Universal serial bus (USB) memory device

A USB memory plug, comprising:

• a print circuit board assembly (PCBA);
• and
• a housing having a plurality of concave props, wherein said PCBA is disposed in said housing;
• said plurality of concave props protrude inward to fix said PCBA, and a space is formed between said housing and said PCBA.

A USB memory plug, comprising:

• a housing having a plurality of orientated indentations and a plurality of concave props, wherein said plurality of orientated indentation facilitates said USB memory plug to be connected while said USB memory plug is inserted into a female USB socket;
• a print circuit board assembly (PCBA) disposed in said housing, wherein said PCBA is fixed by means of pressing of said plurality of concave props;
• and
• a LED module having a LED indicator disposed in said housing and a LED module controller disposed on said PCBA, wherein a space is formed between said housing and said PCBA for disposing said LED module.

A USB memory device, comprising:

• a print circuit board assembly (PCBA);
• and
• a housing having a plurality of concave props and a plurality of orientated indentations, said plurality of concave props and said plurality of orientated indentations are located on an insertion end of said housing, wherein said PCBA is disposed in said housing, said plurality of concave props are respectively disposed within said plurality of orientated indentations on a side of said housing and said plurality of concave props coincide with a portion of said plurality of orientated indentations on said insertion end of said housing,
• wherein each of the orientated indentations keeps a distance from a front opening of said housing, and said concave props are isolated from said front opening with the distance,
• said plurality of orientation indentations are not penetrated through said housing, said plurality of concave props protrude inward to fix said PCBA, and said plurality of concave props support said PCBA apart from said housing to form a space between said housing and said PCBA,
• wherein said front opening of said housing has a longitudinal axis perpendicular to said insertion end, said plurality of orientation indentations and said plurality of concave props are symmetrically disposed along said longitudinal axis and disposed corresponding to a plurality of engaging positions configured to engage with a plurality of springs of a female USB socket.
