본 발명은 해저에 포설되는 케이블을 접속시키기 위한 해저 케이블의 접속장치에 관한 것으로 특히 수밀성이 우수하고 설치작업이 간편하며 케이블의 접속상태가 견고하고 콤펙트화되도록 한 접속장치에 관한 것이다. 현금에 이르러 통신기술이 급진적으로 발달하고 있으며 특히 광케이블에 의한 통신수단이 비약적으로 발전하고 있는 실정에 있다.The present invention relates to a subsea cable connecting device for connecting the cable installed on the seabed, and more particularly to a connection device that is excellent in watertightness, easy installation work, and the connection state of the cable is robust and compact. The communication technology is radically developed with the arrival of cash, and in particular, the communication means by the optical cable is rapidly developing.

또한 내륙과 도서지방 사이의 통신수단 설치를 위하여 통신케이블을 해저에 포설하고 있는 실정이며 바다를 사이에 두고 있는 2개 이상의 섬, 또는 대륙간의 통신수단 연결도 해저를 이용하고 있다. 이와 같은 케이블의 해저 포설은 육상설치에 비하여 많으 노력을 기울여야 하지만, 육상 설치에 비하여 안전성이 우수하고 장거리 설치가 가능하며 낙뢰나 태풍등으로부터 통신시설을 보호할 수 있기 때문에 해저 포설작업은 통신분야에서 널리 이용되고 있다.In addition, the communication cable is installed on the seabed to install the communication means between the inland and the island region, and the connection between the two or more islands or the intercontinental communication means using the sea is also used. Submarine laying of such cable should take much more effort than land installation, but it is safer than long-term installation and can be installed over long distances and can protect communication facilities from lightning or typhoon. It is widely used.

그러나 단거리에 통신수단을 설치할 경우에는 단선의 케이블을 직접에 해저에 포설하고 양단을 각각의 통신수단에 연결할 수 있지만, 장거리의 경우 특히 십수킬로미터 이상 이격된 지역간의 연결은 단선만으로 설치가 곤란하기 때문에 양지역으로 2개이상의 케이블을 설치하고 이들 케이블을 해저에서 연결설치하여야만 했다.However, in case of installing communication means in short distance, cable of single wire can be installed directly on the sea floor and both ends can be connected to each communication means.However, in case of long distance, it is difficult to install only in case of connection between regions separated by more than ten kilometers. Two or more cables had to be installed in both locations and these cables had to be connected from the bottom.

따라서 해저에서 연결되는 2개 이상의 케이블을 안전성있고 견고하게 연결해야 하는 수단이 요구되고 있다. 한편, 상기와 같은 점을 고려하여 해저용 케이블 접속장치가 일부 인출된바 있으나, 대부분이 대륙붕용(수심200M 이하)이며 수밀성 보장이 어려워 심해에서는 이용할 수 없는 단점이 있다.Therefore, there is a need for a means to safely and securely connect two or more cables connected from the sea floor. On the other hand, in consideration of the above points, some of the submarine cable connection device has been drawn out, but most of the continental shelf (depth of the water 200M) and difficult to guarantee the water tightness has a disadvantage that can not be used in the deep sea.

또, 상기의 대륙붕용에 있어서도, 수밀성이 우수하지 못하여 장기간 사용할 수 없게 되는 문제점이 있었으며 포설된 접속장치는 용접등으로 조립되어 있어서 고장수리가 불가능 하였을 뿐만 아니라 부품의 재활용이 이루어지지 못하는 등의 폐단이 있었다.In addition, in the above-mentioned continental shelf, there was a problem that the watertightness was not excellent, so that it could not be used for a long time, and the installed connection device was assembled by welding or the like, which made it impossible to repair the malfunction, and also prevented the recycling of parts. There was this.

본 발명은 상기와 같은 점들을 고려하여 4단계의 수밀수단과 결합부분의 수밀수단을 완벽하게 하고 또 각 부분의 조립을 용이하게 할 수 있도록 되어 있으며 케이블의 연결을 견고하게 할 수 있다.The present invention is to make the watertight means of the four stages and the watertight means of the coupling portion in consideration of the above points and to facilitate the assembly of each part and to secure the connection of the cable.

It is retained and the junction box 3 is installed between the disk bodies 5. The second watertight means (B) is press-installed on the outer side of the first watertight means (A) and the locking ring jaw (13) is formed on both sides of the plate body (12) thereof, and the watertight seal (14) on one side thereof in the center portion. The supporter 15 and the ear holder 16 are fastened and installed, respectively, and a seal 17 is installed on the outer circumferential surface of the plate body 12, and the locking ring jaw 6 of the locking ring jaw 13 and the first watertight means A is provided. ) Is divided into two and the spacer 18 having a locking jaw (19) 191 is fixedly installed.

한편 하우징(1) 양단에 설치되는 커버 하우징(2)(201)에는 각각의 케이블(4)이 클램프(20)로 고정설치 되며 각 커버 하우징(2)(201)의 양단에는 제3수밀수단 (C)이 구비되고 상기의 케이블(4)의 와이어(401)는 상기 제2수밀수단(B)의 와이어 홀더(16)에 고정환설 되며 케이블(4)의 내심부만이 제1, 제2수밀수단(A)(B)의 중앙 수밀씰(7)(14)을 관통하여 상기 접속 내함(3)에서 연결된다.Meanwhile, each cable 4 is fixed to the cover housings 2 and 201 installed at both ends of the housing 1 by clamps 20, and third sealing means (3) is provided at both ends of each cover housing 2 and 201. C) is provided, and the wire 401 of the cable 4 is fixedly connected to the wire holder 16 of the second watertight means B, and only the inner core of the cable 4 is first and second watertight. It is connected in the junction box 3 through the central watertight seals 7 and 14 of the means (A) (B).

또 상기 제4수밀수단(C)은 수밀씰(21)과 씰커버(22)로 구성되어 있으며 이 수단은 커버 하우징(2)(201)의 끝단 케이블(4) 사이에 설치되어 1차적인 수밀기능을 갖게 된다.In addition, the fourth watertight means (C) is composed of a watertight seal (21) and the seal cover 22, this means is installed between the end of the cable (4) of the cover housing (2) 201 primary watertight It has a function.

상기와 같이 제3수밀수단(C)과 케이블(4)이 설치된 각각의 커버 하우징 (2) (201)은 상기 하우징(1)의 양단에 각각 체결 설치되며 이들 체결 부위에는 한쌍의 씰(23)이 교호로 설치 된다.As described above, each cover housing (2) 201 in which the third watertight means (C) and the cable (4) are installed is fastened to both ends of the housing (1), and a pair of seals (23) are provided at these fastening sites. This is installed alternately.

상기와 같이 각 수밀수단과 케이블의 조립 및 연결작업이 완료되면 각각의 하우징(1)(2)(201)에 설치된 투입구를 통하여 각 하우징의 공간부분 수밀 콤파울드 (24)를 충전시키고 상기 수밀 콤파운드(24)의 충전완료후 상기 각 투입구 밀봉하며, 상기와 같이 하여 케이블의 연결작업이 완료되면 이 상태로 해저에 수장포설 시킨다.When the assembly and connection work of each watertight means and cable is completed as described above, the space-part watertight compound 24 of each housing is filled through the inlets installed in the respective housings 1, 2, 201, and the watertight After the filling of the compound 24 is completed, the respective openings are sealed, and when the connection work of the cable is completed as described above, it is installed on the sea floor in this state.

상기와 같이 본 발명의 실시예에 의하면 4단계의 수밀수단이 스페이서와 타이롯드에 의해 일정간격이 유지되면서 설치되고 이에 따라 케이블이 안정적이고 견고하게 접속연결되며 각 수밀수단의 조립작업이 용이하게 될뿐만 아니라 각 수밀수단에서 2단계의 수밀기능을 발휘하고 또 수밀콤파운드에 의해 수밀 기능이 보강되며 각 하우징의 결합 부분에 설치된 씰에 의해서 1차적인 수밀이 되는등 적어도 4단계 이상의 수밀이 이루어 지므로 수밀효과가 우수하게 되며 이러한 수밀효과로 심해의 수천 KG/CM2의 수압에서도 견뎌낼 수 있고 케이블의 접속 상태가 이완되거나 단락되는 일이 없게 되어 수명이 장구하게 된다.According to the embodiment of the present invention as described above, the watertight means of step 4 is installed while maintaining a constant interval by the spacer and the tie rod, and thus the cable is connected stably and firmly, and the assembly work of each watertight means will be easy. In addition, watertightness is achieved by at least four levels of watertightness, including two levels of watertightness in each watertight means, watertight compound reinforced by watertightness, and primary watertightness by seals installed at the joints of each housing. The effect is excellent and the watertight effect can withstand the water pressure of thousands of KG / CM2 in the deep sea, and the cable connection is not loosened or shorted, resulting in long life.

또 케이블의 교체작업시나 고장수리시에도 용이하게 분해하여 교체작업등을 용이하게 할수 있으나 대저해저에 포설되는 접속장치(특히 수천 KM 이상의 심해일 경우)는 수십 수백년간 포설된 상태로 있게 되므로 고장수리의 경우는 그다지 흔하지 않다.In addition, the cable can be easily dismantled and replaced when the cable is repaired or repaired. However, the connection device (especially in the deep sea over thousands of KM) will be installed for several hundreds of years. The case is not very common.

이상과 같은 본 발명은 종래의 해저 케이블 접속장치에 비하여 구조와 구성이 간단하면서도 다단계의 수밀기능에 의한 수밀효과가 우수하며 또 연결 및 조립작업등이 간편하며 조립등의 작업공수를 절감할 수 있고 비교적 콤팩트 하여 취급이 용이 하게되는 점등의 특징을 지닌 것이다.As described above, the present invention is simpler in structure and configuration than the conventional submarine cable connection device, and has excellent watertightness effect due to the multi-stage watertight function, and is easy to connect and assemble. It is compact and has the feature of lighting that is easy to handle.
