DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the embodiments shown in the drawings. 1 and 2 show an embodiment of a strip-shaped electric wire according to the present invention. In this embodiment, the two conductors 2 of the strip-shaped electric wire 1 are formed by flatly crushing a braided wire that is braided in a tubular shape. These conducting wires 2 are covered with a silicone resin powder (not shown) over the entire circumference and the entire length thereof and covered with a flexible belt-like electric insulator 3 made of vinyl chloride, polypropylene, rubber or the like. Therefore, the silicone resin powder is interposed between the conductor 2 and the insulator 3. Specifically, as shown in FIG. 1, for example, as shown in FIG. 1, the electric wire 3 is covered with the electric insulator 3 by using two flexible electric insulators 3a and 3b made of vinyl chloride, polypropylene, rubber or the like. Is sandwiched from both sides, and these two electrical insulators 3a and 3b are made into an integral electrical insulator 3 by, for example, ultrasonic welding or thermocompression bonding.

The strip-shaped electric wire 1 includes a conductor 2 and an electric insulator 3.
Since the silicone resin powder having a lubricating function is interposed between and, the conductive wire 2 and the electrical insulator 3 can easily move with respect to each other, and can be bent in the width direction as well, as shown in FIG. Can be extended so as to draw a desired curve on a desired plane. Although FIG. 3 shows an example in which the strip-shaped electric wire 1 is bent in the width direction so as to draw a circle on a plane, the strip-shaped electric wire 1 is of course not only circular on the plane but also corrugated or U-shaped. It can be bent so as to draw various curves such as an arch, an S and the like.

In the above embodiment, one strip-shaped electric wire 1 has two
Although the case where the conductor 2 is provided is shown, in the present invention, an arbitrary number of conductors can be provided on one strip-shaped electric wire 1.

Further, in the above-mentioned embodiment, a flat braided braided wire woven into a tubular shape is used as the conductive wire 2, but other kinds of conductive wire can be used in the present invention. Is. However, when the conductor wire 2 obtained by flatly crushing the braided wire braided into a tubular shape is used as in the above-described embodiment, the band-shaped electric wire 1 can be more easily bent due to the expansion and contraction of the braided wire.

Further, in the above embodiment, the silicone resin powder is used as the lubricating substance to be interposed between the conductor and the electric insulator, but in the present invention, the lubricating substance is fluororesin powder, molybdenum disulfide. It is also possible to use other types of powdery lubricating substances such as powders, and liquid lubricating substances such as various lubricating oils.

One end side of each socket terminal 5b is accommodated in the socket body 5a, and the other end side of each socket terminal 5b projects from the bottom of the socket body 5a to the outside of the body 5a. The bottom of the socket body 5a is fixed to the front surface of the insulator 3 at a position corresponding to each conductive wire exposure hole 4 by ultrasonic welding or adhesion. The portion of the socket terminal 5b that protrudes to the outside of the socket body 5a penetrates the insulator 3 from the front side inside the two conductors 2 and is also bent outward and stacked on the conductor 2, and further the conductor 2 Is soldered to (6
Indicates this soldering part). After the soldering, the soldering portion 6 and its surroundings are covered with an insulating piece 7 made of an electrically insulating soft plastic in order to ensure insulation from the outside.

Reference numeral 8 denotes a light bulb mounting body made of an electrically insulating plastic, and this light bulb mounting body 8 has a substantially hollow cylindrical shape with a bottom. A bottom side of an incandescent light bulb 9 is detachably fitted to the light bulb mounting body 8, and a pair of lead wires 9a of the light bulb 9 penetrates the bottom portion of the light bulb mounting body 8 and also a light bulb mounting body. It is folded back along the side surface of 8.

On the inner peripheral surface of the socket body 5a, the light bulb mounting body 8 is detachably fitted with the light bulb 9 attached thereto as described above.

As shown in FIG. 5, the strip-shaped electric wire 1 is bent in the width direction so as to draw a circle on a plane. Here, the conductor wire exposure hole 4 may be opened before bending the band-shaped electric wire 1 or may be opened after bending. Also,
After the strip-shaped electric wire 1 is bent in the width direction, the bottom portion of the socket 5 is fixed to the insulator 3 of the strip-shaped electric wire 1 by ultrasonic welding or adhesion as described above, and the lead wire 9a of the light bulb 9 is connected to the conductive wire 2.
When soldered to, the strip-shaped electric wire 1 is restrained by this, and the curved state of the strip-shaped electric wire 1 in the width direction can be maintained.

In this light emitting device, the lead wire 2 is connected to a power source, and the lead wire 2, the socket terminal 5b, and the lead wire 9 are connected.
If an electric current is applied to each of the light bulbs 9 through a, these light bulbs 9 can be turned on. Further, since the strip-shaped electric wire 1 can be extended so as to draw a desired curve on a desired plane, the decorative effect can be remarkably enhanced.

FIG. 8 shows another example of the band-shaped light emitting device constructed by using the band-shaped electric wire 1 shown in FIGS. In this device, the conductor wire exposure hole 10 is provided on the front surface of the insulator 3. The socket 11 made of plastic has a substantially cylindrical shape, and the bottom of the socket 11 is placed on the surface of the insulator 3 so that the lead wire exposure holes 10 are located in the socket 11 by ultrasonic welding or adhesion.

In this embodiment, when the light bulb mounting body 12 is fitted into the inner circumference of the socket 11, the tip end of each contact terminal 13 is brought into contact with the conductor wire 2 of the electric wire 1 in the conductor wire exposure hole 10. Further, by pulling the light bulb mounting body 12 in the direction away from the electric wire 1, the light bulb mounting body 12 can be easily pulled out together with the light bulb 9 from the socket 11.

In this embodiment, the contact terminal 13 is elastically in contact with the conductor wire 2 and is not fixed, so that the socket 11 restrains the band-shaped wire 1 less. While the fixing of the socket 11 to the insulator 3 of the strip-shaped electric wire 1 is performed in the factory, the work of bending the strip-shaped electric wire 1 in the width direction is suitable when performed on site.
