Description

진공스위치{Vaccum switch}Vacuum switch

본 발명은 전기적으로 회로를 단속시키는 스위치에 관한 것으로, 특히 자석의 반발력을 이용하여 스위치 절환이 가능하도록 하고, 이로 인해 접속단자측의 진공 밀폐구조가 가능하도록 한 진공스위치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch that electrically interrupts a circuit, and more particularly, to a vacuum switch that enables switching of a switch using a repulsive force of a magnet, thereby enabling a vacuum sealing structure on the connection terminal side.

일반적으로 스위치는 전기적인 회로에서 회로를 온(on)/오프(off)시켜주는 역할을 한다. 스위치는 회로와 연결되는 단자를 갖는 몸체와, 절환 위치에 따라 회로를 단속시켜주는 버튼으로 크게 나눌 수 있다. 따라서 버튼의 절환위치에 따라 회로의 단속이 이루어지므로 회로 접점부에서는 전기적인 저항이 일어나고, 이로 인해 전기스파크가 발생될 염려가 크다.In general, switches serve to turn circuits on and off in electrical circuits. The switch can be broadly divided into a body having a terminal connected to the circuit, and a button for controlling the circuit according to the switching position. Therefore, since the circuit is interrupted according to the switching position of the button, an electrical resistance occurs at the circuit contact portion, which causes a great risk of electric spark.

이러한 전기스파크는 회로의 설치 환경에 따라 전기적 회로안정성을 위협하는 위험한 요소로 작용할 수 있다. 따라서 접점부에서는 밀폐구조가 바람직하다. 또한 접점부가 밀폐구조가 되면 이물질의 침입이 근본적으로 차단되어 동작성이 양호해지고 안정된 회로의 단속이 가능하다.Such an electric spark may act as a dangerous factor that threatens electrical circuit stability depending on the installation environment of the circuit. Therefore, a closed structure is preferable at the contact portion. In addition, when the contact portion becomes a sealed structure, intrusion of foreign matter is fundamentally blocked, so that the operability is improved and a stable circuit can be interrupted.

따라서 본 발명은 상기와 같은 사정을 감안하여 창출된 것으로, 자석의 반발력을 이용하여 스위치 절환이 가능하도록 하고, 이로 인해 접속단자측의 진공 밀폐구조가 가능하고, 전기적 회로 안정성을 높일 수 있도록 한 진공스위치를 제공함에 그 목적이 있다.Therefore, the present invention was created in view of the above circumstances, and it is possible to switch the switch by using the repulsive force of the magnet, thereby enabling the vacuum sealing structure of the connection terminal side, and the vacuum to improve the electrical circuit stability The purpose is to provide a switch.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시 예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 진공스위치의 구성도이고, 도 2는 도 1의 평면도이고. 도 3은 도 1에서 가동버튼의 절환위치에 따른 작동상태도이다.1 is a block diagram of a vacuum switch according to the present invention, Figure 2 is a plan view of FIG. 3 is an operating state diagram according to the switching position of the movable button in FIG.

도 1 내지 도 3에서와 같이 본 발명의 진공스위치(10)는 스위치 케이스(20)와 가동버튼(30) 및 접속단자(40)로 구성된다.1 to 3, the vacuum switch 10 of the present invention is composed of a switch case 20, a movable button 30 and the connection terminal 40.

스위치 케이스(20)는 플라스틱으로 제작되어 있고, 중앙에 격벽(22)을 갖고, 격벽(22)을 기준으로 대향하는 스위치 조작실(24)과, 회로단자(25)를 갖는 접속단자실(26)이 구비되어 있다. 회로단자(25)는 일부가 접속단자실(26)에 노출되어 있고 타부가 스위치 케이스(20)의 외부로 노출되어 있다.The switch case 20 is made of plastic, has a partition wall 22 in the center, and has a switch operation chamber 24 facing the partition wall 22 and a connection terminal room 26 having a circuit terminal 25. ) Is provided. Part of the circuit terminal 25 is exposed to the connection terminal chamber 26, and the other part is exposed to the outside of the switch case 20.

가동버튼(30)은 구동자석(32)을 갖고 스위치 케이스(20)의 스위치 조작실(24)에 이동가능하게 설치되어 있다. 가동버튼(30)에는 손 등으로 조작되기 위해 스위치 케이스(20)외부로 노출된 노작노브(33)가 포함되어 있고, 조작노브(33)는 안내장공(20a)에 이동 가능하게 삽입되어 있다.The movable button 30 has a drive magnet 32 and is provided to be movable in the switch operation room 24 of the switch case 20. The movable button 30 includes a work knob 33 exposed to the outside of the switch case 20 to be operated by hand or the like, and the operation knob 33 is inserted into the guide slot 20a so as to be movable.

본 실시예에서 조작노브(33)는 상방으로 돌출되어 구성되었으나 경우에 따라 스위치 조작실(24)의 전면 또는 후면으로 설치될 수 있음은 물론이다.In the present embodiment, the operation knob 33 is configured to protrude upward, but in some cases, may be installed to the front or rear of the switch operation room 24.

접속단자(40)는 구동자석(32)과 반발하는 피동자석(42)과, 접점(44)을 갖고 스위치 케이스(20)의 접속단자실(26)에 이동가능하게 설치되어 있다.The connection terminal 40 has a driving magnet 42 and a driven magnet 42 which repels, and a contact 44 is provided to be movable in the connection terminal chamber 26 of the switch case 20.

여기서 구동자석(32)과 피동자석(42)은 서로 동일한 N극(또는 S극)으로 마주하도록 각기 가동버튼(30)과 접속단자(40)에 배치되고, 가동버튼(30)의 절환위치에 따라 접속단자(40)가 그 반대 위치로 절환되어 회로단자(25)의 회로를 단속시키게 되어 있다.Here, the driving magnets 32 and the driven magnets 42 are respectively disposed on the movable button 30 and the connecting terminal 40 so as to face each other with the same N pole (or S pole), and at the switching position of the movable button 30. Accordingly, the connection terminal 40 is switched to the opposite position to interrupt the circuit of the circuit terminal 25.

미설명부호 '5'는 가동버튼(30)을 지지하는 '판 스프링'이다.Reference numeral '5' is a 'plate spring' for supporting the movable button 30.

바람직하게는 접속단자실(26)은 진공 밀폐된 구조로 구성된다.Preferably, the connection terminal chamber 26 is comprised by the vacuum sealed structure.

이와 같이 구성된 진공스위치의 작동을 설명한다.The operation of the vacuum switch configured as described above will be described.

먼저, 도 1과 같이 가동버튼(30)이 좌측으로 이동한 상태에서는 접속단자(40)는 우측으로 이동 완료한 상태가 된다.First, in the state where the movable button 30 is moved to the left side as shown in FIG. 1, the connection terminal 40 is in a state where the movement is completed to the right side.

이 상태에서 가동버튼(30)을 도 3과 같이 우측으로 이동 절환시키면 접속단자(40)는 그 반대방향인 좌측으로 이동 절환된다. 즉, 가동버튼(30)이 행정 거리의 1/2을 넘어가게 되면 구동자석(32)과 피동자석(42)간에는 동일한 극으로 최대 반발력이 생기게 된다.In this state, when the movable button 30 is shifted to the right as shown in FIG. 3, the connection terminal 40 is shifted to the left in the opposite direction. That is, when the movable button 30 exceeds 1/2 of the stroke distance, the maximum repulsion force is generated between the driving magnet 32 and the driven magnet 42 with the same pole.

이러한 반발력은 접속단자(40)를 측방으로 이동시키는 힘(옆으로 미는 힘)을 발생시켜 접속단자(40)의 위치를 이동시키게 된다.This repulsive force generates a force (lateral pushing force) for moving the connection terminal 40 laterally to move the position of the connection terminal 40.

이와 같이 진공스위치(10)는 가동버튼(30)의 절환 위치에 따라 구동자석(32) 과 피동자석(42)간의 반발력으로 그 반대 방향으로 이동하는 접속단자(40)에 의해 회로단자(25)에 연결된 회로의 단속이 이루어진다.As described above, the vacuum switch 10 is connected to the circuit terminal 25 by the connection terminal 40 moving in the opposite direction by the repulsive force between the driving magnet 32 and the driven magnet 42 according to the switching position of the movable button 30. Interruption of the circuit connected to is made.

이같이 진공스위치(10)는 가동버튼(30)과 무접촉으로 접속단자(40)가 이동 절환되면서 온/오프 스위치 기능을 수행하기 때문에 접속단자실(26)을 밀폐된 진공구조로 구성할 수 있는 것이다.As such, the vacuum switch 10 performs the on / off switch function by moving the connection terminal 40 in contact with the movable button 30 so that the connection terminal room 26 can be formed in a sealed vacuum structure. will be.

또한 접속단자실(26)의 밀폐 구조로 인해 접점부로 이물질의 침입이 근본적으로 차단되어 회로 동작이 뛰어나고 전기적인 안전성이 향상되는 것이다.In addition, due to the sealed structure of the connection terminal room 26, intrusion of foreign matter into the contact portion is essentially blocked, so that the circuit operation is excellent and the electrical safety is improved.

이와 같이 동작하는 진공스위치(10)는 예시된 도면의 형태에만 한정되는 것은 아니며 다른 형태의 스위치에도 적용이 가능함은 물론이다.The vacuum switch 10 operating in this way is not limited to the illustrated figure, but can be applied to other types of switches.

본 실시예에서 회로단자(25)는 스위치 케이스(20)의 저면에 설치하였으나 접점(44)과 연결될 수 있는 구조이면 접속단자실(26)의 다른 위치에 설치할 수도 있다.In this embodiment, the circuit terminal 25 is installed on the bottom surface of the switch case 20, but if the structure can be connected to the contact 44 may be installed in other positions of the connection terminal room 26.

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following by those skilled in the art to which the present invention pertains.
