Abstract
The invention discloses a car charging device for iphone, comprising a PCB (printed circuit board), a USB (universal serial bus) interface and a mini USB interface which are welded on the PCB, wherein the PCB board is provided with a galvanometric resistor for dividing voltage which is electrically connected with the USB interface and the mini USB interface. The car charging device has the beneficial effects of conveniently charging the iphone and other apple products on the car and providing conveniences for the users of the apple products.
Description
Technical field
The present invention relates to a kind of vehicle-mounted charging device, specifically is a kind of iphone vehicle-mounted charging device.
Background technology
Traditional vehicle carried mobile phone charging device is to realize through cigar lighter or vehicle-mounted USB device output 5V voltage; Iphone is the mobile phone of a kind of innovation of Apple's release; Because its advantageous characteristic has been subjected to liking of more and more people, uses also increasingly extensive.When its charging principle and other mobile phone differences are to detect external equipment and possess charge condition just the activating charge system charge; Therefore; USB interface power supply on the general vehicle can not charge for iphone, and this has brought inconvenience for the user of iphone undoubtedly.
Summary of the invention
To the problem that above-mentioned prior art exists, the present invention provides a kind of iphone vehicle-mounted charging device, through this charging device, can in car, charge for iphone.
To achieve these goals; The technical scheme that the present invention adopts is: a kind of iphone vehicle-mounted charging device; Comprise pcb board and be welded on USB interface and the miniUSB interface on the pcb board; Pcb board is provided with the inspection leakage resistance that is used for dividing potential drop, and this inspection leakage resistance is electrically connected on USB interface and miniUSB interface.
Preferably, said inspection leakage resistance comprises 4 resistance, and it is respectively R1 that resistance is 75K and R3 and resistance is R2 and the R4 of 49.9K, and R1 connects with R2, and connect with the R4 resistance of back two-way series connection of R3 is in parallel.
The invention has the beneficial effects as follows: through the use of this charging device, can be easily on vehicle carry out charging operations for apple products such as iphone, for the user of apple products provides convenience.

Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
As shown in Figure 1: the present invention includes pcb board and be welded on USB interface and the miniUSB interface on the pcb board, pcb board is provided with the inspection leakage resistance that is used for dividing potential drop, and this inspection leakage resistance is electrically connected on USB interface and miniUSB interface.
Preferably, said inspection leakage resistance comprises 4 resistance, and it is respectively R1 that resistance is 75K and R3 and resistance is R2 and the R4 of 49.9K, and R1 connects with R2, and connect with the R4 resistance of back two-way series connection of R3 is in parallel.Series connection and parallel connection through 4 resistance obtain target resistance values.
Input miniUSB interface is inserted on the vehicle, and USB device on vehicle output 5V voltage is told 2V voltage through the inspection leakage resistance, the charging system on being used to Activate Phone, thus be reached for the purpose of apple products chargings such as iphone.
