Abstract
The utility model discloses a mobile phone emergency charger, which comprises a battery box. The anode and the cathode of the battery box are connected with an output wire. The other end of the wire is connected with a charging plug which is adaptive with the charging jack of the mobile phone. The utility model can replace the mobile charger to charge the mobile phone in emergency, particularly when an AC power supply is not available.
Description
Technical field
The utility model relates to a kind of charger for mobile phone, especially emergent charger for cell phone.
Background technology
At present, mobile phone inside all carries charging management chip, promptly (mostly is 5～9V) and can both regulates the voltage and current that charges normal that output meets battery of mobile phone automatically behind external direct current power supply.Present charger for mobile phone is the Switching Power Supply that the 220V alternating current is transformed to direct current 5V (minority is 6V or 9V) normal voltage.The dc voltage stability of its output is reliable, and available maximum operating currenbt mostly is about 500MA.When people in no AC-powered (as the field) and during the battery of mobile phone short of electricity, influence is normally used.
Summary of the invention
In order to overcome the technical problem that existing mobile phone can not charge under no Alternating Current Power Supply occasion, the utility model provides a kind of emergent charger for cell phone.This charger can be carried, and is the mobile phone emergent charging timely under no alternating current situation, makes things convenient for the cellphone subscriber normally to use mobile phone.
The technical solution adopted in the utility model is: a kind of emergent charger for cell phone, and it comprises a battery case, is connected with output lead on the both positive and negative polarity of battery case, the other end of lead is connected with the charging plug adaptive with the cell-phone charging socket.
For electric current can only be flowed out from the powered battery end, prevent the mobile phone that unexpected wiring error causes and the damage of charger, be in series with diode on an output lead therein.
The utility model operation principle is: during use, to put into dry cell as external direct current power supply in the utility model battery case, generally put into 4 joint 1.5V batteries and can reach the voltage value suitable with charger for mobile phone, after the charging management chip that utilizes mobile phone inside to carry is regulated automatically, for battery of mobile phone provides suitable charging voltage and electric current.
Good effect of the present utility model is: alternative charger for mobile phone is the mobile phone emergent charging.Especially emergent for mobile phone under the situation that can't obtain AC power.
Description of drawings
Fig. 1 is a schematic perspective view of the present utility model.
Among the figure: 1--battery case, 2--diode, 3--USB socket; The 4--plug.
Embodiment
As shown in Figure 1, it comprises the battery case 1 that can adorn four joint 1.5V dry cells, four batteries series connection back output supply power voltage in the battery case 1.Powering is connected with output lead on the positive and negative plate, and the other end of output lead is connected with the charging plug 4 adaptive with the cell-phone charging socket.A diode 2 is installed in the battery case 1, and diode 2 forward is connected on wherein output lead of battery case 1.A USB socket 3 also can be installed on the box body, flexibly connect by USB socket 3 and output lead (cell-phone charging line).The purpose of using USB socket 3 be for market on the cell-phone charging line of a large amount of band USB plug be complementary.
During use, the dry cell of packing into connects mobile phone by the cell-phone charging line of being with USB plug and promptly can be cell-phone charging.
Claims (2)
1. an emergent charger for cell phone is characterized in that, it comprises a battery case, is connected with output lead on the both positive and negative polarity of battery case, and the other end of lead is connected with the charging plug adaptive with the cell-phone charging socket.
2. emergent charger for cell phone as claimed in claim 1 is characterized in that, is in series with diode on an output lead therein.
