[0064] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0065] Refer to the following Figures 1 to 12A power distribution device 1 according to an embodiment of the present application is described.

[0066] Figure 1 A schematic diagram showing the structure of a power distribution device 1 according to an embodiment of the present application is shown. Figure 2 FIG. 1 is a schematic diagram of an exploded structure of a power distribution device 1 according to an embodiment of the present application. Figure 1 and Figure 2 As shown, the power distribution device 1 includes a housing 10, a busbar 20 and a wiring module 40. Specifically, a housing 10 defines an accommodation cavity inside. The busbar 20 is disposed in the accommodation cavity, and the busbar 20 is electrically connected to the power supply cable of the power distribution device. The wiring module 40 is disposed in the accommodation cavity, and the wiring module 40 is electrically connected to the busbar 20 through an internal cable, and is electrically connected to the power-consuming device through an external cable.

[0067] In the embodiment of the present application, the power distribution device 1 is used to provide power to the power-consuming devices in the data center, and can also be used to supply power to the switch or temporary load. The switch is used to provide network services to the power-consuming devices such as computing devices, and the temporary load can be any other device such as electronic products and lighting equipment.

[0068] In the embodiment of the present application, the number of the busbar copper bar 20 may be one or more. Figure 3 A schematic diagram showing the structure of multiple busbars 20 of the power distribution device 1 according to an embodiment of the present application is shown. Figure 3 As shown, in some optional examples of the present application, the number of the busbar copper bars 20 can be multiple, and the multiple busbar copper bars 20 are arranged at intervals in the first direction.

[0069] For example, the busbar copper bar 20 may be made of electrolytic copper with a purity of 99.9%. The size of the busbar copper bar 20 may be set accordingly according to the sum of the current carrying capacity of all the wiring units 41 included in the wiring module 40. The larger the sum of the current carrying capacity, the larger the size of the busbar copper bar 20. Those skilled in the art may flexibly set the size according to actual needs, and the embodiment of the present application does not specifically limit this.

[0070] In the embodiment of the present application, the wiring module 40 and the busbar copper bar 20 are arranged in the accommodating cavity at intervals, and the wiring module 40 may include a plurality of wiring units 41, each wiring unit 41 has a first wiring terminal and a second wiring terminal, the first wiring terminal is used to be electrically connected to the busbar copper bar 20 through an internal cable, and the second wiring terminal is used to be electrically connected to an electrical device through an external cable. In this way, the electrical connection between the busbar copper bar 20 and the electrical device is achieved, so as to supply power to the electrical device.

[0071] According to the power distribution device 1 of the embodiment of the present application, by adopting the busbar copper busbar 20 as the busbar, on the one hand, it is beneficial to reduce the overall temperature rise of the power distribution device 1 and improve the power supply stability; on the other hand, it is beneficial to extend the working life of the power distribution device 1, and the material of the busbar copper busbar 20 can be reused, thereby reducing the depreciation cost.

[0072] In one embodiment, there are multiple busbar copper bars 20 , and at least two of the multiple busbar copper bars 20 are spaced apart in the first direction.

[0073] It should be noted that the first direction may be any direction, for example, it may be a vertical direction or a horizontal direction after the power distribution device 1 is installed. That is, the plurality of busbar copper bars 20 may be spaced apart from each other in the vertical direction or in the horizontal direction.

[0074] By spacing the multiple busbar copper bars 20 in the first direction, it is possible to ensure that there is sufficient electrical clearance between the multiple busbar copper bars 20, so that when wiring the multiple busbar copper bars 20 and the wiring module 40, sufficient wiring space can be reserved for multiple internal cables. On the one hand, the convenience of wiring is improved, and on the other hand, the probability of the internal cables contacting other busbar copper bars 20 can be reduced, thereby improving the working reliability of the power distribution device 1.

[0075] Figure 4 A schematic diagram showing the structure of multiple busbars 20 of the power distribution device 1 according to an embodiment of the present application is shown. Figure 4 As shown, in one embodiment, a plurality of busbar copper bars 20 are spaced apart in a second direction, and the second direction is perpendicular to the first direction.

[0076] In the embodiment of the present application, the first direction may be any direction, and the second direction may be another direction perpendicular to the first direction.

[0077] In some examples, such as Figure 3 and Figure 4 As shown, the first direction may be a horizontal direction, specifically a length direction or a width direction of the power distribution device 1; the second direction may be a vertical direction, specifically a height direction of the power distribution device 1. The plurality of busbar copper bars 20 are arranged at intervals in the length direction or the width direction of the power distribution device 1, and are arranged at intervals in the height direction of the power distribution device 1.

[0078] More specifically, the structure of the busbar copper bar 20 can be a flat plate, and the plane where each busbar copper bar 20 is located can be perpendicular to the second direction. For example, the second direction can be a vertical direction, and the planes where the multiple busbar copper bars 20 are located can be perpendicular to the vertical direction, that is, the planes where the multiple busbar copper bars 20 are located are parallel to the horizontal plane.

[0079] In one embodiment, the plurality of busbar copper bars 20 may include one or all of a first phase busbar 21 , a second phase busbar 22 , and a third phase busbar 23 , as well as a neutral busbar 24 and a ground busbar 25 .

[0080] In some examples, the plurality of busbars 20 include a first phase busbar 21, a second phase busbar 22, a third phase busbar 23, a neutral busbar 24, and a ground busbar 25. The power distribution device 1 of the embodiment of the present application can adopt a three-phase five-wire AC power mode. Specifically, among the plurality of busbars 20, three busbars 20 can be electrically connected to the three-phase power lines (L1, L2, L3) to form a first phase busbar 21, a second phase busbar 22, and a third phase busbar 23, one busbar 20 can be electrically connected to the neutral line (N) to form a neutral busbar 24, and another busbar 20 can be electrically connected to the ground line (P) to form a ground busbar 25. In this way, the three-phase power supply of the power distribution device 1 can be achieved.

[0081] In addition, in some other examples, the power distribution device 1 can also be used for single-phase power supply. For example, among the multiple busbars 20, any one of the first phase busbar 21, the second phase busbar 22 and the third phase busbar 23 and the neutral line and the ground line can form a single-phase power supply.

[0082] In one embodiment, there are multiple busbar copper bars 20, each busbar copper bar 20 is provided with at least one first wiring hole, and the wiring module 40 includes at least one wiring unit 41; the first wiring terminal of each wiring unit 41 is electrically connected to one end of a plurality of internal cables through a fastener, and the other ends of the plurality of internal cables are respectively electrically connected to at least part of the busbar copper bars 20 through fasteners passing through the first wiring holes.

[0083] Optionally, the multiple busbar copper bars 20 include a neutral busbar 24 and a grounding busbar 25, and also include one or all of the first phase busbar 21, the second phase busbar 22, and the third phase busbar 23; the first wiring terminal of each wiring unit 41 is electrically connected to one end of a plurality of internal cables through a fastener, and the other ends of the plurality of internal cables are respectively electrically connected to the first wiring holes of the first phase busbar 21, the second phase busbar 22, and the third phase busbar 23, the neutral busbar 24, and the grounding busbar 25 through fasteners.

[0084] Exemplarily, the plurality of wiring units 41 include a first wiring unit and a second wiring unit, the input end of the first wiring unit being electrically connected to the first phase bus 21, any one of the second phase bus 22 and the third phase bus 23, the neutral bus 24 and the ground bus 25, respectively, and the second wiring unit being electrically connected to the first phase bus 21, the second phase bus 22, the third phase bus 23, the neutral bus 24 and the ground bus 25, respectively.

[0085] In addition, one end of the internal cable and the first end of the wiring unit 41 may be electrically connected by plugging or snapping, which is not specifically limited in the present application.

[0086] Optionally, the second wiring terminal of each wiring unit 41 is electrically connected to one end of an external cable via a fastener, and the other end of the external cable is electrically connected to an electrical device.

[0087] Exemplarily, the fastener may be a metal screw, one end of the external cable is electrically connected to the second terminal via the metal screw, and the other end of the external cable extends from the housing 10 and is electrically connected to the electrical device.

[0088] Optionally, the housing 10 is further provided with at least one wire outlet through hole connecting the accommodating cavity with the outside, and the other end of the external cable extends to the outside of the accommodating cavity through the corresponding wire outlet through hole.

[0089] Exemplarily, the plurality of wiring units 41 are arranged side by side in the third direction. In the embodiment of the present application, the third direction may be a direction perpendicular to the first direction and the second direction, respectively, and specifically may be a length direction of the power distribution device 1. The plurality of outlet through holes are arranged in a one-to-one correspondence with the plurality of wiring units 41, so that the external cables connected to the second wiring terminals of the wiring units 41 can extend to the outside of the housing 10 through the corresponding outlet through holes.

[0090] In some optional examples of the present application, the other ends of multiple external cables can be extended to the outside of the accommodating cavity through a common outlet hole. This arrangement can reduce the number of outlet holes on the housing 10 and reduce the difficulty of processing the housing 10.

[0091] Alternatively, if Figure 3 As shown, the ratio of the distance between two adjacent busbar copper bars 20 in the first direction to the size of the busbar copper bar 20 in the first direction is 1 to 2.

[0092] In an embodiment of the present application, the first direction can be the width direction of the power distribution device 1 (i.e., the front-to-back direction in the figure), the width direction of the busbar copper bus 20 is arranged parallel to the width direction of the power distribution device 1, and the dimension of the busbar copper bus 20 in the first direction can be understood as the width dimension of the busbar copper bus 20.

[0093] Exemplarily, the ratio of the spacing between two adjacent busbar copper bars 20 in the first direction to the width of the busbar copper bar 20 may be 1 to 2. Preferably, the ratio of the spacing between two adjacent busbar copper bars 20 in the first direction to the width of the busbar copper bar 20 may be 1.5.

[0094] In some specific examples, the width of the busbar copper bar 20 may be 30 mm, and the distance between two adjacent busbar copper bars 20 in the first direction may be 45 mm.

[0095] It should be noted that, when the spacing between two adjacent busbar copper bars 20 in the first direction is too large, for example, when the ratio of the size of the busbar copper bar 20 in the first direction is greater than 2, it will cause multiple busbar copper bars 20 to occupy too much space in the first direction, thereby causing the width of the power distribution device 1 to be too large and occupy too much installation space; when the spacing between two adjacent busbar copper bars 20 in the first direction is too small, for example, when the ratio of the size of the busbar copper bar 20 in the first direction is less than 1, it will cause the wiring space between the two adjacent busbar copper bars 20 to be too small, thereby causing inconvenience to the wiring between the busbar copper bar 20 and the wiring module 40.

[0096] Therefore, by setting the ratio of the spacing between two adjacent busbar copper bars 20 in the first direction to the size of the busbar copper bar 20 in the first direction to 1 to 2, it is beneficial to reduce the external dimensions of the power distribution device 1 and thus reduce the occupied installation space, and it can also bring convenience to the wiring between the busbar copper bar 20 and the wiring module 40.

[0097] Optionally, the ratio of the distance between two adjacent busbar copper bars 20 in the second direction to the size of the busbar copper bar 20 in the second direction is 3 to 7.

[0098] In an embodiment of the present application, the second direction can be the height direction of the power distribution device 1 (i.e., the up and down direction in the figure), the thickness direction of the busbar copper bar 20 is arranged parallel to the height direction of the power distribution device 1, and the size of the busbar copper bar 20 in the second direction can be the thickness size of the busbar copper bar 20.

[0099] Exemplarily, the ratio of the distance between two adjacent busbar copper bars 20 in the second direction to the height of the busbar copper bars 20 may be 3 to 7. Preferably, the ratio of the distance between two adjacent busbar copper bars 20 in the second direction to the height of the busbar copper bars 20 may be 5.

[0100] In some specific examples, the thickness of the busbar copper bar 20 may be 5 mm, and the distance between two adjacent busbar copper bars 20 in the second direction may be 25 mm.

[0101] It should be noted that, when the distance between two adjacent busbar copper bars 20 in the second direction is too large, for example, when the ratio of the size of the busbar copper bar 20 in the second direction is greater than 7, multiple busbar copper bars 20 will occupy too much space in the second direction, thereby causing the height dimension of the power distribution device 1 to be too large and occupy too much installation space; when the distance between two adjacent busbar copper bars 20 in the second direction is too small, for example, when the ratio of the size of the busbar copper bar 20 in the second direction is less than 3, the wiring space between the two adjacent busbar copper bars 20 will be too small, thereby causing inconvenience to the wiring between the busbar copper bar 20 and the wiring module 40.

[0102] Therefore, by setting the ratio of the spacing between two adjacent busbar copper bars 20 in the second direction to the size of the busbar copper bar 20 in the second direction to 3 to 7, it is beneficial to reduce the external dimensions of the power distribution device 1 and thus reduce the occupied installation space, and it can also bring convenience to the wiring between the busbar copper bar 20 and the wiring module 40.

[0103] In one embodiment, the busbar copper bar 20 is further provided with a second wiring hole for electrically connecting to a distribution cable of a power distribution device through a fastener.

[0104] For example, the second wiring hole can be arranged adjacent to the edge of the busbar copper bar 20 to reduce the length of the distribution cable extending into the accommodating cavity and improve the convenience of wiring. The fastener can be a metal part with conductive properties, such as a metal screw.
