Abstract
A waveguide port radio frequency coaxial cable component can realize connection of different waveguide ports or reliable connection of a waveguide port with a radio frequency coaxial port and is suitable for microwave systems with a waveguide port connection. The cable component comprises a terminating waveguide port connector and a radio frequency coaxial cable. The end of the cable component is designed as a standard waveguide port matched with a system. When the cable component is used, a user can directly connect the waveguide port of the cable component with a system waveguide port, so that the cable component is convenient to use. Due to the fact that the coaxial cable is bendable and can satisfy the requirements of optional lengths, connection between waveguide ports at optional positions can be realized. Compared with the original manner that the radio frequency coaxial cable component is matched with a waveguide coaxial converter, part number introduced to the system is reduced, two port sections with discontinuous impedance are omitted, system performance and reliability are improved, and high feasibility and practicability are achieved.
Description
Technical field
The present invention relates to a kind of cable assembly, particularly a kind of port is the radio frequency co-axial cable subassembly of waveguide mouth.
Background technology
Waveguide coaxial converter spare is widely used in microwave circuit, it is the important passive device in radar equipment, precise guidance and the microwave test system, particularly at millimeter wave band and to through-put power occasion than high requirement is arranged, the Waveguide coaxial structure is the most effective switching device.
In microwave transmission system, usually adopt waveguide to connect between the different waveguide interface, but the waveguide requirement on machining accuracy is high, and be limited by the number that turns round, therefore be difficult to adapt to Complicated Spatial Structure, often need co-axial cable component transition switching, usually adopt two Waveguide coaxial conversion connectors and a radio frequency co-axial cable subassembly to realize connecting.But the method has been introduced 3 parts and 2 discontinuous interface section, has reduced the reliability of system, and is unfavorable for the lifting of properties of product.
Summary of the invention
Technology of the present invention is dealt with problems and is: overcome the deficiencies in the prior art, provide a kind of and can reliably realize between diverse location waveguide mouth connecting or the waveguide mouth is connected the waveguide port radio frequency co-axial cable subassembly that connects with the radio-frequency (RF) coaxial interface.
Technical solution of the present invention is: a kind of waveguide port radio frequency co-axial cable subassembly, comprise a radio frequency coaxial-cable and the waveguide opening connector that directly connects at least one end of described radio frequency coaxial-cable, described waveguide opening connector comprises the waveguide side plate, attachment screw, coaxial side plate, the cable clamp nut, cable sleeve, jack and jack clamp nut, the waveguide side plate is fixedly connected with by attachment screw with coaxial side plate, fluted on one side of waveguide side plate, described groove and coaxial side plate are adjacent to rear formation waveguide mouth, the standard waveguide mouth that the size of waveguide mouth and corresponding frequency band are adaptive measure-alike; Cable sleeve is socketed on the radio frequency coaxial-cable, and the cable clamp nut is adjacent to the end face of the end face of cable sleeve and coaxial side plate fixing; Waveguide side plate and coaxial side plate are provided with through hole, and jack is fixedly connected with the waveguide side plate by the jack clamp nut after passing described through hole, and an end of jack is springhole and reliably contacts with the center conductor of radio frequency coaxial-cable.
When two ends of described radio frequency coaxial-cable directly connected the waveguide opening connector simultaneously, the axis of two waveguide mouths had been 0 °～180 ° perpendicular to the angle between the projection line on the radio frequency coaxial-cable axis plane.
Described radio frequency coaxial-cable is flexible cable, perhaps semi-flexible cable, and perhaps semi-rigid cable, the length of radio frequency coaxial-cable is fixing.
The present invention's advantage compared with prior art is: the invention provides and a kind ofly realize between diverse location waveguide mouth connecting or the waveguide mouth is connected the reliable fashion that connects with the radio-frequency (RF) coaxial interface.Because standardization of waveguide mouth size, can be according to using frequency range to inquire the standard size of corresponding waveguide mouth, therefore the cable assembly end is designed to the adaptive waveguide mouth of corresponding frequency band, directly the waveguide mouth of cable assembly is connected with system waveguide mouth during use to get final product.Because coaxial cable can be crooked arbitrarily, and can satisfy the random length needs, therefore this cable assembly space adaptability is good, connection between can optional position, implementation space waveguide mouth, compare former radio frequency co-axial cable subassembly and join number of components and two impedance discontinuity interface section that the mode of waveguide coaxial converter has reduced drawing-in system, can improve the reliability of system, have higher feasibility and practicality.
