본 고안은 정류자형 전동기에 설치되는 브러쉬 지지장치에 관한 것으로서, 특히 전원선 터미널을 이용하여 브러쉬의 스프링받이를 고정시킴과 동시에 전기적 접촉을 꾀한 브러쉬 지지장치의 개량고안이다.The present invention relates to a brush support device installed in the commutator-type electric motor, and is an improved design of the brush support device intended for the electrical contact at the same time while fixing the spring receiving of the brush using a power line terminal.

종래의 브러쉬 지지장치는 제 1 도와 같이, 브러쉬 홀더(1)내에 브러쉬(2) 및 이 브러쉬(2) 후면에서 인출된 리드(3)와 연결됨과 동시에 이 리드(3)주위로 스프링(4)이 끼워진 스프링받이(5)가 함께 삽입되어, 상기 슬프링받이(5)가 브러쉬 홀더(1)에 핀(6)으로 고정되며 외부전선(7)이 상기 브러쉬 홀더(1)의 접속단자(8)에 납땜되는 구성으로 되어 있다.The conventional brush support device is connected to the brush 2 in the brush holder 1 and to the lead 3 drawn out from the rear of the brush 2, as in the first diagram, and at the same time the spring 4 around the lead 3. The fitted spring bearing 5 is inserted together so that the spring holder 5 is fixed to the brush holder 1 with the pin 6 and the outer wire 7 is connected to the brush holder 1 with the terminal 8. ) Is soldered to the structure.

이와 같은 종래의 구성에서는 브러쉬(2)의 스프링(4)을 지지하는 스프링받이(5)가 단지 가는 핀(6)으로 지지된 것이므로 스프링의 지지상태가 불안정하여 브러쉬(2)의 압력이 일정치 않고 또한 전선(7)을 연결하는 작업에도 번거로운 문제점이 있었다.In this conventional configuration, since the spring holder 5 supporting the spring 4 of the brush 2 is supported by only a fine pin 6, the support state of the spring is unstable and the pressure of the brush 2 is constant. Also, there was a troublesome problem in connecting the wires 7.

본 고안의 목적은 이와 같은 종래의 문제점을 해결하기 위하여 브러쉬의 스프링받이를 직접 고정시키고 동시에 전선을 연결시키는 전선터미널을 사용하여 스프링의 지지상태가 안정되고 작업성이 좋은 브러쉬 지지장치를 제공하려는 것이다.The purpose of the present invention is to provide a brush support device that is stable and workable by using a wire terminal to directly fix the spring receiving of the brush and at the same time to connect the wire in order to solve such a conventional problem. .

상기 목적을 달성하기 위하여 본 고안에서는 브러쉬 홀더의 후단부 상하면에 직사각 구멍을 뚫어 전선이 직접 압착연결되는 터미널이 끼워지게 하되 동시에 상기 직사각 구멍 내측에 걸리도록 하는 탄성 고정편을 형성하여 하나의 터미널로써 브러쉬를 지지시킴과 동시에 전선의 접속을 꾀하고 있는 점이 특징이다.In order to achieve the above object, the present invention drills a rectangular hole on the upper and lower surfaces of the rear end of the brush holder to allow the wire to be directly crimped to be connected to the terminal, and at the same time, forms an elastic fixing piece to be caught inside the rectangular hole as a terminal It is characterized by supporting brushes and connecting wires.

상기 특징에 따라 구성된 본 고안의 바람직한 실시예를 첨부된 도면에 의거하여 상세하게 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings a preferred embodiment of the present invention configured in accordance with the above features as follows.

본 고안 실시예의 구성은 제 2 도와 같이 모터본체(21)에 부도체인 브라켓(22)을 의지하여 도체인 브러쉬 홀더(23)가 고정 설치되고, 브러쉬 홀더(23)내에는 탄소막대의 브러쉬(24)와, 그 후면에서 인출된 리드(25)단부와 연결되고 동시에 그 리드(25)주위로 끼워진 스프링(26)을 받쳐 주는 스프링받이(27)가 차례로 삽입되는 한편, 상기 브러쉬 홀더(23) 후단부의 상하면에는 직사각 구멍(28)(28')이 상호 일치되게 뚫려 이에 터미널(29)이 끼워지되 터미널(29)의 중앙부에는 그 일부가 블랭킹(blanking)되어 절곡된 탄성고정편(30)이 형성되어 상기 직사각 구멍(28 또는 28') 내측에 걸려 고정되고, 이와 동시에 터미널(29) 이면으로는 상기 스프링받이(27)가 접촉 지지되며, 그리고 상기 터미널(29) 하단부에는 전선 압착편(31)이 형성되 이에 전선(32)이 압착연결되는 구성이다.The configuration of the embodiment of the present invention, as shown in the second diagram, the brush holder 23, which is a conductor, is fixed to the motor body 21 by the bracket 22, which is a non-conductor, and the brush 24 of the carbon rod is provided in the brush holder 23. ) And a spring receiver 27 connected to the end of the lead 25 drawn from the rear thereof and simultaneously supporting the spring 26 inserted around the lead 25 are inserted in turn, while the rear end of the brush holder 23 is inserted. Rectangular holes 28 and 28 'are drilled to coincide with each other on the upper and lower sides thereof, and the terminal 29 is fitted therein, but a part of the terminal 29 is blanked to form a bent elastic fixing piece 30. It is caught and fixed inside the rectangular hole 28 or 28 ', and at the same time, the spring bearing 27 is supported by the back of the terminal 29, and the wire crimping piece 31 is attached to the lower end of the terminal 29. This is formed so that the wire 32 is crimped connection.

이와 같은 본 고안 실시예의 작용 효과를 설명하면, 조립시는 스프링받이(27)를 브러쉬 홀더(23)의 직사각구멍(28)(28')안으로 밀어 넣은 상태에서 그 직사각 구멍(28)(28')으로 전선(32)이 압착연결된 터미널(29)을 밀어 끼우면 그 중앙의 탄성 고정편(30)이 상기 직사각 구멍(28)을 통과한 직후에 그 내측에 걸려 고정됨으로써 조립 완료된다. (제 3 도 참조) 조립과 동시에 브러쉬 홀더(23)에 삽입된 브러쉬(24)의 스프링받이(27)는 제 4 도와 같이, 터미널(29)이면에 접촉 지지되는데 상기 스프링받이(27)와 터미널(29)은 상호 면접상태로 접촉지지되므로 전기적인 접촉이 양호하고 또한 기구적으로도 상기 스프링받이(27)의 지지상태가 안정되어 이에 지지되는 스프링(26) 역시 안정되므로 브러쉬(24)의 압력이 일정하게 유지되는 것이다. 또 상기 브러쉬(24)에 전원을 공급하기 위한 전선(32)을 접속시킴에 있어서도 종래와 같이 납땜하지 않고 상기 터미널(29)의 압착편(31)에 직접 연결되므로써 그 작업이 훨씬 수월해지는 것이다. 만일 브러쉬(24)가 마모되어 교체하고자 할 경우에는 제 3 도에서와 같이 브러쉬 홀더(23)의 직사각 구멍(28)에 끼워져 그 탄성고정편(30)으로 고정된 터미널(29)을 분리시키면 되는데 이때 상기 탄성고정편(30)을 눌러 주어 그 걸림상태를 해제시킴으로써 터미널(29)의 분리가 가능해진다. 그러면 브러쉬 홀더(23)내의 브러쉬(24)를 그대로 빼낼 수 있으므로 브러쉬의 교체작업이 용이한 것이다.When explaining the operation and effect of this embodiment of the present invention, the assembly of the rectangular holes 28, 28 'in the state in which the spring holder 27 is pushed into the rectangular holes 28, 28' of the brush holder 23 during assembly. If the wire 32 is pressed into the terminal 29 is crimped connection by pressing the elastic fixing piece 30 in the center thereof immediately after passing through the rectangular hole 28, the assembly is completed by being fixed inside. (See FIG. 3) At the same time as the assembly, the spring receiver 27 of the brush 24 inserted into the brush holder 23 is supported in contact with the rear surface of the terminal 29 as shown in the fourth diagram. (29) is in contact with each other because the contact is in good electrical contact and also the mechanical support of the spring bearing 27 is stabilized, the spring 26 is also supported thereon, so that the pressure of the brush 24 This will remain constant. In addition, even when connecting the electric wire 32 for supplying power to the brush 24, the operation is much easier by connecting directly to the crimping piece 31 of the terminal 29 without soldering as in the prior art. If the brush 24 is worn out and is to be replaced, as shown in FIG. 3, the terminal 29 is inserted into the rectangular hole 28 of the brush holder 23 and the terminal 29 fixed to the elastic fixing piece 30 is removed. At this time, by pressing the elastic fixing piece 30 to release the locking state of the terminal 29 can be separated. Then, since the brush 24 in the brush holder 23 can be taken out as it is, brush replacement is easy.

이상에서 설명한 바와 같이 본 고안은 전선이 직접 연결되는 터미널로써 브러쉬를 지지시키는 것이므로 구성이 간단하면서도 조립성 향상, 브러쉬의 지지력 향상 등에 기여하는 효과적인 고안이다.As described above, since the present invention supports the brush as a terminal to which an electric wire is directly connected, the present invention is simple and effective, contributing to the improvement of assemblability and improving the bearing capacity of the brush.
