Description

Technical Field

[0001] This invention relates to the field of data center technology, and in particular to a data center busbar connector structure. Background Technology

[0002] In large-scale power consumption scenarios such as data centers and industrial plants, busbar systems are critical infrastructure for power distribution. This system typically includes busbars and junction boxes for drawing power. During installation, the pins in the junction boxes need to be connected to the conductive bars in the busbar trunking.

[0003] However, in existing technologies, some busbar trunking systems are designed with a symmetrical structure for ease of construction and manufacturing. This symmetrical design presents a serious safety hazard: if the plug-in box is installed in a 180-degree reverse orientation when connecting to the busbar trunking, it will cause phase sequence disorder, such as phase A being mistakenly connected as phase C, which can lead to a serious short circuit, potentially damaging equipment or even endangering personal safety.

[0004] Therefore, how to fundamentally eliminate phase misalignment problems during installation in a simple, reliable, and low-cost manner is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a data center busbar connector box structure to solve the technical problem in the prior art where phase sequence disorder easily occurs when the connector box is connected to the busbar trunking, leading to serious short circuit accidents. The various technical effects of the preferred technical solutions provided by this invention are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The data center busbar connector box structure provided by this invention includes a connector box, a busbar, connectors, and an interlocking plate, characterized in that: The interlocking plate is fixedly installed on the plug-in box.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0022] This invention provides a data center busbar plug-in box structure that, through mechanical structure, fundamentally eliminates the risk of electrical phase reversal caused by reverse installation of the busbar and the plug-in box.

[0023] The following is combined with Figures 1-5 The technical solution provided by this invention will be described in more detail below.

[0024] See Figures 1-5 As shown, the data center busbar plug-in box structure provided by the present invention includes a plug-in box 1, a busbar 4, a plug 2, and an interlocking plate 3. The interlocking plate 3 is fixedly installed on the plug-in box 1. The interlocking plate 3 is provided with a first guide structure and a second guide structure. The first guide structure and the second guide structure have different mechanical features. The busbar 4 is provided with a first guided structure that cooperates with the first guide structure and a second guided structure that cooperates with the second guide structure, so that the busbar 4 can only be installed with the interlocking plate 3 in a single direction. A positioning mechanism is provided between the plug 2 and the plug-in box 1. The positioning mechanism is used to limit the installation direction of the plug 2. The plug 2 is provided with an electrical connection terminal, which is electrically connected to the conductor inside the busbar 4.

[0025] The plug box 1 is used to draw power from the busbar 4 to supply downstream equipment. In this embodiment, the interlocking plate 3 cooperates with the plug 2 to ensure that the busbar 4 and the plug box 1 can only be mechanically and electrically connected in a unique and correct direction.

[0026] See Figure 1 , Figure 2 and Figure 5As shown, the interlocking plate 3 can be made of metal materials (such as steel plates, aluminum alloys, etc.) through processes such as stamping, bending, and machining, or it can be made of engineering plastics (such as polycarbonate, reinforced nylon, etc.) with sufficient mechanical strength and heat resistance through injection molding, thus balancing strength and manufacturing cost. The interlocking plate 3 is provided with a base plate. This base plate, as the main part of the interlocking plate 3, is used to install on the top surface of the plug-in box. The installation method can be screws, rivets, or clips, etc., to ensure a stable connection between the interlocking plate 3 and the plug-in box 1.

[0027] See Figure 1 , Figure 2 and Figure 5 As shown, to guide and limit the busbar 4, the bottom plate of the interlocking plate 3 extends upward on both sides, forming two key guiding structures integrally or subsequently connected. In this embodiment, these two guiding structures are designed as slots with different mechanical features. One side forms the first guiding structure, namely the busbar wide bottom edge slot 31; the other side forms the second guiding structure, namely the busbar narrow bottom edge slot 32. The busbar wide bottom edge slot 31 and the busbar narrow bottom edge slot 32 extend along the installation direction (i.e., the sliding direction) of the busbar 4.

[0028] The core difference between the wide bottom edge slot 31 and the narrow bottom edge slot 32 of the busbar lies in their internal width: the width of the wide bottom edge slot 31 is significantly greater than the width of the narrow bottom edge slot 32. This asymmetry in width provides a guarantee for achieving physical error prevention.

[0029] See Figure 1 , Figure 2 and Figure 3 As shown, busbar 4 is a long strip-shaped shell with a cavity 43, and the conductor inside is a copper busbar 46.

[0030] The bottom of the busbar 4 housing has two bottom edges, either bent inwards or integrally formed. One side is the first guided structure, i.e., the first bottom edge 41, whose width matches the width of the wide bottom edge slot 31 of the busbar on the interlocking plate 3, allowing it to slide in smoothly. The other side is the second guided structure, i.e., the second bottom edge 42, whose width matches the width of the narrow bottom edge slot 32 of the busbar on the interlocking plate 3. Because the width of the first bottom edge 41 is greater than the width of the narrow bottom edge slot 32 of the busbar, if an attempt is made to rotate the busbar 4 180 degrees for reverse installation, its first bottom edge 41 will not be able to enter the narrow bottom edge slot 32 of the busbar, and the installation process will be physically prevented. Similarly, the narrow bottom edge cannot obtain stable support in the wide bottom edge slot 31 of the busbar. Thus, through this simple and clear mechanical difference in width, the only installation direction of the busbar 4 relative to the interlocking plate 3 (and its fixed plug-in box 1) is forcibly defined.

[0031] To fix the installation direction of pin 2, a positioning mechanism is set between pin 2 and the connector box 1, see [link / reference]. Figure 4 As shown, the positioning mechanism includes a positioning protrusion 21 and a positioning hole 11, wherein: the positioning protrusion 21 is fixed to the bottom of the pin 2, and the positioning hole 11 is provided on the plug box 1, or the positioning protrusion 21 is fixed to the plug box 1, and the positioning hole 11 is provided on the bottom of the pin 2; the positioning hole 11 and the positioning protrusion 21 are engaged and plugged in.

[0032] Accordingly, on the top surface of the connector box 1, there is a mounting positioning hole 11 for the pin 2 that perfectly matches the shape, size, and position of the positioning protrusion 21. When installing the pin 2, the positioning protrusion 21 at its bottom must be aligned with and inserted into the mounting positioning hole 11 of the pin 2 in the connector box 1 to securely install the pin 2 in place. This matching relationship between the protrusion and the recess ensures that the pin 2 can only be installed at a fixed rotation angle relative to the connector box 1.

[0033] As an optional implementation, the busbar 4 further includes a housing 44 and an insulating kit 45, wherein the conductor is fixed to the inner wall of the housing 44, and the insulating kit 45 is located between the conductor and the housing 44. The top of the busbar 4 is provided with a grounding port 47, and the busbar 4 is provided with a receiving cavity 43 for insertion.

[0034] See Figure 4 As shown, the electrical connection terminals include side resilient plug terminals 22 and top resilient plug terminals 23, wherein: the side resilient plug terminals 22 are disposed on the side of the plug pin 2, and the top resilient plug terminals 23 are disposed on the top of the plug pin 2; the side resilient plug terminals 22 are used for electrical connection with the copper busbar 46, and the top resilient plug terminals 23 are used for electrical connection with the grounding port 47 to ensure safe grounding of the equipment. The side resilient plug terminals 22 are located on opposite sides of the plug pin 2, and on one side of the plug pin 2, the number of side resilient plug terminals 22 is one or more.

[0035] As an optional implementation, see Figure 5 As shown, the interlocking plate 3 is provided with an installation port 33 for the pin 2 to pass through, so that the bottom of the pin 2 can pass through the installation buckle and be fixed to the plug box 1.

[0036] The size and position of the mounting buckle match the bottom of the pin 2. During assembly, the bottom of the pin 2 first passes through the mounting opening 33 of the interlocking plate 3, and its bottom positioning protrusion 21 then engages with the positioning hole 11 on the connector box 1 for fixation. The pin 2 can pass through the mounting hole of the connector box 1 through the connecting bolt (not shown in the figure) provided at its bottom, and be tightened with a nut from inside the connector box 1, thereby firmly fixing the pin 2 and the interlocking plate 3 to the connector box 1 together.

[0037] The following is combined with Figures 1-5The installation process and error-proofing principle of the entire electrical connection assembly are explained in detail. First, fix pin 2 and interlocking plate 3 to the connector box 1. The installer places interlocking plate 3 on top of connector box 1, aligning the mounting opening 33 with the area on connector box 1 for mounting pin 2. Then, insert pin 2 through mounting opening 33 from above interlocking plate 3, carefully aligning the positioning protrusion 21 at the bottom of pin 2 with the pin 2 mounting positioning hole 11 at the top of connector box 1, ensuring they are properly inserted. Finally, secure pin 2 and interlocking plate 3 together to connector box 1 using bolts or other fasteners.

[0038] Next, the busbar 4 and the interlocking plate 3 guide structure are aligned. The installer must align the first bottom edge 41 of the busbar 4 with the wide bottom edge slot 31 of the busbar on the interlocking plate 3, and simultaneously align the second bottom edge 42 with the narrow bottom edge slot 32 of the busbar. Due to the significant difference in width, the correct alignment can be quickly found through simple trial and error, even in low-light conditions. Any incorrect alignment, such as attempting to align the first bottom edge 41 with the narrow bottom edge slot 32 of the busbar, will immediately cause mechanical interference, making further alignment impossible.

[0039] Finally, slide the busbar 4 along the guide structure to complete the installation. After confirming that the alignment is correct, the installer only needs to slide the plug box 1 smoothly into the track formed by the wide bottom edge slot 31 and the narrow bottom edge slot 32 of the busbar. The busbar 4 precisely aligns with the side elastic plug terminals 22 on the plug 2, which have the phase sequence fixed, to form a reliable electrical connection; at the same time, the grounding busbar inside the busbar 4 will also connect with the top elastic plug terminal 23 of the plug 2.

[0040] This embodiment constructs a physical error-proof structure through the asymmetrical wide-narrow fit structure between the interlocking plate 3 and the busbar 4, and the convex-concave positioning structure between the plug pin 2 and the plug box 1. This solution has a simple structure, with all components being common mechanical structures, making it easy to mass-produce. It achieves a significant improvement in safety performance with a relatively small cost increase, effectively preventing serious electrical accidents caused by human negligence.
