Abstract

본 발명은 피측정 유체의 온도에 따라 수축 또는 팽창되는 형상기 억합금에 의해 내부에 배치된 접점을 가동시켜 그 접점과 연결되고 외부로 돌출된 단자를 전기적으로 연결 또는 차단시키는 형상기억합금을 이용한 수온수위치에 관한 것이다.The present invention utilizes a shape memory alloy that electrically connects or blocks a terminal that is connected to the contact and protrudes to the outside by operating a contact disposed therein by a shape retaining alloy that contracts or expands depending on the temperature of the fluid to be measured. It relates to the location of water temperature water.

그 장치는 피측정체에 장탈착 할 수 있도록 나사부(52) 및 육각너트부(53)가 형성되고, 외부실링(56)이 장착된 몸체; 몸체 상부에 접합되고, 내부에 기밀이 유지되는 중공부(中空部)가 형성된 감지부(51); 몸체 하부에 접합되고, 내부에 기밀이 유지되는 중공부 및 외부로 노출되는 단자(55)가 형성된 단자부(54); 피측정체의 온도를 감지하여 소정온도 범위 내에서 상승 하강 운동하는 스위치 수단; 그리고 단자부(54)의 내부에서 각 단자(55)와 연결되고, 스위치 수단의 상하운동에 따라 단자(55)를 전기적으로 연결 또는 차단시키는 가동접점(57) 및 고정접점(58)을 포함한다.The apparatus is provided with a threaded portion 52 and a hexagonal nut portion 53 so as to be detachably attached to the object to be measured, the outer sealing 56 is mounted body; A sensing unit 51 bonded to an upper portion of the body and having a hollow portion in which airtightness is maintained; A terminal portion 54 bonded to a lower portion of the body and having a hollow portion in which airtightness is maintained and a terminal 55 exposed to the outside; Switch means for sensing the temperature of the object to be measured to move up and down within a predetermined temperature range; And a movable contact 57 and a fixed contact 58 that are connected to each terminal 55 in the terminal portion 54 and electrically connect or disconnect the terminal 55 according to the vertical movement of the switch means.

이에 따라, 종래의 수온센서 및 릴레이 기능을 통합하여 일체로 형성되는 간결한 구조를 이루고 전자부품을 사용하지 않아 작동의 신뢰성을 제고하는 효과가 있다.Accordingly, the conventional water temperature sensor and the relay function is integrated to form a concise structure that is integrally formed, and there is an effect of improving the reliability of the operation without using electronic components.
