Description
Affiliated technical field
The utility model relates to a kind of battery charger.
Background technology
Existing battery charger, Chong Dian number of batteries is few simultaneously, the charging current instability.
The utility model content
The purpose of this utility model provides that a kind of many, charging current of number of batteries of charging is simultaneously stablized, the electric current in the charging circuit is little, the battery charger of long service life.
For achieving the above object, a kind of battery charger of the utility model, include cabinet, charging contact and the charging circuit that is connected with the charging contact are installed in cabinet, charging contact more than two pairs or two pairs is formed the charging sets of contacts side by side, in the charging sets of contacts that is equipped with on the cabinet more than two groups or two groups.
Above-mentioned battery charger, the charging contact in its each group charging sets of contacts is connected in series.
Above-mentioned battery charger, its each group charging sets of contacts is connected with a cover charging circuit.
Above-mentioned battery charger, its charging circuit includes transformer and bridge rectifier, output at bridge rectifier is connected with voltage-stabiliser tube, this voltage-stabiliser tube and variable resistor are connected in parallel, be connected in parallel by circuit and the voltage-stabiliser tube formed after charging contact or charging sets of contacts and the triode series connection, the base stage of triode is connected with variable resistor.
Above-mentioned battery charger, its charging contact or charging sets of contacts and switch and resistance are formed the discharge circuit loop.
Because the utility model battery charger, its charging contact is formed the charging sets of contacts side by side by the charging contact more than two pairs or two pairs, in the charging sets of contacts that is equipped with on the cabinet more than two groups or two groups, each can give batteries charging to the charging contact, therefore, the utility model can be simultaneously to the multiple batteries charging, and Chong Dian number of batteries is many simultaneously; Because the charging contact in each group charging sets of contacts is connected in series, the electric current in the charging circuit is little, and is not fragile, therefore, and the long service life of the utility model battery charger; Because in charging circuit, charging current is controlled by triode, and the base stage of triode is by voltage-stabiliser tube and variable resistor control, under the constant situation of variable-resistance resistance, charging current is constant, and therefore charging current of the present utility model is stable, helps prolonging the useful life of battery; Because charging current is controlled by triode, and the base stage of triode is regulated the size that variable resistor can change charging current by variable resistor control, therefore, the utility model can strengthen charging current by regulating variable resistor, realizes the quick charge of battery.
