본 고안은 튜너샤시와 메인 PCB와의 조립고정구조에 관한 것으로 이는 특히, 튜너샤시의 다리부측으로 서로 일정거리 이격되어 대향하는 하향 경사단편과 상향 경사단편을 돌설하여 PCB의 장방홀내에 삽입 고정토록 함으로써, 튜너샤시의 다리부 고정 설치 작업이 용이하고, 상기 튜너샤시가 PCB상에 견고하게 고정될 수 있도록 한 조립 고정구조에 관한 것이다.The present invention relates to an assembly fixing structure between a tuner chassis and a main PCB. In particular, the inclined downward fragment and the upward inclined fragment are spaced apart from each other by a predetermined distance to the leg side of the tuner chassis, so that they are inserted into and fixed in the rectangular hole of the PCB. In addition, the leg fixing of the tuner chassis installation work is easy, and relates to an assembly fixing structure that allows the tuner chassis to be firmly fixed on the PCB.
일반적으로 알려져 있는 튜너샤시와 메인 PCB의 조립고정 구조에 있어서는 제1도 내지 제3도에 도시한 바와 같이, 튜너샤시(1) 측변다리(11)에는 그 소정부위의 상부에서부터 하부로 하향하는 경사단편(11a)과 비딩(11b)을 돌출 형성하고, 메인 PCB(2)측에는 복수의 장방홀(21)을 형성한 구조로 이루어졌다.In general, in the assembly fixing structure of the tuner chassis and the main PCB, as shown in FIGS. 1 to 3, the tuner chassis 1 side leg 11 is inclined downward from the upper part of the predetermined part. The fragment 11a and the bead 11b were formed to protrude, and a plurality of rectangular holes 21 were formed on the main PCB 2 side.
그리고, 여기서는 튜너샤시(1)의 다리를 PCB(2)측의 장방홀(21)로 밀어넣어 PCB(2)를 관통한 다리가 이면측의 동박면(2a)을 가로질러 위치되고 이에 납땜 처리하게 되는 것이다.Here, the leg of the tuner chassis 1 is pushed into the rectangular hole 21 on the side of the PCB 2 so that the leg penetrating the PCB 2 is positioned across the copper foil surface 2a on the back side and soldered thereto. Will be done.
또한, 상기 튜너샤시(1)측에 경사단편(11a)이나 비딩(11b)이 존재하지 않을 경우에는, 튜너샤시(1)가 PCB(2)면에서 들뜨거나 한쪽 방향으로 기울어진 상태에서 납땜 처리되는 경향이 많으므로 일반적으로 상기예의 구조를 형성시키고 있다.In addition, when the inclined piece 11a or the bead 11b does not exist in the tuner chassis 1 side, soldering process is carried out in the state in which the tuner chassis 1 is lifted from the PCB 2 surface or inclined in one direction. Since there is much tendency to become, generally the structure of the said example is formed.
그러나, 이러한 구성에 있어서는 튜너샤시(1)의 측변두께를 벗어난 비딩(11b)이 PCB(2)측 장방홀(21)로 진입될 때, 이 장방홀(21)에 상기 비딩(11b)이 걸리기 때문에 무리한 힘을 가하여 조립하게 되고, 조립이 완료되었을 경우에도 제3도에 도시한 바와 같이 튜너샤시가 PCB에 불완전하게 결합되는 것이다.However, in this configuration, when the bead 11b outside the side thickness of the tuner chassis 1 enters the rectangular hole 21 on the PCB 2 side, the bead 11b is caught in the rectangular hole 21. Because of the excessive force to assemble, even when the assembly is completed, as shown in Figure 3 the tuner chassis is incompletely coupled to the PCB.
또한, 무리한 힘을 가하여 비딩(11b)을 PCB의 장방홀(21)에 삽통시키는 과정에서는 장방홀(21)측의 크랙발생 및 동박면, 패턴부에 손상이 빈번하게 발생되며, PCB(2)위에 기타 조립부품들의 다리가 빠져 이탈되는 등 많은 문제점이 있었던 것이다.In addition, in the process of inserting the bead 11b into the rectangular hole 21 of the PCB by applying excessive force, cracks and copper foil on the rectangular hole 21 side, and damage to the pattern portion frequently occur, the PCB (2) There were many problems, such as falling off the legs of the other assembly parts.
본 고안은 상기한 바와 같은 종래의 제반 문제점들을 개선시키기 위하여 안출된 것으로서 그 목적은, 튜너샤시의 다리부측으로 서로 일정거리 이격되어 대향하는 하향 경사단편과 상향 경사단편을 각각 설치하여 PCB의 장방홀내에 삽입 고정토록 함으로써, 튜너 샤시의 다리부를 PCB상에 조립 설치가 용이하며, 상기 튜너샤시가 PCB상에 견고하게 고정될 수 있는 튜너샤시와 메인 PCB와의 조립 고정 구조를 제공하는데 있다.The present invention has been made in order to improve the conventional problems as described above, the purpose is to install the lower inclined fragment and the upper inclined fragment facing each other at a predetermined distance to the leg side of the tuner chassis, respectively, the rectangular hole of the PCB By inserting and fixing in the inside, it is easy to assemble and install the leg portion of the tuner chassis on the PCB, and to provide an assembly fixing structure between the tuner chassis and the main PCB which can be firmly fixed on the PCB.
이하, 첨부된 도면을 기초하여 본 고안을 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제4도는 본 고안의 튜너샤시측의 요부 구조도이고, 제5도는 본 고안에 의한 조립 고정상태를 도시한 참고도로서, 튜너샤시(1)의 양측단리부에 요설된 홀(a)을 기준으로 양측에 각각 하향 경사단편(11a)과 상향 경사단편(11c)이 서로 PCB의 두께만큼 일정거리 이격되어 대향설치되어, PCB(2)의 장방홀(21)내에 삽입 고정토록 되는 구성으로 이루어진다.4 is a structural diagram of the main portion of the tuner chassis side of the present invention, Figure 5 is a reference diagram showing the assembly fixed state according to the present invention, based on the hole (a) concave on both sides of the tuner chassis (1) The downwardly inclined fragments 11a and the upwardly inclined fragments 11c are respectively installed on both sides to be spaced apart by a predetermined distance from each other by the thickness of the PCB so as to be inserted into and fixed in the rectangular hole 21 of the PCB 2.
이와 같은 구조로 이루어진 본 고안은 튜너샤시와 메인 PCB의 조립 고정 구조는, 제4도 및 제5도에 도시한 바와 같이, 튜너샤시(1)의 다리부가 PCB(2)측 장방홀(21)로 각기 진입되어질땐 상향 경사단편(11c)의 경사면을 타고 원활히 장방홀(21)로 진입되어지고, 하향경사단편(11a)에 의해 튜너샤시(1)의 다리부는 PCB(2)의 장방홀(21) 상에 걸려서 고정토록 되어 제5도에서와 같이 견고하게 결합 고정토록 되는 것이다.According to the present invention having such a structure, the assembly structure of the tuner chassis and the main PCB is as shown in FIGS. 4 and 5, and the leg portion of the tuner chassis 1 has a rectangular hole 21 on the PCB 2 side. In each case, the inclined surface of the inclined chassis 11 is smoothly entered into the rectangular hole 21 by the inclined surface of the upward inclined fragment 11c, and the leg portion of the tuner chassis 1 is inclined into the rectangular hole of the PCB 2 by the downward inclined fragment 11a. 21) to be fixed on the hook to be firmly fixed as shown in FIG.
상술한 바와 같이 본 고안에 의한 튜너샤시와 메인 PCB와의 조립 고정 구조에 의하면, PCB의 장방홀에 내삽 고정토록 되는 튜너샤시의 다리부 구조를 상기와 같이 개선함으로써, 튜너샤시를 PCB상에 조립설치가 용이하며, 특히 상기 튜너 샤시가 PCB상에 견고하게 고정 설치될 수 있는 우수한 효과가 있다.As described above, according to the assembly fixing structure of the tuner chassis and the main PCB according to the present invention, the tuner chassis is assembled and installed on the PCB by improving the leg structure of the tuner chassis that is interpolated and fixed in the rectangular hole of the PCB as described above. It is easy, and in particular, the tuner chassis has an excellent effect that can be firmly installed on the PCB.
