그리고, 본 발명을 설명함에 있어서, 관련된 공지기능 혹은 구성에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우 그 상세한 설명을 생략한다.
In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

도 1 내지 도 3을 참조하면, 본 발명에 따른 지중배전선 보호절연 커넥터는, 케이스(10), 절연재(20), 도선연결구(30), 클램핑금구(40)로 구성되어, 양단을 통해 삽입된 도선(1a)과 피복선(1b)으로 구성된 지중배전선(1)을 전기적으로 상호 연결한다.
1 to 3, the underground distribution line protective insulating connector according to the present invention, the case 10, the insulating material 20, the conductor connector 30, the clamping bracket 40 is inserted through both ends, The underground distribution line 1 composed of the conducting wire 1a and the covering line 1b is electrically connected to each other.

상기 케이스(10)는 금속 또는 합성수지재로 이루어진 공지의 중공관으로서, 본 실시 예의 경우 반원형의 단면을 갖는 제1반원부(11)와 제2반원부(12)로 분할형성되며, 힌지를 매개로 절첩 및 전개가능하게 형성되어 내측으로 삽입된 지중배전선(1)의 도선(1a)과 피복선(1b)을 감싸 외력으로부터 지중배전선(1)을 보호하는 기능을 한다.The case 10 is a well-known hollow tube made of a metal or a synthetic resin material. In this embodiment, the case 10 is divided into a first semicircular portion 11 and a second semicircular portion 12 having a semicircular cross section, and a hinge is provided. It functions to protect the underground distribution line 1 from external forces by enclosing the conductive line 1a and the covering line 1b of the underground distribution line 1 inserted inwardly and being developed to be folded and developed.

또한, 상기 케이스(10) 즉, 제1반원부(11)와 제2반원부(12)에는 이후에 설명될 클램핑금구(40)를 구성하는 걸이부(41)와 체결부(42)가 각각 설치되어 제1·2반원부(11,12)의 절첩 및 전개를 단속하게 된다.
In addition, the case 10, that is, the first semi-circular portion 11 and the second semi-circular portion 12, the hook portion 41 and the fastening portion 42 constituting the clamping bracket 40 to be described later, respectively, respectively. It is provided to interrupt the folding and unfolding of the 1st and 2nd semi-circular parts 11 and 12.

상기 절연재(20)는 공지의 합성고무로서, 반원형의 제1탄성체(21)와, 제1탄성체(21)의 양단에 설치되는 제2탄성체(22)로 구성되어 케이스(10) 즉, 제1반원부(11)와 제2반원부(12)의 내면에 열융착되어 고정된다. The insulating material 20 is a known synthetic rubber, and is composed of a semi-circular first elastic body 21 and a second elastic body 22 provided at both ends of the first elastic body 21. The inner surface of the semi-circular portion 11 and the second semi-circular portion 12 is heat-sealed and fixed.

상기 제1탄성체(21)의 내면에는 이후에 설명될 도선연결구(30)가 고정부(31)를 매개로 고정된다. 특히 제1탄성체(21)의 경우 도선연결구(30)를 매개로 지중배전선(1)의 도선(1a)를 가압할 때에 견실하게 물어 고정할 수 있도록 지지가 가능하면서도 일정부분을 탄성적으로 수용되도록 할 수 있는 재질적인 특성을 갖추고 있는 것이 바람직하다.The conductive connector 30, which will be described later, is fixed to the inner surface of the first elastic body 21 through the fixing part 31. In particular, 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 buried and to receive a predetermined portion elastically. It is desirable to have the material characteristic to be able to do it.

그에 반해, 상기 제2탄성체(22)는 제1탄성체(21)에 비해 상대적으로 소프트하며, 따라서 지중배전선(1)의 피복(1b)을 제2탄성체(22)가 감싸게 되면 제1탄성체(21)에 비해 상대적으로 더 압착되면서 피복(1b)의 외면과 제2탄성체(22)의 내면 사이를 더욱더 기밀하게 밀착되므로, 외부로부터의 침투수에 유입을 원천적으로 차단할 수 있어 침투수의 유입으로 인한 전기합선에 따른 사고를 미연에 방지할 수 있게 되는 것이다.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.

나아가, 상기 절연재(20)의 경우 케이스(10)와는 다르게 서로 접하는 부위가 수평이 아닌 사선으로 절개되어 있는데, 이는 내측으로 삽입된 지중배전선(1)을 케이스(10)와 제1탄성체(21) 및 도선연결구(30)를 매개로 가압할 때에 지중배전선(1)의 굵기로 인해 서로 단접하지 못하고 미세하게 벌어져 틈을 발생하게 되는데, 이와 같이 발생된 틈을 사선으로 절개된 부분이 압착되면서 틈으로 유입될 수 있는 침투수의 유입을 원천적으로 차단하게 된다.
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.

상기 도선연결구(30)는 외면에 형성되는 고정부(31)와, 내면 양단부에 형성되는 고정돌기(32)를 갖추고서, 제1탄성체(21)의 내면에 고정부(31)를 매개로 설치되는 반원형의 단면을 갖는 금속체이다. 여기서, 고정돌기(32)는 내측으로 삽입되어 서로 단접되어 있는 도선(1a)의 외면을 물어 단접 상태가 해제되지 않도록 고정하는 기능을 한다.The conductive wire connector 30 has a fixing part 31 formed on the outer surface and a fixing protrusion 32 formed at both ends of the inner surface thereof, and installed on the inner surface of the first elastic body 21 via the fixing part 31. It is a metal body which has a semicircular cross section. Here, the fixing projection 32 is inserted into the inner side and bites the outer surface of the conductive wire (1a) which is in contact with each other to function to fix so that the disconnection state is not released.

본 실시 예의 경우, 상기 도선연결구(30)는 T자형 단면을 갖는 고정부(31)를 매개로 제1탄성체(21)에 인서트 성형되는데, 이는 어디까지나 하나의 실시 예에 불하며, 필요에 따라 공지의 다양한 방법으로 설치할 수 있다.
In the present embodiment, the wire connector 30 is insert-molded in the first elastic body 21 via the fixing portion 31 having a T-shaped cross section, which is not limited to one embodiment as necessary. It can be installed by various known methods.

상기 클램핑금구(40)는 앞서 언급한 바와 같이, 제1·2반원부(11,12)의 절첩 및 전개를 단속하는 공지의 결합구로서, 제1반원부(11)의 외면에 설치되는 걸이부(41)와, 제2반원부(12)의 외면에 설치되는 체결부(42)로 구성된다. As described above, the clamping bracket 40 is a known coupling tool for clamping down the folding and unfolding of the first and second semi-circular portions 11 and 12, and is provided on the outer surface of the first semi-circular portion 11. The part 41 and the fastening part 42 provided in the outer surface of the 2nd semi-circular part 12 are comprised.

상기 걸이부(41)와 체결부(42)의 설치위치는 필요에 따라 얼마든지 변형될 수 있다.The installation position of the hook portion 41 and the fastening portion 42 may be modified as much as necessary.

상기 클램핑금구(40)는 이미 널리 공지된 기술이므로, 이에 대한 상세한 설명은 생략하도록 한다.
Since the clamping bracket 40 is already well known, a detailed description thereof will be omitted.

Let it be.

상기와 같이 제2반원부(12)를 회동시켜 지중배전선(1)를 감싸게 될 경우, 도선(1a)의 외면은 도선연결구(30)의 고정돌기(32)가 삽입되면서 각 도선(1a)을 전기적으로 상호 연결하게 되고, 지중배전선(1)의 피복(1b)은 제2탄성체(22)가 압축되면서 피복(1b)의 외면과 제2탄성체(22)의 내면 사이를 기밀하게 밀폐하게 된다.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.
