Abstract
The invention relates to a USB (universal serial bus) flash disk comprising a disk body, PCBs (printed circuit boards), a lock key, a No.1 LED (light-emitting diode), a No.2 LED (light-emitting diode), a No.3 LED (light-emitting diode) and a No.4 LED (light-emitting diode); the upper body surfaces of two ends of the disk body are provided with PCBs respectively; the PCBs both integrally extend to the lower body surfaces of two ends of the disk body and are embedded into the disk body at the terminals of two ends of the disk body by adopting an embedded mode; the No.1 LED,the No.2 LED, the No.3 LED and the No.4 LED are all installed on the disk body and are connected with a memory device in the USB flash disk; the lock body is arranged at the side edge of the disk body. The upper body surface and the lower body surface at two ends of the USB flash disk provided by the invention are both provided with the PCB boards, so that the PCB boards are convenient to insert into USB interfaces of a computer case; the damage to the USB flash disk, caused by unnecessary errors in the insertion process, is reduced; the service life of the USB flash disk is prolonged; the LED lamps on the disk body are all connected with the memory device in the disk body, and the internal memory state is convenient to observe.
Description
Technical field
The present invention relates to a kind of External memory equipment of computing machine, relate in particular to a kind of USB flash disk.
Background technology
The most crucial position of USB flash disk just is its movement, movement comprises a pcb board+master control+crystal oscillator+capacitance-resistance electric capacity+USB head+LED head+FLASH (flash memory) chip, what in use directly contact computer USB interface is pcb board, to use contact site the most frequently, be tending towards in prior art is hidden in mostly to the use of USB flash disk pcb board design, so often bring the inconvenience of use and can't promptly and accurately patch, existing USB flash disk also ubiquitous a kind of drawback is exactly content size and the remaining storage space that clearly cognition specifically deposits in coiling.
Summary of the invention
In view of this, be necessary to provide a kind of being convenient to patch on the USB interface of computer, and be convenient to the USB flash disk of clearly cognitive inner residue memory space.
The present invention realizes like this, a kind of USB flash disk comprises disk body, pcb board, locking key, a LED lamp, No. two LED lamps, No. three LED lamps, No. four LED lamps, the upper dignity at the two ends of described disk body respectively is provided with described pcb board, described pcb board expansion body extension is to the lower dignity at the two ends of described disk body, and described pcb board is in employing embedded mode in the end at the two ends of described disk body is embedded in described disk body, a described LED lamp, described No. two LED lamps, described No. three LED lamps, described No. four LED lamps are installed on described disk body, and be connected with the memory device of described USB flash disk inside, described locking key is arranged on the side of described disk body.
Further, described body structure is symmetrical up and down.
Further, a described LED lamp, described No. two LED lamps, described No. three LED lamps, described No. four LED lamps all are connected with described pcb board.
The advantage of USB flash disk provided by the invention is: the upper and lower dignity in the two ends of USB flash disk of the present invention all is provided with pcb board, is convenient to patch on the USB interface of computer housing, reduces the unnecessary damage to USB flash disk that patches the mistake in process and cause, the serviceable life of strengthening USB flash disk.
By a LED lamp, No. two LED lamps, No. three LED lamps, No. four LED lamps are set on disk body, cut all and be connected with the memory device of disk body inside, be convenient to observe the storage inside state, mean when No. one the LED lamp is bright that memory space is that 25%, No. two LED lamp means that memory space is that 50%, No. three LED lamp means that memory space is that 75%, No. four LED lamp means that memory space is 100% when bright when bright when bright.
By in the disk body side, locking key being set, without USB flash disk the time, locking key is closed, effectively the safety of the internal file of protection.
The accompanying drawing explanation
The vertical view that Fig. 1 is USB flash disk of the present invention.
The side view that Fig. 2 is Fig. 1.
The side view that Fig. 3 is Fig. 2.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
See also Fig. 1, Fig. 2 and Fig. 3, the vertical view that wherein Fig. 1 is USB flash disk 100 of the present invention, the side view that Fig. 2 is Fig. 1, the side view that Fig. 3 is Fig. 2.
Described USB flash disk 100 comprises disk body 10, pcb board 20, locking key 30, a LED lamp 1, No. two LED lamps 2, No. three LED lamps 3, No. four LED lamps 4, upper honorable 11 of the two ends of described disk body 10 respectively are provided with described pcb board 20, described pcb board 20 expansion body extensions are to lower honorable 12 of the two ends of described disk body 10, and described pcb board 20 is in employing embedded mode in the end at the two ends of described disk body 10 is embedded in described disk body 10, a described LED lamp 1, described No. two LED lamps 2, described No. three LED lamps 3, described No. four LED lamps 4 are installed on described disk body 10, and be connected with the memory device of described USB flash disk 100 inside, described locking key 30 is arranged on the side of described disk body 10.
Described disk body 10 structures are symmetrical up and down, and a described LED lamp 1, described No. two LED lamps 2, described No. three LED lamps 3, described No. four LED lamps 4 all are connected with described pcb board 20.
In sum, the upper and lower dignity in the two ends of USB flash disk of the present invention all is provided with pcb board, is convenient to patch on the USB interface of computer housing, reduces the unnecessary damage to USB flash disk that patches the mistake in process and cause, the serviceable life of strengthening USB flash disk.
By a LED lamp, No. two LED lamps, No. three LED lamps, No. four LED lamps are set on disk body, cut all and be connected with the memory device of disk body inside, be convenient to observe the storage inside state, mean when No. one the LED lamp is bright that memory space is that 25%, No. two LED lamp means that memory space is that 50%, No. three LED lamp means that memory space is that 75%, No. four LED lamp means that memory space is 100% when bright when bright when bright.
By in the disk body side, locking key being set, without USB flash disk the time, locking key is closed, effectively the safety of the internal file of protection.
