Abstract
A charger comprises a casing. A power supply connector, a transformer and a battery charging interface are arranged inside the casing. The input end of the transformer is connected with the power supply connector, and the output end of the transformer is connected with the battery charging interface. An electromagnetic switch, a circuit breaker, a light-emitting diode and a current transformer are arranged on a circuit where the output end of the transformer is connected to the battery charging interface. One channel of the electromagnetic switch is connected with the light-emitting diode and the current transformer, and the other end of the electromagnetic switch is connected with the circuit breaker. The transformer reduces voltage to an appropriate value during charging to connect the channel between the electromagnetic switch, the light-emitting diode and the current transformer due to the change of the current, and then the charger begins to charge. When the charging finishes, the current transformer operates to enable the electromagnetic switch to operate, the electromagnetic switch is connected with the circuit breaker at the time, and outage of the charger is realized. By the means of the charging, when charging finishes, the power can be powered off timely, thereby avoiding damage to the battery if the battery continues to be charged for a long time when the charging finishes, preventing fire hazard accidents caused by heating of the battery, and being capable of saving electric energy.
Description
Technical field
The utility model relates to a kind of charging device, is specifically related to a kind of battery charger.
Background technology
At present, when charger is given the electrical appliance battery charge, often judge according to indicator light whether the electrical appliance battery is full of, yet when the electrical appliance battery is full of electricity, people often forget timely disconnection charger power supply, and the electrical appliance battery is very easily burnt out and possible initiation fire accident through long-time charging after being full of electricity more like this.
Summary of the invention
The purpose of this utility model is to provide a kind of charger, when this charger finishes for the electrical appliance battery charge, can realize automatic circuit break function.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of charger comprises housing, and enclosure interior has power connection, transformer and battery charge interface, and the input of transformer connects power connection, and the output of transformer connects the battery charge interface; Transformer output to the circuit that the battery charge interface connects is provided with electromagnetic switch, shelves, light-emitting diode, current transformer open circuit; A path of electromagnetic switch connects light-emitting diode, current transformer, and the other end connects the shelves that open circuit.
Path between above-mentioned transformer and the electromagnetic switch is provided with protective resistance.
The beneficial effects of the utility model are: transformer can drop to appropriate value with voltage during charging, because electric current changes and electromagnetic switch to be connected with the path of light-emitting diode, current transformer begin to charge, the current transformer effect made the electromagnetic switch action when charging was finished, this moment, electromagnetic switch was received the shelves that open circuit, and realized the charger outage.This kind charging modes can in time cut off the power supply after charging is finished, and having avoided charging to finish the back and having continued the infringement of long-time charging, and having stopped the fire incident that the battery heating is caused battery, and the energy saves energy.The utility model circuit structure is simple, and is easy to operate.
Description of drawings
Accompanying drawing is a circuit connection diagram of the present utility model.
The drawing explanation:
1. power connection; 2. transformer; 3. protective resistance; 4. electromagnetic switch; 5. light-emitting diode; 6. current transformer; 7. battery charge interface; 8. shelves open circuit.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, but be not restriction the utility model.
Referring to accompanying drawing, a kind of charger of the utility model comprises housing, and enclosure interior has power connection 1, transformer 2 and battery charge interface 7, and the input of transformer 2 connects power connection 1, and the output of transformer 2 connects battery charge interface 7; Transformer 2 outputs to the circuit that battery charge interface 7 connects is provided with electromagnetic switch 4, shelves 8, light-emitting diode 5, current transformer 6 open circuit; A path of electromagnetic switch 4 connects light-emitting diode 5, current transformer 6, and the other end connects the shelves 8 that open circuit.Path between transformer 2 and the electromagnetic switch 4 is provided with protective resistance 3.
Transformer can drop to appropriate value with voltage during charging, because electric current changes and electromagnetic switch to be connected with the path of light-emitting diode, current transformer begin to charge, the current transformer effect made the electromagnetic switch action when charging was finished, and this moment, electromagnetic switch was received the shelves that open circuit, and realized the charger outage.This kind charging modes can in time cut off the power supply after charging is finished, and having avoided charging to finish the back and having continued the infringement of long-time charging, and having stopped the fire incident that the battery heating is caused battery, and the energy saves energy.
