Description

A USB charger

technical field

The utility model relates to a USB charger.

Background technique

In the field of life, common electrical appliances such as mobile phones and cameras are widely used. When these electrical appliances are purchased, USB interface data cables are basically included. In addition to the purpose of data communication, the USB interface data cables also have the function of connecting with a charger to charge the electrical appliances. The charger has only one USB interface, and the volume is relatively large. When multiple electrical appliances need to be charged at the same time, the sockets of the power socket are limited, which cannot meet the demand.

FIG. 2 is a schematic structural diagram of the first USB charger in FIG. 1 . the

FIG. 3 is a side view of FIG. 2 . the

FIG. 4 is a schematic structural diagram of the second USB charger in FIG. 1 . the

In the figure: 1 flat shell, 2 jack, 3 connecting part, 4 frustum-shaped shell, 5 USB interface, 6 connecting part, 7 second USB charger, 8 first USB charger. the

Detailed ways

For the convenience of description, the structure of the USB charger in which the first USB charger 8 and the second USB charger 7 are combined is firstly described. the

As shown in Figures 1-4, a USB charger includes a first USB charger 8 and a second USB charger 7, the first USB charger and the second USB charger both include a flat housing 1, and the flat housing top plate The middle part forms a frustum-shaped casing 4 upwards, and the top plate of the frustum-shaped casing is provided with a jack 2 that can be connected to a power supply. A number of USB interfaces 5 are provided on the side of the flat casing. The frustum-shaped casing and the flat casing together form a storage charging circuit. The accommodating space, the charging circuit converts the alternating current into a low-voltage direct current and supplies it to the USB interface; the sides of the flat housings of the first USB charger and the second USB charger are also provided with the ability to combine the first USB charger and the second USB charger into a Integral connections (3 and 6). the

The above assembly is mainly for expanding the USB interface to meet the needs when the USB interface of a USB charger (the first USB charger or the second USB charger) is not enough. the

The structure of another USB charger protected by the utility model is as follows:

As shown in Figure 2-3, a USB charger flat shell top plate middle part upwards to form a truncated cone-shaped shell, the top plate of the truncated cone-shaped shell is provided with a jack that can be connected to the power supply, and several USB ports are provided on the side of the flat shell. The casing and the flat casing jointly enclose the accommodating space for accommodating the charging circuit, and the charging circuit converts alternating current into low-voltage direct current to supply to the USB interface. The USB charger has a plurality of USB interfaces, and can be used for multiple electric appliances to be charged through the USB interface data lines at the same time. The charging circuit is placed in the accommodating space enclosed by the truncated cone shell and the flat shell, so that the overall structure of the utility model is compact.
