Description

사각형 에나멜 전선 및 사각형 에나멜 전선의 도체선{QUADRANGLE ENAMEL WIRE AND CONDUCTOR WIRE OF QUADRANGLE ENAMEL WIRE}QUADRANGLE ENAMEL WIRE AND CONDUCTOR WIRE OF QUADRANGLE ENAMEL WIRE}

본 발명은 에나멜 전선에 관한 것으로서, 더욱 구체적으로는 절연 피복층이 균일한 두께로 코팅될 수 있는 사각형 에나멜 전선 및 상기 절연 피복층 내부에 구비되는 사각형의 도체선에 관한 것이다.The present invention relates to an enameled wire, and more particularly, to a rectangular enameled wire in which an insulating coating layer can be coated with a uniform thickness and a rectangular conductor wire provided inside the insulating coating layer.

일반적으로 에나멜 전선은 절연전선으로서 전기기기 내부에서 코일의 형태로 감겨져 자기 에너지 변환과정을 통하여, 전기적 에너지와 기계적 에너지를 상호 변환시키는 역할을 한다. 이러한 에나멜 전선은 일반적으로 구리 등 도체선과 이를 둘러싸고 있는 절연 피복층으로 구성된다. 또한, 에나멜 전선의 절연 피복층은 유기용매와 고분자 수지로 이루어진 피복도료를 도체 표면에 도포하고 400℃이상의 고온에서 건조, 가교반응을 진행시켜서 형성한다. 여기서, 상기 피복도료는 유기용매 내에 고분자 수지 성분이 용해되거나 분산되어 있는 것이다.In general, enameled wire is wound in the form of a coil inside an electric device as an insulated wire and performs a role of mutually converting electrical energy and mechanical energy through a magnetic energy conversion process. Such enameled wire is generally composed of a conductor wire such as copper and an insulating coating layer surrounding it. In addition, the insulating coating layer of an enameled electric wire is formed by apply | coating the coating paint which consists of an organic solvent and a polymer resin on the surface of a conductor, and drying and advancing a crosslinking reaction at the high temperature of 400 degreeC or more. Here, the coating paint is a polymer resin component is dissolved or dispersed in an organic solvent.

이러한 에나멜 전선은 크게 환선형 에나멜선과 사각형 에나멜선으로 구별되며, 현재 중전기 제품, 자동차 부품, 가전제품, 의료기기 및 항공우주 산업의 핵심소재 등 다양한 분야에 쓰여지고 있다.These enameled wires are largely divided into round enameled wires and rectangular enameled wires, and are currently used in various fields such as heavy electric appliances, automotive parts, home appliances, medical devices, and core materials for the aerospace industry.

하지만, 종래 기술에 따른 사각형 에나멜 전선(30)은 도체선의 외부에 절연 피복층을 코팅할 때, 도체선(10)의 사각형상에 따라 절연 피복층(20)의 에지부분이 도 1a, 도 1b 및 도 1c의 점선으로 표시한 부분과 같이 균일한 두께로 형성되지 않는 에지 커버리지(Edge Coverage) 현상이 발생한다는 문제점이 존재한다. 그리고, 이렇게 균일하지 못한 두께로 형성된 에나멜 전선(30)을 전자기기 등에 코일로 이용했을 경우, 절연 불량의 원인이 되어 기기의 신뢰성이 현저히 저하된다.However, in the rectangular enameled wire 30 according to the related art, when the insulating coating layer is coated on the outside of the conductor wire, the edge portion of the insulating coating layer 20 is formed along the quadrangular shape of the conductor wire 10. There is a problem that an edge coverage phenomenon that does not have a uniform thickness, such as a portion indicated by the dotted line of 1c occurs. And when the enameled electric wire 30 formed in such a non-uniform thickness is used as a coil for an electronic device etc., it will become a cause of insulation failure and the reliability of a device will fall remarkably.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로서, 본 발명의 목적은 절연 피복층의 두께가 균일하게 코팅될 수 있는 사각형 에나멜 전선 및 사각형 에나멜 전선의 도체선을 제공하는 것이다.Accordingly, the present invention was devised to solve the above problems, and an object of the present invention is to provide a conductor wire of a rectangular enameled wire and a rectangular enameled wire in which the thickness of the insulating coating layer can be uniformly coated.

본 발명에 따른 다른 목적 및 장점들은 하기에서 설명될 것이며, 본 발명의 실시예에 의해 알게 될 것이다. 또한, 본 발명의 목적 및 장점들은 특허청구범위에 나타난 구성에 의해 실현될 수 있다.Other objects and advantages according to the invention will be described below and will be appreciated by the embodiments of the invention. In addition, the objects and advantages of the present invention can be realized by the configuration shown in the claims.

본 발명자들은 사각형 에나멜선의 절연 피복층을 코팅할 때 나타나는 에지 커버리지(Edge Coverage) 현상을 개선하기 위해 여러가지 검토를 한 결과, 도체선의 가로 및 세로의 길이비와 에지부(Edge Part)의 라운드 길이를 적절히 조절함으로써 상기 과제를 해결할 수 있다는 것을 알아내어 본 발명을 완성하였다. The present inventors have made various studies to improve the edge coverage phenomenon when coating an insulating coating layer of rectangular enamel wire, and as a result, the length and width ratio of the conductor line and the round length of the edge part are appropriately determined. The present invention was completed by finding out that the above problems can be solved by adjusting.

본 발명에 따른 사각형 도체선과 이 도체선을 둘러싸는 절연 피복층으로 구성되는 에나멜 전선에 있어서, 상기 도체선은 에지부가 라운드진 사각형상을 갖되, 아래의 수학식 1을 만족하는 것을 특징으로 한다.In the enameled wire consisting of a rectangular conductor wire according to the present invention and an insulating coating layer surrounding the conductor wire, the conductor wire has a rectangular shape with rounded edges, and the following Equation 1 is satisfied.

이와 같이, 본 발명에 따른 사각형 에나멜 전선 및 사각형 에나멜 전선의 도체선은 가로 및 세로의 길이비와 에지부의 라운드 길이를 조절함으로써 절연 피복층의 두께를 전체적으로 균일하게 형성할 수 있고, 이로 인해 전자기기의 작동신뢰성을 더욱 높일 수 있다.As described above, the conductor wires of the rectangular enameled wire and the rectangular enameled wire according to the present invention can form the thickness of the insulating coating layer as a whole by adjusting the length ratio of the width and length and the round length of the edge part, and thus Operational reliability can be further increased.

도 2는 본 발명에 따른 사각형 에나멜 전선의 일실시예를 도시한 도면이다. 도면을 참조하면, 본 발명의 사각형 에나멜 전선(30)은 구리 등 도체선(10)과 이를 둘러싸고 있는 절연 피복층(20)을 포함하여 구성된다. 상기 절연 피복층(20)은 도체선(10)에 코팅되는 물질로써 성분 구성에 따라 에나멜 전선(30)의 특성이 좌우된다.2 is a view showing an embodiment of a rectangular enameled wire according to the present invention. Referring to the drawings, the rectangular enameled wire 30 of the present invention includes a conductor wire 10 such as copper and an insulating coating layer 20 surrounding the conductor wire 10. The insulating coating layer 20 is a material coated on the conductor wire 10, and the characteristics of the enamel wire 30 depend on the component composition.

도 3은 상기 도 2의 도체선만을 별도로 도시한 단면도이다. 도시된 바와 같이, 상기 도체선(10)은 사각형으로 형성되되 각 에지부가 라운드지게 형성되며, 다음 수학식 1을 만족해야 한다. 그리고, 수학식 1의 W는 도체선(10)의 가로 길이를 나타내고, H는 도체선(10)의 세로 길이를 나타내며, R은 도체선(10) 에지부의 라운드 길이를 나타낸다.3 is a cross-sectional view illustrating only the conductor wire of FIG. 2 separately. As shown, the conductor line 10 is formed in a rectangular shape, each edge portion is formed to be round, the following equation (1) should be satisfied.

표 1은 R값 변화에 따른 절연 피복층(20)의 코팅 편육도를 나타낸다. 상기 코팅 편육도는 도체선(10)에 코팅된 절연 피복층(20)의 두께편차를 나타내며, 값이 작을수록 좋다. 상기 코팅 편육도는 아래의 수학식 2에 의해 계산된다.Table 1 shows the coating knitting degree of the insulating coating layer 20 according to the R value change. The coating knitting degree represents a thickness deviation of the insulating coating layer 20 coated on the conductor wire 10, and the smaller the value, the better. The coating knitting degree is calculated by Equation 2 below.

Figure 112007093836774-pat00010
Figure 112007093836774-pat00010

(여기서, C는 코팅 편육도, F(max)는 코팅된 절연 피복층 중 가장 두꺼운 부분의 두께, F(min)은 코팅된 절연 피복층 중 가장 얇은 부분의 두께를 나타낸다.)(Where C is the coating knitting degree, F (max) is the thickness of the thickest portion of the coated insulation coating layer, and F (min) is the thickness of the thinnest portion of the coated insulation coating layer.)

상기 표 1을 참조하면, R값의 범위가 'H/7~4H/3'일 경우, 1.3 이하의 코팅 편육도를 갖는데, 이와 같은 코팅 편육도를 가진 에나멜 전선이 모터에 사용되었을 때 효율적인 성능을 나타냄을 알 수 있다. 또한, R값의 범위가 'H/7 이하'일 경우와 '4H/3 이상'일 경우 코팅 편육도는 각각 1.5 이상, 1.3 이상으로 R값의 범위가 'H/7~4H/3'일 경우보다 모터의 성능이 떨어짐을 알 수 있다.Referring to Table 1, when the R value range is 'H / 7 to 4H / 3', the coating knitting degree is 1.3 or less, and when the enameled wire having such coating knitting degree is used for the motor, it is effective. It can be seen that. In addition, when the R value range is 'H / 7 or less' and the '4H / 3 or more', the coating knitting degree is 1.5 or more and 1.3 or more, respectively, and the R value range is 'H / 7 to 4H / 3'. It can be seen that the performance of the motor is worse than in the case.
