Description

Technical Field

[0001] This utility model relates to the field of probe device technology, and in particular to a high-precision measurement probe device based on adaptive calibration. Background Technology

[0002] In the field of precision measurement, oscilloscope measurement probes play a crucial role. An oscilloscope measurement probe is a key component used to connect an oscilloscope to the circuit under test, enabling the transmission and measurement of electrical signals. It converts voltage or current signals in a circuit into signals that the oscilloscope can recognize, thereby helping engineers and technicians analyze circuit performance, diagnose faults, or conduct scientific research.

[0003] Traditional calibration methods often require using a screwdriver to turn the adjusting screw on the probe connector to adjust the compensation capacitor inside the probe, thereby achieving calibration. However, this method has significant problems. First, although the adjusting screw is located inside the adjusting hole, external dust can easily enter the adjusting hole through tiny gaps and accumulate on the adjusting screw. Long-term accumulation of dust not only accelerates the wear of the adjusting screw, causing it to loosen or become stuck, but also affects the accuracy of the adjustment. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this invention is to propose a high-precision measurement probe device based on adaptive calibration to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a high-precision measurement probe device based on adaptive calibration, comprising a connector body, one end of which is fixedly connected to a wire, and the other end of the wire away from the connector body is fixedly connected to a probe body. A frame is slidably connected to the outer surface of the connector body, and a sealing plate is fixedly connected to one side of the frame. An adjustment hole is provided on one side of the connector body, and the sealing plate corresponds vertically to the adjustment hole. An adjustment screw is threaded into the adjustment hole. Slide grooves are provided on both the left and right sides of the connector body, and a connecting plate is slidably connected to the inner wall of each slide groove. Both connecting plates are fixedly connected to the frame, and a spring is fixedly connected between each connecting plate and the connector body. The two springs are located inside the two slide grooves respectively.

[0007] Preferably, in any of the above solutions, a retaining plate is fixedly connected to the end of the sealing plate away from the frame, and the sealing plate is engaged with the connector body through the retaining plate.

[0008] Preferably, in any of the above embodiments, a transparent glass is embedded in the inner wall of the sealing plate, and an annular scale strip is embedded in one side of the adjustment hole, with the annular scale strip and the adjustment screw corresponding to the transparent glass.

[0009] Preferably, in any of the above solutions, anti-slip pads are fixedly connected to both the left and right sides of the frame, and the anti-slip pads are made of rubber.

[0010] Preferably, one side of the connector body is fixedly connected to a limiting plate, and one side of the frame is provided with a limiting groove. The limiting plate is slidably connected to the frame through the limiting groove.

[0011] Preferably, in any of the above solutions, a guide rod is fixedly connected to the inner wall of each of the grooves, the guide rod is located inside the spring, and the connecting plate is slidably connected to the guide rod.

[0012] Preferably, one side of the frame is fixedly connected to a plurality of symmetrically arranged baffles, and the inner side of the baffles is fixedly connected to a rubber gasket, which is in contact with the connector body.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] When the probe needs to be calibrated, the operator can pull the frame to make the connecting plate slide inside the groove. At this time, the connecting plate will compress the spring. As the spring is compressed, the sealing plate will move with the frame until the adjustment hole is fully exposed. Then, the operator can use a screwdriver to turn the adjustment screw to adjust and calibrate the compensation capacitor inside the probe. After the calibration is completed, the frame is released. The compressed spring will then return to its original position, which will drive the sealing plate to return to its original position until the locking plate is engaged with the connector body. At this time, the sealing plate can seal the adjustment hole to prevent external dust from entering the adjustment hole and prevent dust accumulation from accelerating the wear of the adjustment screw.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0022] like Figures 1 to 5 As shown, a high-precision measurement probe device based on adaptive calibration includes a connector body 1. One end of the connector body 1 is fixedly connected to a wire 2, and the end of the wire 2 away from the connector body 1 is fixedly connected to a probe body 3. A frame 4 is slidably connected to the outer surface of the connector body 1. A sealing plate 5 is fixedly connected to one side of the frame 4. An adjustment hole 6 is opened on one side of the connector body 1. The sealing plate 5 corresponds vertically to the adjustment hole 6. An adjustment screw 7 is threaded inside the adjustment hole 6. Slide grooves 8 are opened on both the left and right sides of the connector body 1. A connecting plate 9 is slidably connected to the inner wall of each slide groove 8. Both connecting plates 9 are fixedly connected to the frame 4. A spring 10 is fixedly connected between each connecting plate 9 and the connector body 1. The two springs 10 are located inside the two slide grooves 8 respectively.

[0023] As an optional technical solution of this utility model, a clamping plate 11 is fixedly connected to the end of the sealing plate 5 away from the frame 4. The sealing plate 5 is clamped to the connector body 1 through the clamping plate 11. The clamping plate 11 and the connector body 1 are clamped together to ensure a stable connection between the sealing plate 5 and the connector body 1, prevent the sealing plate 5 from falling off accidentally during use, and improve the overall stability and reliability of the device.

[0024] As an optional technical solution of this utility model, a transparent glass 12 is embedded in the inner wall of the sealing plate 5, and an annular scale bar 13 is embedded in one side of the adjustment hole 6. The annular scale bar 13 and the adjustment screw 7 are all corresponding to the transparent glass 12, so that the user can clearly observe the position and status of the annular scale bar 13 and the adjustment screw 7, which is convenient for precise calibration and adjustment.

[0025] As an optional technical solution of this utility model, anti-slip pads 14 are fixedly connected to both the left and right sides of the frame 4. The anti-slip pads 14 are made of rubber, and the anti-slip pads 14 increase the friction between the frame 4 and the worker's hands.

[0026] As an optional technical solution of this utility model, a limiting plate 15 is fixedly connected to one side of the connector body 1, and a limiting groove 16 is opened through one side of the frame 4. The limiting plate 15 is slidably connected to the frame 4 through the limiting groove 16. By sliding the limiting plate 15 in the limiting groove 16, the range of movement of the connector body 1 relative to the frame 4 is limited, ensuring the stability and accuracy of the sealing plate 5 during the adjustment process.

[0027] As an optional technical solution of this utility model, a guide rod 17 is fixedly connected to the inner wall of each slide groove 8. The guide rod 17 is located inside the spring 10, and the connecting plate 9 is slidably connected to the guide rod 17. The guide rod 17 provides a stable sliding track for the connecting plate 9, preventing the connecting plate 9 from deviating from the predetermined path during movement, thereby improving the accuracy and stability of adjustment. At the same time, the guide rod 17, located inside the spring 10, can also support and protect the spring 10.

[0028] As an optional technical solution of this utility model, a number of symmetrically arranged baffles 18 are fixedly connected to one side of the frame 4, and rubber gaskets 19 are fixedly connected to the inner side of the baffles 18. The rubber gaskets 19 are in contact with the connector body 1, and the setting of the rubber gaskets 19 can prevent rigid collision between the frame 4 and the connector body 1.

[0029] A high-precision measurement probe device based on adaptive calibration works as follows:

[0030] 1): When the probe device needs to be calibrated, the staff can pull the frame 4 to make the connecting plate 9 slide inside the slide groove 8. At this time, the connecting plate 9 will squeeze the spring 10. As the spring 10 is compressed, the sealing plate 5 will move together with the frame 4.

[0031] 2): After the adjustment hole 6 is fully exposed, the staff can use a screwdriver to turn the adjustment screw 7 to adjust and calibrate the compensation capacitor inside the probe.

[0032] 3): After the calibration is completed, release the frame 4. At this time, the compressed spring 10 will return to its original position, which will drive the sealing plate 5 to return to its original position until the clamping plate 11 is engaged with the connector body 1. At this time, the sealing plate 5 can seal the adjustment hole 6 to prevent external dust from entering the adjustment hole 6.

[0033] In summary, this high-precision measurement probe device based on adaptive calibration allows for calibration when the probe needs to be calibrated. The operator can pull the frame 4 to slide the connecting plate 9 within the groove 8. The connecting plate 9 compresses the spring 10, and as the spring 10 is compressed, the sealing plate 5 moves with the frame 4 until the adjustment hole 6 is fully exposed. The operator can then use a screwdriver to turn the adjusting screw 7 to adjust and calibrate the compensation capacitor inside the probe. After calibration, the frame 4 is released, and the compressed spring 10 returns to its original position, causing the sealing plate 5 to return to its original position until the locking plate 11 engages with the connector body 1. At this point, the sealing plate 5 seals the adjustment hole 6, preventing external dust from entering and accelerating the wear of the adjusting screw. The guide rod 17 provides a stable sliding track for the connecting plate 9, preventing it from deviating from the predetermined path during movement and improving the accuracy and stability of the adjustment. Meanwhile, the guide rod 17 is located inside the spring 10 and can also support and protect the spring 10. By sliding the limiting plate 15 in the limiting groove 16, the range of movement of the connector body 1 relative to the frame 4 is limited, ensuring the stability and accuracy of the sealing plate 5 during the adjustment process.
