Abstract
The utility model relates to a use novel plastic ulcerate source on Ku frequency channel tuner, characterized by: the feed source comprises a first assembly and a second assembly, wherein the first assembly comprises a shell and a plurality of annular first tooth-shaped structures arranged in the shell, the second assembly comprises a protruding head and a plurality of annular second tooth-shaped structures extending out of the head, the plurality of first tooth-shaped structures and the plurality of second tooth-shaped structures can be respectively meshed with each other, and the second assembly is arranged in the shell of the first assembly to form a feed source whole. The novel plastic bruising source of the utility model has light weight and low cost; a plastic waterproof cover can be omitted, the process is simple, and the cost is further reduced; in the finished product test stage of the Ku frequency band tuner, the plastic feed source is not installed, and the plastic feed source is installed after the test is completed, so that the size accuracy of the plastic feed source is only required to be ensured, and the inconvenience of the Ku frequency band tuner applying the aluminum alloy die-casting feed source in the finished product test is avoided.
Description
Technical field
The utility model relates to satellite broadcasting television and satellite communication technology field, especially a kind of routed source of plastic cement that is used in the novel separate design on the Ku frequency range tuner.
Background technology
At present, in satellite broadcasting television and satellite communication technology field, the Ku frequency range is that frequency range is preferentially used in International Telecommunications Union's regulation satellite television broadcasting, and Ku band frequency height, wavelength weak point, have the advantage that makes antenna miniaturization, help reducing cost, more help promoting, popularize and use.Therefore, satellite television broadcasting employing Ku frequency range is the inexorable trend of Future Development.Existing Ku frequency range satellite receives tuner and is made of feed and high frequency tuner circuit assembly.Wherein, feed is all made by aluminium alloy compression casting.There is following shortcoming in prior art: the first, and aluminum alloy die casting weight is big, and the difficult control of size, needs the artificial treatment burr, and die casting is bad or process bad entire body and need scrap problems such as melt back; The second, the feed of aluminium alloy compression casting needs assembling plastic cement waterproof cover in addition, not only increase cost and also increase assembling procedure, and the fluid sealant between plastic cement waterproof cover and Al-alloy parts seals when imperfect, also might cause leaking; The 3rd, the feed of aluminium alloy compression casting and this body by integral forming of aluminium alloy are in the stage of finished product test, the test fixture that needs collocation and feed equal angular, when the feed size of aluminium alloy has deviation slightly, in the time of just can causing testing noise by producing defective products, thereby cause waste.
The utility model content
At the deficiency of above existing Ku frequency range tuner feed, the purpose of this utility model provides the routed source of plastic cement of the novel separate design on a kind of Ku of being used in frequency range tuner.
The purpose of this utility model is achieved by the following technical solution: a kind of routed source of new type plastic that is used on the Ku frequency range tuner, it comprises first assembly and second assembly, first assembly comprises a shell and is arranged at first dentalation of a plurality of annulars in the shell, second assembly comprises that an outstanding head reaches second dentalation by the extended a plurality of annulars of this head, these a plurality of first dentalations and these a plurality of second dentalations can be meshing with each other respectively, and second assembly is fit in the shell of first assembly becomes a feed integral body.
As the utility model optimized technical scheme, when first assembly and second assembly were combined into feed integral body, the length of this feed was 35mm, and the width i.e. external diameter of the shell of first assembly is 28.3mm.
With respect to prior art, feed of the present utility model adopts and is separated into two-part plastic cement ejaculation parts be combined into, and in light weight, cost is low; And can save the plastics waterproofing lid, operation is simple, further reduces cost; Plastic cement penetrates feed to be separated with the aluminium alloy body, bad as the assembly or the aluminium alloy body quality of feed, only need replace bad parts, and need not whole tuner is scrapped; The Ku frequency range tuner of using plastic cement feed of the present utility model is when test, the plastic cement feed can be installed earlier, after test is finished the plastic cement feed is installed again, the size that only needs to guarantee the plastic cement feed accurately gets final product, and has avoided using the inconvenience of Ku frequency range tuner when finished product test of aluminium alloy compression casting feed.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is the perspective view after first assembly of the present utility model and second combination of components;
Fig. 2 is the generalized section after first assembly of the present utility model and second assembly and the combination of aluminium alloy body.
Embodiment
As shown in Figures 1 and 2, feed of the present utility model comprises that two are separated the assembly that plastic cement penetrates: first assembly 10 and second assembly 20.First assembly 10 comprises a shell 11 and is arranged at first dentalation 12 of a plurality of annulars in the shell, second assembly 20 comprises second dentalation 22 that an outstanding head 21 reaches by these head 21 extended a plurality of annulars, these a plurality of first dentalations 12 and these a plurality of second dentalations 22 can be meshing with each other respectively, after the engagement, second assembly 20 of feed is fit into first assembly 10, thereby in conjunction with as a whole.In Ku frequency range tuner, also have aluminium alloy body 30 with feed is installed together, it combines by buckle with the shell 11 of first assembly 10.
10 reflections of first assembly are from the signal of the diffusion of teledish, signal is concentrated as far as possible, utilize the characteristic of the penetrable plastic parts of radiofrequency signal that signal is passed to second assembly 20, utilize the minimum space between second assembly 20 and first assembly 10 to force signal to continue to transfer in the waveguide pipe (not shown) again.
When first assembly 10 of the present utility model and second assembly 20 were combined into feed integral body, the length of this feed was 35mm, and the width i.e. external diameter of the shell 11 of first assembly 10 is 28.3mm.Compared to the feed of the aluminium alloy compression casting of prior art, its weight reduces half.
When making the Ku frequency range tuner of using feed of the present utility model, earlier 30 die casting of aluminium alloy body are finished, populated circuit board then, the plastic cement that first assembly 10 and second assembly 20 are combined into penetrates feed and fits together plastic cement ejaculation feed and the 30 joint sealings of aluminium alloy body with aluminium alloy body 30 at last.
Test about Ku frequency range tuner, different with the test of prior art production line, use and just can test its received signal ability when when plastic cement of the present utility model penetrates the product development of Ku frequency range tuner of feed the plastic cement feed not being installed, after the reception signal is correct, follow-up as long as the size in the routed source of check plastics, the size match of its size and aluminium alloy body 30 and remaining design parameter are all accurate, and the Ku frequency range tuner finished product received signal after promptly plastic cement feed and circuit board, aluminium alloy body 30 etc. are partly assembled as can be known is accurate.
