8 is a reference view showing the operation of the third embodiment of the mobile phone charger according to the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 and 3 illustrate a mobile phone charger according to the present invention. The mobile phone charger includes a main body 10 having a plug 20 coupled to an outlet of a commercial power source, And a charging cable 40 having one end connected to the charging circuit 30 and the other end having a charging tab 50 detachably coupled to the charging terminal of the mobile phone, Is the same as the conventional one.

At this time, the main body 10 is formed of a synthetic resin material, and a through hole 13 through which the charging cable 40 passes is formed at one side.

The plugs 20 are formed as a pair of left and right sides and are spaced apart from each other in a mutually corresponding manner to correspond to the coupling holes formed in the socket-outlet.

According to the present invention, there are provided a take-up reel 60 rotatably coupled to the inside of the main body 10 and wound around the charging cable 40 on a circumferential surface thereof, An elastic member 70 for rotating the take-up reel 60 so that the cable 40 is wound on the circumferential surface of the take-up reel 60, fixing means 70 for fixing the take- (80).

For this, a rotating shaft 11 is provided in the main body 10, and the take-up reel 60 is rotatably coupled to the rotating shaft 11. [

The elastic member 70 is fixed to the take-up reel 60 at one end and is coupled to the rotation shaft 11 to use a torsion spring or a spring to elastically rotate the take-up reel 60.

The fixing means 80 includes a ratchet gear 81 formed on a circumferential surface of the take-up reel 60 and an intermediate portion pivotally coupled to the main body 10, A ratchet member 82 having a latching protrusion 82a formed at one end of the ratchet member 82 and a pushing portion 82b extending outwardly at the other end of the ratchet member 82, And a spring 83 elastically pressing the latching jaw 82a to be engaged with the ratchet gear 81. [

At this time, in a state where the ratchet gear 81 and the latching jaws 82a of the ratchet member 82 are engaged with each other, the take-up reel 60 is rotated in the direction in which the charging cable 40 is unwound, Is fixed so as not to rotate in the winding direction.

2, when the user pulls the charging tab 50 exposed to the outside of the main body 10, the charging reel 60 is rotated, And at this time, the elastic member 70 is compressed.

Conversely, when the user presses the pressing portion 82b of the ratchet member 82, the engagement between the ratchet gear 81 and the engaging protrusion 82a is released, and the elastic member 70 The charging cable 40 is wound while the winding reel 60 is rotated.

When the user pulls the power cable 40, the power cable 40 wound around the take-up reel 60 is pulled out of the main body 10 So that the charging tab 50 provided at the end of the power cable 40 can be connected to the portable terminal for charging.

When the charging is completed and the mobile phone charger is not used, the power cable 40 is wound around the take-up reel 60 and stored in the main body 10 when the user presses the pushing portion 82b.

Therefore, it is easy to carry and store.

In the present embodiment, the fixing means 80 includes a ratchet gear 81 formed on the circumferential surface of the take-up reel 60, a middle portion rotatably coupled to the main body 10, A ratchet member 82 having a latching protrusion 82a selectively engaged with the ratchet member 82 and a pressing portion 82b extending outwardly from the body 10 at the other end thereof; And a spring 83 elastically urging the engaging protrusion 82a of the member 82 to be engaged with the ratchet gear 81. However, the structure of the fixing means 80 may be variously changed .

4 and 5 illustrate another embodiment according to the present invention. At one side of the main body 10, an engaging groove 12 is formed for engaging and fixing the charging tab 50.

The engaging groove 12 is formed concavely in a side surface of the main body 10 in the same shape as the charging tab 50.

5, when the portable charger is not used, the charging tab 50 is inserted into the engaging groove 12 (see FIG. 5) , The charging tab 50 can be fixed so as not to move.

Therefore, when the portable charger is stored in a bag or the like together with other objects, the charging tab 50 is pulled by other objects, thereby preventing the charging cable 40 from being pulled out of the main body 10 to be tangled or damaged There are advantages to be able to.

5 to 8 illustrate a third embodiment of the present invention in which the through holes 13 are formed to be positioned between the plugs 20 on the circumferential surface of the main body 10, (50) is positioned between the plugs (20) when the take-up reel (40) is wound on the take-up reel (60).

In this case, the lateral width of the filling tab 50 is made wider than the interval between the adjacent surfaces of the plug 20, and on both sides of the filling tab 50, Grooves 51 are formed.

Therefore, after the charging cable 40 is wound on the take-up reel 60, the engaging groove 51 of the charging tab 50 is engaged with the circumferential surface of the plug 20, Can be fixed so as not to move.

When the mobile phone charger thus configured is not in use, the charging tab 50 can be fixed between the plugs 20 as shown in FIGS. 6 and 7, And is fixed by the plug 20 so as not to move.

This makes it possible to fix the filling tab 50 more effectively and to make the size of the main body 10 more compact than the second embodiment described above in which the filling tab 50 is fitted and fixed in the coupling groove 51, There is an advantage that it can be configured.
