Abstract
The utility model discloses a USB flash memory card, which comprises control chips, flash memory chips and a USB interface, wherein bare chips of the control chips and the flash memory chips are installed on a PCB board in an overlapped way; the PCB board is installed on the USB interface; the other end of an inserting end is provided with a retaining wall. When the USB flash memory card needs to be used for the digital equipment of digital cameras, mobile phones, etc., the USB flash memory card can be directly inserted in the digital equipment; when the utility model reads data, a special card reader does not need and the utility model can be directly inserted in computers. Furthermore, the USB flash memory card can only be inserted in the computers from the correct end and can not be inserted in the computers from the other end and avoids being inserted from the other end by accident to cause a power cord of the flash memory card and a groundwire to be inserted wrong to result in the burning up of the flash memory card. In addition, the utility model can enable the USB flash memory card to be convenient when pulled out from the computers; because the USB flash memory card is small, the USB flash memory card can be carried with portable computers and does not need to be pulled out when is applied to the portable computers. Thus, the utility model prolongs service life and prevents loss.
Description
Technical field
The utility model relates to a kind of storer, refers to a kind of USB flash memory card that computer also can directly insert digital equipment that both can directly connect especially.
Background technology
As shown in Figure 1, the flash card form that is applied to digital equipment in the market is numerous, and CF card, SM card, mmc card, SD card etc. are arranged, these flash cards are incompatible to each other, also incompatible USB interface of while, and it is in use, special-purpose card reader must be arranged, otherwise can't connect computer.And existing USB flash disk, it is to be made of USB interface and electronic circuit two parts, adds Package casing, as shown in Figure 2, its volume is bigger, during use, electronic circuit except that USB interface part can't insertion equipment in, so it can only directly connect computer and can not directly insert in the digital equipment; And because its volume is bigger, in the time of in being applied in laptop computer, when not using, generally all can transfering to and carry and can together not carry, like this, reduced in its life-span, lose easily on the other hand with portable computer.
The utility model content
Fundamental purpose of the present utility model is to provide a kind of USB flash memory card that not only can directly connect computer but also can directly insert digital equipment.
Secondary objective of the present utility model is to provide a kind of anti-inserted USB flash memory card that prevents.
For achieving the above object, solution of the present utility model is: a kind of USB flash memory card, it mainly comprises: control chip, flash chip, USB interface, wherein: the nude film of control chip and flash chip is overlapping to be installed on the pcb board, and described pcb board is installed on the USB interface.
The nude film of described control chip and flash chip is installed in the two sides of pcb board respectively, and the power lead of USB interface, data line, ground wire are connected on the pcb board.
The overlapping one side that is installed in pcb board of the nude film of described control chip and flash chip, pcb board is installed in the back side of USB interface, and it connects with power lead, data line, the ground wire of USB interface.
The overlapping one side that is installed in pcb board of the nude film of described control chip and flash chip, the another side of pcb board is provided with power lead, data line, ground wire.
Described USB flash memory card, its other end in insertion end is provided with the retaining wall.
Described retaining wall is the projection that is located at other end top.
Described retaining wall is the block that is located at other end both sides.
After adopting said structure, when this USB flash memory card being applied to digital equipments such as digital camera, MP3 player, mobile phone when needs, because it is to be installed on the pcb board the nude film of control chip and flash chip is overlapping, pcb board is installed on the USB interface again, so its volume is less, can directly insert in the digital equipment, and because it is a USB interface, when read data, do not need special-purpose card reader, can directly insert in the computer; The setting of retaining wall can only and can not inserted this USB flash memory card from correct end insertion computer from the other end, has avoided inserting power lead and the ground wire wrong plug that makes flash card, the consequence that causes flash card to burn from the other end because of carelessness; In addition, the setting of retaining wall, it is comparatively convenient that USB flash memory is stuck in when transfering to computer; Moreover, because this USB flash memory card is less, when it is applied in laptop computer,, also need not transfers at any time and can together carry with laptop computer even do not use, can prolong its serviceable life can prevent from again to lose because of carelessness; With commonly use flash card or USB flash disk is compared, the utility model not only can directly connect computer but also can directly insert digital equipment, and easy to use can be not anti-inserted.

Embodiment
Shown in Fig. 3 to 7, the utility model discloses a kind of USB flash memory card, it mainly comprises: control chip 1, flash chip 2, USB interface 3, wherein:
Overlapping being installed in respectively on the pcb board 4 of nude film of control chip 1 and flash chip 2, described pcb board 4 is installed in the back side of USB interface 3.
As shown in Figure 3, the overlapping two sides that is installed in pcb board 4 of nude film of control chip 1 and flash chip 2, the power lead 33 of USB interface 3, data line 34, ground wire 35 are connected on the pcb board 4, and crystal oscillator 6 also is installed on the pcb board 4.
As shown in Figure 4, the overlapping one side that is installed in pcb board 4 of nude film of control chip 1 and flash chip 2, the power lead 33 of USB interface 3, data line 34, ground wire 35 are connected on the pcb board 4, and crystal oscillator 6 also is installed on the pcb board 4.
As shown in Figure 5, the overlapping one side that is installed in pcb board 4 of nude film of control chip 1 and flash chip 2, power lead 33, data line 34, ground wire 35 are directly installed on the another side of pcb board 4, and pcb board 4 is inlaid in the upper end of USB interface 3, and crystal oscillator 6 is installed on the pcb board 4.
