Description
Technical field
The utility model belongs to computer fittings field, is specifically related to a kind of Multifunctional USB interface expanding unit.
Background technology
The development of computer technology and the universal of internet, make computing machine become the requirement of government organs and enterprises and institutions' office, also make infotech be dissolved into the every aspect of ordinary people's life.For the USB interface that computer is limited, the various equipment needing USB interface to connect, as keyboard, mouse, storage card, USB flash disk, portable hard drive etc. often allow user puzzle one's brains owing to not having enough jacks.
The major defect of existing USB interface expanding unit is as follows: one, the interface arrangement of part desktop computer or notebook computer closely, after inserting a USB interface, affects the insertion of another USB device, two, existing USB interface expanding unit is more single due to function, can not meet customer need, as the read-write of contact person in SIM cards of mobile phones and information, the high speed of part high-end cameras or industrial control equipment, the read-write of jumbo CF card and day by day universal intelligent terminal Micro SD card, the read-write capability of SD card, three, lack accessory power supply, because the equipment of part usb expansion device access is when two or more, especially at access relatively high power equipment, during as 3.5 inch portable hard drive, access a mouse again to carry out operating and just there will be obviously Caton phenomenon, if portable hard drive is also carrying out read-write operation simultaneously, so also likely can cause and read and write unsuccessfully.Four, auxiliary power interface is DC round mouth, inconvenient.
Utility model content
Technical problem to be solved in the utility model overcomes above-mentioned defect, provides one to be easy to carry, and supports the USB interface expanding unit of plurality of specifications storage card.
To achieve these goals, the utility model is achieved by the following technical solutions:
A kind of Multifunctional USB interface expanding unit, comprise housing 1, housing is provided with some USB interface 2 and SIM card slot 3, Micro sd card slot 4, SD card slot 5, CF card slot 6, auxiliary power supply interface 7, housing 1 inside is provided with surface-mounted integrated circuit 8.
Described USB interface comprises a male mouth of USB (21) and two female mouths (22) of USB, is standard USB3.0 Dual-face inserting interface, lays respectively on two relative sides of housing 1.
The public mouth 21 of described USB is connected with data line 9, and data line 9 end connects public mouth 21 side of retractor device 10, USB and is provided with auxiliary power supply interface 7.
Described SIM card slot and CF card slot are positioned at the same side.
Described Micro sd card slot and SD card slot are positioned at the CF card slot opposite side relative with SIM card slot side.
Described auxiliary power supply interface is Micro USB interface.
Its beneficial effect is: the utility model is while meeting and expanding the female mouths of two USB3.0, by auxiliary power supply interface being changed into the conventional Micro usb interface of mobile phone, and add the read-write capability of plurality of specifications storage card, achieve the possibility of described plurality of devices Simultaneous Stabilization transmission data, improve the utilization factor of user computer USB interface, for the stable transfer of user data provides guarantee.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model front view.
Fig. 3 is the utility model left view.
Shown in figure: the male mouth 21 of housing 1, USB interface 2, USB, USB female mouth 22, SIM card slot 3, Micro sd card slot 4, SD card slot 5, CF card slot 6, auxiliary power supply interface 7, surface-mounted integrated circuit 8, data line 9, retractor device 10.
Embodiment
Below in conjunction with accompanying drawing 1,2,3, structure of the present utility model and beneficial effect thereof are further illustrated.
Example
As shown in the figure, pull the public mouth 21 of USB from housing 1 one end thus take data line 9 out of to applicable length, more male for USB mouth 21 being connected on the female mouth of computer USB, namely achieving described usb expansion device and the connection of computer.SIM card slot 3, SD card, Micro SD card, CF card, SIM card, portable hard drive or the mouse-keyboard etc. that will carry out reading and writing access the female mouth 22 of corresponding Micro SD card slot, SD card slot 5, CF card slot 6 or USB on demand again, namely carry out data read-write operation by computer to access relevant device.When the equipment connected is in two or more, the cellular phone data line of Micro usb interface can be used as supply lines, after one end access 5V power supply, Micro usb interface be inserted auxiliary power supply interface 7, to make described usb expansion device energy steady operation.
Above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, not departing under prerequisite of the present utility model, can also make some distortion and improvement, these all belong to the protection domain of this practicality.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
