Description

[Detailed Description of the Invention] The present invention relates to an improvement of a device for connecting a display panel and a flexible printed circuit board (hereinafter referred to as FPC).

Conventionally, this type of connection device, as shown in FIG.
Insulator 3 with built-in rubber 4 to prevent the FPC from shifting
Cover it with FPC1, and insulator 3 with spring socket 2.
The panel is sandwiched between the panel and the spring pressure of the clip causes the rubber to elastically deform and the connection is fixed.However, with this method, the contact between the plug and the FPC tends to come into contact during work, and since the panel is made of glass, the spring The problem was that the clip would slip, become loose, and become loose.

In order to improve these drawbacks, the present invention has the structure shown below.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

In FIG. 2A, the connection part 51 of the display panel 5
Apply double-sided adhesive tape 8 from the tip of the connector to the area where the spring clip 6 is applied on the back side (1'), position the FPCI to the plug, and then temporarily secure it.

Cover the temporarily fixed FPC and the adhesive tape on the back side with an insulating rubber 9 formed into a U-shape or bent from the direction of arrow A, and use a spring clip 6 formed by bending a spring material using a bar 11 as shown in the diagram. After the bar 11 is inserted into the insulating rubber and fixed, the bar 11 is removed.

The contact between the plug portion 51 and the FPC 1 is achieved by elastically deforming the insulating rubber 9 in the portion sandwiched between the R portions 10 by the spring pressure of the spring clip, thereby obtaining uniform and stable contact over the entire surface.

In addition, the bent end of the R portion 10 of the spring clip is left open so that the bar 11 can be inserted from the horizontal or vertical direction only during work, so that the mounting density after connection and fixation can be improved. The portion 7 is a projection having spring properties attached to the inner surface of the spring clip 6 to prevent the insulating rubber from loosening.

In addition, if the spring clip 6 is not long, the spring pressure will increase, which will impair work efficiency, so it is better to use clips of an appropriate size without leaving any space between them, and the insulating rubber should be manufactured in long clips. Lay it out and cut it according to the size of the panel.

FIG. 3 shows a perspective view of a device in which the present invention is implemented.

Figures 4 and 5 show the above insulating rubber 9 replaced with insulating plastic 12. This allows the spring pressure of the spring clip to be applied to the FPC in a range larger than the clip width, reducing the amount of clip used. It can be done less.

In FIG. 5, the insulating plastic 12 is inserted into the panel from the direction of arrow B, and fixed by inserting spring clips into grooves 14 provided at regular intervals in the same manner as described above.

Since the present invention is configured as described above, it has the following advantages.

(b) By pasting double-sided adhesive tape on the display panel in advance, the FPC can be easily positioned on the panel, and at the same time it can be temporarily fixed, which prevents the contacts from shifting, which tends to occur during connection work as with conventional products. Good workability.

(b) Since the double-sided adhesive tape is pasted to the insulating rubber or insulating plastic presser on the back of the panel, the insulator can be firmly fixed and will not easily come off the panel.
