수중센서용 기판 하우징{Circuit board housing for submerged sensor}Circuit board housing for submerged sensor

본 발명은 염분이나 오염물의 농도, 수온 또는 전기전도도 등 해수 및 담수의 물리·화학량 측정에 사용되는 수중센서(水中 Sensor)에 있어서, 감지부와 연결되는 전자회로 기판을 수납하기 위한 기판 하우징(Housing)에 관한 것으로, 원통형의 본체와 이에 결합되는 마개로 구성되며, 본체의 외주면과 마개의 내주면에 각각 내접홈과 외접홈이 형성되어 이들 사이에 고정선이 삽입됨으로써 본체와 마개가 고정되도록 한 것이다.The present invention relates to a substrate housing for accommodating an electronic circuit board connected to a sensing unit in an underwater sensor used for measuring physical and chemical quantities of seawater and freshwater such as salt or pollutant concentration, water temperature or electrical conductivity. It consists of a cylindrical body and a stopper coupled thereto, and the inner and outer grooves are formed on the outer circumferential surface of the body and the inner circumferential surface of the stopper so that the main body and the stopper are fixed by inserting a fixed line therebetween.

해수 또는 담수의 물리·화학량 측정은 시료를 채취하여 실험실에서 분석하는 방법과 현장에서 실시간으로 측정하는 방법으로 분류될 수 있는데, 이중 실시간 측정 방법에 있어서 반드시 필요한 것이 측정치를 전기신호화하여 출력하는 수중센서이다.The measurement of physical and chemical quantities of seawater or freshwater can be classified into the method of taking a sample and analyzing it in the laboratory and the real-time measurement in the field. Sensor.

수중센서는 물과 직접 접촉되어 측정을 수행하는 감지부와, 미약한 신호를 증폭하거나, 아날로그신호를 디지털신호로 변환하는 등 감지부로부터 발생되는 신호를 처리하는 전자회로 기판 등으로 구성된다.The underwater sensor is composed of a sensing unit performing direct measurement in contact with water and an electronic circuit board for processing signals generated from the sensing unit such as amplifying a weak signal or converting an analog signal into a digital signal.

이러한 수중센서에 있어서, 감지부에서 자체 발생되는 전기신호가 미약하여 전자회로 기판과 감지부를 연결하는 신호선의 길이에 제한이 있을 수 밖에 없으므로, 도 1에서와 같이, 기판(12)을 원통형의 본체(10)와 마개(20)로 구성된 밀폐 하우징에 수납하여 감지부(13)와 함께 수중에 투입하는 방식이 일반적으로 사용되고 있다.In such an underwater sensor, since the electric signal generated by the sensing unit is weak and there is no limit to the length of the signal line connecting the electronic circuit board and the sensing unit, as shown in FIG. 1, the substrate 12 has a cylindrical body. It is generally used to store in a sealed housing composed of the 10 and the stopper 20 and put it in the water together with the sensing unit 13.

그러나, 도 1과 같은 종래의 하우징은 그 본체(10)와 마개(20)가 나사식으로 체결되는 구조로서, 마개(20)를 회전시켜 본체(10)에 결합하는 과정에서 필연적으로 기판(12)과 연결된 신호선(15)이 꼬일 수 밖에 없는 문제점이 있었으며, 수중센서의 유지관리를 위하여 반복적으로 마개(20)를 결합 및 해체하는 과정에서 신호선(15)의 꼬임과 풀림이 반복되게 되어, 기판(12)과 신호선(15)간의 접속불량을 유발함은 물론, 장기적으로는 수중센서 자체의 내구성에도 치명적인 악영향을 미치게 되는 심각한 문제점이 있었다.However, the conventional housing as shown in FIG. 1 is a structure in which the main body 10 and the stopper 20 are screwed together, and inevitably the substrate 12 is rotated in the process of coupling the stopper 20 to the main body 10. ), There was a problem that the signal line 15 connected to the twisted line and the twisting and loosening of the signal line 15 in the process of repeatedly coupling and dismantling the stopper 20 for the maintenance of the underwater sensor, the substrate In addition to causing a poor connection between the (12) and the signal line 15, in the long term there was a serious problem that has a fatal adverse effect on the durability of the underwater sensor itself.

본 발명은 전술한 문제점을 감안하여 창안한 것으로, 하우징 본체의 외주면에 내접홈을 형성하고, 마개의 내주면에는 외접홈을 형성하여, 이들 내접홈과 외접홈 사이에 고정선을 삽입함으로써 마개나 본체를 회전시키지 않고도 이들을 체결할 수 있도록 한 것이다.The present invention has been made in view of the above-described problems, and forms an internal groove on the outer circumferential surface of the housing body, and forms an external groove on the inner circumferential surface of the stopper, thereby inserting a stopper or the main body by inserting a fixed line between the internal and external grooves. They can be fastened without rotating.
