Description
Affiliated technical field
The utility model relates to a kind of television set, particularly a kind of television set with controlled alternating current power supply output socket.
Background technology
At present, in the prior art, with power consumption equipments such as the matching used antenna amplifier antennafire of television set, satellite receiver, power amplifiers, in use, its power supply need be distinguished unlatching separately, when closing television electromechanics source, the power supply of power consumption equipments such as antenna amplifier antennafire, steering gear, satellite receiver, power amplifier also needs to close separately respectively, makes troubles to use.After finishing watching TV, some user only utilizes the dynamo-electric source of remote controller closing television, and the power supply of the power consumption equipments such as not closing antenna amplifier antennafire, steering gear, satellite receiver, power amplifier that do not want to take the trouble, make power consumption equipments such as antenna amplifier antennafire, steering gear, satellite receiver, power amplifier be in electriferous state for a long time, so not only waste electric energy, also may bring potential safety hazard.
Summary of the invention
Can not the control antenna amplifier for overcoming television set in the prior art, the shortcoming that opens and closes of appliances power sources such as steering gear, satellite receiver, power amplifier, the utility model provides a kind of television set with controlled alternating current power supply output socket, this television set is when start, can open the power supply of television set match appliances such as antenna amplifier antennafire, satellite receiver, power amplifier automatically, when television set shuts down, can close the power supply of television set match appliances such as antenna amplifier antennafire, satellite receiver, power amplifier automatically.The technical scheme that its technical problem that solves the utility model adopts is: a kind of television set with controlled alternating current power supply output socket, comprise housing of TV set, display screen and television set circuitry, wherein power circuit part is divided into: attaching plug is connected by lead and mains switch and controlled switching power circuit thereof, housing of TV set is provided with alternating current power supply output socket, alternating current power supply output socket is connected with external power supply through control circuit, and control circuit is electrically connected with switching power circuit.Be provided with the relay of control alternating current power supply output socket and external power supply break-make in the control circuit, the coil of relay is connected with switching power circuit, and the normally open contact of relay is connected with alternating current power supply output socket.Be connected in parallel to hand switch with the contact of relay.Relay is the single channel control relay, or the two-way control relay.Hand switch is single-pole single-throw switch (SPST) or double-pole single throw.Be connected in series with current-limiting resistance and indicator light between the live wire of AC power out-put supply socket and the zero line.
The beneficial effects of the utility model are, substantially do not increasing on the basis of television set manufacturing cost, make and the matching used antenna amplifier antennafire of television set, steering gear, satellite receiver, electrical appliances such as power amplifier, alternating current power supply output socket on the use television set is as power supply, when television set is opened or is closed, the break-make of power supply in the control alternating current power supply output socket, make other television set match appliances open or close, be user-friendly to, saves energy is eliminated because antenna amplifier antennafire, steering gear, satellite receiver, the long-time charged and potential safety hazard brought such as power amplifier.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the circuit theory diagrams of the utility model embodiment one.
Fig. 2 is the circuit theory diagrams of the utility model embodiment two.
Among the figure, 1 attaching plug, 2 leads, 3 mains switches, 4 switching power circuits, 5 relays, 6 hand switches, 7 current-limiting resistances, 8LED indicator light, 9 alternating current power supply output sockets.
Embodiment:
Referring to accompanying drawing, TV set power plug 1 of the present utility model is connected through lead 2 and mains switch 3 and controlled switching power circuit 4 thereof, a dc voltage output end of switching power circuit 4 is electrically connected with the coil of relay 5, this output has voltage output when the television set operate as normal, this output no-voltage output when TV remote-control shutdown or mains switch 3 disconnect, tv shell is provided with alternating current power supply output socket 9, alternating current power supply output socket 9 is connected on the normally open contact of relay 5, alternating current power supply output socket 9 is connected with external power supply by the normally open contact of relay 5, the on/off of relay 5 control alternating current power supply output sockets 9.When the television boot-strap operate as normal, switching power circuit 4 has direct voltage to export to the coil of relay 5, the closing of contact of relay 5, alternating current power supply output socket 9 has alternating voltage output, when TV remote-control shutdown or mains switch 3 disconnections, switching power circuit 4 no direct voltages are exported to the coil of relay 5, and the contact of relay 5 disconnects, alternating current power supply output socket 9 no alternating voltage outputs.The normally opened contact of relay 5 hand switch 6 that is connected in parallel, when hand switch 6 disconnected, the control that opened and closed by relay 5 was during hand switch 6 closures, alternating current power supply output socket 9 is charged all the time, is not subjected to the control of the switching of relay 5.Usually under the state, hand switch 6 is in off-state.Be connected in series with a current-limiting resistance 7 and indicator light 8 between the zero line of alternating current power supply output socket 9 and the live wire, in the alternating current power supply output socket 9 when charged, indicator light 8 is luminous, when alternating current power supply output socket 9 is not charged, indicator light 8 is not luminous, and whether the user is known in the alternating current power supply output socket 9 easily charged.
