The present invention relates to a rotary signal coupler, that is to say a device for providing signal coupling between two components which are rotatable relative to each other. A coupler is provided comprising a first substantially circular track secured to a first support (not shown) and a second substantially circular track (102) secured to a second support (10) which is rotatable relative to the first support. The first and second tracks are coaxial with the axis of rotation of the rotatable second support (10) and are adjacent each other so as to provide signal coupling therebetween. The second track (102) has at least two gaps (106, 108) therein which form electrical discontinuities between separated track portions. The separated track portions are electrically connected (110) to one another. Signal coupling with a rotatable support having a relatively large diameter may be thereby improved.
A rotary signal coupler comprising:
A rotary signal coupler as claimed in any of the preceding claims, wherein said one of said tracks has two gaps (106, 108) which provide two separated track portions substantially semi-circular in shape.
A rotary signal coupler as claimed in any of the preceding claims, wherein said transmission line (110) comprises a coax cable.
A rotary signal coupler as claimed in any of the preceding claims, wherein said transmission line is electrically connected to one of the separated track portions via one of said terminals.
A rotary signal coupler as claimed in any of the preceding claims, wherein the other of said tracks (116) has at least two gaps therein which form electrical discontinuities between separated track portions, the separated track portions being electrically connected to one another.
A rotary signal coupler substantially as hereinbefore described with reference to the accompanying drawings.
