Abstract
Description

[0002] With the advancement of technology, the demand for ESD and TLP testing has exploded. The probes used in traditional TLP testing are all single-probe structures. Because TLP testing requires a loop, the ground wire often needs to be connected to the ground of the device under test from the coaxial cable housing on the basis of the single probe just mentioned. However, the specific disadvantage is that the ground loop is long and the test is unstable, so it is necessary to add another needle holder probe arm, and adding an additional needle holder probe arm will cause more space to be occupied; and each test requires adjusting two needle holders, which reduces the test efficiency. Utility Model Content

[0005] The triangular fixing block is fixedly arranged on the bottom plate of the probe body;
[0006] A signal probe is provided on the triangular fixed block;
[0007] The grounding probe push slider is arranged on the bottom plate of the probe body and is connected to the triangular fixing block through a screw rod;
[0008] The grounding probe is arranged on a side of the grounding probe pushing sliding block close to the signal probe.
[0009] Preferably, a spring is provided between the grounding probe pushing sliding block and the triangular fixing block.
[0010] Preferably, a first spring placement hole is provided at a position of the grounding probe pushing the sliding block corresponding to the spring.
