이하에서 첨부한 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 발명에 따른 저항기의 사시도로서, 제1(a)도는 전면도이고 제1(b)도는 배면도를 나타낸다. 본 발명의 저항체(2)는 산화물반도체 세라믹스로 이루어진 정의 온도계수 즉, PCT(Posifive Temperature Coefficient)소자이다. 이 PCT소자는 BaT : O3를 주체로 해서 미량의 탄탄(Lanthan : La)족 이온(Ion) 또는 안티몬(Anfimon : sb)을 첨가해서 얻는 소결체이다.1 is a perspective view of a resistor according to the present invention, in which FIG. 1 (a) is a front view and FIG. 1 (b) is a rear view. The resistor 2 of the present invention is a positive temperature coefficient made of oxide semiconductor ceramics, that is, a PCT (Posifive Temperature Coefficient) element. This PCT element is a sintered body obtained by adding a trace amount of Tantan (La) group ion (Ion) or antimony (sb) mainly using BaT: O 3 .
이와 같은 PCT소자는 퀴리온도(Curie Temperafure)에서 저항이 급격히 증가하므로 전류억제기능을 구비하고 있음은 물론 저항체가 일정온도 이상의 상승하지 않음으로써 단락부를 별도로 구성할 필요가 없게된다.Since the PCT device has a rapid increase in resistance at Curie Temperafure, the PCT device not only has a current suppression function but also does not require a separate short circuit because the resistor does not rise above a certain temperature.
이와 같은 저항체(2)의 양면위에는 각각 서로 다른 저항값을 갖도록 서로 다른 면적으로 다수의 전극들(3A∼3D)이 코팅된다. 이 전극들은 은(Silver)으로 코-팅함이 바람직하다.On both surfaces of the resistor 2, a plurality of electrodes 3A to 3D are coated with different areas so as to have different resistance values. These electrodes are preferably coated with silver.
제2도는 제1(a)도에 도시한 Ⅰ-Ⅰ선을 따라 절단한 절단면도로서, 본 발명에 따른 저항기(1)의 구성에 대한 이해를 돕기 위해 도시하였다. 제1도와 동일한 부분에 대해서 동일한 도면부호를 부여하였으므로 더 이상의 설명은 불필요한 것이라 인정된다.FIG. 2 is a cross-sectional view taken along the line I-I shown in FIG. 1 (a), and is shown to help understand the structure of the resistor 1 according to the present invention. Since the same reference numerals are given to the same parts as in FIG. 1, further explanation is considered unnecessary.
제3도는 본 발명에 따른 저항기장치의 분해사시도이다. 제1도에 도시한 바와 같은 저항기(1)의 양면에는 다수의 전극들(3A∼3D)과 같은 수의 단자판들(4A∼4D)이 배치된다. 이 단자판들(4A∼4D) 각각은 대응하는 전극과 전기적으로 접속되고, 대략 대응하는 전극면적과 충분히 접촉할 수 있는 면적의 향상을 갖는 접촉부와 이 접촉부로부터 일체로 성형되어 하우징(5)에 형성된 단자수용구멍(7A∼7D)에 삽입하기 위한 삽입부로 구성되며, 각 단자판은 서로 이격되어 설치된다. 이 단자판들(4A∼4D)의 외측방향으로는 한쌍의 방열판(9A,9B)이 조립되고, 단자판들과 한쌍의 방열판 사이에는 각각 한쌍의 절연시-트(10A,10D)가 위치한다. 또한 하우징(5)은 상면에 한쌍의 돌조(11A,11B)가 형성되어 있고, 배면의 소켓(13)으로 단자판들(4A∼4D)의 각 삽입부가 삽입되도록 단자수용구멍(7A∼7D)이 형성되어 있다. 한쌍의 돌조(11A,11B)는 상기에 언급한 저항기(1)의 주변요소들을 일체로 결합하여 수용할 수 있도록 서로 마주보는 방향으로 대략 ㄷ 형상의 개방부가 형성되어져 있다. 미 설명부호 13A 내지 13D는 저항기(1)의 주변구성요소들을 일체로 체결하기 위한 체결구로서 끝을 절곡함에 의해 체결한다. 이와 같은 체결구를 형성하지 아니하고 리벳에 의해 체결할 수도 있다.3 is an exploded perspective view of a resistor device according to the present invention. On both sides of the resistor 1 as shown in FIG. 1, the same number of terminal plates 4A to 4D as the plurality of electrodes 3A to 3D are arranged. Each of these terminal plates 4A to 4D is electrically connected to a corresponding electrode, and integrally formed from the contact portion and formed in the housing 5 with a contact portion having an improvement in the area that can be sufficiently in contact with the corresponding electrode area. It consists of an insertion part for inserting into terminal accommodation hole 7A-7D, and each terminal board is mutually spaced apart. A pair of heat sinks 9A and 9B are assembled in the outward direction of these terminal plates 4A to 4D, and a pair of insulation sheets 10A and 10D are positioned between the terminal plates and the pair of heat sinks, respectively. In addition, the housing 5 has a pair of protrusions 11A and 11B formed on an upper surface thereof, and terminal receiving holes 7A to 7D are formed so that respective insertion portions of the terminal plates 4A to 4D are inserted into the rear sockets 13. Formed. The pair of protrusions 11A and 11B is formed with an approximately c-shaped opening in a direction facing each other so that the peripheral elements of the resistor 1 mentioned above can be integrally combined and accommodated. Reference numerals 13A to 13D are fastened by bending the ends as fasteners for integrally fastening the peripheral components of the resistor 1. It may be fastened by rivets without forming such fasteners.
이상과 같이 구성된 본 발명의 저항기장치는 저항기(1)의 주변구성요소들을 일체로 하여 단자판들(4A∼4D)의 각 삽입부를 하우징(5)의 단자수용구멍(7A∼7D)에 삽입하고, 방열판(9A,9B)의 하단 양 모서리부를 하우징(5)에 형성된 돌조(11A,11B)의 개발부에 삽입 고정함으로서 조립된다.In the resistor device of the present invention configured as described above, the peripheral components of the resistor 1 are integrally inserted into respective insertion portions of the terminal plates 4A to 4D into the terminal receiving holes 7A to 7D of the housing 5, Both lower ends of the heat sinks 9A and 9B are assembled by inserting and fixing the developing portions of the protrusions 11A and 11B formed in the housing 5.
이상에서 설명한 바와 같이, 본 발명에 따른 저항기 및 이 저항기를 이용한 저항기장치는 콤팩트한 구성을 가지므로 부피가 소형화되어, 이 장치가 자동차 에어콘디셔너의 송풍구 내벽에 설치된다는 점을 고려할 때 풍량의 감소나 풍력의 저하를 방지할 수 있고, 공정이 간소화되어 생산단가를 절감할 수 있을 뿐 아니라 별도의 단락수단을 설치할 필요가 없는 우수한 효과가 있는 것이다.As described above, the resistor according to the present invention and the resistor device using the resistor have a compact configuration, so that the volume is reduced, so that the air volume is reduced in consideration of the fact that the device is installed on the inner wall of the air vent of the automobile air conditioner. The reduction of wind power can be prevented, the process is simplified, and the production cost can be reduced, and there is no need to install a separate short circuit means.
