Description

Cover Plate For Connecting Electric Wire

The present invention relates to electrical piping materials, and more particularly, to a cover plate for connecting wires for easily and safely connecting electrical wires installed in a building to a switch box or a distribution box.

Conduit is widely used to install electric lights or outlets in various buildings. The conduit is in the form of a corrugated tube made of a flexible material, and it is common to have impact resistance. The conduit may be embedded in a wall or column, or installed in an exposed state. At the end of the conduit, an electric device such as a switch box, a distribution box or an outlet box is installed.

Therefore, the connection part of these electric devices and the conduit exists. Conventionally, they were connected using a cable tie or connected using an iron band that can be tightened with screws. Also, a connector such as the Republic of Korea Utility Model Registration Application No. 20-2005-0001547 has been proposed.

This prior art has a structure in which the protective gear and the packing coupled to the upper and lower sides of the connector stably support the outer and inner surfaces of the corrugated pipe in a watertight state, respectively. This technology not only improves the watertightness between the conduit and the connector connection part, but also prevents the conduit's inner diameter from being reduced or the conduit from being bent due to external impact, thereby providing the effect of stably maintaining the bonding state of the conduit.

In addition, Republic of Korea Patent Application No. 10-2017-0058961 discloses a connector for connecting a conduit for connecting a plurality of conduit tubes to a junction box embedded in a wall, inserted through a fastening hole formed in the junction box, a flange is formed at the upper end, and a concave-convex corrugated pipe and an elastic fastening part elastically coupled to the corrugated tube body of the fixture on one side around the outer ring frame, the other side is provided with a threaded part, and a threaded part is formed on one side to be fastened with the threaded part of the coupling, The other side provides a configuration in which an elastic fastening portion for elastically coupling the conduit made of a corrugated tube body is formed.

The conventional cover plate for wire connection is a configuration for fixing a conduit by screwing it in the installation process, and it is difficult to see it as a simple configuration because it consists of two or three parts. Since it has to be screwed in, an auxiliary tool such as a spanner is required, and it is difficult to use a spanner in a narrow space, making installation difficult.

Meanwhile, during wall construction, the distribution box is fixed to the formwork and then concrete is poured so that the distribution box is embedded in the wall. In order to cover the opening of the distribution box, the cover 100 shown in FIG. 7 is used. The cover 100 is provided with a screw fastening hole 101 for fastening a screw, and a wire through hole 103 for passing an electric wire or conduit. In the case of installing an electric wire through the electric wire through hole 103, there is a problem that the electric wire flows, which is inconvenient and dangerous.

In this regard, Korean Utility Model Registration No. 20-0396255 has been proposed. However, according to the present technology, there is a problem that the conduit is easily pulled out when it is pulled out in a fixed state, and there is a problem of wobbling when the cover plate is installed in an uneven place. In other words, there is a problem of poor stability during installation, so there is room for improvement.
