Description

Technical Field

[0001] The present application relates to the technical field of solid state hard disk production equipment, and more specifically, to a test board structure of a solid state hard disk. Background Art

[0002] Solid State Drive (SSD) is widely used in various fields due to its powerful random read and write capabilities. The SSD can be installed on the host as the host's storage medium. The host sends data to the SSD so that the SSD writes the sent data into the SSD for storage. The main circuit parts of the SSD are the hard disk board and the outer shell. The hard disk board adopts the integrated circuit board method. When the hard disk board is produced, it is necessary to perform functional testing in time to see whether normal data storage can be performed. For example: In order to verify the reliability of the power-off protection function under abnormal conditions, the test tool is used to perform hundreds or thousands of frequent power-on and power-off and hot-swap simulation operations on the SSD.

[0003] Existing testing tools usually use a test circuit board for functional testing. The test circuit board usually has a horizontal connector, similar to the M2 solid-state drive interface on a computer motherboard. The solid-state drive to be tested is inserted into the horizontal connector in a direction parallel to the test circuit board. The solid-state drive to be tested is suspended parallel to the test circuit board. To improve the installation stability, the other end of the solid-state drive to be tested needs to be fixed. This makes it difficult to disassemble and assemble the solid-state drive to be tested during the test, affecting the test efficiency.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] like Figure 1 , Figure 2 , Figure 3As shown, this embodiment proposes a test board structure of a solid state hard disk, which is used to connect and test the solid state hard disk 10 to be tested. The solid state hard disk 10 to be tested in this scheme refers to the hard disk board part of the solid state hard disk, and does not include the hard disk shell part. When the hard disk board passes the test, the hard disk shell is installed to form a complete solid state hard disk. The test board structure mainly includes: a test circuit board 100, at least one auxiliary circuit board 200 and a vertical connection seat 300. At least one horizontal connection seat 110 is provided on the test circuit board 100, and the horizontal connection seat 110 can adopt a standard M.2 solid state hard disk socket or other solid state hard disk socket. At least one auxiliary circuit board 200 is provided with a docking gold finger part 210, and can be plugged and connected to the horizontal connection seat 110 through the docking gold finger part 210. At least one auxiliary circuit board 200 is docked with the horizontal connection seat 110 through the gold finger part, so that it is electrically connected to the test circuit board 100. The vertical connector 300 is arranged on the surface of the auxiliary circuit board 200 away from the test circuit board 100, which is equivalent to converting the horizontal connector 110 into a vertical plug-in vertical connector 300 through the auxiliary circuit board 200. The vertical connector 300 is used for pluggable connection belt detection of solid-state hard disks, so that the solid-state hard disk 10 to be detected is placed vertically on the test circuit board 100. The interface form of the vertical connector 300 can be the same as or different from the interface form of the horizontal connector 110. In the same case, the communication protocol does not need additional conversion, but in different cases, additional conversion is required to realize the communication connection function.

[0038] In this embodiment, a plurality of horizontal connection sockets 110 may be provided on a test circuit board 100, and a plurality of corresponding auxiliary circuit boards 200 may be provided, and may be plugged into the plurality of horizontal connection sockets 110 in a one-to-one correspondence. In this way, a plurality of solid state drives 10 to be tested may be tested simultaneously on a test circuit board 100, and the test efficiency of the solid state drives may be improved.

[0039] By setting an auxiliary circuit board 200 on the test circuit board 100, the auxiliary circuit board 200 is inserted into the original horizontal connecting seat 110 on the test circuit board 100 through the docking gold finger part 210, so that the auxiliary circuit board 200 and the test circuit board 100 are electrically connected, and the function of the vertical connecting seat 300 on the auxiliary circuit board 200 is the same as that of the original horizontal connecting seat 110. The vertical connecting seat 300 is used for pluggable connection belt detection of solid-state hard disks, so that the solid-state hard disk 10 to be tested can be placed vertically on the test circuit board 100. Taking the horizontal placement of the test circuit board 100 as an example, in the original test process, the solid state hard disk 10 to be tested needs to be inserted from one side into the horizontal connection seat 110 along the horizontal direction, and because the horizontal connection seat 110 only fixes one end of the solid state hard disk 10 to be tested, and the other end of the solid state hard disk 10 to be tested is in a suspended active state, in order to improve the stability during the test process, it is usually necessary to fix the other end of the solid state hard disk 10 to be tested with screws, so that the solid state hard disk 10 to be tested is stably connected to the test circuit board 100 in a horizontal state during the test process. After the test is completed, if the solid state hard disk 10 to be tested needs to be removed, the rear end screws need to be removed, and the solid state hard disk 10 to be tested needs to be pulled out from the horizontal connection seat 110 along the horizontal direction. With the test board structure of the solid state hard disk of this scheme, it is only necessary to insert the solid state hard disk 10 to be tested from top to bottom into the vertical connection seat 300, so that the solid state hard disk 10 to be tested can be stably connected to the test circuit board 100 for testing, so that the solid state hard disk 10 to be tested, which was originally lying flat on the test circuit board 100, is changed to a vertical plug-in mode. The vertically plugged solid state drive 10 to be tested is not only convenient for plugging and unplugging, but also avoids suspending the long solid state drive 10 to be tested in the horizontal direction, so it can be stably fixed without fixing at the other end, thereby facilitating loading and unloading for test personnel and improving test efficiency.

[0040] like Figure 1 , Figure 4As shown, further, the vertical connection seat 300 of this embodiment includes: a connector 310 and a guide shell 320. The connector 310 is arranged on the surface of the auxiliary circuit board 200, and the side of the connector 310 facing away from the auxiliary circuit board 200 has a plug-in opening 311, and the plug-in opening 311 is used to plug in the solid-state hard disk 10 to be tested. The guide shell 320 is arranged on the outside of the plug-in opening 311, and is used to guide the solid-state hard disk 10 to be tested to be plugged into the connector 310. In the specific structure, the connector 310 can adopt a standard connector 310 structure, which is mainly used to dock with one end of the gold finger on the solid-state hard disk 10 to be tested to achieve electrical connection, and the solid-state hard disk 10 to be tested can be connected to the detection system. The guide shell 320 arranged on the outside forms a circle around the plug-in opening 311, and the guide shell 320 protrudes a certain height from the auxiliary circuit board 200, so that a larger portion of the solid-state hard disk 10 to be detected is inserted into the vertical connecting seat 300. Therefore, even if the solid-state hard disk 10 to be detected shakes, the outer side of the solid-state hard disk 10 to be detected can be limited by the higher outer wall of the guide shell 320 to ensure the stability of the connection.

[0041] like Figure 4 As shown, further, the guide shell 320 of this embodiment includes: a shell 321 and elastic sheets 330 on both sides. The shell 321 is arranged around the outside of the plug-in opening 311, and the shell 321 has a guide opening 322. The inner walls on the left and right sides of the guide opening 322 are arranged obliquely, so that the guide opening 322 is in a form of being large outside and small inside. In this way, when the solid-state hard disk 10 to be detected is inserted into the vertical connection seat 300, the solid-state hard disk 10 to be detected is guided by the inclined inner walls on both sides of the guide opening 322 to center the solid-state hard disk 10 to be detected, making the insertion process of the solid-state hard disk 10 to be detected more convenient. The elastic sheets 330 are symmetrically arranged on the inner wall of the shell 321. The elastic sheets 330 on both sides generate elastic force toward the connector 310 through the extrusion of the solid-state hard disk 10 to be detected, and the solid-state hard disk 10 to be detected is extruded toward the connector 310 by the elastic force on both sides. When the solid state drive 10 to be tested is inserted into the connector 310, the elastic sheet 330 not only abuts against and limits the left and right sides of the solid state drive 10 to be tested, but also applies a certain downward squeezing force, so that the solid state drive 10 to be tested can be stably squeezed during the detection process after connection and the connection is more stable.

[0042] like Figure 3 , Figure 4As shown in the specific structure, the inner cavity of the guide shell 320 is used to insert the solid state hard disk 10 to be detected, and spring clip installation grooves 323 are opened in the inner walls on the left and right sides of the inner cavity, and a spring clip extension opening 324 facing the middle inner cavity is arranged above the spring clip installation groove 323. The elastic sheet 330 is arranged in the spring clip installation groove 323 and is bent upward to protrude toward the spring clip extension opening 324. Therefore, the upper side of the spring clip extension opening 324 needs a spring clip guide surface 325, and the spring clip guide surface 325 is arranged obliquely. When the solid state drive 10 to be detected is inserted from above and squeezes the elastic sheet 330, the elastic sheet 330 not only deforms toward the left and right sides but also deforms downward. Since the spring sheet guide surface 325 is inclined, the elastic member can be squeezed to the left and right sides by the solid state drive 10 to be detected to make way and be accommodated in the spring sheet extension port 324, so that the solid state drive 10 to be detected can be smoothly inserted downward into the inner cavity of the guide shell 320 and plugged into the connector 310. At this time, the elastic sheet 330 that is deformed downward has no squeezing from above by the solid state drive 10 to be detected, so that it generates an elastic force for upward recovery through the deformation amount previously compressed downward. The upward recovery trend causes the elastic sheet 330 to generate an inclined squeezing force along the spring sheet guide surface 325. Since the elastic guide surface 335 is inclined, the direction of the squeezing force is toward the outside of the spring sheet extension port 324, thereby squeezing the solid state drive 10 to be detected located in the inner cavity.

[0043] like Figure 3 , Figure 4 As shown, in order to achieve the above functions, the elastic sheet 330 in this embodiment specifically includes: a folded elastic portion 331, an extended connection portion 332, an arc-shaped bent portion 333, and a bent protrusion 334. The folded elastic portion 331 has good elasticity, for example, a multi-section wavy folded elastic plate is used, and the folded elastic portion 331 is arranged in the spring sheet installation groove 323. The extended connection portion 332 can be set as a straight sheet, which is connected to one end of the folded elastic portion 331 and extends a predetermined length in a direction away from the auxiliary circuit board 200. The arc-shaped bent portion 333 is connected to one end of the extended connection portion 332 away from the folded elastic portion 331, and extends toward the spring sheet extension port 324 after bending, and its arc surface abuts against the spring sheet guide surface 325. The bent protrusion 334 is connected to one end of the arc-shaped bent portion 333 away from the extended connection portion 332, and extends a predetermined length toward the center of the inner cavity.

[0044] like Figure 3 , Figure 4As shown, when the solid state hard disk 10 to be detected is inserted from the top, it first squeezes the bent protrusion 334 located in the inner cavity. After being subjected to the force, the bent protrusion 334 is pressed downward and deformed toward the left and right sides. The downward pressure compresses the folded elastic portion 331, so that the entire elastic sheet 330 is shortened in the up and down directions. Since the spring sheet guide surface 325 is inclined, the arc-shaped bent portion 333 makes way under the spring sheet guide surface 325 during the downward pressing process, so that the bent protrusion 334 compressed in the left and right directions can be squeezed to the left and right sides by the solid state hard disk 10 to be detected, and the bent protrusion 334 is squeezed and accommodated in the spring sheet extension port 324, so that the solid state hard disk 10 to be detected can be smoothly inserted downward into the inner cavity of the guide shell 320 for plugging with the connector 310. At this time, the folded elastic portion 331 that is deformed downwards generates an elastic force to recover upwards because there is no downward squeezing of the SSD 10 to be detected from above. During the recovery process, the arc-shaped bent portion 333 generates an inclined squeezing force along the spring sheet guide surface 325. Since the elastic guide surface 335 is inclined, the arc-shaped bent portion 333 tends to recover upwards and generates squeezing force toward the outside of the spring sheet extension opening 324, thereby squeezing the bent protrusion 334 to the SSD 10 to be detected in the inner cavity. The SSD 10 to be detected is pressed on both sides, and since the elastic guide surface 335 gradually tilts away from the center of the inner cavity from top to bottom, the elastic sheet 330 also has a certain downward squeezing force under the action of the inclined elastic guide surface 335, which is more conducive to stably connecting the SSD 10 to be detected in the connector 310.

[0045] like Figure 3 , Figure 4 As shown, further, the bending protrusion 334 of this embodiment can be a bending spring sheet, and the bending protrusion 334 can be tilted to apply a greater elastic force downward to the solid state hard disk 10 to be detected. In the structure, the bending protrusion 334 as a whole gradually approaches the center line of the inner cavity from top to bottom. The bending protrusions 334 tilted on the left and right sides form a funnel shape with a large upper end and a small lower end. In this way, not only when the solid state hard disk 10 to be detected is inserted, the tilted bending protrusion 334 is squeezed, the funnel-shaped opening guides the solid state hard disk 10 to be detected, and the solid state hard disk 10 to be detected enters along the center line, thereby achieving more accurate insertion; and after the solid state hard disk 10 to be detected is inserted, the bending protrusions 334 on the left and right sides are squeezed onto the outer wall of the solid state hard disk 10 to be detected, generating a larger downward component force, so that the solid state hard disk 10 to be detected is more stably inserted into the connector 310, ensuring a more stable electrical connection between the solid state hard disk 10 to be detected and the detection system during the test process.

[0046] like Figure 3 , Figure 4As shown, further, the front end of the bent protrusion 334 in this embodiment is provided with a trimming portion 336. The trimming portion 336 can increase the extrusion length with the outer wall of the solid state drive 10 to be detected, thereby improving the force stability at the junction of the bent protrusion 334 and the outer wall of the solid state drive 10 to be detected.

[0047] The edge trimming portion 336 at the front end can be in various forms, such as an inner curling edge, an inner bending edge, etc. The edge trimming portion 336 in this embodiment can be bent toward the edge trimming piece, and the front end of the bent protrusion 334 can be bent downward and then extended in a direction away from the center of the inner cavity, and can be extended to connect to the arcuate bending portion 333. Not only does it achieve the edge trimming function, but it also forms a reinforced support between the bent protrusion 334 and the arcuate bending portion 333, effectively improving the structural strength.

[0048] like Figure 3 , Figure 4 As shown, further, an insulating heat-insulating sheet 400 is provided between the test circuit board 100 and the auxiliary circuit board 200 of this embodiment. The insulating heat-insulating sheet 400 prevents the risk of short circuit caused by contact between the circuits or solder joints on the two circuit boards between the test circuit board 100 and the auxiliary circuit board 200, making the detection circuit more stable during use.

[0049] like Figure 3 , Figure 4 As shown, further, the insulating and heat-insulating sheet 400 of this embodiment adopts a hard insulating partition, the hard insulating partition has a predetermined thickness, the hard insulating partition is fixed on the surface of the auxiliary circuit board 200 facing the test circuit board 100, and the hard insulating partition is against the test circuit board 100. The hard insulating partition is not easy to be deformed by pressure, so that the test circuit board 100 and the auxiliary circuit board 200 arranged above and below are connected into a whole, and the hard insulating partition can prevent the auxiliary circuit board 200 from being deformed by pressure during the insertion of the solid-state hard disk 10 to be tested.

[0050] like Figure 1 , Figure 3 , Figure 5 As shown, further, the test board structure of this embodiment also includes a fixedly arranged downward pressing support member 500, which is connected to the auxiliary circuit board 200 and is used to push the auxiliary circuit board 200 toward the test circuit board 100. Since the auxiliary circuit board 200 below is also subjected to an upward force during the process of the solid state hard disk 10 to be tested being pulled out, such multiple plugging and unplugging can easily cause the position of the docking gold finger portion 210 of the auxiliary circuit board 200 and the horizontal connection seat 110 to become loose, especially when the vertical connection seat 300 is very close to the docking gold finger portion 210. Therefore, a downward squeezing force is applied to the auxiliary circuit board 200 by the downward pressing support member 500, so as to ensure the stability of the electrical connection between the auxiliary circuit board 200 and the test circuit board 100.

[0051] like Figure 3 , Figure 5 As shown, further, the pressing support member 500 of this embodiment specifically includes: a support frame 510, an elastic force member 520 and a pressing block 530. The support frame 510 protrudes from the surface of the test circuit board 100. Usually, the test circuit board 100 is fixed on the test machine. The support frame 510 can also be fixed on the test machine. For example, there is a boss on the test machine, and the test circuit board 100 is fixed on the boss, and a through hole is opened at the position of the boss. The support frame 510 can be fixed on the test machine by passing a screw through the through hole, and is located above the test circuit board 100. The elastic force member 520 is connected to the support frame 510. The elastic force member 520 can be a pressure spring. The pressing block 530 is movably arranged on the support frame 510 and connected to the elastic force member 520. The pressing block 530 is pressed against the surface of the auxiliary circuit board 200 by the elastic force of the elastic force member 520.

[0052] like Figure 2 , Figure 3 As shown, further, in this embodiment, multiple vertical connection seats 300 are arranged side by side and spaced apart along the extension direction of the auxiliary circuit board 200, and the multiple vertical connection seats 300 are electrically connected to the test circuit board 100 through the docking gold finger part 210. Multiple vertical connection seats 300 can be used to simultaneously plug multiple solid-state hard disks 10 to be tested. During the detection process, a detection program can be set, and through the detection program, multiple solid-state hard disks 10 to be tested on the multiple vertical connection seats 300 are detected in turn. In this way, multiple solid-state hard disks can be tested at one time, which improves the detection efficiency.

[0053] Furthermore, the models of the plurality of vertical connection sockets 300 of this embodiment are different, and the vertical connection sockets 300 of different models are used to connect the solid-state hard disks 10 to be detected with different interfaces. There are many forms of existing solid-state hard disk interfaces, such as mSATA, NVMe, M.2, PCI-E, etc. In this way, the auxiliary circuit board 200 becomes a converter, which can realize the detection of more types of solid-state hard disks.

[0054] like Figure 1 , Figure 3 As shown, further, the vertical connection seat 300 of this embodiment is provided with an end fixing position 220, and the end fixing position 220 is fixed to the test circuit board 100. Usually, the auxiliary circuit board 200 adopts a long strip shape, and the docking gold finger part 210 is arranged at one end, and the end surface fixing position is arranged at the other end of the auxiliary circuit board 200. For example, a screw is passed through the end fixing position 220 to connect to the test machine.

[0055] In summary, the test board structure of a solid-state hard disk proposed in this application changes the original solid-state hard disk to be tested lying flat on the test circuit board into a vertical plug-in mode. The vertical plug-in solid-state hard disk to be tested is not only convenient for plugging and unplugging, but also avoids suspending the long strip solid-state hard disk to be tested in the horizontal direction, so it can be stably fixed without fixing it at the other end. This makes it convenient for testers to load and unload and improves test efficiency.

[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
