[0025] A bus is a power distribution system designed for data center server racks, conforming to the OCP (Open Compute Project) specification. The primary function of a bus is to efficiently and securely transmit power from the power supply rack or PSU (Power Supply Unit) to the individual server nodes within the server rack via copper busbars.

[0026] Busbar devices typically consist of a housing and a busbar module housed within the housing. To accommodate the busbar module inside the housing, the busbar module is generally narrow. However, a narrow busbar module cannot carry a large current, which is not conducive to high current transmission.

[0027] This invention proposes a busbar device designed to enable the busbar device to carry a larger current.

[0028] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the bus device 100 is used to electrically connect to a power source and supply power to a server. The bus device 100 includes a housing assembly 1, a bus module 2, and a plurality of connectors 3. The housing assembly 1 has a length direction, a width direction, and a height direction, and forms a mounting groove 11 with openings at both ends. The bus module 2 is disposed in the mounting groove 11. The bus module 2 includes a main body 21 and an extension 22 connected as one piece along the width direction. The opening width of the housing assembly 1 is smaller than the width of the extension 22 of the bus module 2. The plurality of connectors 3 are spaced apart along the length direction between the bus module 2 and the groove wall of the mounting groove 11, and are used to fix the bus module 2 in the mounting groove 11.

[0029] In this embodiment, the outer casing has an open mounting groove 11 to provide stable mechanical support for the bus module 2. The outer casing is made of an insulating material, such as rigid plastic, to prevent leakage of current through the casing. Both the outer casing and the bus module 2 have several connection holes, and several connectors 3 are respectively inserted through the connection holes to fix the bus module 2 in the receiving cavity of the outer casing, so that the bus module 2 and the outer casing are connected as one unit. Compared with the existing elongated bus module 2, the bus module 2 also includes an extension 22 extending in the width direction. The extension 22 can be integrally formed with the main body 21 and is inserted into the mounting groove 11 through both ends. The extension 22 can enable the bus module 2 to carry a larger current.

[0030] The busbar device 100 proposed in this utility model includes a housing assembly 1, a busbar module 2, and multiple connectors 3. The busbar module 2 is fixed in the mounting groove 11 of the housing assembly 1 by the multiple connectors 3. The busbar module 2 includes a main body 21 and an extension 22. The width of the extension 22 is greater than that of the main body 21, so that the busbar module 2 can carry a larger current, thereby enabling the busbar device 100 as a whole to carry a larger current.

[0031] In an embodiment of this utility model, the two walls of the mounting groove 11 are bent inward to form a shoulder 12. The extension 22 and part of the main body 21 of the busbar module 2 are located between the shoulder 12 and the bottom of the mounting groove 11, and the remaining part of the main body 21 is located between the shoulder 12 and the opening of the mounting groove 11.

[0032] In this embodiment, the outer shell is an integral structure. The two walls of the mounting groove 11 are bent into the mounting groove 11 to form a shoulder 12 to accommodate the extension 22. The extension 22 and part of the main body 21 are located between the shoulder 12 and the bottom. The remaining part of the main body 21 passes through the shoulder 12 and the opening of the mounting groove 11.

[0033] In an embodiment of the present invention, a first stepped surface 211 is formed between the main body 21 and the extension 22, and the first stepped surface 211 is used to abut against the connector joint.

[0034] In this embodiment, the main body 21 and the extension 22 are integrally formed, and a first step surface 211 is formed between the main body 21 and the extension 22. The first step surface 211 can play a limiting role. When the connector is inserted into the mounting groove 11, the connector will abut against the first step surface 211 to prevent the connector from being inserted too deeply.

[0035] In an embodiment of this utility model, the busbar device 100 further includes two grounding bars 4, one of which is disposed on the wall of a mounting groove 11 and located near the opening of the mounting groove 11.

[0036] In this embodiment, the grounding strip 4 is a conductive component used to establish a reliable grounding path. Specifically, it can be implemented using copper strip or tin-plated copper strip. It is mechanically fixed to the side wall of the mounting groove 11 and positioned close to the groove opening of the mounting groove 11 to form an electrical connection with the external grounding system, which can effectively eliminate the risk of leakage current accumulation. The two grounding strips 4 are symmetrically arranged on the outer edges of the two side plates 14 to form double grounding protection, which can quickly conduct abnormal charges to the ground.

[0037] In an embodiment of this utility model, the busbar device 100 further includes a handle 5, which is disposed on the outer surface of the housing assembly 1.

[0038] In this embodiment, the number of handles 5 is at least one, such as one, two, or more. The handles 5 can be made of metal, such as aluminum alloy, or of rigid plastic. When the manifold device 100 needs to be moved, workers can use the handles 5 to move it, which makes it easier to apply force and saves effort, reducing safety hazards.

[0039] In an embodiment of this utility model, there are multiple handles 5, which are evenly distributed along the length direction on the outer surface of the housing assembly 1.

[0040] In this embodiment, there are multiple handles 5, which are evenly distributed along the length of the busbar device 100, allowing multiple operators to simultaneously move the busbar device 100 from one side, further saving manpower and reducing safety hazards. In a preferred embodiment, multiple handles 5 are provided on the outer surfaces of both side plates 14, allowing at least two operators to simultaneously move the busbar module 2 from opposite sides, further saving manpower and reducing safety hazards.

[0041] In an embodiment of this utility model, the ratio between the width of the opening of the housing assembly 1 and the bottom of the housing assembly 1 is greater than or equal to 0.5 and less than or equal to 0.7.

[0042] In this embodiment, the ratio between the width of the opening of the housing assembly 1 and the bottom of the housing assembly 1 is greater than or equal to 0.5 and less than or equal to 0.7, for example, 0.5, 0.6, 0.7, or any value within the above range. The ratio between the width of the opening of the housing assembly 1 and the bottom of the housing assembly 1 should not be too large, as this would result in the bottom not being wide enough, and consequently, the width of the extension 22 would be insufficient to carry a large current. It should also not be too small, as this would make it difficult for the main body 21 of the busbar module 2 to be inserted, leading to installation difficulties.

[0043] This utility model also proposes a bus device 100 for electrical connection with a power source and for supplying power to a server. The bus device 100 includes a housing assembly 1, a bus module 2, and multiple connectors 3. The housing assembly 1 has a length direction, a width direction, and a height direction. The housing assembly 1 includes a base 13 and two side plates 14. Each side plate 14 includes a first part 141 and a second part 143. A second stepped surface 142 is formed between the first part 141 and the second part 143. The base 13 is U-shaped, and the second parts 143 of the two side plates 14 are... The busbar module 2 is connected to both sides of the base 13, and the base 13 and the two side plates 14 enclose and form a mounting groove 11 with through ends and openings. The busbar module 2 is disposed in the mounting groove 11. The busbar module 2 includes a main body 21 and an extension 22 connected as one piece along the height direction. The main body 21 is located between the two side plates 14, and the extension 22 and the rest of the main body 21 are located in the base 13. A plurality of connectors 3 are spaced apart along the length direction between the busbar module 2 and the groove wall of the mounting groove 11 for fixing the busbar module 2 in the mounting groove 11.

[0044] In this embodiment, the outer casing is divided into two parts, including a base 13 and two side plates 14. Each side plate 14 has a first part 141 and a second part 143 that are stepped. The second part 143 of each side plate 14 is connected to both sides of the base 13. The base 13 and the two side plates 14 together form a mounting groove 11 with through-ends and openings. The cross-section of the mounting groove 11 is convex. Compared with the existing elongated busbar module 2, the busbar module 2 also includes an extension 22 extending along the width direction. The extension 22 can be integrally formed with the main body 21. It passes through the two ends of the mounting groove 11 and enters the mounting groove 11. The extension 22 can enable the busbar module 2 to carry a larger current.

[0045] During installation, first connect part of the main body 21 and the first part 141 of the two side plates 14 into one piece, then put the base 13 on the outside of the remaining main body 21 and extension 22, and finally connect and fix the base 13 to the outside of the remaining main body 21 and extension 22, thus completing the connection between the busbar module 2 and the housing.

[0046] In an embodiment of this utility model, the base 13 and the second part 143 of the two side plates 14 are riveted together.

[0047] In this embodiment, the base 13 and the second part 143 of the two side plates 14 are respectively provided with multiple through holes. Multiple rivets pass through the multiple through holes to connect the base 13 and the two side plates 14 and enclose them to form the mounting groove 11.

[0048] In an embodiment of this utility model, the base 13 and the second part 143 of the two side plates 14 are welded together.

[0049] In this embodiment, the base 13 and the second part 143 of the two side plates 14 are welded together to make the shell a whole, so that the connection strength between the two is better.

[0050] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
