Abstract

The utility model provides a USB charger with a plurality of USB interfaces, which comprises a flat casing, an upward frustum-shaped casing is formed at the middle part of the top plate of the flat casing; an insertion hole capable of connecting a power supply is formed on the top plate of the frustum-shaped casing; the plurality of USB interfaces are arranged on the lateral side of the flat casing; the frustum-shaped casing and the flat casing form an accommodating space for placing a charging circuit; and the charging circuit is used for converting AC into low voltage DC to power the USB interfaces. The USB charger is provided with the plurality of USB interfaces, and can power a plurality of electric appliances via the same USB interface data cable; and in addition, the charging circuit is placed in the accommodating space formed by the frustum-shaped and the flat casing, so that the integral structure of the USB charger is compact.

Description

A kind of USB charger
Technical field
The utility model relates to a kind of USB charger.
Background technology
In sphere of life, common electrical equipment such as mobile phone, camera are widely used.Basically all attach the USB interface data wire when buying these electrical equipment, the USB interface data wire also has the effect that is connected with charger with to the electrical equipment charging except the data communication purpose.Charger only has a USB interface, and volume is bigger, when a plurality of electrical equipment need charge simultaneously, because the jack of supply socket is limited, can not satisfy the demands.
Summary of the invention
The technical problem that the utility model will solve provides a kind of USB charger that a plurality of USB interfaces can be provided.
In order to solve the problems of the technologies described above, the technical scheme of the utility model is:
A kind of USB charger; Comprise shallow shell; Shallow shell top board middle part upwards forms frustum shell, and the jack that can connect power supply is set on the frustum shell top board, and the shallow shell side is provided with some USB interfaces; Frustum shell and shallow shell have surrounded the accommodation space of ccontaining charging circuit jointly, and charging circuit converts alternating current into low-voltage DC and supplies with USB interface.
The utlity model has a plurality of USB interfaces, can supply a plurality of electrical equipment to need simultaneously through the charging of USB interface data wire.Charging circuit is positioned in the accommodation space that frustum shell and shallow shell surround jointly, makes the utility model compact overall structure.
The technical problem that the utility model will solve is that a kind of USB charger that a plurality of USB interfaces can be provided is provided again.
In order to solve the problems of the technologies described above, the technical scheme of the utility model is:
A kind of USB charger; Comprise a USB charger and the 2nd USB charger, a USB charger and the 2nd USB charger include shallow shell, and shallow shell top board middle part upwards forms frustum shell; The jack that can connect power supply is set on the frustum shell top board; The shallow shell side is provided with some USB interfaces, and frustum shell and shallow shell have surrounded the accommodation space of ccontaining charging circuit jointly, and charging circuit converts alternating current into low-voltage DC and supplies with USB interface; The shallow shell side of the one USB charger and the 2nd USB charger also is provided with and can a USB charger and the 2nd USB charger be combined into whole connecting portion.
Through a USB charger and the combination of the 2nd USB charger are used, further increased the quantity of USB interface, enlarged the electrical equipment quantity of charging simultaneously.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation:
Fig. 1 is the structural representation of USB charger.
Fig. 2 is the structural representation of a USB charger among Fig. 1.
Fig. 3 is the end view of Fig. 2.
Fig. 4 is the structural representation of the 2nd USB charger among Fig. 1.
Among the figure: 1 shallow shell, 2 jacks, 3 connecting portions, 4 frustum shells, 5 USB interfaces, 6 connecting portions, 7 the 2nd USB chargers, 8 the one USB chargers.
Embodiment
Explanation for ease, an existing USB charger 8 and the 2nd USB charger 7 at first explained is combined into the structure of whole USB charger.
Shown in Fig. 1-4; A kind of USB charger comprises a USB charger 8 and the 2nd USB charger 7; The one USB charger and the 2nd USB charger include shallow shell 1; Shallow shell top board middle part upwards forms frustum shell 4, and the jack 2 that can connect power supply is set on the frustum shell top board, and the shallow shell side is provided with some USB interfaces 5; Frustum shell and shallow shell have surrounded the accommodation space of ccontaining charging circuit jointly, and charging circuit converts alternating current into low-voltage DC and supplies with USB interface; The shallow shell side of the one USB charger and the 2nd USB charger also is provided with and can a USB charger and the 2nd USB charger be combined into whole connecting portion (3 and 6).
Above-mentioned this assembling mainly is for the USB interface that is had when a USB charger (a USB charger or the 2nd USB charger) when not enough, carries out USB interface and expands, to satisfy the demand.
The structure of the another kind of USB charger of the utility model protection is following:
Shown in Fig. 2-3; A kind of USB charger shallow shell top board middle part upwards forms frustum shell; The jack that can connect power supply is set on the frustum shell top board; The shallow shell side is provided with some USB interfaces, and frustum shell and shallow shell have surrounded the accommodation space of ccontaining charging circuit jointly, and charging circuit converts alternating current into low-voltage DC and supplies with USB interface.This USB charger has a plurality of USB interfaces, can supply a plurality of electrical equipment to need simultaneously through the charging of USB interface data wire.Charging circuit is positioned in the accommodation space that frustum shell and shallow shell surround jointly, makes the utility model compact overall structure.
