ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a portable storage device with universal serial bus (USB), and more particularly to a portable storage device having a connector retractable into a case thereof.
BACKGROUND OF THE INVENTION
FIG. 1
is an exploded perspective view of a conventional portable storage device, which includes a case
5
, a connector
6
, and a cover
51
detachably connected to the case
5
to cover the connector
6
. Wherein, the connector
6
is a USB connector.
The case
5
of the above-described conventional portable storage device is internally provided with circuits for storing and transmitting computer data, and is electrically connected to the connector
6
, such that when the cover
51
is removed from the case
5
to expose the connector
6
, the connector
6
may be directly plugged into a USB connector provided on a computer to function like an externally connected hard disk drive to transmit or store data. When the connector
6
is unplugged, the portable storage device can be carried by a user to any other place or be connected to another computer. Therefore, the portable storage device is highly mobile and convenient for use.
The connector
6
of the above-described conventional portable storage device is integrally connected to an end of the case
5
, and is protected by the cover
51
against uselessness resulted from collision, damage, distortion or deformation of the connector
6
. The cover
51
is completely separated from the case
5
once it is removed therefrom. In the event a user carelessly lost the separated cover
51
, the connector
6
is no longer suitably protected and tends to become damaged, failed, and unusable.
It is therefore tried by the inventor to develop a portable storage device with a retractable connector to eliminate the drawbacks existed in the conventional portable storage device.
SUMMARY OF THE INVENTION
A primary of the present invention is to provide a portable storage device with universal serial bus (USB), so that a USB connector thereof may be freely retracted into a case to avoid undesired damage of the connector, and a user needs not to worry about any lost cover at all.
To achieve the above and other objects, the portable storage device with USB of the present invention mainly includes a case defining a hollow chamber having a front opening, a main body consisting of a circuit board and a connector located in front of the circuit board and being movably positioned in the hollow chamber of the case, and a push member located above and connected to the main body by way of interference fit to expose from a recess formed at a rear top of the case. When the push member is pushed forward and rearward, the connector of the main body is caused to project from or retract into a front end of the case.
