Description
Technical field
The utility model relates to Electromagnetic Wave Propagation technology, particularly a kind of I type waveguide junction.
Background technology
In microwave system, between microwave component, need to do relative motion by joint, keep again electrical connection good between them simultaneously.For example: the high frequency transmission line of radar just needs to rotate at any time when carrying out conical scanning thereupon, but transmitter and receiver is motionless, and the transmission line being connected with them is also motionless.For Antenna+Transmitter and receiver are communicated with, transmission line (waveguide) is just divided into two sections, and one section is connected with antenna and with antenna movement; Another section is connected with transmitter, receiver, is motionless.These two sections of waveguides mechanically will be done mechanical movement; And in electric transmission characteristic, to keep connected sum unimpeded, the microwave component that completes this annexation is exactly rotary joint.Rotary joint consists of two sections of rectangular waveguides, and its inside is provided with choke groove.But this waveguide junction internal structure is complicated, and two sections all need special processing, assembling, existing rotary joint electrical connection properties is also not ideal enough simultaneously.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of simple in structure, I type waveguide junction that electrical connection properties is desirable is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of I type waveguide junction, it comprises rectangular waveguide one, rectangular waveguide two, ring flange one, bearing, ring flange two and flange seat, it is characterized in that: rectangular waveguide one is arranged in bearing, bearing is arranged in flange seat, ring flange one is arranged on rectangular waveguide one, ring flange two is arranged on rectangular waveguide two, rectangular waveguide one connects in line with rectangular waveguide two, on the port surface of rectangular waveguide two, be provided with choke groove, the structure of choke groove is circular recess, rectangular waveguide two is arranged on the end face of flange seat.
Described rectangular waveguide one is arranged at the left side of rectangular waveguide two, and ring flange one is arranged on the left side of rectangular waveguide one, and ring flange two is arranged on the right side of rectangular waveguide two.
The utlity model has following advantage: (1) choke groove of the present utility model is opened on the port surface of rectangular waveguide two, simple in structure, is easy to realize by machine work.(2) on an end face of rectangular waveguide one and rectangular waveguide two, be separately installed with ring flange one and ring flange two, easy for installation, easy to manufacture, electrical connection properties obviously improves simultaneously.
Accompanying drawing explanation
