본 고안은 튜너를 TV이나 VTR의 인쇄회로기판(PCB)에 장착시키는 튜너 결합장치에 관한 것으로, 특히 튜너샤시에 지지부를 형성하여 튜너를 보다 견고하게 결합시킬수 있도록 한 튜너 결합장치에 관한 것이다.The present invention relates to a tuner coupling device for mounting a tuner on a printed circuit board (PCB) of a TV or a VTR, and more particularly, to a tuner coupling device that allows the tuner to be more firmly coupled by forming a support on the tuner chassis.
일반적으로 튜너는 TV이나 VTR에 설치되어 RF신호를 인가하는 것으로서, 이는 튜너를 TV이나 VTR에 장착시킬때 원가를 절감시키기 위하여 브라트를 이용하지 않고 TV의 메인기판이나 셀랙터 보오드 기판에다 직접 삽입장착시키고 있다. 그런데 상기와 같은 방법은 인쇄회로기판에 튜너가 직접 장착됨으로 말미암아 튜너의 중량이나 그 위치에 따라 드롭시험(Drop test)에서 불량이 발생하는 문제점이 야기되고 있는바, 이러한 현상을 특히 튜너샤시가 제4도와 같이 전후면 방향으로 취약한 구조로 형성되어 있어 더욱 커지게 되는 것이다.In general, a tuner is installed in a TV or VTR to apply an RF signal, which is directly inserted into the main board or selector board of the TV without using a bracket to reduce cost when the tuner is mounted on the TV or VTR. I put it on. However, the above-described method causes a problem in that a defect occurs in the drop test due to the tuner's weight or its position directly mounted on the printed circuit board. As shown in Figure 4 is formed in a weak structure in the front and rear direction will become larger.
이에 본 고안에서는 상기와 같은 종래의 문제점을 해결하기 위하여 튜너샤시의 결합부에다 솔더링돌기를 형성시키고, 솔더링돌기와 연하여 지지부를 형성시키되 지지부를 인쇄회로기판과 면접촉되도록 형성하여 세트의 드롭테스트 및 충격테스트에 의한 불량을 감소시키며, 인쇄회로기판의 크랙을 방지할 수 있도록 한 튜너결합장치를 제공하는데 그 목적이 있다.Therefore, in the present invention, in order to solve the above-mentioned problems, a soldering protrusion is formed on the coupling portion of the tuner chassis, and the support portion is formed by connecting with the soldering protrusion, but the support portion is formed to be in surface contact with the printed circuit board. An object of the present invention is to provide a tuner coupling device that reduces defects caused by impact tests and prevents cracks in printed circuit boards.
이하 본 고안의 구성 및 작용효과를 첨부된 예시도면에 의거 상세히 설명하면 다음과 같다.Hereinafter will be described in detail based on the accompanying drawings and the configuration and effect of the present invention.
본 고안은 튜너샤시(1)의 결합부(2)에 인쇄회로기판(3)과 결합되도록 솔더링돌기(4)를 형성시키고, 상기 솔더링돌기(4)와 연하여 지지부(5)를 형성시키되, 지지부(5)를 상기 인쇄회로기판(3)과 면접촉되도록 직각으로 형성시킨 구조로 되어 있다.According to the present invention, the soldering protrusion 4 is formed on the coupling portion 2 of the tuner chassis 1 so as to be coupled to the printed circuit board 3, and the support portion 5 is formed in connection with the soldering protrusion 4. The support 5 is formed at right angles to be in surface contact with the printed circuit board 3.
미설명부호 6은 투너이다.Reference numeral 6 is a tuner.
상기와 같은 구조로된 본 고안은 지지력이 취약한 종래 튜너샤시의 구조를 변경하여 지지력을 보완한 것이며, 제1도는 본 고안의 사시도로서 튜너샤시(1)의 결합부(2)에 솔더링돌기(4)를 형성시켜 인쇄회로기판(3)과 결하보디도록 한 것이고, 또한 솔더링돌기(4)와 연하여는 튜너(6)가 인쇄회로기판(3)에 견고하게 밀착결합되도록 지지부(5)를 형성하였는데 지지부(5)는 튜너(6)의 외부방향으로 90°정도 꺽어 인쇄회로기판(3)에 면접촉되도록 한 것이다.The present invention having the structure as described above is to supplement the bearing capacity by changing the structure of the conventional tuner chassis weak bearing capacity, Figure 1 is a perspective view of the subject innovation soldering projections (4) to the coupling portion (2) of the tuner chassis (1) ) Is formed to bond with the printed circuit board (3), and in addition to the soldering protrusion (4), the support (5) is formed so that the tuner (6) is tightly coupled to the printed circuit board (3). The support part 5 is to be brought into surface contact with the printed circuit board 3 by bending 90 ° to the outside of the tuner 6.
또한, 제2도는 본 고안의 요부확대사시도로서 본 고안의 요부를 보다 정확히 나타내고 있는데, 솔더링돌기(4)와 연하여 튜너(6)의 외부방향으로 형성된 지지부(5)는 솔더링돌기(4)의 양 외측에 형성한 것이고, 튜너샤시(1)의 폭을 감안하여 지지부(5)를 솔더링돌기(4)의 양내측에 형성할 수 도 있다.2 is an enlarged perspective view of the main part of the present invention, which shows the main part of the present invention more accurately. The support part 5 formed in the outward direction of the tuner 6 in connection with the soldering protrusion 4 is formed of the soldering protrusion 4. It is formed on both sides, and the support part 5 can also be formed in the both inner side of the soldering protrusion 4 in consideration of the width | variety of the tuner chassis 1.
한편, 제3도는 본 고안의 결합단면도로서, 제4도와 같이 솔더링돌기(4)가 인쇄회로기판(3)을 관통하여 솔더링돌기(4)에 의해서만 지지되던 종래의 방법을 개선하여 솔더링돌기(4) 뿐만 아니라 지지부(5)에 의해서도 면접촉되어 튜너(6)가 인쇄회로기판(3)에 지지되도록 한 것이다.On the other hand, Figure 3 is a cross-sectional view of the present invention, as shown in Figure 4 to improve the conventional method that the soldering protrusion 4 is supported only by the soldering protrusion 4 through the printed circuit board 3, the soldering protrusion 4 As well as the surface contact by the support (5) is to allow the tuner 6 to be supported by the printed circuit board (3).
이와 같은 본 고안은 인쇄회로기판(3)과 결합되는 솔더링돌기(4)에 연해서 지지부(5)를 형성하므로서 튜너(6)의 결합력이 증가할 뿐만 아니라 드롭테니트 및 충격테스트에 의한 불량이 감소되는 효과가 있다.The present invention is not only increases the coupling force of the tuner 6 but also reduces the defects caused by drop tennis and impact test by forming the support part 5 in contact with the soldering protrusion 4 coupled to the printed circuit board 3. It is effective.
