본 고안은 마그네틱 스윗치에 관한 것이다.The present invention relates to a magnetic switch.

전류제어용으로서 통상적으로 사용되는 마그네틱 스윗치는 밀폐된 공간내에 가동접점과 고정접점을 설치하고, 전자석으로써 가동접점을 흡인하여 고정접점에 접촉되도록 한 구성으로 되어 있다.Magnetic switches commonly used for current control are constructed so that movable contacts and fixed contacts are provided in a closed space, and the movable contacts are attracted with an electromagnet to come into contact with the fixed contacts.

상기한 종래의 마그네틱 스윗치는 주로 대전류제어용에 쓰이기 때문에 사용중 가동접점과 고정접점이 접촉할때 스파아크가 발생하여 접점이 손상되거나, 카아본이 피착되어 접촉불량을 일으키는 결점이 있다.Since the above-described conventional magnetic switch is mainly used for high current control, sparks are generated when the movable contact and the fixed contact come into contact with each other during use, and thus the contact is damaged or the carbon is deposited, resulting in a poor contact.

본 고안은 상술한 결점을 해결하기 위하여 안출된 것으로서 이를 첨부도면에 따라 상세히 설명하면 다음과 같다.The present invention has been devised to solve the above-described drawbacks and will be described in detail according to the accompanying drawings.

제1도는 본 고안의 일실시예로 도시하는 것으로 도면중 부호1은 밀봉하우징이고, 2와 3은 밀봉하우징(1)의 상, 하단에 접속되는 단자이다. 단자(2)에는 용수철(4)이 현수연결하고, 이 용수철(4)의 종단에는 가동접점(5)가 부착된다.1 is a diagram illustrating an embodiment of the present invention. In the drawings, reference numeral 1 is a sealing housing, and 2 and 3 are terminals connected to upper and lower ends of the sealing housing 1. A spring 4 is suspended from the terminal 2, and a movable contact 5 is attached to the end of the spring 4.

그리고 밀봉하우징(1)의 내부에는 수은(6)이 수용된다. 수은(6)의 레벨은 가동접점(5)와 일정간격 "L"을 유지하는 정도로 충전된다. 수은(6)은 단자(3)과 전기적인 접촉이 되어 고정접점을 형성하게 된다. 밀봉하우징(1)의 내부공간은 질소와 같은 볼활성 개스를 충전하여 수은(6)의 산화를 방지해 준다.And the mercury 6 is accommodated in the sealing housing 1. The level of mercury 6 is charged to such an extent that it maintains a constant distance "L" with the movable contact 5. Mercury 6 is in electrical contact with the terminal 3 to form a fixed contact. The inner space of the sealing housing 1 is filled with a ball activated gas such as nitrogen to prevent oxidation of the mercury 6.

수은(6)의 레벨과 대등한 위치로 밀봉하우징(1)의 외측에는 여자코일(7)이 설치된다.An excitation coil 7 is provided outside the sealing housing 1 at a position comparable to the level of mercury 6.

여자코일(7)은 독자적으로 스윗치(SW)를 보유한다.The excitation coil 7 independently has a switch SW.

상술한 구성의 본 고안은 단자(2), (3)측에 피제어부 A를 전기적으로 접속시켜 사용한다. 피제어부 A의 신호에 의해 또는 작업자의 조작에 의해 스윗치(SW)가 스윗치-온으로 된다면 여자코일(7)은 통전되어 자력을 발생하게된다.The present invention having the above-described configuration is used by electrically connecting the controlled part A to the terminals 2 and 3 side. When the switch SW is switched on by the signal of the controlled unit A or by the operator's operation, the excitation coil 7 is energized to generate magnetic force.

이때의 자력은 주지된 바와 같이 가동접점(5)를 흡인시켜 주므로, 가동접점(5)는 용수철(4)의 탄성력에 저항하여 하강되면서 수은(6)에 잠겨지므로 전기적인 스윗치-온이 행해지게 된다.Since the magnetic force at this time attracts the movable contact 5 as is well known, the movable contact 5 is lowered to resist the elastic force of the spring 4 so as to be locked in the mercury 6 so that electrical switch-on is performed. do.

만약, 여자코일(7)로부터의 자력이 소실되면, 즉 스윗치(SW)가 스윗치-오프되어지면, 가동접점(5)는 용수철(4)의 탄성복원력에 의해 원래위치로 복귀하여 수은(6)과 간격 "L"을 이루게 된다.If the magnetic force from the excitation coil 7 is lost, that is, if the switch SW is switched off, the movable contact 5 returns to its original position by the elastic restoring force of the spring 4 and the mercury 6 And the interval "L".

상기과정에 있어서 가동접점(5)가 수은(6)에 전기적으로 접촉할때 스파아크가 발생하더라도, 수은(6)은 유동성금속이므로 접점이 손상되는 일은 없고 카아본과 같은 불순물이 접점에 피착되는 일도 없으며, 가동접점(5)는 표면의 일정면만을 접촉부로 하는 것이 아니고 전체표면이 접촉부로 되는 것이므로 접촉상태가 양호하다는 이점을 나타내며, 밀봉하우징(1)의 내부에 불활성 개스를 충전해주는 것에 의해 수은(6)의 산화가 방지되어 사용수명에도 손색이 없는 장점을 갖는다.In the above process, even if sparking occurs when the movable contact 5 is in electrical contact with the mercury 6, the mercury 6 is a fluid metal so that the contact is not damaged and impurities such as carbon are deposited on the contact. Since the movable contact 5 does not use only a certain surface of the surface as a contact portion, but the entire surface becomes a contact portion, it shows an advantage that the contact state is good, and by filling the inside of the sealing housing 1 with an inert gas. The oxidation of mercury (6) is prevented has the advantage of inferior to the service life.

제2도는 본 고안의 다른 실시예를 도시하는 것으로 상기 실시예와 동일한 부분은 동일부호로 표시되어 있다.Figure 2 shows another embodiment of the present invention, the same parts as the above embodiment are denoted by the same reference numerals.

밀봉하우징(1)의 내부에 수은(6)을 수용하고, 가동접점(5)를 수은(6)과 간격 "L"을 이루도록 설치하며, 밀봉하우징(1)의 외주에 여자코일(7)을 설치해 두는 점은 상기 실시예와 동일하다. 그러나, 여자코일(7)의 내측으로 철심코어(70)이 개재되고, 이 철심코어(70)은 밀봉하우징(1)의 내부에 위치하여 중앙의 절연관(71)에 가동접점(5)를 슬라이드 가능하게 삽입지지해 주고 있다. 또한 가동접점(5)는 철심코어(70)의 상면에 지지되는 용수철(4)의 탄성력을 받아 항상 위로 치솟는 자세로 놓여지고, 가동접점(5)의 상단에는 흡착면(50)이 일체고정되어 있다.The mercury 6 is accommodated inside the sealed housing 1, the movable contact 5 is provided to form an interval "L" with the mercury 6, and the excitation coil 7 is provided on the outer circumference of the sealed housing 1. The point of installation is the same as that of the said Example. However, an iron core core 70 is interposed inside the excitation coil 7, and the iron core core 70 is positioned inside the sealing housing 1 to provide a movable contact 5 to the central insulation tube 71. It is slidably inserted. In addition, the movable contact (5) is always placed soaring upwards under the elastic force of the spring (4) supported on the upper surface of the core core 70, the suction surface 50 is fixed to the upper end of the movable contact (5) integrally have.

가동접점(5)은 리이드선(51)을 경유하여 단자(2)에 전기적으로 접속된다. 가동접점(5)에 부여된 미설명부호 52는 가동접점(5)의 상향위치를 규제하는 스톱퍼이며, 다른 미설명 부호 8은 밀봉하우징(1)의 외측에 부착되는 냉각판이다.The movable contact 5 is electrically connected to the terminal 2 via the lead wire 51. Reference numeral 52 assigned to the movable contact 5 is a stopper for restricting the upward position of the movable contact 5, and another reference numeral 8 is a cooling plate attached to the outside of the sealing housing 1.

상기한 구성에 의해 여자코일(7)이 여자력을 발생하면 철심코어(70)이 자화되어 가동접점(5)의 흡착편을 흡인하는 것에 의해 가동접점(5)와 수은(6)이 전기적으로 접촉되어짐은 상기 실시예와 동일하다.When the excitation coil 7 generates an excitation force by the above-described configuration, the iron core core 70 is magnetized to suck the suction piece of the movable contact 5 so that the movable contact 5 and the mercury 6 are electrically connected. Contact is the same as in the above embodiment.

만약, 제어전류가 대용량의 것이라면 상기 과정에서 스파아크 발생에 기인하여 밀봉하우징(1)의 내부온도는 상승하게 될 것이다.If the control current is a large capacity, the internal temperature of the sealing housing 1 will rise due to the sparking in the process.

주지된 바와 같이 수은(6)은 온도변화에 대한 체적변동이 심한 물질이므로 밀봉하우징(1)의 내부온도가 상승하면 체적이 팽창하여 수은(6)의 레벨이 높아져서 간격 "L" 에 이상이 생기게 된다. 따라서 밀봉하우징(1)의 내부온도를 일정온도로 유지해주어야 할 필요가 생기며, 본 고안에서는 이것을 방열판(8)에 의존하여 냉각시켜 준다.As is well known, mercury 6 is a material with a large volume change due to temperature change, so when the internal temperature of the sealing housing 1 rises, the volume expands and the level of mercury 6 rises, causing an abnormality in the interval "L". do. Therefore, it is necessary to maintain the internal temperature of the sealing housing 1 at a constant temperature, and in the present invention, it is cooled depending on the heat sink 8.

따라서 이 실시예에 따르면 밀봉하우징(1)의 내부온도 변화에는 오작동의 결함이 생기지 않는 양질의 마그네틱 스윗치를 얻을 수 있게 되는 것이다.Therefore, according to this embodiment, it is possible to obtain a high-quality magnetic switch that does not cause malfunctions in the internal temperature change of the sealing housing 1.
