본 발명은 차량용 배터리 센서의 제조 방법에 관한 것으로 더 상세하게는 차량용 배터리의 과충전을 방지하는 배터리 센서의 제조 원가를 절감하고, 내구성을 증대시킬 수 있도록 발명된 것이다.The present invention relates to a method for manufacturing a battery sensor for a vehicle, and more particularly, to reduce the manufacturing cost of the battery sensor for preventing overcharging of a vehicle battery, and is invented to increase durability.

일반적으로 자동차에는 엔진의 점화장치뿐만 아니라, 실내등, 오디오 장치, 공조장치 등과 같이 전기 전원을 공급받아 작동하는 다양한 전기 장치들이 있으며, 이러한 전기 장치들은 차량용 배터리 및 발전기에 의해 전기 전원을 공급받아 작동하는 것이다.In general, automobiles have various electric devices that operate by being supplied with electric power, such as indoor lighting, audio devices, air conditioning devices, as well as engine ignition devices, and these electric devices are operated by electric power supplied by a vehicle battery and a generator. will be.

상기 차량용 배터리는 자동차에서 사용되는 전기 장치들에 전원을 공급하여 방전되며, 일정량 이상으로 방전될 경우 발전기로부터 충전되어 사용되는 것이다.The vehicle battery is discharged by supplying power to the electrical devices used in the automobile, and is discharged from a generator when used in a predetermined amount or more.

상기 발전기는 엔진의 크랭크축과 연결된 크랭크 풀리에 의해 벨트로 연결되어 구동됨으로써 차량용 배터리를 충전함은 물론 주행 중 자동차에서 사용되는 전기 장치들에 전원을 공급하는 것이다.The generator is connected to the belt by a crank pulley connected to the crankshaft of the engine and driven to charge the vehicle battery as well as to supply electric devices used in the vehicle while driving.

상기 차량용 배터리와 발전기 사이에는 차량용 배터리의 전류, 전압, 온도를 측정하여 발전기의 작동을 제어하는 배터리 센서가 구비된다.Between the vehicle battery and the generator is provided with a battery sensor for controlling the operation of the generator by measuring the current, voltage, temperature of the vehicle battery.

상기 배터리 센서는 차량용 배터리의 과충전 및 방전을 방지하는 것으로, 차량용 배터리의 내부 전원이 부족하면 발전기를 작동시켜 충전 작동이 이루어지도록 하며, 차량용 배터리로 일정량 이상의 전원이 충전되면 발전기의 작동을 정지시켜 과충전을 방지하는 것이다.The battery sensor prevents overcharging and discharging of the vehicle battery. When the internal power supply of the vehicle battery is insufficient, the battery sensor operates to generate a charging operation. When the vehicle battery is charged with a predetermined amount or more, the generator stops the operation of the generator to overcharge. To prevent.

상기 배터리 센서는 저항 양단에 발생하는 전압으로 전류 값을 측정하는 션트 저항과, 상기 션트 저항이 접속되며 배터리의 전류, 전압, 온도를 측정할 수 있도록 표면 실장(SMT;Surfce Mount Technology)된 인쇄회로기판(PCB;Printed Circuit Board)과; 상기 션트 저항 및 인쇄회로기판이 접속되며, 배터리에 연결되는 터미널부재와; 상기 션트 저항, 인쇄회로기판, 터미널부재의 외측을 감싸 보호하는 하우징부재를 포함한다.The battery sensor includes a shunt resistor measuring a current value using a voltage generated across the resistor, and a printed circuit (SMT; Surface Mount Technology) connected to the shunt resistor so as to measure current, voltage, and temperature of the battery. A printed circuit board (PCB); A terminal member connected to the shunt resistor and the printed circuit board and connected to a battery; And a housing member surrounding and protecting the shunt resistor, the printed circuit board, and the terminal member.

상기 배터리 센서의 하우징부재는 션트 저항, 인쇄회로기판, 터미널부재가 접속된 상태에서 핫 멜트(Hot Melt)로 포장하여 외곽 형상화되는 것이 일반적이다.The housing member of the battery sensor is generally packaged with a hot melt in the state where the shunt resistor, the printed circuit board, and the terminal member are connected to form an outer shape.

즉, 상기 배터리 센서는 션트 저항, 인쇄회로기판, 터미널부재를 각각 접속시키고, 션트 저항 및 터미널부재 사이에 절연체를 삽입한 후 핫멜트로 하우징을 형성함으로써 제조가 완료되며, 통상 차량의 트렁크 내부에 장착되어 사용되고 있는 실정이다.That is, the battery sensor is connected to the shunt resistor, the printed circuit board, and the terminal member, respectively, inserts an insulator between the shunt resistor and the terminal member, and then forms a housing with a hot melt, and is normally mounted inside the trunk of the vehicle. It is being used.

그러나 종래의 차량용 배터리 센서는 하우징이 핫 멜트로 형성되어 핫 멜트의 접착력 및 온도 특성에 따라 차량용 배터리의 전류, 전압, 온도 측정치에서 변화가 발생되어 오작동이 유발되고, 측정치에 대한 신뢰성이 저하되는 문제점이 있었던 것이다.However, in the conventional vehicle battery sensor, the housing is formed of a hot melt, causing a change in current, voltage, and temperature measurement values of the vehicle battery according to the adhesion and temperature characteristics of the hot melt, causing malfunction, and reducing reliability of the measurement. This was there.

It would have been.

또한 차량용 배터리 센서는 핫 멜트로 하우징을 형성함에 있어 인쇄회로기판의 표면 실장된 표면을 보호하도록 형성되고 션트 저항이 외부로 노출되므로 션트 저항이 공기와의 접촉으로 쉽게 산화되어 손상되는 문제점이 있었던 것이다.In addition, the vehicle battery sensor is formed to protect the surface mounted surface of the printed circuit board in forming the housing with the hot melt, and the shunt resistor is exposed to the outside, so that the shunt resistor is easily oxidized and damaged by contact with air. .
