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 orientated indentation 511 facilitates the USB memory apparatus 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 of the plurality of concave props 512; and there is a space 53 between the housing 51 and the PCBA 52.

(12) 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 of punching on the housing 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 illustrates a PCBA according to the present invention, wherein the PCBA 52 further 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. Meanwhile, 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. Specially, 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.

(13) 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 of A-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 orientated indentation 811 (which is located to engage metal springs on the female USB socket) facilitates the USB memory apparatus to be connected while the USB memory apparatus is inserted into a female USB socket; a print circuit 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.

(14) In practice, the housing 81 could further include an opening 85 for facilitating the LED indicator 841 to emit light. The housing 81 is usually made from a metallic conductive material, wherein the plurality of orientated indentations 811, the plurality of concave props 812, and the opening 85 are unitary. Similar to the above descriptions, one end of the 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. Meanwhile, 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 of the 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.

(15) 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 process because the PCBA could be propped up by punched concave props instead of uncontrollable flake spacer. Additionally, the USB memory apparatus of the present invention is capable of introducing extra module, such as a LED indicator 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 apparatus of the present invention can be miniaturized effectively. Certainly, the USB memory apparatus of the present invention could further include a decorated case covering the housing 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.
