Description

열융착 연결구{Fusion coupler}Thermal Fusion Splicer {Fusion coupler}

본 발명은 열융착 연결구에 관한 것으로서, 더욱 상세하게는 다양한 사이즈의 연결구를 보다 간편하게 제작할 수 있어 그 생산성이 향상되며, 이에 따른 제작단가를 낮출 수 있도록 된 열융착 연결구에 관한 것이다.The present invention relates to a heat-sealed connector, and more particularly to a heat-sealed connector that can be produced more easily to the connector of a variety of sizes to improve its productivity, thereby lowering the manufacturing cost.

일반적으로 열융착 연결구는 그 양측에 한 쌍의 파이프를 끼움 결합하여 결합된 파이프를 열융착하여 연결하는 것으로서, 도 1과 도 2는 종래의 열융착 연결구의 단면도이다. 이를 참조하면, 주벽면에 한 쌍의 단자삽입공(33)과 관찰공(35)이 관통 형성된 외관체(30) 내부 양측에 한 쌍의 융착링(20)을 일체로 인서트 사출하여 제조된다. 이때, 상기 융착링(20)은 그 두께가 얇은 관체의 외주면에 전열선(21)이 나선형으로 감겨지며 이 전열선(21) 양단에는 한 쌍의 접속단자(23)가 마련되어 외관체의 단자삽입공(33)을 통해 일정길이 외부로 돌출되도록 설치된다.In general, the heat-sealing connector is a heat-sealed connection of a pipe coupled by fitting a pair of pipes on both sides thereof, Figure 1 and Figure 2 is a cross-sectional view of a conventional heat-sealing connector. Referring to this, a pair of fusion ring 20 is integrally inserted into both sides of the exterior body 30 through which a pair of terminal insertion holes 33 and observation holes 35 are formed on the main wall, and are manufactured by insert injection. At this time, the fusion ring 20 has a heating wire 21 is wound spirally on the outer circumferential surface of the thin tube, the pair of connecting terminals 23 are provided at both ends of the heating wire 21 terminal insertion hole ( 33) is installed to protrude a certain length outside.

따라서, 상기 열융착 연결구는 그 양측에 한 쌍의 파이프(3)를 끼움 결합하고 전열선(21)에 전원을 공급하면 융착링(20)이 가열 용융되면서 양측 파이프(3)가 연결구 내에 밀폐되도록 융착되며, 동시에 그 용융액이 관찰공(35)을 통해 외부로 흘러나오게 되므로 이를 통해 융착 여부를 외부에서 쉽게 확인할 수 있다.Therefore, the heat fusion splicing is fused so that both pipes 3 are sealed in the connector while the fusion ring 20 is heated and melted by fitting a pair of pipes 3 on both sides thereof and supplying power to the heating wire 21. At the same time, since the melt flows to the outside through the observation hole 35, it can be easily confirmed from the outside through the fusion.

그러나, 이러한 연결구는 융착링(20)을 외관체(30) 내부에 인서트 사출하기 위한 금형이 필요하며 더욱이 상기 연결구의 사이즈가 커지게 되면 이를 제조하는 금형과 주변장치의 사이즈도 함께 커져야 하므로 이에 따른 설비투자의 비용이 증가된다는 문제점이 있다.However, such a connector requires a mold for insert-injecting the fusion ring 20 into the exterior body 30. Moreover, when the size of the connector increases, the mold and the peripheral apparatuses for manufacturing the connector have to be increased together. There is a problem that the cost of equipment investment increases.

또한, 이러한 연결구는 연결될 파이프(3)의 사이즈에 따라 각기 다른 사이즈로 제작되어야 하며, 각 사이즈별로 고가의 금형이 각각 별도로 구비되어야 하기 때문에 그 설비투자의 비용이 더욱 증가되는 문제점이 있다.In addition, these connectors must be manufactured in different sizes according to the size of the pipe (3) to be connected, there is a problem that the cost of the equipment investment is further increased because expensive molds must be provided separately for each size.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 다양한 사이즈의 관체 내부에 별체로 된 융착링을 끼움 결합하여 제조되므로, 인서트 사출용 금형을 각 사이즈별로 구비하지 않아도 되며, 이에 따른 설비투자가 현저히 줄어드는 열융착 연결구를 제공하는 것이다.The present invention is to solve the above problems, the object of the present invention is manufactured by fitting a separate fusion ring inside the tube of various sizes, it is not necessary to provide a mold for insert injection for each size, accordingly It is to provide a heat-sealed connector that significantly reduces equipment investment.

본 발명에 따르면, 한 쌍의 파이프(3)를 서로 밀폐되도록 연결하는 열융착 연결구에 있어서, 파이프를 소정길이로 절단하여 얻어진 관체(5)의 주벽에 단자삽입공(13)을 관통 형성한 외관체(10)와, 이 외관체(10)와는 별체로 제작되고 그 외주면에는 전열선(21)이 감겨져 형성되며 상기 외관체(10)의 내부 양측에 결합되는 열가소성수지재로 된 한 쌍의 융착링(20)과, 상기 전열선(21)의 양단에 구비되어 외관체(10)의 단자삽입공(13)을 통해 외부로 돌출되는 접속단자(23)를 포함하여 구성된 것을 특징으로 하는 열융착 연결구가 제공된다.According to the present invention, in the heat-sealing connector for connecting the pair of pipes 3 to be sealed to each other, the external appearance of the terminal insertion hole 13 through the main wall of the tubular body 5 obtained by cutting the pipe to a predetermined length A pair of fusion splicing rings made of a sieve 10 and a thermoplastic resin material which is manufactured separately from the exterior body 10 and is formed by winding heating wires 21 on the outer circumferential surface thereof and bonded to both inner sides of the exterior body 10. (20) and the heat-sealing connector is provided on both ends of the heating wire (21) comprising a connection terminal 23 protruding to the outside through the terminal insertion hole 13 of the exterior body (10) Is provided.

이하, 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 3은 본 발명에 따른 열융착 연결구의 사시도이고, 도 4a~4d는 본 발명에 따른 열융착 연결구의 제조공정을 도시한 공정도이다. 이를 참조하면, 상기 외관체(10)는 서로 연결될 파이프(3)보다 다소 작은 내경의 관체(파이프)(5)를 소정 길이로 절단하여 한 쌍의 융착링(20)이 양측으로부터 끼워질 수 있도록 그 내경을 양측단으로부터 소정깊이 확장 가공하여 제조된다. 또, 상기 외관체(10)의 주벽면 양측에는 한쌍의 단자삽입공(13)을 관통 형성하여 융착링(20) 외주면에 감겨진 전열선(21) 양단부의 접속단자(23)가 외부로 돌출되도록 설치되며, 주벽면 소정위치에는 내부의 융착링(20)까지 관통된 관찰공(15)이 형성된다.3 is a perspective view of a heat-sealed connector according to the present invention, Figures 4a to 4d is a process diagram showing a manufacturing process of the heat-sealed connector according to the invention. Referring to this, the exterior body 10 cuts a pipe (pipe) 5 having a smaller diameter than a pipe 3 to be connected to each other to a predetermined length so that a pair of fusion rings 20 can be fitted from both sides. The inner diameter is manufactured by expanding a predetermined depth from both ends. In addition, a pair of terminal insertion holes 13 are formed in both sides of the main wall surface of the exterior body 10 so that the connection terminals 23 at both ends of the heating wire 21 wound on the outer circumferential surface of the fusion ring 20 protrude outward. The observation hole 15 penetrated to the fusion ring 20 therein is formed at a predetermined position on the main wall surface.

따라서, 상기 외관체(10)는 상당한 길이의 기성화된 관체를 소정 길이로 절단하여 절단된 관체(5)의 주벽면 양측에 각기 한 쌍의 단자삽입공(13)과 관찰공(15)을 관통 형성하고, 이 관체(5)의 내경을 양측으로부터 소정깊이 확장 가공하여 한 쌍의 융착링(20)이 삽입 설치되도록 하므로써 제조된다. 또, 상기 외관체(10)의 단자삽입공(13)에 전열선 양단의 접속단자(23)를 끼워 외부로 돌출되도록 설치하고, 외관체(10)의 내부 양측에 융착링(20)을 끼움 결합하여 연결구(1)를 완성한다. 한편, 이러한 외관체는 하나의 단품으로 사출성형 될 수도 있다.Accordingly, the exterior body 10 penetrates through a pair of terminal insertion holes 13 and observation holes 15 on both sides of the main wall surface of the tubular body 5 cut by cutting a ready-made tubular body of considerable length into a predetermined length. The inner diameter of the tubular body 5 is formed by expanding a predetermined depth from both sides so that a pair of fusion splicing rings 20 can be inserted. In addition, the connection terminal 23 of both ends of the heating wire is inserted into the terminal insertion hole 13 of the exterior body 10 so as to protrude to the outside, and the fusion ring 20 is fitted to both inner sides of the exterior body 10. To complete the connector (1). On the other hand, such an exterior body may be injection molded in one piece.

이어서, 상기 연결구(1)의 양측에 한 쌍의 파이프(3)를 끼움 결합하고 전열선(21)에 전원을 공급하여 융착링(20)이 가열 용융되도록 하면, 양측으로부터 끼워진 파이프(3)가 연결구(1)에 밀폐되도록 융착 결합됨과 동시에 그 용융액이 관찰공(15)을 통해 외부로 흘러나오게 되므로 이를 통해 융착여부를 외부에서 쉽게 확인할 수 있게 된다.Subsequently, when a pair of pipes 3 are fitted to both sides of the connector 1 and power is supplied to the heating wire 21 so that the fusion ring 20 is heated and melted, the pipe 3 fitted from both sides is connected to the connector. At the same time as the fusion bonding to be sealed to (1), the melt is flowed out through the observation hole 15, it can be easily confirmed from the outside through this.

이상에서와 같은 본 발명에 의하면, 다양한 사이즈의 연결구(10)내부에 별체로 된 융착링(20)을 끼움 결합하여 열융착 연결구(1)를 완성하므로, 사이즈별로 각기 다른 인서트 사출용 금형을 별도로 구비하지 않아도 되므로 이에 따른 제조 설비와 투자비용을 현저히 줄일 수 있다.According to the present invention as described above, by inserting a separate fusion ring 20 into the connector 10 of various sizes to complete the heat-sealed connector (1), different insert injection molds for each size separately Since it does not have to be provided, the manufacturing equipment and investment costs can be significantly reduced.
