Abstract
The invention discloses an emergency power supply for a mobile phone. The emergency power supply for the mobile phone comprises a battery box, wherein an output lead is connected to an anode and a cathode of the battery box; and the other end of the lead is connected with a charging plug adaptive to a charging socket of the mobile phone. The emergency power supply for the mobile phone, disclosed by the invention, can be used for charging the mobile phone in emergency instead of a mobile phone charger and can be used for providing emergency power supply to the mobile phone under the circumstance that an alternating current power supply cannot be obtained.
Description
Technical field
The present invention 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 invention provides a kind of mobile phone stand-by power supply.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 used in the present invention is: 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.
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.
Operation principle of the present invention is: during use, to put into dry cell as external direct current power supply in the battery case of the present invention, 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 invention is: alternative charger for mobile phone is the mobile phone emergent charging.Power supply especially is provided for mobile phone is emergent under the situation that can't obtain AC power.
Description of drawings
Fig. 1 is a schematic perspective view of the present invention.
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. a mobile phone stand-by power supply 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. mobile phone stand-by power supply as claimed in claim 1 is characterized in that, is in series with diode on an output lead therein.
