Description
The utility model is the whole shutdown units of a kind of remote control of colour television set.
The remote control of existing color television set can only realize that remote control partly shuts down, main circuit that promptly can only the telecontrolled cut colour TV, the remote control circuit in can not the telecontrolled cut colour TV.If realize all shutdown, still need and directly press the mains switch of colour TV, or dial attaching plug down, make troubles for user's use; If untimely cutting off the electricity supply not only wasted electric energy, and shortened the life-span of this partial circuit of colour TV.
Have a kind of mode that adopts electromagnet to drag mains switch to realize remote-control closedown in the prior art, its shortcoming is that this mechanism's volume is big, machinery noise is big, cost is high, and various types of colour TVs can not be general.
The purpose of this utility model is to provide a kind of easy to use, saves energy, prolongation colour TV useful life, cost is low and can the general whole shutdown units of remote control of colour television set of all kinds of colour TVs.
The purpose of this utility model is realized by following technical scheme.
The whole shutdown units of a kind of remote control of colour television set, its special character is at the housing internal fixation of colour TV the box body of being made up of housing (1), support (2) is arranged, support (2) at box body is gone up fixed printed circuit board (3), on printed circuit board (PCB) (3) diode D is installed

3And capacitor C
1The monostable of forming triggers (5), and No. 2 pin of the timer IC of monostable flipflop (5) are connected with OR circuit (4); Relay J is actuator (6), and the coil of relay J is connected the normally opened contact K of relay J with No. 3 pin of the timer IC of the positive pole of power supply and monostable flipflop (5)
2Button K is often opened in the start that is connected in parallel on colour TV with lead
1On.
The timer IC of described monostable flipflop (5) is 555 serial integrated circuits.
The course of work of the whole shutdown units of remote control of colour television set of the present utility model is
When button K is often opened in the start of pressing colour TV
1The time, the remote control circuit in the colour TV is by the diode D of OR circuit (4)
1, or D
2, or D
3Export high level, make No. 3 pin output low levels of the timer IC of monostable flipflop (5), drive the relay J work of actuator (6), its normally opened contact K
2Connect.This moment, button K was often opened in the start of colour TV
1Disconnect, because the self-locking action of relay J, remote control circuit (7) and main circuit (8) in the colour TV work on.
Remote-control closedown can carry out in two steps, and first step shutdown is the remote-control closedown of colour TV prior art.When the needs colour TV shuts down rest during a period of time, click the switch for the treatment of on the remote controller, colour TV remote control circuit output signal, driving switch K
3Turn-off colour TV main circuit (8).Under this state, as long as click arbitrary numerical key on the remote controller, colour TV can be resumed work; The second step shutdown is that remote control provided by the utility model is all shut down, promptly on the basis of first step shutdown, by treating switch to three second that the colour TV remote control circuit is by the D of OR circuit (4) on the remote controller
1Or D
2Or D
3Output low level, through the time-delay of the timer IC of monostable flipflop (5) circuit, from No. 3 pin output high level, the relay J of actuator (6) quits work, normally opened contact K
2Turn-off remote control circuit (7) and main circuit (8) in the colour TV, thereby realize all purposes of shutdown of colour TV remote control.
The whole shutdown units of colour TV remote control of the present utility model are compared with existing part remote-control closedown device, have simple to operate, easy to use, saves energy, and can prolong advantage such as colour TV useful life; The whole shutdown units that drag the mains switch mode with existing electromagnet are compared, owing to adopt 555 serial integrated circuits as components and parts such as timer and employing universal miniature relays, have advantages such as volume is little, machinery noise is little, cost is low, applied widely
Utilize an embodiment shown in the drawings below, the utility model is described in further detail.
Accompanying drawing 1 is the whole shutdown unit structural representations of remote control of colour television set.
Accompanying drawing 2 is A-A cross-sectional schematic in the accompanying drawing 1.
Accompanying drawing 3 is electrical schematic diagrams of this device.
Accompanying drawing 4 is that this device is installed on schematic diagram in the colour TV housing.
With reference to attached Fig. 1 and 2, box body is made up of metal shell (1) and support (2).
With reference to accompanying drawing 1,2 and 3, actuator (6) selects 12V universal miniature relay J for use, and its D.C. resistance is 300～400 Ω, and its power consumption is about 30～40mA; D
