Abstract
The utility model discloses a power source multi plug socket with automatic switch which comprises a power source multi plug socket, a load and a relay. A master load LP is connected with the power source and the output end of the master load LP is connected with the diode D6 before connected with the control end of the relay J whose one end is connected with the power source and the other end of the relay J is connected with a secondary load LS. The utility model is used in on line equipment. The power source of accessory equipment turns on and off according to the on and off of the master equipment. The utility model is convenient to use and can reduce energy waste. The utility model has the advantages of simple structure, low cost, excellent reliability and is particularly suitable for equipment that can have electricity power supply capacity including computer, etc.
Description
Technical field
The utility model relates to power distributor, mainly is meant a kind of power distributor with automatic switch.
Background technology
Now a lot of household electrical appliance all are online uses, need use power amplifier and television set simultaneously in the time of such as use DVD; To use display, audio amplifier and printer in the time of computed.These equipment are connected on the civil power by the electric socket of a normal open, and the problem of existence has two: 1, inconvenient in the use: all will open online equipment mutually in the time of each the use successively, close one by one after finishing using again; 2, waste energy: modern on the one hand electrical equipment majority all has idle function, and several watts power consumption is in fact still arranged under the holding state, and it is very considerable numeral that these wastes add up throughout the year; The user is for carelessness easy to use or that use on the other hand, do not close a certain on-line equipment, waste that even more serious (active audio amplifier producer is attractive in appearance for product for instance, usually power switch design in more hidden place, switch inconvenience, turn off be easy to forget behind the computer close audio amplifier).
Summary of the invention
The purpose of this utility model provides a kind of power distributor with automatic switch, relay promptly is set in socket, and this relay separates capital equipment and minor equipment, and minor equipment must be powered through relay, relay is controlled by circuit, plays the effect of switch.This power distributor has overcome the deficiency that the existing power supply socket exists.
The realization the technical solution of the utility model is: this power distributor comprises power distributor, load, relay, its major technique is that main load LP connects power supply, succeed electrical equipment J control end behind its output cross-over connection diode D6, relay J one termination power, its another termination time load LS.
Technique scheme also comprises: main load LP succeeds electrical equipment J control end behind USB interface cross-over connection diode D6.
The beneficial effect that the utlity model has: this socket is used for mutually online equipment, the power supply of minor equipment according to the unlatching of capital equipment with open or disconnect, convenient use reduces energy waste.The advantage of structure is simple in structure, with low cost, good reliability, is specially adapted to the equipment that computer etc. has external power supply capacity.
Description of drawings
Fig. 1 is the circuit block diagram of passive type structure in the utility model.
Fig. 2 is one of circuit theory diagrams of Fig. 1.
Fig. 3 be Fig. 1 circuit theory diagrams two.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Referring to accompanying drawing, Fig. 1 is the circuit block diagram of passive type structure in the utility model.Among the figure, Lp is main load, and J is a relay, and Ls is time load, and main load Lp is connected on two power lines, and power line is given main load Lp power supply, and main load Lp output is connected with the control end of relay J, and inferior load Ls is connected with power line by relay J.When opening, main load Lp powers to relay J by the cable that connects relay J, the relay J closure, and inferior load Ls obtains power supply; Main load Lp closes, and no longer to the relay J power supply, relay J disconnects, inferior load Ls outage.
Referring to Fig. 2, between two control ends of relay J, be connected with diode D6, oppositely the diode D6 that connects is used to absorb the backflow voltage that produces when relay disconnects, and the protection front stage circuits then can not omitted if the relay that is adopted does not produce backflow voltage.
Most preferred embodiment
Referring to Fig. 3, the passive type structure that the USB cable by main load connects is that best product constitutes.Wherein Lp can be main frame or miscellaneous equipments such as DVD with USB interface; Ls can be display, audio amplifier, printer etc.; Cable connector is the USB input adapter, Data+ in the USB input adapter and Data-put sky need not, only Vcc and GND are connected respectively to the positive and negative electrode of relay J control end.
Basic load Lp and less important load Ls can have only one or more being connected in parallel.
Can also there be accomplished in many ways the circuit aspect, as:
Relay backflow absorption diode D6:, then can omit if the relay J that adopts can not produce backflow.
Above-mentioned all circuit close with present technique all belong to this patent protection range.
Claims (2)
1. the power distributor with automatic switch comprises power distributor, load, relay, it is characterized in that main load LP connects power supply, succeeds electrical equipment J control end behind its output cross-over connection diode D6, relay J one termination power, its another termination time load LS.
2. the power distributor with automatic switch as claimed in claim 1 is characterized in that main load LP succeeds electrical equipment J control end behind USB interface cross-over connection diode D6.
