Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a simple structure for removing static electricity from the front glass of a CRT display screen.

Prior Art Generally, in order to remove noise and static electricity from the display surface of a CRT, etc., the glass 1 of the display surface is coated with a transparent conductive film 2 or a conductive mesh is attached, as shown in FIG. In order to attach the lead wire 3 to the conductive film 2 or the conductive mesh, a hole 4 is provided in the front glass 1, a screw 5 or caulking material is passed through the hole 4, and a nut 6 is fixed to the screw 5, or The conductive film 2 is connected to the lead wire 3 by caulking the lead wire to the caulking material.

Problems to be Solved by the Invention However, in the conventional static electricity removal structure of the front glass of a CRT display screen, the screws 5 and the caulking material appear to protrude from the front of the front glass 1, resulting in an unsightly appearance. Drill hole 4,
Because they are fastened with screws or nuts through which the caulking material is passed, or by caulking, there is a problem in that manufacturing is time-consuming and costs are high.

Means for solving the problems In order to solve the above problems, this invention
In the front glass provided in front of the display surface and coated with a conductive film on the entire display surface side of the CRT, a large number of protrusions are provided on the copper foil, and a conductive tape coated with adhesive on the protrusion side is attached to the front surface of the CRT. It is characterized in that it is adhered to a part of a glass conductive film, and a lead wire is soldered to the conductive tape.

Function According to the present invention, a conductive tape is glued onto the conductive film of the front glass, and a lead wire is soldered to this conductive tape, so the structure is simple and the conductive film can be connected from the front of the front glass. Because I can't see anything
Looks good.

Embodiment Figure 1 is a cross-sectional view of a structure for removing static electricity on the front glass of a CRT display screen according to an embodiment of the present invention. 1 is the front glass, 2 is a conductive film, and these structures are the same as the conventional example described above. Therefore, the explanation will be omitted, but
In this embodiment, a conductive tape 7 is adhered onto the conductive film 2. As shown in FIG. 2, when this conductive tape 7 is poked with a cone-shaped object from one side of the copper foil, many protrusions 8 will protrude from the other side. Apply. When this conductive tape 7 is adhered onto the conductive film 2, a large number of protrusions 8
protrudes from the adhesive 9 and comes into contact with the conductive film 2 for electrical conduction. Therefore, by fixing the lead wire 3 on the conductive tape 7 adhered to the conductive film 2 by soldering 10, the conductive film 2 and the lead wire 3 are electrically connected, and the front glass 1 Static electricity charged on the surface can be removed.

In the static electricity removal structure of the front glass of this example,
Since the conductive tape 7 is not visible from the surface of the front glass 1, there is an advantage that the appearance is good, and the connection of the lead wire 3 is also easy.

Effects of the invention As is clear from the above explanation, the present invention involves bonding a conductive tape onto the conductive film of the front glass.
Since the lead wires are soldered to this conductive tape, the structure is simple, the lead wires can be easily soldered, and since nothing can be seen from in front of the front glass, it has the advantage of looking good. .
