HF coaxial plug connector

Claim 2

An HF coaxial conductor clamping assembly comprising: a coaxial cable with an internal conductor, an external conductor surrounding said internal conductor and a dielectric layer therebetween; a clamping ring extending annularly around said external conductor and having an end with an end face over which said external conductor is crimped; an annular plug connector positioned in opposed relationship to said clamping ring end; said plug connector having an end contact annular surface positioned such that said clamping ring end face clamps said external conductor against said annular surface for making electric contact; a nut having a shoulder facing toward said plug connector annular surface; said clamping ring being between said nut shoulder and said end contact annular surface and said shoulder being spaced from said clamping ring; means on said nut for screwing it onto said plug connector and for tightening said nut toward said plug connector end contact annular surface; a pressure transmitting sleeve extending annularly around said external conductor and interposed between said clamping ring and said nut shoulder, such that tightening of said nut presses said sleeve against said clamping ring to clamp said external conductor; said sleeve and said clamping ring having cooperating, engaging and matingly tapered annuLar surfaces that are angled to force said clamping ring radially inwardly against said external conductor.

Claim 3

The assembly of claim 1, further comprising: said plug connector end annular surface having a radially inner end adjacent to said external conductor and which is conically shaped to define a second shoulder; said external conductor crimped part and said clamping ring end face are rounded, thereby to cooperatively engage said second shoulder.

Claim 4

The assembly of claim 2, wherein said clamping ring has a sleeve part extending along said cable and toward said nut; an insulating layer located outside of and extending around said external conductor; said sleeve part of said clamping ring extending between said insulating layer and said external conductor.

Claim 5

The assembly of claim 3, wherein said pressure transmitting sleeve has an interior side facing toward said insulating layer; said pressure transmitting sleeve interior side having an interior annular groove formed therein; an interior sealing ring in said interior annular groove for sealing said pressure transmitting sleeve against said insulating layer; said sleeve part having an exterior surface with a radially outwardly projecting collar thereon, and that said collar is so positioned as to engage said insulating layer at the side of said interior sealing ring that is closer to said nut.

Claim 6

The assembly of claim 1, wherein said pressure transmitting sleeve has an interior side facing toward said cable; said pressure transmitting sleeve interior side having an interior annular groove formed therein; an interior sealing ring in said interior annular groove for sealing said pressure transmitting sleeve against said cable.

Claim 7

The assembly of claim 5, wherein said pressure transmitting sleeve has an exterior side and in said pressure transmitting sleeve exterior side is formed an exterior annular groove; an exterior sealing ring in said exterior annular groove for sealing said pressure transmitting sleeve against said plug connector.

Claim 8

An HF coaxial conductor clamping assembly comprising: a coaxial cable with an internal conductor, an external conductor surrounding said internal conductor and a dielectric layer therebetween; a clamping ring extending annularly around said external conductor and having an end with an end face over which said external conductor is crimped; an annular plug connector positioned in opposed relationship to said clamping ring end; said plug connector having an end contact annular surface positioned such that said clamping ring end face clamps said external conductor against said annular surface for making electric contact; a nut having a shoulder facing toward said plug connector annular surface; said clamping ring being between said nut shoulder and said end contact annular surface and said shoulder being spaced from said clamping ring; means on said nut for screwing it onto said plug connector and for tightening said nut toward said plug connector end contact annular surface; a pressure transmitting sleeve extending annularly around said external conductor and interposed between said clamping ring and said nut shoulder, such that tightening of said nut presses said sleeve against said clamping ring to clamp said external conductor; said sleeve and said clamping ring having cooperating, engaging and annular surfaces; said clamping ring extending annularly around said external conductor and also wraps around that end of said external conductor where it is crimped over said clamping ring; said clamping ring being curvedly shaped to extend away from said nut and toward said plug connector such that said clamping ring has a C-shaped cross-section, with the end of said external conductor extending into the curve of said C-shape; an intermediate ring, annularly extending around said external conductor and having an L-shaped cross-section, with one leg of the L extending into the curve of said C-shape; said intermediate rIng one leg having one surface lying against the crimped over end of said external conductor and having an opposite surface to said one surface that lies against said clamping ring; said intermediate ring also serving as part of said plug connector in that said plug connector end contact annular surface is part of said intermediate ring and said intermediate ring L-shape having another leg on which that said surface is included.

Claim 9

An HF coaxial conductor clamping assembly comprising: a coaxial cable with an internal conductor, an external conductor surrounding said internal conductor and a dielectric layer therebetween; a clamping ring extending annularly around said external conductor and having an end with an end face over which said external conductor is crimped; an annular plug connector positioned in opposed relationship to said clamping ring end; said plug connector having an end contact annular surface positioned such that said clamping ring end face clamps said external conductor against said annular surface for making electric contact; a nut having a shoulder facing toward said plug connector annular surface; said clamping ring being between said nut shoulder and said end contact annular surface and said shoulder being spaced from said clamping ring; means on said nut for screwing it onto said plug connector and for tightening said nut toward said plug connector end contact annular surface; a pressure transmitting sleeve extending annularly around said external conductor and interposed between said clamping ring and said nut shoulder, such that tightening of said nut presses said sleeve against said clamping ring to clamp said external conductor; said sleeve and said clamping ring having cooperating, engaging and annular surfaces; said clamping ring extending annularly around said external conductor and also wraps around that end of said external conductor where it is crimped over said clamping ring; said clamping ring being curvedly shaped to extend away from said nut and toward said plug connector such that said clamping ring has a C-shaped cross-section, with the end of said external conductor extending into the curve of said C-shape; an intermediate ring, annularly extending around said external conductor and having an L-shaped cross-section, with one leg of the L extending into the curve of said C-shape; said intermediate rIng one leg having one surface lying against the crimped over end of said external conductor and having an opposite surface to said one surface that lies against said clamping ring; said intermediate ring also serving as part of said plug connector in that said plug connector end contact annular surface is part of said intermediate ring and said intermediate ring L-shape having another leg on which that said surface is included.

Claim 10

The assembly of claim 7, wherein said intermediate ring L-shape has an inner side inside the L and an outer side outside the L; said clamping ring being crimped over said outer side of said intermediate ring and over the bend of the L-shape of that said ring, in order to connect said clamping ring and said intermediate ring together.
