Along the trunk of the tree, multiple lighting lines are arranged along the branches.

In the above-mentioned electric decoration, when connecting the main cable and the electric decoration line, a part of the main electric cable and the coating of the terminal portion of the electric decoration wire are connected to expose the conductor, and the conductor is connected to each other. If the method is adopted, there is a problem that connection is very troublesome.

In order to solve the above-mentioned problems, the actual Kaihei 5-
In Japanese Patent No. 83934, a female connector is attached to the tip of an extension cord connected to a power source via a transformer, and a male connector attached to the proximal end of a baseline cord is connected to the female connector, and a plurality of cords are attached to the baseline cord. Described is a cord for electrical decoration in which female connectors are attached at required intervals and a male connector attached to the base end of the electrical decoration wire is connected to each female connector.

Since the above-mentioned electrical cord is a connection using a female connector and a male connector, it has a feature that it is very easy to connect the cords and to connect the base cord and the decorative line.

[0007]

By the way, in the cord for electric decoration disclosed in the above publication, a plurality of female connectors for connecting the electric decoration line are attached to the base line cord at required intervals. However, it is necessary to position the extremely long base line cord along the trunk of the tree and near the base of the branch around which the electric decoration line is wound, and it is necessary to position the female connector of the base line cord, which is very inconvenient for wiring.

Further, when a plurality of branches are close to each other, there is a disadvantage that the base line cord along the trunk between the branches is slackened and the appearance is deteriorated.

An object of the present invention is to provide an electric wire for electrical decoration, which is easy to perform a wiring work and can be formed in a good appearance.
