Abstract

PURPOSE:To increase the strength of attachment of a display element to a transparent body and facilitate replacement of the display element by inserting the display element into a hole in the transparent body by way of a conductor plate. CONSTITUTION:A hole 25 is drilled in each of two connection pieces 20A and 20B made of L shaped metallic conductor plates so that lead terminals 6A and 6B of an LED 6 are inserted. Lead terminals 6A and 6B are respectively inserted in the holes 25 and secured to the connection pieces 20A and 20B by bending or soldering. Drilling a hole 19 for exposing the ends of two conductive wires 15 in a base portion 11, an LED to which the connection pieces 20A and 20B are secured is inserted in the hole 19. Both connection pieces 20A and 20B are inserted so that each of them comes in contact with only one conductor wire 15 exposed in the inner wall of the hole 19. This increases the strength of attaching the display element to a transparent body and facilitates replacement of the display elements.

This conductive transparent body has a base portion made of a transparent electrically insulating material, and a plurality of conductive wires arranged side by side so as not to short-circuit each other.

When attempting to install an LED inside a transparent body, bend the two lead terminals of the LED along the LED, and drill a hole in the base of the transparent body into which they can be inserted.
The LED is inserted into the chain hole and its lead terminal is brought into contact with the conductive wire exposed inside the hole.

[Problem to be solved by the invention] However, the prior art has the following problems (1) and (2).

■The fixation of the LED in the hole of the transparent body is not strong. Therefore, there is a risk that the contact between the LED and the conductive wire may be broken due to vibration, resulting in poor continuity.

(2) After inserting the LED into the hole, it may be possible to pour resin into the hole around the LED and fix it, but in that case, the LED cannot be replaced.

[Means for Solving the Problems] The present invention as set forth in claim 1 provides an electrically conductive transparent body comprising a base portion made of a transparent electrically insulating material and a plurality of conductive wires arranged side by side so as not to short-circuit each other. In the connection structure, holes are provided in the base portion through which end surfaces of at least two electrically separated conductive wires are exposed at different positions,
2 fixed to each of the two gate terminals of the display element.
The conductive plate is inserted into the hole so as to be electrically connected to only one conductive wire of each of the conductive plates.

According to a second aspect of the present invention, a conductive paste is applied to the inner wall of the hole, and the conductive plate and the conductive wire are electrically connected through the conductive paste.

[Action] According to the present invention as set forth in claim 1, there are the following effects (1) and (2).

(2) Since the display element is inserted into the hole in the transparent body via a conductive plate with a wide area, it can maintain strong mounting strength without losing contact with the conductive wire even in the event of vibrations.

(2) The display element is removable from the hole and can be easily replaced.

According to the present invention as set forth in claim 2, there is the following effect (2).

■Continuity between the conductive plate and the conductive wire can be ensured by using the conductive paste.

[Example] Fig. 1 is a schematic diagram showing a display side connection structure according to the present invention, Fig. 2 is a schematic diagram showing a power supply side connection structure, Fig. 3 is a plan view showing a conductive transparent body, and Fig. 4 is a schematic diagram showing a power supply side connection structure according to the present invention. An enlarged perspective view of the main parts in Figure 2,
FIG. 5 is a perspective view showing the display device.

As shown in FIG. 5, the display device 1 includes a conductive transparent body 3 supported on a leg part 2, a power supply part 4 built into the leg part 2, and a display part 5 in the transparent body 3.

At this time, as shown in FIG. 3, the display device 1 has two conductive power supply side connections as described below at the lower ends of the two conductive wires 15 in the base portion 11 of the conductive transparent body 3. At the same time as the tool 18 is installed, two conductive display-side connectors 20 as described later are installed in the intermediate portions of the two conductive wires 15. Then, each of the two power supply lines extending from the power supply section 4 is connected to the reconnection tool 18, and the L is connected to the reconnection tool 20.
By connecting the two lead terminals 6A and 6B of the ED6, the power supply unit 4, one power supply side connector 18, one conductive wire 5, one display side connector 20, the LED 6, and the other display side A closed circuit is formed around the connector 20, the other conductive wire 15, and the other power supply side connector 18, and the LED 6 can be turned on.

However, the conductive transparent body 3 has a conductive mesh 12 embedded inside a plate-shaped base portion 11 made of an achromatic or chromatic transparent electric insulating material (resin material, glass, etc.).

As shown in FIG. 4, the conductive mesh 12 is formed by incorporating a plurality of conductive wires 15 parallel to each other so as not to short-circuit each other into a net shape using electrically insulated wires 16 as members.

The conductive wire 15 is formed of an ultrafine wire with a diameter or width of 0.1 mm or less. The above-mentioned wires are formed from metal wires such as gold wire, silver wire, copper wire, zinc wire, stainless steel wire, etc., or by vapor-depositing or plating metal on the surface of resin wires such as polyester wire. be done.

The electrically insulated wire 16 is also formed of an ultrafine strand with a diameter or width of 0.1 mm or less. The wire is formed of a resin wire such as a polyester wire or a nylon wire.

That is, since the conductive transparent body 3 uses ultrafine strands as the conductive wires 15 and the electrically insulated wires 16 constituting the conductive mesh 12, the conductive transparent body 3 can be seen as an achromatic or chromatic transparent body as a whole. At this time, the intervals between adjacent conductive wires 15 and the intervals between adjacent electrically insulated wires 16 are set in consideration of the viewer's sense of transparency.

When using conductive wires 15 and electrically insulated wires 16 of approximately 0 μm, the intervals between adjacent conductive wires 15 and the intervals between adjacent electrically insulated wires 16 can be set closely to approximately 1 mm.

Since the conductive transparent body 3 has a plurality of conductive wires 15 disposed so as not to cross each other, each conductive wire 15 can be electrically separated into two or more parts. Therefore, the two sorting terminals 6A and 6B of the LED 6 can be connected to each conductive wire 15 in the middle part of the transparent base portion 11, thereby supplying power to the LED 6.

In addition, since the conductive transparent body 3 has a conductive mesh 12 made of electrically insulated wires 16 disposed inside or on the surface of the base portion 11, each conductive wire 15 can be reliably and easily spaced at a constant interval. It can be kept and placed.

(2) A connector 18 made of cylindrical conductive rubber having an outer diameter smaller than the inner diameter of the hole 17 is inserted into the hole 17 (see FIG. 2(A)).

(3) Insert the connecting pin 22 into the center of the connecting tool 18 (
(See Figures 2 (B) and (C)).

At this time, the diameter of the connecting pin 22 is set to be larger than the difference between the inner diameter of the hole 17 and the outer diameter of the connecting tool 18, and as a result, the outer diameter of the connecting tool 18 is expanded and the connecting tool 18 is inserted into the hole 17. Press it against the exposed conductive wire 15.

(4) The connecting pin 22 inserted into the connecting tool 18 is used to solder the terminal 24 of the external conductor 23, connect the connector, and the socket I.
etc. will be maintained.

Note that the shape of the conductive rubber constituting the connector 18 is not limited to a cylinder, and by using a cylinder, a cylinder cut in half, etc., the connection pin 22 can be easily inserted.
