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] The power distribution equipment has power distribution branches, which include conductive busbars. The conductive busbars are generally fixed to the circuit board by bolts, and the circuit board is then fixed to the carrier by bolts. The circuit board needs to be designed with different hole positions and configured with bolts, resulting in a large carrier board area, which is not conducive to the miniaturization design of the power distribution equipment. Utility Model Content

[0003] In view of this, this application provides a branch module and power distribution equipment, which is beneficial to the miniaturization design of power distribution equipment.

[0004] One embodiment of this application provides a branch module for use in power distribution equipment. The branch module includes a support, a circuit board, a conductive busbar, and a connecting assembly. The circuit board includes a body and a locking member. The body has a first side and a second side facing away from each other. The support carries the circuit board and is located on the second side. The locking member is fixedly disposed on the body. The conductive busbar is located on the first side. The connecting assembly includes a first fixing member and a second fixing member. The first fixing member passes through the conductive busbar and abuts against the conductive busbar and the body. A portion of the first fixing member extends beyond the conductive busbar and is fixed to the locking member. The second fixing member passes through the support and is fixed to the support. A portion of the second fixing member extends beyond the support and is fixed to the locking member, thereby fixing the support to the body.

[0005] The first and second fixing members can be fixed to the locking members fixed to the board body respectively, thereby fixing the conductive busbar and the carrier seat to the circuit board respectively. This not only helps to reduce the number of openings on the circuit board for fixing the carrier seat and conductive busbar, but also helps to place the carrier seat and conductive busbar at corresponding positions on both sides of the circuit board. This helps to reduce the area reserved on the circuit board for connecting the carrier seat and conductive busbar, thereby reducing the area of ​​the board body and thus helping to reduce the size of the branch module structure, so as to realize the miniaturization design of the power distribution equipment.

[0006] In some embodiments of this application, both the locking member and the first fixing member are conductive. The locking member is in conductive contact with the plate. The first fixing member is in conductive contact with the conductive busbar. The locking member and the first fixing member are in conductive contact.

[0007] The locking component can work with the first fixing component to fix the conductive busbar to the circuit board, and at the same time, it can also make the conductive busbar electrically connected to the circuit board through the first fixing component and the locking component. This helps to reduce the structure required to assemble the conductive busbar to the circuit board and establish an electrical connection, thereby reducing the structure of the branch module and facilitating the miniaturization design of the power distribution equipment.

[0008] In some embodiments of this application, the plate body is provided with mounting holes. The locking member has a first connecting portion and a second connecting portion. A portion of the first connecting portion abuts against the side of the plate body located on the second side. A portion of the first connecting portion is located within the mounting hole. A first fixing member is connected to the portion of the first connecting portion located within the mounting hole. The second connecting portion is connected to the second fixing member.

[0009] The locking member is connected to the first and second fixing members via a first connecting part and a second connecting part, respectively, to achieve a fixed fit between them. The first connecting part can abut against the side of the plate located on the second side, so that when the first fixing member pushes the conductive busbar against the plate, the locking member can support the plate, which helps to prevent the plate from moving relative to the locking member, thus stabilizing and fixing the plate and the conductive busbar. Furthermore, the first connecting part can extend into the mounting hole to facilitate the alignment of the locking member and the mounting hole, which is beneficial for positioning the locking member on the plate.

[0010] In some embodiments of this application, the locking member has a first connecting portion and a second connecting portion. The first connecting portion is connected to a first fixing member. The second connecting portion is connected to a second fixing member. The second connecting portion abuts against a support seat.

[0011] The locking member is connected to the first fixing member and the second fixing member respectively through the first connecting part and the second connecting part to achieve a fixed fit between them. The second connecting part can abut against the bearing seat, so that the second fixing member can cooperate with the second connecting part to clamp the bearing seat, thereby improving the stability of the fixed bearing seat.

[0012] In some embodiments of this application, the locking member has a first connecting portion and a second connecting portion. The first connecting portion and the first fixing member are threadedly connected. The second connecting portion and the second fixing member are also threadedly connected.

[0013] The locking component is connected to the first and second fixing components via a first connecting part and a second connecting part, respectively, to achieve a fixed fit between them. The first and second fixing components can be fixed to the locking component via a threaded connection, which is simple and easy to operate, and the connection is stable.

[0014] In some embodiments of this application, the first connecting portion and the second connecting portion are located at opposite ends of the locking member. The locking member has threaded holes penetrating the first connecting portion and the second connecting portion. The first fixing member and the second fixing member are respectively threaded to the threaded holes.

[0015] The locking component can be connected to the first and second fixing components with a single threaded hole, which simplifies the structure of the locking component and reduces the size of the first, second, and locking components. This reduces the area of ​​the circuit board and facilitates the miniaturization of power distribution equipment.

[0016] In some embodiments of this application, the support is provided with a positioning groove. At least a portion of the locking member extends into the positioning groove.

[0017] The locking component extends into the positioning groove, which enables the board to be aligned with the carrier. It also facilitates the second fixing component to pass through the carrier and be aligned with the locking component, reducing the assembly difficulty of the circuit board and the carrier.

[0018] In some embodiments of this application, the support base is provided with a positioning post. The plate body is provided with a first alignment hole. The conductive bar is provided with a second alignment hole. The positioning post passes through the first alignment hole and extends to the second alignment hole.

[0019] The support base can simultaneously align the board and the busbar through the positioning posts, which helps to simplify the positioning operation between the support base, the circuit board and the busbar, and also helps to position the support base, the circuit board and the busbar on the same reference, so as to make the overall structure more compact.

[0020] In some embodiments of this application, the support base is provided with a support platform protruding towards the plate. The support platform abuts against the side of the plate located on the second side.

[0021] The support platform protrudes and supports the plate so that at least part of the plate structure is spaced apart from the carrier. The space between part of the plate structure and the carrier facilitates the installation of electrical components on the plate and also helps to reduce the possibility that the second fastener and locking device may not be able to fix the carrier and the circuit board together due to production errors.

[0022] In some embodiments of this application, at least a portion of the projection of the conductive busbar and at least a portion of the projection of the support platform coincide along the distribution direction of the first side and the second side.

[0023] The force exerted by the first fixing member on the conductive busbar is partially transmitted to the support platform and partially to the locking member. The support platform can assist in supporting the conductive busbar, which helps to prevent damage to the plate and the locking member.

[0024] In some embodiments of this application, the support seat is provided with a fastening element. The fastening element is engaged with the edge of the plate.

[0025] By setting up snap fasteners, the stability of the plate body assembled to the bearing seat is improved.

[0026] 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.

[0027] 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

[0039] 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.

[0040] 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.

[0041] The terms “first”, “second”, etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0042] The power distribution equipment has power distribution branches, which include conductive busbars. The conductive busbars are generally fixed to the circuit board by bolts, and the circuit board is then fixed to the carrier by bolts. The circuit board needs to be designed with different hole positions and configured with bolts, resulting in a large carrier board area, which is not conducive to the miniaturization design of the power distribution equipment.

[0043] This application provides a branch module for use in power distribution equipment. The branch module includes a support, a circuit board, a conductive busbar, and a connecting assembly. The circuit board includes a body and a locking member. The body has a first side and a second side facing away from each other. The support carries the circuit board and is located on the second side. The locking member is fixedly disposed on the body. The conductive busbar is located on the first side. The connecting assembly includes a first fixing member and a second fixing member. The first fixing member passes through the conductive busbar and abuts against the body. A portion of the first fixing member extends beyond the conductive busbar and is fixed to the locking member. The second fixing member passes through the support and is fixed to the support. A portion of the second fixing member extends beyond the support and is fixed to the locking member, thereby fixing the support to the body.

[0044] The first and second fixing members can be fixed to the locking members fixed to the board body respectively, thereby fixing the conductive busbar and the carrier seat to the circuit board respectively. This not only helps to reduce the number of openings on the circuit board for fixing the carrier seat and conductive busbar, but also helps to place the carrier seat and conductive busbar at corresponding positions on both sides of the circuit board. This helps to reduce the area reserved on the circuit board for connecting the carrier seat and conductive busbar, thereby reducing the area of ​​the board body and thus helping to reduce the size of the branch module structure, so as to realize the miniaturization design of the power distribution equipment.

[0045] 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.

[0046] 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, can connect to input sources of different polarities, and can connect to multiple electrical loads.

[0047] 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.

[0048] 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.

[0049] See Figure 3 In some embodiments, the branch module 100 includes a carrier 10, a circuit board 20, a busbar 30, and a connecting assembly 40. The busbar 30 is connected to the circuit board 20 and is assembled to the carrier 10 along with the circuit board 20. The connecting assembly 40 securely connects the carrier 10, the circuit board 20, and the busbar 30. It is understood that in some embodiments, the busbar 30 is configured to mount a circuit breaker. The busbar 30 is used to connect an electrical load, and the circuit breaker is used to connect or disconnect a circuit supplying electrical energy to the electrical load. For example, the busbar 30 may be a copper busbar.

[0050] In some embodiments, the circuit board 20 includes a board body 21 and a locking member 22. The board body 21 has a first side 211 and a second side 212 facing away from each other. A support 10 supports the circuit board 20 and is located on the second side 212. The locking member 22 is fixedly disposed on the board body 21. A conductive bus 30 is located on the first side 211. The connecting assembly 40 includes a first fixing member 41 and a second fixing member 42. The first fixing member 41 passes through the conductive bus 30 and abuts against the conductive bus 30 against the board body 21. A portion of the first fixing member 41 extends out of the conductive bus 30 and is fixed to the locking member 22. The second fixing member 42 passes through the support 10 and is fixed to the support 10. A portion of the second fixing member 42 extends out of the support 10 and is fixed to the locking member 22, thereby fixing the support 10 to the board body 21.

[0051] The first fixing member 41 and the second fixing member 42 can be fixed to the locking member 22 fixed to the plate 21 respectively, so that the conductive bus 30 and the carrier seat 10 can be fixed to the circuit board 20 respectively. This is beneficial to reduce the number of openings in the circuit board 20 for fixing the carrier seat 10 and the conductive bus 30, and also to make the positions where the carrier seat 10 and the conductive bus 30 are connected to the circuit board 20 respectively at corresponding positions on both sides of the circuit board 20. This is beneficial to reduce the area of ​​the area reserved in the circuit board 20 for connecting the carrier seat 10 and the conductive bus 30, thereby reducing the area of ​​the plate 21 and further reducing the size of the branch module 100, so as to realize the miniaturization design of the power distribution equipment 200.

[0052] The first fixing member 41 pushes the conductive busbar 30 against the plate 21, which on the one hand fixes the conductive busbar 30 to the plate 21, and on the other hand, in some embodiments, allows the conductive busbar 30 to make direct conductive contact with the circuit board 20 to achieve electrical connection. Furthermore, the first fixing member 41 can press the conductive busbar 30 towards the plate 21, which helps prevent the conductive busbar 30 from becoming loose relative to the circuit board 20 when the circuit breaker is plugged in or unplugged.

[0053] In some embodiments, the locking member 22 is fixed to the plate 21 by welding or bonding, and the connection is stable.

[0054] In some embodiments, both the locking member 22 and the first fixing member 41 are conductive. The locking member 22 is in conductive contact with the plate 21. The first fixing member 41 is in conductive contact with the conductive busbar 30. The locking member 22 and the first fixing member 41 are in conductive contact.

[0055] The locking member 22 can work with the first fixing member 41 to fix the conductive bus 30 to the circuit board 20, and at the same time, it can make the conductive bus 30 electrically connected to the circuit board 20 through the first fixing member 41 and the locking member 22. This helps to reduce the structure required to assemble the conductive bus 30 to the circuit board 20 and establish an electrical connection, thereby reducing the structure of the branch module 100 and facilitating the miniaturization design of the power distribution equipment 200.

[0056] See Figure 4 and Figure 5 In some embodiments, the locking member 22 has a first connecting portion 221 and a second connecting portion 222. The first connecting portion 221 is connected to the first fixing member 41, and the second connecting portion 222 is connected to the second fixing member 42. The locking member 22 is connected to the first fixing member 41 and the second fixing member 42 respectively through the first connecting portion 221 and the second connecting portion 222 to achieve a fixed fit between them.

[0057] In some embodiments, the plate 21 is provided with a mounting hole 213. A portion of the first connecting portion 221 abuts against the side of the plate 21 located on the second side 212. A portion of the first connecting portion 221 is provided in the mounting hole 213. A first fixing member 41 is connected to the portion of the first connecting portion 221 located in the mounting hole 213. The first fixing member 41 abuts against the side of the conductive bus 30 located away from the first side 211.

[0058] The first connecting portion 221 can abut against the side of the plate 21 located on the second side 212, so that when the first fixing member 41 pushes the conductive busbar 30 against the plate 21, the locking member 22 can support the plate 21, which helps to prevent the plate 21 from moving relative to the locking member 22, thereby stabilizing and fixing the plate 21 and the conductive busbar 30. Furthermore, the first connecting portion 221 can extend into the mounting hole 213, so that the locking member 22 and the mounting hole 213 can be aligned, which helps to position the locking member 22 on the plate 21.

[0059] Understandably, in some embodiments, the portion of the first connection 221 located in the mounting hole 213 along the direction from the second side 212 to the first side 211 does not extend beyond the mounting hole 213, which helps to prevent the first connection 221 from lifting the conductive busbar 30 off the plate 21.

[0060] Understandably, in some embodiments, the mounting hole 213 penetrates the first side 211 and the second side 212 of the plate 21. A portion of the first connecting portion 221 can extend into the mounting hole 213 in the direction from the second side 212 to the first side 211 to fix the locking member 22 and the plate 21, while a portion of the first fixing member 41 can extend into the mounting hole 213 in the direction from the first side 211 to the second side 212 to fix it with the locking member 22.

[0061] It is understood that in some embodiments, the portion of the first connecting part 221 located in the assembly hole 213 is embedded in the assembly hole 213, which facilitates the assembly and fixing of the locking member 22 in the assembly hole 213.

[0062] In some embodiments, the second connecting portion 222 abuts against the support seat 10. The second fixing member 42 abuts against the side of the support seat 10 located away from the second side 212.

[0063] The second connecting part 222 can abut against the support seat 10 so that the second fixing member 42 can cooperate with the second connecting part 222 to clamp the support seat 10, thereby improving the stability of fixing the support seat 10.

[0064] In some embodiments, the first connecting portion 221 and the first fixing member 41 are threadedly connected. The second connecting portion 222 and the second fixing member 42 are threadedly connected.

[0065] The first fixing member 41 and the second fixing member 42 can be fixed to the locking member 22 respectively through a threaded connection. The connection method is simple and easy to operate, and the connection is stable.

[0066] In some embodiments, the first connecting portion 221 and the second connecting portion 222 are distributed at opposite ends of the locking member 22. The locking member 22 is provided with threaded holes 223 passing through the first connecting portion 221 and the second connecting portion 222. The first fixing member 41 and the second fixing member 42 are respectively threaded to the threaded holes 223. For example, the locking member 22 may be a double-ended nut, and the first fixing member 41 and the second fixing member 42 may each be a bolt.

[0067] The locking member 22 can be connected to the first fixing member 41 and the second fixing member 42 by setting a threaded hole 223, which helps to simplify the structure of the locking member 22 and thus helps to reduce the size of the first fixing member 41, the second fixing member 42 and the locking member 22, thereby reducing the area of ​​the circuit board 20 and facilitating the miniaturization design of the power distribution equipment 200.

[0068] In some embodiments, the support 10 is provided with a positioning groove 11. At least a portion of the locking member 22 extends into the positioning groove 11.

[0069] The locking member 22 extends into the positioning groove 11, which enables the plate 21 to be aligned with the support seat 10. It also facilitates the second fixing member 42 to pass through the support seat 10 and be aligned with the locking member 22, reducing the assembly difficulty of the circuit board 20 and the support seat 10.

[0070] See Figure 3 , Figure 4 and Figure 6 In some embodiments, the support 10 is provided with a positioning post 12. The plate 21 is provided with a first alignment hole 214. The conductive busbar 30 is provided with a second alignment hole 31. The positioning post 12 passes through the first alignment hole 214 and extends to the second alignment hole 31.

[0071] The support 10 can simultaneously align the plate 21 and the conductive busbar 30 through the positioning post 12, which helps to simplify the positioning operation among the support 10, the circuit board 20 and the conductive busbar 30, and also helps to position the support 10, the circuit board 20 and the conductive busbar 30 on the same reference, so as to make the overall structure more compact.

[0072] In some embodiments, the support base 10 is provided with a support platform 13 protruding toward the plate 21. The support platform 13 abuts against the side of the plate 21 located on the second side 212.

[0073] The support platform 13 protrudes and supports the plate 21 so that at least part of the structure of the plate 21 is spaced apart from the support seat 10. The space between part of the structure of the plate 21 and the support seat 10 facilitates the installation of electrical components on the plate 21 and also helps to reduce the possibility that the second fixing member 42 and the locking member 22 may be affected by production errors in fixing the support seat 10 and the circuit board 20 together.

[0074] Understandably, in some embodiments, the positioning post 12 is provided on the support platform 13 so as to visually protrude the positioning post 12, so as to facilitate the positioning post 12 to be aligned and engaged with the first alignment hole 214 and the second alignment hole 31.

[0075] In some embodiments, at least a portion of the projection of the conductive busbar 30 and at least a portion of the projection of the support platform 13 coincide along the distribution direction of the first side 211 and the second side 212. The force exerted by the first fixing member 41 against the conductive busbar 30 is partially transmitted to the support platform 13 and partially transmitted to the locking member 22. The support platform 13 can assist in supporting the conductive busbar 30, which helps to avoid damage to the plate 21 and the locking member 22.

[0076] See Figure 3 and Figure 6 In some embodiments, the support base 10 is provided with a fastening element 14. The fastening element 14 is engaged with the edge of the plate 21. By providing the fastening element 14, the stability of the plate 21 assembled to the support base 10 is improved.

[0077] Understandably, in some embodiments, the latch 14 is engaged with the edge of the side of the plate 21 located on the first side 211 to prevent the plate 21 from tilting from the second side 212 toward the first side 211, thereby improving the flatness of the first side 211 and the second side 212 and facilitating the assembly of the conductive busbar 30 and other electrical components.

[0078] See Figure 3 and Figure 5 In some embodiments, the support base 10 has a receiving groove 15 on the side opposite to the second side 212. The receiving groove 15 is connected to the positioning groove 11. The second fixing member 42 is disposed in the receiving groove 15. By providing the paper receiving hole groove, it is convenient to hide the second fixing member 42 on the one hand, and convenient to position the second fixing member 42 relative to the support base 10 on the other hand.

[0079] 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.
