본 고안은 뮤동조(μ-Tuning)를 이용한 카라디오(Car Radio)의 튜우너용 FM 보빈에 대한 것이다.The present invention relates to an FM bobbin for a tuner of Car Radio using mu-tuning.
종래의 FM 보빈은 제 4 도에서 보는 바와 같이 코일을 감기 위함 홈(22)을 나선상으로 요입 형성시킨 보빈(21)의 일단부측에는 베이스 지지부(23)를, 타단부측에는 케이스 지지부(22)를 원판형상으로 되게 빙둘러 돌출시켜 구성하였는데, 이 보빈은 사용시 나선상 홈(22)에 코일을 감은 다음 삽입구의 반대측에 결합공을 뚫은 원통형의 알루미늄 케이스에 케이스 지지부(24)가 내측으로 들어가도록 끼워 이 지지부는 상기 결합공의 내주면에 받쳐지게 하고, 보빈(21'), (21)의 타단부는 결합공에 끼워지게 하여 상기 보빈이 케이스내에 결합되게 하며, 이렇게 결합시킨 다음 케이스를 튜우너의 프레임과 코일베이스 사이에 개재시켜 고정 스크류들을 사용하여 이들을 결착 고정토록 하였다.In the conventional FM bobbin, as shown in FIG. 4, the base support part 23 is provided at one end side of the bobbin 21 in which the grooves 22 are spirally formed to spiral the coil, and the case support part 22 is provided at the other end side. This bobbin was configured to protrude round to form a disk, and in use, the bobbin was wound around the spiral groove 22 and inserted into the cylindrical aluminum case in which a coupling hole was drilled on the opposite side of the insertion hole so that the case support 24 could be inserted inward. The support portion is supported by the inner circumferential surface of the coupling hole, and the other ends of the bobbins 21 'and 21 are fitted into the coupling holes so that the bobbins are coupled in the case, and then the case is combined with the frame of the tuner. It was interposed between the coil bases to bind and fix them using fixing screws.
그러나 각 스크류의 조임 상태에 따라 보빈(21)의 케이스 지지부(24)가 사출 성형시 평면이 맞지 않고 편차가 발생되는 경우에는 상기 지지부는 전체적으로 관통공의 내주면에 균일하게 밀착되지 않게 되어 부분적으로 틈새가 생기게 되기 때문에 보빈이 확실하고도 안정되게 고정되지 못하게 되므로 약간의 충격에 의해서도 유동되며, 이에따라 잡음(Micro Phonic)이 발생되는 폐단이 있었음은 물론 이를 방지하기 위해 고정 스크류를 과도하게 조여주며 기구물 파손등의 많은 문제점들이 있었다.However, if the case support portion 24 of the bobbin 21 is not flat when injection molding is caused by the tightening state of each screw, and the deviation occurs, the support portion is not uniformly adhered to the inner circumferential surface of the through hole as a whole. Since the bobbin cannot be fixed reliably and stably, it also flows due to a slight impact.Therefore, there was a closed end where noise (Micro Phonic) was generated. There were a lot of problems.
본 고안은 이러한 점들을 해결하기 위해 고안한 것으로 보빈에 케이스 지지부를 연설함에 있어, 이 지지부의 적정 개소를 절개하여 지지부가 수개의 텐션지지편으로 분활 구성되게 함과 동시에 각 지지편에는 각기 받침돌기를 돌출시켜주므로 이들 돌기가 케이스의 결합공 내주면에 접촉되어 눌려지게 되면 그 눌림량이 텐션지지편들의 텐션 작용에 의해 완충되게 함과 동시에 각 지지편들의 돌기가 모두 내주면에 접촉될 수 있게 되기 때문에 보빈의 고정 상태가 안정되며 이에따라 잡음 발생 현상이 감소되게 한 것이다.The present invention was devised to solve these points, and in addressing the case support to the bobbin, an appropriate location of the support was cut to allow the support to be divided into several tension support pieces, and at the same time, each support piece has a support protrusion. Since these protrusions are pressed against the inner circumferential surface of the coupling hole of the case, the pressing amount is buffered by the tension action of the tension support pieces, and at the same time, all the protrusions of the support pieces can contact the inner circumferential surface of the bobbin. The fixed state is stabilized and accordingly noise is reduced.
이하 본 고안의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
나선홈(2)에 코일(3)을 나선상으로 감은 보빈(1)을 내장한 알루미늄 케이스(4)를 튜우너 프레임(5)과 코일베이스(6) 사이에 개재시켜 수정 스크류(7)를 결착 고정하고, 상기 몸체의 중앙 유통구(T)로는 조정나선축(8)에 의해 전후진 되게 코어(9)를 결합시켜 이 코어의 삽입 정도에 따라 코일(3)의 인덕턴스가 증감되어 동조주파수를 가변토록 한 튜우너(10)에 있어서, 상기 보빈에는 코일 베니스 지지부(11)와 케이스 지지부(12)를 각기 단부측에 일체로 연설하되, 이 케이스 지지부는 적정 개소의 절개부(13)에 의해 수개의 텐션지지편(14)으로 분활되게 하고, 각 지지편의 외면에는 반구형상의 받침돌기(15)를 각기 돌출시켜 이들 받침 돌기가 알루미늄케이스(4)의 결합공(4') 내주면에 밀착 되도록 하여서된 것이다.The quartz screw 7 is attached by interposing the tuner frame 5 and the coil base 6 with an aluminum case 4 having the bobbin 1 wound around the coil 3 in a spiral groove 2 between the tuner frame 5 and the coil base 6. And the core 9 is coupled to the central distribution port T of the body by the adjusting spiral shaft 8 so that the inductance of the coil 3 increases and decreases according to the degree of insertion of the core to adjust the tuning frequency. In the variable tuner 10, the coil veneer support part 11 and the case support part 12 are integrally addressed to the end side of the bobbin, and the case support part is provided by the incision 13 at the appropriate location. The tension support piece 14 is divided into several pieces, and each support piece has a hemispherical support protrusion 15 protruding from each other so that these support protrusions are in close contact with the inner circumferential surface of the coupling hole 4 'of the aluminum case 4. It is.
이와같이 구성된 본 고안은 케이스 지지부(12)를 절개부(13)에 의해 수개의 텐션지지편(14)으로 분활되게 형성하고, 이들 지지편에는 각기 받침돌기(15)들을 돌출시켰기 때문에 보빈(1)을 제 3 도에서 보는 바와 같이 케이스(4)에 내장시킨 다음에 프레임(5)과 코일 베이스(6) 사이에 개재시켜 고정스크류(7)로 결착시켜 주면, 각 텐션지지편(14)의 받침돌기(15)들이 케이스(4)의 결합공(4')측 내주면에 밀착되는데, 이때, 고정스크류(7)의 조임 정도에 따라 받침돌기(15)들은 그 밀착상태가 달라지게 되며, 이들 받침돌기에 가해지는 누름력은 텐션지지편(14)들에 전달되어, 이 지지편은 받침돌기(15)가 밀착되는 정도에 따라 내측으로 만곡되는 현상이 발생되어 텐션을 갖게 된다.The present invention configured as described above forms the case support 12 divided into several tension support pieces 14 by the incision portion 13, and since the support protrusions 15 are protruded from these support pieces, respectively, the bobbin 1 , As shown in FIG. 3, is embedded in the case 4, and then sandwiched between the frame 5 and the coil base 6 with a fixing screw 7 to support the tension supporting pieces 14. The protrusions 15 are in close contact with the inner circumferential surface of the coupling hole 4 'side of the case 4, at which time the support protrusions 15 are in close contact with each other according to the tightening degree of the fixing screw 7. The pressing force applied to the machine is transmitted to the tension support pieces 14, so that the support piece is inwardly curved in accordance with the degree to which the support protrusion 15 is in close contact with the tension.
따라서 본 고안은 사출 성형시 각 텐션 지지편 케이스 지지부(11)를 사출 성형시 각 텐션 지지편(14)들의 평면이 서로 맞지 않고 편차가 발생되어도 받침돌기(15)들의 눌림 상태에 따라 텐션지지편(14)이 내측으로 만곡되기 때문에 고정 스크류(7)의 조임 상태에 따라 편차에 관계없이 모든 받침돌기들이 내주면에 밀착될 수 있게 되어 보빈(1)은 알루미늄케이스(4)내에 안정되게 결합 고정되며, 또 각 텐션지지편(14)의 텐션에 의해 외부의 충격을 완충시켜 주는 작용도 하므로 보빈이 유동되는 것을 최소화 시켜 주게 됨은 물론 이에따라 카라디오의 사용시 잡음 발생이 대폭 감소되는등 매우 유용한 고안이다.Therefore, according to the present invention, even when the tension support piece case support part 11 is injection molded, the tension support pieces 15 are pressed in accordance with the pressed state of the support protrusions 15, even if the planes of the tension support pieces 14 do not match each other and a deviation occurs. Since the 14 is curved inward, all the supporting protrusions can be in close contact with the inner circumferential surface regardless of the deviation of the fixing screw 7 so that the bobbin 1 is stably fixed and fixed in the aluminum case 4. In addition, since the tension of each tension support piece 14 also acts to buffer the external impact, it is possible to minimize the flow of the bobbin, as well as to significantly reduce the noise generated when using the car radio is a very useful design.
