Abstract

본 발명은 차량용 공조기의 블로워 모터 구속시, 과전류가 발생되면 이를 차단시켜서 차량의 전장회로 및 모터를 보호할 수 있는 차량용 공조기의 과전류 차단장치에 관한 것으로, 이를 해결하기 위하여 이그리션 스위치의 전원단의 일측에 연결되는 모터와, 이 모터의 타측에 연결되고, 휴즈와 저항으로 구성되어 그 타측은 상기 휴즈와 저항을 통해 스위치에 연결되어 차량용 공조기의 블로워 모터 구속시에 과전류를 차단하는 레지스터로 구성된 과전류 차단장치에 있어서, 과전류를 차단하는 레지스터에 과전류가 발생되면, 이 발생된 과전류가 흐르지 못하도록 높은 저항을 유지시키는 PTC소자를 포함함으로써 차량의 전자회로단을 보호할 수 있으며, 고열로 인한 파손이 없어 반영구적으로 사용한 수 있는 효과가 있다.The present invention relates to an overcurrent blocking device for a vehicle air conditioner that can protect an electric circuit and a motor of a vehicle by blocking it when an overcurrent occurs when the blower motor of the vehicle air conditioner is restrained. A motor connected to one side of the motor, and a resistor connected to the other side of the motor, comprising a fuse and a resistor, the other side of which is connected to a switch through the fuse and a resistor to block an overcurrent when the blower motor of the vehicle air conditioner is restrained. In the overcurrent interruption device, if an overcurrent occurs in a resistor that blocks the overcurrent, the electronic device of the vehicle can be protected by including a PTC element that maintains a high resistance to prevent the generated overcurrent from flowing. There is no effect that can be used semi-permanently.
