본 발명은 스타터 전원회로가 내장되는 차량의 정션박스에 관한 것으로, 더 자세하게는 차량의 차체 내부 전방 일측에 설치되는 정션박스의 내부에 수분이 유 입되어 정션박스에 내장된 각종 회로 및 부품이 손상되는 것을 방지할 수 있도록 하는 차량의 스타터 전원회로 내장 정션박스 보호구조에 관한 것이다.The present invention relates to a junction box of a vehicle in which a starter power circuit is embedded, and more particularly, moisture is introduced into the junction box installed at one side in front of the vehicle body to damage various circuits and components embedded in the junction box. The present invention relates to a junction box protection structure incorporating a starter power circuit of a vehicle, which can be prevented.

본 발명은 특히 차량의 차체 내부 전방 일측에 설치되고 스타터 전원회로가 내장되는 정션박스에 관계하는 것인 바, 종래에 있어서는 차체 응결수 및 누수에 의한 수분 유입으로 정션박스 내의 회로 단락과 회로기판(PCB) 부식 등이 발생할 우려가 많았으며, 특히 정션박스에 내장된 스타터 전원회로의 단락으로 인하여 예상치 못한 스타터모터의 구동이 발생하게 되는 등의 문제가 있었다.In particular, the present invention relates to a junction box installed at one side of the vehicle body in front of the vehicle and having a starter power circuit built therein. Corrosion, etc., was likely to occur. In particular, there was a problem such as unexpected starter motor driving due to a short circuit in the starter power circuit built in the junction box.

이러한 정션박스의 수분 유입 현상은 유럽과 같이 새벽이나 야간에 비가 내리고 낮기온이 높은 지역, 저온 다습하고 일교차 및 차량 내부의 온도 변화가 심한 지역에서 많이 발생하게 된다.The moisture inflow of the junction box is often generated in areas where rain and rain are high at low or high temperatures, low temperature and high humidity, day crossings, and severe temperature changes inside the vehicle, such as Europe.

정션박스의 수분 유입의 원인은 첫째 차체 누수로 인한 물 유입, 둘째 차체 내부 응결수 유입, 셋째 회로기판 결로현상에 따른 수분 유입을 들 수 있으며, 전술한 바와 같이 유럽과 같은 해외의 특정지역, 겨울시즌에 집중적으로 발생하게 된다.The inflow of water into the junction box may include water inflow from the first body leakage, condensation water in the second body, and water inflow due to condensation on the circuit board. It happens intensively during the season.

예를 들어 야간 외부 기온이 -5℃인 상태에서 주간에 차내 온도가 +5℃로 상승하게 되면 포화수증기 차체 내벽 응결 습도가 100%에 이르게 되며, 이렇듯 차량 내, 외부 온도차가 심할 경우 많은 응결수가 발생하게 된다.For example, if the temperature inside the car rises to + 5 ° C during the day when the outside temperature is -5 ° C at night, the condensation humidity of the inner wall of the saturated steam body reaches 100%. Will occur.

정션박스 내부로 수분이 유입되면 회로기판이 부식되고 쇼트가 발생하게 되며, 예기치 않은 상황에서 스타터 모터가 구동될 수 있고, 와이퍼나 각종 램프류, 오디오, 에어백 등이 작동 불능상태에 빠질 수 있게 된다.If moisture enters the junction box, the circuit board may be corroded and short-circuited, the starter motor may be driven in unexpected situations, and the wiper, various lamps, audio, airbags, etc. may become inoperable.

그런데 종래에 있어서는 도 1과 같이 후방 상부에 도어그로멧(30')이 접속되는 아우터커버(20')의 내부 전방 중앙에 정션박스(10')가 별다른 보호구조 없이 설치됨으로써 누수 및 응결수 등의 수분이 아우터커버(20')의 내부로 유입되는 경우 그 대부분이 정션박스(10')에 작용하게 되어 그에 내장된 회로 및 부품을 손상시키게 되는 문제가 있었다.However, in the related art, the junction box 10 'is installed in the inner front center of the outer cover 20' to which the door grommet 30 'is connected to the rear upper portion without any protection structure, such as water leakage and condensation. When moisture is introduced into the outer cover 20 ', most of them act on the junction box 10', thereby damaging circuits and components embedded therein.

본 발명은 상기와 같은 종래의 실정을 감안하여 안출한 것이며, 그 목적이 스타터 전원회로가 내장된 정션박스의 내부에 차체 누수나 응결수, 결로현상 등을 통해 발생된 수분이 유입되는 것을 방지할 수 있도록 하여 정션박스 내부의 각종 회로 및 부품을 보호할 수 있도록 하는 차량의 스타터 전원회로 내장 정션박스의 보호구조를 제공하는 데에 있는 것이다.The present invention has been made in view of the conventional situation as described above, the purpose of which is to prevent the inflow of moisture generated through the vehicle body leakage, condensation water, condensation, etc. inside the junction box with a starter power supply circuit. The purpose of the present invention is to provide a protection structure of a junction box with a built-in starter power circuit of a vehicle to protect various circuits and components inside the junction box.

본 발명은 상기의 목적을 달성하기 위하여 아우터커버의 내부 상부에 수분유입 방지턱을 형성함과 아울러 정션박스의 상단부를 둘러쌀 수 있도록 하는 인너커버를 설치하고, 아우터커버의 내부 후방 상부에 도어그로멧과 접속되는 실내그로멧을 설치하는 것을 특징으로 하며, 이하 그 구체적인 기술내용을 첨부도면에 의거하여 더욱 자세히 설명하면 다음과 같다.In order to achieve the above object, the present invention provides an inner cover for forming a moisture inflow prevention jaw on the inner upper portion of the outer cover and surrounding the upper end of the junction box, and a door grommet on the inner rear upper portion of the outer cover. It is characterized in that the indoor grommet to be connected, and the following detailed description thereof in detail based on the accompanying drawings.

즉, 도 2에는 본 발명의 한 실시예에 따른 정션박스 장착상태도가 도시되어 있고, 도 3에는 동 실시예의 요부 분해 사시도가 도시되어 있는 바, 본 발명은 후방 상부에 도어그로멧(30)이 접속되는 아우터커버(20)의 전방 중앙에 스타터 전원회로가 내장되는 정션박스(10)를 설치하되, 상기 아우터커버(20)의 내부 상부에 수분유입 방지턱(21)을 형성하고, 수분유입 방지턱(21)의 하부에 정션박스(10)의 상단부를 둘러쌀 수 있도록 하는 인너커버(40)를 설치하고, 아우터커버(10)의 내부 후방 상부에 도어그로멧(30)과 접속되는 실내그로멧(50)을 설치하여서 되는 것이다.That is, Fig. 2 is a state diagram showing a junction box mounting according to an embodiment of the present invention, Figure 3 is an exploded perspective view of the main portion of the embodiment bar, the present invention is connected to the door grommet 30 in the rear upper portion The junction box 10 in which the starter power circuit is built is installed in the front center of the outer cover 20, but the moisture inflow prevention jaw 21 is formed on the inner upper portion of the outer cover 20, and the moisture inflow prevention jaw 21 is provided. The inner cover 40 is installed at the lower portion of the junction box 10 so as to surround the upper end of the junction box 10, and the indoor grommets 50 connected to the door grommets 30 at the inner rear upper portion of the outer cover 10. By installation.

도면부호중 미설명부호 31은 그로멧인너, 61은 실내측 커넥터, 62는 도어측 커넥터이다.Reference numeral 31 in the drawings denotes a grommet inner, 61 an indoor connector, and 62 a door connector.

상기와 같이 구성된 본 발명에 있어서는 도 2와 같이 아우터커버(20)의 내부 상단부로 유입되는 수분이 수분유입 방지턱(21)과 인너커버(40)를 통해 정션박스(10)가 설치된 아우터커버(20) 내부 전방 쪽이 아닌 아우터커버(20)의 내부 후방 쪽으로 유도될 뿐 아니라 아우터커버(20)의 상단 후방에서 낙하되는 수분이 실내그로멧(50)을 통해 아우터커버(20)의 내부로 진입되지 않고 아우터커버(20)의 외측으로 유도되는 등 아우터커버(20)의 외부에서 발생되어 아우터커버(20)쪽으로 작용하는 외부의 수분이 아우터커버(20)의 내부 전방 중앙에 설치되는 정션박스(10)에 유입되는 것을 확실하게 차단할 수 있게 된다.In the present invention configured as described above, as shown in FIG. 2, the water flowing into the upper upper end of the outer cover 20 is provided with the junction box 10 through the moisture inflow preventing jaw 21 and the inner cover 40. In addition to being guided toward the inner rear of the outer cover 20 instead of the inner front side, water falling from the upper rear of the outer cover 20 does not enter the inside of the outer cover 20 through the indoor grommets 50. Junction box 10 that is generated from the outside of the outer cover 20, such as guided to the outside of the outer cover 20, acting toward the outer cover 20 is installed in the inner front center of the outer cover 20 It can be reliably blocked from entering.

따라서 본 발명에 있어서는 정션박스(10)에 내장되는 스타터 전원회로를 비롯한 각종 회로 및 부품을 수분으로부터 안전하게 보호할 수 있게 된다.Therefore, in the present invention, various circuits and components including the starter power circuit built in the junction box 10 can be safely protected from moisture.

이상에서와 같이 본 발명은 아우터커버(20)의 내부 상부에 수분유입 방지턱(21)을 형성하고, 수분유입 방지턱(21)의 하부에 정션박스(10)의 상단부를 둘러쌀 수 있도록 하는 인너커버(40)를 설치하고, 아우터커버(10)의 내부 후방 상부에 도어그로멧(30)과 접속되는 실내그로멧(50)을 설치한 것으로, 본 발명에 의하면 아우터커버(20)의 외부로부터 유입되는 수분이 정션박스(10)로 흘러들어가는 것을 완벽하게 차단할 수 있게 되므로 정션박스(10)에 내장된 각종 회로가 기능 정지되거나 오동작하는 일을 방지할 수 있게 되고, 각 부품 및 회로기판의 수명을 크게 연장할 수 있게 되며, 그에 따라 차량의 신뢰성 및 상품성 향상에 크게 기여할 수 있게 되는 등의 효과를 얻을 수 있게 된다.As described above, the present invention forms a moisture inflow prevention jaw 21 in the upper portion of the outer cover 20, and an inner cover to surround the upper end of the junction box 10 in the lower portion of the moisture inflow prevention jaw 21. 40 is installed, and the indoor grommets 50 connected to the door grommets 30 are installed on the inner rear upper portion of the outer cover 10. According to the present invention, water flowing from the outside of the outer covers 20 is provided. Since the flow to the junction box 10 can be completely blocked, various circuits built in the junction box 10 can be prevented from functioning or malfunctioning, and the life of each component and the circuit board can be greatly extended. It is possible to achieve this, and thus it is possible to obtain an effect such as to greatly contribute to the improvement of the reliability and the merchandise of the vehicle.
