본 고안은 코일(Coil)과 세라믹 소자로 구성되는 조이즈 필터(Noise Filter)용 페라이트 코일의 결합구조에 관한 것으로 이는 특히, 원통상의 세라믹 소자 외주면에 권선코일의 설치가 용이하고 일정한 위치에서 상기 권선코일을 결합 고정하여 제품의 특성편차를 감소시킬 수 있도록 한 페라이트 코일의 결합구조에 관한 것이다.The present invention relates to a coupling structure of a ferrite coil for a noise filter composed of a coil and a ceramic element. In particular, it is easy to install a winding coil on an outer circumferential surface of a cylindrical ceramic element and at a predetermined position. The present invention relates to a coupling structure of a ferrite coil in which winding coils are fixed to reduce product characteristic deviations.

일반적으로 알려져 있는 노이즈 필터용 페라이트 코일의 결합구조에 있어서 제1도에 도시한 바와 같이, 원통상의 세라믹 소자(11) 외주면에 코일이 권선된 권선 코일(12)이 설치되고, 상기 권선코일(12)의 양측에는 코일리드(13)(14)가 각각 인출토록되는 한편, 상기 세라믹 소자(11) 외주면에 설치되는 권선코일(12)은 접착제(15)로서 결합 고정토록 되는 구조로 이루어졌다.In a commonly known coupling structure of a ferrite coil for a noise filter, as shown in FIG. 1, a winding coil 12 wound around a cylindrical ceramic element 11 is provided, and the winding coil ( Coil leads 13 and 14 are drawn out on both sides of 12, respectively, while the winding coil 12 installed on the outer circumferential surface of the ceramic element 11 has a structure in which the coil 15 is bonded and fixed.

상기와 같은 결합구조를 갖는 종래의 페라이트 코일은, 권선코일(12)의 외부로 노출되는 세라믹 소자(11)의 노출길이에 따라 노이즈 필터 특성에 커다란 영향을 미치게 되는 관계로, 원통상의 세라믹 소자(11) 외주면에 접착제(15)의 도포후, 권선코일(12)의 내경을 상기 세라믹 소자(11)의 외경에 삽입하여 일정길이만큼 삽입이 완료되면, 이를 경화후 노이즈 필터로 사용하게 되는 구조로 이루어진다.The conventional ferrite coil having the coupling structure as described above has a large influence on the noise filter characteristics according to the exposure length of the ceramic element 11 exposed to the outside of the winding coil 12, and thus is a cylindrical ceramic element. (11) After the adhesive 15 is applied to the outer circumferential surface, the inner diameter of the winding coil 12 is inserted into the outer diameter of the ceramic element 11, and when the insertion is completed by a predetermined length, the structure is used as a noise filter after curing. Is made of.

그러나, 이와 같은 종래의 권선코일(12) 결합구조는, 세라믹 소자(11)의 외주면에 권선코일(12)의 삽입시, 권선코일(12)의 삽입길이를 단지 작업자의 눈대중에 의해 결정토록 함으로써, 권선코일(12)의 세라믹 소자(11)에 불균일한 상태로 결합 고정됨은 물론, 이로 인하여 외부로 노출되는 세라믹 소자(11)의 고정위치가 각각 일정하지 않게 되어 제품의 특성 편차가 커지게 되는 문제점이 있었던 것이다.However, the conventional winding coil 12 coupling structure is such that when the winding coil 12 is inserted into the outer circumferential surface of the ceramic element 11, the insertion length of the winding coil 12 is determined only by the eyes of the operator. As a result, the fixed position of the ceramic element 11 exposed to the outside is not fixed to the ceramic element 11 of the winding coil 12 in a non-uniform state. There was a problem.

본 고안은 상기한 바와 같은 종래의 제반 문제점들을 개선시키기 위하여 안출된 것으로서 그 목적은, 원통상의 세라믹 소자 외주면으로 삽입되는 권선 코일의 설치 작업을 용이하게 수행할 수 있도록 하며, 상기 세라믹 소자의 일정한 위치에서 권선코일이 결합 고정토록 되어 제품의 특성 편차를 현저하게 감소 시키면서도 전기적 특성이 향상될 수 있는 노이즈 필터용 페라이트 코일 결합구조를 제공하는데 있다.The present invention has been made to improve the above-mentioned conventional problems, the object of which is to facilitate the installation work of the winding coil inserted into the outer peripheral surface of the cylindrical ceramic element, the constant of the ceramic element It is to provide a ferrite coil coupling structure for a noise filter which can improve the electrical characteristics while significantly reducing the variation in product characteristics by allowing the winding coil to be fixed at the position.

상기 목적을 달성하기 위한 기술적인 구성으로서 본 고안의 페라이트 코일 결합구조는, 양측에 코일 리드가 연설된 권선코일이 삽입 고정되는 원통상의 세라믹 소자 외주면 일정부위에 코일 고정 단턱을 형성 하여 이에 내삽되는 권선코일의 일측 단부가 사이 코일 고정 단턱에 거러려 고정토록 하는 구성으로 이루어진 노이즈 필터용 페라이트 코일 결합구조를 마련함에 의한다.As a technical configuration for achieving the above object, the ferrite coil coupling structure of the present invention is formed by inserting a coil fixing step on a predetermined portion of the outer circumferential surface of a cylindrical ceramic element into which a coil of coil coiled with a coil lead is inserted and fixed. By providing a ferrite coil coupling structure for the noise filter consisting of a configuration such that one end of the winding coil is fixed to the coil fixing step between.

이하, 첨부된 도면에 의거하여 본 고안에 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 고안에 따른 노이즈 필터용 페라이트 코일의 결합 상태를 나타낸 정면 구조도로서, 양측에 코일리드(3)(4)가 연설된 권선코일(2)이 삽입되는 원통상의 세라믹 소자(1) 외주면 일정부위에 코일 고정단턱(6)을 돌설하여 이에 내삽되는 권선코일(2)의 일측 단부가 상기 세라믹 소자(1)의 코일 고정단턱(6)에 걸려 고정토록 되는 구조로 이루어 진다.2 is a front structural view showing a coupling state of a ferrite coil for a noise filter according to the present invention, in which a cylindrical ceramic element 1 into which coil coils 3 and 4 wound coils 2 are inserted is inserted. One end of the winding coil 2 inserted into the coil fixing step 6 at a predetermined portion of the outer circumferential surface is caught in the coil fixing step 6 of the ceramic element 1 so as to be fixed.
