Description

Diversity device for ceiling wiring

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling wiring branching device, and more particularly, to a ceiling wiring branching device comprising an assembly type plug which is advantageous for ceiling wiring and the like, and a plurality of branching means which can be connected at the same time.

In general, in-ceiling wiring is essentially required for lighting fixtures of building ceilings. Known intra-ceiling wiring has been done by installing and connecting flexible tubes with wires wired from branch boxes connected to conduits installed on the ceiling to lighting fixtures installed on double ceiling plates.

This wiring method has low variable capacity after initial installation, which causes a lot of loss of materials and manpower due to relocation or remodeling, and increases wiring cost and loss of voltage due to long wiring distance. In addition, when the repair is required or when installing a new power supply line, it is cumbersome to check the circuits and wires individually, and sometimes there is a problem in the wire arrangement, such that there is a risk of overheating of the wires due to an increased load on a specific terminal.

The problem with the wiring installation structure in the ceiling is that the contact area is increased due to the installation of various facilities such as the ventilation system and the heating device in the ceiling. It was.

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 in which ceilings can be arranged in accordance with various layout designs by incorporating a plurality of cables in a flexible tube and selectively connecting plugs or receptacles to the conduit side of both ends of the embedded multiple cables. That is, extension of electric wires is made possible by 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 was possible only to arrange one conduit in a straight line or to connect a wire in a right direction, but it had a structural limitation in branching a plug into a branch in one branching means.

In addition, such a wire branch structure has the advantage of using a conduit in which a plurality of wires and cables are assembled, but only supports the outside and locks the connection state when the female and male members are connected at the same time. There was only room for improvement in terms of improvement in assembly performance, which is advantageous for manufacturing and convenient for construction, by implementing a new cover housing that is merely a function of canceling.

For example, it is possible to branch connection of conduits through straight and downward or three-way T-shaped receptacles through a receptacle with one female member, but branching means capable of connecting horizontally as well as downward in four directions. Could not be implemented. This is because the branch connection in multiple directions using one branching means is required because it increases the number of equipment parts and economics due to the manufacture of receptacles suitable for straight connection, T-type connection and cross-type connection.

Therefore, as one branch connecting means, there is a need for branching means that can be connected in a straight line, three directions, and four directions as well as in five directions.

In particular, the first improved plug and receptacle has a complicated locking structure, it is not easy to connect and disconnect according to the locking and release of the plug during manufacture as well as in the field construction, there was a disadvantage in manufacturing as well as construction.

The present invention provides a plug and a receptacle constituting a body by correspondingly and assembling up and down with two opposing disks having at least one alternating opening and a blocking wall formed along an edge on a hollow disk, thereby providing a simpler direction. It is an object of the present invention to provide a ceiling wiring branch device capable of wiring design.

Another object of the present invention is to provide a ceiling wiring branch device further comprising a seating structure so that the plugs connected to the receptacle are applicable to the multi-wire male and female connecting members.

The present invention provides a locking and releasing structure in which the connection and disconnection of the plug and the body are made easier by improving the disadvantages of the conventional ceiling wiring branch devices, and reducing the number of assembly parts for the manufacture of the branching means. It is also an object of the present invention to simplify the manufacture of the device, and to provide a ceiling wiring divergence device capable of providing various application wirings according to the branching function without mobilizing several branching means in construction.
