Description

Technical Field

[0001] The utility model relates to the technical field of oscilloscope probes, and particularly relates to an oscilloscope probe. Background Technique

[0002] An oscilloscope probe is an electronic component connecting the circuit under test and the input end of the oscilloscope, which plays a crucial role in the accuracy and correctness of the measurement result. Essentially, it establishes a physical and electronic connection between the test point or signal source and the oscilloscope. The common structure of an oscilloscope probe generally includes a probe, a ground clip, etc. When detecting the voltage of a circuit board, the probe needs to contact a specific test point on the circuit board to obtain the voltage signal. However, during the detection process, it is easy to apply too much force, resulting in wear of the probe. At the same time, when moving, the probe is easy to hit hard objects and wear, which has certain deficiencies. Therefore, we propose an oscilloscope probe. Content of the Utility Model

[0003] The utility model aims to solve the problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by the utility model is as follows: an oscilloscope probe, including a probe body, a grounding member, a moving tube, an anti-wear component, and a length adjustment component. The probe body includes a probe rod provided and a probe arranged at the top of the probe rod. The grounding member is arranged on the probe rod. The moving tube is inserted outside the probe rod. The anti-wear component includes a screw arranged at the bottom of the probe rod and passing through the moving tube, a nut threadedly connected with the screw and abutting against the moving tube, a first fixing ring bonded to the bottom of the probe rod, a spring welded to the bottom of the first fixing ring, and a second fixing ring welded to the bottom of the spring and bonded to the top end of the moving tube. The length adjustment component includes an adjustment tube inserted outside the moving tube and a fastening knob threadedly connected with the adjustment tube.

[0005] Preferably, a plurality of first positioning grooves are formed on the probe rod, and the cross-sections of the plurality of first positioning grooves are all circular.

[0006] Preferably, the grounding member includes a wire electrically connected to the probe body and a ground clip arranged on the wire.

[0007] Preferably, an installation hole and a second positioning groove are formed on the moving tube, and the second positioning groove has the same structure as the first positioning groove.

[0008] Preferably, a first positioning post is arranged at the top of the first fixing ring, and the first positioning post is inserted into the first positioning groove on the probe rod.

[0009] Preferably, a second positioning post is provided at the bottom of the second fixing ring, and the second positioning post is inserted into a second positioning groove on the moving tube.

[0010] By adopting the above technical solutions, the beneficial effects achieved by the present utility model are as follows: By providing an anti-wear component, without affecting the use of the oscilloscope probe, the wear of the probe caused by hitting hard objects is avoided, and it is detachable for replacing the anti-wear component. At the same time, by providing a length adjustment component, the length of the probe body can be adjusted for long-distance detection, with a large range of use. During use, the spring of the anti-wear component has a certain elasticity, so that there is a buffering effect between the moving tube and the probe body, avoiding the wear of the probe caused by hitting hard objects. The nut can be rotated until the nut completely disengages from the screw rod. After disengagement, the first fixing ring can be directly separated from the probe rod, and the second fixing ring can be separated from the moving tube. After separation, the moving tube and the spring can be moved downward in sequence to disassemble the spring for replacing and repairing the spring. Then, the fastening knob of the length adjustment component can be loosened. After loosening, the adjustment tube can be moved up and down, and the overall length can be changed during movement. After adjusting to an appropriate length, the fastening knob is tightened for long-distance detection, with a large range of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Embodiment 1:

[0025] Refer to Figures 1-5 , which is the first embodiment of the present utility model. This embodiment provides an oscilloscope probe, including a probe body 100, a grounding member 200, a moving tube 300, an anti-wear component 400 and a length adjustment component 500.

[0026] Specifically, the probe body 100 includes a probe rod 101 provided thereon and a probe 102 provided at the top of the probe rod 101. A plurality of first positioning grooves 103 are formed on the probe rod 101. The cross-sections of the plurality of first positioning grooves 103 are all circular. When in use, the probe 102 obtains a voltage signal by contacting a specific test point on the circuit board so as to detect the voltage.

[0027] Specifically, the grounding member 200 is disposed on the probe rod 101. The grounding member 200 includes a wire 202 electrically connected to the probe body 100 and a grounding clip 201 provided on the wire 202. When in use, the grounding clip 201 has a grounding function. While contacting the signal to be measured, the grounding member 200 can connect the stray power supply in the circuit and the ground wire together, thereby forming a stable reference level, so that the signal to be measured can be more accurately displayed on the oscilloscope.

[0028] Specifically, the moving tube 300 is inserted outside the probe rod 101. An installation hole 301 and a second positioning groove 302 are formed on the moving tube 300. The second positioning groove 302 has the same structure as the first positioning groove 103. When in use, the moving tube 300 can move on the probe rod 101. Moving the probe body 100 through the moving tube 300 facilitates buffering the probe 102.

[0029] Specifically, the anti-wear component 400 includes a screw 401 disposed at the bottom of the probe rod 101 and passing through the moving tube 300, a nut 402 threadedly connected to the screw 401 and abutting against the moving tube 300, a first fixing ring 403 bonded to the bottom of the probe rod 101, a spring 405 welded to the bottom of the first fixing ring 403, and a second fixing ring 406 welded to the bottom of the spring 405 and bonded to the top end of the moving tube 300. During use, the spring 405 has a certain elasticity, so that there is a buffering effect between the moving tube 300 and the probe body 100, avoiding wear of the probe 102 caused by hitting hard objects. Moreover, the nut 402 can be rotated until the nut 402 is completely separated from the screw 401. After separation, the first fixing ring 403 can be directly separated from the probe rod 101, and the second fixing ring 406 can be separated from the moving tube 300. After separation, the moving tube 300 and the spring 405 can be moved downward in sequence, and the spring 405 can be disassembled to facilitate the replacement and repair of the spring 405.

[0030] Specifically, the length adjustment component 500 includes an adjustment tube 501 inserted outside the moving tube 300 and a fastening knob 502 threadedly connected to the adjustment tube 501. During use, the fastening knob 502 can be loosened. After the fastening knob 502 is loosened, the adjustment tube 501 can be moved up and down.

Different from the first embodiment, a first positioning post 404 is provided at the top of the first fixing ring 403, and the first positioning post 404 is inserted into the first positioning groove 103 on the probe rod 101. At the same time, a second positioning post 407 is provided at the bottom of the second fixing ring 406, and the second positioning post 407 is inserted into the second positioning groove 302 on the moving tube 300. During use, the cooperation between the first positioning post 404 and the first positioning groove 103 can prevent the first fixing ring 403 from loosening, and the cooperation between the second positioning post 407 and the second positioning groove 302 can prevent the second fixing ring 406 from loosening, extending the service life of the anti-wear component 400.

[0033] Working principle and usage process of the present utility model: During use, the spring 405 of the anti-wear component 400 has a certain elasticity, so that there is a buffering effect between the moving tube 300 and the probe body 100, avoiding the wear of the probe 102 caused by hitting hard objects. And the rotatable nut 402 can be rotated until the nut 402 completely disengages from the screw 401. After disengagement, the first fixing ring 403 can be directly separated from the probe rod 101 and the second fixing ring 406 can be separated from the moving tube 300. After separation, the moving tube 300 and the spring 405 can be moved downward in sequence, and the spring 405 can be disassembled to facilitate the replacement and repair of the spring 405. Then, the fastening knob 502 of the length adjustment component 500 can be loosened. After the fastening knob 502 is loosened, the adjustment tube 501 can be moved up and down. When the adjustment tube 501 moves, the overall length can be changed. After adjusting to the appropriate length, the fastening knob 502 is tightened for long-distance detection with a large range of use.
