To realize above-mentioned purpose, the utility model adopts the following technical scheme:

A kind of extension of more expansion slot is multiplexed PCIE bus control system, including a mainboard, is connected to one of mainboard Adapter and two NIC for being connected to adapter, the adapter include a PCIE mainboard interface, a PEX core Piece, one for power supply 4P power supply interface, two for realizing drawer type extension the first PCIE expansion slot, one for taking Extension PCIE connecting component and a 2nd PCIE expansion slot for other subcards of extending user with other adapters, institute It states PEX chip and is electrically connected PCIE mainboard interface, the first PCIE expansion slot, extension PCIE connecting component and the 2nd PCIE expansion Slot is opened up, aforementioned mainboard has mainboard connecting component, and the mainboard connecting component connects PCIE mainboard interface, each the first PCIE Expansion slot connects a NIC.

As a preferred embodiment, the PCIE mainboard interface, the first PCIE expansion slot and the 2nd PCIE expansion slot are equal For PCIEx8 interface.

As a preferred embodiment, the PCIE mainboard interface is located at the left side of adapter, all first PCIE expansion slot Positioned at the front side of adapter, the extension PCIE connecting component is located at the right side of adapter, and the 2nd PCIE expansion slot is located at The rear side of adapter, the 4P power supply interface are located at the rear side of adapter.

As a preferred embodiment, the PCIE mainboard interface and extension PCIE connecting component are to be symmetrical set.

As a preferred embodiment, the extension PCIE connecting component and mainboard connecting component are golden finger interconnecting piece Part.

The utility model has clear advantage and beneficial effect compared with prior art, specifically: it is mainly logical It crosses PEX chip, complete the polymerization of uplink and downlink data and is fanned out to, realize the function of extension PCIE bus, master is greatly improved The compatibility of plate, so that performance is largely played；Especially, subcard can be extended and other adapters of arranging in pairs or groups, led to With property preferably and practicability it is stronger；

Followed by, by 4P power supply interface, it can be avoided the case where power supply limits, guarantee the power demands of each extension；

And the structure arrangement of each funtion part of adapter is ingenious rationally, so that adapter is compact-sized, occupies Space is small, meanwhile, conveniently install and use；In addition, pass through the extension of two the first PCIE expansion slot and other adapters, it is maximum real The function of existing 40 GBE interfaces or 40 SFP Interface Expandings.

In order to explain the structural features and functions of the invention more clearly, come with reference to the accompanying drawing with specific embodiment to its into Row is described in detail.

Specific embodiment

The utility model is further described with specific embodiment with reference to the accompanying drawing.

As depicted in figs. 1 and 2, the extension multiplexing PCIE bus control system of a kind of more expansion slot, including a mainboard 10, It is connected to an adapter 20 of mainboard 10 and is connected to two NIC30 of adapter 20, the adapter 20 includes One PCIE mainboard interface 22, the one PEX chips 21, two of 4P power supply interface 23, one for power supply are for realizing drawer The first PCIE expansion slot 24, one of formula extension are for the extension PCIE connecting component 25 for other adapters 20 of arranging in pairs or groups and one The 2nd PCIE expansion slot 26 for other subcards of extending user, in which:

The PEX chip 21 is electrically connected PCIE mainboard interface 22, the first PCIE expansion slot 24, extension PCIE interconnecting piece Part 25 and the 2nd PCIE expansion slot 26, aforementioned mainboard 10 have mainboard connecting component, and the mainboard connecting component connects PCIE Mainboard interface 22, each the first PCIE expansion slot 24 connect a NIC30；Preferably, two NIC 30 pass through respective PCIEx8 golden finger is connected to corresponding first PCIE expansion slot 24.

In the present embodiment, the PCIE mainboard interface 22 is located at the left side of adapter 20, all first PCIE expansion slot 24 are located at the front side of adapter 20, and the extension PCIE connecting component 25 is located at the right side of adapter 20, and the PCIE mainboard connects Mouth 22 and extension PCIE connecting component 25 are to be symmetrical set.After the 2nd PCIE expansion slot 26 is located at adapter 20 Side, the 4P power supply interface 23 are located at the rear side of adapter 20, since it is considered that the confession that the power supply of specification is limited and respectively extended Electricity demanding, so increasing 4P power supply interface 23,4P power supply interface 23 is electrically connected in PEX chip 21, the first PCIE extension Slot 24, extension PCIE connecting component 25 and the 2nd PCIE expansion slot 26.

Preferably, the PCIE mainboard interface 22, the first PCIE expansion slot 24 and the 2nd PCIE expansion slot 26 are PCIEx8 interface；Each PCIEx8 interface is corresponding with multiple GBE interfaces or SFP interface, and maximum realizes 40 GBE interfaces or 40 SFP interface.

The extension PCIE connecting component 25 and mainboard connecting component are golden finger connecting component.Golden finger is by numerous golden yellow The conductive contact blade of color forms, because of its surface gold-plating and conductive contact blade arrangement such as finger-shaped, so being known as " golden finger ".Golden finger One layer of gold is covered with by special process again actually in copper-clad plate, because the inoxidizability of gold is extremely strong, and conductibility It is very strong.The connection reliability of adapter 20 Yu other adapters can be improved using this kind of connecting component.In the present embodiment, Expansion slot on his adapter is up to three, to sum up two the first PCIE expansion slot 24, and the utility model can achieve most 5 A expansion slot, each expansion slot are corresponding with 8 GBE interfaces or 8 SFP interfaces, thus maximum may be implemented 40 GBE interfaces or The function of 40 SFP Interface Expandings.

1 PCIEx8 signal is supplied to PEX chip 21 by the mainboard 10, and PEX chip 21 converts 1 PCIEx8 signal For 4 PCIEx8 signals, 2 PCIEx8 signals in 4 PCIEx8 signals are exported to two the first PCIE expansion slot 24, each First PCIE expansion slot 24 has 1 PCIEx8 signal or 2 PCIE x4 signals；In view of the extension of compatible different vendor Module and subcard, PCIE signal that the PEX chip 21 is fanned out to while supporting polarity reversion, lane reversion to realize compatibility.

The utility model designing points are, mainly pass through PEX chip, complete the polymerizations of uplink and downlink data with It is fanned out to, realizes the extension function of PCIE bus, the compatibility of mainboard is greatly improved, so that performance is largely sent out It waves；Especially, subcard can be extended and other adapters of arranging in pairs or groups, versatility is preferably and practicability is stronger；

The above is only the utility model preferred embodiment, not appoints to the technical scope of the utility model What is limited, therefore any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent variations With modification, it is still within the scope of the technical solutions of the present invention.
