`UNIVERSAL SERIAL BUS (USB) MEMORY
`PLUG
`
`FIELD OF THE INVENTION
`
`The present invention relates to a Universal Serial Bus
`(USB) memory apparatus, and more particularly, to a minia-
`turized Universal Serial Bus (USB) memory apparatus.
`
`BACKGROUND OF THE INVENTION
`
`The capabilities of a computer are maximized by utilizing
`a variety of external peripheral devices that are connected to
`the computer. This may involve any number ofperipherals. In
`response to computers becoming more modular, a Universal
`Serial Bus (USB) interface standard was jointly developed.
`The USB standard defines a high-speed serial data interface
`between a computer and add-on devices, such as keyboards,
`printers, scarmers and secondary storage devices, including
`floppy disk drives, hard disk drives, and solid-state secondary
`storage drives. In computers that have USB compliant ports,
`such devices can be added or removed while the computer is
`powered up and running.
`With the growing popularity of portable computing
`devices having USB compliant ports, such as notebook, tablet
`computers, and personal digital assistants (PDA), the USB
`ports afford on-the-go flexibility to a user of the portable
`computing device. That is, the user of a notebook can carry
`multiple external peripheral devices, and simply plug the
`needed external peripheral device into the portable comput-
`ing device when needed.
`Recently, flash memory cards are also being sold that con-
`tain a USB connector. Such USB-flash memory cards do not
`require a specialized reader but can be plugged into a USB
`connector on a personal computer (PC) or other hosting
`device. These USB-flash memory cards can be used in place
`of floppy disks and are known as USB key drives, USB thumb
`drives, and a variety of other names. These USB-flash cards
`can have a capacity of more than ten floppy disks in an area
`not much larger than a large postage stamp.
`FIG. 1 shows an assembly of a male slim USB connector
`that is integrated with a circuit-board substrate of a flash
`memory card according to the prior art; and FIG. 2 shows a
`cross-sectional view ofAA-AA in FIG. 1. As shown in FIGS.
`1 and 2, the miniaturized USB Pen Driver includes a metallic
`conductive housing 11 having a plurality of orientated inden-
`tation 111, and a print circuit board assembly (PCBA) 12 for
`providing storing memory. Furthermore, the thickness of the
`print circuit board assembly (PCBA) 12 is usually insufli-
`cient,
`thereby making data reading and storing diflicult.
`Therefore, in order to overcome this drawback, the height
`needs to be increased with the aid of another object.
`Consequently,
`the miniaturized USB Pen Driver also
`includes a flake spacer 13 disposed between the metallic
`conductive housing 11 and the PCBA 12 for fitting the PCBA
`12 in the metallic conductive housing 11 tightly, wherein the
`flake spacer 13 could be made from a metallic slice or a plastic
`(Mylar) slice. The flake spacer 13 is used to fill up the space
`between the metallic conductive housing and the PCBA 12.
`However, in practice, the flake spacer 13 is not easy to be
`fabricated into the space between the metallic conductive
`housing 11 and the PCBA 12. Therefore, the USB Pen Driver
`of the prior art could not be miniaturized effectively.
`FIG. 3 shows an assembly of USB memory apparatus
`according to the prior art, and FIG. 4 shows a cross-sectional
`view ofA-A in FIG. 3. As shown in FIGS. 3 and 4, the USB
`memory apparatus includes a metallic conductive housing 31

`
`having a plurality of orientated indentation 311, and a print
`circuit board assembly (PCBA) 32 for providing storing
`memory. Similarly, the miniaturized USB memory apparatus
`also includes a flake spacer 33 disposed between the metallic
`conductive housing 31 and the PCBA 32 for fitting the PCBA
`32 in the metallic conductive housing 31 tightly. Due to the
`flake spacer 33, the inner space of the metallic conductive
`housing 31 is further decreased. In practice,
`there is no
`enough space for introducing a LED indicator. If a LED
`indicator should be introduced into the USB memory appa-
`ratus, the prior art has to add extra space for containing the
`module of the LED indicator. Therefore, the USB memory
`apparatus of the prior art can not introduce a LED indicator
`without increasing extra space, and can not be miniaturized
`effectively
`Although such multi-application USB memory appara-
`tuses are technically feasible, in practice they are very difli-
`cult to implement, as demonstrated by numerous pioneering
`attempts ever since the invention of the miniaturized USB
`memory apparatus itself. It needs to provide a miniaturized
`Universal Serial Bus (USB) memory apparatus, which
`decreases the cost, simplifies the manufacturing process, is
`capable of introducing extra module, such as a LED indicator
`into the USB memory apparatus without increasing entirety
`volume thereof, and can rectify those drawbacks of the prior
`art and solve the above problems.

`
`DETAILED DESCRIPTION OF THE PREFERRED
`EMBODIMENT
`
`The present invention discloses a Universal Serial Bus
`(USB) memory apparatus, and the objects and advantages of
`the present invention will become more readily apparent to
`those ordinarily skilled in the art after reviewing the following
`detailed description. The present invention needs not be lim-
`ited to the following embodiment.
`Please refer to FIG. 5 and FIG. 6. Meanwhile, FIG. 5
`illustrates a preferred embodiment of a USB memory appa-
`ratus according to the present invention, and FIG. 6 illustrates
`a cross-sectional view of A'A'-A'A' in FIG. 5. As shown in
`
`FIGS. 5 and 6, the USB memory apparatus includes a housing
`51 having a plurality of orientated indentations 511 and a
`plurality of concave props 512, wherein the plurality of ori-
`entated indentation 511 facilitates the USB memory appara-
`tus to be connected while the USB memory apparatus is
`inserted into a female USB socket (not shown); and a print
`circuit board assembly (PCBA) 52 disposed in the housing
`51, wherein the PCBA 52 is fixed by means of pressing ofthe
`plurality of concave props 512; and there is a space 53
`between the housing 51 and the PCBA 52.
`In practice, the housing 51 is usually made from a metallic
`conductive material, wherein the plurality of orientated
`indentations 511 and the plurality of concave props 512 can
`be formed simultaneously by means ofpunching on the hous-
`ing 51. In this embodiment, one end of the housing 51 is also
`regarded as a USB male connector, and then the height of the
`insertion end of the housing 51 is the same as a standard
`height of a standard USB male connector. Meanwhile, the
`plurality of orientated indentations 511 are located to engage
`metal springs on the USB socket (not shown), whereby the
`plurality of orientated indentations provide a secure fit into
`the USB socket when inserted. Moreover, the PCBA 52 is
`combined with an end base 54. Usually, the PCBA 52 should
`include several components. Please refer to FIG. 7. It illus-
`trates a PCBA according to the present invention, wherein the

`for maintaining the memory controller 521,
`the storage
`memory 522, and the USB interface 523 together within
`physical dimensions of the USB memory apparatus. Mean-
`while, the storage memory 522 is one of a flash memory and
`an Electrically Erasable Programmable Read Only Memory
`(EEPROM). Certainly, the PCBA 52 could introduce any
`electronic component according to the requirement. Spe-
`cially, the USB memory apparatus of the present invention
`could introduce more components by means of using to the
`space 53 between the housing 51 and the PCBA 52.
`Please refer to FIG. 8 and FIG. 9. Meanwhile, FIG. 8
`illustrates another preferred embodiment of a USB memory
`apparatus according to the present invention, and FIG. 9
`illustrates a cross-sectional view ofA'-A' in FIG. 8. As shown
`
`in FIGS. 8 and 9, the USB memory apparatus includes a
`housing 81 having a plurality of orientated indentations 811
`and a plurality of concave props 812, wherein the plurality of

`board assembly (PCBA) 82 disposed in the housing 81,
`wherein the PCBA 82 is fixed by means of pressing of the
`plurality of concave prop 812 (Please refer to FIG. 6, marked
`as 512); and a LED module having a LED indicator 841
`disposed in the housing 81 and a LED module controller 842
`disposed on the PCBA 82, wherein there is a space 83
`between the housing 81 and the PCBA 82 for facilitating the
`LED module to be disposed.
`In practice, the housing 81 could further include an open-
`ing 85 for facilitating the LED indicator 841 to emit light. The
`housing 81 is usually made from a metallic conductive mate-
`rial, wherein the plurality of orientated indentations 811, the
`plurality of concave props 812, and the opening 85 are um-
`tary. Similar to the above descriptions, one end ofthe housing
`81 is also regarded as a USB male connector, and then the
`height of the insertion end of the housing 81 is the same as a
`standard height of a standard USB male connector. Mean-
`while, the plurality of orientated indentations 811 provide a
`secure fit into the USB socket when inserted. Actually, the
`housing 81 could also be regarded as an entire case ofthe USB
`memory apparatus, thereby decreasing the entire volume of
`the USB memory apparatus. Similarly, the PCBA 82, equal to
`FIG. 7, marked 52, could includes a memory controller 521;
`a storage memory 522 in communication with the memory
`controller 521; a USB interface circuit 523 in communication
`with the memory controller 521; and an integrated circuit
`package 524 for maintaining the memory controller 521, the
`storage memory 522, and the USB interface 523 together
`within physical dimensions of the USB memory apparatus,
`wherein the storage memory 522 is a flash memory or an
`Electrically Erasable Programmable Read Only Memory
`(EEPROM). Certainly, the PCBA 82 could introduce any
`electronic component according to the requirement. In this
`embodiment, the USB memory apparatus further introduces a
`LED module without increasing entirety volume thereof. In
`accordance with the aspect of the present invention, the USB
`memory apparatus of the present invention could introduce
`more components by means of using to the space 83 between
`the housing 81 and the PCBA 82.
`In conclusion, the present invention provides a Universal
`Serial Bus (USB) memory apparatus, which decreases the
`cost and increases the yield because the flake spacer is not
`introduced. Moreover, it simplifies the manufacturing pro-
`cess because the PCBA could be propped up by punched
`concave props instead of uncontrollable flake spacer. Addi-
`tionally, the USB memory apparatus of the present invention
`is capable of introducing extra module, such as a LED indi-
`cator into the USB memory apparatus without increasing
`entirety volume thereof by means of using to the space
`between the housing and the PCBA. On the other hand, the
`housing could also be regarded as an entire case of the USB
`memory apparatus directly. Thus, the USB memory appara-
`tus of the present invention can be miniaturized effectively.
`Certainly, the USB memory apparatus of the present inven-
`tion could further include a decorated case covering the hous-
`ing according to the multi-type design. Meanwhile the prior
`art fail to disclose that. Accordingly, the present invention
`possesses many outstanding characteristics,
`effectively
`improves upon the drawbacks associated with the prior art in
`practice and application, produces practical and reliable
`products, bears novelty, and adds to economical utility value.
`Therefore, the present invention exhibits a great industrial
`value.
`While the invention has been described in terms of what is
`
`presently considered to be the most practical and preferred
`embodiments, it is to be understood that the invention needs
