Abstract
The disclosure concerns a coaxial h-f multiple rotary connection, in particular for rotating antennas of radar equipment, comprising galvanic rotary contacts. In the rotary coupling of the hollow inner conductors of an outer coaxial system the rotary coupling of an inner coaxial system forming for said outer system only a reactance is disposed and the outer conductors of the inner coaxial system led radially out of the outer coaxial system are connected to the outer conductors of the outer coaxial system. This reactance can be compensated by suitable dimensioning, ensuring reflexion-free passage of the outer line.
Claims5
A rotary assembly of HF coaxial cables, with a portion of one of the cables being inside the other of the cables, comprising;
- an internal coaxial cable having a first internal conductor and a first external conductor outside said first internal conductor;
- said internal cable having a first portion of a first length and said first portion being inside an external coaxial cable;
- an external coaxial cable having a hollow second internal conductor;
- said second internal conductor having a second portion of at least said first length and said second portion having a cross section greater than the cross section of said first external conductor;
- said external cable having a second external conductor outside said second internal conductor;
- said internal cable first portion being located inside said second internal conductor second portion;
- beyond both ends of its said first portion, said internal cable passing from within said second internal conductor through both said second internal and external conductors to without said external cable, whereby said internal cable serves as a reactance in said external cable;
- said first external conductor being electrically connected to said second external conductor at both locations along said internal cable where said internal cable passes through said second external conductor;
- said internal cable first portion being separated into two sections, first rotary coupling means separably joining both of said internal cable first and second conductors in said internal cable first portion;
- said external cable second portion being separated into two sections, second rotary coupling means separably joining both of said external cable second internal and external conductors in said external cable second portion.
