Description
Technical field
The utility model relates to a kind of power supply switch controller, but a kind of master-slave mode electric outlet of delay switching-off specifically.
Background technology
The structure of existing a kind of master-slave mode electric outlet is on the market: connect plate by attaching plug by power line, be provided with main output plughole and secondary output plughole on plate; Main output plughole is serially connected on the major loop of supply socket.The input termination master output plughole of sample circuit, it exports relay termination, and secondary output plughole serial connection relay switch is attempted by on the major loop.On major loop and be connected to and be sample circuit and relay direct current power source supplying power circuit.This master-slave mode electric outlet is by the sampling of sample circuit to the electric current of main output plughole place circuit, makes relay or discharge relay switch according to the big or small adhesive of the load of main output plughole.Relay adhesive relay switch when load reaches certain value to secondary output plughole power supply, makes the electric operation on the secondary output plughole; When sample circuit detects the non-loaded or load of main output plughole when too small, relay discharges relay switch, disconnects the power supply to secondary output plughole, and the electrical equipment on the secondary output plughole cuts out.This master-slave mode electric outlet is under the idle situation of equipment (main equipment) that main output plughole connected, and the equipment that secondary output plughole connected (slave unit) is not then powered; Have only when main equipment is worked, slave unit just obtains power supply and enters operating state, solves the electric weight waste that the slave unit continuous service causes when the main equipment standby with this.The weak point of above-mentioned master-slave mode electric outlet is: the one, and the power supply of main equipment needs Artificial Control when closing, can't realize closing automatically, causes and uses inconvenience; The 2nd, forget that the user when closing general supply, main equipment is in holding state for a long time, and the main equipment that is in holding state will cause waste of energy and equipment loss so still in power consumption, also can reduce service life of equipment.
The utility model content
But the purpose of this utility model just provides the master-slave mode electric outlet of the delay switching-off of a kind of not only convenient but also power saving, to increase the dependability and the useful life of electrical equipment.
The utility model is achieved in that by attaching plug and connects plate by power line, is provided with main output plughole CZ1 and secondary output plughole CZ2 on plate; Main output plughole CZ1 is serially connected on the major loop of supply socket; The input termination master output plughole CZ1 of sample circuit, its output relay termination J2; Be attempted by on the major loop behind the secondary output plughole CZ2 serial connection relay switch JK2; On major loop and be connected to and be sample circuit and relay J 2 direct current power source supplying power circuit, its key points in design is that the output of DC power supply circuit connects delay circuit, electrical equipment J1 is succeeded in the output of delay circuit, the output of sample circuit is connected on the input of delay circuit through feedback circuit, and the relay switch JK1 that is connected in parallel on starting switch K two ends is connected on the input of major loop.
After adopting such structure, press starting switch K, the AC power of 220V obtains low-voltage DC after DC power supply circuit step-down, rectification, voltage stabilizing, filtering, relay J 1 energising adhesive, and the closed conducting of relay switch JK1 is main output plughole CZ1 power supply.Because at this moment the effect of delay circuit unclamps starting switch K, under the situation that starting switch K disconnects, circuit still is in conducting state.At this moment, if main output plughole is non-loaded or load is less, the magnitude of voltage that sample circuit takes out is not enough to drive relay J 2 work after amplifying, then relay switch JK2 disconnects, secondary output plughole CZ2 does not have electricity, and delay circuit moves after through the delay time of setting, and makes relay J 1 dead electricity, relay switch JK1 disconnects, thereby cuts off the general supply of socket.If main output plughole CZ1 load is bigger, then the voltage of sample circuit taking-up is through amplifying 2 adhesives of rear drive relay J, make the closed conducting of relay switch JK2, secondary output plughole CZ2 gets, simultaneously by feedback circuit to the delay circuit feedback information, then delay circuit stops time-delay, and major and minor output plughole CZ1, CZ2 continue energising work.
Delay circuit in the utility model is that capacitor C 3, C5 and triode Q1 connect to form by time delay module NE555 and peripheral resistance R 5, R6.The direct current of DC power supply circuit output is time delay module NE555 more satisfactory direct-current working volts is provided after resistance step-down, electric capacity rectification.
DC power supply circuit described in the utility model is resistance R 1-R4, capacitor C 1, C2, and voltage-stabiliser tube DW1, DW2 and diode D1 connect and compose.Like this, the 220V AC power obtains the direct current of low pressure behind resistance step-down, electric capacity rectification, voltage-stabiliser tube voltage stabilizing, capacitor filtering.This DC power supply circuit is simple, reliable, durable.
Feedback circuit described in the utility model is the resistance-capacitance network that is connected to form by resistance R 14 and diode D4, D5.The feedback circuit stable performance of this structure, volume is less.
The utility model is set up delay circuit and feedback circuit in the circuit of master-slave mode electric outlet, make it when having can be with the startup of the main equipment driven characteristics of slave unit, delay circuit also can be according to the situation of enabling of the main equipment of the feedback of feedback circuit, delay cut-off or stop the continued power of delaying time, can realize closing automatically of general supply without manual operation, solve the problem of electrical appliance standby power consumptions such as TV, computer, increased the safety in utilization and the useful life of electrical equipment.Because of delay circuit has time delay, after electrical equipment shuts down because of misoperation, need not restart power supply, can in the time of time-delay, realize restarting of electrical equipment, it is convenient more to use.
