The present invention relates to a branching device consisting of a receptacle which can be connected simultaneously in the 5-axis direction, so that the plug is advantageous in ceiling wiring, etc. More specifically, the upper case and the lower case is divided into a case, the connection opening is formed in five directions; And a receptacle seated inside the case and configured by combining five engaging members corresponding to the respective connecting openings of the case, wherein the receptacles are bundled into the respective engaging members. The connecting end of the 5-axis connecting pin of the present invention relates to a ceiling wiring branch device.

In general, the wiring in the ceiling is essential to the lighting fixtures of the building ceiling.

In the meantime, the wiring inside the ceiling is provided with pipes through which electric wires pass through, such as by embedding or exposing the concrete slab from the power breaker to the location of each luminaire, and branching the electric wire at each luminaire. Wires from the junction box to the junction box, and wires from the junction box to each luminaire inside the separate flexible tube, combine one end with the junction box, connect the power cable inside, and fix the other end to the lower ceiling structure. Wiring work is done by connecting the flexible tube to the luminaire and connecting the power line with the wiring inside the luminaire.

This wiring method is not easy to add or change in the process of use, and since the initial construction and after-care are complicated, the wire strands and cables are tangled intricately. There are also a lot of problems in the arrangement of wires, such as the hassle and sometimes intensively increased the load on a specific terminal, there is a risk of overheating of the wire.

The problem of such a ceiling installation structure in the ceiling is that due to the installation of various facilities such as various ventilation pipes, electrical appliances in the ceiling, the contact area is increased, and the fire is also frequent due to a short circuit due to an electrical short circuit in an old wire used for a long time.

Recently, various arrangement means have been devised to arrange safety in the ceiling by arranging the wiring structure in the ceiling corresponding to the luminaire of the ceiling.

Among them, there has been proposed a conduit arrangement structure that can be arranged in a ceiling corresponding to various layout designs by inserting a plurality of cables into a flexible tube and selectively combining plugs or receptacles with the conduit side of both ends of the embedded multiple cables. That is, extension of electric wires and the like can be made using an application connection structure such as a conduit having a plug and a plug, a conduit having a plug and a receptacle, and a conduit having a receptacle and a receptacle.

However, such a wiring connection structure is possible to connect only one conduit in a straight line so that the wire connection in the right direction is possible, but there is a structural limit to branching the plug into several branches in one branching means.

For example, it was possible to connect the conduit through a receptacle with one female member in a linear direction or a three-way receptacle with three female members, but it was very difficult to realize a four-way branch structure.

However, a branching device having a branching structure in four directions has been registered in Korean Patent Laid-Open Publication No. 2003-62025.

This four-way branching device has a structure in which four female coupling members are connected to the inside of the receptacle, and then a plurality of wires are drawn to the lower portion thereof and connected to each female coupling member.

However, the branching device of such a structure is very difficult to manufacture unless the expert because it has to wire a plurality of wires to the lower portion of the receptacle to connect to the mating member.

In addition, the number of parts increases accordingly, and the size is also increased because the wires of several strands are bundled together in a limited space and connected to the female coupling member, and the risk of short circuit due to an electric leakage caused by an increase in the contact portion of each wire is always included. Has been.

In addition, the branching device of the four-way has a drawback that must be installed in consideration of the lead wire when installing the wiring in the ceiling because the lead wire is fixed. Therefore, there is a problem that the installation structure is different depending on the shape of the building ceiling.

Therefore, there is a need for a branching device capable of branching in five directions in which another female member is connected so that a separate plug can be connected to the wire leading line so as to be compatible with the incoming line in question in the four-way branching device.

In addition, it is easy to assemble by reducing the number of parts, it is easy to mass production, the production cost can be lowered, and a branching device that eliminates the risk of fire is required.

The present invention has been made in view of the above problems, and for this purpose, the first object of the present invention is a ceiling wiring including a receptacle connectable to a direction for selecting an input plug and an output plug in a 5-axis direction to favor a ceiling wiring or the like.
