[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conductive transparent body suitable for use in a display device or the like.

[0002]

2. Description of the Related Art The applicant of the present invention is disclosed in JP-A-63-17421.
As described in Japanese Patent Laid-Open No. 6, a conductive transparent body suitable for use in a display device or the like is proposed. This conductive transparent body is formed by embedding a plurality of conductive wires in parallel in a base portion made of a transparent electrically insulating material so as not to short-circuit.

The connection between the conductive wire in the conductive transparent body and the power supply line on the power source side is partially peeled off by exposing the conductive wire partially by peeling off the base portion constituting the conductive transparent body. Then, the exposed surface of the conductive wire is subjected to electroless plating or electrolytic plating, and the exposed terminal of the conductive wire and the power supply side power supply wire are soldered.

[0004]

However, in such a conventional conductive transparent body, since it is necessary to plate the exposed terminals of the conductive wire, complicated equipment for plating is required. Is not easy.

Therefore, the applicant of the present application has previously applied for a display device in which a conductive wire in a conductive transparent body and a power supply wire on the power source side are simply and surely connected without using plating (Japanese Patent Application No. Hei 2). -70586). In this display device, a hole in which the end face of the conductive wire is exposed is provided in the base portion, the conductive paste is applied to the hole, the conductive pin is inserted, and the conductive paste and the conductive pin are soldered together. It has been configured. Further, in this display device, the conductive transparent body is supported by a pedestal, and the pedestal is configured by housing a power feeding unit connected to a power source in a case. The conductive pin of the conductive transparent body is connected to the power supply line of the power supply unit in the case by soldering, screwing, or the like.

However, in the above prior art, since the conductive wire of the conductive transparent body and the power supply wire on the power source side are connected via the conductive pin, the conductive paste and the solder, complicated equipment for plating is required. Although it is not necessary, it takes time and effort to connect the conductive wire and the power supply wire on the power supply side.

Further, when the conductive pin, the conductive paste and the solder are fixed in advance in the holes of the conductive transparent body,
Since it is difficult to remove the conductive transparent body from the power supply line after fixing the power supply line to the conductive pin, it is difficult to replace the conductive transparent body in after-maintenance and the like.

In view of the above problems, the present invention can save the labor of connecting the conductive wire of the conductive transparent body and the power supply line on the power source side, and at the same time, the conductive wire of the conductive transparent body can be removed. The purpose of the present invention is to make it possible to easily replace the conductive transparent body even after connecting to the power supply line.

[0009]

In order to achieve the above object, the conductive transparent body of the present invention is arranged in parallel on a base portion made of a transparent electrically insulating material so as not to short-circuit a plurality of conductive wires. In the conductive transparent body, a plurality of holes exposing the conductive wires are formed in the base portion, and the holes are arranged at a constant pitch in a direction orthogonal to the wiring direction of the conductive wires. In the conductive transparent body, the holes are arranged in two rows with the same pitch, and the holes in one row and the holes in the other row have a deviation of 1/2 of the pitch of the holes. The holes are arranged in four rows at the same pitch, and the holes in the first row and the holes in the second row have a deviation of ½ of the pitch of the holes and the third row from the end.

FIG. 1 is a plan view showing a conductive transparent body of the first embodiment, and FIG. 2 is a perspective view of an essential part of the conductive transparent body. The conductive transparent body 1 is an achromatic or chromatic transparent electrically insulating material. A plate-shaped base portion 11 made of (resin material, glass, etc.)
The conductive mesh 12 is embedded in the interior of the.

As shown in FIG. 2, the conductive mesh 12 has a plurality of conductive wires 1 which are parallel to each other so as not to short-circuit with each other.
3 is assembled in a net shape using the electrically insulated wire 14 as an assembly material.

The conductive wire 13 is formed of an ultrafine wire having a diameter or a width of 0.1 mm or less. The wire is a gold wire,
In addition to being formed from a metal element wire such as a silver wire, a zinc wire, and a stainless wire, it is formed by depositing or plating a metal on the surface of a resin element wire such as a polyester wire.

The electric insulation wire 14 is also formed of an ultrafine wire having a diameter or a width of 0.1 mm or less. The element wire is formed of resin element wire such as polyester wire and nylon wire.

That is, since the conductive transparent body 1 uses ultrafine wires as the conductive wires 13 and the electric insulating wires 14 which form the conductive mesh 12, the whole is achromatic or chromatic transparent. appear. The interval between the adjacent conductive lines 13 and the interval between the adjacent electrically insulating lines 14 are set in consideration of the transparency of the viewer. For example, when the conductive wire 13 and the electrically insulating wire 14 having a diameter of about 0.1 mm are used, it is preferable that the interval between the adjacent conductive wires 13 and the interval between the adjacent electrically insulating wires 14 are roughly set to about 10 mm or more, diameter
When the conductive wire 13 and the electrically insulated wire 14 having a size of about 20 μm are used, the distance between the adjacent electrically conductive wires 13 and the electrically insulated wire 14
It is preferable to set the interval of 1 to about 1 mm closely.

A plurality of holes 15 exposing the conductive wires 13 are formed at the edge of the base 11 of the conductive transparent body 1. The holes 15 are arranged at a constant pitch p in a direction orthogonal to the wiring direction of the conductive wire (direction of arrow y in FIG. 1),
They are arranged in two rows with the same pitch p. Also, this hole 1
5 has holes 15 in one row and holes 15 in the other row.
Has a deviation of 1/2 of the pitch p. That is, for example, when the pitch p of the holes 15 is 1/10 inch, the deviation between the holes 15 in one row and the holes 15 in the other row is 1/20.
It will be an inch deviation. Further, in order to expose the end face of at least one conductive wire 13 in the hole 15, it is easy to form the hole 15 having a diameter larger than the pitch p of the conductive wires 13.

That is, in the conductive transparent body 1 of the present embodiment, the plurality of conductive lines 13 are arranged in such a manner that they do not cross each other alternately. Therefore, one end of each conductive line 13 is positive or negative such as a display element or a lighting fixture. By connecting both terminals and connecting the other end of the conductive wire 13 connected to the display element or the lighting fixture to the power supply line on the power source side, it is possible to feed power to the display element, the lighting fixture or the like through the conductive wire 13. .

It can be done by inserting the terminal of the connector into. As the connector, an existing two-row multipole connector in which terminals are arranged in two rows and terminals in one row and terminals in the other row have a deviation of ½ of a pitch of the terminals can be used. By doing so, the plurality of conductive lines 13 can be connected together.

Further, since the holes 15 are arranged in two rows, the number of conductive wires 13 that can be energized can be almost doubled compared to the case where the holes 15 are arranged in one row.
