Title:
PROBE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/017737
Kind Code:
A1
Abstract:
This invention provides a probe device that can be made to be significantly more compact than the prior art. This probe device comprises an input cable that is connected to a probe terminal, an output terminal that is connected to a prescribed measurement device, and a relay box that reduces a voltage input via the probe terminal to a prescribed voltage level and then outputs the voltage from the output terminal to the measurement device. The relay box comprises: one case; another case; a circuit board that is disposed between the one case and other case, has a plurality of slits formed thereon, and has a plurality of resistance elements placed thereon in a wave shape so as to pass through the plurality of slits; and an insertion rib group comprising a plurality of ribs that are provided on the one case, the other case, or an intermediate member between the one case and other case and are respectively inserted into the plurality of slits on the circuit board so as to maintain a spatial distance between the plurality of resistance elements.
