Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0036] Furthermore, where the term "and / or" appears, it merely describes the relationship between related objects and indicates that three relationships can exist. For example, A and / or B can represent the relationship between A and B: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates an "or" relationship between the related objects before and after it. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature specified with "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, four, five, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0040] In addition to the problems described in the background art, in related technologies, the protection level of cable connections located outside the enclosure is low. Although the protection requirements can be met by using dedicated cable connectors, this method still has the problem of high cost.

[0041] Please see Figures 1 to 6 The electrical equipment in this application embodiment can be an energy storage converter, etc. For ease of explanation, this application embodiment uses an energy storage converter for description, and other types of electrical equipment are similar. An embodiment of this application provides an electrical equipment 100 including a housing 10 and an inlet / outlet wiring layout structure 20. The housing 10 has a first wiring port 11. The inlet / outlet wiring layout structure 20 is disposed inside the housing 10 and divides the space within the housing 10 into a first space 12 and a second space 13. The first wiring port 11 connects the external space of the housing 10 with the first space 12. The inlet / outlet wiring layout structure 20 has mounting holes that connect the first space 12 and the second space 13.

[0042] The mounting holes include terminal mounting holes, which connect the first space 12 and the second space 13. The electrical equipment 100 also includes wiring terminals 31, which are mounted in the terminal mounting holes. Understandably, the first wiring port 11 is used to route the external cable 210 of the electrical equipment 100 into the first space 12. One end of the wiring terminal 31 mounted in the terminal mounting hole is used to connect to the external cable 210 located in the first space 12, and the other end is used to connect to the internal cable 210 located in the second space 13. Specifically, it includes AC side wiring terminals and DC side wiring terminals.

[0043] In addition to terminal mounting holes, mounting holes may also include other types of mounting holes for mounting other devices, such as signal terminals 33, exhaust valves 35, etc. The first space 12 may also be used to mount other devices, without specific limitations here.

[0044] The aforementioned electrical equipment 100 has an inlet / outlet wiring layout structure 20 inside its enclosure 10. The internal space of the enclosure 10 is divided into a first space 12 and a second space 13 by the wiring layout structure. The inlet / outlet wiring layout structure 20 has terminal mounting holes, through which wiring terminals 31 can be installed on the inlet / outlet wiring layout structure 20. External cables 210 enter the first space 12 from the first wiring port 11 and connect to the wiring terminals 31, while internal cables 210 connect to the wiring terminals 31 in the second space 13.

[0045] Thus, the incoming and outgoing wiring layout structure 20 can transfer the wiring position from the surface of the enclosure 10 of the electrical equipment 100 to the first space 12 inside the enclosure 10. The wiring has less external occupation and impact, which helps to reduce the space occupied by the electrical equipment 100 and facilitates the integration of multiple electrical equipment 100 into the energy storage unit. In addition, since the incoming and outgoing wiring layout structure 20 divides the enclosure 10 to form the first space 12, the connection position of the cable 210 in the first space 12 is protected by the enclosure 10. Even without the use of dedicated cable connectors, the protection level can be significantly improved, meeting the high protection requirements.

[0046] In some embodiments, the inlet / outlet cable layout structure 20 is located at the bottom corner of the housing 10, and the first cable routing port 11 is located on the bottom surface of the housing 10.

[0047] Understandably, the cable entry / exit layout structure 20 is installed inside the housing 10 and located above the first cable routing port 11, so that the first space 12 formed by its separation is located above the first cable routing port 11.

[0048] Specifically, the enclosure 10 can be, but is not limited to, a cuboid shape, and is relatively flat overall, with a small facet on its periphery serving as the front. The cable entry / exit layout structure 20 is located inside the enclosure 10, between two large faces on the periphery of the enclosure 10, and together with the bottom surface, front surface, and at least one large facet of the enclosure 10, defines a first space 12. The first cable routing opening 11 is located in the bottom surface of the enclosure 10 to define the portion forming the first space 12.

[0049] Thus, the inlet and outlet line layout structure 20 is located at the corner of the box 10, which has little impact on the internal space of the box 10 and facilitates installation and arrangement.

[0050] In some embodiments, the housing 10 includes a main body 15 and a cover plate 16. The main body 15 has an opening on one side, and the cover plate 16 is detachably installed at the opening of the main body 15. The inlet / outlet wiring layout structure 20 is connected to the main body 15 and together with the main body 15 defines a first space 12, which is separated from the second space 13.

[0051] In this way, users can remove the cover plate 16 to inspect the interior of the electrical equipment 100. The first space 12 is defined by the incoming and outgoing line layout structure 20 and the main body 15. Even if the user removes the cover plate 16, it will not affect the independence of the first space 12, and dust will not enter the second space 13 through the first space 12.

[0052] Specifically, the main body 15 can be roughly rectangular, with one large horizontal surface being an opening. An opening is provided on the opening surface, and a cover plate 16 is placed on the opening surface to cover the opening.

[0053] The cable entry / exit layout structure 20 includes a main board body 21 and a side plate body 23, both of which can be sheet metal parts. One side of the main board body 21 is connected to the large surface of the main body 15 opposite to the opening surface. The two ends of the main board body 21 are respectively connected to the bottom and front surfaces forming the bottom corners of the main body 15, and the main board body 21 is located above the first cable routing port 11. The side plate body 23 is connected to the side of the main board body 21 near the cover plate 16, so that together with the main board body 21, the large surface, bottom surface, and front surface of the main body 15, it forms a first space 12 connecting to the first cable routing port 11. Even if the cover plate 16 is removed, the side plate body 23 can still cover the first space 12, achieving the effect of separating the first space 12 and the second space 13 formed by the cable entry / exit layout structure 20.

[0054] Please refer to the following: Figures 7 to 8 In some embodiments, the electrical equipment 100 further includes a first seal 40, which is disposed in the housing 10 and located at the first wiring port 11, and has a second wiring port 41 communicating with the first space 12.

[0055] Understandably, the mounting base 220 for installing the electrical equipment 100 is provided with a third wiring port 221. The first wiring port 11 may be slightly larger than the third wiring port 221, and the second wiring port 41 may be slightly smaller than the third wiring port 221. Specifically, the first sealing member 40 seals the connection between the housing 10 and the first wiring port 11. When installing the electrical equipment 100, the first wiring port 11 and the third wiring port 221 are aligned and fitted together, and the third wiring port 221 connects to the first space 12 through the second wiring port 41 provided by the first sealing member 40. The mounting base 220 may be the frame of the integrated energy storage unit.

[0056] Thus, when the electrical equipment 100 with the incoming and outgoing wiring layout structure 20 is integrated into the frame of the energy storage unit, the first wiring port 11 is roughly aligned with the third wiring port 221 of the frame, and the two are sealed by the first sealing member 40. The cable 210 can pass through the second wiring port 41 of the first sealing member 40 from the third wiring port 221 of the frame to enter the first space 12 and connect to the terminal 31. The first sealing member 40 can reduce the assembly precision requirements of the first wiring port 11 and the third wiring port 221, so that the joint between the two has high protection.

[0057] Specifically, the first seal 40 may have at least a partially sealed area, which is made of an elastic material and is elastic. One end of the first seal 40 is used to connect to the housing 10, and the other end is used to connect to the mounting base 220, with the sealed area located at least between the two ends. Specifically, the first seal 40 may be, but is not limited to, a silicone cover plate 16.

[0058] Furthermore, the inlet / outlet wiring layout structure 20 also includes a fitting 50 and a pressure plate 60. The first seal 40 is connected to the housing 10 via the fitting 50 around the first wiring port 11. The pressure plate 60 is located on the side of the first seal 40 facing away from the mounting base 220 where the electrical equipment 100 is installed and is arranged around the second wiring port 41, and is used to press the first seal 40 against the mounting base 220.

[0059] Specifically, the fitting 50 and the pressure plate 60 can be sheet metal parts that conform to the shapes of the first wiring port 11 and the third wiring port 221, respectively. The fitting 50 can exert a clamping force on the first seal 40 towards the housing 10, so that it fits tightly against the housing 10. The pressure plate 60 can exert a clamping force on the first seal 40 towards the mounting base 220, so that it fits tightly against the mounting base 220. The pressure plate 60 also surrounds the periphery of the third wiring port 221. In other words, the fitting 50 can clamp the outer edge of the first seal 40 together with the edge of the first wiring port 11, and the pressure plate 60 can clamp the inner edge of the first seal 40 together with the edge of the third wiring port 221.

[0060] In one embodiment, the assembly 50 is located within the first space 12, and the outer edge of the first seal 40 is sandwiched between the assembly 50 and the edge of the housing 10 at the first wiring port 11, with the assembly 50 pressing against the edge of the housing 10. In another embodiment, the assembly 50 may also be located outside the first space 12, with the outer edge of the first seal 40 sandwiched between the assembly 50 and the edge of the housing 10 at the first wiring port 11, with the assembly 50 pressing against the edge of the housing 10. Furthermore, the assembly 50 may also connect the first seal 40 to the housing 10 around the first wiring port 11 in other ways, without specific limitations.

[0061] The assembly 50 and the pressure plate 60 are provided with multiple screw holes so that the housing 10 and the mounting base 220 can be connected by screws, and the first seal 40 can be pressed by tightening the screws.

[0062] In this way, by connecting and fixing the first sealing element 40 with the mounting part 50 and the pressure plate 60, the enclosure 10 and the frame of the electrical equipment 100 are tightly fitted at the first wiring port 11 and the third wiring port 221.

[0063] In some other embodiments, the assembly 50 and the housing 10 can also be connected by welding. The clamping force generated by the assembly 50 and the pressure plate 60 on the first seal 40 can be generated by magnetic attraction, riveting, welding, locking, etc., which are not specifically limited here.

[0064] Furthermore, the first seal 40 has a deformable rib 43 surrounding the second wiring port 41, the fitting 50 is located in the area of ​​the first seal 40 outside the deformable rib 43, and the pressure plate 60 is located in the area of ​​the first seal 40 inside the deformable rib 43.

[0065] Understandably, the deformable rib 43 can undergo elastic deformation, and the areas inside and outside of it can undergo relative displacement through its deformation. Both the assembly 50 and the pressure plate 60 can be sheet metal parts.

[0066] Thus, when the assembly 50 connects the first seal 40 to the first wiring port 11 of the housing 10 through its outer area, the pressure plate 60 can press the inner area of ​​the first seal 40 against the edge of the third wiring port 221 of the mounting base 220 through the deformation adaptation of the deformable rib 43, so that the third wiring port 221 is sealed and connected to the first space 12 through the first seal 40.

[0067] In some embodiments, the housing 10 further has an operation port 14, which is located on the peripheral side where the housing 10 intersects with the bottom surface, and the operation port 14 is connected to the first space 12.

[0068] Understandably, for ease of operation, the operating port 14 may be located on the front of the electrical equipment 100, so that the user can operate the device located in the first space 12 through the operating port 14. Specifically, the opening of the operating port 14 may be horizontal, and the mating port may be formed on the front of the electrical equipment 100.

[0069] In this way, while the entry and exit points are located at the bottom of the electrical equipment 100 to facilitate wiring, users can perform wiring and maintenance through the operation port 14 on the front, making the wiring of the electrical equipment 100 easier and subsequent maintenance more convenient.

[0070] In some embodiments, the inlet / outlet cable layout structure 20 further includes a cover 70, which is detachably disposed over the operating port 14. Further, the inlet / outlet cable layout structure 20 also includes a second seal 80, which is sealingly connected between the housing 10 and the cover 70.

[0071] The second sealing element 80 can be a waterproof strip, which can prevent water from entering the first space 12 from between the cover 70 and the box 10. Specifically, the cover 70 can be a sheet metal part.

[0072] Thus, when wiring or maintenance operations are required, the user can remove the cover 70 to expose the operating port 14. After the wiring or maintenance operations are completed, the user can put the cover 70 back on to cover the operating port 14 and seal it with the second seal 80 to improve the sealing of the connection between the two, thereby improving the protection of the wiring location.

[0073] In some embodiments, the incoming / outgoing line layout structure 20 includes at least two wiring structure surfaces 211, each of which is provided with a terminal mounting hole. In the vertical direction (e.g.) Figure 6 In the X direction (as shown), at least a portion of each wiring structure surface 211 is at a different height. In the horizontal direction (e.g., Figure 6 On the Y direction shown, each wiring structure surface 211 is spaced apart.

[0074] Specifically, one side of the wiring structure surface 211 faces the operating port 14, and each wiring structure surface 211 is arranged sequentially along the opening direction of the operating port 14. The wiring structure surface 211 that is closer to the operating port 14 is higher, and at least a portion of the area of ​​each wiring structure surface 211 is at a different height.

[0075] Understandably, the various wiring structure surfaces 211 are staggered in both the horizontal and vertical directions, and the terminals 31 on different wiring structure surfaces 211 are used to connect different cables 210. Specifically, the terminal mounting holes on one wiring structure surface 211 are used to install DC side terminals, and the terminal mounting holes on another wiring structure surface 211 are used to install AC side terminals. In addition, each wiring structure surface 211 may have at least one mounting hole, and the operating port 14 may face each wiring structure surface 211.

[0076] In this way, different cables 210 can be routed vertically into the first space 12, and when connected to their respective corresponding terminals 31, they are staggered in the vertical and horizontal directions, which facilitates the user to connect the cables in sequence and perform subsequent maintenance.

[0077] Furthermore, the incoming and outgoing line layout structure 20 includes a main board body 21, which is stepped, and at least part of the structural surface of the main board body 21 intersecting with the horizontal direction forms a wiring structure surface 211.

[0078] Understandably, the stepped structure is formed by alternating and sequentially connecting at least two horizontal planes and at least one vertical plane, wherein the horizontal plane is equivalent to the tread of the step, the vertical plane is equivalent to the riser of the step, and at least part of the riser serves as the connection structure plane 211. The vertical planes of different steps are at different heights and are spaced apart from each other in the horizontal direction.

[0079] Thus, the motherboard body 21 has a stable structure and can be formed by folding sheet metal parts, making the manufacturing process simple. In addition, a stepped first space 12 can be formed below the motherboard body 21, with different height spaces within the first space 12, which can be used to place different components respectively.

[0080] The aforementioned electrical equipment 100 includes a housing 10, an inlet / outlet wiring layout structure 20, a first sealing element 40, an assembly 50, a pressure plate 60, a cover 70, and a second sealing element 80. The inlet / outlet wiring layout structure 20 is located inside the housing 10. The internal space of the housing 10 is divided into a first space 12 and a second space 13 by the wiring layout structure, and the first space 12 and the second space 13 are separated from each other. The first space 12 is located inside the housing 10 and has a high level of protection due to the protection of the housing 10. Therefore, ordinary wiring terminals 31 can be used for inlet and outlet wiring. Specifically, the main body 21 of the inlet / outlet wiring layout structure 20 is folded into a stepped shape, and the wiring structure surface 211 is staggered front to back and top to bottom, so that AC and DC wiring terminals 31 and other devices are on different planes, increasing the space for wiring and assembly, and reducing the space occupied between devices. The electrical devices that can be installed in the mounting holes and the first space 12 include AC side wiring terminals, DC side wiring terminals, signal terminals 33, exhaust valves 35, etc. Furthermore, when electrical equipment 100 is integrated into the energy storage unit, it can be placed very compactly. The first space 12 already has reserved space for wiring and connections, effectively reducing space waste in the integrated product. Users can easily perform wiring or maintenance work from the front after removing the cover 70, improving the maintenance convenience of the integrated product.

[0081] The first space 12 is an independent cavity, and a first sealing element 40 is provided at the first wiring port 11 connected to it. When the electrical equipment 100 is integrated, the third wiring port 221 on the mounting base 220 connects to the first space 12 through the second wiring port 41 left in the first sealing element 40, so that the two have high protection when they are connected, which can effectively protect the internal components of the structure. Specifically, when the electrical equipment 100 is integrated into the frame of the energy storage unit, its bottom cooperates with the frame, which serves as the mounting base 220. The user uses screws or other methods to fix it, and uses the pressure plate 60 to press the first sealing element 40 tightly. The first sealing element 40 is made of silicone and has elasticity, which can effectively reduce the protection risk caused by the deviation of the frame opening size and achieve high protection.

[0082] Thus, the incoming / outgoing cable layout structure 20 provides high protection, achieving an IP54 or higher protection level even when using ordinary terminal blocks 31 for wiring, which helps reduce costs. The electrical equipment 100 can concentrate the incoming and outgoing cable positions within the internal cavity through the incoming / outgoing cable layout structure 20, resulting in a smaller space footprint after wiring. The wiring structure surfaces 211 of the incoming / outgoing cable layout structure 20 are staggered front and rear, reducing wasted space within the system and minimizing product size. Furthermore, the electrical equipment 100 has an operation port 14 for easy wiring, maintenance, and other operations. The bottom of the electrical equipment 100 has a first sealing element 40, which reduces the precision requirements for the fit between the first wiring port 11 and the third wiring port 221, allowing for a certain dimensional deviation between them.

[0083] This application also provides an integrated energy storage unit, including the aforementioned electrical equipment 100. Specifically, the integrated energy storage unit includes a frame, and the electrical equipment 100 is installed within the frame; in other words, the frame serves as the mounting base 220 for the electrical equipment 100. A third cable routing port 221 for cables 210 to pass through is provided on the frame. The third cable routing port 221 aligns with the first cable routing port 11 and is sealed and connected to the first space 12 via a first sealing member 40. Furthermore, screw holes for connecting a pressure plate 60 are provided around the third cable routing port 221 on the frame.
