[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
See also Fig. 1 and Fig. 2, in the strip line radio-frequency unit encapsulating structure preferred embodiment of the utility model, this encapsulating structure comprises block 1, reflecting plate 2, media supports 3 and strip line radio-frequency unit 4.
Said reflecting plate 2 is a metal material.Reflecting plate 2 is positioned at the bottom of strip line radio-frequency unit 4, and it supports a strip line radio-frequency unit 4 through some media supports 3 of passing reflecting plate 2, and reflecting plate 2 is also preset to be supplied and 1 other screw 20 of screw lock mutually of blocking a shot.Reflecting plate 2 has certain thickness and intensity, and its concrete thickness and material model can change flexibly, and structurally, reflecting plate 2 plays the effect of fixing block 1 and strip line radio-frequency unit 4.
Said block 1 have a rectangular-shaped top plate 1t and perpendicular to top board 1t with the one side four abutment wall 1s; Block 1 is an one die cast spare; Can adopt aluminium alloy, kirsite etc. to be cast into type; According to radio-frequency unit electrical characteristic needs, block 1 size and shape can change flexibly, as it is round or irregularly shaped etc. to be made into other polygon.
The top board 1t of said block 1 and four abutment wall 1s have defined a groove shape chamber 101 (consulting Fig. 3) together, and when block 1 fixed with button and reflecting plate 2, its groove shape chamber 101 just was used to hold said strip line radio-frequency unit 4.
The two ends of said block 1 are provided with two connectivity ports 5; Two connectivity ports 5 connect block 1 self; The inner wire of being convenient to outside radio frequency cable passes and is connected with this strip line radio-frequency unit 4 afterwards, and the outer conductor of radio frequency cable 7 then can weld with the wall of connectivity port 5 mutually.Being provided with of connectivity port 5 numbers of block 1 and position is very flexible; Its number mainly is total number of the signal input that adapts to said strip line radio-frequency unit 4, output and being provided with, and its position is then so that make the inner wire of external radio frequency cable 7 be connected with those inputs, output to be as the criterion.Therefore, for the power division network strip line radio-frequency unit 4 that works the power division effect that is divided into two, block 1 can be provided with three connectivity ports 5, by that analogy.For the ease of block a shot 1 with the inner wire of the radio frequency cable 7 of outside is connected after reflecting plate 2 is fixing corresponding some perforations 1 self welding window 6 of blocking a shot of offering on block 1 with strip line radio-frequency unit 4.Obviously, the position of this welding window 6 is corresponding with the link that the need of strip line radio-frequency unit 4 connect, and promptly is positioned at said each connectivity port 5 adjacent to, and suitable the connection with said each connectivity port 5 is integral.
The surface of said block 1 has the coat of metal, so that the outer conductor of external radio frequency cable 7 welds with it.
Please further combine Fig. 3; On the edge of the abutment wall 1s orientating reflex plate 2 of said block 1, be provided with some screws 10, those screws 10 are corresponding one by one on the position with said screw 20 on the said reflecting plate 2; Like this; After can passing the screw 20 of reflecting plate 2 through screw 8,, make reflecting plate 2 realize firmly being connected between 1 with blocking a shot with the screw 10 of block on 1 screw lock mutually.Because lock with screw 8 between reflecting plate 2 and the block 1, therefore, this connection can be regarded the connection of a contact as.Block 1 is except that with reflecting plate 2 carries out a position that contacts; Other position of its four abutment wall 1s all is processed into shorter size; After making that block 1 and reflecting plate 2 lock; Have certain distance between other position of said four abutment wall 1s and the reflecting plate 2, thereby form the slit, this distance must be greater than zero.Through this structure, no longer be that line contact between block 1 and the reflecting plate 2, but put the contact installation, the quantity of the screw 8 that is used to lock significantly reduces, and makes the locking effect of screw 8 be easy to Be Controlled, thereby, make the passive intermodulation index more controlled.The number of some contact usually, can firmly be installed in order to make between block 1 and the reflecting plate 2 by screw 10, the 20 numbers decision on said block 1 and the reflecting plate 2; Their screws 10,20 separately should be two or more, and are preferable, on block 1 and reflecting plate 2, four screws 10,20 are set respectively; Roughly be distributed in four jiaos; Like this, counting of some contact is moderate, and it is still firm to connect effect.
In like manner, at the utility model among other embodiment that does not disclose, the mode that block 1 contact with point between the reflecting plate 2 can be with the riveted way realization, also can be the mode of welding.Those skilled in the art are after reading over the utility model, and class is released other known mechanical bond mode in view of the above, are used for realizing the similar techniques scheme of the utility model.
In the utility model; Media supports 3, strip line radio-frequency unit 4 are assembled and are fixed on the reflecting plate 2; To block a shot at last and 1 be fixed on the reflecting plate 2 (lower end of block 1 closely is fixed on the corresponding metal reflecting plate 2 through screw 8) through screw 8; Constitute strip line radio-frequency unit 4 encapsulating structures, can accomplish installation process.
Concrete assembling process is removable to be divided into following step and to accomplish: the first step is installed in media supports 3 and strip line radio-frequency unit 4 on the reflecting plate 2; Second step will block a shot and 1 buckled on strip line radio-frequency unit 4, and media supports 3 is stretched out block 1 outside simultaneously, plays support and positioning action; The screw 20 that the 3rd step adopted screw to pass reflecting plate 2 locks with the screw 10 of block 1 mutually, makes block 1 and reflecting plate 2 fastening installations; The 4th step was the welding of external radio frequency cable 7; Its inner wire is welded on the strip line radio-frequency unit 4; Outer conductor is welded in connectivity port 5 welding grooves of block 1, and the abutment wall 1s of block 1 does not take place directly to contact with reflecting plate 2 except that its contact site, keeps certain interval D＞0.After the assembled, this strip line radio-frequency unit 4 can be connected with the external radio frequency circuit through the radio frequency cable 7 that has welded.
Said strip line radio-frequency unit 4 can be power division network, high pass network, low-pass network, bandpass network, duplex network that strip line is made, close in the road network network any one; On the basis of these heterogeneous networks; The encapsulating structure that further combines the utility model; Get final product corresponding formation strip line power splitter, strip line high pass filter, strip line low pass filter, strip line band pass filter, strip line duplexer, strip line mixer; And these devices are referred to as strip line radio-frequency units 4, belong to the extension of the utility model strip line radio-frequency unit 4.
In sum, the strip line radio-frequency unit encapsulating structure of the utility model makes formed device have preferable passive intermodulation index owing to adopt block and reflecting plate to carry out a mode that contacts installation; And it is simple in structure; Be easy to assembling, economize material, help large-scale mass production.
Although the utility model only provides above embodiment; But; Those skilled in the art in conjunction with common practise, should be able to associate more embodiment after reading over this specification; But the spirit of the not unconventional the utility model claim of such embodiment any type ofly is equal to replacement or simple modification all should be regarded as by the included embodiment of the utility model.
