Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a decorative lighting device for use in decoration, advertising, and the like.

(Prior Art) A conventional decorative lighting device of this type is made by covering two parallel conductive wires with synthetic resin, as described in Japanese Utility Model Application Publication No. 58-55384. In a decorative lighting device in which a large number of socket bodies are electrically and mechanically connected and fixed to a flat cable, and wedge light bulbs are attached to the socket bodies, the socket bodies are welded to the conductive wires of the flat cable. The bottom part is fixed to the surface of the flat cable with adhesive and a wedge light bulb is attached to the top part to form a strip-shaped decorative lighting device. Make a welding notch on the back side of the flat cable to expose the conductive wire, turn the connecting terminal inserted from the surface of the flat cable to the back side of the conductive wire, weld and connect it, and then insert the welding notch into the insulating resin It was covered with

(Problem to be solved by the invention) In the conventional device as described above, the socket body is fixed to the flat cable using adhesive, so it takes a long time for the adhesive to harden, which increases the assembly time. In addition to being long, many flat cables are made of vinyl chloride resin, and it is difficult to find a suitable adhesive to firmly bond the socket body to this resin material. There was a problem that adhesion could not be obtained.

Furthermore, as mentioned above, vinyl chloride resin is used as the insulating material for the flat cable, and polycarbonate resin other than vinyl chloride resin is often used for the insulating material constituting the socket body, and both may be used together. There was a problem that a suitable adhesive could not be found.

Therefore, the present invention is an attempt to improve the above-mentioned conventional drawbacks, and the purpose of the invention is to provide a decorative lighting system in which a socket body is attached to a flat cable without using adhesive. It is an object of the present invention to provide a decorative lighting device that can be fixed.

(Means for Solving the Problems) In order to improve the above-mentioned drawbacks of the conventional technology, the present invention is to attach a light bulb to a flat cable in which a plurality of strip-shaped conductors arranged parallel to each other are coated with a flat synthetic resin. In a decorative lighting device, in which a plurality of socket bodies are attached, and a terminal of a light bulb attached to the socket body is electrically connected to the strip-shaped conductor, the bottom periphery of a bottomed cylindrical synthetic resin socket body is provided. A first welding flange body is provided which has a first welding plane that is thermally welded to the flat cable and is integral with the socket body, and the first welding flange body has the first welding plane. A second welded collar body made of the same material as the synthetic resin constituting the flat cable is fixed to the flat cable, and at least one of the first and second welded collar bodies is fixed to the flat cable. The object of the present invention is to provide a decorative lighting device which is thermally welded to a flat cable, a light bulb is attached to the socket body, and the terminal of the light bulb passing through the bottom of the socket body is connected to the strip conductor of the flat cable. .

(Function) In the decorative lighting device according to the present invention, a terminal piece for a wedge light bulb extending from the lower part of the socket body to the outside is inserted into the interior through the notch of the flat cable and brought into contact with the strip-shaped conductive wire, and then the terminal piece is inserted into the terminal piece. The socket body is placed on the flat cable so that the lower bottom of the socket body covers the part into which the piece is inserted, and then the first and second welded flange bodies are brought into close contact with the flat cable, and the Sonic welding. At this time, the second welded flange is of the same insulating material as the flat cable, so even if the socket body and the flat cable use different insulating materials, the flat cable and the second
The welded flange body adheres firmly.

(Embodiment) In FIG. 1, reference numeral 1 indicates a flat cable formed by covering two band-shaped conductive wires 2 with transparent vinyl chloride resin. Reference numeral 10 denotes a socket body according to the present invention fixed on the flat cable 1, which is formed into a cylindrical body with a bottom, and in the case of the embodiment, is integrally molded from the same vinyl chloride resin as the flat cable 1.
The socket body 10 has a socket hole 11 at its center into which the leg portion 3a of the wedge light bulb 3 is fitted, and a pair of connecting terminals 12 are arranged in the socket hole 11. The connection terminal 12 is the second
As shown in the figure and FIG. 3, the spring pieces 12a, which are bent in a dogleg shape and facing each other, elastically clamp the foot 3a of the wedge light bulb 3, and are firmly connected to the wire terminal 3b protruding from the foot 3a. It is configured to be connected to the terminal, and is integrally provided with a long strip-shaped terminal piece 13 at the lower end. As shown in FIGS. 4 to 6, the socket hole 11 has a rectangular shape, and a connecting hole 15 through which the terminal piece 13 protrudes is formed at the bottom of the socket hole 11.
is drilled there. The two terminal pieces 13 are bent parallel to each other along the longitudinal direction of the conductive wire 2 of the flat cable 1 at the bottom of the socket body 10, and a cut is made from the tip of the terminal piece 13 to the sheath of the conductive wire 2 of the flat cable 1. It is pushed into the notch 4 and comes into close contact with the conductive wire 2 for mechanical and electrical connection. 12b is the spring piece 12
This is the connecting piece of a.

A welded flange 14 is provided on the lower edge of the socket body 10 in the same direction as the flat cable 1, and a flat surface connected to the flat cable 1 is formed on the lower surface of the welded flange 14. This plane is brought into close contact with the flat cable 1, and the collar body 14 is integrally welded onto the sheath of the flat cable 1 by ultrasonic welding, thereby fixing the socket body 10 to the flat cable 1. In addition, 16 is a bottom groove provided at the bottom of the socket body 10, and 17 is a guide groove for the terminal piece 13 provided at the bottom of the flange body 14 in communication with the bottom groove 16.

On the other hand, the socket body 10 is connected to the flat cable 1
On the other hand, if the socket body 10 is integrally molded with polycarbonate resin or the like which is strong in terms of heat and strength, the collar body 14 of the socket body 10 cannot be directly welded to the flat cable 1. 4 and 6, a flat cable 1 covering this collar body 14 is shown.
A welded collar body 20 made of the same vinyl chloride resin as the coating is shown. This welded collar body 20 is temporarily bonded to the tip of the welded collar body 14 by suitable adhesive means, and has a flat surface connected to the flat cable 1 on its lower surface.

In this case, the flange 14 of the socket body 10 is covered and the welded flange 20 is attached, and the welded flange 20 is fixed by ultrasonic welding onto the covering of the flat cable 1, and the socket body 10 is fixed to the flat cable 1. Attached to cable 1.

As is clear from the above embodiment, first the long terminal piece 13 of the socket body 10 is connected to the flat cable 1.
Insert it into the inside through the notch 4 of the socket body 1 and contact it with the band-shaped conductive wire 2 of the flat cable 1.
0 on the flat cable 1. Then,
Welding plane on the bottom of the socket body 10, welding flange body 20
The welding plane is brought into close contact with the surface of the flat cable 1, and ultrasonic welding is performed to weld the contact surface with the flat cable 1. In this case, even if welding is impossible when the material of the socket body 10 is different from that of the flat cable 1, the welding collar body 20 is sufficiently welded to the flat cable 1 and the socket body 10
