Description
본 고안은 TV 및 모니터 등의 영상장치에 고압을 인가하는 플라이백 트랜스포머의 결합 구조에 관한 것으로, 더욱 상세하게는 인쇄회로기판에 결합되는 플라이백 트랜스포머 체결부의 강도를 개선하여 플라이백 트랜스포머와 인쇄회로기판의 결합구조에 관한 것이다.The present invention relates to a coupling structure of a flyback transformer applying high pressure to an image device such as a TV and a monitor. More specifically, the flyback transformer and the printed circuit are improved by improving the strength of the flyback transformer coupling part coupled to the printed circuit board. It relates to a bonding structure of the substrate.
종래의 플라이백 트랜스포머와 인쇄회기판의 결합구조를 살펴보면 다음과 같다.Looking at the coupling structure of the conventional flyback transformer and the printed circuit board as follows.
상기 플라이백 트랜스포머 하우징 외주연 하부에 체결부의 수직편이 탄성력을 갖고 플라이백 트랜스포머 하우징과 일정한 간격을 유지하면서 하향으로 형성되어 있다.A vertical piece of the fastening part is formed downward in the lower portion of the flyback transformer housing and has an elastic force and maintains a constant distance from the flyback transformer housing.
상기 하향으로 형성된 수직편의 하단에는 걸림턱이 형성되어 있다.A locking step is formed at a lower end of the vertical piece formed downward.
상기 걸림턱과 대향되는 인쇄회로기판에 걸림공을 형성하여 플라이백 트랜스포머 하우징이 인쇄회로기판에 결합되게 하였다.A catching hole is formed in the printed circuit board opposite to the catching jaw so that the flyback transformer housing is coupled to the printed circuit board.
그러나 이와같은 구성은 수직편이 플라이백 트랜스포머 하우징과 일정한 간격을 유지하여 하향으로 형성되어 있기 때문에 인쇄회로기판에 결합시 수직편에 응력이 발생되어 절곡된 부분에 크랙이 발생하게 되었다.However, in this configuration, since the vertical pieces are formed downwardly at regular intervals from the flyback transformer housing, stresses are generated on the vertical pieces when they are bonded to the printed circuit board, causing cracks in the bent portion.
여기서 응력은 물체가 외부로부터 힘을 받았을 때, 물체 안에 생기는 반작용의 힘 즉, 내력(內力) 왜력(歪力)을 말한다.Here, the stress refers to the reaction force generated in the object when the object is subjected to the force from the outside, that is, the internal force distortion.
상기 크랙으로 인하여 플라이백 트랜스포머 하우징이 인쇄회로 기판에 견고히 결합되지 못하였다.The crack prevented the flyback transformer housing from being firmly coupled to the printed circuit board.
또한 크랙으로 인하여 플라이백 트랜스포머의 움직임이 발생되어 음극선관에 고압을 인가하는 플라이백 트랜스포머의 기능을 발휘하지 못했다.In addition, the cracks caused the flyback transformer to move, which prevented the flyback transformer from applying high pressure to the cathode ray tube.
따라서, 본 고안은 종래의 문제점을 해결하고자, 플라이백 트랜스포머 하우징 체결부 크랙이 발생되지 않고 응력을 분산시킨 동시에 수직편이 가지고 있는 탄성력을 그대로 유지하여 인쇄회로기판에 견고하게 결합하도록 하는데 있다.Accordingly, the present invention is to solve the conventional problems, to ensure that the flyback transformer housing fastening part cracks are not generated, while maintaining the elastic force of the vertical piece as it is to maintain the elastic force as it is to be firmly coupled to the printed circuit board.
따라서, 본 고안은 종래의 문제점을 해결하기 위하여 플라이백 트랜스포머 하우징을 인쇄회로기판에 결합시 수직편에 발생하는 응력을 분산시키고 크랙이 발생하지 않도록 하는 플라이백 트랜스포머 결합 구조에 관한 것이다Accordingly, the present invention relates to a flyback transformer coupling structure for dispersing stress generated in the vertical pieces and preventing cracks from occurring when the flyback transformer housing is coupled to a printed circuit board in order to solve the conventional problems.
본 고안의 다른 목적은 수직편에 크랙을 방지하여 플라이백 트랜스포머를 인쇄회로기판에 결합시킬때 제품의 불량률을 최소화 하는데 있다.Another object of the present invention is to prevent cracks in the vertical piece to minimize the failure rate of the product when coupling the flyback transformer to the printed circuit board.
본 고안의 다른 목적은 플라이백 트랜스포머의 움직임을 최소화 하여 음극선관에 고전압을 정확하게 공급 하도록 하는 데 있다.Another object of the present invention is to minimize the movement of the flyback transformer to accurately supply high voltage to the cathode ray tube.

The flyback transformer housing 10 and the flyback transformer housing 10 have a locking hole 21 formed at a position opposite to the fastening portion 11 so as to pass through the locking jaw 13 and the locking hole 21. By constructing the printed circuit board 20 to which the back transformer housing 10 is coupled, cracks do not occur in the bent portion and the strength of the fastening portion 11 is improved.
또한 보강편(14)에 의하여 수직편(12)에 크랙이 발생하지 않기 때문에 플라이백 트랜스포머 하우징(10)와 인쇄회로기판 조립과정에서 제품의 불량 율이 대폭 감소됨과 동시에 제품의 신뢰성이 대폭 향상되는 효과가 있다.In addition, since cracks are not generated in the vertical piece 12 by the reinforcing piece 14, the defective rate of the product is greatly reduced during the assembly of the flyback transformer housing 10 and the printed circuit board, and the reliability of the product is greatly improved. It works.
