Figure 2 2 is a schematic exploded perspective view of a cabinet power bridging structure and a cabinet according to the first embodiment of the present disclosure.
[0052] See Figure 2 In this embodiment, the cabinet 10 includes a rectangular cabinet body, and the cabinet body can be installed with multiple electronic units 30. The present disclosure does not limit the form of the electronic unit 30. For example, the electronic units 30 shown in this embodiment include a server unit 31, a power supply unit 32 and a battery backup unit 33 (Backup Battery Unit, BBU). The server unit 31 can include components such as a microprocessor, a digital circuit, an analog circuit, a memory and a storage device.

The cabinet 10 includes a power bus 20 arranged on the power distribution side 11 of the cabinet body, as shown in FIG. Figure 1 The two ends of the power busbar 20 are respectively fixed to the upper end and the lower end of the cabinet.
[0053] See Figure 1 and Figure 2The cabinet power bridging structure includes a plurality of power buses (20, 20a) provided 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 the other cabinet 10a, thereby enabling power transmission and dispatching 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 body and is approximately perpendicular to the plane on which the cabinet 10 is placed. The power bus bridging device 50 is connected to the side of the two power buses (20, 20a) farther away from the cabinet, and the axial direction of the power bus bridging device 50 is approximately parallel to the plane on which the cabinet 10 is placed. In other embodiments, the power bus 20 , the cabinet 10 , the plane on which the cabinet 10 is placed, and the power bus bridging device 50 may also be set to other appropriate connection angles.
[0054] 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 during certain periods of time. For example, the power supply unit 32 may only charge its battery while not supplying power to the server unit 31, other power supply units, and / or the battery backup unit 33. The battery backup unit 33 may perform either power supply or power storage functions depending on the configuration.

The electronic units 30 are connected to the bus side 21 of the power bus 20. In this embodiment, the power bus 20 is arranged upright, and a plurality of electronic units 30 are set in the cabinet 10, for example, Figure 2 The plurality of electronic units of the embodiment includes a server unit 31 and two power supply units (32, 32a), the electronic units 30 are stacked and arranged in the cabinet body of the cabinet 10, and the side of the electronic units 30 facing the power bus 20 includes a power connector 34 for connecting to the power bus 20.

The two conductive arms 36 are electrically connected to the clamping jaws 37, respectively, for electrically connecting to the conductive bars 23a and 23b of the power bus 20. Furthermore, each conductive arm 36 includes a connecting section 38, which includes a plurality of elastic arms 39 arranged in parallel. The plurality of elastic arms 39 can have an appropriate spacing H. Compared to a single, long, flat conductive arm 36, a conductive arm 36 composed of multiple elastic arms 39 can tolerate greater elastic deformation in the direction connecting the connector 35 and the electronic unit 30. In addition, a conductive arm 36 can be partially or entirely implemented with multiple elastic arms 39, replacing the single, long, flat conductive arm.

[0063] See Figure 10In a second embodiment of the present disclosure, a cabinet power bridging structure is used for power bridging between three cabinets (10, 10a, 10b). The cabinet power bridging structure of this embodiment includes three power buses (20, 20a, 20b) and two power bus bridging devices (50, 50a) respectively arranged on the three cabinets (10, 10a, 10b). The structure of each cabinet (10, 10a, 10b) is the same as the cabinet (10, 10a) described in the first embodiment, and the structure of each power bus bridging device (50, 50a) is also the same as the power bus bridging device 50 described in the first embodiment.

[0066] See Figure 12In this embodiment, the power bus bridge device 50b includes a cylindrical housing 100b and three power connectors (200, 200a, 200b). The cylindrical housing 100 and the power connectors (200, 200a, 200b) are similar in structure to the aforementioned embodiments. This embodiment differs from the aforementioned embodiments in the positional arrangement of the plurality of power connectors (200, 200a, 200b) on the cylindrical housing 100b. In this embodiment, two of the three power connectors (200, 200b) are respectively arranged at two ends of the cylindrical housing 100b, and the other power connector 200a is arranged in the middle of the cylindrical housing 100. Furthermore, 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.

The structure of each cabinet (10c, 10d) is similar to the cabinets 10, 10a, and 10b described in the previous embodiments. Therefore, the structure of the cabinets (10c, 10d) will not be further described in this embodiment. In this embodiment, the two power distribution sides (11c, 11d) of the two cabinets (10c, 10d) are arranged facing each other.
[0069] In this embodiment, the power busbar bridging device 50c includes a cylindrical housing 100c and two power connectors (200c, 200d). The structures of the cylindrical housing 100c and the power connectors (200c, 200d) are generally similar to those of 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 arranged at two ends of the cylindrical housing 100c, and the two connectors (210c, 210d) protrude from the cylindrical housing 100c in opposite directions along the longitudinal direction of the cylindrical housing 100c. Each power connector (200c, 200d) of the power bus bridge device 50c is connected to each power bus (20c, 20d) on each cabinet (10c, 10d), respectively, just as each power connector (200c, 200d) clamps and connects to the corresponding power bus (20c, 20d) with its connector (210c, 210d) in the aforementioned embodiment. The aforementioned configuration enables power transmission between the two cabinets 10c, 10d.
[0070] In another embodiment, the plurality of power connectors of the power bus bridging device may 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.
