Abstract
The utility model relates to a mobile terminal data expansion memory which comprises a data expansion memory of a mobile terminal; the data expansion memory comprises a shell used for containing a cavity; the cavity is internally provided with a printed circuit board (PCB) which is provided with a control circuit and a memory chip connected with the control circuit; the shell is provided with an interface which at least consists of two power lines and two control lines; and the power lines and the control lines of the interface are respectively and electrically connected with the control circuit arranged on the PCB. Compared with the prior art, after a minitype universal serial bus (USB) interface is adopted, on the one hand, the data expansion memory can be ensured to be more attractive together with the mobile terminal matched with the data expansion memory, and on the other hand, data can be more conveniently exported and imported, so that inconvenient carrying and use caused by reading data by a data line can be avoided; meanwhile, the defect that the data in one terminal can be read through another terminal by powering off when an internal expansion interface is adopted can be avoided.
Description
Technical field
The utility model relates to the electronic information storage technical field, particularly a kind of mobile terminal data extended memory.
Background technology
Existing portable mobile termianl, for example electronic product such as smart mobile phone, dull and stereotyped electroplax is typically provided with the data expansion interface; Make things convenient for the user to import and export data; But this portable terminal since volume little and attractive in appearance because of former, the USB interface that do not set up standard usually for example adopts MINI type USB interface; The user need be connected with computer with data line when transferring its inner data or data in use usually; Realize data transmission, cause and use inconvenience, need carry data line simultaneously thereby also cause and carry inconvenience.
The utility model content
The technical matters that the utility model mainly solves provides a kind of mobile terminal data extended memory; This mobile terminal data extended memory can directly read from this storer when using, and that causes in the time of can avoiding through the data line reading of data carries and use inconvenience.
In order to address the above problem; The utility model provides a kind of mobile terminal data extended memory; This mobile terminal data extended memory comprises: the mobile terminal data extended memory; Comprise the shell that is provided with storage cavity, in this cavity, establish pcb board, this pcb board is provided with control circuit and is connected storage chip with control circuit; Said shell is provided with at least the interface by two power leads and two control line group lines, power lead on this interface and control line respectively with pcb board on control circuit be electrically connected.
Preferably, said interface is MINI USB or Micro USB interface.
Preferably, said extended memory also comprises at least one standard USB interface.
The utility model mobile terminal data extended memory; The mobile terminal data extended memory; Comprise the shell that is provided with storage cavity, in this cavity, establish pcb board, this pcb board is provided with control circuit and is connected storage chip with control circuit; Said shell is provided with at least the interface by two power leads and two control line group lines, power lead on this interface and control line respectively with pcb board on control circuit be electrically connected.With present compared with techniques; Owing to adopt Mini USB or Micro USB interface can make the portable terminal that cooperates with it more attractive in appearance on the one hand; More convenient in derivation or importing data on the other hand; Can directly from this storer, read during use, and needn't adopt data line to connect computer, that causes when avoiding through data line by the computer reading of data carries and uses inconvenience.
Description of drawings
Fig. 1 is the utility model mobile terminal data extended memory example structure synoptic diagram.
Below in conjunction with embodiment, and with reference to accompanying drawing, realization, functional characteristics and the advantage of the utility model purpose is described further.
Embodiment
As shown in Figure 1, the utility model provides a kind of mobile terminal data extended memory embodiment.
This mobile terminal data extended memory comprises: the shell 1 that is provided with storage cavity; In this cavity, establish pcb board 2; This pcb board 2 is provided with control circuit (accompanying drawing does not indicate) and is connected storage chip 3 with control circuit; Said shell 1 is provided with at least the interface 4 by two power leads 41 and 42 groups of lines of two control lines, the power lead 41 on this interface 4 and control line 42 respectively with pcb board 2 on control circuit be electrically connected.For example this interface can be made up of two power leads and two control lines, also can comprise the power supply that is used to charge.Said interface is a MINI type USB interface.
With present compared with techniques; Owing to adopt MINI type USB interface can make the portable terminal that cooperates with it more attractive in appearance on the one hand; More convenient in derivation or importing data on the other hand; That causes when avoiding through the data line reading of data carries and uses inconvenience, needs powered-down could the data in the terminal be read through another terminal in the time of can avoiding adopting the internal extended interface simultaneously.
In the above-described embodiments, said extended memory also comprises at least one standard USB interface, for example can establish the USB interface of one, two or three standard.
The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
Claims (3)
1. the mobile terminal data extended memory comprises the shell that is provided with storage cavity, in this cavity, establishes pcb board, and this pcb board is provided with control circuit and is connected storage chip with control circuit, it is characterized in that:
Said shell is provided with at least the interface by two power leads and two control line group lines, power lead on this interface and control line respectively with pcb board on control circuit be electrically connected.
