どで行われる。Background technology Electroluminescent lamps (EL lamps, EL panels) used to display characters, numbers, symbols, etc. on watches, electronic desktop calculators, and various measuring instruments have a light-emitting element sealed in a hard material such as enamel. Although there are some robust types, the most commonly used are flexible types in which the emitting element is sealed with a flexible resin outer film. This latter type has features such as being lightweight, inexpensive, and thin. Examples of its conventional structure are explained in Figs. It consists of two transparent resin outer films that are fixed together. The emitting element 1 has a flexible flat plate shape, for example, a transparent thin flexible organic film 4 is used as a base, a transparent electrode 5 such as Sno 2 is deposited on one side, and a material such as cyanated cellulose is coated on the transparent electrode 5. A light - emitting layer 6 is formed by applying a powdered phosphor such as ZnS, which is released by applying an electric field, to the resin. This structure has a structure in which a back electrode 8 is formed on the insulating layer 7 by Al vapor deposition or the like. 9 and 1
0 is a mesh-shaped electrode lead wire whose one end is electrically connected to each of the upper and lower electrodes 5 and 8 of the light emitting element 1 and extends outward, and 11 and 12 are the lead-out ends of each electrode lead wire 9 and 10. A resin-coated wire is used as an external lead wire that is electrically and mechanically connected with solders 13 and 14 and extends to the outside. In the assembly of such an electroluminescent lamp, electrode lead wires 9 and 10 are connected to the light emitting element 1.
After soldering the external lead wires 11 and 12 to the respective lead wires 9 and 10, the light emitting element 1 is attached to two upper and lower outer skin films, including the connection parts of the lead wires 9, 11, 10, and 12. 2 and 3 in a sandwich style, and heat-pressing and sealing the periphery of each outer film 2 and 3, or with the tips of the electrode lead wires 9 and 10 exposed, the light emitting element 1
After sealing with the outer skin films 2 and 3, external lead wires 11 and 1 are attached to the tips of the electrode lead wires 9 and 10.
2 is soldered, and then the soldered portion is sealed by partially sealing the outer skin films 2 and 3.

起すことが多々ある。 By the way, when hot pressing the outer skin films 2 and 3 assembled as described above, it is necessary to position each of the external lead wires 11 and 12 so that they do not shift.
This is done by temporarily fixing it to one of the inner surfaces of 3 with adhesive tape or the like. However, such temporary fixing means is labor-intensive and has little implementation effect, making automatic assembly difficult. Furthermore, the ends of the external lead wires 11 and 12 are sealed and fixed with the respective outer skin films 2 and 3, but the external lead wires 11 and 12 are relatively thick to obtain mechanical strength, and therefore, the external lead wires 11 and 12 are relatively thick to obtain mechanical strength.
The sealing properties of the outer skin films 2 and 3 are poor at the parts 1 and 12, and the external lead wires 11 and 12 tend to wobble.
The solders 13 and 14 often come off, causing a so-called open defect.

減る。 The present invention is characterized in that each end of the electrode lead wire and the external lead wire are overlapped, and the overlapping portion is fixed by caulking with a fastener inserted into the inner surface of one of the outer skin films. By caulking the fastening tool, both lead wires are firmly connected mechanically and electrically connected. The fastening tool may be made of metal, resin, or the like, and its material does not matter; however, it is preferably made of metal in order to improve the electrical connection and mechanical strength of both lead wires. According to the present invention, there is no need to solder both lead wires, and by positioning the lead wires with a stopper, assembly becomes easier and the number of assembly steps is reduced.

る。 The electroluminescent lamp according to the present invention is assembled in the following manner. First, the electrode lead wires 9 and 10 are attached to the light emitting element 1, and then this is positioned and placed on a single outer skin film 3. Next, as shown in FIG.
External lead wires 11 and 12 corresponding to each tip of 0
Position the ends of the two in a fixed position and overlap them, and pass the overlapping portions through the barbed strips 15', 1 of the stoppers 15, 16.
6' firmly into the outer skin film 3 to insert it. As a result, each lead wire 9, 11 and 10, 12
The overlapping portions are caulked and fixed to the outer skin film 3 by the respective fasteners 15 and 16, and the electric connection is firmly established by the caulking. After that, another outer skin film 2 is placed on the above-mentioned outer skin film 3, and the peripheral edges of both films 2 and 3 are sealed by hot pressing. During this heat press work, each lead wire 9, 11, 10, 1
2 is temporarily fixed with the fixing tools 15 and 16, so there is no fear of displacement, and automation is facilitated. Also, by sealing the outer skin films 2 and 3, the stopper 1
5 and 16 are prevented from coming off and are firmly fixed.
When an external force is applied to the external leads 11 and 12 after assembly, this external force is transmitted to the stoppers 15 and 16, but the stoppers 15 and 16 are stable because they are inserted into the outer skin film 3 and fixed. Therefore, the connection state of each lead 9, 11, 10, 12 will not be damaged by external force, and open defects will be drastically reduced.

A strip 17' inserted into the outer skin film 3 may be provided, and the center portion of the lower surface may have a wavy surface 17'' that bites into the lead wire. It is desirable to form a return that prevents it from coming out once it is inserted into the outer skin film.
