Description

호스연결용 컨넥터{.}Connector for hose connection {.}

본 발명은 유체가 흐르는 호스를 연결하는 호스연결용 컨넥터에 관한 것으로서, 좀 더 구체적으로는 기밀 유지를 위해 수용공간내에 설치되는 오링의 접속면이 사출 성형시 변형되지 않는 구조를 갖는 호스연결용 컨넥터에 관한 것이다.The present invention relates to a hose connection connector for connecting a fluid flowing hose, more specifically, a hose connection connector having a structure in which the connection surface of the O-ring installed in the receiving space for airtightness does not deform during injection molding. It is about.

일반적으로 금속재의 파이프를 연결시에는 파이프의 연결부위에 숫나사산을 형성한 다음 숫나사산에 씨일(Seal)을 감은 후 금속재질로 이루어진 컨넥터의 암나사산에 나사 결합하게 되지만, 합성수지재의 호스인 경우에는 컨넥터내에 오링 및 콜릿(Collet)을 차례로 삽입한 다음 상기 콜릿내에 호스를 밀어 넣기만 하면 호스의 연결작업이 이루어지게 되므로 근래에는 정수기 등의 설치작업에 널리 사용되고 있다.Generally, when connecting a metal pipe, a male thread is formed on the connection part of the pipe, then a seal is wound around the male thread, and then screwed onto the female thread of the metal connector, but in the case of a synthetic resin hose O-rings and collets are inserted into the connectors in turn, and the hoses are connected by simply pushing the hoses into the collets. Thus, the hoses are widely used for installation of water purifiers.

상기한 바와 같은 역할을 하는 컨넥터의 구조를 첨부된 도 1 및 도 2를 참고하여 설명하면 다음과 같다.Referring to the structure of the connector that serves as described above with reference to Figures 1 and 2 as follows.

합성수지로 사출 성형된 본체(1)의 양단에 캡(2)(3)이 초음파에 의해 융착 고정되어 있고 상기 캡에 의해 형성되는 단턱부(2a)(3a)에는 콜릿(4)(5)의 후크(4a)(5a)가 걸려 결합되어 있어 상기 본체에 형성되는 수용공간(6)(7)내에 기밀을 유지하기 위한 오링(8)(9)을 삽입한 다음 상기 콜릿(4)(5)의 내부에 호스(10)(11)를 삽입하면 상기 호스(10)(11)가 콜릿(4)(5)의 내부에 인써트된 지지부재(4b)(5b)에 걸려 빠지지 않게 됨과 동시에 호스(10)(11)의 외주면이 오링(8)(9)에 밀착되므로 호스(10)(11)의 연결부에서 기밀을 유지하게 된다.The caps 2 and 3 are fused and fixed by ultrasonic waves at both ends of the main body 1 injection-molded with synthetic resin, and the stepped portions 2a and 3a formed by the caps are provided with the collets 4 and 5, respectively. Hooks (4a) (5a) are hooked to engage the O-rings (8) (9) for retaining airtight in the receiving space (6) (7) formed in the main body and then the collet (4) (5) Inserting the hose (10) (11) in the interior of the hose (10), 11 is not caught in the support member (4b) (5b) inserted into the collet (4) (5) and at the same time the hose ( Since the outer circumferential surface of the 10 and 11 is in close contact with the O-rings 8 and 9, airtightness is maintained at the connection portions of the hoses 10 and 11.

이와 같이 본체(1)의 양단에 삽입되는 호스(10)(11)의 외경이 같을 경우에는 큰 문제가 발생되지 않지만, 호스의 외경()이 다를 경우에는 다음과 같은 문제점이 발생된다.As described above, when the outer diameters of the hoses 10 and 11 inserted at both ends of the main body 1 are the same, no big problem occurs. If) is different, the following problems occur.

즉, 다른 실시예로 도시한 도 3과 같이 본체(1)에 삽입되는 호스(10)(11)의 외경에 따라 플랜지부(12)(13)의 살두께가 동일해지도록 최적의 상태로 금형을 설계하면 플랜지부의 내부에 핀홀 등과 같은 결함이 발생되지 않지만, 이러한 경우에는 후공정인 캡(2)(3)의 접착공정시 플랜지부(12)의 외주면에 턱걸이가 형성되지 않아 기존의 초음파 융착기를 이용하여 캡(2)을 접착하지 못하게 되므로 반드시 초음파 융착기의 구조를 개선하여야만 된다.In other words, according to the outer diameter of the hose 10, 11 is inserted into the main body 1 as shown in Figure 3 shown in another embodiment the mold thickness in the optimum state so that the flesh thickness of the flange portion (12) 13 If the design does not cause defects such as pinholes inside the flange portion, in this case, the jaw is not formed on the outer circumferential surface of the flange portion 12 during the bonding process of the caps 2 and 3, which is a post-process. Since the cap 2 cannot be bonded using the fusion machine, the structure of the ultrasonic fusion machine must be improved.

또한, 캡(2)(3)이 융착되는 본체(1) 양면의 면적이 달라져 본체(1)의 양측에 캡(2)(3)을 융착할 때마다 초음파 세기를 재조절하여야 되었으므로 생산성의 저하를 초래하게 되었다.In addition, since the areas of both sides of the main body 1 to which the caps 2 and 3 are fused are different, the ultrasonic intensity must be readjusted every time the caps 2 and 3 are welded to both sides of the main body 1, thereby reducing productivity. Resulted in

따라서 본체(1)에 삽입되는 호스(10)(11)의 외경이 다르더라도 전술한 바와 같은 제조상의 문제점으로 인해 플랜지부(12)(13)의 외경이 동일하게 본체(1)를 구성하여 플랜지부(12)의 경계면에 턱걸이(14)가 형성되도록 하고 있는 실정이다.Therefore, even if the outer diameters of the hoses 10 and 11 inserted into the main body 1 are different, the outer diameters of the flange portions 12 and 13 are the same as the main body 1 due to the manufacturing problems described above. It is a situation that the chin 14 is formed in the boundary surface of the branch (12).

그러나 이러한 경우에도 다음과 같은 치명적인 문제점이 발생되었다.However, even in this case, the following fatal problem occurred.

외경이 큰 호스(11)가 삽입되는 본체(1)의 플랜지부(13) 두께를 최적의 상태로 금형 설계하기 때문에 외경이 작은 호스(10)가 삽입되는 플랜지부(12)의 두께가 두꺼워져 본체(1)의 사출 성형시 오링(8)이 위치되는 면에서 핀홀(Pin Hole) 등과 같은 결함이 발생되므로 호스(10)의 연결부에서 기밀을 유지하지 못하게 되고, 이에 따라 컨넥터로서 치명적인 결함인 누수가 발생되었다.Since the thickness of the flange portion 13 of the main body 1 into which the hose 11 with the large outer diameter is inserted is optimally designed, the thickness of the flange portion 12 into which the hose 10 with the small outer diameter is inserted becomes thick. When injection molding of the main body 1, a defect such as a pin hole occurs at the surface where the O-ring 8 is located, and thus it is impossible to maintain airtightness at the connection part of the hose 10, thereby leaking a fatal defect as a connector. Was generated.

따라서 사출 성형시 사출시간을 지연시키면 핀홀 등과 같은 결함 발생이 현저히 줄어들지만, 이러한 경우에는 생산성이 떨어져 생산원가가 상승되는 문제점이 발생된다.Therefore, if the injection time is delayed during injection molding, defects such as pinholes are significantly reduced, but in this case, productivity is reduced and production costs are increased.

본 발명은 종래의 이와 같은 문제점을 해결하기 위해 안출한 것으로서, 본체의 양측에 위치되는 플랜지부의 경계면에 턱걸이가 형성되도록 외경을 동일하게 구성하고도 오일이 위치되는 수용공간의 내주면에 핀홀 등과 같은 결함이 발생되지 않도록 하는데 그 목적이 있다.The present invention has been made to solve such a problem in the prior art, the outer diameter of the same configuration so that the jaw is formed on the boundary surface of the flange portion located on both sides of the main body, such as a pinhole on the inner circumferential surface of the receiving space The purpose is to prevent defects from occurring.

상기 목적을 달성하기 위한 본 발명의 형태에 따르면, 본체의 호스 연결부위에 캡이 초음파 융착 고정되는 컨넥터에 있어서, 캡의 융착면상에 링형상의 공간부를 형성하여 플랜지부가 타측 플랜지부의 두께와 일치되는 내측플랜지부와 외부플랜지부로 분할 형성되도록 하고 상기 캡에는 공간부에 삽입되는 날개편이 형성된 것을 특징으로 하는 호스연결용 컨넥터가 제공된다.According to the aspect of the present invention for achieving the above object, in the connector in which the cap is ultrasonically fused fixed to the hose connection portion of the main body, by forming a ring-shaped space portion on the fusion surface of the cap, the flange portion matches the thickness of the other flange portion The inner flange portion and the outer flange portion to be formed is divided into the hose is provided with a connector for connecting the hose, characterized in that the wing piece is inserted into the space portion.

이하, 본 발명을 일 실시예로 도시한 도 4 및 도 5를 참고하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to FIGS. 4 and 5 as an embodiment.

도 4는 본 발명의 호스연결용 컨넥터를 나타낸 분해 사시도이고 도 5는 도 4의 결합상태 종단면도로서, 본 발명의 구성중 종래의 구성과 동일한 부분은 그 설명을 생략하고 동일 부호를 부여하기로 한다.Figure 4 is an exploded perspective view showing a hose connection connector of the present invention and Figure 5 is a longitudinal cross-sectional view of the coupled state of Figure 4, the same parts as the conventional configuration of the configuration of the present invention to omit the description and to give the same reference numerals do.

본 발명은 외경이 작은 호스(10)가 연결되는 플랜지부(12)측에 링형상의 공간부(15)가 형성되어 상기 플랜지부(12)가 타측 플랜지부(13)의 두께와 일치되는 내측플랜지부(12a)와 외부플랜지부(12b)로 분할 형성되어 있다.In the present invention, a ring-shaped space portion 15 is formed on the flange portion 12 side to which the hose 10 having a small outer diameter is connected, so that the flange portion 12 matches the thickness of the other flange portion 13. The flange portion 12a and the outer flange portion 12b are formed separately.

이와 같이 일측의 플랜지부(12)에 형성된 공간부(15)를 그대로 방치한 상태에서 캡(2)을 초음파 융착시키면 수압에 의해 내측플랜지부(12a)가 공간부측으로변형되어 누수가 발생되므로 이를 방지하기 위해 상기 플랜지부(12)에 초음파 융착 고정되는 캡(2)의 융착면상에는 공간부(15)에 삽입되는 날개편(2b)이 형성되도록 구성되어 있다.In this way, if the cap 2 is ultrasonically fused while the space 15 formed in the flange portion 12 on one side is left as it is, the inner flange portion 12a is deformed to the space side by water pressure and thus leaks are generated. On the fusion surface of the cap (2) which is ultrasonically fused to the flange portion 12 to prevent it is configured to form a blade piece (2b) is inserted into the space portion 15.

상기 공간부(15)는 호스(10)가 삽입되는 수용공간(6)과 동심원의 형태를 이루고 있다.The space part 15 forms a concentric circle with the accommodation space 6 into which the hose 10 is inserted.

따라서 본체(1)를 사출 성형하면 타측 플랜지부(13)의 살두께보다 두꺼운 일측의 플랜지부(12)가 공간부(15)에 의해 내측플랜지부(12a) 및 외측플랜지부(12b)로 분할 형성되어 있기 때문에 금형으로 흘러 들어간 수지가 균일하게 응고되므로 수용공간(6)의 내주면, 즉 오링(8)이 위치하는 면에서 두께의 편차에 따른 핀홀 등과 같은 결함이 발생되지 않는다.Therefore, when injection molding the main body 1, the flange portion 12 of one side thicker than the flesh thickness of the other flange portion 13 is divided by the space portion 15 into the inner flange portion 12a and the outer flange portion 12b. Since the resin flowing into the mold is solidified uniformly, defects such as pinholes due to variations in thickness do not occur in the inner circumferential surface of the accommodation space 6, that is, the surface where the O-ring 8 is located.

이와 같이 본체(1)가 사출 성형되고 나면 캡(2)의 융착면에 형성된 날개편(2b)을 공간부(15)내에 삽입한 다음 턱걸이(14)를 이용하여 본체(1)를 초음파 융착기에 지지한 상태에서 초음파 융착작업을 실시하므로써, 컨넥터의 생산이 완료된다.After the main body 1 is injection-molded in this manner, the blade piece 2b formed on the fusion surface of the cap 2 is inserted into the space 15, and then the main body 1 is inserted into the ultrasonic fusion splicer using the chin 14. Production of the connector is completed by performing the ultrasonic welding operation in the supported state.

상기한 바와 같은 구조를 갖는 컨넥터는 직선 컨넥터는 물론 엘보우 컨넥터, 티이 컨넥터 등 2개 이상의 호스가 연결되는 컨넥터에 전부 적용할 수 있게 됨은 이해 가능하다.It is to be understood that the connector having the structure as described above can be applied to all of the connectors to which two or more hoses, such as elbow connectors and tie connectors, as well as straight connectors are connected.

이상에서와 같이 얻어지는 본 발명의 컨넥터는 종래의 컨넥터에 비하여 다음과 같은 장점을 갖는다.The connector of the present invention obtained as described above has the following advantages over the conventional connector.

첫째, 오링(8)이 위치되는 수용공간(6)의 내경이 다르고 플랜지부(12)(13)의 외경이 같은 컨넥터에서 사출시간을 단축시키더라도 수지의 응고에 따른 편차가 발생되지 않으므로 오링(8)의 접속면에 핀홀 등과 같은 결함이 발생되지 않고, 이에 따라 호스(10)의 연결부위에서의 누수발생을 미연에 방지하게 된다.First, even if the inner diameter of the accommodating space 6 in which the O-ring 8 is positioned is different and the outer diameter of the flange parts 12 and 13 is shortened, the injection time does not occur and the deviation due to the solidification of the resin does not occur. Defects such as pinholes do not occur in the connection surface of 8), thereby preventing leakage in the connection portion of the hose 10 in advance.

둘째, 캡(2)의 융착작업시 캡의 접촉면적이 동일하여 초음파의 세기를 재조절할 필요가 없게 되므로 생산성을 향상시키게 된다.Second, the contact area of the cap during the fusion operation of the cap (2) is the same, so there is no need to readjust the intensity of the ultrasonic waves to improve the productivity.
