Description

접지 확인 유닛Grounding confirmation unit
본 발명은 접지 확인 유닛에 관한 것으로서, 더욱 상세하게는 어싱패드나 어싱밴드와 같은 어싱부재뿐만 아니라 그 어싱부재에 접촉하고 있는 인체의 접지 여부를 확인할 수 있는 접지 확인 유닛에 관한 것이다.The present invention relates to a grounding confirmation unit, and more particularly, to a grounding confirmation unit capable of checking not only an acceleration member such as an ashing pad or an acceleration band but also a human body contacting the acceleration member.
지구상의 모든 만물에는 필연적으로 전기가 존재하며, 전기는 보통 플러스(+)와 마이너스(-)의 균형(balance)을 유지하고 있으나, 어떤 원인에 의해 균형이 깨어졌을 때에 정전기가 발생하게 된다.Electricity is inevitably present in all things on earth, and electricity usually maintains a balance of plus (+) and minus (-), but static electricity is generated when the balance is broken for some reason.
인체에도 여러 가지 이유로 정전기가 발생하고 있으며, 인체에 3시간 동안 정전기가 체류하면 체내 칼슘량이 10% 소모되고, 혈당가가 3% 증가한다고 알려졌다.Static electricity is generated in the human body for various reasons, and when static electricity stays in the human body for 3 hours, it is known that the amount of calcium in the body is consumed by 10% and the blood sugar value is increased by 3%.
특히, 인체의 정전기는 반도체 소자를 다루는 작업에서는 반도체 소자를 파괴하거나 손상시키고, 인화성 물질을 다루는 작업에서는 점화원이 되는 등 심각한 결과를 초래할 수 있다.Particularly, the static electricity of the human body may cause serious consequences such as destroying or damaging the semiconductor element in the operation of handling the semiconductor element and becoming an ignition source in the operation of handling the flammable material.
또한, 정전기에 의한 칼슘 파괴로 인해 산성화 체질로 바뀌게 되고, 질병에 대한 저항력이 감소하며, 피로를 쉽게 느끼게 된다.In addition, due to the destruction of calcium due to static electricity, the acidic constitution changes, resistance to disease decreases, and fatigue is easily felt.
정전기는 밤에 자고 있는 동안에도 몸에 축적되는데, 인체는 이러한 정전기의 영향으로 숙면을 취할 수 없고, 다양한 질병의 원인으로 작용할 수 있다.Static electricity accumulates in the body while sleeping at night. The human body can not take a good night sleep due to the effect of this static electricity, and can act as a cause of various diseases.
한편, 전기에너지를 이용하는 전기ㆍ전자제품들은 전기에너지에 의해 전계(電界) 및 자계(磁界)가 발생하고, 상기 전계에 의해 세력의 차이는 있지만 유해전자파가 각각 방출되면서 주변의 사물이나 생명체에 각종 해악을 끼치고 있다.On the other hand, electrical and electronic products using electric energy generate electric fields and magnetic fields by electric energy, and although the electric field causes a difference in electric power, harmful electromagnetic waves are released, It is harmful.
특히, 전기에너지의 열원을 이용하여 난방하는 전기매트는 사용자가 그 위에 눕거나 앉아서 사용하게 되고, 또한 사용자의 체중이 전열판을 누르는 구조이므로 상기 전열판과 인체가 근접하게 된다.Particularly, an electric mat for heating by using a heat source of electric energy has a structure in which the user lie down or sit on it, and the weight of the user presses the heat transfer plate, so that the heat transfer plate and the body come close to each other.
따라서 전계 및 다량의 유해전자파가 인체로 직접 유도되어 매우 해로운 작용을 하게 된다.Therefore, an electric field and a large amount of harmful electromagnetic waves are directly induced into the human body, and the harmful electromagnetic wave is very harmful.
따라서 전기매트의 전열판 상부에 도전체로 된 연질의 차폐판, 이를테면 알루미늄 박(箔)이나 금속호일 또는 금속가루를 고정화시킨 시트류 또는 금속선을 촘촘히 엮은 차폐판 등을 설치한 다음 전원콘센트 및 전원플러그를 통하여 제공되는 접지선(일반 가정에 공급되는 상용 교류전원은 감전의 위험으로부터 인체를 보호하기 위하여 뉴트랄선과 핫선 이외에 별도의 접지선이 제공됨)과 연결되도록 회로를 구성하여 전계 및 유해전자파의 차폐(Shield)를 달성하고 있다.Therefore, a flexible shielding plate made of a conductive material such as an aluminum foil, a sheet fixed with a metal foil or a metal powder, or a shield plate having a metal wire tightly stitched on the electric heating plate of the electric mat, The shielding of the electric field and harmful electromagnetic waves is performed by constructing a circuit to be connected to the grounding line provided (the commercial AC power supply supplied to the general household is connected to a separate ground wire in addition to the neural line and the hot line in order to protect the human body from the danger of electric shock) .
또한, 대한민국 특허등록 제10-0563810호에는 개인용 신체 접지 장치가 개시되어 있는 바, 이 선행특허는 인체로부터 비정상적인 전기 전하를 수집 및 제거하기 위한 개인용 접지 장치로 접지패드를 포함하여, 상기 접지패드는 탄소섬유층 및 상기 탄소섬유와 도전적으로 접촉하면서 상기 탄소섬유층을 실질적으로 가로질러 연장하는 전도부를 포함하고, 상기 전도부에 접지 리드선이 도전적으로 연결되어 구성된다.Korean Patent Registration No. 10-0563810 discloses a personal body grounding apparatus, which is a personal grounding apparatus for collecting and removing abnormal electrical charges from a human body, including a grounding pad, A carbon fiber layer and a conductive portion extending substantially across the carbon fiber layer in a conductive contact with the carbon fiber layer, and a ground lead wire is electrically connected to the conductive portion.
또한, 반도체와 같은 각종 산업 현장에서 인체에서 발생되는 정전기 제어대책의 일례로서, 어싱밴드를 착용하는 방법이 있다,As an example of countermeasures against static electricity generated in the human body in various industrial fields such as semiconductors, there is a method of wearing an ashing band,
이 어싱밴드를 착용하는 방법은, 팔목에 착용한 어싱밴드를 접지선에 연결하여 인체와 접지선을 전기적으로 연결함으로써 인체의 움직임으로 인해 발생되는 정전기를 방전하도록 한 것이다.The method of wearing the ascending band is to connect the human body and the ground wire by connecting the ascending band worn on the cuff to the ground wire to discharge the static electricity generated by the movement of the human body.
그런데 종래의 이와 같은 접지 확인 방법은 전기매트나 접지패드 또는 어싱밴드(이하 어싱부재로 통칭함)는 어싱부재가 현재 실제 접지되었는지 확인할 수 있는 방법이 없었고, 다만 어싱부재의 전도성부재(금속선)에 테스터기를 접촉시켜 테스터기에서 알람이나 빛과 같은 신호가 출력되는 경우 접지되었음을 확인하는 방법이 있으나, 별도로 테스터기를 구비해야 번거로움과 테스터기를 어싱부재에 접촉시켜 접지를 확인해야 하는 불편함이 있었다.However, in the conventional grounding confirmation method, there is no method for confirming whether or not the sensing member is actually grounded at the time of the electric mattress, the grounding pad, or the assisting band (hereinafter referred to as the assisting member) There is a method of confirming that the tester is grounded when a signal such as an alarm or light is output from the tester. However, it is inconvenient to check the ground by contacting the tester with the tester.
또한, 사용자가 어싱부재에 접촉한 상태에서 사용자의 몸이 현재 어싱부재를 통해 접지되었는지 - 사용자의 몸 자체가 접지되었는지 - 알 수 없는 문제점이 있었다.Further, there is a problem that the user's body is grounded via the current sensing member in the state where the user touches the urging member, and the user's body is grounded.
본 발명은 상술한 문제점을 해결하기 위하여 안출된 것으로, 스마트어싱플러그와, 2접점의 버튼단자와 3극잭(오디오 잭)을 연결한 접지확인코드를 이용하여 어싱부재의 접지 상태뿐만 아니라 그 어싱부재에 접촉된 인체의 접지 상태를 확인할 수 있고, 이를 통해 별도의 테스터기를 구비하여 어싱부재의 전도성부재에 접촉시키지 않아도 되어 편리한 접지 확인 유닛을 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been conceived to solve the above-mentioned problems, and it is an object of the present invention to provide a smart ear plug, a grounding check cord connecting a button terminal of two contacts and a triple jack (audio jack) And it is an object of the present invention to provide a convenient grounding confirmation unit which is provided with a separate tester and does not have to be in contact with the conductive member of the assisting member.

먼저 도 5에서 소켓부(42)에 3극잭(60)이 삽입되지 않으면 스마트어싱플러그의 (+)전원과 (-)전원이 전기적으로 연결되어 있지 않아서 스마트어싱플러그의 전원이 OFF되어 있다가, 소켓부(42)에 3극잭(60)이 삽입되면 (+)전원과 (-)전원이 전기적으로 연결되어 스마트어싱플러그의 전원이 ON된다.5, when the three-pole jack 60 is not inserted into the socket portion 42, the (+) power source and the (-) power source of the smart assyting plug are not electrically connected to each other, When the three-pole jack 60 is inserted into the socket portion 42, the (+) power source and the (-) power source are electrically connected to turn on the smart assyting plug.
즉, 스마트어싱플러그 전원의 스위칭 기능을 3극잭(60)으로 대체할 수 있다.That is, the switching function of the power source of the smarting plug can be replaced with the three-pole jack 60.
특히, 전원부(46)가 배터리로 구성되어 있는 경우에는 유통시 전원 소비를 방지할 수 있다.Particularly, when the power supply unit 46 is constituted by a battery, it is possible to prevent power consumption during distribution.
다음 도 7에서 4극잭(60')을 사용하는 경우에는 4극 중 3번째 접지전극과 사용하지 않는 4번째 전극을 쇼트시킨 후 소켓부(42')에 삽입하여 스위치 기능을 수행할 수 있다.In the case of using the quadrupole jack 60 'in FIG. 7, the third ground electrode of the four poles and the fourth electrode which is not used may be shorted and inserted into the socket portion 42' to perform a switching function.
