저압케이블 접속장치와 저압케이블의 접속을 위한 접속슬리브{A circle-fixity sleeve for low-voltage}Connection sleeve for connecting low voltage cable connection device and low voltage cable {A circle-fixity sleeve for low-voltage}

본 고안은 맨홀 또는 핸드홀내에 저압케이블의 분기 또는 고객 인입접속점에 사용되는 저압케이블 접속장치에 저압케이블을 접속하기 위한 접속슬리브에 관한것으로, 더 상세하게는 접속슬리브의 볼트고정홈부를 외주면이 원형을 이루는 환봉형상의 접속홈으로 개선하여 어느 방향에서든 조임볼트의 안전한 면접촉이 이루어지도록 함으로서 보다 안전하고 확실한 결속력을 유지할 수 있는 저압케이블 접속장치와 저압케이블의 접속을 위한 접속슬리브에 관한 것이다.The present invention relates to a connecting sleeve for connecting a low voltage cable to a low voltage cable connecting device used for branching of a low pressure cable or a customer inlet connection point in a manhole or a hand hole, and more specifically, a circular outer peripheral surface of the bolt fixing groove of the connection sleeve is circular. The present invention relates to a low-voltage cable connecting device capable of maintaining a safer and more secure binding force and a connecting sleeve for connecting a low-voltage cable by improving a round bar-shaped connecting groove to achieve safe surface contact of the tightening bolt in any direction.

통상의 저압케이블 접속장치는, 좁은 공간의 맨홀 또는 핸드홀내에서 3회선 이상의 저압케이블을 분기할 때 사용하는 것으로, 전기공급방식에 따라 3상 4선식과 단상 3선식이 있으며, 지중 저압분기장치를 각각의 상별로 구분하여 시설함으로써 회선구분이 간결하고 설치방법을 간단하게 한다는 것은 이미 주지된 바와 같다. 이와 같은 종래 저압케이블 접속장치(60)는 맨홀벽면에 앵커볼트로 고정된 지지대에 접속장치를 안착,고정시키고 저압케이블(50)을 접속길이에 맞춰 절단한 후 끝부분의 외피를 박피하고 이 노출된 도체(52)부분을 접속슬리브(100)에 끼워 그 외면을 압축기로 압축,고정시킨다. 그후 저압케이블의 도체부분에 취부된 접속슬리브에 의해서 본체의 접속탭(64)에 끼우고 이와 수직향으로 끼워지는 조임볼트(62)를 L형렌치를 사용하여 접속슬리브를 조임,고정시킨다. 이때 접속슬리브의 선단에는 외면둘레에 다면을 이루는 볼트고정홈부(120)가 형성되어 있어 나사조립되는 고정볼트의 끝단이 이 볼트고정홈부에 면접촉하는 조임방식으로 접속슬리브를 고정시키고 있다.Conventional low voltage cable connection devices are used to branch low voltage cables of three or more lines in a narrow manhole or handhole. There are three-phase four-wire and single-phase three-wire systems depending on the electricity supply method. It is well known that the line classification is simplified and the installation method is simplified by providing facilities separately for each phase. The conventional low pressure cable connection device 60 is seated and secured to the support fixed to the anchor bolt on the manhole wall surface and cut the low pressure cable 50 to the connection length and then peeled off the outer skin of the end and exposed The conductor 52 is inserted into the connecting sleeve 100, and the outer surface thereof is compressed and fixed by a compressor. Thereafter, the connecting sleeve is fitted to the connecting tab 64 of the main body by a connecting sleeve attached to the conductor portion of the low-voltage cable, and the connecting bolt 62 is vertically tightened to fix and tighten the connecting sleeve using an L-shaped wrench. At this time, the front end of the connection sleeve is formed with a bolt fixing groove 120 which forms a multi-faced outer periphery, so that the end of the fixing bolt to be screwed to the connection sleeve is fixed by the tightening method in surface contact with the bolt fixing groove.

그러나 접속슬리브의 볼트고정홈부는 그 외면이 다면(多面)을 이루고 있어 조임볼트와 면접촉을 이루기 위해서는 조임방향이 한정되기 때문에 조임볼트가 정확하게 면접촉하지 못하고 볼트고정홈부의 모서리에 접촉하게 될 경우가 있게 된다. 따라서 작업자는 접속슬리브의 볼트고정홈부에 조임볼트가 정확히 면접촉하여 안전한 조임상태를 이루었는지를 육안으로 식별하여야 하는데 조임부분이 밀봉되어 있기 때문에 조임상태를 확인할 수 가 없어 시공에 어려움을 겪고 있다. 특히 볼트고정홈부의 면접촉부위를 벗어나 다른 방향의 각도에서 조임볼트가 모서리부분에 불완전하게 조임되었을 경우에는 안전한 결속력을 기대하기 어려울 뿐더러 볼트이완시에는 접속슬리브의 이탈로 인한 이상전압발생과 정전사고를 유발하게 되는 문제점이 있다.However, the bolt fixing groove of the connecting sleeve has a multifaceted outer surface, and the tightening direction is limited in order to make a surface contact with the tightening bolt. Will be. Therefore, the operator should visually identify whether the bolts in the bolt fixing grooves of the connection sleeve are in accurate contact with the surface and achieve a secure tightening state. However, since the tightening part is sealed, the tightening state cannot be confirmed, and thus, the construction is difficult. In particular, when the bolts are incompletely tightened to the corners at different angles away from the surface contact of the bolt fixing groove, it is difficult to expect a safe binding force.In addition, when the bolt is loosened, abnormal voltages and blackouts are caused by the disconnection of the connection sleeve. There is a problem that causes.

본 고안은 이러한 문제점을 해결하기 위하여 접속슬리브의 볼트고정홈부를 개선하여 외주면이 원형을 이루는 환봉형상의 접속홈으로 구성하여 접속슬리브가 어느 방향으로 위치하든지 상관없이 조임볼트에 의해 항상 정확하고 균일한 면접촉이 이루어지도록 함으로서 보다 확실하고 안전한 접속력을 유지할 수 있고, 또한 접속슬리브의 이탈로 인한 이상전압발생과 고장으로 인한 정전사고를 미연에 방지할 수 있도록 하는데 기술적 과제를 두고 있다.In order to solve this problem, the present invention improves the bolt fixing groove part of the connecting sleeve and consists of a round bar-shaped connecting groove whose outer circumferential surface is circular, so that it is always accurate and uniform by the fastening bolt regardless of which direction the connecting sleeve is located. By making the surface contact, more reliable and safe connection force can be maintained, and the technical problem is to prevent the occurrence of abnormal voltage and failure due to breakdown of the connection sleeve in advance.

본 고안은 접속슬리브 몸체(100)가 어떤방향으로 위치하든지 수직향으로 나사조립되는 조임볼트(62)는 항상 환봉형상의 접속홈(12)의 외면에 균일하게 면접촉을 이룸으로서 견고하고 안전한 결속력이 보장된다. 따라서 상호간의 접속력이 견고히 유지되어 전기적인 불완전 접촉이나 흔들림으로 인하여 접속장치로부터 접속슬리브 몸체(10)가 탈락될 염려가 없다. 따라서 본 고안은 접속불량 및 이탈로 인한 이상전압 발생과, 고장으로 인한 정전사고를 미연에 방지할 수 있음은 물론, 이와 같은 이상전압발생과 정전사고로 인해 소요되는 유지보수비용을 절감하여 경제적인 효과를 얻을 수 있을 뿐만 아니라 접속장치(60)내에서 접속슬리브에 조임볼트(62)가 양호한 조임을 이루었는지 육안으로 확인할 필요가 없어 작업시공이 용이하고 신속히 수행된다. 특히 본 고안은 접속슬리브를 성형가공하여 제조할 경우에도 가공이 용이하여 생산성을 증대시킬 수 있다.According to the present invention, the connecting bolt body 100 is assembled in the vertical direction regardless of the direction in which the connecting sleeve body 100 is located, and the bolts 62 are always in uniform surface contact with the outer surface of the annular connecting groove 12, thereby providing a firm and secure binding force. This is guaranteed. Therefore, there is no fear that the connection sleeve body 10 may be dropped from the connection device due to the incomplete contact or shaking of the electric connection between the two. Therefore, the present invention can prevent the occurrence of abnormal voltage due to poor connection and disconnection and the power failure due to the failure, as well as reduce the maintenance cost caused by the abnormal voltage occurrence and power failure. Not only can the effect be obtained, but it is not necessary to visually check whether the tightening bolt 62 has a good tightening in the connecting sleeve in the connecting device 60, and thus the work construction is easily and quickly performed. In particular, the present invention is easy to process even when manufactured by molding the connecting sleeve can increase the productivity.
