Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of radio frequency signal switching, specifically to a radio frequency signal switching device containing switching panel. BACKGROUND

[0002] The radio frequency signal fast switching system containing main and standby transmitters, such as communication base station system, broadcast television transmitting system, realizes the fast switching of the radio frequency signal of main and standby transmitters by using radio frequency signal switching device. In the related art, the authorized patent document with the application number 201920364705. X discloses a novel broadcast transmitter switching system, which comprises a radio frequency U-shaped coaxial connector one, a radio frequency U-shaped coaxial connector two, a radio frequency U-shaped coaxial connector three, a radio frequency U-shaped coaxial connector four, a coaxial switch and a mounting panel. The four radio frequency U-shaped coaxial connectors are installed on the same plane, the coaxial switch faces backward, and the four ports of the coaxial switch are oppositely installed with the ports of the radio frequency U-shaped coaxial connectors. The four ports of the coaxial switch are respectively connected with the lower ports of the radio frequency U-shaped coaxial connector one 1, the radio frequency U-shaped coaxial connector two 2, the radio frequency U-shaped coaxial connector three 3, and the upper port of the radio frequency U-shaped coaxial connector four 4. When the coaxial switch cannot work normally, the system can ensure the normal operation of the broadcasting system by changing the installation position of the radio frequency U-shaped coaxial connector. However, there are two important defects in the use of the scheme: first, when the coaxial switch 5 cannot work normally, the radio frequency source A 7 and the antenna 9 or A 8 or the antenna 9 are connected by changing the position of the radio frequency U-shaped coaxial connector, and the coaxial switch 5 is by-passed. The important defect is that the connection of any non-working radio frequency source (A 7 and the antenna 9 are connected, A 8 is not working as a backup radio frequency source, and vice versa, A 7 is not working as a backup radio frequency source) and the dummy load 10 needs to pass through the coaxial switch 5, which will cause the change of the position of the radio frequency U-shaped coaxial connector and the complete by-pass of the coaxial switch 5. Second, the four radio frequency U-shaped coaxial connectors in the scheme are vertically arranged, especially the radio frequency U-shaped coaxial connectors 1, 2 and 3, and the distance between them is very close. In actual switching, the space limitation will cause inconvenience in switching operation. Therefore, the present application provides a radio frequency signal switching device containing switching panel. CONTENT OF THE UTILITY MODEL
