Technical field

The present invention relates to antenna back frame technical field, especially a kind of split-type composite material multi-pass for antenna back frame Connector.

Background technique

Reflector antenna plays an important role in terms of satellite communication, especially the polar region in no mobile communication base station, polar region Scientific investigation personnel exchange with the external world to carry out satellite communication by reflector antenna.However polar region atrocious weather, to reflecting surface The working performance of antenna has initiated challenge, and traditional metallic reflection surface antenna is under the environment of polar region and generates due to expanding with heat and contract with cold Obvious deformation, seriously affects Antenna Operation performance, working life significant attenuation；The polar region effective working time is short simultaneously, backrest Assembly time limited.So designing and producing a can cope with polar region severe cold weather and can be with the reflector antenna of quick assembling Backrest is an important engineering problem.

Composite material is the hot spot application material of engineering field in recent years, due to light weight, intensity height, thermal expansion coefficient The features such as low, is widely used in various engineering products, and starts the use for gradually substituting metal material.So utilization is compound The low feature of material thermal expansion coefficient, the important component of reflector antenna --- antenna back frame will be all using composite materials Design will be used to resist the deformation of severe cold bring backrest, and meet polar region working condition requirement, and stabilized antenna performance improves Antenna Operation Service life.

However, reflecting surface antenna back frame is due to rod piece junction mostly big, the backrest rod piece of full composite material with conode number Between connection there are certain difficulty, and since composite material does not have the welding advantage of metal, multiple material multiple-pass joint at For one of the design difficulty of antenna back frame, the design form of multiple material multiple-pass joint finally determines backrest assembly difficulty.

China Patent Publication No. CN109667817A is disclosed in entitled " a kind of carbon fibre composite multiple-pass joint " A kind of composite material multiple-pass joint structure.Branch when although its two-flap type structure of the inventive structure solves complex truss Standard Siphunculus can not be inserted into the contradiction of the corresponding connector in its both ends, but there are the following problems:

1. the multiple-pass joint in the invention uses carbon fiber prepreg non-autoclave skill by 3/4 valve structure and 1/4 valve structure Art molding.It is weaker in the intersection intensity of two valve structures which results in connectors, is easy impaired.

2. the multiple-pass joint in the invention applies Mr. Yu's truss structure, truss assembly is needed by truss structure assembler Dress is glued the accurate assembly for realizing truss structure leverage and multiple-pass joint by wet process.Therefore the invention is not suitable for needing fast The truss structure for the reflecting surface antenna back frame that quick-mounting is matched.

Summary of the invention

The present invention is in order to solve the problems, such as that existing multiple-pass joint intensity is weaker, is not easy to assemble at present, and the one kind provided Split-type composite material multiple-pass joint for antenna back frame.

In order to achieve the above functions, present invention provide the technical scheme that

A kind of split-type composite material multiple-pass joint for antenna back frame, including adapter body, left connector cover board and the right side Connector cover board；The adapter body, left connector cover board and right connector cover board are made of composite material；The adapter body is one Body structure and be equipped with more than one circular sleeve；It is respectively equipped on the outside of the left connector cover board and the right connector cover board More than one circular sleeve, inside are respectively equipped with the groove with the cooperation of adapter body outer surface；It is the left connector cover board, described Right connector cover board passes through the edge of a wing web being arranged in the adapter body with the adapter body and is fixedly connected.

Preferably, the axis of the circular sleeve in the adapter body is met at a little and the angle of adjacent axis is 20 ° ~120 °；Offer several bolts hole on the edge of a wing web, the left connector cover board, the right connector cover board by bolt with The edge of a wing web is fixedly connected.

Preferably, the adapter body is equipped with the trailing arm of several support reflection surface panels, is provided with left and right pair on the trailing arm The bolt hole of title.

Preferably, the symmetrical cloth of median plane of the left connector cover board and the right connector cover board about the adapter body It sets.

Preferably, the fitting end of the circular sleeve is equipped with ladder rotary table or ring flange.

Preferably, the adapter body, left connector cover board and right connector cover board are formed using carbon fibre fabric prepreg, are adopted It is processed with autoclave molding or die press technology for forming.

The beneficial effects of the present invention are:

1, assembly is simple: being bolted is that most simple firm connection method, the present invention are connected using bolt in engineering connection It connects, multiple material multiple-pass joint three parts is connected as one, so that antenna back frame is easily assembled and is conveniently adjusted；

2, preparation is easy: monoblock type multi-pass, which answers material connector, has larger difficulty in manufacture forming, and the present invention connects multi-pass Head splits into adapter body, and three components of left connector cover board and right connector cover board manufacture respectively, can reduce manufacture difficulty in this way, The production of small lot easy to accomplish；

3, intensity is high: the three parts of split-type multiple-pass joint of the invention are all made of high strength light composite material, pass through Autoclave molding or die press technology for forming are integrally formed, and are equipped with edge of a wing web, can satisfy multiple-pass joint in bad working environments Under requirement.
