본 고안의 튜너의 샤시에 그라운드 쉴드를 고정, 결합시키는 튜너의 그라운드 쉴드 고정 장치에 관한 것으로, 특히 샤시에는 걸림구멍과 결합구멍을, 그라운드 쉴드에는 걸림돌기와 결합턱을 각각 형성시킨 튜너의 그라운드 쉴드 고정장치에 관한 것이다.The present invention relates to a ground shield fixing device of a tuner that fixes and couples a ground shield to a chassis of the tuner of the present invention, and in particular, to a ground shield of a tuner in which a locking hole and a coupling hole are formed in the chassis, and a locking protrusion and a coupling jaw are respectively formed in the chassis. Relates to a device.

일반적으로 소형 튜너는 금속 샤시에 인쇄회로 기판을 끼우고 그라운드 쉴드를 그 위에 고정 결합시킨 다음 튜너를 뒤집어서 각 회로 소자를 인쇄회로 기판에 설치하고 솔더링 용액에 담가 솔더링을 행함으로써 제작되는데, 이때 튜너를 뒤집는 과정에서 그라운드 쉴드가 이탈되지 않도록 양호한 고정 결합이 요구되어 진다.Typically, small tuners are fabricated by inserting a printed circuit board into a metal chassis, fixing the ground shield on it, and then turning the tuner upside down to install each circuit element on the printed circuit board and soaking it in a soldering solution. Good fixation is required so that the ground shield does not escape during the reversal.

종래에는 샤시에 그라운드 쉴드를 고정시키는 경구 제4a도와 같이 샤시의 각면에 다홈을 형성시키고 그라운드 쉴드에다 상기 홈과 접촉 결합되도록 돌기를 형성시킨 엠보싱 결합을 사용해 왔으나, 이러한 방법은 고도의 정밀한 금형기술을 요구하게 되어 약간의 오차에도 결합이 불완전 하여 이탈되기가 쉽고, 수공으로 이루어져야 하는 그라운드 쉴드의 결합 작업시에는 4면을 모두 잘 맞춘다음 눌러서 결합하여야 하므로 작업시간이 지연되어지는 단점이 있었다.Conventionally, an embossed coupling has been used in which a multi-groove is formed on each side of the chassis and a protrusion is formed on the ground shield to be in contact with the groove, as shown in Fig. 4a, which fixes the ground shield to the chassis. However, this method uses highly precise mold technology. It is easy to be detached due to incomplete coupling due to some errors, and when joining the ground shield, which must be made by hand, all four sides must be well aligned and then pressed to combine, resulting in a delay in working time.

한편 상기와 같은 단점을 보완하는 방법으로서 제4b도와 같이 그라운드 쉴드에다 걸림돌기를 형성시키는 방법이 사용되었으나, 이러한 경우에도 역시 정밀한 금형기술이 요구되고, 또 샤시의 홈이 라운드져 있어 결합의 불완전을 완전히 보완하지 못하므로써 공정상의 불량발생률을 크게 줄이지 못하게 되어, 작업시간을 지연시키는 요인이 그대로 존재하는 상태였다.On the other hand, as a method for compensating the above disadvantages, a method of forming a protrusion on the ground shield is used as shown in FIG. 4b. However, in this case, precise mold technology is required, and the groove of the chassis is rounded to completely prevent incomplete coupling. By failing to compensate, it was not possible to greatly reduce the incidence of defects in the process, and the factor that delayed the working time was intact.

따라서 본 고안은 그라운드 쉴드의 일측면에는 걸림 돌기를 다른 면에는 결합턱을 각각 형성시키고, 샤시에는 상기 걸림돌기가 끼워질 걸림구멍과 상기결합턱이 결합될 결합구멍을 형성시킴으로써, 상기걸림돌기를 걸림구멍에 끼운 다음 가볍게 눌러주어 신속하게 결합할 수 있으며, 엠보싱 결합이나 걸림돌기에 의한 결합에 비해 결합 상태가 확실하고, 제작상 발생하는 오차에도 불구하고 뒤집을 때 이탈될 우려가 없을 뿐만 아니라 공정상의 불량발생률도 대폭 감소시킬 수 있는 튜너의 그라운드 쉴드 고정장치를 제공하는데 그 목적이 있는 것이다.Therefore, the present invention forms a locking projection on one side of the ground shield and a coupling projection on the other surface, respectively, and a locking hole on which the locking projection is fitted and a coupling hole on which the coupling projection is coupled, thereby catching the locking projection. It can be quickly combined by inserting it into the product, and then it can be quickly combined.The combination is more secure than the embossed or the locking projections, and there is no fear of falling off when flipping in spite of manufacturing errors. The purpose is to provide a ground shield fixture for the tuner that can be greatly reduced.

본 고안의 구성 및 작용효과를 예시된 도면에 의거 상세히 설명하면 다음과 같다.Referring to the configuration and operation of the present invention in detail based on the illustrated drawings as follows.

본 고안은 그라운드 쉴드(1)의 일측면에는 ㄱ자형의 걸림돌기(2)를 형성시키고 다른 면에는 외부로 구부러진 탄성을 가진 결합턱(3)을 형성시키며, 샤시(4)에는 상기 걸림돌기(2)가 끼워질 걸림구멍(5)과 상기 결합턱(3)이 결합될 결합구멍 (6)을 각각 형성시킨 구조로 되어 있다.The present invention forms an L-shaped locking protrusion 2 on one side of the ground shield 1, and forms a coupling jaw 3 having elasticity bent to the outside on the other side, and the locking protrusion (3) on the chassis 4 2) has a structure in which the engaging hole 5 into which the 2 is to be fitted and the engaging hole 6 to which the engaging jaw 3 is to be coupled are formed, respectively.

미설명부호 7은 인쇄회로 기판, 8, 9는 접지돌기이다.Reference numeral 7 denotes a printed circuit board, and 8 and 9 denote ground protrusions.

상기와 같은 구조에 있어서, ㄱ자형의 걸림돌기(2)는 외측으로 돌출되어 샤시(4)의 걸림구멍(5)에 끼워지며, 다른 측면에 형성시킨 결합턱(3)은 약간의 탄성을 가지고 외측으로 기울어져서 샤시(4)에 형성시킨 결합구멍(6)과 결합하여, 그라운드 쉴드(1)가 샤시(4)로부터 이탈되는 것을 막아준다.In the structure as described above, the L-shaped locking projection 2 is projected outward and fitted to the locking hole 5 of the chassis 4, and the engaging jaw 3 formed on the other side has a slight elasticity. Coupling with the engaging holes 6 formed in the chassis 4 by tilting outwards prevents the ground shield 1 from being separated from the chassis 4.

도면을 통해 상기 작용을 좀더 상세히 설명하면, 제1도는 샤시(4)와 인쇄회로 기판(7) 및 그라운드 쉴드(1)의 모습을 보여주는 본 고안의 분리사시도로써, 샤시(4)에는 인쇄회로 기판(7)에 형성시킨 접지구멍을 통해 돌출되는 접지돌기(8)와 걸림구멍(5) 및 결합구멍(6)을 형성시키고, 인쇄회로 기판(7)을 끼운 후에 고정 결합시키는 그라운드 쉴드(1)에는 상기접지돌기(8)와 접촉하게 될 접지돌기(9)와, 걸림돌기(2) 및 결합턱(3)을 형성시켰다.Referring to the above operation in more detail through the drawings, Figure 1 is a separate perspective view of the present invention showing the state of the chassis 4, the printed circuit board 7 and the ground shield (1), the chassis 4 has a printed circuit board A ground shield (1) for forming a ground protrusion (8), a locking hole (5), and a coupling hole (6) which protrude through the ground hole formed in the (7), and then fixing and engaging the printed circuit board (7). The ground protrusion 9, the engaging projection 2 and the engaging projection 3 which will be in contact with the ground projection 8 was formed.

또한 상기 그라운드 쉴드(1)를 결합할 때에는, 그라운드 쉴드(1)의 외측으로 돌출된 ㄱ자형의 걸림돌기(2)를 샤시(4)의 걸림구멍(5)에 끼우고 눌러주면, 그라운드 쉴드(1)의 다른 측면에 외측으로 기울어져 돌출된 결합턱(3)이 샤시(4)의 벽을 타고 미끄러지다가 샤시(4)의 결합구멍(6)과 결합하게 되어 쉽게 이탈되지 않게 되는데, 제2도는 이런 작용으로 결합된 튜너의 사시도로써, 이 튜너는 뒤집힌 상태에서 솔더링 용액에 인쇄회로 기판(7)의 저면의 잠길 정도로 담갔다가 꺼내고 응고시킴으로써 완성된다.In addition, when the ground shield 1 is coupled to each other, the L-shaped locking projection 2 protruding outward of the ground shield 1 is inserted into the locking hole 5 of the chassis 4 and pressed, and the ground shield ( The engaging jaw 3 protruding outwardly on the other side of 1) slides through the wall of the chassis 4 and engages with the engaging hole 6 of the chassis 4 so that it is not easily detached. Fig. 1 is a perspective view of a tuner coupled by this action, which is completed by immersing the bottom of the printed circuit board 7 in the soldering solution in an inverted state and then taking it out and solidifying.

한편 결합구멍(6)과 결합력(3) 및 걸림구멍(5)과 걸림돌기(2)의 상호 결합상태는 제3도의 단면도를 통해 잘 나타나는데, 걸림돌기(2)는 외측으로 ㄱ자로 돌출되고, 결합턱(3)은 외측으로 비스듬히 기울어져 결합구멍(6)에 걸려있어 그라운드 쉴드(1)가 샤시(4)로부터 이탈되지 않은 상태로 유지된다.On the other hand, the coupling hole 6 and the coupling force (3) and the engaging state of the locking hole (5) and the locking projection 2 is well shown through the cross-sectional view of Figure 3, the locking projection (2) protrudes out to the outside, The engaging jaw 3 is inclined outwardly and hung in the engaging hole 6 so that the ground shield 1 is maintained without being separated from the chassis 4.

상기와 같은 구조 및 작용에 따라, 본 고안은 고정 결합이 확실하게 이루어져서 뒤집을 때 그라운드 쉴드(1)가 이탈되지 않으므로 공정상의 불량 발생율을 최대한도로 줄일 수 있고 또 4면을 모두 잘 맞춘 후에 눌러 결합하는 것에 비해 제조시간을 절약하므로써 제조 공정이 원활해지는 효과가 있는 것이다.In accordance with the structure and action as described above, the present design is a fixed coupling is made to ensure that the ground shield (1) is not detached when flipping, so as to reduce the rate of defects in the process to the maximum and to press all four sides together after pressing well In contrast, the manufacturing process is smoothed by saving manufacturing time.
