In particular, batteries of portable information and communication devices have ultra-thin and low power consumption for extending the life of the battery. It demands a product (low DC resistance).

이와같은 요구사항을 충족시키기 위해 근래에는 두께가 1.2mm이하인 초박형 부품을 요구하고 있어, 인덕터또한 초박형으로 형성됨에 따라 동선코일의 권선층(LAYER)은 동선의 두께를 고려하여 불가피하게 2단권선구조를 갖게 된다.In order to meet such requirements, in recent years, ultra-thin components having a thickness of 1.2 mm or less are required. As the inductor is also made ultra-thin, the winding layer (LAYER) of the copper coil has an unavoidable two-stage winding structure in consideration of the thickness of the copper wire. Will have

도 1a는 종래 초박형 인덕터의 코일권선구조를 보인 측단면도이고, 도 1b는 종래 초박형 인덕터 코일의 사시도로서, 종래에는 도 1a와 같이 드럼코아(200)의 권심부(210)에 코일(300)을 권선하여 인덕터(100)를 생산하거나, 도 1b에서와 같이 권선된 코일(300)을 페라이트 코어(FERRITE CORE)등에 삽입하여 인덕터를 생산하는데, 이러한 도 1a,b에 도시된 동선 코일은 모두 동일한 권선구조를 갖는 것이다.Figure 1a is a side cross-sectional view showing a coil winding structure of a conventional ultra-thin inductor, Figure 1b is a perspective view of a conventional ultra-thin inductor coil, conventionally the coil 300 to the core 210 of the drum core 200 as shown in Figure 1a Winding to produce an inductor 100, or as shown in Figure 1b to insert the coiled coil 300 in a ferrite core (FERRITE CORE) and the like to produce an inductor, all of the copper coil shown in Figure 1a, b is the same winding It has a structure.

하지만, 상기와 같은 종래 인덕터(표면실장용 파워 인턱터 등 : 100)의 권선구조는 권선작업시 권심부(210)에 인입되는 동선의 권선시작부(310)를 통상의 권선기에 고정시킨 상태에서 코일(200)을 형성함에 따라 권선시작부(310)가 인입되는 상층(320)은 하층(330)과 같은 유효권선층이 될 수 없는 구조를 갖는 것인데,However, the winding structure of the conventional inductor (surface-mounted power inductor, etc.) as described above is a coil (when the winding start portion 310 of the copper wire, which is inserted into the core 210 in the winding operation, is fixed to a common winding machine). As the 200 is formed, the upper layer 320 into which the winding start part 310 is introduced has a structure that cannot be an effective winding layer such as the lower layer 330.

상기한 목적을 달성하기 위한 본 고안의 구체적인 수단으로는;As a specific means of the present invention for achieving the above object;

권심의 내측에서 권심의 외측으로 동싱에 권취되는 상부권선층과 하부권선층이 드럼코아에 교차권선되는 초박형 인버터의 코일권선구조를 구비하므로서 달성된다.It is achieved by providing a coil winding structure of an ultra-thin inverter in which an upper winding layer and a lower winding layer wound on the copper core from the inside of the core to the outside of the core are wound around the drum core.

이때, 드럼코아에 권선되는 동선은 권선후 풀어지거나 변형되는 것을 방지하기 위해 열풍이나 알코올로 접착경화할 수 있는 자기접착동선을 사용할 수도 있다.At this time, the copper wire wound on the drum core may use a self-adhesive copper wire that can be adhesively cured with hot air or alcohol to prevent the wire from being unwound or deformed after winding.

이하, 본 고안의 바람직한 실시예를 첨부도면에 의거 상세히 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 고안에 따른 초박형 인덕터의 코일권선구조를 설명하기 위한 코일의 사시도이며, 도 3은 본 고안에 따른 초박형 인덕터의 코일권선구조를 설명하기 위한 인덕터의 측단면도이다.2 is a perspective view of a coil for explaining the coil winding structure of the ultra-thin inductor according to the present invention, Figure 3 is a side cross-sectional view of the inductor for explaining the coil winding structure of the ultra-thin inductor according to the present invention.

이에 도시된 바와같이 본 고안의 코일권선구조는 상부권선층(3)을 유효권선층화 한 것을 특징적인 구성으로 하는데, 이는 드럼코아(6)에 권선을 시작할때 종래와 같이 권선시작부를 권선기에 고정시키지 않고, 하부권선층(4)과 교차하는 형태로서 교차권선하여 상부권선층(3)을 형성한 것이다.As shown therein, the coil winding structure of the present invention has a characteristic configuration in which the upper winding layer 3 is effectively wound, which does not fix the winding start portion to the winding machine as in the prior art when the winding of the drum core 6 is started. Instead, the upper winding layer 3 is formed by cross winding as a form that intersects the lower winding layer 4.

이와같은 본 고안의 코일권선구조는 통상의 권선기에 의해 코일(2)을 형성함에 있어, 기존과 같이 권선시작부(상부권선종료부(31))를 권선기에 고정하지 않고 소정의 길이를 갖는 일자동선의 양 끝단(상부권선종료부(31)와 하부권선종료부(41))을 소정의 탄성을 갖는 지그를 통해 잡은 상태에서 일자동선의 중심에서부터 상부권선층(3)과 하부권선층(4)이 형성되도록 동시에 교차권선하게 된다.In the coil winding structure of the present invention, in forming the coil 2 by a common winding machine, a single automatic line having a predetermined length without fixing the winding start portion (upper winding end portion 31) to the winding machine as in the conventional art.

At the same time, the windings are formed so that they form.

이에따라, 도 3에서와 같이 교차권선의 시작점인 일자동선의 중심을 교차권선부(5)로 하여 상부권선층(3)과 하부권선층(4)은 권심(21)의 내측에서 권심(21)의 외측으로 권선되는 형태를 취하게 된다.Accordingly, as shown in FIG. 3, the upper winding layer 3 and the lower winding layer 4 are formed inside the winding core 21 by using the center of the one automatic line, which is the starting point of the cross winding, as the crossing winding portion 5. Take the form of winding to the outside of the.

한편, 이와같은 권선구조를 갖는 동선은 드럼코아(6)에 권선후 풀리는 것을 방지할 수 있도록 열풍이나 알코올 등에 의해 경화하므로서 자기접합동선(SELF BONDING WIRE)을 적용함이 바람직하다.On the other hand, the copper wire having such a winding structure is preferably applied to the self bonding copper wire (SELF BONDING WIRE) by curing with hot air or alcohol so as to prevent loosening after winding to the drum core (6).

이에, 상기와 같은 권선구조를 갖는 본 고안의 초박형 인덕터(1)는 도 3에서와 같이 드럼코아(6)의 권심부에 권선할 경우, 상부권선종료부(31)가 위치한 상부권선층(3)은 하부권선종료부(41)가 위치한 하부권선층(4)과 같이 유효권선층으로 구성됨에 따라 기존의 권선구조에 비해 동일 권선영역에서 인덕턴스의 상승효과 및 직류저항의 감소효과를 얻을 수 있다.Thus, when the ultra-thin inductor 1 of the present invention having the winding structure as described above is wound around the core portion of the drum core 6 as shown in FIG. 3, the upper winding layer 3 in which the upper winding end portion 31 is located is located. ) Is composed of the effective winding layer, such as the lower winding layer (4) in which the lower winding end portion 41 is located, it is possible to obtain a synergistic effect of inductance and reduction of DC resistance in the same winding region compared to the existing winding structure.

이상과 같이 본 고안에 따른 초박형 인덕터의 코일권선구조는 교차권선을 통해 권선시작부가 인입되는 상부권선층또한 하부권선층과 같이 유효권선층으로 구성하므로서, 동일 권선영역에서 인덕턴스의 향상 및 직류저항의 감소효과를 얻을 수 있고, 이러한 성능향상으로 인해 인덕터가 실장되는 각종 부품을 초박형화할 수 있는 효과가 있다.As described above, the coil winding structure of the ultra-thin inductor according to the present invention is composed of the upper winding layer through which the winding start is drawn through the cross winding and also the effective winding layer such as the lower winding layer, thereby improving the inductance and reducing the DC resistance in the same winding region. Effects can be obtained, and the performance can be made extremely thin in various components on which the inductor is mounted.
