The utility model content
The technical matters that the utility model mainly solves provides a kind of testing impedance probe, and static is transferred on the test module and influences test module serviceable life in the time of preventing to test syringe needle static is directly delivered on the whole test probe and prevents to test.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of testing impedance probe is provided, comprise a sleeve pipe and a test syringe needle, be provided with a coaxial cable and an insulated spring in the described sleeve pipe, one end of described test syringe needle is plugged in the described sleeve pipe, described insulated spring connects described test syringe needle and described coaxial cable, has an insulating resin layer between described sleeve pipe and the described coaxial cable, described sleeve pipe ground connection.
Wherein, described test syringe needle has syringe needle and the shank that is connected with syringe needle one end, and the other end of described shank has protruded out one first abutment end, and described first abutment end is connected on the end of described insulated spring.
Wherein, described syringe needle axial cross section is triangular in shape.
Wherein, the axial width of the end to end of the shank of described test syringe needle broadens gradually, and described shank is in the axial width of an end of the contiguous insulated spring diameter greater than described insulated spring.
Wherein, the axial width of first abutment end of described test syringe needle is less than the diameter of described insulated spring.
Wherein, described coaxial cable has protruded out second abutment end in an end of contiguous described insulated spring, has a signal wire connection jaws away from an end of insulated spring.
Wherein, the axial width of described second abutment end is less than the diameter of described insulated spring.
The beneficial effects of the utility model are: the test syringe needle that is different from the testing impedance probe of prior art is structure as a whole with sleeve pipe and is connected with metal spring, the test syringe needle static that touches can be delivered on the whole testing needle and during test static can directly be transferred to and influence the test module situation in serviceable life on the test module by metal spring.The utility model testing impedance probe is by testing syringe needle and sleeve pipe is set to isolating construction; one end of test syringe needle is plugged in the described sleeve pipe; and coaxial cable is set in sleeve pipe and is connected the insulated spring of coaxial cable with the test syringe needle; so when the test syringe needle touches thing to be tested; because the insulated barriers of insulated spring makes the static on the thing to be tested flow to ground by the test syringe needle by sleeve pipe; and when the test syringe needle presses down thing compression insulated spring feasible test syringe needle to be tested and coaxial cable continuity test; this moment, test specimen to be measured was led away with the static on the test syringe needle; there is not static; so just can prevent that static directly is transferred to makes the TDR Test module by the situation of electrostatic breakdown on the TDR Test module, play the effect of protecting the TDR Test module.
