Abstract
The utility model belongs to a pager (BP set) battery charger which can be used for charge a secondary battery or a common battery, particularly charge for a battery (such as 5#-7#) in a BP set. The utility model is composed of resistors, diodes and light-emitting diodes. The pager (BP set) battery charger is characterized in that both ends of a charged secondary battery are connected with a diode D< 3 > in parallel. One end of the pager (BP set) battery charger is connected with the end B of a power input by a diode D< 2 > and R< 2 >, R< 1 >. The other end is connected with the end An of the power input. The utility model has the characteristics of less elements, simple circuit, high reliability and favorable charge performance. The pager (BP set) battery charger can effectively improve the utilization rate of the batteries.
Description
The utility model belongs to a kind of battery charger.
Along with the development of beeper, increased a lot of convenience for people's life, and the user need often to change battery, has brought many troubles really.
Existing in the market charger because the circuit complexity, thereby repairs very inconveniently, and in addition, owing to cost an arm and a leg, ordinary consumer is not dared to inquire.This practical goal of the invention just provides a kind of can the charging for rechargeable battery, also can be the charger of common batteries charging, it has characteristics such as element is few, circuit is simple, charging performance is good, and global reliability height, low price, energy savings, reduce expenses, can improve the utilance of battery.
Charger described in the utility model is whole circuit charging, series electrical streaming.Have charge indicator in the charger, be used for the operating state of monitoring battery charging, this charger only needs 220 volts of AC power and gets final product work.
After energized, when battery was in charging, light-emitting diode was shinny, makes indication, to show this charger operate as normal.When cutting off the electricity supply or during the power supply loose contact, charger quits work, indicating device is not given instruction.Be recharged battery and install when incorrect, charger is not worked yet.
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing 1 is circuit theory diagrams of the present utility model.
As shown in FIG.: be parallel with diode D at the two ends that are recharged battery
3, an end that is recharged battery is respectively by diode D2, resistance R
2, resistance R
1Be connected with the B end of power supply input, the other end that is recharged battery is connected light-emitting diode D with the A end of power supply input
1With resistance R
3Be connected in parallel on resistance R after the series connection
1On.After A, B add 220 volts of alternating voltages, when alternating current is positive half cycle, can pass through R at 2
1, R
2, D
2After current limliting, the rectification, be the direct current of 7-9mA, to 1.5 volts of battery charge.
When alternating current is transformed to negative half period, because of D
2The principle of the unidirectional conducting of diode, so electric current is cut off, moment stops charging.When the circuit operate as normal, there is electric current to exist in the circuit, so, at R
1Two ends form voltage, around this principle, after the light-emitting diode series connection proper resistor, can be luminous.It is that provable charger is in charged state at this moment that this indication is arranged.
D
3In the time of can being used for eliminating negative half period, D
2Leakage current, thereby staticize and improve quality of cummutation.
Claims (2)
1, a kind of beeper battery charger is made up of resistance, diode, light-emitting diode, it is characterized in that: be parallel with diode D at the two ends that are recharged battery
