이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

도 2에 도시된 바와 같이, 본 발명에 따른 코일저항기는 무유도 저항을 구현하기 위해 외주면에 다수의 톱니가 형성된 톱니애자(100)를 포함한다.As shown in FIG. 2, the coil resistor according to the present invention includes a tooth insulator 100 having a plurality of teeth formed on an outer circumferential surface thereof to implement an induction resistance.

상기 톱니애자(100)는 후술할 절연애자(300, 도 3 참조)와 동일한 절연 기능을 수행하며, 그 외주면에는 코일(200)이 감긴다.The tooth insulator 100 performs the same insulation function as the insulator 300 (see FIG. 3), which will be described later, and the coil 200 is wound around its outer circumferential surface.

이때, 코일(200)은 동선과 같은 선재를 나선모양으로 감은 것을 말하며, 보통 코일의 성질 정도는 헨리(Henry: H)로 나타낸다.In this case, the coil 200 refers to a wire wound like a copper wire in the shape of a spiral, and the degree of property of the coil is usually represented by Henry (H).

또한, 본 발명에 따른 코일저항기는 일종의 무유도 저항(noninductive resistance)을 구현함이 바람직한데, 이는 권선을 무유도 권선으로 하여 인덕턱스를 매우 적게 한 것이다.In addition, the coil resistor according to the present invention preferably implements a kind of noninductive resistance, which is a very low inductance using the winding as a non-inductive winding.

예컨대, 무유도 저항이란 사전적 의미로 인덕턴스가 전혀 없는 저항을 말하지만, 실제로 인덕턴스가 전혀 없는 저항은 얻을 수 없으므로 사실상 권선저항기, 즉 코일저항기에서의 무유도 저항은 인덕턴스를 최소화시킨 저항으로 이를테면, 탄소 피막 저항기나 솔리드 저항기 등을 들 수 있다.For example, inductive resistance refers to a resistor that has no inductance in a dictionary meaning, but in fact, a resistance without any inductance cannot be obtained, and thus, inductive resistance in a winding resistor, that is, a coil resistor, is a resistance that minimizes inductance. A film resistor, a solid resistor, etc. are mentioned.

그리고, 본 발명에서는 상기 코일(200)의 양단에 코일브라켓(210)이 형성되어 이를 직접 분리 고정할 수 있도록 구성된다.In the present invention, the coil bracket 210 is formed at both ends of the coil 200 and is configured to directly separate and fix it.

이 경우, 상기 코일브라켓(210)은 반드시 도시된 형상으로 국한될 필요는 없으며, 다양한 형태로 변형 가능하다.In this case, the coil bracket 210 is not necessarily limited to the illustrated shape, it can be modified in various forms.

한편, 도 3 및 도 4에 도시된 바와 같이, 상기 코일(200)이 고정되는 절연애자(300) 쪽에는 애자브라켓(310)이 구비된다.On the other hand, as shown in Figure 3 and 4, the insulator bracket 310 is provided on the side of the insulator 300 to which the coil 200 is fixed.

상기 애자브라켓(310)은 고정브라켓(320)에 의해 절연애자(300)에 견고히 고정되며, 상기 절연애자(300)는 기존과 같이 고정프레임(400)에 고정된다.The insulator bracket 310 is firmly fixed to the insulator 300 by the fixing bracket 320, and the insulator 300 is fixed to the fixing frame 400 as before.

여기에서, 상기 절연애자(300)는 기존처럼 세라믹 만으로 이루어지지 않고, 세라믹과 지르코늄(zirconium)이 혼합된 후 압축성형된 제품이 사용된다.Here, the insulator 300 is not made of only ceramics as in the prior art, and a product that is compression molded after mixing ceramics and zirconium is used.

이때, 상기 지르코늄은 그 산화물이 지르코니아가 사용됨이 더욱 바람직한데, 이는 굴절률이 크고 녹는점이 높아서 내식성이 크며, 물에 녹지 않고, 황산·플루오린화수소산에 녹고, 요업용으로 중요한 원료이며, 치과에서 사용하는 세락믹 재료 중 가장 강도가 높고 심미성이 뛰어나 치아를 대신하는 재료로도 이용되고 있음은 물론 급격한 온도의 변화에 견디므로 급열·급랭의 기구류(예를 들면, 도가니)에도 사용되기 때문이다.At this time, the zirconium oxide is more preferably zirconia is used, which has a high refractive index and high melting point, which is large corrosion resistance, insoluble in water, soluble in sulfuric acid, hydrofluoric acid, is an important raw material for ceramics, used in dentistry This is because it is used as a substitute material for teeth because of its high strength and excellent aesthetics, and it is also used for instruments (eg, crucibles) of rapid quenching and quenching because it withstands rapid temperature changes.

본 발명에서는 상기 절연애자(300)를 세라믹과 지르코니아로 구성하되, 세라믹 30~40중량%, 지르코니아를 60~70중량%로 구성하여 내열성, 내충격성 향상 및 강도 향상에 기여하도록 구성된다.In the present invention, the insulator 300 is composed of ceramic and zirconia, but is composed of 30 to 40% by weight of ceramic and 60 to 70% by weight of zirconia to contribute to heat resistance, impact resistance improvement and strength improvement.

아울러, 상기 톱니애자(100)도 상기 절연애자(300)와 동일 재질로 구성되면 더욱 좋다.In addition, the tooth insulator 100 may be further composed of the same material as the insulating insulator 300.

뿐만 아니라, 본 발명에서는 상기 고정프레임(400) 및 이를 지지하는 베이스(500)를 합성수지로 제조하여 무게를 가볍게 함으로써 취급이 용이하고, 설치작업시에도 안전사고의 위험을 줄이며, 안전성도 높일 수 있게 된다.In addition, in the present invention, the fixing frame 400 and the base 500 for supporting the same are made of synthetic resin, so that the weight is light and easy to handle, reducing the risk of safety accidents during installation work and increasing safety. do.

이러한 구조로 이루어진 본 발명은 다음과 같이 조립설치될 수 있다.The present invention made of such a structure can be assembled as follows.

먼저, 톱니애자(100)의 외주면에 본 발명에 따른 코일(200)이 권취된다.First, the coil 200 according to the present invention is wound on the outer circumferential surface of the tooth insulator 100.

이때, 코일(200)의 양단에는 코일브라켓(210)이 각각 형성되어 있고, 상기 코일(200)이 설치될 절연애자(300) 쪽에는 상기 코일브라켓(210)과 대응되는 애자브라케(310)이 구비되어 있으므로 이들을 서로 일치되게 배치한다.In this case, coil brackets 210 are formed at both ends of the coil 200, and the insulator brackets 310 corresponding to the coil brackets 210 are provided on the insulator 300 on which the coils 200 are to be installed. Since it is provided, they are arranged to match each other.

이렇게 하여, 코일브라켓(210)과 애자브라켓(310)이 일치되면 고정볼트(330)로 이들을 상호 체결 고정함으로써 코일(200) 및 상기 코일(200)이 감긴 톱니애자(100)를 절연애자(300)에 연결하게 되고, 그 상태에서 고정브라켓(320)으로 누른 후 절연애자(300)에 볼트고정함으로써 체결을 완료하게 된다.In this way, when the coil bracket 210 and the insulator bracket 310 coincide with each other, the coil 200 and the insulator 100 wound around the coil 200 are insulated from each other by fastening and fixing them with the fixing bolt 330. ), And the bolt is fixed to the insulator 300 by pressing the fixing bracket 320 in that state to complete the fastening.

특히, 본 발명에서는 톱니애자(100)를 비롯한 절연애자(300)가 새로운 성분조성에 의해 강도가 증가되고, 내열성, 내충격성도 향상된 소재로 이루어졌으므로 쉽게 파손되지 않아 절연파괴의 현상을 극소화시키며, 사용수명도 연장하는 효과를 얻을 수 있다.Particularly, in the present invention, the insulator 300 including the saw tooth insulator 100 is increased in strength by new composition, and is made of a material having improved heat resistance and impact resistance, so it is not easily broken, thereby minimizing the phenomenon of insulation breakdown. The effect of extending the lifespan can also be obtained.

또한, 상기 절연애자(300)는 고정프레임(400)에 고정되는데, 상기 고정프레임(400)도 기존과 달리 합성수지물로 제작됨으로써 중량을 줄여 사용상 편의성 및 시공성을 향상시킨다.In addition, the insulator 300 is fixed to the fixed frame 400, unlike the existing frame 400 is also made of synthetic resin to reduce the weight to improve the ease of use and workability.

나아가, 다수의 고정프레임(400)을 묶어 한 조를 이룰 경우 이를 지지하는 베이스(500)의 경우에도 기존과 달리 합성수지물로 제작함으로써 고정프레임(400)과 마찬가지의 효과를 얻을 수 있다.Furthermore, in the case of forming a pair by tying a plurality of fixed frames 400, the base 500 supporting the same may be manufactured by using a synthetic resin, unlike the conventional frame 500, thereby obtaining the same effect as the fixed frame 400.
