Abstract

A connector for cables with different diameters is provided to improve resistance for various environmental pollutions, to prevent voltage leakage, and to endure repeated mechanical stress. A connector for cables with different diameters includes a cable of a large diameter(2a), a cable of a small diameter(2b), a body housing(3), cable inlets(5a,5b), a cable insulator(6), a connection sleeve(4), connection grooves(7a,7b), and neutral lines(8a,8b). The cables are connected in a straight line and are surrounded by an outer sheath(1). The body housing is made of rubber. The cable inlets having different diameters are formed at both sides of the body housing. The cable insulator covers the connection ends of the cables of different diameters. The connection sleeve where the cables with different diameters are connected to each other has the connection grooves formed at both sides in correspondence to the cables. The neutral lines are connected to each other by a clamp(9) at the outside of the body housing.

본 발명은 직경이 서로 다른 이형 케이블을 직선 접속할 수 있는 접속재에 관한 것으로, 더욱 상세하게는 이형 케이블 접속시 오접속에 따른 접속재 손상을 방지하면서 시공성이 용이한 이형 케이블 직선 접속재에 관한 것이다.The present invention relates to a connecting member capable of linearly connecting release cables having different diameters, and more particularly, to a release cable linear connecting member which is easily workable while preventing damage to the connecting member due to a wrong connection when connecting a release cable.

22.9㎸ 대용량 배전방식에 경우 전력구와 관로의 케이블 선종 운영규격이 직경이 다른 이종 케이블로 되어 있을 때, 예를 들어 직경이 325㎟와 600㎟의 케이블 들을 서로 접속시킬 때 한 개의 직선 접속재 하우징과 별도의 케이블 아답터를 이용하여 직선 접속을 실행하고 있었다.22.9㎸ In the case of large-capacity distribution method, when the cable type operating standard of power port and pipe line is made of heterogeneous cables with different diameters, for example, when connecting cables with diameters of 325 mm2 and 600 mm2, A straight line connection was made using the cable adapter.

그러나 종래 상기와 같이 이종 케이블을 서로 접속할 때 케이블 절연부의 연결체인 직선 접속재 하우징은 다음과 같은 문제점들이 제기되어 왔다.However, when connecting heterogeneous cables to each other as described above, the following problems have been raised in the linear connector housing, which is a connector of the cable insulation.

① 접속재 하우징과 아답터, 케이블이 서로 별개의 부품에서 오시공에 의한 불량 발생이 크며,① In case of connecting material housing, adapter and cable, the defects caused by mis-installation are large.

② 직선 접속재 하우징이 1개의 구조보다 전압누설 계면이 늘어나게 되어 불량 발생 요인이 되고,② The linear leakage housing has more voltage leakage interface than one structure, which causes the failure.

③ 접속재 하우징과 아답터, 케이블이 별개의 부품이어서 시공 공차를 고려하여 접속재부의 길이를 길게 설계하여야 하는 폐단 및,(3) Closed end and the length of connecting part should be designed in consideration of construction tolerance because connecting member housing, adapter and cable are separate parts,

④ 케이블 아답터는 제조 및 시공 여건상 어느 정도의 두께를 유지하여야 하기 때문에 전체적으로 직선 접속재 하우징은 상당히 크게 설계되어야 하였다.④ Since the cable adapter has to maintain a certain thickness in manufacturing and construction conditions, the overall linear connector housing has to be designed considerably.

또한, 종래에는 이형 케이블 도체부를 서로 연결하는 이형 슬리브는 좌우가 관통된 파이프형으로 되어 있기 때문에 작은 직경의 케이블 도체를 기준으로 삼으면, 큰 직경의 케이블 도체는 작은 파이프 안에 조립 자체가 안되어 시공이 불가능하며, 이와 반대로 큰 직경의 케이블 도체를 기준으로 삼으면 작은 직경의 케이블 도체는 큰 파이프 안에 조립이 되나 직경 차이가 크게 형성되어 압축공정이 불가능함에 따라 접속불량을 일으킬 소지가 많았다.In addition, since the release sleeves connecting the release cable conductors to each other are generally pipe-shaped through left and right, the cable conductors of a small diameter are used as a reference, and the large diameter cable conductors are not assembled in a small pipe. On the contrary, if the cable conductor of large diameter is used as a reference, the cable conductor of small diameter is assembled in the large pipe, but the diameter difference is large, so that the compression process is impossible, and thus there is a possibility of poor connection.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 이중 케이블 직선 접속시 오접속에 따른 접속재 손상을 방지하고 시공이 용이할 뿐만 아니라, 마찰, 습기 등 외부의 여러 가지 환경적 오염 등에도 저항력을 갖추면서 전압누설이 방지되고, 반복되는 기계적 스트레스에 충분히 견딜 수 있는 개량된 이형 케이블 직선 접속재를 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the conventional problems as described above, and prevents damage to the connection material due to incorrect connection when connecting a double cable straight and easy to install, and various environmental pollutions such as friction, moisture, etc. It is also an object of the present invention to provide an improved release cable straight connection member that is resistant to voltage leakage and can withstand repeated mechanical stress.

상기와 같은 목적을 달성하기 위한 본 발명은 대직경 케이블과 소직경 케이블을 서로 직선으로 접속시키기 위해 러버재질의 몸체 하우징을 갖추고 접속 슬리브가 내장되어 이루어진 케이블 직선 접속재에 있어서, 상기 몸체 하우징 양쪽으로는 이형 직경을 갖는 케이블 입구들이 형성되고, 이형 케이블들의 접속 말단부들을 케이블 절연체로 감싸며, 직경이 다른 대직경 케이블과 소직경 케이블들이 접속 연결되는 이형 슬리브에는 상기 대, 소직경 케이블에 맞는 대, 소직경을 갖는 접속홈들이 양쪽으로 형성되어 있고, 상기 대, 소직경 케이블들의 중성선들은 이형 클램프에 의해 서로 연결되어 이루어진 구조로 되어 있다.In order to achieve the above object, the present invention provides a cable straight connection member having a rubber housing and a connection sleeve therein for connecting a large diameter cable and a small diameter cable to each other in a straight line. The cable inlets with the different diameters are formed, the connecting ends of the different cables are wrapped with a cable insulator, and the large sleeves with different diameters and the small diameter cables are connected to and connected to the large and small diameter cables. Connection grooves having two sides are formed, and the neutral wires of the large and small diameter cables are connected to each other by a release clamp.

이하, 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 이형 케이블 직선 접속재에 이형 케이블이 연결된 상태를 나타낸 단면도이고, 도 2는 본 발명에 따른 몸체 하우징의 외관도이다.1 is a cross-sectional view showing a state in which a release cable is connected to a release cable straight connection member according to the present invention, Figure 2 is an external view of the body housing according to the present invention.

In this case, cable inlets 5a and 5b having a release diameter are formed on both sides of the body housing 3, and the connection ends of the release cables 2a and 2b are wrapped with a cable insulator 6, and the diameters are different. The connection release sleeve 4 to which the large-diameter cable 2a and the small-diameter cable 2b are connected to each other is provided with a connection groove 7a having a corresponding diameter corresponding to the large, small-diameter cables 2a and 2b, and a small diameter. 7b) are formed on both sides, and the neutral wires 8a, 8b of the large-diameter cables 2a, 2b are connected to each other outside the body housing 3 by a release clamp 9.

여기서 상기 몸체 하우징(3)의 이형 케이블 입구(5a,5b)쪽 각각에는 도 2에 도시된 바와 같이 케이블 규격(예를 들어 직경이 600㎟와 325㎟)을 표기한 표시부(10)로 인하여 오접속 시공을 방지할 수 있도록 되어 있다.In this case, each of the release cable inlets 5a and 5b of the body housing 3 is misused due to the display unit 10 indicating a cable standard (for example, 600 mm 2 and 325 mm 2 in diameter) as shown in FIG. 2. The connection construction can be prevented.

또한 상기 접속 이형 슬리브(4)는 대, 소직경 케이블(2a,2b)들과 동등한 전기저항을 유지하는 재질로 되어 있음은 물론이며, 케이블 접속시 기계적 스트레스를 견디는 구조로 되어 있다.In addition, the connection release sleeve 4 is made of a material that maintains electrical resistance equivalent to that of the large and small diameter cables 2a and 2b, as well as a structure that withstands mechanical stress when connecting the cable.

상기와 같이 본 발명에 따른 이형 케이블 직선 접속재는 서로 다른 직경을 갖는 이형 케이블을 직선으로 접속할 때 오접속에 따른 접속재 손상을 방지하면서 시공성이 용이하게 이루어지는 잇점을 갖는다.As described above, the release cable linear connecting member according to the present invention has an advantage in that construction is easily performed while preventing the connection member damage caused by misconnection when connecting release cables having different diameters in a straight line.
