Portable storing device with universal serial bus

摘要

A portable storing device with universal serial bus (USB) includes a housing being provided at a predetermined position with a through hole having an outer mask fitted therein; a housing cap being closed to an open end of the housing; and a storage unit being located in an inner space defined between the housing and the housing cap, and including a storage circuit board, a light emitting diode (LED), and a USB. The LED is enclosed in an inner cover, and the inner cover is fitly seated in the outer mask to fill up the through hole on the housing, so that moisture and dust are prevented from entering into the housing via the through hole while the LED is accurately located in place in the through hole for easy observation thereof.
