연료필터의 컨넥터구조{Structure of fuel filter connector}Structure of fuel filter connector

본 발명은 연료필터의 컨넥터구조에 관한 것으로서, 특히 엔진으로부터 연장되는 연료관을 컨넥터하우징에 삽입할때 작동피스톤이 밀리면서 연료통로와 연결되어 연료가 엔진으로 공급되고, 연료관을 컨넥터하우징으로부터 이탈시키면 작동피스톤이 연료통로로부터 빠지면서 연료가 유출되지 않도록하여 엔진의 시동성능 확인 동작 후 연료필터의 컨넥터로부터 연료관을 이탈시키더라도 필터 내부에 존재하는 연료가 외부로 유출되지 않도록 한 연료필터의 컨넥터구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector structure of a fuel filter. In particular, when the fuel pipe extending from the engine is inserted into the connector housing, the operating piston is pushed, connected to the fuel passage, fuel is supplied to the engine, and the fuel pipe is separated from the connector housing. The fuel filter's connector structure prevents fuel from leaking out from the fuel filter's connector after the operating piston is pulled out of the fuel passage so that fuel does not flow out. It is about.

연료필터는 연료펌프에서 펌핑되는 연료를 필터링하여 이물질을 걸러낸 후 엔진 측으로 공급하는 것이며, 이러한 연료필터에는 엔진측으로부터 연장되는 연료관의 결합을 위한 컨넥터가 형성되어 있다.The fuel filter filters the fuel pumped from the fuel pump to filter foreign substances and then supplies them to the engine side. The fuel filter is provided with a connector for coupling a fuel pipe extending from the engine side.

도 4 는 종래의 연료필터의 컨넥터구조를 도시한 것으로서,4 illustrates a connector structure of a conventional fuel filter,

필터케이스(1)의 내부에 엘리먼트측과 연료펌프 측을 상호 연결하는 연료통로(2)가 형성되어 있으며, 필터케이스(1)의 일측에는 상기 연료통로(2)와 연통되는 파이프 형상의 컨넥터(3)가 형성되어 있다.A fuel passage 2 is formed inside the filter case 1 to interconnect the element side and the fuel pump side, and one side of the filter case 1 has a pipe-shaped connector communicating with the fuel passage 2. 3) is formed.

그러나, 종래의 컨넥터구조는 연료통로(2) 내에 존재하는 연료가 외부로 유출되지 못하도록 차단하는 장치가 구비되어 있지 않기 때문에 엔진 조립후 이루어지는 시동성능 테스트의 완료 후 연료통로(2)에 남아있는 연료가 필터케이스(1) 외부로 유출되어 주변을 오염시키게되는 문제점이 발생하고 있었다.However, since the conventional connector structure is not provided with a device for preventing the fuel present in the fuel passage 2 from leaking to the outside, the fuel remaining in the fuel passage 2 after completion of the starting performance test performed after the engine is assembled. Was leaked to the outside of the filter case 1 to contaminate the surroundings.

즉, 엔진 조립후에는 엔진의 시동성능을 확인하기 위해 시동성능 테스트를 실시하게 되는데, 시동성능 테스트를 할 때에는 연료펌프에 일정양의 연료를 주입한 후 연료필터의 컨넥터에 연료관을 삽입하여 연료펌프에서 펌핑되는 연료가 엔진에 공급되도록 한 상태에서 엔진의 시동성능을 테스트하며 시동성능 테스트가 완료된 후에는 연료필터의 컨넥터로부터 연료관을 이탈시키게 되는데, 이때 상기 연료관이 컨넥터로부터 이탈됨과 동시에 연료통로(2)에 남아있는 연료가 컨넥터(3)를 통해 외부로 유출되어 주변을 오염시키게 되는 것이다.In other words, after assembling the engine, a starting performance test is performed to check the starting performance of the engine.In the starting performance test, a certain amount of fuel is injected into the fuel pump, and a fuel pipe is inserted into the fuel filter connector. The engine is tested for starting performance while fuel pumped from the pump is supplied to the engine, and after the starting performance test is completed, the fuel pipe is detached from the connector of the fuel filter. The fuel remaining in the furnace 2 is leaked to the outside through the connector 3 to pollute the surroundings.

또한, 상기와같이 연료가 유출되는 것을 방지하기 위해서는 시동성능 테스트를 완료한 후 연료관을 컨넥터로부터 이탈시킬때 연료통로(2)에 남아있는 모든 연료를 빼내는 작업을 별도로 실시해야만 하므로 그만큼 작업성이 떨어지는 문제점이 발생하고 있었다.In addition, in order to prevent the outflow of fuel as described above, when the fuel pipe is removed from the connector after completing the start-up performance test, it is necessary to separately remove all fuel remaining in the fuel passage (2). The falling problem was occurring.

따라서, 상기 문제점을 해결하기 위한 본 발명은 필터케이스의 결합부 내에 원통형의 컨넥터하우징을 삽입하고, 필터케이스 내의 연료통로와 선택적으로 연결되는 작동피스톤을 컨넥터하우징의 내측으로 슬라이딩 이동가능하게 삽입하므로서, 엔진으로부터 연장되는 연료관을 컨넥터하우징에 삽입할때 작동피스톤이 밀리면서 연료통로와 연결되어 연료가 엔진으로 공급되고, 연료관을 컨넥터하우징으로부터 이탈시키면 작동피스톤이 연료통로로부터 빠지면서 연료가 유출되지 않도록하여 엔진의 시동성능 확인 동작 후 연료필터의 컨넥터로부터 연료관을 이탈시키더라도 필터 내부에 존재하는 연료가 외부로 유출되지 않도록 한 연료필터의 컨넥터구조를 제공함을 목적으로 한다.Therefore, the present invention for solving the above problems by inserting the cylindrical connector housing in the coupling portion of the filter case, by inserting the operation piston selectively connected to the fuel passage in the filter case so as to slide inwardly of the connector housing, When the fuel pipe extending from the engine is inserted into the connector housing, the working piston is pushed and connected to the fuel passage so that the fuel is supplied to the engine.If the fuel pipe is removed from the connector housing, the operating piston is pulled out of the fuel passage to prevent the fuel from flowing out. Accordingly, an object of the present invention is to provide a connector structure of a fuel filter such that fuel existing in the filter does not leak out even when the fuel pipe is separated from the connector of the fuel filter after the operation of checking the starting performance of the engine.

이하, 첨부된 도면 도 1 내지 도 3 을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 1 to 3.

상기 도면에 의하면, 도면부호 10 은 필터케이스를 나타내며, 이 필터케이스(10)의 내부에는 연료의 유동이 이루어지는 연료통로(11)가 형성되어 있다.According to the drawing, reference numeral 10 denotes a filter case, and a fuel passage 11 through which fuel flows is formed inside the filter case 10.

상기 필터케이스(10)의 일측에 컨넥터하우징(20)의 결합을 위한 결합부(12)를 요입형성하는데, 이때, 결합부(12)의 일측 끝단에 환형으로 돌부(13)를 내향 돌출시켜 이 돌부(13)의 사이 공간에 연료통로(11)와 연결되는 연통홀(14)이 형성되도록 한다.The coupling part 12 for coupling the connector housing 20 to one side of the filter case 10 is formed in a concave, at this time, by protruding the protrusion 13 inwardly in an annular shape at one end of the coupling part 12. A communication hole 14 connected to the fuel passage 11 is formed in the space between the protrusions 13.

도면부호 20은 상기 결합부(12)에 삽입되는 컨넥터하우징을 나타내며, 컨넥터하우징(20)의 내측 중간부분에는 단차부(23)가 형성되며, 끝단에는 후설하는 밀폐링(22)이 지지되기 위한 경사면(21)이 형성된다.Reference numeral 20 denotes a connector housing inserted into the coupling part 12, and a stepped part 23 is formed at an inner middle portion of the connector housing 20, and a sealing ring 22 to be installed at the end is supported. The inclined surface 21 is formed.

상기 컨넥터하우징(20)의 내부로는 도 3 에 도시한 바와같이 원통형으로 형성된 작동피스톤(30)이 슬라이딩 이동가능하게 삽입되는데, 이 작동피스톤(30)의 외측에는 별도의 스프링(31)을 삽입하여 이 스프링(31)에 의해 작동피스톤(30)이 컨넥터하우징(20)의 개구부 측으로 움직일 수 있도록 한다.As shown in FIG. 3, the connector housing 20 has a cylindrical working piston 30 slidably inserted therein, and a separate spring 31 is inserted into the outer side of the working piston 30. The spring 31 allows the operation piston 30 to move toward the opening side of the connector housing 20.

상기 스프링(31)은 그 일측이 컨넥터하우징(20)의 내측에 형성된 단차부(23)에 지지되고 타측은 작동피스톤(30)의 일측 끝단에 지지되도록 한다.The spring 31 has one side supported by the stepped portion 23 formed inside the connector housing 20 and the other side supported by the one end of the working piston 30.

상기 작동피스톤(30)의 작동단에는 연통홀(14)을 선택적으로 개폐하기 위한 삽입부(32)를 돌출 형성하되, 이 삽입부(32)의 외주연에 복수의 통공(34)을 형성하여 삽입부(32)가 연료통로(11) 내측으로 삽입되었을때 상기 통공(34)을 통해 연료가 이동되도록 하였다.An actuating end of the actuating piston 30 may protrude and form an insertion part 32 for selectively opening and closing the communication hole 14, and forming a plurality of through holes 34 on the outer circumference of the insertion part 32. When the insertion part 32 is inserted into the fuel passage 11, the fuel is moved through the through hole 34.

한편, 상기 삽입부(32)의 외측과 컨넥터하우징(20)의 사이에 연료 누출을 방지하기위한 밀폐링(22) 형성하며, 삽입부(32)의 외주연에는 상기 밀폐링(22)에 걸리면서 작동피스톤(30)이 컨넥터하우징(20)으로부터 이탈되지 않도록 잡아주는 단턱(33)을 형성하였다.Meanwhile, a sealing ring 22 is formed between the outer side of the inserting portion 32 and the connector housing 20 to prevent fuel leakage, and the outer periphery of the inserting portion 32 is caught by the sealing ring 22. The stepped piston 33 is formed to hold the operating piston 30 from being detached from the connector housing 20.

이와같이 구성된 본 발명의 동작을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.

엔진 조립 후 엔진의 시동성 테스트를 위해 연료탱크에 일정양의 연료를 주입하고, 엔진으로부터 연장되는 연료관을 컨넥터하우징(20)으로 삽입한다.After assembling the engine, a certain amount of fuel is injected into the fuel tank for starting test of the engine, and a fuel pipe extending from the engine is inserted into the connector housing 20.

상기 연료관이 컨넥터하우징(20) 내부로 삽입되면, 이 연료관에 의해 작동피스톤(30)이 스프링(31)의 탄성을 이기고 전진(도면상의 우측)하게 되므로 삽입부(32)가 도 2 에 도시된 바와같이 연료통로(11) 내부로 노출되게 되며, 이에의해 연료통로(11)를 통과하는 연료가 상기 삽입부(32)의 외주연에 형성되어 있는 통공(34)을 통해 배출되어 엔진으로 공급되게 된다.When the fuel pipe is inserted into the connector housing 20, the operation piston 30 is moved forward (right side in the drawing) and the elastic piston of the spring 31 by the fuel pipe so that the insert 32 is shown in FIG. As shown, the fuel passage 11 is exposed to the inside, whereby the fuel passing through the fuel passage 11 is discharged through the through hole 34 formed in the outer periphery of the insertion portion 32 to the engine Will be supplied.

상기와같이 작동피스톤(30)이 컨넥터하우징(20)의 안쪽으로 삽입되면, 작동피스톤(30)의 단부(35)가 밀폐링(22)을 결합부(12)의 돌부(13)에 밀착시키게 되므로 통공(34)통해 연료가 엔진으로 공급되는 과정에서 연료의 누출현상이 발생하지 않게된다.When the actuating piston 30 is inserted into the connector housing 20 as described above, the end 35 of the actuating piston 30 causes the sealing ring 22 to closely contact the protrusion 13 of the engaging portion 12. Therefore, the leakage of fuel does not occur while the fuel is supplied to the engine through the through hole 34.

한편, 엔진 시동성 테스트가 완료되면, 연료관을 컨넥터하우징(20)으로부터 이탈시키게되는데, 상기와같이 연료관이 컨넥터하우징(20)으로부터 완전히 빠지게되면, 도 1 에 도시한바와같이 스프링(31)의 탄성에 의해 작동피스톤(30)이 컨넥터하우징(20)의 개방부측(도면상의 좌측)으로 밀려나게되며, 이에의해 삽입부(32)가 연통홀(14)을 완전히 차단하게 되므로 연료통로(11)에 남아있는 연료가 필터케이스(10)의 외부로 유출되지 않게된다.On the other hand, when the engine startability test is completed, the fuel pipe is detached from the connector housing 20. When the fuel pipe is completely removed from the connector housing 20 as described above, as shown in FIG. The actuation piston 30 is pushed to the open side (left side of the drawing) of the connector housing 20 by the elasticity, whereby the insertion portion 32 completely blocks the communication hole 14, so that the fuel passage 11 The fuel remaining in the filter case 10 is not leaked to the outside.

이상에서 설명한 바와같이 동작하는 본 발명을 이용하게 되면, 엔진 시동성 테스트시 연료관을 컨넥터 하우징(20)에 삽입함에 따라 연료통로(11)를 통과하는 연료가 연료관을 통해 엔진으로 공급되어 엔진의 시동성을 테스트하게되며, 테스트완료후에는 컨넥터하우징(20)으로부터 연료관을 분리하는 것에 의해 작동피스톤(30)의 삽입부(32)가 연통홀(14)을 차단하게되므로 연료통로에 남아있는 연료의 유출현상이 발생하지 않게되므로 엔진 시동성 테스트 작업을 보다 간편하게 수행할 수 있게된다.According to the present invention operating as described above, when the fuel pipe is inserted into the connector housing 20 during the engine startability test, the fuel passing through the fuel passage 11 is supplied to the engine through the fuel pipe to supply the engine. Start-up test is performed, and after completion of the test, the insert 32 of the operation piston 30 blocks the communication hole 14 by disconnecting the fuel pipe from the connector housing 20, thereby remaining fuel in the fuel passage. This prevents the leakage of oil and thus makes it easier to test the engine startability.

이상에서 설명한 바와같이 본 발명은 필터케이스의 결합부 내에 원통형의 컨넥터하우징을 삽입하고, 필터케이스 내의 연료통로와 선택적으로 연결되는 작동피스톤을 컨넥터하우징의 내측으로 슬라이딩 이동가능하게 삽입하므로서, 엔진으로부터 연장되는 연료관을 컨넥터하우징에 삽입할때 작동피스톤이 밀리면서 연료통로와 연결되어 연료가 엔진으로 공급되고, 연료관을 컨넥터하우징으로부터 이탈시키면 작동피스톤이 연료통로로부터 빠지면서 연료가 유출되지 않도록하여 엔진의 시동성능 확인 동작 후 연료필터의 컨넥터로부터 연료관을 이탈시키더라도 필터 내부에 존재하는 연료가 외부로 유출되지 않도록 한 연료필터의 컨넥터구조를 제공하는 효과를 기대할 수 있다.As described above, the present invention extends from the engine by inserting a cylindrical connector housing into the coupling portion of the filter case and slidably inserting an operation piston selectively connected to the fuel passage in the filter case to the inside of the connector housing. When the fuel pipe is inserted into the connector housing, the working piston is pushed and connected to the fuel passage so that the fuel is supplied to the engine.If the fuel pipe is removed from the connector housing, the operating piston is pulled out of the fuel passage so that fuel does not leak out. Even if the fuel pipe is detached from the fuel filter connector after the starting performance checking operation, the effect of providing the connector structure of the fuel filter which prevents the fuel present in the filter from leaking to the outside can be expected.
