In addition, the conductive connector 30 to be described later is fixed to the inner surface of the first elastic body 21 through the fixing part 31.

Particularly, in the case of the first elastic body 21, when the conductive wire 1a of the underground distribution line 1 is pressurized through the conductive wire connector 30, the first elastic body 21 can be supported so as to be firmly fixed and fixed to a predetermined portion. It is desirable to have a material property that can be accommodated.

In contrast, the second elastic body 22 is relatively softer than the first elastic body 21, and thus, when the second elastic body 22 surrounds the covering 1b of the underground distribution line 1, the first elastic body 21 Relatively more tightly compressed between the outer surface of the sheath (1b) and the inner surface of the second elastic body 22, so that the infiltration water from the outside can be blocked inherently, It is possible to prevent accidents due to electric short circuits.

In addition, in the case of the insulating material 20, the parts in contact with each other, unlike the case 10 is cut in a diagonal line rather than horizontal, which is the case in which the underground distribution line (1) inserted into the case 10 and the first elastic body 21 And when pressurized through the conductor connector 30, due to the thickness of the underground distribution line (1) is not tightly contacted with each other to generate a gap, the gap generated in this way to the gap while the incised portion is inclined It blocks the inflow of infiltrate water which can be introduced.

In addition, the conductive wire connector 30 is provided with a fixing portion 31 formed on the outer surface, and the fixing projections 32 formed on both ends of the inner surface, the fixing portion 31 to the inner surface of the first elastic body 21 is mediated It is a metal body having a semicircular cross section which is installed. Here, the fixing projection 32 is inserted into the inner side and bites the outer surface of the conducting wire (1a) which is in contact with each other to function to fix so that the disconnection state is not released.

In the embodiment according to the present invention, the wire connector 30 is insert-molded in the first elastic body 21 via a fixing part 31 having a 'T'-shaped cross section, which is only one embodiment. And, if necessary, it can be installed by various known methods.

As described above, the clamping bracket 40 is a well-known coupling tool for controlling folding and unfolding of the first and second semicircular portions 11 and 12, and is installed on the outer surface of the first semicircular portion 11. It consists of the hook part 41 and the fastening part 42 provided in the outer surface of the 2nd semi-circle part 12. As shown in FIG.

In addition, the installation position of the hook portion 41 and the fastening portion 42 can be modified as much as necessary.

In addition, since the clamping bracket 40 is already well known technology, a detailed description thereof will be omitted.

Referring to the use state of the present invention made of such a configuration as follows.

First, the 1st semi-circle part 11 and the 2nd semi-circle part 12 which comprise the case 10 are rotated about the hinge axis, and it develops.

Then, the conductive wire (1a) of the underground distribution line (1) to be connected to each other is seated on the inner surface of the conductive wire connector 30 fixed to the inner surface of the first semi-circular portion 11 by the insulating material 20, each Rotating the second semicircular portion 12 so that the conductive line 1a of the underground distribution line 1 can be wrapped by the second semicircular portion 12 in a state where the conductive line 1a of the underground distribution line 1 is brought into close contact with each other. Let it be.

As described above, when the second semicircular portion 12 is rotated to surround the underground distribution line 1, the outer surface of the conductive line 1a is inserted into the fixing protrusion 32 of the conductive line connector 30 to insert each conductive line 1a. It is electrically interconnected, and the sheath 1b of the underground distribution line 1 is hermetically sealed between the outer surface of the sheath 1b and the inner surface of the second elastic body 22 while the second elastic body 22 is compressed.

When the first semi-circular portion 11 and the second semi-circular portion 12 are folded by a hinge to form a circle, the first semi-circular portion 11 and the second semi-circular portion 12 are formed using a clamping bracket 40 composed of a hook portion 41 and a fastening portion 42. The first semi-circular portion 11 and the second semi-circular portion 12 is fixed so as not to open.

On the other hand, if you want to release the combined state for maintenance can be separated easily and simply by releasing in the reverse order of the method.

According to a preferred embodiment of the present invention, the underground distribution line (1) inserted through both ends of the case 10 can be easily and simply connected and released, the operation is very convenient, the underground distribution line ( Since the conductive wire 1a of 1) is buried and fixed, not only can the connection state between the underground distribution lines 1 be maintained steadily, but also the covering 1b of the underground distribution lines 1 is carried through the second elastic body 22. As it is hermetically wrapped and secured, there is an advantage of blocking the infiltration of water from the outside.

On the other hand, the present invention is based on the configuration described in Figures 1 to 3 described above, and the first elastic body 21 and the second elastic body 22 is a contact surface that is coupled to each other, that is, airtightness and water tightness at the interface In order to increase the structure of the site can be improved as follows.

For example, since the first elastic body 21 and the second elastic body 22 are made of synthetic rubber as described above, the flatness of both end faces thereof may be degraded, and the two end faces may be in contact with each other, that is, the interface plane. No matter how well adhered, there is no choice but to have a tiny gap.

Moreover, the structure according to the present invention is more so because it is assembled so as to form a circular tube by covering it in a folding manner by rotating it in a state where one end of the first elastic body 21 and the second elastic body 22 is hingedly fixed.

Accordingly, in the present invention, as shown in FIG. 4A, one outer peripheral surface of the first elastic body 21 and the second elastic body 22, that is, the first and second elastic bodies 21 and 22 are in contact with each other. On the outer circumferential surface of the end is formed an elongated concave in the longitudinal direction long groove 100 in the longitudinal direction at intervals with each end.

The plate magnet 110 is inserted into the long groove 100.

In this case, the plate magnet 110 should be inserted into the first elastic body 21 and inserted into the second elastic body 22 to have the opposite polarity.

Then, the two plate magnets 110 generate magnetic force with each other on the surface where both ends are in contact with each other, so that the attraction force is increased, and the end portions thinly left at both ends are finely opened by these adsorption forces, and thus perfectly perfectly. The close contact does not cause even a small gap.

In addition, there is little possibility, but even a very small amount of water penetrates, and the water penetrates to the conductively connected conductor connector 30 facing the conductor 1a so as to cause excessive electricity abnormality or short circuit. Can cause safety problems.

Therefore, the first and second elastic bodies 21 and 22 are formed in a radial direction at intervals with the wire connector 30 so as to collect even a small amount of water, and a collecting groove 120 recessed in a predetermined depth is formed. Is formed.

At this time, the collection groove 120 is preferably a rectangular shape, even if a small amount of water penetrates to block the flow so as not to flow toward the connector 30, and after a certain period of time is naturally dried by the internal heat.

In addition, for convenience of connection of the conductive wire 1a connected to the conductive wire connector 30, the stepped portion 130 having a predetermined height protrudes from the central length of the conductive wire connector 30 and is formed in a radial direction.

Therefore, the operator can simply connect the two conductors 1a exactly half while being caught by the step 130 simply by pushing the conductors 1a to the end.

As such, the insulated connector for protecting the buried underground distribution line according to the present invention has the advantage of improving the convenience of the conductor connection work while achieving more thorough airtightness and watertightness.
