Description

진동모터의 코일 연결장치Coil Connection Device of Vibration Motor

본 발명은 진동모터의 코일 연결장치에 관한 것으로서, 더욱 상세하게는 코일의 리드선을 정류자의 정류단자에 와인딩(winding)한 다음 납땜으로 연결되도록 함으로써, 와인딩과 납땜을 자동으로 할수 있으므로 자동화에 따른 생산성이 향상되는 진동모터의 코일 연결장치에 관한 것이다.The present invention relates to a coil connecting device of a vibration motor, and more particularly, winding and soldering the lead wire of the coil to the commutator terminal of the commutator, and then connected by soldering, so that winding and soldering can be performed automatically, resulting in automation. It relates to a coil connecting device of the vibration motor to be improved.

일반적으로 진동모터는 핸드폰, 호출기 등에 내장되어 이들을 진동시키는 역할을 한다. 핸드폰, 호출기 등은 비교적 작기 때문에 진동모터는 소형으로 제작되어야 한다. 이러한 진동모터는 도 1에 도시된 바와같이 원통형으로 구성된 케이스(1)의 내부에 원통형의 슬리브(1a)가 일정한 깊이로 돌출 형성되며 슬리브(1a)의 외주연에 마그네트(3)가 구비되고 이의 내주연에는 회전축(2)이 베어링(2a)에 의해 지지된 상태로 설치된다. 그리고 회전축(2)의 일측단은 케이스(1)의 외부로 돌출된 상태에서 편심된 진동자(7)가 결합되고 회전축(2)의 타측단은 슬리브(1a)로부터 케이스(1)의 내부로 돌출된 상태에서 정류자(4)가 결합된다.In general, the vibration motor is embedded in a mobile phone, a pager, etc. and serves to vibrate them. Since mobile phones and pagers are relatively small, vibration motors must be made compact. Such a vibration motor has a cylindrical sleeve 1a protruding to a predetermined depth inside the case 1 having a cylindrical shape as shown in FIG. 1, and a magnet 3 is provided on the outer periphery of the sleeve 1a and its On the inner circumference, the rotating shaft 2 is installed in a state supported by the bearing 2a. One end of the rotating shaft 2 is coupled to the eccentric vibrator 7 while protruding to the outside of the case 1, and the other end of the rotating shaft 2 protrudes from the sleeve 1a to the inside of the case 1. In this state, the commutator 4 is coupled.

정류자(4)는 방사상으로 다수개의 정류단자(5)가 인서트형태로 결합되어 있으며 케이스(1)에는 브러쉬(8)가 구비되어 정류단자(5)와 접촉된다. 또한 마그네트(3)의 외주연에는 일정한 에어갭(air gap)을 유지하며 코어리스형 코일(6)이 구비되고 코일(6)의 선단은 정류자(4)의 외주면에 끼워져 결합된다. 그리고 정류단자(5)와 코일(6)의 리드선(6a)이 용접등의 수단으로 결합되어 회로적으로 연결된다.The commutator 4 is radially coupled with a plurality of commutator terminals 5 in the form of inserts, and the case 1 is provided with a brush 8 in contact with the commutator terminal 5. In addition, the outer periphery of the magnet (3) maintains a constant air gap (core gap) is provided with a coreless coil (6) and the tip of the coil (6) is fitted to the outer peripheral surface of the commutator (4) is coupled. The rectifying terminal 5 and the lead wire 6a of the coil 6 are connected by a circuit such as welding or the like.

이처럼 구성된 종래의 진동모터는 브러쉬(8)를 통하여 인가되는 전원이 정류단자(5)를 거쳐 코일(6)에 인가되면 마그네트(3)와의 상호작용에 의해 정류자 및회전축(2)이 회전된다. 회전축(2)이 회전되는 동안 선단에 형성된 진동자(7)에 의해 회전축(2)과 케이스(1)가 함께 진동을 일으키게 되며 이 과정에서 케이스(1)가 고정된 휴대폰, 호출기가 진동을 일으키게 된다. 따라서 이를 휴대하고 있는 사용자는 옆사람이 모른 상태에서 외부로부터 자신을 호출하고 있는 사실을 감지할수 있게 된다.In the conventional vibration motor configured as described above, when power applied through the brush 8 is applied to the coil 6 via the rectifying terminal 5, the commutator and the rotating shaft 2 are rotated by the interaction with the magnet 3. While the rotating shaft 2 is rotated, the rotating shaft 2 and the case 1 are caused to vibrate together by the vibrator 7 formed at the tip. In this process, the mobile phone and the pager to which the case 1 is fixed are vibrated. . Therefore, the user carrying it can detect the fact that the next person is calling himself from the outside without knowing.

그러나 종래의 진동모터는 코일(6)에 형성된 리드선(6a)을 정류자(4)의 정류단자(5)에 용접하는 과정에서 자동화가 어려운 단점이 있다. 정류자(4)에 형성된 정류단자(5)는 정류자(4)에 인서트된 상태에서 그 선단이 정류자(4)의 외주연으로 돌출되지 않음로 리드선(6a)을 와인딩할수 없다. 따라서 리드선(6a)과 정류단자(5)의 결합을 확실하게 하기위해 용접해야되는 기술상의 어려움이 있으며 또한 정류단자(5)가 인서트되어 정류자(4)에 결합됨으로 생산가격이 높아지는 등의 단점이 있다.However, the conventional vibration motor has a disadvantage in that automation is difficult in the process of welding the lead wire 6a formed on the coil 6 to the rectifying terminal 5 of the commutator 4. The rectifier terminal 5 formed in the commutator 4 cannot wind the lead wire 6a because the tip thereof does not protrude to the outer periphery of the commutator 4 in the state of being inserted into the commutator 4. Therefore, there is a technical difficulty to weld in order to ensure the coupling of the lead wire (6a) and the rectifier terminal (5), and also the disadvantages such that the production price is increased by inserting the rectifier terminal (5) is coupled to the commutator (4) have.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 정류단자에 코일의 리드선을 와인딩한 다음 납땜으로 연결할수 있도록 정류자의 구조를 개선함으로써, 리드선을 정류단자에 연결하는 작업을 자동으로 수행하는데 있어서, 그 자동화가 간단해지고 또한 정류자를 인서트로 구성할필요가 없어 생산가격이 저렴해지는 진동모터의 코일 연결장치를 제공함에 있다.The present invention was developed in view of the conventional problems, and an object of the present invention is to improve the structure of the commutator so as to connect the lead wire of the coil to the rectifying terminal and then soldered, thereby automatically connecting the lead wire to the rectifying terminal. In this case, the automation is simplified, and it is not necessary to configure the commutator as an insert, thereby providing a coil connecting device of a vibration motor which is cheap in production price.

The cylindrical commutator 10 serves to support the coil 17 by fitting the inner circumferential surface of the coil 17 to the outer circumferential surface. In the center of the commutator 10, a hole 11 into which the rotating shaft 2 is fitted is formed, and the terminal support part 12 protrudes from one side of the commutator 10 so as to surround the hole 11. In addition, a plurality of rectifying terminals 14 are provided radially on the outer circumferential surface of the terminal support part 12, and washers 16 are fitted to the outer circumferential surface of the terminal support part 12 to fix each rectifying terminal 14.

A semicircular arc-shaped winding groove 13 is provided on the surface of the commutator 10 so as to correspond to each winding part 15. Therefore, the winding part 15 of each commutation terminal 14 is kept excited by the winding groove 13.
