Abstract
The utility model relates to a mini-charger, adopting two capacitors for depressurization, solving the disadvantage that a capacitor adopted for depressurization is unsafe in the past. The mini-charger is also provided with multiple sets of charging plug jacks for meeting the requirements of different charging voltage. The mini-charger has simple structure, convenient use, electricity saving and safety.
Description
The utility model is a charging electrical equipment, is specially adapted to civil power to general dry battery and the charging of small-sized nickel-cadmium cell.
In the past with the charger of civil power, useful transformer step-down is useful capacitor step-down also, but takes advantage of entirely with the capacitance decompression uneasiness, so limit its use.
The utility model has solved with the unsafe problem of capacitance decompression from circuit, and can export the different charging voltage values of many groups.
Technical solution of the present utility model realizes as follows: the live wire of civil power is connected in series capacitor respectively with ground wire, after rectification, seal in some groups of charge circuits, each charge circuit is made up of voltage-stabiliser tube, light-emitting diode, jack and diode, and all jacks are by the contact short circuit.Every group of charge circuit formed shunt regulating circuit by light-emitting diode series connection voltage-stabiliser tube, and by the jack output charging of forward diode by correspondence, voltage-stabiliser tube can be by the magnitude of voltage decision of required charging.This circuit working process is that circuit inserts civil power, and charge circuit all was not short-circuit condition when all jacks inserted plug, but can not make circuit or element that any damage takes place because of its short circuit current is less.Insert corresponding charging jack according to different charging voltage values during charging and charge, this loop voltage-stabiliser tube conducting light-emitting diode indication was bright when electricity was sufficient.Owing between voltage stabilizing output and charging jack, seal in forward diode, the discharge process of battery can not take place, and realize automatically shutting down of charging process.
Small and exquisite, the easy to use and power saving safety of the utility model structure, and be provided with many group magnitude of voltage jacks, with the needs of suitable different charging voltages.This device also can cooperate with other electrical equipment increases its charge function.
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
Accompanying drawing is a circuit diagram of the present utility model.Capacitor C 1, C2 link to each other with civil power live wire, ground wire respectively, form bridge rectifier through capacitor C 1, C2 by D1～D4, some groups of charge circuits of bridge rectifier output serial connection.Every group of charge circuit formed shunt regulating circuit by voltage-stabiliser tube DZ serial connection LED, seals in forward diode Di between voltage stabilizing output and charging jack JK.All charging jack JK are by its contact short circuit, and each voltage-stabiliser tube DZ that organizes charge circuit can select various voltage stabilizing values according to charging voltage.The charging jack JK that only needs charging plug is inserted corresponding voltage during charging is chargeable, when electricity is sufficient the LED indication bright, charging circuit automatically shuts down.
