Description
Technical field
The present invention relates to a kind of universal serial bus (USB) memory device, particularly relate to universal serial bus (USB) memory device of microminiaturization.
Background technology
Computer strengthens its function by connecting multiple external peripheral.This may involve any amount of periphery.In order to comply with the more and more modular trend of computer, develop a kind of universal serial bus (USB) interface standard jointly.The USB standard definition high speed sequence data interface between computer and the optional equipment, for example keyboard, printer, scanner and second storage facilities, wherein second storage facilities comprises floppy drive, Winchester disk drive and the solid-state second storage machine etc.In the computer of USB port was arranged, these equipment can be added into or remove in computer booting be carried out.
Because it is more and more universal to have the hand-held computer equipment of USB port, as mobile computer, flat computer and PDA(Personal Digital Assistant), USB interface provides the elasticity capacity of hand-held computer user plug and play.That is to say that the user of mobile computer can carry the ancillary equipment of many outsides, and when needing to use, simply required external peripheral is being inserted into hand-held computer equipment.
Recently, the flash card that contains USB connector is also started selling.This USB flash memory card does not need special reader and can plug USB connector on personal computer (PC) or other main process equipment.These USB flash memory cards can replace floppy disk to be used and ripe well known, and as the carry-on dish of usb key (key) type, USB thumb type (thumb) is dish with oneself, and the carry-on dish of many different titles.These USB flash memories are stuck in that storage capacity exceeds ten diskette sheets under the area that is no more than the postage-stamp-sized scope.
Fig. 1 shows that a kind of convex that is incorporated on the flash card circuit substrate according to prior art approaches USB connector; And the profile of AA-AA in Fig. 2 displayed map 1.As depicted in figs. 1 and 2, the carry-on dish of USB pen type of microminiaturization has comprised the metallic conduction shell 11 and electronic printing circuit board combination (PCBA) 12 of a plurality of directivity depressions 111, is used to provide the storage internal memory.Moreover, also because electronic printing circuit board combination (PCBA) 12 often thickness do not reach requirement, cause and read and store difficulty.Therefore, must be dependent on other object increases height, just can read or store internal memory.
So the carry-on dish of USB pen type of microminiaturization has also comprised thin slice 13, is arranged between metallic conduction shell 11 and the PCBA12, be used for making PCBA 12 driving fits at metallic conduction shell 11, wherein thin slice 13 available metal sheets or plastic sheet are made.Thin slice 13 is the spaces that are used for filling up between metallic conduction shell 11 and PCBA12.In any case in fact, thin slice 13 is difficult to be assembled in the space between metallic conduction shell 11 and the PCBA12.Therefore, the carry-on dish of USB pen type of prior art is difficult to effectively in addition microminiaturization.
