Referring to Figure 1, in this embodiment, the cabinet power bridging structure is applied to the power bridging between two cabinets 10 and 10a. The two cabinets 10 and 10a in Figure 1 have the same or similar structures; the following description focuses on the same or similar parts of cabinet 10. Figure 2 is an exploded perspective view of the cabinet power bridging structure and cabinet of the first embodiment disclosed herein.

[0023] Referring to Figure 2, in this embodiment, the cabinet 10 includes a cuboid cabinet that can house multiple electronic units 30. This disclosure does not limit the form of the electronic units 30; for example, as shown in this embodiment, these electronic units 30 include a server unit 31, a power supply unit 32, and a backup battery unit (BBU). The server unit 31 may include components such as a microprocessor, digital circuitry, analog circuitry, memory, and storage devices. The power supply unit 32 may include at least one of components such as an AC / DC conversion circuit, a power factor correction circuit, a DC / DC conversion circuit, and a battery. The power supply unit 32 may be coupled to an AC input power supply, a DC input power supply, other power supply units 32a, and / or the backup battery unit 33 to supply power to the server unit 31. The cabinet 10 includes a power bus 20 disposed on the power distribution side 11 of the cabinet, as shown in Figure 1, with both ends of the power bus 20 fixed to the upper and lower ends of the cabinet, respectively.

[0024] Referring to Figures 1 and 2, the cabinet power bridging structure includes a plurality of power buses (20, 20a) disposed in each cabinet (10, 10a) and at least one power bus bridging device 50. The power bus bridging device 50 is used to connect the power bus 20 located in one cabinet 10 to the power bus 20a located in another cabinet 10a, thereby achieving power transmission and scheduling between the two cabinets (10, 10a). In this embodiment, the axial direction of the power bus 20 is arranged parallel to the power distribution side 11 of the cabinet and is substantially perpendicular to the plane on which the cabinet 10 is placed; the power bus bridging device 50 is connected to the side of the aforementioned two power buses (20, 20a) that is farther away from the cabinet, and the axial direction of the power bus bridging device 50 is substantially parallel to the plane on which the cabinet 10 is placed. In other embodiments, the power bus 20 and the cabinet 10, the plane on which the cabinet 10 is placed, and the power bus bridging device 50 can also be configured with other suitable connection angles.

[0025] In some embodiments, the power supply unit 32 includes a battery or other power storage device. Therefore, in addition to supplying power to the server unit 31 and / or other power supply units 32, the power supply unit 32 may also perform only power storage functions at certain times, such as charging only the battery of the power supply unit 32 without supplying power to the server unit 31, other power supply units, and / or battery backup unit 33. The battery backup unit 33 may perform either power supply or power storage functions depending on the settings.

[0026] Figure 3 is a perspective view of an embodiment of the power bus 20. Referring to Figures 2 and 3, the power bus 20 includes a bus side 21 facing the cabinet 10 and a bridging side 22 away from the cabinet 10. Electronic units 30 are connected to the bus side 21 of the power bus 20. In this embodiment, the power bus 20 is vertically configured, and a plurality of electronic units 30 are provided inside the cabinet 10. For example, the plurality of electronic units in the embodiment of Figure 2 includes a server unit 31 and two power supply units (32, 32a). The electronic units 30 are stacked on the cabinet of the cabinet 10, and the side of the electronic unit 30 facing the power bus 20 includes a power connector 34 to connect to the power bus 20.

[0027] The power bus 20 in Figure 3 includes conductive busbars (23a, 23b), with an insulator 23c sandwiched between the conductive busbars (23a, 23b).

The connector 35 includes a pair of jaws 37. The two ends of each conductive arm 36 are respectively connected to the connector 35 and other components of the electronic unit 30. Specifically, the conductive arm 36 is a curved elongated flat plate. The two conductive arms 36 are electrically connected to the jaws 37 respectively, for electrically connecting to the conductive bars 23a and 23b of the power busbar 20. Furthermore, each conductive arm 36 includes a connecting section 38, which includes a plurality of spring arms 39 arranged in parallel, and the plurality of spring arms 39 can have an appropriate spacing H. Compared with a single elongated flat conductive arm 36, a conductive arm 36 composed of a plurality of spring arms 39 can tolerate greater elastic deformation in the direction of connection between the connector 35 and the electronic unit 30. In addition, the conductive arm 36 can be partially or entirely implemented with a plurality of spring arms 39 to replace the single elongated flat plate implementation.

Figure 6 is a schematic diagram of the internal components of the power bus bridging device 50 according to the first embodiment of this disclosure. Figure 7 is a perspective view of the cabinet power bridging structure according to the first embodiment of this disclosure. Figure 8 is a schematic diagram of the electrical connection of the cabinet power bridging structure according to the first embodiment of this disclosure. Referring to Figures 5 to 8, the power bus bridging device 50 is used to electrically connect multiple power buses 20, 20a of multiple cabinets 10, 10a. The power bus bridging device 50 includes a columnar housing 100, multiple power connectors (200, 200a), and multiple conductive bridges (300, 300a). In this embodiment, the power bus bridging device 50 includes a cylindrical housing 100, two power connectors (200, 200a), and two conductive bridges (300, 300a). The two power connectors (200, 200a) are respectively disposed at appropriate positions on the cylindrical housing 100, for example, in Figures 5 and 6, the two power connectors (200, 200a) are respectively disposed at two ends of the cylindrical housing 100. Each power connector (200, 200a) includes a connector (210, 210a), and the two connectors 210, 210a protrude and are exposed on the same side of the cylindrical housing 100. Each connector (210, 210a) includes a pair of clamps (211, 211a). Conductive bridges (300, 300a) are disposed within the cylindrical housing 100. Each conductive bridge (300, 300a) is connected at both ends to its corresponding power connector (200, 200a). Furthermore, each conductive bridge (300, 300a) is electrically connected to the respective jaws (211, 211a) of the power connector (200, 200a), for electrical connection to the conductive bars 23a and 23b of the power busbar 20. The cylindrical housing 100 can be a square column, cylinder, or other columnar body with a suitable geometry and appropriate rigidity to provide protection and insulation for the conductive bridges (300, 300a) and other components housed within it. Each conductive bridge 300 (300a) has a pair of conductive arms 310 (310a) located at both ends of the conductive bridge. Each conductive arm 310 (310a) is a curved elongated flat plate, and each conductive arm 310 (310a) is connected to a corresponding power connector (200, 200a). The structure of the conductive arm 36 shown in Figure 2 can also be applied to these two conductive arms 310 (310a).

[0030] Referring to Figures 1 and 2, each power bus 20, 20a in each cabinet 10 (10a) includes a housing 40 (40a). Referring to one of the power bus 20 shown in Figure 3, the housing 40 covers the bridging side 22 of the power bus 20. Referring to Figure 4, the housing 40 is provided with at least one opening 41, and the housing 40 includes a gate 42 corresponding to the opening 41. The gate 42 can be configured to expose or close the opening 41 by moving up and down, rotating laterally, or rotating vertically to prevent accidental contact by personnel. For example, the gate 42 can move up and down, selectively closing the opening 41 as shown in Figure 3 or exposing the opening 41 as shown in Figure 4.

[0031] Referring to Figure 7, in this embodiment, the two power distribution sides (11, 11a) on the two cabinets (10, 10a) are arranged side by side. Figure 9 is a cross-sectional view of the cabinet power bridging structure of the first embodiment disclosed herein. For ease of presentation, Figure 8 omits the outer shell of each cabinet 10 (10a) shown in Figure 9 and the cover 40 (40a) of each power bus (20 (20a)). The gate 42 can selectively open the opening 41 as shown in Figure 4. When the gate 42 is opened as shown, the opening 41 aligns with a portion of the bridging side 22 of the power bus 20. Therefore, the power connector 200 corresponding to Figure 1 can pass through the opening 41 and dock with the bridging side 22 of the power bus 20 as shown in Figures 7 to 9.

[0032] Referring to Figures 8 and 9, each power connector (200, 200a) of the power bus bridging device 50 is respectively mated to the conductive bars 23a and 23b of the power bus 20, 20a at the bridging sides (22, 22a) of the power bus 20, 20a. Figure 9 is a cross-sectional view of the cabinet power bridging structure of the first embodiment disclosed herein. Referring to Figure 9, the connector 210 of any power connector 200 on the power bus bridging device 50 can pass through the opening 41 and clamp the bridging side 22 of the power bus 20 with the jaws 211 of the connector 210. Specifically, each pair of jaws 211 (211a) clamps the bridging side 22 (22a) of the corresponding power bus 20 (20a).

[0033] Referring to Figures 8 and 9, when the electronic unit 30 (30a) is connected to the corresponding power bus 20 (20a) via the power connector 34 (34a), the connector 35 (35a) clamps the bus side 21 (21a) of the power bus 20 (20a) with the pair of jaws 37 (37a). The plurality of elastic arms 39 (39a) of the conductive arm 36 (36a) connected to the connector 35 (35a) can provide greater elastic deformation to allow for assembly buffer between the connector 35 (35a) and the electronic unit 30 (30a), thereby allowing for assembly tolerances during mating to avoid stress concentration, while the conductive arm 36 (36a) can also maintain the original structural strength.

[0034] Referring to Figure 10, in the second embodiment disclosed herein, the cabinet power bridging structure is applied to power bridging between three cabinets (10, 10a, 10b). This embodiment's cabinet power bridging structure includes three power buses (20, 20a, 20b) and two power bus bridging devices (50, 50a) respectively disposed on the three cabinets (10, 10a, 10b). The construction of each cabinet (10, 10a, 10b) is the same as that of the cabinet (10, 10a) described in the first embodiment, and the construction of each power bus bridging device (50, 50a) is also the same as that of the power bus bridging device 50 described in the first embodiment. Therefore, the construction of the cabinets (10, 10a, 10b) and the power bus bridging devices (50, 50a) will not be described again in this embodiment.

[0035] In this embodiment, three cabinets (10, 10a, 10b) are arranged side-by-side in a row, and their three power distribution sides (11, 11a, 11b) are also arranged side-by-side in a row.

Specifically, each power bus bridging device (50, 50a) connects to the corresponding power bus (20, 20a, 20b) on each cabinet 10 using a connection method similar to that described in the previous embodiment, with each power connector (200, 200a). This configuration enables power transmission between the three cabinets (10, 10a, 10b). Different combinations of electronic units 30 can be installed in each rack (10, 10a, 10b). For example, rack 10a can be configured to include electronic units 30a such as power supply unit 32a and battery backup unit 33a to provide power to other racks, while racks 10 and 10b can be configured to include units such as server units (31, 31b) that only consume power. By supplying power to racks 10 and 10b through rack 10a in the embodiment of FIG10, the space configuration of each rack is made more efficient.

[0036] Referring to Figures 11 and 12, in the third embodiment of this disclosure, the cabinet power bridging structure includes three cabinets (10, 10a, 10b) and a power bus bridging device 50b. The construction of each cabinet (10, 10a, 10b) is the same as that described in the preceding embodiments; therefore, the construction of the cabinets (10, 10a, 10b) will not be repeated in this embodiment.

[0037] Referring to Figure 12, in this embodiment, the power bus bridging device 50b includes a cylindrical housing 100b and three power connectors (200, 200a, 200b). The cylindrical housing 100 and each power connector (200, 200a, 200b) are constructed as in the previous embodiments. The difference between this embodiment and the previous embodiments lies in the positional arrangement of the power connectors (200, 200a, 200b) on the cylindrical housing 100b. In this embodiment, two of the three power connectors (200, 200b) are respectively disposed at the two ends of the cylindrical housing 100b, and the other power connector 200a is disposed in the middle section of the cylindrical housing 100. The three connectors (210, 210a, 210b) on the three power connectors (200, 200a, 200b) all protrude from the same side of the cylindrical housing 100.

A power bus bridging device 50b spans the three cabinets (10, 10a, 10b), and each power connector (200, 200a, 200b) of the power bus bridging device 50b is connected to each cabinet (10, 10a, 10b) in the same manner as in the aforementioned embodiment. This configuration enables power transmission between the three cabinets (10, 10a, 10b).

[0039] Referring to Figure 13, in the fourth embodiment of this disclosure, the cabinet power bridging structure is applied to two cabinets (10c, 10d). The cabinet power bridging structure includes multiple power buses (20c, 20d) disposed in each cabinet (10c, 10d) and a power bus bridging device 50c. The construction of each cabinet (10c, 10d) is the same as that of cabinets 10, 10a, and 10b described in the previous embodiments; therefore, the construction of cabinets (10c, 10d) will not be repeated in this embodiment. In this embodiment, the two power distribution sides (11c, 11d) of the two cabinets (10c, 10d) are arranged facing each other.

[0040] In this embodiment, the power bus bridging device 50c includes a cylindrical housing 100c and two power connectors (200c, 200d). The structure of the cylindrical housing 100c and each power connector (200c, 200d) is generally similar to the aforementioned embodiments. The main difference between this embodiment and the aforementioned embodiments lies in the positional arrangement of the plurality of power connectors (200c, 200d) on the cylindrical housing 100c. In this embodiment, the two power connectors (200c, 200d) are respectively disposed at two ends of the cylindrical housing 100c, and the two connectors (210c, 210d) protrude from the cylindrical housing 100c opposite to each other along the longitudinal direction of the cylindrical housing 100c. Each power connector (200c, 200d) of the power bus bridging device 50c is respectively connected to each power bus (20c, 20d) on each cabinet (10c, 10d). As in the previous embodiment, each power connector (200c, 200d) clamps its connector (210c, 210d) to the corresponding power bus (20c, 20d). This configuration enables power transmission between the two cabinets 10c and 10d.

[0041] In another embodiment, multiple power connectors of the power bus bridging device can be respectively disposed on adjacent sides of the columnar housing, so that the two cabinets can transmit power at a relative position of approximately 90 degrees.

[0042] The cabinet power bridging structure disclosed herein can easily connect multiple cabinets by means of a power bus bridging device, thereby enabling power transmission between these cabinets and allowing power to be supplied to one cabinet at a time while simultaneously supplying power to all other cabinets, thus facilitating equipment expansion.
