Description
Technical field
The utility model belongs to battery of mobile phone protective device technical field, is specifically related to a kind of over-charge protective smart jack.
Background technology
At present, some smart jacks have appearred in market, and they are divided into Metering socket, regular socket and remote control socket, and these smart jacks still can consume electric energy when not using, create unnecessary energy waste, therefore there is certain use limitation.
Summary of the invention
The utility model is overcome the deficiencies in the prior art to provide a kind of structure over-charge protective smart jack simple and easy to use.
The technical solution of the utility model is: a kind of over-charge protective smart jack; it is characterized in that the plug that comprises housing and be arranged at enclosure interior and control chip; wherein control chip comprises current sensor, switching circuit and control circuit; described current sensor is connected with control circuit with switching circuit, plug respectively by circuit, and switching circuit is connected with power supply with control circuit respectively by circuit.
The utility model is convenient for carrying, Based Intelligent Control, effectively prevent the generation that mobile phone overcharges phenomenon, not only reduces unnecessary energy waste, and alleviate the damage to battery of mobile phone, extend the useful life of battery of mobile phone.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model, and Fig. 2 is the wire connecting block figure in the utility model use procedure.
Drawing illustrates: 1, housing, 2, plug, 3, control chip.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
A kind of over-charge protective smart jack; comprise housing 1 and be arranged at plug 2 and the control chip 3 of housing 1 inside; wherein control chip 3 comprises current sensor, switching circuit and control circuit; described current sensor is connected with control circuit with switching circuit, plug 2 respectively by circuit, and switching circuit is connected with power supply with control circuit respectively by circuit.
Control principle of the present utility model is:
1, the solution of overcharged problem
Battery of mobile phone is when unsaturation state, control chip is in channel status, electric current charges by smart jack, after reaching the current amplitude of trickle charge, will being detected by current sensor, by judging to send instructions to control unit, then by control unit, switching circuit passed in corresponding instruction, and then realize becoming off state from channel status by switching circuit, now mobile phone will not recharge;
2, charging limit in limit uses the solution of charging problems
When mobile phone charges on use limit, limit, most cases charged electrical flow is greater than practical current sinking amount, but mobile phone trickle charge stream now will be greater than trickle current when not using at ordinary times, now smart jack is judged as that mobile phone now works, power down process can not be given, when not re-using, the trickle current reached at ordinary times is, in smart jack, control chip receives instruction, off state is converted to by channel status, after use consumes certain electricity, battery is no longer in saturation condition, now send instruction, in smart jack, control chip receives instruction, be converted to channel status by off state and continue charging,
The solution of 3, energy waste problem
After battery of mobile phone is in saturation condition, smart jack, by control chip auto-breaking, avoids unnecessary energy waste problem;
4, the solution of battery loss problem
After battery of mobile phone is in saturation condition, continues charging, battery can be made to be in hypersaturated state, handset battery life can be made like this to shorten, use smart jack can prevent the damage to battery of mobile phone.
Above embodiment is only and technological thought of the present utility model is described; protection range of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technical scheme basis is done, all falls within the utility model protection range.
