部には１部品が面付、挿入。[Operation] The tuner shield cover is assembled to the tuner chassis only during the adjustment and checking process. Therefore, in the assembly process, the same chassis can be used in both the vertically mounted form and the vertically mounted form on the TV main board.6 [Embodiment] An embodiment of the present invention is shown in Figs. This is explained by: Figure 1 shows a tuner consisting of a tuner chassis 1, a tuner shield cover 2, and a terminal 4 (one part is mounted and inserted inside).

いう問題を解決できる。This figure shows a state in which a tuner board 7 (with a soldered tuner board 7) is horizontally assembled to a TV main board 3. TV main board 3
According to this embodiment, the tuner shield cover protrusion 2a and the terminal 4 of the tuner shield cover 2 are inserted into the tuner mounting foot insertion hole 3a and the tuner terminal insertion hole 3b provided in the tuner mounting foot insertion hole 3a and the tuner terminal insertion hole 3b, respectively. , the jet level of the solder 6 in the solder bath 5 when the tuner chassis 1 is mounted vertically on the TV main board 3 is the same as when trying to solder the tuner chassis 1 when the tuner chassis 1 is mounted horizontally on the TV main board 3. Then, the problem of the projection 1a of the tuner chassis coming into contact with the jet nozzle 5a can be solved.

ができ、より品質のよいはんだ付は状態を確保できる。In other words, although production on the same production line would be impossible, since the tuner chassis 1 can be shared, it is possible to use the same production line. Further, since there is no protrusion 1a on the tuner chassis, the height of the jet of solder 6 can be reduced, so that roughness of the solder 6 can be eliminated, and better quality soldering can be ensured.

。In addition, as shown in FIGS. 3 and 4, the tuner chassis 1
By providing a protrusion 1b in and penetrating the tuner shield cover 2, positional accuracy between the terminal 4 and the tuner shield cover protrusion inserted into the television main board 3 is achieved.
［発明の効果コ
本発明によれば、チューナシャーシを共通化できるため
１部品の低減及び、生産工程の効率向上となる。[Effects of the Invention] According to the present invention, since the tuner chassis can be shared, the number of parts can be reduced by one part, and the efficiency of the production process can be improved.
