Description

31 Junction box for electrical cabling, and how the box works. Field of invention

[001] The present innovation belongs to the field of Engineering, in its technological aspect of modular infrastructure, more specifically, in a junction box developed for the interconnection of electrical cabling between the modules that make up each room of the modular data center system, such as electrical rooms, data rooms, redundant electrical rooms, cooling rooms and telecommunications rooms, but not limiting the invention to this single field, since the product can be applied in the most diverse technological areas of Engineering. Background of the invention

[002] The demand for data center facilities has been steadily increasing with the rise in global connectivity. This growth directly impacts the capacity for data storage, processing, and control, which can be used in a wide variety of industries, businesses, offices, shopping malls, shops, and even leisure environments. All the technology applied in the most diverse solutions has a data center behind its operation.

[003] The demand for data centers available for the completion of construction projects in periods of less than one year is a need that has not yet been met in the state of the art, with traditional masonry constructions, which typically take about three years, depending on the capacity of the data center. Petition 870250006114, dated 01 / 25 / 2025, page 8 / 89 / 31 However, the urgency for data centers to become operational requires that this development and installation time for the data center be reduced, potentially reaching a timeframe of less than 6 (six) months, starting with the contracting process, going through project development, manufacturing, transportation, installation, testing, and activation.

[004] The solution of a modular data center system allows meeting the requirement for rapid availability of ready-to-use equipment. Therefore, solutions are needed that expedite the assembly of such solutions in the installation area of ​​the modular data center system. One difficulty of the prior art is the electrical integration between the modules that make up each room of the modular data center system.

[005] Furthermore, considering that the modular data center system has the flexibility to be expanded or reduced after it is already installed and in use, for this condition of expansion or reduction of the processing or storage capacity of the data center, having a solution that allows the electrical cabling of each module in the room to be connected and disconnected quickly and easily greatly facilitates and speeds up this process of expanding or reducing the operational capacity of the modular data center system.

[006] In addition to the ease and speed of electrical connection, it is also necessary to ensure the safety of the data center; that is, the developed junction box needs to be secure enough to prevent any risk of disconnection of the electrical cables during the room's operation. It is also necessary Petition 870250006114, dated 01 / 25 / 2025, page 9 / 89 / 31, that such a solution be a safe protection for people accessing the room for maintenance or eventual interventions.

[007] In order to obtain a solution that resolves all the technical problems listed above, with all their adversities, this document describes the electrical cabling junction box, used in the rooms of the modular data center system, capable of meeting all the requirements listed above.

[008] Several solutions have been developed seeking optimization and improvements for data centers, more specifically in solutions for electrical cabling, given the need for and care required by these components.

[009] In 2018, patent US20210143595, whose family includes patent application BR 11 2019 018693-, entitled “QUICK CONNECTION DEVICE FOR EMBEDDED ELECTRICAL INSTALLATIONS”, described as a solution the use of a quick connection for embedded electrical installations; this solution is basically a combination of an electrical plug and socket for recessed lighting. The solution developed in patent US20210143595 aims to facilitate the installation of electrical equipment such as fans or light fixtures, in order to facilitate recessed installation.Although the purpose of this patent is to facilitate electrical installation, as with the developed solution, the specification requirements of the present solution are much more complex, since it demands the electrical installation of rooms used in a modular data center system, which are environments with very high energy consumption, and therefore require robust solutions, in addition to the safety risks and guarantee of the electrical installation's operation. Thus, it was necessary to develop a whole new system. Petition 870250006114, dated 01 / 25 / 2025, page 10 / 89 / 31 structure that meets these requirements, which is quite different from the plug and socket developed in patent US20210143595.

[0010] In 2017, patent application BR 10 2017 013843-7 described a means of connecting conduits to a junction box. Although it has the same scope as the solution described in this document, which is to provide a solution that facilitates connection in order to make it faster and more efficient, the solution proposed in patent application BR 10 2017 013843-7 differs completely from the solution described in this document, since the solution proposed in patent application BR 10 2017 013843-7 is a small metal box, commonly used in residential socket installations, also known as a junction box, which was coupled to a conduit-type pipe through the use of a bushing and a sleeve. Meanwhile, the solution developed in this document is much more complex, since it involves powering the entire modular data center system, with power loads that can exceed 36 Megawatts.

[0011] In 2002, US patent 20020197910, whose family includes patent application PI 0205664-0, entitled “QUICK CONNECTION ASSEMBLY FOR ASSEMBLING ELECTRICAL INSTALLATIONS,” proposed a socket and receptacle mounted in a bell-shaped housing. The field of invention of patent application PI 0205664-0 considers suspended electrical installations, involving the assembly of the electrical installation. Although sharing the same field of invention, the solution developed in this document is a much more robust solution, since it aims to serve the entire installation. Petition 870250006114, dated 01 / 25 / 2025, page 11 / 89 / 31 regarding the energy capacity demanded by each room in a modular data center system.

[0012] In short, none of the documents available in the state of the art proposed the development of a junction box for electrical cabling in a modular data center system, sized to ensure safe coupling between the electrical cabling of each module that makes up a room. This solution is one of the technologies used to enable the operation of a modular data center system in a period of less than six months, while still guaranteeing all safety requirements and protection against electrical accidents, through a robust coupling system meticulously developed to ensure all these requirements.Another striking feature is its versatility in installation, as it can be quickly transported from different locations where it was initially installed, thanks to the decoupling solutions integrated into the junction box for electrical cabling, from the rooms used in the assembly of the modular data center system. Objectives of the Invention

[0013] The present innovation aims to develop a junction box for electrical cabling, used in the room modules of the modular data center system, capable of allowing easy and quick coupling between the modules.

[0014] Furthermore, the innovation developed also aims to provide robust insulation and electrical protection in the connection between the Petition 870250006114, dated 01 / 25 / 2025, page 12 / 89 / 31 cabling of each module that are joined to compose one of the rooms, of the modular data center system.

[0015] It is also the objective of the pass-through box to guarantee full availability for operation throughout 365 days a year, without any interruption of data storage or processing operations or other operations performed by the rooms, of the modular data center system.

[0016] The objective of this solution is to resolve the difficulty between the operations of removing the electrical cabling from each module and re-routing the electrical cabling during the reassembly of the modules.

[0017] And, still with regard to the operation of the junction box, the objective of this solution is to develop a method that describes the operation of the junction box for the electrical cabling of the rooms, of the modular data center system. Brief description of the figures

[0072] Figure 54 illustrates the right side view, enlarged by detail H, of the redundant electrical room junction box of the modular data center system. Detail H was identified in Figure 53. Description of the invention

[0073] Because the modular data center system has the versatility of being fully manufactured in one factory and transported in modules only for assembly in the final area of ​​use, as well as the flexibility to be transferred from one area to another, all this movement of modules brings extreme difficulty to removing all the cabling from a module so that each module can be transported individually. Furthermore, it is necessary to reroute all the electrical cabling when reassembling the modules. This difficulty in collecting dozens of meters of electrical cabling, transporting the modules, and rerouting all the cabling motivated the development of the innovation described in this document.

[0074] The electrical cable junction box is an element developed to organize and protect cable connections where the sectioning of feeder interconnections is required, in order to have a safe and orderly distribution in the module sections. The solution was designed to meet all needs and configurations, through a quick and secure connection, facilitating installations that, without the junction box, would require extensive work to remove the entire installation. Petition 870250006114, dated 01 / 25 / 2025, page 20 / 89 / 31 of the electrical cables and the subsequent passage of all the electrical cable installation between the modules. The developed box ensures safety and functionality, as it keeps the cable connections accommodated and accessible, preventing overloads and problems in the electrical system, thus ensuring total operational safety.

[0075] Guarantee the connection of cables at critical points in the connections between feeders installed in the electrical room, or in the redundant electrical room, or in the other rooms of the modular data center system, which require derivations to allow the separation of modules for their respective individual transport and facilitate a quick and safe connection at the time of coupling the modules, avoiding the installation difficulties and possible connection failures, already mentioned above.

[0076] In order to show how the solution is used in the structure of a modular data center system, Figure 1 presents a front perspective view of the modular data center system. In this view, it is possible to visualize the data room, the cooling room, the electrical room, and the redundant electrical rooms. Figure 1 also indicates the orthogonal axes X, Y, and Z. The X-axis indicates the longitudinal direction of the structures, a dimension also known as the length of the structures; the Z-axis indicates the transverse direction of the structures, a dimension also known as the width of the structures; and finally, the Y-axis indicates the direction parallel to the height of the structures.

[0077] The previous perspective view, illustrated in figure 2, shows another configuration for a modular data center system, which consists of two data rooms, two cooling rooms, one room Petition 870250006114, dated 01 / 25 / 2025, page 21 / 89 / 31 electrical and two redundant electrical rooms and a telecommunications room, which is not visible in this figure. Other alternative configurations can be used, since 1 electrical room and 2 redundant electrical rooms are capable of serving different numbers of data rooms, potentially up to 12 data rooms, depending on the total capacity demanded by the modular data center system.

[0078] In order to show various applications for the developed solution, Figure 3 is presented, which is a front perspective view of the electrical room used in a modular data center system. This figure allows visualization of the external geometry of the room structure, in which the junction box is mounted in the internal area of ​​the room, of the modular data center system.
