Abstract:
An air interface apparatus that operates as a signal transmission carrier between an object under test and a probe device when testing the object under test by using the probe device, which comprises:inner conductive means which has a long hollow cylindrical shape and whose both ends are open; outer conductive means whose both ends are open and which surrounds the inner conductive means with a constant gap and has a long cylindrical shape; a first signal pin being contacted to the object under test and inserted into and projected from one end of the inner conductive means; a second signal pin being contacted to the probe device and inserted into and projected from the other end of the inner conductive means; elastic means for supporting the first and the second signal pins within the inner conductive means to make the first and the second signal pins move in and out from both ends of the inner conductive means, respectively, by the elastic force of the elastic means in response to external pressure; and insulating means for insulating the inner conductive means from the outer conductive means, locating between the inner conductive means and the outer conductive means at both ends of the outer conductive means to thereby make the inner and the outer conductive means support each other.
