Fig. 3 is the structural representation of first pin among Fig. 2, second pin and load prongs.
[embodiment]
Please consult Fig. 2, Fig. 3 jointly, Fig. 2 is the electrical block diagram of automatic economize on electricity battery one preferred embodiment application state of the present invention, and Fig. 3 is the structural representation of first pin among Fig. 2, second pin and load prongs.
Automatic economize on electricity battery provided by the invention is connected with the load with load prongs 101 100, and in present embodiment, said automatic economize on electricity battery 20 comprises:
Earth resistance 23, one ends are connected other end ground connection with said first pin 21;
Connect resistance 25, one ends and be connected another termination power 24 with said second pin 22;
Switching circuit 26, its control end is connected with said second pin 22, and said control end obtains low level, then said switching circuit 26 closures, otherwise said switching circuit 26 breaks off;
Internal circuit 28 is connected with said switching circuit 26.
Wherein, said battery core pack 27 is two, said first pin 21, second pin 22, earth resistance 23, connects resistance 25 and all corresponds to two.Certainly, said battery core pack 27 also can be one, said first pin 21, second pin 22, earth resistance 23, connects resistance 25 and all corresponds to one.Said battery core pack 27 also can be for more than two, said first pin 21, second pin 22, earth resistance 23, connect resistance 25 and are all and said battery core pack 27 same number.
Wherein, said switching circuit 26 comprises metal-oxide-semiconductor; The grid of said metal-oxide-semiconductor obtains said low level, said metal-oxide-semiconductor conducting, said switching circuit 26 closures; Otherwise said switching circuit 26 breaks off.Certainly, said switching circuit 26 can also adopt other circuit structures, as long as guarantee when obtaining low level, and said switching circuit 26 closures; Otherwise said switching circuit 26 breaks off and getting final product.
Wherein, the power supply 24 that connected of said earth resistance 25 can be battery 20 internal electric sources; The internal electric source of said battery 20 can be the 3V power supply.
Wherein, said earth resistance 23 can be 390 ohm; The said resistance 25 that connects can be 100,000 ohm.Thereby after guaranteeing that said first pin 21, second pin 22 connect through said load prongs 101, said second pin 22 by drop-down be low level.
Please consult Fig. 3 again; As shown in the figure; Said load prongs 101 can be inserted 21 of said second pin 22 and said first pins, is connected with said first pin 21 thereby reach said load prongs 101, reaches said second pin 22 simultaneously and electrically connects with said first pin 21.
Under the situation that does not connect load 100, said switching circuit 26 obtains the high level that said second pin 22 produces, and said switching circuit 26 breaks off, thereby said battery core pack 27 is not connected with said internal circuit 26; Under the situation that connects load 100; Said first pin 21 is connected with said load prongs 101; Said battery core pack 27 gives load 100 power supplies, and said second pin 22 is connected through said load prongs 101 with said first pin 21, the signal on said second pin 22 by drop-down be low level; Said switching circuit 26 obtains the low level that said second pin 22 produces; Said switching circuit 26 closures, thus said battery core pack 27 is connected with said internal circuit 28, and said battery core pack 27 gives internal circuit 28 power supplies.
It is thus clear that under the situation that connects load 100, battery core pack 27 can be to load 100 power supplies; Do not connect under the situation of load 100, each battery core pack 27 to internal circuit 28 power supplies, does not reduce unnecessary power consumption.
