Description

[0001] EARTH DEVICE OF CABINET PANEL [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grounding apparatus for a distribution board, and more particularly, to a grounding apparatus for a distribution board that facilitates installation of a grounding wire in a distribution board, thereby improving convenience in construction.

In general, as disclosed in Korean Patent Application No. 2011-26534, a distribution board divides power supplied into a building to supply a load such as a lamp socket, monitors a voltage state supplied to the load, It is a device that assembles breakers and switches that block them when they occur. And serves as an inlet of the electric wire and prevents exposure of a line connected to the circuit breaker and the switch to prevent an electric accident in advance.

1 and 2 are perspective views showing a conventional ground bus bar for a distribution board.

As shown in FIGS. 1 and 2, the conventional distribution panel 10 serves to supply a commercial power source supplied into a building through a transmission line to each household, and the distribution board 10 is generally embedded in the inner wall of a household And the cover of the distribution board 10 is exposed to the outside to form one internal component of each generation.

In addition, the electric branching work of the distribution board 10 is carried out after each electric wire is taken out and cut into each furniture or each layer when an apartment or a general building is built. That is, electric wires are branched sequentially from the lowest layer to the upper layer, and a distribution pipe pipe is buried in ceilings or floors on each floor of each floor, and the electric wires are cut out through the pipe, , And the electric wire drawn out through the pipe pipe is connected to the distribution panel.

On one side of the distribution board 10, there is provided a ground bar 20 for collecting and grounding the various electric wires.

Here, the ground serves to protect the human body and the apparatus from electric shock, and to provide a reference voltage for stable operation of the electric equipment.

Specifically, the grounding bus bar 20 is formed with a plurality of grounding wire holes into which a plurality of grounding wires, which are various types of electric wires such as electric wires drawn from a communication device or electric wires drawn from a power device, are inserted, So that the electric wire from the lightning rod is connected to the ground bus bar 20 so as to be grounded.

The ground bus bar 20 is made of a conductive material and has a substantially rectangular structure and is formed with a fixing hole for fixing it to a wall surface or the like. In addition, the ground bus bar 20 is formed with a plurality of grounding line holes 21 for connecting various grounding lines. That is, the grounding line may be drawn into the grounding line hole and pressed by bolts, rivets, or the like.

However, since a plurality of grounding wire holes 21 formed in the conventional grounding bus bar 20 need to be formed with tabs or threads, the machining cost is increased. As a result, There is a problem in that the manufacturing cost is increased because the ground bus bar 20 is provided only with a bar made of the same material and is grounded, have. In addition, if damage such as breakage occurs in any one side of the ground bus bar 20, there is a problem that it is troublesome to remove the ground bus bar 20 and replace it with another ground bus bar 20 and reinstall it.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a grounding device for a distribution board that facilitates installation of a grounding wire in a distribution board to improve convenience in construction.

The grounding device for a distribution board according to the first embodiment of the present invention has a fastening portion 51a to be fastened to the wall on both sides and a grounding bolt 60 is provided on a portion of the fastening portion 51a projected and bent upward A ground bus bar 51 formed with a plurality of insertion holes 51b to be inserted therein; And a plurality of housings 52, which are positioned below the protruding bent portions of the ground bus bar 51 and in which the nuts 70 are housed.

The housing 52 is formed in a rectangular box shape and has a fitting projection 52a formed on one side thereof; An insertion groove 52b into which the fitting projection 52a of the housing 52 to be coupled adjacently is inserted is formed on the other side; And a hole 52c is formed in the upper surface thereof to receive the grounding bolt 60 in accordance with the insertion hole 51b of the grounding bus bar 51; A hexagonal column-like hole 52d through which the nut 70 is received passes through a lower portion of the plurality of holes 52c; And a protruding bar 52e inserted into the ground bus bar 51 is formed in the middle of the hole 52c.

According to the grounding apparatus for a distribution board of the present invention, it is possible to simplify the manufacturing process of the grounding bus bar, that is, to simplify the manufacturing process, thereby reducing the manufacturing cost and providing a housing to be assembled to the lower end of the grounding bus bar, Have.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

[Example]

4 is a perspective view showing a housing of a grounding device for a distribution board according to the present invention, and FIG. 5 is a view showing a housing of a grounding device for a distribution board according to the present invention FIG.

3 to 5, the grounding device for a distribution board according to the present invention has a fastening portion 51a for fastening to the wall on both sides thereof, and a portion of the fastening portion 51a, A ground bus bar 51 formed with a plurality of insertion holes 51b into which the bolts 60 are inserted and a plurality of nuts 70 housed below the ground bus bars 51, As shown in Fig.

The housing 52 is formed in a rectangular box shape and has a fitting protrusion 52a on one side and an insertion groove 52b into which the fitting protrusion 52a of the housing 52 which is adjacent to the other side is inserted, And a hole 52c is formed in the upper surface thereof to receive the grounding bolt 60 so as to coincide with the insertion hole 51b of the grounding bus bar 51. In the lower portion of the plurality of holes 52c, A hexagonal column-shaped hole 52d through which the grounding bar 70 is received is inserted through the hole 52c and a protrusion rod 52e inserted into the grounding busbar 51 is formed in the middle of the hole 52c.

One housing 52 having two holes 52c can be used when the grounding bus bar 51 has two insertion holes 51b and holes 52c can be used when there are six insertion holes 51b. Two housings 52 may be used in connection with each other or two housings 52 having three holes 52c may be connected and used.

In this way, the insertion hole 51b of the grounding bus bar 51 does not need to be subjected to a screwing process. Since the screwing is not performed, a thinner one can be used, and a grounding booth made of an inexpensive material, It is possible to use the bar 51 to reduce the manufacturing cost and facilitate the mounting of the ground wire.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. And will be included in the described technical idea.
