Description
Technical field
The utility model relates to technical field of television sets, particularly relates to a kind of detachable TV tuner.
Background technology
The main TV broadcasting system used has PAL, NTSC, SECAM tri-kinds in the world, and most of China area uses pal mode, and Japan, Korea S and the American-European countries such as south east asia and the U.S. use TSC-system formula, and Russia then uses Sequential Color and Memory system formula.The DV product of the formal entry that China market has been bought is all pal mode.Tuner: being that television set is used for receiving high-frequency signal and a kind of device demodulating video information, is also the Part I of public passage.The tuner that current television set uses, as the tuner of television set, is generally divided into digital signal tuner and analog signal tuner, for the tuning of received television signal and high-frequency signal amplifier, and satellite television decoder.Tuner for harmonic ringing is integrated on TV set circuit main board or by tuner and is welded on mainboard by existing TV set circuit main board substantially, tuner and mainboard can be made to operate as a product, substantially bundle, mainboard can not support the tuner of number of different types simultaneously, and when tuner goes wrong, change also cumbersome.And because television set is because of the different tuner of various countries' television system difference matching, television set sales region is restricted.
Utility model content
The purpose of this utility model is for above weak point, provides a kind of detachable TV tuner, realizes configuring different tuners, convenient disassembly according to the television set of different sales region, simple and practical.
The scheme that the utility model technical solution problem adopts is a kind of detachable TV tuner, comprise TV SKD circuit and the more than one tuner for accepting digital satellite, surface wave, cable television signal, end face on described tuner is provided with numerical digit input and analogy input, the bottom surface of described tuner is provided with row's pin plug, and corresponding to the described row's pin plug respectively row's pin of described numerical digit input and analogy input is electrically connected; It is female that one lateral edges of described TV SKD circuit is provided with the row matched with tuner, and described row mother is electrically connected with described row's pin plug.
Further, described tuner surrounding is also laid with several for being fixed on the tapped through hole on described TV SKD circuit.
Further, described row's pin plug is positioned at a lateral edges of described tuner bottom surface.
Further, described TV SKD circuit is provided with the mounting groove matched with described tuner.
Compared with prior art, the utility model has following beneficial effect: described tuner can independent packaging, selects different tuners freely to arrange in pairs or groups as apolegamy part according to television set sales region; Described adjuster is coordinated with the row mother be positioned on described TV SKD circuit by described row's pin plug simultaneously, convenient disassembly, and compatible strong.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figures 1 to 3, the detachable TV tuner of one of the present embodiment, comprise TV SKD circuit and the more than one tuner 1 for accepting digital satellite, surface wave, cable television signal, the end face of described tuner 1 is provided with the numerical digit input 2 for inputting DVB-T signal and the analogy input 3 for inputting anolog TV signals, the bottom surface of described tuner is provided with row's pin plug 7, and corresponding to the described row's pin plug 7 respectively row's pin 8 of described numerical digit input 2 and analogy input 3 is electrically connected; It is female that one lateral edges of described TV SKD circuit is provided with the row matched with tuner, and described row mother is electrically connected with described row's pin plug 7.
From the foregoing, the beneficial effects of the utility model are: described tuner 1 can independent packaging, select different tuners 1 freely to arrange in pairs or groups as apolegamy part according to television set sales region; Described adjuster 1 convenient disassembly simultaneously, and compatible strong.
In the present embodiment, described tuner 1 surrounding is also laid with several for being fixed on the tapped through hole 6 on described TV SKD circuit.Adopt bolt to screw in tapped through hole 6 described harmony device 1 is fixed in described TV SKD circuit.
In the present embodiment, described row's pin plug 7 is positioned at a lateral edges of described tuner 1 bottom surface.Better can arrange female cooperation with described.
In the present embodiment, described TV SKD circuit is provided with the mounting groove matched with described tuner 1.By being fixed in mounting groove by tuner 1, make TV SKD circuit more attractive in appearance.
In sum, the detachable TV tuner of the one that the utility model provides, not only can independent packaging, selects different tuners freely to arrange in pairs or groups as apolegamy part according to television set sales region; Described adjuster convenient disassembly simultaneously, and compatible strong.
Above-listed preferred embodiment; the purpose of this utility model, technical scheme and advantage are further described; be understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
