Description

Technical Field

[0001] This utility model relates to the field of solid-state drive test fixture technology, specifically a test fixture for solid-state drives. Background Technology

[0002] Solid-state drives (SSDs), also known as solid-state drives, are hard drives made using arrays of solid-state electronic storage chips. An SSD can be understood as a high-speed, internally mounted USB flash drive with extremely large capacity. Because it lacks the mechanical components required by a mechanical hard drive (such as drives), and there are no moving parts within the drive itself, it is called a solid-state drive. After production, SSDs undergo testing, which requires the use of clamps to hold them in place. However, current testing clamps typically only hold one fixed drive at a time, offering limited functionality.

[0003] A search revealed a hard disk testing fixture with publication number CN221175398U, comprising: a fixture body; the fixture body includes a base plate, a first side plate, a second side plate, and a third side plate, the first side plate, the second side plate, and the third side plate being disposed on the upper surface of the base plate; one end of the third side plate being connected to the first side plate, and the other end of the third side plate being connected to the second side plate; the first side plate, the second side plate, and the third side plate forming a receiving groove; a cable fixing assembly, a connector fixing assembly, and a hard disk fixing strip are also sequentially disposed on the base plate; the hard disk fixing strip is disposed on the side close to the third side plate. This technical solution also suffers from the aforementioned technical problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6A test fixture for solid-state drives includes a base plate 6 forming a counterweight base. An electric push rod 8 providing linear driving force is mounted on the top of the base plate 6. A tension sensor 9 is fixedly mounted on the output axis of the electric push rod 8. The tension end of the tension sensor 9 is connected to a motion plate 11 via a drive rod 10. The tension sensor 9 is used to monitor the tension provided by the electric push rod 8. Vertical rods 12 are fixedly connected to the left and right sides of the top of the motion plate 11. The top ends of the two vertical rods 12 are fixedly connected by a pressure plate 3. Five connecting rods 4 are evenly arranged at the bottom of the pressure plate 3. A disc-shaped pressure block 5 is fixedly connected to the bottom of each connecting rod 4. A rubber pad 20 is fixedly adhered to the bottom of the pressure block 5. The pad 20 is designed to prevent... The design eliminates the need for rigid pressing and protects the solid-state drives. To stabilize the movement trajectory of the motion plate 11, two stabilizing telescopic rods 19 are fixedly connected to the bottom of the motion plate 11. The stabilizing telescopic rods 19 can extend and retract, and their bottom ends are fixedly connected to the top of the base plate 6. The two stabilizing telescopic rods 19 ensure that the motion plate 11 will only perform linear lifting and lowering movements, thus protecting the electric push rod 8. The electric push rod 8 and the structure connected to its output shaft constitute a pressing component, which also contains multiple pressing blocks 5. These pressing blocks 5 can press down on multiple solid-state drives, and their movement is achieved through a single electric push rod 8. This ensures the synchronous movement of the multiple pressing blocks 5, and the use of a single electric push rod 8 saves on manufacturing costs.

[0018] Two vertically extending support columns 7 are fixedly connected to the top of the base plate 6. The tops of the two support columns 7 are fixedly connected by a fixing plate 1. Five receiving slots 2 are equally spaced on the top of the fixing plate 1. The receiving slots 2 correspond one-to-one with the pressure blocks 5. The receiving slots 2 are used to place solid-state drives. A backing plate 13 is fixedly connected to the bottom of the inner wall of the receiving slot 2. Only two sides of the backing plate 1 are fixedly connected to the fixing plate 1, that is, the bottom and one side. This means that one side of the backing plate 13 is not attached to the fixing plate 1. When placing the solid-state drive into the receiving slot 2, the back side of the solid-state drive must be in contact with the front side of the backing plate 13. And when one side of the solid-state drive is attached to the backing plate 13, the gold finger insertion end of the solid-state drive will extend beyond the receiving slot 2.

[0019] To ensure that the pressure block 5 presses down on the solid-state drive, one side of each solid-state drive is attached to the fixing plate 1. A synchronizing rod 14 is movably connected to the fixing plate 1 and passes through the receiving groove 2. Five side plates 15 are fixedly connected to the surface of the synchronizing rod 14, and the sides of the side plates 15 are attached to the side of the back plate 13. A limiting plate 16 is fixedly connected to the end of the synchronizing rod 14 outside the fixing plate 1. A limiting telescopic rod 17 is fixedly connected to the side of the limiting plate 16. The end of the limiting telescopic rod 17 away from the limiting plate 16 is fixedly connected to the fixing plate 1. A spring 18 is sleeved on the surface of the limiting telescopic rod 17. One end of the spring 18 is fixedly connected to the limiting plate 16, and the other end is fixedly connected to the fixing plate 1. The spring 18 is in a stretched state as shown in the figure, and the spring 18 has a tendency to drive the limiting plate 16 to move closer to the fixing plate 1. (See the attached instruction manual.) Figure 2 As you can see, the space formed by the side plate 15, the back plate 13, and the inner wall of the receiving slot 2 is smaller than the size of the solid-state drive (SSD). Therefore, when it is necessary to place the SSD into the receiving slot 2, the operator can first pull the limiting plate 16. The limiting telescopic rod 17 and the spring 18 will extend, and the limiting plate 16 will pull the five side plates 15 simultaneously through the synchronizing rod 14. In this way, the space formed by the side plate 15, the back plate 13, and the inner wall of the receiving slot 2 will become larger. The SSD is placed in this space, and the limiting plate 16 is released. The spring 18 will pull the limiting plate 16 to move closer to the fixing plate 1, and the side plates 15 will push and squeeze the SSD. This ensures that one side of the SSD is in contact with the side of the inner wall of the receiving slot 2, ensuring that each SSD is neatly arranged when pressed and fixed by the pressure block 5.

[0020] A groove is provided on the top of the base plate 6. A track 21 is fixedly connected to the inner wall of the groove. A slider 22 is slidably connected to the surface of the track 21. The vertical cross-section of the track 21 is rectangular. This arrangement of the track 21 ensures that the slider 22 only slides back and forth on the surface of the track 21 and does not rotate. A bearing 23 is installed in the groove at the top of the slider 22. A threaded cylinder 24 is installed on the inner wall of the bearing 23. The outer ring of the bearing 23 is fixedly connected to the slider 22, and the inner wall of the inner ring of the bearing 23 is fixedly connected to the surface of the threaded cylinder 24. The bearing 23 allows the threaded cylinder 24 to rotate relative to the slider 22 while preventing it from detaching from the slider 22. A threaded rod 25 is threadedly connected to the inner wall of the threaded cylinder 24. A test strip 26 is fixedly connected to the top of the threaded rod 25, allowing the threaded cylinder 24 and the threaded rod 25 to rotate relative to each other. The height of the test strip 26 can be adjusted. The test strip 26 is a socket used with the gold fingers of the solid-state drive. The test strip 26 also has five insertion points, which are fixed to the... To prevent the test strip 26 from rotating, two positioning telescopic rods 27 are fixedly connected to the bottom of the test strip 26. The positioning telescopic rods 27 can extend or shorten, and their bottom ends are fixedly connected to the top of the slider 22. The positioning telescopic rods 27 are set to prevent the test strip 26 from rotating without affecting its lifting and lowering movement. Since the threaded cylinder 24 and the threaded rod 25 are threadedly connected, the height of the test strip 26 can be adjusted. This is to accommodate special solid-state drives with different thicknesses, where the position of the gold fingers may change. To prevent the threaded cylinder 24 and the threaded rod 25 from rotating relative to each other due to accidental movement, a stabilizing ring 29 is threadedly connected to the surface of the threaded rod 25. After adjusting the height of the test strip 26, hold the threaded cylinder 24 and rotate the stabilizing ring 29. The bottom of the stabilizing ring 29 will tightly press against the top of the threaded cylinder 24, thus locking the threaded cylinder 24 and the threaded rod 25.

[0021] Finally, to improve the automation level of the entire test fixture, a controller 28 electrically connected to the electric push rod 8 is installed on the top of the base plate 6. The controller 28 is a PLC controller, model Siemens S7-1200. The controller 28 controls the operation and stop of the electric push rod 8. The controller 28 is electrically connected to the tension sensor 9. The data transmitted by the tension sensor 9 is monitored by the controller 28. For example, when the force value transmitted by the tension sensor 9 is A, and the value A is just right to ensure the stability of the solid-state drive pressing without damaging the solid-state drive, the controller 28 will control the electric push rod 8 to stop pulling the moving plate 11 downward. In addition, the settings of the controller 28 and the tension sensor 9 can also effectively avoid the above force value being greater than A.

[0022] In use, pull the limiting plate 16 to place the five solid-state drives (SSDs) into the five receiving slots 2 respectively. Release the limiting plate 16, and the spring 18 will drive the limiting plate 16 to move closer to the fixed plate 1. The limiting plate 16 will drive the side plate 15 to move through the synchronizing rod 14. The side plate 15 will initially push and squeeze the SSDs. 28 controls the electric push rod 8 to work. The electric push rod 8 will drive the moving plate 11 to move downward through the tension sensor 9 and the driving rod 10. The moving plate 11 will drive the pressure plate 3 to move downward through the vertical rod 12. Finally, the pressure block 5 and the soft pad 20 will press on the top of the SSD. After that, the threaded cylinder 24 can be pushed backward, and the slider 22 will slide on the surface of the track 21. The gold fingers of the SSD will be inserted into the socket on the test strip 26, so that the test can be performed.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
