For the traditional data center computer room, in order to avoid the huge investment in rebuilding the data center, and to meet the ever-increasing demand for information services. There is also an increasing need for high-density servers. The main reason is that high-density servers can make full use of the space in the computer room. By deploying high-density servers in the computer room, the capacity of data services can be expanded under the conditions of the existing computer room.

In high-density server applications, generally a single server node needs to support hot-swappable operations, and guide columns for structural positioning are usually installed on the server node. With the increase of user business volume, the load current on the mainboard side is getting larger and larger, causing the power supply port on the mainboard side to be too large and occupying too much space on the mainboard PCB. Heat dissipation in the box. At the same time, the structural space of this density server is limited, and the size of the traditional powerblade connector is relatively large. When conducting large currents and a large number of signals, the powerblade connector is often limited by the structure of the chassis.

In order to save limited space, improve node heat dissipation, and solve the problem of limited chassis structure. This paper proposes a new miniaturized connection device for power supply and signal sharing.
