Description

A kind of four-in-one OTG flash disk

Technical field

A kind of Portable type mobile storage device field, and in particular to four-in-one OTG flash disk.

Background technique

Flash disk is a kind of miniature high capacity movable storage device without phisical drive, and the storage medium used is sudden strain of a muscle (Flash Memory) memory is deposited, one of the most common flash disk is the USB flash memory using standard USB-Type A interface Disk (abbreviation USB flash disk), in addition to this there are also the dedicated flash memories using particular interfaces such as IEEE1394, E-SATA, Thunderbolt Disk.Compared to other movable storage devices (such as diskette sheet, mobile hard disk etc.), flash disk have it is small and exquisite it is portable, performance is stable, The advantage that dustproof and waterproof, antidetonation are diamagnetic, memory space is big, transmission speed is fast, therefore flash disk is widely used.

With universal and USB OTG technology (the USB On-The- of the mobile intelligent terminals such as smart phone, tablet computer Go further development), flash disk are able to be detached from the limitation of host, directly carry out data transmission with mobile intelligent terminal, significantly The application scenarios for having expanded flash disk also significantly increase the efficiency of study, work.

However the interface of mainstream mobile intelligent terminal (especially smart phone and tablet computer) on the market is usual at present There are three classes --- the Lightning type interface, novel of the micro USB Type Type B interface of common Android machine, Macintosh The USB Type c-type interface of Android machine or apple plate, but common OTG flash disk only one USB Type A type Interface and an a certain mobile terminal interface, can no longer meet and use on different mobile intelligent terminals, so that different It can not easily be transmitted between the terminal of interface, shared data.

For example patent CN204407647U discloses a kind of OTG data line, which has an ECU connectors and one A mobile phone connector, but be only capable of being adapted to a kind of handset port, but also need external by USB flash disk or storage card etc. is inserted into socket Storage equipment just can carry out data transmission or browse.For another example patent CN203055453U discloses a kind of Multifunctional U disc, can It is used on computer or mobile phone, but is not able to satisfy the demand of distinct interface mobile terminal transmission data on the market, and due to Its Interface integration is on a small-sized card, and interface is spaced closely together, and there are problems that interfering when in use, and pole is not It is convenient.
