본 발명은 해저에 포설되는 케이블을 접속시키기 위한 해저 케이블의 접속장치에 관한 것으로 특히 수밀성이 우수하고 설치작업이 간편하며 케이블의 접속상태가 견고하게 되도록 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 a cable installed on the seabed, and more particularly, to a connecting device that is excellent in watertightness, easy installation work, and the connection state of the cable is firm. 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 도서지방사이의 통신수단 설치를 위하여 통신케이블을 해저에 포설하고 있는 실정이며 바다를 사이에 두고 있는 2개 이상의 섬, 또는 대륙간의 통신수단 연결도 해조를 이용하고 있다.In addition, in order to establish communication means between inland and island regions, communication cables are laid at the bottom of the sea, and two or more islands, or intercontinental communication means, which connect the sea, use seabirds.

이와 같은 케이블의 해저 포설은 육상설치에 비하여 많은 노력을 기울여야 하지만, 육상 설치에 비하여 안전성이 우수하고 장거리 설치가 가능하며 낙뢰나 태풍등으로부터 통신시설을 보호할 수 있기 때문에 해저 포설작업은 통신분야에서 널리 이용되고 있다.Submarine laying of such cable should take much effort compared to the installation of land, but the installation of the submarine is more effective than the land installation because the safety of the cable can be installed over long distances and the communication facilities can be protected from lightning or typhoons. It is widely used.

그러나 단거리에 통신수단을 설치할 경우에는 단선의 케이블을 직접 해저에 포설하고 양단을 각각의 통신수단에 연결할 수 있지만, 장거리의 경우 특히 십수킬로미터 이상 이격된 지역간의 연결은 양지역으로 2개이상의 케이블을 설치하고 이들 케이블을 해저에서 연결설치하여야만 했다.However, in case of installing communication means at 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, the connection between two or more kilometers is more than two cables. They had to install and connect these cables from the sea floor.

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(200M 이하)이며 심해에서는 이용할 수 없는 단점이 있다. 또, 상기의 대륙붕용에 있어서도, 수밀성이 우수하지 못하여 장기간 사용할 수 없게 되는 문제점이 있었으며 포설되는 접속장치는 용접등으로 조립되어있어서 고장수리가 불가능하였을 뿐만 아니라 부품의 재활용이 이루어지지 못하는 등의 폐단이 있었다.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 point, but some of the cable connection device for the seabed has been drawn out, most of the continental shelf (200M or less) has a disadvantage that can not be used in the deep sea. In addition, even in the above-mentioned continental shelf, there was a problem in that the watertightness was not excellent, so that it could not be used for a long time. 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.

상기와 같이 각 수밀수단과 케이블의 조립 및 연결작업이 완료되면, 각각의 하우징(1)(102)(2)(201)에 설치된 투입구(102)(103)(104)(202)를 통하여 각 하우징의 공간부분 수밀 콤파운드(36)를 충전시키고 상기 수밀 콤파운드(36)의 충전완료후 상기 각 투입구를 밀봉하며, 상기와 같이 하여 케이블의 연결 작업이 완료하면 이상태로 해저에 수장포설시킨다.When the assembly and connection work of each watertight means and the cable is completed as described above, each through the inlet (102) (103) (104) (202) installed in each of the housing (1) 102 (2) 201 After filling the watertight compound 36 of the space part of the housing and filling the watertight compound 36, the respective inlets are sealed, and when the connection work of the cable is completed as described above, the water is placed on the sea floor in this state.

상기와 같이 본 발명의 실시예에 의하면, 4단계의 수밀수단이 각 스페이서와 타이롯드에 의해 일정간격이 유지되면서 설치되고 이에 따라 케이블이 안정적이고 견고하게 접속연결되며 각 수밀수단의 조립수단에서 2단계의 수밀기능을 발휘하고 또 수밀 콤파운드에 의해 수밀 기능이 보강되며 각 하우징의 결합부분에 설치된 씰에 의해서 1차적인 수밀이 되는등 적어도 4단계 이상의 수밀이 이루어지므로 수밀효과가 우수하게 되고 이러한 수밀효과로 심해의 수천 KG/CM2 의 수압에서도 견뎌낼 수 있고 케이블의 접속 상태가 이완되거나 단락되는 일이 없게되어 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 predetermined interval by each spacer and tie rod, accordingly, the cable is connected stably and firmly, and the assembly means of each watertight means 2 Watertightness of the stage is achieved, watertightness is reinforced by the watertight compound, and the watertight effect is excellent because at least four levels of watertightness are achieved, such as the first watertightness by the seals installed at the joints of each housing. The effect is to 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 교체작업 등을 용이하게 할 수 있으나, 대저, 해저에 포설되는 접속장치(특히 수천 KM 이상의 심해일 경우)는 수십, 수백년간 포설된 상태로 있게되므로 고장수리의 경우는 그리 흔하지 않다.In addition, the cable can be easily dismantled and replaced when the cable is being replaced or repaired.However, the connection device installed on the bottom and the sea floor (especially in the deep sea of more than several thousand KM) has been installed for tens or hundreds of years. Troubleshooting is not so 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 있게 되는 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 characterized by lighting.
