Abstract
The invention relates to UHF radio engineering and can be used for transmitting UHF signals from the fixed to the rotatable part of a multichannel coaxial transmission line. Said invention makes it possible to simplify a structural design, reduce overall dimensions and to extend a working wave range. The inventive multichannel rotatable joint comprises concentrically disposed coaxial lines provided with quarter-wave short-circuit insulators and with matching transitions on the ends thereof which a movably jointed by means of a system of quarter-wave choke gaps. Said short-circuit insulators are based on a plane parallel line in the form of two parallel branches comprising multistage impedance transformers. The embodiment of a multichannel rotatable joint in which the length of the coaxial lines of the fixed and rotatable parts thereof are selected such that they are equal to the odd number of quarter-waves is also disclosed.
Description
Invention field
The present invention relates to hyperfrequency (UHF) radio engineering technology, it can be used in the UHF signal is transferred to rotating part from the standing part of multichannel coaxial transmission line, for example, is applied in the multi-functional body radar (multifunctional volume radar).
Technical background
(Japan Patent: No.62-5521,1987 in the known structure of multichannel rotatable joint; No.62-39841,1987 and No.62-39842,1987), adopted the short concentric segments (surrounding each other) of coaxial line, coaxial line has the quarter-wave short-circuited conducting sleeve in the end, in order to the function that realizes the quarter-wave insulator (referring to " Line for transmission ofcentimeter waves ", be translated from English, G.A.Remez edits, " Soviet Union's radio " publishing house, M.1951,172-184 page or leaf).The rotatable portion of this joint is that quarter-wave chokes slit (chokegaps) system and the bearing that forms in the conductor by coaxial line produces with respect to the rotation of standing part.The Low ESR coaxial line is realized by adopting staged tapering transition body with the coupling that is oriented to perpendicular to the standard coaxial joint of rotating shaft.The major defect of this known structure of multichannel rotatable joint is: compare with standard set-up, owing to the existence of the quarter-wave short circuit insulator that forms on the coaxial line basis causes length oversize, and the working band that causes owing to the cross section that reduces coaxial line significantly and wave impedance is not enough.
Summary of the invention
The objective of the invention is simplified structure, reduce external dimensions and enlarge working band.Based on the following fact, can realize described technique effect: on the basis of plane parallel radial transmission line, form quarter-wave short circuit insulator; The length of the coaxial line sections of the standing part of multichannel rotatable joint and rotating part is chosen to be quarter-wave odd-multiple; Based on strip line, form the matching transition body, wherein, the form of this strip line is two parallel legs, these two parallel legs comprise multistage impedance transformer and arrange in the circumference mode.
Description of drawings
Fig. 1 shows the longitudinal cross-section of triple channel turning joint structure;
Fig. 2 shows the cross section that coincides with the matching transition body plane from the coaxial line to the coaxial fitting.
Embodiment
In illustrated structure, this triple channel turning joint has the system that is made up of three mutual cingens center coaxial lines 1, middle coaxial line 2 and outer, coaxial lines 3, these three coaxial lines have public symmetry axis 4, can realize rotation (this axle also is known as rotating shaft) round this common symmetry axis.
The input coaxial fitting 5 of center coaxial line 1 and output coaxial fitting 6 all are positioned on the rotating shaft, the input coaxial fitting 7 of middle coaxial line 2 and the input coaxial fitting 10 of output coaxial fitting 8 and outer, coaxial line 3 lay respectively on the outer cylinder surface of main body 11,12,13 and 14, to be used for the location of matching transition body.Just as in the prototype, top 15 is that quarter-wave chokes slit 17 in dependence bearing 18 and the coaxial line conductor is realized with respect to the fixing rotation of bottom 16.
As everyone knows, the wave impedance ρ of coaxial line is (referring to " the Reference book on elements of waveguide technique " of A.A.Foldshtane etc., " Soviet Union's radio " publishing house, M.1967, the 92-94 page or leaf) define with relational expression ρ=138lg D/d ohm, wherein D and d are the diameters of coaxial inner conductor and outer conductor.The impedance of standard coaxial joint equals 50 ohm.The dimension D and the d of the conductor of suitable selection center coaxial line 1, so that the wave impedance of this line equals standard value, promptly 50 ohm.
In the process of conductor size D that selects coaxial line 2 and 3 and d, need follow structure and consider, so their wave impedance is about 10 ohm magnitude, will be well below standard value.Therefore, for they can be complementary with the standard coaxial joint, suggestion is used based on strip line 21 and 22 and the matching transition body that forms, described strip line comprises annular solid 23 and the center conductor that is made of two parallel legs 24, and wherein these two parallel legs comprise three grades of impedance transformers 25,26,27.The matching transition body of this form makes the cross section of conductor reduce half, has realized the symmetry that is connected with the coaxial line center conductor, and integrates with the structure of this equipment in the best way.Also have dielectric to insert body 28, it is used for fixing the position of stripline conductors.The structure that can embody described multichannel rotatable joint by production and the technique effect in the assembling process at element.The production technology of some elements and assembly is shown in the given accompanying drawing, and can assemble by means of screw 29 and 30 pairs of assemblies.
The actual realization possibility of the suggestion structure of this multichannel rotatable joint has obtained experimental verification.At working band is 1.0 to 1.6GHz (Δ f
p=± 23%) receive the time: all three-aisled VSWR (voltage standing wave ratio)---all be no more than 1.5; Loss---(0.2-0.5) dB; Decoupling between the adjacency channel---be not less than 20dB; Decoupling between the edge gateway-be not less than 40dB; The index of modulation of parameter in the rotary course---be no more than 1%.The size of equipment---Φ 180 * 180mm; Weight---7.5kg.
