The member 10 is provided so that the movement in conjunction with the vertical movement. In addition, a stopper such as a predetermined bolt and washer may be installed at the upper end of the extension shaft 20 so that the extension shaft 20 is not separated from the support member 10 when the support member 10 is raised.

한편, 지지부재(10)의 홀(11)에 연장축(20)이 슬라이딩 가능하도록 설치됨으로써 연장축(20) 및 후술할 이동부재(30)의 하강운동이 멈추게 되더라도 지지부재(10)는 하강운동을 계속할 수 있게 된다.On the other hand, since the extension shaft 20 is installed in the hole 11 of the support member 10 to be slidable, even if the downward movement of the extension shaft 20 and the moving member 30 to be described later is stopped, the support member 10 is lowered. You can continue to exercise.

이동부재(30)는 연장축(20)의 바닥면과 결합하고 연장축(20)과 연동하여 상하로 운동하며 하강시 상기 프레임(60)의 스토퍼(80)의 상면과 맞닿도록 설치되어 있다. 또한, 연장축(20)과 결합하는 부분은 후술할 스프링(50)을 지지하도록 스프링지지부(30a)가 형성될 수 있다.The moving member 30 is coupled to the bottom surface of the extension shaft 20 and moves up and down in conjunction with the extension shaft 20 and is installed to contact the top surface of the stopper 80 of the frame 60 when descending. In addition, the portion coupled to the extension shaft 20 may be formed with a spring support (30a) to support the spring 50 to be described later.

가압부재(40)는 이동부재(30)의 바닥면에 설치되며, 상기 이동부재(20)가 하강시 램프체결부(80)의 좌우측 경사면(80a)(80b)을 양측으로 밀 수 있도록 돌출 형 성되어 있다.The pressing member 40 is installed on the bottom surface of the movable member 30, and protrudes so that the movable member 20 can push the left and right inclined surfaces 80a and 80b of the ramp fastening portion 80 to both sides when the movable member 20 descends. It is made.

이때, 가압부재(40)의 하부는 프레임(60)의 램프체결부(80)의 손상방지 및 램프체결부(70)의 좌우측 경사면(70a)(70b)을 양측으로 밀 때 그 미는 힘을 점진적으로 증가시키기 위해 타원형으로 형성될 수 있다. 이와 같이 형성됨으로써, 램프체결부(70)의 좌우측 경사면(70a)(70b)에 놓여지는 램프 리드의 하강 속도를 조절할 수 있어 램프의 손상을 줄일 수 있다.At this time, the lower portion of the pressing member 40 gradually prevents damage to the lamp fastening portion 80 of the frame 60 and gradually pushes the pushing force when the left and right inclined surfaces 70a and 70b of the lamp fastening portion 70 are pushed to both sides.

스프링(50)은 지지부재(10)의 바닥면과 이동부재(30)의 스프링지지부(30a)의 상면에 양단이 탄성적으로 지지되어 있다. 이와 같이 설치되어 스프링(50)은 지지부재(10)가 하강시 지지부재(10)와 스프링지지부(30a)에 의해 탄성압축되고, 지지부재(10) 상승시 탄성회복되어 이동부재(30)를 초기위치로 환원시킬 수 있다.Both ends of the spring 50 are elastically supported on the bottom surface of the support member 10 and the top surface of the spring support portion 30a of the movable member 30. Thus, the spring 50 is elastically compressed by the support member 10 and the spring support portion 30a when the support member 10 is lowered, and is elastically recovered when the support member 10 is raised to move the movable member 30. Can be reduced to the initial position.

본 발명에 따른 엘시디용 백라이트 유닛의 체결장치는 상술한 바와 같이 구성되어 높은 정확성 및 연속성을 갖춰 램프를 프레임에 결합시킬 수 있게 된다.The fastening device of the backlight unit for an LCD according to the present invention is configured as described above to be able to couple the lamp to the frame with high accuracy and continuity.

상술한 설명에 따라 본 발명에 따른 엘시디용 백라이트 유닛의 결합장치의 작동방법에 대해 설명한다. 도 5a 내지 도5d는 본 발명에 따른 엘시디용 백라이트 유닛의 결합장치의 작용도를 나타낸 것이다.According to the above description, a method of operating a coupling device of an LCD backlight unit according to the present invention will be described. 5a to 5d show the operation of the coupling device of the backlight unit for an LCD according to the present invention.

도 5a를 참조하면, 프레임(60)의 램프체결부(70)의 좌우측 경사면(70a)(70b)에 램프 리드(100b)가 놓여져 있고, 상향으로 본 발명에 따른 엘시디용 백라이트 유닛의 결합장치가 위치하고 있다. 이후, 도 5b에 도시된 바와 같이 지지부재(10)가 하강하면 이와 연동하는 가압부재(40)가 하강하여 램프체결부(70)의 좌우측 경 사면(70a)(70b)을 좌우 양측으로 밀게 되고, 램프체결부(70)의 좌우측 경사면(70a)(70b) 상부에 놓여져 있던 램프 리드(100b)는 하강하여 스토퍼(80)에 형성된 홈(80a)에 안착된다. Referring to Figure 5a, the lamp lead 100b is placed on the left and right inclined surfaces 70a and 70b of the lamp fastening portion 70 of the frame 60, the upward coupling device of the LED backlight unit according to the present invention Is located. Subsequently, as shown in FIG. 5B, when the supporting member 10 descends, the pressure member 40 interlocking with the lowering member 10 descends to push the left and right inclined surfaces 70a and 70b of the lamp fastening portion 70 to both left and right sides. The lamp lead 100b, which is placed on the left and right inclined surfaces 70a and 70b of the lamp fastening portion 70, descends and is seated in the groove 80a formed in the stopper 80.

한편, 가압부재(40)가 램프체결부(70)의 좌우측 경사면(70a)(70b)을 좌우 양측으로 밀 수 있도록 가압부재(40)의 높이만큼 지지부재(10)의 하강운동을 제어하는 것이 매우 어렵기 때문에,도 5c에 도시된 것처럼 이동부재(30)는 바닥면이 스토퍼(80)의 상면과 맞닿게 되어 이동부재(30)의 하강운동은 멈추게 되지만, 지지부재(10)는 구동모터에 의해 계속 하강운동을 하게 된다.On the other hand, it is to control the downward movement of the support member 10 by the height of the pressing member 40 so that the pressing member 40 can push the left and right inclined surfaces 70a and 70b of the lamp fastening portion 70 to both left and right sides. Since it is very difficult, as shown in Figure 5c the movable member 30 is in contact with the top surface of the stopper 80, the lowering movement of the movable member 30 is stopped, but the support member 10 is a drive motor Will continue to descend.

이와 같은 지지부재(10)의 하강운동은 프레임(60)에 악영향을 줄 수 있으므로, 연장축(20)이 지지부재(10)의 홀(11)에 슬라이딩 가능하도록 설치됨으로써 이동부재(30)가 하강운동을 멈춘 후 지지부재(10)가 구동력을 계속 받아 하강하더라도, 연장축(20) 및 이동부재(30)는 지지부재(10)와 연동하여 하강하지 않게 되고, 지지부재(10)는 연장축(20)을 따라 슬라이딩하여 하강하게 된다.Since the downward movement of the support member 10 may adversely affect the frame 60, the movable member 30 is installed by the extension shaft 20 to be slidable in the hole 11 of the support member 10. Even if the support member 10 continues to descend after receiving the driving force, the extension shaft 20 and the movable member 30 do not descend in conjunction with the support member 10, and the support member 10 extends. It slides along the axis 20 and descends.

이때, 지지부재(10)는 스프링(50)을 탄성압축시키게 되고, 이후 도 5d에 도시된 바와 같이, 지지부재(10)가 상승하게 되면, 램프체결부(70)에 램프 리드(100b)는 결합되고 이동부재(30)는 스프링(50)에 의해 탄성복원되어 초기위치로 환원되게 된다.At this time, the support member 10 is to elastically compress the spring 50, and then as shown in Figure 5d, when the support member 10 is raised, the lamp lead (100b) to the lamp fastening portion 70 Coupled and the moving member 30 is elastically restored by the spring 50 is reduced to the initial position.
