As shown in Fig. 2, the selection of USB3.1Type C interface uses sunk type socket connector, for 2.5 cun, 7mm SSD
Design requirement, first connector of USB3.1Type C 204 run through pcb board 202, the part of perforative pcb board 202 needs to dig
Vacancy reason, 201 thickness of SSD upper casing, the first connector of 203 thickness of SSD lower casing, PCB202 plate thickness and USB3.1Type C
Total dimensional thickness is no more than the thickness of 2.5 cun of 7mmSSD, needs to consider the thickness of SSD entirety front and back sides shell, the thickness of pcb board
Degree and the top layer of pcb board and the height of bottom device select the USB3.1Type of suitable sinking size according to the actual situation
C connector.The utility model provides a kind of specific example, such as: for 7mm thickness SSD, consider SSD structural housing upper casing
201 and SSD structural housing lower casing, 203 thickness is 1.0mm respectively, pcb board 202 with a thickness of 1.2mm, then corresponding pcb board 202
The component limit for height height of upper top layer 206 and bottom 207 in 1.9mm, considers the first connector of sunk type USB3.1Type C
204 hollow out processing in the pcb board dashed region 205, then height limiting zone of the USB connector apart from shell needs in the region
Less than 1.9mm or so.Due to the sinking situation of the first connector of USB3.1Type C 204 of pcb board bottom, PCB below
Plate 202 need to hollow out processing, i.e., dashed region 205 in figure, and the outer cover height of such the first connector of USB3.1Type C 204 can
To occupy the thick a part of size of pcb board 202.
As shown in figure 3, the pin distribution in a center of symmetry of the upper and lower two sides of the first connector of USB3.1Type C,
The pin distribution in a center of symmetry of two sides above and below the second connector of USB3.1Type C.The second connector pinout of USB3.1Type C
Interface is defined with the first connector of USB3.1Type C.The characteristic for making full use of the positive anti-plug of USB Type C connector, by 2
Power supply signal, 5 JATG signals, 2 UART signals, 3 MCU programming debugging signals are reasonably allocated to the USB with 24 pins
In Type C connector, symmetrical signal is linked together, just insert in this way, anti-plug when, which also can be just
Often work.Table is the signal definition pin assignment situation of progress by taking 12 above-mentioned signals as an example in Fig. 3.According to different
The debugging interface of SSD controller or MCU, the interface quantity that may be occupied are different.Such as: the producer's SSD controller having is not required to
JATG interface is wanted, the load and debugging to mainboard program can be realized by UART interface；Some MCU only retain 2 signals
The programming debugging to MCU can be realized, SSD mainboard also is that do not have MCU unit, can flexibly be handled according to actual needs, example
When such as without MCU signal, respective pins can be not connected to.
Illustrate USB3.1Type C connector interface pin distribution situation to become apparent from, provides general same
The schematic diagram of USB3.1Type C connector two sides Pin locations up and down, as shown in figure 4, the first connector of USB3.1Type C and
The interface assignment of the second connector of USB3.1Type C is symmetrical using the positive anti-plug and interface of USB3.1Type C connector
Characteristic carries out signal definition.
When user is in the SSD mainboard debugging to 2.5 cun of 7mm or when upgrade maintenance, first passes through USB connecting line and meet SSD and open
It sends out in debugging apparatus；As needed, corresponding debugging interface is selected, PC host side is then connected to.It thus may be implemented not
In the case of tearing SSD shell open, checking for SSD mainboard data-printing information, the work such as program burn writing and test maintaining are realized.
2.5 cun of 7mmSSD exploitation debugging apparatus in technical solutions of the utility model can be used for other sizes form
The exploitation of SSD is debugged, such as 2.5 cun of 5mm, 9.5mm etc..Certainly when exploitation designs SSD mainboard, the type selecting USB3.1type C
Particular problem is needed to make a concrete analysis of when connector, such as 2.5 cun of 5mm SSD need the USB3.1type of type selecting custom-made size
C connector, and the shell sizes parameter of SSD and pcb board thickness are also required to according to requiring to be designed, but overall dimension otherwise it is super
Cross SSD disc thickness；2.5 cun of 19mm SSD use common USB3.1type C connector since the surplus of thickness is larger
It can access external exploitation debugging apparatus, similar with the utility model principle, details are not described herein for the utility model.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but it is not practical new to this
The limitation of type protection scope, those skilled in the art should understand that, based on the technical solution of the present invention, ability
Field technique personnel do not need to make the creative labor the various modifications or changes that can be made still in the protection model of the utility model
Within enclosing.
