Description

전자제품의 접지장치Grounding device for electronic products

본 고안은 모니터와 같은 전자제품에서 EMI 대책의 일환으로 적용되고 있는 접지장치에 관한 것으로서, 더욱 상세하게는 V자형의 어스플레이트가 접지물에 접촉되도록 하는데 있어 밀착력이 향상되도록 개선한 전자제품의 접지장치에 관한 것이다.The present invention relates to a grounding device that is applied as part of an EMI countermeasure in an electronic product such as a monitor. More specifically, the grounding of an electronic product improved to improve the adhesion in contacting the ground with a V-shaped plate. Relates to a device.

일반적으로 디스플레이장치와 같은 전자제품에서의 접지장치는 어스플레이트를 이용한 접지장치가 그 주종을 이루고 있으며, 도 1은 그러한 디스플레이장치의 일측면도를 보여 준다.In general, a grounding device in an electronic product such as a display device is mainly a grounding device using an earth plate, Figure 1 shows one side view of such a display device.

여기서, 접지장치를 구성하고 있는 어스플레이트(10)는 케이스(1) 내부에 설치되는 음극선관(2) 네크부에 장착된 기판쉴드물(3)에 고정되게 설치된다. 또한, 어스플레이트(10)는 V자형의 것이 채용된다.Here, the earth plate 10 constituting the grounding device is fixed to the substrate shield 3 mounted on the neck portion of the cathode ray tube 2 installed in the case 1. In addition, the V-shaped thing is employ | adopted for the earth plate 10. As shown in FIG.

이러한 어스플레이트는 자체가 절곡되어 양측에 접촉편부(11)(11')를 갖는다. 그러므로 백카바(1') 내면에 코팅된 도전체(4)와 접촉되도록 하고, 상기 도전체(4)는 기판프레임(5)과 같은 접지물과 접촉되는 접지가 도모되도록 하고 있다.This earth plate is bent itself and has contact piece portions 11, 11 'on both sides. Therefore, the inner surface of the back cover 1 'is brought into contact with the conductor 4 coated on the inner surface of the back cover 1'.

그리고 어스플레이트(10)는 접촉편부(11)(11')가 탄성을 갖도록 하기 위해 얇은 동판을 이용하여 제조된다. 그러므로 변형이 쉽게 되는 단점을 갖고 있으며 회복력이 약하다. 일단 변형되면 그 자체적으로는 원래대로 복귀되지 않으므로 취급시 어스플레이트(10)의 접촉편부(11)(11')가 설계된 각도보다 더욱 넓은 상태로 벌어지는 변형이 초래되는 경우가 많다. 이 경우 접촉편부(11)(11')가 백카바(1')에 있는 도전체(4)에 완전히 밀착되지 않게 되거나 또는 아예 접촉되지 않으므로서 그라운드 효과의 저조 및 접지불량의 요인을 안고 있다.And the earth plate 10 is manufactured using a thin copper plate in order to make the contact piece portions 11 and 11 'have elasticity. Therefore, it has the disadvantage of being easily deformed and the recovery ability is weak. Once deformed, it does not return to itself as a result, and in many cases, deformation occurs when the contact pieces 11 and 11 'of the earth plate 10 are wider than the designed angle. In this case, the contact piece portions 11 and 11 'are not brought into close contact with the conductors 4 in the back cover 1' or are not in contact with each other, and thus the ground effect is poor and the grounding failure is caused.

본 고안은 상기한 바와 같은 종래의 제반 문제점을 해결하려는 것으로서, V자형의 어스플레이트가 접지물에 접촉되도록 하는데 있어 밀착력을 좋게하여 그라운드 효과를 높이려는데 그 목적이 있다.The present invention is to solve the conventional problems as described above, the purpose is to improve the ground effect by improving the adhesion in the V-shaped earth plate in contact with the ground.

본 고안은 상기한 목적을 달성하기 위하여, 어스플레이트 양측에 있는 접촉편부가 항시 내측방향으로 오므려지는 탄력이 부여되도록 하였다.The present invention, in order to achieve the above object, the contact piece on both sides of the earth plate is to be given the elasticity that is always retracted inward.

따라서, 본 고안은 접지물에 고정되고 양측에 피접지물과 접촉되는 접촉편부를 가진 V자형의 어스플레이트를 갖는 접지장치로서, 상기 접촉편부가 강제당김수단에 의해 내측방향으로 당겨지는 탄력을 갖도록 구성한 것에 그 특징이 있다.Accordingly, the present invention is a grounding device having a V-shaped earth plate having a contact piece that is fixed to the ground and contacted with the grounded object on both sides, wherein the contact piece is configured to have elasticity to be pulled inwardly by a forced pulling means. It has that feature.

또한, 다른 특징으로는 상기 강제당김수단이 압축코일스프링인 것에 있다.Another feature is that the forced pulling means is a compression coil spring.

본 고안을 첨부된 바람직한 실시도면에 의거하여 보다 상세히 설명하면 다음과 같다.When the present invention is described in more detail based on the accompanying preferred embodiments as follows.

도 3 및 도 4는 본 고안에 따른 접지장치를 보여 준다. 여기서 부호 2는 음극선관을 나타낸 것으로서 그 네크부에는 회로기판(6)이 설치되고 그 외부에는 도전성이 있는 기판쉴드물(3)이 설치되어 있다.3 and 4 show a grounding device according to the present invention. Here, reference numeral 2 denotes a cathode ray tube, and a circuit board 6 is provided at its neck portion, and a conductive substrate shield 3 is provided at its outside.

어스플레이트(10)는 접지물이 되는 기판쉴드물(3)에 고정되며, 양측에는 벌어지는 상태의 접촉편부(11)(11')를 구비함으로써 V자 형태의 어스플레이트(10)를 구성한다.The earth plate 10 is fixed to the substrate shield 3 to be grounded, and the V-shaped earth plate 10 is formed by providing the contact piece portions 11 and 11 ′ in the open state on both sides.

또한, 어스플레이트(10)의 접촉편부(11)(11') 중간에는 걸이부(12)(12')를 각각 구비하고 여기에 강제당김수단이 되는 압축코일스프링(13)의 양단부가 걸리도록 설치된다.In addition, hooking portions 12 and 12 'are provided in the middle of the contact piece portions 11 and 11' of the earth plate 10 so that both ends of the compression coil spring 13 serving as a forcing means are caught. Is installed.

따라서, 상기 접촉편부(11)(11')는 항시 내측방향으로 오므려지는 상태의 탄력을 압축코일스프링(13)에 의해 부여받게 된다.Therefore, the contact piece portions 11, 11 'are always given by the compression coil spring 13 the elasticity of the state that is always closed inwardly.

그러므로 취급 도중에 어스플레이트(10)의 접촉편부(11)(11')가 외측방향으로 더욱 벌어지는 상태가 되어도 압축코일스프링(13)의 당김력에 의해서 내측으로 다시 오므려지는 상태가 된다.Therefore, even when the contact piece portions 11 and 11 'of the earth plate 10 are further opened in the outward direction during handling, they are retracted inward by the pulling force of the compression coil spring 13.

또한, 상기 접촉편부(11)(11')가 도 4와 같이 백카바(1') 내면에 코팅된 피접지물이 되는 도전체(4)에 접촉된 상태가 되었을때에도 압축코일스프링(13)이 항시 접촉편부(11)(11')를 내측으로 당기게 됨으로써 이들이 도전체(4)에 더욱 밀착되는 상태로 접촉된다.In addition, even when the contact piece 11, 11 'is brought into contact with the conductor 4 to be the grounded object coated on the inner surface of the back cover 1' as shown in Fig. 4, the compression coil spring 13 The contact pieces 11 and 11 'are always pulled inward so that they are brought into close contact with the conductor 4.

즉, 금속재질의 어스플레이트(10) 접촉편부(11)(11')가 회복력이 약해서 도전체(4)와 밀착되지 않게 된 것을 본 고안에 의해서 접촉편부(11)(11')가 도전체(4)에 접촉되는 밀착력을 더욱 좋게 하는 것이다.That is, according to the present invention, the contact piece portions 11 and 11 'are made of a metallic material so that the contact pieces 11 and 11' of the metal plate 10 are not in close contact with the conductor 4 due to the weak recovery force. It is to improve the adhesive force in contact with (4).

이상의 설명에 따르면, 본 고안에 의해 피접지물에 접촉되는 어스플레이트의 접촉편부가 밀착력이 좋아지므로 그라운드 효과의 향상이 도모된다.According to the above description, since the contact part of the earth plate which contacts the to-be-ground object by this invention improves adhesive force, the ground effect is improved.

그리고 취급 부주의에 의한 어스플레이트의 접촉편부 변형이 초래되어도 압축코일스프링의 탄력에 의해 원래대로 복귀되므로 제품에서의 접지불량을 미연에 방지하는 효과를 갖는 유용한 고안이다.And even if the contact piece of the earth plate caused by careless handling is returned to the original by the elasticity of the compression coil spring, it is a useful design having the effect of preventing the ground failure in the product in advance.
