Description
본 고안은 전기공사에 많이 사용되는 부스바(bus bar)를 애자와 같은 지지체에 지지 및 고정하기 위해 사용하는 볼트의 머리부위의 노출을 막기 위해 그 부위에 설치하는 절연캡구조에 관한 것으로, 특히 볼트머리 수용부와 그 하단에 플랜지부와 이 플랜지부 내측으로 흡착부를 형성한 연질의 절연캡을 구비하여 간단히 볼트머리에 눌러 설치하도록 하는 부스바 체결용 볼트의 절연갭구조에 관한 것이다.The present invention relates to an insulating cap structure that is installed in the site to prevent the exposure of the head of the bolt used to support and fix the bus bar (bus bar), which is often used in electrical work to the support such as insulator An insulating gap structure of a busbar fastening bolt provided with a bolt head receiving portion and a soft insulating cap having a flange portion and a suction portion formed inside the flange portion at a lower end thereof is simply pressed on the bolt head.
일반적으로 전기공사에서 애자와 같은 지지체에 볼트로 부스바(bus bar)가 지지 및 고정되고 또한 노출되는 상기 볼트의 머리부위 가리기 위해 절연캡이 사용되어 왔다.In general, an insulating cap has been used to cover the head portion of the bolt in which the bus bar is supported, fixed and exposed to the support such as insulator in electrical work.
위와같이 사용되는 절연캡은 도 3에 도시된 바와같이 볼트(60')에 스프링와셔(20')와 탭와셔(30')가 순차적으로 삽입되고, 절연피복(44')으로 외부가 감싸진 부스바(40')에 형성된 체결공(42')과 애자(80')와 같은 지지체에 형성된 삽입공에 볼트(60')가 삽입되며, 이 볼트(60')에 다시 평와셔(50')가 삽입되어 너트(70')를 돌려 나선체결시킨후, 볼트머리수용부(12')와 하단내측에 암나사부(14')를 형성한 경질의 절연갭(10')을 상기 볼트(60')머리부에 돌려 상기 암나사부(14')와 탭와셔(30')의 수나사부(32')를 나선 결합시켜 구성된다.The insulating cap used as above is a spring washer 20 'and a tap washer 30' are sequentially inserted into the bolt 60 ', as shown in Figure 3, the outside is covered with an insulating coating 44' The bolt 60 'is inserted into the insertion hole formed in the support body such as the fastening hole 42' formed on the busbar 40 'and the insulator 80', and the flat washer 50 'is again inserted into the bolt 60'. ) Is inserted into the nut 70 'and screwed into place, and then the bolt 60 receives a rigid insulating gap 10' having a female head 14 'formed on the inner side of the bolt head receiving portion 12' and the lower end of the bolt 60 '. The female threaded portion 14 'and the male threaded portion 32' of the tap washer 30 'are spirally coupled to the head.
이와같이 구성되는 종래의 절연캡는 탭와셔의 사용으로 절연캡을 손으로 돌려서 설치되는 불편함이 발생되어 작업이 힘들어지며, 또한 일체로 사출 성형되는 절연캡 자체도 고가일뿐아니라 고단가의 탭와셔를 사용함으로써 공사 비용도 증가되는 문제점이 있었다.Conventional insulation caps constructed as described above are inconvenient to be installed by turning the insulation cap by hand using the tap washer, which makes the work difficult, and the insulation cap itself, which is integrally injection-molded, is not only expensive but also uses a high-priced tap washer. By doing so, there was a problem that the construction cost also increased.
본 고안은 상기와 같은 문제점을 감안하여 안출한 것이며, 그 목적은 외부에 노출된 볼트머리에 간단히 눌러서 설치하여 작업이 수월하며, 또한 저비용의 부품을 사용하여 작업 비용까지도 절감 할수 있도록 하는 연질의 부스바 체결용 볼트의 절연캡구조를 제공하는데 있다.The present invention has been devised in view of the above problems, and its purpose is to install by simply pressing the bolt head exposed to the outside, so that the work is easy, and the booth is soft so that the operation cost can be reduced by using low-cost parts. An insulating cap structure of a bar fastening bolt is provided.
