The switch, the current detecting circuit and a plurality of unit sockets are arranged on the shell body of the multiple socket; each of the unit sockets is composed of a positive pole jack, a negative pole jack and an earth jack and is provided with an indicating lamp used for displaying the switching conditions of the power supply of each of the unit sockets; a power supply line at one end on the shell body is connected with the switch and is orderly connected with control circuits of all the unit sockets through overcurrent protectors for controlling each unit switch to orderly and respectively supply electricity or cut off the electricity supply according to the settled time interval.
Description
The power control of the relevant a kind of multi-gang socket of the utility model, refer in particular to a kind of power supply control of multi-gang socket, can control or when manual switch connects ON or cuts out OFF by computer, each unit socket is at interval low power supply or the outage respectively successively of setting-up time, with prevent to power simultaneously or cut off the power supply the interference that generates electromagnetic waves and moment circuit overload cause danger.
The power supply of the employed traditional multi-gang sockets of power supply such as audio-visual group of PC group and television acoustics control in the past has following two kinds: the first is only established a master switch, in use when master switch connects ON or cuts out OFF, the electrical equipment that is plugged on each unit switch is powered simultaneously or is cut off the power supply, cause line current moment to carry excessive and cause danger easily, and the interference that is easy to generate electromagnetic waves.Another kind is except that being provided with master switch, and each unit socket also respectively has switch-dividing.When master switch was connected, essential each switch-dividing was all in off-position.Not so, the identical defective of aforementioned one is promptly arranged.Therefore, when master switch is connected ON in use, must again each switch-dividing be operated to respectively one by one and connect the ON position.Need again during shutdown earlier each switch-dividing to be operated to the OFF position one by one respectively, not only inconvenience, and also time-consuming.
Main purpose of the present utility model is to solve aforesaid difficulty and power control that a kind of multi-gang socket is provided.
Main purpose of the present utility model is achieved in that the housing of this multi-gang socket is provided with switch, current detection circuit and a plurality of unit socket, each unit socket all is made of positive and negative electrode jack and earth jack, and is respectively equipped with one in order to show the indicator light of each unit socket power turn-on situation; It is characterized in that: it is a plurality of timing circuit institute be combined into by housing, switch and the current detection circuit that is linked in sequence, IC governor circuit, shaping circuit and engagement unit socket quantity; End power line on the housing connects switch, and through current detection circuit to the IC governor circuit, sequentially be connected behind the shaping circuit via the inverter formation again with control circuit each unit socket, that form by timing circuit and charging capacitor, in order to control each unit switch according to setting blanking time, power supply or outage respectively successively.
Each unit socket can be linear array on housing, also can be double arrangement.
Mains switch is by manual operation, also can connect the computer control switch.
The utlity model has following characteristics: 1, power supply of the present utility model control, can control or by the switch manual control by computer.When 2, master switch was connected, each unit socket is setting-up time at interval, one by one power supply respectively automatically after blanking time successively.3. when master switch cut out, each unit socket is setting-up time, outage respectively automatically after blanking time successively one by one at interval also.
Other purposes of the present utility model, structure and function with reference to embodiment and accompanying drawing, are described in detail as follows:
Fig. 1 is the outward appearance oblique view of the multi-gang socket of the utility model embodiment.
Fig. 2 is the block diagram of power supply control among Fig. 1.
Fig. 3 is the employed control circuit schematic diagram of the utility model embodiment.
At first see also shown in Figure 1ly, on the housing (2) of multi-gang socket of the present utility model (1) a plurality of unit sockets (3) are arranged, each unit socket (3) respectively has an indicator light (4), in order to show the situation of each unit socket (3) power turn-on.Each unit socket (3) can be linear array on housing (2), also can be double arrangement.On the housing of present embodiment (2); one end power line (5) connects switch (6) through live stream protector (7); be connected with the control circuit (8) (as Fig. 2, shown in Figure 3) of double six unit sockets (3); in order to control each unit switch (3) according to setting blanking time, power supply or outage respectively successively.Each unit socket (3) all is made of positive and negative electrode jack and earth jack, and has an indicator light (4) to show the situation whether it powers.
Fig. 2 and Figure 3 shows that control circuit (8) block diagram of each unit socket of the utility model (3) and the circuit diagram of use, when switch (6) is connected, electric current through current detection circuit (overload current protector (7)) to IC governor circuit (9), then C
