본 발명은 휴대용 컴퓨터에 관한 것으로서, 보다 상세하게는 시스템본체와 LCD의 그라운드연결이 용이하고, 전자파방해가 적은 휴대용 컴퓨터에 관한 것이다.       BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable computer. More particularly, the present invention relates to a portable computer that is easily connected to the ground of the system body and the LCD and has low electromagnetic interference.

일반적으로 전자기기에서 기기의 작동시 발생하는 전자파(EMI)는 인체와 주변의 전자장치에 심각한 장애를 유발한다. 특히 휴대용 컴퓨터의 일 예로서 노트북 컴퓨터는 개인이 휴대하여 사용하며 인체와 밀접하게 관련되어 사용하는 장비이기 때문에 여기서 발생하는 전자파에 의한 폐해에 대한 보고가 증가하는 추세에 있다.        In general, electromagnetic waves (EMI) generated by the operation of the device in the electronic device causes serious obstacles to the human body and the surrounding electronic devices. In particular, as an example of a portable computer, a notebook computer is a device that is used by a person and is closely related to the human body, and thus reports on the damage caused by electromagnetic waves are increasing.

또한, 노트북 컴퓨터의 디바이스와 하드웨어의 데이터처리속도가 점점 빨라지고 있으며, 속도가 빨라질수록 전자파(EMI)문제는 더욱 심각하게 고려해야 할 사항이 되고 있다.        In addition, the data processing speed of the devices and hardware of the notebook computer is increasing faster, and as the speed increases, the electromagnetic wave (EMI) problem becomes more serious consideration.

휴대용 컴퓨터(100)는 도 4에 도시된 바와 같이, 데이터를 입력하는 키보드, 주기억장치(하드디스크) 등의 하드웨어와 중앙처리장치(CPU) 및 마더보드와 각종회로가 내장되는 시스템본체(103)와, 시스템본체(103)와 연결되어 데이터를 화상으로 나타내는 LCD패널(Liquid Crystal Display Pannel)(107)의 외관을 형성하는 전면판(105)과 후면판(106)을 갖는 커버로 구성된다.        As shown in FIG. 4, the portable computer 100 includes a system main body 103 in which hardware such as a keyboard for inputting data, a main memory device (hard disk), a central processing unit (CPU), a motherboard, and various circuits are embedded. And a cover having a front panel 105 and a rear panel 106 which are connected to the system main body 103 to form an external appearance of an LCD (Liquid Crystal Display Pannel) 107 that displays data as an image.

시스템본체(103)와 커버는 일단측부가 상호 접촉하여 양측단이 힌지(109)로 결합되고, 힌지(109)에는 전자파를 상쇄시키기 위해 도시 않은 시스템본체(103)의 그라운드가 접지된다.       One end of the system main body 103 and the cover are coupled to each other by the hinge 109, and the hinge 109 is grounded to the hinge 109 so that the ground of the system main body 103 (not shown) is canceled.

휴대용 컴퓨터 중에는 LCD의 전자파방해를 개선시키기 위해 시스템본체의 신호를 LCD에 전달하는 LCD커넥터(108)를 도전성섬유로 실딩(Shielding)하고, LCD커넥터(108)의 일부 단부를 그라운드연결부로 마련하여, 시스템본체(103)내의 그라 운드에 연결하기도 한다.       In the portable computer, in order to improve the electromagnetic interference of the LCD, the LCD connector 108 which transmits the signal of the system body to the LCD is shielded with conductive fiber, and some ends of the LCD connector 108 are provided as ground connection parts. It may also be connected to the ground in the system body 103.

그런데, 이러한 휴대용 컴퓨터(100)는 시스템본체(103)의 그라운드를 힌지(109)에 연결하고, LCD커넥터(108)를 변형해서 와이어를 통해 시스템본체(103)에 연결해야하므로 작업이 용이하지 않다. 또한, 시스템본체(103)의 그라운드가 양측 힌지(109)에 연결되므로 그라운드루프(Loop)가 크게 형성되어 전자파의 차단이 크게 개선되지 않는다.       However, such a portable computer 100 is not easy to work because it is necessary to connect the ground of the system body 103 to the hinge 109, and to deform the LCD connector 108 to connect to the system body 103 through a wire. . In addition, since the ground of the system main body 103 is connected to both hinges 109, the ground loop is largely formed, and the blocking of electromagnetic waves is not greatly improved.

따라서, 본 발명의 목적은, 시스템과 LCD의 그라운드연결이 용이하고, 그라운드루프(Loop)가 작게 형성되어 전자파차단이 향상된 휴대용 컴퓨터를 제공하는 것이다.

On the other hand, the motherboard (not shown) is provided with an LCD connector for applying power and signals so that the screen is displayed on the LCD panel (7).

여기서, 플로피디스크와 하드디스크 등의 컴퓨터하드웨어의 판면에는 소정 너비의 단부를 제외한 내부영역이 절연물질로 코팅되어 있어, 절연되지 않은 외주면을 따라 미세한 전류가 통하게 된다. 따라서, 인접하는 컴퓨터하드웨어와 금속섀시 및 금속실드(35)는 시스템본체(3)의 그라운드를 형성하고, 금속실드(35)에 의해 형성된 그라운드는 양측 힌지(9)에 접지되어 시스템본체(3)내에서 발생되는 전자파를 배출시킨다. Here, the inner surface of the computer hardware, such as the floppy disk and the hard disk, except for the end of the predetermined width is coated with an insulating material, so that a minute current flows along the non-insulated outer circumferential surface. Therefore, the adjacent computer hardware, the metal chassis and the metal shield 35 form the ground of the system body 3, and the ground formed by the metal shield 35 is grounded at both hinges 9 so that the system body 3 is grounded.

In addition, an LCD ground 23 formed of a metal plate is attached to the central region of the bottom surface of the cover back plate 6 in contact with the system main body 3 to come into contact with the system ground 21.

도 2는 도 1의 휴대용 컴퓨터의 닫힌 상태의 측단면도이고, 도 3은 개방 상태의 측단면도이다. 도면에 도시된 바와 같이, 시스템본체(3)의 하우징상판(33)에는 시스템그라운드(21)가 판스프링형태로 돌출 형성된다. 2 is a side cross-sectional view of the portable computer of FIG. 1 in a closed state, and FIG. 3 is a side cross-sectional view of an open state. As shown in the figure, the system ground 21 in the housing upper plate 33 of the system body 3 is formed to protrude in the form of a leaf spring.

시스템그라운드(21)는 역'Ｕ'자형의 단면을 가지며, 일단은 하우징저판(31)에 고정되며, 가로방향으로 절곡된 걸림부(27)가 형성된 타단은 상하로 탄성변형한 다. 그리고, 하우징상판(33)의 내측면에는 'ㄴ'자 형상의 단면을 갖는 시스템그라운드수용부(25)가 마련되어 시스템그라운드(21)의 걸림부(27)를 수용하며 시스템그라운드(21)가 시스템본체(3)의 전기회로와 접촉되지 않도록 한다.The system ground 21 has an inverted 'Ｕ' shaped cross section, one end of which is fixed to the housing bottom plate 31, and the other end of which the engaging portion 27 is bent in the horizontal direction is elastically deformed up and down. In addition, the inner surface of the housing upper plate 33 is provided with a system ground accommodating portion 25 having a 'b' shaped cross section to accommodate the locking portion 27 of the system ground 21, and the system ground 21 is a system ground. Do not make contact with the electric circuit of the main body (3).

본 발명에서 시스템그라운드(21)를 시스템본체(3)에 설치하는 순서는 다음과 같다. 시스템본체(3)의 하우징상판(33)의 외벽면과 금속실드(35)사이에 금속판의 일측을 고정되게 설치한다. 그리고, 하우징상판(33)을 절개하여 금속판의 타측을 통과시켜 외부로 노출시킨 후 역'Ｕ'자 형상으로 완만하게 절곡한 다음 타측을 가로방향으로 절곡하여 걸림부(27)를 마련한다. 그 다음 걸림부(27)를 하우징상판(33)을 통해 시스템본체(3)내로 다시 삽입하여 금속판의 걸림부(27)를 시스템그라운드수용부(25)에 수용시킨다. In the present invention, the system ground 21 is installed in the system main body 3 as follows. One side of the metal plate is fixedly installed between the outer wall surface of the housing upper plate 33 of the system body 3 and the metal shield 35.

이에 의해, 휴대용 컴퓨터(1)를 사용 시에는 커버의 LCD그라운드(23)가 시스템그라운드(21)에 접촉하면서 접지가 이루어지고, 휴대용 컴퓨터(1)의 미사용시에는 시스템그라운드(21)와 LCD그라운드(23)는 미접촉상태가 된다.Thus, the ground is established while the LCD ground 23 of the cover contacts the system ground 21 when the portable computer 1 is in use, and the system ground 21 and the LCD ground when the portable computer 1 is not in use. 23 is in an uncontacted state.

여기서, 상술한 실시 예에서는 시스템본체의 그라운드를 힌지로부터 연결하였으나 시스템본체 내에서 그라운드를 형성하는 금속섀시 또는 금속실드 등에도 연결할 수 있다.Here, in the above-described embodiment, the ground of the system body is connected from the hinge, but it may be connected to the metal chassis or the metal shield that forms the ground in the system body.

또한, 실시 예에서는 시스템본체의 시스템그라운드(21)를 판스프링형태의 금 속판으로 하고, LCD그라운드(23)는 고정된 금속판으로 마련하였으나 다른 형태로 얼마든지 변형할 수 있다. In addition, in the embodiment, the system ground 21 of the system body is made of a metal plate of the leaf spring type, and the LCD ground 23 is provided with a fixed metal plate, but may be modified in any other form.

이러한 구성에 의하여, 휴대용 컴퓨터에서 커버의 양측힌지(9)의 중심영역에 설치된 시스템그라운드(21)와 커버에 마련된 LCD그라운드(23)가 접촉되도록 하여 그라운드를 용이하게 접지 시킬 수 있으며, 그라운드가 양측 힌지(9)의 중심부에 마련되어 그라운드 루프(Loop)가 작게 형성됨으로써 전자파를 효과적으로 감소시킬 수 있다.By such a configuration, the ground can be easily grounded by bringing the system ground 21 installed in the center area of the both sides hinge 9 of the cover into the LCD ground 23 provided in the cover in the portable computer, and the ground being both sides. The ground loop is formed in the center of the hinge 9 so that the electromagnetic waves can be effectively reduced.

이상 설명한 바와 같이, 본 발명에 따르면, 양측 힌지 사이에 시스템그라운드와 LCD그라운드가 접촉되게 마련하여 그라운드연결이 용이하고, 그라운드루프(Loop)가 작게 형성되어 전자파차단이 향상된 휴대용 컴퓨터가 제공된다. As described above, according to the present invention, there is provided a portable computer in which the system ground and the LCD ground are brought into contact between the hinges on both sides, so that the ground connection is easy and the ground loop is formed small so that electromagnetic wave blocking is improved.
