Description

TECHNICAL FIELD

[0001] The utility model relates to communication technical field especially relates to a single ridge waveguide coaxial converter. BACKGROUND

[0002] In various radar systems, precise signal transmission in the field of radio frequency microwave, except that the transmission of wireless signals does not require transmission lines, most scenarios still need transmission lines to conduct signals, among which coaxial lines and waveguides are widely used to transmit microwave radio frequency energy. The most widely used waveguide on the market is a rectangular waveguide, and the most commonly used coaxial line in communication is a 50Ω coaxial cable assembly. These two transmission lines have huge differences in size, material and transmission characteristics. However, due to their wide application, situations often arise where the two transmission lines need to be interconnected. In this case, a waveguide coaxial converter is needed. Waveguide coaxial converters are indispensable in various radar systems, precision guidance systems and test equipment.

[0003] The existing waveguide coaxial converter installation method is to align the threaded holes on the cover plate with the threaded holes on the external device, and then place the screws into the threaded holes and rotate and tighten them. During installation, the screws are only placed in the threaded holes. If the waveguide coaxial converter shakes, the screws will fall off, affecting the convenience of disassembling and assembling the waveguide coaxial converter.

[0004] The existing patent (publication number: CN219393670U) discloses a wideband ridge waveguide coaxial converter. This utility model twists the installation screws in reverse. When the installation screws are rotated in reverse in the external threaded holes, they will move to the left. The spring's rebound force will push the transmission block to move to the left, thereby pushing the connecting block to move to the left and moving the installation screws back to their original positions. The installation screws stop moving and can always be located on the cover plate, so they will not fall off during disassembly and assembly. This design improves the convenience of disassembling and assembling the waveguide coaxial converter and saves the number of tools needed for disassembly and assembly.

[0005] To solve the above problems, the existing patent provides a solution. However, the elastic fastening bolt structure used in the above-mentioned patent has practical application problems. Each structure needs to be pre-installed in the movable slot to prevent the installation screws from falling out. However, this design is inconvenient to operate. During installation, not only do you need to accurately install the components into the movable slot according to specific steps, but you also need to fine-tune to ensure that the bolts work properly. After long-term use, when the threads of the installation screws are worn and cause the bolts to jam, you need to replace them. However, you cannot disassemble them properly. In high-demand places, this leads to difficult equipment maintenance, high costs, affects the performance of the converter, and interferes with the normal operation of the system, which is not conducive to the long-term use of the equipment.

[0006] Therefore, a single ridge waveguide coaxial converter is proposed. UTILITY MODEL CONTENTS
