Description
본 발명은 휴대용컴퓨터에 관한 것으로서, 보다 상세하게는, 정전기를 제거하며 누설전류가 흐르는 것을 방지할 수 있는 휴대용컴퓨터에 관한 것이다. The present invention relates to a portable computer, and more particularly, to a portable computer capable of removing static electricity and preventing the leakage current.
전자기기는 점점 전력이 낮아지면서 저전압, 초고속으로 동작할 뿐만 아니라, 외관상의 미관을 고려하여 부분적으로나 혹은 전체적으로 금속구조물 등으로 케이싱을 만들게 되어 정전기에 매우 취약한 구조를 가지고 있다. As electronic devices become more and more low in power, they operate at low voltage and ultra-high speed, and have a structure that is very vulnerable to static electricity by making casings of metal structures or the like partially or entirely in consideration of appearance.
이러한 전자기기 중 휴대용컴퓨터는 팜레스트(palmrest) 부위의 금속부위를 섀시 그라운드(chassis ground)와 완전히 플로팅(floating)시켜 누설전류의 유입을 방지하였으나 정전기 문제에 있어 취약하다. Among these electronic devices, the portable computer completely floats the metal part of the palm rest part with the chassis ground to prevent leakage current, but is vulnerable to the static electricity problem.
특히, 팜레스트 부분은 사람의 손이 많이 가기 때문에 습기가 부족한 건조한 환경에서는 정전기 발생이 쉬우며, 이는 시스템의 오동작이나 파워 셧다운(shut down) 혹은 시스템의 리부트(reboot) 등의 문제를 야기시킨다. In particular, the palm rest area is easy to reach due to the human hand, so it is easy to generate static electricity in a dry environment where moisture is insufficient. This causes problems such as a malfunction of the system, a power shutdown or a reboot of the system. .
이러한 정전기 문제를 해결하기 위해, 팜레스트 부분을 회로의 접지 부위에 연결하게 되면 시스템에서 발생되는 누설전류가 팜레스트 부분에 흐르는 문제가 있다. In order to solve this static electricity problem, when the palm rest part is connected to the ground part of the circuit, a leakage current generated in the system flows through the palm rest part.
따라서, 본 발명의 목적은, 정전기를 제거하며 누설전류가 흐르는 것을 방지할 수 있는 휴대용컴퓨터를 제공하는 것이다. It is therefore an object of the present invention to provide a portable computer which can eliminate static electricity and prevent the leakage current from flowing.
상기 목적은, 본 발명에 따라, 회로그라운드를 가진 본체와, 상기 본체의 일면에 마련된 금속재질의 팜레스트부를 갖는 휴대용컴퓨터에 있어서, 상기 팜레스트부와 상기 회로그라운드를 전기적으로 상호 연결시키는 연결라인과; 상기 연결라인 내에 마련되는 적어도 하나의 제너다이오드를 포함하는 것을 특징으로 하는 휴대용컴퓨터에 의해 달성된다.According to the present invention, a portable computer having a main body having a circuit ground and a metal palm rest portion provided on one surface of the main body, the connection line for electrically interconnecting the palm rest portion and the circuit ground; and; It is achieved by a portable computer, characterized in that it comprises at least one zener diode provided in the connection line.
이하에서는 첨부도면을 참조하여 본 발명에 대해 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 휴대용컴퓨터의 사시도이다. 도면에 도시된 바와 같이, 본 휴대용컴퓨터(1)는, 마더보드를 비롯한 다수의 하드웨어가 장착된 본체(3)와, 본체(3)로부터의 영상신호를 표시하는 디스플레이장치(5)와, 키입력을 위한 키보드(7)와, 마우스의 역할을 하는 터치패드(미도시)와, 터치패드의 양단에 마련되는 팜레스트부(9)를 포함한다. 여기서, 팜레스트부(9)는 금속재질로 되어 있다. 1 is a perspective view of a portable computer according to the present invention. As shown in the figure, the portable computer 1 includes a main body 3 equipped with a plurality of hardware including a motherboard, a display device 5 for displaying image signals from the main body 3, and a key. A keyboard 7 for input, a touch pad (not shown) serving as a mouse, and a palm rest portion 9 provided at both ends of the touch pad. Here, the palm rest part 9 is made of metal.
도 2는 본 발명에 따른 휴대용컴퓨터(1)의 구성도이며, 도 3은 도 2의 회로도이다. 2 is a block diagram of a portable computer 1 according to the present invention, and FIG. 3 is a circuit diagram of FIG.
도 2에 도시된 바와 같이, 본 휴대용컴퓨터(1)는 본체(3)의 일면에 마련된 금속재질의 팜레스트부(9)와, 본체(3) 내부에 마련된 회로그라운드(15)와, 팜레스트부(9)와 회로그라운드(15)를 전기적으로 상호 연결시키는 연결라인(17)과, 연결라인(17) 내에 마련된 적어도 하나의 제너다이오드(13)를 포함한다. As shown in FIG. 2, the portable computer 1 includes a palm rest portion 9 made of metal provided on one surface of the main body 3, a circuit ground 15 provided inside the main body 3, and a palm rest. And a connecting line 17 electrically connecting the unit 9 and the circuit ground 15 to each other, and at least one zener diode 13 provided in the connecting line 17.
팜레스트부(9)와 회로그라운드(15)는 최소 약 30 mil 정도를 유지해야 하며, 이 유지되는 간격을 연결라인(17)을 통해 상호 연결시킨다. The palm rest portion 9 and the circuit ground 15 should maintain at least about 30 mils, and the gaps are interconnected through the connection line 17.
연결라인(17)은 팜레스트부(9)와 회로그라운드(15)를 전기적으로 연결시키기 위한 전선을 포함한다. The connection line 17 includes an electric wire for electrically connecting the palm rest part 9 and the circuit ground 15.
제너다이오드(13)는 캐소드에 소정의 제너항복전압 이하의 전압이 인가될 때에는 도통하지 않으나, 캐소드에 제너항복전압 이상의 전압이 인가될 때에는 도통한다. The zener diode 13 does not conduct when a voltage below the predetermined zener breakdown voltage is applied to the cathode, but conducts when a voltage above the zener breakdown voltage is applied to the cathode.
본체(3) 내부에서 누설전류가 발생된 경우에 제너다이오드(13)의 캐소드에는 도 3에 도시된 바와 같이, 팜레스트부(9)의 그라운드(P_GND)가 인가되는 상태이므로 제너다이오드(13)는 도통되지 않는다. 이에, 본체(3) 내부에서 발생된 누설전류가 팜레스트부(9)로 흐르는 것을 방지할 수 있다. When a leakage current is generated in the main body 3, the zener diode 13 is applied to the cathode of the zener diode 13 because the ground P_GND of the palm rest part 9 is applied to the cathode of the zener diode 13. Is not conducting. Thus, leakage current generated inside the main body 3 can be prevented from flowing to the palm rest part 9.
반면, 정전기와 같은 고전압이 제너다이오드(13)의 캐소드에 인가된 경우 제너다이오드(13)는 도통되므로 정전기는 회로그라운드(D_GND)(15)로 바이패스된다. 이로써, 정전기를 제거할 수 있다. On the other hand, when a high voltage such as static electricity is applied to the cathode of the zener diode 13, the zener diode 13 is conductive, so that static electricity is bypassed to the circuit ground D_GND 15. Thereby, static electricity can be removed.
이와 같이, 본 발명은 팜레스트부와 회로그라운드를 적어도 하나이 제너다이오드를 통과하여 전기적으로 상호 연결시킴으로써, 정전기를 제거하며 누설전류가 흐르는 것을 방지할 수 있도록 한다. As described above, the present invention allows at least one of the palm rest portion and the circuit ground to be electrically interconnected through the zener diode to remove static electricity and prevent leakage current from flowing.
본 발명은 상술한 실시예에 한정되지 않으며 본 발명의 사상 내에서 당업자에 의한 변형이 가능함은 물론이다. The present invention is not limited to the above-described embodiment and can be modified by those skilled in the art within the spirit of the invention.
이상 설명한 바와 같이, 본 발명에 따르면, 정전기를 제거하며 누설전류가 흐르는 것을 방지할 수 있는 휴대용컴퓨터가 제공된다. As described above, according to the present invention, a portable computer capable of removing static electricity and preventing a leakage current from flowing is provided.
