DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a degaussing coil mounting apparatus according to the present invention will be described below with reference to the drawings. In FIG.
The CRT 1 has a built-in shield case, around which a metal band 3 for maintaining the strength of the CRT 1 is attached, as can be understood from FIG.

As shown in FIGS. 2 and 3, the metal band 3 is provided with a holder mounting portion 5 having a shape rising from the metal band 3 toward the rear of the CRT 1.
When the holder 7 is inserted toward the holder mounting portion 5 from behind the CRT 1 as shown in FIG. 2, the holder 7 is locked to the holder mounting portion 5 as shown in FIG. When the holder 7 is locked and mounted in this way, as can be understood from FIG. 3, the flat portions of the metal band 3, the holder 7 and the DGC 9 are clamped, and Pressed and fixed to the band 3.

[0010] As can be understood from FIG.
A hook hole 7A is formed at one end of a hanging band 11 made of plastic or the like having both ends in a hook shape. The hook hole 7A is locked at the other end of the hanging band 11, and one DGC 9 is locked at the other end.

Further, one DGC 9 and the other DGC 9 are connected and fixed by a holding band 13, whereby
Positioning of the entire C9 is performed.

Further, in this embodiment, the ground braided wire 15 having the crimp terminal is attached to the holder attaching portion 5, and the shape of the braided wire 15 is held by the tension spring 17.

One end of the tension spring 17 is fixed to the metal band 3.

Therefore, the mounting position of the braided wire 15 is located on the near side as compared with the conventional method in which the braided wire 15 is mounted on the ear of the CRT 1, so that the work of mounting the braided wire 15 can be performed easily.

As described above, in this embodiment, D
Since the GC 9 is attached to the holder 7 and the suspension band 11, the DGC 9 can be held in close contact with the CRT 1.

After the CRT 1 is mounted on the cabinet, the DGC 9 can be mounted from the rear, so that the assembling workability is good.

In addition, since the DGC 9 is designed to be flat, the DGC 9 is fixed only by pressing the holder 7, so that compactness is possible.

Further, the suspension band 11, the holding band 13
By using the method, the position of the DGC 9 can be easily determined.

[0019]

As will be understood from the above description, in the degaussing coil mounting apparatus according to the present invention, the degaussing coil is held by the holder and the suspension band.

Accordingly, the degaussing coil can be held in close contact with the CRT.

Further, the holder is attached to the holder mounting portion from the rear of the CRT by the holder attaching portion and the holder provided at an appropriate position of the metal band attached to the outer periphery of the CRT toward the rear of the CRT. Each of the pair of coils constituting the degaussing coil can be pressed and fixed to the metal band portion by being engaged, so that the degaussing coil can be easily and securely mounted, and the degaussing coil can be mounted on the CRT. The workability is good, and the attachment position can be reliably held. Therefore, after the CRT is mounted on the cabinet, this CR
The remarkable improvement in the assembly workability when attaching the degaussing coil to T is remarkable.

In addition, since the degaussing coil is designed to be flat, the degaussing coil is fixed only by pressing the holder, so that compactness can be achieved.

Further, in general, it is difficult to locate the demagnetizing coil because it is an indefinite type. However, the use of the suspension band facilitates the positioning.
