Problems solved by technology

However, this impedance probe device can only adjust the distance between the two probe heads. If the thickness of the circuit board to be detected is inconsistent, it is difficult to adjust the distance between the two probe heads and the circuit board, which will affect the probe device. The test results

Abstract

The invention discloses a probe device for impedance detection. The probe device comprises a chassis; a first fixing structure and a second fixing structure vertical to the chassis; at least one first probe assembly and at least one second probe assembly which are respectively arranged on the end part of the first fixing structure and the end part of the second fixing structure, wherein the second probe assembly and the first probe assembly are opposite to each other in one-to-one correspondence and are used for detecting the impedance of a circuit board in a matched manner, the first fixing structure is fixed on the chassis, and the second fixing structure is movably arranged on the chassis through a driving device; and at least two first lifting devices used for respectively driving the first probe assembly and the second probe assembly to move up and down so as to adjust the heights of the first probe assembly and the second probe assembly anytime according to the thickness of a circuit board when the impedance detection is carried out on circuit boards different in thickness. In this way, the first probe assembly and the second probe assembly are enabled to contact the surface of the circuit board, and impedance detection on the circuit board is completed under the cooperation of the two probe assemblies.

Description

technical field [0001] The invention relates to the technical field of circuit board impedance detection, in particular to a probe device for impedance detection. Background technique [0002] In the prior art, after the circuit with the desired shape is prepared on the circuit board, it is necessary to use an impedance detection probe to detect the circuit on the circuit board, and judge whether the circuit on the circuit board meets the requirements based on the detection result. [0003] Chinese patent document CN203385768U discloses a circuit board impedance detection probe device, including a housing with an opening facing upwards, an upper cover arranged on the opening of the housing; two probe assemblies arranged in the housing, the probe assembly includes a cable, and the Probe heads and connection terminals at both ends of the cable, the end of the probe head away from the end of the cable is located outside the housing, and the connection terminals are located outs...
