Description

A kind of charger with charge protection function
Technical field
The utility model relates to appliance field, particularly a kind of charger with charge protection function.
Background technology
Modern society is a society with fast rhythm, is a headachy thing such as the battery charge of various portable electric appts such as mobile phone, personal electric assistant (PAD), MP3.Except using the different chargers because of different electronic products, also need seek suitable socket during charging, use very inconvenient, though occur the charge power supplies of using on the market more, can not be reasonably charge according to the electric weight of equipment needs, and, can't be for equipment provide stable voltage, voltage is fluctuated can to stimulate battery, influences the life-span of battery, in addition, use charger that can not safety is placed charging device electric leakage problem, therefore, there is defective in prior art, needs to improve.
The utility model content
The technical problems to be solved in the utility model is for overcoming weak point of the prior art, provide a kind of simple structure, volume small and exquisite, be convenient to deposit, carry, easy to use, take into account the charger with charge protection function of fail safe simultaneously.
For solving technical problem of the present utility model, the technical scheme that adopts is: a kind of charger with charge protection function, comprise the power connector end mouth, input part, efferent, it is characterized in that: described input part is connected with described power connector end mouth, described power connector end mouth connects external power supply, be used to described input part that input voltage is provided, described efferent comprises the power rectifier module, output port, described power rectifier module is connected with output port, described efferent arranges voltage stabilizing circuit, protective circuit, described power rectifier module is connected with voltage stabilizing circuit, and described voltage stabilizing circuit is connected with output port by described protective circuit;
Described input part comprises change-over circuit, high frequency conversion circuit, and described change-over circuit is connected with described high frequency conversion circuit, and described high frequency conversion circuit is connected with efferent;
Described output port is USB port.
Beneficial effect with respect to prior art is at charging circuit protective circuit to be set, protection charging road road safety; reduce potential safety hazard, connected voltage stabilizing circuit, for power consumption equipment provides burning voltage; minimizing prolongs its useful life to the stimulation of the battery of power consumption equipment.
Description of drawings
Fig. 1 is framework map of the present utility model.
Embodiment
Below in conjunction with accompanying drawing optimal way of the present utility model is described in further detail.
As shown in Figure 1, this have charger simple structure, the volume of charge protection function small and exquisite, be convenient to deposit, carry, easy to use, take into account fail safe simultaneously.This has the charger of charge protection function, comprise power connector end mouth 1, input part 7, efferent 4, described input part 7 is connected with described power connector end mouth 1, described power connector end mouth 1 connects external power supply, be used to described input part that input voltage is provided, described efferent 4 comprises power rectifier module 9, output port 5, described power rectifier module 9 is connected with output port 5, described efferent 4 arranges voltage stabilizing circuit 8, protective circuit 6, described power rectifier module 9 is connected with voltage stabilizing circuit 8, and described voltage stabilizing circuit 8 is connected with output port 5 by described protective circuit 6;
Described input part comprises change-over circuit 2, high frequency conversion circuit 3, and described change-over circuit 2 is connected with described high frequency conversion circuit 3, and described high frequency conversion circuit is connected with efferent;
Described output port is USB port.
When circuit was connected, the input voltage that change-over circuit is used for the power connector end mouth was converted to the voltage that is fit to the high frequency conversion circuit, and change-over circuit is connected with the high frequency conversion circuit; This high frequency conversion circuit is converted to the direct voltage of change-over circuit output the alternating voltage of high frequency; this high frequency conversion circuit adopts full-bridge or half-bridge topology circuit; this high frequency conversion circuit is connected with the power rectifier module; behind the alternate voltage rectification of power rectifier module to the high frequency of high frequency conversion circuit output; provide stable voltage by voltage stabilizing circuit for output port; and import the electronic product of connection again by protective circuit; easy to use; minimizing is to the stimulation of the battery of power consumption equipment; prolong its useful life, the safe handling of protection power consumption equipment charging process.
The above execution mode only is used for illustrating the utility model, but is not limited thereto.Under the condition that does not depart from the utility model design, affiliated technical field personnel can make suitable change adjustment, and these change adjustment also should be included within the claim protection range of the present utility model.
