ABSTRACT:
FIELD OF THE INVENTION
The present invention generally relates to a power adapter for connection between a wall outlet and an electrical device, such as a mobile phone and a notebook computer. More particularly, the present invention relates to a power adapter having a cable storage device for storage of a cable thereof.
BACKGROUND OF THE INVENTION
A portable electrical device is often powered by an internal power source, such as a battery set. The internal power source which is usually a rechargeable battery set requires recharging. Thus, a power adapter is used to connect the portable electrical device to an electrical main, such as a wall outlet, for recharging the internal power source or directly powering the portable electrical device.
FIG. 4
of the attached drawings shows a conventional power adapter. The power adapter comprises a body
100
on which an input plug
200
is formed for connection with a wall outlet (not shown). A cable or cord
300
having a first end electrically connected to the input plug
200
extends from the body
100
with a remote second end forms an output plug
400
for connection with a portable electrical device. A disadvantage of the conventional power adapter is that the cable
300
is completely located outside the body
100
. This may cause problem to a user of the portable electrical device. The cable is often tied together by a rope or a rubber band. It is inconvenient to the user.
Thus, it is desired to have a power adapter having a cable storage device for overcoming the above problems.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a power adapter having a cable storage device for advantageously storing an extension cable therein, the cable being readily extended for connection with an electrical device.
Another object of the present invention is to provide a power adapter with an extension cable stored inside a body thereof, the cable being arbitrarily extendible for ready use.
In accordance with the present invention, there is provided a power adapter comprising a body having an upper portion on which a first plug is formed for connection with a wall outlet and a lower portion defining a recess with an axle formed therein for rotatably supporting a reel. A lid is attached to the body for covering the recess. The reel comprises a first disk and a second disk mounted together with a coil spring received therebetween. The coil spring biases the reel in a winding direction for winding a cable thereon. The cable has a first end extending through a central bore of the axle and electrically connected to the first plug and a second end extending beyond the body through an opening defined in the body. A second plug is formed on the second end for connection with an electrical device. The cable may be extended out of the body by being pulled in an unwinding direction against the coil spring. A locking slide is mounted on the body and movable between a closed position and an open position. The locking slide forms a pawl engageable with the cable when the slide is moved to the closed position thereby securing the cable in position.
