Description
Technical field
The utility model relates to a kind of novel isolation lid, belongs to satellite receiver, satellite frequency demultiplier, tuner field.
Background technology
With clutter or harmonic wave in satellite frequency demultiplier carrier wave; The frequency-doubled signal and extraneous signal etc. of local oscillator these all can produce interference signal.The three elements that interference signal produces are interference source, responsive source and coupling path, and these three elements lack one, and interference problem all can not exist.General interference source and responsive source can not solve, and normally try every possible means from coupling path, are also the most frequently used methods.As added shielding isolation, adding means such as inhaling ripple material suction ripple.
Process now conventional isolation and absorption two kinds of processing modes for interference signal:
Isolation technology: the isolation lid adopting metal material to make must closely with being engaged of ground, be unfavorable for that assembling is produced, interference signal is gone here and there confined space meeting is mutual, well can not eliminate interference.
Absorption techniques: adopt the process of inhaling ripple blob of viscose and conducting foam, Charges is artificial, high cost, inhales the harmful effects such as ripple Hou Hui Hair Hot.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of novel isolation lid utilizing aerial array operation principle effectively to eliminate interference signal, save suction ripple blob of viscose and conducting foam use.
The utility model is achieved through the following technical solutions: the novel isolation lid of one of the present utility model, comprise body casing, pcb board is installed in the upper end of this body casing, the upper end of described pcb board is provided with metal insulated cover, described pcb board and metal insulated cover are installed in body casing, described metal insulated cover is provided with isolated vias, isolated vias is provided with more than one, its spread geometry is the arrangement of equilateral triangle form, the centre being positioned at isolated vias is interted and is provided with the insulated column identical with isolated vias quantity, described insulated column spread geometry is the arrangement of equilateral triangle form, isolation shell of column is formed between every two insulated columns, isolated vias section is formed between every two isolated vias.
Last night preferred technical scheme, described isolated vias and insulated column on metal insulated cover in arrayed.
The beneficial effects of the utility model are: the utility model can eliminate the destructive interference signal in direction, four sides, only need carry out absorption process for the sputtering interference signal of above-below direction, reduce conducting foam and inhale ripple blob of viscose, cost-saving, tight seal is not needed to isolate, the real formula of assembling just, is beneficial to production, effectively eliminates destructive interference signal.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is overall package schematic diagram of the present utility model;
Fig. 3 is the utility model interference signal schematic diagram.
Embodiment
All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this specification (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
As depicted in figs. 1 and 2, the novel isolation lid of one of the present utility model, comprise body casing 23, pcb board 22 is installed in the upper end of this body casing 23, the upper end of described pcb board 22 is provided with metal insulated cover 21, described pcb board 22 and metal isolation lid 21 plate are installed in body casing 23, described metal insulated cover 21 is provided with isolated vias 12, isolated vias 12 is provided with more than one, its spread geometry is the arrangement of equilateral triangle form, the centre being positioned at isolated vias 12 is interted and is provided with the insulated column 11 identical with isolated vias 12 quantity, described insulated column spread geometry is the arrangement of equilateral triangle form, isolation shell of column 100 is formed between every two insulated columns, isolated vias section 200 is formed between every two isolated vias.
As preferred embodiment, isolated vias and insulated column are arrayed on metal insulated cover.
Utilize metal insulated cover of the present utility model, pcb board and body casing in Fig. 2, after assembling is joined in fact, effectively can shield isolation and eliminate LNB interference signal, and ease of assembly is produced, cost-saving.
As shown in Figure 3, this array way, is superposed by the electromagnetic wave signal of 180 degree of phase differences, and the destructive interference signal in 31,32,33,34 directions in Fig. 3 is eliminated, and in Fig. 3, the sputtering interference signal in 35,36 directions can not be eliminated.
The beneficial effects of the utility model are: the utility model can eliminate the destructive interference signal in direction, four sides, only need carry out absorption process for the sputtering interference signal of above-below direction, reduce conducting foam and inhale ripple blob of viscose, cost-saving, tight seal is not needed to isolate, the real formula of assembling just, is beneficial to production, effectively eliminates destructive interference signal.
The above, be only embodiment of the present utility model, but protection range of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection range of the present utility model.Therefore, the protection range that protection range of the present utility model should limit with claims is as the criterion.
