FIG. 4 shows another application example of the connection terminal according to the above-described embodiment. In the above-described embodiment, the column portion 12 is formed from the side of the film substrate A where the conductive pattern a is not formed. However, in this embodiment, the pillar portion 12 is inserted from the side where the conductive pattern a is formed. In this embodiment, the flange portion 11 comes into contact with the conductive pattern a. .

FIG. 5 shows a film-shaped substrate A in which conductive patterns a, a are formed on both surfaces. Similar to the above-described embodiment, the pillars 12 are formed by small holes formed in the conductive patterns a, a. The ring 2 and the flange 11 come into contact with the conductive patterns a, a, and the conductive pattern a is short-circuited by the pillar 12 to form a through hole. Become.

FIGS. 6A to 6C show another embodiment of the fitting portion 12a. In the above-described embodiment, the fitting portion 12a is formed in an iris knurl. FIG. And a thin portion 2a is formed on the inner surface of the ring 2 so that it can be elastically fitted to the bulging portion 12b.

FIG. 6B shows that the pillar portion 21 is formed in a prismatic shape, a drum-shaped bulging portion 12b is formed in the fitting portion 21a, and a through hole 12b 'is formed in this portion to provide elasticity. In addition, thin portions 2a are formed at four corners of the inner surface of the quadrangular ring 2 so as to be elastically fitted to the bulging portion 2b. Further, FIG. 6C shows the column portion 12 of FIG. 6B as a column, and the other shapes are the same.

FIGS. 7A to 7D show still another embodiment of the connection terminal according to the present invention. In the above-mentioned embodiment, the flange 11 is formed at the base end of the column 12, whereas Is formed at a position distant from the base end of the pillar 12, and the fitting portion 12 a is formed at a position close to the base end of the pillar 12. Since the shapes of the fitting portions 12a and 12b are the same as those in FIGS. 1 and 6, the same reference numerals are given and the description is omitted.

The connection terminal thus configured is fitted into a small hole formed in the conductive pattern a of the film-like substrate A by the fitting portion 1.
2a is inserted from the side of the conductive pattern a as shown in FIG. 8, or from the opposite side as shown in FIG. The connection terminal can be fixed to the film-shaped substrate A by press-fitting the ring 2 into the fitted portion 12a as in FIGS.

In each of the above-described embodiments, the case where the connection terminals are fixed to the film-like substrate A individually has been described. In the embodiment described below, at least two connection terminals are used. The case where they are fixed at the same time is shown.

(A) is press-fitted into each hole of the rectangular block 3 made of synthetic resin in which at least two holes are formed. The openings of the block 3 are opened so as to match the intervals of the small holes formed in the conductive pattern a of the film-like substrate A.

Then, the fitting portion 12a of the pin 1 fixed to the block 3 is inserted into the small hole of the film-like substrate A, and then the ring 2 is pressed into the fitting portion 12a projecting from the film-like substrate A. And fit. Thus, the two pins 1 can be easily attached to the film-like substrate A.

In the embodiments shown in FIGS. 11 and 12, the rings 2 are press-fitted and fixed to the respective fitting portions 12a projecting from the film-like substrate A. However, FIGS. 13 and 14 show a case where the ring 2 is fixed by the second block 4 instead of the ring 2 at the same time.

That is, the second block 4 is press-fitted and fitted into the fitting portion 12a projecting from the back surface of the film-like substrate A, so that the film-like substrate A
Are held, and in this state, the flange portion 11 comes into contact with the conductive pattern a so that power can be supplied.

FIGS. 15 and 16 show a case where the film 3 is fixed to the film substrate A by the block 3 using at least two pins 1 shown in FIGS. 1 and 6 (shown in FIG. 1). That is, the pillar portion 12 is inserted from the conductive pattern a side of the film-like substrate A, and the block 3 is pressed into and fixed to the fitting portion 12a projecting from the upper surface of the film-like substrate A. Thereby, the flange portion 11 comes into contact with the conductive pattern a of the film-shaped substrate A, so that power can be supplied.

The column 2 in the above-described embodiment
Although the tip of 1 is shown as being linear, the tip may be bent into an L-shape, and the shape of the fitting portion 12a is not limited to the above-described embodiment. Any shape may be used as long as it does not easily come off the ring 2 or the block 3.

[0027]

As described above, according to the present invention, a pin having a flange portion and a fitting portion is inserted into a small hole of a conductive pattern on a film-like substrate, and a ring is press-fitted and fixed to the fitting portion. Thus, the conductive pattern and the pins are electrically connected, so that power can be easily supplied to the film-shaped substrate by connecting a lead wire from a power supply to the pins, and therefore, the structure is simple. Connection terminals can be configured at low cost.

When conductive patterns are present on both surfaces of the film-like substrate, the conductive patterns on both surfaces are connected by the pins by the flanges of the pins and the ring, and therefore can also serve as through holes. it can.

Further, by using an insulating block having a plurality of holes in place of the ring, two or more pins can be integrated in one block and can be simultaneously attached to the film-like substrate. It is advantageous in that the workability is good and the pins can be securely fixed to the film substrate.
