Claim Text:
1. A probe unit, comprising: a probe housing; an at least sectionally rod-shaped, probe electrode; a supplemental electrode, which surrounds said probe electrode at least sectionally coaxially and is isolated from said probe electrode by an electrical insulation; a first securement means, by means of which said supplemental electrode is secured in said probe housing; a contacting module, which is mountable on a rod-shaped section of said probe electrode arranged in said probe housing, and which has a flexible circuit board having at least one first conductive trace for electrically contacting said probe electrode and at least one second conductive trace for electrically contacting said supplemental electrode; and a second securement means for securing said contacting module on said probe electrode, wherein: said contacting module includes, besides the circuit board, an insulating sleeve and a module housing; said insulating sleeve, an essentially cylindrical, basic body for accommodating a section of said rod-shaped probe electrode and, directed orthogonally to said basic body, a 2-dimensional bearing element, which divides said basic body into a first section and a second section; said circuit board has in an end region a first contact region, in which said first conductive trace terminates, and a second contact region in which said second conductive trace terminates; said first contact region and said second contact region each have a central hole, whose diameter at least equals the outer diameter of said basic body of said insulating sleeve; at least said central holes of said first contact region and said second contact region can be made, by folding over of said circuit board to coincide, so that said first contact region is mountable on said first section of said basic body and said second contact region on said second section of said basic body; and said module housing holds the construction of said bearing element and said control regions of said circuit board together.
