[0040] Please refer to Figure 1 and Figure 2 , which is a preferred embodiment of the present invention. The hot-swap system includes the above-mentioned track-type busbar 10, tapping unit 20 and fixing member 30. The track-type busbar 10 is detachably mounted on the fixing member 30, and the tapping unit 20 is detachably mounted on the track-type busbar 10. The track-type busbar 10 is applicable to both AC busbars and DC busbars.

[0041] Please refer to Figure 2 , which is a preferred embodiment of the present invention. The track-type busbar 10 includes: a housing 100 with a socket 130 on one side; a plurality of cavity 110 arranged side by side, with a notch 120 on the side of the cavity 110 facing the socket 130; a long strip-shaped U-shaped busbar 400 installed in the cavity 110, with an interface 410 on the side facing the socket 130.

[0042] The track-type busbar trunking 10 adopts U-shaped busbars 400 arranged side by side, allowing the tapping unit 20 to connect and draw power through direct insertion at any position, and supporting the insertion of the tapping unit 20 when the track-type busbar trunking 10 is energized. This design greatly improves the flexibility and safety of the track-type busbar trunking 10. In addition, due to the larger cross-sectional area and surface area of the U-shaped busbar 400, the track-type busbar trunking 10 has higher short-circuit withstand performance and lower energy consumption while maintaining a lower operating temperature rise. The track-type busbar trunking 10 can better meet the strict requirements of the data center computer room for temperature control and energy consumption management, providing a strong guarantee for the stable operation of the data center.

[0043] As Figure 1-3 shown, the track-type busbar trunking 10 mainly includes structures such as a housing 100, a cover plate 200, a busbar insulating sleeve 300, a U-shaped busbar 400, and an end cover 600. The following will further introduce each of the above components in detail.

[0044] As Figure 3 and Figure 4 shown, the housing 100 is generally oblong in shape, with stable and reliable structural strength, and has good impact resistance and pressure resistance. One side of the housing 100 is provided with a socket 130 extending in the width direction. A plurality of cavity 110 for installing the U-shaped busbar 400 are provided in the housing 100, and the cavity 110 extends along the length direction of the housing 100. A plurality of cavity 110 are arranged side by side in the width direction of the housing 100, and a reasonable spacing is set between each cavity 110, so that the electrical clearance between each phase of the U-shaped busbar 400 meets the safety standards. The side of the cavity 110 facing the socket 130 is provided with a notch 120. The housing 100 can be made of aluminum alloy, or steel, or other metal materials or alloy materials, and can also be made of non-metal materials.

[0045] As Figure 4 shown, the track-type busbar trunking 10 further includes a plurality of partitions 140. A plurality of the partitions 140 are arranged side by side in the width direction of the housing 100, and the cavity 110 is formed between two adjacent partitions 140. A plurality of support plates 150 are fixedly provided on the partition 140, and the support plates 150 are perpendicular to the partition 140.

[0046] As Figure 5As shown, the track type busbar trunking 10 further includes a busbar insulating sleeve 300, and the busbar insulating sleeve 300 is integrally strip-shaped. The busbar insulating sleeve 300 is sleeved between the U-shaped busbar 400 and the slot cavity 110 to further increase the creepage distance and achieve insulation protection. The busbar insulating sleeve 300 is also U-shaped and is in the same direction as the notch 120 of the U-shaped busbar 400. A flare 310 is provided on the side of the busbar insulating sleeve 300 facing the socket 130, and the size of the minimum opening position of the flare 310 is adapted to the size of the interface 410. Specifically, the minimum opening position of the flare 310 of the busbar insulating sleeve 300 is slightly larger than the notch 120 of the U-shaped busbar 400, which does not affect the insertion of the pin 23 of the tapping unit 20 (see Figure 2 ) and can fix the U-shaped busbar 400 in the busbar insulating sleeve 300 at the same time. A clamping groove 320 is provided at one end of the busbar insulating sleeve 300 close to the flare 310, and the clamping groove 320 is clamped on the support plate 150 to form the flare 310. The distance between the two clamping grooves 320 of the busbar insulating sleeve 300 matches the size of the notch 120, so that the U-shaped busbar 400 protected by the busbar insulating sleeve 300 can be reliably fixed in the slot cavity 110.

[0047] The U-shaped busbar 400 is also integrally strip-shaped and is installed in the busbar insulating sleeve 300. The U-shaped busbar 400 is provided with an interface 410 for electrically connecting with the tapping unit 20, and the opening direction of the interface 410 is the same as the opening direction of the socket 130. The interfaces 410 of multiple U-shaped busbars 400 face the same direction, which is convenient for the pins 23 of the tapping unit 20 (see Figure 2 ) to be directly inserted. A chamfer 411 is provided inside the interface 410, which can cooperate with the flare 310 of the busbar insulating sleeve 300 to facilitate the guiding insertion of the pin 23 of the tapping unit 20 into the U-shaped busbar 400. The U-shaped busbar 400 can be a copper conductor, an aluminum conductor, or other conductive materials.

[0048] In another embodiment of the present application, as Figure 5 shown, the track type busbar trunking 10 further includes a cover plate 200. The cover plate 200 is detachably installed at the socket 130. Specifically, clamping openings 160 are provided at both ends of the socket 130 side of the housing 100, and clamping buckles 210 are provided at the edge of the cover plate 200. The clamping openings 160 and the clamping buckles 210 are matched, and the clamping buckles 210 are detachably clamped in the clamping openings 160. The cover plate 200 can effectively protect the busbar trunking from foreign objects invading the socket side and causing safety accidents or performance failures when the tapping unit is not installed.

[0049] On the middle parts of the left and right sides of the housing 100, there are wire grooves 170 for accommodating cables. The wire grooves 170 are provided with wire groove covers 180. The arrangement of the wire groove covers 180 on the wire grooves 170 can effectively protect the cables in the grooves and also make the appearance of the housing 100 flat and beautiful.

[0050] As Figure 5 shown, on the outer side wall of the housing 100 away from the socket 130, there is fixedly provided a hoisting groove rib 800 for connecting with the fixing component 30. The hoisting groove rib 800 is designed to support both the horizontal installation of the track type busbar 10 as Figure 1 shown and the vertical installation as Figure 6 , Figure 7 shown. The flexible installation method can meet the different needs of customers. The combination of the wire groove 170 and the hoisting groove rib 800 provides support for the vertical installation and reverse horizontal installation of the track type busbar 10. In this way, the track type busbar 10 will have four installation directions: upper horizontal, lower horizontal, left vertical, and right vertical, bringing more flexibility to the practical application of the track type busbar 10.

[0051] Looking back Figure 2 , on both sides of the socket 130, there are respectively a first card slot 191 and a second card slot 192 for detachably connecting with the tapping unit 20. The first card slot 191 is circular, and the second card slot 192 is rectangular. The first card slot 191 and the second card slot 192 can lock and fix the pluggable tapping unit 20 to ensure the stability during the operation of the track type busbar 10. On the tapping unit 20, there are fixed clasps 21 and movable clasps 22 corresponding to the first card slot 191 and the second card slot 192. The fixed clasp 21 is in an inverted circular shape and extends outward, matching the first card slot 191. So that no matter the tapping unit 20 is installed horizontally or vertically, the fixed clasp 21 can act as a hinge rotating shaft to rotate the tapping unit 20, facilitating the installation of the tapping unit 20. The movable clasp 22 can be pulled open by hand. After the tapping unit 20 rotates in place, the movable clasp 22 can be reset and snapped into the second card slot 192 to achieve a perfect snap fit between the movable clasp 22 and the second card slot 192.

[0052] As Figure 8 shown, both ends of the housing 100 are provided with ports 500. As Figure 3 and Figure 9As shown, an end cover 600 is sleeved on the port 500. The end cover 600 is detachably installed at the port 500 through fasteners such as screws. The end cover 600 is configured to fit the outer shape of the port 500 and is made of an insulating material. A perforation 610 and a boss 620 are provided in the middle of the end cover 600. The number of the perforations 610 corresponds to the number of the U-shaped busbars 400, so that the U-shaped busbars 400 can pass through the perforations 610. The size of the perforations 610 is only suitable for the U-shaped busbars 400 to pass through, but not for the busbar insulation sleeves 300, ensuring that only the U-shaped busbars 400 used for connection protrude through the end cover 600 as a whole. A boss 620 with a certain length also extends from the perforations 610 to increase the creepage distance between the U-shaped busbars 400.

[0053] The U-shaped busbars 400 are in a compressed state at the port 500 part, that is, the width of the interfaces 410 of the U-shaped busbars 400 is pressed to zero, so that the two ends of the track-type busway 10 can be firmly fastened when installing and locking the connectors.

[0054] The track-type busway 10 further includes an end cover gasket 710 and an end-ring gasket 720. Among them, the end cover gasket 710 is installed between the housing 100 and the end cover 600, and the protection level of the connection part can be effectively improved after fastening the end cover 600. The end-ring gasket 720 is arranged on the outer contour surface of the end cover 600. Specifically, the end-ring gasket 720 is a ring-shaped gasket with single-sided adhesive, and the ring-shaped gasket is of the same width as the outer edge contour of the end cover 600. When the track-type busway 10 and the connector are installed together, the installation gap can be sealed to further improve the protection level.

[0055] The described track-type busway 10 has high short-circuit withstand performance, a conductor cross-sectional area large enough, and reliable fastening, enabling the track-type busway 10 to have better electrical safety performance than that of other manufacturers. Good temperature rise and a larger conductor cross-sectional area result in a low overall resistance of the track-type busway 10, and the current heat effect generated during operation is also much lower than the reference value required by the national standard, making it more in line with the application requirements of the data center. The described track-type busway 10 also has an unfixed socket position and a flexible plugging method. The through-length U-shaped busbar 400 allows any section of the track-type busway 10 to insert the tapping unit 20 according to the on-site environmental requirements and neatness and aesthetics. The track-type busway 10 can also achieve equipotential hot plugging, and the track-type busway 10 does not need to be powered off to insert the tapping unit 20. The sufficient phase-to-phase electrical isolation of the track-type busway 10 ensures that even the arc phenomenon generated during hot plugging will not affect the adjacent phase. The oblong-shaped housing 100 has a stable structure, good impact resistance and pressure-bearing performance, greatly increasing the impact resistance on the side and the pressure-bearing performance during vertical installation. Sealing protection measures are adopted between all components connected to the housing 100, and a cover gasket 710 and an end-ring gasket 720 are provided, with high overall protection performance. The described track-type busway 10 has a multi-directional installation method. Compared with the prior art which only has a flat installation method, the track-type busway 10 can adopt left and right vertical installation or front and back flat installation methods according to the on-site space and layout aesthetics requirements.

[0056] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, many changes can be made in the specific implementation manners and application scopes according to the idea of the present invention. As long as these changes do not depart from the concept of the present invention, they all fall within the protection scope of the present invention.
