Patent ID: 7416443

Claim:
A coaxial coupling comprising a coaxial airline, having a coaxial plug or a coaxial socket for connecting to a coaxial coupling of a device to be calibrated, wherein said coaxial coupling comprises: an inner conductor part and an outer conductor part arranged coaxially therewith, having a short-circuit connection provided between said inner conductor part and said outer conductor part; a contact coupling sleeve provided on which said outer conductor part and said inner conductor part are fixed axially displaceable relative to one another, characterizing said connection; and a contact mechanism arranged and designed such that said contact mechanism optionally acts on said contact coupling sleeve so that the contact coupling sleeve creates said short-circuit connection in the form of a detachable electrical contact between said inner conductor part and said outer contact part, and simultaneously mechanically fixes said inner conductor part and said outer conductor part in their position relative to one another.
