Branch holders(20) are inserted into both ends of the optical cable(30), and bushings(40) are assembled in between the branch holders(20) and the connector protect caps(50), whereby the release of the single-core connectors(60) from the connector protect cap(50) is prevented by the branch holders(20) and the bushings(40).

Description

광점퍼 케이블Optical jumper cable

본 발명은 광점퍼 케이블에 관한 것으로, 특히 광케이블의 양단에 융착 접속점 없이 바로 커넥터를 취부하여 접속손실을 제거함과 동시에 중앙 집중적 관리가 가능하도록 한 광점퍼 케이블에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical jumper cable, and more particularly, to an optical jumper cable capable of providing centralized management while eliminating connection loss by directly attaching a connector to both ends of an optical cable without fusion splicing.

일반적으로 광케이블이란 광파이버케이블(Optical Fiber Cable)이라고도 불리는 광통신용 케이블을 말하며 석영 등을 소재로 한 가는 실같은 것을 몇백 가닥씩 묶어 케이블을 만든 것이며, 광파이버는 광대역, 저손실, 무요도, 경량 등의 특징을 갖고 있기 때문에 그 적용범위가 넓혀지고 있다.In general, an optical cable is an optical communication cable, also called an optical fiber cable, and is made of several hundred strands of thin thread made of quartz, etc. Because it has a wide range of applications.

한편 광케이블은 보통 일정 구간마다 광증폭기 및 함체를 접속 설치하는데 있어 그 접속방법을 종래는 전문 기술자의 수작업에 의존해 융착접속기(Fusion Splicer)라는 고가의 정밀장치를 이용해 현장내에서 광케이블 양단에 편단코드를 사용하여 융착 접속하는 방법을 사용하였다.On the other hand, optical cables usually connect and install optical amplifiers and enclosures at regular intervals.However, the connection method is conventionally relying on the manual work of a professional technician to use one-sided cords on both ends of the optical cable in the field using expensive precision equipment called Fusion Splicer. The method of fusion splicing was used.

이에 따라 접속시간이 길고 지속적인 외부전력의 공급이 필요한 데다 한 번 이루어진 부분은 다시 접속할 수 없어 광케이블 잇는 데 최대 걸림돌로 작용해 왔다.As a result, connection time is long and continuous external power supply is required, and once made parts cannot be reconnected, which has been the biggest obstacle to connecting optical cables.

본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위해 창안된 것으로, 광케이블에 커넥터를 분기 접속시켜 융착접속 없이도 커넥터를 통하여 접속 가능케 하여 접속손실을 제거하고, 현장시공 및 운용시 시간적 경제적 손실을 대폭 향상시킬 수 있는 광점퍼 케이블 접속장치를 제공함에 그 목적이 있다.The present invention was devised to solve the problems of the prior art as described above, by connecting the connector to the optical cable to be connected through the connector without fusion splicing to eliminate the connection loss, greatly reduced the time and economic losses in the field construction and operation It is an object of the present invention to provide an optical jumper cable connection device that can be improved.

상기의 목적을 달성하기 위한 본 발명의 구체적인 수단은, 광케이블의 양단에 분기부 홀더를 삽착하고, 이 분기부 흘더에 부싱을 조립하고, 이 부싱을 단심커넥터를 보호하기 위한 커넥터 보호용 캡의 일단에 고정하고, 이 커넥터 보호용 캡의 타단에 포설을 위한 풀링부를 설치한 것을 특징으로 한다.Specific means of the present invention for achieving the above object is to insert a branch holder at both ends of the optical cable, to assemble the bushing in this branch holder, the bushing to one end of the connector protection cap for protecting the single-core connector It is fixed, and the other end of the connector protective cap is provided with a pulling portion for installation.

이하, 첨부된 도면을 참조하여 본 발명의 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

제1도에 도시된 바와 같이 광케이블(30)의 양단에 분기부 홀더(20)가 삽착되어 있고, 이 분기부 홀더(20)에 부싱(40)이 조립되고, 이 부싱(40)은 단심커넥터(60)를 보호하기 위한 커넥터 보호용 캡(50)의 일단에 고정되며, 이 커넥터 보호용 캡(50)의 타단에 포설을 위한 풀링부(70)가 설치된 구성이다.As shown in FIG. 1, branch holders 20 are inserted at both ends of the optical cable 30. A bushing 40 is assembled to the branch holder 20, and the bushing 40 is a single core connector. It is fixed to one end of the connector protection cap 50 for protecting the 60, the other end of the connector protection cap 50 is a configuration in which a pulling portion 70 for installation is installed.

상기 부싱(40)은 제3도에서와 같이 상하 분할된 한 쌍의 부싱부(41A,41B)로 구성되고, 그 외주면에 상기 커넥터 보호용 캡(50)에 나사 조립되기 위한 수나사(42)가 형성되어 있고, 또 그 중심부의 일측면에 제2도의 상기 분기부 홀더(20)의 환형홈(21)의 일측면에 다수개 형성된 삽입홈(21a)에 끼워맞춤되는 돌기(43)가 형성되어 있다.The bushing 40 is composed of a pair of bushing portions 41A and 41B divided up and down as shown in FIG. 3, and an external thread 42 for screwing the connector protection cap 50 is formed on the outer circumferential surface thereof. In addition, a projection 43 is formed on one side of the central portion thereof and fits into a plurality of insertion grooves 21a formed on one side of the annular groove 21 of the branch holder 20 in FIG. .

이같이 광케이블(30)의 양단에 커넥터(60)가 취부되는 단심부와 광케이블(30)에서 단심부로 분기되는 분기부로 구성함으로써 단심부는 각각의 광심선(10) 끝단에 광커넥터(60)가 취부된 구조가 되고, 분기부는 광케이블(30) 외피의 탈피로 인한 심선의 손상, 보호 및 광케이블(30)의 외피를 잡아주어 풀링부(70)를 이용한 포설시 단심코드부의 이탈을 방지할 수 있다.As such, the single core part includes a single core part for attaching the connector 60 to both ends of the optical cable 30 and a branching part for branching from the optical cable 30 to the single core part, and thus the optical connector 60 is attached to the end of each optical core wire 10. It becomes a structure, the branch portion can prevent the damage to the core wires due to the peeling of the outer sheath of the optical cable 30 and the outer sheath of the optical cable 30 to prevent the detachment of the single core cord portion during installation using the pulling portion 70.

따라서 광점퍼케이블은 시험실과 각 장비실간의 접속을 광커넥터(60)로 접속가능함으로써 종래 융착접속으로 인한 손실을 방지할 수 있고, 운용자가 손쉽게 운용이 가능하며, 각 단심광커넥터(60)에 코드번호를 부여하게 되면 심선 식별을 용이하게 할 수 있는 부가적인 이점도 있다.Therefore, the optical jumper cable can connect the connection between the test room and each equipment room with the optical connector 60, thereby preventing the loss due to the conventional fusion splicing, and the operator can easily operate the cord. Numbering also has the added benefit of facilitating core identification.

상술한 바와 같이 본 발명에 의하면 광케이블부와 단심코드부를 연결 유지할 수 있도록 그 사이에 분기부 홀더를 설치함과 동시에 부싱을 통하여 커넥터 보호용 캡에 조립됨으로써 종래와 같이 수작업에 의한 융착작업이 불필요하며, 접속손실이 제거되고, 현장시공 및 운용시 시간적 손실을 대폭 향상시킬 수 있는 장점이 있다.As described above, according to the present invention, a branch holder is installed therebetween so as to maintain the connection between the optical cable portion and the single-core cord portion, and at the same time, it is assembled to the connector protection cap through the bushing, thereby eliminating the need for manual welding. The connection loss is eliminated, and there is an advantage that can greatly improve the time loss in the field construction and operation.
