Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a back cover, and particularly to a mechanism for assembling the back cover to a cabinet and a chassis in a television receiver.

Figure 1 is a vertical cross-sectional view of a television receiver showing the conventional back cover assembly to show the mechanism, and Figure 2 is a partial rear view of the assembly of the chassis to the cabinet in Figure 1 showing the details of the mechanism. It is a diagram.

In the figure, the chassis legs 4 are L-shaped, have cut and raised holes 11 with round holes, and are symmetrically paired at the bottom of the chassis 3.

The cabinet 1 also has a pair of L-shaped grooves 5 on the bottom into which the above-mentioned cross-shaped chassis feet 4 can be inserted, and also has tapping holes 7 that match the round holes of the above-mentioned cut-and-raised holes 11. have.

Note that the plug 8 is fixed to the chassis 3, and
A socket 10 connected to a power cord 9 is fixed to the back cover 2.

In the above configuration, the chassis 3 is assembled by inserting the chassis legs 4 into the L-shaped grooves 5 and fixing them with the tapping screws 6.

Next, the back cover 2 is assembled to the cabinet 1, but at this time, the socket 10 must be inserted into the plug 8.

However, in the conventional mechanism, there is no proper positioning between the cabinet 1 or chassis 3 and the back cover 2, and the plug 8 and socket 10 are both located inside the receiver and are difficult to see from the outside. In addition, it was difficult to insert the socket 10 into the plug 8, and the state of insertion could not be confirmed from the outside, leading to incorrect insertion.

The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to provide a back cover assembly mechanism that allows easy and reliable assembly.

In order to achieve this purpose, according to the present invention, the back cover is also provided with an L-shaped groove similar to that of the cabinet, so that the chassis foot is fixed across the cabinet and the back cover. is inserted into the plug securely, and the back cover can be assembled easily and reliably.

Next, an embodiment of the back cover according to the present invention will be described with reference to the drawings.

Fig. 3 is a vertical sectional view of the television receiver to show this embodiment, Fig. 4 is a partial rear view showing details of the mechanism for assembling the chassis into the cabinet, and Fig. 5 is a partial rear view showing details of the mechanism for assembling the chassis into the cabinet. It is a partial perspective view of the back surface of a back cover showing details.

In the figure, the chassis foot 4' is L-shaped, has a length that spans the cabinet 1 and the back cover 2', and is provided with a raised cut 11 with a round hole for passing the tapping screw 6. They form a symmetrical pair at the bottom.

The cabinet 1 has an L-shaped groove 5 into which an L-shaped chassis foot 4' can be inserted, and also has a tapping hole 7 at a position matching a round hole provided in the cut-and-raised part 11.

On the other hand, the back cover 2' is also provided with an L-shaped guide groove 12 at a position facing the L-shaped groove 5 of the cabinet 1, into which the chassis foot 4' can be inserted.

In addition, the plug 8 is fixed to the chassis 3, and the power cord 9
10 is fixed to the back cover 2'.

The positional relationship between the cabinet 1, the back cover 2', and the chassis 3 is such that the plug 8 and the socket 10 connected to the power cord 9 are inserted into each other during assembly.
It is positioned by the L-shaped groove 5, the L-shaped guide groove 12, and the chassis foot 4'.

The assembly will be explained below.

To assemble the chassis 3, the chassis foot 4' is inserted into the L-shaped groove 5, passed through a round hole provided in the raised cut 11, and fixed into the tapping hole 7 with a tapping screw 6.

At this time, the chassis leg 4' protrudes to the rear of the cabinet 1 by a length extending over the back cover 2'.

Furthermore, the back cover 2' can be assembled by inserting the L-shaped guide groove 12 using the portion of the chassis foot 4' protruding from the rear of the cabinet 1 as a guide as described above.

In this case, since the plug 8 and the socket 10 are positioned, the back cover 2' can be easily assembled without causing any insertion failure between the plug 8 and the socket 10.

As mentioned above, according to the present invention, when assembling the back cover, there is no possibility of incorrect insertion of the plug and socket.
The effect of assembling the back cover is that it becomes very easy to assemble the back cover.
