Abstract
The utility model provides a color TV remote controller, which is composed of a circuit board (1), an infrared signal receiving processor (2), and a common frequency section switch (3). The utility model not only adapts to the refitting of high-frequency head and non remote-controlled color TV of C type and B type, but also has convenient refitting; the line of the TV and the line of the remote controller do not need to be changed, and the refitting work can be completed only by inserting the plugs of the three input end into the corresponding sockets of the frequency section switch (3) according to the different model numbers of the high-frequency head of the refitted color TV; in addition, the utility model has simple structure, low cost, and convenient manufacture.
Description
The utility model relates to a kind of remote control of colour television set receiver.
At present, the remote control of colour television set receiver of being sold on the market that non-distance-type color television set is repacked into the distance type color television set only can adapt to the tuner of C model, if the color television set of Type B tuner is reequiped, will change the circuit of television set or the circuit of receiver of remote-control sytem, such change is very inconvenient, is very difficult to non-professional people.
The purpose of this utility model is to provide the circuit of a kind of circuit that need not change television set or receiver of remote-control sytem just the non-distance type colour TV of C type or Type B tuner can be repacked into the remote control of colour television set receiver of distance type colour TV.
The utility model is to constitute like this: it comprises wiring board (1), infrared signal receiving processor (2), infrared signal receiving processor (2) input signal to a general frequency range switch (3), general frequency range switch (3) is by Frequency Band Selection integrated circuit block IC, Type B tuner connector socket (4), C type tuner connector socket (5), diode D1, D2, resistance R 1～R3, gun stocks (6) is formed, three terminals BV are arranged on Type B tuner connector socket (4), BU, BS, three terminals BL are arranged on C type tuner connector socket (5), BU, BH, BV termination D1, the negative pole of D2, the positive pole of D1 connects 2 pin and the BL end of IC, the positive pole of D2 connects 7 pin and the BH end of IC, 6 pin of IC meet R1, R2, the end of R3, another termination BS end of R1, the BS end can directly not received R2 by R1 yet, between the R3, another termination power of R2, the end ground connection of R3, the terminals BU of two connector sockets connects 1 pin of IC, input 3 pin of IC connect the output of gun stocks (6), and 4 pin of the input of gun stocks and IC connect the output of infrared signal receiving processor (2).The different model of Gai Zhuan color television set tuner (7) upward or on the C type tuner connector socket (5) has just been finished repacking work as long as its three input plugs are inserted into corresponding Type B tuner connector socket (4) as required.
Compared with prior art, the utility model not only is adapted to the repacking of C type and Type B tuner color television set, and repacking is convenient, does not need the circuit of television set and the circuit of receiver of remote-control sytem are done any change, and the utility model is simple in structure, cheap, easy to make in addition.
Accompanying drawing 1 is a structural representation of the present utility model; Accompanying drawing 2 is electrical schematic diagrams of general frequency range switch of the present utility model (3).
Embodiment of the present utility model: infrared signal is connect processor (2) and general frequency range switch (3) is installed on the wiring board (1), wiring board (1) is installed in place suitable in the television cabin of being reequiped, general frequency range switch (3) is by Frequency Band Selection integrated circuit block IC, Type B tuner connector socket (4), C type tuner connector socket (5), diode D1, D2, resistance R 1～R3, gun stocks (6) is formed, triode of the available resistance of gun stocks (6) constitutes, three terminals BV are arranged on Type B tuner connector socket (4), BU, BS, three terminals BL are arranged on C type tuner connector socket (5), BU, BH, BV termination D1, the negative pole of D2, the positive pole of D1 connects 2 pin and the BL end of IC, the positive pole of D2 connects 7 pin and the BH end of IC, 6 pin of IC meet R1, R2, the end of R3, another termination BS end of R1, the BS end can directly not received R2 by R1 yet, between the R3, another termination power of R2, the end ground connection of R3, the terminals BU of two connector sockets connects 1 pin of IC, input 3 pin of IC connect the output of gun stocks (6), 4 pin of the input of gun stocks and IC connect the output of infrared signal receiving processor (2), the finished product of infrared signal receiving processor (2) for selling on the market, the IC model is M54573L, D1, the D2 model is CN4148, the resistance of resistance is R1:1K, R2:56K, R3:390K.
