Combined receiver for satellite television
The utility model relates to a kind of knockdown satellite television receiver.
At present satellite television receiver on the market all is that the unit list is used, the user watches in collective for communal antenna system or cable television network, promptly satellite television receiver can only transmit a program at one time, be connected on all television sets on this machine at one time, each user can only see an identical program, if want to change the TV programme of watching, just can only regulate satellite television receiver again, though changed the programme content of watching, but the spectators before video screen also can only see the program after the change, and can not be by the hobby of oneself, require to select the program that to watch, so just limit the possibility that the spectators that teleview select TV programme, given numerous spectators the profit that brings inconvenience.
In addition, the unit list improves with the waste that also causes equipment, cost.Just must use many cover television receivers if want to watch multiple programs, will cause the reliability of bulky other receiver also can descend like this.
The purpose of this utility model is for overcoming above-mentioned shortcoming, provide a kind of novelty, the same time can watch the combined type satellite television receivers of many cover TV programme.
The utility model is realized by following proposal:
The combined type satellite television receiver comprises casing, power transformer, adjuster, power splitter, unit circuit board receiver, and a plurality of unit circuit board receivers and a plurality of tuner are set in casing.
Circuit board in casing casing relatively is transversely arranged, or vertically arranges, again or between the circuit board up and down overlap mode arrange, also can be circuit board bottom surface (printed circuit face) relatively or the relative arrangement mode of one side of the element on the circuit board.
The shared cover power-supply system that only needs in casing is powered, and can save transformer and voltage stabilizing circuit common part expense like this, also can improve the reliability of machine simultaneously.
A plurality of integrated tuners are that overlapping or arranged side by side mode is arranged in casing.
Further specify the utility model below in conjunction with accompanying drawing:
Fig. 1 is the vertical view of the present unit list receiving satellite television receiver that uses.
Fig. 2 is the vertical view of first embodiment of satellite television receiver internal circuit board arrangement of the present utility model.
Fig. 3 is the vertical view of second embodiment of satellite television receiver internal circuit board arrangement of the present utility model.
Fig. 4 is the end view of the 3rd embodiment of satellite television receiver internal circuit board arrangement of the present utility model.
Fig. 1 is present satellite television receiver, uses this receiver can only transmit a programs at one time, can not satisfy the needs that different spectators select TV programme.
In Fig. 2, label 1 is the satellite television receiver shell, the 2nd, and circuit board receiver, the 3rd, power transformer and voltage stabilizing circuit plate, the 4th, integrated tuner, the 5th, power splitter, the 6th, tuning knob.In Fig. 1, circuit board is transversely arranged installation in casing.
Among Fig. 3, identical among the content that label is represented and Fig. 2, as can be seen, be vertically to arrange to install at casing interior circuit board 2.
Among Fig. 4, be that the upper-lower overlapping mode is installed at casing interior circuit board 2, circuit board 2 can be that two plate upper-lower overlappings that element is housed are arranged, also can be the circuit board bottom surface printed circuit face vis-a-vis installation or the one side of element arrange relatively.
The utility model can three independent receivers be combined into and arrange to be loaded in the machine.Also can four independent receivers be combined into and be installed in the machine.Present power splitter is only accomplished 4, if the allotment of power splitter increases, the utility model can also the more independent receiver of corresponding increase be combined into and be installed in the receiver.
A public power transformer-supplied can be saved transformer in receiver, saves electric power, saves material, can reduce cost simultaneously, improves reliability.
The utility model is if the combination of three independent receivers after promptly three programs of a satellite being received, is sent three programs, i.e. the function and the effect of suitable three the independent receivers of the receiver of a combination simultaneously.
Watch eight cover TV programme of satellite if desired, only need the receiver of two four unifications to get final product.Like this volume can to dwindle 75%(be that the volume of original 4 machines now only is the volume of a machine), cost can descend 40%, weight can reduce.
The utility model only need use the cable of an antenna, feed, tuner, a cover cable TV receiver, therefore cable can significantly reduce, except making the cable marshalling, also can reduce the generation of fault, the reliability of complete machine is improved greatly.
Compare with the independent receiver of present use, the utlity model has clearly superiority and practicality.
