Description

Technical Field

[0001] The utility model relates to the technical field of hard disk testing, in particular to an oscilloscope probe fixing fixture for plug-in testing. Background Art

[0002] During the R&D phase of solid-state drives, compatible servers are used for testing to verify the reliability of inter-board signal SI. When using an oscilloscope to test the insertion and removal of disks, it is necessary to test whether the high-speed signal, power signal, and control signal meet the SI requirements. The existing inter-board signal testing operation generally adds an extension cable between the server and the SSD to test the signal status during the insertion and removal state. That is, the SSD insertion and removal scenario is simulated by plugging and unplugging the extension cable. However, manual operation when plugging and unplugging the cable will introduce artificial jitter, and the probe will also shake during plugging and unplugging, resulting in it not being completely equivalent to the smooth insertion and removal of the actual hard drive bracket. This will cause the inter-board signal to not accurately reflect the actual signal status, making the test reliability poor. Utility Model Content

[0026] See also Figure 1 In the specific embodiment shown, the utility model discloses an oscilloscope probe fixing fixture for plug-in and pull-out testing, including: a hard disk body 10, a fixture plate 20 and a probe part 30, the fixture plate 20 is connected to the hard disk body 10, the probe part 30 is fixed to the fixture plate 20, and the hard disk body 10 is electrically connected to the probe part 30 through a signal line 40 to perform plug-in and pull-out testing on the hard disk body 10.

[0027] Specifically, by connecting the fixture plate 20 to the hard disk body 10, and then directly fixing the probe member 30 to the fixture plate 20, and directly connecting it to the hard disk body 10 via the signal line 40, the use of an extension cable is avoided, thereby reducing the impact of jitter and the impact of plugging and unplugging the extension cable. The signal integrity (SI signal) of the solid-state drive during the plugging and unplugging process can be more accurately evaluated, thereby improving the reliability of the solid-state drive plugging and unplugging test. In addition, in the plugging and unplugging test of the solid-state drive, the evaluation of signal integrity (SI signal) is a key indicator. By providing a stable test environment and reducing external interference, this design can more accurately evaluate the reliability of the SI signal during the plugging and unplugging process, thereby providing more reliable test data for the design and manufacture of solid-state drives.

[0028] In one embodiment, the fixture plate 20 is provided with at least one pressing condition 50 , and the probe member 30 is located below the pressing condition 50 to form a fixed state.

[0029] Specifically, the pressure condition 50 provided on the fixture plate 20 can ensure that the probe member 30 is firmly fixed in the desired position. This fixed state can effectively prevent the probe member 30 from shaking or shifting during the test process, thereby ensuring the accuracy and reliability of the test. In addition, because the probe member 30 is firmly fixed, the test signal can be collected more accurately, avoiding signal distortion or error caused by the shaking of the probe member 30, which helps to improve the precision and accuracy of the test and make the test results more reliable. In addition, the firm fixed state can ensure the smooth progress of the test process, avoiding test interruption or repeated testing caused by the shaking of the probe member 30, which helps to improve test efficiency and reduce test time and cost.

[0030] In one embodiment, the pressure element 50 and the probe element 30 are arranged in a cross pattern.

[0031] Specifically, the pressure condition 50 and the probe member 30 are arranged in a cross-shaped arrangement, forming a stable fixed structure. This structure can ensure that the probe member 30 is firmly fixed in multiple directions, thereby greatly reducing the possibility of the probe member 30 shaking during the test process. The improved stability helps to ensure the accuracy and reliability of the test results, because a shaking probe member 30 may cause signal distortion or error. In addition, because the probe member 30 is firmly fixed, the test signal can be collected more accurately. This high-precision test is crucial for evaluating the signal integrity (SI signal) during the plug-in and unplugging process of the solid-state drive. In addition, the cross-shaped distribution design also helps to reduce the noise and interference generated by the shaking of the probe member 30, thereby further improving the precision and accuracy of the test.

[0032] In one embodiment, the number of the pressing members 50 is two.

[0033] Specifically, two pressure conditions 50 act on the different parts of the probe part 30 respectively, forming a kind of dual fixed structure, this structure can more effectively prevent the probe part 30 from shaking or shifting during the test, thereby ensuring the accuracy and reliability of the test. In addition, when the probe part 30 is fixed by two pressure conditions 50 at the same time, its stress can be more balanced, which helps to reduce the risk of the probe part 30 deformation or damage caused by uneven stress, and also helps to improve the stability of the test. In addition, a stable fixed state can ensure that the probe part 30 always keeps the correct position and angle during the test, thereby reducing the error caused by shaking, and this high-precision test is most important for evaluating the signal integrity (SI signal) in the solid-state drive plug-in process. In addition, a stable fixed state can ensure the smooth progress of the test process, avoids the test interruption or repeated test caused by the shaking of the probe part 30, and this helps to simplify the test process, reduces test time and cost. Because the test process is more stable and reliable, test results can be obtained faster, thereby improving test speed, which is particularly important for the test scene that needs to quickly evaluate the plug-in performance of the solid-state drive.

[0034] In one embodiment, both ends of the pressing member 50 are connected to the fixture plate 20 by screws.

[0035] Specifically, by screw connection, the pressure condition 50 can be easily fixed on the fixture plate 20, and can also be quickly released. This design makes the disassembly and assembly of the probe part 30 very simple and convenient, without the need for complicated operating steps or tools. In addition, the design of the screw connection allows the tester to quickly replace or adjust the probe part 30, thereby improving the efficiency of the test work, which is particularly important for frequently replacing the probe part 30 or switching between different test scenarios. In addition, the screw connection is a very reliable connection method that can ensure the tight connection between the pressure condition 50 and the fixture plate 20. This tight connection helps to prevent the probe part 30 from shaking or shifting during the test, thereby ensuring the accuracy and reliability of the test. In addition, by adjusting the tightness of the screw, it is possible to adapt to probe parts 30 of different sizes and weights, ensuring that they can all be firmly fixed on the fixture plate 20. This flexibility makes the fixture applicable to a variety of test scenarios and probe part 30 types.

[0036] In one embodiment, the pressing member 50 is made of plastic.

[0037] Specifically, plastic materials are usually very light, which allows the pressure condition 50 made of plastic to significantly reduce the weight of the entire oscilloscope probe part 30 fixing fixture. This is especially important for scenarios where test equipment needs to be frequently moved or carried, and can reduce the burden on operators and improve the flexibility and convenience of testing. In addition, plastic materials have excellent corrosion resistance and can maintain the stability of their physical and chemical properties in a variety of harsh environments. This means that the pressure condition 50 made of plastic can be used for a long time in humid, high-temperature, corrosive environments without being easily damaged, thereby extending the service life of the fixture. In addition, plastic materials are good insulating materials that can block the flow of current. In the oscilloscope probe part 30 fixing fixture, good insulation needs to be maintained between the pressure condition 50 and the probe part 30 and the circuit under test to prevent current leakage or short circuit. The pressure condition 50 made of plastic material can meet this requirement and ensure the safety and accuracy of the test process.

[0038] In one embodiment, a limiting groove is provided on the fixture plate 20 , and the probe member 30 is placed in the limiting groove.

[0039] Specifically, the design of the limit slot provides a clear placement for the probe member 30 and limits its horizontal and vertical movement. This limiting effect ensures that the probe member 30 always maintains a stable position during the test and is less likely to shift. This is crucial for ensuring the accuracy and reliability of the test, as shifting of the probe member 30 may cause distortion or error in the test signal. In addition, the design of the limit slot makes it easier to install and remove the probe member 30. The tester only needs to place the probe member 30 in the limit slot to ensure its stable fixation, without the need for additional fixtures or operating steps. This helps to simplify the test process and reduce test time and cost.

[0040] In one embodiment, the fixture plate 20 is connected to the hard disk body 10 via screws.

[0041] Specifically, the screw connection is a very stable connection method. The tight engagement of the threads ensures a firm connection between the fixture plate 20 and the hard disk body 10. This stable connection helps prevent the fixture plate 20 from loosening or separating from the hard disk body 10 during testing or use, thereby ensuring the accuracy and reliability of the test. In addition, the screw connection design allows the fixture plate 20 to be easily assembled and disassembled from the hard disk body 10. When the fixture plate 20 needs to be replaced or adjusted, it can be easily removed by simply loosening the screws, and then the new or adjusted fixture plate 20 can be fixed to the hard disk body 10 with screws. This design improves the flexibility and convenience of the test, allowing testers to work more efficiently. In addition, the screw connection design allows the fixture plate 20 to be connected to hard disk bodies 10 of different sizes and shapes. By adjusting the position and tightening degree of the screws, the close fit between the fixture plate 20 and different hard disk bodies 10 can be ensured, thereby improving the versatility and applicability of the fixture plate 20.

[0042] In one embodiment, the fixture plate 20 is bonded to the surface of the hard disk body 10 .

[0043] Specifically, the bonding technology can firmly fix the fixture plate 20 to the surface of the hard disk body 10, forming a tight bond. This stable connection helps prevent the fixture plate 20 from loosening or separating from the hard disk body 10 during testing or use. This is crucial to ensuring the accuracy and reliability of the test, as any looseness may lead to deviations in the test results. In addition, compared with screw connections, bonding technology does not require drilling or tightening screws, thereby simplifying the installation process. Testers only need to place the fixture plate 20 on the surface of the hard disk body 10 and use an appropriate adhesive to bond it. This simplified installation process not only saves time, but also reduces the difficulty of installation, allowing testers to carry out their work more efficiently.

[0044] In one embodiment, the fixture plate 20 is made of plastic or metal.

[0045] Specifically, the plastic material is generally lighter than metal, which makes the overall weight of the clamp plate 20 lighter, facilitating carrying and operation; the plastic material has good corrosion resistance and can maintain stable performance in harsh environments such as humidity, acid and alkali; plastic is a good insulating material that can prevent current from passing through, ensuring the safety of the testing process; the cost of the plastic material is relatively low, which helps to reduce the overall cost of the clamp plate 20. Among them, the metal material has high strength and hardness, can withstand a large force and pressure, and ensures that the clamp plate 20 does not deform or break during use; the metal material has good wear resistance and is not easy to wear out after long-term use, prolonging the service life of the clamp plate 20. Whether it is a plastic or metal material, the clamp plate 20 can provide stable support for the probe piece 30, ensuring that the position and direction of the probe piece 30 remain unchanged during the testing process, thereby improving the accuracy and reliability of the test.

[0046] Among them, the probe piece 30 adopts the existing disclosed technology, which will not be described in detail here.

[0047] The above embodiment is a preferred implementation scheme of the present application, in addition to this, the present application can also be implemented in other ways, any obvious replacement without departing from the technical scheme concept is within the protection scope of the present application.
