Abstract
The utility model relates to a pwer supply charger which is composed of a mains charger epivalve, a bottom shell, a protecting cover, a cross curve, a printed board with elements, a bolt and a charging circuit. The utility model is characterized in that a secondary battery barn is composed of the epivalve, the protective cover and the epivalve bottom board. Two sets of polar boards are arranged in the secondary battery barn. The two sets of polar boards can be shared by the batteries 5#, 7#. The edge part of the bottom shell is provided with a transfer switch which can change polarities and a charge power supply output switch which can realize charge with three speeds of fast, middle and slow. The charging circuit is composed of a reduction voltage rectification circuit, two paralleled 3-speed charging circuit and a polarity adjustable output circuit. The utility model has the advantages of compactness, elegance, wide adaptability and reliable performance.
Description
The utility model relates to a kind of many grades of multi-functional direct currents outputs that both had, have again fast in the mains charger of slow three fast charge functions.
Also can see the mains charger that power supply and charging are incorporated into one in the market, but this common class mains charger is big except volume, collect, carry the inconvenience, main is that its power supply output of this series products has only a polarity and single grade of voltage output, live part also just is applicable to charging at a slow speed, simultaneously with it during to the different model battery charge, additional aids could realize in addition, the mains charger that some small sizes are also arranged on the market certainly, but they are unifunctional mostly.In addition, also have some to adopt the product of capacitor step-down, its deficiency is obvious especially: little, the poor reliability of power output.
The purpose of this utility model: be to provide a kind of and can overcome above-mentioned numerous defective, the small and exquisite exquisiteness of outward appearance, novel and reasonable structure, dependable performance, safe novel power supply charger multiple functional, easy to use.
This mains charger is made up of printed board (7), latch (16) and the charging circuit of upper casing (2), drain pan (15), cross hairs (1), band element, a side is being provided with transformer (13) in the shell chamber that it is characterized in that being formed by drain pan (15) and upper casing (2), opposite side is being provided with the printed board (7) with element, end outside the shell chamber is being provided with the cross hairs (1) that links to each other with output circuit, and other end bottom is being provided with the power plug (16) that links to each other with the transformer incoming line; Housing top is being provided with and the hinged protective cover that cooperates of upper casing (2) (9); Be that the upper space that itself and upper casing (2) and upper casing base plate surround is the rechargeable battery storehouse under this protective cover; In addition, the side of described drain pan (15) is being provided with polarity switch (5) and charge power supply output switch (16).
Two polarity indicator lights (4,11) and one group of charging indicator light (8) are being set in the described rechargeable battery logical sequence; In addition, two Battery pack pole plates (3,12) are being set also in this battery logical sequence, a pole plate in each Battery pack pole plate is made of the upset reed of torsion spring control.
Described mains charger, its operation control circuit is made up of charging circuit and the adjustable output circuit of polarity of a step-down rectifying circuit and two parallel connections; Wherein said step-down rectifying circuit is made up of transformer (13), charge power supply output K switch 1 and a bridge rectifier; Described charging circuit is by resistance R
1～R
44 resistance and two light-emitting diodes form, and be parallel in the rectifying output circuit respectively; Described polarity conditioned circuit is by polarity switch K
2And resistance R
5And light-emitting diode D

8Form, this circuit is parallel to rectifying output circuit and does not hold, and is connected in cross hairs (1).
Described charge power supply output K switch
1, three 6V, 4.5V, the 3V tap with the transformer output is slidingly connected respectively.
Mains charger according to above technical scheme design, not only volume is little, easy to carry, collection is easy, and output voltage has 3V, 4.5V, 6V, the selection applicability is strong, both positive and negative polarity is adjustable, charging the time have fast, in, slow adjustable function, because an end pole piece in rechargeable battery storehouse can overturn, make it both can be used for 5 simultaneously
#Battery also can be used for 7
#Battery; The cross hairs that matches with machine can match it with any machine in addition.
Accompanying drawing 1 is the structural representation of mains charger;
Accompanying drawing 2 is the utility model assembling schematic diagram;
Accompanying drawing 3 is a line map of the present utility model.
Further describe the utility model below in conjunction with accompanying drawing, and provide embodiment.
Mains charger shown in the figure is made up of cross hairs (1), upper casing (2), upset pole piece (3), polarity indicator light (4), polarity switch (5), charge power supply output switch (6), printed board (7), protective cover (9), spring (10), battery polar sheet (12), transformer (13), drain pan (15), latch (16).
Can enter operating state as long as in actual use this device is directly inserted power supply.At this moment as long as we stir the reversal switch (5) and the switch of power supply output (6) of drain pan (15) limit portion, just can obtain the voltage of 3V, 4.5V, any polarity of 6V from cross hairs (1) crosshead, simultaneously if the output of positive polarity then indicator light (11) is bright, show ruddiness, negative polarity exports that then indicator light (4) is bright, shows green glow.
During charging, with 7
#Battery is directly packed in the rechargeable battery storehouse, is stuck between the two-plate, and at this moment indicator light (8) shows bright; As will be to 5
#Battery charge then should make the battery chucking with one group of pole plate upset in the battery logical sequence, and it is bright that indicator light (8) also shows.As select quick charge then charge power supply switch (6) to be allocated to 6V, get final product as selecting charging at a slow speed then the charge power supply switch to be allocated to 3V.Battery compartment protecting cover (9) can be depressed during charging and make it and the drain pan closure, charging finishes, but flicking upper casing (2) press sheet, loam cake is then strutted.
