Description

Technical Field

[0001] This application relates to the technical field of hard disk testing, and particularly relates to a reliability test fixture. Background Art

[0002] In the field of solid-state drive (SSD) reliability testing, especially for testing anti-vibration and anti-shock performance, the testing methods and techniques in related technologies face many challenges. SSD reliability testing is a key step to ensure its stable operation under various working conditions. These tests aim to simulate various situations that an SSD may encounter throughout its life cycle to verify its durability and performance stability. Since the verification of SSD reliability varies, for each verification test, a relatively reliable fixture is required to conduct reasonable tests. For the anti-vibration and anti-shock tests, the main purpose is to test the performance of the SSD when it is subjected to mechanical shock or vibration. The common method is to place the SSD on a vibration table that simulates the transportation or industrial environment and check its performance under these conditions.

[0003] The current reliability testing method is to directly fix the SSD on the impact and vibration table or a simple fixture through a thin pressure strip or tape for testing. Although this method can simply meet the testing requirements, there are many problems, which easily lead to poor testing results of the SSD reliability testing method. Specifically, first, the compressive stress on the SSD in this testing method is not easy to control, and it is easy to cause damage to the SSD body caused by non-test factors. And the impact test is triggered instantaneously with a large intensity, and the vibration test is random vibration, which easily causes the SSD to deviate from the ideal position during the impact, resulting in the actual acceleration not meeting the requirements during the test, leading to test failure and affecting time and cost. Second, the vibration test platform is large. In the case of simple pressure strip testing and when not tightly connected, it will also affect the relative position of the SSD and the vibration table. To sum up, if a reasonable and reliable test fixture is not used, the conventional method of conducting vibration and shock tests on the SSD will affect the accuracy of the final test results. Finally, most of the SSD reliability test fixtures on the market lack an avoidance position for the wiring harness connected to the SSD. The U.2 connection cable and PCIe adapter cable of the SSD are tightly connected, and the stable connection between the SSD and external devices (such as a PC) is not fully considered. It only supports vibration and shock tests in the non-working state, that is, tests when the SSD is not in the read / write operation mode, and cannot provide a test environment that can both fix the SSD and ensure its stable communication with external devices. This cannot effectively simulate the real failure mode of the SSD in the working state, easily causing interface loosening and even data read / write interruption. Although this method can initially evaluate the physical durability of the SSD in a static environment, it cannot reflect the response of the SSD to vibration and shock under actual workloads, and the practicality of the test results is limited, restricting the effectiveness and efficiency of the SSD product development and quality control stages.

[0038] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific implementation manners.

[0039] As Figures 1 to 13As shown in the figure, an embodiment of the present application provides a reliability test fixture, including: a fixture body 1, the fixture body 1 is a cuboid, one side of the fixture body 1 is provided with an installation groove 10 and a first opening 11 communicating with the installation groove 10, the installation groove 10 includes a connected first groove body 101 and a second groove body 102, the first groove body 101 is used to accommodate the component to be tested 3, and the second groove body 102 is used to accommodate the wiring component 4 connected to the component to be tested 3; a first pressing component 2, the first pressing component 2 is detachably arranged at the first opening 11 and is correspondingly arranged with the first groove body 101 to fix the component to be tested 3 in the first groove body 101; wherein, a plurality of test fixing holes 12 are further arranged on the fixture body 1, at least part of the plurality of test fixing holes 12 extend along the first direction and are spacedly arranged on two first side surfaces 13 of the fixture body 1, and the two first side surfaces 13 are oppositely arranged along the first direction.

[0040] Through the cooperation of the installation groove 10 including the first groove body 101 and the second groove body 102 and the first pressing component 2, the reliability test fixture of the present application ensures that the component to be tested 3 and the wiring component 4 can be stably fixed on the fixture body 1 during the test, avoiding test failure or data read / write interruption caused by loosening of the component to be tested 3 and the wiring component 4 or unstable wiring. And by setting a plurality of test fixing holes 12 for connecting with the to-be-installed positions on the test bench through test fasteners, the accuracy and reliability of the test are improved, and the test process can be made more stable, at least solving the problem of poor test effect in the reliability test method of solid-state drives in the related art. It is applicable to the anti-vibration and anti-impact tests of solid-state drives, especially the tests when the SSD is in the working state, such as tests on a vibration table simulating transportation or industrial environments.

[0041] Optionally, the component to be tested 3 is a solid-state hard disk, and the wiring assembly 4 is a PCIe adapter cable. The current fixture for reliability testing of solid-state hard disks lacks an avoidance position for avoiding the wiring harness connected to the SSD, and only supports power-off testing of the solid-state hard disk, that is, vibration and shock testing in a non-working state, but the U.2 connecting cable of the solid-state hard disk and the PCIe adapter cable cannot be tightly connected. When the solid-state hard disk is subjected to vibration and shock testing in a working state, the connection between the U.2 connecting cable and the PCIe adapter cable is prone to loosening, resulting in test interruption or error, which cannot effectively simulate the real failure mode of the SSD in a working state, and is prone to causing the interface to loosen or even cause data reading and writing interruption, resulting in test failure, affecting test time and cost. The fixture body 1 of the present application can fix the component to be tested 3 and the wiring assembly 4 in the mounting groove 10, which can not only maintain the stable connection between the component to be tested 3 and the wiring assembly 4 in a non-working state, but also effectively simulate the real working scene in a working state, and can enable the SSD to stably perform vibration and shock testing in a working state, reasonably and efficiently complete the test, and accurately test the reliability of the SSD.

[0042] In addition, the reliability test fixture of the present application sets the fixture body 1 as a rectangular parallelepiped, which has the following advantages:

[0043] (1) It provides good structural stability for the fixture body 1 and forms a stable support point, so that the fixture body 1 can maintain the firmness of the overall structure when subjected to vibration and impact tests, and is not prone to deformation or damage, providing a safe and reliable fixing component for the SSD.

[0044] (2) The geometric characteristics of the cuboid allow various fixing holes and grooves to be designed on different sides of the fixture body 1, such as the aforementioned mounting groove 10 and test fixing hole 12 as well as the mounting position of the first clamping component 2, so as to meet the testing requirements of the component to be tested 3.

[0045] (3) The rectangular parallelepiped has clear edges and corners, which facilitates quick alignment and installation between the fixture body 1 and the test equipment (such as a vibration table or an impact table), thereby improving the test efficiency and convenience.

[0046] (4) The rectangular shape is common in mechanical processing and is easy to process by cutting, drilling, milling and other processing techniques. This not only simplifies the manufacturing process of the fixture body 1, but also reduces the production cost, which is conducive to large-scale production and maintenance.

[0047] In summary, the selection of the cuboid as the basic structure of the fixture body 1 is based on its comprehensive advantages in stability, versatility, convenience, economy and compatibility, which is essential for achieving high-precision, high-efficiency, low-cost, safe and reliable vibration and shock testing of SSDs under various working conditions.

[0048] As Figure 2 、 Figure 3 and Figure 6 shown, the width of the first slot 101 is greater than the width of the second slot 102; and / or the depth of the first slot 101 is equal to the depth of the second slot 102. This can better adapt to the different size requirements of the component under test 3 and the wiring assembly 4. The larger width of the first slot 101 can accommodate the main body of the SSD, while the smaller width of the second slot 102 is more suitable for the wiring assembly 4. The design with equal depths of the first slot 101 and the second slot 102 ensures the stability of the component under test 3 and the wiring assembly 4 on the same plane, avoiding connection instability caused by depth differences and improving the compatibility of the test fixture and the connection stability during the test process.

[0049] Specifically, the size of the first slot 101 is matched with that of the component under test 3, so that the first slot 101 and the component under test 3 can be in close contact. Combined with the first pressing component 2, a stable and tight connection between the fixture body 1 and the component under test 3 can be achieved.

[0050] As Figure 2 、 Figure 3 and Figure 6 shown, the second slot 102 includes a first slot section 103 and a second slot section 104 that are sequentially connected in a direction away from the first slot 101. The first slot section 103 is used to accommodate the connector 41 of the wiring assembly 4, and the second slot section 104 is used to accommodate the connecting wire 42 of the wiring assembly 4. In this way, by separately arranging the connector 41 and the connecting wire 42 of the wiring assembly 4 in the first slot section 103 and the second slot section 104, the fixing of the wiring assembly 4 can be more finely controlled, improving the fixing accuracy and stability of the wiring assembly 4 and further ensuring the accuracy of the test.

[0051] Among them, the connector 41 is the connector of the U.2 wire harness for connecting to the solid-state drive body, and the connecting wire 42 is the connecting wire of the U.2 wire harness.

[0052] As Figure 2 、 Figure 3 and Figure 6 shown, the width of the first slot section 103 is greater than the width of the second slot section 104; and / or the depth of the first slot section 103 is equal to the depth of the second slot section 104. In this way, it can adapt to the different size requirements of the connector 41 and the connecting wire 42 of the wiring assembly 4. The larger width of the first slot section 103 can better accommodate the connector 41, while the smaller width of the second slot section 104 is suitable for the placement of the connecting wire 42. The design with equal depths of the first slot section 103 and the second slot section 104 ensures the stability of the connector 41 and the connecting wire 42 on the same plane, avoiding the instability of the connector 41 and the connecting wire 42 caused by depth differences and improving the fixing accuracy and stability of the wiring assembly 4.

[0053] Specifically, the dimensions of the first slot section 103 and the joint 41 are matched with each other so that the first slot section 103 and the joint 41 can be in close contact; the dimensions of the second slot section 104 and the connecting line 42 are matched with each other so that the second slot section 104 and the connecting line 42 can be in close contact.

[0054] As Figure 1 As shown, the first pressing member 2 includes a first pressing piece 21 and a plurality of first connecting fasteners 22. A plurality of first connecting through holes are provided on the first pressing piece 21. The plurality of first connecting through holes are arranged in one-to-one correspondence with the plurality of first connecting fasteners 22. The plurality of first connecting through holes are arranged at both ends of the first pressing piece 21 at intervals along the length direction of the first pressing piece 21; a plurality of first connecting fastening holes 16 are further provided on the jig body 1. The plurality of first connecting fastening holes 16 are arranged in one-to-one correspondence with the plurality of first connecting fasteners 22. The plurality of first connecting fastening holes 16 are arranged at both ends of the first slot body 101 at intervals along the width direction of the first slot body 101; wherein, one end of each first connecting fastener 22 passes through the corresponding first connecting through hole and is fixedly connected to the corresponding first connecting fastening hole 16. In this way, through the pressing force of the first pressing piece 21 and the fixing action of the plurality of first connecting fasteners 22, the stable fixing of the component 3 to be measured in the jig body 1 is ensured, avoiding the displacement or damage of the component 3 to be measured caused by vibration or impact, improving the fixing accuracy of the component 3 to be measured and the safety of the testing process, and making the test results more accurate and reliable.

[0055] Specifically, the first pressing piece 21 is a bar, and two first connecting through holes are provided on the first pressing piece 21. The two first connecting through holes are respectively located at both ends of the first pressing piece 21, and two first connecting fastening holes 16 are further provided on the jig body 1.

[0056] Furthermore, the number of the first pressing members 2 is two, and the two first pressing members 2 are respectively located at two trisection points of the first slot body 101 to achieve effective fixing of the component 3 to be measured.

[0057] As Figure 1As shown, the reliability test fixture further includes a second pressing member 5. The second pressing member 5 is detachably disposed at the first opening 11 and correspondingly disposed at the connection of the first groove section 103 and the second groove section 104 to fix the joint 41 and the connecting wire 42 in the first groove section 103 and the second groove section 104 respectively. In this way, through the pressing force of the second pressing member 5, the stable fixation of the joint 41 and the connecting wire 42 in the test fixture is ensured, avoiding the relative displacement or damage between the joint 41 and the connecting wire 42 caused by vibration or impact, improving the fixation accuracy between the component under test 3 and the wiring assembly 4 and the safety of the test process, facilitating the interaction with the host computer through the wiring assembly 4, realizing the shock and vibration test in the working state, and making the test results more accurate and reliable.

[0058] As Figure 1As shown in the figure, the second pressing member 5 includes a second pressing piece 51 and a plurality of second connecting fasteners 52. A plurality of second connecting through holes are provided on the second pressing piece 51. The plurality of second connecting through holes are arranged corresponding to the plurality of second connecting fasteners 52 one by one, and the plurality of second connecting through holes are arranged at both ends of the second pressing piece 51 at intervals along the length direction of the second pressing piece 51. A plurality of second connecting fastening holes 17 are further provided on the fixture body 1. The plurality of second connecting fastening holes 17 are arranged corresponding to the plurality of second connecting fasteners 52 one by one, and the plurality of second connecting fastening holes 17 are arranged at both ends of the second groove body 102 at intervals along the width direction of the second groove body 102. Wherein, one end of each second connecting fastener 52 passes through the corresponding second connecting through hole and is fixedly connected to the corresponding second connecting fastening hole 17. In this way, through the pressing force of the second pressing piece 51 and the fixing action of the plurality of second connecting fasteners 52, the present application ensures the stable fixation of the joint 41 and the connecting wire 42 in the test fixture, avoids the relative displacement or damage of the joint 41 and the connecting wire 42 caused by vibration or impact, improves the fixing accuracy of the joint 41 and the connecting wire 42 and the safety of the test process, and can effectively prevent the joint 41 and the connecting wire 42 from loosening or falling off due to external mechanical stress (such as vibration, pulling) during the test, ensuring that the data reading and writing of the SSD in the working state will not be interrupted, helping to reduce signal attenuation or interference caused by loosening, maintaining the integrity of data transmission, improving the reliability of the test and the stability of data transmission, and making the test results more accurate and reliable. In addition, when preparing for the test, the tester does not need to manually fix or wind the wire, which simplifies the preparation work before the test, saves time and energy, and at the same time reduces the risk of wire damage or poor interface contact caused by improper manual operation. When performing multi-directional tests, there is no need to re-organize or fix the wire when switching to each test direction. Just adjust the position of the fixture body 1 to perform the test in the next direction. This greatly shortens the test preparation time, improves the overall efficiency and smoothness of the test. It not only improves the accuracy and stability of the SSD reliability test at the technical level, but also simplifies the test process at the operation level, saves time and cost, and is an important technical guarantee for realizing efficient and accurate SSD reliability tests.

[0059] As Figures 1 to 13 shown, the plurality of test fixing holes 12 include a plurality of first test fixing holes 121. The plurality of first test fixing holes 121 extend along the first direction and are arranged at intervals on the two first side surfaces 13 of the fixture body 1. The two first side surfaces 13 are arranged opposite to each other along the first direction. In this way, by providing the first test fixing holes 121, the present application can stably fix the fixture body 1 on the vibration and shock test bench through the first test fasteners for testing the reliability of the SSD in the first direction, improving the fixing accuracy of the test fixture and the safety of the test process, and making the test results more accurate and reliable.

[0060] The fixture body 1 of the reliability test fixture of the present application includes two first side faces 13 arranged at intervals in the first direction.

[0064] Specifically, three second test fixing holes 122 are provided on each second side face 14. These three second test fixing holes 122 are arranged at intervals in the third direction. The middle second test fixing hole 122 is located at the center of the corresponding second side face 14, and the distances between the two second test fixing holes 122 on both sides and the middle second test fixing hole 122 are equal; the three second test fixing holes 122 on one second side face 14 and the three second test fixing holes 122 on the other second side face 14 are in one-to-one correspondence and communicate with each other.

[0065] As Figures 1 to 13 shown, the multiple test fixing holes 12 include multiple third test fixing holes 123. The multiple third test fixing holes 123 extend along a third direction and are spaced apart on two third side surfaces 15 of the jig body 1. The two third side surfaces 15 are oppositely arranged along the third direction. In this way, by providing the third test fixing holes 123 in the present application, the jig body 1 can be stably fixed on the vibration and shock test bench through the third test fasteners, so as to be used for testing the reliability of the SSD in the third direction, improving the fixing accuracy of the test jig and the safety of the test process, and making the test results more accurate and reliable.

[0066] The jig body 1 of the reliability test jig of the present application includes two third side surfaces 15 spaced apart along a third direction. Each third side surface 15 is a rectangular surface. Multiple third test fixing holes 123 are provided on one of the two third side surfaces 15, and multiple third test fixing holes 123 are also provided on the other of the two third side surfaces 15. The multiple third test fixing holes 123 provided on one third side surface 15 are arranged in one-to-one correspondence with the multiple third test fixing holes 123 provided on the other third side surface 15.

[0067] Specifically, three third test fixing holes 123 are provided on each third side surface 15. The three third test fixing holes 123 are spaced apart along a second direction. The middle third test fixing hole 123 is located at the center of the corresponding third side surface 15. The distances between the two third test fixing holes 123 on both sides and the middle third test fixing hole 123 are equal; the three third test fixing holes 123 on one third side surface 15 are in one-to-one communication with the three third test fixing holes 123 on the other third side surface 15.

[0068] By providing the first test fixing holes 121, the second test fixing holes 122 and the third test fixing holes 123 in the present application, the tests of the first direction, the second direction and the third direction of the jig body 1 can be realized. It only needs to rotate the jig body 1 without repeatedly disassembling and assembling the component 3 to be tested, which effectively improves the test efficiency and ensures the consistency of the test.

[0069] Among them, the first direction, the second direction and the third direction are perpendicular to each other in pairs.

[0070] In the reliability test jig of the present application, the first direction is the height direction of the jig body 1, the second direction is the length direction of the jig body 1, and the third direction is the width direction of the jig body 1.

[0071] In the reliability test fixture of the present application, by defining that the first direction, the second direction, and the third direction are perpendicular to each other pairwise, the spatial coordinate system of the fixture body is clarified. Furthermore, the intuitiveness and functionality of the fixture design are improved, and the fixture design can comprehensively cover the movement possibilities of the SSD in three-dimensional space, thereby providing solid physical support in tests in different directions and ensuring the constancy of the SSD position and the continuity of the interface connection in the test environment. This meticulous direction division and fixed-point layout not only increase the comprehensiveness and accuracy of the test but also make the operation of the entire test fixture more convenient. The reliability test in multiple directions can be completed without frequently adjusting the position of the SSD, effectively improving the test efficiency and reducing the test difficulty.

[0072] The solid-state drive (SSD) referred to in the present application belongs to the storage component of the computer hardware system. Specifically, it is a type of data storage device used to store and retrieve digital information. Compared with the traditional hard disk drive (HDD), the solid-state drive does not have mechanical components such as rotating disks and moving read / write heads. Instead, it uses NAND flash memory chips as the storage medium, which gives the solid-state drive obvious advantages in terms of startup speed, read / write speed, energy consumption, and shock resistance. The solid-state drive is usually regarded as the secondary storage device inside the computer, second only to the main memory (RAM), but much faster than the traditional hard disk drive, and is an essential component in modern computers, servers, laptops, and mobile devices.

[0073] In practical applications, this design method based on the three-dimensional coordinate system is not only suitable for the test of solid-state drives but can also be widely applied to the design of multi-directional vibration and shock test fixtures for other electronic devices or mechanical components, providing strong technical support for improving the scientificity and effectiveness of product reliability tests.

[0074] The usage method of the reliability test fixture of the present application is as follows:

[0075] First, fix the fixture body 1 on the vibration and shock test bench through the first test fixing hole 121, the second test fixing hole 122, and the third test fixing hole 123 for testing the first direction of the SSD; when testing the second direction subsequently, fix it on the vibration and shock test bench through the second test fixing hole 122, and when testing the third direction, fix it on the vibration and shock test bench through the third test fixing hole 123.

[0076] Then, place the SSD in the first slot 101 of the installation slot 10, and fix the SSD through the first pressing component 2; when testing in the working state, it is necessary to combine the PCIe adapter cable, connect the PCIe adapter cable to the U.2 female head of the SSD and place it in the second slot 102, and fix it with the second pressing component 5; then use the PCIe adapter cable to interact with the PC for business read and write operations on the SSD, truly simulating the scenarios of the SSD being vibrated and impacted in the working state.

[0077] The above has introduced in detail a reliability test fixture provided by the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application.
