Abstract
A double-side available USB flash disk structure is disclosed. The double-side available USB flash disk structure comprises a USB flash disk body and metal contacts arranged on the upper and lower planes of the USB flash disk body; a flash memory and a digital circuit are welded on a circuit board and packaged in the USB flash disk body; the double-side available USB flash disk structure is characterized in that a power supply input connector and a data input connector on the circuit board are connected with the metal contacts on the upper and lower planes of the USB flash disk body; a through hole is formed in the back end of the USB flash disk body; a lower inclined plane and an upper inclined plane are arranged at the front end of the USB flash disk body; an upper groove is formed in the upper plane of the USB flash disk body while a lower groove is formed in the lower plane of the USB flash disk body; an a-plane first power supply metal contact, an a-plane first data metal contact, an a-plane second data metal contact and an a-plane second power supply metal contact are mounted in the upper groove; and a b-plane first power supply metal contact, a b-plane first data metal contact, a b-plane second data metal contact and a b-plane second power supply metal contact are mounted in the lower groove. The double-side available USB flash disk can be used normally by being inserted in an USB socket without distinguishing the front plane and the back plane of the USB flash disk, so that the double-side available USB flash disk can greatly improve working efficiency.
Description
Technical field
The present invention relates to digital storage equipment, be specifically related to a kind of regardless of positive and negative slotting arbitrarily U-disk structure.
Background technology
In the use procedure of USB flash disk, the positive and negative of USB flash disk is often easily mixed up and is confused, and causes user's contraposition repeatedly.Particularly use the USB flash disk of plug not with iron-clad, if anti-inserted, cannot transmission information, again insert after needing user again to extract.For identifying the computer that USB flash disk is slow, user's repeatedly plug may be caused, very inconvenient.
Summary of the invention
For the deficiency that prior art exists, the present invention provides a kind of and inserts U-disk structure arbitrarily regardless of positive and negative.
To achieve these goals, the technical solution used in the present invention is as follows: a kind of regardless of positive and negative slotting arbitrarily U-disk structure, comprise flash disk body and the metal contact piece being arranged on flash disk body upper and lower surface, flash memory and digital circuit on circuit boards soldered and be encapsulated in flash disk body, it is characterized in that: the power supply input adapter on circuit board is connected with the metal contact piece of data input adapter with flash disk body upper and lower surface; Flash disk body rear end is provided with through hole, front end is provided with lower inclined plane and ramp, upper groove is provided with above flash disk body, be provided with low groove below, a face first power Metal contact, a face first data metal contact piece, a face second data metal contact piece and a face second source metal contact piece are installed in upper groove, in low groove, are provided with b face first power Metal contact, b face first data metal contact piece, b face second data metal contact piece, b face second source metal contact piece.
Lower inclined plane and ramp are mutually vertical, the degree of depth of lower upper groove is greater than the thickness of a face first power Metal contact, a face first data metal contact piece, a face second data metal contact piece and a face second source metal contact piece, and the degree of depth of low groove is greater than the thickness of b face first power Metal contact, b face first data metal contact piece, b face second data metal contact piece, b face second source metal contact piece.
A face first power Metal contact, with b face first power Metal contact conducting, with other metal contact piece not conductings, a face first data metal contact piece and b face first data metal contact piece conducting, with other metal contact piece not conductings, a face second data metal contact piece and b face second data metal contact piece conducting, with other metal contact piece not conductings, a face second source metal contact piece and the second source metal contact piece conducting of b face, with other metal contact piece not conductings.
Adopt technical solution of the present invention, there is following beneficial effect:
1) the lower upper groove of the present invention's setting, can prevent the metal sheeting arranged in current USB socket from touching metal contact piece and causing short circuit phenomenon;
2) the present invention inserts in USB socket and just can normally use, and does not need the positive and negative distinguishing flash disk, can greatly increase work efficiency.
