Abstract
The utility model relates to a portable inverter power source, which comprises a body and a connecting line. One end of the connecting line is of a combined lighter structure. A combined lighter includes a lighter body, an aviation male plug butted with the lighter body, and an aviation female socket disposed at the other end of the lighter body, wherein a bayonet preventing the female socket from releasing is arranged on the aviation male plug. The body adopts a rectangular plastic casing. The portable inverter power source has the advantages of small volume, light weight, convenient carrying, wide application range available for autos, airplanes and the like due to the fact that a direct current input portion of the connecting line adopts the combined lighter structure, and capability of effectively reducing surface temperature of products by adopting the plastic casing.
Description
Technical field
The utility model relates to a kind of inverter, specifically is meant a kind of small portable inverter of using on automobile or the aircraft of being suitable for.

In the prior art, the inverter product casing generally adopts aluminium section bar, and small product size is big, Heavy Weight, and also most of product adopts shell as radiator, and aluminium is Heat Conduction Material, and skin temperature is higher during work, and hand can not touch product surface, is not suitable for carrying.Inverter direct current importation is adopted the hair style connection-pegs that light a cigarette more now in addition, and this plug only is applicable to that generally automobile uses, and is restricted the product scope of application.
The utility model content
The small-sized inverter that provides a kind of scope of application wide, easy to carry is provided the purpose of this utility model.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of portable inverter power supply is provided, comprise power supply body and connecting line, the power supply body is provided with the direct current input interface, exchanges output interface and USB output interface, and the described connecting line other end that is used with the direct current input interface adopts combined cigar lighter structure.
Described combined cigar lighter comprises cigar lighter main body and the aviation plug male seat of docking with it; Described aviation plug female seat is arranged at an end of cigar lighter main body, is structure as a whole with the cigar lighter main body.
Described aviation plug male seat is provided with and prevents the bayonet socket that female seat is deviate from when being used for the socket of aviation plug female seat.
Described USB output interface is a standard USB interface; Described USB output interface first pin connects+5V power end, the 4th pin ground connection, be connected with resistance between second and third pin of USB output interface, and crus secunda also connects+the 5V power end by a resistance simultaneously, and tripod is also by a grounding through resistance.
With respect to prior art, the utility model beneficial effect is:
(1) the combined cigar lighter structure that adopts of its direct current importation, the scope of application is extensive, on the automobile, aircraft is first-class all can use;
(2) the utility model adopts the plastic cement material shell simultaneously, effectively reduces product surface temperature and weight;
(3) small product size is little, in light weight, is easy to carry.
Description of drawings
Fig. 1 is that the utility model embodiment power supply body construction is formed schematic diagram;
Fig. 2 is the combined cigar lighter structure front schematic view of the utility model embodiment;
Fig. 3 is the utility model embodiment USB circuit diagram.
Embodiment
For ease of it will be appreciated by those skilled in the art that the utility model is described in further detail below in conjunction with drawings and Examples.
The utility model comprises power supply body 1 and connecting line 2.With reference to Fig. 1 is the composition structure chart of described power supply body 1, and the loam cake of power supply body 1 is opened among the figure, can see internal structure.Power supply body 1 is provided with direct current input interface 11, exchanges output interface 12 and USB output interface 13, and inside is provided with direct current～ac converter circuit.As figure, power supply body 1 shell is cuboid, and material is a plastic cement.
As Fig. 2, connecting line 2 other ends that are used with direct current input interface 11 adopt combined cigar lighter structure.Combined cigar lighter structure comprises cigar lighter main body 21 and docks the aviation plug male seat 22 of use with it, with the aviation plug female seat 23 that is arranged at cigar lighter main body 21 1 ends, aviation plug male seat 22 is provided with and prevents the telescopic bayonet socket 222 that female seat 23 is deviate from when being used for female seat 23 sockets.
When the utility model was used on the automobile, aviation plug male seat 22 was pegged graft with aviation plug female seat 23, and bayonet socket 222 blocks both, wholely formed a cigarette lighter plug, pegged graft with cigar lighter on the automobile, and automobile storage battery 12V direct current is introduced.This power supply is exported to other power consumption equipment use after converting alternating current to by inverter circuit.And the utility model separates aviation plug male seat 22 when being used on the aircraft with aviation plug female seat 23; Aviation plug male seat 22 directly is plugged on the power supply female seat on the aircraft, direct current is converted to alternating current output uses for miscellaneous equipment.
Among the embodiment, the USB output interface 13 that is provided with on the power supply body 1 adopts standard USB interface, and this kind USB interface can be used for user's plurality of devices, for example gives cell-phone charging.Described USB output interface 13 is a standard USB interface, and is similar with the existing interface circuit.USB output interface (J1) 1 pin connects+5V power end, 4 pin ground connection, characteristics are to be connected with resistance R 110 between USB output interface (J1) 2,3 pin, simultaneously 2 pin also by resistance R 111 connect+5V power end 3 pin are also by resistance R 109 ground connection.Through electric resistance partial pressure, obtain the voltage of a 2.75V and 2.06V on 2,3 pin of interface J1 respectively, make it be suitable for the power demands of some special installations.
