Description
Technical Field
[0001] This utility model relates to the field of power supply ripple detection technology, and in particular to a ripple probe structure and oscilloscope. Background Technology
[0002] Traditional oscilloscope probes with external ripple probe structures are mostly integrated spring probe structures. Their spring diameter, spring probe length, horizontal distance between the spring probe and the spring, and the angle between the spring probe and the spring are all fixed. During testing, a corresponding oscilloscope probe needs to be fitted. Furthermore, because of its relatively fixed structure, the actual position adjustment flexibility of the probe is poor. Therefore, it suffers from several problems during use, such as: the fixed spring probe length leading to inconsistent probe lengths when fitted to different oscilloscope probes, resulting in poor contact with the device under test; the fixed horizontal distance between the spring probe and the spring preventing the measurement of small capacitors; and the fixed angle between the spring probe and the spring preventing optimal contact with the device under test. This invention proposes a ripple probe structure to solve the problem of the difficulty in flexibly adjusting the probe position during the use of traditional oscilloscope ripple probes. Utility Model Content

[0035] Traditional oscilloscope external probe structures are mostly one-piece spring probe structures with fixed spring diameter, spring probe length, horizontal distance between the spring probe and the spring, and angle between the spring probe and the spring. During testing, a corresponding oscilloscope probe needs to be fitted. Furthermore, because of its relatively fixed structure, the actual position adjustment flexibility of the probe is poor. Therefore, it suffers from several problems during use, such as: the fixed spring probe length leading to inconsistent probe lengths when fitted to different oscilloscope probes, resulting in poor contact with the device under test; the fixed horizontal distance between the spring probe and the spring preventing the measurement of small capacitors; and the fixed angle between the spring probe and the spring preventing optimal contact with the device under test. This invention proposes a corrugated probe structure to solve the problem of the difficulty in flexibly adjusting the probe position during the use of traditional oscilloscope probes.
[0036] This utility model proposes a corrugated probe structure 100 to solve the above problems.
[0037] Please see Figures 1 to 3In one embodiment of this utility model, the traditional spring probe structure is replaced with an adjustable probe 3 mounting structure. In practical use, the entire corrugated probe structure 100 can be mounted on different types of oscilloscope probes, and the position of the probe 3 can be adjusted according to actual usage requirements. This allows one probe 3 mounting structure to fulfill various testing needs. Compared to the relatively fixed structure of the traditional spring probe, it avoids the frequent replacement of corresponding spring probes during testing, effectively improving the convenience of the testing process. Specifically, the corrugated probe structure 100 includes a mounting component 1 and a fixing and adjusting structure 2. The mounting component 1 is the fixed mounting structure for the entire corrugated probe, forming a fixed connection with the oscilloscope probe during use. It should be noted that the fixing component proposed in this solution is universal and can be used to fix oscilloscope probes of different sizes, avoiding the need to purchase specific models of spring probes for adaptation when the oscilloscope probe type changes. After the entire corrugated probe structure 100 is fixedly connected to the metal connecting part on the outer peripheral wall of the oscilloscope probe end through the mounting part 1, the actual positional correspondence between the probe 3 and the oscilloscope probe can be adjusted according to the actual situation to meet different testing needs. Specifically, a through groove 211 is provided on the fixing part along the first direction. The through groove 211 has a certain length along the first direction, allowing the probe 3 to be set in an inclined position within the through groove 211. The through direction of the through groove 211 corresponds to the axial direction of the oscilloscope probe. When the probe 3 is actually fixedly installed, it needs to be inserted into the through groove 211. According to the actual testing requirements, the position of the test end of the probe 3 is adjusted, that is, the actual length of the probe 3 is adjusted. Then it is determined whether the corresponding test angle needs to be adjusted. When the test angle needs to be adjusted, the probe 3 can be rotated a certain angle within the through groove 211, thereby forming a certain angle relationship between the probe 3 and the oscilloscope probe to meet the adaptability of the test angle. After adjustment, the movement of the abutment 22 is adjusted so that one end of the abutment 22 inside the through groove 211 contacts and presses down on the probe 3, thereby fixing the probe 3 in its current position within the through groove 211. After fixing, testing can be performed by handheld oscilloscope probe. It should be noted that the entire probe structure 100 is an extension of a traditional corrugated probe, so the relevant connecting parts should have basic electrical connection characteristics, including the aforementioned fixing part and mounting part 1. During actual installation, the mounting part 1 is fitted onto the metal connecting part on the outer peripheral wall of the oscilloscope probe end, thus establishing a conductive connection with the oscilloscope probe. In actual operation, measurements are performed by cooperating between the probe 3 on the corrugated probe structure 100 and the grounding terminal on the oscilloscope probe.
[0038] In this embodiment, the fixing part is specifically configured as a shaft component 21, one end of which is fixedly connected to the fixing part. In actual production, part of the structure of the fixing part can be integrally manufactured with the shaft component 21, thereby improving the connection performance between the two. The through groove 211 is specifically configured as a strip groove, the length direction of which corresponds to the first direction. The movement direction of the corresponding abutment 22 is set along the width direction of the through groove 211. When one end of the abutment 22 moves along the width direction of the through groove 211 inside the through groove 211, it can realize the abutment, fixation, and release of the probe 3 inside the through groove 211. It is conceivable that the fixing part does not necessarily have to be configured as the above-mentioned shaft shape. It can also be configured as a square shaft or an irregular shaft structure, and a corresponding through groove 211 can be opened on the corresponding main structure to achieve the above structural functions. In this solution, the fixing part is configured as a circular shaft structure, mainly considering the smooth transition of the external features of the main structure, which can improve the comfort of operation in actual operation.
[0039] After the probe 3 is fixed in the through groove 211 by the abutment member 22, the stability of the position of the abutment member 22 in the axial direction must be ensured to guarantee the fixing effect of the abutment member 22 on the probe 3. Considering the above problems and the convenience of operation, in this embodiment, the abutment member 22 is set as a first threaded member 221 and a pressure plate member 222. Specifically, the first threaded member 221 is installed on a portion of the shaft member 21 structure on one side of the long side of the through groove 211 along the width direction of the through groove 211. One end of the first threaded member 221 corresponding to the inside of the through groove 211 is rotatably connected to the pressure plate member 222. The first threaded member 221 is threadedly engaged with the shaft member 21. In the actual rotation of the first threaded member 221, the first threaded member 221 can move along its axial direction, thereby driving the pressure plate member 222 to move towards or away from the probe 3. Meanwhile, it is conceivable that the threaded installation structure of the first threaded component 221 has a certain self-locking property. When the first threaded component 221 is not subjected to external force, it can ensure the stability of its axial position, that is, the fixing effect can be guaranteed after the fixing is completed. In addition to the aforementioned structures, the abutment component 22 can also be configured as a traditional abutment structure combining a shaft and a snap-fit. However, in the specific operation process, this structure still involves the fixing and contact of the snap-fit component, so it is slightly inferior in terms of operational convenience. Furthermore, it should be noted that in this embodiment, the through groove 211 is configured as a strip groove. During the actual movement of the pressure plate component 222, the two inner sidewalls of the through groove 211 can guide and limit the pressure plate component 222, thereby minimizing the need to set up corresponding guiding structures to guide the installation of the pressure plate component 222.
[0040] Considering that the probe 3 is fixed by a hard contact when the inner wall of the through groove 211 and the pressure plate 222 press down, and the outer wall of the probe 3 is curved, the contact area during fixing is small. However, in actual testing, a contact measurement method is used, so the probe 3 may change position when subjected to force. To avoid the above problems, in this embodiment, a flexible pad 212 is provided on the inner wall of the through groove 211 corresponding to the pressure plate 222 and fixed thereto. During the application of force by the pressure plate 222, the probe 3 can move towards the flexible pad 212, thereby maximizing the fixed contact area of the probe 3 during the fixing process and ensuring the stability of its fixed state during testing. It is conceivable that the upper end of the probe 3 can be designed as a flat design to increase the contact area and also to better fix it.
[0041] As described above, mounting component 1 is a versatile fixing structure that can accommodate oscilloscope probes of different diameters. In this embodiment, mounting component 1 specifically includes a flexible ring 11 and a second threaded component 12. The flexible ring 11 has a certain degree of plasticity, and its inner ring diameter can be set to be slightly larger than the diameter of commonly available oscilloscope probes. In actual installation, the flexible ring 11 is first fitted onto the test end of the oscilloscope probe. Then, the second threaded component 12 is screwed from the outside of the flexible ring 11, so that one end of the second threaded component 12 abuts against the side wall of the oscilloscope probe. The second threaded component 12 is then continued to be screwed, increasing the force between the end of the second threaded component 12 and the oscilloscope probe. At this time, the minimum ring size of the flexible ring 11 is correspondingly reduced, ultimately fixing the oscilloscope probe between the second threaded component 12 and the flexible ring 11. Through this fixing method, the adaptable installation of oscilloscope probes of different diameters can be achieved by adjusting the movement distance of the threaded component along its axial direction. It is also conceivable that the design of the second threaded component 12 and the first threaded component 221 are both intended to improve the convenience of operation through the self-locking property of the threaded engagement; further details will not be elaborated here. Both of the aforementioned threaded components can be configured as screw structures, with a corresponding knob at one end, thereby enhancing the convenience of operation.
[0042] The actual fixing effect of the mounting component 1 needs to be achieved by one end of the second threaded component 12 and the inner wall of the flexible ring 11. Considering that the outer wall of the flexible ring 11 is also provided with the shaft component 21, in order to enable the shaft component 21 to be set along the radial direction of the flexible ring 11, thereby ensuring the accuracy and convenience of the probe 3 position adjustment process, in this embodiment, the shaft component 21 and the second threaded component 12 are set on the same axis. During the adjustment and fixing process of the second threaded component 12, one of the deformation directions of the flexible ring 11 can correspond to the axis that is commonly corresponding to the second threaded component 12 and the shaft component 21. At this time, the installation position of the shaft component 21 can provide better support for the flexible ring 11, and the deformation of the flexible ring 11 will not affect the actual position of the shaft component 21, and the impact on the actual position of the probe 3 is also relatively small.
[0043] To enhance the fixing effect of the flexible ring 11, in this embodiment, a first anti-slip pad 111 is provided on one end of the second threaded component 12 corresponding to the inner side of the flexible ring 11. Simultaneously, a second anti-slip pad 121 can be provided on the inner side of the flexible ring 11 corresponding to the end of the shaft component 21. During actual fixing, the first and second anti-slip pads 121 increase the contact effect, thereby ensuring the fixing effect of the flexible ring 11. Furthermore, to ensure the strength of the flexible ring 11, it is preferable to set the flexible ring 11 as a metal ring. It should be noted that the entire corrugated probe structure 100 is an extension structure of a traditional oscilloscope probe, so it should possess the most basic electrical connection function. The corresponding shaft component 21 is also made of metal. To improve its conductivity, a coating treatment can be applied to the corresponding structural component.
[0044] It should be noted that this solution is applied to the oscilloscope probe structure. In the application process, it has the technical effects described above and can effectively improve the convenience of using the oscilloscope. Therefore, this solution discloses an oscilloscope, specifically including the above-mentioned corrugated probe structure 100, which has all the advantages of the corrugated probe structure 100, which will not be elaborated here.
[0045] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
