Description

The microwave coaxial waveguide switch

Technical field

The utility model relates to a kind of waveguide coaxial converter, particularly a kind of microwave coaxial waveguide switch.

Background technology

In microwave transmission system; Usually can run into the situation that coaxial equipment docks with plumbing; This just needs a kind of transition apparatus, not only structurally can both be coupled together, the more important thing is both are linked up after; Electrical property is unaffected basically, and this just makes this device need hang down standing-wave ratio and low differential loss.This device is exactly the coaxial waveguide transducer.

Traditional coaxial waveguide transducer, perhaps because the restriction of design level, or because the restriction of level of processing makes the coaxial waveguide transducer demonstrate complex structure more, consistency and poor reliability, the process-cycle is long, and rate of finished products is low, shortcomings such as cost height.

Continuous development along with society; Requirement for communication equipment is also increasingly high; Simultaneously, because scientific and technological progress and market competition, the price of communication equipment is also more and more lower; Obviously the coaxial waveguide transducer of conventional method design and making can not address that need, and this just needs to improve method for designing and manufacture craft satisfies this demand.

Summary of the invention

To defective or deficiency that above-mentioned traditional coaxial waveguide transducer exists, the utility model adopts following technical solution:

A kind of microwave coaxial waveguide switch; Comprise rectangular waveguide section and coax segments; The rectangular waveguide top is provided with one through to the inner circular hole of waveguide segment; Rectangular waveguide one side is arranged to the waveguide short end, and rectangular waveguide opposite side and ring flange link into an integrated entity, and coax segments is connected with the rectangular waveguide section through circular hole.

The utility model also has the other technologies characteristics:

Described coax segments is made up of inner wire probe, outer conductor and medium; Outer conductor is arranged on the coax segments upper end; Inner wire probe and medium are deep into rectangular waveguide inside through outer conductor, and wherein the inner wire probe passes medium and places the formed interior volume of rectangular waveguide.

Described inner wire probe, outer conductor and medium three parts are crimped on together along same axis.

Described rectangular waveguide top be provided with through to the center line of the axis of the inner circular hole of waveguide segment and rectangular waveguide on same plane and mutual vertical.

The beneficial effect that the utility model adopts above-mentioned solution to reach is: in light weight, compact conformation is simple, has saved the space, has dwindled volume, compares traditional coaxial waveguide conversion; No stepladders conversion, no adjusting device does not have coupling mechanism, need not welding, the one forging molding; Be prone to processing, be prone to assembling, consistency and reliability are high, and rate of finished products is high, are suitable for producing in enormous quantities; Cost is low, need not to transfer to survey, and is with short production cycle, excellent electrical properties.

Embodiment

Like Fig. 1-shown in Figure 3; The utility model is a kind of microwave coaxial waveguide switch; Comprise rectangular waveguide section 2 and coax segments 1, rectangular waveguide 4 tops are provided with a circular hole 6 through to waveguide segment 2 inside, and rectangular waveguide 4 one sides are arranged to waveguide short end 2; Rectangular waveguide 4 opposite sides and ring flange 3 link into an integrated entity, and coax segments 1 is connected with rectangular waveguide section 2 through circular hole 6.

In order to make the electric property of microwave coaxial waveguide transitions accomplish fine; Then require to confirm the length and the diameter of inner wire probe 7; Waveguide short end 5 reaches best to probe 7 apart from these several sizes, through design of Simulation, makes electric property reach the best and confirms this several sizes.

Traditional coaxial waveguide conversion is because design is very unreasonable; In order to reach good electric property, often to add some step conversion, or adjusting device; Or coupling mechanism; For simplified structure, the simulation software through the advanced person the electric property of simple structure be designed into best reaching designing requirement, thereby make structure obtain maximum simplification.

Coax segments 1 is made up of inner wire probe 7, outer conductor 9 and medium 8; Inner wire probe 7, outer conductor 9 and medium 8 three parts are crimped on together along same axis; Outer conductor 9 is arranged on coax segments 1 upper end; Inner wire probe 7 is deep into rectangular waveguide 4 inside with medium 8 through outer conductor 9, and wherein inner wire probe 7 passes medium 8 and places rectangular waveguide 4 formed interior volume.Rectangular waveguide 4 tops be provided with through to the center line of the axis of the inner circular hole 6 of waveguide segment 2 and rectangular waveguide 4 on same plane and mutual vertical.Design on the said structure also makes the utility model better appearance, has at utmost saved material.

Processing for ease simultaneously, shortened process reaches the purpose of the material-saving that saves time; With rectangular waveguide 4, ring flange 3 processes through the forging method one with short-circuit end 5, does the production procedure of also having saved welding like this; Location of short circuit also can accurately be fixed, and has improved consistency.

The utility model can be implemented with other various forms under the situation of not leaving its spirit and principal character.Therefore the above-mentioned all main points of example of executing are only explained, rather than determinate explanation.The scope of the utility model is the described scopes of claims, does not receive the restriction of specification.All distortion or changes that belongs to the equivalent scope of claims all belong in the scope of the utility model.
