Description

  The present invention relates to a three-way connector, and more particularly, to a three-way connector for a light string that can extend a light string to a required length.

  A light string includes a plurality of small light bulbs that are electrically connected to each other by wires. The user can hang or hang a light string on a tree or roof depending on the length of the light string to enhance the festive atmosphere, especially the festive atmosphere during the Christmas season. However, since the light string requires an independent power supply, a user must prepare a plurality of power sockets in order to make the light string cover a large area. Alternatively, the user must prepare a plurality of extension wires each having a power socket for the power supply. When a plurality of power sockets are used, storage of the plurality of power sockets poses a major problem for a user because space is required for the power socket and electric wires are easily entangled. Even with alternative means and methods, users must face the problem of tangling extension wires. In addition to this, the cost of preparing the decoration is increased by accessories such as extension wires.

  It is an object of the present invention to provide an improved connector to overcome or mitigate the above problems and disadvantages.

  SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved three-way connector so that a light string can be continuously connected to another light string.

  Another object of the present invention is to allow the three-way connector to be easily electrically connected to each other so that the three-way connector can be easily extended to any length as required, thereby enabling the user to connect the three-way connector. An object of the present invention is to provide a three-way connector that can be extended to a required length.

  The three-way connector according to the present invention is provided to couple two power cords, each of which receives two electric wires, and each wire from one power cord and each wire from the other power cord. Two connecting plates, two tubular extensions respectively connected to the two connecting plates, and extending downward with respect to the electric wire of each power cord, and a casing surrounding the power cord and the connecting plate. A casing having an extension having two slots formed to receive the two tubular extensions, respectively, wherein two legs of a light string plug are provided with the electric wire to obtain power. And each can extend into the two slots so as to be connected.

  Preferably, a boss is formed on the outer periphery of the casing, and the boss is provided with a through-hole, and can be hung or hung on an appropriate surface via the through-hole.

  Preferably, there is provided a nail portion having two shelf portions formed on the outer periphery and having two shelf portions separated from each other to receive the casing between the two shelf portions, whereby the nail portion has It can be firmly fixed to the surface.

  Other features and advantages of the present invention will become more apparent from the following description with reference to the accompanying drawings.

  Referring to FIGS. 1 and 2, a three-way connector according to the present invention includes a power cord 10 (having two power cords in a preferred embodiment) and two power leads that allow the power cord 10 to extend. It includes a casing 20 having an open end 21 and two slots 22 formed in an extension 23 formed with the casing 20 for connection to two electric wires 11 received in the power cord 10. An external thread 231 is formed on the outer periphery of the extension 23. A boss 24 is formed on the outer surface of the casing 20 so as to be opposite to the extension. The boss 24 has a through hole 241 formed therethrough.

  Two power cords 10a, 10b are provided extending into the casing 20 from different open ends. The power cords 10a and 10b are connected to each other by soldering or otherwise connecting the connection plate 12 to connect the two wires 11 of the power cord 10a to the two wires 11 of the power cord 10b, respectively. . A tubular extension 13 made of conductive material is formed in the connecting plate 12 so as to extend downward into one of the corresponding slots 22 of the extension 23.

  In FIG. 3, the three-way connector according to the present invention includes a plug 30 having two legs 31 respectively corresponding to the two tubular extensions 13 and a cap 32 having an inner thread 321 formed on the inner surface. An example applied to a provided light string is shown.

  After the two legs 31 have been inserted into the corresponding tubular extensions 13, the two legs 31 are electrically connected to the two electric wires 11 of the power cords 10 a, 10 b via the connection plate 12. You. Therefore, the plurality of light strings are connected to each other by the three-way connector according to the present invention. In addition, the through holes 241 allow a user to use fasteners (not shown) to hang the three-way connector of the present invention along a suitable shape, for example, along a roof. As a result, when a plurality of three-way connectors according to the present invention are connected in series, only one power source is required for connecting the plurality of light strings.

  Referring to FIGS. 5 and 6, in another embodiment of the present invention, the casing 20 includes a nail portion 26, and the nail portion 26 is separated from each other by two shelf portions formed in the nail portion 26. 261.

  The space formed between the two shelf portions 261 is such that when the casing 20 is received by the user in the space between the two shelf portions, the three-way connector according to the present invention is firmly fixed to the surface. The casing 20 is formed so as to be accommodated in the space. Thereby, the neon lamp 40, that is, the light string can be connected to the extension portion 23 in order to electrically connect the light string.

  While the various features and advantages of the invention have been described above in connection with structural and functional details, it will be understood by those skilled in the art that changes in detail, particularly with regard to the shape, size and arrangement of parts, are possible. It is clear to
