The technical issues of.
How the technical solution of the application and the technical solution of the application are solved with specifically embodiment below above-mentioned
Technical problem is described in detail.These specific embodiments can be combined with each other below, for the same or similar concept
Or process may repeat no more in certain embodiments.Below in conjunction with attached drawing, embodiments herein is described.
Fig. 3 is the flow diagram of the detection method embodiment one of the slotting steady state of plug-in card provided by the embodiments of the present application.
Fig. 4 is the attachment structure schematic diagram one of veneer provided by the present application and plug-in card.The present embodiment is related to being to pass through veneer and plug-in card
Differential pairs pins connection, veneer receives the differential signal from plug-in card by the differential pairs pins, and combines the differential signal
Quality determine plug-in card slotting steady state detailed process.In conjunction with Fig. 3 and Fig. 4, this method be may include steps of:
S101: veneer receives the differential signal from the plug-in card by the differential pairs pins.
In the present embodiment, veneer is connect by differential pairs pins with plug-in card, and the signal transmitted between veneer and plug-in card is poor
Sub-signal.The differential pairs pins include two PIN, the two PIN are used for transmission that amplitude is identical, differential signal of opposite in phase.
Optionally, in the present embodiment, veneer can be connected by least four differential pairs pins, wherein at least four differential pair draws
Two of them differential pairs pins in foot are located on veneer, other two differential pairs pins is located on plug-in card.It is shown in Fig. 4
The case where veneer is connect by 4 differential pairs pins with plug-in card.
As shown in figure 4, veneer passes through the first differential pairs pins, the second differential pairs pins, third differential pairs pins and the 4th
Differential pairs pins are connect with plug-in card.Wherein, which is the A1 and A1 ' in Fig. 4, and the second differential pairs pins are figure
B1 and B1 ' in 4, third differential pairs pins are the A2 and A2 ' in Fig. 4, and the 4th differential pairs pins are the B2 and B2 ' in Fig. 4.It should
First differential pairs pins and the second differential pairs pins are located on veneer, and third differential pairs pins and the 4th differential pairs pins are positioned at slotting
On card, the first differential pairs pins are connect with third differential pairs pins, and second differential pairs pins are drawn with the 4th differential pair
Foot connection.
Optionally, a pair of of differential pair that the first differential pairs pins and the second differential pairs pins can be farthest for distance on veneer
Pin, third differential pairs pins and the 4th differential pairs pins can be a pair of of the differential pairs pins of distance on plug-in card farthest, in this way
Physical connection mode, can to avoid because veneer on differential pairs pins and plug-in card on differential pairs pins due to part pin
Be staggered generation the case where causing some differential pairs pins on veneer and plug-in card to be practically without docking, such as may refer to Fig. 5
Shown in pin the case where being staggered.In the case of fig. 5, even if having determined that plug-in card is in by differential signal inserts steady shape
State although plug-in card at this time is inserted surely, but is not docked with veneer actually completely, so occur inserting the feelings surely judged by accident
Condition.It but is a pair of of difference that distance is farthest on veneer by the first differential pairs pins of setting and the second differential pairs pins in Fig. 4
To pin, and setting third differential pairs pins are that a pair of of differential pair that distance is farthest on plug-in card draws with the 4th differential pairs pins
Foot, it is therefore intended that: if two farthest differential pairs pins of distance, two differential pairs farthest at a distance from plug-in card on veneer
Pin connection is accurate, then is located at the two on veneer apart from farthest differential pairs pins (i.e. the first differential pairs pins and second poor
Point to pin) between other differential pairs pins, with plug-in card on be located at farthest differential pairs pins (the i.e. third of above-mentioned two distance
Differential pairs pins and the 4th differential pairs pins) between other differential pairs pins can certainly will also connect accurately.Connected based on the physics
Mode is connect, if inserting steady state by following be in using differential signal Quality estimation plug-in card, the plug-in card can be directly determined
The judgement of slotting steady state be accurate.
It should be noted that the connection type of above-mentioned Fig. 4 is only a kind of example, four can also be passed through between veneer and plug-in card
A above differential pairs pins connection, the present embodiment is to this and without limitation.
Based on veneer with plug-in card in such a way that differential pairs pins connect, veneer can by differential pairs pins receive come from
In the differential signal of plug-in card, and know the quality of the differential signal.
S102: whether veneer meets the preset judging result for inserting steady condition according to the quality of the differential signal, determines
Whether the plug-in card being currently plugged on the veneer, which is in, is inserted steady state；Wherein, described to insert steady condition to enable to the list
AC impedance and DC impedance between plate and the plug-in card meet the condition of signal transfer impedance requirement.
Specifically, veneer judges whether the quality of the differential signal meets after veneer obtains the quality of differential signal
It is preset to insert steady condition, if satisfied, then veneer think the plug-in card being currently plugged on veneer be in insert steady state.This inserts steady condition
To enable to AC impedance between veneer and plug-in card and DC impedance to meet the condition of signal transfer impedance requirement.For example,
This, which inserts steady condition, can be research staff based on inserting under steady environment in the plug-in card that laboratory is built, by constantly detecting, surveying
The determining plug-in card that can characterize of examination inserts the standard quality of steady differential signal, or to obtain DC impedance and AC impedance between plate equal
The standard quality of differential signal in normal situation.It is inserted in steady judgement actual, if the differential signal that veneer obtains
Quality is less than the standard quality, just illustrates that the plug-in card being currently plugged on veneer is not slotting steady.The present embodiment is to inserting steady item
The specific manifestation form of part and without limitation, as long as under this condition, AC impedance and DC impedance between veneer and plug-in card
It is all satisfied the requirement of signal transfer impedance.Based on this, whether plug-in card when veneer is assured that out the biography differential signal between plate
In inserting steady state.
It should be noted that plug-in card is in and inserts steady state under the premise of plug-in card differential signal transmission between plate, then it can be with
When guaranteeing to transmit direct current signal between plate, plug-in card, which is also in, inserts steady state.This is because the DC impedance between plate meets
When the impedance transfer of direct current signal requires, AC impedance not necessarily serdes signal impedance transmission requirement；But when the friendship between plate
