Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric cord used for a tree, a Christmas tree or the like.

[0002]

[Prior Art]

 In the conventional cord for tree illumination, wires with light sources arranged at appropriate intervals are wound around the tree, and a plurality of such wires are collected under the tree and connected to a power source with a transformer interposed.

[0003]

[Problems to be solved by the device]

 When arranging multiple wires with light sources arranged, the tree lighting cord was installed outdoors, so it took time and effort to prevent the exposed parts from being drip-proof and waterproof.

[0004]

[Means for Solving the Problems]

 In view of the above-mentioned circumstances, the present invention connects two parallel conductors with an appropriate interval between the two parallel conductors in order to provide a cord for electric decoration which is excellent in workability while satisfying the requirements of drip-proof and waterproof. This is a cord for electrical decoration in which the light source is connected to the female connector of the base line cord, and the male connector of the electrical decoration line having a male connector at the base can be connected or disconnected.

[0005]

[Action]

 By fitting the male connector of the electric line to the female connector arranged at an appropriate interval of the base line cord, the light source of the electric line can be connected.

【Example】

 Hereinafter, the present invention will be described in detail with reference to specific embodiments shown in the accompanying drawings. FIG. 1 shows an overall outline of the electric code. A plurality of electric decoration wires 4 having a light source 3 are connected to a base cord 2 in which female connectors 1 are arranged at appropriate intervals, an extension cord 5 is connected to the base of the base cord 2, and the other end of the extension cord 5 is connected to the other end. A transformer 7 is connected through a transformer lead wire 6, and this transformer 7 is connected to an AC100V power source.

FIG. 2 is a circuit diagram of an example of an electric cord. Two conductors 11 are arranged in parallel, and a plurality of female connectors 1 are connected between the parallel conductors 11 at appropriate intervals. Eight light sources 3 connected in series between the two parallel conductors 21 are connected at appropriate intervals.

Details of the female connector 1 of the baseline cord 2 will be described below. 3 is a front view of the female connector 1, FIG. 4 is a plan view of FIG. 3, and FIG. 5 is a sectional view taken along line VV of FIG. The meso-connector 1 is provided with two insertion holes 32, 32 in an insulator 31, and metal cylinders 33, 33 are fitted therein, and the bottoms of the insertion holes 32, 32 are electrically connected to the conductor 11. Reference numeral 34 is a rubber ring. Further, the details of the male connector 41 of the electric decoration wire 4 are shown below. 6 is a front view of the male connector, FIG. 7 is a bottom view of FIG. 6, and FIG. 8 is a sectional view taken along line VIII-VIII of FIG. The insulating cylindrical body 42 is formed so as to receive the coupling projection 35 of the female connector 1, and conductor projections 43, 43 for fitting with the metal cylinders 33, 33 of the insertion holes 32, 32 are formed in the cylindrical body 42. The conductor projections 43, 43 are connected to the conductors 21, 21 by projecting them.

A female connector 1 A shown in FIGS. 9 and 10 is arranged at the tip of the base line cord 2. The female connector 1A is the same as the female connector 1 except that the conductor 11 extends to one side and does not extend to the other side. Next, the connection portion of the base end cord 2 with the extension cord 5 is as follows. 11 is a front view thereof, FIG. 12 is a plan view of FIG. 11, and FIG. 13 is a sectional view taken along line XIII-XIII of FIG.

A male connector 51 is fixed to the base end of the base line cord 2, and a meso connector 52 is fixed to the distal end of the extension cord 5. The male connector 51 has conductor projections 54, 54 projecting from the inside of the cylinder body 53 of the insulating cylinder body 53, and the conductor projections 54, 54 are connected to the conductor wire 11. On the other hand, the female connector 52 is formed with a connecting protrusion 55 so that it can be fitted into the insulating cylindrical body 53 of the male connector 51, and has insertion holes 56, 56 for receiving the conductor protrusions 54, 54. The metal cylinders 57, 57 are fitted in the insertion holes 56, 56. Reference numeral 58 is a rubber ring.

When using this electric cord for lighting a tree, for example, first hook the base cord 2 on the root portion of the tree or the like, and then wire the electric cord 4 to the necessary portion of the electric cord. The male connector 41 provided at the base end of the electric decoration line 4 is fitted into the female connector 1 of the base line cord 2 for connection. That is, the insulating cylindrical body 42 of the male connector 41 is externally fitted to the connecting projection 35 of the insulating body 31 of the female connector 1, and the conductor projections 43, 43 are fitted and connected to the metal cylinders 33, 33.

The other electric decoration wire 4 is hung around a required branch, and the male connector 41 at the base end thereof is similarly connected to the female connector 1 at the corresponding position. A rubber cap (not shown) is fitted to the female connector 1 of the illuminated wire 4 where the male connector 41 is not connected to ensure waterproofness. Similarly, the male connector 51 at the base end of the base line cord 2 is similarly fitted and connected to the female connector 52 of the extension connector 5, and the transformer lead wire 6 is connected to the base end side of the extension connector 5 to connect the transformer 7. Then, the transformer 7 is connected to the AC100V power source.

[Effect of the device]

 As described above, the present invention is a light emitting device having a light source connected to a female connector of a base line cord having two parallel conductors and having female connectors connected between the parallel conductors at appropriate intervals and having an male connector at the base. Since this is a cord for electrical decoration that can connect or disconnect the male connector, it is possible to install the electrical decoration wire at the place where the electrical decoration is required and to connect it by inserting the male connector into the female connector. Yes, it is easy to remove when not needed. Therefore, in the present invention, it is possible to easily attach the electric decoration wire of the electric decoration cord and to provide a reliable waterproof / drip-proof structure.
