1. Technical Field
The present disclosure relates to power supply devices and power supply systems, and particularly to a power supply device and a power supply systems for a server rack.
2. Description of Related Art
Blade and rack-mounted servers are popular for data center servers. In order to achieve high performance, many rack-mounted servers are clustered in an enclosure. A server rack assembly may include a server rack and a plurality of servers received in the server rack. Each of the plurality of servers is connected to a power supply, and the power supply may include a power transforming module and a power-setting module. Thus, a plurality of power supplies, including a plurality of power transforming modules and a plurality of power-setting modules, are received in the server rack. When the plurality of servers needs maintenance, it can be confusing to service because of the plurality of power transforming modules and a plurality of power-setting modules. Therefore, an improved power supply device and an improved power supply system for a server rack with the power supply device is desirable.

Each of the top portion and the bottom portion includes a first assistant bus-bar 31, a second assistant bus-bar 33, a plurality of connectors 35, a plurality of second insulating layers 36, and a positioning piece 37. The first assistant bus-bar 31 defines a plurality of first positioning holes 312 and a plurality of first receiving holes 315. An end of the first assistant bus-bar 31 defines a first cutout 311 and two first installation holes 316. The second assistant bus-bar 33 defines a plurality of second positioning holes 332 corresponding to the plurality of first positioning holes 312, and a plurality of second receiving holes 335 corresponding to the plurality of first receiving holes 315. An end of the second assistant bus-bar 33 defines a second cutout 331 and two second installation holes 336. The second cutout 331 corresponds to the first cutout 311. Each of the two second installation holes 336 corresponds to the first installation holes 316. A second insulating cushion (not shown) is secured in an inner surface of each first positioning hole 312 and each second positioning hole 332. Each connector 35 includes a first pin 351 and a second pin 353. The first pin 351 can be inserted into the first receiving hole 315, and the second pin 353 can be inserted into the second receiving hole 335. The plurality of second insulating layers 36 are adapted to adhere to each side of the first assistant bus-bar 31 and the second assistant bus-bar 33. Each of the plurality of second insulating layers 36 defines a plurality of positioning holes 361. The positioning piece 37 defines a plurality of first locking holes 371 and a plurality of second locking holes 373.
In assembly of the assistant bus-bar module 30, each of the plurality of second insulating layers 36 adheres to each side surface of each of the first assistant bus-bar 31 and the second assistant bus-bar 33. The first cutout 311, the second cutout 331, the first installation hole 316 and the second installation hole 336 are exposed out of the plurality of second insulating layers 36. The first assistant bus-bar 31 is moved to be adjacent to the second assistant bus-bar 33, and the first positioning hole 312 is aligned with the second positioning hole 332 and the positioning hole 361. Another locking member is inserted into the first positioning hole 312, the second positioning hole 332, and the positioning hole 361, to secure the first assistant bus-bar 31 to the second assistant bus-bar 33.
