본 발명은 가융 와이어 권취저항(Fusible Wire Wound Resistor)에 관한 것으로, 휴대폰 충전기, 각종 충전기의 휴즈저항으로 사용시에 규격이상의 과부하가 발생하거나 다른 부품에 이상이 생기게 되면 선이 단선되어 회로를 단락(短絡)시키는 휴즈역할을 함으로써, 과부하로 인한 화재의 위험성이 없이 안전하게 사용할 수 있도록 한 것이다.BACKGROUND OF THE
종래에 일반적으로 사용되는 와이어 권취저항(Wire Wound Resistor)은 와이어가 세라믹 막대의 전체간격(T)으로 권취되어 형성된 것으로 전압,전류의 동요가 안정적이다.The wire wound resistor generally used is formed by winding the wire at the entire interval T of the ceramic rod, and the fluctuation of voltage and current is stable.
그러나, 와이어에 과전압이나 과전류가 흐를 때, 발열을 하게 되며, 상기 발열에 의해 와이어가 단선이 되어야 하는데 종래의 와이어는 세라믹 막대의 둘레로 전체적으로 균등하게 권취되어 있어 열이 분산되어 발산하게 되어 와이어가 단선되지 않는 결점이 있다.However, when an overvoltage or overcurrent flows through the wire, heat is generated, and the wire must be disconnected by the heat generation. The conventional wire is wound around the ceramic rod as a whole, so that heat is dispersed and dissipated. There is a defect that does not break.
또, 규격이상의 과부하(Overload)가 되어도 와이어가 단락되지 않고, 계속적으로 발열이 되어 화재의 위험성이 있는 결점이 있었다.In addition, even if the overload exceeds the specification, the wire is not short-circuited.
본 발명은 종래의 결점을 해결하기 위하여 세라믹 막대의 양단부에 캡이 착지되어 페인트가 피착되는 세라믹 막대의 중앙부로 실리콘도료를 도포하여 와이어를 집중시켜 권취하되, 상기 와이어의 권취간격과 길이 및 피치상태를 최적의 유효길이와 유효피치로 하며, 또한 세라믹 막대의 성분을 한정함과 캡을 최적의 유효길이(높이)로 결합구성하여 발열로 인한 전압,전류의 과부하시 선이 단락되어 전원을 효과적으로 차단하는 퓨즈기능을 발휘할 수 있도록 함에 목적이 있다.In order to solve the drawbacks of the present invention, a cap is landed at both ends of a ceramic rod and a silicone coating is applied to a central portion of a ceramic rod to which paint is deposited, thereby concentrating the wire, winding intervals, lengths, and pitch states of the wire. The optimum effective length and effective pitch are also defined, and the components of the ceramic bar are limited and the cap is combined with the optimum effective length (height) to cut off the power supply effectively due to the short-circuit of the voltage and current due to heat generation. The purpose is to enable the fuse function to be performed.
이하, 첨부된 도면을 참고하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings in detail as follows.
도1에 나타낸 바와 같이, 세라믹 막대(1)의 전체간격(Full Pich)(T)에 와이어(5)를 균일하게 권취하여 세라믹 막대(1)의 양단부에 착지시킨 캡(2)(2a)에 리드와이어(3)(3a)를 접지하여 인출된 둘레부에 페인트(4)를 피착시켜 구성된 것에 있어서,As shown in Fig. 1, the
상기 세라믹 막대(1)의 중앙부로 실리콘도료(6)를 도포한 후, 상기 실리콘도료(6)의 둘레 중앙부로 집중시켜 권취하되, 상기 와이어(5)가 권취되는 권취간격(Winding Pich)(t)을 1.0㎜~2.5mm이내로 하는 세라믹 막대(1)의 유효길이의 0%초과, 50%이하로 권취하여 줌으로써, 과부하(Overload)가 발생시에 단락(短絡)을 안정적으로 함을 특징으로 한다.After coating the silicone paint (6) to the center of the ceramic rod (1), it is concentrated and wound around the central portion of the silicone paint (6), winding winding (Winding Pich) winding the wire (5) (t It is characterized in that a short circuit is stable at the time of overload when the coil is wound to more than 0% and 50% or less of the effective length of the
또한, 상기 세라믹 막대(1)의 성분은 산화알루미늄(Al2O3) 55%미만이며, 캡 (2)(2a)의 유효길이(높이)가 2.0mm이상으로 한 와이어(5)의 재질 성분에 망간(Mn), 니켈(Ni)을 포함하도록 하였다.Further, the component of the
이와 같이 구성된 본 발명은 사용시에 전기가 선을 통하여 흐르면서 이상 전기의 흐름에서 과도한 열이 발생하게 되는데, 이때 선의 전체간격(Pull Pich)(T) 즉, 선의 간격이 넓으면 열이 분산되어 단락(短絡)이 불량하게 되고, 이와 반대로 선의 간격 즉, 권취간격(t)이 일정한 간격으로 좁으면, 과부하(Overload)등의 이상 전기의 흐름으로 발열이 일시적으로 중앙부에 집중되어 단락(短絡)되므로써 휴즈의 역할을 하게되어 화재발생의 위험이 없게 된다.The present invention configured as described above causes excessive heat in the flow of abnormal electricity as electricity flows through the line during use, wherein a wide gap (T) of the line, that is, a wide line of the line, causes heat to be dispersed and short-circuited (短 絡) becomes poor and, on the contrary, if the line interval, i.e., the winding interval t is narrow at a constant interval, the heat is temporarily concentrated in the center due to abnormal electric flow such as overload, causing the fuse to be shorted. There is no risk of fire.
상기의 세라믹 막대(1)의 둘레부로 도포된 실리콘도료(6)는 와이어(5)의 발열시에 열전도를 늦게 함은 물론 실리콘도료(6)가 물러져서 권취된 와이어(5)가 튀는 것을 방지하고, 선과 선끼리 붙는 현상(Short현상)을 없애준다.The
도2는 본 발명에 따른 다른 실시예를 보인 것으로, 상기 세라믹 막대(1)의 중앙부로 와이어(5)를 집중시켜 권취한 것을 특징으로 한다.Figure 2 shows another embodiment according to the present invention, characterized in that the
상기와 같이 권취되는 와이어(5)의 권취간격(Winding Pich)(t)을 1.0㎜~2.5mm이내로 하는 세라믹 막대(1)의 유효길이의 0%초과, 50%이하로 권취한다.Winding Pich (t) of the
상기와 같이 권취하여 줌으로써, 과부하(Overload)가 발생시에 세라믹 막대(1)의 중앙부로 집중적으로 열이 발생하여 빨리 단락(短絡)이 되도록 한다.By winding as described above, when overload occurs, heat is concentrated in the center of the
또, 세라믹 막대(1)의 성분이 산화알루미늄(Al2O3) 55%미만일 경우와 캡(2)(2a)의 유효길이(높이)가 2.0mm이상일 경우 및 와이어(5)의 재질 성분에 망간(Mn),니켈(Ni)이 포함될 경우에는 온도계수가 높아져 전류의 흐름을 막아 주는 저 항값을 상승시켜 와이어(5)에서 열이 점점 높게 발생하도록 하여 단선이 빨리 되도록 한다.(세라믹 함량이 높을수록 열전도가 빨라 단선이 늦어진다.)In addition, when the component of the
이와 같이 된 본 발명은 휴대폰 충전기 및 각종 충전기에 휴즈저항으로 사용시에 규격이상의 과부하가 발생하거나 다른 부품에 이상이 생기게 되면 선이 단선되어 회로를 단락(短絡)시키는 휴즈역할을 함으로써, 과부하로 인한 화재발생의 위험성을 방지하여 안전하게 사용할 수 있도록 한 효과가 있는 것이다. In the present invention as described above, when a cell phone charger and various chargers are used as a fuse resistor, when an overload occurs or a problem occurs in other parts, the wire is disconnected and the fuse acts as a short circuit. It is effective to prevent the risk of occurrence so that it can be used safely.
