Embodiment
Below in conjunction with attached drawing, by embodiment, the invention will be further described.
The RACK server node electric power-feeding structures of the present invention, are for high-power server section used in client feedback
Point occurs power-off problems and proposes once in a while, i.e. the present invention is mainly solved in RACK server multinode electric power systems,
The conducting problem of super-large current in single node power-supply system.
As shown in Figure 1, single node power-supply system refers to：From the 12V electric currents of RACK server power supplies pond output, by copper bar
It is conducted to the power supply backplane of each node, then to this section of path of server master board.Wherein, the power supply backplane of each node is logical
Power-feed connector is crossed with copper bar to be connected.Therefore, the electric current from copper bar to power supply backplane on this section of power supply link can be very big.And
And due to the limitation of structure, in height can structure constraint using two groups of traditional node power-feed connector carrying high currents.
During installation, AC power supplies output is screwed on copper bar 1 by cable, and one group of power-feed connector 2 has two, and one
Another 1 anode of connecting copper bar of a 1 cathode of connecting copper bar, the cathode and anode of power-feed connector 2 are screwed in respectively
On node server mainboard PCB, power for server master board.
By research staff to being found after the investigation of existing high-power server node power down, existing server node power down
Impedance caused by being primarily due to the oxidation of copper bar and power-feed connector contact surface is bigger than normal and triggers, i.e. in long-time high current
Under operating mode, the situation of oxidizing blackening occurs in the contact surface of nickel plating copper bar and silver-plated connector.
The problem of being found based on investigation, to improve the problem of oxidation under high current operating mode, the present invention compared for respectively
The impedance magnitude and resistance to oxidation situation of metalloid conductor contact surface, wherein, the minimum 1.6m Ω of silver-colored contact impedance, but resistance to oxidation
Stability is not as gold, therefore final choice is gold-plated in the position that copper bar 1 is contacted with power-feed connector 2, meanwhile, power-feed connector 2
It is internal also gold-plated, thereby ensure that both contact surfaces will not chemically react, avoid aoxidizing, reduce contact impedance, reduce and pass
Temperature rise caused by high current is led, avoids the occurrence of server node power-off problems, ensure that product electrical stability.
