They are designed to face each other at a predetermined position.

Reference numeral 7 denotes an object to be connected, such as a flat cable, and a connection pad (conductor portion for connection) 8 is provided at the tip end 7a of the cable.

This connection pad 8 has been subjected to surface treatment with gold, rhodium, solder, etc. in advance.

The distal end portion 7a of the flat cable 7 is inserted into the guide body 4 so that the opposite side of the connection pad 8 contacts the upper surface of the housing 1, and is fixed thereto via an adhesive 9.

Further, the other end side 7b of the flat cable 7 is folded back toward the rear side of the housing 1, and is fixed by a fixing portion 10 provided at the rear of the upper surface of the housing 1.

Reference numeral 11 denotes a plate spring made of copper, phosphor bronze, bronze, nickel silver, etc., which is provided on the lower surface of the two opposing surfaces in the housing 1, and is connected to the opening of the housing 1 between it and the connection pad 8. It gradually expands towards the edges.

It has a shape that forms a gap, and when the display panel 3 is inserted into the housing 1, the display panel 3 is pushed upward by the elastic force of the leaf spring 11, and its connecting conductor part is connected to the flat cable 7. It is adapted to come into pressure contact with the connection pad 8.

With the above configuration, one end 3a of the display panel 3 is inserted into the gap between the connection pad 8 and the plate spring 11 in the housing 1 through the opening 2 of the housing 1 against the elastic force of the plate spring 11. By fitting the small hole 6 into the projection 5, the terminal of the display panel 3 and the connection pad 8 of the flat cable 7 are aligned, and at the same time the leaf spring 11
The terminals of the display panel 3 are pressurized and connected to the connection pads 8 of the flat cable 7 by the elastic force of the terminals, thereby establishing mutual connection.

On the other hand, in order to disconnect the display panel 3 and the flat cable 7, the display panel 3 is pushed down into the housing 1 against the elastic force of the leaf spring 11, and the small hole 6 and the protrusion are removed. It is sufficient to pull it out from inside the housing 1 in a state in which the fitting with the part 5 is removed.

As described above, the present invention has the advantage of being excellent in attaching and detaching the display panel and improving alignment accuracy and workability.

FIG. 3 shows a second embodiment of the present invention.

In this embodiment, a sharp-pointed protrusion 20 that can be connected to a commercially available connector in the same way as a terminal on a conventional printed circuit board is formed on the upper rear surface of the housing 1.
The lower surface of b is fixed to the upper surface of the housing 1 and the protrusion 20 with an adhesive 21, and a connection pad 22 is provided on the upper surface of the flat cable 7, but the other configuration is the same as that of the first embodiment. It is.

According to this embodiment, the display panel 3 and a commercially available connector attached to another electrical device can be easily connected via the housing 1. Similar to the example.

FIG. 4 shows a third embodiment of the present invention.

In this embodiment, when the display panel 3 is attached to and detached from the housing 1, the inside of the housing 1 is pushed upward and downward to prevent contact between the upper and lower surfaces of the display panel 3 and other parts in the housing 1, thereby preventing mutual wear. It is designed to prevent this.

That is, 30 is a cam for pushing and spreading supported in the housing 1, 31 is a compression spring of the housing 1, and 32 is a rotor attached to the outer surface of the housing 1, and the rotor 32 is rotated by a predetermined angle. By doing so, the cam 30 is rotated by a predetermined angle via a connection mechanism (not shown), and the inside of the housing 1 is pushed and expanded in the vertical direction against the tension of the compression spring 31.

Other aspects of the structure, operation, and effects are the same as those of the previous embodiment.
