The utility model beneficial technical effects: on automobile in the charging process, because of circuit board is provided with and the interconnective USB female of usb data line, make its direct current through to the direct electrical equipment of circuit board to being recharged, make its vast be engaged in the user who drives industry can be in driving procedure with the DC power supply on the automobile through its USB onboard charger shell to other electrical equipment of the mobile phone that is recharged or its.Avoid single interchange of the prior art to transform behind the direct current again the defective that can not on automobile, use the electrical equipment charging that is recharged, bring effect easy to use thereby reach to being engaged in the user who drives industry.

For the purpose of this utility model, structural feature and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:

[description of drawings]

Fig. 1 is a kind of USB onboard charger of the utility model three-dimensional exploded view;

Fig. 2 is the schematic diagram for the A---A among Fig. 1.

[embodiment]

See also Figure 1 and Figure 2, illustrate that below in conjunction with first kind of embodiment the utility model adopts a kind of USB onboard charger, it comprises charging shell 1, place circuit board 2, the electricity of charging shell 1 inside be connected to spring 3 on the circuit board 2, be welded in spring 3 other ends the conduction contact 4 that contact with extraneous DC power supply, be installed on spring leaf 5 on the shell 1 that charges, be arranged on the circuit board 2 with the interconnective USB female 7 of usb data line (figure does not draw).On circuit board 2 and both sides that be positioned at USB female 7 are respectively arranged with LED lamp 8.

Described charging shell 1 is ampuliform, its ampuliform is combined by two and half bottles, be provided with the accepting groove 11 that is used to accommodate USB female 7 in the bottom of ampuliform, be respectively arranged with the LED accepting groove 12 that is used to accommodate LED lamp 8 in the both sides of this accepting groove 11, on the side walls of bottleneck, be respectively arranged with contact accepting groove 13, both sides in the inside of this sidewall are respectively arranged with interior plate 14, outer panel 15, form an accommodation space between interior plate 14 and the outer panel 15, formation one is used to accommodate the groove 16 of conduction contact 4 between two interior plates 14.

Described conduction contact 4 is to constitute by the contact cap body 41 that the one end is set and from the cylinder 32 that is used for contact spring 3 that internally extends of contact cap body 31.

Be respectively arranged with spring leaf 5 in the bottleneck both sides.Described spring leaf 5 is to extend outward a curved portions 52 by the end from plate body 51, and this curved portions 52 places the outside of contact accepting groove 13; Tail end in this curved portions 52 forms a kink 53, these kink 53 main contact accepting grooves 13 inside.
