Abstract

The power adapter includes a body, the 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 having an axis formed on the recess for rotatably supporting the reel. A lid is attached to the body to cover the recess. The reel includes a first disk and a second disk installed with a coil spring received between the first disk and the second disk. The coil spring biases the reel in a winding direction to wind the cable on the reel. The cable has a first end extending through the central hole of the shaft 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 at the second end for connection with the electrical device. The cable may extend out of the body by pulling in the unwinding direction with respect to the coil spring. A locking slide can be installed on the body to move between the closed position and the open position. The locking slide forms a detent that can engage the cable when the slide is moved to the closed position, whereby the cable can be placed in a predetermined position.

Description

Power adapter with cable receptacle {POWER ADAPTER WITH CABLE STORAGE DEVICE}

The present invention generally relates to a power adapter for connection between an electrical device such as a mobile phone and a notebook computer and a wall outlet. More specifically, the present invention relates to a power adapter having a cable receiving device for receiving a cable of the power adapter.

Portable electrical devices are often powered by internal power sources such as battery sets. Internal power sources, usually rechargeable battery sets, require recharging. Thus, a power adapter is used to connect the portable electrical device to an electrical mains, such as a wall outlet, to recharge the internal power source or directly supply power to the portable electrical device.

4 of the accompanying drawings shows a conventional power adapter. The power adapter includes 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 to form an output plug 400 for connection with a portable electrical device. Is connected to two ends. The inconvenience of the conventional power adapter is that the cables 300 are all located outside of the body 100. This can cause problems for users of portable electrical devices. Cables are often tied together by ropes or rubber bands. This is inconvenient for the user.

Therefore, it is desirable to have a power adapter having a cable receiving device that can overcome the above problems.

It is therefore an object of the present invention to provide a power adapter having a cable receiving device for accommodating an extension cable in a power adapter that can be easily extended for connection with an electrical device.

Another object of the present invention is to provide a power adapter having an extension cable that is housed inside the body of the power adapter and can be arbitrarily extended for quick use.

According to the present invention, there is included 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 having an axis formed therein for supporting the reel to rotate. A lid is attached to the body to cover the recess. The reel includes a first disc and a second disc, with a coil spring received therebetween mounted with the first disc and the second disc. The coil spring biases the reel in the winding direction to wind the cable onto the reel. The cable has a first end extending through the central hole of the shaft and electrically connected to the first plug, and a second end extending beyond the body through the opening defined in the body. A second plug is formed at the second end for connection with the electrical device. The cable can be extended out of the body by pulling in the unwinding direction with respect to the coil spring. A locking slide can be installed on the body to move between the closed position and the open position. The locking slide forms a detent that can engage the cable when the slide is moved to the closed position so that the cable is in the desired position.

The present invention will become clear as those skilled in the art understand the following detailed description of the preferred embodiments with reference to the accompanying drawings.

1 and 2, in which a power adapter constructed in accordance with the present invention is shown, in particular, the power adapter has an upper portion in which a first plug 13 is formed for connection with an exemplary wall outlet (not shown); And a body 1 having a lower portion defining an inner space 11 covered by a removable lid 7. The lid 7 is attached to the body 1 by any known means, such as a bolt 8 that can engage an inner threaded hole 14 formed in the inner space 11.

The reel assembly is rotatably supported in the inner space 11 of the body 1 with the cable 300 wound around the reel assembly. The reel assemblies are first discs installed coaxially with each other to define a space between the first disc 5 and the second disc 3 to receive a coil spring 4 for biasing the reel assembly in the winding direction. (5) and the second disk (3). The shaft 2 is installed inside the inner space 11 and extends through the center hole defined in the disks 5 and 3 to rotatably support the reel assembly.

The inner end of the cable 300 extends through a central hole (not shown) of the shaft 2 to electrically connect to the first plug 13. The outer end of the cable 300 extends beyond the body 1 such that the cable portion 300 is wound between the disks 5 and 3 so that when the user pulls the outer end of the cable 300, the reel assembly is coiled. The cable extends as shown by the imaginary line in FIG. 1 by rotating in the unwinding direction with respect to the spring 4. A second plug 400 is installed at the outer end of the cable 300 for connection with the electrical device, so that power is supplied from the wall outlet to the electrical device through the cable 300.

When the cable 300 is unwound, the coil spring 4 which exerts an eccentric force on the reel assembly in the winding direction causes the reel assembly to rotate in the winding direction and pulls the cable 300 into the inner space 11 of the body 1. Put it in.

Referring also to FIG. 3, a race 12 is defined in the body 1 to accommodate the slide 6 in the race 12. In the race 12 the slide 6 can move between a closed position and an open position. A protrusion 61 is formed in the slide 6 to manually move the slide 6 in the race 12. An opening (unsigned) is defined in the body, through which the cable 300 extends. An opening is positioned next to the race 12 such that the detent 62 formed on the slide 6 engages when the slide 6 is moved to the closed position to secure the cable 300, the slide 6 Cable 300 is released when is moved to the open position.

In this regard, the present invention allows the user to arbitrarily extend the cable 300 by pulling the cable 300 against the coil spring, and fix the cable 300 to a predetermined position by using the slide 6.

Although the present invention has been described with respect to the preferred embodiments, it will be understood that various modifications, modifications and alternative means may be practiced without departing from the scope of the present invention, the invention being defined by the appended claims.

As described above, according to the present invention, by providing a power adapter having a cable accommodating device for accommodating an extension cable in the power adapter, which can be easily extended for connection with an electrical device, the user's convenience can be achieved. have.
