Description

Construction communication terminal box waterproof structure{TERMINAL CASE HAVING A WATERPROOF STRUCTURE}

The present invention relates to a waterproof structure for a communication terminal box for a building, and specifically, it is possible to prevent contamination of a terminal or a communication line installed inside the terminal box by preventing water from seeping into a joint portion of a terminal box and a cover installed on a wall of a building. It relates to the waterproof structure of the communication terminal box for construction.

The terminal box refers to a box installed on the wall of a building so that terminals for connecting various electric wires, telephone lines, communication lines, etc. to be introduced into the building can be installed inside.

The terminal box as described above is pre-installed so as to be buried in the wall of the building in the process of constructing the building, or is installed on the wall of the building in which the construction has been made, using a separate fixing mechanism.

For example, a conventional terminal box is installed to be buried or protruded in a wall of a building, as in Document (1). In other words, this is to supply the communication cable intended to be led into the inside of the building to each home that lives in the building by connecting it with the terminal of the terminal box, and using a terminal (Wintek block) installed inside the terminal box, etc. It is configured so that the wiring is made.

However, conventional terminal boxes such as document (1) are configured to install various terminals connected to the communication line inside the box-shaped box, and the front of the terminal box is configured to be used in combination with a cover to facilitate opening. It is common.

Accordingly, in conventional terminal boxes, when it rains at the position where the terminal box is installed, or when water is sprayed to the position where the terminal box is installed, water penetrates into the connection part between the terminal box and the cover, which can damage the terminals and communication lines installed inside the terminal box. There was a problem.

In addition, due to the above problems, there was a problem that the terminal installed inside the terminal box and the communication line were damaged, which could cause damage to homes or businesses using the communication line, and accordingly, there was a problem that the maintenance and repair cost of the terminal box could increase. .
