In general, in various buildings (including facilities), a grounding net is installed and constructed to discharge the lightning introduced through the lightning rod or the surge generated from various electric facilities to the ground. In other words, the grounding network protects the human body by suppressing the rise of the ground potential and contact/step voltage within the allowable value from external lightning strikes or ground faults in electrical equipment, while providing a low impedance path for accidental current to protect various devices and human bodies. To be installed and constructed.

Depending on the installation location, the ground network is connected to the ground in a mesh type by a bare copper wire at the basement and adjacent parts of the building structure, and an outdoor ground (main ground network) formed by inserting several ground rods, and within the building. It is divided into a structure ground (building ground network) that is connected to a building reinforcement or steel frame for grounding of various electric devices (outlets/lights, etc.) to be installed and finally connected to an outdoor ground network.

Indoor grounding uses reinforcing bars or steel frames constructed in a building as a grounding electrode, and ground wires connected to specific places such as reinforcing bars or steel frames in buildings through electrical boxes (including concrete wall boxes) embedded in walls or ceilings through concrete placement. After connecting to the ground terminal of various electric devices, the ground network was finally connected to the outdoor ground.

However, in the indoor grounding network according to the prior art, a ground wire connecting each electric box is additionally used for the grounding of various electric devices fixed to the electric box installed in the building, so that the power line and the ground wire are simultaneously introduced through the pipe. This is difficult and cumbersome, requiring a large amount of labor, as well as an increase in working hours, and in particular, there is a problem in that the construction cost for building a ground network increases as a large amount of ground wire must be used.

1 is a view showing a wire coupling connector for indoor grounding of a building according to an embodiment of the present invention, and FIG. 2 is a view showing a state in which the wire coupling connector for indoor grounding of a building shown in FIG. 1 is connected to a reinforced structure 3 is a view showing an enlarged part of a state in which the wire coupling connector for grounding indoors of the building shown in FIG. 2 is connected to the reinforced structure.

1 to 3, the wire coupling connector 10 for indoor grounding of a building according to an embodiment of the present invention may be made of a metal material having excellent conductivity, for example, copper.

The wire connection connector 10 for indoor grounding of such a building is made of a clamp structure and is connected with a reinforcing bar binding tool 11 and a reinforcing bar binding tool 11 to open the entrance side through the grip of a finger to bind to the reinforcing bar 1 And a plurality of wire connector 12 to which the ground wire 2 is connected.

The reinforcing bar binding tool 11 is for easily binding to the reinforcing bar 1 using the lever principle, and after a pair of binding portions 111 and a pair of binding portions 111 are bound to the reinforcing bar (1). Between a pair of pressing parts 112 extending integrally at the ends, a connecting part 113 for rotatably connecting the pair of pressing parts 112 through a hinge pin, and a pair of pressing parts 112 It is installed on and includes an elastic portion 114 that provides an elastic force so that the pair of pressing portions 112 are engaged with each other.

On the other hand, in general, the reinforcing bar (1) has a protrusion protruding outward on the outer circumferential surface for reinforcement of rigidity. When the reinforcing bar binding tool 11 is coupled to the outer circumferential surface of the reinforcing bar 1, the reinforcing bar binding tool ( The inner surface of 11) is not in close contact with the outer circumferential surface of the reinforcing bar (1), but only a part of the reinforcing bar 1 is in contact, thereby increasing the contact resistance, which may interfere with stable grounding.

Accordingly, a groove (not shown) into which the protrusion is inserted may be further formed in the pair of binding portions 111 that are bound to the reinforcing bar 1 to correspond to the protrusions formed on the outer circumferential surface of the reinforcing bar 1. The groove may have a shape corresponding to the protrusion so that the protrusion is male and female. Through this, it is possible to improve the connection force between the pair of binding portions 111 and the reinforcing bar (1).

4 is a view showing to explain the wire connector according to the present invention, (a) is a view viewed from the top of the wire coupling connector, (b) is a view viewed from the bottom.

1 and 4, a total of 4 wire connection ports 12 are integrally connected to the reinforcing bar binding tool 11, each of two up and down. That is, a total of four are connected to the pair of pressing portions 112, each two.

As shown in FIG. 4, as shown in FIG. 4, a total of four wires are formed so that the ground wires of wires having different thicknesses, for example, 6SQ, 10SQ, 2.5SQ, and 4SQ, are independently connected.

The wire connector 12 electrically connects the ground wire 2 and the reinforcing bar 1 of various thicknesses.

The ground wire (2) is connected when manufacturing the wire coupling connector (10) for indoor grounding of a building.

First, the covering of one end of the ground wire 2 is removed to partially expose the conductive wire. Thereafter, the exposed conductor of the ground wire 2 is inserted into the wire connector 12, and the outer surface of the wire connector 12 is crimped and fixed to electrically connect the ground wire 2 to the wire connector 12.

The wire connector 12 has a'C type' or a circular (tubular) structure, and the ground wire 2 inserted therein is crimped to be fixed. It is made of the same material integrally with the reinforcing bars (11). That is, the wire connector 12 may be made of copper, similar to the reinforcing bar binding tool 11.

One end of the ground wire 2 is crimped and fixed to the wire connector 12, and the other end thereof is formed through a through hole (not shown) formed on one side of the electric box 3 (or electric panel box). ) Is introduced into the interior of the electrical box 3 (or electrical panel box) to form a ground network.
