Description
Technical field
The present invention relates to constructional devices and method that one kind can compensate waveguide length deviation automatically, are particularly suitable for compensating
Crossing cabin waveguide is due to processing and assembling bring length dimension deviation on the spacecrafts such as satellite, it is ensured that connects between waveguide and antenna
Reliably, antenna is fixed reliable.
Background technique
Compared with cable, waveguide transmission is high-efficient, it is big to bear power, very widely used in space industry.Usually
In the case of, waveguide is fixed out of spacecraft modules such as satellites to sequence installation out of my cabin, by waveguide and spacecraft deck board machining accuracy and
The position of the mouth of waveguide out of my cabin of the influence of rigging error, final stage and antenna connection can generate deviation, influence the installation of antenna
With fixation, conventional antenna holder uses the fixed form compressed along waveguide axial direction, cannot compensate and adapt to automatically these deviations.
It is in response to this, currently used that there are two types of solutions, first is that the waveguide that final stage is connect with antenna uses flexible waveguide,
Second is that being added gasket between antenna holder and antenna.
It is the deformation using flexible waveguide itself permission come Active Compensation deviation using the characteristics of flexible waveguide.Common flexible waveguide
Insertion Loss waveguide harder than common metal is high, and environmental suitability is poor, and price is also relatively high.
The scheme of shimming is ready gasket in advance, when assembly according to actual deviation amount between antenna holder and antenna
Gasket is added and carrys out compensating length deviation.Due to cannot accurately predict deviation before waveguide installation, need to prepare multi-thickness in advance
Gasket, often only can use a small amount of gasket when practical set, extra gasket can be then wasted.Either single gasket,
Or the combination of multiple pads can only all compensate most deviation, cannot accurately compensate all deviations.Further, since needing more
Secondary trial assembly and measured deviation value, complicated for operation, assembly efficiency is lower.
Therefore, either conventional aerial bracket adds flexible waveguide method or conventional aerial bracket to be added gasket method, all cannot
Waveguide length deviation is solved the problems, such as very well.
Summary of the invention
In order to overcome the disadvantages mentioned above of the prior art, the present invention provides a kind of antenna of adaptive waveguide length deviation companies
Binding structure and method adapt to and compensate automatically waveguide length deviation using antenna holder, and installation is simple and reliable, low in cost, no
Increase the loss of waveguide transmission feeder line.
The technical solution adopted by the present invention to solve the technical problems is: a kind of antenna company of adaptive waveguide length deviation
Binding structure is arranged antenna holder outside waveguide and antenna, is uniformly distributed with kidney slot along the circumference on antenna holder, connects using first
Connect the fixed final stage waveguide of screw and antenna；Antenna holder is fixed in spacecraft deck board using the second attachment screw, is adopted
The hole reserved on kidney slot and antenna on antenna holder is sequentially passed through from outside with third attachment screw, and antenna is fixed on day
On line bracket.
The present invention also provides a kind of antenna connection method of adaptive waveguide length deviation, when installation out of spacecraft module
It is sequentially connected fixed waveguide to out of my cabin, is connected and fixed before final stage waveguide out of my cabin and antenna, first covers antenna holder in wave
It leads and antenna outside；Final stage waveguide and antenna are fixed and then by antenna holder along waveguide axis with the first attachment screw
It contacts, then antenna holder is fixed in spacecraft deck board with the second attachment screw, most until with spacecraft deck board to moving down
It passes through the kidney slot being uniformly distributed along the circumference on antenna holder using third attachment screw again afterwards antenna is fixed on antenna holder, benefit
Waveguide length deviation is adapted to and compensated automatically with kidney slot.
Compared with prior art, the positive effect of the present invention is:
The content of present invention, which essentially consists in, improves antenna holder structure, adapts to and compensate automatically waveguide using improved bracket
Length variation specifically includes:
(1) fixed form between antenna holder and antenna is innovated, attachment screw is compressed by traditional along waveguide axial direction
Fastening means is changed to the compression mode along waveguide radial direction, as shown in Figure 1.
(2) will be designed on antenna holder with the screw hole at the antenna place of being connected and fixed kidney slot (length of kidney slot according to
Waveguide maximum deviation range determines), the automatic variation for adapting to antenna connector position caused by waveguide length deviation, to reach
It compensates the purpose of waveguide deviation and realizes and antenna is reliably fixed, as depicted in figs. 1 and 2.
Antenna holder structure proposed by the present invention is simple, easy installation and reliable, is adapted to automatically using the kidney slot on bracket
With compensation waveguide length deviation, it is no longer necessary to which flexible waveguide and gasket do not increase the loss of waveguide feeder, low in cost.
