Abstract

The utility model relates to the technical field of digital memory, in particular to a portable USB memory, which comprises an upper cover, a lower cover and a PCB board; a memory IC is arranged on the PCB board, the back end of the PCB board is arranged in the room which is formed by covering the upper cover and the lower cover, the front end is out of the upper cover and the lower cover; a golden finger is printed on the end face of PCB board front and matched to the contact spring strip of the standard USB female base. A connection joint is extended protuberantly in the lower cover front; rib strips are formed on the two sides of the top end of the connection joint to prevent reverse intercalation. By adopting the technical proposal, the utility model can spare the USB socket jointed on the USB memory, reduce the size of the USB memory remarkably and form a super-small and super- thin structure.

Description

A kind of Portable USB storer

Technical field:

The utility model relates to digital memory technology field, refers in particular to a kind of Portable USB storer.

Background technology:

At present, along with fast development of information technology, replace traditional computer floppy drive trend that has been inevitable with the Portable USB storer.The consideration of carrying for convenience, people always wish that this movable storage device (USB storage) can do the smaller the betterly.But at present used USB storage makes its size be difficult to reduce because the USB socket of the standard of must burn-oning could be used, and still has inconvenience in the use.

Summary of the invention:

The purpose of this utility model just is to provide at the deficiencies in the prior art part a kind of simple in structure, USB storage that profile is small and exquisite.

For achieving the above object, the utility model comprises: loam cake, lower cover and pcb board, pcb board is provided with storage IC, the rear end of pcb board is arranged on loam cake and lower cover covers in the space of back formation, its front end then stretches out in outside loam cake and the lower cover, is printed on the golden finger that matches with the contact spring of standard USB female seat on the end face of pcb board front end.

As improvement of the technical scheme, the front end of lower cover has also protruded out a junction, and this connecting portion is fitted on the lower surface of pcb board, and constitutes the connection-peg that cooperates with the USB female seat jointly with the front end of pcb board, the phenomenon that fractures occurs to prevent the pcb board front end.

As further improvement in the technical proposal, the both sides of described connecting portion upper surface form the rib that counnter attack is inserted respectively.

Both sides all form the reinforcement that is used for fixing pcb board in described loam cake and the lower cover.

After adopting technique scheme, the utility model can save traditional USB socket that is welded on the USB floppy drive, thereby can reduce the volume of USB floppy drive significantly, reaches extra small, ultra-thin structure; And the setting of the reinforcement in loam cake and the lower cover then can make pcb board can be fixed and can not rock; Be arranged on the rib of both sides, connection-peg upper surface, can prevent that then the anti-phenomenon of inserting from appearring in USB storage.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Accompanying drawing 1 is a three-dimensional combination figure of the present utility model

Accompanying drawing 2 is a three-dimensional exploded view of the present utility model

Embodiment:

The following stated only is a preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See shown in accompanying drawing 1 and the accompanying drawing 2, the utility model comprises: loam cake 10 that hollow is box-like and lower cover 20 and are provided with the pcb board 30 of storage IC40, the front end of lower cover 20 has protruded out a junction 21, and the both sides of connecting portion 21 upper surfaces form the rib 60 that counnter attack is inserted respectively;

The rear end 31 of pcb board 30 is arranged on loam cake 10 and lower cover 20 covers in the space of back formation, it is outer concordant with the upper surface of connecting portion 21 with lower cover 20 that 32 of its front ends stretch out loam cake 10, and constitute the connection-peg 50 that cooperates with the USB female seat jointly, be printed on the end face of pcb board 30 front ends 32 and the contacted golden finger 33 of the contact spring of standard USB female seat.

In order to prevent that pcb board 30 from rocking, form the reinforcement 70 that is used for fixing pcb board 30 in loam cake 10 and the lower cover 20 respectively, after loam cake 10 and lower cover 20 covered, the reinforcement 70 in it can be fixed pcb board 30, makes it can not rock.

The material of loam cake 10 and lower cover 20 can be selected various plastic cement or metal material for use, and its shape also can be other shape except box-like, and is attractive in appearance for making it in addition, also can add inscription plate or some other decoration on loam cake 10 and the lower cover 20.

During use, after connection-peg 50 inserted in the USB female seat, the golden finger 33 on the pcb board 30 can contact with the contact spring of USB female seat, thereby stores work accordingly.
