Abstract
The utility model relates to a satellite signal receiver, which comprises a signal amplification down processing circuit unit and a case for collecting and guiding waves and containing the circuit unit. The casing is made of plastics, and the inner surface of the casing is coated with a metal thin film layer which can conduct microwave and prevent signal outleakage and outside noise. The metal thin film layer is made of conductive alloy material. Output singles of the processing circuit unit are output by a joint on a jack which is in screw connection on one surface on the casing and is coated with a metal thin film. The alloy material can be copper nickel alloy or kufil alloy or copper-gold alloy. The utility model has the advantages of low cost, convenient processing and long service life.
Description
The utility model relates to a kind of satellite-signal receiver, particularly a kind of low noise satellite-signal receiver, and its cost of manufacture is low, but can keep its original function.
Receiving satellite signal need wait by a wave collecting device, waveguide pipe, orthomode transducer and two low amplification receivers of noise and finish, and signal could be transferred to such as signal receivers such as television sets.But these equipment are because separation is far away, thereby the inconvenience use, and cost is also high.The applicant once released a kind of low noise satellite-signal receiver as shown in Figure 1, roughly comprise: a signal amplifies the continue waveguide pipe 12 of wave collecting device of down conversion process circuit unit (not shown), a signal output connector 14, a wave collecting device (horn) 11, of collecting microwave, and one continue waveguide pipe in order to holding the treatment circuit unit, and one prevents that microwave signal from leaking outside or by container 13 that the external world disturbed.Wherein, wave collecting device 11, waveguide pipe 12 and container 13 are integrally casting moulding and the metal shell that links together; In addition, be subjected to the erosion of outdoor climate to prevent it, outside metal shell, and coated, plastic casing 20 and separated into two parts 20a and 20b with a plastic casing 20 in order to protect this metal shell.In addition, screen with one usually and cover with plastic body (not shown) in the signal input port place above wave collecting device.
Yet, in the above-mentioned receiver manufacturing process, still must purchase the mould of metal shell and the mould of plastic casing respectively, and in assembling, necessary elder generation in metal shell, coats this metal shell with plastic casing with processing circuit unit again, the assembling trouble.
It is a kind of simple in structure that the purpose of this utility model is to provide, the low noise satellite-signal receiver that cost is low.
For the utility model that achieves the above object is taked following measure:
Satellite-signal receiver of the present utility model comprises:
One signal amplifies the down conversion process circuit unit; And
One has collection ripple, guided wave and ccontaining and coat this treatment circuit unit housing concurrently;
It is characterized in that: described housing is made of plastics, but its inner surface be coated with one deck conducting microwave and can prevent that stop signal leaks outside, and prevent the metal film layer that ambient noise disturbs.
Described satellite-signal receiver is characterized in that, described metal film layer is conductive alloy material.Described alloy material can be corronil or Kufil or copper-gold alloy.
Described satellite-signal receiver is characterized in that, the output signal of described treatment circuit unit is output by a joint that is bolted on the jack that a surface on the described housing also is coated with metallic film.
Compared with prior art, the utlity model has following effect:
Because housing of the present utility model is made of plastics, but and its inner surface be coated with one deck conducting filtering and can prevent that stop signal leaks outside, and prevent the metal film layer of ambient noise interference.So mould and assembly expenses are able to economization, but and also economization of the disbursement of material, thereby whole cost can reduce greatly.And, because the profile of plastic casing is easy to variation and control, and can be as conventional devices, between metal shell and plastic shell, form the space, thereby reduce the disrepair phenomenon except the intensity that can strengthen shell, also can many appearanceization and light and handyization, to adapt to different space requirements.
Reaching embodiment in conjunction with the accompanying drawings is described in detail as follows:
The accompanying drawing simple declaration:
Figure 1A, 1B, 1C are respectively the forward view and the left and right sides view of a known low noise satellite-signal receiver.
Fig. 2 represents the schematic cross-section of the receiver of a preferred embodiment of the present utility model.
Fig. 3 represents the schematic diagram of the receiver signal output part jack of the utility model preferred embodiment.
As shown in Figure 2, it is the schematic cross-section of low noise satellite-signal receiver of the present utility model.Satellite-signal receiver 1 comprises substantially: a signal amplifies down conversion process circuit unit 40; One wave collecting device 11; One waveguide pipe 12; Container 13 of one ccontaining and coating circuit unit etc.Wherein, wave collecting device 11, waveguide pipe 12 and container 13 are made of plastics, and ABS etc. for example one-body moldedly becomes same housing 10; Also be coated with layer of metal film 31 at housing 10 inner surfaces, metallic film 31 can be corronil, Kufil, copper-gold alloy etc. comprehensively.For ease of for the purpose of the assembling, container 13 partly also comprises a bottom 13a again, and to pack into behind the container 13 will being loaded with circuit board group that low noise amplifies down conversion process unit 40,13a is sealed with bottom, and reaches the function that coats and prevent to disturb.In addition, between circuit board and bottom 13a and be provided with a sept 50, to avoid short circuit.
As shown in Figure 3, one is positioned at the signal output plughole 14 on the container 13, has an internal thread, and also is coated with layer of metal film (not shown) equally on internal thread, or one-body molded the metallic conduction cover that inserts, for as shown in Figure 1 the out splice going splice 14 that is spirally connected.Wherein, the output of out splice going splice 14 is electrically connected with processing unit 40 again, and the signal handled output power supply such as is looked at use.
The making of metal coating 31, available any known film plating process is finished, and can in this plastic casing, infiltrate a certain amount of ultraviolet screener and antioxidant earlier, plate the layer of metal film more thereon, but this film must be a kind of material that can the conducting microwave, copper nickel etc. for example, and its ratio can be selected arbitrarily, its conductance is preferably in per square inch in the scope below 2 ohm, to reach the specification demand of high-frequency microwave.
Receiver of the present utility model, owing to can exempt the manufacturing of metal shell, so escapable cost; And plated film can be finished under suitable environment, because plastic casing is shock-resistant, corrosion-resistant, and can have certain intensity, thereby can be durable in use.
Though more than explain and unrestricted protection range of the present utility model with a preferred embodiment.
