Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a high-power radio frequency coaxial switch. Background Art

[0002] A transmitting antenna is an electronic device that converts electrical signals into electromagnetic waves for transmission to a designated receiver, such as a broadcast station, satellite, wireless communication network, or radar system. A high-power RF coaxial switch, also known as a coaxial switch, is an electronic device used to switch between high-frequency RF signal paths. They are commonly used in communications, radar, satellite communications, radio signal processing, and wireless power transmission.

[0003] RF coaxial switches are electronic components based on microwave technology. They use a coaxial structure with multiple branches inside, each of which is connected to an input or output port. When a switch is activated, it allows the signal to pass through, while other branches are blocked, thereby achieving directional transmission of the signal. Current coaxial switches generally use a single mechanical rotating structure. Although it is easy to operate, the activation efficiency of the switch is low and the control method is relatively simple.

[0004] In summary, there is a need for a high-power RF coaxial switch with efficient switching and diversified control methods. Utility Model Content

[0033] 2. When the rotary guide assembly 7 is connected to the motor 6 and the manual knob 5 respectively, the connection and disconnection of the rotary guide assembly 7 and each plug core 31 can be controlled by the motor 6, and the manual knob 5 can also be rotated to control the connection of the rotary guide assembly 7, thereby improving the diversity of switch control.

[0036] Embodiment 2

The switching module controls the starting motor 6, and the motor 6 drives the rotating conductor 71 to rotate inside the housing 2, and the disconnection groove 711 of the rotating conductor 71 is moved away from the contact spring 72. The contact spring 72 slides and fits the side wall of the rotating conductor 71 using the triangular inclined surface.
