Connection structure of server power supply and mainboard

Abstract

The invention discloses a connection structure of a server power supply and a mainboard. The structure comprises power supplies, a mainboard, a flexible busbar and a power supply adapter plate, wherein the number of the power supplies is two, the two power supplies are placed in an overlapped mode, one side of each power supply is connected with a power supply adapter plate, a second conductive cylinder connected with the power supply is arranged on the power supply adapter plate, a first conductive cylinder is arranged on the mainboard, and the first conductive cylinder is connected with thesecond conductive cylinder through a flexible bar. The flexible printed circuit board adopts flexible printed circuit board connection; on the one hand, the position and structure of the mainboard donot need to be changed, cost is saved, and on the other hand, the flexible printed circuit board can be bent according to space and used more conveniently; through the improvement of the structural design, the original power supply tiling structure is changed into a superposition mode, so the horizontal space of the case is greatly saved, the saved space can provide a better heat dissipation effect for the case according to more heat dissipation fans, the upper space of the case is reasonably utilized, the space waste is avoided, and the reasonable utilization of the space is realized.

Description

technical field [0001] The invention relates to the technical field of connection between a mainboard and a power supply, in particular to a connection structure between a server power supply and a mainboard. Background technique [0002] With the rapid development of Internet technology and 4G network broadband, big data and network communication have become one of the hottest words in the IT field. One of the characteristics of big data is the large amount of data, which makes data storage and management more challenging. The demand for servers in all walks of life is getting higher and higher, and 2U servers are still the most in-demand server type. [0003] PSU (power supply unit power supply module) is essential in the server. It converts the external 220V AC into 12V DC and outputs it to the motherboard, and converts it into 12V, 5V, and 3.3V through the motherboard for CPU, memory, backplane, and external plug-in. The card and other power supplies ensure the normal o...

Problems solved by technology

[0004] Because the user computer room cannot be unified and the environment of the user computer room is different, in order to facilitate the maintenance of the server in the whole cabinet, the structural requirements for the server PSU are also different. The commonly used power supplies on the 2U server are 550W, 800W, 1300W and 1600W, and it is required to achieve 1+ 1 redundancy, so it needs to be able to support two power supplies. At present, the power supplies in the server are tiled, such as figure 1 As shown, when tiled, the two power supplies can be directly connected to the power connectors on the motherboard through the design of the motherboard and the chassis, but the tiled way will increase the horizontal space requirements inside the chassis, resulting in no extra space for installing fans
