Abstract

PURPOSE:To improve workability and to prevent the falling trouble of a degaussing coil by integrally forming a projected holding part which has the holding structure of the degaussing coil in combination with CRT in a substrate holder. CONSTITUTION:The holding part 7 is provided with the inclined surface 4a of CRT 4, the inclined surface 7a which is inserted from a posterior side (shown as an arrow) to the front face side so as to be abutted and an almost L-shaped notched part 7b formed at the front end part of the diagonal surface 7a. In this case, when the substrate holder 2 which is integrally formed by the degaussing coil and CRT holding part 7 is inserted from the posterior side of CRT 4 and fixed at a prescribed position, the degaussing coil 5 is held by the degaussing coil notched part 7b so as to be fixed and, at the same time, CRT 4 is held. That is, a screw stop is eliminated and also degaussing coil fixing structure is integrally formed so that the number of parts is reduced and fixing work is executed by one operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holding device such as an image display device, and more particularly to an internal substrate holder.

[0002]

2. Description of the Related Art FIGS. 2 and 3 show a conventional method for fixing a CRT holder and a degaussing coil.
Reference numeral 1 is a CRT holder, 2 is a substrate holder, 3 is a fastening screw for attaching these, 4 is a CRT, 5 is a degaussing coil, and 6 is a clamper.

Next, the assembling mode will be described. First, as the CRT holding mechanism, the CRT holder 1 is attached to the left and right front portions of the substrate holder 2 with the screws 3, and the inclined surface 1a is brought into contact with the inclined back surface 4a of the CRT 4 so that the CRT is held.
4 support. On the other hand, as the degaussing coil holding mechanism,
The clamper 6 is inserted into the small hole 4c of the projecting piece 4b provided on the CRT 4, and the degaussing coil 5 is passed through the annular clamper portion 6a at the tip of the clamper 6 and fixed.

[0004]

Since the conventional CRT holding mechanism is constructed as described above, it is necessary to use screws, and it is necessary to manage the tightening torque.
Moreover, since a driver is used, there is a problem in workability. Further, with respect to the degaussing coil holding mechanism, there is a problem that it takes time and effort to insert the clamper and the clamper easily comes off.

The present invention has been made to solve the above problems, and an object thereof is to improve workability and prevent the degaussing coil from falling off.

[0006]

A cathode ray tube holding device according to the present invention comprises a substrate holder integrally formed with a projection-shaped holding portion having both a holding mechanism for a CRT and a degaussing coil.

[0007]

In the substrate holder with the degaussing coil and the CRT holding mechanism according to the present invention, the projection having both the CRT holding mechanism and the degaussing coil holding mechanism is integrally molded, and the screwing is eliminated, so that the assembling work is greatly simplified. .

[0008]

EXAMPLES Example 1. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 2 is a substrate holder, 4 is a CRT, 5 is a degaussing coil, and 7 is a degaussing coil and a CRT holding part which are integrally molded on the substrate holder 2. The holding portion 7 has an inclined rear surface 4a of the CRT 4 and an inclined surface 7a which is inserted from the rear side (arrow) toward the front side and comes into contact with the inclined rear surface 4a.
And a substantially L-shaped notch 7b formed at the front end of the inclined surface 7a.

Next, the operation will be described. Degaussing coil
The CRT holding part 7 is integrally molded, and the substrate holder 2 is a CRT.
When it is inserted from the rear of 4 and fixed at the specified position (state shown in the figure), the degaussing coil 5 is sandwiched and fixed by the degaussing coil notch 7b, and the CRT 4 is also held at the same time.

[0010]

As described above, according to the present invention, the screwing is eliminated and the degaussing coil fixing mechanism is integrally provided, so that the number of parts is reduced and the fixing work can be performed with one touch, thus improving workability. In addition, since the degaussing coil is sandwiched between the CRT and the holder, it also has an effect of suppressing variations in product performance due to variations in the position of the degaussing coil.
