Among them, an anti-pull-off buckle is provided at the end of the plug-in part. The cavity is close to the side of the rear window of the cabinet, and evenly arranged holes are provided on the side of the first insulating shell 2 and the second insulating shell 4 close to the front window. The plug-in part of the second insulating shell 4 can slide up and down in the cavity in the first insulating shell 2.
[0031] Specifically, the whole cabinet server includes a cabinet shell and a server node, the power module is arranged in the server node, the cabinet shell includes a first side surface, a second side surface, a top surface, a bottom surface and a back surface, and the front side opening surface is opposite to the back surface; the power supply copper bar includes a power copper bar and a ground copper bar, the power module is connected to the power copper bar and the ground copper bar respectively, and the power supply module is connected to the power copper bar and the ground copper bar respectively; the power copper bar and the ground copper bar are arranged in an area close to the back of the cabinet shell, and the power module and the power supply module are arranged in an area close to the front side opening surface of the cabinet shell; the number of the power copper bar and the ground copper bar are both several; the number of server nodes is equal to the number of power modules, both of which are several. By increasing the number of copper bars and adding horizontal copper bars, the voltage drop and loss caused by the copper bars are reduced, and power supply from different positions of the entire cabinet is guaranteed.
[0032] In addition, in order to realize the retractability of the busbar 5, the length of the busbar 5 can be increased by splicing. The multi-section copper bar includes a first copper bar 1 and a second copper bar 3, the first copper bar 1 is installed in the first insulating shell 2, and the second copper bar 3 is installed in the second insulating shell 4; one end of the first insulating shell 2 is provided with a mounting base, and the mounting base is installed on the cabinet by bolts; one side of the first insulating shell 2 is provided with a plurality of evenly arranged plug holes; one end of the second insulating shell 4 is provided with a gold finger, the gold finger is connected to the second copper bar 3, and the size of the gold finger matches the plug hole.

The left and right positions are adapted to the 19-inch node and 21-inch node positions at the same time.
[0034] A parallel power copper busbar and a grounding copper busbar are installed in the insulating housing, so there is no need to set up a grounding wire for the power module. A plurality of regularly arranged blind plug sockets are provided on the insulating housing.
[0035] The specific installation method includes: the busbar 5 is fixed on the crossbeam bracket of the rear window, and fixing holes are reserved at the left, middle and right positions.

The busbar 5 adopts a narrow upper and wide lower method, with a thickness of 3mm at the top. Four M6 screws are required to fix the busbar 5 and Powerself (center distance spacing 14mm), and the screw hole fixing method is fixed. The busbar 5 and PowerClip are connected with locking screws, and the connection distance is set to 18mm. The entire cabinet is powered by 54V, the PowerClip is connected to the busbar 5, the connector end is connected to the PDB board, and the cable connection is used in the middle. One PowerClip connects two power connectors, which are used to connect two PDB boards when high power is required.
[0036] The cabinet supports busbar 5 modules that can be removed and installed separately. Busbar 5 runs through the entire cabinet and covers a height of 1U-47U space. It can be adapted to 19-inch and 21-inch server nodes by adjusting the installation position, increasing the position of the power supply and reducing losses. The server node power supply module is connected to busbar 5 on the cabinet side by blind plugging, and the current of busbar 5 is not less than 750A. Busbar 5 can be installed in the left, middle, and right positions. It is fixed on the right side of the rear view of the cabinet by default.
