PROBE PIN AND INSPECTION DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/141561
Kind Code:
A1
Abstract:
This probe pin comprises an elastic cylindrical body that expands and contracts along the central axis thereof, a conductive first plunger that extends into the interior of the elastic cylindrical body along the central axis from one end of the elastic cylindrical body, and a conductive second plunger that extends into the interior of the elastic cylindrical body along the central axis from the other end of the elastic cylindrical body. The first plunger and the second plunger are connected so as to be able to move relative to one another along the central axis in the interior of the elastic cylindrical body. The first plunger body is provided with: an inclined surface that is tapered from the exterior towards the interior of the elastic cylindrical body, is positioned so as to be able to touch the second plunger body inside the elastic cylindrical body, and is biased in a direction that intersects with the central axis due to the relative movement of the first plunger and the second plunger; and an elastic part that is capable of elastic deformation and that is provided between the inclined surface and the first terminal area.
