다음에, 상기 장치의 동작에 대해서 설명을 한다.Next, the operation of the apparatus will be described.
먼저, 회전 검출 장치를 자동차의 밋션 케이스와 같은 설치부에 설치판(3)의 설치구멍(3a)을 거쳐서 외부 체결용 나사로 고정한다. 이러한 경우, 폴(2)의 선단부(큰지름의 돌기부(2a)은 도시되지 않은 피검출 회전체의 등간간격 위치에 설치되는 각 돌기부에 대해 그 회전 궤적외부에 약간의 자기 갭을 거쳐서 마주 대하게 된다.First, the rotation detection device is fixed with an external fastening screw via an installation hole 3a of the mounting plate 3 in an installation portion such as a vehicle's mission case. In this case, the tip portion (large diameter projection 2a of the pole 2) is opposed to each of the protrusions provided at equally spaced positions of the to-be-detected rotating body via a slight magnetic gap on the outside of the rotation trajectory. .
그래서, 상기 설치 상태에 있어서는 피검출 회전체(도시않음)의 회전에 따라 개개의 돌기부가 폴(2)의 선단부분을 통과하여 접근 이격을 반복하며 따라서, 이를 양자간의 자기 저항이 변화하여, 이에 의해, 폴 피검출회전체의 돌기부와 외부를 거쳐서 스페이서(8)로 되돌아가는 자석(6)의 자속량이 변화한다. 그래서, 자기다발이 코일(5)에 고리 모양으로 교체 형성되어 있으므로, 코일(5)에는 자기 저항의 변화에 대응한 신호 전압이 유기되어, 신호 전압의 변화 주기를 계측해서, 피검출 회전체의 회전속도(자동차의 주행 속도등)를 검출하는 것이다.Thus, in the installation state, as each of the projections (not shown) rotates, the individual projections pass through the tip of the pole 2 and repeat the approach separation, and thus the magnetic resistance between them changes, As a result, the amount of magnetic flux of the magnet 6 returned to the spacer 8 through the protrusion and the outside of the pole-detected rotating body changes. Therefore, since the magnetic bundles are alternately formed in the coil 5, the signal voltage corresponding to the change in the magnetic resistance is induced in the coil 5, and the period of change of the signal voltage is measured to It is to detect the rotation speed (driving speed of the car, etc.).
여기에서, 종래의 터미널(11)과 코일 단부(5a)와의 접속방법을 설명하면, 먼저 코일 단부(5a)를 터미널(11)에 역어 매어서 납땜 접착한후, 터미널(11)의 꺽기를 한다. 한편, 코일단말부의 처리는 터미널(11)에 엮은 후, 터미널(11)의 날카로운 모서리를 이용하여 인장 절단하였다.Herein, a conventional method of connecting the terminal 11 and the coil end 5a will be described. First, the coil end 5a is tied to the terminal 11, soldered and bonded, and then the terminal 11 is bent. . On the other hand, the process of the coil terminal was woven to the terminal 11, and then tension-cutting was carried out using the sharp edge of the terminal 11.
또한, 상기 터미널(11)의 꺾어 넘김에 의해 코일(5)에 일정한 느슨한 여유가 생긴다.Further, by turning over the terminal 11, a constant loose margin is generated in the coil 5.
또한, 회전 검출 장치의 검출 신호는 코일(5)의 감은 수에 비례하기 때문에, 코일(5)에는 극히 가는선이 사용되고 있다. 왜냐하면 한정된 스페이스의 중앙에서 최대의 출력격신호가 얻어지기 때문이다.Further, since the detection signal of the rotation detection device is proportional to the number of turns of the coil 5, an extremely thin line is used for the coil 5. This is because the maximum output power signal is obtained in the center of the limited space.
종래의 회전 검출 장치에서는 코일단부(5a)를 터미널(11)에 엮을때 터미널(11)의 날카로운 모서리에 의해 코일 재에 흠으로 단선의 위섬성이 있었다.In the conventional rotation detection apparatus, when weaving the coil end 5a to the terminal 11, the edge of the terminal 11 was flawed in the coil member, and there was a disconnection of false wire.
또한, 납땜 접속후, 터미널(11)을 꺾어 넘김으로서 코일(5)에 납땜접속되어 있는 부분과 납땜 접속되어 있지 아니한 경계부에 구브림 응력이 발생하여 단선이 발생하기가 쉬웠다.In addition, after the soldering connection, the terminal 11 was turned over to cause bending stress to occur at the boundary portion not soldered to the portion connected to the coil 5 and to cause disconnection.
본 고안은 상기 문제점들을 해소하기 위한 것으로, 코일 단부와 터미널과의 접속이 양호하고, 또한 신뢰성을 갖는 회전 검출장치를 얻는 것을 목적으로 한다.The present invention has been made to solve the above problems, and an object of the present invention is to obtain a rotation detecting device having a good connection between a coil end and a terminal and having a high reliability.
제1의 고안에 따른 회전 검출 장치는, 그 단말부 처리에 있어서 코일 단부를 터미널의 절곡부를 거쳐서 유도하며, 또한 터미널에 설치한 홈부 또는 구멍을 통해서 엮어지는 특징으로 하는 것이다.The rotation detecting apparatus according to the first invention is characterized in that the coil end is guided through the bent part of the terminal in the terminal part processing, and is woven through the groove part or the hole provided in the terminal.
또한, 제2의 고안에 따르는 회전 검출 장치는, 그 단말부처리에 있어서, 코일 단부의 터미널로의 납땜접속을 터미널의 절곡부위에서 행함과 동시에 외부 인출용 리이드 와이어의 코어 와이어와 함께 터미널 홈부에 있어서도 행하는 것을 특징으로 하는 것이다.Further, in the terminal portion processing, the rotation detection device according to the second aspect of the present invention performs soldering connection of the coil end to the terminal at the bent portion of the terminal and at the same time as the terminal groove portion together with the core wire of the lead wire for external drawing. It is also characterized by.
제1고안의 회전 검출 장치에 의하면, 코일 단부를 터미널의 절곡부를 거쳐서 유도하고 있으므로, 극히 가는 선의 코일 단부가 터미널의 날카로운 모서리에서 잘단되는일이 없어지며 신뢰성이 향상된다.According to the rotation detection device of the first design, since the coil end is guided through the bent portion of the terminal, the coil end of the extremely thin line is not cut off at the sharp edge of the terminal and the reliability is improved.
또한, 제2고안의 회전 검출장치에 의하면, 코일 단부의 터미널의 납땜 부착이 그곳에서 행해지므로, 한편에서는 터널납땜이 행해져도, 또 다른 한편의 부분에서는 접속되어지게 되어, 신뢰성이 향상된다.In addition, according to the rotation detection device of the second design, since the soldering of the terminal at the coil end is performed there, even if tunnel soldering is performed on the one hand, it is connected in the other part, thereby improving reliability.
다음에, 본 고안의 한 실시예를 첨부 도면을 참고로 하여 설명한다.Next, an embodiment of the present invention will be described with reference to the accompanying drawings.
제1도는 본 실시예에 의한 회전 검출 장치의 코일 단부와 터미널과의 접속부를 설명하기 위한 분해 사시도이며, 도면에 있어서, 코일(5)의 감기 마감 단부(감기 개시 단부)(5a)를 터미널(11)의 절곡부(11e)의 상부를 거쳐서 유도하며, 터미널 상단에 형성한 U 홈(11c)을 통과시켜, 터미널의 횡 방향에 설치한 오목한 형상의 엮임부(11d)에서 엮어준다. 이때, 코일단부(5a)는 터미널(11)의 날카로운 모서리에 접속하는 일이 없이, 절곡부(11e)의 둥근 부분(11f)에 의해 유도되므로 단선의 위험성은 없다.FIG. 1 is an exploded perspective view for explaining the connection portion between the coil end and the terminal of the rotation detecting device according to the present embodiment. In the drawing, the winding finishing end (cold start end) 5a of the coil 5 is connected to the terminal ( It guides through the upper part of the bent part 11e of 11), passes through the U groove 11c formed in the upper end of the terminal, and weaves it in the concave woven part 11d provided in the transverse direction of the terminal. At this time, since the coil end portion 5a is guided by the rounded portion 11f of the bent portion 11e without being connected to the sharp edge of the terminal 11, there is no risk of disconnection.
그래서, 터미널의 절곡부(11e)상부에 있어서 코일단부(5a)의 납땜질(납 20a)을 행함과 동시에, 터미널의 U홈(11c)에 있어서도 리이드 와이어(12)의 코어 와이어부(12a)와 함께 코일단부(5a)의 납땜을 행한다.Therefore, the soldering (lead 20a) of the coil end portion 5a is performed on the bent portion 11e of the terminal and the core wire portion 12a of the lead wire 12 also in the U groove 11c of the terminal. In addition, the coil end 5a is soldered.
또한, 코일 단부(5a)의 단말부는 엮임부(11d)에서 엮어준후, 날카로운 모서리 이기도한 엮임부(11d)의 각부를 이용하여, 코일을 인장 절단시킬 수가 있어, 작업성이 향상된다.In addition, after the terminal portion of the coil end 5a is woven in the woven portion 11d, the coils can be tensilely cut using the respective portions of the woven portion 11d, which is also a sharp edge, thereby improving workability.
한편, 터미널의 고정부(11a)는 보빈(4)의 홈부(4a,4b)에 끼워맞추어 고정시킨다.On the other hand, the fixing portion 11a of the terminal is fitted into the groove portions 4a and 4b of the bobbin 4 to be fixed.
또한, 그밖의 구성부분은 종래와 동일하며, 그 설명은 생략한다.In addition, the other components are the same as the conventional one, and the description thereof is omitted.
이상과 같이, 본 고안에 따라 터미널의 단부가 절곡되어 있으므로, 극히 가는선의 코일 단부가 종래와 같이 터미널의 날카로운 모서리에 접촉하지 않게되어, 절단의 위험성이 없고 신뢰성이 향상된다.As described above, since the end portion of the terminal is bent according to the present invention, the coil end of the extremely thin line does not come into contact with the sharp edge of the terminal as in the prior art, and there is no risk of cutting and reliability is improved.
또한, 특히 가는선의 코일의 납땜 처리가 두곳에서 행해지므로, 한편에서 있어서 터널 납땜이 행해져도, 다른 한편의 부분에서 접속되어 있으므로 접속의 신뢰성이 향상된다.In addition, in particular, since the brazing process of the thin wire coil is performed at two places, even if tunnel soldering is performed on the one hand, the connection reliability is improved because it is connected at the other part.
