본 고안은 자동차용 시동모우터의 전자스위치에 관한 것으로, 특히 시동모우터의 전자스위치 구성부품인 보빈과 부시를 일체형으로 구성하므로서 전자스위치의 코일에서 발생하는 지속의 누설을 방비하여 성능을 향상시키도록 할 뿐 아니라 조립공정의 단순화를 통한 원가절감 효과를 갖도록 한 것이다.The present invention relates to an electronic switch of a starter motor for automobiles. In particular, the bobbin and the bush, which are the electronic switch components of the starter motor, are integrally formed to prevent performance leakage and improve performance. In addition to reducing the cost, the assembly process is simplified.

시동모우터는 자동차의 엔진이 자력으로 시동될 수 없기 때문에 초기에 엔진의 크랭크샤프트를 일시적으로 회전시켜 엔진을 시동하는데 사용되는 것으로, 제1도는 종래 자동차용 시동모우터의 종단면 구성도이고, 제2도는 제1도의 좌측면도이며, 제3도는 회로도이다.The starting motor is used to start the engine by temporarily rotating the crankshaft of the engine initially because the engine of the automobile cannot be started by magnetic force. Fig. 1 is a left side view of Fig. 1, and Fig. 3 is a circuit diagram.

프린저(6)가 흡입되어 코아스위치(7)의 콘트롤로드(8)에 닿으므로서 시프트레버(9)가 동력전달부(2)의 피니언을 밀어내게 되고, 또한, 콘택트로드(8)가 단자 "B"와 단자 "M"에 붙으므로 축전지단자로부터 대전류가 단자 "B"와 단자 "M"을 통해 전동기부(1)로 공급되어 전동기부(1)가 작동된다.As the fringer 6 is sucked in and touches the control rod 8 of the core switch 7, the shift lever 9 pushes out the pinion of the power transmission unit 2, and the contact rod 8 Since it is attached to the terminal "B" and the terminal "M", a large current is supplied from the battery terminal to the motor unit 1 through the terminal "B" and the terminal "M", and the motor unit 1 is operated.

따라서 상기 전동기부(1)가 작동되므로서 발생되는 회전력이 동력전달부(2)를 통해 엔진에 전달되어 자동차가 시동되는 것이었다.Therefore, the rotational force generated by the operation of the electric motor unit 1 is transmitted to the engine through the power transmission unit 2 to start the car.

그런데 이러한 시동모우터의 전자스위치(3)는 코일(5)이 일정한 권취수로 감겨진 보빈(4)내에 코아스위치(7)가 구비됨과 동시에 진퇴작동되는 플런저(6)가 구비되므로서 이들 사이에는 필수적으로 부시가 구비되어야만 하는 것이었다.By the way, the electronic switch 3 of the starting motor is provided with a core switch 7 in the bobbin 4 in which the coil 5 is wound with a constant number of windings, and a plunger 6 for advancing and retracting operation is provided therebetween. Was essentially a bush to be provided.

그러나 종래에는 상기한 보빈과 부시를 각각 별도의 제품으로 제작하여 도시된 바와같이 이는 일반적으로 전원을 공급받아 회전력을 발생시키는 전동기부(1)와, 상기 전동기부(1)의 회전력을 감속시켜 엔진의 링기어를 구동시키는 동력전달부(2)와, 그리고 상기 동력전달부(2)로부터 전달되는 회전력으로 엔진의 링기어를 구동시킬 수 있도록 동력전달부(2)의 전달동력을 링기어에 물리게 하는 전자스위치(3)로 구성되어 있다.However, in the related art, the bobbin and the bush are manufactured as separate products, respectively, and as shown in the drawing, this generally reduces the rotational force of the motor unit 1 and the motor unit 1 to generate a rotational force by receiving power. The transmission power of the power transmission unit 2 for driving the ring gear of the engine and the transmission power of the power transmission unit 2 so as to drive the ring gear of the engine by the rotational force transmitted from the power transmission unit 2. Is composed of an electronic switch (3).

이러한 시동모우터에 있어 전자스위치(3)는 축전지에서 기동전동기로 흐르는 큰전류를 단속하는 작용과 더불어 동력전달부의 피니언과 엔진의 링기어를 물리게 하는 작용을 하는 것으로서 이는 스위치를 ON하면 전류가 단자 "S"를 통해 보빈(4)에 감겨진 코일(5)에 흘러 주위에 자속이 발생되고, 이 자속에 의해 보빈(4)내에 구비되는 보빈의 부시를 억지 끼움하는 식으로 조립구성 하는 것으로서, 이는 몇가지 문제점을 안고 있는 것이었다.In such a starting motor, the electronic switch 3 acts to interrupt a large current flowing from the battery to the starting motor and to bite the pinion of the power transmission unit and the ring gear of the engine. The magnetic flux is generated around the coil 5 wound around the bobbin 4 through " S ", and the assembly of the bobbin of the bobbin provided in the bobbin 4 by the magnetic flux is assembled. This had some problems.

즉 장기간의 사용에 의한 보빈의 내경과 부시와의 사이에는 틈새가 발생하게 되고, 이로 인해 이의 틈새를 통하여 내부의 자속이 누설되므로서 전자스위치의 성능이 저하되는 문제점이 있는 것이었고, 이러한 문제점은 심할 경우 부시가 진동되어 발생되는 것이었으며 또한 보빈과 부시를 억지끼움식으로 조립하여야 하므로서 조립작업이 어려워 작업성이 저하되는 문제점도 있는 것이었다.That is, a gap is generated between the inner diameter of the bobbin and the bush due to long-term use, which causes the internal magnetic flux to leak through the gap, thereby degrading the performance of the electronic switch. If the severe was caused by the vibration of the bush and also because the bobbin and the bush must be assembled by interference type, the assembly work is difficult, there is also a problem that the workability is reduced.

본 고안은 상기와 같은 사정을 고려하여 이루어진 것으로 그 목적은 전자스위치의 보빈과 부시를 일체형으로 사출성형하여 기밀성을 향상시켜 자속의 누설을 방지토록 함과 동시에 조립의 단순화로 작업성을 향상시킨 자동차용 시동모우터의 전자스위치를 제공함에 있다.The present invention has been made in consideration of the above circumstances, and its purpose is to integrally injection-mold bobbin and bush of electronic switch to improve airtightness to prevent leakage of magnetic flux and at the same time to improve workability by simplifying assembly. The invention provides an electronic switch for a starting motor.

계속해서 본 고안의 바람직한 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Subsequently, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도면의 제3도는 본 고안의 적용한 시동모우터의 전자스위치를 보인 구성도로서 3은 전자스위치의 본체이다. 이의 본체(3)는 케이스(10)내에 구비되고 코일(5)이 일정한 권취수로 감겨진 합성수지 재질의 보빈(4)과, 상기 보빈(4)내의 일측에 구비되고 콘텍트로드(8)를 갖는 코아스위치(7)와, 상기 코아스위치(7)와 대향되게 구비되고 끝단부에 시프트레버(9)를 구비한 플런저(6)와, 그리고 상기 보빈(4)의 내경에 구비되고 코아스위치(7)및 플런저(6)의 작동을 원활히 하도록 하는 금속재질의 부시(11)로 구성된다.3 is a block diagram showing an electronic switch of the starting motor to which the present invention is applied, and 3 is a main body of the electronic switch. Its main body 3 is provided in the case 10 and the coil 5 is a synthetic resin bobbin (4) wound around a constant winding water, and provided on one side in the bobbin 4 and having a contact rod (8) A core switch 7, a plunger 6 provided opposite to the core switch 7 and having a shift lever 9 at an end thereof, and an inner diameter of the bobbin 4 and provided in the core switch 7. And it is composed of a metal bush 11 to facilitate the operation of the plunger (6).

이는 종래와 동일한 구성을 가지며 다만 본 고안은 코일(5)이 감겨지는 보빈(4)과, 상기 보빈(4)의 내경에 구비되는 부시(11)를 일체형으로 사출성형 하여서 된 것이다.This has the same configuration as the conventional one, but the present invention is made by injection molding the bobbin 4, the coil 5 is wound, and the bush 11 provided in the inner diameter of the bobbin 4 in one piece.

즉, 금속재질의 부시(11)를 먼저 성형한 다음 이의 외경으로 합성수지 재질의 보빈(4)을 사출성형하므로서 보빈(4)의 내경과 부시(11)의 외경면이 완전히 접착고정되어 일체형으로 구성되는 것이다.That is, the bush 11 of the metal material is first formed and then the injection molding of the bobbin 4 made of a synthetic resin material with the outer diameter thereof makes the inner diameter of the bobbin 4 and the outer diameter surface of the bush 11 completely bonded and fixed to constitute an integral type. Will be.

따라서, 이와같은 본 고안은 전자스위치를 ON시키면 전류는 코일(5)에 흘러 주위에 자속을 발생시크므로서 이의 자속에 의해 보빈(4)내에 구비된 플런저(6)가 진퇴 작동되어 전술한 바와같이 샤프트레버(9)가 동력전달부(2)의 피니언을 작동시킴과 동시에 전동기부(1)를 작동시켜 시동이 이루어지게 되는 것이다.Therefore, in the present invention, when the electronic switch is turned on, current flows in the coil 5 to generate magnetic flux around, so that the plunger 6 provided in the bobbin 4 is moved forward and backward by the magnetic flux thereof, as described above. The shaft lever 9 operates the pinion of the power transmission unit 2 and at the same time operates the electric motor unit 1 to start.

이때, 상기와 같이 진퇴작동되는 플런저(6)는 보빈(4)에 일체형으로 구비된 부시(11)의 내경을 따라 슬라이드되면서 진퇴작동되지만 보빈(4)과 부시(11)가 완전히 밀착고정되어 있으므로서 진동없이 정확한 진퇴작동이 되는 것이다.At this time, the plunger 6, which is moved forward and backward as described above, slides along the inner diameter of the bush 11 that is integrally provided on the bobbin 4, but the bobbin 4 and the bush 11 are completely tightly fixed. In this way, accurate retraction operation is performed without vibration.

즉, 보빈(4)과 부시(11)가 일체형으로 구비되므로서 이들 사이에 틈새가 발생되지 않아 부시(11)의 유동이 발생치 않는 것이고, 이에 따라 진퇴작동되는 플런저(6)도 진동없이 작동되는 효과를 가지게 되는 것이다.That is, since the bobbin 4 and the bush 11 are integrally formed, no gap is generated between them so that the flow of the bush 11 does not occur. Accordingly, the plunger 6, which is moved back and forth, also operates without vibration. Will have the effect.

또한, 종래와 같이 보빈과 부시사이의 미세한 틈새를 통해 누설되면 자속과 이를 통해 유입되면 이물질을 막을 수 있게 됨에 따라 전자스위치내의 내구성이 향상될 뿐 아니라 성능이 그만큼 향상되는 효과를 가지게 되는 것이고, 더불어 조립공정이 필요없게 되므로서 작업성이 향상되는 효과도 가지게 되는 것이다.In addition, when leaking through the minute gap between the bobbin and the bush as in the prior art to prevent the magnetic flux and foreign matter flowing through it as well as to increase the durability in the electronic switch as well as to have the effect of improving the performance. Since no assembly process is required, workability is also improved.
