Description

모니터용 브라운관의 접지 장치 {Device for grounding the brawn tube of monitor}Device for grounding the brawn tube of monitor}

본 발명은 모니터용 메인섀시의 전방플랜지부에 설치되어 브라운관을 접지하여주는 접지스프링에 관한 것으로, 특히 접지스프링의 구조를 변경하여 메인섀시로 분해/조립하는 조립공수 및 작업하중을 절감시킬 수 있도록 된 모니터용 브라운관의 접지 장치에 관한 것이다.The present invention relates to a ground spring which is installed in the front flange of the main chassis for the monitor to ground the CRT, in particular to change the structure of the ground spring to reduce the assembly labor and work load to disassemble / assemble into the main chassis. It relates to a grounding device of a CRT for a monitor.

일반적으로, 모니터는 전방커버와 후방커버가 상호 결합되어 그 외관을 이루게 되는 함체로서, 그 내부공간에 각종 회로기판을 보호하여주는 메인섀시(main chassis)이 수평방향으로 장착되면서, 이 메인섀시의 상부측에 화면을 재생하여주는 브라운관이 설치되어 있다.In general, the monitor is a housing in which the front cover and the rear cover are coupled to each other to form an external appearance, and a main chassis for protecting various circuit boards is mounted in a horizontal direction in the interior space thereof. The CRT is installed on the upper side to reproduce the screen.

그리고, 모니터용 메인섀시의 전방측을 이루는 플랜지부에 브라운관을 접지하여 각종 전장품을 보호하여주는 한 개이상의 접지스프링(groung spring)이 설치되어, 필요에 따라 분해조립할 수 있도록 되어 있다.In addition, one or more ground springs (groung springs) are installed on the flanges forming the front side of the main chassis for the monitor to protect various electric appliances, so that they can be disassembled and assembled as necessary.

즉, 모니터에는 도 1에 도시된 바와 같이, 전방커버(100)의 내벽에 그 전방플랜지부를 따라 한 개이상의 체결공(111)이 형성되어진 메인섀시(110)가 수평방향으로 장착되되, 메인섀시(110)의 체결공(111)에 보울트(120)와 같은 체결수단을 매개로 브라운관을 접지하여주는 접지스프링(130)이 장착되어 있다.That is, as shown in FIG. 1, the main chassis 110 having one or more fastening holes 111 formed on the inner wall of the front cover 100 along the front flange is mounted in a horizontal direction. A ground spring 130 is provided to ground the CRT through the fastening means such as the bolt 120 in the fastening hole 111 of the chassis 110.

따라서, 메인섀시(110)의 전방플랜지부에 형성되어진 체결공(111)에 접지시프링(130)의 보울트공(131)을 맞댄 상태에서 보울트(120)체결하면, 메인섀시(110)의 전방플랜지부에 접지스프링(130)이 고정됨은 물론, 이 접지스프링(130)을 인해 메인섀시(110)의 상부측으로 위치되는 브라운관이 접지되는 것이다.Therefore, when the bolt 120 is fastened to the fastening hole 111 formed in the front flange portion of the main chassis 110 in a state where the bolt hole 131 of the ground shift ring 130 is fastened, the front of the main chassis 110 is closed. As well as the ground spring 130 is fixed to the flange portion, the ground tube 130 is grounded due to the ground tube 130 to the upper side of the main chassis 110.

그런데, 메인섀시(110)의 전방플랜지부에 접지스프링(130)을 고정시키기 위해서는, 작업자가 일일이 보울트(120)를 체결해야하므로 작업하중이 증대됨은 물론 작업성이 저하될 뿐만 아니라, 메인섀시(110)에 단지 한개의 보울트(120)에 의해 접지스프링(130)이 고정되므로, 보울트(120)를 중심점으로 접지스프링(130)이 회전되어, 브라운관의 접지기능이 저하되는 문제점이 있었다.However, in order to fix the ground spring 130 to the front flange portion of the main chassis 110, since the worker must fasten the bolt 120 one by one, not only the work load is increased but also the workability is reduced, and the main chassis ( Since the ground spring 130 is fixed by only one bolt 120 to 110, the ground spring 130 is rotated around the bolt 120, thereby degrading the grounding function of the CRT.

한편, 메인섀시(110)의 전방플랜지부에 코킹과 같은 접합수단으로 접지스프링(130)을 고정시키는 방법이 제안되어 있기는 하지만, 접지스프링(130)이 코킹으로 접합되는 경우 실질적으로 분해조립이 불가능한 불편함이 있음은 물론, 코킹이 원하는데로 이루어지지 않아 분리되는 경우 브라운관의 접지기능이 실질적으로 이루어지지 않는 문제점이 있었다.Meanwhile, although a method of fixing the ground spring 130 to the front flange portion of the main chassis 110 by a joining means such as caulking has been proposed, when the ground spring 130 is joined by caulking, disassembly and assembly may be substantially performed. Of course, there is a problem that the grounding function of the CRT is not substantially made when the separation is not made as desired, as well as the uncomfortable inconvenience.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위하여 안출된 것으로서, 메인섀시의 전방플랜지부에 접지스프링의 분해조립과정을 원티치식으로 이루어지게 함은 물론 접지스프링의 고정력을 증대되게하여 브라운관의 접지기능을 극대화시킬 수 있도록 된 모니터용 브라운관의 접지 장치를 제공하는 데에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the problems as described above, to make the disassembly assembly process of the ground spring in the front flange portion of the main chassis in a one-inch manner, as well as to increase the fixing force of the ground spring. The purpose of the present invention is to provide a grounding device for the CRT monitor, which can maximize the CRT grounding function.

상기한 바의 목적을 달성하기 위한 본 발명은, 전방커버의 내벽에 수평방향으로 장착되어진 메인섀시의 전방플랜지부를 따라 브라운관의 접지하여주는 접지스프링을 고정하여주기 위한 모니터용 브라운관의 고정장치를 구성함에 있어서, 메인섀시를 이루는 전방플랜지부의 전방면에 최소한 한 개이상의 걸쇠가 양측으로 나란하게 형성되며, 접지스프링의 몸체에 걸쇠의 걸림홈을 향해 상부측에서 하부측으로 끼워져 고정되는 절개후크가 일체로 형성되어 있다.The present invention for achieving the object of the above bar, the fixing device of the monitor CRT for fixing the ground spring for grounding the CRT along the front flange of the main chassis mounted horizontally on the inner wall of the front cover In the configuration, at least one latch is formed on both sides of the front flange of the front flange forming the main chassis side by side, and the incision hook is fixed from the upper side to the lower side toward the locking groove of the clasp on the ground spring body. It is formed integrally.

In configuring the fixing device of the monitor CRT for fixing the ground spring 130 for grounding the CRT, at least one clasp on the front surface of the front flange 10 forming the main chassis 110. (20) is formed side by side on both sides, the body of the ground spring 130 to the locking groove 21 of the clasp 20 is inserted into the structure from the upper side to the lower side fixed to the cutting hook 30 is formed integrally It is.

먼저, 본 발명에 따른 구성요소 중 모니터의 전방커버(100)와 이 전방커버의 내벽하부측으로 결합되는 메인섀시(110)와 이 메인섀시의 전방플랜지부로 고정되는 접지스프링(130)은 종래기술과 기능상 동일하므로 여기서는 자세한 설명은 생략하기로 하고, 다만 메인섀시(110)의 전방플랜지부(10)와 접지스프링(130)의 형상이 변경된 것에만 그 차이점이 있음을 첨언한다.First, among the components according to the present invention, the front cover 100 of the monitor and the main chassis 110 coupled to the inner wall lower side of the front cover and the ground spring 130 fixed to the front flange of the main chassis are related art. And since the functional description is the same and a detailed description will be omitted here, but adds that there is a difference only in the shape of the front flange 10 and the ground spring 130 of the main chassis 110 is changed.

그리고, 걸쇠(20)는, 메인섀시(110)의 전방측을 이루는 전방플랜지부(10)의 전방면에 장착되어지는 한 개이상의 고리부재로서, 전방플랜지부(10)의 전방면에 수평방향을 따라 장착된 상태에서, 그 하우징의 중심부에 상하방향을 따라 걸림홈 (21)이 관통형성되어 있다.In addition, the clasp 20 is one or more ring members mounted on the front surface of the front flange portion 10 forming the front side of the main chassis 110, the horizontal direction on the front surface of the front flange portion 10 In the attached state, the engaging groove 21 is formed in the center of the housing along the vertical direction.

그리고, 절개후크(30)는, 접지스프링(130)의 몸체를 대략 "∪"자로 절개하여 상하방향으로 형성시킨 걸림부재로서, 걸쇠(20)의 설치위치와 대응하는 위치 및 걸쇠(20)의 걸림홈(21)과 대응하는 크기로 형성되어 있다.In addition, the cutting hook 30 is a locking member formed by cutting the body of the ground spring 130 in an approximately "∪" shape and formed in the up and down direction, and the position corresponding to the installation position of the clasp 20 and the clasp 20. It is formed in the size corresponding to the locking groove 21.

이하, 본 발명에 따른 작용을 첨부된 예시도면을 참고로하여 상세하게 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings illustrating the operation according to the present invention.

먼저, 본 발명에 따른 모니터용 전방커버(100)에 메인섀시(110)를 장착하기 위해서는, 일단 메인섀시(110)의 전방플랜지부(10)에 접지스프링(130)을 설치하여 고정시키는 작업과정이 선결되어야함을 첨언한다.First, in order to mount the main chassis 110 to the front cover 100 for the monitor according to the present invention, the work process of installing and fixing the ground spring 130 to the front flange portion 10 of the main chassis 110 once It is to be noted that this must be made in advance.

즉, 접지스프링(130)의 몸체를 손이나 공구로 잡고, 접지스프링(130)의 절개후크(30)를 걸쇠(20)의 걸림홈(21)으로 맞댄 상태에서, 상부측방향에서 하부측방향으로 향하면서 가볍게 밀어넣는다.That is, while holding the body of the ground spring 130 with a hand or a tool, the cutting hook 30 of the ground spring 130 with the engaging groove 21 of the clasp 20, in the upper side to the lower side direction Gently push in toward.

이렇게 하면, 접지스프링(130)의 절개후크(30)의 탄성력이 걸쇠(20)의 걸림홈(21)의 내부공간에서 밀착되는 상태이므로, 절개후크(30)가 걸림홈(21)으로 삽입된 상태에서는 유격의 발생을 방지시킨다.In this case, since the elastic force of the cutting hook 30 of the ground spring 130 is in close contact with the inner space of the locking groove 21 of the clasp 20, the cutting hook 30 is inserted into the locking groove 21. The state prevents the occurrence of play.

물론, 접지스프링(130)의 절개후크(30)가 걸림홈(21)의 상부측에서 하부측으로 삽입된 상태이므로, 예컨대, 메인섀시(110)의 상부측에 브라운관이 위치되는 경우에도, 브라운관의 자중에 의한 접지스프링(130)의 이탈이 방지되는 것이다.Of course, since the cutting hook 30 of the ground spring 130 is inserted from the upper side to the lower side of the catching groove 21, for example, even when the CRT is located on the upper side of the main chassis 110, Leaving of the ground spring 130 by its own weight is prevented.

그런 다음, 전방커버(100)의 설치위치에 접지스프링(130)이 구비된 메인섀시 (130)를 고정시키고 전방커버(100)의 설치위치로 브라운관을 고정시키면, 메인섀시와 브라운관의 사이에 접지스프링이 개재되어 접지기능을 수행하게 된다.Then, when the main chassis 130 having the ground spring 130 is fixed to the installation position of the front cover 100 and the CRT is fixed to the installation position of the front cover 100, the ground between the main chassis and the CRT The spring is interposed to perform the grounding function.

한편, 접지스프링(130)이 손상되었거나 교환하고자 하는 경우에, 접지스프링 (130)의 몸체를 손이나 공구로 잡고 상부측방향으로 향해 가볍게 잡아당기면, 접지스프링(130)이 인출이 이루어진다.On the other hand, when the ground spring 130 is damaged or to be replaced, by holding the body of the ground spring 130 with a hand or a tool and gently pulled toward the upper side, the ground spring 130 is drawn out.

즉, 걸쇠(20)의 걸림홈(21)에 절개호크(30)를 통해 꽉 끼여진 상태로 고정되어 있던 접지스프링(130)이 외력(손이나 공구)에 의해 이탈되는 상태이므로, 작은 힘으로도 접지스프링(130)의 분해가 가능해지는 것이다.That is, since the ground spring 130, which is fixed in the clamping groove 21 of the latch 20 through the cutting hawk 30, is separated by external force (hand or tool), In addition, the ground spring 130 can be disassembled.

이상에서 설명한 바와 같이 본 발명에 따른 모니터용 브라운관의 접지 장치에 의하면, 모니터용 메인섀시에 접지스프링이 원터치식으로 고정/분해되므로 접지스프링의 분해/조립에 따른 작업하중이 절감되어 작업성이 향상될 뿐만 아니라, 접지스프링이 고정된 상태에서 유동발생이 최소화되므로 브라운관의 접지기능이 향상되어 전장품의 수명이 연장되는 효과가 있는 것이다.As described above, according to the grounding apparatus of the CRT for monitor according to the present invention, since the ground spring is fixed / disassembled in the main chassis for the monitor by one touch, the work load due to the disassembly / assembly of the ground spring is reduced and workability is improved. In addition, since the occurrence of flow is minimized in the state that the ground spring is fixed, the grounding function of the CRT is improved, which has the effect of extending the life of the electronic device.
