도시한 바와 같이, 본 발명에 따른 수분 유입을 방지할 수 있는 엔진룸 정션박스는 몸체(10), 상부커버(20), 체결부재 등을 포함한다.As shown, the engine room junction box that can prevent the inflow of water according to the present invention includes a body 10, the upper cover 20, a fastening member and the like.

몸체(10)는 하측으로 함몰되어 공간을 형성하여 내부에 릴레이 소자와 퓨즈 등의 엔진부품이 내장된다. 몸체(10)의 테두리 상측면은 내측과 외측으로 돌출된 2중 구조의 돌출홈(12)이 형성되고, 돌출홈(12)의 바닥면에는 다수의 배수홈(13)이 형성된다. 또한, 몸체(10)의 하부일측에는 내부로 유입된 수분을 배출하기 위한 배수구(미도시)가 형성될 수 있다.The body 10 is recessed downward to form a space, and engine parts such as a relay element and a fuse are embedded therein. The upper surface of the rim of the body 10 is formed with a protrusion 12 having a double structure projecting inward and outward, and a plurality of drainage grooves 13 are formed at the bottom of the protrusion 12. In addition, a lower portion of the body 10 may be formed with a drain (not shown) for discharging the water introduced into the interior.

상부커버(20)는 몸체(10)의 상부를 커버할 수 있도록 배치되며, 상부커버(20)의 외측은 몸체(10)에 형성된 돌출홈(12)으로 연장되어 밀착되는 제1밀착면(21)과 제1밀착면(21)의 외측에서 몸체(10)의 외측면에 연장된 제2밀착면(23)으로 이루어진다. 이때, 제1밀착면(21)의 하부면에는 몸체(10)의 돌출홈(12) 사이로 연장되는 수분유입방지돌기(22)가 형성된다. 이러한 상부커버(20)는 몸체(10)의 일측 외측면에서 힌지결합되어 연결될 수 있다. 또한, 몸체(10)의 외측면에 밀착되는 제2밀착면(23)의 내측에 방수씰(미도시)을 형성하여 수분의 유입을 차단할 수 있다.The upper cover 20 is disposed to cover the upper portion of the body 10, the outer side of the upper cover 20 extends into the protruding groove 12 formed in the body 10 to be in close contact with the first contact surface 21. ) And a second contact surface 23 extending from the outside of the first contact surface 21 to the outer surface of the body 10. At this time, the lower surface of the first contact surface 21 is formed with a water inflow prevention projections 22 extending between the protruding grooves 12 of the body (10). The upper cover 20 may be hingedly coupled to one side of the outer surface of the body 10. In addition, by forming a waterproof seal (not shown) on the inner side of the second contact surface 23 in close contact with the outer surface of the body 10 can block the inflow of moisture.

한편, 체결부재는 몸체(10)의 외측면 형성된 몸체체결부(31)와 상부커버(20)의 외측면에 형성된 상부체결부(32)로 이루어지며, 상부커버(20)를 몸체(10)에 덮은 상태에서 상부체결부(32)와 몸체체결부(31)를 결합시켜 상부커버(20)가 이탈되지 않도록 체결된다. On the other hand, the fastening member is composed of the body fastening portion 31 formed on the outer surface of the body 10 and the upper fastening portion 32 formed on the outer surface of the upper cover 20, the upper cover 20 to the body 10 The upper fastening portion 32 and the body fastening portion 31 are coupled to each other so that the upper cover 20 is fastened so as not to be separated.

여기서, 몸체(10), 상부커버(20) 및 체결부재는 플라스틱 재질을 포함하는 PVC 재질 또는 강도가 높은 폴리카보네이트 재질 등으로 제작될 수가 있다.
Here, the body 10, the upper cover 20 and the fastening member may be made of a PVC material including a plastic material or a polycarbonate material having a high strength.

이하, 본 발명에 따른 수분 유입을 방지할 수 있는 엔진룸 정션박스에 대한 작용 및 효과를 설명하도록 한다.Hereinafter, the operation and effects on the engine room junction box that can prevent the inflow of water according to the present invention.

먼저, 엔진룸에 적용되는 정션박스의 내부에 릴레이 소자와 퓨즈 등의 엔진부품을 내장한다. 이러한 엔진부품은 바닥면과 소정거리 이격된 상태로 위치하는 것이 바람직하다.First, engine parts such as a relay element and a fuse are embedded in the junction box applied to the engine room. Such engine parts are preferably located at a distance from the bottom surface.

엔진부품의 내장이 완료되면 상부커버(20)의 제1밀착면(21)에 형성된 수분유입방지돌기(22)가 몸체(10)의 테두리에 형성된 2중 구조의 돌출홈(12) 사이에 놓여지도록 몸체(10)의 상부에 상부커버(20)를 결합시킨다. 이때, 상부커버(20)의 제2밀착면(23)은 몸체(10)의 테두리에서 외측면으로 연장되면서 결합되어 좌우 등으로 흔들리는 것을 방지한다.When the engine parts are completely built, the water inflow preventing protrusion 22 formed on the first contact surface 21 of the upper cover 20 is placed between the double grooves 12 formed in the rim of the body 10. The upper cover 20 is coupled to the upper portion of the body 10 to lose. At this time, the second contact surface 23 of the upper cover 20 is coupled to extend from the edge of the body 10 to the outer surface to prevent shaking from side to side and the like.

한편, 몸체(10)와 상부커버(20)가 결합되면 몸체(10)의 외측면과 상부커버(20)의 외측면에 각각 형성된 상부체결부(32)와 몸체체결부(31)를 결합시켜 상부커버(20)의 결합이 완료된다.On the other hand, when the body 10 and the upper cover 20 are coupled to each other by coupling the upper fastening portion 32 and the body fastening portion 31 formed on the outer surface of the body 10 and the outer surface of the upper cover 20, respectively The coupling of the upper cover 20 is completed.

이와 같이, 몸체(10)와 상부커버(20)의 결합이 완료되어 수분이 유입되는 경우에 유입되는 수분은 몸체(10)의 외측면과 상부커버(20)의 제2밀착면(23) 사이를 통해 상부방향으로 이동하기 때문에 쉽게 유입될 수 없다(1차 수분 유입저지). 또한, 몸체(10)의 테두리 상측면으로 이동된 수분은 상부커버(20)의 제1밀착면(21)에 형성될 수분유입방지돌기(22)에 의해 더 이상 내측으로 이동되지 못하고 수분유입방지돌기(22)의 아래에 형성된 2중 구조의 돌출홈(12)으로 낙하하게 된다(2차 수분 유입저지). As such, when the coupling of the body 10 and the upper cover 20 is completed and the moisture is introduced, the moisture introduced is between the outer surface of the body 10 and the second contact surface 23 of the upper cover 20. It can not be easily introduced because it moves upward through (primary moisture inlet). In addition, the water moved to the upper side of the rim of the body 10 is no longer moved to the inside by the water inflow prevention projections 22 to be formed on the first contact surface 21 of the upper cover 20 to prevent water inflow Falling into the projection 12 of the dual structure formed under the projection 22 (secondary water inlet blocking).

그리고, 돌출홈(12) 내부로 낙하된 수분은 3차로 돌출홈(12) 내부에 형성된 배수홈(13)을 따라 몸체(10)의 하단으로 이동되고 하단에 형성된 배수구를 통해 배출된다(3차 수분 유입저지).
Then, the water dropped into the protruding groove 12 is moved to the lower end of the body 10 along the drain groove 13 formed in the protruding groove 12 and discharged through the drain hole formed at the lower end (third Moisture intake).

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
