Description

Connection box for wiring box

The present invention relates to a connection box for a wiring box, the connection box that extends the front of the wiring box in the inner side of the side wall or the column to the same as the surface of the side wall is separated and combined in multiple stages to facilitate the connection work. The present invention relates to a connection box for a wiring box that can be used according to the installation conditions.

In general, the connection box for the wiring box is installed at the front of the wiring box which secures a space for the attachment of equipment such as a switch or an outlet to the side wall or the pillar and the wiring according to it, and is located in front of the wiring box installed inside the side wall and the pillar. When the distance between the side wall and the surface according to the formation of the column is not matched, the front side of the wiring box is extended to allow the wiring of the wire and the installation of a switch or an outlet.

That is, the wiring box is installed so that the front coincides with the inside of the side wall at the same time as the concrete is poured, and the side wall is completed by attaching the heat insulating material and the interior material to the inner side of the side wall, Steps occurred on the surface of the interior material, and in order to prevent this, the front of the wiring box built in the concrete was extended, and the switch or the outlet was fixed to the inside thereof.

At this time, the connection box extending the front of the wiring box to be the same as the surface of the interior is composed of a single body having a predetermined standard was used to connect to the front of the wiring box.

However, when the connection box is connected to the wiring box installed inside the concrete, it must be used selectively according to the thickness of the heat insulating material and the interior material, and the connection box is protruded to the surface of the interior material because the unified size of the connection box is not varied. According to the thickness of the heat insulating material and the interior material generated and attached to the inside of the side wall, a problem that is not easy to use has been raised.

In addition, according to the type of outlet installed in the connection box, there is an unreasonable problem of having to provide a variety of specifications of the connection box connected to the front of the wiring box, according to the rise in manufacturing cost and workability according to the installation of the outlet and switch This deteriorating problem has emerged.

Therefore, the present invention is to solve the above problems, it is easy to connect with the wiring box installed on the inside of the concrete, and the connection structure of the connection box according to the thickness and the thickness of the insulation and the interior of the insulation for connection and is connected The present invention provides a connection box for a wiring box that facilitates the connection and application of the connection box according to the working conditions, and that the combination of the switch or the outlet of each type coupled to the connection box is made in common, thereby improving workability and convenience. There is a purpose.
