Description
Technical Field
The utility model relates to the technical field of waveguide devices, in particular to a waveguide device connecting device.
Background
In signal transmission in the field of radio frequency microwave, transmission lines are mostly required for signal transmission, and coaxial transmission lines and waveguide transmission lines are most widely used. Waveguides are usually made of metallic material, are round or rectangular in cross-section, are filled with an air medium in a cavity, and are one of the most commonly used transmission systems in microwave technology. The coaxial line is a broadband microwave transmission line consisting of two coaxial cylindrical conductors, and air or high-frequency medium is filled between the inner conductor and the outer conductor. The two transmission lines have great differences in size, material and transmission characteristics. Waveguide coaxial converters are required to interconnect the two transmission lines.
The waveguide coaxial adapter is a microwave device with wide application, is a key device for signal connection of equipment such as an antenna feed system, a transceiver component and the like in the fields of microwave communication, radar search, electronic countermeasure and the like, and mainly has the function of realizing transition conversion of microwave signals in waveguide and coaxial transmission systems. The structure of a typical waveguide-to-coaxial adapter is shown in fig. 1, and comprises a flange, a standard waveguide, a short-circuit block and a coaxial connector.
As shown in fig. 2 and 3, the waveguide coaxial converter is typically connected to a waveguide device having a flange of the same series. Fig. 2 shows a state of the waveguide coaxial converter when the waveguide load is separated from the waveguide load, two positioning pins and pin holes corresponding to mirror images are respectively arranged on respective standard flanges, and when two parts are inserted into each other, respective pins are inserted into the pin holes of the other part for positioning, so that the directions and positions of rectangular waveguide cavities in the waveguide tubes are aligned, and the waveguide cavities are accurately butted. As shown in fig. 3, after the pins are inserted, the flanges of the two sides are locked and fixed by four screws, so that the contact end surfaces of the two waveguides are tightly attached to each other, and the requirements of electrical connection and microwave transmission are met.
The typical waveguide device as described above is connected by conventional screws through a standard flange, such as the standard flange shown in fig. 1, which has a cylindrical step in the middle of the flange, the waveguide port is located on the end surface of the cylindrical step, and the end surface of the protruding step is used as an electrical contact end surface when the flanges on both sides are connected, and has high processing quality requirement, good finish and is perpendicular to the waveguide cavity. If the step surface has poor processing quality, the end surfaces of the two butted step surfaces have poor contact after the two sides are butted, even a space is formed at the port of the waveguide, the shape of the inner cavity of the waveguide is changed, and the electrical performance is further influenced. It is important for the overall electrical performance that the cylinder end face contact on the flange is good. In the typical connection shown in fig. 2 and 3, the end-face contact failure may occur. As shown in fig. 4, if the four screws are not pre-tightened one by one during manual locking of the four screws, the flanges are directly locked one by one to incline, even if the inserted positioning pins are partially corrected, the two flanges still incline, and the end faces of the cylinders cannot be completely attached, so that the connection of the waveguide cavities on the two sides is abnormal, and the overall electrical performance is affected.
