Abstract
The utility model relates to a safety charger, in particular to a charger for charging for a common dry battery. A box cover switch (3) is arranged in the shell body (1) of a charger; the switch is connected with a charge power supply and a charging circuit (5); a box cover (2) of the charger is buckled; the switch button (4) of the box cover is contacted with the box cover; the switch is closed; the power supply can be switched on. The box cover is opened; the switch button is isolated from the box cover; the switch is opened; the power supply is cut off. The utility model has the advantages of reasonable structure, high safety, uniform charging current assignment, good charging effect, etc. and is in particular suitable for charging for the common dry battery.
Description
The utility model relates to a kind of battery charger, particularly the charger that general dry battery is charged.
At present, general dry battery is advanced the general constant-current circuit that adopts of charging.Because voltage is higher in the charger housing, use very dangerously, when opening the charger lid, put into or when taking out battery, electric shock accidents takes place easily; In addition, existing current charging circuit is when charging to the two-way battery, and charging current is distributed uneven, influences charging effect.
The utility model purpose is to overcome above-mentioned shortcoming of the prior art and a kind of safe battery charger is provided, and is safe and reliable, improves charging effect.
Goal of the invention of the present utility model is achieved by the following technical solution: the lid switch is set in the charger housing, this switch is connected with charging circuit with charge power supply, buckles the charger lid, and the lid shift knob contacts with lid, switch closure, energized; Open the lid, shift knob separates with lid, and switch opens is cut off the electricity supply.
The electric current distributed uniform is divided into two groups with rechargeable battery when making the two-way battery charge, constitutes network by some diodes by series, parallel, to two Battery packs each with the half-wave charging, make two Battery pack charging current distributed uniform.
The utlity model has characteristics such as rational in infrastructure, safe and reliable, charging current distributed uniform, charging effect height, be specially adapted to general dry battery is advanced charging.

Fig. 3 is the utility model electrical schematic diagram.
Below with reference to accompanying drawings, further specify the utility model by embodiment
In an embodiment, lid switch (3) is set in the charger housing (1), this switch is connected with charging circuit (5) with charge power supply, when the lid of buckling charger (2), lid shift knob (4) contacts with lid, with button down, switch closure, energized; Open the lid, shift knob (4) separates with lid, relies on the effect of spring (6), and switch opens is cut off the electricity supply, and ensures safety.The electric current distributed uniform is divided into two groups with rechargeable battery when making the two-way battery charge, constitutes network by some diodes by series, parallel, to two Battery packs each with the half-wave charging, make two Battery pack charging current distributed uniform.In the negative half cycle of the positive B of alternating current A, electric current is got back to the B end by parallel resistance R1 capacitor C, battery E1, diode V5, V9, V11, V8, V2, resistance R 2, finishes battery E1 is charged; In the positive half cycle of the negative B of A, electric current is got back to the A end by resistance R 2, battery E2, diode V6, V10, V12, V7, V1, shunt capacitance C resistance R 1, finishes the charging to battery E2.
Claims (2)
1, a kind of safe charging device with housing (1), charging circuit (5), lid (2), it is characterized in that lid switch (3) is arranged in the housing (1), this switch is connected with charging circuit (5) with charge power supply, buckle charger lid (2), lid shift knob (4) contacts with lid, switch closure, energized; Open the lid, shift knob separates with lid, and switch opens is cut off the electricity supply.
2, the safe charging device according to claim 1, it is characterized in that said charging circuit (5) is divided into two groups with rechargeable battery, constitute network by some diodes by series, parallel, each charges with half-wave to two Battery packs, makes two Battery pack charging current distributed uniform.
