Description

광케이블 접속함의 광케이블 고정장치{Optical cable fixing device of optical cable connecting box}Optical cable fixing device of optical cable connecting box}

본 발명은 광케이블 접속함에 관한 것으로, 더욱 상세하게는 광케이블 접속함으로 인입된 광케이블을 하부 함체에 고정하기 위한 광케이블 접속함의 광케이블 고정장치에 관한 것이다.The present invention relates to an optical cable splice box, and more particularly, to an optical cable fixing device of an optical cable splice box for fixing an optical cable introduced into the optical cable splice into the lower housing.

일반적으로 광케이블은 광신호를 전송하는 케이블로서, 전기신호를 전송하는 케이블과는 달리 많은 양의 정보를 손실 없이 신속히 전송할 수 있다.In general, an optical cable is a cable for transmitting an optical signal, and unlike a cable for transmitting an electrical signal, a large amount of information can be quickly transmitted without loss.

또한 광케이블은 다수의 광케이블 클러스터의 집합으로 이루어지고 각 광케이블 클러스터는 다수의 광섬유의 집합으로 이루어진다.In addition, the optical cable is composed of a plurality of optical cable clusters, each optical cable cluster is composed of a plurality of optical fibers.

상기 광케이블은 제조업체에서 무한정 긴 길이로 제조할 수 없기 때문에 통상 2Km 정도의 길이로 제조되어 드럼에 감겨지며, 따라서 광케이블을 먼 거리까지 설치하기 위해서는 중간 중간에서 이를 연결하여야 한다.Since the optical cable cannot be manufactured by the manufacturer for an indefinite long length, the optical cable is usually manufactured in a length of about 2 Km and wound on a drum.

이렇게 광케이블을 중간에서 연결하거나 또는 광케이블을 분기하기 위해 광케이블 접속함이 사용되며, 상기와 같은 광케이블 접속함은 크게 나누어 광케이블이 인입되어 접속되는 부분이 되는 하부 함체와, 상기 하부 함체에 결합되어 밀폐 공간을 형성하고 필요시 개방이 가능한 상부함체와, 상기 하부 함체내에 장착되는 하나 이상의 트레이 등으로 이루어져 있다.The optical cable junction box is used to connect the optical cable in the middle or to branch the optical cable. The optical cable junction box is divided into a lower enclosure and a sealed space coupled to the lower enclosure to be a part to which the optical cable is inserted and connected. The upper housing and the one or more trays that are mounted in the lower housing and the like can be formed and opened if necessary.

그리고 상기 하부 함체의 양측에는 광케이블을 하부 함체 내부로 인입하기 위한 복수의 광케이블 인입구가 형성되어 있고 양측의 광케이블 인입구를 통해 인입된 광케이블은 트레이 부분에서 서로 연결 접속되거나 분기된다.A plurality of optical cable inlets are formed at both sides of the lower housing to introduce the optical cables into the lower housing, and the optical cables introduced through the optical cable inlets on both sides are connected or branched to each other at the tray part.

상기와 같은 광케이블 접속함에서 광케이블 인입구로 인입된 광케이블은 케이블 자체의 장력 등에 의해 항상 하부 함체의 바깥측으로 당겨지는 힘을 받게 되며, 이러한 힘으로 부터 광케이블의 연결부위를 보호하기 위해 광케이블 접속함에는 인입된 광케이블을 하부 함체에 고정하기 위한 고정수단이 구비되어야 한다.In the optical cable junction box, the optical cable introduced into the optical cable inlet is always pulled to the outside of the lower housing by the tension of the cable itself, and in order to protect the connection portion of the optical cable from the force, Fixing means for securing the finished optical cable to the lower housing shall be provided.

한편 종래에는 하부 함체 내의 광케이블 인입구 부분에 광케이블의 고정을 위한 스크류를 설치하고 스크류를 조이면 그 선단이 광케이블의 외표면에 밀착되면서 하부 함체에 고정되게 하였다.Meanwhile, in the related art, when a screw for fixing an optical cable is installed at an inlet portion of an optical cable in the lower enclosure, and a screw is tightened, the tip of the optical cable is fixed to the lower enclosure while being in close contact with the outer surface of the optical cable.

그러나 상기와 같은 종래의 광케이블 접속함은 스크류의 조임력에 의해 광케이블이 고정되는 구조이어서 스크류를 조이는 강한 힘에 의해 광케이블이 과도하게 찌그러지면서 압축되어 변형을 일으키게 되고, 때로는 광케이블의 외피부분이 손상되는 경우도 발생한다.However, the conventional optical cable junction box is a structure in which the optical cable is fixed by the tightening force of the screw, so that the optical cable is excessively crushed and compressed by the strong force tightening the screw, causing deformation, and sometimes the outer part of the optical cable is damaged. Also occurs.

또한 상기와 같이 광케이블이 과도하게 압축되면 광케이블을 구성하는 광섬유의 성능에도 좋지 않은 영향을 미치게 된다.In addition, if the optical cable is excessively compressed as described above, it will adversely affect the performance of the optical fiber constituting the optical cable.

본 발명의 목적은 하부 함체 내로 인입된 광케이블을 과도하게 압축시키지 않고 간편하게 하부 함체에 고정시킬 수 있는 장치를 제공하기 위한 것이다.It is an object of the present invention to provide an apparatus which can be simply fixed to the lower enclosure without excessively compressing the optical cable introduced into the lower enclosure.

상기와 같은 목적을 달성하기 위한 본 발명의 실시예에 따라 하부 함체의 양측에 광케이블 인입방향과 직교하는 방향으로 형성된 격벽과, 상기 격벽으로 부터 안쪽으로 돌출 형성되고 하부 함체 내로 인입된 광케이블이 얹혀지는 케이블 받침편과, 상기 케이블 받침편과 그 위에 얹혀진 광케이블을 감싸 광케이블을 케이블 받침편에 고정시키는 호스밴드로 구성된 것을 특징으로 하는 광케이블 접속함의 광케이블 고정장치가 제공된다.According to an embodiment of the present invention for achieving the above object, a partition wall formed in a direction orthogonal to the optical cable insertion direction on both sides of the lower housing, and is formed projecting inward from the partition wall and the optical cable drawn into the lower housing is placed There is provided an optical cable fixing device of an optical cable junction box, comprising a cable support piece, and a hose band surrounding the cable support piece and the optical cable mounted thereon to fix the optical cable to the cable support piece.

상기 케이블 받침편에는 광케이블의 외피에 접속하는 복수의 돌기가 형성되어 있고 상기 하부 함체에는 호스밴드의 스크류가 삽입되는 스크류 피난홈이 형성되어 있다.The cable support piece is provided with a plurality of protrusions connected to the outer shell of the optical cable, and the lower housing is formed with a screw evacuation groove into which the screw of the hose band is inserted.

본 발명은 스크류의 선단을 광케이블의 외피에 직접 접속시켜 조이는 종래 장치와는 달리 광케이블을 호스밴드로 감싸 하부 함체에 고정시키도록 되어 있기 때문에 종래와 같이 광케이블이 찌그러져 변형되거나 외피부분이 손상되는 일이 없게 되고, 광케이블이 과도하게 압축됨에 따라 야기되는 광케이블의 성능 저하를 방지할 수 있는 효과가 있다.In the present invention, unlike the conventional device that connects the tip of the screw directly to the outer shell of the optical cable and tightens the optical cable to be fixed to the lower housing by wrapping the optical cable with a hose band, the optical cable is crushed and deformed or damaged. There is no effect, and there is an effect that can prevent the performance degradation of the optical cable caused by the excessive compression of the optical cable.

상기 하부 함체(1)의 내부 양측에는 광케이블의 인입방향과 직교하는 방향으로 하부 함체(1)를 구획하는 격벽(2)이 설치되어 있으며, 이들 격벽(2)은 상기 인입구 가스켓(12)의 후방에 위치한다.Both inner sides of the lower housing 1 are provided with partitions 2 for partitioning the lower enclosure 1 in a direction orthogonal to the inlet direction of the optical cable, and these partitions 2 are rear of the inlet gasket 12. Located in

또한 상기 격벽(2)에는 안쪽을 향해 돌출된 복수개의 케이블 받침편(3)이 일체로 형성되어 있으며, 이들 케이블 받침편(3)은 각 인입구 가스켓(12)을 통해 인입된 광케이블(13)이 일직선상으로 얹혀질 수 있는 위치에 형성되어 있다.In addition, a plurality of cable support pieces 3 protruding inwardly are integrally formed in the partition wall 2, and these cable support pieces 3 include an optical cable 13 introduced through each inlet gasket 12. It is formed at a position where it can be placed in a straight line.

상기 케이블 받침편(3)은 상면과 저면이 모두 원호형을 이루며, 상면에는 광케이블(13)이 얹혀져 고정된다.The cable support piece 3 has an upper surface and a bottom surface in an arc shape, and an optical cable 13 is mounted on and fixed to the upper surface.

또한 상기 케이블 받침편(3)의 상면에는 광케이블(13)의 고정력을 향상시키 기 위해 광케이블(13)의 외피에 접속하는 복수의 돌기(4)를 형성할 수도 있다.In addition, a plurality of projections 4 may be formed on the upper surface of the cable support piece 3 to connect to the shell of the optical cable 13 in order to improve the fixing force of the optical cable 13.

상기 케이블 받침편(3)에 얹혀진 광케이블(13)은 광케이블 받침편(3)의 저면과 광케이블(13)의 외피를 감싸는 형태로 결합되는 호스밴드(5)에 의해 광케이블 받침편(3)에 일체형으로 고정된다.The optical cable 13 mounted on the cable support piece 3 is integrally formed with the optical cable support piece 3 by a hose band 5 which is coupled to surround the bottom surface of the optical cable support piece 3 and the sheath of the optical cable 13. Is fixed.

또 상기 호스밴드(5)에는 스크류(6)가 결합되어 스크류(6)를 조임에 따라 호스밴드(5)는 그 내경이 축소된다.In addition, as the screw 6 is coupled to the hose band 5 and tightens the screw 6, the inner diameter of the hose band 5 is reduced.

상기 케이블 받침편(3)의 인접한 위치에는 호스밴드(5)의 스크류(6)가 삽입될 수 있는 크기의 스크류 피난홈(7)이 형성되어 있다.Adjacent positions of the cable support piece 3 are formed with a screw evacuation groove 7 of a size into which the screw 6 of the hose band 5 can be inserted.

상기와 같은 본 발명의 광케이블 고정장치에 의해 광케이블을 고정하는 과정을 설명한다.The process of fixing the optical cable by the optical cable fixing device of the present invention as described above will be described.

먼저 하부 함체(1) 내로 인입된 광케이블(13)을 격벽(2)에 형성된 광케이블 받침편(3) 위에 올려놓고 광케이블 받침편(3)과 그 위에 얹혀진 광케이블(13)을 감싸는 형태로 호스밴드(5)를 결합한 후 스크류(6)를 조여주면 호스벤드(5)의 직경이 축소되면서 호스밴드(5)의 내경면이 케이블 받침편(3)의 저면 및 광케이블(13)의 외표면과 접속하게 된다.First, the optical cable 13 drawn into the lower housing 1 is placed on the optical cable support piece 3 formed on the partition wall 2, and the hose band is formed so as to surround the optical cable support piece 3 and the optical cable 13 mounted thereon. 5) After tightening the screw 6, the diameter of the hose bend 5 is reduced so that the inner diameter of the hose band 5 is connected to the bottom surface of the cable support 3 and the outer surface of the optical cable 13. do.

또한 상기와 같은 상태에서 스크류(6)를 더욱 조여주면 스크류의 조임력에 의해 광케이블(13)이 약간 압축되면서 케이블 받침편(3)에 밀착 고정되며, 이때 케이블 받침편(3)에 형성된 돌기(4)는 광케이블(13)의 외표면과 선접촉을 하면서 광케이블(13)과 케이블 받침편(5)의 결속력을 더욱 증가시킨다.In addition, when the screw 6 is further tightened in the above state, the optical cable 13 is slightly compressed by the tightening force of the screw, thereby being tightly fixed to the cable support piece 3, and the protrusions 4 formed on the cable support piece 3 are fixed. ) Further increases the binding force between the optical cable 13 and the cable support piece 5 while making linear contact with the outer surface of the optical cable 13.

한편 상기와 같이 광케이블(13)이 케이블 받침편(5)에 얹혀져 고정된 상태에 서는 광케이블(13)에 강력한 당김력이 작용하는 경우에도 케이블 받침편(3)에 결합된 호스밴드(5)가 하부 함체(1)에 형성된 격벽(2)에 걸려 이동이 불가능하므로 광케이블(13)은 하부 함체(1)의 바깥측 방향으로 당겨지지 않게 된다.On the other hand, when the optical cable 13 is mounted on the cable support piece 5 and fixed as described above, even when a strong pulling force is applied to the optical cable 13, the hose band 5 coupled to the cable support piece 3 is The optical cable 13 is not pulled toward the outer side of the lower housing 1 because it cannot be moved by being caught by the partition wall 2 formed in the lower housing 1.

그리고 상기와 같이 호스밴드(5)에 의해 광케이블(13)을 케이블 받침편(3)에 묶어 고정한 후 스크류(6)가 하부 함체(1)에 형성된 스크류 피난홈(7)에 삽입되도고 위치시키면 광케이블(13)에 당기는 힘 또는 미는 힘이 작용하는 경우에도 스크류 피난홈(7)에 삽입된 스크류(6)에 의해 호스밴드(5)의 이동이 제한되므로 광케이블(13)은 더욱 견고한 고정상태를 유지하게 된다.When the optical cable 13 is bundled and fixed to the cable support piece 3 by the hose band 5 as described above, the screw 6 is inserted into the screw evacuation groove 7 formed in the lower housing 1 and positioned thereon. Even when a pulling force or a pushing force is applied to the optical cable 13, the movement of the hose band 5 is limited by the screw 6 inserted into the screw evacuation groove 7, so that the optical cable 13 is more firmly fixed. Will be maintained.
