종래의 접속 트레이는 광심선을 연결하기 위한 광점퍼코드가 지지되는 코드지지부를 중심으로 양측에 광심선의 여장을 수용하는 여장수용부로 이루어지는 것이 일반적이다. 이러한 종래의 접속 트레이는 광심선이 가입자별 또는 기능별로 정리되어 있지 않아 분배와 절체작업 및 유지보수 작업이 불편하며, 광심선의 보호, 점퍼코드 및 광 심선의 여장 정돈을 효율적으로 수행하지 못하는 단점이 있다.Conventionally, the connection tray is generally composed of an accommodating portion for accommodating the cuffs on both sides of the cord supporting portion on which the optical jumper cord for connecting the optical fiber is supported. Such conventional connection trays are inconvenient for distributing and switching work and maintenance work because the optical fiber lines are not organized for each subscriber or function, and it is a disadvantage that the protection of the optical fiber, the jumper cord and the arrangement of the optical fiber cable are not efficiently performed have.
특히, 종래의 저장함은 과다한 광심선의 수용으로 인하여 심선의 분리작업이 어렵고, 분리작업 시 다른 심선의 절단 및 밴딩에 의한 장애가 발생하는 요인이 된다. Particularly, in the conventional storage box, separation of the core wire is difficult due to the acceptance of an excessively large core wire, and other troubles are caused by cutting and bending of the other core wire during the separation operation.
한편, 미국 특허 제5,402,515호에는 커넥터와 어댑터 대신에 카드 형태의 트레이와 기계식 접속자를 사용하여 광섬유의 분배와 절체를 이루도록 한 광섬유 분배 시스템이 게시되어 있다. U.S. Patent No. 5,402,515 discloses an optical fiber distribution system in which a card-type tray and a mechanical connector are used instead of connectors and adapters to distribute and exchange optical fibers.
이 광섬유 분배 시스템에 의하면, 외부 캐비넷 또는 함체에 대하여 피벗 운동을 하도록 부착된 다수의 트레이를 구비한 내부 모듈들을 포함한다. This optical fiber distribution system includes internal modules with a plurality of trays attached to the outer cabinet or enclosure for pivotal movement.
각 트레이는 광섬유 정리부, 기계식 접속자를 포함하는 광심선 절체부, 그리고 점퍼 광심선 정리부를 구비한다. 트레이 내로 인입된 광섬유는 광심선 절체부의 기계식 접속자의 한 쪽에 연결되고, 점퍼 광심선 정리부에 저장되는 점퍼 광심선이 상기 기계식 접속자의 다른 쪽에 연결된다. 따라서, 상기 점퍼 광심선은 다른 내부 모듈의 트레이나 같은 모듈의 다른 트레이에서 인입 광케이블과 접속 가능하게 됨으로써, 광케이블간의 분배와, 절체가 이루어지게 된다. Each tray has an optical fiber gland portion, an optical core wire transfer portion including a mechanical connector, and a jumper optical core wire portion. The optical fiber drawn into the tray is connected to one side of the mechanical connector of the optical fiber transfer section and the jumper optical core wire stored in the jumper optical fiber line section is connected to the other side of the mechanical connector. Accordingly, the jumper optical core wire can be connected to the incoming optical cable from another tray of the same module of the other internal module, so that distribution and switching can be performed between the optical cables.
이러한 광섬유 분배시스템은 광심선정리부와 접속부가 동일평면상에 위치될 수 없으므로 상대적으로 분배시스템이 커지게 되는 문제점이 있으며, 점퍼광심선이 얽히기 쉽고, 외력에 의해 손상될 수 있다. This optical fiber distribution system has a problem that the distribution system becomes relatively large because the optical center design part and the connection part can not be located on the same plane, and the jumper optical core wires are easily entangled and damaged by external force.
한편, 국가 또는 광통신 사업자 마다 광심선의 개수가 다른 광케이블을 사용하고 있다. 또한 기존에 사용되던 광케이블과는 광심선의 개수와 다른 개수의 광심선을 구비한 광케이블로 교체하는 경우도 있다. 이와 같이 광심선의 수가 다른 케이블을 사용하는 경우, 광심선을 연결하기 위하여 사용되는 기계식 접속자의 광심선 접속부의 개수도 달라져야 한다.  On the other hand, optical cables with different numbers of optical fiber lines are used for each country or optical communication company. In some cases, the optical fiber is replaced with an optical fiber having a different number of optical fibers than the number of optical fibers used in the conventional optical fiber cable. If a cable with a different number of optical fibers is used, the number of optical fiber connections of the mechanical connector used to connect the optical fiber cable should also be changed.
이러한 광심선의 수가 다른 케이블을 사용하는 경우, 광심선을 연결하기 위한 트레이들을 호환성 있게 사용할 수 없다.  If the number of these fiber optic lines is different, the trays for connecting the optical fiber cables can not be used interchangeably.
특히, 일측의 트레이로부터 인접하는 트레이로의 광점프심선이 접속되는 경우, 광점프심선을 별도로 보호하기 위한 수단이 필요한데, 광점프심선이 많아지면 광점프심선과 트레이들과의 간섭이 상대적으로 심하게 된다. 트레이에 정리 및 접속된 하나의 광심선이 단락되는 경우, 손상된 광심선의 확인이 어렵고, 광심선이 인출되는 튜브를 용이하게 고정할 수 없다. 또한 광케이블의 광심선들의 분배에 따른 작업성은 다소 향상시킬 수 있으나 함체로부터의 광케이블의 이탈 시 이탈되지 않은 케이블의 광심선과 얽히게 되어, 광심선이 손상되는 문제점을 야기시키게 된다. Particularly, when the optical jump core line from one side of the tray to the adjacent tray is connected, means for separately protecting the optical jump core line is required. If the optical jump core line is large, the interference between the optical jump core and the trays becomes relatively severe do. In the case where a single optical fiber cable connected to the tray is short-circuited, it is difficult to confirm the damaged optical fiber cable, and the tube from which the optical fiber cable is drawn can not be easily fixed. In addition, the workability due to the distribution of the optical center lines of the optical cable can be somewhat improved, but is entangled with the optical center line of the cable which is not detached when the optical cable is detached from the housing.

상술한 바와 같이 구성된 본 발명의 적층형 광심선 저장함(10)은 복수개의 광심선들을 그 종류별로 분류할 수 있는데, 각각의 광심선(220)의 여장을 개별적으로 각 제1여장트레이(50)과 제 2여장트레이(60)에 권취하여 수용하고, 제1,2여장트레이(50)(60)으로부터 각각 인출된 광심선(220)은 상호 접속된 광접속튜브(250)가 어 광접속튜브저장부(42)에 개별적으로 지지된다. The multi-layer optical fiber storage box 10 of the present invention configured as described above can classify a plurality of optical fibers into different types, and each of the optical fiber cables 220 is individually connected to each of the first filament trays 50, The optical fiber cable 220 wound around the second filament trays 60 and drawn out from the first and second filament trays 50 and 60 are connected to each other through the optical connecting tube 250, (42).
광점프심선(230)의 여장 역시 그 종류에 따라 개별적으로 제 1,2여장트레이(50)(60)에 각각 권취되어 수용되고 이로부터 인출된 광점프심선은 점프광심선지지유닛(70)의 점프광심선가이드봉(71)에 가이드되어 광접속튜브저장트레이(40)들중의 하나로 연장되어 상술한 바와 같이 접속된다. The optical jump core wire 230 is wound around the first and second filament trays 50 and 60 individually according to the kind thereof and the optical jump core wire drawn from the first and second filament trays 50 and 60 is wound around the jump optical core wire supporting unit 70 Guided by the jump optical fiber guide rods 71 and extended to one of the optical connection tube storage trays 40 and connected as described above.
이러한 과정에서 상기 광심선을 감싸는 튜브(220)들은 상술한 바와 같이 광심선지지부(80)에 의해 제 1,2여장트레이(50)(60)들에 지지되거나 지지플레이트(31)에 형성된 튜브지지부(89))에 의해 견고하게 지지되므로 종래와 같이 튜브파지력의 저하로 광심선이 손상되는 것을 방지할 수 있다. In this process, the tubes 220 surrounding the optical fiber are supported by the first and second filament trays 50 and 60 by the optical center line support 80 as described above, (89)), it is possible to prevent the optical core wire from being damaged due to the lowering of the tube gripping force as in the conventional art.
특히, 본 발명에 따른 적층형 광심선 저장함(10)은 선택된 광접속튜브저장트레이(40)와 제 1,2여장트레이(50)(60)가 도 11 및 도 12에 도시된 바와 같이 펼쳐진 상태에서 상기 자세유지유닛의 제1,2,3커버부재(101)(102)(103)의 제1,2,3걸림돌기(91)(95) (97)을 상기 제 1,2,3지지홈(92)(96)(98)에 각각 결합한다. Particularly, the laminated optical fiber line storage box 10 according to the present invention is configured such that the selected optical fiber tube storage tray 40 and the first and second filament trays 50 and 60 are unfolded as shown in FIGS. 11 and 12 The first, second and third engaging protrusions 91, 95 and 97 of the first, second and third cover members 101, 102 and 103 of the posture maintaining unit are engaged with the first, (92), (96), and (98), respectively.
이와 같이 하면, 선택된 광접속튜브저장트레이(40)와 제 1,2여장트레이(50)(60)의 상부측에 위치되는 광접속튜브저장트레이(40)와 제 1,2여장트레이(50)(60)가 회동되는 것을 방지할 수 있다. The optical connection tube storage tray 40 and the first and second storage trays 50 and 50 located on the upper side of the selected optical connection tube storage tray 40 and the first and second storage trays 50 and 60, (60) can be prevented from rotating.
이렇게 정리된 광심선(220)들은 광심선들이 종류별로 따로 제1,2여장트레이(50)(60)들이 분류되어 수용되기 때문에 각 광심선들이 상호 엉키거나 꼬이는 것을 방지할 수 있고, 광점프심선(230)도 광점프심선가이드봉(71)에 의해 분리된 상태로 연장되기 때문에 추후에 광심선의 절체작업 등을 수행할 때, 작업자가 신속하게 작업을 수행할 수 있고, 작업 중 다른 광심선에 파손이 발생하는 것을 방지할 수 있다.Since the first and second filament trays 50 and 60 are sorted and accommodated separately by the optical fiber cables 220, the optical fiber cables 220 can prevent each optical fiber cable from being entangled or twisted, (230) is extended in a state of being separated by the optical jump core wire guide rods (71), it is possible for a worker to perform a work quickly when performing a switching operation of a cantilever beam later, It is possible to prevent breakage from occurring.
