Embodiment 1

[0015] Embodiment 1: As shown in the figure, a portable mobile phone charger includes a dry battery 1 for providing charging current, a charging main circuit 2, a plug socket 3 and a charging indication circuit 5, and the plug socket 3 is provided with mutually non-conductive The first output terminal 31, the second output terminal 32 and the third output terminal 33, the plug-in switch 4 is arranged between the second output terminal 32 and the third output terminal 33, the first output terminal 31, the second output terminal 32 and The third output terminal 33 is respectively connected with a first output jack (not shown), a second output jack (not shown) and a third output jack (not shown), the plug-in switch 4 is a conversion plug, One end of the conversion plug is provided with a mobile phone charging plug 44, and the other end of the conversion plug is provided with a conversion plug (not shown), and the conversion plug is provided with a first output terminal 31, a secon...

Embodiment 2

[0017] Embodiment 2: Other structures are the same as Embodiment 1, the difference is that the third output terminal 33 is connected to the shell of the plug socket 3, the third input terminal 43 is connected to the shell of the conversion plug, and the shell of the plug socket is connected to the shell of the conversion plug. The housings of the plugs match each other.

Abstract

The invention discloses a portable mobile phone charger, which comprises a dry battery for providing charging current, a charging main circuit and a plug socket, the positive pole of the dry battery is connected to the input end of the charging main circuit, and the plug socket is provided with a first non-conductive An output terminal, a second output terminal and a third output terminal, the output terminal of the charging main circuit is connected to the first output terminal through the third resistor for current limiting, the ground terminal of the charging main circuit is connected to the second output terminal, the dry battery The negative pole of the dry battery is connected to the third output terminal, and a plug-in switch is arranged between the second output terminal and the third output terminal. Conduction, and when the plug-in switch is pulled out, the negative pole of the dry battery and the ground terminal of the charging main circuit are not conductive to each other, so no static operating current is generated.

Description

technical field [0001] The invention relates to a mobile phone charger, in particular to a portable mobile phone charger. Background technique [0002] Most of the existing mobile phone chargers are AC mobile phone chargers, which are bulky and heavy, not very convenient to carry, and must be charged with 220V alternating current. Sometimes people work in the field, travel or on long-distance vehicles, and encounter the situation that the mobile phone is out of power, and these places often have no AC power supply. This embarrassing situation is very troublesome. The application number is 200410027048.8 Chinese Invention Patent Application Publication, which discloses a dry battery type mobile phone charger, including: a cavity for a built-in dry battery as a power source, used for connecting the output electrodes of the battery, protruding from the outside of the appliance for use The plug connected to the charging interface of the mobile phone is a circuit that connects t...
