Description

Technical Field

[0001] This utility model relates to the field of busbar docking technology, and more specifically to a high-current busbar docking coupling device for data centers. Background Technology

[0002] With the rapid development of artificial intelligence and cloud computing technologies, the demand for computing power in data centers is growing exponentially, leading to a significant increase in power load. The current rating of traditional data center bus designs can no longer meet the needs of high-density computing scenarios, and there is an urgent need to develop power supply solutions that support higher current.

[0003] A search revealed Chinese patent CN221353224U, which discloses a track bus docking coupling device for a high-current data center. This device facilitates the installation of the coupler by using an upper and lower docking type coupler, and also sets a PE jumper on the outside of the coupler to connect the main and auxiliary PE busbars of the track bus, thereby ensuring the effectiveness of the PE busbars and improving the safety of the coupler connection. However, since the track busbar models vary, the distance between the copper busbars inside will also vary. The position of the alloy conductor in the coupler is fixed, which greatly reduces the applicability of the device. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a data center high-current bus docking coupling device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a data center high-current bus docking coupling device, including a track bus, the ends of which are connected to each other by two couplers that open and close vertically. Each of the two couplers has two symmetrical sliding openings on one side. Each of the two sliding openings on the same coupler has multiple first screws, and the multiple first screws in the two sliding openings correspond one-to-one. The bottom ends of the multiple sets of corresponding first screws are threaded to a U-shaped clamp. A U-shaped groove is opened in the middle of the inner wall of the U-shaped clamp. A U-shaped conductor that fits its shape is provided in the U-shaped groove. Connecting rings are fixedly connected to both sides of the coupler. The two connecting rings corresponding to the upper and lower ends of the two couplers have second screws for fixing the two connecting rings. Tensioning components for tightening the two track buses are provided on both sides of the two track buses.

[0006] As a further embodiment of this utility model, the tensioning assembly includes two side protrusions fixedly connected to the ends of two rail busbars. Each of the side protrusions has two square holes. A U-shaped pull rod is slidably connected to the two square holes on the two side protrusions on the same side. The inner walls of the U-shaped pull rods on both sides have slots. A card plate is slidably connected to the two slots. A screw hole is provided on the card plate. A tensioning screw is threaded into the screw hole, and one end of the tensioning screw contacts one side of one of the side protrusions.

[0007] As a further embodiment of this utility model, two symmetrical positioning grooves are provided on one inner wall of each of the two couplers, and two positioning blocks are fixedly connected to one outer wall of each of the multiple U-shaped clamps. The distance between the two positioning blocks is equal to the distance between the two positioning grooves, and the two positioning blocks slide in the two positioning grooves respectively.

[0008] As a further embodiment of this utility model, a convex ring is fixedly connected to the bottom of the connecting ring on the upper coupler, and the inner diameter of the convex ring is the same as that of the inner ring of the connecting ring. A ring groove that cooperates with the convex ring is opened on the upper surface of the connecting ring on the lower coupler.

[0009] As a further embodiment of this utility model, the end of the U-shaped pull rod is provided with fixing screws for fixing the card plate.

[0010] As a further embodiment of this invention, the U-shaped clamp is made of insulating ceramic, and the coupler has heat dissipation holes evenly distributed on it for heat dissipation.

[0011] As a further embodiment of this utility model, two U-shaped protective shells that open and close vertically are fixedly connected to two adjacent side protrusions on both sides of the two track busbars.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model makes multiple U-shaped clamps slidable by providing a sliding opening, which can fix copper busbars with different spacing on different track busbars, thus increasing the adaptability of the device.

[0014] 2. By using the positioning groove and positioning block together, this utility model ensures that when the U-shaped clamp below it is moved by the first screw, the positioning block always slides in the positioning groove, preventing the U-shaped clamp from tilting during the movement, which would affect the subsequent work of fastening it to the copper busbar.

[0015] 3. This utility model, through the tensioning component, applies constant pressure to force the copper busbar contact surfaces to fit tightly together, thus avoiding gaps between the copper busbars at the ends of the two track busbars during docking, which would affect the conduction of current.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-5This utility model provides a high-current busbar docking coupling device for a data center, including a track busbar 1. The ends of the track busbar 1 are connected to each other by two couplers 2 that open and close vertically. Each of the two couplers 2 has two symmetrical sliding ports 5 on one side. Each of the two sliding ports 5 on the same coupler 2 has multiple first screws 6, and the multiple first screws 6 in the two sliding ports 5 correspond one-to-one. The bottom ends of the multiple sets of corresponding first screws 6 are threaded to U-shaped clamps 7. The middle part of the inner wall of the U-shaped clamps 7 has a U-shaped groove 14. The U-shaped groove 14 has a U-shaped conductor 15 that fits its shape. Both sides of the coupler 2 are fixedly connected to connecting rings 8 by bolts. The two corresponding connecting rings 8 of the two couplers 2 have second screws 11 for fixing the two connecting rings 8. Both sides of the two track busbars 1 are provided with tensioning components to tighten the two track busbars 1. The two adjacent side protrusions 3 on both sides of the two track busbars 1 are connected by screws. The device is fixedly connected to two U-shaped protective shells 4 that open and close vertically. Two symmetrical positioning grooves 12 are provided on the inner wall of one side of each of the two couplers 2. Two positioning blocks 13 are fixedly connected to the outer wall of one side of each of the multiple U-shaped clamps 7 by bolts. The distance between the two positioning blocks 13 is equal to the distance between the two positioning grooves 12. The two positioning blocks 13 slide in the two positioning grooves 12 respectively. When it is necessary to connect the track busbars 1, the copper busbars at the ends of the two track busbars 1 are connected first. Then, the two couplers 2 are fastened to the copper busbars of the track busbars 1 that are connected. At the same time as fastening, the position of the multiple U-shaped clamps 7 is adjusted by the first screw 6 so that they can be accurately fastened to the multiple connected copper busbars. After the two couplers 2 are fastened, the connecting ring 8 on the side is fixed by the second screw 11. By providing the sliding mouth 5, the multiple U-shaped clamps 7 are made to be slidable. They can be fixed when facing copper busbars with different spacing on different track busbars 1, which increases the adaptability of the device.

[0024] In this invention, the tensioning assembly includes two side protrusions 3 fixedly connected to the ends of two track busbars 1 by bolts. Each side protrusion 3 has two square holes 16. A U-shaped pull rod 17 is slidably connected within the two square holes 16 on the two side protrusions 3 on the same side. The open ends of the inner walls of the U-shaped pull rod 17 on both sides have slots 18. A retaining plate 19 is slidably connected within the two slots 18. A screw hole 20 is provided on the retaining plate 19, and a tensioning screw 21 is threaded into the screw hole 20. One end of the tensioning screw 21 contacts one side of one of the side protrusions 3. After the two couplers 2 are fixed, the U-shaped pull rod 17 on the side is simultaneously passed through the square hole 16 on one side protrusion 3 through the square hole 16 on the other side protrusion 3. Then, the retaining plate 19 is embedded into the two slots 18. Inside, the clamping plate 19 is fixed by the fixing screw, and then the tensioning screw 21 is installed into the screw hole 20 and rotated. After one end of the tensioning screw 21 contacts the side protrusion 3, it continues to rotate, so that the two track busbars 1 are brought closer to each other. After their ends are in close contact, the tensioning is completed. Through the tensioning component, a constant pressure is applied to force the copper busbar contact surfaces to fit tightly, avoiding gaps between the copper busbars at the ends of the two track busbars 1 during docking, which would affect the conduction of current. Through the cooperation of the positioning groove 12 and the positioning block 13, when the U-shaped clamp 7 below it is moved by the first screw 6, the positioning block 13 always slides in the positioning groove 12, preventing the U-shaped clamp 7 from tilting during the movement, which would affect the subsequent work of fastening it to the copper busbar.

[0025] In this invention, a convex ring 9 is welded to the bottom of the connecting ring 8 on the upper coupler 2, and the inner diameter of the convex ring 9 is the same as that of the inner diameter of the connecting ring 8. A ring groove 10 is provided on the upper surface of the connecting ring 8 on the lower coupler 2 to cooperate with the convex ring 9. The end of the U-shaped pull rod 17 is provided with a fixing screw for fixing the clamping plate 19. The U-shaped clamp 7 is made of insulating ceramic. Heat dissipation holes for heat dissipation are evenly distributed on the coupler 2. After the two track busbars 1 are tightened, multiple first screws 6 are rotated by a tool to make the inner wall of the U-shaped clamp 7 in close contact with the copper busbars at the ends of the two track busbars 1.

[0026] The use of this utility model involves the following steps:

[0027] S1: When it is necessary to connect the track busbars 1, first connect the copper busbars at the ends of the two track busbars 1, and then fasten the two couplers 2 onto the copper busbars of the track busbars 1 that are connected. While fastening, adjust the position of the multiple U-shaped clamps 7 with the first screw 6 so that they can be accurately fastened onto the multiple connected copper busbars. After the two couplers 2 are fastened, fix the side connecting ring 8 with the second screw 11.

[0028] S2: After fixing the two couplers 2, simultaneously pass the U-shaped pull rod 17 on the side through the square hole 16 on one side protrusion 3 and the square hole 16 on the other side protrusion 3. Then, insert the clamping plate 19 into the two slots 18 and fix the clamping plate 19 with the fixing screw. Then, install the tensioning screw 21 into the screw hole 20 and continue to rotate. After one end of the tensioning screw 21 contacts the side protrusion 3 that is close to it, continue to rotate so that the two track busbars 1 come closer to each other. After their ends are in close contact, the tensioning is completed.

[0029] S3: After tightening the two track busbars 1, use a tool to rotate multiple first screws 6 so that the inner wall of the U-shaped clamp 7 is in close contact with the copper busbars at the ends of the two track busbars 1.
