Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cord attachment device that can be used in electrical equipment such as television receivers.

Conventional configurations and their problems In recent years, the systemization of audio equipment and video equipment has progressed, and television receivers have also become more compact and standardized in external dimensions in relation to other equipment, and the tolerances inside the cabinet have increased. has become extremely small.

Conventionally, a device as shown in FIG. 1, for example, has been used as a power cord attachment device.
This connects one end of a power cord 2 to a chassis 1, and connects a groove 4 provided on the periphery of a bushing 3 that is fitted into the power cord 2 or formed integrally with the power cord 2 to a back cover. The power cord 2 is fixed by fitting into a notch 6 provided in the back cover 5 and fitting an end of the back cover 5 into a hook 8 provided at the rear end edge of the cabinet 7.

FIG. 2 shows a side cross section of the above conventional example.
The chassis 1 is attached to the cabinet 7 with a chassis metal fitting 9, and the power cord 2 connected to the chassis 1 is fitted into the groove of the bushing 3 through the notch 6 provided in the back cover 5 to fix the power cord.
The power cord 2 is configured to be pulled out to the outside of the cabinet 7.

However, in the conventional configuration as described above, when the internal space of the cabinet 7 is reduced due to the miniaturization of the cabinet 7, the distance between the chassis metal fitting 9 and the cord, that is, the dimensions of H and D becomes smaller, and the power cord 2 becomes smaller. There were drawbacks such as the possibility of contact with live parts such as the chassis metal fittings 9.

OBJECT OF THE INVENTION The present invention aims to eliminate the above-mentioned conventional drawbacks, and provides a cord attachment device that has a simple configuration and can stably attach the power cord so that it does not come into contact with live parts of the chassis. This is what we provide.

Structure of the Invention In the present invention, the bushing is provided with a protrusion that fits into the groove of the cord stopper bushing that is fitted into the cord or is formed integrally with the power cord, and the concave groove that holds the cord stopper bushing is fixed to the bushing. A thin hinge part is provided at the center of the bushing fixture at both ends of one side of the bushing fixture, and a groove that fits into the notch of the back cover is integrally provided on the other side of the bushing fixing fixture. Then, using the thin part of this bushing fixing device as a hinge, hold the bushing between the notches provided with protrusions and bend it so that the grooves that fit into the notches of the back cover are located on both sides, and then attach the bushing to the notch of the back cover. The cord is attached by inserting and mating.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 3A and 3B, the resin cord attachment device 19 of the present invention is divided into two halves 19A and 19B using a thin walled portion provided at the center of one end side as a connecting hinge. On the parting line side of each half 19A, 19B, there is a protrusion 13A that fits into a groove 12 provided in a cord stopper bushing 11 that fits into the power cord 10 or is formed integrally with the power cord 10. , 13B, and cut recesses 24A and 24B for holding the outer peripheral portion of the cord fixing bushing 11 are formed in a U-shape, respectively. Further, a V-shaped notch 14 is provided at the upper left corner of the U-shaped recess of one protrusion 13B, and a groove 17 is provided to fit with a protrusion 16 provided at the end of the other protrusion 13A. Furthermore, each half 19
At the center of the lower ends of A and 19B, a thin hinge part 15 is provided which connects each half body in an openable and closable manner. Further, each of the halves 19A and 19B is integrally formed with a groove 18 on the side opposite to the side on which it is provided, which fits into the notch of the back cover.

Then, the center thin part of the cord attachment device 19 on the side opposite to the side on which the protrusion 16 is provided is used as the hinge 15, and the protrusions 13A, 13B and the groove 1 of the bushing 11
2, and the protrusions 16 and notches 17 at the ends of the U-shaped protrusions 13A and 13B are fitted to hold the bushing 11, so that the grooves 18 that fit with the notches of the back cover are located on both sides. Fold. In this state, as shown in FIG.
Insert the power cord by fitting it into the notch 21 made in the hole and attach the power cord.

In this case, the distance between the chassis 23, which is attached to the cabinet with chassis metal fittings, and the back cover 20 is extremely narrow, but the bushing fixture allows the power cord pull-out part to be installed apart from the chassis 22, so there is no need to worry about live parts. It is possible to prevent contact with

Effects of the Invention As described above, according to the present invention, by integrally assembling the cord-fastening bushing and the bushing fixture in advance using the bushing fixture, the workability can be improved without significantly changing from the conventional method, and the structure is simple. The power cord can be attached so that the cord does not come into contact with live parts, and the cabinet can be made smaller.
