[0033] The output terminal 3 includes an output positive terminal 31, an output negative terminal 32, and an output neutral terminal 33. These terminals are used to connect to an uninterruptible power supply device or other loads.
[0034] Positive connection: The input positive terminal 21 is electrically connected to the output positive terminal 31 through a wire or busbar to ensure that the positive pole of the power supply can supply power to the load.
[0035] Negative connection: The input negative terminal 22 is also electrically connected to the output negative terminal 32 through a wire or busbar to form the negative pole circuit of the power supply.
[0036] The neutral terminal is connected. The input neutral terminal 23 is electrically connected to the output neutral terminal 33 to provide a grounding or return path for the system.
[0037] In this embodiment, the positive terminal, negative terminal, and neutral terminal of the battery pack are respectively connected to the input terminals 2 of the uninterruptible power supply busbar box 100. Inside the uninterruptible power supply busbar box 100, the input terminals 2 are then electrically connected to the output terminals 3 by wiring.

The anti-fooling design of placing the input neutral terminal 23 between the input positive terminal 21 and the input negative terminal 22, and placing the output neutral terminal 33 between the output positive terminal 31 and the output negative terminal 32 can effectively reduce the possibility of inserting the cable incorrectly.
[0040] Please refer to Figure 2 and Figure 3 as well as Figure 4 In an embodiment of the present utility model, the housing 1 has a side shell 11, and the input terminals 2 and the output terminals 3 are spaced apart and installed on the same side shell 11.

[0054] In this embodiment, the current enters the interior of the uninterruptible power supply bus bar box 100 through the input positive terminal 21, and the current then flows through the fuse 41 along the cable. After passing through the fuse 41, the current reaches the bus bar 42. The bus bar 42 electrically connects the output terminal of the fuse 41 to the output terminal 3. The current flows through the bus bar 42 to the output terminal 3, and these terminals deliver the current to the uninterruptible power supply device.

Each group of fuses 41 is converged by a bus bar 42, and finally three cables are led out from the bus bar 42 to their respective corresponding output terminals 3.
[0057] Please refer to Figure 2 and Figure 5 as well as Figure 6 , in an embodiment of the present utility model, the uninterruptible power supply bus bar box 100 further includes cable ties 5. The cable ties 5 are provided on the inner side of the housing 1 on the side where the insurance device 4 is located. The cable ties 5 are protrusions having a second through hole 5a.
[0058] In this embodiment, the cable tie passes through the second through hole 5a to tie up the cable, thereby fixing the cable. This can reduce the risk of the cable moving or accidentally contacting the live components, thus improving the safety of the entire system. The cable tie 5 can protect the cable from damage caused by excessive bending or pulling, and extend the service life of the cable.
[0059] Please refer to Figure 1 and Figure 2 as well as Figure 4 , in an embodiment of the present utility model, the uninterruptible power supply busbar box 100 further includes a first heat dissipation hole 1a and a second heat dissipation hole 1b. The first heat dissipation hole 1a and the second heat dissipation hole 1b are respectively provided on two opposite sides of the housing 1; the first heat dissipation hole 1a is provided between the input terminal 2 and the output terminal 3, and the first heat dissipation hole 1a, the second heat dissipation hole 1b and the fuse device 4 are arranged on the same straight line.
[0060] The first heat dissipation hole 1a, the second heat dissipation hole 1b and the fuse device 4 are located on the same straight line. This linear layout helps to optimize the air flow and improve the heat dissipation efficiency. Good heat dissipation can extend the service life of the internal components of the uninterruptible power supply busbar box 100, and improve the reliability and stability of the entire uninterruptible power supply system. The design of the heat dissipation holes not only has functionality, but also can be coordinated with the overall appearance design of the uninterruptible power supply busbar box 100 to maintain aesthetics.
[0061] Please refer to Figure 1 and Figure 2 as well as Figure 4 , the present utility model also proposes an uninterruptible power supply system. This uninterruptible power supply system includes the uninterruptible power supply busbar box 100, a power module and an uninterruptible power supply device.
