Description

Plug and receptacle for distributing the electric wires in the structure}

The present invention relates to plugs and receptacles for building wiring, and more particularly, to plugs and receptacles that enable ceiling wiring in buildings where conduits are not constructed.

All power supplies of conventionally known buildings are connected between conduits and outlet boxes (hereinafter referred to as boxes) embedded in concrete ceilings of each floor, and metal pipes or rigid PVC pipes (hereinafter referred to as conduits) embedded in the ceiling of semen concrete. Collectively).

The box and the conduit are placed before the concrete placement of the building (after rebar placement), and the construction is completed with the box open toward the bottom after the concrete placement.

Therefore, it is possible to supply power to lighting fixtures in the ceiling by inserting them into the conduit which is buried when additional work such as ceiling boards, various lighting fixtures, disaster prevention and fire alarm air conditioning facilities are carried out. .

After completing the work that requires the various power supply of the ceiling plate, the power line connection work is once again performed between the ceiling and the ceiling plate in order to provide lighting facilities suitable for the office atmosphere of each floor. That is, the power line is drawn from the box embedded in the concrete on the constructed ceiling plate, and drawn out around the ceiling plate to connect and connect the power line to the lighting fixtures installed on the ceiling plate.

The construction of the electric wire for power supply between the ceiling and the ceiling plate has a disadvantage in that the power supply line on the ceiling plate is rebuilt every time since the layout structure must be changed at any time according to the position of each floor office. As a result, the arrangement of power lines on the ceiling board is complicated, and sometimes the exposed wire strands may cause fire accidents as well as human accidents due to electric shock or short-circuit during long-term use.

In addition, the relocation of the electric wires on such a ceiling plate also has the problem of double wiring with the electric wires in the conduit embedded in the ceiling. In other words, even though the power line is already laid in the conduit, when the concrete is laid, the power supply line such as the lighting facility changed according to the layout of the office is redesigned, so the power inside the conduit buried in the ceiling to use each office space The power line on the line and the ceiling plate make up the power supply line. Such a dual power supply line has a high risk of leakage current, increases the risk of electric leakage, and may cause inductive interference of office communication facilities.

On the other hand, in the connection structure between luminaires, a general plug or an outlet for simply connecting the power line as it is or accommodating a plurality of connection terminals is used. For simple connection of the power line, the extension of the power line drawn from the box may be connected or fixed to the terminal formed in each lighting fixture, socket, outlet, etc., but a flexible metal tube may be used for a more neat connection of the power line.

However, in case of the former, there is a risk of short circuit or short circuit due to peeling off the covering of the power line.In the case of using a flexible metal tube, a plug and a receptacle of a plurality of terminal holes integrally equipped with pin terminals at each end of a plurality of power lines (the present invention described later) In case of using directly the union member and the female member), there is a problem in that the terminals are separated from the plug and the receptacle when the metal tube is pulled, and the strength of the plug and the receptacle is weakened, so that there is a defect that is easily broken or unstable.

The present invention is to provide a power supply that can omit the arrangement of the conduit during the construction of the ceiling concrete of the building. This power supply facility is simpler than the conventional concrete construction and reduces the unit cost according to the conduit construction of the building.Therefore, the power supply structure is arranged only on the ceiling plate. It also reduces the cost of power supply facilities by relocating properly to the interior design even if the connection line is different without the whole re-installation.

In particular, the present invention overcomes the shortcomings of the redundant equipment as described above, and the copper wire exposure of the power line is less, thereby preventing a short circuit accident caused by the copper wire exposure on the conventional ceiling plate, and the power wire can be installed with a flexible metal tube. In order to provide a safe connection device to prevent the departure of the power line in the light, it is to provide a plug and receptacle with improved assembly in the manufacturing process of such a connection structure.

The present invention improves the power supply facilities for laying a separate conduit in a concrete ceiling and does not bury the conduit in the ceiling, but instead provides a power connection structure that enables power supply in the space between the building ceiling and the ceiling plate. The plug and receptacle is ultimately settled for connection with flexible metal pipes, and is easily assembled to accommodate the required lengths and wiring of plugs and receptacles with metal pipes in large-scale manufacturing as well as on-site construction. And its purpose is to provide receptacles.

The present invention eliminates the functions of plugs and receptacles in the past, and is suitable for connection with flexible metal pipes, as well as a one-piece receptacle to which one plug is connected, as well as a plurality of two- or more receptacles. The goal is to provide an improved plug and receptacle to implement.
