Consisting of an alarm 50, according to this, when leakage or leakage of electricity in the apartment house occurs, it can be quickly maintained by warning to the outside, and the distribution line L can be fixed more stably, as well as between the clamps 10. The extension work is very easy and the work is convenient.

The clamp 10 is divided into a pedestal 11 and a cover 12 to form a triangular shape when combined with each other, and functions to bite and fix the distribution line L disposed in a triangular shape inside.

The clamp 10 is mounted on a mount 100 installed on a wall of an apartment house, and an earth leakage alarm 50 electrically connected to the clamp 10 and the mount 100 is installed.

The clamp 10 is manufactured in an arc shape so that the inside can surround the circumferential surface of the distribution line L.

In the clamp 10, pin holes 11a and 12a are integrally formed so that the binding pin 32 of the fixture 30 can be inserted and detached.

When the clamp 10 is coupled with the fixture 30 in a state in which the lower surface of the cover 12 is abutted to the upper surface of the base 11 to form a triangular structure, the base 11 and the cover 12 They are fixed to each other, and conversely, when the fixture 30 is separated, the pedestal 11 and the cover 12 are separated from each other.

The clamp 10 is a structure that can be expanded, and this will be described in more detail as follows.

Based on the pin hole 11a formed in the pedestal 11, a protrusion 11b and a groove 11c are formed integrally on the left and right sides, respectively, and a rib groove 11d in front and rear of the groove 11c It is formed integrally.

Ribs 12b are integrally formed on the upper surface of the cover 12 so as to be spaced apart in the front-rear direction.

In addition, the protrusion 11b, the rib groove 11d, and the rib 12b are provided with holes so that the clamping pin 40 can be inserted therethrough.

When the clamp 10 is to be expanded in parallel, the protrusion 11b of the other clamp is inserted into the groove 11c of the clamp 10 and interconnected.

When the clamping pin 40 is inserted through the clamping pin 40 in the interconnected state as described above, the two clamps form an integral structure via the clamping pin 40, so that the extension work is very convenient.

In particular, since the neighboring clamp 10 can be interconnected via the protrusion 11b and the groove 11c, the rib groove 11d, and the rib 12b, even a beginner, not a skilled worker, can easily and conveniently perform extension work. There is an advantage in that workability is further improved.

Giving a function to prevent shaking, the binding pin 32 is disposed radially around the spacer 31 and is inserted and detachably inserted into the pin holes 11a and 12a, respectively.

Here, the binding pin 32 is manufactured integrally with the spacer 31.

For example, in a state in which the pedestal 11 and the cover 12 are coupled to each other, the binding pins 32 of the fixture 30 are formed with pin holes 11a and 12a formed in the pedestal 11 and the cover 12, respectively. When inserted, the base 11 and the cover 12 are fixed to each other by this. On the contrary, if the binding pin 32 of the fixture 30 is separated from the pin holes 11a and 12a, the base 11 and the cover (12) are separated from each other.

The clamp binding pin 40 is inserted through the protrusion 11b and the groove 11c, the rib groove 11d, and the rib 12b are mutually coupled to form an integral type to regulate their separation and coupling. do.

Accordingly, in the present invention, since all of the neighboring clamps 10 can be connected with one clamp binding pin 40, the working time can be drastically reduced, and accordingly, the working efficiency is further improved.

Referring to FIG. 3, in the leakage alarm 50, one of the two terminals is electrically connected to the clamp 10, and the other is electrically connected to the cradle 100 to detect when a leakage current occurs and a warning sound to the outside. It has a function of discharging, and accordingly, facility management can perform maintenance immediately.

Hereinafter, the operation of the leakage monitoring system for each section of the indoor electricity for an apartment house according to the present invention will be described.

First, the distribution line (L) is arranged in a single or triangular shape inside the pedestal 11 constituting the clamp 10, and then the cover 12 is covered and fixed by biting the distribution line L, and the pedestal 11 is a holder Settled in (100).

As described above, in a state where the distribution line L is fixed by the clamp 10, the pedestal 11 and the cover 12 are fixed so that they are not separated from each other using the fixture 30.

In more detail, when the fixture 30 is coupled to the clamp 10, the spacer 31 is intervened between the distribution lines L to reduce the gap between the distribution lines L and the rubber pad 20. Then, the binding pin 32 integral with the spacer 31 is inserted into the pin holes 11a and 12a of the clamp 10.

Therefore, by coupling the fixture 30 to the clamp 10 as described above, the pedestal 11 and the cover 12 can be easily fixed, thereby reducing the working time and maximizing the convenience of work.
