Abstract
In a high-frequency probe having a detachable end according to the present invention, parts relating to replacement of an end unit are three parts, that is, an end unit, a probe body, and a pressure block. The end unit comprises a coaxial cable, two slender plate-like ground plates. The coaxial cable is linear in the direction of the end of the high-frequency probe. The ground plates sandwich the coaxial cable. The probe body has an end unit support surface, a circuit board, an end unit arrangement surface and an end part guide. The end unit support surface forms a perpendicular surface used for fixing the end unit to a predetermined position in the end side of the central block in a central part of a surface of the body block. The circuit board connects the end unit to a coaxial connector. The end unit arrangement surface forms a plane in an end side of the body block. And further the guide groove positions and fixes the ground plate in the end part. It is capable to supply positioning pins and a positioning pin holes in mutual contact surfaces for positioning. The present invention makes it possible to adjust characteristic impedance of the probe end part by providing an elastica…
