Description

Grounding structure for shield connection of monitor

The present invention relates to a grounding structure for shield connection of a monitor that connects various shields installed on the outside of each device in the monitor to increase their electromagnetic wave absorption rate, and more specifically, a cathode ray tube socket shield, a top shield, a video shield, The present invention relates to a grounding structure for shield connection of a monitor for connecting a video bracket to one ground plate.

In recent years, as the size of a monitor increases and the resolution thereof increases, the amount of electromagnetic waves generated in a cathode ray tube (CRT) or other devices has increased significantly. Such electromagnetic waves may not only cause malfunctions by affecting nearby devices, but also are particularly harmful to humans, so they are strictly regulated. Therefore, as shown in the monitor exploded perspective view of FIG. 1 of the accompanying drawings, various apparatuses of the monitor are provided with shields for shielding electromagnetic waves which absorb electromagnetic waves generated from these apparatuses and do not emit them to the outside.

On the other hand, when the shields for electromagnetic shielding are electrically connected to each other, the electrical conductivity is increased to increase the electromagnetic shielding effect. Therefore, a monitor is usually used for the shield connection grounding structure which electrically connects each shield for electromagnetic wave shield.

Figure 2 of the accompanying drawings is a rear side cross-sectional view of a monitor using a shielding grounding structure of a conventional monitor.

First, let's look briefly at the main components of the monitor.

In FIG. 2, reference numeral 1 denotes a cathode ray tube, and reference numeral 2 denotes a cathode ray tube socket shield surrounding the cathode ray tube socket substrate. The top shield 3 covers these upper portions, and the video shield 4 is provided on the same plane as the top shield 3 below the top shield 3. The video shield 4 is fixed to the video bracket 5, and the video bracket 5 is screwed to the main shield 6 which serves as a support for each of the components.

In the above structure, the conventional monitor shield connection grounding structure consists of two earth-plates which have elasticity.

One of them (7) is a ground plate formed in the shape of a V-shape, the top shield (3) and the video shield (4) with both ends elastically displaced with the concave portion at the center thereof attached to the cathode ray tube socket shield (2). In contact with the cathode ray tube socket shield 2, the top shield 3 and the video shield 4 are connected.

The other one 8 is hook-shaped and the lower end is in contact with the video bracket 5 while the upper end is attached to the cathode ray tube socket shield 2 to connect the cathode ray tube socket shield 2 and the video bracket 5.

Thus, the cathode ray tube socket shield 2, the top shield 3, the video shield 4, the video bracket 5 and the main shield 6 are two ground plates 7 and 8 of the structure as described above. ), The conductivity is increased, so that the electromagnetic waves emitted from the respective interior parts can be more effectively absorbed.

However, the shield connection grounding structure of the conventional monitor as described above is composed of two independent ground plates 7, 8, as can be seen in the example of the figure, and thus the manufacturing and assembly maneuvering times are large. Had a problem. In addition, the ground plate 7 fixed to the rear surface of the cathode ray tube socket shield 2 is likely to be plastically deformed in the form as indicated by the dotted line. In this case, both ends of the connection portion are the top shield 3 or the video shield 4. ), There was a problem in that the connection between shields was poor.

Therefore, the present invention can eliminate the problems of the shield connection grounding structure of the conventional monitor as described above, and each shield is connected to one ground plate, and even if some deformation occurs, there is no problem in the connection between shields. The purpose of the present invention is to provide a grounding structure for shield connection of a monitor that can reduce manufacturing and assembling work in connecting each shield, and can also solve the problem of connection failure caused by deformation. do.
