Abstract
The utility model discloses a vehicular iphone charging device, which comprises a PCB (Printed Circuit Board) as well as a USB (Universal Serial Bus) interface and a miniUSB interface that are welded in the PCB, wherein a current detection resistor for voltage dividing is arranged on the PCB, and the current detection resistor is electrically connected to the USB interface and the miniUSB interface. The vehicular Iphone charging device disclosed by the utility model has the beneficial effects of being capable of conveniently charging apple products, such as iphone on a vehicle and providing convenience for users of the apple products.
Description
Technical field
The utility model relates to a kind of vehicle-mounted charging device, specifically a kind of iphone vehicle-mounted charging device.
Background technology
Traditional vehicle carried mobile phone charging device is to realize by 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
For the problem that above-mentioned prior art exists, the utility model provides a kind of iphone vehicle-mounted charging device, by this charging device, can charge for iphone in car.
To achieve these goals, the technical solution adopted in the utility model is: a kind of iphone vehicle-mounted charging device, comprise pcb board and be welded on USB interface and miniUSB interface on the pcb board, be provided with the inspection leakage resistance for dividing potential drop on the pcb board, this inspection leakage resistance is electrically connected on USB interface and miniUSB interface.
Preferably, described 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 the resistance of two-way series connection was in parallel after R3 connected with R4.
The beneficial effects of the utility model are: by 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.
