Abstract
Abstract A transition piece for establishing a transition between a coaxial cable having an inner conductor and an outer conductor and a plug-in connector component having a plurality of terminals disposed adjacent one another, composed of a coupling member in the form of a coplanar stripline presenting a conductive strip and a conductive surface surrounding, and electrically insulated from, the conductive strip, the coupling member being connected to the coaxial cable and the connector component in such a manner that the inner conductor of the cable is connected to a point at one end of the conductive strip, the outer conductor of the cable is connected to the conductive surface, a first terminal of the connector component is connected to a point at the end of the conductive strip opposite its one end, and at least one terminal adjacent the first terminal is connected to the conductive surface.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
129 words
A transition piece for establishing a transition between a coaxial cable having an inner conductor and an outer conductor and a plug-in connector component having a plurality of terminals disposed adjacent one another, comprising a coupling member in the form of a coplanar stripline presenting a conductive strip and a conductive surface surrounding, and electrically insulated from, said conductive strip, means connecting the inner conductor of the cable to a point at one end of said conductive strip, means connecting the outer conductor of the cable to said conductive surface, means connecting a first terminal of the connector component to a point at the end of said conductive strip opposite its said one end, and means connecting at least one terminal adjacent the first terminal to said conductive surface.
Claim 2
Dependent Claim
129 words
A transition piece for establishing a transition between a coaxial cable having an inner conductor and an outer conductor and a plug-in connector component having a plurality of terminals disposed adjacent one another, comprising a coupling member in the form of a coplanar stripline presenting a conductive strip and a conductive surface surrounding, and electrically insulated from, said conductive strip, means connecting the inner conductor of the cable to a point at one end of said conductive strip, means connecting the outer conductor of the cable to said conductive surface, means connecting a first terminal of the connector component to a point at the end of said conductive strip opposite its said one end, and means connecting at least one terminal adjacent the first terminal to said conductive surface.
Claim 3
Dependent Claim
88 words
A transition piece as defined in claim 1 wherein said means connecting the outer cable conductor connect that outer conductor to said conductive surface at a plurality of spaced points distributed symmetrically about the point of connection of the inner cable conductor to said conductive strip, and said means connecting at least one terminal connect a plurality of terminals adjacent the first terminal to said conductive surface at a plurality of spaced points distributed symmetrically about the point of connection of the first terminal to said conductive strip.
Claim 4
Dependent Claim
78 words
A transition piece as defined in claim 1 or 2 wherein said conductive surface presents a recess within which said conductive strip is disposed and said strip and surface are configured such that, in a direction transverse to the direction between the two ends of said strip, the dimensions of said recess and said strip have a ratio to one another selected for matching the characteristic impedance of the cable to the characteristic impedance of the connector component.
Claim 5
Dependent Claim
73 words
A transition piece as defined in claim 3 wherein said coplanar stripline includes an insulating support on which said strip and surface are disposed and the characteristic impedance of said coplanar stripline is equal to ##EQU3## where ε r =the relative dielectric constant of said support B=said dimension of said recess transverse to the direction between said strip ends; and b=said dimension of said strip transverse to the direction of said strip ends.
