By arranging the digital television tuning chip in the seat body, the vacant space in the seat body is used, the volume occupied by a tuner is saved, a space does not need to be reserved for the tuner when a terminal product is designed, and the volume of the terminal product with a digital television reception function can be greatly reduced.
Description
Technical field
The present invention relates to a kind of connector, be specifically related to a kind of connector that has tuning circuit.
Background technology
In recent years, along with popularizing of DTV and TV set-top box, the demand of digital TV tuner increases day by day, and along with the raising of consumer demand, digital TV in high resolution machine and STB also just develop towards lighter and thinner direction simultaneously.Very big of traditional digital TV tuner volume reduced liquid crystal TV set thickness for television set production firm and brought difficulty, is unfavorable for that also STB production firm dwindles the size of mainboard.Fig. 1 is that traditional connector is connected sketch map with tuner, and wherein 10 is the connector of connector, and 18 is the pedestal of connector, mainly plays fixing and shielded signal effect; 13 is tuner, and 11 is the circuit board of tuner, and 12 is the signal input core of connector, and 14 is row's pin of tuner; 15 is the orientation angle of tuner, and 16 is TV SKD, and 17 is the holding wire plug, by seeing among the figure; Part in the pedestal is vacant basically, and tuner is bulky, has taken more space.
Summary of the invention
The purpose of this invention is to provide a kind of connector that has tuner function, tuning circuit is built in the connector, saved the shared volume of tuner.
For realizing above-mentioned purpose, the present invention has adopted following technical scheme: the present invention includes connector, pedestal, also comprise being arranged at the inner printed circuit board (PCB) of pedestal, be provided with the DTV tuning chip in the printed circuit board (PCB).
Can know by technique scheme; The DTV tuning chip is arranged at pedestal inside; Utilized the inner vacant space of pedestal; Saved the shared volume of tuner, when end product designs, need not to be the tuner headspace, can greatly reduce volume with the end product of DTV receiving function.
Description of drawings
Fig. 1 is that the connector of prior art is connected sketch map with tuner;
Fig. 2 is the cutaway view of one embodiment of the present of invention;
Fig. 3 is the cutaway view of one embodiment of the present of invention.
Embodiment
Like Fig. 2, shown in Figure 3, the present invention includes connector 1, pedestal 2, orientation angle 6, also comprise the printed circuit board (PCB) 5 that is arranged at pedestal 2 inside, be provided with the DTV tuning chip in the printed circuit board (PCB) 5.
The DTV tuning chip is arranged at originally vacant pedestal 2 inside; Utilized the inner vacant space of pedestal; Saved the shared volume of tuner, when end product designs, need not to be the tuner headspace, can greatly reduce volume with the end product of DTV receiving function.
Also be provided with the digital-TV channel demodulation chip in the described printed circuit board (PCB) 5, also be provided with the digital television signal decoding chip in the described printed circuit board (PCB) 5.
Most in the market digital TV tuner does not possess the demodulation code function; Its rear end needs the demodulation decoding circuit could normally export sound, vision signal, and this has just increased the multifunction electronic Products Development difficulty and the development time of DTV receiving function.
The present invention is integrated in pedestal 2 inside with DTV tuning chip, digital-TV channel demodulation chip and digital television signal decoding chip; Thereby form a complete digital TV receiver group; Direct outputting video signal and audio signal; End product only need carry out software control to tuning chip through the tuning chip control interface; Can realize the reception of DTV, reduce the development difficulty and the development time of subsequent development, also further reduce the volume of the end product of band DTV receiving function simultaneously.
What printed circuit board (PCB) 5 adopted is the two-sided multi-layer sheet that mounts; Wherein top layer and bottom are placed IC and other components and parts, and top layer promptly connects first side towards pedestal 2 inside, and bottom is towards pedestal 2 outside machine TV SKD one sides; Said DTV tuning chip is positioned at top layer; The second layer is the stratum, and the 3rd layer is bus plane, and the 4th layer is signals layer.Demodulation chip is positioned at top layer, and decoding chip is positioned at bottom.
Like Fig. 2, shown in Figure 3, the bottom surface of described pedestal 2 is embedded with double row's pin 3, and described printed circuit board (PCB) 5 is vertically fixed between the two row row pins of double row's pin 3.Signal input core 4 is drawn the signal input port of vertical insertion printed circuit board (PCB) 5 in the connector 1.Pad on the printed circuit board (PCB) 5 links to each other with corresponding row's pin.
As shown in Figure 2, described double row's pin 3 is a vertical bar shape row pin, the outside of syringe needle directed in orthogonal direction and sensing pedestal 2.This mode is suitable for horizontal mounting means, and 7 is TV SKD.
As shown in Figure 3, described double row's pin 3 is bending strip row pin, and syringe needle points to horizontal direction and points to the outside of pedestal 2.This mode is suitable for vertical mounting means, and 7 is TV SKD.
Described double row's pin 3 is totally 12 pins, and the spacing of double row's pin 3 row's pins is 1mm.
Such row's pin design is except the effect with communications signals; Also have and strengthen printed circuit board (PCB) 5 and the fixing effect of television main, and can replace an orientation angle 6, make original angle be reduced to 3 by 4; And do not reduce the intensity that connects, improved installation effectiveness.
This tuner can be realized various types of DTVs, comprises satellite digital TV, terrestrial DTV, cable digital TV, mobile digital TV, digital analog integrated reception.
Below in conjunction with Fig. 2, Fig. 3 brief description operation principle of the present invention; 8 is the holding wire connector; The holding wire connector is with after the connector of this connector is connected, the tuning circuit part that digital television signal gets into printed circuit board (PCB)s 5 through the input of the signal in this connector connector 1 core 4, and tuning chip is tuned as intermediate-freuqncy signal with the radiofrequency signal of input; Intermediate-freuqncy signal gets into channel demodulation circuit; Through channel demodulation output TS stream signal, TS stream signal gets into decoding circuit at last and decodes, decoding back outputting video signal and audio signal.
