Abstract

PURPOSE:To simplify the insertion job in a way of one-touch by providing a bottom rib and a hook projection for regulating the position of a degauss coil to a front cabinet so as to reduce component to fix the degauss coil. CONSTITUTION:A hook projection 5 is installed as a hook shape to a front cabinet 1 to prevent a degauss coil 4 from being fallen down in the direction of a rear cabinet 2. Moreover, a bottom rib 6 regulates the position of the degauss coil 4 to the bottom face. Then the degauss coil 4 is fixed while being clipped by a CRT 3, the hook projection 5 and the bottom rib 6. ln this case, the gap between the CRT 3 and the hook projection 5 is a gap through which no degauss coil 4 passes and in the case of insertion, since the front cabinet 1 is an elastic body formed by a plastic or the like, the elasticity is utilized to deform the projection 5 tentatively in the direction of arrow (b) to insert the degauss coil 4. Thus, number of components is reduced and the job is simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a degaussing coil fixing device used for fixing degaussing coils in television receivers, display monitors, and the like.

2. Description of the Related Art In recent years, degaussing coil fixing devices have been widely used to fix a degaussing coil for the purpose of demagnetizing a cathode ray tube at a certain position on a cathode ray tube.

A conventional degaussing coil fixing device will be explained below with reference to the drawings.

Figures 3, 4, and 5 show conventional degaussing coil fixing devices, and 3 in Figure 3 shows a cathode ray tube (hereinafter referred to as CRT).
), 7 is the front cabinet to which the CRT 3 is fixed with screws. Reference numeral 2 denotes a rear cabinet, which is also fixed to the front cabinet by fixing means (not shown) such as screws. FIG. 5 is a detailed view of part d in FIG. 3, and 9 is a seven-lunge mounting bracket installed on the CRT 3.

10 is a screw, and 11 is a wire stopper, which is a thin metal piece covered with a vinyl tube, and by wrapping it around the lead wire, the position can be regulated while preventing damage. 4 is a demagnetizing coil.

The operation of the degaussing coil fixing device configured as above will be explained below.

First, the wire stopper 11 and the flange 9 are fastened to the boss 8 with the screws 10. Then, as shown in FIG.
By winding the demagnetizing coil 4 around the CRT 3, the degaussing coil 4 can be fixed at a certain position on the CRT 3.

Problems to be Solved by the Invention However, in the above configuration, the wire stopper 11
must be used as a dedicated part. Further, the cost increases due to the need for winding work.

Furthermore, even if an attempt was made to mechanize the work of screwing the CRT 3 to the front cabinet 7, the machine would not be able to tighten the wire fixing fittings 1l at the same time, and the screws would have to be screwed in manually, resulting in low productivity. had.

In view of the above problems, it is an object of the present invention to provide a degaussing coil fixing device that reduces the number of parts, simplifies work, eliminates joint tightening, and can be adapted to mechanized screw tightening.

Means for Solving the Problems In order to achieve the above object, the degaussing coil fixing device of the present invention eliminates the use of wire fixing fittings and has a bottom rib on the front cabinet for regulating the position of the degaussing coil, and a rib for preventing the degaussing coil from coming off. A hook-shaped protrusion is installed.

Operation With the above configuration, the degaussing coil is inserted into the front cabinet and the bottom rib is inserted. It becomes possible to regulate and fix the position by the CRT and the hook-shaped protrusion.

EXAMPLE Hereinafter, a degaussing coil fixing device according to an example of the present invention will be described with reference to the drawings.

FIG. 1 shows a cross-sectional view of a display monitor equipped with a degaussing coil fixing device of the present invention, and FIG. 2 shows a cross-section aa of FIG. 1. In FIG. 1, 1 is a front cabinet, and 2 is a rear cabinet, which are fixed to the front cabinet 1. 3 is C
RT, 4 is a degaussing coil, 5 is a hook-shaped protrusion, which is installed in the front cabinet 1 in a hook shape, and the degaussing coil 4
This prevents it from falling toward the rear cabinet 2. A bottom rib 6 restricts the position of the degaussing coil 4 toward the bottom side.

Regarding the degaussing coil fixing device configured as above,
The operation will be explained below.

In FIG. 1, the degaussing coil 4 is connected to the CRT 3. It is sandwiched between the hook-shaped protrusion 5 and the bottom rib 6 and is fixed under position regulation. In this case, the CRT 3 and the hook-shaped protrusion 5
The gap is such that the degaussing coil 4 cannot pass through, but when inserting the front cabinet 1, since the front cabinet 1 is an elastic body made of plastic or the like, its elasticity can be used to The degaussing coil 4 can be inserted by temporarily deforming the hook-like protrusion 5.

As described above, according to this embodiment, by providing the bottom rib and the hook-shaped protrusion for regulating the position of the degaussing coil on the front cabinet, the number of parts can be reduced, the insertion work can be simplified, and joint tightening can be eliminated. It can also be used to mechanize screw tightening.

In this embodiment, the hook-shaped protrusion 5 is provided on the front cabinet 1, but the hook-shaped protrusion 5 may be formed integrally with the front cabinet, or may be formed into a boss, a boss, or an adhesive. .

Effects of the Invention According to the present invention, by providing the front cabinet with a bottom rib and a hook-like protrusion for regulating the position of the degaussing coil, the number of parts for fixing the degaussing coil can be reduced and the insertion work can be simplified with one touch. , it is possible to eliminate the need for joint tightening of the above parts and to support mechanization of screw tightening.
