It is used in display elements.
상기한 바와 같은 액정은 원하는 특성의 배합상태등을 알기 위하여서는 반드시 저항을 측정하여 액정의 특성을 검사하게 된다.The liquid crystal as described above is to measure the resistance of the liquid crystal by measuring the resistance in order to know the blending state of the desired characteristics.
종래에 이러한 액정의 저항을 측정하는 방식은 외부전극이 연결되는 용기내에 액정을 담고, 내부전극을 연결하는 저항을 측정하도록 하고 있으나, 이는 상기한 바와 같은 저계나 자계 또는 온도등에 따라 변화하는 액정 고유의 성질에 따라 불안정된 상태에서 측정을 하게 되므로 그 측정치에 대한 신뢰도를 떨어뜨리고 액정의 교환이 용이하지 못하다는 문제점이 있다.Conventionally, the method of measuring the resistance of the liquid crystal is to contain the liquid crystal in the container to which the external electrode is connected, and to measure the resistance connecting the internal electrode, but this is inherent in the liquid crystal that changes according to the low field, magnetic field or temperature as described above Since the measurement is performed in an unstable state depending on the property of the, there is a problem that the reliability of the measured value is lowered and the liquid crystal is not easily exchanged.
본 고안은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 안정된 상태에서 저항을 측정함으로써, 측정값의 신뢰도를 높이고, 시료인 액정의 교환을 용이토록 한 액정의 저항 측정장치를 제공하는데 있다.The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to improve the reliability of the measurement value by measuring the resistance in a stable state, and to facilitate the exchange of the liquid crystal as a sample To provide a resistance measuring device.
상기한 바와 같은 목적을 달성하기 위하여 본 고안은 내부에 형성된 순환통로에 유입구 및 유출구가 연통됨과 아울러 내측중앙에는 걸림턱을 갖는 삽입홈이 형성된 홀더와, 내측에 액정수용부를 갖고 상기 홀더의 삽입홈에 안착되는 용기와 내측에 전극삽입홈을 갖고 그 외측에 절연부가 형성됨과 아울러 하단에 측정바아를 작고 용기내에 삽입 설치되는 내부전극으로 구성되는 액정의 저항 측정장치를 제공한다.In order to achieve the object described above, the present invention has an inlet and an outlet communicating with a circulation passage formed therein, and a holder having an insertion groove having a locking jaw in the inner center thereof, and a liquid crystal accommodating portion therein. The present invention provides a resistance measuring device for a liquid crystal comprising a container seated on an inner side and an electrode insertion groove on an inner side thereof, and an insulating portion formed on an outer side thereof, and a measuring bar at a lower end thereof and an internal electrode inserted into the container.
이하에 본 고안의 바람직한 실시예를 첨부된 도면에 따라서 더욱 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안인 액정의 저항 측정장치를 나타내는 분해 사시도로서, 부호(1)은 홀더를 나타내고 있다.1 is an exploded perspective view showing a resistance measuring device of a liquid crystal according to the present invention, and reference numeral 1 denotes a holder.
상기한 홀더(1)의 내측에는 삽입홈(2)이 형성되어 있고, 그 외측의 위쪽에는 유입구(3)와 유출구(4)가 돌출 형성되어 내부와 연통되어 있으며, 그 아래쪽에는 외부전극이 삽입 연결 되도록 전극연결구(5)가 형성되어 있다.An insertion groove 2 is formed inside the holder 1, and an inlet 3 and an outlet 4 protrude from the outside of the holder 1 to communicate with the inside thereof. The electrode connector 5 is formed to be connected.
상기한 홀더(1)의 삽입홈(2)에는 내측에 액정수용부(6)가 형성되고 외측 상단에는 플랜지(7)가 형성된 용기(8)가 삽입되어진다.In the insertion groove 2 of the holder 1, a liquid crystal accommodating portion 6 is formed at an inner side thereof, and a container 8 having a flange 7 is inserted at an outer upper end thereof.
상기한 용기(8)의 액정 수용부(6)내에는 하단에 측정바아(9)를 갖는 내부전극(10)이 삽입되어 진다.In the liquid crystal accommodating portion 6 of the container 8, an internal electrode 10 having a measuring bar 9 is inserted at a lower end thereof.
상기 내부전극(10)은 내측 중앙에 전극삽입홈(11)이 형성되어 있고, 그 외측에는 절연부(12)가 형성되어 있다.The internal electrode 10 has an electrode insertion groove 11 formed at an inner center thereof, and an insulating portion 12 formed at an outer side thereof.
상기 절연부(12)는 테프론(Tefion)등의 절연재료로 형성하는 것이 바람직하다.The insulating portion 12 is preferably formed of an insulating material such as Teflon (Tefion).
상기한 용기(8)와 내부전극(10)의 상면에는 통기공(13) (13')이 각각 뚫어져 있다.Vent holes 13 and 13 'are respectively drilled on the upper surface of the container 8 and the internal electrode 10.
제2도는 본 고안의 결합상태를 나타내기 위한 단면도로서, 홀더(1)의 내부에는 유입구(3) 및 유출구(4)가 연통된 순환통로(14)가 형성되어 별도의 항온탱크(T)에 의해 항온수(W)가 순환하게 되어 있다.Figure 2 is a cross-sectional view for showing a coupling state of the present invention, the inlet 3 and the outlet 4 is formed in the circulation passage 14 in communication with the inside of the holder 1 is formed in a separate constant temperature tank (T) Constant temperature water W circulates by this.
상기한 홀더(1)의 삽입홈(2)에는 걸림턱(15)이 형성되어 상기한 용기(8)의 플랜지(7)가 안착되어 있다.A locking jaw 15 is formed in the insertion groove 2 of the holder 1 so that the flange 7 of the container 8 is seated.
상기 용기(8)의 액정수용부(6)에는 시료인 액정(L)이 수용되고, 측정바아(9)가 접촉되어 있다.The liquid crystal L which is a sample is accommodated in the liquid crystal accommodating part 6 of the said container 8, and the measurement bar 9 is in contact.
상기한 바와 같이 구성되는 본 고안 액정의 저항 측정장치는 액정의 저항을 측정함에 있어서는, 먼저 용기(8)를 아세톤등의 세정제를 사용하여 깨끗하게 세정한후 홀더(1)의 삽입홈(2)에 삽입하고 그 내부에 내부전극(10)을 장착한 후 외부전극도 연결한다.In measuring the resistance of the liquid crystal of the present invention, the resistance measuring device of the present invention, configured as described above, first cleans the container 8 by using a detergent such as acetone, and then inserts it into the insertion groove 2 of the holder 1. Insert and mount the inner electrode 10 therein and then connect the outer electrode.
그러면, 걸림턱(15)에 용기(8)이 플랜지(7)가 안착 되는데 그 후, 항온탱크(T)를 작동시켜 측정온도 조건에 맞는 온도로 조절된 항온수(W)를 순환통로(14) 내로 순환 시킨다.Then, the flange 8 of the container 8 is seated on the catching jaw 15, and then, the constant temperature water W adjusted to a temperature corresponding to the measurement temperature condition by operating the constant temperature tank T is circulated. Circulate inside).
이때, 외부전극 역할을 하는 홀더(1)와 내부전극(10)이 열적 평형상태에 도달할 때까지 상기한 항온수(W)를 충분히 순환시킨 후, 양 전극이 열적 평형상태에 도달하게 되면 내부전극(10)을 들어내고 상기 용기(8)의 액정수용부(6)내에 약 1ml의 액정을 떨어뜨린 후 내부전극(10)을 삽입하면 별도로 장치된 저항측정계(M)에 저항값이 나타난다.At this time, after sufficiently circulating the above-mentioned constant temperature water (W) until the holder 1 and the internal electrode 10 serving as the external electrode reach the thermal equilibrium state, when both electrodes reach the thermal equilibrium state, the internal When the electrode 10 is lifted out, about 1 ml of liquid crystal is dropped into the liquid crystal accommodating part 6 of the container 8, and the internal electrode 10 is inserted, the resistance value is displayed on the resistance meter M separately installed.
또, 내부전극(10)에 절연재를 형성시키므로서 전기적으로 쇼트되는 현상은 방지된다.In addition, the electrical short is prevented by forming an insulating material on the internal electrode 10.
일반적으로 고정항값을 나타내는 액정은 외부환경에 매우 민감하므로 10회 이상을 일정한 간격을 두고 측정하여 평균값을 취하면 측정하고자 하는 액정의 저항값은 매우 높은 신뢰도를 갖게 된다.In general, since the liquid crystal exhibiting a fixed term value is very sensitive to the external environment, if the average value is taken by measuring at least 10 times at regular intervals, the resistance value of the liquid crystal to be measured has a very high reliability.
그리고, 액정(L)을 교환할 때 용기(8)와 내부전극(10)을 홀더(1)로부터 빼내게 되는데, 이때 통기공(13) (13')으로 공기가 유입되기 때문에 용이하게 분리할 수 있다.7In addition, when the liquid crystal L is replaced, the container 8 and the internal electrode 10 are removed from the holder 1, and at this time, air is introduced into the air vents 13 and 13 'so that the liquid can be easily separated. May 7
이와같은 본 고안 액정의 저항 측정 장치는 항상 안정된 상태에서 액정의 저항 측정하게 되어 신속하고 정확한 측정이 가능하고, 액정뿐만 아니라 유동성 물질등의 측정에도 신뢰도를 향상시키는 이점이 있다.The resistance measuring device of the present invention liquid crystal is always the stable measurement of the resistance of the liquid crystal in a stable state it is possible to measure quickly and accurately, there is an advantage to improve the reliability in the measurement of not only liquid crystal, but also a fluid.
