Abstract
Abstract A coaxial support for an interior conductor includes at least four thin dielectric plates (d) mechanically preformed and which are seated in slits of an exterior conductor element (n), and automatically center and immobilize an interior conductor element of reduced section (i). The support, which has a relatively significant length with respect to the diameter of the exterior conductor, has great rigidity in the transverse and longitudinal directions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
97 words
A mechanically rigid support of an interior conductor for high frequency and microwave coaxial lines and connectors, characterized by the fact that it includes an exterior conductor element (n) having symmetry of revolution and at least four slits, and an interior conductor (i) of reduced section to maintain a constant characteristic impedance over the length of the support, the interior conductor being automatically centered and immobilized longitudinally by at least four small elastic dielectric plates (d) preformed in convex shape with respect to the median axis and introduced in the slits of the exterior conductor element (n).
Claim 2
Dependent Claim
97 words
A mechanically rigid support of an interior conductor for high frequency and microwave coaxial lines and connectors, characterized by the fact that it includes an exterior conductor element (n) having symmetry of revolution and at least four slits, and an interior conductor (i) of reduced section to maintain a constant characteristic impedance over the length of the support, the interior conductor being automatically centered and immobilized longitudinally by at least four small elastic dielectric plates (d) preformed in convex shape with respect to the median axis and introduced in the slits of the exterior conductor element (n).
Claim 3
Dependent Claim
33 words
A support according to claim 1, characterized by the fact that the exterior conductor element (n) has an interior diameter (D 1 ) which is reduced with respect to the joining coaxial line.
Claim 4
Dependent Claim
30 words
A support according to either one of claims 1 and 2, characterized by the fact that the interior conductor (i) has a circular section in its region of reduced section.
Claim 5
Dependent Claim
32 words
A support according to either one of claims 1 and 2, characterized by the fact that the interior conductor (i) has a polygonal section, particularly square, in its region of reduced section.
