The present invention relates to an electrical terminal box of a building with improved workability, and more specifically, to the inside of the buried box buried in the wall to install the inner case that can be rotated and moved back and forth at a predetermined angle and to install the connection terminal in the inner case It relates to an electrical terminal box of the building to improve the workability so that the worker can work conveniently.

In general, the communication terminal box is used as a means of connecting subscriber's communication means to the communication network by connecting the CO line connected to the outside of the building and the internal side wired for the subscriber inside the building. Most of them change only slightly, and the main purpose of the connection of communication line is to connect the end of CO line and the end of internal line to each other so that electric signal can be transmitted and received along communication line.

Therefore, direct connection between CO lines and stations is also possible, but it is necessary to change the connection between CO lines and stations for reasons such as change of subscriber's communication facilities, decrease and increase of communication line capacity, or change of subscriber itself. It is common to install a terminal box that collects the connection terminals to easily change the connection state between the station and the station.

 However, the conventional terminal box is embedded in the case of a rod called metal wire, which is a simple electrical conductor in the case commonly referred to as a railroad, so that the trunk lines and internal lines can be connected to each other, and usually recessed in a wall of a certain location of the building. Most of them had large capacities to form wealth and to be buried there.

Thus, once installed, most of them were almost impossible to change or move, and these were rather inconvenient and expensive to connect small capacity lines.

Moreover, most of the conventional terminal boxes expose the connection parts of the connection terminals, i.e., the wiring parts are electrically connected by soldering, lapping or wiring by wiring or soldering the wires. As a result, there are risks of instability and short circuit in communication due to various causes such as damage and rust.

And the communication terminal box should always be opened and operated by the operator to add new communication lines or check the communication quality, but the conventional communication terminal box is installed on the lower part of the wall so that the worker should work with uncomfortable posture during the line work. There is. In addition, since it is installed under the wall, it is inconvenient to work because the eyes are not free even in the sitting position of the worker.

1 shows a conventional communication terminal box 1, in which a connection terminal 5 is connected to a communication cable 6 in a buried box 3 embedded in a wall 2, and the cable 6 is a buried pipe. (7) enters the buried box (3) and is connected to the connection terminal (5). The door 4 is fixed to the front opening of the buried box 3 so that the operator can open and close the door 4 and work on the connection terminal 5, and the buried box 3 below the wall as described above. ) Was uncomfortable because it was buried.

The present invention has been made in order to solve the problems as described above, in addition to the buried box buried in the wall to install the inner case that can be rotated and moved back and forth at a certain angle therein and install the connection terminal in the inner case Provides an electric terminal box of a building that improves workability, which makes it easy to work and rotates and fixes it so that an operator can easily gaze in a sitting position even if a terminal box is installed at the bottom of the wall. There is a purpose.

In order to achieve the above object, the present invention has a protrusion formed at an upper portion of the rear wall surface of the box body which is opened at the front and embedded in the wall, and a hook rod is horizontally fixed inside the box body adjacent to the lower part of the step formed by the protrusion. The line inlet hole connected to the end of the buried pipe buried in the wall is formed on the upper surface of the box, and the B-shaped support plate is fixed to both side walls horizontally in the lower part of the inner box, and fixing brackets are formed on both sides of the opening. Buried box; A guide hole is formed on both side walls of the buried box so as to face each other, the guide hole is formed with a horizontal portion and an inclined portion integrally, and a guide portion is formed by cutting a portion of the upper wall surface of the horizontal portion; Projections are formed on both side walls of the box body with the front open, and are inserted into the guide hole through the protrusion insertion part, and two hook holes are formed at the upper end of the box body rear wall to be hooked to the hook rod. A line entry hole is formed, a flange is formed around the box opening, and is detachably fixed to the fixing bracket through a fixing hole formed at one side, and a handle is formed at one side of the box front end, and a connection terminal is formed inside the box body. Provides an electrical terminal box of the building, characterized in that consisting of;

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, the buried box 10 is embedded in the wall 2, the inner case 30 is fixed to the inside of the buried box 10, but the projection 33 formed in the inner case 30 buried box 10 It is a main configuration that the inner case 30 is rotatable by being inserted into the guide 20 formed in the guide 20.

The buried box 10 has an opening and closing door 16 formed at one front end of the rectangular box body 11 whose front is open, and the box body 11 is embedded in the wall 2.

A protrusion 17 is formed on the upper rear wall surface of the box body 11 toward the rear, and the hook rod 13 is formed inside the box body 11 adjacent to the lower portion of the step 18 formed by the protrusion 17. It is fixed horizontally. The protrusion 17 is configured to widen the space so that the hook hole 39 formed in the inner case 30 does not interfere with the box body 11 rear wall when the inner case 30 to be described later rotates.

A track inlet hole 12 connected to an end portion of the embedding pipe 7 embedded in the wall 2 is formed in the upper surface of the box body 11, and a b-shaped support plate 14 is formed in the lower portion of the inside of the box body 11. It is fixed to both side walls horizontally.

 Fixing brackets 15 are formed up and down on both sides of the opening 11 of the box body 11 to fix the inner case 30 to be described later. The fixing bracket 15 is formed of a B-shaped protrusion having a bolt hole.

Guides 20 are formed on both inner walls of the box 11 of the buried box 10, and the guides 20 are formed of guide holes 21 in which opposite portions fixed to the walls are opened. 21 is formed to face each other on both side walls of the buried box (10).

The guide hole 21 has a horizontal portion 22 and an inclined portion 23 integrally formed, a portion of the upper wall surface of the horizontal portion 22 is cut off to form a protrusion insertion portion 24, and a protrusion insertion portion 24. The protrusions 33 of the inner case 30 are inserted and fixed through the inner case 30.

The inner case 30 has protrusions 33 formed on both side walls of the box body 31 whose front is open, and is inserted into the guide hole 21 through the protrusion insertion part 24, and the rear wall of the box body 31. Two hooks 39 are formed at the top to be hooked to the hook rod 13. Hanging device 39 is a groove is formed in the lower portion of the protruding body and the groove is configured to be hooked to the hook rod (13).

The cable inlet 12 is formed on the upper surface of the box body 31 so that the cable 6 introduced through the line inlet hole 12 of the buried box 10 enters the box body 31 and the connection terminal 37. Is connected to.
