본 발명은 특히 통신케이블의 연결부위의 침수여부를 외부에서 식별할 수 있게 한 케이불접속부의 침수식별창치에 관한 것이다.In particular, the present invention relates to a submerged identification window of a cabling connection unit that enables external identification of the inundation of a connection part of a communication cable.

상기 통신케이블의 접속부위는 지하 수미터에 설치된 콘크리트 맨홀내에 설치되거나, 지하에 매설된 통신케이블관내에 집중적으로 설치되어 있다.The connection portion of the communication cable is installed in a concrete manhole installed in several meters underground or concentrated in a communication cable pipe buried underground.

이와 같이, 상기 통신케이블은 일정길이로 제한하여 일정거리를 두고 콘크리트 맨홀을 구축하여 통신케이블의 연결부위를 설치하므로써 점검 등 통신선로의 수리나 설치작업이 용이하다. 그러나, 이러한 접속부는 지하에 매설되어 있기 때문에 지하수나 우기때 침수가 용이하여 정기적으로 이 접속부위를 점검하여야 하며 맨홀 전체가 침수될 경우에는 맨홀 내부의 물을 긴급 제거한 다음 이 접속부위의 침수여부를 선별하여 침수된 접속부위는 다시 해체하여 다시 연결작업을 하여야 하는바, 이때 이 연결부위의 내부에 침수되었는지의여부를 판별하기가 용이하지 않아 각 통신선로의 이상 유무를 일일이 시험하거나 아니면 맨홀내에 설치된모든 통신선로의 연결부위를 해체하여 다시 연결작업을 하였으므로 불필요한 교체공사는 물론 작업능룰이저하되고 공사의 지연, 불필요한 예산낭비 등의 결점이 있었다.In this way, the communication cable is limited to a certain length by building a concrete manhole at a certain distance to install the connection portion of the communication cable, it is easy to repair or install the communication line, such as inspection. However, because these connections are buried underground, it is easy to inundate during the groundwater or rainy season, so check this connection regularly. If the entire manhole is flooded, remove the water inside the manhole and then check whether it is inundated. Selected and submerged connection parts should be dismantled and reconnected again. At this time, it is not easy to determine whether the connection is submerged inside the connection parts. As the connection parts of all communication lines were dismantled and reconnected, there were defects such as unnecessary replacement work, deterioration of work performance rules, delay in construction, and unnecessary waste of budget.

통신선로의 연결작업은 알려진 바와 같이 알미늄관으로 케이블연결부를 감싼 다음 그 외피에 열수축관으로 가열 수축시켜 연결부를 완전 밀폐하는 공정으로 이루어져 있어 작업공정이 까다롭고 설치비가 고가이다.As the connection work of communication line is known, the cable connection part is wrapped with aluminum tube, and then the heat shrinkage tube is shrunk with a heat shrink tube to completely seal the connection part, which makes the work process difficult and expensive to install.

그러나, 이러한 연결부위도 장시간 물에 침수되어 있거나, 연결부의 부실한 공사로 인해 이 연결을 통해 물이 침투되는 경우가 있으며, 장시간 침수상태로 놓아 두면 케이블 전체가 침수되어 더 많은 예산과 작업시간이 소요되므로 항상 긴급 복구하여야만 하였다. 그러나, 이러한 침수된 접속부는 통신선로를 통해 각선로마다 일일이 이상 유무를 시험하거나 접속부를 해체해 보지 않은 이상 침수여부를 확인할 수 없었다.However, this connection part may be inundated with water for a long time, or water may penetrate through this connection due to poor construction of the connection part, and if left in the inundated state for a long time, the whole cable is flooded, which requires more budget and work time. As a result, emergency recovery was always required. However, such a flooded connection was not able to check whether the flooded or not, unless the communication line has been tested for abnormality or dismantled.

그러므로 종래에는 더 이상 피해 확산을 방지하기 위하여 침수된 맨홀내의 모든 케이불접속부는 이상 여부를 확인하지 않고 전부 해체하여 다시 접속작업을 하는 비능률적인 작업양태로 진행되어 왔다. 이로 인한소요 예산낭비는 물론 작업시간 지연으로 통신두절 또는 통신불량상태가 발생될 뿐 아니라 작업인력의 소모가 극심하였던 실정이다.Therefore, conventionally, in order to prevent further spread of damage, all the cable connection parts in the submerged manhole have been proceeded to an inefficient working mode of dismantling and reconnecting without checking for any abnormality. As a result, not only waste of budget but also delay of work time resulted in communication interruption or communication failure, and the consumption of work manpower was severe.

본 발명은 상기 제반 결점을 해결하고자 케이블접속부의 침수여부를 외부에서 이를 간단히 감지하여 침수된 접속부만을 선별하여 해체 수리하게 하므로 작업시간을 단축하고 인력낭비, 예산낭비 등을 절감하고자한 것이다.In order to solve the above-mentioned drawbacks, the present invention aims to shorten the work time and reduce man-hours, budget waste, and the like by simply detecting the inundation of the cable connection from the outside and selecting and dismantling and repairing only the submerged connection.

이하, 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.

본 발명은 2개의 도전판 사이에 흡수도가 양호한 절연지를 설치하고 2개의 도전판은 도선으로 연결하여 열수축관 외부로 인출시켜 2개의 도전판이 절연지에 의해 절연되어 있거나, 절연지가 수분을 함유하여 2개의 도전판이 도통되는지의 여부를 감지하므로써 접속부의 내부의 침수여부를 식별하고자 한 것이다.The present invention provides an insulating paper having good absorbency between the two conductive plates, and the two conductive plates are connected by conducting wires and drawn out of the heat shrink tube so that the two conductive plates are insulated by the insulating paper, or the insulating paper contains moisture. The purpose of the present invention is to identify whether the two conductive plates are conductive or not, so as to identify the inundation of the inside of the connection portion.

2개의 도전판(10)(20)은 0.2mm 정도의 동박판을 사용하는 것이 유리하며 동박판 몸체는 구멍(11)(21)을 다수 천공하여 2개의 도전판 사이의 절연지(30)가 외부로 노출되는 표면적을 넓히므로 절연지의 수분흡수를 더욱 용이하게 한다. 절연지(30)은 흡수도가 양호한 식물성 부직포나 지재로 구성하는 것이 바람직하며 2개의 도전판(10)(20)은 각 도선(40)(50)에 의하여 연결되며 각 도선(40)(50)은 외부에 부도체인 절연재로 피막되고 후렉시불한 것이 유리하다. 각 도선(40)(50)은 도전성 소재로 된 동관(60) 내부를 관통 설치하되 2개중 하나의 도선(40)은 동관(60)에 접속하고 또 다른 도선(50)은 동관(60)의 선단 외부로 인출하여 노출시킨다.The two conductive plates 10 and 20 are advantageously to use a copper foil of about 0.2mm, and the copper foil body has a plurality of holes 11 and 21 to perforate the insulating paper 30 between the two conductive plates. As the surface area exposed is increased, the moisture absorption of the insulating paper becomes easier. The insulating paper 30 is preferably composed of a vegetable nonwoven fabric or a paper having good absorbency, and the two conductive plates 10 and 20 are connected by the respective conductive wires 40 and 50, and the conductive wires 40 and 50 are respectively. Silver is advantageously coated with a non-conducting insulating material and flexible. Each conductor 40, 50 is installed through a copper tube 60 made of a conductive material, one of the two conductors 40 is connected to the copper tube 60, and another conductor 50 of the copper tube 60 Draw it out of the tip and expose it.

동관(60)은 그 단부에 나조(61)를 형성하여 캡(62)을 나착시키게 하고 동관(60) 내부에는 내열성소재(70)를 충전시켜 동관과 도선과의 열전도를 방지하여 동관이 가열될때(후에 설명항) 도선이 용융되는 것을 방지하며 동관(60)의 외면에는 열수축소재(80)로 피막한다.The copper tube 60 forms a screw thread 61 at an end thereof to allow the cap 62 to be screwed in, and the copper tube 60 is filled with a heat resistant material 70 to prevent heat conduction between the copper tube and the conductive wires when the copper tube is heated. (Refer to the following section) The wire is prevented from melting and the outer surface of the copper tube 60 is coated with a heat shrinkable material (80).

본 발명은 제 4도 표시와 같이 접속부(A)의 내부에 2개의 도전판이 접속케이블(B) 표면에 접면되게 한다음 알미늄관(C)을 씌우고, 동관(60)은 외부로 노출되게 하고 열수축관(D)을 알미늄관(C) 의부로 감싼다음 가열하면 열수축관(D)은 알미늄관(C) 표면에 밀착 수축된다.According to the present invention, as shown in FIG. 4, two conductive plates are brought into contact with the surface of the connection cable B in the interior of the connection portion A, and then the aluminum tube C is covered, and the copper tube 60 is exposed to the outside and the heat shrinkage. When the tube (D) is wrapped around the aluminum tube (C) and heated, the heat shrink tube (D) closely contracts on the surface of the aluminum tube (C).

이때, 동관(60)의 표면에 감겨 있는 열수축소재(80)가 동시에 녹아 알미늄관의 의포면에 밀착 수축되는열수축관(D)과 열체로 용융되므로 동관(60)이 열수축관(D)의 외부로 돌출되더라도 그 연결부위는 완전 용융 접합되어 일체가 되기 때문에 돌출된 동관의 틈새는 완전 차단된다.At this time, the heat-shrinkable material 80 wound on the surface of the copper tube 60 melts at the same time and melts into a heat-shrink tube (D) and a thermal body that closely contracts on the surface of the aluminum tube, so that the copper tube 60 is external to the heat-shrink tube (D). Even if it protrudes as the connection part is completely melt-bonded and integrated, the gap of the protruding copper tube is completely blocked.

동관(60)의 선단에는 나조(61)가 있어 캡(62)을 씌우며 이 캡은 도선을 보호한다. 동관(60)내의 내열성소재(80)는 통신케이블의 접속부 설치시 열수축관(D)을 알미늄관 표면에 밀착 수축시키기 위하여 가열하게되는 바 이때 이와 인접된 동관이 열을 받게 되므로 가열된 동관에 의해 도선이 용용되는 것을 방지하며 또한편 접속부위가 침수될 경우 동관을 통해 물이 침투되는 것을 방지한다.At the distal end of the copper tube 60, there is a thread 61, which covers the cap 62, which protects the conductors. The heat-resistant material 80 in the copper tube 60 is heated in order to closely contract the heat shrink tube D on the surface of the aluminum tube when the connection portion of the communication cable is installed. In this case, the copper tube adjacent to the copper tube receives heat and is heated by the heated copper tube. It prevents the lead wire from melting and also prevents water from penetrating through the copper pipe when the piece connection part is flooded.

이와 같이 각 통신케이블의 접속부위마다 본 장치를 설치하여 두면 접속부위 내부에 밀착된 2개의 도전판을 절연지를 사이에 두고 절연되어 있다가 침수현상이 발생하면 절연지는 물을 흡수하여 결국 2개의 도전판을 도통하게 되므로 이 접속부의 침수여부를 알고자 할 때에는 캡을 열고 외부에서 공지의 감지기(테스타기또는 메가)로 동관과 도선을 각각 접촉 측정하면 2개의 도선이 도통 또는 절연상태의 여부를 감지함으로써통신케이블 접속부위 내부의 침수여부를 식별할 수가 있는 것이다.In this way, if the device is installed at each connection part of each communication cable, the insulating paper is insulated between two conductive plates in contact with the inside of the connection part. Since the plate is conducting, if you want to know whether or not the connection part is inundated, open the cap and measure the copper tube and the conductor by using a known detector (tester or mega) from the outside to detect whether the two conductors are conductive or insulated. It is possible to identify whether the communication cable is flooded inside.

이상과 같이 본 발명은 외부에서 간단히 접속부 내부의 침수여부를 식별할 수 있으므로 각 통신선로마다이상 유무를 확인할 필요가 없으므로 종래 각 선로마다 통화시험을 하는 번거러움이 없으며 침수된 접속부만을 선별하여 교체작업을 할 수 있으므로 수리작업이 용이하고 작업시간을 절감하므로써, 통신장애 또는통신두절의 시간을 줄일 수 있으며 침수된 접속부위만 선별하여 작업하므로 경제적 이점이 크다.As described above, the present invention can easily identify the inundation of the inside of the connection from the outside, so there is no need to check the abnormality of each communication line, so there is no hassle of conducting a call test for each conventional line, and only replaces the flooded connection and selects the replacement work. As it can be done, repair work is easy and work time can be saved, so it is possible to reduce the time of communication failure or communication breakdown, and it is economical because it works by selecting only the flooded connection part.
