The utility model content:

The purpose of this utility model is to provide a kind of USB charger that helps improving versatility scope and flexibility at the deficiencies in the prior art.

For achieving the above object, the utility model adopts following technical scheme:

The USB charger, comprise housing, be positioned at the connected external power source on the housing pin, be positioned at the circuit board of enclosure interior, the input of circuit board is electrically connected pin, described housing is provided with the USB maternal interface that can be connected with the data wire that has USB plug, and the output of circuit board is electrically connected the USB maternal interface.

Offer the open slot with the corresponding coupling of USB maternal interface on the described housing, open slot is communicated with the inner chamber of housing, and the USB maternal interface is fastened in the open slot.

Described housing is combined by left shell that is positioned at the left and right sides and right shell body, and open slot is opened in the joint of left shell and right shell body.

Described housing is provided with LED light, and LED light is electrically connected with circuit board.

Offer loophole on the described housing, LED light is plugged in the loophole.

The left and right sides of described housing is respectively equipped with many stripe.

Described many stripe are parallel horizontal straight line line.

Described striped is a burr.

The utility model beneficial effect is: the utility model comprises housing, be positioned at the pin of the connected external power source on the housing, be positioned at the circuit board of enclosure interior, the input of circuit board is electrically connected pin, housing is provided with the USB maternal interface that can be connected with the data wire that has USB plug, the output of circuit board is electrically connected the USB maternal interface, the data wire that during use electronic products such as mobile phone is passed through first wife's band USB plug connects the USB maternal interface, utilize after the circuit board step-down by USB maternal interface and data wire battery and charge electronic products such as mobile phones, output interface is the Universal USB maternal interface, the charging inlet of electronic products such as the suitable different type mobile phone of energy, the versatility wide ranges, the flexibility height, easy to use.

In addition, the left and right sides of housing is respectively equipped with many stripe, has increased the frictional force between hand and the housing, in the feel preferably that has of plug charger, is not easy sliding hand, and is safe and reliable.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a decomposing schematic representation of the present utility model.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described, see Fig. 1,2, a kind of USB charger that the utility model provides comprises housing 1, be positioned at the pin 2 of the connected external power source on the housing 1, be positioned at the circuit board 3 of housing 1 inside, the input of circuit board 3 is electrically connected pin 2, described housing 1 is provided with the USB maternal interface 4 that can be connected with the data wire that has USB plug, and the output of circuit board 3 is electrically connected USB maternal interface 4.

Further, offer the open slot 13 with USB maternal interface 4 corresponding couplings on the housing 1, open slot 13 is communicated with the inner chamber of housing 1, and USB maternal interface 4 is fastened in the open slot 13, and is easy for installation.Housing 1 is linked to connect by left shell 11 that is positioned at the left and right sides and right shell body 12 composite cards and forms, open slot 13 is opened in the joint of left shell 11 and right shell body 12, left shell 11 and right shell body 12 are located separately in the middle of open slot 13, when USB maternal interface 4 is installed, earlier USB maternal interface 4 is placed on the open slot 13 of right shell body 12, then left shell 11 is connected on the right shell body 12, simultaneously USB maternal interface 4 cards is pressed in the open slot 13, easy to assembly.
