본 발명은 차량용 교류발전기에 관한 것으로, 더욱 상세하게는 계자코일에 전류를 공급하는 슬립링단자와 계자코일인출선을 슬리브에서 용이하게 결합할 수 있도록 한 차량용 교류발전기의 슬리브 구조에 관한 것이다.The present invention relates to a vehicle alternator, and more particularly, to a sleeve structure of a vehicle alternator so that the slip ring terminal for supplying current to the field coil and the field coil lead-in can be easily coupled to the sleeve.

일반적으로 차량용 교류발전기는 엔진의 동력에 의해 회전하면서 전입을 유기하는 것으로, 여러 가지 형태의 것이 다수 제안 사용되고 있는데 그 중 대표적인 것으로 후면브라켓타입과 앤트커버 타입의 교류발전기가 있다. 후면브라켓 타입 교류발전기는 회전축을 지지하는 리어베어링이 회전축의 단부에 설치되어 있기 때문에, 발전기의 전기부품을 수리하기 위해서는 발전기 전체를 차체에서 분리한 후, 리어브라켓을 분해하여야 하는 불편함이 있다. 앤드커버 타입의 교류발전기는 이러한 결점을 보완하기 위해 발전기의 전기부품들을 리어브라켓 외측에 설치하고, 이를 앤드커버가 감싸고 있는 구조인데, 제1도는 일반적인 앤드커버 타입의 교류발전기 내부구성을 보인 정단면도이다.In general, the vehicle alternator rotates by the power of the engine and induces the transfer, and various types are proposed and used. Among them, there are a representative of the rear bracket type and the Ant cover type alternator. In the rear bracket type alternator, the rear bearing supporting the rotating shaft is installed at the end of the rotating shaft. Therefore, in order to repair the electrical parts of the generator, the rear bracket must be disassembled after the whole generator is removed from the vehicle body. The end cover type alternator is a structure in which electrical parts of the generator are installed on the outside of the rear bracket to compensate for this defect, and the end cover is enclosed. FIG. 1 is a front sectional view showing the internal structure of the general end cover type alternator. to be.

차량용 교류발전기는 이에 도시한 바와 같이, 전후방으로 구성되어 외관 몸체를 이루며 공기가 흡입 배기되는 흡입구와 배기구를 갖는 한쌍의 전,후면브라켓(20,20a) 내부에 한쌍의 폴코아로 구성된 회전자(2), 회전자(2)에 축방향으로 압입된 회전축(1)과 이를 회전가능하게 지지하는 베어링(12)이 포함되어 있다. 그리고 전,후면브라켓(20,20a)의 내측면에는 코일(5)이 권선된 고정자(4)가 고정설치되어 있으며, 후면브라켓(20a)의 외측상부와 하부에는 각각 전압조정장치(7)와 브러시(8a)가 내장된 브러시홀더(8) 및 정류기(6) 등이 구성되어 있으며, 이들은 별도의 앤드커버(11)로 감싸져 있다. 또한 회전축(1) 후단부에는 회전자(2)에 권선된 계자코일(3)에 전류를 공급하기 위한 슬립링(9)과 슬리브(30)가 설치되어 있다. 미설명부호 3a는 계자코일(3)에서 인출된 계자코일인출선이고 9a는 회전축(1) 단부 외주면에 마련된 슬립링단자(9a)이다.As shown therein, the alternator for a vehicle is composed of a pair of polcoa inside a pair of front and rear brackets 20 and 20a having an inlet and an exhaust port configured to form an exterior body and intake and exhaust air, as shown in FIG. 2), the rotary shaft 1 is axially pushed into the rotor 2 and a bearing 12 for rotatably supporting it is included. In addition, the inner and outer sides of the front and rear brackets 20 and 20a are fixed with a stator 4 having the coil 5 wound thereon, and the voltage adjusting device 7 and the upper and lower sides of the rear bracket 20a, respectively. The brush holder 8 and the rectifier 6 in which the brush 8a is built are comprised, These are enclosed by the separate end cover 11. A rear end of the rotating shaft 1 is provided with a slip ring 9 and a sleeve 30 for supplying current to the field coil 3 wound on the rotor 2. Reference numeral 3a denotes a field coil lead wire drawn out from the field coil 3, and 9a denotes a slip ring terminal 9a provided on the outer circumferential surface of the end of the rotation shaft 1.

전면브라켓(20)의 외측으로 돌출된 회전(1)의 선단부에는 풀리(50)가 결합되어 있는데, 이것은 밸트(미도시)를 매개로하여 차량의 엔진(미도시)과 연결된다.A pulley 50 is coupled to the front end of the rotation 1 protruding to the outside of the front bracket 20, which is connected to the engine of the vehicle (not shown) through a belt (not shown).

이와 같이 구성된 일반적인 차량용 교류발전기는 엔진(미도시)구동시 폴리(50)가 회전하게 되면, 이와 일체로 결합된 회전축(1)과 회전자(2)가 회전하게 된다. 따라서 계자전류가 형성된 회전자(2)가 전, 후면브라켓(20,20a) 내부에서 고속 회전함에 따라 출력전류가 발생되고, 이 출력전류는 정류기(6)와 전압을 조절하는 전압조정장치(7)를 거쳐 차량의 각 부분에 공급된다.In the general automotive alternator configured as described above, when the poly 50 rotates when the engine (not shown) is driven, the rotating shaft 1 and the rotor 2 which are integrally coupled thereto rotate. Therefore, as the rotor 2 in which the field current is formed rotates at high speed inside the front and rear brackets 20 and 20a, an output current is generated, and the output current is a voltage regulator 7 for regulating the voltage with the rectifier 6. Are supplied to each part of the vehicle.

이러한 기능을 하는 교류발전기의 구성부품 중에서, 종래 슬리브(30)는 제2도의 (a)와 (b)에 도시한 바와 같이, 중심부위에 회전축(1,도1참조)이 관통되도록 축관통공(32)이 형성되어 있으며, 상측과 하측단부에 각각 단자공(31)에 형성되어 있다. 따라서 슬립링단자(9a)의 선단부는 축관통공(32)을 관통한 후 단자공(31)을 통해 상측으로 돌출되게 설치되고, 돌출된 슬립링단자(9a)의 단부에 계자코일인출선(3a)을 감고 납땜수단을 통해 접속시켰다. 즉, 작업자가 슬리브(30)와 베어링(12,도1참조) 사이의 틈새를 통해 슬리브(30) 상측으로 노출된 슬립링단자(9a)와 계자코일인출선(3a)의 단부를 납땜하였다.Among the components of the alternator which perform this function, the conventional sleeve 30 has a shaft through-hole 32 through which a rotating shaft 1 (see Fig. 1) penetrates over a central portion, as shown in FIGS. 2A and 2B. ) Is formed in the terminal hole 31 at the upper and lower ends, respectively. Therefore, the front end of the slip ring terminal 9a is installed to protrude upward through the terminal hole 31 after passing through the shaft through hole 32, and the field coil lead line 3a at the end of the protruding slip ring terminal 9a. ) And connected via soldering means. That is, the operator soldered the ends of the slip ring terminal 9a and the field coil lead-out line 3a exposed to the upper side of the sleeve 30 through the gap between the sleeve 30 and the bearing 12 (see FIG. 1).

그러나, 이러한 단자공(31)을 통해 외부로 돌출된 슬립링단자(9a)와 계자코일인출선(3a)을 납땜하는 과정시 작업자가 상당한 주의를 요하지 않으면, 납용입물이 베어링(12)과 슬리브(30)사이의 공간으로 흘러내려 회전자(2)에 단락현상이 발생되는 경우가 발생된다. 또한 흘러내린 납용입물이 회전축(1)에 고착되는 문제점이 있다.However, if the operator does not need considerable attention in the process of soldering the slip ring terminal 9a and the field coil lead-out line 3a protruding to the outside through the terminal hole 31, the leaded inserts may be separated from the bearing 12. The short circuit phenomenon occurs in the rotor 2 by flowing into the space between the sleeves 30. In addition, there is a problem that the lead filler flowed down is fixed to the rotating shaft (1).

본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 회전축의 일단부에 끼워져 결합되며 계자코일인출선과 슬립링단자가 접속되는 슬리브에 연결단자와 안내홈을 구성함으로써, 연결단자를 매개로하여 계자코일인출선과 슬립링단자의 접속을 용이하게 하는 차량용 교류발전기를 제공하는 것이다. 이러한 목적을 달성하기 위한 본 발명은, 외관을 이루는 전면브라켓과 후면 브라켓, 전,후면 브라켓의 내주부에 고정설치되는 고정자, 고정자의 중심부에 축방향으로 설치되며 계자코일이 권선된 회전자, 회전자의 중심부에 축방향으로 압입되어 일체로 회전되는 회전축, 후면브라켓을 관통하여 외부로 노출되는 회전축의 단부를 회전가능하게 지지하는 베어링, 후면브라켓 외부로 노출된 회전축 단부 외주면에 마련된 슬립링과 슬립링단자, 선단부가 슬립링과 마찰하여 전기적으로 접속되도록 브러시가 내장된 브러시홀더, 브러시홀더를 감싸도록 후면브라켓에 결합되는 앤드커버, 베어링과 회전자 사이의 회전축 단부에 끼워져 결합되며 슬립링단자와 계자코일에서 인출된 계자코일인출선의 접속을 안내하는 슬리브를 갖춘 차량용 교류발전기에 있어서, 슬리브의 외주부에는 슬립링단자의 단부와 계자코일인출선이 납땜수단을 통해 접속이 용이하도록 한쌍의 연결단자가 대응되게 돌출돠어 있으며, 슬립링단자를 연결단자에 접속되도록 안내하는 오목하게 패인 안내홈이 마련되는 것을 특징으로 한다.The present invention is to solve this problem, an object of the present invention is to be fitted to one end of the rotary shaft coupled to form a connecting terminal and a guide groove in the sleeve that is connected to the field coil lead wire and the slip ring terminal, through the connecting terminal The present invention provides an alternator for a vehicle that facilitates connection between a field coil lead wire and a slip ring terminal.

먼저, 회전축(1) 후단부에 슬리브(40)를 압입 고정하고, 슬립형(9)을 후면브라켓(20a,제1도참조) 외측으로 돌출되는 회전축(1) 후단부에 설치한다. 그리고 슬립링(9)에서 인출된 소정길이의 슬립링단자(9a)를 슬리브(40) 상,하측에 형성된 안내홈(42,42a)에 각각 삽입한다. 이 때, 안내홈(42,42a)에는 돌기(43,43a)가 교호적으로 돌출되어 있어 슬립링단자(9a)는 억지끼움되며 인위적인 힘을 가하지 않고서는 이탈되지 않는다. 계속하여 안내홈(42,42a)에 삽입 고정된 슬립링단자(9a)의 단부를 연결단자(41,41a)에 끼우고, 계자코일(3)에서 인출된 계자코일인출선(3a)을 역시 연결단자(41,41a)에 다수번 감아서 납땜수단을 통해 고정하면, 제4도에 도시한 바와 같이 슬립링단자(9a)와 계자코일인출선(3a)이 전기적으로 접속된다. 따라서 슬립링단자(9a)와 계자코일인출선(3a)이 연결단자(41,41a)를 매개로하여 용이하게 접속 고정되며, 납용입물이 흘러내리지 않게 된다.First, the sleeve 40 is press-fitted to the rear end of the rotating shaft 1, and the slip type 9 is installed at the rear end of the rotating shaft 1 protruding to the outside of the rear bracket 20a (see FIG. 1). Then, the slip ring terminal 9a of the predetermined length drawn out from the slip ring 9 is inserted into the guide grooves 42 and 42a formed above and below the sleeve 40, respectively. At this time, the projections 43 and 43a are alternately protruded from the guide grooves 42 and 42a so that the slip ring terminal 9a is clamped and cannot be released without applying an artificial force. Subsequently, the end of the slip ring terminal 9a inserted into the guide grooves 42 and 42a is inserted into the connecting terminals 41 and 41a, and the field coil lead-out line 3a drawn out from the field coil 3 is also inserted. When wound several times on the connecting terminals 41 and 41a and fixed by soldering means, as shown in FIG. 4, the slip ring terminal 9a and the field coil lead wire 3a are electrically connected. Therefore, the slip ring terminal 9a and the field coil lead-out line 3a are easily connected and fixed through the connecting terminals 41 and 41a, and the leaded filler material does not flow down.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 차량용 교류발전기는 회전축의 일단부에 끼워져 결합되며 계자코일인출선과 슬립링단자가 접속되는 슬리브에 연결단자와 안내홈을 구성하였다. 따라서 계자코일인출선과 슬립링단자의 접속이 연결단자를 매개로하여 용이하게 되며, 접속과정시 납용입물이 흘러내리지 않아 회전축에 고착되는 현상이 발생되지 않는다.As described in detail above, the vehicle alternator according to the present invention is coupled to one end of the rotary shaft and constituted a connecting terminal and a guide groove in a sleeve to which the field coil lead wire and the slip ring terminal are connected. Therefore, the connection between the field coil lead wire and the slip ring terminal is facilitated through the connecting terminal, and the solder filler does not flow down during the connection process, so that the phenomenon of fixing to the rotating shaft does not occur.
