본 발명은 텔레비전 수상기 등에 사용되는 튜너 하우징의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a tuner housing for use in television receivers and the like.

종래, 이러한 종류의 튜너 하우징의 제조시에는, 외부 하우징과 내부의 격벽을 각기 별도로 펀칭하고, 외부 하우징에 격벽을 UHF와 VHF용 각각의 고주파 증폭부, 국부발진부 및 혼합부와, UHF와 VHF공용의 IF출력부 등으로 구획하여 납땜으로 부착하고 있었다.Conventionally, in the manufacture of this type of tuner housing, the outer housing and the inner partition wall are punched separately, and the partition wall is formed in each of the high frequency amplification unit, the local oscillation unit and the mixing unit for the UHF and VHF, and the UHF and VHF common use. Is separated by the IF output part and the like and soldered.

이 때문에, 종래의 제조방법에서는 프레스펀칭 공정 외에 격벽의 납땜 공정이 필요해져서 공정수가 많아질 뿐만 아니라, 이 납땜이 불량할 경우에는, 격벽이 떨어지거나, 떨어지지는 않더라도 격벽에 의한 블록간의 격리작용이 충분히 행해지지 않게 되는 염려가 있었다.For this reason, in the conventional manufacturing method, not only the press punching step but also the soldering step of the partition wall is required, and the number of steps is increased. There was a concern not to be done enough.

본 발명은 이와 같은 점을 감안하여 이루어진 것으로서, 1매의 금속성 평판에서, 튜너 하우징을 형성하는 전후판 및 좌우측판과 복수개의 격벽을 일체적으로 펀칭하는 동시에, 적당한 가공성형을 가함으로써, 격벽의 납땜 공정을 불필요하게 한, 대량 생산에 적합한 튜너 하우징의 제조방법을 제공하는 것이다.SUMMARY OF THE INVENTION The present invention has been made in view of such a point, and in one metallic flat plate, the front and rear plates and the left and right plates forming the tuner housing are integrally punched and a suitable processing molding is applied to the partition walls. It is to provide a method of manufacturing a tuner housing suitable for mass production, which eliminates the soldering process.

이하 도면에 나타낸 실시예를 참조하면서 본 발명의 제조공정을 설명한다.Hereinafter, the manufacturing process of the present invention will be described with reference to the embodiments shown in the drawings.

여기서는 먼저 미리 표면에 도금처리를 실시한 1매의 금속성 평판(1)을 준비한다. 그리고 이 평판상에 인발가공을 실시하고, 제1도에 나타낸 바와 같이 소정위치에 선형돌출부(2), (2)…나 환상돌출부(3)를 형성한다. 이 덮개 걸림용의 선형 돌출부(2), (2) … 는 하우징 완성시에 시일드 덮개의 부착용으로서 이용되며, 환상돌출부(3)는 안테나 입력단자의 부착용으로서 사용된다.Here, first, the metallic flat plate 1 which previously plated the surface is prepared. Then, drawing is carried out on the flat plate, and as shown in FIG. 1, the linear protrusions (2), (2)... And the annular projection 3 is formed. Linear projections 2, 2 for locking the lid. Is used for attachment of the shield cover at the time of completion of the housing, and the annular projection 3 is used for attachment of the antenna input terminal.

다음에 상기 평판(1)에 프레스 펀칭가공을 실시하여, 제2도에 나타낸 바와 같이 하우징 완성시에 전판(4), 후판(5), 및 좌우의 측판(6), (7)을 형성하는 부분과 10개의 격벽(8), (8) …을 형성하는 부분을 서로 연결한 상태에서 불필요한 위치(제2도에 있어서 교차 사선으로 나타냄)를 펀칭한다. 이와 동시에 안테나 입력단자 부착구멍(9) 및 그 밖의 입력단자 부착구멍(10), (10) … 과 하우징 조립시의 끼워맞춤구멍(11), (11) …을 뚫어서 설치한다.Next, press punching is applied to the flat plate 1 to form the front plate 4, the rear plate 5, and the left and right side plates 6 and 7 at the time of housing completion as shown in FIG. Part and ten partitions 8, 8. Unnecessary positions (indicated by crossed diagonal lines in FIG. 2) are punched in a state in which portions forming the cross sections are connected to each other. At the same time, the antenna input terminal attaching hole 9 and other input terminal attaching holes 10, 10. Fitting holes 11 and 11 during housing assembly; Install by drilling.

그리고 다음에 다시 평판(1)의 프레스 펀칭가공을 실시하여 제1도 및 제2도에 있어서 점선으로 나타낸 외형으로 평판(1)을 펀칭한다. 이때 제3도에 나타낸 바와 같이, 마치 전개도와 같은 하우징용 금속성 평판이 얻어진다.Next, press punching is performed again on the flat plate 1, and the flat plate 1 is punched to the outline shown by the dotted lines in FIG. 1 and FIG. At this time, as shown in Fig. 3, a metallic flat plate for housing is obtained as if it were a developed view.

그런 연후에 상기 평판의 절곡가공을 실시하여, 제3도에 점선으로 나타낸 라인을 따라 전판(4), 후판(5), 측판(6), (7), 및 격벽 (8), (8) …을 순차적으로 직각으로 절곡하는 동시에, 각판(4), (5), (6), (7) 및 격벽(8), (8) …의 끝 가장자리에 미리 돌출설치되어 있는 끼워 맞춤 돌출부(12), (12) …를 끼워 맞춤 구멍(11), (11) …에 각기 끼워 맞추고, 또한 그 선단을 비틀므로써, 제4도에 나타낸 바와 같은 튜너 하우징의 조립이 완료된다. 이 경우의 튜너 하우징은 격벽(8), (8) …에 의해 8개의 블록으로 구획된다.Afterwards, the plate is bent, and the front plate 4, the rear plate 5, the side plates 6, 7, and the partitions 8, 8 along the lines indicated by the dotted lines in FIG. … Are sequentially bent at right angles, and each plate 4, 5, 6, 7 and partitions 8, 8. Fitting projections 12, 12 provided in advance at the end edges of the edge; Fitting holes 11 and 11. The assembly of the tuner housing as shown in FIG. 4 is completed by fitting in each and twisting the front end. In this case, the tuner housings are partition walls 8, 8. It is divided into eight blocks by.

그리고 상기와 같은 방법으로 작성된 튜너 하우징은, 그 후 안테나 입력단자나 그 밖의 입출력 단자가 부착되며, 또 하우징 저면에는 회로부품이 실장된 프린트 기판이 부착되고, 또 상, 하면에 시일드 덮개가 부착된다.The tuner housing prepared by the above-described method is followed by an antenna input terminal or other input / output terminals, a printed circuit board on which circuit components are mounted on the bottom of the housing, and a shield cover on the upper and lower surfaces. .

본 발명의 튜너 하우징의 제조방법에 의하면, 상기와 같이 1매의 금속성 평판에서, 튜너 하우징을 형성하는 전후판 및 좌우측판과 복수개의 격벽을 서로 연결한 상태로 펀칭하는 동시에 그후 절곡가공을 실시하여 작성하고 있기 때문에, 종래와 같이 하우징에 별도로 격벽을 부착하여 납땜할 필요도 없어서 공정이 간략화 되므로 튜너 하우징의 대량생산에 매우 유리해지며, 또 격벽에 의한 각 블록간의 격리작용도 충분해진다.According to the manufacturing method of the tuner housing of the present invention, as described above, by punching in a state in which the front and rear plates and the left and right plates forming the tuner housing and the plurality of partition walls are connected to each other, and then bent. Since it is not necessary to attach and solder a partition to the housing separately as in the prior art, the process is simplified, which is very advantageous for mass production of the tuner housing, and the isolation between the blocks by the partition is also sufficient.
