Description
Technical field
The utility model belongs to technical field of data transmission, relates to a kind of miniSD interface adapter.
Background technology
Along with widely using of the movable memory equipments such as USB flash disk, SD card, increasing equipment is by providing the expansion of USB interface or SD Interface realization memory space.But, many portable sets only provide mini SD interface to realize Memory Extension usually, even if some equipment provides mini SD and USB interface simultaneously, but USB interface is not used to realize Memory Extension, but be defined by USB DEVICE to support this equipment of computer access, therefore, when not by other peripheral hardwares, portable set cannot realize the direct access to USB flash disk, standard SD card data, and this seems very inconvenient in daily life.
Utility model content
The purpose of this utility model is for prior art Problems existing, provides a kind of compact structure, miniSD interface adapter easy to use.
For this reason, the utility model adopts following technical scheme:
A kind of miniSD interface adapter, comprise housing, the side of described housing is provided with miniSD plug, and housing opposite side or both sides are provided with standard USB interface and standard SD card interface, housing is also provided with toggle switch, is provided with SD signal in housing to usb signal change-over circuit; Described toggle switch is two contact toggle switches, comprise two working ends and a stiff end, two working ends of described toggle switch are connected to usb signal change-over circuit and standard SD card interface with SD signal respectively by power line, the stiff end of toggle switch is connected with miniSD plug by power line, and between described standard USB interface with SD signal to usb signal change-over circuit, SD signal is connected between usb signal change-over circuit with miniSD plug, between standard SD card interface with miniSD plug by data wire.
Further, described standard SD card interface is also plugged with SD-miniSD adapter.
The beneficial effects of the utility model are: the utility model can enable the portable set with mini SD interface access USB flash disk and standard SD card simultaneously, makes portable set have more selection when extension storage; And the utility model compact structure, be convenient to daily going out and portably use.
Accompanying drawing explanation
Fig. 1 is structure principle chart of the present utility model;
Fig. 2 is the constructional appearance figure under visual angle, the utility model side;
Fig. 3 is constructional appearance figure under the utility model opposite side visual angle;
In figure, 1-housing, 2-miniSD plug, 3-standard USB interface, 4-standard SD card interface, 5-toggle switch, 6-SD signal to usb signal change-over circuit, 7-SD-miniSD adapter.
Embodiment
As Figure 1-3, a kind of miniSD interface adapter, comprise housing 1, the side of housing 1 is provided with miniSD plug 2, other three sides of housing 1 are respectively equipped with standard USB interface 3, standard SD card interface 4 and toggle switch 5, are provided with SD signal to usb signal change-over circuit 6 in housing 1; Toggle switch 5 is two contact toggle switches, comprise two working ends and a stiff end, two working ends of toggle switch 5 are connected to usb signal change-over circuit 6 and standard SD card interface 4 with SD signal respectively by power line, the stiff end of toggle switch 5 is connected with miniSD plug 2 by power line, and between standard USB interface 3 with SD signal to usb signal change-over circuit 6, SD signal is connected between usb signal change-over circuit 6 with miniSD plug 2, between standard SD card interface 4 with miniSD plug 2 by data wire; Standard SD card interface 4 is also plugged with SD-miniSD adapter 7.In the utility model, SD signal adopts special chip to usb signal change-over circuit 6, and its model can select AU6331, AU6367, CP2102 etc.
In Fig. 1, power line adopts fine line to represent, data wire adopts heavy line to represent, power line is used for providing power supply for associated components, and data wire is used for transmitting data information.In use procedure, when selecting USB flash disk as Memory Extension equipment, by USB flash disk connection standard USB interface 3, stir toggle switch 5, SD signal is communicated with to the power line between usb signal change-over circuit 6 with miniSD plug 2, SD signal obtains electric to usb signal change-over circuit 6, thus standard USB interface 3 and SD signal are connected to the data circuit between usb signal change-over circuit 6 and miniSD plug 2, and portable set can carry out data access to USB flash disk.When choice criteria SD card is as Memory Extension equipment, pull up SD-miniSD adapter 7, by standard SD card connection standard SD card interface 4, stir toggle switch 5, power line between standard SD card interface 4 with miniSD plug 2 is communicated with, and SD signal is to usb signal change-over circuit 6 power-off, and standard SD card interface 4 obtains electric, thus the data circuit between standard SD card interface 4 and miniSD plug 2 is connected, portable set can carry out data access to standard SD card.And when selecting miniSD card as Memory Extension equipment, both directly can connect portable set, and also by the utility model equipment connection, when utilizing the utility model equipment, miniSD having been linked and connects SD-miniSD adapter 7.
