Description

자동차용 발전기의 터미널{TERMINAL OF ALTERNATOR FOR CAR}Terminal of generator for automobiles {TERMINAL OF ALTERNATOR FOR CAR}

본 발명은 자동차용 발전기의 터미널에 관한 것으로, 특히 터미널의 조립시터미널이 리어브라켓의 원주방향으로 돌출되게 설치됨으로써 조립공간이 많이 차지하지 않을 뿐 아니라, 발전기에서 차량으로의 전기공급을 안정적으로 할 수 있도록 한 자동차용 발전기의 터미널에 관한 것이다.The present invention relates to a terminal of an automobile generator, and in particular, the terminal assembly terminal is protruded in the circumferential direction of the rear bracket, so that not only does not occupy a lot of assembly space, but also stable supply of electricity from the generator to the vehicle. It relates to the terminal of a car generator.

종래의 발전기는 도 3 및 도 4에 나타낸 바와 같이, 발전기의 축 회전을 위하여 설치되는 베어링을 지지하고 있는 하우징(1)내에 정류기를 배치하고 이 정류기에는 히트싱크(2)와 보드(4) 및 플레이트(6)가 밀착설치되며, 상기 히트싱크(2)에 끼워진 절연체(8)를 매개로 축방향 출력 터미널부재(3)가 상기 리어브라켓(1)의 측방향으로 돌출되게 설치되고, 소정형상의 절연층부재 (10)로 감싸여진 방사상 출력 터미널부재(11)가 상기 축방향 출력 터미널부재(3)에 전기적으로 연결되도록 너트(9)로 체결하여 구성되어 있었다.Conventional generators, as shown in Figures 3 and 4, the rectifier is arranged in a housing (1) supporting a bearing installed for the shaft rotation of the generator, which has a heat sink (2) and a board (4) and The plate 6 is installed in close contact, and the axial output terminal member 3 is installed to protrude laterally of the rear bracket 1 via the insulator 8 fitted to the heat sink 2, and has a predetermined shape. The radial output terminal member 11 wrapped by the insulating layer member 10 was formed by fastening with a nut 9 so as to be electrically connected to the axial output terminal member 3.

상기와 같은 종래의 것은 상기 절연층부재(10)에 의해 감싸여진 방사상 출력 터미널부재(11)의 내측단부(11a)가 상기 축방향 출력 터미널부재(3)에 끼워진 상태로 너트(9)에 의해 체결됨과 더불어, 상기 방사상 출력 터미널부재(11)의 내측단부(11a)를 감싸면서 원형돌기(10a)의 개구부(10a)로 너트(9)가 체결된 상태로 원형돌기(10a)를 감싸도록 캡(12)이 끼워져 있었으며, 상기 방사상 출력 터미널부재(11)의 시트(11b)에서 상부로 숫나사부(11c)가 돌출되게 설치되어 있었다.The conventional method as described above is provided by the nut 9 with the inner end 11a of the radial output terminal member 11 wrapped by the insulating layer member 10 fitted to the axial output terminal member 3. In addition to being fastened, the cap surrounds the inner end portion 11a of the radial output terminal member 11 and surrounds the circular protrusion 10a while the nut 9 is fastened to the opening 10a of the circular protrusion 10a. (12) was fitted, and the male screw part 11c protruded from the sheet | seat 11b of the said radial output terminal member 11 to the upper part.

따라서 상기 방사상 출력 터미널부재(11)의 숫나사부(11c)로 전원이 공급되어 축방향 출력 터미널부재(3)를 통해 내부에 공급될 때, 상기 절연층부재(10)와 절연체(8)에 의해 절연되어 리어브라켓(1)과 쇼트가 일어나지 않게 되어 있었다.Therefore, when power is supplied to the male screw portion 11c of the radial output terminal member 11 and supplied to the inside through the axial output terminal member 3, the insulating layer member 10 and the insulator 8 It was insulated and the rear bracket 1 and the short did not arise.

그러나, 상기와 같은 종래의 것은 히트싱크와 연결된 축방향 출력 터미널부재와 하우징 외측의 방사상 출력단자가 연결되도록 되어 있지만, 이 연결부위가 하우징으로 인하여 히트싱크와 분리되는 상태가 되어 발전기의 발전량이 높을 경우 축방향 터미널부재가 발열하게 되는 폐단이 있었고, 상기 발열에 의하여 상기 연결부위의 연결상태가 불량하게 되는 결점이 있었으며, 상기 연결부위가 작기 때문에 차량의 운행도중 진동이나 충격에 의하여 상기 연결상태가 이완되는 폐단이 있었고, 상기 이완에 따라 밧데리의 충전상태가 불량하게 되면서 연결부위에서 스파크가 발생되며, 이에 따라 화재가 발생될 염려가 있는 등의 문제점이 있었다.However, in the conventional art as described above, although the axial output terminal member connected to the heat sink and the radial output terminal outside the housing are connected to each other, the connection part is separated from the heat sink due to the housing, so that the generation amount of the generator is high. There was a closed end where the axial terminal member generates heat, and there was a defect that the connection state of the connection part was poor due to the heat generation, and the connection state was loosened by vibration or shock during driving of the vehicle because the connection part was small. There was a closed end, and as the state of charge of the battery becomes poor, the spark is generated at the connection part, and thus there is a problem such that a fire may occur.

본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 리어브라켓의 측방에서 축방향과 수직으로 직선형상의 방사상 출력 터미널이 절연부재에 의해 감싸인 상태로 히트싱크와 직접 접촉되고 고정됨으로써, 터미널의 조립시 터미널이 리어브라켓의 원주방향으로 돌출되게 설치됨으로써 조립공간이 많이 차지하지 않을 뿐 아니라, 히트싱크와의 접촉면적을 증대시킬 수 있게 되며 이에 따라 접촉면적의 축소로 인한 발열과 접촉불량이 발생되지 않도록 하고 안정적인 전류를 차량의 전기장치에 공급할 수 있도록 하는 자동차용 발전기의 터미널을 제공함에 그 목적이 있다.The present invention has been made in order to solve the above problems, the linear radial output terminal in the axial direction perpendicular to the side of the rear bracket is directly contacted and fixed to the heat sink in a state surrounded by an insulating member, When assembling, the terminal protrudes in the circumferential direction of the rear bracket, which not only takes up a lot of assembly space, but also increases the contact area with the heat sink, resulting in heat generation and poor contact due to the reduction of the contact area. The purpose of this invention is to provide a terminal for an automobile generator that can prevent the supply of electricity to a vehicle's electric device.

여기서 상기 방사상 출력 터미널(400)은, 상기 고정볼트(600)로 고정되는 부분은 접촉부(410)와, 이 접촉부(410)에서 연장되어 상기 절연부재(500)의 커넥터연결부(510)에 일정깊이 감싸여진 원형돌기(420)와, 이 원형돌기(420)의 축중심에서 외부로 일정길이 원주형의 단자부(430)로 이루어져 있다.Wherein the radial output terminal 400, a portion fixed to the fixing bolt 600 is a contact portion 410, and extends from the contact portion 410 to a predetermined depth in the connector connection portion 510 of the insulating member 500 The circular protrusion 420 is enclosed, and the terminal portion 430 of a predetermined length is formed from the axis center of the circular protrusion 420 to the outside.

미설명부호 800은 상기 축(300)과 동기회동되도록 설치된 회전자이고, 900은 고정자이다.Reference numeral 800 is a rotor installed to be synchronized with the shaft 300, 900 is a stator.

따라서 상기 히트싱크(700)로부터 방사상 출력 터미널의 단자부로 전류가 공급될 때 상기 절연부재(500)에 의해 상기 하우징(200)과 쇼트되지 않으면서 전원이 공급되게 된다.Accordingly, when current is supplied from the heat sink 700 to the terminal portion of the radial output terminal, power is supplied without being shorted with the housing 200 by the insulating member 500.

또한 상기 방사상 출력 터미널(400)의 접촉부(410)와 원형돌기(420) 및 단자부(430)의 축방향이 일직선상에 있으므로 하우징(200)의 후방으로 많은 조립공간이 필요하지 않게 된다.In addition, since the axial direction of the contact portion 410 and the circular protrusion 420 and the terminal portion 430 of the radial output terminal 400 is in a straight line, there is no need for a large assembly space behind the housing 200.

상기와 같이 설명한 본 발명의 의하면, 터미널의 조립시 터미널이 하우징의 원주방향으로 돌출되게 설치됨으로써 조립공간이 많이 차지하지 않을 뿐 아니라, 터미널의 접촉부와 원형돌기 및 단자부의 축방향이 일직선상에 있으므로 제조도 용이하게 되는 효과가 있다.According to the present invention as described above, since the terminal is installed to protrude in the circumferential direction of the housing during assembly of the terminal, not only does not occupy much assembly space, but also because the axial direction of the contact portion, the circular protrusion and the terminal portion of the terminal is in a straight line It also has the effect of being easy to manufacture.

Accordingly, the heat dissipation can be effectively performed, and the heat dissipation effect can be improved so that the relaxation action at the contact part does not occur, and the contact state of the contact part is maintained even if vibration or shock is generated while driving the vehicle according to the increase of the contact area. It is not relaxed, and the current generated from the generator is reliably supplied and charged to the vehicle and the battery.
