Abstract
The utility model discloses a charger, in particular to a charger for charging a plurality of mobile phones simultaneously, which comprises a housing, a plug and a USB output port arranged fixedly on the housing, and a charge circuitry board in the housing, wherein two or more USB output ports arranged fixedly on the housing are provided. The utility model is provided with two or more USB output ports and battery charge modules with corresponding numbers as the USB output ports, so that one charger can charge plural mobile phones simultaneously, thereby solving the problem that one mobile phone is only matched with one charger. The utility model is suitable for family, office, and power station.
Description
Technical field
The utility model relates to a kind of charger, especially relates to a kind of multi-section mobile phone and charges simultaneously and use charger.
Background technology
Raising along with people's level of consumption, the cellphone subscriber increases rapidly, only domestic cellphone subscriber just has more than one hundred million people, and every mobile phone all is furnished with a charger, and the different brands charger for mobile phone is not general mutually, and mobile phone updates soon in addition, and much the charger that can also use can only be taken as garbage disposal, this has not only increased consumer's burden, also increased energy and material consumption, at present, though mobile phone industry has been unified the charger national standard, but the charger of new production also can only be joined a mobile phone by a charger, yet present general family has the mobile phone more than two ones, needs to buy a plurality of chargers, this is very inconvenient, has also increased the consumption burden.
The utility model content
The utility model technical issues that need to address provide a kind of charger that can charge simultaneously for multi-section different brands mobile phone simultaneously.
For achieving the above object, technical solution adopted in the utility model is: a kind of multi-section mobile phone charges simultaneously and uses charger, comprises housing, is fixed in plug, usb delivery outlet on the housing, be positioned at the charging circuit plate of housing, the usb delivery outlet that is fixed on the housing is two or more.
Further improvement of the utility model is: the charging circuit plate is formed by power converter module with the corresponding battery charging module of usb output port number
Adopt the beneficial effect that technique scheme produced to be: charger have two or more usb delivery outlets and with the corresponding battery charging module of usb output port number, making a charger can be the multi-section mobile phone charges simultaneously, solved a mobile phone and joined the problem of a charger, be applicable to family, office, add the power station and use.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is this utility power converter module circuit diagram,
Fig. 3 is this practical battery charging module circuit diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
As shown in Figure 1, the utility model charger is made up of housing 2, Charger (portable round) 1, wiring board 3, usb delivery outlet 4, Charger (portable round) 1 is fixed on the housing 2, be fixed with 4 usb delivery outlets 4 on the housing 2, wiring board 3 is loaded in the housing, charging circuit on the wiring board is made of power converter module and 4 tunnel battery charging module, the corresponding usb delivery outlet 4 of every road battery charging module, every road charging module has the charging of adopting luminous tube and is full of indicator light, have 8 indicator lamp holes on the corresponding housing 2, the luminous tube head is exposed outside the housing 2 slightly.
As shown in Figure 2, power converter module is to be the Switching Power Supply of core with isolated pulse-width modulation single-chip switching power supply chip IC 1, capacitor C 1, magnetic core inductance L 1 constitutes elementary filter circuit, the high order harmonic component that the filtering Switching Power Supply produces, rectifier bridge BR1 carries out rectification for 220 volts with the alternating current of input, by capacitor C 2 filtering, voltage-stabiliser tube D1, diode D2 is used to clamp down on the forward position due to voltage spikes that is produced by transformer T1 leakage inductance, the voltage that transformer T1 secondary coil produces is through diode D3, capacitor C 4, C6,6.5 volts of the direct voltages of output smoothing behind inductance L 2 rectifying and wave-filterings, the voltage of output is through resistance R 1, R2, voltage-stabiliser tube D5, optocoupler IC takes a sample, after output voltage changes, electric current by optocoupler luminous tube part changes, the electric current of optocoupler receiving unit changes, the pulse duty factor of control single-chip switching power supply chip IC 1, make output voltage stabilization, simultaneously, resistance R 2, voltage-stabiliser tube D5 provides a preload, the load regulation when improving underloading for output voltage.The biasing winding provides voltage through diode D4, capacitor C 5 rectifying and wave-filterings generation bias voltage for the control pin of single-chip switching power supply chip IC 1, capacitor C 3 is for restarting control capacitance automatically, the control utmost point drive current spike of the single-chip switching power supply of filtering simultaneously chip IC 1, capacitor C 7, C8 are used for the common mode emission current that electric capacity produces between filtering transformer T1 primary and secondary coil.
As shown in Figure 3, battery charging module is to be the battery charger of core with battery charging management chip U1, anti-interference capacitor C1 is connected to 8 pin and 15 pin of chip U1, resistance R 3, R4, three machine pipe Q1, diode D1 forms the battery charge drive circuit, potentiometer W1, resistance R 1 is used to be provided with the breakover voltage that constant-current charging of battery changes constant voltage charge, the breakover voltage of this machine setting is 4.2 volts, resistance R F is used to control the constant current charge electric current of charger, the charging current of this machine setting is 320 milliamperes, resistance R 5, R6, luminous tube D2, D3, capacitor C 2 is formed the charging display circuit, when battery charge, the 6 pin output high level of chip U1, D2 is luminous for the driven for emitting lights pipe, and indication is charged, luminous tube red LED luminous tube, when battery is full of, the 6 pin output low levels of chip U1, D3 is luminous for the driven for emitting lights pipe, pilot cell is full of, luminous tube green LED luminous tube.
Adopt the charger of such scheme, solve a mobile phone and joined the problem of charger, reduced resource consumption, alleviated consumer's burden, this charger also is suitable for directly battery being charged, and does not pass through mobile phone, there is the user of polylith battery especially suitable for a mobile phone, this charger is used for family, office, add place such as power station, and is very practical, can also play energy-saving and cost-reducing effect.
