Description

[Detailed description of the invention] The present invention relates to a picture tube mounting device for a television receiver.
In particular, consideration has been given to making it possible to securely attach the picture tube and, at the same time, to fix the cabinet front frame to the cabinet body.

The installation of the picture tube in a conventional television receiver is
Generally, mounting ears provided at the four corners of the picture tube are fixed with bolts and nuts installed in the front frame of the cabinet.

However, if the picture tube is fixed in this way when both the front frame and the cabinet body are made of synthetic resin, the picture tube will not fall because only the front frame directly supports it. When subjected to shocks such as time, the entire weight of the picture tube is applied directly to the joint between the front frame and the cabinet body, resulting in the front frame easily coming off from the cabinet body or damaging the joint between the two. It turns out.

Therefore, as an alternative to such a structure, the applicant proposes the first
The mounting device shown in Figs. and 2 was previously proposed.

That is, in this device, a box-shaped mounting body 2 as shown in FIG. 2 is integrally formed at the four corners of the front frame 1 of the cabinet around the picture tube mounting portion, and bolts 3 for fixing the picture tube are fixed therein. The seat plate 4 is fitted onto the upper surface of each mounting body 2 and fixed by adhesive.

As shown in FIG. The support piece 7 is fixed with adhesive.

Then, with the front frame 1 and the cabinet body fitted together, first, the support piece 7 is tightened and fixed to the boss 9 integrally molded on the seat plate 4 with self-tapping screws 8, and then the picture tube Mounting ears 11 at the four corners of the side surface of the housing 10 are fixed with the bolts 3 and nuts 12.

According to this structure, the front frame 1 and the cabinet body 5 are fixed at each attachment point of the picture tube 10, so the front frame 1 and the cabinet body work share the weight of the picture tube 10 and support it. Therefore, there is an advantage that the above-mentioned drawbacks can be eliminated.

However, on the other hand, the work of fixing the front frame 1 to the cabinet body 5 with the screws 8 is required separately from the work of fixing the picture tube with the bolts 3 and nuts 12, which has the disadvantage of requiring a large number of man-hours. .

Therefore, the present invention proposes a new picture tube mounting device that eliminates the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to FIGS. 3 to 7.

FIG. 3 is a plan view of the synthetic resin cabinet front frame as seen from the back side.

The front part of the front frame is provided with a window part 22 to which the control panel is attached and a window part 23 from which the front surface of the picture tube is exposed, and a fitting step part 24 is formed at the periphery of the rear opening end. There is.

"And here, in particular, a semi-cylindrical post 26 having a through hole 25 as shown in FIG. 5 is integrally molded at the four corners around the window 23.

On the other hand, FIG. 4 is a plan view of the cabinet body 2 made of synthetic resin, viewed from the back side similarly to FIG. 3.

The front surface of this cabinet body is provided with windows 28 and 29 similar to those shown in FIG. 3, and the peripheral edge of the front surface is provided with a fitting step 24' that engages with the step on the front frame side. There is.

Here, in particular, connecting members 30 made of synthetic resin having a shape as shown in FIG. It is characterized by what it did.

Furthermore, a hook 32 for attaching a picture tube degaussing coil is integrally molded into the coupling member 30 together with a through hole 31 .

Therefore, in order to assemble the cabinet main body 27 and the front frame 21 and fix the picture tube, first, the rear opening side of the front frame is butted against the front side of the cabinet main body 1, and the mating step between the two is first aligned. 24 and 24' are fitted together.

At this time, the coupling member 30 on the cabinet body side abuts against the post 25 on the front frame side, and the through holes 25 and 31 of both of them match.

Therefore, in this state, as shown in FIGS. 5 and 6,
Mounting ears 3 provided at the four corners of the side surface of the picture tube 23
4 on the coupling member 30, and both 30,
By screwing the self-tapping screw 36 inserted through the through holes 31 and 35 of 34 into the through hole 25 of the post 26, the installation of the picture tube 33 and the connection and fixation of the front frame 21 and the cabinet body 27 are completed. be.

FIG. 7 is a side sectional view of the assembled state, and the rear opening side of the cabinet body 27 is separately covered with a bank cover (not shown).

In the above embodiment, the coupling member 30 is fixed to the inner wall surface of the cabinet body by adhesive, but the coupling member 30 may be integrally molded with the cabinet wall surface.

Since the picture tube mounting device of the present invention has the structure as described above,
Attachment of the picture tube and fixation of the front frame to the cabinet body can be performed at the same time, and therefore, the number of work steps when assembling the television receiver can be significantly reduced.

Additionally, since the weight of the picture tube is shared between the front frame and the cabinet body, the impact force when it falls is not concentrated on the joint between the front frame and the cabinet body, and the front frame can therefore come off. It will not be damaged or damaged.
