도 1 내지 도 4에 도시된 바와 같이 본 발명의 일 실시예에 따른 정션박스는 본체(10), 버스바(20) 및 탄성고정안내부(30)를 포함한다.As shown in FIGS. 1 to 4 , the junction box according to an embodiment of the present invention includes a main body 10 , a bus bar 20 and an elastic fixing guide part 30 .

본체(10)는 복수개의 스터드볼트(11)가 안착 가능하게 설치된다. 이러한 본체(10)는 차량의 종류별로 공용화 가능한 구조로 설계되고, 내부에 스터드볼트(11) 및 버스바(20) 뿐만 아니라, 인라인커넥터, PCB블록, 릴레이, 퓨즈 등과 같은 전장 부품이 실장되는 공간을 제공하는 역할을 수행한다. The main body 10 is installed so that a plurality of stud bolts 11 can be seated thereon. The main body 10 is designed as a structure that can be shared for each type of vehicle, and a space in which electrical parts such as stud bolts 11 and bus bars 20 as well as in-line connectors, PCB blocks, relays, and fuses are mounted. plays a role in providing

여기서, 스터드볼트(11)는 버스바(20) 및 전장 부품이 끼워지면 버스바(20)와 전장 부품이 상호 전기적으로 연결된 상태로 고정되도록 너트(N)가 체결된다.Here, when the bus bar 20 and the electrical component are inserted into the stud bolt 11, the nut N is fastened so that the bus bar 20 and the electrical component are electrically connected to each other and fixed.

이때, 스터드볼트(11)는 이탈방지부(40)에 의해 본체(10)에 이탈 방지되도록 안착될 수 있다.At this time, the stud bolt 11 may be seated in the main body 10 to be prevented from being separated by the separation prevention unit 40 .

구체적으로, 이탈방지부(40)는 본체(10)에 함몰 형성되는 안착홈부(41)와, 안착홈부(41)에 수용되도록 스터드볼트(11)에 돌출 형성되는 안착부재(42)와, 안착부재(42)가 안착홈부(41)에 수용시 안착부재(42)를 안착홈부(41)에 구속 가능하게 안내하는 구속안내부(43)를 포함한다. Specifically, the separation prevention unit 40 includes a seating groove 41 recessed into the main body 10, a seating member 42 protruding from the stud bolt 11 so as to be accommodated in the seating groove 41, and seating When the member 42 is accommodated in the seating groove 41, it includes a restraining guide 43 for guiding the seating member 42 to the seating groove 41 so as to be restrained.

이때, 안착홈부(41)와 안착부재(42)는 상호 대응되는 다각 형상으로 형성된다.At this time, the seating groove 41 and the seating member 42 are formed in a polygonal shape corresponding to each other.

또한, 구속안내부(43)는 구속안내부(43)는 안착홈부(41)의 내측 둘레면에 상호 마주보게 돌출 형성되는 걸림부재(43a) 및 걸림부재(43a)가 탄성적으로 수용되도록 안착부재(42)의 둘레면에 형성되는 걸림홈부(43b)를 포함한다. In addition, the restraint guide part 43 is seated so that the locking member 43a and the locking member 43a protruding from the inner circumferential surface of the seating groove 41 are elastically accommodated. It includes an engaging groove 43b formed on the circumferential surface of the member 42 .

즉, 걸림부재(43a)는 안착부재(42)가 안착홈부(41)에 안착되는 과정에서 안착부재(42)에 접촉되면 탄성적으로 변형되다가 안착부재(42)의 걸림홈부(43b)에 수용되는 순간 걸림홈부(43b)에 걸림 지지되어 안착부재(42)를 안착홈부(41)에 안착된 상태로 위치 고정시킨다.That is, the locking member 43a is elastically deformed when the mounting member 42 contacts the mounting member 42 in the process of being seated in the mounting groove 41, and then accommodated in the locking groove 43b of the mounting member 42. At the moment it is caught and supported by the locking groove 43b, the mounting member 42 is seated in the mounting groove 41 and fixed in position.

이로써, 스터드볼트(11)는 안착부재(42)와 안착홈부(41)의 결합을 통해 수평방향으로 회전이 방지될 뿐만 아니라, 걸림부재(43a)와 걸림홈부(43b)의 결합을 통해 수직 방향으로 이동이 방지되기 때문에 본체(10)에 안착된 상태를 유지할 수 있으므로, 조립 작업성을 향상시킬 수 있게 된다.Thus, the stud bolt 11 is not only prevented from rotating in the horizontal direction through the combination of the seating member 42 and the seating groove 41, but also in the vertical direction through the combination of the locking member 43a and the locking groove 43b. Since the movement is prevented, it is possible to maintain a seated state on the main body 10, thereby improving assembly workability.

그리고, 버스바(20)는 스터드볼트(11)에 끼움 결합되도록 끼움홀부(21)를 구비한다. 이러한 버스바(20)는 스터드볼트(11)가 삽입 고정되어 접점 유지를 통해 전장 부품들을 전기적으로 연결하는 것으로서, 얇은 판 형상을 가진 금속 재질의 도체로 이루어진다. In addition, the bus bar 20 has fitting holes 21 to be fitted to the stud bolts 11. Such a bus bar 20 electrically connects electric components through contact retention by inserting and fixing stud bolts 11, and is made of a metal conductor having a thin plate shape.

한편, 탄성고정안내부(30)는 버스바(20)를 스터드볼트(11)에 끼움시 버스바(20)가 탄성력으로 본체(10)에 가거치되도록 안내한다.On the other hand, when the bus bar 20 is inserted into the stud bolt 11, the elastic fixing guide part 30 guides the bus bar 20 to be temporarily placed on the main body 10 with an elastic force.

구체적으로, 탄성고정안내부(30)는 버스바(20)의 안착 위치를 안내하도록 본체(10)에 형성되는 위치안내홈부(31)와, 위치안내홈부(31)의 내측면에 함몰 형성되는 변형공간부(32)와, 변형공간부(32)에 탄성 변형 가능하게 배치되도록 본체(10)에 돌출 형성되어 버스바(20)의 가장자리를 탄성적으로 걸림 지지하는 탄성걸림후크(33)를 포함한다.Specifically, the elastic fixing guide part 30 is a position guide groove 31 formed in the main body 10 to guide the seating position of the bus bar 20, and a position guide groove formed in a depression on the inner surface of the guide part 31 The deformation space portion 32 and the elastic hook 33 protruding from the main body 10 so as to be elastically deformable in the deformation space portion 32 and elastically engaging and supporting the edge of the bus bar 20 include

즉, 탄성걸림후크(33)는 버스바(20)가 위치안내홈부(31)로 진입하는 과정에서 버스바(20)에 접촉되면 변형공간부(32) 측으로 젖혀지다가 버스바(20)가 위치안내홈부(31)에 안착되는 순간 복원되어 버스바(20)의 가장자리를 걸림 지지하여 버스바(20)를 위치 고정시킨다. That is, when the elastic hook 33 contacts the bus bar 20 in the process of the bus bar 20 entering the position guide groove 31, it is bent toward the deformation space part 32 and then the bus bar 20 is positioned. As soon as it is seated in the guide groove 31, it is restored and the edge of the bus bar 20 is caught and supported to fix the position of the bus bar 20.

이에 따라, 버스바(20)는 스터드볼트(11)에 너트(N)를 체결하지 않아도 스터드볼트(11)에 끼워지도록 위치안내홈부(31)에 안착시키면 탄성걸림후크(33)에 걸림 지지되어 본체(10)에 안착된 상태를 유지할 수 있으므로, 조립 작업성을 향상시킬 수 있게 된다.Accordingly, when the bus bar 20 is seated in the position guide groove 31 so as to be inserted into the stud bolt 11 without fastening the nut N to the stud bolt 11, the bus bar 20 is caught and supported by the elastic hook 33. Since it is possible to maintain a seated state on the main body 10, it is possible to improve assembly workability.
