Abstract

The invention discloses an impedance measuring component, an impedance measuring device and an impedance measuring method. The impedance measuring component comprises a pressing rod, a connecting shaft and a first probe, wherein the connecting shaft is connected with one end of the pressing rod; the first probe is fixed on the pressing rod; one end of the first probe is electrically connected with an electrode of an impedometer; when the pressing rod is pressed down, the other end of the first probe is electrically connected with a measuring point of an article to be measured. The impedance measuring device comprises the impedance measuring component. The impedance measuring device is adopted in the impedance measuring method. The difference of impedance of the article to be measured can be reduced, the measurement stability can be improved, and moreover the impedance measuring device is relatively rapid, convenient and flexible to measure, and is relatively wide in applicability.

Description

technical field [0001] The invention relates to the field of impedance measurement in the electronics industry, in particular to an impedance measurement component, an impedance measurement device and an impedance measurement method. Background technique [0002] At present, the impedance measurement on the mobile terminal or the casing of the mobile terminal is performed manually by directly contacting the probe on the ohmmeter or multimeter to the point to be measured. [0003] For the less rigid object to be measured, that is, the material of the object to be measured is soft, the measurement error of impedance will increase due to the difference in the contact area during manual measurement, and at the same time, the pressure applied to the object to be measured is different, making the The impedance of the measurement object itself changes greatly. Therefore, with the traditional impedance measurement method, the impedance values ​​measured by the same person in multip...
