With the integrated battery charger of USB socket
Technical field
The present invention relates to a kind of charger construction of battery, particularly the integrated battery charger with USB socket.
Background technology
Rechargeable battery, compared with traditional disposable battery, has the advantages such as easy to use, cost-saving, environmental protection, and therefore its scope of application will be more and more extensive.For can be in the time that electric weight be not enough timely makeup energy, rechargeable battery need to coordinate charger to use.
Current battery charger is generally to exchange input, and the alternating voltage of inputting is converted into after by voltage transitions and is applicable to battery powered direct voltage.Owing to will carrying out AC-DC conversion, therefore these battery chargers generally all need to configure the devices such as transformer, and this makes overall battery charger volume larger, and structure is compact not, and also has in the use certain potential safety hazard.
Summary of the invention
For addressing the above problem, the invention provides that a kind of volume is little, compact conformation and use the integral charger with USB socket of safety.
The present invention for the technical scheme that its problem of solution adopts is:
With the integrated battery charger of USB socket, comprise shell and be arranged on shell for placing the battery chamber of rechargeable battery, the two ends of battery chamber are provided with the sheet metal being connected with battery electrode, one charging circuit board is installed in shell, sheet metal and charging circuit board electrical connection, it is characterized in that on described shell, being fixedly installed one for directly introducing the USB socket of external voltage, described USB socket and charging circuit board electrical connection.
Preferably, described sheet metal comprises the first sheet metal for being connected with battery one electrode and the second sheet metal and the 3rd sheet metal for being connected with another electrode of battery, and the 3rd sheet metal is arranged on the position between the first sheet metal and the second sheet metal.
The distance of the first sheet metal and the second sheet metal and AA battery length match, and the distance of the first sheet metal and the 3rd sheet metal and AAA battery length match.
Battery chamber comprises and being arranged between the second sheet metal and the first sheet metal for supporting the horizontal mounting groove of AA battery, laterally in mounting groove, is provided with the oblique mounting groove for supporting AAA battery, and described the 3rd sheet metal is arranged at the bottom of oblique mounting groove.
The bottom of described shell is a planar base surface, and described charging circuit board is fixed on planar base surface top to be parallel to the mode of planar base surface.

Embodiment
See figures.1.and.2, integrated battery charger with USB socket of the present invention, comprise shell 1 and be arranged on shell 1 for placing the battery chamber 2 of rechargeable battery, the two ends of battery chamber 2 are provided with the sheet metal 3 being connected with battery electrode, usually, this sheet metal generally adopts the form of contact in anode junction, generally adopt the form of shell fragment in battery cathode junction.One charging circuit board 4 is installed in shell 1, and sheet metal 3 is electrically connected with charging circuit board 4, is fixedly installed one for introducing the USB socket 5 of external voltage on described shell 1, and described USB socket 5 is electrically connected with charging circuit board 4.In the time that rechargeable battery charges, first battery is put into battery chamber 2, the positive and negative electrode of battery is contacted, the work of can charging normally of then switching on sheet metal 3 according to correct direction.
The battery variety using is at present various, in order to make the present invention can meet the charging needs of more battery products, as preferred embodiment, sheet metal 3 comprises the first sheet metal 31 for being connected with battery one electrode and is arranged on the position between the first sheet metal 31 and the second sheet metal 32 for the second sheet metal 32 and the 3rd sheet metal 33, the three sheet metals 33 that are connected with another electrode of battery.By can make this charger can meet the charging needs of two kinds of different rechargeable batteries to the first sheet metal 31 and arranging of the distance of the second sheet metal 32 and the distance to the first sheet metal 31 and the 3rd sheet metal 33 simultaneously.Consider that conventional battery is generally AA battery and AAA battery at present, therefore further preferably the distance of the first sheet metal 31 and the second sheet metal 32 and AA battery length match, distance is left and right, 50.5mm ± 2.0, the distance of the first sheet metal 31 and the 3rd sheet metal 33 and AAA battery length match, and distance is left and right, 44.5mm ± 2.0.The charged state of AA battery and AAA battery respectively as shown in Figure 4 and Figure 5.In addition, in order to ensure charger construction compactness, being convenient to battery places, battery chamber 2 comprises and is arranged between the second sheet metal 32 and the first sheet metal 31 laterally battery mounting groove 21, laterally in battery mounting groove 21, be provided with oblique battery mounting groove 22, described the 3rd sheet metal 33 is arranged at the bottom of oblique battery mounting groove 22.
