Description

Technical Field

[0001] The present invention relates to the technical field of waveguide devices, and particularly relates to a waveguide device connection device and a using method thereof. Background Art

[0002] In the signal transmission in the field of radio frequency and microwave, most signal transmissions require transmission lines. Among them, coaxial transmission lines and waveguide transmission lines are the most widely used. Waveguides are usually made of metal materials, have a circular or rectangular cross-section, and are filled with air medium in the cavity. They are one of the most commonly used transmission systems in microwave technology. A coaxial cable is a guiding system composed of two coaxial cylindrical conductors, and is a broadband microwave transmission line with air or high-frequency medium filled between the inner and outer conductors. These two types of transmission lines have huge differences in size, material, and transmission characteristics. To interconnect the two types of transmission lines, a waveguide coaxial converter is required.

[0003] A waveguide coaxial adapter is a very widely used microwave device and is a key device for signal connection in antenna feeding systems, transceiver components and other equipment in the fields of microwave communication, radar search, electronic countermeasure, etc. Its main function is to realize the transition and conversion of microwave signals between waveguide and coaxial transmission systems. The structure of a typical current waveguide-to-coaxial adapter is as Figure 1 shown, and it is composed of a flange, a standard waveguide, a short-circuit block and a coaxial connector.

[0004] As Figure 2 , 3 shown, it is the state of connection between a typical waveguide coaxial converter and a waveguide device of the same series of flanges. Figure 2 As shown in Figure 3 , when the waveguide coaxial converter is separated from the waveguide load, there are two positioning pins and mirror-image corresponding pin holes on each standard flange. When the two components are inserted into each other, their respective pins are inserted into the pin holes of the other party for positioning, so as to ensure that the direction and position of the rectangular waveguide cavity in the waveguide are aligned, and the waveguide cavities are accurately docked. As shown in

[0005] As described above, a typical waveguide device is connected by using traditional screws through a standard flange. As shown in Figure 1 the standard flange shown in Figure 1 , there is a cylindrical step in the middle of the flange, and the waveguide port is located on the end face of the cylindrical step. This protruding step end face serves as the electrical contact end face when the two flanges are connected. Its processing quality requirements are very high, requiring good surface finish and being perpendicular to the waveguide cavity. If the processing quality of this step face is poor, when the two sides are docked, the end face contact is poor, and even a space may be formed at the waveguide port, changing the shape of the waveguide inner cavity, thereby affecting the electrical performance. Therefore, whether the contact of the cylindrical end face on the flange is good is very important for the overall electrical performance. InFigure 2 , 3 In the case of the typical connection method shown, the aforementioned poor end face contact may occur. For example, Figure 4 as shown, when manually tightening four screws, if the four screws are not pre-tightened one by one but directly locked one by one, the flange will tilt. Even if there are inserted positioning pins for partial correction, the two flanges will still tilt, and then the end face of the aforementioned cylinder cannot be completely fitted, and abnormalities will occur at the connection of the two waveguide cavities, thus affecting the overall electrical performance. Summary of the Invention
