본 고안은 모니터에 설치되는 보안경을 겸하는 전자파차단휠터에 의해 차단된 전자파가 CRT(CATHODE-RAY TUBE)프레임으로 통전되어 소거되도록 하는 전자파 접지장치에 관한 것으로서, 특히 접지단자가 모니터 전·후 방향으로 출몰운동되어 휠터판의 접지면과 접속되도록 고안된 모니터용 전자파차단휠터의 전자파 접지장치에 관한 것이다. 일반적으로 모니터 등을 비롯하여 전자제품으로부터 방사되는 유해한 전자파를 차폐시키는 방식은 여러 가지방식이 알려져 있으나, 이들 대부분은 대개 어스선을 이용하여 쌔시 등에 접지시키는 구조로서 전자파 전류가 접지되도록 하고 있다. 그러나 어스선을 이용하는 전자파 전류접지방식은 어스선을 이루는 와이어 처리가 용이하지 못하기 때문에 어스선처리를 위한 구조가 복잡하게 되고 작업능률의 저하를 초래하게 하므로서 생산성의 저하를 야기하게 하는 복잡적인 문제가 있다. 그러므로 보안경을 겸하는 전자파차단휠터 모니터 CRT 앞에 설치되도록 하는 CRT커버방식의 전자파차단휠터를 개발하는 과정에서 새로운 타입의 전자파 전류접지장치의 채용이 요구되었다.The present invention relates to an electromagnetic grounding device that allows electromagnetic waves blocked by an electromagnetic shielding filter, which also serves as a safety glasses installed on the monitor, to be energized by a CRT (CATHODE-RAY TUBE) frame to be erased. The present invention relates to an electromagnetic wave grounding device for a electromagnetic wave blocking filter for a monitor designed to be sunk and connected to a ground plane of a filter plate. In general, a variety of methods are known to shield harmful electromagnetic waves emitted from electronic products, including monitors, but most of them are grounded to chassis or the like by using an earth wire to allow electromagnetic current to be grounded. However, the electromagnetic current grounding method using an earth wire has a complicated problem of causing a decrease in productivity due to a complicated structure for the earth wire processing and a decrease in work efficiency because the wire processing of the earth wire is not easy. Therefore, in the process of developing the CRT cover type electromagnetic shielding filter that is installed in front of the CRT monitor CRT, which also serves as safety glasses, the adoption of a new type of electromagnetic current grounding device was required.
본 고안은 상기한 점을 감안하여 모니터의 CRT전면에 보안경을 겸하는 전자파차단휠터를 결착시키게 되면 휠터판과 모니터내에 내장되는 CRT프레임이 자동으로 접속연결되도록 하는 전자파 접지장치를 제공하려는데 그 주된 목적이 있는 것이고, 다른 목적은 모니터 조립시에 캐비네트의 손상이 초래되지 않으면서도 조립성이 양호한 전자파차단휠터의 전자파 접지장치를 제공하므로서 생산성 향상을 도모하게 하려는데 있다.In view of the above, the present invention is to provide an electromagnetic wave grounding device for automatically connecting and connecting the filter plate and the CRT frame embedded in the monitor when the electromagnetic shield is combined with the safety glasses on the front surface of the monitor. Another object of the present invention is to provide an electromagnetic wave grounding device of an electromagnetic wave blocking filter having good assembly without damaging the cabinet during assembly of the monitor, thereby improving productivity.
본 고안은 상기의 목적을 달성시키기 위하여 전자파차단휠터의 휠터판 일측에 있는 접지판이 휠터조립시에 모니터의 캐비네트 일측에 설치되는 탄성돌출식 접지단자구와 접지되도록 하므로서 휠터판의 전자파가 접지단자를 통해 CRT프레임으로 통전되도록 한 것으로서, 이하 첨부된 실시 도면에 의거하여 보다 상세히 설명하면 다음과 같다.In order to achieve the above object, the present invention ensures that the ground plate on one side of the filter plate of the electromagnetic wave blocking filter is grounded with the elastic protrusion type terminal block installed on one side of the cabinet of the monitor when the filter is assembled, so that the electromagnetic wave of the filter plate is grounded. As it is to be energized through the CRT frame, it will be described in more detail based on the accompanying drawings, as follows.
제1도에서 (1)은 모니터이고 (10)은 모니터(1)의 CRT(2) 앞에 설치되는 전자파차단휠터를 나타낸 것이다. 전자파차단휠터(10)는 휠터판(11)을 구비하는 상태에서 가스케트(12)에 의해 밀폐되고 결착구(13)(13')와 마운트(14) 및 나사보스(15)(15')와 고정나사(16)에 의해 모니터(1)에 결착되도록 되어 있다.In FIG. 1, reference numeral 1 denotes a monitor and reference numeral 10 denotes an electromagnetic wave blocking filter installed in front of the CRT 2 of the monitor 1. The electromagnetic shielding filter 10 is sealed by the gasket 12 in the state having the filter plate 11, and the fasteners 13, 13 ', the mount 14, and the threaded bosses 15, 15'. And fixing screw 16 are fixed to the monitor 1.
따라서, 본 고안은 휠터판(11)에 의해 차단된 전자파전류가 일측에 고정된 접속편(11a)을 통해 모니터(1)로 흐르도록 접속되는 접지단자구(20)가 모니터(1) 일측냅에 설치되도록 된 것이다.Therefore, the present invention is connected to the ground terminal sphere 20 connected so that the electromagnetic wave current blocked by the filter plate 11 flows to the monitor 1 through the connecting piece 11a fixed to one side. It is intended to be installed on.
접지단자구(20)는 끝단부가 하향절곡된 접촉편(21)을 구비하고 있고 접촉편(21)은 중간에 접지돌기(22)를 가진 지지편(23)으로부터 절곡되어 나은 탄성편(24) 끝부에 절곡되어 길게 형성되도록 되어 있다. 또한, 상기 지지편(23)에는 각각 대향되도록 절곡된 한쌍의 협지편(25)(25')을 구비하게 되고 협지편(25)(25')사이로는 프런트가카바(3) 내부 일측에 형성시킨 이동방지편(4)이 삽입되도록 결합되도록 조립된다.The ground terminal sphere 20 has a contact piece 21 whose end is bent downward, and the contact piece 21 is bent from a support piece 23 having a grounding protrusion 22 in the middle, so that the better elastic piece 24 is provided. It is bent at the end and formed long. In addition, the support piece 23 is provided with a pair of sandwich pieces 25, 25 'bent so as to face each other, and is formed on one side of the front kakab 3 between the sandwich pieces 25, 25'. The movement preventing piece 4 is assembled to be combined to be inserted.
즉, 상기 접지단자구(20)는 제3도 및 제4도에 보인바와 같이 양측에 각각 절곡되어 있는 협지편(25)(25') 사이로 이동방지편(4)이 억지끼움되도록 끼워져서 결합되는 한편, 상기 접지단자구(20)의 접지돌기(22) 외측으로는 제5도의 도시와 같이 이동방지편(4) 양측에 있는 고정보스(4')에 CRT프레임(5)이 나사(6)에 의해 각각 체결되어 고정되는 상태로 결합되므로서 상기 접지단자구(20)의 접지돌기(22)와 CRT프레임(5)이 접촉되어 접지되는 상태로 조립된다. 한편, 접촉편(21)은 프런트카바(3) 일측 전면부(3a)에 뚫린 접속구멍(26)을 통해 외부로 돌출되도록 설치되고 접지돌기(22)는 CRT프레임(5)이 조립되면 그와 접속되도록 구성된다.That is, the ground terminal sphere 20 is coupled to the interference prevention piece (4) is inserted between the pinching pieces (25, 25 ') are bent on both sides as shown in Figures 3 and 4, respectively On the other hand, the CRT frame 5 is screwed to the high information 4 'on both sides of the movement preventing piece 4, as shown in FIG. 5, outside the ground protrusion 22 of the ground terminal sphere 20. By being coupled to each other by being fastened by a fixed state), the ground projection 22 and the CRT frame 5 of the ground terminal sphere 20 is assembled in contact with the ground. On the other hand, the contact piece 21 is installed so as to protrude to the outside through the connection hole 26 drilled in one front portion (3a) of the front cover (3) and the grounding projection (22) and when the CRT frame (5) is assembled Configured to be connected.
이와 같이 구성된 본 고안은 모니터(1)의 CRT(2) 앞으로 전자파차단휠터(10)가 결착되면 휠터판(11)의 접속편(11a)이 자동적으로 접지단자구(20)의 접촉편(21)에 맞닿아 접촉되므로서 접촉편(21)은 약간 내측으로 밀리게 되며 아울러서 탄성편(24)은 밀림반대방향인 바깥쪽으로의 탄성력이 더욱 증가되어 접촉편(21)이 접속편(11a)과의 확실한 접속이 확보된다. 또한, 접촉편(21)은 탄성편(24)에 의해 전·후방향으로의 탄성운동이 가능하기 때문에 모니터(1)의 조립시에 접촉편(21)이 접속구멍(26)쪽으로 밀착되므로서 조립장애 요소가 되지 않게 된다.According to the present invention configured as described above, when the electromagnetic shielding filter 10 is attached to the CRT 2 of the monitor 1, the connecting piece 11a of the filter plate 11 is automatically brought into contact with the ground terminal sphere 20. The contact piece 21 is pushed a little inward as it comes into contact with the c), and the elastic piece 24 further increases the elastic force to the outside in the opposite direction to the sliding direction so that the contact piece 21 is connected to the connecting piece 11a. Secure connection of is secured. In addition, since the contact piece 21 is capable of elastic movement in the front and rear directions by the elastic piece 24, the contact piece 21 is in close contact with the connection hole 26 when the monitor 1 is assembled. It does not become an assembly obstacle element.
한편, 접촉편(21)을 통해서 전자파 전류는 접지돌기(22)와 접지된 CRT프레임(5)으로 흘러 소거되게 되는 것으로서, 상기 접지단자구(20)는 휠터판(11)의 접속편(11a)이 접촉편(22)에 접촉되므로서 가해지는 힘이 작용되어 늘림이 되게 되더라도 이동방지편(4) 양측에 있는 고정보스(4')에 CRT프레임(5)이 나사(6)로서 체결되도록 고정되어 있기 때문에 접속단자구(20) 자체가 이탈방지편(4)으로부터 외측으로 이탈되지 않고 CRT프레임(5)과의 접지가 확실히 이루어지게 된다.Meanwhile, the electromagnetic current flows through the contact piece 21 to the ground protrusion 22 and the grounded CRT frame 5 to be erased. The ground terminal sphere 20 is connected to the connecting piece 11a of the filter plate 11. ) Is contacted with the contact piece 22 so that the CRT frame 5 is fastened as the screw 6 to the high information 4 'on both sides of the movement preventing piece 4 even if the force applied is increased. Since it is fixed, the connection terminal sphere 20 itself is secured to the CRT frame 5 without being separated outward from the separation preventing piece 4.
이와 같이 본 고안은 전자파차단휠터(10)의 조립과 동시에 접지단자구(20)에 의해 휠터판(11)이 접지되는 상태가 되는 한편 조립성이 양호하고, 상기 접지단자구(20)를 프런트카바(3) 내측에 형성되어 있는 이동방지편(4)(리브라고도 명칭됨)에 끼우도록 결합시키는 방식을 사용하므로 조립이 간단하며, 외부의 힘에 따른 자체변형이 없는 앞뒤유동의 탄성구조로서 항상 일정하고 확실한 접지를 도모하게 되는 효과를 제공하게 되는 유용한 고안이다.As described above, the present invention is in a state in which the filter plate 11 is grounded by the ground terminal sphere 20 at the same time as the electromagnetic shielding filter 10 is assembled, and the assemblability is good, and the ground terminal sphere 20 is fronted. It is easy to assemble because it is combined to fit on the movement preventing piece 4 (also called rib) formed inside the cover 3, and it is an elastic structure of front and rear flow without self-deformation according to external force. It is a useful design that will provide the effect of always achieving a constant and reliable grounding.
