the first sub-slots 131 on both sides are connected to the third sub-plates 323 between them, thereby forming a relatively closed area on the side where the first boundary 14 of the first assembly area 11 is located, thereby increasing the creepage distance and electrical clearance between the first conductive bus 21 and the second conductive bus 22.
[0068] When the second assembly area 12 has a first assembly area 11 on both sides along the first direction X, the second assembly area 12 also has a second sub-slot 132 on both sides along the first direction X. The second sub-slots 132 on both sides are connected to the fourth sub-slot 134 between them. The second sub-plates 322 of the second sub-slots 132 on both sides are connected to the fourth sub-plates 324 between them, thereby forming a relatively closed area on the side where the second boundary 15 of the second assembly area 12 is located, so as to increase the creepage distance and electrical clearance between the first conductive bus 21 and the second conductive bus 22.
[0069] In some embodiments, the first sub-grooves 131 located on both sides of the same first assembly area 11 have different extension lengths in the second direction Y, reducing the possibility of bending in the portion of the circuit board 10 where the first assembly area 11 is located, thereby improving the structural stability of the first assembly area 11 of the circuit board 10 relative to other areas of the circuit board 10. Similarly, the second sub-grooves 132 located on both sides of the same second assembly area 12 have different extension lengths in the second direction Y, reducing the possibility of bending in the portion of the circuit board 10 where the second assembly area 12 is located, thereby improving the structural stability of the second assembly area 12 of the circuit board 10 relative to other areas of the circuit board 10.
[0070] See Figure 4 In some embodiments, multiple first conductive bars 21 may be provided in the same first assembly area 11. Multiple second conductive bars 22 may be provided in the same second assembly area 12.
[0071] In some embodiments, both the first conductive bus 21 and the second conductive bus 22 can be copper busbars.
[0072] See Figure 5 and Figure 6 In some embodiments, the base 31 is provided with a support portion 311. The support portion 311 abuts against the circuit board 10 to support the circuit board 10. By providing the support portion 311 to support the circuit board 10, the base 31 helps to stably clamp the partition 32 with the groove wall of the through slot 13, improves the stability of the assembly between the support base 30 and the circuit board 10, helps to compensate for the reduced structural strength of the circuit board 10 due to the through slot 13, facilitates the miniaturization design of the power distribution equipment 200, and reduces production costs.
[0073] In some embodiments, the base 31 and the partition 32 are integrally formed to improve the structural stability of the mounting base.
[0074] See Figure 2 In some embodiments, the power distribution equipment 200 may have multiple branch modules 100. The multiple branch modules 100 are connected to the same main wiring module 202.
[0075] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
