Description
본 발명은 이동통신 단말기를 침수로부터 보호하는 기술에 관한 것으로, 특히 단말기가 어느 방향으로 침수되더라도 사전에 배터리 전원을 차단하여 단말기의 회로 구성품을 보호할 수 있도록 한 이동통신 단말기의 침수 보호 장치에 관한 것이다.The present invention relates to a technology for protecting a mobile communication terminal from flooding, and more particularly, to an inundation protection device of a mobile communication terminal capable of protecting circuit components of the terminal by cutting off battery power in advance in any direction when the terminal is flooded. will be.
종래의 이동통신 단말기에서의 침수 보호 방법에는 수동적인 리트머스 부착방법과 능동적인 보호 회로의 사용방법이 있었다. In the conventional flood protection method in the mobile communication terminal, there was a passive litmus attachment method and an active protection circuit.
상기 수동적인 리트머스 부착방법은 사전에 회로를 보호하기 위한 방법이 아니라 차후에 확인하기 위한 방법이다. 또한, 상기 능동적인 보호 회로의 사용방법은 침수로부터 충전기를 보호하기 위한 방법이다. The passive litmus attaching method is not a method for protecting the circuit in advance, but a method for later confirmation. In addition, the method of using the active protection circuit is a method for protecting the charger from flooding.
이와 같이 종래 이동통신 단말기의 침수 보호 방법에 있어서 수동적인 리트머스 부착방법은 단순히 차후에 피해 여부를 확인하기 위한 것이고, 능동적인 보호 회로의 사용방법은 침수로부터 충전기 자체만을 보호하기 위한 것이므로, 이들 모두 회로 구성품이 임의의 방향으로 침수되는 것에 대해 보다 확실하게 대응할 수 없는 결함이 있었다.As described above, the passive litmus attaching method in the flooding protection method of the conventional mobile communication terminal is simply to check whether there is damage later, and the active protection circuit is used only to protect the charger itself from flooding. There existed a defect which cannot respond more reliably about being immersed in this arbitrary direction.
따라서, 본 발명의 목적은 회로 구성품이 장착되는 인쇄회로기판의 외곽에 그라운드 패턴과 센서 패턴을 설치하고 침수로 인해 이들이 쇼트될 때 배터리 전원을 차단하도록 하는데 있다.Accordingly, an object of the present invention is to install a ground pattern and a sensor pattern on the outside of a printed circuit board on which circuit components are mounted, and to cut off battery power when they are shorted due to flooding.
본 발명은 회로 구성품이 장착되는 인쇄회로기판의 외곽을 따라 소정의 간격을 두고 설치된 그라운드 패턴 및 센서 패턴과; 상기 센서 패턴과 연결되고, 침수에 의해 그 그라운드 패턴 및 센서 패턴이 쇼트되는 것을 검출하여 그에 따른 침수 검출신호를 출력하는 침수센서와; 상기 침수센서로부터 침수 검출신호가 입력될 때 배터리 전원을 차단하는 배터리 보호회로로 구성함을 특징으로 한다. The present invention includes a ground pattern and a sensor pattern provided at predetermined intervals along the outer edge of the printed circuit board on which the circuit components are mounted; An immersion sensor connected to the sensor pattern and detecting the ground pattern and the sensor pattern shorted by the immersion and outputting a submerged detection signal accordingly; And a battery protection circuit that cuts off battery power when the immersion detection signal is input from the immersion sensor.
이하, 본 발명을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described.
도 1은 본 발명에 의한 이동통신 단말기의 침수 보호 장치의 일실시 구현예를 보인 개략도로서 이에 도시한 바와 같이, 여러 회로 구성품(1A)이 장착되는 인쇄회로기판(1)의 외곽을 따라 띠 형태로 형성한 그라운드 패턴(2)과; 상기 인쇄회로기판(1) 상에서 상기 그라운드 패턴(2)과 소정 간격을 두고 그 그라운드 패턴(2)과 동일 형태로 형성한 센서 패턴(3)과; 침수에 의해 상기 그라운드 패턴(2)과 센서 패턴(3)이 쇼트되는 것을 검출하여 그에 따른 침수 검출신호를 출력하는 침수센서(4)를 포함시켜 구성한 것으로, 이와 같이 구성한 본 발명의 작용을 첨부한 도 2를 참조하여 상세히 설명하면 다음과 같다.1 is a schematic view showing an embodiment of an inundation protection device for a mobile communication terminal according to the present invention. As shown therein, a stripe shape is formed along the periphery of a printed circuit board 1 on which various circuit components 1A are mounted. A ground pattern (2) formed of; A sensor pattern (3) formed on the printed circuit board (1) in the same shape as the ground pattern (2) at a predetermined distance from the ground pattern (2); Including the submersion sensor 4 which detects that the ground pattern (2) and the sensor pattern (3) is shorted by immersion and outputs the immersion detection signal accordingly, the operation of the present invention configured as described above A detailed description with reference to FIG. 2 is as follows.
평상시에는, 여러 회로 구성품(1A)이 장착되는 인쇄회로기판(1)의 외곽을 따라 나란히 형성된 그라운드 패턴(2)과 센서 패턴(3)이 전기적으로 분리되어 있으므로, 침수센서(4)가 센서 패턴(3)을 통해 공급되는 "하이" 신호를 검출하게 된다. Since the ground pattern 2 and the sensor pattern 3 which are formed side by side along the periphery of the printed circuit board 1 on which the various circuit components 1A are usually mounted are electrically separated, the immersion sensor 4 is a sensor pattern. The "high" signal supplied through (3) is detected.
그러나, 이동통신 단말기가 침수되는 경우 상기 인쇄회로기판(1)의 외곽에 나란히 형성된 그라운드 패턴(2)과 센서 패턴(3) 중 해당 방향으로 물이 스며들게 되고, 이에 의해 그 그라운드 패턴(2)과 센서 패턴(3)이 전기적으로 쇼트된다.However, when the mobile communication terminal is inundated, water is permeated in the corresponding direction among the ground pattern 2 and the sensor pattern 3 formed side by side on the outside of the printed circuit board 1, whereby the ground pattern 2 and The sensor pattern 3 is electrically shorted.
따라서, 상기 센서 패턴(3)을 통해 공급되는 "하이" 신호가 그라운드 패턴(2)으로 뮤팅되어 상기 침수센서(4)가 "로우" 신호를 검출하게 되는데, 이 신호가 바로 침수 검출신호이다.Therefore, the "high" signal supplied through the sensor pattern 3 is muted to the ground pattern 2 so that the submersion sensor 4 detects the "low" signal, which is the submersion detection signal.
이때, 상기 침수센서(4)는 침수 검출신호를 배터리 보호회로(도면에 미표시)에 출력하게 되고, 이때 그 배터리 보호회로에 의해 배터리로부터 출력되는 전원이 차단된다.At this time, the immersion sensor 4 outputs the immersion detection signal to the battery protection circuit (not shown), the power output from the battery is cut off by the battery protection circuit.
이상에서 상세히 설명한 바와 같이 본 발명은 회로 구성품이 장착되는 인쇄회로기판의 외곽에 그라운드 패턴과 센서 패턴을 설치하고 침수로 인해 이들이 쇼트되는 것을 검출하여 배터리 보호회로가 동작되도록 함으로써, 침수로 인한 이동통신 단말기의 피해를 최소화할 수 있는 효과가 있다. As described in detail above, the present invention installs a ground pattern and a sensor pattern on the periphery of a printed circuit board on which circuit components are mounted, and detects that the short circuit occurs due to immersion so that the battery protection circuit is operated. There is an effect that can minimize the damage of the terminal.
