본 고안은 FBT케이스와 저압보빈에서 코아를 끼워 삽입하는 저부에 있어서 이를 상호결합하기 위한 구조에 관한 것으로서, 이는 특히, 상기 결합부위의 케이스에 각각 기밀턱과 경사면을 형성시킨 FBT케이스와 저압보빈과의 코아안내부 결합구조에 관한 것이다.The present invention relates to a structure for mutual coupling in the bottom of the core to insert the core in the FBT case and the low-pressure bobbin, in particular, the FBT case and the low-pressure bobbin and the airtight jaw and the inclined surface respectively formed in the case of the coupling portion; It relates to the core guide coupling structure of the.

일반적으로 FBT케이스와 저압보빈의 결합구조는 상기 저압보빈의 중앙부위로 코아가 진입되어 외부로서 현출고정되는 상기 코아의 삽입부를 상기 FBT케이스내부에 결합토록함과 동시에 에폭시 수지 충전시동을 고려하여 기밀유지용 가이드편 및 가이드홈을 마련하여서 된다.In general, the coupling structure between the FBT case and the low pressure bobbin allows the core to be inserted into the central portion of the low pressure bobbin so as to couple the insertion portion of the core to the inside of the FBT case while keeping the airtight in consideration of the epoxy resin filling start. Guide pieces and guide grooves are to be provided.

이러한 구조에 있어서 종래에는 제1도 및 제2도에 도시한 바와같이, FBT케이스(1)와 저압보빈(2)의 코아가 삽입되는 연결부를 개구시키지 아니하고, 각기 연결편(11)(21)을 일체로 성형제작하여 상기 FBT케이스(1)내에 저압보빈(2)을 삽입고정시켜 에폭시 수지등을 충진하는 것이었다.In this structure, as shown in FIGS. 1 and 2, the connecting pieces 11 and 21 are not opened, respectively, as shown in FIGS. 1 and 2 without opening the connection portion into which the cores of the FBT case 1 and the low pressure bobbin 2 are inserted. It was molded integrally, and the low pressure bobbin 2 was inserted into the FBT case 1 to fix the epoxy resin.

그러나, 이러한 종래의 FBT케이스와 서압보빈의 결합구조는, 상기 FBT케이스(1)와 저압보빈(2)에 연결된 연결편(11)(21)에 의해 절연수지물의 누설은 방지할 수 있으나, 절연수지물의 경화후 코아가 삽입되는 연결편(11)(21)을 펀칭(punching)작업에 의해 절단하여야 되는 문제점이 있었다.However, such a conventional coupling structure of the FBT case and the low pressure bobbin, although the insulating resin can be prevented from leaking by the connecting pieces 11 and 21 connected to the FBT case 1 and the low pressure bobbin 2. After hardening the water, there was a problem in that the connecting pieces 11 and 21 into which the core is inserted are cut by a punching operation.

또한, 홈을 내어 절단할때 연결편(11)(21)주위의 사출물까지 절단충격에 의해 떨어지는 경우가 빈번하게 발생하여 외관이 매우 흉하게 보이는등 많은 문제점이 있었던 것이다. 따라서, 종래에는 작업동정의 수가 많아질뿐만 아니라 자재손실등으로 인해 생산률이 저하되는등의 문제점이 있었다.In addition, there are many problems, such as the appearance of the appearance is very unpleasant as the case of frequent dropping to the injection molding around the connecting piece (11) (21) when cutting out the groove. Therefore, in the related art, not only the number of work identification increases but also the production rate decreases due to material loss.

본 고안은 상기한 바와같은 종래의 문제점들을 개선하기 위하여 안출된 것으로서 그 목적은, 저압보빈에 설치된 가이드레일의 형상을 ""형으로 형성하고, 이와대향되어 접촉하는 FBT케이스의 가이드돌기를 "T"형상으로 형성하며, 상기 가이드돌기의 내측으로 양측에 가이드경사면을 마련함으로써, 가이드레일과 가이드돌기의 긴밀한 결합에 의해 충전물인 에폭시수지의 외부누출을 유효하게 방지시킴은 물론, 상호 결합작업을 능률적으로 수행할 수 있는 FBT케이스와 저압보빈과의 코아안내부 결합구조를 제공하는데 있다.The present invention has been made in order to solve the above-mentioned problems as described above, and its purpose is to change the shape of the guide rail installed in the low pressure bobbin. Formed in the shape of ", and the guide projections of the FBT case facing and contacted with the " T " shape, and by providing guide inclined surfaces on both sides inward of the guide projections, are closely packed with the guide rail and the guide projections In addition to effectively preventing the external leakage of the phosphorous epoxy resin, it is to provide a core guide coupling structure between the FBT case and the low-pressure bobbin that can efficiently perform the mutual coupling operation.

이하, 첨부된 도면에 의거하여 본 고안을 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

즉, 제3도 및 제4도에 도시한 바와같이, 저압보빈(2)의 가이드레일(22)을 ""형상으로 형성하고, 이에 대향되어 면접촉하여 결합되는 FBT케이스(1)의 가이드돌기(12)(13)를 "T"형상으로 하며, 상기 가이드돌기(13)내측으로 양측에 가이드경사면(14)을 마련한 구성으로 이루어진다.That is, as shown in Figs. 3 and 4, the guide rail 22 of the low pressure bobbin 2 is " &Quot; T " shape of the guide protrusions 12 and 13 of the FBT case 1, which are formed in a shape and are opposed to and face-contacted to each other, and have guide inclined surfaces 14 on both sides inward of the guide protrusion 13. ) Is made up of the configuration.

이와같이 구성된 본 고안은, FBT케이스(1)내에 저압보빈(2)이 결합하여 고정되는 상태에서 상기 FBT케이스(1)의 가이드돌기(12)(13)가 "T"형상으로 되고, 내측으로 양측에 경사면(14)이 마련되어 저압보빈(2)의 ""형상의 가이드레일(22)과 각각 면접촉을 하면서 긴밀하게 압입결합되므로 충전물인 에폭시수지의 외부누출을 유효하게 방지시키고, 상기 결합작업을 능률적으로 수행할 수가 있는 것이다.According to the present invention configured as described above, the guide protrusions 12 and 13 of the FBT case 1 are in a "T" shape in a state where the low pressure bobbin 2 is coupled and fixed in the FBT case 1, and both sides inward. The inclined surface 14 on the low pressure bobbin 2 " "In close contact with each of the shape of the guide rails 22, they are intimately press-fitted, thereby effectively preventing external leakage of the epoxy resin as a filler and efficiently performing the joining operation.

상술한 바와 같이 본 고안에 따른 FBT케이스와 저압보빈과의 코아안내부 결합구조에 의하면, 저압보빈의 가이드레일과 FBT케이스의 가이드돌기구조를 상기와 같이 개선함으로써, 가이드레일과 가이드돌기의 긴밀한 결합에 의해 충전물인 에폭시수지의 외부누출을 유효하게 방지하며, 상기 결합작업을 능률적으로 수행할 수 있는 잇점이 있는 것이다.As described above, according to the coupling structure of the core guide portion between the FBT case and the low pressure bobbin according to the present invention, the guide rail of the low pressure bobbin and the guide protrusion structure of the FBT case are improved as described above, thereby closely coupling the guide rail and the guide protrusion. By effectively preventing the external leakage of the epoxy resin as a filler, there is an advantage that can efficiently perform the bonding operation.
