Abstract
The utility model relates to a three-function charger, which relates to the improved invention of chargers. The utility model comprises a transformer B, a rectifying circuit, and a battery holder. The utility model is characterized in that two two-knife four-throw switches K1, K2 and a two-knife two-throw switch K3 are arranged in a charging circuit. The utility model can realize functions of current regulating charging for different batteries, voltage testing, and alternating current-direct current lighting.
Description
The utility model is the improvement invention about charger.
In existing technology, charger is fairly simple usually, generally only is used for the charging of secondary cell, and charging effect is also bad, and circuit structure is generally transformer output and is passed to battery tray, function singleness again through rectification circuit, all can not charge to general dry battery, especially to two deer board batteries.
In view of problems of the prior art, but the utility model aims to provide a kind of circuital current adjusting device that is provided with, utilize the brightness of bulb small electric bulb, electric weight that can the walk through test battery, the user can judge whether battery needs to charge or whether battery charge is sufficient, can realize simultaneously the multiple battery charging, the purpose that alternating current-direct current is lit a lamp.
Technical solutions of the utility model are as follows: comprise transformer B, rectification circuit, battery tray, the common point of one termination, two cuttves, the four throw switch K2 of described transformer B secondary coil, the input of the 1 termination rectification circuit of K2,3 ends of K2 are by resistance R 1, R2 connects the input of rectification circuit, 2 of K2 terminates between R1 and the R2, the output of the following row 1 termination rectification circuit of K1, following row's common point of K1 connects the positive pole of battery tray, battery tray two joint charging negative poles connect the right side of two cuttves, two throw switch K3 and arrange 1 end, one joint charging negative pole connects the left bank common point of K3, the left bank common point of K3 connects the centre position of the secondary coil of transformer B, and right side row's common point of K3 connects the other end of transformer B secondary coil.Following row 2 ends of described K1 connect the negative pole that battery tray two joints charge by bulb L, following row 2 ends of K1 and last row's common point short circuit, and the row's of going up 3 ends of K1 are connected on rectification circuit input end by resistance R 4.
Design three function chargers by the utility model theme, can common old and useless battery be charged, also can more piece charge together simultaneously, can also detect battery and whether be full of electricity, and interchange is lit a lamp by adjusting its charging current.
The utility model has following accompanying drawing
Fig. 1 is the utility model circuit working schematic diagram
Accompanying drawing has been represented operation principle of the present utility model, further describe its enforcement rate below in conjunction with accompanying drawing: comprise transformer B, rectification circuit is by D1, R1, R2, R3 forms, battery tray, the common point of one termination, two cuttves, the four throw switch K2 of described transformer B secondary coil, the input of the 1 termination rectification circuit of K2,3 ends of K2 are by resistance R 1, R2 connects the input of rectification circuit, 2 of K2 terminates between R1 and the R2, the output of the following row 1 termination rectification circuit of K1, following row's common point of K1 is connected on the positive pole of battery tray, battery tray two joint charging negative poles connect the right side of two cuttves, two throw switch K3 and arrange 1 end, one joint charging negative pole connects the left bank common point of K3, the left bank common point of K3 connects the centre position of transformer B secondary coil, and right side row's common point of K3 connects the other end of transformer B secondary coil.Following row 2 ends of described K1 connect the negative pole that battery tray two joints charge by bulb L, following row 2 ends of K1 and last row's common point short circuit, and the row's of going up 3 ends of K1 are connected on rectification circuit input end by resistance R 4.
Two cuttves, four throw switch K1 are the functional switch of three function chargers, and K1 is that battery is charged in the time of 1 grade, and K1 is to light a lamp with battery in the time of 2 grades, and K1 is to light a lamp with the AC low-tension electricity in the time of 3 grades, and K1 is to close " three use device " to quit work in the time of 4 grades.Two cuttves, four throw switch K2 are Gear-shift switches of charging current size.K1 is in the time of 1 grade, have only dropping resistor R3 to insert charging circuit, at this moment common 1#, 2# dry cell are charged, K2 is in the time of 2 grades, R2, R3 insert charging circuit, to 5#, 7# dry battery charge, also at these shelves, K2 is in the time of 3 grades every the charging of nickel-based battery medium current, be every the nickel-based battery low current charge, when interchange was lit a lamp, K2 exchanged the light modulation Gear-shift switch of lighting a lamp, and K3 fills a joint or two batteries change over switches, K3 is in the time of 1 grade, charger fills two batteries, and K3 is in the time of 2 grades, and charger is to fill a batteries.The resistance of described R1, R2, R3 is selected very small, and the pressure drop of circuit inside is just very little like this.
Claims (2)
