본 발명은 차량용 정션박스의 버스바 고정 구조에 관한 것이다The present invention relates to a bus bar fixing structure of a junction box for a vehicle.

차량에 설치되는 정션박스의 주요 내부 구조는, 여러 개의 버스바와 그 버스바를 고정 및 절연하는 절연판이 하나의 조립체로 이루어지며, 이러한 조립체들이 여러층으로 적층되어 하나의 정션 박스 내부 구조를 이루고 있다The main internal structure of the junction box installed in the vehicle is composed of a single assembly of several busbars and an insulating plate for fixing and insulating the busbars, and these assemblies are stacked in multiple layers to form a single junction box internal structure.

종래에는 도금 강판으로 이루어지는 버스바를 절연판에 고정할때, 버스바의 소정의 부위에 절곡된 핀을 형성하고 이 절곡된 핀이 절연판을 관통하여 나오고, 그 절연판을 관통하여 나온 배면을 일일이 용접 작업하여 왔다Conventionally, when fixing a bus bar made of a plated steel sheet to an insulating plate, a bent pin is formed at a predetermined portion of the bus bar, and the bent pin is penetrated through the insulating plate, and the back surface penetrating through the insulating plate is welded individually. come

이 경우, 매우 많은 양의 버스바를 일일이 용접 고정 잡업하는 일은 매우 큰 시간 손실을 초래할 뿐만 아니라, 그 용접작업이 매우 번거롭고 별도의 용접을 위한 재료가 투입되어 결국 생산성이 떨어지고 제조원가 상승의 원인이 되어 왔다. In this case, the welding fixed operation of a very large amount of busbars not only causes a great loss of time, but also the welding work is very cumbersome and a separate welding material is added, which leads to a decrease in productivity and a rise in manufacturing cost. .

본 발명은 상기한 점을 감안하여 발명한 것으로, 별도의 그 수많은 용접 작업 없이 압입에 의해 간단히 고정되는 버스바의 구조를 제공함에 본 발명의 목적이 있다. SUMMARY OF THE INVENTION The present invention has been made in view of the above point, and an object of the present invention is to provide a structure of a bus bar which is simply fixed by indentation without a large number of separate welding operations.

상기한 본 발명의 목적을 달성하기 위한 본 발명의 주요 구성은, 평판상의 버스바(2)에 "ㄱ" 자로 절곡된 형상의 고정핀(3)을 형성한 것을 특징으로 하며, 상기한 고정핀(3)은 그 절곡된 단부가 원형상의 곡부(5)를 형성하며, 그 곡부(5)의 좌우측은 경사부(4)를 형성한 것을 특징으로 하며, 상기한 고정핀(3)의 절곡 각도는 측면에서 볼때, 90도 내지 110도로 벌어진 둔각으로 형성되는 것을 특징으로 한다The main configuration of the present invention for achieving the above object of the present invention, characterized in that the fixing pin (3) of the shape bent in the "b" shape on the flat bus bar (2), said fixing pin (3) is characterized in that the bent end forms a circular curved portion 5, the left and right sides of the curved portion 5 is formed with an inclined portion (4), the bending angle of the fixing pin (3) When viewed from the side, it characterized in that formed at an obtuse angle that is 90 degrees to 110 degrees

상기한 특징 외의 다른 특징 및 구성에 대하여 이하, 첨부 도면에 의거 추가로 상술한다Other features and configurations other than those described above will be further described below based on the accompanying drawings.

도 1 은 본 발명에 따라 절연판(1)에 버스바(2)가 고정되어 있는 것을 예시하는 도면이다1 is a diagram illustrating that the bus bar 2 is fixed to the insulating plate 1 according to the present invention.

도시한 바와 같이, 절연판의 표면에 형성된 일정형사의 홈에 플레이트 형상으로 이루어진 여러가지 형태의 버스바(2)가 고정되어 있다. 각각의 버스바(2)는 소정의 부위에 절곡된 형상의 고정핀(3)을 형성하여 절연판(1)를 관통하여 고정되 어 있다As shown in the figure, the bus bars 2 of various shapes having a plate shape are fixed to grooves of a constant shape formed on the surface of the insulating plate. Each bus bar 2 is fixed to penetrate the insulating plate 1 by forming a fixing pin 3 of a bent shape in a predetermined portion.

도 2 는 이를 뒤집어 놓은 형상을 도시한다2 shows the shape upside down.

도시한 바와 같이, 복수의 고정핀(3) 단부가 절연판(1)의 배면에 약간 돌출되어 나와 있음을 확인할 수 있다As shown, it can be seen that the end of the plurality of fixing pins 3 slightly protrude out the back of the insulating plate (1).

도 3 은 버스바(2)를 절연판(1)에서 분리하여 도시한 것이다3 shows the busbar 2 separated from the insulating plate 1.

도시한 바와 같이, 하나의 버스바(2)를 고정하기 위하여 절곡된 형상의 여러개의 고정핀(3)이 구성된다As shown, a plurality of fixing pins 3 of a bent shape are configured to fix one bus bar 2.

도 4 는 고정핀(3)의 상세 사시도이다.4 is a detailed perspective view of the fixing pin 3.

고정핀(3)의 단부는 그 좌우가 좁아지는 경사부(4)를 이루고 가장 끝단은 곡부(5)로 구성된다. 이렇게 형성하는 이유는 절연판(1)에 형성된 통공에 끼울때 그 삽입이 용이하게 되게 하기 위한 것이다The end of the fixing pin (3) forms an inclined portion (4) narrowing the left and right, the most end is composed of a curved portion (5). The reason for forming this is to facilitate insertion when inserted into the through hole formed in the insulating plate (1).

도 5 는 도 4 를 정면에서 본 단면으로 고정핀(3)의 절곡된 부분이 90도 직각이 아니라 "a" 각도(10∼20도) 정도 더 벌어진 둔각으로 이루어진다FIG. 5 is a cross-sectional view of FIG. 4 in which the bent portion of the fixing pin 3 is formed at an obtuse angle wider by an "a" angle (10 to 20 degrees) rather than a right angle of 90 degrees.

직각으로 만들지 않고 이렇게 둔각으로 만드는 이유는 고정핀(3)을 절연판(1)에 형성된 통공에 끼워 넣을때 약간의 힘을 가하여야 끼워 질 수 있게 하기 위한 것이며, 일단 한번 힘을 주고 끼우면 쉽게 이탈되지 않게 하기 위한 것이다The reason for making this obtuse rather than making it at right angles is to allow the pin to be inserted with a slight force when inserting the fixing pin (3) into the through hole formed in the insulating plate (1). It is to prevent

상기한 구성에 의한 버스바의 결합 작업은, 버스바(2)를 일정한 위치에 정돈한 상태로 위치하여 두고, 절연판(1)과 예를들어 프레스에 의해 가압에 의하여 결합시키면 하나의 절연판에 모든 버스바(2)가 한번에 고정된다Coupling operation of the bus bar by the above-described configuration is carried out by placing the bus bar 2 in a fixed position in a fixed position, and combining the insulating bar 1 with pressure by, for example, pressing. Busbar 2 is fixed at once

이상과 같은 본 발명에 의하면, 하나의 절연판에 많은 버스바의 고정 작업이 매우 빠른 시간에 신속하게 이루어지므로 생산성을 매우 크게 혁신적으로 높일 수 있다. 본 발명은 비록 그 고정 구조는 간단하다 할수도 있겠지만 그 생산성의 효과는 매우 지대하다According to the present invention as described above, since the fixing work of many busbars on one insulating plate is performed quickly in a very fast time, the productivity can be greatly innovatively increased. In the present invention, although the fixing structure is simple, the effect of productivity is enormous.
