Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of connection terminals for connecting a flexible substrate to an electroluminescence substrate formed on a PET film or connecting electrodes.

[0002]

2. Description of the Related Art Conventionally, when electrodes of an electroluminescent substrate and a flexible substrate are connected to each other or an external terminal is connected from an electrode of an electroluminescence, a conductive adhesive is applied to each electrode and each other is connected to each other. Connected and used.

[0003]

Conventionally, when connecting a substrate for electroluminescence, which is considered to be mechanically and structurally weak, to another electrode of a flexible substrate, for example, a conductive adhesive is applied to one or both electrodes. And electrically and mechanically connected to each other. Also, when a metal external terminal is connected to the electroluminescent substrate electrode, a conductive adhesive is similarly used. When using a conductive adhesive, at least three steps are required: coating, laminating, and drying steps. It is difficult to mechanize, and because the mechanical strength of the connection is weak, it can be used in places where vibration is applied. Considerable care was required in handling the external terminals.

[0004]

According to the present invention, there are provided a metal plate having several sharp metal projections in order to enable a mechanically strong connection, to have a high connection reliability, and to reduce the thickness. Was provided in a ring shape.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The connection terminal of the present invention is provided with several claws protruding upward at the center or the outer periphery of a substantially square or circular base, and if necessary, generally has an elongated external electrode. The structure provided in the base part was adopted.

[0006]

Embodiment 1 Hereinafter, Embodiment 1 of the present invention will be described with reference to FIGS. 1, 2 and 5. FIG. At least two claw portions (2) whose ends are thinner than their roots in a substantially concentric manner at the approximate center or outer periphery of a substantially circular or rectangular base portion (1) made mainly of metal. In (1), the base member (1) and the same member are provided integrally in a substantially vertical direction. In use, the claw (2) of the terminal (6) is pierced from one side with the electroluminescent substrate electrode (5) and the flexible substrate electrode (8) facing each other, and the claw (2)
The flexible substrate electrode (8) and the electroluminescent substrate electrode (5) are pressurized by bending the tip of the substrate outward or inward, and are mechanically and electrically connected to each other. At this time, the claw portion (2) and the base portion (1) may be used after being subjected to insulation treatment, or may be used after being subjected to metal plating. The electrodes may be used back to back.

In the embodiments shown in FIGS. 3, 4, 6, 7 and 8, a plate-like external electrode portion (3) is formed mainly from a part of the base portion (1).
Is formed and provided. In use, the electroluminescent substrate electrode (5) and the flexible substrate electrode (8) are back-to-back with each other, and the claws (2) of the terminal (6) are pierced from one side with each electrode visible outside. The tip of the rear claw portion (2) is bent outward or inward to press the electrodes of each substrate and mechanically and electrically connect each other. The external electrode portion (3) is used for connection and inspection with other parts. Used. Alternatively, the terminal (6) is electrically and mechanically connected to the electroluminescent electrode (5) by piercing the claw (2) from either side of the electroluminescent substrate electrode (5) and bending the same, and externally. Another member is connected to the protruding external electrode portion (3), or used for inspection or the like. At this time, the electroluminescent substrate electrode (5) and the flexible substrate electrode (8) may be used while facing each other.

[0008]

The present invention is embodied in the form described above, and has the following effects.

Since the connection terminals are made of metal and the electrodes are mechanically pressed between the permanently deformed claw and the base, the connection strength is high, and the electrical and mechanical reliability is high.

Since the step of penetrating the claw portion into the substrate and the step of pressurizing are simple operations, mechanization is easy and productivity is high.

By changing the thickness of the plate or adjusting the number of claws, it is easy to cope with a change in the thickness, the number of connection portions, and a change in the electrode pitch.
