본 고안은 지하에 매설되는 지중전선관의 연결을 위해 사용되는 연결구에 관한 것으로 특히, 방수성이 뛰어나고 조립이 간편한 지중전선관용 방수엽결장치에 관한 것이다.The present invention relates to a connector used for connecting underground cable pipes buried underground, and more particularly, to waterproof waterproofing device for underground cable pipes excellent waterproof and easy to assemble.
종래에 사용되고 있는 연결장치는 연결하고자 하는 전선관의 외경보다 큰 내경을 갖는 나선연결관을 이용하여 지중전선관의 일측에 완전히 나사결합한 후, 다른 전선관을 맞대어 놓고, 나선연결관을 반대방향으로 회전시켜 나선연결관이 두 지중전선관의 중앙에 위치하도록 한다음, 나선연결관의 양끝을 방수테이프로 감아서 고정하는 방식으로 연결하였었다.Conventionally used connection device is screwed completely to one side of the underground conduit using a spiral connector having an inner diameter larger than the outer diameter of the conduit to be connected, and then face the other conduit, and rotate the spiral connector in the opposite direction The connectors were placed in the center of the two underground conduits, and then both ends of the spiral connectors were wound and secured by waterproof tape.
그러나 이와같은 연결방식은 소폭으로 파여진 매립공간에서 작업자가 직접 들어가 나선연결관의 양끝을 방수테이프로 감아주어야 하는 것이어서, 연결작업이 불편하고, 테이프를 감아주는 상태가 부실하게 되어 완전한 방수상태를 얻을 수 없었으며, 시공단가의 상승과 더불어 작업시간이 길어지게 되는등의 문제점이 있었다.However, this type of connection requires a worker to directly enter the burial space, which is narrowly dug, to wind both ends of the spiral connection pipe with a waterproof tape. There was a problem such as increase in construction cost and longer working time.
또한, 방수테이프를 이용하여 완벽하게 연결구의 양끝을 막아놓았다 할지라도, 시간이 흐름에 따라 지압(地壓)에 의한 연결부의 변형으로 접착부가 탈락되어 전선관 내부로 물이 스며들어 합선이나 단선의 원인이 되는 것이었다.In addition, even if both ends of the connector are completely covered with waterproof tape, the adhesive part is dropped due to the deformation of the connection part due to the pressure over time, causing water to penetrate into the conduit and cause short circuit or disconnection. It was to be.
이와같은 문제점을 해결하기 위하여 지중전선관의 관말구에 방수캡을 끼우고, 체결밴드로 간단하게 고정할수 있도록 된 선고안(본인의 실용신안등록출원 제92-13,189호)과, 이를 개량한 본인의 개량된 후고안(실용신안들록출원 제93-8,090호)이 제안되어 있다.In order to solve this problem, a water proof cap is inserted in the end of the underground conduit tube, and the declaration can be easily fixed with a fastening band (our Utility Model Application No. 92-13,189), and the improved person An improved fugoan (Utility Model Application No. 93-8,090) has been proposed.
상기 선고안은 나선형 지중전선관의 외경나사부와 나합되는 내경나사부가 형성된 연질의 합성수지 또는 합성고무로 된 탄성을 가진 방수캡을 형성한 후, 이 방수캡을 연결하고자 하는 두 지중전선관의 관말구에 나착하여 두 방수캡의 선단이 서로 대향되게 밀착시키고, 양측 방수캡의 외주면을 체결구가 형성된 박판상의 합성수지제체결밴드로 긴밀하게 위포하여 양측 전선관이 연결되도록 된 것으로, 방수캡을 이용하여 두 지중전선관을 간편하게 연결할 수는 있으나, 압출성형되는 지중전선관의 외경나사부를 이루는 나선부의 굴곡이 일정하게 절곡되지 못하여 방수캡으로 관말구를 완벽하게 차단할 수 없었던 문제점이 있었다.The draft is formed of a soft synthetic resin or elastic rubber cap formed of an inner diameter screw portion that is screwed with the outer diameter screw portion of the spiral underground conduit tube, and then attached to the tube ends of the two underground conduits to which the waterproof cap is to be connected. The front ends of the two waterproof caps are in close contact with each other, and the outer circumferential surfaces of the two waterproof caps are closely overlapped with a thin synthetic resin fastening band in which fasteners are formed so that both conduits can be connected. Although it can be easily connected, the bending of the spiral portion forming the outer diameter screw portion of the underground wire tube to be extruded could not be bent constantly, there was a problem that could not completely block the end of the tube with a waterproof cap.
이를 개량한 후 고안은,After improving it, devise
선단이 확개되어 밀착프랜지를 형성한 방수캡에, 연질의 합성수지 또는 합성고무로 된 탄성을 가진 패킹을 삽입한 다음, 지중전선관에 나사조립하여 전선관의 관말구가 상기 패킹에 긴밀하게 밀착되도록 조립하고, 체결밴드로서 양측의 방수캡을 체결하여 고정하도록 된 것으로 지중전선관의 관말구에 긴밀하게 밀착고정된 패킹에 의하여 방수연결 되도록 하고자 하였으나, 실험결과 관말구가 균일하게 절단되지 않으면 패킹과 관말구의 밀착상태가 부분별로 차이가 생기고, 지중전선관과 방수캡에 과도한 압력이 가해질때, 전선관과 패킹사이에 밀착상태가 긴밀하지 않은 부분에 미세한 간격이 발생하고, 이 간격으로 물이 스며들게 되는 문제점이 발생함을 알 수 있었다.Insert the packing with elasticity made of soft synthetic resin or synthetic rubber into the waterproof cap with the tip extended to form a close flange, and then screw the assembly into the underground cable to assemble the tube end of the cable tightly to the packing. As a fastening band, the waterproof caps of both sides were fastened to fix the packing by tight packing tightly fixed to the end of the underground cable. However, if the end of the pipe is not cut uniformly, the packing and the end of the pipe When there is a difference in the adhesion state by part and when excessive pressure is applied to the underground conduit pipe and the waterproof cap, there is a problem that a minute gap occurs between the intimate contact state between the conduit pipe and the packing, and water penetrates at this interval. I could see.
본 고안은 이와같이 지중전선관의 관말구와 패킹사이에 미세한 간격이 발생치 않도록 하기위하여 연결하고자 하는 지중전선관의 관말구를 균일하게 절단할 수 있도록 함과 동시에, 균일하게 절단된 절단면에 패킹을 밀착시키되, 보울트와 너트를 이용하여 강제로 밀착시킴으로써 완전한 방수연결효과를 얻을 수 있도록 구성한 것으로 이하, 첨부도면에 의하여 상세히 설명한다.The present invention allows the tube ends of the underground wire tubes to be connected to be uniformly cut in order to prevent the minute spacing between the tube ends and the packings of the underground wire tubes, and to close the packing to the uniformly cut surface. , It is configured to obtain a complete waterproof connection effect by forcibly close by using a bolt and a nut, which will be described in detail with reference to the accompanying drawings.
