Embodiment
Please with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4.Fig. 1 for microwave antenna subsystem of the present invention explosive decomposition figure, Fig. 2 be the front view of microwave antenna subsystem of the present invention, Fig. 3 be an A zoomed-in view partly among Fig. 3 for A-A cutaway view, Fig. 4 of microwave antenna subsystem of the present invention.Microwave antenna subsystem of the present invention comprises metallic reflection face, feed 20 and the sealing ring 40 of integrated injection molding, and a plurality of screws 30 pass a plurality of first screwed holes 2011 that are arranged at feed 20 and a plurality of second screwed holes 112 that are arranged at metallic reflection face end 11 with locking feed 20 and metallic reflection face.
Metallic reflection face comprises the main body 10 and the columned end 11 of parabolic shape, and the one-body molded and inner hollow in main body 10 and end 11 is in order to reflection or converge electromagnetic wave.11 centers, end form through hole 111, and through hole 111 sizes and shape are corresponding to the port 202 of feed 20.Through hole 111 peripheries also are formed with concave part 113, the shape of concave part 113, size is consistent with sealing ring 40 and the thickness of sealing ring 40 greater than the degree of depth of concave part 113.Concave part 113 peripheries also comprise a plurality of second screwed holes 112.
The main effect of sealing ring 40 is the gap that forms between sealing feed 20 and the metallic reflection face end 11, so its size and shape are not done requirement.The groove 113 of corresponding rectangle adopts the sealing ring of hollow, rectangular frames in the present embodiment, and consistent and its thickness of the concave part of its frame size and shape and metallic reflection face end 11 113 is greater than the degree of depth of concave part 113.Sealing ring 40 can be processed also and can and comprise that the external conductive rubber of interior metal net constitutes by the interior metal net through in silica gel, mixing metal powder.Thereby the sealing ring 40 that dual mode is processed all not only can guarantee the elasticity of sealing ring 40 and guarantee the sealing characteristics of sealing ring 40 but also can prevent electromagnetic leakage that the loss that reduces antenna improved antenna performance.And also the one-body molded sealing ring elasticity that forms is good than the sealing ring of processing at conductive rubber internal package wire netting through in silica gel, adding metal powder, and technology is simple, and parameter is easy to be controlled to be the preferred embodiment for the present invention.
In the assembling process; Earlier sealing ring 40 is positioned in the concave part 113 of metallic reflection face end 11; Secondly feed 20 is replaced metallic reflection face end 11 makes the through hole 111 of port 202 corresponding to metallic reflection face end 11; At last a plurality of screws 30 are passed first screwed hole 2011 and second screwed hole 112 of the metallic reflection face of passing end 11 on the feed fixed part 201, fixedly feed 20 and metallic reflection face behind the tighten the screws 30.Because sealing ring 40 thickness are greater than concave part 113 degree of depth, when screw 30 is tightened, thereby sealing ring 40 is squeezed and seals feed 20 and metallic reflection face to greatest extent.Simultaneously, thereby sealing ring 40 inner doping metals powder make electromagnetic wave not leak from sealing ring, reduce the electromagnetic consumable of antenna and have improved the performance of antenna.
Fig. 5 is positioned over the part enlarged drawing of second execution mode between feed and the metallic reflection face for sealing ring.The difference of itself and Fig. 4 is that concave part 113 is arranged on the feed fixed part 201.
Fig. 6 is arranged at the part enlarged drawing of the 3rd execution mode between feed and the metallic reflection face for sealing ring.The difference of itself and Fig. 4 is that concave part 113 is made up of with the groove that is arranged at feed fixed part 201 groove of the metallic reflection face of being arranged at end 11 jointly.Thereby adopt this type of design to make sealing ring 40 press metallic reflection face and feed to make that both sealing effectivenesss are better at the time-division don't push that is locked.
Combine accompanying drawing that embodiments of the invention are described above; But the present invention is not limited to above-mentioned embodiment, and above-mentioned embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of forms, these all belong within the protection of the present invention.
