Description
Technical field
The utility model relates to a kind of mobile phone, relates in particular to a kind of mobile phone of direct charging.
Background technology
Present cell-phone charging all needs to be connected mobile phone with special charger with external connection and charges, different mobile phones need be equipped with the external connection of different model, not only use trouble but also increased consumer cost, just more inconvenient the special user who handles affairs or travel for going out, the normal situation of leaving behind external connection and charger is gone out to bring inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of mobile phone of direct charging, needs the problem of external charge device when having solved cell-phone charging, and the charge circuit of mobile phone is connected the Charge Management loop of mobile phone inside, reaches the safe and reliable cell-phone charging of giving.
The utility model is achieved like this, it comprises mobile phone, the concealed plug of sliding push-pull, current rectifying and wave filtering circuit, switch voltage-stabilizing current-limiting circuit, isolation rectification output circuit, mobile phone charge inside management loop, it is characterized in that the mobile phone sidewall is connected with the concealed plug of sliding push-pull, the concealed plug of sliding push-pull connects current rectifying and wave filtering circuit, current rectifying and wave filtering circuit connects the switch voltage-stabilizing current-limiting circuit, the switch voltage-stabilizing current-limiting circuit connects the isolation rectification output circuit, and the isolation rectification output circuit connects mobile phone charge inside management loop.
The utility model has the advantages that: the automatic charging plug of mobile phone, be convenient to the mobile phone use of charging at any time, do not need to use the charger charging, easy to use, increased the surcharge of mobile phone.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a functional-block diagram of the present utility model.
Embodiment
As Fig. 1; shown in Figure 2; the utility model is achieved like this; mobile phone 1 sidewall is connected with the concealed plug 2 of sliding push-pull; the concealed plug 2 of sliding push-pull connects current rectifying and wave filtering circuit 3; current rectifying and wave filtering circuit 3 connects switch voltage-stabilizing current-limiting circuit 4; switch voltage-stabilizing current-limiting circuit 4 connects isolation rectification output circuit 5; isolation rectification output circuit 5 connects mobile phone charge inside management loop 6; charging plug adopts the concealed plug of sliding push-pull; so not only saved space but also attractive in appearance; the switching power supply circuit is adopted in this cell-phone charging loop; be provided with overvoltage (5.5 volts) protection and charging current (less than 450 milliamperes) restricting circuits in the loop; switch transformer uses the switch transformer of high-quality high frequency ferrite magnetic core, has high resistivity to reduce the heating that eddy current produces.It also is to realize by switch transformer that the electrical safety of high pressure (220v) and low pressure is isolated, and reaching safe and reliable charging, is that 30 maximum temperatures of charge circuit when spending are 45 degree at charging ambient temperature.This mobile phone uses 3.7 volts of 1630 milliamperes of lithium batteries, and 6.5 hours charging intervals can be full of, 420 milliamperes of maximum charging currents, and 5.2 volts of charging voltages, but the standby 10 days of once charging are play MP3 and are reached 8.5 hours under the operate as normal.
