ヤーポツトアダプター。[Scope of Claim for Utility Model Registration] (1) Battery protection that has an energization control means that connects to the power supply port of a jackpot and energizes the car's battery 14 to keep it warm, and stops energizing when the voltage of the battery 14 becomes low. A jar pot adapter for mounting on a vehicle, characterized by having a means. (2) As the protection means, a voltage VzD 1 determined by a resistor 15 and a Zener diode 16 is set as a reference voltage in a circuit using the battery 14 as a power supply voltage, and a voltage VR 3 determined by the voltage division of a plurality of resistors 24 and resistors 25 is set.
comparator 17 that inputs
A request for registration of a utility model characterized in that the device is connected to a relay 20 which turns off when the voltage of the comparator 17 decreases and the output signal of the comparator 17 becomes L0 , stopping the power supply to the battery 14 to the power supply port of the pot. Range: 1. A jar pot adapter for mounting on a vehicle as described in item 1.
