Specific embodiment

It should be appreciated that specific embodiment described herein is only used to explain the utility model, it is not used to limit this Utility model.

Fig. 1 is please referred to, Fig. 1 is the structural representation of expansion card preferred embodiment of the utility model based on SFF-8654 interface Figure.

As shown in Figure 1, the expansion card based on SFF-8654 interface that the present embodiment proposes includes veneer 10, it is arranged in described Four SFF-8654 interfaces for the connection of external world's SFF-8654 connector on veneer 10, and it is arranged in the veneer 10 20 (the PCIE X16 of PCIE X16 slot for being used to plug PCIE device card that is upper, being gone out by four SFF-8654 Interface Expandings SLOT)。

Wherein, four SFF-8654 interfaces are connect by corresponding four golden finger interfaces 40 with external world SFF-8654 Device connection.

For the ease of installing and plugging PCIE device card, in the present embodiment, four SFF-8654 interfaces and described PCIE X16 slot 20 is respectively arranged in the opposite both ends of the veneer 10.

In the present embodiment, the PCIE device card supports X1, X2, X4, X8, X16 bandwidth, the size of the PCIE device card Can be following three kinds:

1, overall height Full-size card: 111.15mm*312.00mm (high * long)；

2, the long card of overall height half: 111.15mm*167.65mm (high * long)；

3, half high half long card: 68.90mm*167.65mm (high * long).

Further, it in the present embodiment, is there also is provided on the veneer 10 for the PCIE X16 slot 20 power supply Power interface 30.

Wherein, the power interface 30 is connect by power cable with extraneous power supply.The power interface 30 uses power supply 6pin connector, pin spacing are 4.2mm.

In addition, there also is provided the EERPOM chip for storing 10 information of veneer, institute on the veneer 10 in the present embodiment 10 information of veneer is stated including at least one or more of veneer functional information, veneer model, veneer sequence number.

The expansion card based on SFF-8654 interface that the present embodiment proposes is done below with reference to Fig. 1 to Fig. 6 further detailed It is thin to illustrate:

One, the design distribution of power supply

Because standard PCIE X16 slot 20 needs 3 groups of power supplys :+12V ,+3.3V and+3.3Vaux, uses and connect in the present embodiment Enter power cable and realize to the mode of power interface 30 power supply of+12V He+3.3Vaux, and+3.3V then+the 12V by inputting It is supplied by DC/DC conversion circuit；Wherein power interface 30 uses the power supply 6pin connector of standard, and pin spacing is 4.2mm, specific implementation block diagram are as shown in Figure 2.
