Description

열융착 관연결구 {Fusion coupler}Thermal Fusion Pipe Joints {Fusion coupler}

본 고안은 열융착 관연결구에 관한 것으로서, 보다 상세하게는 연결구의 열융착시 전열선이 숏트되지 않고 품질이 우수한 열융착 관연결구에 관한 것이다.The present invention relates to a heat fusion tube connector, and more particularly, to a heat fusion tube connector having excellent quality without shorting the heating wire during the heat fusion of the connector.

일반적으로 퓨전방식의 열융착 관연결구는 그 양측에 한 쌍의 파이프를 끼움 결합하여 결합된 파이프를 열융착하여 연결하는 것으로서, 도 1은 종래의 열융착 관연결구의 단면도이다. 이를 참조하면, 상기 열융착 관연결구는 주벽면에 한 쌍의 단자삽입공(14)과 관찰공(12)이 관통 형성된 연결관(3)과, 내면에 전열선(20)이 감겨져 상기 연결관(3) 내부 양측에 인써트 사출하여 결합된 한 쌍의 융착링(20)으로 이루어진다. 또, 상기 융착링(20)에 감겨진 전열선(2) 양단에는 연결관(3)의 단자삽입공(16)을 통해 외부로 돌출되는 접속단자(14)가 마련된다. 따라서, 연결관(3) 양측에 한 쌍의 파이프(10)를 끼움 결합하고 전열선(2)에 전원을 공급하여 약 300℃에서 300초간 가열하여 연결관(3)의 내경과 파이프(10)의 외경이 용융되어 융착 접합되도록 한다.In general, a fusion type heat fusion tube connector is a pair of pipes fitted on both sides thereof to heat-bond the combined pipes, and FIG. 1 is a cross-sectional view of a conventional heat fusion tube connector. Referring to this, the heat-sealing tube connector is a connector (3) formed through a pair of terminal insertion hole 14 and the observation hole 12 on the main wall surface, the heating wire 20 is wound around the inner tube ( 3) It consists of a pair of fusion ring (20) coupled by insert injection into both sides inside. In addition, both ends of the heating wire (2) wound around the fusion ring 20 is provided with a connection terminal 14 protruding to the outside through the terminal insertion hole 16 of the connection pipe (3). Accordingly, the pair of pipes 10 are fitted to both sides of the connection pipe 3, and the power is supplied to the heating wire 2 to be heated at about 300 ° C. for 300 seconds to provide an inner diameter of the connection pipe 3 and the pipe 10. The outer diameter is melted to allow fusion splicing.

그런데, 이러한 종래의 열융착 관연결구에 사용되는 전열선(2)은 융착링(20)과 동일한 열가소성 합성수지재로 코팅(5)이 이루어져 있어 열융착시 200℃ 전후의 온도에 도달하면서 전열선(2)에 코팅(5)된 수지가 용융되면서 전열선(2)의 선이 서로 접촉되어 숏트가 발생되는 문제점이 있었다. 또한, 전열선(2)이 숏트되면서 부분적으로 과열현상이 생기거나 열이 발생되지 않게 되므로 융착링(20)이 효과적으로 가열 용융되지 못하여 불량품이 발생되는 문제점이 있었다.By the way, the heating wire (2) used in the conventional heat-sealing tube connector is made of the same coating material (5) with the same thermoplastic synthetic resin as the fusion ring 20, the heat-transfer wire (2) while reaching the temperature around 200 ℃ during heat welding As the resin coated on 5 was melted, the wires of the heating wire 2 were in contact with each other, causing a short. In addition, since the heating wire 2 is shorted, the overheating phenomenon is not generated or heat is partially generated, and thus the fusion ring 20 is not effectively heated and melted, thereby causing a problem of defective products.

본 고안은 전술한 바와 같은 문제점을 해결하기 위한 것으로서, 본 고안의 목적은 연결구의 열융착시 전열선이 숏트되지 않고 품질이 우수한 열융착 관연결구를 제공하는 것이다.The present invention is to solve the problems as described above, an object of the present invention is to provide a heat-sealed tube connector of excellent quality without shorting the heating wire during the heat-sealing of the connector.

본 고안에 따르면, 관체(10)와 관체(10)가 연결관(3)에 열융착 접속되도록 융착링(20)에 일정간격으로 감겨진 전열선(2)을 포함하여 구성된 열융착 관연결구에 있어서, 상기 전열선(2)은 그 외주면이 테프론 등과 같이 내열성이 우수한 수지재로 코팅(4)된 것을 특징으로 하는 열융착 관연결구가 제공된다.According to the present invention, in the heat-sealing tube connector configured to include a heating wire (2) wound around the fusion ring 20 at a predetermined interval so that the tube body 10 and the tube body 10 is heat-sealed to the connecting pipe (3) , The heating wire (2) is provided with a heat-sealed pipe connector, characterized in that the outer peripheral surface is coated (4) with a resin material excellent in heat resistance, such as Teflon.

이하, 본 고안의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다. 도 2는 본 발명의 일실시예에 따른 열융착 관연결구의 단면도이다. 이를 참조하면, 상기 열융착 관연결구는 주벽면에 단자삽입공(16)과 관찰공(12)이 관통 형성된 연결관(3)과, 전열선(2)이 감겨져 상기 연결관(3) 내부 양측에 끼움 결합되는 한 쌍의 융착링(20)으로 이루어진다. 또, 상기 융착링(20)에 감겨진 전열선(2) 양단에는 연결관(3)의 단자삽입공(16)을 통해 외부로 돌출되는 접속단자(14)가 마련된다.Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows. 2 is a cross-sectional view of a heat-sealed pipe connector according to an embodiment of the present invention. Referring to this, the heat-sealed tube connector is connected to the connecting tube (3) formed through the terminal insertion hole 16 and the observation hole 12 on the main wall surface, the heating wire (2) is wound on both sides of the inside of the connecting tube (3) Consists of a pair of fusion ring 20 to be fitted. In addition, the both ends of the heating wire (2) wound around the fusion ring 20 is provided with a connection terminal 14 protruding to the outside through the terminal insertion hole 16 of the connection pipe (3).

상기 전열선(2)은 그 외주면이 테프론 수지 등과 같이 내열성이 우수한 수지재로 1차 코팅(4)되어 300℃ 이상의 온도에서 20분 이상 견딜 수 있도록 되고 그 표면에 융착링(20)과 동일한 열가소성 합성수지재로 2차 코팅(5)된다.The heating wire 2 is a thermoplastic synthetic resin whose outer peripheral surface is first coated with a resin material having excellent heat resistance, such as Teflon resin, so that it can withstand 20 minutes or more at a temperature of 300 ° C. or more and the same as the fusion ring 20 on the surface thereof. Ash secondary coating 5 is carried out.

따라서, 상기 연결관(3)의 양측에 한 쌍의 파이프(10)를 끼움 결합하고 테프론이 균일하게 코팅된 전열선(2)에 전원을 공급하여 융착링(20)을 가열하면, 상기 전열선(2)에 의해 가열된 용융에 의해 파이프(10)가 연결관(3)에 밀폐되도록 융착 결합된다. 이때, 상기 전열선(2)은 융착링(20)과 동일한 2차 코팅(5)재인 열가소성 합성수지재가 용융되어 전열선(2)이 서로 접촉되더라도 용융점이 높은 테프론 수지로 1차 코팅(4)이 이루어져 있어 숏트가 발생되지 않고, 융착링(20)이 효과적으로 가열 용융되므로 파이프(10)가 연결관(3)에 균일하게 밀폐되도록 융착 결합된다.Therefore, when a pair of pipes 10 are fitted to both sides of the connection pipe 3 and the power is supplied to the heating wire 2 coated with Teflon uniformly to heat the fusion ring 20, the heating wire 2 The pipe 10 is fusion bonded so that the pipe 10 is sealed to the connecting pipe 3 by melting heated by At this time, the heating wire (2) is made of the first coating (4) made of Teflon resin having a high melting point, even if the thermoplastic synthetic resin material of the same secondary coating (5) material and the heating wire (2) is the same as the fusion ring 20 is melted Since no short is generated and the fusion ring 20 is effectively heated and melted, the pipe 10 is fusion-bonded to uniformly seal the connection pipe 3.

이상에서와 같이 본 고안에 의하면, 상기 열융착 관연결구는 융착링을 가열시키는 전열선의 외주면이 내열성이 우수한 테프론 수지로 균일하게 1차 코팅되어져 있어 용융에 의해 전열선이 서로 접촉되더라도 전열선간에 숏트가 발생되지 않고 융착링이 효과적으로 가열되어 관체가 연결구에 밀폐되도록 융착 결합되므로 품질이 우수하다.As described above, according to the present invention, the thermal fusion splicing connector is uniformly primary coated with Teflon resin having excellent heat resistance on the outer circumferential surface of the heating wire for heating the fusion ring, so that a short circuit occurs between heating wires even when the heating wires are contacted with each other by melting. Since the fusion ring is effectively heated and the pipe is fused to seal the connector, the quality is excellent.
