Abstract

The utility model discloses a Micro USB (universal serial bus) plug type storage disc which comprises a Micro USB plug, a shell and a storage chip. The storage chip is arranged in the shell; the Micro USB plug is fixedly connected with the shell; and the wire connecting terminal in the Micro USB plug is correspondingly connected with the wire connecting terminal of the storage chip. The Micro USB plug of the Micro USB plug type storage disc can be inserted into the Micro USB socket of an OTG mobile phone so that the OTG (On-The-Go) mobile phone can detect a grounded ID (identity) signal, identify the Micro USB plug type storage disc and further read and write the Micro USB plug type storage disc. The Micro USB plug type storage disc disclosed by the utility model is an external storage disc which is smaller than the USB flash disk, can be directly inserted into the Micro USB socket of the OTG mobile phone to use, solves the problem that the traditional OTG mobile phone can not read and write the external storage disc such as the USB flash disk and is convenient to use and carry. The Micro USB plug type storage disc can be also used for other equipment with the Micro USB plug in addition to the mobile phone.

Description

Micro USB plug formula storage disks
Technical field
The utility model relates to a kind of storage disks, relates in particular to a kind of Micro USB plug formula storage disks.
Background technology
OTG is the abbreviation of On-The-Go, is the technology that developed recently gets up, and announced by USB Implementers Forum Dec 18 calendar year 2001, is mainly used in the connection between various equipment or mobile device, carries out exchanges data.Particularly PDA, mobile phone, consumer devices.Change the inconvenience such as exchanges data between the storage card of the multiple different systems connectors of equipment room such as mobile phone, digital camera, video camera, printer.
Micro USB is a portable version of USB 2.0 standards, the Mini USB interface of using than present part mobile phone is less, Micro-USB is the specification of future generation of Mini-USB, is formulated on January 4th, 2007 by USB standardization body U.S. USB Implementers Forum (USB-IF) and finishes.The mobile phone that uses Micro USB socket and have the OTG function has more and more become the main flow type of cell phone.There is following defective in data transmission between OTG mobile phone and other storage facilities at present: USB flash disk and other storage facilities can not directly use at the OTG mobile phone, during use the OTG conversion line must be arranged, the relative mobile phone volume of USB flash disk and other storage facilities is larger, connecting the OTG conversion line, not only to affect mobile phone attractive in appearance again, and use, carry equal inconvenience.
The utility model content
The purpose of this utility model provides a kind of Micro USB plug formula storage disks with regard to being in order to address the above problem, and this storage disks can directly connect with the equipment of Micro USB socket such as OTG mobile phone.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Micro USB plug formula storage disks described in the utility model comprises the storage chip in Micro USB plug, housing and the housing, described Micro USB plug is fixedly connected with described housing, the terminals in the described Micro USB plug and the corresponding connection of terminals of described storage chip.
During use, the Micro USB plug of storage disks described in the utility model is inserted on the Micro USB socket of OTG mobile phone, the OTG mobile phone just can detect the ID signal of ground connection, just can identify storage disks, and then can read and write storage disks.
Particularly, terminals in the described Micro USB plug comprise VBUS terminals, Date-terminals, Date+ terminals, GND terminals and ID terminals, the terminals of described storage chip comprise VBUS terminals, Date-terminals, Date+ terminals and GND terminals, the corresponding connection of terminals of the same names in the terminals of described storage chip and the described Micro USB plug, the interior ID terminals of described Micro USB plug are connected with the GND terminals.
The beneficial effects of the utility model are:
Storage disks described in the utility model is the external reservoir smaller and more exquisite than USB flash disk, can directly be inserted on the Micro USB interface of OTG mobile phone to use, solved the OTG mobile phone can not the similar USB flash disk of direct read/write etc. the problem of external reservoir, easy to use with carry.Storage disks described in the utility model also can be used for other equipment with Micro USB socket beyond the mobile phone.
Description of drawings
Fig. 1 is the stereographic map of Micro USB plug formula storage disks described in the utility model;
Fig. 2 is the front view of Micro USB plug formula storage disks described in the utility model;
Fig. 3 is the electrical connection graph of Micro USB plug formula storage disks described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Such as Fig. 1, Fig. 2 and shown in Figure 3, Micro USB plug formula storage disks described in the utility model comprises the storage chip 3 in MicroUSB plug 1, housing 2 and the housing, and MicroUSB plug 1 is fixedly connected with housing 2; Terminals in the Micro USB plug 1 comprise VBUS terminals, Date-terminals, Date+ terminals, GND terminals and ID terminals, the terminals of storage chip 3 comprise VBUS terminals, Date-terminals, Date+ terminals and GND terminals, the corresponding connection of terminals of the same names in the terminals of storage chip 3 and the Micro USB plug 1, Micro USB plug 1 interior ID terminals are connected with the GND terminals.The profile of the Micro USB plug 1 among the Micro USB plug 1 among Fig. 1 and Fig. 2 and Fig. 3 is different, and this is because the Micro USB plug 1 among Fig. 3 only is synoptic diagram, is mainly used in showing electric connection structure.
In conjunction with Fig. 1 and Fig. 2, during use, the Micro USB plug 1 of storage disks described in the utility model is inserted on the Micro USB socket of OTG mobile phone, the ID signal that the OTG mobile phone just can detect by the ID terminals in the Micro USB plug 1 ground connection is the signal of GND terminals, just can identify storage disks, and then can read and write storage disks.
