Embodiment
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is described in further detail, but not the restriction to described technology contents.
As shown in Figure 1, its inside of Lightning charging data line of display charged state of the present invention includes current detection module (being made up of GND wire and comparator), microprocessor, LED light, wherein: GND wire is used for doing current sense resistor, resistance is about 40 ~ 60 milliohms, when there being charging current to flow through GND wire, a magnitude of voltage can being produced and be transported on comparator.The mains switch opening microprocessor can be controlled after comparator detects charging current, and the signal charged or be full of is flowed to microprocessor.The signal that microprocessor detects charging or is full of, lights correct indicator light, bright orange lamp during charging, BG colored lights when being full of.Operation principle as shown in Figure 2.
All current detection circuits all need to connect a current sense resistor on charge circuit, and series current detects the impedance that resistance all can increase charge circuit.MFI certification for the requirement of Lightning charge circuit impedance is: the impedance in DC charging loop can not more than 200 milliohms.In order to address this problem, the ground wire of charging data line is used as the resistance of current detecting by this product, length due to this charging data line is 1m, we select the resistance of the long gnd conductor of this 1m to be about 40 ~ 60 milliohms, enough be used as current sense resistor, and the resistance of the 1m cathode power supply line selected is 120 ~ 140 milliohms, total resistance is added up can not more than 200 milliohms.
MFI for the quiescent current of Lightning data wire autophage is: only connect USB end, does not connect Lightning end, and this product consumes under the voltage of 5V has quiescent current can not more than 1mA.The circuit such as current detection module, microprocessor, LED all need current sinking, and total current during these circuit workings is inherently more than 1mA.In order to address this problem, the method that this product adopts is, when not connecting Lightning end, this product is in idle state, thus microprocessor and LED are all turned off power supply and do not allow its work to reduce quiescent current, there is connection once Lightning end, power immediately to microprocessor by its work.
Most current detection module is all adopt the analog-to-digital mode of AD, this product be then innovatively have employed a small size, high accuracy, low-power consumption comparator be used as current detection module, simultaneously also using the power supply switch controller of this comparator as microprocessor, only being connected to Lightning rectifies when charging, just open current switch, microprocessor work, lights correct indicator light.
Fig. 3 is the outside general structure of the Lightning charging data line of the display charged state described in the present patent application, comprise usb 1, Lighting interface 2 and be connected the connecting line 3 of said two devices, MFI for the requirement of Lightning overall dimensions is: thickness can not more than 6.25mm, width can not more than 12mm, and length can not more than 20mm.In order to solve overall dimensions problem, current detecting and corresponding control circuit are placed on the pcb board of USB side by this product, and LED is placed on Lightning plug side and USB side, by increasing the LED of internal core quantity control Lightning side.
Fig. 4 and Fig. 5 is the illustraton of model of Lightning end, and aluminum alloy casing 20 is provided with transparent internal mold 21, MFI in it and for the requirement of Lightning moulded dimension is: thickness can not more than 6.25mm, and width can not more than 12mm, and length can not more than 20mm.The welding figure that Fig. 6-7 holds for Lightning, two-sidedly in PCB 22 to be equipped with in indicator light 23(embodiment as dual-colored LED indicator light), USB core 24, indicator light control line 26 and current detecting line 27 be welded on each self-corresponding position respectively, the end of interface is provided with copper button 25, for pushing down wire rod web.Adopt illustrated welding manner, both can reduce the length of Lightning model, the decortication point of wire rod also can be made as far as possible near Lightning plug, entering so just to see viewed from transparent SR can not core, makes model more attractive in appearance like this.Meanwhile, have a LED at the diagonal angle of the front and back of pcb board, make SR printing opacity evenly.
The Lightning charging data line of the shown charged state described in the present patent application, unusual from style, more by the liking of consumer, add in the circuit of this product to add and manyly to design cleverly, it is made smoothly by the certification of MFI, consumer to be used more relieved.
