Technical Field

The utility model belongs to the electronic communication field, in particular to two sets of four ways output frequency dividers of simple efficient, few, the use cost low, the convenient operation of use of wiring.

Background

In daily life, two or even a plurality of televisions are generally arranged in a home, and in order to receive ground wave signals and satellite wave signals by each television, a signal source needs to be mixed firstly, frequency division is carried out after frequency mixing, two groups of four-path signals are separated out by two distribution boxes after frequency division and are used by the two televisions, the mode of separating out the four-path signals by the distribution boxes after frequency division can meet certain use requirements, but the method also has the defects of more use of the two distribution boxes, more use parts, high use cost, poor use stability, higher failure rate, more trouble in wiring and incapability of effectively meeting the use requirements.

The to-be-solved technical problem of the utility model is to provide a need not to use the distribution box, use parts are few, use cost is low, the high fault rate of stability in use is low, the wiring is simpler, can effectively satisfy two sets of four ways output frequency divider of user demand.

SUMMERY OF THE UTILITY MODEL

Need to use two distributing boxes more, use the part many, use cost high, stability in use poor, the fault rate is higher, the wiring is more troublesome, can't effectively satisfy operation requirement scheduling problem for solving above-mentioned prior art, the utility model discloses a following technical scheme:

the utility model provides a two sets of four ways output frequency divider, include the receiving equipment who comprises ground ripples and satellite ripples signal source group, mixing subassembly, frequency division circuit and two receivable ground ripples and satellite ripples combined signal, signal source group and mixing subassembly signal intercommunication, the mixing subassembly passes through coaxial line signal intercommunication with the frequency division circuit, the equal signal intercommunication of frequency division circuit and two receiving equipment, two receiving equipment communicate with two external TV one-to-one signals respectively, the frequency division circuit is including leading to direct resistance AC inductance coil, distribution unit, first output unit and second output unit, first output unit, second output unit parallel connection are on the distribution unit, first output unit is including the first power supply unit, first high pass filter unit, first low pass filter unit and the three parallel connection for the antenna tuner power supply, second high pass filter unit, second low pass filter unit and the three parallel connection for the antenna tuner power supply.

The beneficial effects of the utility model reside in that: two sets of four-way signals are directly separated by the distribution unit in the frequency division circuit and used for two televisions, a distribution box is not needed, the number of used parts is small, the use cost is low, the use stability is high, the fault rate is low, the wiring is simpler, and the use requirements can be effectively met.
