[0001] The utility model belongs to the technical field of signal switching, and in particular relates to a shielded darkroom waveguide and a radio frequency signal switching device. Background Art

[0002] Most of the signal transmission in the RF microwave field requires transmission lines for signal conduction. Among them, coaxial lines and waveguide tubes are the two most widely used forms of transmission lines. These two transmission lines have great differences in size, material and transmission characteristics. In order to interconnect the two transmission lines, an intermediate conversion structure is required, which is the waveguide coaxial adapter.

[0003] The purpose of widening the frequency band is achieved by adjusting the depth of the conductor probe vertically inserted into the adapter. In the prior art, the coaxial end and the conductor probe are threadedly connected, and the insertion distance of the conductor probe is adjusted by adjusting the depth of the threaded connection. However, when the insertion distance is shallow, the stability of the threaded connection is poor. Therefore, a technical measure is proposed to solve the problem that in the prior art, the insertion distance of the conductor probe is adjusted by adjusting the depth of the threaded connection, and the stability of the threaded connection is poor when the insertion distance is shallow.

[0016] The utility model provides a lifting plate, which is moved to change the depth of the conductor probe inserted into the main body, so as to prevent the situation that the distance of the threaded connection between the connecting pipe and the threaded sleeve is short and the stability of the connection is reduced.
