ためである。 FIG. 1 is a perspective view showing a conventional tuner mounting structure, in which 1 is a printed board, 2 is a tuner, 3 is a variable resistor whose terminal is connected to the printed board 11 by soldering, 4 is a flyback transformer, 5 is the chassis metal fitting on the right side, 6 is the chassis metal fitting on the rear side, 7
12 is a chassis metal fitting on the left side, and 12 is a tuner holder connected to the chassis metal fitting 7 by inserting screws 12a and 12 (not shown).
The tuner 2 includes a VHF signal input terminal 2a,
A UHF signal input terminal 2b and a plurality of terminals 2c are provided. Tuner 2 in Fig. 1 is a varactor tuner, and is a compact rectangular parallelepiped with six sides shielded with metal plates for reasons such as improving its electrical performance. It is not fixed, but is firmly attached by a tuner holder 12 fixed to the chassis metal fitting 7 as shown in the figure. The reason for this is that if the terminal 2c of the tuner 2 is directly connected to the printed board 1 by soldering, the printed board 1 may be damaged if an impact is applied to the television set.
このようにチユーナ2とプリント板1とが別個
に位置するためチユーナ2の端子2cとプリント
板1の回路との接続はリード線で接続せねばなら

ある。 Since the tuner 2 and the printed board 1 are located separately in this way, the terminal 2c of the tuner 2 and the circuit of the printed board 1 must be connected using lead wires, which requires a large number of assembly steps. This requires parts such as the tuner holder 12 for the purpose of the adjustment, which is also disadvantageous in terms of cost. Furthermore, if the terminals of the tuner are directly connected to the printed board 1, the step of connecting the lead wires can be omitted, but sturdy metal fittings must be used to prevent the printed board from being damaged even if there is an external impact, which is costly. is a big one.

The terminal is directly connected to the printed board 1, and the protruding piece 1a of the printed board 1 is fitted into the notch 8a,
The printed board 1 is held between the "U" shaped part 8a' of the frame 8, and the tip of the protrusion 8c (which has a hole for fixing with a screw) is connected to the screw fixing part 2 of the tuner 2.
Fix the tuner 2 with a screw, and connect it with the VHF antenna terminal 2a' provided on the antenna plate 8b.
The UHF antenna terminal 2b' is connected to the VHF signal input terminal 2a and UHF signal input terminal 2b of the tuner 2, respectively, as shown in FIG.

いる。 The tuner 2 installed as shown in Fig. 2 is the third tuner.
As shown in the figure, screws are passed through small holes 8d formed in the antenna terminal plate 8b, and the antenna terminal plate 8b is fixed to the cabinet 9 of the television receiver. Note that FIG. 3 shows only the cabinet 9 and the cathode ray tube 10. Frame body 8
Furthermore, the notch 11 of the back cover 11 as shown in FIG.
A is inserted into the protruding piece 8e of the antenna terminal plate 8b and fixed as shown in FIG. In the tuner mounting structure of the present invention, the connection from the printed board 1 to other circuits installed on the bottom of the television receiver's cabinet is made using lead wires. Compared to conventional installation work that involves wrapping the product around, it is easier to work with and requires fewer steps. In addition, when the television receiver receives an external shock due to movement or dropping, the frame 8 is removed by the screws 8a and the back cover 11 in the mounting structure of the present invention.
Since the frame body 8 is attached by impact, the frame body 8
Since the whole thing attached to the tuner vibrates, the printed board 1 is prevented from being damaged by the tuner 2.
