Abstract
The utility model relates to a special purpose intelligent energy-saving power socket for a computer in the technical field of electrotechnics, characterized in that a control circuit is arranged between a special purpose jack of the computer of the socket and the other jacks. An intelligent chip is served as a core by the control circuit. The control circuit comprises a branch voltage and rectification circuit, an electric current sample circuit and a relay switch. Except the computer jack, electricity obtaining or electricity loss of each jack is controlled by attracting or disconnecting of the relay switch in the control circuit by each jack. The utility model realizes that the power supply of all the equipments on the socket is connected automatically when the computer is opened. The power supply of all the equipments on the socket is cut off automatically when the computer is shut down. Energy cost is greatly reduced in a state of stand-by. The utility model has an outstanding economical and social benefit.
Description
Technical field
The utility model relates to a kind of supply socket of electrical technology field, relates in particular to computer special intelligent energy-saving electric power socket.
Background technology
In general, computer and colour display screen have tens watts standby energy consumption under sleep state, even if shut down, as long as attaching plug does not also pull out, colour display screen has six in the same old way, seven watts standby energy consumption, as add sound equipment, printer is waited for the function consumption, then reach three, 40 watts, relevant department's investigation is thought, the average standby energy consumption of China's urban family is equivalent to the altar lamp that each household uses 15 watts to 30 watts, along with progressively popularizing of computer, the continuous development of the extensive use of office automation and networking, increasing product has had idle function, and the standby power consumption is a kind of energy waste, also influential useful life to product simultaneously, the consumer has also been increased financial burden.Supply socket on the existing market does not possess when booting computer and shutdown can start and cut off the function of other appliances power source on the socket automatically, if think energy-conservation, only when startup and shutdown, manually connect and close socket power, through understanding, it is to connect with relay coil by main frame that a kind of technical scheme is arranged, relay switch and other supply socket link, the main frame engage relay, and coil has electric current, then cause relay switch to be connected, other socket is connected.The shortcoming of sort circuit device is very unstable, than being easier to outage.Other has a kind of technical scheme is that this method cost is too high, is difficult for popularizing by the break-make of CPU control supply socket.
Summary of the invention
The purpose of this utility model is wasted energy consumption down at above-mentioned holding state, when not possessing booting computer and shutdown, socket can start and cut off the function of all the other load power sources on the socket and have now automatically, the relevant technologies scheme exists relevant not enough again, a kind of computer special intelligent energy-saving electric power socket is provided, automatically cut off the power supply of all the other each loads on the socket when being implemented in shut down of computer simultaneously, can connect the power supply of all the other each loads on the socket automatically again during booting computer.
The purpose of this utility model is achieved through the following technical solutions, a kind of computer special intelligent energy-saving electric power socket, comprise some groups of jacks in housing, the housing and the plug that connects through lead, it is characterized in that one group of jack in the housing is computer jack independently, the plug of connecting conducting wire and lead one end, all the other respectively organize the jack parallel connection, and being connected to what comprise level comparator and signal identification module between computer jack and each group jack in parallel is the control core circuit with the intelligent chip; Control circuit also comprises dividing potential drop and rectification circuit, current sampling circuit and relay switch; The source end of dividing potential drop and rectification circuit is in parallel with the computer jack, and its output voltage is for intelligent chip; Sample resistance in the current sampling circuit is serially connected in computer jack and 0 line of respectively organizing jack in parallel, the d. c. voltage signal that current sampling circuit produces connects the input of intelligent chip, the appliance switch coil is succeeded in the output of intelligent chip, and relay switch contacts is serially connected in the source end of respectively organizing the jack phase line in parallel.
The utility model is in the moment of computer connection, produce on the high-power resistance of electric current in sample circuit and exchange pressure drop, rectification by diode produces direct voltage, d. c. voltage signal is given 1 pin and 2 pin of intelligent chip LM324 in the control circuit, chip is by the height of decision level, determine that 6 pin output high level is to relay, the action of control relay, all jacks outside the computer jack are got, when shut down of computer is not worked, because of the sample circuit no signal, relay electric-loss, make all the jack dead electricity except that the computer jack, thereby made things convenient for computer user, avoided because of forgetting the standby energy waste of closing the load that patches on this socket that socket power causes and the reduction of service life of equipment, use the utility model, all electrical appliances on the socket, no longer need to pull out plug, realized that booting computer connects the power supply of all connecting devices automatically, computer is closed the power supply that cuts off all connecting devices automatically, the utility model greatly reduces the energy waste under the holding state, has remarkable economic efficiency and social benefit.
