Abstract
The utility model discloses an automatic-shut-off charger, composed of a charging circuit and a delaying off circuit. The delaying off circuit comprises two resistors, an electrolytic capacitor, a stabilivolt tube, a triode and a magnetic thill on-off device. One end of one resistor is connected to the charging end signal output terminal of the charging circuit and the other end is successively connected in series to the stabilivolt tube. The other resistor is connected to the triode base. The cathode of the electrolytic capacitor is connected to the contact of the resistor and the stabilivolt tube. The anode of the electrolytic capacitor and the emitter of the triode are connected parallelly to the anode of the charging circuit. The magnetic thill on-off device is connected crossly between the triode collector and the power supply cathode of the charging circuit. Two normally closed contacts of the magnetic thill on-off device are connected in series seperately to the phase wire and the ground wire of the AC power (the main power). The utility model can automatically cut off the main power supply circuit so that the power can be saved and the deformation or damage of chargers and batteries caused by excessive charging can be prevented. The utility model is simple in structure, practical, low in cost, effective and applicable to various chargers.
