Description
Technical field
The invention belongs to aircraft radar antenna house fields, and in particular to a kind of sub-miniature A connector suitable for conformal antenna cover.
Background technique
The development trend of new concept weapon platform is exactly intelligent, unmanned, stealthyization and imitation biochemistry.This is to radar day
Linear system system proposes very big challenge, and the function of the following radar antenna system and physics framework is not only required to realize higher levels of collection
At, and require radar antenna system that can preferably be blended in weapon platform.It is flat that traditional radar antenna is directly mounted at weapon
Platform (aircraft, guided missile, naval vessel, satellite etc.) surface, or need individually to install radome additional and be protected, it is flat to will affect weapon
Pneumatic/Stealth Fighter of platform.Additional increased Antenna support structure and ancillary equipment, the then inside that will lead to weapon platform occupy
Space, weight, complexity and manufacture maintenance cost substantial increase.Therefore, antenna and the mutually independent conventional junction of antenna house
Configuration formula is difficult to adapt to the combat mode and functional requirement of weapon platform of new generation again, and conformal antenna cover comes into being, and becomes new
One of the emphasis direction of concept weapon platform development.
The general structure form of conformal antenna cover are as follows: be made and weapon platform surface using low dielectric, low-loss composite material
It is each to be embedded in a large amount of shapes in the molding fabrication stage of multilayer materials structure between the layers for conformal multilayer bearing structure
Metal patch, TR circuit, feeding network, thermal controls apparatus that exclusive or is periodically placed etc. form complicated multilayer conformal array
Array structure.Conformal antenna cover has the characteristics that apparent structure-function integration, is the organic comprehensive of traditional antenna and antenna house technology
Application is closed, it is various that pneumatic weapon platform, stealthy, Information perception and processing, weight, working service etc. can be promoted well
Performance.
Conformal antenna cover is compared with conventional radar antenna house, in addition to having mechanical interface, goes back Ying Youyu external signal system
Interface, with meet power supply and signal transmission the needs of.The interface of conformal antenna cover and external signal system, especially by specific
Metal patch layer is realized with signal wire or the form of sub-miniature A connector welding.When using welding signal line mode, by signal wire one end
It is welded with metal patch layer designated position, the other end is led to outside conformal antenna cover.In engineering practice, the use of sub-miniature A connector
It is more universal.Sub-miniature A connector is mainly made of the part such as shell, auricle, stitch, and shell end portion has screw thread, can be believed with outside
Number system is spirally connected.SMA common used material is the preferable copper alloy of electric conductivity, internal fill insulant.When sub-miniature A connector is installed, need
Through-hole is produced on metal patch, dielectric layer, metal floor, stitch and metal patch layer designated position are welded, and SMA is connect
The auricle and metal floor of head carry out earth-continuity, usually carry out welding or being spirally connected by the through-hole on auricle.Conventional sub-miniature A connector
Using object be conventional planar circuit board, the technical need of conformal antenna cover cannot be adapted to completely, mainly there is following problems.
Firstly, the use environment of conformal antenna cover is more harsher than conventional planar circuit board, pneumatic, vibration, punching are born
It hits, the load of the diversified forms such as heat, the stress/strain of inside configuration is larger, and the single stitch welding manner of conventional sub-miniature A connector holds
Easily there is the phenomenon of bonding strength deficiency, it is possible to lead to solder joint fracture failure.
Secondly, conformal antenna cover main body structure is usually nonmetallic composite sandwich.The composition of metal floor is logical
It is often in relatively thin one layer of copper membrane of composite material skin (thickness is usually more than 1mm) surface paving (about 18 μm of thickness).SMA
When connector and metal floor are connected, auricle no matter is taken to weld or be spirally connected by the through-hole on auricle, existed some tired
It is difficult: easily to be welded using welding manner and hurt metal layer, quality of welding spot is poor；Using screw connection manner then since covering is relatively thin it is difficult to ensure that connection
Reliability, be unfavorable for earth-continuity.
In addition, conformal antenna cover is usually curved profile, for planar circuit board design sub-miniature A connector in terms of according with shape
Need Optimal improvements.The metal floor of the conformal antenna cover of the auricle and curved profile of especially conventional sub-miniature A connector can not be complete
Shape fitting is accorded with, connection and earth-continuity are unfavorable for.
Summary of the invention
The present invention relates to a kind of sub-miniature A connector, working frequency range is not more than 6GHz, the feedback suitable for conformal antenna cover metal patch
The ground connection of electricity and metal floor.It is of the present invention for the use environment, curved profile and special construction of conformal antenna cover
Sub-miniature A connector can effectively improve the reliability of stitch Yu metal patch solder joint, and accord with shape with metal floor, guarantee good lead
It is logical, better meet the technical need of conformal antenna cover feed and ground connection.
Technical solution
A kind of sub-miniature A connector suitable for conformal antenna cover, sub-miniature A connector mainly consist of three parts.In adapter body, 1 is
