본 고안은 저압코일 권선용보빈과 고압코일 권선용보빈이 동일축상에 위치되어 있는 플라이백트랜스포머에 관한 것으로, 특히 고압코일의 보빈에 절연수지 합침율을 향상시키기 위하여 관통홈을 형성시킨 플라이백 트랜스포머에 관한 것이다.The present invention relates to a flyback transformer in which a bobbin for a low pressure coil winding and a bobbin for a high pressure coil winding are positioned on the same axis. will be.
종래의 플라이백 트랜스포머(Flyback Transformer, 이하 ″FBT″로 약칭함)에서는 고압코일 권선용보빈의 단면이 제3도에 도시한 바와 같이, U자형홈을 형성하고 있어서 이 사이에 지름이 0.04-0.08mm정도인 극세선코일을 200-300회 권선시켜 놓은후 절연수지물을 주입시켜 이 절연수지물이 코일사이로 스며들게하여 고압방전등으로 부터 코일과 회로를 보호하도록 되어 있었다.In the conventional flyback transformer (hereinafter abbreviated as "FBT"), the cross section of the bobbin for winding a high pressure coil forms a U-shaped groove as shown in FIG. 3, and the diameter is 0.04-0.08mm between them. After winding about 200-300 times of fine wire coils, the insulation resin was injected to infiltrate between the coils to protect the coils and circuits from high-pressure discharge lamps.
그러나 FBT의 고압코일사이에 절연수지물을 주입시키도록 되어있는 종래의 FBT에서는, 코일권선부의 단면이 U자홈으로 형성되어 있고, 이사이에 코일을 감은후 절연수지물을 상기 코일상에 주입하도록 되어 있기때문에, 코일사이사이에 절연수지물이 충분히 스며들기가 어렵고, 이로인하여 코일사이에 절연수지물이 충진되지 않은부분(void)이 발생하게 되므로서 고압방전등에 의해 회로의 신뢰성에 치명적인 영향을 주어 왔었다. 더구나 종래의 코일보빈에 있어서 코일보빈 격막에 코일권선을 구별짓기위한 凹홈을 형성시키거나 O형구멍을 형성시키는 것은 격막이 극히 얇기 때문에 (0.55-0.8mm) 또 다시 凹홈을 형성시키기가 어렵고, O형구멍을 형성시킴에 있어서는 사출금형제작상 상하 격막에만 설치가 가능하기 때문에 주로 권선이 많이 되는 격막의 측면부에 금형을 설치하기가 곤란하여 실제의 합침을 개선에는 크게 기여치 못했었다.However, in the conventional FBT in which the insulating resin is injected between the high-pressure coils of the FBT, the end face of the coil winding is formed with a U-shaped groove, and the insulating resin is injected onto the coil after the coil is wound around the moving coil. Therefore, it is difficult to sufficiently insulate the insulating resin between the coils, which causes a void in which the insulating resin is not filled between the coils, thereby causing a fatal effect on the reliability of the circuit by a high-voltage discharge lamp. Came. Moreover, in the conventional coil bobbin, it is difficult to form the groove in the coil bobbin diaphragm to form the groove for distinguishing the coil winding or to form the O-shaped hole because the membrane is extremely thin (0.55-0.8mm). In the case of forming the O-shaped hole, it is possible to install only the upper and lower diaphragms in the manufacture of injection molds, so that it is difficult to install a mold on the side of the diaphragm where the winding is large.
이에 본 고안에서는 FBT제조시에 합침율을 향상시키므로서 종래의 FBT가 지니는 보이드에 의한 문제점을 개선하고자, 고압코일 권선용보빈 밑변에 절연수지물 주입용의 관통구멍을 형성시켜서 절연수지불이 각각의 권선코일 사이사이에 잘 스며들도록 한 FBT를 제공함에 그 목적이 있는 것으로서, 이하 첨부된 예시도면과 함께 본 고안의 구성 및 작용효과를 상세히 설명하면 다음과 같다.Therefore, in the present invention, in order to solve the problems caused by the voids of the conventional FBT by improving the incorporation rate at the time of manufacturing FBT, the insulating resin payment is formed by forming a through-hole for insulating resin injection at the bottom of the bobbin for high pressure coil winding The purpose of the present invention is to provide an FBT that is well permeated between the winding coils. Hereinafter, the configuration and the effect of the present invention will be described in detail with the accompanying drawings.
본 고안은 동일축 (1) 상에 설치된 저압코일 권선용보빈(2)과 고압코일 권선용보빈(3) 및 고정판(4)으로 구성된 플라이백 트랜스포머에 있어서, 상기 고압코일 권선용보빈(3)의 격막(5)과 격막(5)사이, 즉 코일(6)이 감겨지는 격막(5)사이의 밑면(7)에 여러개의 관통홈(8)을 형성시킨 구조로 되어 있다.The present invention is a flyback transformer composed of a low pressure coil winding bobbin (2), a high pressure coil winding bobbin (3) and a fixed plate (4) installed on the same shaft (1), the diaphragm of the high pressure coil winding bobbin (3) A plurality of through grooves 8 are formed in the bottom surface 7 between 5) and the diaphragm 5, that is, between the diaphragm 5 on which the coil 6 is wound.
따라서 저압코일 권선용보빈(2)과 고압코일 권선용보빈(3), 그리고 고정판 (4)을 축(1)상에 결합시킨 후 관통홈(8)을 통해 코일(6)사이에 절연수지물을 주입시키면 지름이 0.04-0.08mm인 코일의 사이사이로 절연수지물이 균일하고 확실하게 주입되게 되어져 종래에 야기되던 보이드(Void)등의 형성에 대한 문제점을 해결할 수가 있는 것이다.Therefore, after coupling the low pressure coil winding bobbin (2), the high pressure coil winding bobbin (3), and the fixed plate (4) on the shaft (1), insulated resin is injected between the coil (6) through the through groove (8). In this case, the insulation resin is uniformly and reliably injected between the coils having a diameter of 0.04-0.08 mm, thereby solving the problem of the formation of voids, which have conventionally occurred.
즉 보빈의 밑면(7)에 맞닿은 부분의 코일에는 절연수지물이 주입되기 곤란했던 종래의 단점을 이 밑면(7)에 다수개의 관통홈(8)을 형성시키므로서 절연수지물이 코일전체의 상하면에 고르게 분포 주입되도록 하므로서 절연효과를 상승시키는 것이다.In other words, the insulation of the upper and lower surfaces of the entire coil is formed by forming a plurality of through grooves 8 on the bottom 7 of the conventional disadvantage that the insulation of the coil which is in contact with the bottom 7 of the bobbin is difficult to inject. It is to increase the insulation effect by allowing evenly distributed injection.
이상의 설명에서와 같이 본 고안에 따라 고압코일 권선용보빈의 밑면(7)에 관통홈(8)을 형성시키므로서, 코일사이에 절연수지물이 충진되지 않은부분(Void)이 없어지게 되므로 부품의 신뢰성을 극대화시킬 수 있고, 기존의 고압코일 권선용보빈에 절연수지물이 주입되는 구멍을 뚫기만하면 되므로 제작이 간단하여, 고압방전등에 의한 회로상의 불합리한 점을 개선시킬 수 있는 등의 효과를 얻게 된다.As described above, by forming the through groove 8 in the bottom surface 7 of the bobbin for high-pressure coil winding according to the present invention, there is no void (Void) between the coil is not filled between parts reliability It is possible to maximize the, and simply by drilling a hole in which the insulation resin is injected into the existing high-pressure coil winding bobbin, the production is simple, and the effect of improving the circuit irrationality by the high-pressure discharge lamp is obtained.
