* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 검지부 2 : 절연판(기판)1: detection part 2: insulation plate (substrate)
3 : 박막 NTC 4 : 발열체3: thin film NTC 4: heating element
본 고안은 가정용, 산업용 또는 자동차등의 연료탱크내의 액위를 감지할 수 있도록한 박막 NTC를 이용한 액위감지 장치에 관한 것으로서, 특히 연료탱크내의 액위를 계절에 관계없이 항상 정확하게 감지할 수 있도록 한 것이다.The present invention relates to a liquid level sensing device using a thin film NTC that can detect the liquid level in the fuel tank of the home, industrial or automobile, in particular, it is possible to always accurately detect the liquid level in the fuel tank regardless of the season.
종래의 액위감지 장치는 제1도에서와 같이 연료탱크(110)내에 회전축(102)을 중심으로 일측에는 부구(103)를 설치하고, 액위변화에 따른 부구(103)의 변화에 의해 접촉단자(101)와 상하 가변저항(105)이 가변적으로 접촉할 수 있게 구성되었다.In the conventional liquid level sensing device, as shown in FIG. 1, a float 103 is installed at one side of the fuel tank 110 about the rotational shaft 102, and the contact terminal (3) is changed by the change of the float 103 according to the liquid level change. 101 and the up and down variable resistor 105 are configured to be in variable contact with each other.
이와같이 구성된 종래의 액위감지 장치는 전원을 공급한 후 연료탱크(110)내에 연료를 주입하면 연료의 양에 의하여 부구(103)의 위치가 상하로 유동된다.In the conventional liquid level sensing device configured as described above, when fuel is injected into the fuel tank 110 after the power is supplied, the position of the buoy 103 flows up and down by the amount of fuel.
상기 부구(103)의 유동에 따라 부구(103)의 아암과 연결된 접촉단자(101)는 가변저항(105)에 접촉되는 부분이 변화되면서 가변저항(105)의 저항값이 변화되어 전류변환기를 통해 연료계기판에 유량이 나타나도록 하는 것이다.According to the flow of the float 103, the contact terminal 101 connected to the arm of the float 103 is changed in contact with the variable resistor 105, the resistance value of the variable resistor 105 is changed through the current converter The flow rate is displayed on the fuel gauge substrate.
그러나, 상기와 같이 부구(103)의 유동됨에 따라 가변저항(105)이 유량값을 나타내므로서, 유동시 부구(103)의 유동에 의해 연료계기판에 지시되는 지침바늘이 유동되어 정확한 유량을 감지할 수 없을 뿐 아니라 접촉불량에 의한 정확한 측정이 이루어지지 않아 오동작의 빈번한 결점이 있었으며, 구조가 복잡해져 제품의 원가 상승 요인이 되는 문제점등이 야기되었다.However, as the variable resistor 105 exhibits a flow rate value as the float 103 flows as described above, the guide needle instructed on the fuel gauge substrate flows by the flow of the float 103 to detect an accurate flow rate. In addition, there was a frequent defect of malfunction due to inaccurate measurement due to poor contact, and the structure was complicated, causing problems such as cost increase of the product.
본 고안은 상기한 종래의 제결점 및 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 그 목적은 검지부를 절연판(기판) 일측에는 전극 및 NTC 박막을 연결하고, 타측에는 발열체를 박판화 시켜 계절에 따라 일정한 온도를 유지시켜 온도변화에 무관하게 정확한 연료량을 감지할 수 있고, 검지부의 간소화로 제작이 용이함은 물론 설치를 용이하게 하여 제조단가 및 설치비를 절감토록 한 것이 그 특징이다.The present invention is devised to solve the above-described conventional drawbacks and problems, the object of the present invention is to connect the electrode and NTC thin film on one side of the insulating plate (substrate), the other side by thinning the heating element according to the season By maintaining a constant temperature, it is possible to detect the exact amount of fuel irrespective of the temperature change, and it is easy to manufacture by simplifying the detection unit, and it is easy to install, thereby reducing the manufacturing cost and installation cost.
상기의 목적을 달성할 수 있는 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When the present invention to achieve the above object will be described in detail by the accompanying drawings as follows.
제2도에서와 같이 1은 연료탱크내의 연료를 감지할 수 있도록 한 검지부이다.As shown in FIG. 2, 1 is a detection unit capable of detecting fuel in the fuel tank.
이 검지부(1)는 절연판(2) 일측에 일정한 간격이 유지되게 전극과 박막 NTC (3)을 배열하여 연결한다.The detection unit 1 arranges and connects the electrodes and the thin film NTC 3 so that a constant distance is maintained on one side of the insulating plate 2.
그리고, 상기 박막 NTC (3) 타측에는 일정한 온도를 유기시킬 수 있도록 발열체(4)를 박막화시켜 구성된 것이다.On the other side of the thin film NTC 3, the heating element 4 is thinned so as to induce a constant temperature.
미설명부호 10은 케이스(Case)이고, 11은 결착전극부이다.Reference numeral 10 denotes a case, and 11 denotes a binding electrode part.
이와같이 구성된 본 고안은 절연판(2) 일측의 전극과 박막 NTC (3)을 배열하고, 타측에는 발열체(4)를 박막화 시킨 검지부(1)를 제3도에서와 같이 케이스(10)의 결착전극부(11)에 꽂아 설치한 다음 상기 연결된 전극 및 박막 NTC를 전류계(미도시함)와 도통되게 연결하여 연료계기판에 접속연결한다.According to the present invention configured as described above, the electrode 1 of the insulating plate 2 and the thin film NTC 3 are arranged, and on the other side, the detection unit 1 in which the heating element 4 is thinned, as shown in FIG. (11), and then connected to the fuel gauge substrate by connecting the connected electrode and the thin film NTC conductively with an ammeter (not shown).
상기와 같이 장착하여 전원을 공급한 후 연료탱크 내에 연료를 공급하면, 검지부(1)의 절연판(2) 일측에 연결된 전극 및 박막 NTC (3)의 침전됨에 의해 변화되는 박막 NTC의 자체저항 값에 의해 액위를 측정할 수 있는 것이다.When the fuel is supplied to the fuel tank after mounting and supplying power as described above, the electrode connected to one side of the insulating plate 2 of the detector 1 and the self-resistance value of the thin film NTC changed by the precipitation of the thin film NTC (3). The liquid level can be measured by
이때, 상기 검기부(1)는 절연판(2) 타측에 박막화된 발열체(4)가 셋팅된 온도로 발열되어 온도를 일정하게 유지시키므로 계절에 관계없이 연료의 감지를 정확하게 측정할 수 있게 되는 것이다.At this time, the detector 1 is heated to the temperature set by the heating element 4 thin filmed on the other side of the insulating plate 2, so that the temperature is kept constant so that the detection of the fuel can be accurately measured regardless of the season.
이상 설명한 바와같이 검지부를 절연기판 일측에 박막 NTC와 이를 연결하는 전극들을 박막화시키므로써, 전극에 의해 연료탱크내의 연료를 정확하게 측정할 수 있음과 동시에 발열체에 의해 계절에 관계없이 연료를 정확하게 측정할 수 있고, 구조가 간소화되어 제작공정이 간소화로 인한 제작비 절감 및 설치가 간편용이하며, 불량율이 전혀 없게 되는 매우 유용한 고안이다.As described above, by thinning the thin film NTC and the electrodes connecting the thin film NTC to one side of the insulating substrate, the fuel can be accurately measured in the fuel tank by the electrode and the fuel can be accurately measured regardless of the season by the heating element. In addition, the structure is simplified, the manufacturing process is reduced and the installation is easy due to the simplified manufacturing process, it is a very useful design that there is no defect rate at all.
