DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character-type license plate, and more particularly, to a license plate using an EL luminous body so as to emit a number or the like.

[0002]

2. Description of the Related Art Generally, a number plate is a metal plate on which predetermined characters (including numbers) are written. The number plate is attached to the front and rear portions of a vehicle, and at the same time, it is mounted on a vehicle at night. It is illuminated by a number light.

In order to improve the visibility at night,
As shown in FIGS. 5 and 6, an openable frame 2 attached to the entire surface of a flat case 1 is colored with a prescribed ground color and punched out a character 3 portion, and a transparent synthetic resin plate is applied to the character 3 portion. While fixing the attached license plate 4,
There are also cases in which an illuminating lamp 5 is provided inside the case 1, and a luminous license plate in which characters on the license plate 4 are illuminated by the illuminating lamp 5 at night or the like is also known.

As a light source of such a license plate, a light bulb is currently used. However, such a light bulb has a drawback that the character 3 cannot be uniformly illuminated unless a light dispersion plate or the like is used. E that emits light on the surface
A character-type license plate using an L illuminant has also been developed (Japanese Utility Model Laid-Open No. 58-41642, Japanese Utility Model Publication 7-5).
No. 2766). The luminous body 6 using such an EL luminous body as a light source has a structure in which a luminous body 61 is covered with a transparent waterproof resin sheet 62 as shown in FIG. Electrode terminal 6 for connecting to power supply
3 is extended, and has a structure protruding from the cover of the resin sheet 62. The conducting wire 7 is connected to the electrode terminal 63, and the conducting wire 7 is configured to be connected to the DC / AC converter 8.

[0005] However, light-emitting license plates of automobiles must exhibit light-emitting properties even under severe weather conditions such as typhoons and thunderstorms, and under conditions where vibrations are constantly applied, so that rust is generated by water and the like. Or a situation in which the light-emitting body itself is destroyed due to short-circuiting. Therefore, although a seal or the like is provided on the upper end surface of the case 1 to prevent water, dust and the like from entering the case 1, it cannot be completely prevented. For this reason, in the case of the light-emitting license plate having the above-described structure, water may enter the inside from the projecting portion of the electrode terminal 63 from the resin sheet 62. They may rust and be cut by vibration (see arrows).

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and in a character-type license plate using an EL luminous body, it is possible to prevent the terminal portion of the luminous body from being immersed in water or to prevent the connection portion from being rusted. An object of the present invention is to provide a durable light-emitting license plate.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of a principal part of a light-emitting license plate according to the present invention. FIG. FIG. 3 shows a bottom view of the lid.

As is apparent from these figures, the character-type license plate according to the present invention is provided with an opening / closing frame 2 attached to the entire surface of a flat case 1 and is colored in a prescribed ground color, and punches out three characters. A number plate 4 having a transparent synthetic resin plate adhered to the character 3 is fixed (see FIGS. 5 to 7), and an EL luminous body 6 is provided inside the case 1.
Is provided. The EL luminous body 6 has a structure in which a luminous body 61 is covered with a transparent waterproof resin sheet 62, and an electrode terminal 63 for connecting to an AC power source is extended from the luminous body 61, and the EL resin 6 is made of resin. The structure protrudes from the cover of the sheet 62. And this electrode terminal 63
Is connected to a DC / AC converter 8 via a watertight outlet C.

In the present invention, as shown in FIGS. 1 and 2, the EL luminous body 6 is mounted on a transparent waterproof film 9, and the waterproof film 9 is provided on the bottom surface of the EL luminous body 6. It is laid and fixed inside the case 1 so as to cover it.
The left end portion of the waterproof film 9 has an engagement portion 91 formed in a bag shape, and is engaged by inserting one end portion of the EL luminous body 6 into the engagement portion 91 in a bag shape. It is possible to stop.

On the other hand, at the end opposite to the above, as shown in FIG. 3, the electrode terminal 63 protruding from the EL luminous body 6 and the connection with the conductor 7 are covered, and an elastic contact portion 92 for adhesion is provided. Are formed.

Further, a ridge 93 serving as a male portion of the fastener F is formed at the opposite end. The protruding ridges 93 are formed so as to extend in the width direction of the waterproof film 9 from the side of the contact portion 92, bend, and extend in the longitudinal direction.

FIG. 3 is a bottom view of the lid 10 fixed on the opposite end by a fastener F.
In the same manner as the above-mentioned opposite end portion, the bottom surface of the contact hole 0 is provided with an electrode terminal 63 and a contact portion 101 for adhering to the connection portion between the electrode terminal 63 and the conducting wire 7 and the fastener F
A concave portion 102 serving as a female portion is formed at a position corresponding to the ridge 93 of FIG. That is, similarly to the ridges 93, the ridges 93 are formed so as to extend in the width direction from the side portions of the contact portion 101 and further extend in the longitudinal direction.

With such a structure, the above E
One end of the L illuminator 6 is engaged with the engaging portion 91 of the waterproof film 9.
After the EL luminous body 6 is placed on the waterproof film 9, the cover 10 is put on the opposite end, and pressed along the fastener F, so that the projection 9 of the fastener F is formed.
3 and the recess 101 are fitted, and both are fixed.

At this time, the lid 10 and the waterproof film 9
Since water or the like entering from the joint with the EL element is blocked by the fastener F, the joint with the EL luminous body 6, the electrode terminal 63, and the conducting wire 7 can be extremely well waterproofed and dust-proof.

According to the present invention, the converter 8 and the EL
The connection of the luminous body 6 in FIG. The watertight outlet C may be further housed in a commonly used watertight container.

As described above, according to the present invention, the waterproof film 9 is laid in the case 1 and the waterproof film 9
The EL luminous body 6 is laid thereon, and the electrode end 63 is covered with a lid having a close contact portion 93 and a close contact portion 101.
, Water and dust from water, dust and the like from the bottom of the case 1 can be provided, and the electrode terminals 6
3. Waterproofing, dustproofing, rustproofing, etc. from the connection part are possible,
It is possible to significantly improve the durability. further,
As described above, since the connection between the converter 8 and the EL luminous body 6 shown in FIG.
When the light-emitting body 6 breaks down, it can be easily replaced simply by removing the outlet C, peeling off the lid 10 and pulling it out from the engaging portion, which is extremely practical.

[0019]

As described above, according to the light-emitting license plate of the present invention, since the electrode terminal portions of the EL luminous body are covered with the waterproof film and the waterproof lid, water permeates into the luminous body. There is also an advantage that the connection portion between the terminal and the conducting wire can be prevented from being deteriorated by water, dust and the like, and a light-emitting license plate having good durability can be obtained.
