The power supply socket on the socket box comprises a main and a slave group; the working condition of the electric appliance on the main power supply socket group (1) is monitored through a conversion/ detection circuit (2); an execution circuit (4) controls the slave power supply socket group (3) to be mutually connected or disconnected with the power supply input terminal; accordingly, the purpose that when the main electric appliance is in the working state, the power supply of the slave appliance is automatically switched on, and when the main electric appliance is out of the working state, the power supply of the slave electric appliance is automatically switched off is achieved; convenience is brought for the user to use, and the electric charge is saved for the user; the utility model is suitable for the computer system, the domestic acoustic image system, and the similar occasions.
Description
Affiliated technical field
The utility model belongs to family expenses and similar applications appliance field, relates to a kind of desk side computer system or other similar combined power socket box that requires the electric system distribution given.
Background technology
Present known combined power socket box has no relation between its each socket.This socket box is used for master-slave mode electricity consumption occasion (ancillary equipment such as television set and DVD player, VCD machine, video tape recorder, karaoke machine for example, ancillary equipment such as CD player and equalizer, power amplifier, audio amplifier, ancillary equipment such as the main frame of computer and display, printer, scanner) time, each is powered simultaneously with a socket on same socket box for main equipment and slave unit often.This method causes convenient and power saving can not take into account, and seems unreasonable.On the one hand, the own power supply of incomplete cut-off usually when main equipment is not worked, but be in " wait " state, with conveniently start, convenient work.On the other hand, slave unit can't not play a role naturally when main equipment was not worked, but present many slave units are not cut off the electricity supply when not working for easy to operate yet.The electric energy of slave unit consumption can not saved when obviously, main equipment was not worked.Electrical Appliances Designing at present trends towards simplified control, above the equipment that has in addition do not have can power cutoff switch (for example some display, printer, DVD player or the like): as long as coherent signal one, it enters operating state at once, and it just is in energising " wait " state always when not working.Because most family expenses or similar electric system are not 24 hours every days, annual uninterrupted the use, no-load ratio is generally very high; An electric equipment wait state though to waste electrical power little, if be not related to the whole year, add up this waste electric just considerable.Under the present circumstances, no power when wanting to allow this type of electric equipment not work is pulled up its power-line plug maybe from socket when unless used the switch of this socket correspondence is turned off.Like this whenever need not just pull out one by one or close one by one, whenever will be with just inserting one by one or opening one by one, obviously very inconvenient; Can certainly be with the whole cut-out of socket box power supply reaching purpose of saving, but this just cut off the power supply of main equipment simultaneously, against original intention easy to use.
Summary of the invention
The purpose of this utility model is to provide a kind of modified model master-slave mode combined power socket box, make when having only main electrical appliance above being inserted in running order, be inserted in and top just obtain the power supply supply automatically, to reach not only convenient but also purpose of power saving from electrical appliance.
The technical scheme that its technical problem that solves the utility model adopts is: comprise main power supply base group in insulation crust, from power supply base group, conversion/testing circuit, executive circuit, two socket groups all are made up of one or several socket.It is characterized in that: main power supply base group links by conversion/testing circuit and power input; The output of conversion/testing circuit links to each other with executive circuit, links from the output and the power input of power supply base group by executive circuit.This moment is as long as power input has electricity, main power supply base group just to have; But have only when the electrical appliance on the main power supply base group enters operating state, operating current greater than rated value, this electric current makes from power supply base group and power input through conversion/testing circuit, executive circuit and links, and just can obtain the power supply supply from the power supply base group.
For preventing on the main power supply base group that super-high-current damages subsequent conditioning circuit, can the parallel voltage-stabilizing protective circuit on conversion/testing circuit or executive circuit, make the voltage that is applied on the executive circuit be unlikely to too high all the time; For make main electrical appliance be in wait state, executive circuit is unlikely to move in advance when having small amount of current to flow through conversion/testing circuit, can be on conversion/testing circuit shunt circuit in parallel, executive circuit just moves when making only in running order when main electrical appliance, as to flow through conversion/testing circuit electric current greater than rated value; For avoiding executive circuit because of the ripple voltage misoperation, can be at the input of executive circuit filter circuit in parallel.More than each electronic circuit can distinguish according to actual needs or all insert.
The beneficial effects of the utility model are: have only when the electrical appliance on the main power supply base group enters operating state, the electrical appliance on the power supply base group just can obtain the power supply supply; In case main electrical appliance is deactivated state, be in and wait for or halted state, just be cut off from the power supply of electrical appliance.Both keep the original ease of use of electric equipment system thus, reached the purpose of economize on electricity again.
