[0028] 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.
[0029] Existing bus modules capable of high current transmission are not compact enough and occupy too much space.
[0030] This invention proposes a bus module designed to achieve high current transmission through a compact structure.
[0031] Please see Figures 1 to 5 In one embodiment of this utility model, the bus module 100 includes an insulating shell 1, a first bus 2, a second bus 3, and a first insulating sheet 4. The insulating shell 1 has a length direction, a width direction, and a height direction. The first bus 2 is disposed inside the insulating shell 1. Two first convex walls 21 are protruding from both sides of the first bus 2 in the width direction. The two first convex walls 21 are spaced apart and extend along the length direction, forming a first slot with the side surface. The second bus 3 is disposed inside the insulating shell 1. Two second convex walls 21 are protruding from both sides of the second bus 3 in the width direction. The two second convex walls 21 are spaced apart and extend along the length direction, forming a second slot with the side surface. The first insulating sheet 4 is sandwiched between the first bus 2 and the second bus 3. The first bus 2, the second bus 3, and the first insulating sheet 4 are arranged along the height direction of the insulating shell 1.
[0032] In this embodiment, the insulating shell 1 is made of an insulating material, such as rigid plastic. The size and shape of the first busbar 2 are the same as those of the second busbar 3, and the material is brass or aluminum, etc. The main body is a long strip plate. The first convex wall 21 is a convex plate structure extending along the width direction of the first busbar 2, and the second convex wall 21 is a convex plate structure extending along the width direction of the second busbar 3. The two first convex walls 21 enclose to form a first slot, and the two second convex walls 21 enclose to form a second slot. The first slot and the second slot are used for plugging and connecting with the connector and for electrical connection with the first busbar 2 and the second busbar 3. The material of the first insulating sheet 4 can be polyimide film, which serves to electrically isolate the first busbar 2 and the second busbar 3. The first convex wall 21 and the second convex wall 21 protruding from the two side surfaces of the first busbar 2 and the second busbar 3 directly plug into the electrical connector. Compared with the conventional slots formed on the shell, the structure is more compact, and the compact structure achieves the effect of high current transmission.
[0033] The bus module 100 proposed in this utility model achieves a compact layout and efficient power distribution through the first bus 2, the second bus 3 and the first insulating sheet 4 arranged along the height direction, combined with the structural design of the convex wall 21 and the slot. It has the advantages of compact structure, space saving, easy installation and maintenance, and improved safety and stability.
[0034] In an embodiment of this utility model, the insulating shell 1 includes an upper insulating plate 11, a lower insulating plate 12, and two side insulating plates 13. One side insulating plate 13 connects one side of the upper insulating plate 11 in the length direction and one side of the lower insulating plate 12 in the length direction. The upper insulating plate 11, the lower insulating plate 12, and the two side insulating plates 13 enclose a cavity, and the cavity has elongated openings on both sides in the width direction.
[0035] In this embodiment, the upper insulating plate 11 and the lower insulating plate 12 are connected by a side insulating plate 13 to form a closed cavity. This cavity has elongated openings on both sides in the width direction. During assembly, the first busbar 2, the second busbar 3, and the first insulating sheet 4 are housed within the cavity, with their width sides exposed through the openings. This allows external conductive connectors to be inserted through the elongated openings and electrically connected to the first busbar 2 and the second busbar 3, thus achieving current transfer through the busbar module 100. The elongated openings allow multiple external conductive connectors to be simultaneously plugged into the busbar module 100, achieving current distribution to multiple electrical components.
[0036] In an embodiment of this utility model, the cavity has elongated openings only on opposite sides in the width direction.
[0037] In this embodiment, a conventional bus module 100 has openings in multiple directions to facilitate external connections, resulting in a loose overall structure and a large space occupation for the insulating shell 1. By limiting the openings to only be distributed on both sides of the width direction, the electrical connection requirements for inserting external conductive connectors into slots are met, and the space layout is optimized by reducing unnecessary openings, making the overall structure of the bus module 100 more compact.
[0038] In an embodiment of this utility model, the bus module 100 further includes a connecting part 5, which is disposed on one side surface of the first bus 2 and / or the second bus 3 in the width direction, and the connecting part 5 is rectangular.
[0039] In this embodiment, the bus module 100 further includes a connecting portion 5, which is disposed on one side surface of the first bus 2 and / or the second bus 3 in the width direction. The connecting portion 5 is used to connect the branch bus 6 or other conductive structures to achieve the effect of current shunting of the bus module 100, so that the bus module 100 as a whole can carry a larger current. It can be understood that the connecting portion 5 can be a rectangular block structure, respectively embedded between the two first protruding walls 21 of the first bus 2 and the two second protruding walls 21 of the second bus 3. The rectangular block structure connecting portion 5 is electrically connected to the branch bus to achieve the effect of current shunting, so that the bus module 100 can carry a larger current. Alternatively, the connecting portion 5 can be a rectangular connecting groove formed on one side surface of the first bus 2 and one side surface of the second bus 3. The branch bus is inserted into the rectangular connecting groove and electrically connected to the first bus 2 and the second bus 3 to achieve the effect of current shunting, so that the bus module 100 can carry a larger current.
[0040] In an embodiment of this utility model, the connecting part 5 is a solid block, the connecting part 5 is sandwiched between two convex walls 21, and the connecting part 5 is provided with a through hole.
[0041] In this embodiment, the connecting part 5 is a solid block, specifically a rectangular block structure. There are two solid blocks, which are respectively embedded between the two first protruding walls 21 of the first busbar 2 and the two second protruding walls 21 of the second busbar 3. The connecting part 5 has a through hole for the connector to pass through, so as to connect the branch busbar to the connecting part 5 through the connector. The solid block structure connecting part 5 is electrically connected to the branch busbar to achieve the effect of current shunting, so that the busbar module 100 can carry a larger current.
[0042] In an embodiment of this utility model, the bus module 100 further includes a branch bus 6, which includes a third bus 61, a fourth bus 62, and a second insulating sheet 63 sandwiched between them. The end faces of the third bus 61 and the fourth bus 62 facing the first bus 2 each have a protruding tongue 611, and the two protruding tongues 611 are electrically connected to the first bus 2 and the second bus 3 via the connecting part 5.
[0043] In this embodiment, the bus module 100 further includes a branch bus 6, which includes a third bus 61, a fourth bus 62, and a second insulating sheet 63 sandwiched between them. The branch bus 6 is used to shunt current so that the bus module 100 can carry a larger current. Both the third bus 61 and the fourth bus 62 have a protruding tongue 611 on their end faces facing the first bus 2. The two protruding tongues 611 are electrically connected to the first bus 2 and the second bus 3 through a connecting part 5. When the connecting part 5 is a solid block structure, the two protruding tongues 611 and the solid block structure have connecting holes. A connector passes through the connecting holes to connect the two protruding tongues 611 to the solid block, thereby realizing the electrical connection between the third bus 61 and the first bus 2, and the electrical connection between the fourth bus 62 and the second bus 3. The material of the second insulating sheet 63 can be polyimide film or silicone, etc., to achieve electrical isolation between the third bus 61 and the fourth bus 62. The current path of the bus module 100 includes a first bus 2-connection part 5-third bus 61 and a second bus 3-connection part 5-fourth bus 62, so as to realize the electrical conduction on both the positive and negative sides.
[0044] In embodiments of this utility model, the entire tongue 611 of the third bus 61 is exposed to the first bus 2 or is not covered by the first bus 2; the entire tongue 611 of the fourth bus 62 is exposed to the second bus 3 or is not covered by the second bus 3.
[0045] It is understood that a surface of one tongue 611 facing another tongue 611 is connected to a surface in the thickness direction of the first busbar 2 or a surface in the thickness direction of the second busbar 3.
[0046] In this embodiment, one surface of one tongue 611 facing another tongue 611 is connected to a surface in the thickness direction of the first busbar 2 or a surface in the thickness direction of the second busbar 3. That is, the two tongues 611 enclose an open receiving cavity between the end face of the third busbar 61 and the end face of the fourth busbar 62. One side wall of the receiving cavity is connected to a surface in the thickness direction of the first busbar 2, and the other side wall of the receiving cavity is connected to a surface in the thickness direction of the second busbar 3. The two tongues 611 are disposed on the outer surfaces of the first busbar 2 and the second busbar 3, clamping them in the receiving cavity. Both tongues 611 and the solid block are provided with connecting holes. The connector passes through several connecting holes to connect the two tongues 611 to the solid block, thereby connecting the branch busbar 6, the first busbar 2 and the second busbar 3 into one unit, improving the connection strength.
[0047] In an embodiment of this utility model, the first insulating sheet 4 is partially exposed in the insulating shell 1 and is located between the two protruding tongues 611.
[0048] In this embodiment, the first insulating sheet 4 extends beyond the coverage area of the insulating shell 1 in the width direction, so that its edge area is partially exposed from the opening on the side of the insulating shell 1. When the protrusion 611 of the branch bus 6 is inserted into the slot of the main bus and contacts the connection part 5, the exposed part of the first insulating sheet 4 is located exactly in the gap between the two protrusions 611, thereby forming an additional insulating barrier in the docking area of the branch bus 6 with the first bus 2 and the second bus 3.
[0049] In an embodiment of this utility model, the first insulating sheet 4 partially overlaps with the tongue 611 in the width direction.
[0050] In this embodiment, the first insulating sheet 4 does not extend into the space between the two protruding tongues 611, but only partially overlaps with the protruding tongues 611 in the width direction. The two protruding tongues 611 clamp the first busbar 2, the first insulating sheet 4, and the second busbar 3, and partially overlap with the first insulating sheet 4 in the width direction, thereby improving the connection stability between the protruding tongues 611 and the first busbar 2 or the second busbar 3.
[0051] In an embodiment of the present invention, at least a portion of the end face of the third busbar 61 abuts against the side surface of the connecting portion 5.
[0052] In this embodiment, the end face of the third bus 61 at least partially abuts against the side surface of the connecting part 5. Since the third bus 61 and the fourth bus 62 have the same shape and structure, the end face of the fourth bus 62 also at least partially abuts against the side surface of the connecting part 5. This connection method can increase new current transmission paths, including four current paths: first bus 2-third bus 61, first bus 2-connecting part 5-third bus 61, second bus 3-fourth bus 62 and second bus 3-connecting part 5-fourth bus 62, thereby increasing the overall current carrying capacity of the bus module 100 and achieving the effect of high current transmission.
[0053] 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.
