Description

A waveguide device connection device

technical field

The utility model relates to the technical field of waveguide devices, in particular to a connection device for waveguide devices.

Background technique

Most of the signal transmission in the RF microwave field requires transmission lines for signal conduction, among which coaxial transmission lines and waveguide transmission lines are the most widely used. The waveguide is usually made of metal material, with a circular or rectangular cross-section, and the cavity is filled with air medium. It is one of the most commonly used transmission systems in microwave technology. The coaxial line is a guiding system composed of two coaxial cylindrical conductors, and a broadband microwave transmission line filled with air or high-frequency medium between the inner and outer conductors. The two transmission lines have huge differences in size, material and transmission characteristics. A waveguide-to-coaxial converter is required to interconnect the two transmission lines.

The waveguide-to-coaxial adapter is a microwave device with a wide range of uses. It is a key device for signal connection of antenna feeding systems, transceiver components and other equipment in the fields of microwave communication, radar search, and electronic countermeasures. Its main function is to realize Transition conversion of microwave signals in both waveguide and coaxial transmission systems. At present, the structure of a typical waveguide-to-coaxial adapter is shown in Figure 1, which consists of a flange plate, a standard waveguide, a short-circuit block and a coaxial connector.

As shown in Figures 2 and 3, a typical waveguide coaxial converter is connected to a waveguide device of the same series of flanges. Figure 2 shows the state when the waveguide coaxial converter is separated from the waveguide load. Each standard flange is provided with two positioning pins and pin holes corresponding to the mirror images. When the two components are inserted into each other, the respective pins are inserted into the other pin holes. Positioning is performed to ensure that the direction and position of the rectangular waveguide cavity in the waveguide are aligned, and the waveguide cavity is accurately docked. As shown in Figure 3, after the pins are inserted, four screws are used to lock and fix the flanges on both sides to ensure that the contact ends of the two waveguides are tightly attached to meet the electrical connection and microwave transmission requirements.

As mentioned above, the typical waveguide device is connected through the standard flange using traditional screws. As shown in Figure 1, the standard flange has a cylindrical step in the middle of the flange, and the waveguide port is located on the end face of the cylindrical step. The protruding step end face is used as the electrical contact end face when the flanges on both sides are connected, and the processing quality is required to be high, the smoothness is required to be good, and it is perpendicular to the waveguide cavity. If the processing quality of the step surface is poor, when the two sides are butted together, the end faces will not be in good contact, and even a space will be formed at the waveguide port, which will change the shape of the inner cavity of the waveguide, thereby affecting the electrical performance. Therefore, whether the cylinder end face contact on the flange is good is very important to the overall electrical performance. In the typical connection mode shown in Figures 2 and 3, the aforementioned poor contact of the end face may occur. As shown in Figure 4, if the four screws are not pre-tightened one by one, but are directly locked one by one, the flange will tilt, even if there are already inserted positioning pins. After partial calibration, the two flanges will still be tilted, and the end faces of the cylinder cannot be completely fitted, and the connection between the two waveguide cavities will be abnormal, which will affect the overall electrical performance.
