The condenser 70 has a cooling case 71 and a cooler 72 to remove moisture inside the distribution case 10.

The cooling case 71 has a space formed therein and is installed at a lower portion of the inner rear surface of the distribution case casing 10. At this time, since the cooling case 71 is provided at the lower portion of the distribution case 10, the condensed water does not come into contact with the entire distribution portion 41 of the distribution front 40, thereby preventing a short circuit caused by the condensed water. Further, since the cooling case 71 is located above the drain hole 11b of the distribution case main body 11, the condensed water is quickly discharged.

The cooler 72 includes a cooler feeder 72a that is installed outside the distribution box case 10 and produces cool air when the cooling signal is received from the humidity sensor 80, A cool air supply line 72b that is connected to the cooling case 71 through the air blower 11 and is drawn out from the cooling case 71 and passes through the distribution case main body 11 to enter the cool air supplier 72a, And a cool air discharge line 72c through which cool air having passed through the case 71 is discharged. In the present embodiment, the structure for producing cold air of the cold air supplier 72a is a well-known technology, and a person having ordinary knowledge can easily implement it.

6 to 8 are views for explaining the operation of a submarine distribution line in a subdivision according to the present invention. Referring to FIGS. 6 to 8, As follows.

First, the connection method of the distribution line 40 of the distribution line DL will be described.

The distribution wire DL is inserted into the airtightness member 20 and flows into the distribution case main body 11.

The distribution wire DL is inserted into the second inlet hole 52b of the distribution wire bending portion 52 of the distribution wire support member 50 and the distribution wire DL drawn out from the second inlet hole 52b, Is inserted into the first inlet hole (52a) of the distribution wire folding part (52).

At this time, if the distribution wire DL is inserted into the second inlet hole 52b or the first inlet hole 52a while rotating the distribution wire bending portion 52 or moving the distribution wire bending portion 52 up and down, The distribution wire DL can be inserted into the second inlet hole 52b or the first inlet hole 52a.

Subsequently, after the distribution wire DL is inserted into the distribution wire inlet hole 42a1 of the distribution wire guide portion 42a, the distribution wire (DL) is connected to the distribution wire 41 at a position where the distribution wire DL is easily connected DL.

3, the moving stationary fixture 61 of the stationary support member 60 is inserted into the moving part fastening hole 51a of the moving part 51 of the distribution wire support member 50 and the fastening hole 51a of the distribution wire guide part 42a Is inserted into the distribution wire guide portion fixing hole (42a3) to fix the moving portion (51) of the distribution wire support member (50).

The supporting body 62 of the stationary support member 60 is inserted into the head part fastening hole 61a1 of the moving stationary body 61 so as to insert the support body 62 of the stationary support body 60, (62) protrudes upward so that the support body (62) supports the distribution wire folding part (52).

Subsequently, the distribution wire (DL) located in the distribution area (41) is connected to the distribution area (41) so as to conduct electricity.

7, the distribution wire leading-out hole 11a of the distribution case main body 11 and the airtightness member 20 of the distribution case main body 11 are separated from each other, as shown in FIG. 7, when the distribution wire DL is kept bent by the distribution wire fold- The water does not move in the direction of the distribution front 40, so that a short circuit by water can be prevented.

On the other hand, the humidity sensor 80 measures the internal humidity of the distribution case 10, and when the measured humidity value is higher than a predetermined reference value, the cooling signal to generate cold air to the cold air supplier 72a of the condenser 70 . Then, the cold air supply device 72a produces cold air and supplies it to the cooling case 71, and the air that has cooled the cooling case 71 returns to the cold air supply device 72a again.

At this time, when the cooling case 71 is cooled, the moisture present in the distribution case case 10 is condensed in the cooling case 71, and the condensed water falls downward as shown in FIG. 8 and is discharged.
