Description

{Ground wire connection terminal for earth bar}

The present invention relates to a grounding line connection terminal for a grounding bar, and more particularly, to a grounding line connection terminal for grounding an electric current generated from various electric facilities such as a steel tower and a pole, To a grounding wire connection terminal for a grounding rod.

As it is known, as the ground rod becomes larger and the length becomes longer, the grounding resistance decreases exponentially. Such a grounding rod is buried in the ground and connected to a ground wire connected to various electric facilities such as a steel tower and a pole, And discharges to the ground.

Conventionally, a grounding bar used in the above-mentioned applications is buried in at least one ground in order to match the grounding resistance value required in various electric facilities such as a steel tower, a pole, etc., when the grounding rod is embedded in the ground. A grounding line is connected to the top of the grounding rod, As shown in FIG.

In this case, since the ground wire and the sleeve are additionally used, there is a drawback in that the material cost and the construction cost are expensive.

In addition, a configuration of a ground terminal for connecting a ground wire to the upper end of the ground bar is configured to connect the ground wire to both sides of the ground terminal.

In the construction of the ground terminal, which is most similar to the present invention, when the ground terminal is constructed, the top end of the ground terminal is sharpened so as to be easily peeled, and a hole is drilled horizontally in the upper portion of the ground terminal, Respectively.

When connecting more than one grounding bar in parallel, the grounding terminal constructed as described above should be stripped at the point where the grounding terminal is connected to the grounding line in order to make the copper line constituting the grounding line contact with the grounding terminal.

When the grounding wire partially peeled off the cover is inserted into the hole formed in the upper portion of the grounding terminal as described above, it is impossible to directly insert the copper wire stripped from the cover, so the hole must be passed from one side of the grounding wire .

As described above, in order to allow the hole formed in the ground terminal to pass through from the portion where the cover is not peeled off to the ground wire, the diameter of the hole formed in the ground terminal must be larger than the diameter.

Then, although the ground wire is easy to pass through the hole formed in the ground terminal, a lot of clearance is generated between the copper wire stripped of the ground wire and the hole formed in the ground terminal.

If a clearance is formed between the copper wire and the hole of the ground terminal as described above, the connection state between the ground terminal and the ground wire can not be surely maintained. As a result, not only the desired ground resistance value can be obtained, So that the function of the ground bar is deteriorated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a method for connecting a ground wire to a ground wire connection terminal for a ground bar in series or in parallel and connecting a ground wire to a ground wire connection terminal for a ground bar, It is possible to prevent the water from penetrating and to improve the grounding force by making it possible to be stuck with the connection terminal fitting hole of the grounding bar by making interference with it, so that the copper wire of the grounding wire and the grounding line connection terminal can be completely bonded to the connection terminal fitting hole without any clearance. And a ground wire connection terminal for a ground bar.

In order to accomplish the above object, the grounding line connection terminal for a grounding bar according to the present invention is constructed in a tapered shape so that the grounding line connection terminal can be easily coupled to the connection terminal fitting hole formed at the upper end of the grounding rod,

Particularly, one or two copper wire connecting parts for connecting the copper wire of the ground wire in the longitudinal direction are formed on one side of the ground wire connecting terminal, or copper wire connecting parts for connecting the copper wires of the ground wire are formed on both sides of the ground wire connecting terminal. .

According to the present invention as described above, since the copper wire of the ground wire and the ground wire connection terminal can be embedded in the connection terminal fitting hole of the ground bar deeply in the longitudinal direction, the ground wire connection terminal and the connection terminal fitting hole of the ground wire can be perfectly There is an advantage that it is adhered to each other, and moisture penetration into the connection terminal fitting hole of the grounding bar can be prevented, and the grounding area can be formed to be wide.

The construction of the ground wire connection terminal for a ground bar according to the present invention will be described in detail as follows.

When the ground wire connection terminal 1 for the grounding bar according to the present invention is constructed, the joining strength of the grounding wire connection terminal 1 is increased as it is easily and deeply coupled with the connection terminal fitting hole 11 formed in the upper end of the grounding bar 10 The ground line connection terminal 1 is configured to be tapered,

When the ground wire connecting terminal 1 is joined to the connecting terminal fitting hole 11 formed at the upper end of the grounding bar so that the copper wire 21 of the ground wire 20 can be seated and stuck together, (2) are formed so as to overlap one another in the longitudinal direction so that one copper wire coupling portion (2) is formed in the longitudinal direction or the ground wire (20) is connected to the grounding bar (10) And,

When the ground wire connecting terminal 1 is inserted into the connecting terminal fitting hole 11 formed at the upper end of the grounding rod, the diameter of the ground wire connecting terminal 1 is reduced and elasticity is imparted to the ground wire connecting terminal 1, (3) is formed on the inner side of the body (2)

In another configuration of the present invention, copper wire connecting portions 2 and 2 'are formed on both sides of the ground wire connecting terminal 1 so that the grounding bar 10 can be connected to the ground wire 20 in parallel.
