Abstract
Abstract A connecting element for waveguides includes two waveguide sections which are contacted with each other via a bent choke of two sections and mechanically connected so as to allow a longitudinal displacement, tilting and rotation relative to each other. One waveguide section is provided at its circumference with an axial annular groove extending radially outside the axial section of the choke and the second waveguide section is provided with a circumferential collar projecting at least in an axial direction and engaging in the annular groove.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
139 words
A connecting element for waveguides, comprising: a first waveguide section; a second waveguide section; and choke means for electrically coupling said first and second waveguides, said first and second waveguide sections being mechanically connectable via said choke means for permitting said waveguide sections to be displaced in an axial direction, to be tilted and to be rotated relative to each other, said choke means including a first section extending between facing connecting planes of said first and second waveguide sections and an axial section provided in one of said waveguide sections, said first waveguide section being provided at its periphery with an axial annular groove extending radially outside said axial section of said choke means, and said second waveguide section being provided with a circumferential collar projecting at least in an axial direction and engaging in said annular groove.
Claim 2
Dependent Claim
139 words
A connecting element for waveguides, comprising: a first waveguide section; a second waveguide section; and choke means for electrically coupling said first and second waveguides, said first and second waveguide sections being mechanically connectable via said choke means for permitting said waveguide sections to be displaced in an axial direction, to be tilted and to be rotated relative to each other, said choke means including a first section extending between facing connecting planes of said first and second waveguide sections and an axial section provided in one of said waveguide sections, said first waveguide section being provided at its periphery with an axial annular groove extending radially outside said axial section of said choke means, and said second waveguide section being provided with a circumferential collar projecting at least in an axial direction and engaging in said annular groove.
Claim 3
Dependent Claim
27 words
A connecting element as defined in claim 1 wherein said collar has an axial length which exceeds the maximum admissible range of displacement between said waveguide sections.
Claim 4
Dependent Claim
39 words
A connecting element as defined in claim 1 wherein said collar has a radial thickness and said annular groove has a radial width, said radial thickness of said collar being smaller than the radial width of said annular groove.
Claim 5
Dependent Claim
37 words
A connecting element as defined in claim 1, and further comprising a guide and safety ring, said first waveguide section extending over said second waveguide section beyond said collar and ending in said guide and safety ring.
Claim 6
Dependent Claim
36 words
A connecting element as defined in claim 1 wherein said first waveguide section extends over said second waveguide section beyond said collar to define a recess therebetween, and further comprising an O-ring disposed in said recess.
Claim 7
Dependent Claim
16 words
A connecting element as defined in claim 5 wherein said O-ring is made of rf-conducting rubber.
Claim 8
Dependent Claim
112 words
A connecting element for waveguides, comprising: a first waveguide section; a second waveguide section; and a choke defined by a gap between facing connecting planes of said first and second waveguide section for electrically coupling the latter, said first and second waveguide sections being mechanically connectable in such a manner that under variation of said gap said waveguide sections are axially displaceable, tiltable and rotatable relative to each other, said first waveguide section being provided at its periphery with an axial annular groove extending radially outside said choke, and said second waveguide section being provided with a circumferential collar projecting at least in an axial direction and engaging in said annular groove.
Claim 9
Dependent Claim
112 words
A connecting element for waveguides, comprising: a first waveguide section; a second waveguide section; and a choke defined by a gap between facing connecting planes of said first and second waveguide section for electrically coupling the latter, said first and second waveguide sections being mechanically connectable in such a manner that under variation of said gap said waveguide sections are axially displaceable, tiltable and rotatable relative to each other, said first waveguide section being provided at its periphery with an axial annular groove extending radially outside said choke, and said second waveguide section being provided with a circumferential collar projecting at least in an axial direction and engaging in said annular groove.
Claim 10
Dependent Claim
50 words
A connecting element as defined in claim 7, wherein said choke includes a first section extending between facing connecting planes of said first and second waveguide sections and an axial section provided in one of said waveguide sections, said axial groove extending radially outside said axial section of said choke.
