Description

Technical Field

[0001] The utility model relates to the field of electronic product signal testing, in particular to an oscilloscope probe connector. Background Art

[0002] As the core component of large computer systems, servers undertake important tasks such as storage, computing, and data transmission. Their stability and reliability are crucial to the operation of the entire system.

[0003] Currently, using an oscilloscope to perform waveform testing is the most common method for evaluating signal quality. The signal is mainly introduced into the oscilloscope through a probe to test the signal waveform amplitude, edge, and burr. By testing the waveform parameters, it can be seen whether the amplitude, edge time, etc. meet the device interface level requirements. The signal test measurement points involve the front and back of the PCA, the number of test signals or voltages is more than 200, and the number of tests exceeds 1,000. It is necessary to ensure that the probe is close to the ground position to ensure a more accurate waveform diagram.

[0004] When using an oscilloscope to perform waveform testing using a grounded alligator clip, it can only be fixed at a larger ground position, and grounding the alligator clip will create a relatively large ground loop. At higher frequencies, there will be obvious parasitic inductance, and the probe itself has a certain input capacitance, so an RLC resonant circuit will be formed. When testing fast-edge signals, interfering waveforms such as ringing are likely to occur, resulting in inaccurate test results. Utility Model Content

[0012] The utility model provides an oscilloscope probe connector, wherein the placement box is used to place the connector body and limit the connector body to prevent the connector body from moving in the placement box and knocking off the grounding spring when the user carries the connector body. The connector body inserts the grounding spring into the grounding part of the oscilloscope probe, and the right end of the second copper tube is inserted into the wire for grounding, so that the grounding part of the oscilloscope probe is connected to the grounding point near the measuring point through the jack type, and the ground ring formed during measurement is reduced, thereby improving the measurement accuracy.
