Description

트랜스포머{Transformer}Transformer

본 고안은 트랜스포머에 관한 것이다.The present invention relates to a transformer.

일반적으로, LCD 인버터는 DC/DC(직류/직류) 변환부, DC/AC(직류/교류) 변환부등으로 나뉘었다.In general, the LCD inverter is divided into a DC / DC (direct current / direct current) conversion unit, a DC / AC (direct current / AC) conversion unit.

DC/DC(직류/직류) 변환부는 직류 전압을 발생시키고 진폭 변조하여 휘도를 제어하였고, DC/AC(직류/교류) 변환부는 트랜스포머에 의해 직류 전압을 교류 전압으로 승압하여 램프를 점등하였으며 점등 이후에는 적정 전압을 유지하도록 하였다.DC / DC (DC / DC) converter generates DC voltage and modulates amplitude to modulate the brightness. DC / AC (DC / DC) converter boosts DC voltage to AC voltage by transformer to turn on lamp. In order to maintain the proper voltage.

이때, 종래 트랜스포머는 열 가속 시험을 통하여 자계 신뢰성을 확보한 후, 인버터에 장착되었다.At this time, the conventional transformer is mounted on the inverter after securing the magnetic field reliability through the thermal acceleration test.

그러나, 종래 트랜스포머는 보빈과 코어 사이의 열팽창계수의 차에 의해 코어의 변형이 일어나거나, 심각하게는 코어가 크랙되는 문제점이 있었다.However, the conventional transformer has a problem that the deformation of the core due to the difference in the coefficient of thermal expansion between the bobbin and the core, or seriously cracks the core.

따라서, 종래 트랜스포머는 자계의 효율이 떨어져 제품의 품질을 저하시키므로, 제품의 품질을 위해 트랜스포머의 제작비용이 늘어나는 문제점이 있었다.Therefore, the conventional transformer has a problem in that the efficiency of the magnetic field is lowered and the quality of the product is lowered, so that the manufacturing cost of the transformer is increased for the quality of the product.

본 고안의 목적은, 트랜스포머의 제작비용의 상승을 억제시킬 수 있는 트랜스포머를 제공하는데에 있다.An object of the present invention is to provide a transformer that can suppress an increase in the manufacturing cost of a transformer.

이러한 목적을 달성하기 위하여 본 고안은 코일을 포함하는 보빈과, 보빈에 끼워져 자계를 형성하는 코어 및 보빈의 일부분에 복수개 제공되고, 보빈과 코어를 서로 이격시키는 돌출 부재를 포함한다.In order to achieve the above object, the present invention includes a bobbin including a coil, a plurality of cores and a protruding member spaced apart from each other, provided in a plurality of cores and a part of the bobbin fitted to the bobbin to form a magnetic field.

상기한 바와 같이 이루어진 본 고안의 트랜스포머에 따르면, 다음과 같은 효과를 얻을 수 있다.According to the transformer of the present invention made as described above, the following effects can be obtained.

트랜스포머의 제작비용의 상승을 억제시킬 수 있는 효과가 있다.There is an effect that can suppress the increase in the manufacturing cost of the transformer.

이하에서는 첨부된 도면을 참고로 하여 본 고안의 바람직한 실시예를 보다 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

도 1은 본 고안의 일실시예에 따른 트랜스포머를 나타낸 측면도이다.1 is a side view showing a transformer according to an embodiment of the present invention.

도 1을 참조하면, 본 고안의 일실시예에 따른 트랜스포머(100)는 보빈(102), 코어(104a, 104b), 돌출 부재(106)등을 포함한다.Referring to FIG. 1, a transformer 100 according to an embodiment of the present invention includes a bobbin 102, cores 104a and 104b, a protruding member 106, and the like.

보빈(102)은 도시하지는 않았지만 권선되어 있는 코일(미도시)을 포함하고 이후에 진술할 코어(104a, 104b)와 체결되어 코어(104a, 104b)를 수용하도록 제작 된다.The bobbin 102 includes a coil (not shown), although not shown, and is fabricated to receive the cores 104a and 104b in engagement with the cores 104a and 104b to be described later.

코어(104a, 104b)는 각각 'E'자 형상으로 형성되고, 보빈(102)에 각각 끼워 져 자계를 형성한다.The cores 104a and 104b are each formed in an 'E' shape, and are respectively fitted to the bobbin 102 to form a magnetic field.

이때, 보빈(102)의 일부분에 돌출 부재(106)가 더 장착된다.At this time, the protruding member 106 is further mounted to a part of the bobbin 102.

더욱 자세하게 말하면, 돌출 부재(106)는 보빈(102)의 일부분에 장착되되 보빈(102)과 코어(104a, 104b)를 서로 이격시키도록 장착된다.More specifically, the protruding member 106 is mounted to a portion of the bobbin 102 but spaced apart from the bobbin 102 and the cores 104a and 104b.

즉, 돌출 부재(106)는 코어(104a, 104b)의 가장자리 일부분과 대향되는 보빈(102)의 일부분에 장착된다.That is, the protruding member 106 is mounted to a portion of the bobbin 102 opposite the edge portions of the cores 104a and 104b.

이때, 돌출 부재(106)는 복수개로 장착되어 서로 대칭을 이루거나, 도시하지는 않았지만 서로 비대칭을 이룰 수가 있다.At this time, the plurality of protruding members 106 may be mounted to be symmetrical with each other, or may be asymmetrical with each other, although not illustrated.

즉, 돌출 부재(106)는 코어(104a, 104b)의 바닥면과 접촉되는 보빈(102)의 상측중 가장자리 일부분에 4개, 6개, 8개중 어느 하나로 서로 대칭을 이룰 수 있거나 서로 비대칭을 이룰 수가 있다.That is, the protruding members 106 may be symmetrical to each other or asymmetric to one of four, six, or eight on the edge portion of the upper side of the bobbin 102 in contact with the bottom surfaces of the cores 104a and 104b. There is a number.

또한, 도시하지는 않았지만, 돌출 부재(106)는 코어(104a, 104b)의 바닥면과 접촉되는 보빈(102)의 상측중 가장자리 일부분에 3개, 5개, 7개중 어느 하나로 서로 대칭을 이룰 수 있거나 서로 비대칭을 이룰 수가 있다.In addition, although not shown, the protruding members 106 may be symmetrical with one of three, five, or seven on the edge portion of the upper side of the bobbin 102 in contact with the bottom surfaces of the cores 104a, 104b, or It can be asymmetric with each other.

즉, 돌출 부재(106)의 위치와 갯수에 따라 열 가속 시험을 통하여 얻을 수 있는 자계의 신뢰성이 달라질 수가 있게 된다.That is, the reliability of the magnetic field obtained through the thermal acceleration test may vary depending on the position and the number of the protruding members 106.

이와 같은, 본 고안의 일실시예에 따른 돌출 부재(106)는 코어(104a, 104b)와 보빈(102)을 서로 이격시키게 되므로, 열 가속 시험을 통하여 자계 신뢰성을 테 스트할 시에 보빈(102)이 받는 열팽창 또는 열수축의 유효면적을 골고루 분산시킬 수가 있어, 코어(104a, 104b)가 받는 인장 응력을 최소화시킬 수가 있게 된다.As such, since the protruding member 106 according to the embodiment of the present invention spaces the cores 104a and 104b and the bobbin 102 from each other, the bobbin 102 is tested when the magnetic field reliability is tested through a thermal acceleration test. The effective area of thermal expansion or thermal contraction received by?) Can be evenly distributed, so that the tensile stress applied to the cores 104a and 104b can be minimized.

따라서, 본 고안의 일실시예에 따른 트랜스포머(100)는 코어(104a, 104b)가 변형되거나 크랙되는 것을 최소화시킬 수가 있어 자계의 효율을 유지시킬 수가 있게 된다.Therefore, the transformer 100 according to an embodiment of the present invention can minimize the deformation or cracking of the cores 104a and 104b, thereby maintaining the efficiency of the magnetic field.

이에 따라, 본 고안의 일실시예에 따른 트랜스포머(100)는 제품의 품질을 위해 새롭게 제작되는 트랜스포머(100)의 제작비용의 상승을 억제시킬 수가 있게 된다.Accordingly, the transformer 100 according to an embodiment of the present invention can suppress the increase in the manufacturing cost of the transformer 100 is newly manufactured for the quality of the product.

본 고안이 속하는 기술분야의 당업자는 본 고안이 그 기술적 사상이나 필수적 특징을 변경하지 않고서 다른 구체적인 형태로 실시될 수 있다는 것을 이해할 수 있을 것이다. 그러므로 이상에서 기술한 실시예는 모든 면에서 예시적인 것이며 한정적인 것이 아닌 것으로서 이해되어야 하고, 본 고안의 범위는 상기 상세한 설명보다는 후술하는 실용신안등록청구범위에 의하여 나타내어지며, 실용신안등록청구범위의 의미 및 범위 그리고 그 등가개념으로부터 도출되는 모든 변경 또는 변형된 형태가 본 고안의 범위에 포함되는 것으로 해석되어야 한다.Those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. Therefore, the embodiments described above are to be understood as illustrative and not restrictive in all respects, and the scope of the present invention is represented by the utility model registration claims to be described later rather than the detailed description, and the scope of utility model registration claims. All changes or modifications derived from meaning and scope and equivalent concepts should be construed as being included in the scope of the present invention.
