Description
Technical field
The present invention relates to a kind of adapter, more particularly to a kind of M.2 interface adapter.
Background technology
At present, developing rapidly with medium, capacity and performance are all being lifted continuously and healthily, and major medium manufacturer all releases
High performance NVMe SSD.The interface of the general supports of NVMe SSD is M.2 interface.However, M.2 interface possesses more as one kind
High transmission performance, it is more compact, the new interface specification of MSATA is substituted, due to its compact volume specification, is usually fitted extensively
For ultra-thin fields such as mobile phone, tablet computer and ultra-thin notebooks, position often then is used to M.2 interface on equipment is used
It is stringent to put exception, fixes and is difficult to extend.Therefore, how it is more preferable and more easily extend M.2 interface become one it is important
Technical problem.
For the problems of in the prior art, there is provided a kind of M.2 interface adapter is of great significance.
The content of the invention
To solve the above problems, the present invention provides a kind of M.2 interface adapter.
To achieve the above object, M.2 interface adapter of the invention, including switching circuit board, the switching circuit board
Side is provided with golden finger, and M.2 interface is additionally provided with the switching circuit board, and the M.2 interface passes through built-up circuit and institute
Golden finger is stated mutually to be electrically connected；
Further, the built-up circuit is used to receive the signal of the golden finger transmission and converts the signals to
M.2 signal；
Further, the golden finger is made of multiple conductive contact blades, and the golden finger is used to be connected with PCIE slots；
Further, the PCIE slots are PCIE X16 slots；
Further, the M.2 interface can also be U.2 interface；
Further, two angles end of the side opposite with golden finger of the switching circuit board offers mounting hole.
A kind of M.2 interface adapter of the present invention, can realize PCIE slots and M.2 mutuallyying transfer between interface, can
With to provide more flexible configuration in hardware device, in the case where many PCIE slots are not required in user, using its groove position,
Realize to M.2 interface and the M.2 extension of interface equipment.
Brief description of the drawings
Fig. 1 is the structure diagram of M.2 interface adapter of the present invention；
Fig. 2 is the connection relationship diagram of M.2 interface adapter of the present invention.
Embodiment
In the following, it is further described with reference to attached drawing, structure and operation principle to the present invention etc..
As shown in Figure 1, Fig. 1 is the structure diagram of M.2 interface adapter of the present invention.Including switching circuit board 1, institute
The side for stating switching circuit board 1 is provided with golden finger 3, it is preferable that the golden finger 3 is described to be made of multiple conductive contact blades
Golden finger 3 is used to be connected with PCIE slots.In a preferred embodiment of the present invention, the golden finger 3 is used for and PCIE
X16 slots match connection, and normally, the length of the slot of the PCIE X16 is 71.65mm, therefore the length of the golden finger
Degree is also configured as 71.65mm.
M.2 interface 2 are additionally provided with the switching circuit board 1, the M.2 interface 2 passes through built-up circuit and the golden hand
Finger is mutually electrically connected.M.2 the quantity of the interface 2 can be multiple.M.2 the interface 2 is a kind of replacement interface new MSATA
Specification, is NGFF interfaces.The built-up circuit is used to receive the signal of the golden finger transmission and converts the signals to
M.2 signal.Normally, the M.2 protocol-compliant of interface and PCIE interfaces, therefore, the built-up circuit is without to receiving the gold
The transport protocol of the PCIE interfaces of finger transmission is changed, it is only necessary to which the signal for the PCIE interfaces for transmitting the golden finger turns
It is changed to M.2 signal.Under special circumstances, if the transport protocol of the interface of golden finger connection is assisted with transmission M.2
Discuss not compatible, the built-up circuit is also responsible for the protocol conversion of the interface signal in the lump transmitting the golden finger as M.2
Interface protocol.Normally, M.2 there are two kinds of transport protocols, Socket 2 and Socket 3, Socket2 support SATA and PCIE to lead to
Road, Socket 3 support PCIE channel.For different the uses M.2 equipment of interface, both transport protocols are supported,
It is only otherwise varied in transmission rate.
Further, the M.2 interface can also be that U.2 interface, the U.2 interface can be transferred mutually with M.2 interface,
For the M.2 interface of 32Gbps bandwidth, it is possible to achieve the performance undamaged switching between U.2 interface.U.2 the interface with
M.2 the interface equally supports PCIE channel, and is to be used for realization the interface supported NVMe specifications at present, described U.2 to connect
The theoretical bandwidth higher of mouth, and power consumption is lower.But either M.2 still U.2 interface, maximum short slab come interface at present
It is inadequate from the supporting dynamics in mainboard or hardware device.Because SATA is the mainstream configuration of current hardware and mainboard, if mainboard
M.2 or U.2 manufacturer is changed to, can expend substantial amounts of production cost and R＆D costs by SATA is some or all of.But due to
The fast development of NVMe SSD, adapts to the M.2 interface of NVMe specifications and U.2 the demand of interface also gradually steps up, moreover, right
For NVMe SSD, the space of extension is undoubtedly The more the better, opposite, for the frivolous manufacturer of constantly pursuit equipment
Speech, but in not short its extending space of compression.Therefore, no matter in the future major hardware or mainboard manufacturer either with or without to M.2 interface or U.2
Interface carries out increasing and matches somebody with somebody, and a kind of M.2 interface adapter proposed in technical scheme is respectively provided with great meaning.
In a kind of preferred embodiment of the present invention, two of the side opposite with golden finger 3 of the switching circuit board 1
Angle end offers mounting hole 4.The mounting hole 4 is used to be fixed on electronic equipment or mainboard, makes the M.2 interface adapter
It is fixed more to stablize, it is more firm using the plug of the M.2 equipment of interface 2 to ensure.
As shown in Fig. 2, Fig. 2 is the connection relationship diagram of M.2 interface adapter of the present invention, currently preferred
In embodiment, four M.2 interface 2 are shared, the M.2 interface 2 is disposed side by side on the switching circuit board 1, each institute
State M.2 interface 2 to be electrically connected by built-up circuit 5 and 3 phase of golden finger, the golden finger 3 is used to insert with PCIE X16
6 phase of groove is electrically connected, and the M.2 interface 2 is used for the equipment with using M.2 interface, i.e. NVMe SSD flash memories 7, is mutually electrically connected.
More than, it is only schematic description of the invention, it will be recognized by those skilled in the art that in the work without departing from the present invention
On the basis of making principle, a variety of improvement can be made to the present invention, this belongs to protection scope of the present invention.
