Description

Technical Field

[0001] This application relates to the field of power distribution equipment technology, and more particularly to an installation component and power distribution equipment. Background Technology

[0002] In power distribution equipment, busbars, as key conductive components, are primarily used for transmitting current. The outer casing of power distribution equipment is generally made of metal, and busbars cannot be directly mounted on the casing. In related technologies, to insulate the busbar from the casing, it is installed inside a plastic casing, and then the plastic casing is installed inside the outer casing. The size of the plastic casing is often much larger than the busbar, occupying space for internal wiring or other device placement. This necessitates adding space for device placement within the plastic casing or the outer casing itself. Furthermore, the large size of the plastic casing also makes fixing and installing the casing and other devices difficult, leading to complex assembly and higher costs for the power distribution equipment. Utility Model Content

[0003] In view of this, this application provides an installation component and a power distribution device that can simplify the structure of the power distribution device, reduce the production cost of the power distribution device, and at the same time meet the insulation requirements between the busbar and the inner shell and the outer shell, respectively.

[0004] On one hand, embodiments of this application provide an installation component applied to power distribution equipment. The power distribution equipment includes a busbar and multiple functional modules electrically connected to the busbar. The installation component includes a housing, an inner housing, a first insulating post, and a second insulating post. The housing has an inner wall for installation. The inner housing is configured to accommodate the multiple functional modules and is disposed within the housing. One end of the first insulating post is fixed to the inner wall for installation, and the other end of the first insulating post is configured to be fixed to the busbar, with a first preset distance between the busbar and the inner wall for installation. The second insulating post is spaced apart from the first insulating post, with one end of the second insulating post fixed to the inner wall for installation and the other end of the second insulating post fixed to the inner housing, with a second preset distance between the inner housing and the inner wall for installation, the second preset distance being greater than the first preset distance.

[0005] By setting a first insulating post to support the busbar, a first preset distance is maintained between the busbar and the inner wall of the outer casing to meet the relevant standards for safe distances related to air insulation. A second insulating post supports the inner casing, creating a second preset distance between the inner casing and the inner wall of the outer casing. This second preset distance is greater than the first preset distance, resulting in a staggered installation structure for the inner casing and busbar. Users can install the busbar and inner casing in layers according to their different heights, improving the problem of interference between the busbar and inner casing during assembly and facilitating user installation. The first and second insulating posts replace the plastic shells used in related technologies, allowing the busbar and inner casing to be fixed using the corresponding first and second insulating posts, eliminating the need for plastic shells. This reduces the steps involved in fixing the busbar and inner casing within the outer casing, simplifying the structure and assembly method of the power distribution equipment, improving assembly efficiency, and reducing production costs.

[0006] In at least one embodiment, the height of the second insulating post is greater than the height of the first insulating post, and the inner shell is located above the busbar. The inner shell has an opening located on the side of the inner shell facing the busbar and directly opposite the busbar. The opening is configured to allow a portion of the functional module to extend out and be electrically connected to the busbar.

[0007] Because the height of the second insulating post is greater than that of the first insulating post, the end of the second insulating post away from the mounting base protrudes from the first insulating post, which allows the inner shell and busbar to be stacked, making the structure of the inner shell and busbar compact and facilitating the connection of functional modules and busbars.

[0008] In at least one embodiment, the inner shell is provided with a first clearance groove, the first clearance groove having a first opening and a first bottom wall opposite each other, the first opening being located on the side of the inner shell away from the mounting inner wall, and the first bottom wall being located on the side of the inner shell close to the mounting inner wall. The mounting assembly also includes an electrical connector, the electrical connector entering the first clearance groove through the first opening and passing through the first bottom wall, and a section of the electrical connector extending out of the first bottom wall being a connecting busbar and a functional module.

[0009] By providing a first clearance groove in the inner shell, with the first opening of the groove located on the side of the inner shell away from the mounting bottom wall, it facilitates the operator to assemble the electrical connector from the side of the inner shell away from the mounting bottom wall (i.e., the outer side of the outer shell body). Furthermore, the first clearance groove allows the electrical connector to be positioned completely within the groove, preventing it from protruding from the outer surface of the inner shell when other components need to be assembled there. This reduces interference between the electrical connector and components on the outer side of the inner shell, and avoids scratching these components.

[0010] In at least one embodiment, the first insulating post includes a first rod and a first fastening part. One end of the first rod is fixedly connected to the inner wall of the mounting, and the other end of the first rod is used to abut against the busbar. The first fastening part is inserted through the busbar, and a section of the first fastening part extending out of the busbar is fixed to the end of the first rod away from the inner wall of the mounting. The end of the first fastening part away from the first rod pushes against the busbar in a direction close to the inner wall of the mounting to prevent the busbar from detaching from the first rod.

[0011] By providing a first fastening part, a detachable connection between the first rod and the busbar is achieved, which facilitates the inspection or replacement of the busbar. Furthermore, the first fastening part extends from the end of the first rod away from the mounting inner wall into the busbar and the first rod, so that the operator can operate the first fastening part from the outside of the housing.

[0012] In at least one embodiment, the second insulating post includes a second rod portion and a second fastening portion. The second rod portion is fixedly connected to the inner wall of the mounting and passes through the inner shell, with one end of the second rod portion away from the inner wall of the mounting located inside the inner shell. The second fastening portion passes through the inner shell from the side of the inner shell away from the inner wall of the mounting and is fixed to the end of the second rod portion away from the inner wall of the mounting. The end of the second fastening portion away from the second rod portion pushes against the inner shell in a direction close to the inner wall of the mounting to prevent the inner shell from detaching from the second rod portion.

[0013] By providing a second fastening part, a detachable connection between the second rod and the inner shell can be achieved, so as to facilitate the maintenance or replacement of the inner shell and the functional modules located in the inner shell. Furthermore, the second fastening part passes through the inner shell and the second rod from the end of the second rod away from the mounting inner wall, that is, the second fastening part can pass through the inner shell and the second rod from the outside of the outer shell, so that the operator can operate the first fastening part from the outside of the outer shell.

[0014] In at least one embodiment, the inner shell is provided with a second clearance groove, the second clearance groove having a second opening and a second bottom wall opposite to each other, the second opening being located on the side of the inner shell away from the mounting inner wall, the second bottom wall being located on the side of the inner shell close to the mounting inner wall, the second fastening part entering the second clearance groove through the second opening and passing through the second bottom wall, and a section of the second fastening part passing through the second bottom wall being fixedly connected to the second rod part.

[0015] By providing a second clearance groove, the second opening of the second clearance groove is located on the side of the inner shell away from the mounting inner wall, so that the operator can operate the second fastening part from the outside of the outer shell. In addition, the second clearance groove can make way for the second fastening part, so that the second fastening part can be completely located in the second clearance groove, so that the second fastening part will not protrude from the outer surface of the inner shell, thereby improving the problem of interference between the second fastening part and the components on the outside of the inner shell, and the problem of easily scratching the components on the outside of the inner shell.

[0016] In at least one embodiment, there are multiple first insulating posts and multiple second insulating posts. The multiple first insulating posts and multiple second insulating posts are divided into two support groups. Each support group includes multiple first insulating posts and multiple second insulating posts. The multiple first insulating posts and multiple second insulating posts in each support group are distributed alternately along a first direction. The two support groups are distributed at intervals along a second direction. The first direction is perpendicular to the second direction.

[0017] By setting multiple first insulating pillars and multiple second insulating pillars, and dividing the multiple first insulating pillars and multiple second insulating pillars into two support groups, the multiple first insulating pillars and multiple second insulating pillars support the inner shell, and the multiple first insulating pillars and multiple second insulating pillars form a support surface, thereby improving the support strength and stability of the first insulating pillars and second insulating pillars for the busbar, the inner shell and the functional modules located in the inner shell.

[0018] In at least one embodiment, multiple inner shells are provided, each inner shell being configured to accommodate a functional module, and at least one second insulating post in each support group is fixedly connected to an inner shell.

[0019] By setting up multiple inner shells, each housing a functional module, modularization of individual functional modules is achieved. When a single functional module is damaged, only the damaged module can be repaired, thus improving the problem that repairing a single functional module can easily affect other functional modules. Furthermore, the multiple inner shells and multiple functional modules form multiple branch modules, the positions of which can be arbitrarily changed, enhancing the flexibility of power distribution equipment.

[0020] In at least one embodiment, each second insulating post is detachably connected to the housing.

[0021] The second insulating post is detachably connected to the outer shell. Depending on the specific number of the inner shell and functional modules, an appropriate number of second insulating posts can be set inside the outer shell to further simplify the redundant structure inside the outer shell.

[0022] On the other hand, this application provides a power distribution device, including the above-mentioned mounting component, functional module and busbar, wherein the functional module is disposed in the inner shell of the mounting component; the busbar is electrically connected to the functional module, and is disposed in the outer shell of the mounting component and connected to the first insulating post of the mounting component.

[0023] By applying the above-mentioned mounting components to power distribution equipment, the first and second insulating posts in the mounting components replace the plastic shell in related technologies. The busbar and inner shell can be fixed by the corresponding first and second insulating posts, which can reduce the steps of fixing the busbar and inner shell to the outer shell, simplify the structure and assembly method of the power distribution equipment, improve assembly efficiency, and thus reduce the production cost of the power distribution equipment.

[0042] 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.

[0043] 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.

[0044] In related technologies, busbars, as key conductive components in power distribution equipment, are primarily used for transmitting current. The outer casing of power distribution equipment is generally made of metal, and busbars cannot be directly mounted on the casing. In related technologies, to insulate the busbar from the casing, it is installed inside a plastic casing, which is then installed inside the outer casing. The plastic casing is often much larger than the busbar, occupying space for internal wiring or other device installation. This necessitates adding space for device installation within the plastic casing or the outer casing itself. Furthermore, the large size of the plastic casing makes fixing and installing the casing and other devices difficult, leading to complex assembly and higher costs for the power distribution equipment.

[0045] Embodiments of this application provide an installation assembly applied to power distribution equipment. The power distribution equipment includes a busbar and multiple functional modules electrically connected to the busbar. The installation assembly includes a housing, an inner housing, a first insulating post, and a second insulating post. The housing has an inner mounting wall. The inner housing is configured to accommodate the multiple functional modules and is disposed within the housing. One end of the first insulating post is fixed to the inner mounting wall, and the other end of the first insulating post is configured to be fixed to the busbar, with a first preset distance between the busbar and the inner mounting wall. The second insulating post is spaced apart from the first insulating post, with one end fixed to the inner mounting wall and the other end fixed to the inner housing, with a second preset distance between the inner housing and the inner mounting wall, the second preset distance being greater than the first preset distance.

[0046] By setting a first insulating post to support the busbar, a first preset distance is maintained between the busbar and the inner wall of the outer casing to meet the relevant standards for safe distances related to air insulation. A second insulating post supports the inner casing, creating a second preset distance between the inner casing and the inner wall of the outer casing. The inner casing can also maintain a second preset distance from the inner wall of the outer casing, ensuring that the functional module and the inner wall of the outer casing also meet the relevant standards for safe distances related to air insulation. Furthermore, the second preset distance is greater than the first preset distance, creating a staggered installation structure for the inner casing and busbar. Users can install the busbar and inner casing in layers according to their different heights, improving the problem of interference between the busbar and inner casing during assembly and facilitating user installation. The first and second insulating posts replace the plastic shells used in related technologies, allowing the busbar and inner casing to be fixed using the corresponding first and second insulating posts, eliminating the need for plastic shells. This reduces the steps of fixing the busbar and inner casing within the outer casing, simplifies the structure and assembly method of the power distribution equipment, improves the assembly efficiency of the power distribution equipment, and reduces the production cost of the power distribution equipment.

[0047] 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.

[0048] Please see Figure 1 and Figure 2 Embodiments of this application provide an installation component 100 and a power distribution device 200, wherein the installation component 100 is applied to the power distribution device 200. It is understood that the power distribution device 200 includes the installation component 100.

[0049] Distribution equipment 200 refers to the general term for various equipment and devices used in a power system to distribute electrical energy from the transmission network to the user end. It plays a role in voltage reduction, distribution, control, and protection within the power system and is an important component of power supply. Distribution equipment 200 includes modular distribution equipment, which refers to a form of distribution equipment where each functional unit in the distribution system is designed as an independent, interchangeable standard module, and then flexibly combined according to actual needs. This approach improves the flexibility, scalability, and ease of maintenance of the equipment.

[0050] Please see Figure 3 and Figure 4 In some embodiments, the power distribution equipment 200 includes a busbar 201 and a functional module 202, with the busbar 201 electrically connected to the functional module 202.

[0051] For example, multiple functional modules 202 are provided, and busbar 201 is electrically connected to multiple functional modules 202. Among them, multiple functional modules 202 include multiple branch modules, which are used for power distribution and protection circuits.

[0052] Please see Figure 2 In some embodiments, the power distribution equipment 200 further includes a main wiring module 203, which has an input bus and an output bus (not shown). The input bus of the main wiring module 203 is used to be electrically connected to the main power supply, and the output bus of the main wiring module 203 is electrically connected to the busbar 201. Since the busbar is also connected to multiple functional modules 202, the current of the main power supply is distributed to multiple branch modules through the busbar 201.

[0053] Among them, the main wiring module 203 is the core module of the power distribution equipment 200, which is responsible for power input, distribution and preliminary protection.

[0054] Please see Figure 2 and Figure 4 In some embodiments, the mounting assembly 100 includes a housing 10 and an inner housing 20, the housing 10 having an inner mounting wall 110; the inner housing 20 is configured to accommodate a plurality of functional modules 202, the inner housing 20 being disposed within the housing 10, and a busbar 201 being disposed within the housing 10 and located outside the inner housing 20.

[0055] The inner shell 20 is an insulating shell. By placing the functional module 202 in the inner shell 20, the functional module 202 is integrated to form a branch module. The busbar 201 is placed on the outside of the inner shell 20 to separate the busbar 201 of the functional module 202, thereby improving the problem of short circuit and damage caused by direct contact between the busbar 201 and the entire functional module 202.

[0056] Please see Figure 2 and Figure 4 In some embodiments, the mounting assembly 100 includes a first insulating post 30, one end of which is fixed to the mounting inner wall 110, and the other end of which is configured to be fixed to the busbar 201, and to provide a first preset distance between the busbar 201 and the mounting inner wall 110.

[0057] By setting the first insulating post 30 to support the busbar, a first preset distance is made between the busbar 201 and the mounting inner wall 110 of the housing 10 to meet the relevant standards for safe distances related to air insulation.

[0058] Please see Figure 2 In some embodiments, the outer casing 10 includes an outer casing body 11 and a casing cover 12. The outer casing body 11 has the aforementioned mounting inner wall 110; wherein, the mounting inner wall 110 includes a mounting side wall 111 and a mounting bottom wall 112, the mounting side wall 111 and the mounting bottom wall 112 are connected and arranged at an included angle; please refer to the following documents. Figure 5 and Figure 6For example, one end of the first insulating post 30 is connected to the mounting base wall 112, and the first insulating post 30 is spaced apart from the mounting side wall 111 so that the busbar 201 and the mounting side wall 111 have a first preset distance. The first insulating post 30 has a first preset distance from both the mounting side wall 111 and the mounting base wall 112 of the housing 10 to meet the relevant standards for safe distances related to air insulation, so that the insulation effect between the busbar 201 and the housing 10 is good.

[0059] Please see Figure 2 and Figure 4 In some embodiments, the mounting assembly 100 includes a second insulating post 40, which is spaced apart from the first insulating post 30. One end of the second insulating post 40 is fixed to the mounting inner wall 110, and the other end of the second insulating post 40 is fixed to the inner shell 20, so that the inner shell 20 and the mounting inner wall 110 have a second preset distance.

[0060] By setting the second insulating post 40, the inner shell 20 can have a second preset distance from the mounting inner wall 110 of the outer shell 10, so that the functional module 202 and the mounting inner wall 110 also meet the relevant standards for safe distances for air insulation.

[0061] Please see Figure 4 , Figure 5 and Figure 6 For example, one end of the second insulating post 40 is connected to the mounting bottom wall 112, and the second insulating post 40 is spaced apart from the mounting side wall 111 so that the inner shell 20 and the mounting side wall 111 have a second preset distance. The second insulating post 40 has a second preset distance from both the mounting side wall 111 and the mounting bottom wall 112 of the outer shell 10 to meet the relevant standards for safe distances related to air insulation, so that the insulation effect between the functional module 202 inside the inner shell 20 and the outer shell 10 is good.

[0062] The range of values ​​for the first and second preset distances can be determined based on the voltage range of different countries. For example, in the case of 120V voltage in the United States, both the first and second preset distances need to reach a range of 19.1mm or more to achieve air insulation.

[0063] In some embodiments, the second preset distance is greater than the first preset distance so that the inner shell 20 and the busbar 201 are arranged in a staggered installation structure. Users can install the busbar 201 and the inner shell 20 in layers according to their different heights, which improves the problem of mutual interference between the busbar 201 and the inner shell 20 during assembly and facilitates user installation.

[0064] The first insulating post 30 and the second insulating post 40 of this application replace the plastic shell in the related technology, so that the busbar 201 and the inner shell 20 can be fixed by the corresponding first insulating post 30 and the second insulating post 40 respectively, without the need to assemble the plastic shell. This reduces the steps of assembling the busbar 201 and the inner shell 20 into the outer shell 10, simplifies the structure and assembly method of the power distribution equipment 200, improves the assembly efficiency of the power distribution equipment 200, and reduces the production cost of the power distribution equipment 200.

[0065] In some embodiments, the first insulating post 30 includes a first support portion (not shown) and a first insulating portion (not shown), the first insulating portion wrapping around the first support portion to separate the busbar 201 and the housing 10, thereby achieving insulation between the busbar 201 and the housing 10.

[0066] In some embodiments, the first support is made of metal, thereby taking advantage of the good hardness, rigidity and corrosion resistance of metal to give the first support a good support strength, enabling it to bear heavy objects and achieve a good support effect.

[0067] In some embodiments, the second insulating post 40 includes a second support portion (not shown) and a second insulating portion (not shown), the second insulating portion wrapping around the second support portion, thereby separating the busbar 201 and the functional module 202 inside the inner shell 20 to achieve insulation between the functional module 202 inside the inner shell 20 and the outer shell 10.

[0068] In some embodiments, the second support is made of metal, thereby taking advantage of the good hardness, rigidity and corrosion resistance of metal to give the second support good support strength, enabling it to bear heavy objects and achieve a good support effect.

[0069] For example, the metal parts can be elemental metals or hard alloys; for example, copper and its alloys, iron and its alloys, etc., to achieve good support effect.

[0070] For example, the first insulating part and the second insulating part can be configured as one of rubber parts, silicone parts and plastic parts.

[0071] Please see Figure 4 , Figure 5 and Figure 6 In some embodiments, the height of the second insulating post 40 is greater than the height of the first insulating post 30, and the inner shell 20 is located above the busbar 201. The inner shell 20 is provided with an opening 25, which is located on the side of the inner shell 20 facing the busbar 201 and directly opposite the busbar 201. The opening 25 is configured to allow a portion of the functional module 202 to extend out and be electrically connected to the busbar 201.

[0072] Since the height of the second insulating post 40 is greater than the height of the first insulating post 30, the end of the second insulating post 40 away from the mounting bottom wall 112 protrudes from the first insulating post 30, so that the inner shell 20 and the busbar 201 are stacked, thereby making the structure of the inner shell 20 and the busbar 201 compact, and facilitating the connection of the functional module 202 and the busbar 201.

[0073] For example, please refer to Figure 4 The functional module 202 includes an input row 2020, a portion of which extends out of the outer side of the inner shell 20 through an opening 25. The busbar 201 is stacked and connected to the input row 2020 to make the structure between the busbar 201 and the input row 2020 compact and facilitate the connection between the busbar 201 and the input row 2020.

[0074] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the inner shell 20 is provided with a first clearance groove 21. The first clearance groove 21 has a first opening 210 and a first bottom wall 211. The first opening 210 is located on the side of the inner shell 20 away from the mounting inner wall 110. For example, the first opening 210 is located on the side of the inner shell 20 away from the mounting bottom wall 112. The first bottom wall 211 is located on the side of the inner shell 20 close to the mounting inner wall 110. The mounting assembly 100 includes an electrical connector 50. The electrical connector 50 enters the first clearance groove 21 through the first opening 210 and passes through the first bottom wall 211. A section of the electrical connector 50 extends out of the first bottom wall 211 and connects the busbar 201 and the functional module 202.

[0075] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the electrical connector 50 includes a bolt 51 and a nut 52. The bolt 51 passes through the input port 2020 and the busbar 201 of the functional module 202, with the bolt head abutting against the side of the input port 2020 away from the busbar 201. The nut 52 is fitted onto the bolt 51 and abuts against the side of the busbar 201 away from the input port 2020 to prevent the busbar 201 and the input port 2020 from separating. The bolt 51 and nut 52 enable a detachable connection between the busbar 201 and the input port 2020, facilitating the maintenance or replacement of the functional module 202 or the busbar 201.

[0076] By providing a first clearance groove 21 in the inner shell 20, with the first groove 210 located on the side of the inner shell 20 away from the mounting bottom wall 112, it is convenient for operators to assemble the electrical connector 50 from the side of the inner shell 20 away from the mounting bottom wall 112 (i.e., the outer side of the outer shell body 11). Furthermore, the first clearance groove 21 allows the electrical connector 50 to be properly positioned within it, ensuring that the electrical connector 50 will not protrude beyond the outer side of the inner shell 20 when other components need to be assembled there. This reduces interference between the electrical connector 50 and components on the outer side of the inner shell 20, and prevents scratching of components on the outer side of the inner shell 20.

[0077] For example, the inner shell 20 has a first shell wall 23 and a second shell wall 24, which are disposed opposite to each other. The first shell wall 23 is located on the side of the inner shell 20 facing the mounting bottom wall 112, and the second shell wall 24 is located on the side of the inner shell 20 away from the mounting bottom wall 112. The first opening 210 of the first relief groove 21 is disposed facing the second shell wall 24, and the bottom wall 211 of the first groove is the first shell wall 23. By completely placing the electrical connector 50 in the first relief groove 21, the problem of the electrical connector 50 protruding from the outer surface of the second shell wall 24 and easily scratching the components on the outside of the second shell wall 24 is improved.

[0078] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the first insulating post 30 includes a first rod portion 31 and a first fastening portion 32. One end of the first rod portion 31 is fixedly connected to the mounting inner wall 110, and the other end of the first rod portion 31 is used to abut against the busbar 201. The first fastening portion 32 passes through the busbar 201, and a section of the first fastening portion 32 extending out of the busbar 201 is fixed to the end of the first rod portion 31 away from the mounting inner wall 110. The end of the first fastening portion 32 away from the first rod portion 31 pushes against the busbar 201 in a direction closer to the mounting inner wall 110 to prevent the busbar 201 from detaching from the first rod portion 31. The first fastening portion 32 can pass through the busbar 201 and the first rod portion 31 from the end of the first rod portion 31 away from the mounting inner wall 110 to push against the busbar 201 and facilitates operation of the first fastening portion 32 from the outside of the housing by an operator.

[0079] For example, the first fastening part 32 may be one of bolts and screws to achieve a detachable connection between the first rod part 31 and the busbar 201, so as to facilitate the inspection or replacement of the busbar 201.

[0080] Understandably, the busbar 201 is installed inside the outer shell body 11 before the inner shell 20 is assembled, at which time the outer shell body 11 and the shell cover 12 are separated so that the operator can operate the first fastening part 32 from the outside of the outer shell body 11.

[0081] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the second insulating post 40 includes a second rod portion 41 and a second fastening portion 42. The second rod portion 41 is fixedly connected to the mounting inner wall 110 and passes through the inner shell 20, with one end of the second rod portion 41 away from the mounting inner wall 110 located inside the inner shell 20. The second fastening portion 42 passes through the inner shell 20 from the side away from the mounting inner wall 110 and is fixed to the end of the second rod portion 41 away from the mounting inner wall 110. The end of the second fastening portion 42 away from the second rod portion 41 pushes against the inner shell 20 in a direction close to the mounting inner wall 110 to prevent the inner shell 20 from detaching from the second rod portion 41. The second fastening portion 42 can be operated from the outside of the outer shell 10 to push against the inner shell 20, and it is convenient for the operator to operate the first fastening portion 32 from the outside of the outer shell.

[0082] For example, the second fastening part 42 may be one of bolts and screws to achieve a detachable connection between the second rod part 41 and the inner shell 20, so as to facilitate the inspection or replacement of the busbar 201 and the inner shell 20.

[0083] Understandably, the outer shell body 11 and the cover 12 are separate before the inner shell 20 is installed into the outer shell body 11 of the outer shell 10. The second fastening part 42 of this application passes through the inner shell 20 and the second rod part 41 from the side of the inner shell 20 away from the inner wall 110. That is, the second fastening part 42 can pass through the outer side of the outer shell body 11 into the inner shell 20 and the second rod part 41, so that the operator can install the inner shell 20 into the outer shell body 11.

[0084] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the inner shell 20 is provided with a second clearance groove 22. The second clearance groove 22 has a second opening 220 and a second bottom wall 221. The second opening 220 is located on the side of the inner shell 20 away from the second insulating post 40, and the second bottom wall 221 is located on the side of the second opening 220 close to the second insulating post 40. The second fastening part 42 enters the second clearance groove 22 through the second opening 220 and passes through the second bottom wall 221. A section of the second fastening part 42 that extends out of the second bottom wall 221 is fixedly connected to the second rod part 41.

[0085] By providing a second clearance groove 22, the second opening 220 of the second clearance groove 22 is located on the side of the inner shell 20 away from the second insulating post 40, so that the operator can operate the second fastening part 42 from the outside of the outer shell 10. In addition, the second clearance groove 22 can realize the clearance of the second fastening part 42, and the second fastening part 42 can be completely located in the second clearance groove 22, so that the second fastening part 42 will not protrude from the outer surface of the inner shell 20, thereby improving the problem of interference between the second fastening part 42 and the components on the outside of the inner shell 20, and the problem of easily scratching the components on the outside of the inner shell 20.

[0086] Understandably, the second slot 220 is provided on the second housing wall 24 to facilitate the operator to operate the second fastening part 42 from the outside of the housing body 11; and the second clearance slot 22 can allow the second fastening part 42 to be cleared, so that the second fastening part 42 can be completely located in the second clearance slot 22, so that the second fastening part 42 will not protrude from the second housing wall 24, thereby improving the problem of interference between the electrical connector 50 and the components on the second housing wall 24, and the problem of easily scratching the components on the second housing wall 24.

[0087] Please see Figure 5 and Figure 6 In some embodiments, multiple first insulating posts 30 and multiple second insulating posts 40 are provided. The multiple first insulating posts 30 and multiple second insulating posts 40 are divided into two support groups 310. Each support group 310 includes multiple first insulating posts 30 and multiple second insulating posts 40. The multiple first insulating posts 30 and multiple second insulating posts 40 of each support group 310 are distributed alternately along a first direction. The two support groups 310 are distributed at intervals along a second direction. The first direction is perpendicular to the second direction.

[0088] By setting multiple first insulating pillars 30 and multiple second insulating pillars 40, and dividing the multiple first insulating pillars 30 and multiple second insulating pillars 40 into two support groups 310, the multiple first insulating pillars 30 and multiple second insulating pillars 40 support the inner shell 20, and the multiple first insulating pillars 30 and multiple second insulating pillars 40 form a support surface, thereby improving the support strength and support stability of the first insulating pillars 30 and the second insulating pillars 40 for the busbar 201, the inner shell 20, and the functional module 202 located in the inner shell 20.

[0089] In some embodiments, the two sets of support groups 310 are respectively located on the edges of the inner shell 20 along its length direction, so as to improve the problem that the multiple first insulating pillars 30 and multiple second insulating pillars 40 of the two sets of support groups 310 occupy a lot of space in the inner shell 20, affect the installation of the functional module 202, and have a large overall volume of the inner shell 20, thereby improving the space utilization of the inner shell 20, reducing the volume of the inner shell 20, and thus reducing the volume of the outer shell 10.

[0090] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, multiple inner shells 20 are provided, each inner shell 20 being configured to accommodate a functional module 202, and at least one second insulating post 40 in each support group 310 is fixedly connected to an inner shell 20.

[0091] By setting up multiple inner shells 20, each of which houses a functional module 202, the modularity of a single functional module 202 is achieved. When a single functional module 202 is damaged, only the damaged functional module 202 can be repaired, which improves the problem that repairing a single functional module 202 may affect other functional modules 202. Furthermore, the multiple inner shells 20 and the multiple functional modules 202 form multiple branch modules, and the positions of the multiple branch modules can be arbitrarily changed, improving the flexibility of the power distribution equipment 200.

[0092] In some embodiments, each first insulating post 30 is detachably connected to the housing 10.

[0093] Please see Figure 3 and Figure 4 In some embodiments, the mounting assembly 100 includes a first fastener 60, and each first insulating post 30 is connected to the housing 10 via the first fastener 60.

[0094] For example, the first fastener 60 may be a screw or a bolt to enable the first insulating post 30 to be detachably connected to the housing 10; and, depending on the specific number of branch modules, a busbar 201 of appropriate length is selected, and a suitable number of first insulating posts 30 are provided in the housing 10 according to the length of the busbar 201, so as to further simplify the redundant structure in the housing 10.

[0095] In some embodiments, each second insulating post 40 is detachably connected to the housing 10.

[0096] Please see Figure 3 and Figure 4 In some embodiments, the mounting assembly 100 includes a second fastener 70, and each second insulating post 40 is connected to the housing 10 via the second fastener 70.

[0097] For example, the second fastener 70 may be a screw or a bolt to enable the second insulating post 40 to be detachably connected to the housing 10; and, depending on the specific number of branch modules, an appropriate number of second insulating posts 40 may be provided in the housing 10 to further simplify the redundant structure within the housing 10.

[0098] 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.
