It is.

Prior Art FIG. 4 is an exploded perspective view showing a typical conventional example of the present invention. In this figure, 11 is a character multiple bag covered with a steel plate frame with t = 0.8 and an iron plate top lid with t = 0.3;
Reference numeral Ila denotes a mounting hole, and the four mounting holes, two at the top and two at the bottom, correspond to boss mounting holes 16a inside the side surface of the television receiver 16. Reference numeral 12 denotes a satellite broadcasting back covered with a steel plate with t=O, S, and 12a is its mounting hole.The four mounting holes, two at the top and two at the bottom, correspond to the holes 19a of the back cover 19. 15 is a screw, 16
is a television receiver with built-in text multiplexing and satellite broadcasting, 16a
This hole corresponds to the mounting hole 19a of the back cover 19, and the back cover 19 is attached and detached using screws 15. 17 is a neck portion of the cathode ray tube, 17a is a neck board thereof, 18 is a wiring board of the television receiver 16, and 19 is a back cover made of plastic molding.

In this configuration, first, the hole 11a of the character multiplex bag 11 is fitted into the hole 16b on the inner surface of the television receiver 16, and after temporary fixing, the screw 5 is passed through the hole 11a and fixed to the hole 16a. Next, fit the hole 12a of the satellite broadcast pack 12 into the hole 19a of the pack cover 19, and after temporarily fixing the screw 5 into the hole 19.
There is a method of fitting the mounting hole 19b of the back cover 19, which is screwed into the hole 12a through the hole 12a, into the hole 16a of the television receiver 16, passing the screw 5 through the hole 19b, and screwing it into the hole 16a. This method has the advantages of a simple mounting structure and reliable mounting.

Problems to be Solved by the Invention In recent years, television receivers with built-in text multiplexing backs and satellite broadcast packs have been produced in high-inch size television receivers, but they have also been introduced into low-inch size television receivers. Therefore, with the mounting structure configured as described above, the built-in pack could not be easily incorporated into the narrow gap inside the television receiver.

In view of the above problems, the present invention provides a coupling device that allows a built-in pack to be incorporated into a narrow gap inside a small-inch television receiver.

Means for Solving the Problems In order to solve the above problems, the coupling device of the present invention connects a first pack, such as a satellite broadcasting receiver, and a second pack, such as a teletext receiver, to an insulating first pack. It is fixed using a second molded product and a screw, and can be attached and detached using a screwdriver.

Effect: With this configuration, the first pack can be replaced without changing the mold of the first pack.
．． A low cost coupling device for attaching and detaching the second pack can be provided.
